Abstract
Description
Technical Field
[0001] This utility model relates to the field of stud technology, specifically a stud with an extended structure. Background Technology
[0002] Studs, also known as double-ended studs, are cylindrical fasteners with threads at both ends. They are widely used in power, chemical, oil refining, valve, railway, bridge, steel structure, auto parts, machinery, boiler steel structures, cranes, large-span steel structures, and large buildings.
[0003] Therefore, when operators find that the length of the existing studs is insufficient or outside the standard specifications, custom studs are required, which increases the cost of using them. A common solution is to connect two studs of the same model with a nut, but this does not result in a continuous thread, and the connected studs have low strength. Furthermore, the exposed joint is prone to rust, which affects the use of the studs. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a stud with an extended structure, solving the problem mentioned in the background section regarding studs with extended structures. Existing studs often suffer from insufficient length or require lengths outside the standard specifications, necessitating customization and increasing usage costs. A common solution is to connect two studs of the same model with a nut; however, this results in a lack of continuous thread, low strength at the connection point, and susceptibility to rust, affecting the stud's usability.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a stud with an extended structure, including a first stud, a connecting mechanism threadedly installed at one end of the first stud, a protective mechanism threadedly installed on the outer wall of the connecting mechanism, a second stud threadedly installed on the inner wall of the connecting mechanism, and a reinforcing post integrally provided at one end of the second stud.
[0008] Furthermore, both the first stud and the second stud have screws on their outer walls.
[0009] Furthermore, the connecting mechanism includes a connecting sleeve, the inner wall of which has an inner cylinder, the outer wall of which has an external thread, and a bending plate integrally welded around the outer wall of the connecting sleeve. A clamping block is integrally provided on one side of the bending plate, and the inner wall of the clamping block has an internal thread.
[0010] Furthermore, the left end of the connecting sleeve is threaded to the first stud, and the inner cylinder of the connecting sleeve is inserted into the reinforcing post.
[0011] Furthermore, the clamping block is integrally formed with the connecting sleeve via a bent plate, and the clamping block is threadedly connected to the second stud via an internal thread on its inner wall.
[0012] Furthermore, the protective mechanism includes an assembly cylinder, the outer wall of which is wrapped with a rubber ring, and the inner wall of which is fitted with a waterproof ring.
[0013] Furthermore, the inner wall of the assembly cylinder is threadedly connected to the outer thread of the connecting sleeve via a thread.
[0014] (III) Beneficial Effects
[0015] This utility model provides a stud with an extended structure, which has the following beneficial effects:
[0016] The connecting sleeve is threaded to the first stud, and the second stud is threaded to the inner thread of the outer wall of the clamping block. The reinforcing post at one end of the second stud is inserted into the inner cylinder, thereby improving the overall connection strength and effectively ensuring the effectiveness of the screw. This makes the screw connection more secure and less prone to loosening.
[0017] The assembly sleeve and the connecting sleeve are connected by external threads. The assembly sleeve compresses the bending plate and the clamping block, thereby improving the connection strength of the second screw. The rubber ring on the outer wall of the assembly sleeve and the waterproof ring on the inner wall of the assembly sleeve improve the overall sealing performance, prevent the connection from being exposed and causing rust and corrosion, and increase the service life of the stud.
