Description

Technical Field

[0001] This application relates to the field of trailer hitches, and in particular to UTV rear trailer hitches. Background Technology

[0002] All-terrain vehicles (ATVs) are vehicles capable of traversing any terrain, moving freely on surfaces where ordinary vehicles struggle. UTVs (Utility Terrain Vehicles) broadly refer to ATVs, generally known as practical multi-functional ATVs. Their primary transmission system is the engine, a four-wheeled motorized vehicle designed based on its horsepower and torque. These vehicles are simple and practical, with excellent off-road performance. They feature wide tires that increase the contact area with the ground, generating greater friction and reducing the vehicle's pressure on the ground, making them easy to traverse beaches, riverbeds, forest trails, streams, and harsh desert terrain. They can carry people or transport goods.

[0003] Tow hooks are typically installed at the rear of a vehicle and can be used to tow objects or rescue stranded vehicles. U-shaped tow hooks are a common type. Existing U-shaped tow hooks generally consist of a U-shaped hook and a cover to close the opening on the hook. When using the tow hook with the cover open, the cover may interfere with spare tires, spare fuel tanks, rescue tools, or other equipment suspended on the rear of the vehicle, preventing it from opening properly and hindering towing operations.

[0004] Chinese patent application publication number CN213322538U, published on June 1, 2021, entitled "An Inward-Flip Tow Hook," discloses an inward-flip tow hook. It includes a U-shaped arm, a top cover, a tow ball, and an expansion socket located at the front end of the main arm. The inward-flip top cover solves the problem of interference between an upward-flipping top cover and the rear-mounted load-bearing device of a vehicle. However, in this tow hook, the inward-flipping top cover extends into the U-shaped arm, occupying the opening space and the internal space of the U-shaped arm, interfering with the installation of lifting devices inside the U-shaped arm, making it difficult to install large-sized lifting devices. Utility Model Content

[0005] In order to overcome the interference problem between the inner flap trailer hook and the outer flap trailer hook in the prior art when installing the spreader, this application provides a UTV rear trailer hook.

[0028] In one possible implementation, a latch is provided on the end of the pin away from the second R-pin, a connecting piece is provided on the connecting arm, a through hole is provided on the connecting piece, a connecting rope is wound around one end of the second R-pin, and one end of the connecting rope passes through the through hole and is connected to the other end of the latch and the second R-pin in sequence.

[0029] In one possible implementation, the connecting arm includes:

[0030] The first connecting plate is fixedly installed on the rear of the vehicle;

[0031] The second connecting plate is fixedly mounted on the first connecting plate;

[0032] The third connecting plate is fixedly installed on the rear of the vehicle;

[0047] Reference Figure 1-6The UTV rear tow hook includes a connecting arm 1, a towing ball 2, an inclined plate 3, a pin 4, and a stop. The connecting arm 1 has an opening 5 at its upper end. The towing ball 2 is fixedly mounted on the connecting arm 1 and located at one end of the opening 5. The inclined plate 3 is fixedly mounted on the connecting arm 1. The pin 4 passes through the connecting arm 1 and the inclined plate 3, facilitating the pulling of items. The stop is rotatably mounted on the connecting arm 1 and located at the other end of the opening 5. The stop rotates horizontally relative to the connecting arm 1 and has a closed state and an open state. When the stop is in the closed state, the connecting arm 1, the towing ball 2, and the stop form a closed-loop connecting cavity 6. When the stop is in the open state, one end of the stop moves away from the opening 5. When the stop is in the closed state, it overcomes the interference problem existing in the installation of lifting gear in the internal and external flip-top tow hooks of the prior art. When the stop is in the open state, it will not interfere with the external lifting gear extending into the connecting cavity 6, nor will it interfere with the structure of the UTV rear, facilitating the use of the tow hook.

[0048] The stop includes a fixing block 7, a first pin 8, and a baffle 9. The fixing block 7 is fixedly mounted on the connecting arm 1, the first pin 8 is rotatably mounted on the fixing block 7, and the baffle 9 is fixedly mounted on the first pin 8.
