Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary devices, and particularly relates to a folding crutch structure. Background Art

[0002] At present, there are various types of crutches on the market. However, because folding crutches have great portability (height adjustable, easy to carry and store after use) and versatility (usable by people of all heights), folding crutches are popular among most people. For example, the utility model with the application number CN201420873448.X provides a safe folding crutch. By setting an elastic rope and a telescopic nail, when the folding crutch is unfolded and used, the connection between each crutch tube is reliable and safe, playing a dual protection role, and the safety performance is at least doubled. However, the folding of the crutch is at the rod part, and the handle cannot be folded relative to the rod part. Even if the rod part is folded, the handle and the rod part are still in a "T" shape, still occupying a relatively large space and being inconvenient for storage. Content of the Utility Model

[0003] Based on the above problems in the prior art, the utility model provides a folding crutch structure, which includes a rod part and a hand-held part installed at the upper end of the rod part. The hand-held part includes a handle and a clamping part rotatably installed on the handle up and down. The clamping part includes a first clamping arm and a second clamping arm. Arc-shaped clamping grooves are provided on both the first clamping arm and the second clamping arm. The first clamping arm and the second clamping arm are horizontally rotatably connected to each other, and the arc-shaped clamping grooves of the two are symmetrically matched to form a complete clamping groove. A connecting rod for connecting the rod part is clamped and fixed in the complete clamping groove.

[0004] Among them, one end of the handle close to the clamping part is relatively thick and is provided with a first rotating cavity. The clamping part is rotatably installed in the first rotating cavity up and down. When the handle rotates to the horizontal position, the lower part of the end of the handle close to the clamping part abuts against the connecting rod, and a limiting support part protrudes outward at the contact position between the handle and the connecting rod.

[0005] Among them, the first clamping arm includes an integrally formed rotating seat part and a clamping part. A horizontal shaft hole for connecting with the handle is provided at one end of the rotating seat part far from the clamping part. A second rotating cavity is provided on the side of the horizontal shaft hole of the rotating seat part close to the clamping part. The second clamping arm includes a clamping part, and one end of the clamping part is horizontally rotatably installed in the second rotating cavity. The arc-shaped clamping grooves of the first clamping arm and the second clamping arm are both provided on the clamping part, and a bolt fixing part is provided at the other end of the clamping part relative to the rotating seat part.

[0006] Among them, a polygonal nut groove for fitting and embedding with a nut is provided on the bolt fixing part of the second clamping arm. The nut is fixed in the nut groove and will not rotate relative to the second clamping arm. When installing, there is no need to clamp and fix the nut, making the installation more convenient.

[0007] Among them, reinforcing ribs are provided on the surfaces of the clamping parts of the first clamping arm and the second clamping arm that face away from each other. The provision of the reinforcing ribs improves the structural strength of the two clamping walls. When the handle rotates to the horizontal position, the reinforcing ribs are in clearance fit with the end of the handle.

[0008] Among them, arc-shaped clamping ribs are provided on the surfaces of the clamping parts of the first clamping arm and the second clamping arm that face each other. The extending direction of the clamping ribs is perpendicular to the extending direction of the connecting rod.

[0009] Among them, the number of clamping ribs provided on the side of the first clamping arm and the second clamping arm close to the bolt fixing part is less than the number of clamping ribs provided on the side close to the swivel part, so that the side of the first clamping arm and the second clamping arm close to the bolt fixing part has better elastic deformation ability, improving the clamping stability of the connecting rod.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. A clamping part that can rotate up and down relative to the handle is provided. Then, the connecting rod of the mounting rod part or the connecting rod part is clamped by the clamping part, realizing the rotary folding of the handle relative to the rod part, providing an additional folding method for the folding crutch and better meeting different storage requirements.

[0012] 2. Reinforcing structures such as a limit support part, reinforcing ribs, and clamping ribs are provided, which can not only improve the structural strength of the hand-held part but also improve the stability of the fixed clamping of the connecting rod, being beneficial to improving the safety of the crutch.

[0020] The following is a detailed description of the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0021] As shown in the attached Figures 1-7 A folding crutch structure, which includes a conventional crutch part (not shown in the figure) and a handgrip part installed at the upper end of the crutch part. The handgrip part includes a handle 1 and a clamping part 2 rotatably installed on the handle 1 up and down. One end of the handle 1 away from the clamping part 2 is relatively thin and the upper surface of the end is upturned. One end close to the clamping part 2 is relatively thick and is provided with a first rotating cavity 3. The clamping part 2 is rotatably installed in the first rotating cavity 3 by a rotating shaft penetrating through the two side walls of the first rotating cavity 3. When the handle 1 rotates to the horizontal position, the lower part of the end of the handle 1 close to the clamping part 2 abuts against the connecting rod 13, and a limiting support part 4 protrudes outward at the contact position of the handle 1 and the connecting rod 13. A groove 5 matching the fingers is arranged on the lower surface of the handle 1; the clamping part 2 includes a first clamping arm 6 and a second clamping arm 7. The first clamping arm 6 includes an integrally formed rotating seat part 8 and a clamping part 9. One end of the rotating seat part 8 away from the clamping part 9 is provided with a horizontal shaft hole 10 for connecting with the handle 1. The rotating seat part 8 is provided with a second rotating cavity 11 on the side of the horizontal shaft hole 10 close to the clamping part 9. The second clamping arm 7 includes a clamping part 9 and one end of the clamping part 9 is rotatably installed in the second rotating cavity 11 by a rotating shaft penetrating through the top wall and the bottom wall of the second rotating cavity 11. On the mutually close surfaces of the clamping parts 9 of the first clamping arm 6 and the second clamping arm 7, arc-shaped clamping grooves 12 are arranged, and the arc-shaped clamping grooves 12 of the two cooperate symmetrically to form a complete clamping groove. A connecting rod 13 for connecting the crutch part is clamped and fixed in the complete clamping groove. The clamping part 9 is provided with a bolt fixing part 14 at the other end relative to the rotating seat part 8. The first clamping arm 6 and the second clamping arm 7 are tightened and fixed by bolts simultaneously penetrating through the two bolt fixing parts 14 and clamp the connecting rod 13.

[0022] As a preferred embodiment, a polygonal nut groove 15 matching the nut is arranged on the bolt fixing part 14 of the second clamping arm 7, and the nut is fixedly embedded in the nut groove 15; reinforcing ribs 16 are arranged on the mutually far surfaces of the clamping parts 9 of the first clamping arm 6 and the second clamping arm 7. When the handle 1 rotates to the horizontal position, the reinforcing ribs 16 are in clearance fit with the end of the handle 1. When an external force is applied, the handle 1 or the clamping part 2 undergoes slight deformation, and the reinforcing ribs 16 and the end of the handle 1 contact and support each other and share the external force, improving the overall structural strength; arc-shaped clamping ribs 17 are arranged on the mutually close surfaces of the clamping parts 9 of the first clamping arm 6 and the second clamping arm 7. The extending direction of the clamping ribs 17 is perpendicular to the extending direction of the connecting rod 13. The number of clamping ribs 17 arranged on the side of the first clamping arm 6 and the second clamping arm 7 close to the bolt fixing part 14 is less than the number of clamping ribs 17 arranged on the side close to the rotating seat part 8.

[0023] When the folding crutch structure provided in this embodiment is in use, a conventional crutch part can be installed through the connecting rod 13 or the crutch part can be directly clamped. As Figure 1 and Figure 2 shown, when the handgrip is rotated downward until it is perpendicular to the connecting rod 13, the handgrip is in a horizontal unfolded state, and the normal crutch support function can be realized; when storage is required, the handgrip can be rotated upward to fold the handgrip, reducing the occupied space and facilitating storage. When necessary, the handgrip can also be folded, so that the crutch can be used as a hand-held crutch to temporarily meet different usage requirements.

[0024] The above-described embodiments merely represent one implementation manner of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications 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 patent of the present utility model shall be subject to the appended claims.
