Description

Technical Field

[0001] The utility model relates to the technical field of vehicle towing hooks, in particular to a novel anti-dropping traction structure. Background Art

[0002] The existing vehicle tow hook refers to a device on the vehicle used to tow or connect other vehicles, carriages or objects. It is usually made of steel or other strong materials and has sufficient strength and durability. The background technology of the tow hook involves fields such as engineering, material science and mechanical design to ensure that it can safely and reliably perform connection and towing tasks. This involves suitable connection mechanisms, strength analysis, anti-corrosion technology and designs that comply with relevant regulations and standards. In addition, the existing vehicle tow hook may experience wear, corrosion or other damage after long-term use or under harsh conditions, affecting its strength and durability; the connection mechanism of the tow hook may have design or manufacturing defects, resulting in unsafe connection and even the risk of the trailer falling off; the tow hook design between different vehicle models may not be uniform enough, resulting in some vehicles being unable to easily connect to other vehicles or trailers; different regions and countries may have different tow hook safety standards, resulting in possible mismatches during international interconnection; incorrect driving behavior, such as sudden braking or acceleration, may cause additional stress on the tow hook and increase the risk of damage.

[0003] After searching, the existing patent (publication number: CN217969149U) discloses a trailer tractor, which relates to the technical field of vehicle towing and traction equipment, specifically a trailer tractor, including a connecting plate, the front end and the rear end of the left side of the connecting plate are both provided with bolt grooves, the front end of the connecting plate is fixedly connected with a driving device, the outer surface of the output end of the driving device is fixedly connected with a drag plate, and the inner surface of the right bottom of the drag plate is movably installed with a first moving component. Through the use of a driving motor, the driving rod can drive the drag plate to rotate, and then the drag plate has two states, horizontal and vertical. When the drag plate is in a horizontal state, the user can connect it with the connecting ring through the traction device on the car, and then the trailer can tow the car through the device, and when the drag plate is in a vertical state, the horizontal length of the trailer installed with the device can be reduced, and then the movement of the trailer can be facilitated, thereby improving the practicality of the device.

[0004] However, the existing new anti-pin dropout traction structure may have design or manufacturing defects during trailer towing, resulting in unsafe connection. When the vehicle is towing a trailer, the traction structure may easily fall off accidentally, and may even cause the risk of the trailer falling off, which greatly reduces the practicality of the traction structure.

[0005] Therefore, a novel anti-pin-off traction structure is proposed to address the above problems. Utility Model Content

[0015] As a preferred solution, the adaptive device forms pressure between the towing hook at all times to prevent the traditional towing hook from being worn, corroded or damaged, which affects its strength and durability and causes the towing equipment to fall off.

[0016] The utility model provides a novel anti-pin-off traction structure, which has the following beneficial effects:

[0017] (1) The new anti-drop-pin traction structure is provided with a first spring, an angle steel and an adaptive device. When the new anti-drop-pin traction structure is working to tow a trailer, the anti-drop-pin type supporting hook maintains tension with the supporting hook through the adaptive device, which effectively prevents the connection mechanism of the towing hook from having design or manufacturing defects, resulting in unsafe connection, and even the risk of the trailer falling off. The adaptive device always forms pressure between the supporting hook, preventing the traditional supporting hook from being worn, corroded or otherwise damaged, which affects its strength and durability, and causes the towing equipment to fall off.
