Description

Technical Field

[0001] This utility model relates to the field of nut technology, specifically a novel nut that can be cut off. Background Technology

[0002] Nuts are common fasteners whose main function is to connect and fix two or more parts together by cooperating with bolts or screws. Nuts usually have an internally threaded hole that can form a matching thread structure with the externally threaded bolts or screws, thereby achieving a fastening effect. The performance grade of a nut is usually related to its tensile strength. For example, the ISO standard M4 to M10 specifications have performance grades ranging from 4 to 12. The higher the grade, the stronger its load-bearing capacity. In addition, the design of a nut also needs to consider factors such as its height, diameter range, and thread type. In practical applications, the choice of nut needs to be matched according to specific requirements. For example, in the case of anti-loosening, a double nut structure with a washer can be selected, while in the environment requiring waterproof and dustproof protection, a cap nut can be selected.

[0003] In existing technologies, in engineering construction, equipment maintenance, rail transit, power facilities and other occasions, once conventional nuts are installed and locked, if the threads become locked, rusted, deformed or need to be disassembled urgently, high-strength wrenches, impact tools or cutting machines are often required to assist in removal. This is difficult to operate and poses safety hazards. Especially in situations that require emergency unloading or one-time installation, traditional structures cannot meet the needs of rapid disconnection or forced separation. Therefore, there is an urgent need to provide a new type of nut with a reasonable structural design, safety and controllability, and a cut-off function. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a novel cuttable nut to solve the technical problem that in engineering construction, equipment maintenance, rail transit, power facilities and other occasions, once conventional nuts are installed and locked, if the threads are locked, rusted, deformed or need to be disassembled in an emergency, high-strength wrenches, impact tools or cutting machines are often required for disassembly, which is difficult to operate and poses safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel cuttable nut, comprising a nut, the nut being in the shape of a standard external hexagonal nut, for use with conventional wrenches, and made of high-strength steel or alloy material, the nut having a thread on its inner side, an upper groove symmetrically formed at the top of the nut's sidewall, and a lower groove symmetrically formed at the bottom of the nut's sidewall.

[0006] By adopting the above technical solution, an upper and lower groove is set on the nut body, and a reinforcing rod is embedded in the groove. The screw and threaded hole are used for fixing to form a stable structure. Under normal use, this structure has the same function as an ordinary nut, which can achieve high-strength fastening and meet various installation requirements. When it is necessary to remove it, after removing the screw, the groove becomes a stress concentration area. The operator can quickly break the nut along the groove by mechanical external force without special cutting tools, so as to achieve the purpose of quick release. This structure effectively avoids the problem of traditional nuts being difficult to remove in situations such as rust, seizing, or space constraints. Disassembly can be completed without damaging the screw or using high-strength tools, saving time, improving efficiency, and having good practicality.

[0007] Furthermore, multiple sets of reinforcing rods are fixedly connected to the inner sides of both the upper and lower grooves, and the reinforcing rods are made of high-strength steel.

[0008] By adopting the above technical solution, the reinforcing rod strengthens the nut structure and prevents premature breakage. Under normal use, the structure functions the same as a regular nut, achieving high-strength fastening and meeting various installation requirements.

[0009] Furthermore, the nut has symmetrically threaded holes on its sidewalls, and screws are threaded into these holes.

[0010] By adopting the above technical solution, the screw connected by the internal thread of the threaded hole plays a role in strengthening the structural strength of the nut and preventing premature breakage. Under normal use, this structure has the same function as an ordinary nut, which can achieve high-strength fastening and meet various installation requirements.

[0011] Furthermore, the upper and lower grooves form a pre-defined stress concentration area, which will preferentially fracture when an external impact or prying force is applied.

[0012] By adopting the above technical solution, when disassembly is required, the groove becomes a stress concentration area after the screw is removed. The operator can quickly break the nut along the groove by mechanical external force without special cutting tools, thus achieving the purpose of quick release.

[0013] Furthermore, the screw can be unscrewed before it breaks, thereby releasing the stress support in the groove and facilitating the breakage of the nut along the groove direction.

[0014] By adopting the above technical solution, a stable structure is formed by fixing with screws and threaded holes. In normal use, this structure functions the same as an ordinary nut, achieving high-strength fastening and meeting various installation requirements.

[0015] Furthermore, the upper and lower grooves are weakened or laser-precision shaped so that they can be quickly broken by external force during disassembly, and the nut can be automatically released after breakage, achieving non-destructive disassembly. The nut is quickly broken along the groove by mechanical external force, achieving the purpose of quick release.

[0016] By adopting the above technical solution, an upper groove and a lower groove are set, and a reinforcing rod is embedded inside the groove.

[0017] In summary, this utility model has the following beneficial effects: By setting an upper groove and a lower groove on the nut body and embedding a reinforcing rod inside the groove, and using a screw and threaded hole for fixation, a stable structure is formed. Under normal use, this structure functions the same as an ordinary nut, achieving high-strength fastening and meeting various installation requirements. When disassembly is required, after removing the screw, the groove becomes a stress concentration area, allowing the operator to quickly break the nut along the groove using mechanical external force without special cutting tools, achieving quick release. This structure effectively avoids the problem of traditional nuts being difficult to remove in situations such as corrosion, seizing, or limited space. Disassembly can be completed without damaging the screw or using high-strength tools, saving time, improving efficiency, and having good practicality. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] A new type of nut that can be cut off, such as Figure 1-4As shown, it includes nut 1, which is a standard external hexagonal nut shape, used for installation with a conventional wrench, and can be made of high-strength steel or alloy material. Nut 1 has threads on its inner side, and upper grooves 2 are symmetrically formed on the top of the side wall of nut 1, and lower grooves 3 are symmetrically formed on the bottom of the side wall of nut 1. Specifically, nut 1 is installed on bolts with standard tools such as wrenches to complete conventional tightening operations.

[0026] Please see Figure 1 and Figure 2 Multiple sets of reinforcing rods 4 are fixedly connected to the inner sides of the upper groove 2 and the lower groove 3. The reinforcing rods 4 are made of high-strength steel. The nut 1 has symmetrically threaded holes 5 on its side wall. The threaded holes 5 are threaded with screws 6. The upper groove 2 and the lower groove 3 form a preset stress concentration area. When an external impact or prying force is applied, this area will break first. The screws 6 can be unscrewed before breaking, thereby releasing the force support in the groove, which makes it easier for the nut 1 to break along the groove direction. The upper groove 2 and the lower groove 3 are weakened or laser precision machined so that they can be quickly broken by external force during disassembly, and the nut will be automatically released after breaking, achieving non-destructive disassembly.

[0027] Specifically, when it is necessary to disassemble or quickly release nut 1, first unscrew the screws 6 on both sides from the corresponding threaded holes 5 to release the fixed connection to the nut body. Nut 1 forms a weak area in terms of structure. Then, an impact tool or special tool can be used to apply force to the upper groove 2 and the lower groove 3. Because it is a stress concentration design part, the material will be brittlely fractured first under the action of external force, so that nut 1 breaks into two pieces along the groove position.

[0028] After the breakage is completed, nut 1 can be removed directly without the need for screwing, achieving quick and non-destructive disassembly without cutting. This structure is particularly suitable for occasions with limited space, frequent disassembly and assembly, emergency maintenance, or anti-theft packaging, effectively improving disassembly and assembly efficiency and safety.

[0029] The working principle of this utility model is as follows: When in use, the nut 1 is installed on the bolt with a standard tool such as a wrench to complete the conventional tightening operation. The nut 1 body is provided with symmetrically distributed upper grooves 2 and lower grooves 3, and a reinforcing rod 4 is inserted inside. The screw 6 connected by the internal thread through the threaded hole 5 plays the role of strengthening the structural strength of the nut and preventing premature breakage.

[0030] When it is necessary to disassemble or quickly release nut 1, first unscrew the screws 6 on both sides from the corresponding threaded holes 5 to release the fixed connection to the nut body. Nut 1 forms a weak area in terms of structure. Then, an impact tool or special tool can be used to apply force to the upper groove 2 and the lower groove 3. Because it is a stress concentration design part, the material will be brittlely fractured first under the action of external force, so that nut 1 breaks into two pieces along the groove position.

[0031] After the breakage is completed, nut 1 can be removed directly without the need for screwing, achieving quick and non-destructive disassembly without cutting. This structure is particularly suitable for occasions with limited space, frequent disassembly and assembly, emergency maintenance, or anti-theft packaging, effectively improving disassembly and assembly efficiency and safety.

[0032] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
