Description

Technical Field

[0001] The utility model relates to the technical field of nuts, in particular to an anti-dropping and anti-vibration hexagonal nut. Background Art

[0002] The function of the nut is to connect mechanical equipment tightly and tighten it together with the bolt or screw. The nut is a nut, a component that must be used in all production and manufacturing machinery. According to the different materials, it is divided into several types, such as carbon steel, stainless steel, and non-ferrous metals (such as copper).

[0003] The nut on the bolt cannot be 100% fixed on the bolt, because the nut will inevitably loosen under high-frequency or long-term vibration of the bolt. However, the existing anti-slip and anti-vibration nuts all increase the contact medium between the threads on the nut and the threads on the bolt, and therefore can only delay the loosening of the nut to a certain extent. The current solution is to tighten the nut in time when the nut is found to be loose, but this nut and this method still have hidden dangers. When the nut is loose, some high-precision items are very likely to be damaged due to the looseness. When the nut is found to be loose and then tightened, it is too late. For this reason, we provide an anti-slip and anti-vibration hexagonal nut to solve the above problems. Utility Model Content

[0004] 1) Technical issues solved

[0005] The utility model aims to make up for the deficiencies of the prior art and provides an anti-dropping and anti-vibration hexagonal nut.

[0006] 2) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-slip and anti-vibration hexagonal nut, comprising a nut body, the inner wall of the nut body is threadedly connected with a threaded bolt, the outer surface of the threaded bolt is threadedly connected with a base layer, and the outer surface of the nut body is threadedly connected with a nut.

[0008] Furthermore, a rubber disc 1 is fixedly connected to the bottom surface of the nut body, a rubber tooth 1 is fixedly connected to the outer surface of the rubber disc 1, a rubber disc 2 is fixedly connected to the outer surface of the base layer, a rubber tooth 2 is fixedly connected to the outer surface of the rubber disc 2, and the outer surfaces of the rubber tooth 1 and the rubber tooth 2 rub against each other.

[0009] Furthermore, a hexagonal flange is fixedly connected to the outer surface of the nut, a prototype flange is provided on the outer surface of the nut, and an inclined surface is provided on the bottom surface of the prototype flange.

[0010] Furthermore, a positioning hole is opened on the inner side of the base layer, a positioning rod is slidably connected to the inner wall of the positioning hole, a protective shell is slidably connected to the outer surface of the positioning rod, and the bottom surface of the protective shell is fixedly connected to the outer surface of the base layer.

[0011] Furthermore, the outer surface of the nut body is fixedly connected to a support seat, the inner wall of the support seat is slidably connected to the outer surface of the positioning rod, the outer surface of the support seat is in close contact with a cover, and the bottom surface of the cover is fixedly connected to the top of the positioning rod.

[0012] Furthermore, the bottom surface of the prototype flange is covered with a rubber layer, and the inclined surface of the prototype flange is in close contact with the outer surface of the cover.

[0013] 3) Beneficial effects:

[0014] Compared with the prior art, the anti-dropout and anti-vibration hexagonal nut has the following beneficial effects:

[0015] 1. The utility model cooperates between the nut body, the base layer, the threaded bolt and the nut. The base layer is a conventional item that needs to be clamped by the nut body, and the nut can be screwed on the outside of the nut body, so that when the threaded bolt vibrates, it will not directly vibrate the nut, but directly vibrate the nut body to drive the nut. No matter how violently the nut vibrates, the nut body will not rotate if the nut is not separated from the nut body, so there will be no loosening. On the contrary, when the nut is loose, it only needs to be tightened again. Therefore, when the nut is found to be loose, the nut body itself is not loose, thereby solving the problem of finding that the nut is loose and it is too late to tighten it again.

[0016] 2. The utility model can increase the friction between the nut body through the cooperation between the rubber disc 1, the rubber disc 2, the rubber teeth 1 and the rubber teeth 2, and the rubber teeth 1 and the rubber teeth 2 can increase the friction between the two, thereby further reducing the loosening of the nut.

[0017] 3. The utility model uses the cooperation between the circular flange, the bolt body and the nut. The prototype flange can block rainwater from the vertical direction, thereby reducing the possibility of rust between the bolt body, the nut and the threaded bolt, and further improving the ability of the equipment to cope with severe weather.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-4 As shown, the utility model provides a technical solution: an anti-slip and anti-vibration hexagonal nut, comprising a nut body 1, a threaded bolt 2 is threadedly connected to the inner wall of the nut body 1, a base layer 3 is threadedly connected to the outer surface of the threaded bolt 2, and a nut 4 is threadedly connected to the outer surface of the nut body 1, the base layer 3 is a conventional item that needs to be clamped by the nut body 1, and the nut 4 can be threaded on the outside of the nut body 1, so that when the threaded bolt 2 vibrates, it will not directly vibrate the nut 4, but directly vibrate the nut body 1 to drive the nut 4, no matter how violently the nut vibrates, if the nut 4 does not separate from the nut body 1, the nut body 1 will still not rotate, so there will be no loosening. On the contrary, when the nut 4 is loose, it only needs to be retightened. Therefore, when the nut 4 is found to be loose, the nut body 1 itself is not loose, thereby solving the problem of finding that the nut is loose and then tightening it too late.

[0025] The bottom surface of the nut body 1 is fixedly connected with a rubber disk 5, the outer surface of the rubber disk 5 is fixedly connected with a rubber thread 6, the outer surface of the base layer 3 is fixedly connected with a rubber disk 2 7, the outer surface of the rubber disk 27 is fixedly connected with a rubber thread 2 8, the outer surfaces of the rubber thread 1 6 and the rubber thread 2 8 rub against each other, the nut body 1 can increase the friction between the rubber disk 1 5 and the rubber disk 2 7 through the friction between the rubber thread 1 6 and the rubber thread 2 8, and the friction between the two can be increased, thereby further reducing the loosening of the nut.

[0026] The outer surface of the nut 4 is fixedly connected with a hexagonal flange 9, and the outer surface of the nut 4 is provided with a prototype flange 10. The bottom surface of the prototype flange 10 is provided with an inclined surface 16. The hexagonal flange 9 can be conveniently tightened with a wrench, so that the nut 4 can be conveniently loosened. The prototype flange 10 can block rainwater from a vertical direction, thereby reducing the possibility of rust between the bolt body, the nut 4 and the threaded bolt 2, and further improving the ability of the equipment to cope with severe weather.

[0027] A positioning hole 11 is opened on the inner side of the base layer 3, and a positioning rod 12 is slidably connected to the inner wall of the positioning hole 11, and a protective shell 13 is slidably connected to the outer surface of the positioning rod 12. The bottom surface of the protective shell 13 is fixedly connected to the outer surface of the base layer 3. The positioning hole 11 and the protective shell 13 can increase the contact surface between the positioning rod 12, thereby reducing the possibility of the positioning rod 12 breaking, making the device more practical.

[0028] The outer surface of the nut body 1 is fixedly connected to a support seat 14, the inner wall of the support seat 14 is slidably connected to the outer surface of the positioning rod 12, the outer surface of the support seat 14 is in contact with a cover 15, the bottom surface of the cover 15 is fixedly connected to the top of the positioning rod 12, and the insertion rod can pass through the support seat 14 and enter the positioning hole 11, so that the nut body 1 is locked and cannot rotate, thereby reducing the loosening of the nut body 1.

[0029] The bottom surface of the prototype flange 10 is covered with a rubber layer. The inclined surface 16 of the prototype flange 10 is in close contact with the outer surface of the cover 15. The rubber layer can increase the friction between the inclined surface 16 and the cover 15, and because the inclined surface 16 is attached to the cover 15, the positioning rod 12 cannot fall off, thereby further preventing the nut from rotating.

[0030] Working principle: When the device needs to be used, a positioning hole 11 is pre-opened on the base layer 3, and then the nut body 1 is screwed onto the threaded bolt 2, so that the nut is as close to the base layer 3 as possible, and the positioning rod 12 is inserted into the support seat 14 and the positioning hole 11, and then the nut 4 is screwed onto the outer surface of the nut body 1, so that the prototype flange 10 is pressed on the positioning rod 12 through the cover 15.

[0031] When the threaded bolt 2 and the base layer 3 vibrate, the nut body 1 will rotate slightly and become loose as usual. However, since the positioning rod 12 is stuck in the support seat 14, the nut body 1 itself cannot rotate. The vibration can only be transmitted to the nut 4 through the nut body 1, causing the nut 4 to start to rotate slightly. However, before the nut 4 completely separates from the nut body 1, it can limit and suppress the positioning rod 12 to prevent it from falling off from the support seat 14 and the positioning hole 11, thereby preventing the nut body 1 from loosening before the construction personnel perform maintenance.
