Description

Technical Field

[0001] The utility model relates to the technical field of nuts, and in particular to a flange nut with good wear resistance. Background Art

[0002] A nut is a part that is screwed together with a bolt or screw for fastening. It is a component that must be used in all manufacturing machinery. According to the different materials, it is divided into several major types, such as carbon steel, stainless steel, non-ferrous metals (such as copper), etc.

[0003] Nuts are parts that tightly connect mechanical equipment. Nuts and bolts of the same specifications can be connected together through the inner thread. For example, M4-P0.7 nuts can only be connected with M4-P0.7 series bolts (in nuts, M4 refers to the inner diameter of the nut is about 4mm, and 0.7 refers to the distance between two thread teeth is 0.7mm); the same is true for American products, for example, 1 / 4-20 nuts can only be matched with 1 / 4-20 screws (1 / 4 refers to the inner diameter of the nut is about 0.25 inches, and 20 refers to 20 teeth in every inch). They can be divided into self-locking nuts, anti-loosening nuts, locking nuts, four-claw nuts, screw-in nut insurance nuts, thin-rod screw connection nuts, self-locking hexagonal cap nuts, special nuts for anchor screws, hexagonal crown thin nuts, and eye nuts. They are easy to install, do not require washers, are easy to disassemble, are reusable, are made of medium carbon steel, and can be used with grade 8.8, grade 10.9 and other high-strength bolts.

[0004] The nut needs to be screwed during use, and the bottom of the nut contacts the plane to generate friction, which fixes the nut and achieves a locking effect. However, when vibration occurs, the friction of the bottom of the nut alone is not enough to fix the bolt, which is prone to loosening. Loosening will create gaps, leading to internal corrosion and the risk of falling off. In view of this, a flange nut with good wear resistance is developed. Utility Model Content

[0005] The utility model provides a flange nut with good wear resistance, which solves the problem that when vibration occurs, the friction force of the bottom surface of the nut is insufficient to fix the bolt, which is easy to loosen, and the loosening will cause gaps, leading to internal corrosion and the risk of falling off.

[0006] The technical solution of the utility model is as follows:

[0007] A hexagonal nut, the bottom of which is connected with a flange;

[0008] A one-way fixing component, wherein the one-way fixing component is arranged at the bottom of the flange;

[0009] A friction positioning assembly, wherein the friction positioning assembly is arranged on the lower end surface of the flange;

[0010] The one-way fixing component includes a cavity groove, which is opened on the bottom surface of the flange plate. A positioning strip is connected to a pin shaft in the cavity groove. A slot is opened on the positioning strip, and a pin shaft is inserted into the slot. The positioning strip is movably connected in the cavity groove through the pin shaft. A clearance groove is opened on the bottom surface of the positioning strip, and an anti-slip strip is embedded in the clearance groove.

[0011] As a further technical solution, the positioning strip is a triangular structure, and a portion of the positioning strip is embedded in the flange.

[0012] As a further technical solution, the friction positioning assembly includes a positioning groove, which is opened at the bottom edge of the flange, a positioning rod is arranged in the positioning groove, a movable tube is mounted on the positioning rod, a push spring is arranged in the positioning groove, a triangular anti-sliding block is arranged at the end of the push spring, and the triangular anti-sliding block extends out of the positioning groove.

[0013] As a further technical solution, the number of the positioning bars is the same as the number of the positioning grooves, that is, 12 both.

[0014] As a further technical solution, the positioning groove is a cylindrical cavity, and the outer diameter of the push spring matches the inner diameter of the positioning groove.

[0015] As a further technical solution, the hexagonal nut and the flange are integrally formed.

[0016] As a further technical solution, the flange is connected to the hexagonal nut, a through hole is formed on the flange, and the through hole matches the inner diameter of the hexagonal nut.

[0017] As a further technical solution, the hexagonal nut is a hexagonal structure, and the flange is a circular structure.

[0018] The working principle and beneficial effects of the utility model are:

[0019] The utility model uses the cavity groove positioning strip, the slotted hole, the give way groove and the anti-skid strip in the one-way fixing component to increase the friction force when the nut rotates in the reverse direction, so that the multiple anti-skid strips increase the friction resistance to prevent the nut from rotating in the reverse direction. The positioning groove, the positioning rod, the movable tube, the push spring and the triangular anti-sliding block in the friction positioning component cooperate to increase the friction force at the edge of the flange to prevent the nut from rotating in the reverse direction.

[0026] The following will be combined with 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.

[0027] like Figure 1~Figure 4 As shown, this embodiment provides a flange nut with good wear resistance, including

[0028] A hexagonal nut 1, the bottom of which is connected with a flange 2;

[0029] A one-way fixing component 3, which is arranged at the bottom of the flange 2;

[0030] A friction positioning assembly 4, which is arranged on the lower end surface of the flange 2;

[0031] The one-way fixing component 3 includes a cavity groove 3-1, which is opened on the bottom surface of the flange 2. A positioning strip 3-2 is connected to the pin shaft in the cavity groove 3-1. A slot 3-3 is opened on the positioning strip 3-2, and a pin shaft is inserted into the slot 3-3. The positioning strip 3-2 is movably connected to the cavity groove 3-1 through the pin shaft. A clearance groove 3-4 is opened on the bottom surface of the positioning strip 3-2, and an anti-slip strip 3-5 is embedded in the clearance groove 3-4.

[0032] In this embodiment, the positioning strip 3-2 is located in the cavity groove 3-1, and the anti-slip strip 3-5 partially extends out of the cavity groove 3-1. When the nut is normally tightened and screwed, the anti-slip strip 3-5 will not cause too much resistance. When the nut becomes loose, the anti-slip strip 3-5 produces an anti-slip effect, which increases the resistance of the nut and prevents the nut from rotating in the opposite direction.

[0033] Specifically, the positioning strip 3-2 is a triangular structure, a part of the positioning strip 3-2 is embedded in the flange 2, the friction positioning assembly 4 includes a positioning groove 4-1, the positioning groove 4-1 is opened at the bottom edge of the flange 2, a positioning rod 4-2 is arranged in the positioning groove 4-1, a movable tube 4-3 is mounted on the positioning rod 4-2, a pushing spring 4-4 ​​is arranged in the positioning groove 4-1, a triangular anti-sliding block 4-5 is arranged at the end of the pushing spring 4-4, and the triangular anti-sliding block 4-5 extends out of the positioning groove 4-1.

[0034] In this embodiment, the push spring 4-4 ​​pushes the triangular anti-sliding block 4-5 to extend. The triangular anti-sliding block 4-5 slides from the side with a smaller angle during the normal rotation of the nut, which will not cause too much resistance to the rotation of the nut. When the nut rotates in the opposite direction, the side with a larger angle of the triangular anti-sliding block 4-5 increases the friction force to prevent the nut from rotating in the opposite direction.

[0035] Furthermore, the number of positioning strips 3-2 and positioning grooves 4-1 is the same, that is, 12 each. The positioning groove 4-1 is a cylindrical cavity. The outer diameter of the push spring 4-4 ​​matches the inner diameter of the positioning groove 4-1. The hexagonal nut 1 and the flange 2 are integrally formed.

[0036] In this embodiment, the preferred number setting is that the number of positioning strips 3 - 2 and positioning grooves 4 - 1 is 12, which can be changed at will in actual situations.

[0037] Furthermore, the flange 2 is connected to the hexagonal nut 1, and a through hole 5 is formed on the flange 2. The through hole 5 matches the inner diameter of the hexagonal nut 1. The hexagonal nut 1 is a hexagonal structure, and the flange 2 is a circular structure.

[0038] In this embodiment, the through hole 5 can be passed through when the bolt is screwed.

[0039] When the nut needs to be screwed, the positioning strip 3-2 is located in the cavity groove 3-1, and the anti-slip strip 3-5 partially extends out of the cavity groove 3-1. When the nut is normally locked and screwed, the anti-slip strip 3-5 will not cause too much resistance. The push spring 4-4 ​​pushes the triangular anti-sliding block 4-5 to extend. The triangular anti-sliding block 4-5 slides from the side with a smaller angle during the normal rotation of the nut, and will not cause too much resistance to the rotation of the nut. When the nut rotates in the opposite direction, the anti-slip strip 3-5 has an anti-slip effect, which increases the resistance of the nut. The side with a larger angle of the triangular anti-sliding block 4-5 increases the friction to prevent the nut from rotating in the opposite direction.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
