Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical basic parts technology, and more specifically, it relates to a hexagonal nut with elastic anti-loosening teeth. Background Technology
[0002] Hex nuts are one of the most basic fasteners in mechanical connections. With a hexagonal outer contour and internal thread structure as the core, they are used with bolts and studs to fasten parts. Their hexagonal design makes them easy to hold with a wrench, and the internal thread generates preload through screwing, converting axial force into clamping force on the connected parts. They are widely used in industrial manufacturing, construction, automotive and other fields.
[0003] The existing application number is CN202322048525.X. This utility model provides a hexagonal nut, a regular hexagon, with a threaded hole running through the middle of the regular hexagon, and limit holes on the inner sides of the corners of the regular hexagon. When loosening a rusted hexagonal nut, after the corners of the hexagonal nut are worn down by using a wrench, a special wrench is used to insert six metal rods arranged in a regular hexagonal shape and connected as one piece into the limit holes. By rotating the special wrench, the metal rods and the limit holes together drive the regular hexagon to rotate, causing the threaded hole to rotate around the tightened screw, which can loosen a rusted hexagonal nut with worn corners.
[0004] Based on the above, traditional hexagonal nuts rely on tools such as wrenches to tighten. Although this can ensure a high preload, in temporary fixing scenarios, the process of obtaining, positioning, and operating tools will significantly increase the complexity of the procedure. Especially in situations where space is limited or tools are inconvenient to carry, if you try to tighten them by hand, because the outer contour of the hexagonal nut is a regular hexagonal prism, the contact area between the hand and the nut surface is limited, and the friction of the metal surface is small. It is difficult to achieve the basic preload required for temporary fixing by hand, which easily leads to low efficiency. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a hexagonal nut with elastic anti-loosening teeth. This solves the problem that existing hexagonal nuts rely on tools such as wrenches for tightening. Although this can ensure a high preload, in temporary fixing scenarios, the process of obtaining, positioning, and operating tools significantly increases the complexity of the procedure. Especially in situations where space is limited or tools are inconvenient to carry, if one attempts to tighten by hand, the contact area between the hand and the nut surface is limited due to the regular hexagonal prism shape of the nut, and the low friction of the metal surface makes it difficult to achieve the basic preload required for temporary fixing by hand, easily leading to low efficiency.
[0006] The purpose and effect of this utility model of a hexagonal nut with elastic anti-loosening teeth are achieved by the following specific technical means: A hexagonal nut with elastic anti-loosening teeth includes a hexagonal nut body, a waterproof washer, a guide washer, a temporary operating handle, an anti-loosening reinforcement mechanism, and an operation enhancement mechanism. The waterproof washer is embedded in the upper end of the hexagonal nut body. The guide washer has a circular ring structure and is fixedly connected to the lower end of the hexagonal nut body. Two sets of temporary operating handles are provided, and the two sets of temporary operating handles are slidably connected to the left and right sides of the hexagonal nut body, respectively. The anti-loosening reinforcement mechanism is located on the outer side of the hexagonal nut body. The operation enhancement mechanism is located on the inner side of the temporary operating handle.
[0007] Furthermore, the anti-loosening reinforcement mechanism includes a connecting guide groove; the connecting guide groove is a frustoconical groove structure, and the connecting guide groove is opened at the lower inner side of the guide pad.
[0008] Furthermore, the anti-loosening reinforcement mechanism also includes: anti-loosening elastic teeth and connecting sealing gaskets; multiple sets of anti-loosening elastic teeth are provided, and the multiple sets of anti-loosening elastic teeth are respectively fixedly connected to the lower outer periphery of the guide gasket, and the multiple sets of anti-loosening elastic teeth are all spring steel structures with anti-slip texture on the lower side; the connecting sealing gasket is a circular rubber gasket structure, and the connecting sealing gasket is embedded in the lower end of the hexagonal nut body.
[0009] Furthermore, the anti-loosening reinforcement mechanism also includes: a reinforcing guard plate; the reinforcing guard plate is provided in six sets, all of which are L-shaped wear-resistant steel plate structures, and the six sets of reinforcing guard plates are respectively fixedly connected to the outer corner of the hexagonal nut body.
[0010] Furthermore, the operation enhancement mechanism includes: an ejection connecting spring, a storage slot, a storage plug, and a storage support spring; two sets of ejection connecting springs are provided, each fixedly connected to the inner side of the temporary operating handle, and the inner side of each set of ejection connecting springs is fixedly connected to the hexagonal nut body; two sets of storage slots are provided, each located behind the temporary operating handle; two sets of storage plugs are provided, each slidably connected to the inner side of the hexagonal nut body, and the rear end of each set of storage plugs is provided with a beveled structure; two sets of storage support springs are provided, each fixedly connected to the front end of the storage plug, and the front end of each set of storage support springs is fixedly connected to the hexagonal nut body.
[0011] Furthermore, the operation enhancement mechanism also includes: enhancement ejection grooves and ejection pressing components; two sets of enhancement ejection grooves are provided, both sets of enhancement ejection grooves are inclined groove structures, and the two sets of enhancement ejection grooves are respectively opened on the outside of the receiving plug; two sets of ejection pressing components are provided, the two sets of ejection pressing components are respectively slidably connected to the left and right sides inside the hexagonal nut body, and the two sets of ejection pressing components and the enhancement ejection grooves together form a wedge block structure.
[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention, through the design of an anti-loosening reinforcement mechanism, guides the hexagonal nut body when connecting it to the stud. This makes it easier for the nut body to connect to the stud. During connection, the anti-loosening elastic teeth are compressed and deformed, generating additional friction on the contact surface. This friction effectively prevents the hexagonal nut body from loosening under external forces such as vibration or impact. Simultaneously, the reinforcing plate strengthens the hexagonal nut body, reducing wear from the wrench and extending its service life. The connecting sealing gasket and waterproof gasket together provide dustproof and waterproof protection for the inner threads of the hexagonal nut body. Overall, this design improves the ease of connection, anti-loosening reliability, durability, and protective effect.
[0013] This invention, through the design of an efficiency-enhancing mechanism, allows workers to temporarily tighten the hexagonal nut body by turning a temporary operating handle when temporary tightening is required. In confined spaces, the temporary operating handle is first turned to pre-tighten the nut body. Then, the handle is pressed inwards, causing it to move and align with the storage slot and storage block. Under the action of the storage support spring, the storage block is inserted into the storage slot, locking the temporary operating handle. Workers can then fully tighten the nut body using a wrench. This allows for convenient temporary locking and pre-tightening of the nut body, especially in confined spaces. The locking of the temporary operating handle, achieved with the help of the storage support spring, does not affect subsequent full tightening with a wrench, thus improving the convenience and flexibility of temporary operations and adapting to different operational needs.

[0024] The anti-loosening reinforcement mechanism also includes: a reinforcing guard plate 104; there are six sets of reinforcing guard plates 104, all of which are L-shaped wear-resistant steel plate structures, and the six sets of reinforcing guard plates 104 are respectively fixedly connected to the outer corner of the hexagonal nut body 1.
[0025] The specific usage and function of this embodiment are as follows: When it is necessary to connect the hexagonal nut body 1 to the stud, the connecting guide groove 101 guides the hexagonal nut body 1, making it easier for the hexagonal nut body 1 to connect to the stud. During connection, the anti-loosening elastic teeth 102 are squeezed and deformed, thereby generating additional friction on the contact surface.

At the same time, the reinforcing guard plate 104 strengthens the hexagonal nut body 1, reduces the wear of the hexagonal nut body 1 by the wrench, and extends the service life of the hexagonal nut body 1.

When turning the hexagonal nut body 1 in a relatively narrow space, first turn the temporary operating handle 4 to pre-tighten the hexagonal nut body 1, and then press the temporary operating handle 4 inward. The temporary operating handle 4 moves inward, causing the storage slot 402 to align with the storage plug 403. The storage plug 403 then stores the support spring. Under the action of the spring 404, the storage block 403 is inserted into the storage slot 402, which locks the temporary operating handle 4. At this time, the worker can use a wrench to fully tighten the hexagonal nut body 1. When the temporary operating handle 4 is needed, the pressing member 406 is pushed out inward.

Under the action of the ejection connecting spring 401, the temporary operating handle 4 is ejected.
