[0002] A chair is one of the essential pieces of furniture in a home office. People spend most of their time sitting on a chair to work during their long rest and relaxation time. Sitting for a long time can easily lead to physical fatigue, and the most direct way to solve fatigue is to lie on a leisure chair and rest.

[0003] Some devices on the market generally connect one end of the connecting rod assembly directly to the bench and the other end of the connecting rod assembly to the footrest. When the driving assembly rotating frame rotates around the hinge point between the driving assembly and the bench to drive the footrest to expand or collapse relative to the bench, the connecting rod assembly can directly drive the footrest to slide relative to the rotating frame.

[0004] However, during actual use of the above-mentioned device, the footrest will support the user's feet when in use. However, the lengths of different people's feet are different, which makes it impossible for the footrest to support the user according to the length of the user's feet. In view of this, we propose a self-resetting chair foot support. Utility Model Content

[0015] Compared with the prior art, the utility model provides a self-resetting seat foot support, which has the following beneficial effects:

[0016] 1. The self-resetting chair foot support, in order to avoid the equipment being unable to be adjusted according to the needs of the user, the electric telescopic rod is extended to make the support plate hinged inside the mounting part move, so that the support plate is unfolded, and then the L-shaped block is pulled to move the L-shaped block upward inside the movable groove, so that the L-shaped block drives the movable block to compress the small spring while the L-shaped block releases the limit on the connecting plate, so that the connecting plate can be unfolded and keep in a straight line with the support plate, and when the L-shaped block is released, the elastic force of the small spring bounces the movable block into the slot, so that the movable block can limit the connecting plate, so that the support plate and the connecting plate can cooperate to provide better support for users with longer legs, and the setting of the electric telescopic rod can well allow the support plate to be self-reset and retracted.

[0017] 2. The self-resetting seat foot support can be used to retract the device when not in use. When the mounting part is not in use, the mounting part can be pushed to allow the fixed block to move inside the through groove, which causes the mounting part to compress the large spring, so that the limit groove corresponds to the mounting groove, and then the movable part is moved to the vertical part of the L-shaped fixed groove, so that the movable part drives the limit block to be stuck in the limit groove, which allows the mounting part to be well retracted when not in use.

A limit block 20 is clamped inside the installation groove 18, and a movable groove 21 is provided on one side of the limit block 20. A movable part 22 is clamped inside the movable groove 21, and the movable part 22 is arranged inside the fixed groove 19. The size of the movable part 22 is adapted to the size of the fixed groove 19. An electric telescopic rod 6 is fixed to one side of the fixing part 5, and a support plate 4 is hinged at one end of the electric telescopic rod 6. An adjusting device is provided at the bottom of the support plate 4, and the adjusting device includes a placement groove 7, a small spring 8, a movable groove 11, a movable block 9, a clamping block 10, a connecting plate 12 and a clamping groove 13.

[0026] In the embodiment of the utility model, a placement groove 7 is provided at the bottom of the support plate 4, and a small spring 8 is fixedly connected to the top of the inner wall of the placement groove 7. A movable groove 11 is provided on the inner wall of the placement groove 7 near the electric telescopic rod 6. One end of the small spring 8 is fixedly connected to a movable block 9, which is arranged inside the placement groove 7. The size of the movable block 9 is adapted to the size of the placement groove 7, which allows the movable block 9 to move well inside the placement groove 7. A clamping block 10 is fixedly connected to one side of the movable block 9, and the clamping block 10 is arranged in an L shape. A connecting plate 12 is hingedly provided at the bottom of the support plate 4.
