Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the lifting desks with two or more single-column support structures have difficulties in synchronizing the lifting legs, or the structure is complex, the manufacturing cost is high, and the user is very laborious when the load is large, although the lifting can be realized synchronously. The problem is to design an external gas storage cylinder (tank) linkage gas spring synchronous lifting table with simple structure, low cost, convenient synchronization, and easy up and down use

Embodiment 1

[0038] Such as figure 1 , 2 , 5, and 6.

[0039] An external gas storage cylinder or tank linkage synchronous lifting table based on the principle of gas springs, which includes a desktop 1 and a base 4. The desktop 1 is connected through at least two (this embodiment uses two as an example for illustration, and multiple connections can be see Figure 9 As shown) the lifting leg 3 made on the basis of the gas spring principle is installed on the base 4, and the lifting leg 3 is composed of a piston rod 77, a cylinder body 33 and a power cylinder or a tank 57, and the rod cavity of one cylinder body 33 is connected with the other While the rodless cavity of the cylinder body 33 communicates with the storage chamber 88 of the power cylinder or tank 57 as the driving power, the rodless cavity of the last cylinder body 33 communicates with the rodless cavity of the first cylinder body 33 At the same time, it is connected with the storage chamber 88 of the last power cylinder or...

Embodiment 2

[0060] Such as image 3 , 4 , 5, and 6.

[0061] The difference between this embodiment and Embodiment 1 is that the gas springs are installed one positive and one reverse (one gas spring has a rod cavity connected to the other gas spring without a lever cavity), and the piston rod 77 of the gas spring 3 in one lifting leg 2 is connected to the other. The base 4 is fixedly connected, and the rodless end of the gas spring 3 is connected to the desktop 1 through the extended arm support 5; the rodless end of the gas spring 3 in the other lifting leg 2 is fixedly connected to the base 4, and the piston rod 77 of the gas spring 3 The extended arm support 5 is connected with the desktop 1 . The rod chamber of the gas spring installed in the forward direction and the rodless chamber of the gas spring installed in the reverse direction are connected through the flexible pipe 6. Embodiment 1 is the same.

Embodiment 3

[0063] Such as Figure 7 shown.

[0064] An external gas storage cylinder or tank linkage synchronous lifting table based on the gas spring principle, which includes a desktop 1 and a base 4, the desktop 1 is installed on the base 4 through at least two lifting legs 3 made based on the gas spring principle, the The lifting leg 3 is composed of a piston rod 77, a cylinder body 33 and a power cylinder or a tank 57. The rod cavity of the cylinder body 33 is connected with the rodless cavity through a stop valve, and the stop valve is controlled by a valve installed in the piston rod 77. The operating rod, the top of the operating rod is equipped with a valve button 55; as the storage chamber 88 of the power cylinder or tank 57 that drives the rising power of the piston rod communicates with the cavity of the installation control rod in the piston rod 77 through the pipeline 6, the cavity The lower end communicates with the rod cavity of the cylinder body 33, and the piston in th...

Abstract

The invention relates to an external air reservoir or tank linkage synchronous lifting table based on the principle of a gas spring. The external air reservoir or tank linkage synchronous lifting table includes a table top (1) and a base (4), and is characterized in that the table top is installed on the base through at least two lifting legs (3) made based on the principle of the air spring, each lifting leg is composed of a piston rod (77), a cylinder body (33) and a power air cylinder or tank (57), a rod cavity of one of the cylinder bodies (33) communicates with storage cavities of the power air cylinders or tanks (57) as the driving power while communicating with a rodless cavity of another one of the cylinder bodies (33), a rod cavity of the last cylinder body (33) communicates with a storage cavity of the last power air cylinder or tank (57) while communicating with a rodless cavity of the first cylinder body (33), high-pressure gas in power cavities 99 of the power air cylinders or tanks (57) provides power to lift the table top, and the high-pressure gas is compressed and stores energy when the table top descends. According to the external air reservoir or tank linkage synchronous lifting table, the structure is simple, the cost is low, manufacturing is convenient, and the synchronous lifting and arbitrary height locking properties are good.

Description

technical field [0001] The invention relates to a piece of furniture, in particular to an external gas storage cylinder (tank) linkage gas spring synchronous lifting table capable of ensuring synchronous lifting, specifically an external gas storage cylinder or tank linkage synchronous lifting table based on the gas spring principle. Background technique [0002] People use various desks when they are working and studying. It is easy to cause cervical spine, lumbar spondylosis and other diseases when using ordinary traditional desks for a long time to sit and work and study. Properly changing the posture of standing and using desks can effectively prevent cervical spine. Spondylosis, lumbar disease, etc. Scientific research shows that the harm of sitting for a long time is even greater than the harm caused by smoking, and insisting on standing for a long time can consume a certain amount of extra calories, maintain body shape and weight, and help the overall health of the bod...
