Technical Field

[0001] This utility model belongs to the technical field of seat leg disassembly and assembly mechanism, and particularly relates to a seat leg disassembly and assembly mechanism that is easy to replace. Background Technology

[0002] During use, some chair legs may wear out, affecting their performance and requiring replacement. This necessitates a chair leg disassembly and assembly mechanism. However, existing mechanisms often use bolts for fixing, which makes installation and disassembly inconvenient. Furthermore, parts may be lost during transportation, affecting overall installation efficiency. Utility Model Content

[0003] This utility model addresses the problem in the prior art that additional tools and external bolts are required during installation and disassembly, and proposes the following technical solution: A seat mounting and dismounting mechanism for easy replacement includes a pentagonal frame, with legs slidably connected to the outer surface of the pentagonal frame, casters rotatably connected to the bottom end of the legs, auxiliary components fixedly connected to the outer surface of the pentagonal frame, and a limiting component snapped onto the legs.

[0004] As a preferred embodiment of the above technical solution, the auxiliary component includes a locking rod that is slidably connected to the inner surface of the tripod, a sliding clamp that is slidably connected to the inner surface of the locking rod, a slide frame that is slidably connected to the inner surface of the locking rod, a linkage rod that is fixedly connected to the outer end of the slide frame, and the other end of the linkage rod that is fixedly connected to the inner end of the sliding clamp.

[0005] As a preferred embodiment of the above technical solution, an auxiliary threaded rod is rotatably connected to the inner surface of the lever, the outer surface of the auxiliary threaded rod is threadedly connected to the inner surface of the slide, and an auxiliary knob is fixedly connected to the inner end of the auxiliary threaded rod.

[0006] As a preferred embodiment of the above technical solution, the limiting component includes a square frame fixedly connected to the outer surface of the pentagonal frame, a guide rod fixedly connected to the outer end of the square frame, the outer surface of the guide rod being slidably connected to the inner surface of the leg, a return spring rod fixedly connected to the inner surface of the square frame, a side plate fixedly connected to the other end of the return spring rod, the outer surface of the side plate being slidably connected to the inner surface of the square frame, and an inclined locking block provided on the outer surface of the side plate, the outer surface of the inclined locking block engaging with the inner surface of the leg.

[0007] As a preferred embodiment of the above technical solution, a telescopic rod is fixedly connected between the opposite surfaces of the adjacent side plates, and a slanted chuck is slidably connected to the inner surface of the square frame, with the outer inclined surface of the slanted chuck abutting against the inner inclined surface of the side plate.

[0008] As a preferred embodiment of the above technical solution, the inner surfaces of the pentagonal frame and the square frame are rotatably connected to a lateral threaded rod. The outer surface of the lateral threaded rod is threadedly connected to the inner surface of the inclined chuck. A bevel gear one is fixedly connected to one end of the lateral threaded rod near the pentagonal frame. A bevel gear two is meshed with the outer surface of the bevel gear one. The outer surface of the bevel gear two is rotatably connected to the inner surface of the pentagonal frame. The bottom end of the bevel gear two passes through the pentagonal frame and is fixedly connected to a limit knob.

[0009] The beneficial effects of this utility model are as follows: Twisting the limit knob, through the meshing transmission of bevel gear two and bevel gear one, and the threaded transmission of bevel gear one and the slanted chuck, can drive the slanted chuck to move outward from the square frame under the limit. Through the engagement of the slanted chuck with the inclined surface of the side plate, the side plate and slanted block, which have already been limited, are further limited, improving the overall stability. When the slanted chuck moves inward to the pentagonal frame, it can also drive the side plate inward through the engagement of the slanted chuck with the inclined surface of the side plate, thus releasing the limit on the side plate and slanted block, facilitating quick installation and disassembly by the user. At the same time, through the action of the telescopic rod and the connecting rod of the side plate, it can ensure that each side plate moves synchronously, and the force is evenly distributed to each side plate, improving the overall reliability and service life. Attach the locking rod to the tripod, turn the auxiliary knob, and through the threaded connection between the auxiliary threaded rod and the slide, and the locking rod's limiting action on the slide, the slide can be moved to slide. Through the linkage between the sliding clip, the slide, and the linkage rod, and the locking rod's limiting action on the sliding clip, the sliding clip can be engaged with the inner surface of the tripod, ensuring stable force distribution between all parts, facilitating quick installation and replacement, and improving overall practicality.

[0012] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0013] Example 1 This utility model provides a seat foot removal and assembly mechanism that is easy to replace, such as... Figures 1 to 8As shown, the chair includes a pentagonal frame 1 for fixing the external gas spring to the seat surface. Legs 2 are slidably connected to the outer surface of the pentagonal frame 1. Casters 3 are rotatably connected to the bottom of the legs 2. A limiting assembly 5 is engaged on the legs 2. The limiting assembly 5 includes a square frame 501 fixedly connected to the outer surface of the pentagonal frame 1. A guide rod 502 is fixedly connected to the outer end of the square frame 501. The outer surface of the guide rod 502 is slidably connected to the inner surface of the legs 2. A return spring rod 503 is fixedly connected to the inner surface of the square frame 501. A side plate 504 is fixedly connected to the other end of the return spring rod 503. The side plates 504 are evenly distributed around the circumference of the square frame 501 to facilitate the handling of forces generated between the legs 2 and the inclined locking block 505. The outer surface of side plate 504 is slidably connected to the inner surface of square frame 501. An inclined locking block 505 is provided on the outer surface of side plate 504. When square frame 501 and guide rod 502 are inserted into leg 2, the inclined surface of the inclined locking block 505 causes side plate 504 to move inward. Then, the return spring rod 503 causes side plate 504 to return to its original position, completing the limiting engagement between leg 2 and inclined locking block 505. Multiple sets of inclined locking blocks 505 improve the limiting strength and overall stability of leg 2. The outer surface of the inclined locking block 505 mates with the inner surface of leg 2. A telescopic rod 506 is fixedly connected between the opposing surfaces of adjacent side plates 504. An inclined chuck 507 is slidably connected to the inner surface of square frame 501. The outer end of the inclined chuck 507 is inclined... The inner inclined surface of the side plate 504 abuts against the inner end of the pentagonal frame 1 and the square frame 501. A lateral threaded rod 508 is rotatably connected to the inner surface of the lateral threaded rod 508. The outer surface of the lateral threaded rod 508 is threadedly connected to the inner surface of the inclined chuck 507. A bevel gear 509 is fixedly connected to one end of the lateral threaded rod 508 near the pentagonal frame 1. A bevel gear 510 is meshed with the outer surface of the bevel gear 509. The outer surface of the bevel gear 510 is rotatably connected to the inner surface of the pentagonal frame 1. The bottom end of the bevel gear 510 passes through the pentagonal frame 1 and is fixedly connected to a limit knob 511. Turning the limit knob 511, through the meshing transmission between the bevel gear 510 and the bevel gear 509 and the threaded transmission between the bevel gear 509 and the inclined chuck 507, can drive... The movable inclined chuck 507 moves outward from the pentagonal frame 1 under the limiting position of the square frame 501. Through the engagement of the inclined chuck 507 with the inclined surface of the side plate 504, the side plate 504 and the inclined locking block 505, which have already been limited, are further limited, improving the overall stability. When the inclined chuck 507 moves inward from the pentagonal frame 1, it can also drive the side plate 504 to move inward through the engagement of the inclined chuck 507 with the inclined surface of the side plate 504, thereby releasing the limitation position of the side plate 504 and the inclined locking block 505. This facilitates quick installation and disassembly by the user. At the same time, through the linkage between the telescopic rod 506 and the side plate 504, the synchronous movement of each side plate 504 can be ensured, and the force can be evenly distributed to each side plate 504, improving the overall reliability and service life.

[0014] like Figures 1 to 8 As shown, auxiliary components 4 are uniformly fixedly connected to the outer surface of the pentagonal frame 1 for linkage support between the various legs 2. The auxiliary components 4 include a locking rod 401 slidably connected to the inner surface of the legs 2, a sliding clamp 402 slidably connected to the inner surface of the locking rod 401, a slide 403 slidably connected to the inner surface of the locking rod 401, a linkage rod 404 fixedly connected to the outer end of the slide 403, the other end of the linkage rod 404 fixedly connected to the inner end of the sliding clamp 402, and an auxiliary threaded rod 405 rotatably connected to the inner surface of the locking rod 401. The outer surface of the auxiliary threaded rod 405 is connected to the inner surface of the slide 403. The auxiliary threaded rod 405 has an auxiliary knob 406 fixedly connected to its inner end. The locking rod 401 is locked onto the stand 2. By turning the auxiliary knob 406, the slide 403 can be slid through the threaded connection between the auxiliary threaded rod 405 and the slide 403, and the locking rod 401 limits the slide 403. Through the linkage of the sliding locking part 402, the slide 403 and the linkage rod 404, and the locking rod 401 limits the sliding locking part 402, the sliding locking part 402 can be locked onto the inner surface of the stand 2, ensuring the stability of the force between each part, facilitating quick installation and replacement, and improving the overall practicality.

[0015] Working principle: During installation, turning the limit knob 511 activates the bevel gear 2 510, which meshes with the bevel gear 1 509, and the bevel gear 1 509 engages with the slant chuck 507 via a threaded connection. This moves the slant chuck 507 to the center position, aligning the notch on the stand 2 with the limit assembly 5. Guided by the square frame 501 and the guide rod 502, the stand 2 is installed. Turning the limit knob 511 again moves the slant chuck 507 towards the center under the limit of the square frame 501. The outer side of the pentagonal frame 1 moves, and through the engagement of the inclined chuck 507 with the inclined surface of the side plate 504, the side plate 504 and the inclined locking block 505, which have already been limited, are further limited, improving the overall stability. At the same time, through the linkage between the telescopic rod 506 and the side plate 504, the synchronous movement of each side plate 504 can be ensured, and the force can be evenly distributed to each side plate 504, improving the overall reliability and service life. The locking rod 401 is locked onto the leg 2. By turning the auxiliary knob 406, through the threaded connection between the auxiliary threaded rod 405 and the slide 403 and the limitation of the slide 403 by the locking rod 401, the slide 403 can be driven to slide. Through the linkage between the sliding locking part 402, the slide 403 and the linkage rod 404, and the limitation of the sliding locking part 402 by the locking rod 401, the sliding locking part 402 can be driven to lock onto the inner surface of the leg 2, ensuring the stability of the force between each part, facilitating quick installation and replacement, and improving the efficiency. In terms of overall practicality, when disassembly is required, turning the auxiliary knob 406 releases the limiting position of the sliding clip 402 on the clip rod 401, completing the removal of the auxiliary component 4. Turning the limiting knob 511 moves the inclined chuck 507 to the inside of the pentagonal frame 1. The inclined chuck 507 can also cooperate with the inclined surface of the side plate 504 to move the side plate 504 to the inside, completing the release of the limiting position of the side plate 504 and the inclined clip 505, which facilitates quick installation and disassembly by the user.

[0016] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
