Description

Technical Field

[0001] This utility model relates to the field of ball head bolt technology, specifically to lightweight, high-strength, wear-resistant ball head bolts. Background Technology

[0002] Ball head bolts are a special type of mechanical fastener. Their core feature is that one or both ends are designed with a spherical structure (ball head). By cooperating with matching ball seats or sockets, they can achieve multi-degree-of-freedom movement or angle adjustment. This design makes them irreplaceable in mechanical transmission, suspension systems, joint connections and other fields.

[0003] Traditional ball head bolts are usually a single piece. When ball head bolts are used frequently, the thread grooves on the bolt will wear and become damaged, requiring the replacement of the entire bolt, which results in relatively high usage costs. Utility Model Content

[0004] The purpose of this invention is to produce lightweight, high-strength, wear-resistant ball head bolts, solving the problem that traditional ball head bolts are usually one piece, and when ball head bolts are used frequently, the thread grooves on the bolt will wear and be damaged, requiring the replacement of a whole bolt, which leads to relatively high usage costs.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a lightweight, high-strength, wear-resistant ball head bolt, including a mounting rod and a ball head. One end of the mounting rod has a first threaded groove, and the outer surface of the mounting rod has several limiting grooves. The other end of the mounting rod has a second threaded groove, and the inside of the ball head has a third threaded groove. The third threaded groove and the inside of the first threaded groove are threadedly connected to a first locking bolt, and a threaded tube mechanism is sleeved on the outer surface of the mounting rod.

[0007] Connect the ball head to the mounting rod, at which point the first and third threaded grooves coincide. Then, thread the first locking bolt into the first and third threaded grooves to complete the installation between the mounting rod and the ball head. When disassembly is required, reverse the above steps to disassemble the mounting rod and the ball head, allowing for the replacement of ball heads of different sizes and improving the flexibility of use.

[0008] Furthermore, the threaded tube mechanism includes a threaded sleeve that is fitted onto the outer surface of the mounting rod;

[0009] Furthermore, several limiting blocks are fixedly installed inside the threaded sleeve;

[0010] Furthermore, a through groove is provided at one end of the threaded sleeve;

[0011] Furthermore, a second locking bolt is inserted into the inside of the through groove, and the second locking bolt is connected by the internal threads of the through groove and the second threaded groove;

[0012] Furthermore, each of the limiting blocks is inserted into a limiting groove;

[0013] The initial installation of the threaded sleeve is completed by inserting several limiting blocks inside the limiting groove on the mounting rod. At this time, the position of the through groove coincides with the position of the second thread groove. The second locking bolt is then threaded through the through groove and connected into the second thread groove to complete the fixed installation of the threaded sleeve. When disassembly is required, the above operation of the threaded tube mechanism is reversed to complete the disassembly of the threaded tube mechanism. This avoids the situation where the thread groove on the ball head bolt is damaged and the entire bolt needs to be replaced, thus reducing costs.

[0014] This utility model has the following beneficial effects:

[0015] (1) In this utility model, the ball head is connected to the mounting rod. At this time, the first thread groove and the third thread groove overlap. Then, the first locking bolt is threaded into the first thread groove and the third thread groove to complete the installation between the mounting rod and the ball head. When disassembly is required, the above operation is reversed to complete the disassembly between the mounting rod and the ball head, so that different sizes of ball heads can be replaced, which improves the flexibility of use.

[0016] (2) In this utility model, several limiting blocks inside the threaded sleeve are inserted into the limiting groove on the mounting rod to complete the initial installation of the threaded sleeve. At this time, the position of the through groove coincides with the position of the second thread groove. The second locking bolt is threaded through the through groove and connected into the inside of the second thread groove to complete the fixed installation of the threaded sleeve. When disassembly is required, the above-mentioned threaded tube mechanism is operated in reverse to complete the disassembly of the threaded tube mechanism, avoiding the situation where the thread groove on the ball head bolt is damaged and the whole bolt needs to be replaced, thus achieving the effect of reducing costs.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
