[0036] The cushion locking mechanism comprises a hollow seat 10 fixedly installed on the cushion walking frame 101 and a movable bolt axially moving and circumferentially rotatably arranged in the hollow seat 10. The hollow seat 10 is fixed on the cushion walking frame 101 by welding, and has an axial hole 13 axially penetrating through the hollow seat 10, and a first radial groove 11 and a second radial groove 12 respectively arranged at different axial positions of the hollow seat 10 and axially extending to the outside of the axial hole 13, the axial length of the second radial groove 12 being smaller than that of the first radial groove 11, the first radial groove 11 being symmetrically provided with two, the second radial groove 12 being symmetrically provided with two, the first radial groove 11 and the second radial groove 12 being in the shape of a circular-bottom U-shaped structure, and the included angle of the first radial groove 11 and the second radial groove 12 in the axial projection of the hollow seat 10 being 90°, as shown in Figure 5

[0037] The movable bolt is a spring bolt, which comprises a bolt rod 21 and a compression spring 22, the bolt rod 21 being radially provided with a limiting rod 23, the compression spring 22 being sleeved on the bolt rod 21 and acting on the bolt rod 21 to make it displace towards the outside of the axial hole 13, the bolt rod 21 being in a stepped shaft structure, the axial hole 13 being provided with a limiting stop ring 14 at the position close to the first radial groove 11, one end of the compression spring 22 abutting against the stepped surface of the bolt rod 21 and the other end abutting against the limiting stop ring 14, the bolt rod 21 being pulled out to overcome the elastic force of the compression spring 22 to make the compression spring 22 compressed and the insertion end of the bolt rod 21 displace towards the inside of the axial hole 13, and then the limiting rod 23 is clamped in the second radial groove 12 to keep the cushion in the unlocked state; and the insertion end of the bolt rod 21 is displaced towards the outside of the axial hole 13 by the return action of the compression spring 22 when the bolt rod 21 is released, and then the limiting rod 23 is clamped in the first radial groove 11 to keep the cushion in the locked state.

[0038] In order to facilitate the operation of the bolt rod 21, an operation head is fixed on the operation end of the bolt rod 21 opposite to the insertion end, the bolt rod 21 is axially displaced in the axial hole 13 by operating the operation head, and then the limiting rod 23 is switched between the first radial groove 11 and the second radial groove 12, the bolt rod 21 being axially displaced and then rotated during the switching of the first radial groove 11 and the second radial groove 12, the bolt rod 21 being circumferentially rotatably arranged in the axial hole 13.

[0039] The slide rail frame 200 is provided with insertion holes 201 spaced thereon and matched with the movable bolt, the movable bolt being inserted in the insertion holes 201 spaced on the slide rail frame 200 when the limiting rod 23 is clamped in the first radial groove 11 to make the cushion 100 in the locked state, and the movable bolt being separated from the insertion holes 201 when the limiting rod 23 is clamped in the second radial groove 12 to make the cushion 100 in the unlocked state. ​

[0040] In this embodiment, the rear end of the support frame 300 and the front end of the slide rail frame 200 are hinged together by a hinge assembly and connected together by a locking assembly. The locking assembly is located on the upper side of the connection between the support frame 300 and the slide rail frame 200, while the hinge assembly is located on the lower side of the connection between the support frame 300 and the slide rail frame 200.

[0041] Specifically: such as Figure 8 As shown, the hinge assembly includes a first hinge component 31 fixedly connected to the rear end of the support frame 300 and a second hinge component 32 fixedly connected to the front end of the slide rail frame 200. The bottom of the first hinge component 31 and the bottom of the second hinge component 32 are hinged together by a hinge shaft 33. In the unfolded state, the opposing surfaces of the first hinge component 31 and the second hinge component 32 are in contact. During the folding process, the slide rail frame 200 rotates around the hinge shaft 33 toward the bottom of the support frame 300.

[0042] Specifically: such as Figures 6-7 As shown, the locking assembly includes a first locking seat 41 fixedly mounted on the upper surface of the rear end of the support frame 300 and a second locking seat 42 fixedly mounted on the upper surface of the front end of the slide rail frame 200. The first locking seat 41 has a horizontally extending locking rod 410. The second locking seat 42 is rotatably connected to a locking tongue 43 via a pivot shaft 420. A torsion spring 44 is sleeved on the pivot shaft 420. One end of the torsion spring 44 abuts against the second locking seat 42 and the other end abuts against the locking tongue 43, so that the front end of the locking tongue 43 engages with the locking rod 410 around the pivot shaft 420. The front end of the locking tongue 43 has a locking groove that engages with the locking rod 410. In the unfolded state, the locking tongue 43 is held engaged with the locking rod 410 by the action of the torsion spring 44. When it is to be folded, pressing the locking tongue 43 overcomes the torsion spring 44, causing the locking tongue 43 to disengage from the locking rod 410. At this time, the slide rail frame 200 can rotate and fold around the hinge shaft 33.

[0043] To maintain stability in the folded state, this embodiment provides a retaining mechanism at the position where the slide rail 200 and the support frame 300 mate in the folded state. Specifically: a rear support leg 202 is connected to the rear side of the slide rail 200, and a hanging hole 203 is provided at the bottom of the rear support leg 202. The hanging hole 203 is formed by a U-shaped component and the rear support leg 202; a front support leg 301 is connected to the front side of the support frame 300, and a spring hook 302 is provided at the position of the front support leg 301 corresponding to the hanging hole 203. The spring hook 302 and the hanging hole 203 together form the retaining mechanism. During the folding process, the spring hook 302 is pressed and then springs back to hook into the hanging hole 203.

[0044] As an example of elastic hook 302, such as Figures 12-13As shown, the front support leg 301 is provided with a receiving cavity at a position corresponding to the elastic hook 302, the elastic hook 302 comprises a hook body 3021 and a U-shaped spring steel sheet 3022 in the receiving cavity, the upper end of the hook body 3021 is rotatably arranged in the receiving cavity of the front support leg 301 through a rotating shaft, one side of the U-shaped spring steel sheet 3022 is fixedly combined on the hook body 3021 and the other side is abutted against the wall surface of the receiving cavity of the front support leg 301, so that the hook body 3021 has a compression avoidance function after being compressed by an external force, for example, the U-shaped component, and then the hook body 3021 is automatically returned to the original position by the resilience of the U-shaped spring steel sheet 3022 after the U-shaped component passes, so that the elastic hook 302 is hung and matched with the hanging hole 203, and only when the elastic hook 302 is directly compressed to be retracted into the receiving cavity, the slide rail frame 200 can be unfolded in the reverse direction, so that the safety and stability are high.

[0045] The front support leg 301 is provided with a limiting block 3023 at a position above the hook body 3021, and the limiting block 3023 is used to limit the rotating angle of the hook body 3021 outwardly around the rotating shaft.

[0046] The support frame 300 and the slide rail frame 200 of the embodiment are folded to the position and integrally present an inverted V shape, so that they can be placed in a standing state and the floor space is reduced. The upper part of the support frame 300 is provided with a supporting block 303, and the supporting block 303 and the front support leg 301 support the ground in the folded standing state, as shown. Figure 9 In addition, the bottom front side of the front support leg 301 is connected with a walking wheel 304, so that the support frame 300 can be inclined and moved by using the walking wheel 304 in the folded state, which is labor-saving and convenient, and the moving process is kept in a stable folded state under the cooperation of the elastic hook 302 and the hanging hole 203.
