Description

Technical Field

[0001] The utility model relates to the technical field of nuts, and in particular to an integrated nut with an anti-loosening structure. Background Art

[0002] Nuts are nuts, which are parts that are screwed together with bolts or screws for fastening. They are a kind of original parts that must be used in all manufacturing machinery. There are many kinds of nuts. The common ones we have are nuts of national standard, British standard, American standard, and Japanese standard. Nuts are divided into several types according to different materials, such as carbon steel, high strength, stainless steel, and plastic steel. Nuts are mostly made of metal materials. Nuts and bolts are a widely used mechanical fastener. When ordinary nuts and bolts are used to fix mechanical parts, due to the movement or vibration of the machine, the nuts are easy to loosen and fall off after a long time, causing the fixed parts to shift or loosen, which poses certain safety hazards and poor fixing performance.

[0003] At present, an existing integrated anti-loosening nut (such as patent number: CN213511620U) discloses an integrated anti-loosening nut, including a nut body, a bottom connecting ring and a tightening ring. A bolt hole is opened at the center position of the upper surface of the nut body, and a protective pad is fixedly installed outside the bolt hole and located on the upper surface of the nut body. The protective pad is made of rubber material, and a bottom connecting ring is fixedly installed on the outer wall of the bottom end panel of the nut body. Positioning holes are opened at the four corners of the upper surface of the bottom connecting ring. The positioning holes are laterally located and are threadedly connected with positioning pins on the outer wall of the bottom connecting ring. Beneficial effects: the anti-loosening nut with this structural design can effectively tighten and fix the bolts, thereby effectively preventing the bolts from loosening and falling out, and has good performance and safety in use. The tightening ring is detachable, which is convenient for replacing the tightening ring, has good performance in use, effectively reduces material waste, and reduces economic burden.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] 1. The existing device prevents the nut body from loosening by providing anti-skid grooves. However, after long-term use, the anti-skid grooves will be worn flat due to the vibration generated by continued operation, thereby reducing the anti-skid performance, and ultimately reducing the anti-skid property of the nut body. Therefore, the anti-loosening performance of the anti-loosening structure of the existing device will gradually weaken as the use time increases.

[0006] 2. The existing device enhances the anti-slip performance of the nut body to prevent loosening by setting anti-slip grooves. However, a problem with this device is that in the final stage of installing the nut, it is very difficult to tighten the nut body because the anti-slip grooves will cause the nut body to initially contact the mechanical device but not yet fully tightened. If strong force is used to tighten the nut body and the mechanical device, the anti-slip grooves will wear, thereby weakening the loosening effect. Therefore, the existing device is difficult to install and difficult to tighten. Utility Model Content

[0007] 1. Technical issues to be resolved

[0009] (II) Technical solution

[0010] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0011] An integrated nut with an anti-loosening structure comprises a nut body, a thread groove is arranged on the inner side of the nut body, a connecting ring is arranged on the bottom surface of the nut body, six fixing mechanisms are fixedly connected to the connecting ring, and the fixing mechanisms include a rotating shaft seat.

[0012] Preferably, six side surfaces of the nut body are each provided with a clamping groove, and threaded holes are each provided in the six clamping grooves.

[0013] Preferably, the fixing mechanism further comprises a connecting member, one end of which is provided with a rotating shaft groove, the other end of which is provided with a through hole, the rotating shaft seat is fixedly connected with the rotating shaft, and the connecting member is rotatably connected with the rotating shaft through the rotating shaft groove.

[0014] Preferably, the six connecting members are clamped in the six clamping grooves, the six through holes are respectively opposite to the six threaded holes, and the six through holes are threadedly connected with the six threaded holes to form fixing bolts.

[0015] Preferably: a plurality of tooth plates are fixedly connected to a side of the connecting ring away from the nut body.

[0016] Preferably: solid glue is smeared in the gaps between the plurality of tooth plates.

[0017] (III) Beneficial effects

[0018] 1. When installing the nut body, connect the connecting ring to the nut body through the fixing mechanism, directly connect the nut body to the bolt through the thread groove, when the nut body is screwed to the rear section, the tooth plate contacts the mechanical device first, the solid glue in the tooth plate adheres to the connection of the mechanical device, adheres the tooth plate and the connecting ring to the mechanical device, and the device as a whole is now installed. By setting the solid glue and providing gaps between the tooth plates, the friction between the solid glue and the connecting ring and the tooth plate is increased, making the connection between the nut body and the mechanical device more firm and stable, solving the problem that the anti-loosening performance of the existing device gradually weakens with the use time.

[0019] Second, the toothed plate and connecting ring provided in the present application will not increase friction and prevent slipping, so will not affect the installation of the entire device, thus solving the problem that the existing device is difficult to install and not easy to tighten.

[0027] The embodiment of the present application provides an integrated nut with an anti-loosening structure, which effectively solves the problem that the anti-loosening performance of the existing device gradually weakens with the use time, is difficult to install, and is not easy to tighten.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the technical problems that the anti-loosening performance of the existing device gradually weakens with the use time, the installation is difficult, and it is not easy to tighten. The overall idea is as follows:

[0029] In view of the problems existing in the prior art, the utility model provides an integrated nut with an anti-loosening structure, including a nut body 1, a thread groove 101 is provided on the inner side of the nut body 1, a connecting ring 2 is provided on the bottom surface of the nut body 1, and the connecting ring 2 is fixedly connected with six fixing mechanisms, and the fixing mechanisms include a rotating shaft seat 201.

[0030] The six side surfaces of the nut body 1 are all provided with clamping grooves 102 , and the six clamping grooves 102 are all provided with threaded holes 103 .

[0031] The fixing mechanism also includes a connecting member 203 , one end of which is provided with a shaft groove 204 , the other end of which is provided with a through hole 205 , the shaft seat 201 is fixedly connected with the rotating shaft 202 , and the connecting member 203 is rotatably connected with the rotating shaft 202 via the shaft groove 204 .

[0032] The six connecting members 203 are clamped in the six clamping grooves 102 , the six through holes 205 are respectively opposite to the six threaded holes 103 , and the six through holes 205 are threadedly connected with the fixing bolts 4 in cooperation with the six threaded holes 103 .

[0033] A plurality of tooth plates 3 are fixedly connected to a side of the connecting ring 2 away from the nut body 1 .

[0034] Solid glue is smeared in the gaps between the plurality of tooth plates 3 .

[0035] When installing the nut body 1, the connecting ring 2 is connected to the nut body 1 through the fixing mechanism, and the nut body 1 is directly connected to the bolt through the threaded groove 101. When the nut body 1 is screwed to the rear section, the tooth plate 3 first contacts the mechanical device, and the solid glue in the tooth plate 3 adheres to the connection of the mechanical device, and the tooth plate 3 and the connecting ring 2 are adhered to the mechanical device. At this time, the overall installation of the device is completed. By setting the solid glue and the gaps between the tooth plates 3, the friction between the solid glue and the connecting ring 2 and the tooth plate 3 is increased, so that the connection between the nut body 1 and the mechanical device is more firm and stable, which solves the problems that the anti-loosening performance of the existing device will gradually weaken with the use time, and the installation is more difficult and not easy to tighten.

[0036] Working principle:

[0037] In the first step, when installing the nut body 1, the connecting ring 2 is connected to the nut body 1 through a fixing mechanism, and the nut body 1 is directly connected to the bolt through the thread groove 101. When the nut body 1 is screwed to the rear section, the tooth plate 3 first contacts the mechanical device, and the solid glue in the tooth plate 3 adheres to the connection of the mechanical device, and the tooth plate 3 and the connecting ring 2 are adhered to the mechanical device. At this time, the overall installation of the device is completed. By setting the solid glue and the existence of gaps between each tooth plate 3, the friction between the solid glue and the connecting ring 2 and the tooth plate 3 is increased, making the connection between the nut body 1 and the mechanical device more firm and stable.

[0038] In the second step, when disassembling the nut body 1, it is necessary to remove the six fixing bolts 4, separate the connecting piece 203 from the snap-in groove 102, and separate the connecting ring 2 and the nut body 1. At this time, the nut body 1 can be unscrewed first. After unscrewing the nut body 1, use special tools to lift the connecting ring 2 and the tooth plate 3 from the connection of the mechanical device. At this time, the overall disassembly of the device is completed.

[0039] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
