Description

Technical Field

[0001] This utility model relates to the field of screw equipment technology, specifically to a screw for assembling automotive parts. Background Technology

[0002] As critical fasteners, screws play a vital role in automobile manufacturing and operation. Screws tightly connect various automotive components, forming a complete vehicle structure. They also secure structural parts such as the body frame, doors, and roof, ensuring the rigidity and stability of the vehicle body. During vehicle operation, the body is subjected to various forces, and the tightening of screws prevents body parts from loosening or deforming.

[0003] For example, the utility model patent disclosed in publication number CN209724921U discloses a special screw for automobiles, comprising: a main body, the main body having a screw head, a reinforcing disc, a first rod, and a second rod, the screw head, reinforcing disc, first rod, and second rod being formed and fixed from top to bottom; the lower end of the second rod having external threads; the reinforcing disc, first rod, and second rod are all cylindrical in shape, the radius of the reinforcing disc being larger than the radius of the first rod, and the radius of the first rod being larger than the radius of the second rod; the lower surface of the reinforcing disc having a first lead-tin alloy layer, and the lower surface of the first rod having a second lead-tin alloy layer. This special screw for automobiles not only has good compressive strength, but also has a low coefficient of friction on its lower surface, providing good anti-friction capability and effectively preventing loosening due to wear.

[0004] Although the aforementioned automotive screws have a certain degree of wear resistance, the support stability and protective performance of the anti-slip pads at the bottom of the screws are still insufficient. At the same time, the aforementioned automotive screws also lack sufficient protection for the hexagonal grooves, which reduces the service life of the screws and the ease of subsequent disassembly. Therefore, there is an urgent need for a new type of automotive parts screw to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a screw for assembling automotive parts to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a screw for automotive parts, comprising a screw turntable for support, a threaded guide groove at the center of the upper end face of the screw turntable, and an internal hexagonal socket at the center of the inner end face of the threaded guide groove, and six sets of positioning slots equidistantly provided at the bottom of the internal hexagonal socket.

[0007] The external hexagonal slot is located on the outer end face of the screw turntable near the bottom. A threaded bolt is fixedly installed at the center of the lower end face of the screw turntable. A fixing slot is provided on the lower end face of the screw turntable near the outside.

[0008] An anti-slip device is fixedly mounted on the lower end face of the screw turntable via the fixing slot. The anti-slip device is used for anti-slip and limiting.

[0009] A sealing device is provided, wherein the sealing device is threadedly connected to the upper end face of the screw turntable via the threaded guide groove, and the sealing device is used for sealing and protection.

[0010] Preferably, the sealing device includes a sealing chuck, a threaded shaft is fixedly provided at the center of the lower end face of the sealing chuck, and a hexagonal guide groove is provided at the center of the upper end face of the sealing chuck.

[0011] Preferably, the anti-slip device includes a fixing ring, six sets of elastic pads are equidistantly arranged on the lower end face of the fixing ring, and a wear-resistant protective sheet is fixedly arranged at the center of the lower end face of the elastic pads. Anti-slip protrusions are equidistantly arranged on the lower end face of the wear-resistant protective sheet, and a reinforcing ring is fixedly arranged inside the six sets of elastic pads.

[0012] Preferably, the sealing chuck is threadedly connected to the upper end face of the screw turntable by means of the threaded shaft and the threaded guide groove, which can effectively improve the stability of the sealing chuck on the upper part of the screw turntable and thus improve the protection performance of the upper part of the screw turntable.

[0013] Preferably, the elastic gasket is L-shaped, and the fixing ring is fixedly disposed on the lower end face of the screw turntable through the fixing groove. The L-shaped elastic gasket can undergo elastic deformation when subjected to a large external force, thereby enabling the wear-resistant protective sheet to further increase the adhesion and friction with the workpiece surface.

[0014] Preferably, the wear-resistant protective sheet is made of rubber, which can effectively increase the friction with the workpiece surface, thereby reducing the relative slippage of the screw turntable.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting up a sealing device and an anti-slip device, and the elastic gasket is L-shaped, can facilitate the screw turntable to lock the outside of the workpiece. The elastic gasket can provide sufficient support elasticity, so that the wear-resistant protective plate can maximize the pressure and friction of contact with the outside of the workpiece, thereby reducing the relative sliding between the screw turntable and the locked workpiece and improving the stability of locking. At the same time, the six sets of elastic gaskets and the reinforcing ring can further improve the stability of the elastic gasket when supporting. The threaded seal between the sealing chuck and the upper part of the screw turntable can improve the protection of the upper part of the screw turntable and increase the service life of the screw. The internal hexagonal slot, the positioning slot and the external hexagonal slot can also provide different types of disassembly methods for the screw and nut, improving the convenience of subsequent disassembly.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5This utility model provides an embodiment of an automotive parts assembly screw, comprising a screw turntable 8 for support, a threaded guide groove 3 located at the center of the upper end face of the screw turntable 8, and an internal hexagonal socket 1 located at the center of the inner end face of the threaded guide groove 3, and six sets of positioning slots 4 equidistantly located at the bottom of the internal hexagonal socket 1.

[0025] The external hexagonal slot 5 is located on the outer end face of the screw turntable 8 near the bottom. A threaded bolt 7 is fixedly installed at the center of the lower end face of the screw turntable 8. A fixing slot 9 is provided on the lower end face of the screw turntable 8 near the outside.

[0026] Anti-slip device 6 is fixedly installed on the lower end face of screw turntable 8 through fixing slot 9. Anti-slip device 6 is used for anti-slip and limiting.

[0027] The sealing device 2 is connected to the upper end face of the screw turntable 8 through the threaded guide groove 3 for sealing and protection.

[0028] The sealing device 2 includes a sealing chuck 22, a threaded shaft 23 is fixedly provided at the center of the lower end face of the sealing chuck 22, and a hexagonal guide groove 21 is provided at the center of the upper end face of the sealing chuck 22.

[0029] The anti-slip device 6 includes a fixing ring 63. Six sets of elastic pads 65 are equidistantly arranged on the lower end face of the fixing ring 63. A wear-resistant protective sheet 61 is fixedly arranged at the center of the lower end face of the elastic pads 65. Anti-slip protrusions 62 are equidistantly arranged on the lower end face of the wear-resistant protective sheet 61. A reinforcing ring 64 is fixedly arranged inside the six sets of elastic pads 65.

[0030] The sealing chuck 22 is threadedly connected to the upper end face of the screw turntable 8 by the threaded shaft 23 and the threaded guide groove 3, which can effectively improve the stability of the sealing chuck 22 sealing the upper part of the screw turntable 8, thereby improving the protection performance of the upper part of the screw turntable 8.

[0031] The elastic pad 65 is L-shaped, and the fixing ring 63 is fixedly mounted on the lower end face of the screw turntable 8 through the fixing groove 9. The L-shaped elastic pad 65 can undergo elastic deformation when subjected to a large external force, thereby enabling the wear-resistant protective sheet 61 to further increase the adhesion and friction with the workpiece surface.

[0032] The wear-resistant protective plate 61 is made of rubber, which can effectively increase the friction with the workpiece surface, thereby reducing the relative slippage of the screw turntable 8.

[0033] Working principle: During use, the operator can insert the threaded bolt 7 through the automotive workpiece, then position the external nut at the bottom of the workpiece, and then use a tool to thread-lock the nut and threaded bolt 7 onto the workpiece. During locking, the wear-resistant protective plate 61 and the elastic washer 65 can contact and press against the upper surface of the workpiece. As the threaded connection tightens, the elastic washer 65 can undergo elastic deformation. At the same time, the wear-resistant protective plate 61 and the anti-slip protrusion 62 can further conform to the surface of the workpiece, minimizing the loosening of the area where the screw turntable 8 locks the workpiece. After locking, the user can connect the sealing chuck 22 to the threaded guide groove 3 through the threaded shaft 23, thereby sealing and locking it on the upper part of the screw turntable 8, preventing the threaded guide groove 3 and the internal hexagonal socket 1 inside the screw turntable 8 from being corroded. At the same time, when the internal hexagonal socket 1 deforms under the action of the tool, the positioning slot 4 and the external hexagonal socket 5 can provide sufficient limiting basis for the subsequent separation of the threaded bolt 7 and the nut.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
