Example

[0023] See also Figure 1-11A lifting table leg fixing structure includes a lifting table leg 1 and a supporting pad 2. The supporting pad 2 is provided with a connecting hole 21 for inserting the lower end of the lifting table leg 1. The lifting table leg 1 is provided with a clamping hole 12. A clamping piece 3 is provided in the supporting pad 2. The clamping piece 3 includes a movable clamping part and an elastic reset part. The clamping part moves under the insertion action of the lifting table leg 1, and is clamped with the clamping hole 12 on the lifting table leg 1 through the elastic reset part. A plurality of clamping pieces 4 are provided on the supporting pad 2. The lifting table leg 1 is provided with a plurality of slots 111 for the clamping pieces 4 to be inserted to form clamping. When the lifting table leg 1 is inserted into the connecting hole 21, the plurality of clamping pieces 4 form inner and outer clamping on multiple corners of the lifting table leg 1, and cooperate with the clamping piece 3 to realize screwless fixation of the lifting table leg 1.

[0024] The clamping member 3 further comprises a mounting shell 31 , and the clamping portion comprises a moving block 32 , which is movably disposed in the mounting shell 31 , and a clamping end 321 adapted to the clamping hole 12 is disposed on the moving block 32 .

[0025] The elastic reset member is a spring 33 when in use. A mounting groove 323 is provided on the moving block 32. One end of the spring 33 is arranged in the mounting groove 323, and the other end thereof contacts the side wall of the mounting shell 31. The spring 33 provides automatic reset elastic force for the moving block 32, so that the clamping end 321 can be quickly clamped into the clamping hole 12 when the lifting table leg 1 is inserted, thereby realizing automatic clamping. The mounting groove 323 on the moving block 32 accurately positions the spring 33 to prevent the spring 33 from deflecting, thereby ensuring stable transmission of the elastic force and enhancing the reliability of the clamping.

[0026] The clamping member 4 includes a main body block 41, on which a clamping end 42 and a clamping plate 43 are provided. A clamping groove for inserting the lift table leg 1 is formed between the clamping end 42 and the clamping plate 43. The clamping member 4 constructs a clamping groove through the main body block 41, the clamping end 42, and the clamping plate 43 to provide guidance and initial limit for the insertion of the lift table leg 1. The clamping end 42 and the clamping plate 43 act from the inside and outside respectively to form a basic clamping structure, which preliminarily enhances the stability of the table leg fixation.

[0027] There are two clamping plates 43, which are symmetrically distributed on both sides of the clamping end 42. The two clamping plates 43 and the clamping end 42 together form a three-point clamping structure. The two symmetrically distributed clamping plates 43 are subjected to balanced forces. The clamping end 42 and the clamping plates 43 on both sides form a three-point clamping structure, thereby constructing a stable mechanical support system and effectively improving the fixing strength of the connection of the lifting table legs 1.

[0028] A guide end 44 with a sloped structure is provided on the clamping end 42. Both sides of the clamping end 42 extend toward the clamping plate 43 to form a bent end 45. The two clamping ends 42 are arranged at a right angle and are adapted to the inner right-angled corners of the lift table leg 1. The inclined guide end 44 of the clamping end 42 guides the lift table leg 1 to be quickly aligned and inserted, reducing the difficulty of installation. The bent ends 45 arranged at right angles on both sides are adapted to the inner right-angled corners of the table leg to achieve surface contact clamping, increase friction, and enhance clamping stability.

[0029] The mounting shell 31 is composed of an upper shell 311 and a lower shell 312. The lower shell 312 is symmetrically provided with upwardly extending limit plates 3121. A moving groove 3122 for the moving block 32 to slide is formed between the limit plates 3121. The moving block 32 is arranged in the moving groove 3122. The upper and lower shell 312 structures of the mounting shell 31 are convenient for the assembly and maintenance of internal components (such as the moving block 32 and the spring 33). The limit plates 3121 and the moving groove 3122 of the lower shell 312 provide guidance for the moving block 32, constraining it to move in a straight line, ensuring that the clamping end 321 is accurately clamped into the clamping hole 12, thereby improving the clamping reliability.

[0030] A socket 322 is provided on the moving block 32, and the clamping part 3 also includes a control board 34 inserted into the socket 322 to drive the moving block 32 to move. Moving holes 3123 are provided at the bottom of the mounting shell 31 and the bottom of the supporting pad 2. The upper end of the control board 34 passes through the moving hole 3123 and is located in the socket 322 of the moving block 32. Through the moving holes 3123 at the bottom of the mounting shell 31 and the supporting pad 2, a manual control interface is provided for the disassembly operation, so that the user can control the movement of the moving block 32 so that the clamping end 321 can quickly detach from the clamping hole 12 to achieve convenient disassembly.

[0031] The control board 34 is provided with a groove 341 adapted to the spring 33. One end of the spring 33 located in the moving block 32 abuts against the groove 341, and the control board 34 is firmly installed in the socket 322. The groove 341 on the control board 34 abuts against the spring 33 to prevent the control board 34 from falling off in the socket 322, thereby ensuring the stable position of the control board 34.

[0032] A connecting plate 11 is provided at the lower end of the lift table leg 1, and a plurality of slots 111 are opened on the connecting plate 11. The clamping end 42 is inserted into the inner side of the lift table leg 1 through the slot 111 to cooperate with the clamping plate 43 to clamp the lift table leg 1. The upper surface of the connecting plate 11 at the lower end of the lift table leg 1 is flush with the lower side edge of the clamping hole 12. When the lift table leg 1 is inserted into the connecting hole 21 and the clamping is completed, the lower surface of the clamping end 321 of the moving block 32 passes through the clamping hole 12 and contacts the upper surface of the connecting plate 11. The connecting plate 11 can share the pressure of the clamping end 321, reduce the fatigue risk of the material around the clamping hole 12, and extend the service life of the fixed structure of the lift table leg 1.

[0033] When it is necessary to disassemble the lifting table leg 1, the control plate 34 is operated to move the control plate 34 toward the direction of the spring 33, and the control plate 34 drives the moving block 32 to slide in the moving groove 3122 formed by the limit plate 3121, so that the clamping end 321 is moved out of the clamping hole 12, thereby releasing the clamping. At this time, the lifting table leg 1 can be pulled out of the connecting hole 21, and the table leg is quickly disassembled; When installing the lift table leg 1, align the lower end of the lift table leg 1 with the connecting hole 21 on the supporting pad 2 and insert it. During the insertion process, the lift table leg 1 will push the moving block 32 in the clamping piece 3. Since the moving block 32 is provided with a clamping end 321 adapted to the clamping hole 12, and the moving block 32 is connected to the mounting shell 31 through a spring 33, the moving block 32 will compress the spring 33 and move after receiving the thrust of the lift table leg 1. When the clamping end 321 is aligned with the clamping hole 12 on the lift table leg 1, the elastic force of the spring 33 causes the clamping end 321 to be inserted into the clamping hole 12 to achieve clamping. At the same time, the slot 111 on the connecting plate 11 at the lower end of the lift table leg 1 corresponds to the clamping piece 4 on the supporting pad 2. The clamping ends 42 of the multiple clamping members 4 are inserted into the inner side of the lift table leg 1 through the slot 111, and the two clamping plates 43 symmetrically distributed on both sides of the clamping ends 42 are located on the outer side of the lift table leg 1, and together form inner and outer clamping for multiple corners of the lift table leg 1, wherein the guide end 44 on the clamping end 42 has a slope structure, which can guide the lift table leg 1 to be smoothly inserted into the clamping groove, thereby improving the convenience of installation, and the bent ends 45 on both sides of the clamping end 42 are arranged at right angles, which are adapted to the inner right-angle corners of the lift table leg 1, thereby increasing the contact area and further enhancing the stability of the clamping, thereby realizing the quick assembly and disassembly of the lift table leg 1 without screws, and meeting the user's demand for portable disassembly and assembly of the lift table.
