[0005] In view of the problems existing in the prior art, the utility model provides a limiting mechanism for rescue traction device which is easy to connect and has high safety.

[0006] The technical scheme of the utility model is:

[0007] A limiting mechanism for rescue traction device, comprising:

[0008] A moving part connected to the corresponding rescue vehicle;

[0009] A swing part rotatably connected to the moving part and forming a rotation point, the two ends of the swing part extending away from the rotation point to form a swing part and a limiting part, the moving part including a limiting assembly corresponding to the front side of the limiting part, a spring connected to the limiting part; When the swing part moves backward, the swing part is first pushed forward by the corresponding towing structure and then reset by the spring to the rear side of the towing structure, and is limited by the abutting action of the limiting part and the limiting assembly.

[0010] Further, the moving piece extends forward and backward and is connected to the rescue vehicle through the guide piece at the front end, the swinging piece extends left and right at the rear end of the moving piece, and the swinging part corresponds to the guide piece at the front side; the swinging part, the moving piece and the guide piece form a limiting area with a left-right direction single-side opening.

[0011] Further, the moving piece and the swinging piece are both provided with two and are distributed left and right symmetrically, the guide piece is connected to the rescue vehicle through horizontal rotation of the rotating seat, the front ends of the two moving pieces are horizontally slidably sleeved on the left and right sides of the guide piece, the inner side of the moving piece is horizontally rotatably provided with a guide wheel abutting against the rear side of the guide piece, the rear ends of the two moving pieces are folded and extended towards the left and right opposite sides and are provided with the rotating points, the two swinging pieces are rotatably connected to the two rotating points respectively, and the front side of the guide piece is provided with an adjusting driving device connecting the front end parts of the two moving pieces.

[0012] Further, the limiting part includes an abutting frame which is arranged to be bent towards the rear side and is provided with an abutting wheel at the end which is horizontally rotatable, and a connecting plate which is arranged inside the abutting frame, the limiting assembly includes an abutting column which is vertically arranged on the front side of the end of the abutting frame close to the rotating point, and an abutting side wall which extends to the front side of the abutting wheel, and the front and rear ends of the spring are connected to the inner wall of the moving piece and the connecting plate respectively.

[0013] Further, the middle part of the rear side of the guide piece is provided with a lifting plate which is protruded rearward.

[0014] Further, the towed structure is the tire of the corresponding faulty vehicle, and the front side of the swinging part is arranged to be inclined to form an abutting surface which is low in front and high in back.

[0015] Therefore, the beneficial effects of the utility model are:

[0016] 1. By adding the limiting mechanism, when rescue traction is needed, the swinging part is allowed to be displaced forward by the towed structure, and then the swinging part is reset by the spring and is limited to displace backward by the abutting action of the limiting part and the limiting assembly, so that the limiting hook is arranged on the rear bottom side of the towed structure, thereby limiting and fixing the towed structure of the faulty vehicle, when the rescue vehicle moves forward, the faulty vehicle can be moved forward by the limiting and fixing of the towed structure by the limiting mechanism, thereby the faulty vehicle can be quickly and conveniently limited and fixed by the limiting mechanism without manual operation, the connection between the rescue vehicle and the faulty vehicle can be easily completed at dangerous fault sites such as sea surface and mud, the rescue difficulty is reduced, the rescue efficiency is improved, and the safety of rescue personnel in rescue operation is improved.

[0017] 2. As the rescue vehicle moves backward, the limiting mechanism moves backward as well. The swinging part, under the forward pressure of the wheels or other towed structures of the disabled vehicle, swings forward to allow the towed structure to move into the limiting zone. Then, the swinging part is pulled back by a spring and its backward swing is limited by the contact action of the limiting part and the limiting assembly. The limiting stop is positioned on the rear bottom side of the towed structure, thus limiting and fixing the towed structure of the disabled vehicle. When the rescue vehicle moves forward, the limiting mechanism can use this fixing mechanism to move the disabled vehicle forward. The addition of a guide member creates a limiting zone that can open on one side in the left or right direction. When the swinging part of the limiting mechanism is positioned at the rear of the towed structure, the guide member can be positioned at the front of the towed structure to limit its forward and backward movement within the limiting zone. This improves the limiting stability of the limiting mechanism on the towed structure and enhances the stability of the rescue vehicle's movement during rescue towing operations.

[0018] 3. By setting up symmetrically distributed moving and swinging components, the limiting zone is increased to two symmetrically positioned areas. When the disabled vehicle is a car, the two limiting zones can simultaneously limit and fix the two front wheels or two rear wheels of the car, thereby improving the stability of the rescue towing device. The rotating seat allows the limiting mechanism to turn when the rescue vehicle turns, improving the stability of the rescue towing device during operation. Furthermore, the distance between the two limiting zones can be adjusted by adjusting the drive of the drive device to adapt to different car tire widths, improving the adaptability of the rescue towing device.

[0019] 4. By bending the limiting part and adding the abutting wheel, the limiting part is simultaneously abutted by both the abutting post and the abutting side wall. Furthermore, a triangular structure is formed between the abutting wheel, the abutting post, and the rotation point, which improves the limiting support strength of the moving part for the limiting part, improves the limiting strength of the swinging part, and thus improves the limiting strength of the limiting area for the dragged structure.

[0020] 5. By adding a lifting plate, when the limiting mechanism lifts the car tire, the lifting plate can be placed against the bottom of the car, increasing the contact point and area between the limiting mechanism and the car, thus improving the stability of the limiting mechanism when lifting the car tire.

[0021] 6. By setting the contact surface, the swing part can be adapted to be tilted and abutted against the rear bottom side of the tire, which increases the contact area between the two and improves the stability of the swing part pushing the tire forward. Attached Figure Description
