[0026] The following is combined with Figure 1-5 This application is described in further detail.

[0027] The present application embodiment discloses a lifting table. Figure 1 and Figure 2 The lifting table includes a lifting table leg 1 and a table top 2. The table top 2 is installed on the top of the lifting table leg 1, and the table top 2 can adjust the distance between itself and the ground through the lifting table leg 1. An extension plate 3 is detachably installed at the bottom of the table top 2. After the extension plate 3 is removed from the bottom of the table top 2, it can be assembled on one side of the table top 2 to increase the area of ​​the table top 2. In addition, the table top 2 is slidably connected to the lifting table leg 1, so that the length of one side of the table top 2 hanging out of the lifting table leg 1 is longer, so that the lifting table can be transformed into a lifting side table for use.

[0028] Reference Figure 1 and Figure 3The lifting table leg 1 includes a fixed table leg shell and a sliding table leg. The sliding table leg is inserted into the fixed table leg shell and slides along the vertical direction. The fixed table leg shell is installed with a lifting gas pressure rod for driving the sliding table leg to lift. A supporting top plate 11 is welded on the top of the sliding table leg. The size of the supporting top plate 11 is larger than that of the sliding table leg, thereby increasing the contact area between the sliding table leg and the table board 2 and improving the stability of the table board 2 when supporting. The table board 2 is installed on the top of the supporting top plate 11, and a manual switch that can control the operation of the lifting gas pressure rod is provided at the bottom of the table board 2.

[0029] Reference Figure 1 The lifting principle of the lifting table leg 1 is consistent with that of the lifting office chair. When the table board 2 needs to be raised, the manual switch is turned without applying downward pressure to the table board 2, and the lifting cylinder will drive the table board 2 to rise. When the table board 2 needs to be lowered, the manual switch is turned and a downward pressure is applied to the table board 2 to control the table board 2 to descend to any height.

[0030] Reference Figure 2 and Figure 3 The extension plate 3 is located on one side of the support top plate 11, a dovetail bar 21 is integrally formed at the bottom of the table board 2, and a dovetail groove 31 is provided on one surface of the extension plate 3 for the dovetail bar 21 to slide and insert, so that the extension plate 3 can be hung on the bottom of the table board 2 for storage. When the extension plate 3 is stored at the bottom of the table board 2, the surrounding sides of the extension plate 3 do not protrude from the table board 2, so that it can be completely hidden at the bottom of the table board 2 without interfering with items outside the table board 2.

[0031] The outer side wall on one side of the table top 2 in the horizontal direction is provided with a plug-in slot 22, and the side wall of the extension plate 3 on the side where the dovetail slot 31 is vertically provided is integrally formed with a plug-in strip 32 that is slidably inserted into the plug-in slot 22. When the area of ​​the table top 2 needs to be increased, the extension plate 3 is removed from the bottom of the table top 2, and then the plug-in strip 32 is inserted into the plug-in slot 22. After the extension plate 3 is inserted into the plug-in slot 22 through the plug-in strip 32, the side of the extension plate 3 that is away from the dovetail slot 31 is flush with the top surface of the table top 2.

[0032] Reference Figure 2 and Figure 3 , the plug-in slot 22 penetrates the table board 2 on one side along its opening direction; the other side does not penetrate the table board 2, thereby making it difficult for the extension board 3 to be detached from the table board 2 along its own sliding installation direction. In addition, after the plug-in strip 32 is fully inserted into the plug-in slot 22, the two sides of the extension board 3 along its own insertion direction are flush with the two sides of the plug-in slot 22 perpendicularly opened on the table board 2. In this embodiment, the plug-in strip 32 is preferably a T-shaped strip, and the corresponding plug-in slot 22 is a T-shaped slot. This arrangement makes it difficult for the extension board 3 to be pulled off from the table board 2 along the direction perpendicular to its own sliding installation, thereby improving the stability of the extension board 3 after installation.

[0033] The bottom of the table top 2 is also equipped with a sliding guide bar 23 by bolts. The sliding guide bar 23 is located on the side of the supporting top plate 11 away from the extension plate 3, and the other end of the sliding guide bar 23 extends to the side away from the extension plate 3. Two sliding guide bars 23 are arranged at intervals along the direction perpendicular to their own extension direction. The supporting top plate 11 is slidably installed on the two sliding guide bars 23, so that the entire lifting table leg 1 can achieve a sliding connection with the table top 2.

[0034] Reference Figure 3 and Figure 4 The middle part of the sliding guide bar 23 in the width direction is bent toward the direction close to the supporting top plate 11 to form a lower groove 231, and the lower groove 231 extends along the extension direction of the sliding guide bar 23. A waist-shaped adjustment hole 232 is also provided at the bottom of the lower groove 231, and the extension direction of the waist-shaped adjustment hole 232 is consistent with the extension direction of the sliding guide bar. A fastening bolt 24 is inserted into the waist-shaped adjustment hole 232, and the nut head of the fastening bolt 24 is located in the lower groove 231 and does not protrude from the lower groove 231 to interfere with the bottom of the table board 2; the threaded end of the fastening bolt 24 away from its own nut head passes through the waist-shaped hole and is located below the sliding guide bar 23. The support top plate 11 is provided with a bolt hole for the threaded end of the fastening bolt 24 to pass through. The threaded end of the fastening bolt 24 passes through the bolt hole and protrudes out of the support top plate 11 and is located below the support top plate 11. A hand nut 25 is threadedly installed on the fastening bolt 24. The hand nut 25 is located at the bottom of the support top plate 11. Then, tightening the hand nut 25 can limit the support bottom plate 12 on the table top 2. When the lifting table is converted into a side table, the hand nut 25 can be loosened and the table top 2 can be moved.

[0035] Reference Figure 1 and Figure 5 Since the table top 2 overhangs the lift table legs 1 for a long time after the lift table is changed into a side table, it is easy to fall over. Therefore, a bottom plate 12 is welded at the bottom of the fixed table leg shell, and a telescopic plate 13 is slidably installed on the bottom plate 12. The telescopic plate 13 can increase the contact area between the lift table legs 1 and the ground, thereby improving the stability of the table top 2 in the side table state.

[0036] The sliding direction of the telescopic plate 13 is consistent with the extension direction of the sliding guide strip. A telescopic groove 121 is provided on the side wall of the bottom plate 12 parallel to the plug-in groove 22 of the table top 2, and the telescopic plate 13 slides in the telescopic groove 121. When the lifting table is in a normal state, the telescopic plate 13 is stored in the telescopic groove 121; when the lifting table is changed into a side table, the telescopic plate 13 can be pulled out of the telescopic groove 121.

[0037] Reference Figure 1 and Figure 5When the lifting table is in a normal state, the side of the telescopic plate 13 away from the bottom of the telescopic slot 121 protrudes from the telescopic slot 121 and is exposed to the outside. The bottom of the telescopic plate 13 protruding from the telescopic slot 121 is glued with a pad 14, and the side of the pad 14 close to the ground is flush with the side of the bottom plate 12 close to the ground, so that the telescopic plate 13 is not easy to shake due to the height problem between the ground and the telescopic plate 13 after being pulled out.

[0038] A set bolt 15 is threadedly mounted on the outer wall of one side of the bottom plate 12 vertically provided with the telescopic slot 121, and the nut head of the set bolt 15 is exposed outside the bottom plate 12, and the threaded end of the set bolt 15 passes through the bottom plate 12 and is inserted into the telescopic slot 121 and pressed against the side wall of the telescopic plate 13. When the movement of the telescopic plate 13 needs to be limited, the set bolt 15 is screwed so that the set bolt 15 presses the telescopic plate 13 against the slot wall of the telescopic slot 121.

[0039] The implementation principle of a lifting table in the embodiment of the present application is as follows: Under normal circumstances, the extension plate 3 is placed at the bottom of the table top 2 through the cooperation of the dovetail strip 21 and the dovetail groove 31. If the area of ​​the table top 2 needs to be increased, the extension plate 3 is pulled out from the bottom of the table top 2, and then the plug-in strip 32 is inserted into the plug-in groove 22, and the two sides of the extension plate 3 inserted along itself are flush with the two sides of the plug-in groove 22 vertically opened on the table top 2.

[0040] When the lifting table needs to be turned into a side table and placed on one side of the bed, loosen the hand nut 25 and then drive the lifting table leg 1 to move to one side of the table board 2 under the action of the guide rail, so that the table board 2 protrudes longer from the lifting table leg 1, and then tighten the hand nut 25. At the same time, loosen the fixing bolt 15 to pull the telescopic plate 13 out of the telescopic slot 121, and the extension direction of the telescopic plate 13 is consistent with the moving direction of the table board 2, so that the lifting table can be better supported and not easy to tip over.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
