Description

Technical Field

[0001] The utility model belongs to the technical field of trailers, and in particular relates to a clevis ball head trailer hook. Background Art

[0002] With the vigorous development of my country's economy and the continuous maturity of automobile production technology, the production and sales of automobiles have increased year by year. Mature production technology has reduced the cost and price of automobiles, so more and more units and individuals have purchased automobiles, especially the number of private cars has been greatly increased. The prosperity of the automobile industry has driven the development of automobile peripheral products.

[0003] Most vehicles are equipped with a trailer at the rear to facilitate towing other vehicles or transport equipment. However, an ordinary trailer is just a ring with a small tensile bearing capacity and poor adaptability to a tow rope or tow bar, and structural improvements are needed. Utility Model Content

[0004] The utility model aims to provide a clevis ball head trailer hook, which solves the technical problems of poor adaptability and single structure of the existing trailer device.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A ram-horn ball trailer hook comprises a tow bar, which is a square tube structure and has a plurality of lock holes. A double-headed hook is fixed at one end of the tow bar, and the double-headed hook is composed of two groups of hooks, which are symmetrically arranged about the tow bar. A sliding hook tongue is arranged at the opening of each hook, and one end of the sliding hook tongue is hinged to the hook through an axle pin, and a torsion spring is arranged on the axle pin. The torsion spring acts on the sliding hook tongue to make the other end of the sliding hook tongue contact the inner wall of the hook.

[0007] The double-head hook is provided with a through hole, a ball bolt is passed through the through hole, the ball bolt is fixed on the double-head hook through a nut, and a spring washer is also sleeved on the ball bolt.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the utility model adopts a tow bar with a square tube structure, which has better strength and rigidity than the traditional round trailer device and can withstand greater pulling force; the horn-shaped design of the double-headed hook enables it to mount the towed vehicle or device more firmly, and the two symmetrical hooks increase the stability and reliability of the overall structure, and the sliding hook tongue and its torsion spring mechanism ensure the safety of the connection and prevent accidental falling off during towing; the utility model allows the user to quickly insert the tow bar into the 2-inch square opening at the rear of the vehicle and fix it with a locking pin, which is easy and quick to operate, and the design of the lock hole facilitates the selection of a suitable locking pin position according to different towing requirements, thereby increasing flexibility; the standard size of 2 inches ensures the compatibility of the trailer hook with most vehicle rear interfaces and expands its application range; the selection of components such as the square tube structure, ball studs and spring washers improves the durability of the entire trailer hook system and reduces maintenance costs.

[0009] In summary, this new type of clevis ball trailer hook not only improves the safety and stability during towing, but also simplifies the installation process and enhances the versatility and durability of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] The present invention is further described in detail below in conjunction with the embodiments.

[0015] like Figure 1 and Figure 2 As shown, a specific embodiment of a clevis ball trailer hook provided by the utility model:

[0016] A ram's horn ball trailer hook comprises a tow bar 1, which is a square tube structure. A plurality of lock holes 2 are provided on the tow bar 1. A double-headed hook 3 is fixed at one end of the tow bar 1. The double-headed hook 3 is in a ram's horn shape. The double-headed hook 3 is composed of two groups of hooks. The two groups of hooks are symmetrically arranged about the tow bar 1. A sliding hook tongue piece 4 is provided at the opening of each hook. One end of the sliding hook tongue piece 4 is hinged to the hook through an axle pin 5. A torsion spring is provided on the axle pin 5. The torsion spring acts on the sliding hook tongue piece 4 so that the other end of the sliding hook tongue piece 4 abuts against the inner wall of the hook.

[0017] The double-headed hook 3 is provided with a through hole, in which a ball stud 6 is passed, and the ball stud 6 is fixed to the double-headed hook 3 by a nut, and a spring washer 7 is also mounted on the ball stud 6.

[0018] When using the clevis ball trailer hook of this embodiment, first insert the 2-inch ball bolt 6 into the through hole of the double-headed hook 3, put on the spring washer 7 and tighten the nut, then insert the tow bar 1 into the 2-inch square opening at the rear of the vehicle, then open the trailer lock, insert the lock pin into one of the lock holes 2, press the lock core until it is flush, and cover it with the rubber sleeve protective cover.

[0019] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
