Description

Technical Field

[0001] The utility model relates to the technical field of rotating shaft connectors, and specifically relates to a rotating shaft structure with high reliability. Background Technique

[0002] A rotating shaft is a rotating component commonly used in fields such as automobiles, mainly used to connect two or more product components. By using a rotating shaft, multiple product components can be transformed into a whole for work, thereby providing the effects of connection and support for rotation of the product.

[0003] The above-mentioned and existing related technologies often have the following defects: After connecting product components with a rotating shaft structure, due to the relatively long length of the rotating shaft body, during the rotation of the components connected by the rotating shaft structure, the rotating shaft body is prone to shaking, which easily leads to a reduction in the reliability of the rotating shaft structure during long-term use.

[0004] Therefore, we propose a rotating shaft structure with high reliability. Content of the Utility Model

[0012] Preferably, a fixing rod is slidably connected to the inner wall of the second slider. The fixing rod is fixedly connected to the surface of the second sliding groove on the fixing block. A second spring is sleeved on the surface of the fixing rod, and both ends of the second spring are fixedly connected to the second slider and the fixing block respectively.

[0013] The effect achieved by the above components is that by providing the fixing rod, the position of the second spring can be restricted, and by providing the second spring, the position of the second slider can be restricted.

[0030] See also Figures 1-5, the present utility model provides a technical solution: a shaft structure with high reliability, including a fixed block 1. Two shaft bodies 2 are rotatably connected to the inner wall of the fixed block 1. Rotating blocks 3 are fixedly connected to the surfaces of the two shaft bodies 2. Two mounting plates 4 are installed on the upper surface of the fixed block 1. Arc-shaped plates 7 are installed on the upper surfaces of the two mounting plates 4, and the upper surface of the arc-shaped plate 7 is arc-shaped. By providing two shaft bodies 2, the length of a single shaft can be reduced, thereby minimizing the shaking of the shaft body 2 during rotation as much as possible. By providing the arc-shaped plate 7, it can support the rotating block 3 during rotation, improving the reliability during rotation.

[0031] The following specifically describes its overall specific settings and functions.

[0032] As Figures 1-5 shown, two second chutes are opened on the upper surface of the fixed block 1. Second sliders 11 are slidably connected to the surfaces of the second chutes on the two fixed blocks 1, and the second sliders 11 are fixedly connected to the mounting plates 4. The second sliders 11 slidably connected to the surfaces of the second chutes on the fixed block 1 can move, thus ensuring that the mounting plates 4 can move. First chutes are opened on the upper surfaces of the two mounting plates 4. First sliders 5 are slidably connected to the surfaces of the first chutes on the mounting plates 4. A moving block 6 is fixedly connected to the side of the first slider 5 close to the arc-shaped plate 7, and the moving block 6 is fixedly connected to the arc-shaped plate 7. By providing the first slider 5, the moving block 6 can be connected to the mounting plate 4 and the moving block 6 can move, thus ensuring that the arc-shaped plate 7 can move. A fixed rod 12 is slidably connected to the inner wall of the second slider 11. The fixed rod 12 is fixedly connected to the surface of the second chute on the fixed block 1. A second spring 13 is sleeved on the surface of the fixed rod 12, and the two ends of the second spring 13 are respectively fixedly connected to the second slider 11 and the fixed block 1. By providing the fixed rod 12, the position of the second spring 13 can be restricted. By providing the second spring 13, the position of the second slider 11 can be restricted.

[0033] First fixing plates 8 are fixedly connected to the upper surfaces of the two mounting plates 4. A sliding rod 9 is fixedly connected to the side of the first fixing plate 8 close to the moving block 6. The sliding rod 9 is slidably connected to the inner wall of the moving block 6. By providing the first fixing plate 8, the sliding rod 9 can be connected to the mounting plate 4. The sliding rod 9 slidably connected to the inner wall of the moving block 6 does not affect the movement of the moving block 6. A first spring 10 is sleeved on the surface of the sliding rod 9, and the two ends of the first spring 10 are respectively fixedly connected to the moving block 6 and the first fixing plate 8. By providing the first spring 10, the position of the moving block 6 can be restricted. By providing the first fixing plate 8, it is convenient to install the first spring 10. Second fixing plates 14 are fixedly connected to the upper surfaces of the two mounting plates 4, and the second fixing plates 14 are fixedly connected to the sliding rod 9. By providing the second fixing plates 14, the stability of the connection between the sliding rod 9 and the mounting plate 4 can be improved.

[0034] Working principle: When rotating the rotating shaft structure, the control rotating block 3 drives the rotating shaft body 2 to rotate inside the inner wall of the fixed block 1. At this time, the rotating block 3 rotates close to the arc-shaped plate 7, so that the arc-shaped plate 7 can support the rotating block 3. At this time, the rotation of the rotating block 3 can drive the moving block 6 to slide on the surface of the sliding rod 9 and the second slider 11 to slide on the surface of the fixed rod 12. During the movement of the moving block 6, the first slider 5 slides on the surface of the first chute of the mounting plate 4. Thus, the damage caused by the pressure exerted by the rotating block 3 on the arc-shaped plate 7 can be reduced through the movement of the arc-shaped plate 7, improving the reliability of the use of the arc-shaped plate 7. By setting the first fixing plate 8 and the second fixing plate 14, the sliding rod 9 can be installed. By setting the first spring 10 and the second spring 13, the positions of the moving block 6 and the second slider 11 can be restricted. By setting two rotating shaft bodies 2 and rotating blocks 3, the length of the rotating shaft body 2 is reduced, so that when the components connected by the rotating shaft structure rotate, the situation of the rotating shaft body 2 shaking can be avoided as much as possible, thus ensuring the reliability of the rotating shaft structure as much as possible. By setting the arc-shaped plate 7, during the rotation of the rotating block 3, the arc-shaped plate 7 can play a supporting role for the rotating block 3, thus avoiding the deflection trend of the rotating block 3 as much as possible and improving the reliability of the use of the rotating shaft structure. By setting the first slider 5 and the second slider 11, it is ensured that the rotating block 3 can move, thus reducing the damage caused by the rotating block 3 due to bearing pressure as much as possible and ensuring the reliability of the use of the rotating shaft structure as much as possible.
