Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rope tensioner technology, specifically relating to an improved truck rope tensioner. Background Technology
[0002] Truck rope tensioners are a key device widely used in the freight transportation industry to ensure the stability and safety of goods during transportation. Their main function is to secure goods by tensioning ropes to prevent them from moving or tipping over during transportation. These rope tensioners typically include a complex locking mechanism that can achieve three working states: tightening, loosening, and maintaining tension, thereby adapting to different cargo loading and securing needs.
[0003] Traditional truck rope tensioner designs employ a worm gear mechanism to perform the aforementioned operations. Specifically, during tightening, the bolt, due to the thrust of the worm gear, has its front end pressed against the housing to achieve the desired tension. In the locked state, the reaction force of the worm gear propels the worm forward, causing its end face to directly act on the housing. However, this design has certain limitations: because the housing material is less hard than the worm gear, after prolonged use, the housing will produce iron filings due to wear. These iron filings not only affect the normal rotation of the worm gear but may also reduce the overall efficiency of the rope tensioner and even cause safety issues. Utility Model Content
[0004] The present invention aims to provide an improved truck rope tensioner to solve the technical problem that existing truck rope tensioners cause wear and tear on the truck body during use.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] An improved truck rope tensioner includes a housing and a locking bolt. The housing has an installation port, and a worm gear and a worm sleeve are installed inside the installation port. The worm gear can rotate inside the installation port, and the worm sleeve meshes with the worm gear.
[0007] The housing also has an insertion hole that passes through the mounting opening. The locking bolt is inserted into the insertion hole, and the worm gear is sleeved on the locking bolt. A wear-resistant washer is also installed on the locking bolt, and the wear-resistant washer is in close contact with the inner wall of the mounting opening. The housing also has a pin hole in which a positioning pin is inserted. The end of the locking bolt has an annular groove, and the positioning pin is located in the annular groove.
[0008] Furthermore, the worm gear sleeve and the locking bolt are engaged by a key.
[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows: This improved truck rope tensioner significantly enhances the durability and stability of the equipment by introducing wear-resistant washers and positioning pins. Specifically, the wear-resistant washers are installed on the locking bolts and closely adhere to the inner wall of the mounting opening, effectively preventing wear caused by direct contact between the worm gear sleeve end face and the housing. This reduces the risk of the turbine not rotating smoothly due to iron filings generated from wear, thereby extending the service life of the equipment and improving work efficiency. Furthermore, the positioning pins precisely limit the locking bolts, preventing displacement during use and ensuring no unnecessary friction occurs between the worm gear sleeve and the housing, further protecting the internal components. This utility model not only solves key problems in traditional designs but also enhances the safety and reliability of cargo transportation, reduces maintenance costs, and provides users with a more efficient and stable cargo securing solution.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] The present invention will be further described in detail below with reference to the embodiments.
[0016] like Figure 1-3 As shown, a specific embodiment of the improved truck rope tensioner provided by this utility model is as follows:
[0017] An improved truck rope tensioner includes a housing 1 and a locking bolt 2. The housing 1 has an installation port 3, and a worm wheel 4 and a worm sleeve 5 are installed in the installation port 3. The worm wheel 4 can rotate in the installation port 3, and the worm sleeve 5 meshes with the worm wheel 4.
[0018] An insertion hole is provided on the housing 1, which passes through the mounting opening 3. The locking bolt 2 is inserted into the insertion hole, and the worm gear sleeve 5 is set on the locking bolt 2. A wear-resistant washer 6 is also installed on the locking bolt 2, and the wear-resistant washer 6 is in close contact with the inner wall of the mounting opening 3. A pin hole is provided on the housing 1, and a positioning pin 7 is inserted into the pin hole. An annular groove 8 is provided at the end of the locking bolt 2, and the positioning pin 7 is located in the annular groove 8.
[0019] In this embodiment, a positioning pin 7 is inserted into the housing 1. The positioning pin 7 is also located in the annular groove 8 at the end of the locking bolt 2, which can limit the locking bolt 2 and prevent the locking bolt 2 from shifting, causing the worm sleeve 5 to contact the inner wall of the housing 1 of the mounting port 3. The wear-resistant washer 6 can also prevent the end face of the worm sleeve 5 from contacting the housing 1, thus playing a role in isolation and protection.
[0020] It should be noted that, in this document, terms such as “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
