Background

The trailer ball is a part with a spherical structure, which is arranged on a trailer hook at the rear end of an automobile and is used for connecting other trailer vehicles, the trailer ball is nested and matched with a trailer ball cover of a trailer car or a vehicle to form a freely movable joint connecting structure, and the trailer ball is also used for connecting ropes for dragging purposes such as mechanical traction and the like.

The utility model discloses a patent for CN216683961U, it discloses a joint strength is good and take up an area of the little trailer ball seat in space, including the curved boom and the trailer ball of L shape, the trailer ball includes the linking arm of bulb and bulb below, be provided with parallel arrangement's between the riser of curved boom and the linking arm, lower swing arm, on, the both ends of lower swing arm are respectively through articulated shaft and riser, the linking arm is articulated, threaded hole has been seted up on the bottom plate of curved boom, the bolt passes behind the threaded hole below and offsets with the linking arm lower extreme of bulb, whole trailer ball seat is less in the occupation space of horizontal direction, and better strength is convenient for install at the rear of a vehicle.

However, the equipment has other problems that when the trailer ball is towed by a non-horizontal plane such as a slope or in a field severe road environment, the rear part of the trailer ball is not connected with a rigid ball cover and needs to be towed by a flexible steel wire rope instead, when the trailer ball is towed by the steel wire rope, the steel wire rope buckle is easy to separate from the ball head under the action of heavy weight because the ball head is arc-shaped, the stress of a towed primer at the rear part is interrupted, and potential safety hazards are caused.

SUMMERY OF THE UTILITY MODEL

The invention aims to provide a rope anti-drop trailer ball to solve the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme: a hitch ball for preventing escape of a rope, comprising:

the base is used for supporting, and the right end of the upper surface of the base is fixedly provided with a hinge bulge;

the arc-shaped ball head is fixedly connected to the middle part of the upper end surface of the base and used for traction and suspension;

the mounting assembly is fixedly arranged at the lower end of the base and is used for integrally fixing the device on a traction vehicle;

the anti-falling component is hinged to the hinged protrusion and used for preventing the traction rope at the hanging position from being separated.

In the technical scheme, when vehicle traction and field vehicle rescue are carried out, the distance between the vehicle to be dragged and the traction rescue vehicle is usually far, and the far traction distance ensures that a subsequent vehicle can not be connected to the ball head of a front vehicle through the ball sleeve; need be on the bulb of traction vehicle afterbody with follow-up rope cover for the vehicle this moment, at this moment earlier pass through the trailer ball and fix the afterbody to traction vehicle to the installation component, then buckle the rope ring on the arc bulb, because rope angle constantly changes when pulling, often let the rope break away from the arc bulb under external force, buckle the anticreep subassembly into on the arc bulb this moment, form the closed loop, make the rope can't break away from the arc bulb no matter what angle pulling, ensure not struggled away at the traction in-process rope to rescue vehicle, guarantee that the safety of rescue goes on.

In the above technical solution, further, the anti-dropping assembly includes:

the two hinge blocks are provided, the upper ends of the two hinge blocks are provided with through holes, and hinge pins are hinged at the through holes;
