Description

Technical Field

[0001] This utility model belongs to the field of armrest frame technology, specifically relating to an armrest frame that can improve grip comfort. Background Technology

[0002] The handrail frame is a key component ensuring the safety and comfort of people with mobility impairments, and its design revolves around functionality and ergonomics. In terms of materials, walking handrail frames are mostly made of high-strength aluminum alloy or stainless steel. The former is lightweight and corrosion-resistant, while the latter is sturdy and durable, ensuring the frame stably supports the body's weight. The surface is often covered with non-slip rubber, soft silicone, or other materials, which enhance friction to prevent slippage and improve grip comfort. In terms of structural design, it adopts an ergonomic curved or elliptical shape to conform to the natural grip curve of the hand, reducing hand pressure; the edges are rounded to prevent scratches. Some walking handrail frames also have height adjustment functions to accommodate users of different heights; some incorporate shock-absorbing structures to reduce hand vibration during use. Furthermore, non-slip textures or raised designs further enhance grip stability, providing reliable support for users during walking, standing, and other movements, ensuring safe mobility.

[0003] Currently, existing handrail frames are designed to be height-adjustable to accommodate users of different heights. However, traditional handrail frames are often fixed with screws. Therefore, when adjusting the height of the handrail frame, the screws must be removed first, and then the handrail frame must be adjusted to the appropriate position before the screws are screwed into the corresponding threaded holes to secure it. This adjustment method is very inconvenient, and the height of the handrail frame can only be adjusted according to the hole spacing, which is quite limiting and reduces grip comfort. Utility Model Content

[0004] The purpose of this utility model is to provide a handrail frame that can improve grip comfort. It aims to solve the problem that existing handrail frames, in order to facilitate use by users of different heights, usually allow for height adjustment of the handrail frame. However, traditional handrail frames are often fixed by screws. Therefore, when it is necessary to adjust the height of the handrail frame, the screws must be removed first, and then the handrail frame must be adjusted to a suitable position before the screws are screwed into the corresponding threaded holes to fix it. However, this adjustment method is very inconvenient to operate, and the height of the handrail frame can only be adjusted according to the hole spacing, which is quite limited and reduces the grip comfort.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a handrail frame that can improve grip comfort, comprising two first columns and two second columns, wherein a handrail frame is inserted through the top of the first columns and the second columns, and a rubber sleeve is fitted onto the outer wall of the handrail frame; A connecting frame is fixedly connected between the two second columns.

A connecting frame 5 is fixedly connected between the two second columns 2. A first connecting plate 6 and a second connecting plate 7 are fixedly connected between the first column 1 and the second column 2. A threaded rod 8 passes through the top of the first connecting plate 6. A threaded sleeve 9 is threadedly connected to the outer wall of the threaded rod 8. A connecting rod 10 is fixedly connected to the outer wall of the threaded sleeve 9. A guide rod 11 is fixedly connected between the first connecting plate 6 and the second connecting plate 7. An opening 12 is opened on the outer wall of the first column 1 and the second column 2. It should be noted that the outer wall of the rubber sleeve 4 is provided with anti-slip texture, which can improve the grip friction for the user.

[0018] Preferably, the through end of the lead screw 8 forms a rotating connection structure with the second connecting plate 7 through a bearing, the end of the connecting rod 10 away from the threaded sleeve 9 is sleeved on the outer wall of the guide rod 11, and the end of the connecting rod 10 away from the threaded sleeve 9 passes through the opening 12 and is fixedly connected to the outer wall of the handrail frame 3.

[0019] In practical use, the screw 8 is rotated counterclockwise by the knob, so that the threaded sleeve 9 connected to the outer wall can drive the connecting rod 10 to move downward along the guide rod 11. As the connecting rod 10 moves downward, the handrail frame 3, which is fixedly connected through the opening 12, can also move downward together. Conversely, by rotating the screw 8 clockwise with the knob, the threaded sleeve 9 connected to its outer wall thread can drive the connecting rod 10 to move upward along the guide rod 11. As the connecting rod 10 moves upward, the handrail frame 3, which is fixedly connected through the opening 12 at one end, can also move upward together, thereby conveniently realizing the height adjustment of the handrail frame 3 and avoiding the limitations of traditional adjustment methods, further improving grip comfort.

[0020] Preferably, the bottom of the first column 1 and the second column 2 is provided with a rectangular groove 13, the bottom of the first column 1 and the second column 2 is provided with a support leg 14, the top of the support leg 14 is fixedly connected with a rectangular block 15, the outer wall of the first column 1 and the second column 2 is threaded with a mounting bolt 16, the outer wall of the rectangular block 15 is provided with a threaded hole 17, the rectangular block 15 can pass through the bottom of the first column 1 and the second column 2 through the rectangular groove 13, and the support leg 14 can form a threaded connection structure with the first column 1 or the second column 2 through the rectangular groove 13, the rectangular block 15, the mounting bolt 16, and the threaded hole 17.

[0021] In practical use, the rectangular block 15 at the top of the support leg 14 is inserted into the rectangular groove 13 at the bottom of the first column 1 or the second column 2, and then the mounting bolt 16 is passed through the outer wall of the first column 1 or the second column 2 and threaded through the threaded hole 17 to connect it with the rectangular block 15, thereby enabling the support leg 14 to be installed conveniently.

[0022] Working principle: First, the handrail frame is formed by assembling the first column 1, the second column 2, the handrail frame 3, the rubber sleeve 4, the connecting frame 5, the first connecting plate 6, and the second connecting plate 7. When the height of the handrail frame 3 needs to be adjusted to improve grip comfort, the screw 8 is turned counterclockwise by turning the knob, so that the threaded sleeve 9 connected to its outer wall can drive the connecting rod 10 to move downward along the guide rod 11. As the connecting rod 10 moves downward, the handrail frame 3, which is fixedly connected to it through the opening 12, can also move downward together. Conversely, turning the screw 8 clockwise by turning the knob can drive the connecting rod 10 to move the threaded sleeve 9 connected to its outer wall. 10 moves upward along the guide rod 11. As the connecting rod 10 moves upward, one end of it passes through the opening 12 and is fixedly connected to the handrail 3, which can also move upward together. This allows for convenient height adjustment of the handrail 3 and avoids the limitations of traditional adjustment methods, further improving grip comfort. Furthermore, by inserting the rectangular block 15 at the top of the support leg 14 into the rectangular groove 13 at the bottom of the first column 1 or the second column 2, and then passing the mounting bolt 16 through the outer wall of the first column 1 or the second column 2, and using the threaded hole 17 to thread it to the rectangular block 15, the support leg 14 can be installed conveniently.
