Description

a retractable crutch

technical field

The utility model relates to the field of walking aids, in particular to a retractable crutch.

Background technique

The traditional telescopic crutches are all circular cross-sections, which are well stressed. However, during use, the inner and outer tubes can rotate freely along their axial directions, making it difficult for the marbles to align with the adjustment holes. In addition, because There are many adjustment holes, so every time the length is adjusted, the marbles will go through one hole after another. Every time it enters the wrong hole, you have to press it again and re-adjust. It is inconvenient to use when adjusting the length. In addition, the current adjustment The holes are arranged at a certain distance. When in use, there will be holes with no suitable length. The crutches are not easy to use. When the crutches are in use, the foot pads are made of rubber pads, but the elasticity is limited, so when using the crutches In the middle, if it is pressed on an uneven place, its cushioning effect is not obvious. Finally, because the old man goes out now, he does not carry many things, and it is very inconvenient to carry a key on his body. How to set a key on the crutch? The place is also very convenient for the elderly.

Contents of the invention

Aiming at the deficiencies of the prior art, the utility model aims to provide a retractable crutch, which is convenient to find the hole position when adjusting the length, without pressing each hole, and can be fine-tuned at the same time to find a suitable length.

In order to achieve the above purpose, the utility model adopts the following technical solution: a retractable crutch, including an outer cylinder, an inner cylinder, a handshake and a foot pad, the outer cylinder is covered with the inner cylinder, and the feature is that the outer cylinder It has an arc-shaped rotating groove protruding outward along its axial direction, and the inner cylinder has an arc-shaped boss protruding along its axial direction. The arc width of the rotating groove is larger than that of the boss arc width, the boss is placed in the rotation groove, so that the outer cylinder and the inner cylinder can rotate within a small range, the outer cylinder has a plurality of adjustment holes parallel to the axial direction, the inner cylinder The cylinder has a marble. When the outer cylinder is screwed to a limit end relative to the inner cylinder, the marble is facing the position of the adjustment hole. A threaded pipe is fixedly connected to the top of the outer cylinder. The handshake The lower part is fixedly connected with a casing, and the casing is threadedly connected with the threaded pipe, and a fastening ring is provided under the casing, and the fastening ring is threaded with the threaded pipe, and the casing is threaded with the threaded pipe. After the fastening ring is relatively tightened, the rotation of the sleeve is limited.

Preferably, the foot pad is elastically connected to the inner cylinder.

Preferably, a spring seat is connected to the bottom of the inner cylinder, and the spring seat is connected to the foot pad through a spring.

Preferably, the handshake is hollow for placing keys.

The utility model has the following beneficial effects:

When the utility model is used, the inner and outer cylinders can be rotated within a certain range. When adjusting the length, the outer cylinder is rotated until the marbles are not facing the limit end of the adjustment hole to adjust the length, so that there is no need to press the holes one by one. , after adjusting to a suitable position, turn the outer cylinder to the other limit end of the marble facing the adjustment hole, so that it is very convenient to adjust; in addition, the utility model can be fine-tuned to find a suitable length for use. The spring setting is added to the foot pad, which has enough cushioning and is more stable to use. The position for placing keys is added, which is convenient for travel, simple and practical.

detailed description

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so as to understand the technical idea claimed by the utility model more clearly.

Referring to Figures 1 to 4, a retractable crutch includes an outer tube 1, an inner tube 2, a handshake 3 and a foot pad 6, the outer tube 1 covers the inner tube 2, and the inner tube 2 can be opposite to the outer tube. The cylinder 1 expands and contracts in the axial direction, the outer cylinder 1 has an arc-shaped rotating groove 11 that protrudes along the axial direction, and the inner cylinder 2 has an arc-shaped boss that protrudes along the axial direction 21, the arc width of the rotating groove 11 is greater than the arc width of the boss 21, and the boss 21 is placed in the turning groove 11, so that the outer cylinder 1 and the inner cylinder 2 can be smaller The outer cylinder 1 has a plurality of adjustment holes 13 parallel to the axial direction, and the inner cylinder 2 has a marble 5. When the outer cylinder 1 is rotated to a limit end relative to the inner cylinder 2 , the position of the marble 5 facing the adjustment hole 13, when screwed to the other extreme end, the marble 5 is not facing the position of the adjustment hole 13, and the top of the outer cylinder 1 is fixedly connected with a threaded pipe 12. The lower part of the handshake 3 is fixedly connected with a sleeve 31, the sleeve 31 is threadedly connected with the threaded pipe 12, the height of the handshake 3 can be adjusted when the handshake 3 is rotated, and a fastening is provided under the sleeve 31 Ring 4, the fastening ring 4 is threadedly matched with the threaded pipe 12, and the rotation of the sleeve 31 is limited after the sleeve 31 and the fastening ring 4 are relatively tightened, because the sleeve 31 and the fastening ring 4 After relative tightening, the two are extruded together, resulting in a slight deformation of the thread, so as to achieve the purpose of locking.

Specifically, the foot pad 6 is elastically connected to the inner cylinder 2, a spring seat 62 is connected to the bottom of the inner cylinder 2, and a spring 61 is connected between the spring seat 62 and the foot pad 6, so that When pressed to pebbles or uneven ground, there can be a certain buffer.

Specifically, the handshake 3 is hollow and is used to place keys. Specifically, a movable plate is provided on the side of the handshake 3, and the key can be put in, and the movable plate can be locked.

The inner and outer cylinders of the utility model can rotate within a certain range. When adjusting the length, the outer cylinder 1 rotates until the pinball 5 is not facing the limit end of the adjustment hole 13 to adjust the length, so that there is no need to press the holes one by one. Then, after adjusting to a suitable position, turn the outer cylinder 1 to the other end of the pinball 5 facing the adjustment hole 13, and the pinball 5 will easily align with the adjustment hole 13, so that the adjustment is very convenient; in addition, The utility model can be fine-tuned, the threaded connection at the 3 ends of the handshake can be fine-tuned to find the length suitable for each person, and the spring 61 is added to the foot pad 6, which has enough buffer and is more stable to use , It also increases the location of the key, which is convenient for travel, simple and practical.
