Description

Technical Field

[0001] This utility model relates to the field of nut technology, and in particular to a wear-resistant automotive nut. Background Technology

[0002] Most existing nuts are hexagonal, and during installation, a wrench is generally required to attach them to the bolt. An existing patent (publication number: CN221170322U) discloses a wear-resistant nut. In this invention, the nut body and the wear-resistant layer are detachably connected by several sets of fixing components, making installation and disassembly simple and facilitating replacement of the wear-resistant layer to restore its wear resistance. However, in practical applications, because the lifting block in the above-mentioned technical solution protrudes from the surface of the nut's wear-resistant layer, it is prone to friction with the lifting block when turning the nut with tools such as wrenches, leading to damage to the lifting block, making it difficult to control the operating lever, and inconvenient to use. Therefore, we propose a wear-resistant automotive nut. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a wear-resistant automotive nut.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] Design a wear-resistant automotive nut, including a wear-resistant sleeve disposed on the outside of the nut body. The nut body has a threaded hole at its center. The nut body and the wear-resistant sleeve are assembled together and connected by an installation component. The installation component includes a mounting groove on the inner wall of the wear-resistant sleeve. A connecting frame is slidably disposed in the mounting groove. A pair of locking arms are hinged in the connecting frame. A locking groove is provided on the outer wall of the nut body to magnetically connect with the locking arms. A push rod is fixed to the side of the connecting frame away from the locking arms, penetrating the wear-resistant sleeve. A lifting handle is fixed to the end of the push rod. A storage groove for accommodating the lifting handle is provided on the surface of the wear-resistant sleeve.

[0006] In the above scheme, a positioning block is fixed on the inner wall of the wear-resistant sleeve of the nut, and a positioning groove that fits the positioning block is opened on the nut body.

[0007] In the above scheme, a reinforcing block is fixed at the corner of the wear-resistant sleeve of the nut.

[0008] In the above scheme, a splicing block is fixed on the back of the reinforcing block, and a splicing groove that fits the splicing block is opened at the corner of the wear-resistant sleeve of the nut.

[0009] In the above scheme, the locking arm is a magnetic metal locking arm, and a magnetic block is fixed to the inner wall of the locking groove.

[0010] In the above scheme, the connecting frame is fixed with sliders at both ends, the inner wall of the mounting groove is provided with a sliding groove that matches the slider, and a return spring is connected between the inner wall of the mounting groove away from the locking arm and the connecting frame.

[0011] In the above scheme, the surface of the lifting handle is coated with a magnetic coating.

[0012] In the above solution, a connecting groove is provided on the lifting handle, and a positioning ring is fixed in the connecting groove.

[0013] The advantages and beneficial effects of this utility model are as follows: By setting up a nut body, a nut wear-resistant sleeve, and an installation component, and by controlling the lifting handle, the push rod moves in and out of the installation groove, driving the connecting frame to move left and right, thereby causing the locking arm to disengage from the locking groove and move into the installation groove. Compared with the prior art, this makes it easier to replace severely worn nut wear-resistant sleeves and is more convenient to use. In addition, by using the storage groove, the lifting handle is placed in it, preventing the lifting handle from protruding from the surface of the nut wear-resistant sleeve and avoiding damage from contact between the lifting handle and the wrench. By setting up a reinforcing block, the wear resistance at the corners of the nut wear-resistant sleeve is improved, the wear degree of the nut wear-resistant sleeve is reduced, and the service life is extended, so that a wrench can be used for subsequent disassembly and replacement operations.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a wear-resistant automotive nut, including a wear-resistant sleeve 2 disposed on the outside of the nut body 1, a threaded hole 3 opened in the center of the nut body 1, and the nut body 1 and the wear-resistant sleeve 2 being assembled together;

[0022] Furthermore, a positioning block 4 is fixed on the inner wall of the nut wear-resistant sleeve 2, and a positioning groove 5 that fits with the positioning block 4 is provided on the nut body 1. The fit between the positioning block 4 and the positioning groove 5 facilitates the assembly of the nut wear-resistant sleeve 2 and the nut body 1.

[0023] Furthermore, the nut body 1 and the nut wear-resistant sleeve 2 are connected by the mounting assembly 9. The mounting assembly 9 includes a mounting groove 901 opened in the inner wall of the nut wear-resistant sleeve 2, a connecting frame 903 is slidably provided in the mounting groove 901, a pair of locking arms 904 are hinged in the connecting frame 903, and a locking groove 905 is opened on the outer wall of the nut body 1 to magnetically connect with the locking arms 904.

[0024] Furthermore, the locking arm 904 is a magnetic metal locking arm, and a magnetic block 906 is fixed to the inner wall of the locking groove 905; the locking arm 904 and the inner wall of the locking groove 905 are attracted to each other by magnetic attraction.

[0025] Furthermore, the connecting frame 903 has sliders 907 fixed at both ends, and the inner wall of the mounting groove 901 has a sliding groove 908 that matches the sliders 907. A return spring 909 is connected between the inner wall of the mounting groove 901 on the side away from the locking arm 904 and the connecting frame 903.

[0026] Specifically, such as Figure 3As shown, at this time, the return spring 909 is in a compressed state. When the connecting bracket 903 moves away from the locking groove 905, the compression of the return spring 909 is aggravated. When the connecting bracket 903 loses the external force, it will return to the position shown in the figure under the elastic force of the return spring 909, thereby locking the locking arm 904 and the locking groove 905.

[0027] A push rod 902 that penetrates the wear-resistant sleeve 2 of the nut is fixed on the side of the connecting bracket 903 away from the locking arm 904. A lifting handle 910 is fixed at the end of the push rod 902. A storage groove 913 that can accommodate the lifting handle 910 is opened on the surface of the wear-resistant sleeve 2. A guide groove is also provided in the wear-resistant sleeve 2 between the storage groove 913 and the mounting groove 901. The guide groove cooperates with the push rod 902 and is connected to the storage groove 913 and the mounting groove 901.

[0028] Specifically, by setting up the nut body 1, the nut wear-resistant sleeve 2, and the mounting component 9, and by controlling the lifting handle 910, the push rod 902 moves in and out of the mounting groove 901, driving the connecting frame 903 to move left and right, thereby causing the locking arm 904 to disengage from the locking groove 905 and move into the mounting groove 901. Compared with the prior art, this makes it easier to replace the severely worn nut wear-resistant sleeve 2, and is more convenient to use. In addition, by using the storage groove 913, the lifting handle 910 is placed in it, preventing the lifting handle 910 from protruding from the surface of the nut wear-resistant sleeve 2 and avoiding contact between the lifting handle 910 and the wrench, thus preventing damage.

[0029] Furthermore, in the first case, the surface of the lifting handle 910 is coated with a magnetic coating; the movement of the lifting handle 910 can be controlled by a magnet with a magnetism opposite to that of the magnetic coating, making it convenient to use.

[0030] Furthermore, in the second scenario, a connecting groove 911 is provided on the lifting handle 910, and a positioning ring 912 is fixed inside the connecting groove 911; by hooking the positioning ring 912, the lifting handle 910 can be moved for convenient use.

[0031] Specifically, the two design options for the 910 lifting handle can be selected according to the actual situation.

[0032] Furthermore, each corner of the nut wear-resistant sleeve 2 is fixed with a reinforcing block 6, which is made of tungsten-cobalt alloy. The nut wear-resistant sleeve 2 is made of wear-resistant stainless steel. Since wrenches typically clamp the corners of the nut wear-resistant sleeve 2, the reinforcing blocks 6 further enhance the wear resistance of the corners of the nut wear-resistant sleeve 2.

[0033] Furthermore, a splicing block 7 is fixed to the back of the reinforcing block 6, and a splicing groove 8 that fits the splicing block 7 is provided at the corner of the nut wear-resistant sleeve 2. The reinforcing block 6 and the nut wear-resistant sleeve 2 are welded together. The splicing block 7 and the splicing groove 8 are used to increase the contact area between the reinforcing block 6 and the nut wear-resistant sleeve 2 and improve the tightness of the connection between the two.

[0034] Specifically, by setting the reinforcing block 6, the wear resistance at the corner of the nut wear sleeve 2 is improved, the wear of the nut wear sleeve 2 is reduced, and the service life is extended, so that a wrench can be used for disassembly and replacement operations later.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
