Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a nut used for automobile parts. Background Art

[0002] The automobile body assembly is mainly composed of stamped parts that are assembled into sub-assemblies through welding and bolts, and then the sub-assemblies are welded again to form the white body assembly.

[0003] The nut is installed on one of the two parts that need to be assembled, the bolt passes through the through holes on the two parts, and is tightened with the nut to achieve assembly; therefore, whether the installation position accuracy of the nut on the part is qualified directly affects the overall accuracy after assembly. When the nut is installed, its verticality, torque and wear will affect the quality of installation. Taking the car door as an example, the nut is installed on the door assembly. During assembly, the door assembly is installed on the body through hinges and bolts. Therefore, the welding position accuracy of the nut on the door assembly directly affects the assembly quality of the door. A high-precision car body can not only ensure the assembly accuracy of the final assembly parts, but is also an important factor affecting the body appearance gap and the quality of the whole vehicle.

[0004] In actual use, it is necessary to place the nut into the blind hole first and then tighten the bolt into the nut. At this time, during the installation process, it is necessary to hold the nut with one hand and tighten the bolt with the other hand. During the rotation process, the nut is very easy to fall out of the blind hole or be pushed out by the bolt and loosen, resulting in troublesome installation and low efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a nut for automobile spare parts, which can drive the sliding rod and the snapping piece to rotate by setting a return piece. The snapping piece is set as a half-pointed cone, so that the snapping piece can be rotated to the other half. When the user turns the button to drive the sliding rod and the snapping piece to rotate and rotate the snapping piece to the other half, the reinforcement body will be pulled back by the return piece without being subjected to the thrust, so that the reinforcement body can be returned to its original position. By utilizing the interference between multiple reinforcement bodies and blind holes (multiple reinforcement bodies can be set, and two are set in the figure), multiple interference forces can be applied in the circumferential direction of the gasket, thereby increasing the interference friction between the nut and the blind hole, obtaining a better locking force, and effectively preventing the nut from escaping from the blind hole, which can solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a nut for automobile spare parts, comprising an integrally formed hexagon and a gasket, the lower end face of the hexagon being fixedly provided with a gasket, the surface of the gasket being provided with two fixing grooves, a reinforcement body being provided inside the fixing groove, the gasket and the reinforcement body being slidably connected, the gasket being provided with an actuator for driving the reinforcement body to move in the radial direction of the gasket, and the reinforcement body being arranged to be in conflict with the blind hole at one end away from the actuator.

[0007] Preferably, the surface of the reinforcement body in contact with the blind hole is configured as a resistance-enhancing pad, and the actuator includes a sliding rod, a snap-fit ​​part and a button.

[0008] Preferably, two circular grooves are formed on the upper end surface of the gasket, a slide rod is disposed inside the circular groove, and a button is fixedly disposed at one end of the slide rod.

[0009] Preferably, a buckle is fixedly provided at the other end of the slide rod, and the buckle is configured as a half-conical shape without a sharp end.

[0010] Preferably, a through hole is formed on the lower end surface of the gasket, and a thread groove is formed on the inner surface of the hexagonal body.

[0011] Preferably, a fixing piece is fixedly provided on one side of the reinforcement body close to the center of the gasket, and a restoring piece is fixedly provided on one side of the reinforcement body close to the center of the gasket.

[0012] Preferably, the return member is configured as a spring, and the other end of the return member is mounted on the inner surface of the fixing groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model provides a return piece, and the user can rotate the button to drive the slide bar and the buckle piece to rotate. The buckle piece is set to be half a sharp cone, so that the buckle piece can be rotated to the other half. When the user rotates the button to drive the slide bar and the buckle piece to rotate and rotate the buckle piece to the other half, the reinforcement body will be pulled back by the return piece without being subjected to the thrust, so that the reinforcement body can be returned to its original position. By utilizing the interference between multiple reinforcement bodies and blind holes (multiple reinforcement bodies can be set, and two are set in the figure), multiple interference forces can be applied in the circumferential direction of the gasket, thereby increasing the interference friction between the nut and the blind hole, obtaining a better locking force, and effectively preventing the nut from falling out of the blind hole.

[0021] 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 of 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.

[0022] Example 1

[0023] See also Figure 5 The figure shows a nut for automobile spare parts, including an integrally formed hexagonal body 1 and a gasket 2. The gasket 2 is fixedly arranged on the lower end surface of the hexagonal body 1. Two fixing grooves 8 are provided on the surface of the gasket 2. A reinforcing body 5 is arranged inside the fixing groove 8. The gasket 2 and the reinforcing body 5 are slidably connected. The gasket 2 is provided with an actuator for driving the reinforcing body 5 to move along the radial direction of the gasket 2. The end of the reinforcing body 5 away from the actuator is arranged to be in conflict with the blind hole 4.

[0024] See also Figure 2 In the figure, the surface of the reinforcement body 5 that contacts the blind hole 4 is set as a resistance-increasing pad 6, and the actuator includes a slide rod 9, a snap-fit ​​part 11 and a button 10.

[0025] In this embodiment, the provision of the resistance-increasing pad 6 can increase the surface friction between the reinforcement body 5 and the blind hole 4 , so that the reinforcement body 5 will not be easily separated from the blind hole 4 .

[0026] Working principle: A through hole 14 is provided on the lower end surface of the gasket 2, and a thread groove 3 is provided on the inner surface of the hexagonal body 1 to form a nut. Figure 5As shown, when the nut is placed in the blind hole 4, the actuator can be installed by opening the circular groove 7, and the actuator includes a slide bar 9, a buckle 11 and a button 10. When the user presses the button 10, the slide bar 9 and the buckle 11 can be driven to move downward. The downward movement of the buckle 11 will squeeze the reinforcing body 5. The embedding effect of the buckle 11 and the fixing member 13 can be utilized to push the fixing member 13 out, and the position of the reinforcing body 5 can be fixed. The moving distance of the reinforcing body 5 can also be adjusted, thereby increasing the resistance between the reinforcing body 5 and the blind hole 4, preventing the reinforcing body 5 from being separated from the blind hole 4, and playing a limiting role on the reinforcing body 5, so that the reinforcing body 5 will not return to its original position, and the outer side of the reinforcing body 5 can be adjusted. The end face and the blind hole 4 are set in a resistance manner. By utilizing the resistance between multiple reinforcement bodies 5 and the blind hole 4 (multiple reinforcement bodies 5 can be set, and two are set in the figure), multiple resistance forces can be applied in the circumferential direction of the gasket 2, thereby increasing the resistance friction between the nut and the blind hole 4, obtaining a better locking force, and effectively preventing the nut from escaping from the blind hole 4; when the nut needs to be removed, by setting a return member 12, when the user turns the button 10, driving the slide rod 9 and the snap member 11 to rotate and rotating the snap member 11 to the other half, the reinforcement body 5 will be pulled back by the return member 12 without being subjected to the thrust, so that the reinforcement body 5 can be returned to its position, thereby enabling the nut to be smoothly removed from the blind hole 4.

[0028] See also Figure 3 The present embodiment further illustrates the first embodiment. In the figure, the upper end surface of the gasket 2 is provided with two circular grooves 7, a slide bar 9 is provided inside the circular groove 7, and a button 10 is fixedly provided at one end of the slide bar 9.

[0029] In this embodiment: the actuator can be installed by providing the circular groove 7. When the user presses the button 10, the slide bar 9 and the latch 11 can be driven to move downward. The downward movement of the latch 11 will squeeze the reinforcement 5, thereby pushing the fixing member 13 out.

[0030] See also Figure 4 In the figure, a snap-fit ​​member 11 is fixedly provided at the other end of the slide rod 9, and the snap-fit ​​member 11 is set to be half a blunt cone.

[0031] In this embodiment, the user rotates the button 10 to drive the slide bar 9 and the buckle 11 to rotate. The buckle 11 is configured as a half-pointed cone, so that the buckle 11 can be rotated to the other half.

[0032] See also Figure 1 In the figure, a through hole 14 is provided on the lower end surface of the gasket 2, and a thread groove 3 is provided on the inner surface of the hexagonal body 1.

[0033] In this embodiment: a through hole 14 is provided on the lower end surface of the gasket 2, and a thread groove 3 is provided on the inner surface of the hexagonal body 1 to form a nut.

[0034] See also Figure 3 In the figure, a fixing member 13 is fixedly provided on one side of the reinforcing body 5 close to the center of the gasket 2, and a restoring member 12 is fixedly provided on one side of the reinforcing body 5 close to the center of the gasket 2.

[0035] In this embodiment: by utilizing the interference effect between multiple reinforcement bodies 5 and blind holes 4 (multiple reinforcement bodies 5 can be provided, and two are provided in the figure), multiple interference forces can be applied in the circumferential direction of the gasket 2, thereby increasing the interference friction between the nut and the blind hole 4, obtaining a better locking force, and effectively preventing the nut from escaping from the blind hole 4. By providing a return member 12, when the user turns the button 10, driving the slide rod 9 and the snap member 11 to rotate and rotating the snap member 11 to the other half, the reinforcement body 5 will be pulled back by the return member 12 without being subjected to the thrust, thereby achieving the return of the reinforcement body 5.

[0036] See also Figure 4 In the figure, the return member 12 is configured as a spring, and the other end of the return member 12 is installed on the inner surface of the fixing groove 8.

[0037] In this embodiment, the position of the reinforcing body 5 can be fixed by utilizing the embedding effect of the snap member 11 and the fixing member 13, and the moving distance of the reinforcing body 5 can also be adjusted, thereby increasing the resistance between the reinforcing body 5 and the blind hole 4, preventing the reinforcing body 5 from being separated from the blind hole 4, and limiting the reinforcing body 5 so that the reinforcing body 5 will not return to its original position. The reinforcing body 5 can be returned to its original position by rotating the button 10.
