[0047] Please refer to Figures 1 to 8 , to better understand the lift table leg mechanism 10 of the present disclosure, the lift table leg mechanism 10 will be further explained as follows:

[0048] The lifting table leg mechanism 10 of an embodiment includes a telescopic component 100, a fixing component 200, and a rubber sleeve 300. The telescopic component 100 includes a telescopic rod 110 and a telescopic sleeve 120. One end of the telescopic sleeve 120 is fixedly connected to the lifting table main body. The telescopic rod 110 is arranged inside the telescopic sleeve 120. One end of the telescopic rod 110 is fixedly connected to the power output end of the drive motor 700 on the lifting table main body 600. The other end of the telescopic rod 110 is provided with a screwing hole 111. The fixing component 200 includes a threaded fixing rod 210 and a fixing sleeve 220. One end of the threaded fixing rod 210 is movably screwed into the screwing hole 111. The other end of the threaded fixing rod 210 is fixedly connected to the base 500. The other end of the fixing sleeve 220 is fixedly connected to the base 500. The outer peripheral wall of the rubber sleeve 300 is clamped with the inner peripheral wall of the fixing sleeve 220. The inner peripheral wall of the rubber sleeve 300 is sleeved on the telescopic sleeve 120, so that the rubber sleeve 300 is slidably connected to the telescopic sleeve 120.

[0049] In this embodiment, by setting the outer peripheral wall of the rubber sleeve 300 to be clamped with the inner peripheral wall of the fixing sleeve 220, and the inner peripheral wall of the rubber sleeve 300 is sleeved on the telescopic sleeve 120, a gap can be formed between the rubber sleeve 300 at the connection between the fixing sleeve 220 and the telescopic sleeve 120, so that a certain damping can be provided at the connection between the fixing sleeve 220 and the telescopic sleeve 120. When adjusting the relative connection position between the fixing sleeve 220 and the telescopic sleeve 120, a certain external force needs to be applied to make the fixing sleeve 220 and the telescopic sleeve 120 move relative to each other. Thereby, the connection stability between the fixing sleeve 220 and the telescopic sleeve 120 can be effectively enhanced, avoiding loosening or displacement during the use of the lifting table leg mechanism 10, and ensuring the connection stability between the fixing sleeve 220 and the telescopic sleeve 120 when the lifting table 20 is lifted or lowered.

[0050] It can be understood that the rubber sleeve 300 can also play a protective role in the connection between the fixing sleeve 220 and the telescopic sleeve 120, avoiding the direct connection between the fixing sleeve 220 and the telescopic sleeve 120, effectively reducing the friction force between the fixing sleeve 220 and the telescopic sleeve 120, thereby reducing the maintenance frequency of the fixing sleeve 220 and the telescopic sleeve 120, and further effectively extending the service life of the fixing sleeve 220 and the telescopic sleeve 120.

[0051] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 7As shown, in one embodiment, the number of telescopic components 100 is two groups, namely the first telescopic component 100a and the second telescopic component 100b. The first telescopic component 100a includes a first telescopic rod 110a and a first telescopic sleeve 120a. One end of the first telescopic sleeve 120a is fixedly connected to the main body of the lifting table. The first telescopic rod 110a is disposed within the first telescopic sleeve 120a. One end of the first telescopic rod 110a is fixedly connected to the power output end of the drive motor on the main body of the lifting table. The other end of the first telescopic rod 110a is provided with a first threaded hole 111a. The second telescopic component 100b includes a second telescopic rod 110b and a second telescopic sleeve 120b. One end of the second telescopic sleeve 120b is movably connected to the other end of the first telescopic sleeve 120a. The other end of the second telescopic sleeve 120b is movably connected to the fixed sleeve 220. The second telescopic rod 110b is disposed within the second telescopic sleeve 120b. One end of the second telescopic rod 110b is movably screwed to the first threaded hole 111a. The other end of the second telescopic rod 110b is provided with a second threaded hole 111b. One end of the threaded fixing rod 210 is movably screwed to the second threaded hole 111b.

[0052] It can be understood that one end of the first telescopic rod 110a is fixedly connected to the power output end of the drive motor on the main body of the lifting table. The other end of the first telescopic rod 110a is provided with a first threaded hole 111a. One end of the second telescopic rod 110b is movably screwed to the first threaded hole 111a. The other end of the second telescopic rod 110b is provided with a second threaded hole 111b. One end of the threaded fixing rod 210 is movably screwed to the second threaded hole 111b. When the drive motor operates, the power output end of the drive motor drives the first telescopic rod 110a to rotate. The first telescopic rod 110a drives the second telescopic rod 110b to rotate. The second telescopic rod 110b drives the threaded fixing rod 210 to rotate, thereby realizing the lifting of the main body 600 of the lifting table. Further, setting the number of telescopic components 100 to two groups can effectively increase the height adjustment range of the liftable table leg mechanism 10, thereby effectively improving the practicality of the lifting table 20.

[0053] Such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, in one embodiment, the number of glue kits 300 is two, namely the first glue kit 300a and the second glue kit 300b. A number of first protrusions 310a are provided on the outer peripheral wall of the first glue kit 300a, and a number of first clamping grooves 1201b are formed on the inner peripheral wall of one end of the second telescopic tube sleeve 120b. Each first protrusion 310a is clamped in the corresponding first clamping groove 1201b, and the inner peripheral wall of the first glue kit 300a is sleeved on the first telescopic tube sleeve 120a, so that the first glue kit 300a is slidably connected to the first telescopic tube sleeve 120a. A number of second protrusions 310b are provided on the outer peripheral wall of the second glue kit 300b, and a number of second clamping grooves 221 are formed on the inner peripheral wall of one end of the fixed tube sleeve 220. Each second protrusion 310b is clamped in the corresponding second clamping groove 221, and the inner peripheral wall of the second glue kit 300b is sleeved on the second telescopic tube sleeve 120b, so that the second glue kit 300b is slidably connected to the second telescopic tube sleeve 120b.

[0054] It can be understood that by clamping each first protrusion 310a in the corresponding first clamping groove 1201b, the outer peripheral wall of the first glue kit 300a is clamped to the second telescopic tube sleeve 120b. Also, since the inner peripheral wall of the first glue kit 300a is sleeved on the first telescopic tube sleeve 120a, the first glue kit 300a can fill the gap at the connection between the first telescopic tube sleeve 120a and the second telescopic tube sleeve 120b, thereby effectively enhancing the connection strength between the first telescopic tube sleeve 120a and the second telescopic tube sleeve 120b.

[0055] Similarly, by clamping each second protrusion 310b in the corresponding second clamping groove 221, the outer peripheral wall of the second glue kit 300b is clamped to the fixed tube sleeve 220. Also, since the inner peripheral wall of the second glue kit 300b is sleeved on the second telescopic tube sleeve 120b, the second glue kit 300b can fill the gap at the connection between the second telescopic tube sleeve 120b and the fixed tube sleeve 220, thereby effectively enhancing the connection strength between the second telescopic tube sleeve 120b and the fixed tube sleeve 220.

[0056] By providing the first glue kit 300a and the second glue kit 300b, the connection strength between the first telescopic tube sleeve 120a and the second telescopic tube sleeve 120b is effectively enhanced, and the connection strength between the second telescopic tube sleeve 120b and the fixed tube sleeve 220 is effectively enhanced. Furthermore, the stability of the lifting table leg mechanism 10 during the lifting process is effectively improved.

[0057] Such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, in one embodiment, the lifting leg mechanism 10 further includes a connection assembly 400, and the connection assembly 400 includes a first connection member 410 and a second connection member 420. The first connection member 410 is fixedly connected to the inner peripheral wall of the other end of the first telescopic sleeve 120a. The first connection member 410 is provided with a first threaded hole 4101, and one end of the second telescopic rod 110b is screwed into the first threaded hole 4101. The second connection member 420 is fixedly connected to the inner peripheral wall of the other end of the second telescopic sleeve 120b. The second connection member 420 is provided with a second threaded hole 4201, and one end of the threaded fixing rod 210 is screwed into the second threaded hole 4201.

[0058] It can be understood that by fixedly connecting the first connection member 410 to the inner peripheral wall of the other end of the first telescopic sleeve 120a and screwing the first connection member 410 with the second telescopic rod 110b, the connection stability between the first telescopic sleeve 120a and the second telescopic rod 110b can be effectively enhanced, preventing the first telescopic sleeve 120a and the second telescopic rod 110b from shaking during the lifting process.

[0059] Similarly, the second connection member 420 is fixedly connected to the inner peripheral wall of the other end of the second telescopic sleeve 120b, and the second connection member 420 is screwed with one end of the threaded fixing rod 210, which can effectively enhance the connection stability between the second telescopic sleeve 120b and the threaded fixing rod 210, preventing the first telescopic sleeve 120a and the second telescopic rod 110b from shaking during the lifting process. Further, by providing the first connection member 410 and the second connection member 420, the overall lifting leg mechanism 10 has better structural stability, so that it can operate more stably during the lifting process.

[0060] As Figure 7 and Figure 8 shown, in one embodiment, the connection assembly further includes a first elastic member 430, a second elastic member 440, a plurality of first fixing members 450 and a plurality of second fixing members 460;

[0061] The first connection member is provided with a first installation groove 4102 and a plurality of first installation holes 4103. The first elastic member 430 is disposed in the first installation groove 4102. Two ends of the first elastic member 430 respectively abut against the corresponding first fixing members 450. A plurality of first through holes are formed in the inner peripheral wall of the other end of the first telescopic rod. One end of each first fixing member 450 is disposed in the corresponding first installation hole 4103, and the other end of each first fixing member 450 passes through the corresponding first through hole;

[0062] The second connecting member is provided with a second installation groove 4202 and a plurality of second installation holes 4203. The second elastic member 440 is disposed in the second installation groove 4202. Two ends of the second elastic member 440 respectively abut against corresponding second fixing members 460. A plurality of second passing holes are formed in the inner peripheral wall of the other end of the second telescopic rod. One end of each second fixing member 460 is disposed in the corresponding second installation hole 4203, and the other end of each second fixing member 460 passes through the corresponding second passing hole.

[0063] It can be understood that during the lifting and use of the lifting table, the first elastic member 430 and the second elastic member 440 will undergo elastic deformation and absorb part of the energy. This elastic deformation can relieve the direct impact of the external force on the telescopic rod 110, thereby reducing the vibration and noise generated by the lifting table leg mechanism 10.

[0064] One end of the fixing member is disposed in the first installation hole 4103, and the other end passes through the first passing hole 1102a to ensure that the connecting member will not be damaged or fail when bearing the load. By arranging the fixing member to pass through the connecting member and the telescopic member respectively, the connecting member and the telescopic member are fixedly connected. At the same time, the connecting member is sleeved on the transmission rod, and the telescopic member and the transmission rod form an integral body through the connecting member, so that the lifting table 20 has better structural stability and is more stable during the lifting process of the lifting table 20.

[0065] As Figure 5 and Figure 6 shown, in one embodiment, the first elastic member 430 and the second elastic member 440 are stainless steel springs. It can be understood that the stainless steel spring has good corrosion resistance, so that the first elastic member 430 and the second elastic member 440 are not easily rusted or damaged, thereby extending the service life of the first elastic member 430 and the second elastic member 440. And the stainless steel spring has good elasticity and can deform after being squeezed by the first fixing member 450 and the second fixing member 460, and return to its original state when the squeezing force disappears, maintaining stable elastic characteristics.

[0066] As Figure 2 , Figure 3 and Figure 6 shown, in one embodiment, the first fixing member 450 and the second fixing member 460 are rubber pins. It can be understood that the rubber pin has good resilience performance, which can provide good shock absorption and buffering effects for the first telescopic tube sleeve 120a and the second telescopic tube sleeve 120b, reducing the vibration transmission and noise generation during the lifting of the lifting table. At the same time, the rubber pin has good wear resistance and can maintain good use performance for a long time, so that the service life of the first fixing member 450 and the second fixing member 460 can be effectively extended.

[0067] As Figure 1 ,Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in Figure 4 and Figure 5 , in one embodiment, a plurality of adjusting disks 510 are provided on the base 500, and each adjusting disk 510 is detachably connected to the base 500. It should be noted that in this embodiment, the base 500 and the adjusting disk 510 are locked and fixed by a plurality of bolt members 520. The adjusting disk 510 is an arc-shaped arched disk with strong gripping force, thereby effectively improving the stability of the lifting table leg mechanism 10 and the lifting table. By setting the adjusting disk 510 and the base 500 to be detachably connected, the adjusting disk 510 and the base 500 can be disassembled and assembled, facilitating the inspection and maintenance of the base 500 and the adjusting disk 510, and thus effectively improving the inspection efficiency of the lifting table leg mechanism 10.

[0068] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , in one embodiment, each adjusting disk 510 is provided with a screwing portion 5110, and the base 500 is provided with a plurality of third screwing holes 501. Each screwing portion 5110 is screwed with a corresponding third screwing hole 501. It can be understood that by providing a screwing portion 5110 on each adjusting disk 510 and the base 500 being provided with a plurality of third screwing holes 501, and each screwing portion 5110 being screwed with a corresponding third screwing hole 501, the adjusting disk 510 can be fixed on the base 500, and the fixing method by screwing with the screwing portion 5110 makes the disassembly and repair of the adjusting disk 510 easier, and at the same time makes the connection between the adjusting disk 510 and the base 500 more stable.

[0069] The present disclosure also provides a lifting table 20, including a lifting table main body 600, a driving motor 700, and a plurality of lifting table leg mechanisms 10 in any one of the above embodiments.

[0070] In this embodiment, by setting the outer peripheral wall of the rubber sleeve 300 to be clamped with the inner peripheral wall of the fixed pipe sleeve 220, and the inner peripheral wall of the rubber sleeve 300 being sleeved on the telescopic pipe sleeve 120, the gap at the connection between the fixed pipe sleeve 220 and the telescopic pipe sleeve 120 can be filled by the rubber sleeve 300, thereby effectively enhancing the connection stability between the fixed pipe sleeve 220 and the telescopic pipe sleeve 120, preventing the lifting table 20 from loosening or shifting during use, and thus effectively improving the stability of the lifting table 20 during lifting.

[0071] Compared with the prior art, the present utility model has at least the following advantages:

[0072] By setting the outer peripheral wall of the rubber kit to be clamped with the inner peripheral wall of the fixed pipe sleeve, and the inner peripheral wall of the rubber kit is sleeved on the telescopic pipe sleeve, the gap at the connection between the fixed pipe sleeve and the telescopic pipe sleeve can be filled by the rubber kit, so as to effectively enhance the connection stability between the fixed pipe sleeve and the telescopic pipe sleeve, avoid loosening or displacement during the use of the lifting table leg mechanism, and ensure the connection stability between the fixed pipe sleeve and the telescopic pipe sleeve when the lifting table is lifted or lowered.

[0073] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
