Description

Technical Field

[0001] This utility model belongs to the field of irregular nut technology, and in particular relates to an irregular nut for vehicles with a detachable structure. Background Technology

[0002] Automotive detachable nuts are specially designed fasteners that combine the structural features of detachable nuts with a detachable function to meet the needs of specific applications such as automobiles. These nuts typically have non-standard shapes to adapt to complex installation environments and are designed with a detachable structure, allowing the nuts to be easily separated or disassembled when needed.

[0003] Currently available automotive nuts with a split design have the following problems when used:

[0004] Traditional automotive nuts with detachable structures require many turns to remove when a car needs to be disassembled for repair or parts replacement, which is cumbersome. In addition, there are usually many bolts on a car, and repeated operations reduce the work efficiency of the staff. Utility Model Content

[0005] The purpose of this utility model is to provide a special-shaped nut for vehicles with a detachable structure, so as 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 special-shaped nut for vehicles with a separable structure includes a first half-nut and a second half-nut. A plug is fixedly connected to the surface of the first half-nut, and a second insertion hole is formed on the surface of the plug. A slot is formed on the surface of the second half-nut, and a first insertion hole is formed on the surface of the second half-nut. The plug is inserted into the inner side of the slot, and a threaded hole is formed at the bottom of the slot. A connecting cover is sleeved on the surface of the first half-nut and the second half-nut. A plug rod is connected to the surface of the connecting cover through a bearing. A threaded rod is fixedly connected to the bottom of the plug rod. The plug rod penetrates the first insertion hole and the second insertion hole. The surface of the threaded rod is connected to the threaded hole through a thread. Thus, when it is necessary to disassemble the nut, simply rotate the plug rod connected to the connecting cover through the bearing to disengage the threaded rod from the threaded hole on the second half-nut. Then, pinch the protrusion fixedly connected to the surface of the connecting cover by hand to disengage the connecting cover from the first half-nut and the second half-nut. At this time, the plug rod will also disengage from the slot and the first and second insertion holes on the plug, allowing the first half-nut and the second half-nut to be directly removed from the bolt for easy disassembly.

[0007] Preferably, a drying box is fixedly connected to the surface of the connecting cover, and a drying bag is provided inside the drying box. A sealing groove is opened inside the first half nut, and a sealing ring is provided in the sealing groove. In this way, when the special-shaped nut is tightened, the sealing rings provided inside the first and second half nuts will form a tight contact with the bolt surface, forming a sealed space. The drying bag provided in the drying box will absorb the moisture in the sealed space to prevent the connection from rusting, which increases the protection of the device. Moreover, the sealing ring in the sealing groove can be replaced repeatedly without affecting the sealing performance.

[0008] Preferably, a baffle is fixedly connected to the surface of the first half nut, and an elastic ball is fixedly connected to the inner side of the baffle. A groove is formed on the surface of the connecting cover, and the elastic ball is inserted into the inner side of the groove. Thus, the elastic ball fixedly connected to the baffle surface is also inserted into the groove inside the connecting cover, thereby enhancing stability and preventing the connecting cover from falling off.

[0009] Preferably, the surface of the connecting cover is fixedly connected with protrusions, which are distributed in a rectangular shape. The protrusions increase the stress points and facilitate the removal of the connecting cover.

[0010] Preferably, a fixing sleeve is fixedly connected to the surface of the connecting cover, and an anti-loosening bolt is threadedly connected to the inner side of the fixing sleeve. The surface of the anti-loosening bolt penetrates the first half nut. Tightening the anti-loosening bolt compresses the bolt, preventing the nut from rotating and increasing the stability of the device.

[0011] Preferably, the surface of the first half nut is fixedly connected with an anti-slip strip, which is distributed in a circular pattern. Thus, the resistance is small when tightening normally due to the anti-slip protrusions, 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 special-shaped nut with a detachable structure for vehicles according to this utility model has the following advantages:

[0013] 1. A special-shaped nut for vehicles with a detachable structure, wherein a second insertion hole is formed on the surface of a plug fixedly connected to the surface of a first half-nut, and the plug is inserted into a slot formed on the surface of a second half-nut. The second half-nut has a first insertion hole, and a threaded hole is formed at the bottom of the slot. A connecting cover is fitted onto the first and second half-nuts. At this time, the surface of the connecting cover is connected by a bearing, and the plug rod penetrates the first and second insertion holes. The bottom of the plug rod is fixedly connected to a threaded rod, which is connected to a threaded hole. Thus, when it is necessary to disassemble the nut, simply rotate the plug rod connected to the connecting cover by the bearing, so that the threaded rod disengages from the threaded hole on the second half-nut. Then, by pinching the protrusion fixedly connected to the surface of the connecting cover, the connecting cover can be disengaged from the first and second half-nuts. At this time, the plug rod will also disengage from the slot and the first and second insertion holes on the plug, so that the first and second half-nuts can be directly removed from the bolt for easy disassembly.

[0014] 2. This type of automotive nut with a detachable structure features a desiccant pack fixedly connected to the surface of the connecting cover, and a sealing groove with a sealing ring inside the first half-nut. When the nut is tightened, the sealing rings inside the first and second half-nuts form a tight contact with the bolt surface, creating a sealed space. The desiccant pack inside the desiccant pack absorbs moisture in the sealed space, preventing rust at the connection point. This increases the protective properties of the device, and the sealing rings in the sealing groove can be replaced repeatedly without affecting the sealing performance. Attached Figure Description

[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 special-shaped nut for vehicles with a separable structure.

[0027] like Figure 1-4 As shown, this utility model discloses a special-shaped nut for vehicles with a detachable structure, comprising a first half-nut 1 and a second half-nut 2. A plug 4 is fixedly connected to the surface of the first half-nut 1, and a second insertion hole 5 is formed on the surface of the plug 4. A slot 3 is formed on the surface of the second half-nut 2, and a first insertion hole 6 is formed on the surface of the second half-nut 2. The plug 4 is inserted into the inner side of the slot 3, and a threaded hole 8 is formed at the bottom of the slot 3. A connecting cover 7 is sleeved on the surfaces of the first half-nut 1 and the second half-nut 2. A plug rod 9 is connected to the surface of the connecting cover 7 via a bearing. A threaded rod 10 is fixedly connected to the bottom of the plug rod 9, and the plug rod 9 penetrates the first half-nut 1. The insertion hole 6 and the second insertion hole 5 are connected to the threaded hole 8 on the surface of the threaded rod 10. When it is necessary to disassemble the nut, simply rotate the insertion rod 9 connected to the bearing on the surface of the connecting cover 7 to disengage the threaded rod 10 from the threaded hole 8 on the second half nut 2. Then, pinch the protrusion 17 fixedly connected to the surface of the connecting cover 7 to disengage the connecting cover 7 from the first half nut 1 and the second half nut 2. At this time, the insertion rod 9 will also disengage from the first insertion hole 6 and the second insertion hole 5 on the slot 3 and the insertion block 4, so that the first half nut 1 and the second half nut 2 can be directly removed from the bolt for easy disassembly.

[0028] A drying box 13 is fixedly connected to the surface of the connecting cover 7. A drying bag 14 is provided inside the drying box 13. A sealing groove 15 is provided inside the first half nut 1. A sealing ring 16 is provided inside the sealing groove 15. When the special-shaped nut is tightened, the sealing ring 16 provided inside the first half nut 1 and the second half nut 2 will form a tight contact with the bolt surface to form a sealed space. The drying bag 14 provided inside the drying box 13 will absorb the moisture in the sealed space to prevent the connection from rusting, which increases the protection of the device. The sealing ring 16 in the sealing groove 15 can be replaced repeatedly without affecting the sealing performance.

[0029] A baffle 11 is fixedly connected to the surface of the first half nut 1, and an elastic ball 12 is fixedly connected to the inner side of the baffle 11. A groove 21 is opened on the surface of the connecting cover 7, and the elastic ball 12 is inserted into the inner side of the groove 21. Thus, the elastic ball 12 fixedly connected to the surface of the baffle 11 is also inserted into the groove 21 in the connecting cover 7, thereby enhancing stability and preventing the connecting cover 7 from falling off.

[0030] The surface of the connecting cover 7 is fixedly connected with a protrusion 17, which is distributed in a rectangular shape. The protrusion 17 increases the force points and makes it easier to remove the connecting cover 7.

[0031] A fixing sleeve 18 is fixedly connected to the surface of the connecting cover 7. An anti-loosening bolt 19 is threadedly connected to the inside of the fixing sleeve 18. The surface of the anti-loosening bolt 19 penetrates the first half nut 1. Tightening the anti-loosening bolt 19 presses the bolt together, preventing the nut from rotating and increasing the stability of the device.

[0032] The surface of the first half nut 1 is fixedly connected with anti-slip strips 20, which are distributed in a circular pattern. Thus, through the anti-slip protrusions 17, the resistance is small when tightening normally, and when it is to be rotated in the opposite direction, the other side will clamp the plane to prevent it from rotating.

[0033] The working principle of this automotive-grade nut with a detachable structure is as follows: First, the insert block 4, fixedly connected to the surface of the first half-nut 1, is inserted into the slot 3 on the surface of the second half-nut 2. Then, the connecting cover 7 is fitted onto the surfaces of the first half-nut 1 and the second half-nut 2. The insert rod 9 is then inserted into the first insertion hole 6 and the second insertion hole 5 on the surfaces of the first half-nut 1 and the insert block 4, until the threaded rod 10 at the bottom of the insert rod 9 contacts the threaded hole 8 inside the slot 3. By rotating the insert rod 9, the threaded rod 10 is screwed into the threaded hole 8 to prevent the connecting cover 7 from falling off. At this time, the groove 21 inside the connecting cover 7 also inserts into the elastic ball 12 fixedly connected to the surface of the baffle 11, enhancing stability and preventing the connecting cover 7 from falling off. The connecting cover 7 and the insert rod 9 ensure a tight fit between the first half-nut 1 and the second half-nut 2, preventing separation. Furthermore, the baffle 11 fixedly connected to the surfaces of the first half-nut 1 and the second half-nut 2 presses down on the connecting cover 7, preventing it from deforming due to excessive force, thus increasing the protection of the device. Then, tighten the anti-loosening bolt 19 to press the bolt, preventing the nut from rotating and increasing the stability of the device. When it is necessary to disassemble the nut, simply rotate the insert rod 9 connected to the bearing on the surface of the connecting cover 7, so that the threaded rod 10 disengages from the threaded hole 8 on the second half nut 2. Then, pinch the protrusion 17 fixedly connected to the surface of the connecting cover 7 by hand to disengage the connecting cover 7 from the first half nut 1 and the second half nut 2. At this time, the insert rod 9 will also disengage from the first insertion hole 6 and the second insertion hole 5 on the slot 3 and the insert block 4, so that the first half nut 1 and the second half nut 2 can be directly removed from the bolt for easy disassembly. In addition, the sealing ring 16 provided inside the first half nut 1 and the second half nut 2 will form a tight contact with the bolt surface to form a sealed space. The desiccant 14 provided in the drying box 13 will absorb the moisture in the sealed space to prevent the connection from rusting, increasing the protection of the device. The sealing ring 16 in the sealing groove 15 can be replaced repeatedly without affecting the sealing performance.
