Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 A tension adjusting bolt includes an upper stabilizing plate 1 and a lower stabilizing plate 2. An upper bolt 11 is fixedly connected to the outer side of the upper stabilizing plate 1, a lower bolt 21 is fixedly connected to the outer side of the lower stabilizing plate 2, a connecting column 3 is fixedly connected to the outer side of the upper stabilizing plate 1, an installation tube 4 is fixedly connected to the outer side of the lower stabilizing plate 2, and an adjusting mechanism 5 is provided between the connecting column 3 and the installation tube 4.

[0027] The adjustment mechanism 5 includes a movable column 51, a sliding plate 52 fixedly connected to the outside of the movable column 51, a limit groove 53 opened in the inner wall of the mounting tube 4, an L-shaped rod 54 fixedly connected to the outside of the connecting column 3, a moving ring 55 fixedly connected to the outside of the L-shaped rod 54, a threaded tube 56 fixedly connected to the outside of the moving ring 55, and a screw 57 threadedly connected to the inside of the threaded tube 56.

[0028] Furthermore: the sliding plate 52 is symmetrically distributed on the outside of the movable column 51, the limiting groove 53 is adapted to the sliding plate 52, the movable column 51 is movably connected to the inside of the mounting tube 4 through the cooperation of the sliding plate 52 and the limiting groove 53, and the moving ring 55 is fixedly connected to the bottom of the connecting column 3 through the L-shaped rod 54. When the movable column 51 is located inside the mounting tube 4, the moving ring 55 is located outside the mounting tube 4.

[0029] It should be noted that: the sliding plate 52 enables the movable column 51 to move stably and directionally inside the mounting tube 4. The movement of the movable column 51 inside the mounting tube 4 changes the distance between the upper bolt 11 and the lower bolt 21. After the position adjustment is completed, the moving ring 55 will move to the outside of the mounting tube 4.

[0030] As a further improvement of this utility model, a shock-absorbing mechanism 6 is provided between the upper stabilizing plate 1 and the lower stabilizing plate 2. The shock-absorbing mechanism 6 includes a movable tube 61, and a miniature shock absorber 62 is movably connected inside the movable tube 61. A support rod 63 is fixedly connected to the top of the miniature shock absorber 62.

[0031] Furthermore: the movable tubes 61 are symmetrically distributed on the outside of the lower stabilizing plate 2, and the support rods 63 are symmetrically distributed on the outside of the upper stabilizing plate 1. The movable tubes 61 and the support rods 63 are connected by a miniature shock absorber 62. The miniature shock absorber 62 is movably connected inside the movable tubes 61 by a shock-absorbing spring, and the upper and lower ends of the shock-absorbing spring are respectively fixedly connected between the movable tubes 61 and the support rods 63.

[0032] It should be noted that the combined use of the movable tube 61, the support rod 63, and the miniature shock absorber 62 can improve the stability between the upper stabilizing plate 1 and the lower stabilizing plate 2. The shock-absorbing spring can also provide a buffering effect between the upper stabilizing plate 1 and the lower stabilizing plate 2.

[0033] Specifically: A shock-absorbing mechanism 6 is provided between the upper stabilizing plate 1 and the lower stabilizing plate 2. Movable tubes 61 are symmetrically distributed on the outside of the lower stabilizing plate 2, and support rods 63 are symmetrically distributed on the outside of the upper stabilizing plate 1. Movable tubes 61 and support rods 63 are connected by miniature shock absorbers 62, and the upper and lower ends of the shock-absorbing springs on the outside of the miniature shock absorbers 62 are respectively fixedly connected between the movable tubes 61 and the support rods 63.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] Working principle: By setting up an upper stabilizing plate 1 and a lower stabilizing plate 2, and upper bolts 11 and lower bolts 21 on their outer sides, when the tension needs to be adjusted, the movable column 51 at the bottom of the connecting column 3 moves inside the mounting tube 4, thereby adjusting the distance between the upper bolt 11 and the lower bolt 21. A sliding plate 52 is fixedly connected to the outer side of the movable column 51, and the sliding plate 52 is slidably connected inside the limiting groove 53, thus limiting the angle of the upper bolt 11. When the tension is adjusted to a suitable level, the moving ring 55 will be on the outer side of the mounting tube 4. By rotating the screw 57, the screw 57 rotates and moves inside the threaded tube 56. This causes one end of the screw 57 to abut against the mounting tube 4, thereby improving the stability between the mounting tube 4 and the connecting column 3 and preventing any impact on the normal use of the bolt. When the bolt is vibrated, a relative displacement will occur between the upper stabilizing plate 1 and the lower stabilizing plate 2. This displacement will cause the damping spring to compress or stretch. The damping spring will convert the vibration energy into elastic potential energy for storage. At the same time, the miniature damper 62 will also play a role. Its internal damping structure will consume some of the vibration energy and convert it into heat energy for dissipation. Through the synergistic effect of the damping spring and the miniature damper 62, the impact of vibration on the bolt connection is effectively reduced, ensuring the stability of the connection.
