The role of office ergonomic chair in preventing cervical spondylosis

The incidence of cervical spondylosis is increasing nowadays. Most of the time it is because we are all down to work, saying that it is harmful to play mobile phones and computers. In fact, there are many factors, such as transportation, our daily cars. Sudden braking, our usual computer chair is also very bad for cervical spine damage, today we come to talk about the office ergonomic chair.

The office ergonomic chair can be understood literally as a tool to handle copywriting and other tasks in our daily work. This does not need to be moved. The computer chair is actually a product that appeared at the end of the last century. The chair used by people who previously specialized in computer work was low at that time. Therefore, a professional person needs to operate several computers and printers at the same time, so he needs to move and Because of the computer relationship, the height needs to be adjusted, so this time the computer chair is very useful.

After understanding the concept of the computer chair, then let's talk about the office chair. Many office spaces are now very small. At this time, there is no need to move. At this time, the wheel is an extra burden, because it will be active. It is necessary to rely on the muscles of the legs and hips and the entire back to pull the chair to prevent it from moving. Then the muscles will fatigue throughout the day, and muscle strains will occur over time. Take the muscle strains of the waist and hips and the distal neck as the Lord.

In addition, because the computer chair is supported by the middle air pressure rod to support the upper chair surface, there is a problem at this time. The link between the middle top rod and the air pressure piece is not fixed and dead. This top rod is movable, so This caused a slight sway of the chair surface. At this time, the hips swayed slightly. For the high head, the sway was large. Due to the sway of the head, the eyes could not see things clearly. The human body will ask me to adjust, which will cause the strain on our neck muscles to increase.

Therefore, for a healthy cervical spine, and for your own quality of life, it is recommended to change to an ordinary four-legged office ergonomic chair. Such a stable structure is helpful for us to relax our muscles while sitting, and get rest, so as not to work hard all the time.

Comparison of metal processing and sheet metal processing technology

       Metal processing is a general term for metal materials. Hardware can be called the mother of industry. Hardware refers to five metal materials: gold, silver, copper, iron, and tin. These materials can be used for sheet metal processing. The products produced by hardware materials are generally divided into two categories: large hardware and small hardware. Large hardware refers to steel plates, steel bars, flat irons, universal angle steels, channel irons and various types of steel materials; while small hardware refers to construction hardware , Tinplate, iron wire, steel wire mesh, etc.

       The difference between metal processing and sheet metal processing

       Sheet metal processing and metal processing are two different forms of processing, and the processes used are also different. So what is the difference between Metal processing and sheet metal processing? Sheet metal processing is generally a comprehensive cold processing process for metal sheets through electric welding, bending, stamping, shearing, etc.; while metal processing uses professional processing machines for cutting processing, in the form of turning, milling, grinding, and processing Center, spark machine and other processing equipment, this is the difference in equipment and technology between the two.

WHY LOTION PUMPS CAN'T REBOUND AFTER PRESSING

First of all, it is necessary to check whether there is a problem with the lotion pumps spring. The effect of the spring on the piston cannot be ignored. If the spring is damaged, it will easily lead to the return stroke of the piston is not in place. slow.

Secondly, check whether the thickness of the lotion pumps piston fits the body. During the movement of the piston, any trace of the gap will cause weak suction, and the material will not be pressed by the head. Since plastics have the properties of thermal expansion and contraction, normal pistons are very important to ensure the quality of lotion pumps.

Finally, let's analyze the body. In view of the scalability of the plastic, if the operation is inappropriate during injection molding, insufficient injection will cut off a thin layer of the body, resulting in uneven inner walls, and the piston is inevitably left during the stamping process Gaps, resulting in failure to discharge.

What are the precautions for sheet metal processing?

        What is Sheet metal processing? Many people's understanding of Sheet metal processing belongs to metal and hardware. But Sheet metal processing is actually a kind of processing technology, it is a kind of processing technology that metal sheet is processed manually or mechanically processed. Sheet metal processing is that some metal sheets are deformed by hand or die stamping to form the desired shape and size, and can be further welded or reduced in mechanical processing to form more complex parts. For example, car shells are Sheet metal processing parts.

       Matters needing attention when processing sheet metal processing manufacturers.

         The daily demand for products processed by Sheet metal processing is increasing, which is also a challenge for Sheet metal processing manufacturers. So what should Sheet metal processing manufacturers pay attention to when processing? Generally, when sheet metal processing manufacturers are processing, they must first let the technicians sort out the place, and if there are debris, they need to be processed in time. Then check whether the things that need to be used during the operation are intact, whether it can be used normally, and whether the link is strong. If there is no problem after all checking, start and use it according to the requirements and procedures.

       Sheet metal processing should pay attention to precision processing, because it has several advantages of precision processing.
       As the society is constantly changing and developing, the processing requirements for Sheet metal processing are gradually increasing, and traditional rough processing can no longer meet people's needs. The current sheet metal processing processing pays more attention to precision processing. The reason why Sheet metal processing pays more attention to precision processing is because of the advantages of precision processing:
To
1. The bending sequence table can be generated automatically.

2. The unfolding precision is high and easy to inspect.

3. The processing efficiency is high, the quality is good, and the process route is simplified.

4. Realize parameterization and improve the efficiency of deployment.

WHAT SHOULD I DO IF THE PERFUME LOTION PUMPS ARE BROKEN?

        Perfume lotion pumps are more troublesome to operate, and the spray head is generally not available after damage. You can buy spray heads combined with perfume at the store. If you can't find a suitable perfume nozzle, you can also buy a new perfume bottle, and then put the perfume in the new bottle, so that it can be used normally.

        Spraying perfume with the correct posture can protect the lotion pumps. Press gently when spraying perfume. Because the perfume spray head is relatively fragile, it will break if you are not careful. The long-term use of the nozzle is related to the method of use. If you spray perfume frequently and press it with brute force, it is very easy to cause the nozzle to slip and cause the nozzle to break.
