Description

Technical Field

[0001] This utility model belongs to the field of fastening nut technology, and in particular relates to a self-locking special-shaped fastening nut for vehicles. Background Technology

[0002] Automotive self-locking custom-shaped fasteners are fasteners designed specifically for automotive and other applications. They combine the self-locking function of custom-shaped nuts with special shape structures to meet complex installation requirements and anti-loosening requirements. These nuts not only have custom shapes to adapt to specific installation environments, but also incorporate a self-locking mechanism to ensure that they remain tight under vibration or impact conditions.

[0003] Currently available automotive self-locking custom-shaped fasteners have the following problems when used:

[0004] Traditional self-locking special-shaped fastening nuts for automobiles usually use small bolts to lock the bolts inside the self-locking special-shaped fastening nuts. During the vehicle's operation, there will be frequent bumps, and the small bolts used to lock the bolts may still loosen. In addition, the small bolts need to be unscrewed during disassembly, which is a rather cumbersome operation. Utility Model Content

[0005] The purpose of this utility model is to provide a self-locking irregular-shaped fastening nut for vehicles to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: A self-locking, irregularly shaped fastening nut for vehicles includes a nut body. A groove is formed on the surface of the nut body. A fixing shell is fitted onto the surface of the nut body. A through hole is formed on the surface of the nut body. A limiting groove is formed inside the groove. A locking block is inserted into the groove. A sliding plate is fixedly connected to the surface of the locking block. The sliding plate is within the limiting groove. The locking block is fitted to the inner side of the fixing shell. A spring-connected insertion rod is attached to the surface of the fixing shell. The insertion rod penetrates the fixing shell and is inserted into the through hole, thus locking the nut body when tightened with a bolt. The block slides outward in the groove. Through the limiting groove opened in the groove, the locking block will not slide out, and only the inclined surface of the nut body is exposed, which will not affect the use of the nut body. Then the fixing shell is sleeved on the surface of the nut body. During the downward movement, it will squeeze the exposed locking block, causing it to move inward until it tightens the bolt. It will not loosen due to the vehicle shaking for a long time, and prevent the nut body from rotating during shaking. Continue to press down the fixing shell until the inner surface of the fixing shell is inserted into the through hole opened on the surface of the nut body through the spring-connected plug, preventing the fixing shell from falling off. This greatly increases the locking stability of the device.

[0007] Preferably, a washer is fixedly connected to the bottom of the nut body, a sealing block is fixedly connected to the surface of the washer, a sealing gasket is fixedly connected to the surface of the sealing block, a sealing groove is opened at the bottom of the sealing block, and a glue inlet is fixedly connected to the top of the sealing block. In this way, when the nut body is tightened, the sealing gasket at the bottom of the sealing block will press against the plane, increasing the sealing performance. Then, waterproof glue is injected into the glue inlet until the waterproof glue fills the sealing groove. At this time, the connection between the nut body and the bolt will be fully isolated from the outside world, preventing rainwater from entering the connection when the vehicle is driving in rainy weather, which would cause rust and affect its service life.

[0008] Preferably, the surface of the fixed shell is fixedly connected with six fixing tubes, and the number of the insertion rods is six. In this way, the fixed tubes increase the contact area between the insertion rods and the fixed shell, prevent the insertion rods from shaking, and increase the stability of the device.

[0009] Preferably, a baffle is fixedly connected to the surface of the nut body, the baffle is distributed in a circular pattern, and a reinforcing plate is fixedly connected to the surface of the nut body. In this way, the reinforcing plate is also fixedly connected to the surface of the nut body, which increases the compressive strength of the nut body.

[0010] Preferably, the surface of the fixed shell is fixedly connected with protrusions, which are distributed in a circular pattern. The protrusions provide force points, and the fixed shell can be slid down by tapping the protrusions. It can also be opened by tapping the protrusions when it is removed, which is more convenient.

[0011] Preferably, the bottom of the washer is fixedly connected with an anti-slip ridge, which is distributed in a circular pattern. Thus, an anti-slip ridge with an inclined surface is also fixedly connected to the bottom of the washer at the bottom of the nut body. The resistance is small when tightening normally, and when it is to be rotated in the opposite direction, its other side will clamp the plane to prevent it from rotating.

[0012] The self-locking irregular-shaped fastening nut for vehicles of this utility model has the following advantages:

[0013] 1. This self-locking special-shaped fastening nut for vehicles has a through hole on the surface of the nut body. A locking block is inserted into a groove on the surface of the nut body. The locking block is then fitted inside a fixing shell that is sleeved on the surface of the nut body until a spring-connected insert rod is inserted into the through hole on the surface of the fixing shell. A limiting groove is provided inside the groove, and a sliding plate is fixedly connected to the surface of the locking block. When the nut body is tightened, the locking block slides outward in the groove. Due to the limiting groove in the groove, the locking block will not slide out, and only its inclined surface is exposed on the surface of the nut body, which will not affect the use of the nut body. Then, the fixing shell is sleeved on the surface of the nut body. During the downward movement, it will squeeze the exposed locking block, causing it to move inward until it tightens the bolt. It will not loosen due to long-term shaking of the vehicle and prevent the nut body from rotating during shaking. The fixing shell is pressed down until the inner surface of the fixing shell is inserted into the through hole on the surface of the nut body through a spring-connected insert rod, preventing the fixing shell from falling off. This greatly increases the locking stability of the device.

[0014] 2. This type of self-locking special-shaped fastening nut for automobiles features a washer fixedly connected to the bottom of the nut body, a sealing gasket fixedly connected to the surface of a sealing block, a sealing groove at the bottom of the sealing block, and a glue inlet fixedly connected to the top of the sealing block. When the nut body is tightened, the sealing gasket at the bottom of the sealing block will press against the flat surface, increasing the sealing performance. Then, waterproof glue is injected into the glue inlet until the sealing groove is filled. At this point, the connection between the nut body and the bolt will be fully isolated from the outside environment, preventing rainwater from entering the connection and causing rust when the vehicle is driving in rainy weather, thus affecting its service life.

[0026] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a self-locking, irregularly shaped fastening nut for vehicles.

[0027] like Figure 1-4 As shown, this utility model discloses a self-locking, irregularly shaped fastening nut for vehicles, comprising a nut body 1, a groove 2 on the surface of the nut body 1, a fixing shell 3 fitted onto the surface of the nut body 1, a through hole 4 on the surface of the nut body 1, a limiting groove 6 on the inner side of the groove 2, a locking block 5 inserted into the inner side of the groove 2, a sliding plate 7 fixedly connected to the surface of the locking block 5, the sliding plate 7 being within the limiting groove 6, the locking block 5 being fitted to the inner side of the fixing shell 3, and a spring-connected insertion rod 9 penetrating the fixing shell 3 and inserted into the through hole 4. Thus, when the nut body 1 is tightened, the locking block 5 slides outward within the groove 2. The locking block 5 will not slide out due to the limiting groove 6 opened in the slide groove 2, and only its inclined surface is exposed on the surface of the nut body 1, which will not affect the use of the nut body 1. Then the fixing shell 3 is sleeved on the surface of the nut body 1. During the downward movement, it will squeeze the exposed locking block 5, causing it to move inward until the bolt is tightened. It will not loosen due to the long-term shaking of the vehicle, and prevent the nut body 1 from rotating during the shaking. The fixing shell 3 will continue to be pressed down until the inner surface of the fixing shell 3 is inserted into the through hole 4 opened on the surface of the nut body 1 through the spring-connected insertion rod 9, preventing the fixing shell 3 from falling off, which greatly increases the locking stability of the device.

[0028] A washer 11 is fixedly connected to the bottom of the nut body 1. A sealing block 12 is fixedly connected to the surface of the washer 11. A sealing gasket 13 is fixedly connected to the surface of the sealing block 12. A sealing groove 14 is opened at the bottom of the sealing block 12. A glue inlet 15 is fixedly connected to the top of the sealing block 12. In this way, when the nut body 1 is tightened, the sealing gasket 13 at the bottom of the sealing block 12 will press against the plane to increase the sealing performance. Then, waterproof glue is injected into the glue inlet 15 until the waterproof glue fills the sealing groove 14. At this time, the connection between the nut body 1 and the bolt will be fully isolated from the outside world, preventing rainwater from entering the connection when the vehicle is driving in the rain, which will cause rust and affect its service life.

[0029] The surface of the fixed shell 3 is fixedly connected with six fixed tubes 8 and six insertion rods 9. The fixed tubes 8 increase the contact area between the insertion rods 9 and the fixed shell 3, prevent the insertion rods 9 from shaking, and increase the stability of the device.

[0030] A baffle 10 is fixedly connected to the surface of the nut body 1. The baffle 10 is distributed in a circular pattern. A reinforcing plate 18 is fixedly connected to the surface of the nut body 1. Thus, the reinforcing plate 18 is also fixedly connected to the surface of the nut body 1, which increases the compressive strength of the nut body 1.

[0031] The surface of the fixed shell 3 is fixedly connected with protrusions 17, which are distributed in a circular pattern. The protrusions 17 provide force points, and the fixed shell 3 can be made to slide down by tapping the protrusions 17. It can also be opened by tapping the protrusions 17 when it is taken out, which is quite convenient.

[0032] The bottom of the washer 11 is fixedly connected with an anti-slip ridge 16, which is distributed in a circular pattern. Thus, the bottom of the washer 11 at the bottom of the nut body 1 is also fixedly connected with an anti-slip ridge 16 with a bevel. The resistance is small when tightening normally, and when it is to be rotated in the opposite direction, its other side will clamp the plane to prevent it from rotating.

[0033] The working principle of this self-locking special-shaped fastening nut for vehicles is as follows: When the nut body 1 is tightened, the locking block 5 slides outward in the slide groove 2. Due to the limiting groove 6 in the slide groove 2, the locking block 5 will not slide out, and only its inclined surface is exposed on the surface of the nut body 1, thus not affecting the use of the nut body 1. Then, the fixing shell 3 is fitted onto the surface of the nut body 1. The fixing shell 3 can be slid down by tapping the protrusion 17, providing a force point. During the sliding process, it will squeeze the exposed locking block 5, causing it to move inward until it tightens the bolt, preventing it from loosening due to prolonged vehicle shaking and preventing the nut body 1 from rotating during shaking. The fixing shell 3 is then pressed down until the inner surface of the fixing shell 3 is inserted into the nut body 1 via a spring-connected insert rod 9. The inner side of the perforation 4 prevents the fixing shell 3 from falling off, greatly increasing the locking stability of the device. At the bottom of the washer 11 at the bottom of the nut body 1, there is also a fixed anti-slip ridge 16 with a bevel. The resistance is small when tightening normally. When turning in the opposite direction, the other side will clamp the plane to prevent it from turning. A reinforcing plate 18 is also fixedly connected to the surface of the nut body 1, which increases the compressive strength of the nut body 1. When tightening the nut body 1, the sealing gasket 13 at the bottom of the sealing block 12 will press the plane to increase the sealing performance. Then, waterproof glue is injected into the glue inlet 15 until the waterproof glue fills the sealing groove 14. At this time, the connection between the nut body 1 and the bolt will be fully isolated from the outside world, preventing rainwater from entering the connection when the vehicle is driving in the rain, which will cause rust and affect its service life.

[0034] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
