Description

Technical Field

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

[0002] A nut is a nut that is a part that tightly connects mechanical equipment. Nuts and bolts of the same specifications can be connected together through the inner thread. However, after the nut and bolt are connected, the nut will loosen and fall off due to external vibration.

[0003] A Chinese patent discloses a nut (authorization announcement number CN216158071U), which includes a nut body, a first protrusion and a second protrusion on either side of the nut body, and the first protrusion, the second protrusion and the nut body form a groove. This embodiment provides a nut that can avoid the problem of slipping caused by rust during disassembly, so that the nut can be tightened or disassembled smoothly.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the existing nuts and bolts are subjected to vibration, the nuts are not tightly connected to each other, and the nuts are moved by the impact force, causing the bolts and nuts to loosen and create gaps, making the connection between the objects fixed by the bolts and nuts loose and shaking, creating safety hazards and reducing the practicality of the nuts. Utility Model Content

[0005] The technical problem to be solved by the utility model is that: the prior art has the disadvantage of being unable to prevent the nut from loosening, so we propose a nut with an anti-loosening function.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a nut with anti-loosening function, comprising a nut body, a first threaded hole is opened inside the nut body, inclined plates are fixedly connected to the four sides of the bottom of the nut body, and the surface of the inclined plate is fixedly connected to the threaded line, and circular holes are opened on both sides of the bottom of the nut body, a round rod is fixedly connected to the top of the inner wall of the circular hole, a slide plate is slidably connected to the surface of the round rod, a push ring is fixedly connected to the opposite surface of the slide plate, an extension block is fixedly connected to the bottom of the round rod, and a lifting screw is connected to the internal thread of the extension block.

[0007] Preferably, a spring is fixedly connected to the top of the inner wall of the circular hole, and the bottom of the spring is fixedly connected to the top of the slide plate.

[0008] Preferably, second threaded holes are formed around the push ring, and the inner wall of the second threaded hole is threadedly connected with a first screw.

[0009] Preferably, a rubber block is fixedly connected to the top of the nut body, and the rubber blocks are in a plurality and evenly distributed on the top of the nut body.

[0010] Preferably, the inner diameter of the spring is slidably connected to the surface of the round rod.

[0011] Preferably, the outer side of the inclined plate is designed with an oblique angle, and the inner diameter of the push ring is matched with the surface of the inclined plate.

[0012] Preferably, the inclined plate is made of a highly elastic alloy material.

[0013] Technical effects and advantages of the utility model:

[0014] In the utility model, a worker screws the lifting screw upward, so that the lifting screw pushes the slide plate upward to slide upward on the surface of the round rod. At the same time, the round rod drives the push ring to move upward, so that the push ring squeezes the inclined plate to contract and clamps the bolt, so that the thread line and the thread on the bolt surface are tightly attached, thereby increasing the friction and contact area, preventing the nut body from loosening and the bolt from detaching from the nut body, and making the connection between the nut body and the bolt more firmly.

[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figure 1 - Figure 4 As shown, the utility model provides a technical solution: a nut with an anti-loosening function, comprising a nut body 1, a first threaded hole 2 is opened inside the nut body 1, an inclined plate 3 is fixedly connected to the four sides of the bottom of the nut body 1, and a thread line 4 is fixedly connected to the surface of the inclined plate 3, and a circular hole 5 is opened on both sides of the bottom of the nut body 1, and a round rod 6 is fixedly connected to the top of the inner wall of the circular hole 5, and a slide plate 7 is slidably connected to the surface of the round rod 6, and a push ring 8 is fixedly connected to the opposite surface of the slide plate 7, and an extension block 9 is fixedly connected to the bottom of the round rod 6, and a lifting screw 10 is connected to the internal thread of the extension block 9. When the staff screws the lifting screw 10 upward, the lifting screw 10 pushes the slide plate 7 upward to slide upward on the surface of the round rod 6, and the round rod 6 drives the push ring 8 to move upward, so that the push ring 8 squeezes the inclined plate 3 to contract, and clamps the bolt, so that the thread line 4 is in close contact with the thread on the surface of the bolt, thereby increasing its friction and contact area, preventing the nut body 1 from loosening and the bolt from detaching from the nut body 1, so that the nut body 1 and the bolt are more firmly connected.

[0024] Reference Figure 3 As shown, in this embodiment: the top of the inner wall of the circular hole 5 is fixedly connected with a spring 11, and the bottom of the spring 11 is fixedly connected to the top of the slide plate 7. When the staff member screws the lifting screw 10 upward to drive the slide plate 7 to move, the slide plate 7 presses the spring 11 upward to store force. When the staff member needs to release the clamping of the push ring 8 on the inclined plate 3, the lifting screw 10 is screwed downward, and the spring 11 releases the force generated, so that the spring 11 rebounds and pushes the slide plate 7 to drive the push ring 8 to move downward, releasing the clamping of the push ring 8 on the inclined plate 3, so that the staff member can control the position of the push ring 8 through the force generated by the spring 11.

[0025] Reference Figure 5 and Figure 6 As shown, in the present embodiment: second threaded holes 12 are provided on all sides of the push ring 8, and the inner wall of the second threaded hole 12 is threadedly connected with a first screw 13. The staff screws the first screw 13 inward, and the first screw 13 moves inward through the threaded connection between the first screw 13 and the second threaded hole 12, and pushes the inclined plate 3 so that the inclined plate 3 and the thread line 4 are close to the bolt, and the position of the bolt and the inclined plate 3 is adjusted to reinforce the bolt to prevent it from loosening.

[0026] Reference Figure 1 , Figure 2 and Figure 5As shown, in this embodiment: a rubber block 14 is fixedly connected to the top of the nut body 1, and the number of rubber blocks 14 is several and evenly distributed on the top of the nut body 1. When the staff screws the bolt into the first threaded hole 2, by opening a plurality of rubber blocks 14 on the top of the nut body 1, the friction between the nut body 1 and the connection object is increased, preventing the nut body 1 from loosening after tightening, so that the nut body 1 and the bolt are more tightly connected.

[0027] Reference Figure 3 As shown, in this embodiment: the inner diameter of the spring 11 is slidably connected to the surface of the round rod 6. When the slide plate 7 moves under the force generated by the spring 11, the round rod 6 limits the direction of the elastic force generated by the spring 11 through the sliding connection between the spring 11 and the round rod 6, so that the sliding of the round rod 6 and the slide plate 7 is smoother.

[0028] Reference Figure 1 and Figure 2 As shown, in this embodiment: the outer side of the inclined plate 3 is designed with an angle, and the inner diameter of the push ring 8 is adapted to the surface of the inclined plate 3. Through the design of the angle of the outer side of the inclined plate 3, the push ring 8 can move more smoothly on the surface of the inclined plate 3, and the contact area between the push ring 8 and the inclined plate 3 is increased, preventing the generation of a gap between the inclined plate 3 and the push ring 8, so that the contraction of the inclined plate 3 pressed by the push ring 8 is more precise.

[0029] Reference Figure 1 and Figure 2 As shown, in this embodiment: the material of the inclined plate 3 is made of a high-elastic alloy material. By using the material of the inclined plate 3 to be made of a high-elastic alloy material, the inclined plate 3 has higher elasticity, which is more conducive to screwing the bolts into the inclined plate 3. At the same time, the highly elastic material is more conducive to the push ring 8 pressing the inclined plate 3 to tighten it. At the same time, the alloy material is not easy to rust, which increases its service life.

[0030] The utility model works as follows: the staff member screws the lifting screw 10 upwards, so that the lifting screw 10 pushes the slide plate 7 upwards to slide upwards on the surface of the round rod 6, and at the same time the round rod 6 drives the push ring 8 to move upwards, so that the push ring 8 squeezes the inclined plate 3 to contract, clamps the bolt, and makes the thread line 4 and the thread on the surface of the bolt close to each other, increases the friction and contact area, prevents the nut body 1 from loosening and the bolt from detaching from the nut body 1, and makes the connection between the nut body 1 and the bolt more firmly. When the staff member screws the lifting screw 10 upwards to drive the slide plate 7 to move, the slide plate 7 The spring 11 is pressed upward to store force. When the staff needs to loosen the clamping of the push ring 8 on the inclined plate 3, the lifting screw 10 is turned downward, and the spring 11 releases the force generated, so that the spring 11 rebounds and pushes the slide plate 7 to drive the push ring 8 to move downward, releasing the clamping of the push ring 8 on the inclined plate 3, so that the staff can control the position of the push ring 8 through the force generated by the spring 11, and the staff screws the first screw 13 inward, and the first screw 13 is threadedly connected with the second threaded hole 12 to move the first screw 13 inward, and push the inclined plate 3 so that the inclined plate 3 and the threaded hole 12 are connected. The wire 4 is close to the bolt, and the position of the bolt and the inclined plate 3 is adjusted to reinforce the bolt to prevent it from loosening. When the staff screws the bolt into the first threaded hole 2, a plurality of rubber blocks 14 are provided on the top of the nut body 1 to increase the friction between the nut body 1 and the connection object, so as to prevent the nut body 1 from loosening after being tightened, so that the nut body 1 and the bolt are connected more tightly. When the slide plate 7 moves under the force generated by the spring 11, the spring 11 is connected to the round rod 6 through sliding, so that the round rod 6 limits the direction of the elastic force generated by the spring 11, so that the round rod 6 and the slide plate 7 slide more smoothly. The design of the outer bevel angle of the inclined plate 3 makes the push ring 8 move more smoothly on the surface of the inclined plate 3, increasing the contact area between the push ring 8 and the inclined plate 3, preventing the formation of a gap between the inclined plate 3 and the push ring 8, making the push ring 8 press the inclined plate 3 to shrink more precisely. The inclined plate 3 is made of a high-elastic alloy material, so that the inclined plate 3 has higher elasticity, which is more conducive to the bolts being screwed into the inclined plate 3. At the same time, the high-elastic material is more conducive to the push ring 8 pressing the inclined plate 3 to tighten it. At the same time, the alloy material is not easy to rust, which increases its service life.
