Description

Technical Field

[0001] This utility model relates to the field of hardware tools, and in particular to a short-head sleeve bolt that is easy to install. Background Technology

[0002] With the rapid development of electric and hybrid vehicles, battery packs, as core components of new energy vehicles, have attracted much attention for their safety, reliability, and durability. Battery packs are typically composed of multiple battery cells, which are fixed together by a series of mechanical connection structures to ensure their stability and safety during vehicle operation. Among these, short-head sleeve bolts, as a key fastener, play an important role in the connection of battery packs.

[0003] However, existing short-head sleeve bolts still have some shortcomings and areas for improvement in practical use. Due to the complex structure of the battery pack and the small gaps between the components, existing bolts are not convenient to use. At the same time, since wiring is required during battery installation and connection, the existing structure cannot perform the wiring process. Furthermore, existing bolts are prone to stripping after long-term use, making them difficult to tighten. Therefore, those skilled in the art have provided a short-head sleeve bolt that is easy to install, in order to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a convenient short-head sleeve bolt. By setting a short-head bolt, the problems of interference and simple installation are effectively solved. At the same time, anti-slip blocks are set on the six side walls of the short-head bolt to provide a certain friction force and prevent stripping during tightening, thereby improving the performance. In addition, through holes are set to facilitate the passage of wires through the inside during use and installation, providing certain convenience for installation and construction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient short-head sleeve bolt, comprising a boss, a short-head bolt fixedly connected to the center of the upper end face of the boss, a connecting sleeve fixedly connected to the center of the lower end face of the boss, a groove provided at the center of the upper end face of the short-head bolt, a through hole provided at the center of the lower inner wall of the groove, the lower end of the through hole penetrating the lower inner wall of the groove, the upper end face of the boss and the upper end face of the connecting sleeve and extending to the lower end, three wire harness blocks fixedly connected to the upper end of the center of the inner side wall of the through hole, and multiple anti-slip blocks fixedly connected to the six side walls of the short-head bolt respectively;

[0006] The above technical solution effectively solves the problems of interference and simple installation by setting short-headed bolts. At the same time, anti-slip blocks are set on the six side walls of the short-headed bolts to provide a certain friction force to prevent stripping during tightening and improve the performance. In addition, through holes are set to facilitate the wires to pass through the inside during use and installation, which provides certain convenience for installation and construction.

[0007] Furthermore, the wire harness block is made of silicone.

[0008] The above technical solution is relatively friendly to the connecting wires and is less likely to damage the surface of the wires.

[0009] Furthermore, an annular groove is provided at the upper end of the center of the side wall of the connecting sleeve;

[0010] The above technical solution facilitates positioning during installation.

[0011] Furthermore, the lower end of the connecting sleeve is rounded.

[0012] The above technical solution facilitates installation.

[0013] Furthermore, the short-headed bolt, anti-slip block, boss, and connecting sleeve are integrally cast.

[0014] The above technical solution results in a stable, one-piece structure with a long service life.

[0015] Furthermore, the three wire bundles are bonded to the inner wall of the through hole;

[0016] The above technical solutions facilitate processing, production, and assembly, and also make repairs easier after damage.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, by setting a short-headed bolt, the problems of interference and simple installation are effectively solved.

[0019] 2. In this utility model, anti-slip blocks are provided on the six side walls of the short-headed bolt to provide a certain friction force, prevent stripping of threads during tightening, and improve the performance.

[0020] 3. In this utility model, by providing through holes, it is easy for wires to pass through the inside during use and installation, which provides certain convenience for installation and construction. Attached Figure Description
