Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a towing device for automobiles. Background Technology

[0002] Most cars are equipped with tow hooks at the front and rear to secure the tow rope during emergency roadside assistance. Currently, car tow hooks are threaded onto the corresponding positions at the front or rear of the vehicle, with only the hook ring exposed after tightening.

[0003] Application number CN201910973599.X discloses a trailer towing mechanism for automobiles. This mechanism uses a rod sleeved within a fixed cylinder that can slide together with a buffer piston. Hydraulic oil is provided on both sides of the buffer piston, and damping holes are used to achieve buffering performance during rear-end collisions while towing the vehicle. The telescopic rod not only has a long buffer stroke but also has a contact at its end. During towing, the contact is pulled out of the vehicle's bumper to protect the paint from damage caused by a rear-end collision when two vehicles are towing. However, this design has shortcomings. The end of the rod extending out of the fixed cylinder is fixedly connected to the contact, which cannot be disassembled. When the contact wears out, the entire device needs to be replaced, easily leading to resource waste.

[0004] Therefore, we propose a vehicle towing and trailer-trailer device. Utility Model Content

[0005] The main objective of this invention is to provide a towing device for automobiles. The end of the column away from the fixed cylinder is provided with a threaded groove, and the end of the connecting seat away from the clamp is provided with an assembly groove that matches the threaded groove. One end of the column is threadedly connected to the connecting seat, which facilitates the installation and disassembly of the contact body, enabling the contact body to be used flexibly. At the same time, the contact body can be replaced according to the usage requirements, thereby improving its practicality and effectively solving the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A vehicle towing and trailer tractor includes a fixed cylinder, a column, and a contact body. The column is movably connected to one end of the fixed cylinder. The end of the column away from the fixed cylinder is connected to the contact body via a connecting seat and a mounting seat. A mounting seat is fixedly welded to the center of the end of the contact body near the fixed cylinder. A slot for mounting a connecting seat is provided at the center of the end of the mounting seat away from the contact body. A locking element that matches the slot is provided at the center of the end of the connecting seat near the mounting seat. The locking element is located within the slot.

[0008] The column rod is provided with a threaded groove at the end away from the fixed cylinder, and the connecting seat is provided with an assembly groove that matches the threaded groove at the end away from the clamp. One end of the column rod is threadedly connected to the connecting seat, and a positioning component is also sleeved on the outer side of the end of the column rod near the threaded groove.

[0009] The positioning component includes a first arc-shaped component and a second arc-shaped component.

[0010] By adopting the above technical solution, the end of the column rod away from the fixed cylinder is connected to the contact body through the connecting seat and the mounting seat. Through the design of the positioning component, the position of the connecting seat can be limited. With the first bolt, the column rod and the connecting seat are tightly connected. The end of the column rod away from the fixed cylinder is provided with a threaded groove, and the end of the connecting seat away from the clamp is provided with an assembly groove that matches the threaded groove. One end of the column rod is threadedly connected to the connecting seat, which facilitates the installation and disassembly of the contact body.

[0011] The design of the mounting base allows the connector to be detachably connected to the contact body, enabling the contact body to be flexibly disassembled and replaced. In conjunction with the use of the second bolt, the mounting base and the connector can be connected more tightly.

[0012] Specifically, the first arc-shaped component and the second arc-shaped component are arranged opposite to each other, and the first arc-shaped component and the second arc-shaped component together form a circular ring structure.

[0013] Specifically, the first and second arc-shaped parts are snapped together at both ends, and both the first and second arc-shaped parts are fixedly connected to one end of the connecting seat by the first bolt.

[0014] Specifically, the connecting seat has an installation groove at one end near the column rod that is compatible with the first arc-shaped component and the second arc-shaped component.

[0015] Specifically, the diameter of the mounting groove is larger than the diameter of the assembly groove, and the mounting groove is connected to the assembly groove.

[0016] Specifically, the connecting seat is fixedly connected to the end of the mounting seat away from the contact body by a second bolt.

[0017] The beneficial effects of this utility model are:

[0018] (1) The automobile towing and trailer device described in this utility model has a column rod connected to the contact body through a connecting seat and a mounting seat at the end away from the fixed cylinder. The position of the connecting seat can be limited by the design of the positioning component. The column rod and the connecting seat are tightly connected with the first bolt. The column rod is provided with a threaded groove at the end away from the fixed cylinder. The connecting seat is provided with an assembly groove that matches the threaded groove at the end away from the clamp. One end of the column rod is threadedly connected to the connecting seat, which facilitates the installation and disassembly of the contact body, making the contact body flexible to use. At the same time, the contact body can be replaced according to the usage requirements, thereby improving its practicality.

[0019] (2) The automobile towing and trailer device described in this utility model, through the design of the mounting base, allows the connecting base to be detachably connected to the contact body, so that the contact body can be flexibly disassembled and replaced. With the use of the second bolt, the mounting base and the connecting base can be connected more tightly. Attached Figure Description
