[0001] This utility model relates to the field of screw assembly technology, specifically to an integrated screw assembly with an anti-loosening washer. Background Technology

[0002] A screw is a fastening element that uses the interlocking of threads to generate pressure through rotation, thereby fixing two or more workpieces together. Its basic principle is based on inclined planes and rotational motion, achieving fastening through friction. Screws are widely used in manufacturing, construction, electronic equipment and many other fields. There are many specifications and models of screws, and users can choose the appropriate screw according to their own needs.

[0003] Some integrated screw assemblies also have some problems, such as the screws loosening after repeated use and when the equipment vibrates. The screw rod is also prone to accidental loosening during use, which can affect its use.

[0004] Therefore, we propose an integrated screw assembly with anti-loosening washers to improve upon the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide an integrated screw assembly with an anti-loosening washer to solve the problem mentioned in the background art where the screw rod is easily loosened accidentally during use, which can affect its use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated screw assembly with an anti-loosening washer, comprising a screw rod, a circular screw head at the top of the screw rod, a protrusion fixedly connected to the bottom of the circular screw head, a washer at the bottom of the protrusion, and a reserved groove at the bottom of the washer.

[0007] As a further technical solution of this utility model, the diameter inside the reserved groove is larger than the diameter outside the screw, and the gasket is sleeved on the top of the outside of the screw.

[0008] As a further technical solution of this utility model, the protrusion and the circular screw head are fixedly connected to the top of the screw rod, and the screw rod is machined with external threads.

[0009] As a further technical solution of this utility model, the bottom end of the gasket is movable at the top end outside the screw, and the bottom end of the screw is fixedly connected to a center.

[0010] As a further technical solution of this utility model, the outer surface of the circular screw head is machined with anti-slip texture, the top of the circular screw head is fixedly connected with a hexagonal screw head, the left and right sides of the top of the inner surface of the circular screw head are provided with mounting holes, the outer surface of the hexagonal screw head is provided with an anti-slip ring, and the middle position of the inner surface of the hexagonal screw head is machined with a cross mounting groove.

[0011] As a further technical solution of this utility model, the anti-slip texture is provided in multiple sets, and the anti-slip texture is distributed in a ring at equal intervals on the outside of the circular screw head.

[0012] As a further technical solution of this utility model, the screw and the tip are provided with a waterproof coating, the waterproof coating is processed with an electroplated layer, and the electroplated layer is coated with a corrosion-resistant coating.

[0013] As a further technical solution of this utility model, the electroplating layer is disposed between the waterproof coating and the corrosion-resistant coating, and the corrosion-resistant coating is a Teflon coating.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the integrated screw assembly with anti-loosening washer not only improves the anti-loosening effect and facilitates screw disassembly and assembly in multiple ways, but also improves the service life of the screw; By incorporating a washer, a protrusion, and a pre-drilled groove, the washer is installed at the top of the screw. Since the bottom of the washer has a pre-drilled groove and the bottom of the washer can slide at the top of the screw, the washer increases the friction between the screw and the mounting point when tightening the screw. This friction helps prevent the screw from loosening and falling off, thus affecting its use. By incorporating features such as round screw heads, anti-slip textures, hexagonal screw heads, mounting holes, anti-slip rings, and Phillips head mounting slots, the anti-slip textures on the outside of the round screw heads prevent accidental slippage when the round screw heads are clamped and rotated. Similarly, the anti-slip rings on the outside of the hexagonal screw heads also prevent accidental slippage. The anti-slip rings facilitate the use of a screwdriver to rotate the hexagonal screw heads and screw rods for installation and removal. The anti-slip textures, hexagonal screw heads, and Phillips head mounting slots increase the methods of installation and removal, thus facilitating the installation and removal of the screw rods. By incorporating a waterproof coating, an electroplated layer, and a corrosion-resistant coating, the waterproof coating prevents water from seeping into the screw's interior and affecting its service life. The electroplated layer and the corrosion-resistant coating protect the screw's surface, reducing corrosion and rust caused by prolonged use, thereby further extending the screw's service life.

[0017] 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.

[0018] Please see Figure 1-4 The present invention provides an embodiment of an integrated screw assembly with an anti-loosening washer, comprising a screw rod 1, a circular screw head 4 at the top of the screw rod 1, a protrusion 3 fixedly connected to the bottom of the circular screw head 4, a washer 2 at the bottom of the protrusion 3, and a reserved groove 7 at the bottom of the washer 2. The inner diameter of the reserved groove 7 is larger than the outer diameter of the screw 1. The washer 2 is fitted onto the top of the screw 1. The protrusion 3 and the round screw head 4 are fixedly connected to the top of the screw 1. The screw 1 has external threads machined on its outer side. The bottom end of the washer 2 is movable on the top of the screw 1. The bottom end of the screw 1 is fixedly connected to the center 8. Specifically, such as Figure 1 and Figure 4 As shown, the washer 2 is installed at the top of the outside of the screw 1. Since the bottom of the washer 2 has a reserved groove 7, and the bottom of the washer 2 can slide at the top of the outside of the screw 1, the washer 2 will increase the friction between the screw and the mounting point when the screw 1 is tightened. This friction can prevent the screw 1 from loosening and falling off, thus affecting the use of the screw 1.

[0019] The outer surface of the round screw head 4 is machined with anti-slip texture 5. The top of the round screw head 4 is fixedly connected to a hexagonal screw head 6. The left and right sides of the top of the round screw head 4 are provided with mounting holes 9. The outer surface of the hexagonal screw head 6 is provided with an anti-slip ring 10. The middle position of the inner surface of the hexagonal screw head 6 is machined with a cross mounting groove 11. Multiple sets of anti-slip texture 5 are provided. The anti-slip texture 5 is distributed in a ring at equal intervals on the outer surface of the round screw head 4. Specifically, such as Figure 1 and Figure 2 As shown, the anti-slip texture 5 on the outside of the round screw head 4 can prevent the round screw head 4 from accidentally sliding when it is clamped and rotated. Similarly, the anti-slip ring 10 on the outside of the hexagonal screw head 6 can also prevent the hexagonal screw head 6 from accidentally sliding. The anti-slip ring 10 can facilitate the installation and removal of the screw 1 by using a screwdriver to rotate the hexagonal screw head 6 and the screw rod 1. The anti-slip texture 5, the hexagonal screw head 6 and the cross mounting groove 11 can increase the ways of installation and removal, thereby facilitating the installation and removal of the screw rod 1.

[0020] The screw 1 and the tip 8 are provided with a waterproof coating 12. The waterproof coating 12 is processed with an electroplated layer 13. The electroplated layer 13 is coated with a corrosion-resistant coating 14. The electroplated layer 13 is disposed between the waterproof coating 12 and the corrosion-resistant coating 14. The corrosion-resistant coating 14 is a Teflon coating. Specifically, such as Figure 3 As shown, the waterproof coating 12 can prevent water from seeping into the interior of the screw 1 and affecting its service life. The electroplated layer 13 and the corrosion-resistant coating 14 can protect the surface of the screw 1 and reduce corrosion and rust caused by long-term use, thereby further increasing the service life of the screw 1.

[0021] Working principle: In use, the washer 2 is installed on the top of the screw 1. Because the bottom of the washer 2 has a pre-drilled groove 7, and the bottom of the washer 2 can slide on the top of the screw 1, tightening the screw 1 increases the friction between the screw and the mounting point. This friction prevents the screw 1 from loosening and falling off, thus affecting its use. The anti-slip texture 5 on the outside of the round screw head 4 prevents the round screw head 4 from accidentally sliding when it is clamped and rotated. Similarly, the anti-slip ring 10 on the outside of the hexagonal screw head 6 also prevents... If the hexagonal screw head 6 accidentally slips, the anti-slip ring 10 allows for easy installation and removal of the screw 1 by using a screwdriver to rotate the hexagonal screw head 6 and the screw 1. The anti-slip texture 5, hexagonal screw head 6, and Phillips head mounting slot 11 increase the ways to install and remove the screw 1, thus facilitating its installation and removal. The waterproof coating 12 prevents water from seeping into the screw 1 and affecting its service life. The electroplating layer 13 and corrosion-resistant coating 14 protect the surface of the screw 1, reducing corrosion and rust caused by prolonged use, thereby further increasing its service life.
