Description
Technical Field
[0001] This utility model relates to the field of bolts, and more particularly to a bolt with an auxiliary fixing structure. Background Technology
[0002] Bolts play a crucial role as a common fastening element in numerous fields such as mechanical connections, equipment assembly, and building construction. Through their threaded structure, they engage with nuts or are directly screwed into components with internal threads to connect and secure different parts or components, ensuring the stability and reliability of the entire structure.
[0003] In the installation of conventional bolts, the bolt is usually passed through the hole of the connected parts and then the nut is tightened or directly screwed into the corresponding threaded hole.
[0004] However, when applied to scenarios involving vibration, impact, or large tolerances in the diameter of the connected parts, ordinary bolts cannot guarantee a stable connection effect, which can easily lead to the connection gradually loosening under vibration and affecting the safety of the overall structure. Therefore, a bolt with an auxiliary fixing structure is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a bolt with an auxiliary fixing structure, which aims to solve the problem of poor stability of ordinary bolts in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bolt with an auxiliary fixing structure, comprising a bolt, a fixing mechanism provided on the outer wall of the bolt, the fixing mechanism comprising an elastic sleeve, the inner wall of the elastic sleeve being fixedly connected to the unthreaded outer wall of the bolt, anti-slip texture being fixedly connected to the outer wall of the elastic sleeve, a retaining ring being fixedly connected to the unthreaded outer wall of the bolt, the top of the retaining ring contacting the bottom of the elastic sleeve, a sliding plate being slidably connected to the top outer wall of the bolt, and a rotating wheel being rotatably connected to the top outer wall of the bolt.
[0007] As a further description of the above technical solution: a central groove is provided inside the bolt, and a vertical rod is slidably connected in the inner wall of the central groove, with the outer wall of the vertical rod in contact with the inner wall of the rotating wheel.
[0008] As a further description of the above technical solution: the outer wall of the bolt is fixedly connected with an anti-reverse hook.
[0009] As a further description of the above technical solution: the top of the skateboard is hinged to a hinge plate, and the side of the hinge plate away from the skateboard is hinged to a mounting plate, and the outer wall of the mounting plate is fixedly connected to the outer wall of the vertical rod.
[0010] As a further description of the above technical solution: a limiting groove is formed on the top outer wall of the bolt, and the inner wall of the limiting groove is slidably connected to the outer wall of the slide plate.
[0011] As a further description of the above technical solution: a conical pressure head is fixedly connected to the bottom of the vertical rod, and a spiked plate is slidably connected to the bottom of the bolt.
[0012] As a further description of the above technical solution: a limiting rod is fixedly connected to the inner wall of the central groove, and the inner wall of the spike plate is slidably connected to the outer wall of the limiting rod.
[0013] As a further description of the above technical solution: the top of the bolt is threaded with a self-tapping screw.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, the stability of the bolt connection is effectively enhanced by the synergistic effect of the elastic sleeve and the anti-slip texture. During installation, the elastic sleeve is compressed and deformed, closely fitting the hole wall of the connected parts, filling the gap and buffering vibration, avoiding rigid contact between the bolt and the connected parts and wear. The anti-slip texture increases the friction, preventing the elastic sleeve from sliding or rotating, ensuring that the bolt can be stably connected even in a vibration environment.
[0016] 2. In this utility model, multiple auxiliary fixing structures improve the bolt fixing effect and applicability. Anti-reverse hooks prevent the bolt from reversing. Components such as the slide plate and the wheel work together to achieve top limiting. The conical pressure head and the spike plate provide auxiliary limiting from the bottom to prevent the bolt from shifting or rotating. The self-tapping screws can be further reinforced as needed to meet the bolt fixing strength requirements of different scenarios. Attached Figure Description

[0023] 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.
[0024] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a bolt with an auxiliary fixing structure, comprising a bolt 1. A fixing mechanism is provided on the outer wall of the bolt 1 to enhance the stability and fixing effect of the bolt 1 during use. The fixing mechanism includes an elastic sleeve 2, the inner wall of which is fixedly connected to the unthreaded outer wall of the bolt 1. The elastic sleeve 2 utilizes its own elasticity to better adapt to changes in the hole diameter of the connected parts during bolt 1 installation. When the bolt 1 is tightened, the elastic sleeve 2 is compressed and deformed, thus tightly fitting against the hole wall of the connected parts, providing a sealing and buffering effect. This prevents wear between the bolt 1 and the connected parts due to direct rigid contact, and also prevents wear under vibration. Bolt 1 is loosened to enhance the stability of the connection. Anti-slip texture 3 is fixedly connected to the outer wall of elastic sleeve 2. Anti-slip texture 3 can increase friction and prevent elastic sleeve 2 from rotating or sliding relative to each other in the hole of the connected parts, further ensuring the fixing effect of bolt 1. A retaining ring 4 is fixedly connected to the unthreaded outer wall of bolt 1. The top of retaining ring 4 contacts the bottom of elastic sleeve 2. Retaining ring 4 plays a limiting role and can prevent elastic sleeve 2 from sliding or displacing downward on bolt 1. A sliding plate 9 is slidably connected to the top outer wall of bolt 1. A rotating wheel 11 is rotatably connected to the top outer wall of bolt 1. After the sliding plate 9 slides to both sides, the rotating wheel 11 can be controlled to rotate to block the two sliding plates 9 from sliding closer to each other again.
[0025] Reference Figure 1 - Figure 3The bolt 1 has a central groove 12 inside, and a vertical rod 6 is slidably connected in the inner wall of the central groove 12. The central groove 12 provides sliding space for the vertical rod 6. The outer wall of the vertical rod 6 contacts the inner wall of the rotating wheel 11, which has a limiting effect on the rotating wheel 11. An anti-reverse hook 5 is fixedly connected to the outer wall of the bolt 1. After the bolt 1 is tightened, the anti-reverse hook 5 can prevent the bolt 1 from reversing. The top of the slide plate 9 is hinged to a hinge plate 8. The sliding of the slide plate 9 can drive the hinge plate 8 to move. The side of the hinge plate 8 away from the slide plate 9 is hinged to a mounting plate 7. Pressing down on the vertical rod 6, the mounting plate 7 applies a downward force to the hinge plate 8, thereby driving the two slide plates 9 away from each other. Then, by rotating the rotating wheel 11, the two protrusions of the rotating wheel 11 abut against the two slide plates 9, which has a limiting effect. The outer wall of the mounting plate 7 is fixedly connected to the outer wall of the vertical rod 6.
[0026] Reference Figure 2 - Figure 4 A limiting groove 10 is provided on the top outer wall of bolt 1. The limiting groove 10 provides sliding limit for slide plate 9 and restricts the movement path. The inner wall of the limiting groove 10 is slidably connected to the outer wall of slide plate 9. A conical pressure head 13 is fixedly connected to the bottom of vertical rod 6. When vertical rod 6 moves downward, it will drive the conical pressure head 13 to move downward. A spike plate 15 is slidably connected to the bottom of bolt 1. When conical pressure head 13 moves downward, it will squeeze the two spike plates 15 to move to both sides, and the spikes will play an auxiliary limiting and fixing effect. A limiting rod 14 is fixedly connected to the inner wall of central groove 12. The limiting rod 14 plays a limiting effect on spike plate 15. The inner wall of spike plate 15 is slidably connected to the outer wall of limiting rod 14. A self-tapping screw 16 is threadedly connected to the top of bolt 1. The self-tapping screw 16 can further fix the position of bolt 1 when needed. The middle part of self-tapping screw 16 is threadedly connected to bolt 1, and the lower half of self-tapping screw 16 is self-tapping thread.
[0027] Working principle: When using bolt 1, as bolt 1 is screwed in, the elastic sleeve 2 will undergo elastic deformation due to the compression of the hole wall. Since the inner wall of the elastic sleeve 2 is fixed to the unthreaded outer wall of bolt 1, the anti-slip texture 3 on its outer wall will be in close contact with the hole wall, increasing friction and preventing the elastic sleeve 2 from rotating or sliding in the hole. The deformation of the elastic sleeve 2 can better fill the gap between bolt 1 and the connected parts, playing a sealing and buffering role, avoiding direct rigid contact between the two and causing wear, and enhancing the connection stability. The retaining ring 4 prevents the elastic sleeve 2 from sliding downward on bolt 1, ensuring its positional stability. When bolt 1 is screwed in to a certain extent... Then, using external tools or manually, the slide plate 9 is made to slide within the limiting groove 10. When the slide plate 9 slides to both sides, it will cause the hinge plate 8 at the top to move. The sliding of the slide plate 9 will indirectly affect the vertical rod 6. Then, the vertical rod 6 is pressed down, and the vertical rod 6 applies a downward force to the hinge plate 8 through the mounting plate 7, which in turn causes the two slide plates 9 to move further away from each other. Then, the rotating wheel 11 is rotated so that its two protrusions will abut against the two slide plates 9, preventing the slide plates 9 from sliding closer to each other again. By using the mutual restraint of the rotating wheel 11 and the two slide plates 9, the position of the slide plate 9 is limited, and the fixing effect of the bolt 1 at the top is enhanced.
[0028] As the vertical rod 6 is pressed downwards, the conical pressure head 13 fixed at the bottom of the vertical rod 6 also moves downwards. The spiked plate 15, which is slidably connected to the bottom of the bolt 1, has its inner wall slidably connected to the outer wall of the limiting rod 14 and is limited. When the conical pressure head 13 presses down on the spiked plate 15, the spiked plate 15 will move to both sides under the restriction of the limiting rod 14. The spikes on the spiked plate 15 will penetrate into the connected parts, playing an auxiliary limiting and fixing role, preventing the bolt 1 from moving up and down or rotating in the connected parts. During the tightening of the bolt 1, the anti-reverse hook 5 will enter the connected parts along with the bolt 1. When the bolt 1 is tightened to the position, the anti-reverse hook 5 can prevent the bolt 1 from reversing, ensuring the reliability of the connection. If it is necessary to further fix the position of the bolt 1, a tool can be used to screw the self-tapping screw 16 into the threaded hole at the top of the bolt 1. The middle part of the self-tapping screw 16 is threadedly connected to the bolt 1, and the lower part is self-tapping thread, which can tap the thread on the connected parts and screw in by itself, further enhancing the fixing effect of the bolt 1.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
