Description

Technical Field

[0001] This utility model relates to the field of nuts, and more specifically, to a special type of nut. Background Technology

[0002] Nuts are fasteners that are screwed together with bolts or screws to provide a fastening effect. They are an essential component in all manufacturing machinery and are classified into several types based on their material, such as carbon steel, stainless steel, and non-ferrous metals (e.g., copper).

[0003] Chinese Patent No. CN2784651Y discloses an anti-theft nut, which includes a nut body. The nut body has a convex structure with an annular groove on its upper outer circumference. The upper circumference of the annular groove has 2-8 vertical grooves perpendicular to the annular groove. A combination shield is installed on the outside of the nut body. A locking pin hole is provided on the upper part of the combination shield at the position corresponding to the annular groove of the nut body. A locking pin is installed in the hole.

[0004] The anti-theft structure on the combination lock cover in the above scheme makes the production and assembly cost of a single nut relatively high, and the operation of disassembling and reassembling the combination lock cover and tightening the screws is relatively troublesome.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a special nut.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a special nut, including a fastener that matches a bolt and a force-bearing component that matches a wrench, wherein the force-bearing component is sleeved outside the fastener and rotates relative to the fastener, the fastener and the force-bearing component are relatively fixed by a connecting component, and the connecting component, the fastener, and the force-bearing component are detachable.

[0008] The present invention is further configured such that: the fastener is cylindrical and has a threaded hole in the center; the force-bearing component is hexagonal prism and has a cavity in the center to accommodate the rotation of the fastener.

[0009] The present invention is further provided with limiting structures at the upper and lower ends of the cavity for limiting the fasteners and preventing them from leaving the cavity.

[0010] The present invention is further configured such that: the limiting structure includes an annular groove formed on the inner wall of the upper end of the cavity and a retaining spring embedded in the annular groove, the retaining spring abutting against the top surface of the fastener.

[0011] The present invention is further configured such that the retaining ring is C-shaped and has caliper holes at both ends.

[0012] The present invention is further configured such that: the limiting structure also includes a retaining ring integrally formed on the inner wall of the lower end of the cavity, and the retaining ring abuts against the bottom end face of the fastener.

[0013] The present invention is further configured such that: the connecting member is a locking pin, the force-bearing member has a through hole for passing through the locking pin, and the fastener has a locking hole for accommodating the embedded end of the locking pin.

[0014] The present invention is further configured such that: the locking pin is cylindrical, and both the through hole and the locking hole are circular.

[0015] In summary, this utility model has the following beneficial effects: by separating the connector, fastener, and force-bearing component, the fastener and force-bearing component can rotate relative to each other. When the wrench applies force to the force-bearing component, the force-bearing component rotates freely and cannot rotate the fastener, thus preventing the nut from being easily rotated by the wrench. After connecting the fastener and force-bearing component by installing the connector, the fastener and force-bearing component can be rotated synchronously by rotating the wrench, thereby rotating the nut normally. Its structure is simple and its operation is relatively simple and convenient. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0021] A special type of nut, such as Figure 1 and Figure 2As shown, the device includes a fastener 1 that mates with a bolt and a force-bearing component 2 that mates with a wrench. The force-bearing component 2 is sleeved outside the fastener 1 and rotates relative to the fastener 1. The fastener 1 and the force-bearing component 2 are relatively fixed by a connector 3. The connector 3, fastener 1, and force-bearing component 2 are detachable. By separating the connector 3 from the fastener 1 and the force-bearing component 2, the fastener 1 and the force-bearing component 2 can rotate relative to each other. When the wrench applies force to the force-bearing component 2, the force-bearing component 2 rotates independently and cannot rotate the fastener 1. This prevents the nut from being easily turned by the wrench. After the fastener 1 and the force-bearing component 2 are connected by the connector 3, the fastener 1 and the force-bearing component 2 can be rotated synchronously by rotating the wrench, thus turning the nut normally. Its structure is simple and its operation is relatively simple and convenient.

[0022] Fastener 1, load-bearing component 2, and connector 3 are all made of brass, making the special nut a brass material with good corrosion resistance. It can resist the erosion of air, water, and some weak acids and alkalis. This characteristic allows the nut to maintain its performance and extend its service life even in humid and highly corrosive environments.

[0023] Specifically, such as Figure 1 and Figure 2 As shown, the fastener 1 is cylindrical with a threaded hole 4 in the center for engaging with a stud. The force-bearing component 2 is hexagonal and engages with a wrench. The force-bearing component 2 has a cavity 5 in the center to accommodate the rotation of the fastener 1. By providing the cavity 5, even if the force-bearing component 2 is rotated, the fastener 1 will remain stationary within the cavity 5 when the connecting component 3 is separated from the fastener 1 and the force-bearing component 2. This allows the fastener 1 and the force-bearing component 2 to rotate relative to each other, preventing the entire special nut from loosening. After connecting the fastener 1 and the force-bearing component 2 with the connecting component 3, the fastener 1 will not spin freely within the cavity 5, allowing the entire special nut to be rotated and thus enabling disassembly and assembly.

[0024] like Figure 2 and Figure 3 As shown, the connector 3 is a locking pin. The force-bearing component 2 has two symmetrically arranged through holes 10 for the locking pin to pass through. The fastener 1 has two symmetrically arranged locking holes 11 for accommodating the end of the locking pin. After the connector 3 passes through the through holes 10 and is embedded in the locking holes 11, the force-bearing component 2 can transmit the force to the fastener 1 through the locking pin after being subjected to force, thereby causing the fastener 1 to rotate with the force-bearing component 2. This allows the wrench to successfully rotate the special nut. Furthermore, the locking pin is cylindrical, and both the through holes 10 and the locking holes 11 are circular. This design allows the locking pin to easily pass through the through holes 10 and be locked into the locking holes 11 without special angle adjustment, making operation convenient.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, the upper and lower ends of the cavity 5 are provided with limiting structures to prevent the fastener 1 from detaching from the cavity 5. The limiting structures can prevent the fastener 1 from detaching from the cavity 5, thereby keeping the fastener 1 and the force-bearing component 2 as a single unit, which is convenient for use. Specifically, the limiting structure includes an annular groove 6 formed on the inner wall of the upper end of the cavity 5 and a retaining spring 7 embedded in the annular groove 6. The retaining spring 7 abuts against the top surface of the fastener 1. The retaining spring 7 is C-shaped, and both ends of the retaining spring 7 are provided with clamp holes 8. The limiting structure also includes a retaining ring 9 integrally formed on the inner wall of the lower end of the cavity 5. The retaining ring 9 abuts against the bottom surface of the fastener 1. During the cutting and forming process of cavity 5, ring 9 can be formed by retaining a portion. After fastener 1 is placed in cavity 5, it can naturally restrict fastener 1 and prevent fastener 1 from falling off the bottom of cavity 5. This ensures that cavity 5 has only one opening for accommodating fastener 1 for insertion and removal. By embedding snap ring 7 into ring groove 6, snap ring 7 can restrict fastener 1 from falling off from the other opening of cavity 5, thus providing a good fixing effect for fastener 1. The clamp holes 8 provided at both ends of snap ring 7 facilitate the control of snap ring 7 with clamps, making it convenient for snap ring 7 to be installed and removed.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
