[0002] The lift table is a table with a lifting effect. It has begun to be widely used in the market. Its value is to help office people say goodbye to sitting for a long time and achieve standing office.

[0003] The pneumatic lifting tables currently available on the market have the following problems in actual use:

[0004] 1. In actual use, the traditional pneumatic lifting table is often unlocked by a pull rope device. The pull rope itself is relatively fragile. At the same time, the pull rope will naturally damage after being placed for a long time. At this time, the pull rope may be broken during the use of the pneumatic lifting table, and the damage rate during use is high;

[0005] 2. During the use of most pneumatic lifting tables, the lifting tubes used in the pneumatic lifting tables on the market are mostly square tubes. At this time, the square tube pneumatic lifting tables cannot give people an intuitive feeling of the lifting effect, and the appearance response is poor when used. Utility Model Content

[0029] In order to better understand the purpose, structure and function of the utility model, the pneumatic lifting table of the utility model is further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-6 As shown, the pneumatic lifting table of the utility model includes a table top 1, an upper sliding tube 2 is provided at the bottom of the table top 1, an unlocking seat 12 is welded at one end of the upper sliding tube 2, a gas spring lifting switch 11 is installed inside the unlocking seat 12, and a rotating shaft 17 is connected inside the gas spring lifting switch 11. By installing the transmission shaft and utilizing the rotating shaft 17, the gas spring lifting switch 11 and the unlocking switch can be connected, which is very convenient to use. An unlocking wrench 10 is sleeved on the surface of the rotating shaft 17, a spring telescopic rod 13 is installed inside the gas spring lifting switch 11, and a lower sliding tube 3 is installed at the other end of the spring telescopic rod 13. By installing the unlocking wrench 10, the unlocking wrench 10 is utilized to replace the traditional pull rope, which has high strength during use and is not easily damaged.

[0031] The upper sliding tube 2 is internally sleeved with the lower sliding tube 3, and the surface of the lower sliding tube 3 is sleeved with the upper sliding sleeve 14. The surface of the upper sliding sleeve 14 is in contact with the inner wall of the upper sliding tube 2. An anti-rotation ring 15 is provided at one end of the upper sliding sleeve 14. The anti-rotation ring 15 is internally sleeved with the lower sliding tube 3, and the surface of the anti-rotation ring 15 is in contact with the inner wall of the upper sliding tube 2. By installing the anti-rotation ring 15, the anti-rotation ring 15 can be used to prevent the pneumatic lifting table from rotating when it is lifted up and down, and the stability is relatively strong during use.

[0032] An upper fixing plate 16 is welded on the top of the unlocking seat 12, and the top of the upper fixing plate 16 is connected to the table board 1 by bolts. By installing the fixing plate and using the fixing plate to install the table board 1, stability can be provided for the table board 1, and the stability is relatively strong when in use.

[0033] A cross bar 6 is provided at the other end of the downward tube 3, a hole 7 is opened on the top of the cross bar 6, a locking nut 5 is welded at the bottom of the cross bar 6, an externally threaded rod 4 is welded at the other end of the downward tube 3, the externally threaded rod 4 passes through the hole 7, and the externally threaded rod 4 is embedded in the locking nut 5. By installing the locking nut 5, the locking nut 5 can be used to fix the externally threaded rod 4 inside the locking nut 5, thereby providing an installation position for the downward tube 3, which is very convenient to use.

[0034] The leg tube 9 is welded to the side of the cross bar 6, and the universal wheel 8 is welded to the bottom of the cross bar 6. By installing the universal wheel 8, the universal wheel 8 can be used to provide a moving effect for the pneumatic lifting table. When the pneumatic lifting table needs to be moved to a suitable position, the universal wheel 8 can be directly used to move it, which is very convenient to use.

[0035] The crossbars 6 are distributed in a symmetrical form, and the universal wheels 8 are distributed in a symmetrical form. The distribution form in which the universal wheels 8 are installed can provide stability when the pneumatic lifting table is moved, and the stability is relatively strong during use.

[0036] Working principle of the pneumatic lifting table: When using the pneumatic lifting table, the external threaded rod 4 at one end of the lower slide tube 3 should first be passed through the hole 7 of the cross bar 6, and rotated to install into the locking nut 5, and the lower slide tube 3 should be fixed on the cross bar 6, and then the table top 1 should be placed on the upper fixing plate 16, and the table top 1 should be fixed to the top of the upper fixing plate 16 with bolts, and then the pneumatic lifting table can be used. When it is necessary to lift the pneumatic lifting table up and down, the unlocking wrench 10 can be directly pressed by hand, and it can rotate under the drive of the rotating shaft 17, and then the gas spring lifting switch 11 is driven to control the spring telescopic rod 13 The up and down telescopic adjustment drives the table top 1 to move up and down, which changes the traditional rope control. It has high strength when in use and is not easy to be damaged. At this time, during the extension and retraction process of the upper sliding tube 2 and the lower sliding tube 3, the anti-rotation ring 15 can be used to prevent them from rotating, thereby improving the stability of the table top 1. After adjusting to the appropriate height, release the unlocking wrench 10. When the pneumatic lifting table needs to be moved to the appropriate position, the universal wheel 8 can be used to move it directly. After moving to the appropriate position, the brake device of the universal wheel 8 can be used to start the lifting table and fix it in this position. It is very convenient to use.
