Description

Technical Field

[0001] The utility model belongs to the technical field of nuts, and in particular relates to an anti-wear hexagonal nut. Background Art

[0002] Hexagonal nuts, also known as hexagonal nuts, are a type of fastener. They are named after the six hexagonal faces. They are used with screws, bolts, and screws to connect and fasten machine parts.

[0003] The patent with publication number CN115434999A in the traditional technology discloses a multi-directional hexagonal nut. It discloses a multi-directional hexagonal nut that can provide three degrees of freedom of screwing direction by cooperating with an inner slide groove and a middle slide groove, which is convenient for the wrench to move and screw in a narrow space. At the same time, it can lock the screw by cooperating with a rubber sleeve and a sliding ring to enhance the stability of the screw. The multi-directional hexagonal nut is characterized in that a sliding cavity is opened on the end surface of one end of the inner screw sleeve, the sliding cavity is an annular cavity, the limit ring is placed inside the sliding cavity, the sliding ring cover is placed on the mouth of the sliding cavity, and is connected to the limit ring inside the sliding cavity, the ring width of the sliding ring is smaller than the ring width of the limit ring, the limit ring is made of rubber material, the rubber sleeve is placed on the inner wall of the inner screw sleeve, and is located at one end of the inner screw sleeve, the rubber sleeve is connected with the inside of the sliding cavity through an air hole, and a thread is opened on the inner wall of the inner screw sleeve.

[0004] However, there are some problems with traditional technology: when nuts and bolts are used together to fasten workpieces, the nuts usually need to be screwed to the limit to ensure the firmness of the connection. However, this operation method often results in a large force being required to remove the nuts later.

[0005] People often use a spanner to assist in removing nuts. However, when using a spanner for removal, since the clamping clearance of the spanner is usually larger than the outer diameter of the nut, the corners of the hexagonal nut may be worn when a large force is applied to rotate and remove the nut. Once the corners of the nut are worn, the nut cannot be clamped stably, and the removal work cannot be completed smoothly. Utility Model Content

[0006] The utility model aims to provide a wear-resistant hexagonal nut to solve the technical problems raised in the background technology.

[0027] The disclosure below provides many different embodiments or examples for realizing different structures of the embodiments of the present utility model. In order to simplify the disclosure of the embodiments of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0028] In order to better understand the purpose, structure and function of the utility model, the wear-resistant hexagonal nut of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1-6 As shown, the utility model is an anti-wear hexagonal nut, including a nut body 1, six straight surfaces 2 are arranged on the outside of the nut body 1 in a hexagonal arrangement, the nut body 1 is provided with six fillets 3, a fillet 3 is arranged at the connection between two adjacent straight surfaces 2 of the nut body 1, a slot 5 is respectively arranged in the middle of the straight surface 2 of each nut body 1, and a screw hole 6 is arranged inside the nut body 1.

[0030] The wear-resistant hexagonal nut is designed to effectively solve the problem that when people use a wrench to assist in removing the nut, the clamping clearance of the wrench is usually larger than the outer diameter of the nut, which may cause the corners of the hexagonal nut to wear when applying a large force to rotate and remove the nut:

[0031] The exterior of the nut body 1 is designed to be a standard hexagonal shape with six straight faces 2. This standardized design ensures that the nut is compatible with most common tools, such as wrenches and sockets; six fillets 3 are provided at the connection of each straight face 2. The fillet 3 design helps to disperse the pressure applied by the wrench and reduce the presence of sharp edges, thereby reducing the risk of wear on the corners. Even under intensive use, the fillet 3 can effectively protect the edge of the nut from damage. At the same time, it can reduce the risk of slipping when the adjustable spanner contacts the nut. The fillet 3 can guide the spanner to better fit the plane of the nut, ensuring uniform and stable force. Only when the adjustable spanner is close to the plane of the nut body 1 can it be effectively twisted, thus avoiding the problems caused by edge wear of traditional hexagonal nuts.

[0032] A slot 5 is provided in the middle of each straight surface 2, and corresponding tools, such as a special wrench, can be inserted into these slots 5 to twist the nut when it is damaged. This design provides a variety of installation and disassembly methods, so that even in extreme cases, users can still use spare tools to complete the disassembly operation, which increases the practicality and flexibility of the nut. A screw hole 6 is provided inside the nut body 1 for mating with a screw 13 or a screw. The standardized screw hole 6 design ensures that the nut can fit tightly with screws 13 of different specifications to adapt to various application scenarios.

[0033] In this embodiment, there are six slots 5, which are arranged in a circumferential array outside the nut. A washer 4 is fixedly connected to the lower part of the nut body 1, and the lower part of the slot 5 passes through the edge of the washer 4. A placement groove 8 is formed at the lower part of the washer 4, and a rubber sheet 7 is pasted inside the placement groove 8.

[0034] A rubber sheet 7 is added to the bottom of the nut body 1. This rubber sheet 7 can significantly increase the friction between the washer 4 and the surface of the fixing member, thereby improving the firmness and durability of the connection.

[0035] In this embodiment, a driving cap 16 is further provided on the outside of the nut body 1, and a groove 9 matching the shape of the nut body 1 is provided at the bottom of the driving cap 16, and the driving cap 16 is plugged into the slot 5. A connecting rod 10 is fixedly connected to the top of the driving cap 16, and a fixing seat 11 is fixedly connected to the top of the connecting rod 10, and a sliding rod 12 is slidably installed inside the fixing seat 11. Limiting plates 15 are fixedly connected to both sides of the sliding rod 12, and a screw 13 is screwed to the top of the fixing seat 11, and the bottom of the screw 13 is pressed and contacted with the sliding rod 12, and a rotating disk 14 is fixedly connected to the top of the screw 13 through the fixing seat 11.

[0036] Specifically, first, align the groove 9 of the drive cap 16 with the nut body 1, and plug it into the nut to ensure that the two are tightly combined. By sliding the slide rod 12, adjust its position in the fixed seat 11 to form a lever of appropriate length. The limit plates 15 at both ends of the slide rod 12 ensure that the movement range of the slide rod 12 in the fixed seat 11 is controlled to prevent the slide rod 12 from sliding out or shifting, thereby ensuring smooth and precise operation. The position of the slide rod 12 can be adjusted according to specific operating requirements to achieve the best labor-saving effect. The design of the turntable 14 allows the user to easily adjust the degree of compression of the screw 13. The slide rod 12 can be fixed or released through simple manual operation, which improves the convenience and efficiency of operation. After the drive cap 16 and the nut body 1 are tightly combined, the user can rotate the slide rod 12, and through the transmission action of the connecting rod 10 and the drive cap 16, the nut can be smoothly driven to perform steering operations.

[0037] The working principle of the wear-resistant hexagonal nut is as follows: a slot 5 is provided in the middle of each straight surface 2, and corresponding tools, such as a special wrench, can be inserted into the slot 5 to twist the nut when it is damaged. This design provides a variety of installation and disassembly methods, so that even in extreme cases, users can still use spare tools to complete the disassembly operation, which increases the practicality and flexibility of the nut. A screw hole 6 is provided inside the nut body 1 for mating with a screw 13 or a screw. The standardized screw hole 6 design ensures that the nut can be tightly matched with screws 13 of different specifications to adapt to various application scenarios.
