Existing automotive couplers generally do not have an anti-rope-detachment device. During actual use, the towing rope may separate from the automotive coupler, thus causing great potential safety hazards and resulting in poor use effects of existing automotive couplers. Therefore, it is necessary to design and transform the coupler connection device to effectively prevent the phenomenon of poor anti-rope-detachment effect. Summary of the Utility Model

When towing a vehicle, the towing rope is tied to the surface of the automotive coupler. Existing automotive couplers generally do not have an anti-rope-detachment device. During actual use, the towing rope may separate from the automotive coupler, thus causing great potential safety hazards and resulting in poor use effects of existing automotive couplers.
[0005] To achieve the above purpose, the present utility model provides the following technical solution: A coupler connection device includes a U-shaped frame. Both the front side and the rear side of the top of the U-shaped frame are fixedly connected with support blocks. An anti-detachment rod is movably connected inside the support block.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0020] As shown in Figures 1 to 4 , a coupler connection device includes a U-shaped frame 1. Support blocks 2 are fixedly connected to both the front side and the rear side of the top of the U-shaped frame 1. An anti-disengagement rod 3 is movably connected inside the support block 2. The anti-disengagement rod 3 is movably connected to the U-shaped frame 1. A fixed block 7 is fixedly connected to the bottom of the anti-disengagement rod 3. A card slot is provided on the left side of the fixed block 7. An activity frame 4 is movably connected inside the U-shaped frame 1. The right side of the activity frame 4 extends to the right side of the U-shaped frame 1 and is fixedly connected to a disc 5. A tension spring 6 is fixedly connected to the left side of the disc 5. The tension spring 6 is fixedly connected to the U-shaped frame 1. A locking frame 8 is fixedly connected to the top of the activity frame 4.
[0021] Referring to Figure 1 , a reinforcing block 9 is fixedly connected to the left side of the U-shaped frame 1. A round rod 10 is fixedly connected to the left side of the reinforcing block 9. A thread groove is provided on the surface of the round rod 10.
[0022] As a technical optimization scheme of the present invention, through the arrangement of the reinforcing block 9 and the round rod 10, the operator can thread-connect the round rod 10 to the coupler connection part of the vehicle, and then connect the device to the vehicle.
[0023] Referring to Figure 1 , Figure 2 and Figure 4 , the left side of the activity frame 4 is arc-shaped. An abrasion-resistant and anti-slip pad 13 is fixedly connected to the surface of the activity frame 4. Anti-slip lines are provided on the surface of the abrasion-resistant and anti-slip pad 13, and the number of anti-slip lines is several. The abrasion-resistant and anti-slip pad 13 is made of rubber material.
[0024] As a technical optimization scheme of the present invention, through the arc-shaped arrangement of the left side of the activity frame 4, when the activity frame 4 contacts the towing rope, the activity frame 4 can apply a force inclined downward to the towing rope, thereby avoiding the phenomenon of the towing rope moving upward and causing the hook to come off. Through the arrangement of the abrasion-resistant and anti-slip pad 13, the friction between the towing rope and the activity frame 4 can be increased, thereby improving the towing effect of the device.
[0025] Referring to Figure 1 and Figure 3 , torsion springs 11 are fixedly connected to both the front side and the rear side of the anti-disengagement rod 3. The torsion springs 11 are fixedly connected to the support block 2. Anti-rust paint is sprayed on the surfaces of the torsion springs 11 and the tension spring 6. A handle 12 is fixedly connected to the top of the anti-disengagement rod 3.
[0026] As a technical optimization solution of the present utility model, through the arrangement of the torsion spring 11, when the operator rotates the anti-disengagement rod 3 counterclockwise, the torsion spring 11 will be rotated. When the operator releases the anti-disengagement rod 3, under the action of the torsion spring 11, the anti-disengagement rod 3 rotates clockwise until the anti-disengagement rod 3 is movably connected to the U-shaped frame 1, and the anti-disengagement rod 3 is reset.
[0027] Reference Figure 1 And Figure 4 Refer to
[0028] As a technical optimization solution of the present utility model, through the arrangement of the mounting block 14 and the bolt 15, when the device needs to tow a car with a relatively large mass, in order to further improve the anti-disengagement effect of the device, the operator can tighten the bolt 15 so that the bolt 15 is threadedly connected to the U-shaped frame 1, thereby further locking the anti-disengagement rod 3.
[0029] Reference Figure 1 、 Figure 3 And Figure 4 The surface of the U-shaped frame 1 is provided with a guiding bevel angle.
[0030] As a technical optimization solution of the present utility model, by providing a guiding bevel angle on the surface of the U-shaped frame 1, it is possible to prevent the towing rope from contacting the edge of the U-shaped frame 1 and causing damage to the towing rope.
[0031] The working principle and usage process of the present utility model: When in use, the operator first connects the device to the car. The operator rotates the anti-disengagement rod 3 counterclockwise, then puts the towing rope inside the U-shaped frame 1, and then the operator releases the anti-disengagement rod 3. Under the action of the torsion spring 11, the anti-disengagement rod 3 is reset. Then the external towing component pulls the towing rope, and the towing rope presses the movable frame 4, thereby driving the movable frame 4 to move to the right. When the movable frame 4 moves to the right, it drives the locking frame 8 to move to the right, so that the locking frame 8 is inserted into the inside of the card slot, thereby automatically locking the anti-disengagement rod 3, and thus preventing the towing rope from separating from the device. Similarly, when the operator needs to disassemble the towing rope, the operator releases the extrusion of the towing rope on the movable frame 4, so that the movable frame 4 moves to the left, causing the locking frame 8 to separate from the card slot, thereby unlocking the anti-disengagement rod 3. Then the operator can directly open the anti-disengagement rod 3, and thus take out the towing rope.
