Description

Technical Field

[0001] This utility model relates to the field of anti-loosening self-locking bolts, and in particular to an integrated anti-loosening self-locking bolt. Background Technology

[0002] Bolt devices are mainly used to tightly bind two or more things together. They rely on studs passing through the objects to be connected, and then nuts being tightened along the threads to clamp the objects in the middle, preventing them from separating or shifting.

[0003] Traditional bolted connections mainly consist of a bolt, nut, and washer. One end of the bolt has a nut of various shapes, such as hexagonal or round, for easy tightening with tools. The other end has a threaded stud, which can be screwed in and out like a screw. The nut is then tightened tightly onto the bolt. The washer is a small round piece placed under the bolt head or nut. When using a bolt, first pass the bolt through the parts to be connected, then tighten the nut along the bolt's threads. This allows the nut and bolt head to firmly clamp the parts together. The washer helps distribute pressure, preventing damage or loosening of the parts, thus securely fixing them together.

[0004] However, with the rapid development of modern society, bolts are being used more and more frequently in various industries. Traditional bolts can no longer meet the needs of society. Moreover, due to the relatively simple structure of traditional bolts, they are prone to loosening after being tightened for a long time, causing the connection to become loose, affecting the normal operation of equipment, and in severe cases, even causing accidents. To address this issue, an integrated anti-loosening self-locking bolt is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an integrated anti-loosening self-locking bolt, which aims to improve the problem of easy loosening of bolts in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated anti-loosening self-locking bolt includes a stud, a nut fixedly connected to the top of the stud, a nut threadedly connected to the outside of the stud, a support block slidably connected inside the stud, a spring plate fixedly connected to the rear side of the support block, and a spring fixedly connected to the end of the spring plate away from the support block.

[0008] As a further description of the above technical solution:

[0009] The nut has a hexagonal groove at the top, a cross groove at the center of the hexagonal groove, and a flat groove at the top.

[0010] As a further description of the above technical solution:

[0011] A washer is provided at the top of the stud, and the top of the washer is fixedly connected with an upper tooth, and the bottom of the washer is fixedly connected with a lower tooth.

[0012] As a further description of the above technical solution:

[0013] The washer abuts against the nut.

[0014] As a further description of the above technical solution:

[0015] The nut abuts against the support block.

[0016] As a further description of the above technical solution:

[0017] The support block is slidably connected inside the stud.

[0018] As a further description of the above technical solution:

[0019] The spring is disposed inside the stud.

[0020] As a further description of the above technical solution:

[0021] The bottom of the support block is sloped.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the nut rotates and moves along the thread on the stud at the end away from the nut. At the same time, multiple inclined support blocks are slidably connected inside the stud. When the nut rotates and moves, the support blocks are squeezed by the nut, which in turn pushes the spring plate to squeeze the spring and slide into the stud. When the nut moves above the support blocks, the spring also loses its squeezing force due to the sudden disappearance of the squeezing force, and instantly pushes the spring plate to rebound, causing the support blocks to extend out of the stud. At this time, the support blocks will block the nut from sliding down, thereby preventing the bolt from loosening.

[0024] 2. In this utility model, the top of the nut is provided with multiple different shapes to accommodate different tightening tools, and the washer at the bottom of the nut has teeth on both the upper and lower surfaces. During the tightening process of the bolt, the friction between the nut and the washer, and between the washer and the connecting object, can be increased, making the bolt more secure and less prone to loosening.

[0030] 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.

[0031] Reference Figure 1 , Figure 2 , Figure 3 One embodiment of this utility model is an integrated anti-loosening self-locking bolt. A nut 5 is fixedly connected to the top of the stud 1, a nut 9 is threadedly connected to the outside of the stud 1, a support block 10 is slidably connected inside the stud 1, a spring plate 12 is fixedly connected to the rear side of the support block 10, and a spring 11 is fixedly connected to the end of the spring plate 12 away from the support block 10. The top of the stud 1 is fixedly connected to the nut 5, and the outside of the stud 1 is also connected to the nut 9. The inside of the stud 1 is also slidably connected to the inclined support block 10. When the nut 9 rotates, it squeezes the inclined support block 10, which in turn pushes the spring plate 12, which is fixedly connected to the support block 10, into the stud 1. This causes the spring 11, which is fixedly connected to the end of the spring plate 12 away from the support block 10, to slide into the stud 1. When the nut 9 moves above the support block 10, the spring 11 also loses its squeezing force due to the sudden disappearance of the squeezing force. This causes the spring plate 12 to rebound instantly, which causes the support block 10 to extend out of the stud 1. At this time, the support block 10 will block the nut 9 from sliding down, thereby preventing the bolt from loosening.

[0032] Reference Figure 1 The nut 5 has a hexagonal groove 2 on its top, a cross groove 7 in the center of the hexagonal groove 2, and a flat groove 6 on its top. By providing the hexagonal groove 2, the cross groove 7, and the flat groove 6 on the top of the nut 5, the bolt can be adapted to different tightening tools.

[0033] Reference Figure 1The stud 1 has a washer 3 at its top, with an upper tooth 4 fixedly connected to the top of the washer 3 and a lower tooth 8 fixedly connected to the bottom of the washer 3. The washer 3 is fitted on the top of the stud 1, and the upper tooth 4 is fixedly connected to the top of the washer 3, while the lower tooth 8 is fixedly connected to the bottom. When the bolt is tightened, the upper tooth 4 and the lower tooth 8 of the washer 3 increase the friction between the nut 5 and the washer 3, making the bolt less likely to fall off.

[0034] Reference Figure 1 Washer 3 and nut 5 abut against each other. The top of washer 3 and nut 5 are tightly pressed together.

[0035] Reference Figure 1 , Figure 2 Nut 9 abuts against support block 10. When nut 9 rotates along the thread of stud 1, nut 9 will abut against support block 10.

[0036] Reference Figure 1 , Figure 3 The support block 10 is slidably connected inside the stud 1. When the nut 9 rotates and moves along the thread of the stud 1, the support block 10 will be squeezed and slide into the stud 1. When the nut 9 passes the support block 10, the squeezing force disappears, the spring 11 rebounds, and the support block 10 will slide inside the stud 1 again.

[0037] Reference Figure 1 , Figure 2 , Figure 3 Spring 11 is disposed inside stud 1. Spring 11 is disposed inside stud 1 and fixed to spring plate 12.

[0038] Reference Figure 1 , Figure 3 The bottom of the support block 10 is sloping. The end of the support block 10 that protrudes from the stud 1 is sloping to facilitate the rotation and movement of the nut 9, thereby pressing the support block 10 into the stud 1.

[0039] Working principle: During the anti-loosening self-locking process, the nut 9 rotates and moves along the thread on the stud 1 from the end away from the nut 5. At the same time, multiple inclined support blocks 10 are slidably connected inside the stud 1. When the nut 9 rotates and moves, the support blocks 10 are squeezed by the nut 9, which in turn pushes the spring plate 12 to squeeze the spring 11 and slide it into the stud 1. When the nut 9 moves above the support blocks 10, the spring 11 also loses its squeezing force due to the sudden disappearance of the squeezing force, and instantly pushes the spring plate 12 to rebound, so that the support blocks 10 protrude from the stud 1. At this time, the support blocks 10 and the bottom end of the nut 9 abut against each other, thereby preventing the nut 9 from loosening and sliding down.

[0040] During loading and unloading, the bolt nut 5 is equipped with different loading and unloading slots such as hexagonal slot 2, cross slot 7, and flat slot 6, which can be used with different loading and unloading tools, making loading and unloading convenient. In addition, the washer 3 that abuts against the nut 5 is designed with teeth, which increases the friction between the nut 5 and the washer 3 when the bolt is tightened, making the bolt less likely to fall off.

[0041] 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.
