[0023] In the drawings: 1, towing seat body; 2, towing head; 3, square tube; 4, insertion column; 5, handle; 6, first fixing screw; 7, base; 8, second fixing screw; 9, mounting hole; 10, fan-shaped frame; 11, rotating shaft; 12, insertion hole; 13, extrusion spring; 14, receiving groove. Specific implementation

[0024] The present application provides a Figs. 1-2The utility model provides an RV tow hitch with locking function, comprising: a tow hitch body 1 and a tow head 2, the tow head 2 is installed to one end of the tow hitch body 1, the tow hitch body 1 is the core component of the whole RV tow hitch, and it provides structural support and connection base for the whole device. The tow hitch body 1 is usually made of high-strength steel to ensure its stability and durability during use. The tow head 2 is the key component of connecting the towing vehicle. The tow head 2 usually adopts a standard tow interface design to ensure compatibility with various towing vehicles.

[0025] The tow hitch body 1 is provided with moving wheels on both sides, and the tow head 2 is connected with the towing vehicle.

[0026] The square tube 3 is fixed near the direction of the tow head 2 of the tow hitch body 1, the square tube 3 is slidably connected with the plug column 4 inside, the bottom end of the plug column 4 is fixed with the base 7, and the base 7 is in contact with the ground.

[0027] The plug column 4 slides up and down in the square tube 3, so as to adjust the height of the base 7 to adapt to different ground conditions and use requirements. The base 7 is in contact with the ground to provide stable support. When the base 7 is in contact with the ground, the contact area with the ground is increased to increase the friction, so as to lock the tow hitch body 1 and prevent the tow hitch body 1 from moving.

[0028] A plurality of mounting holes 9 are equidistantly arranged along the height direction of the plug column 4, the first fixing screw 6 is arranged outside the square tube 3, one end of the first fixing screw 6 is matched with the mounting hole 9 in the corresponding position, and the first fixing screw 6 is screwed into the mounting hole 9 in the corresponding position, so as to fix the plug column 4 at the required height position. This design not only provides flexibility for height adjustment, but also ensures the stability of the plug column 4 during use.

[0029] The base 7 is provided with a receiving groove 14 at the bottom end, a fan-shaped frame 10 is rotatably connected in the receiving groove 14, the large edge of the fan-shaped frame 10 is arranged away from the tow hitch body 1, the second fixing screw 8 is fixed outside the base 7, and a plurality of insertion holes 12 are arranged along the arc direction of the large edge of the fan-shaped frame 10.

[0030] One end of the second fixing screw 8 is matched with the insertion hole 12 in the corresponding position, and the extrusion spring 13 is fixedly connected between the top end of the fan-shaped frame 10 and the top end in the receiving groove 14.

[0031] In the actual operation of the utility model, when the height of the plug column 4 is adjusted and the one end of the tow hitch body 1 is raised, only one side of the base 7 is in contact with the ground. At this time, the bottom of the fan-shaped frame 10 can be stretched out of the receiving groove 14 through the elastic force of the extrusion spring 13. At this time, the bottom end of the stretched-out fan-shaped frame 10 is flush with the ground, so as to make up for the insufficient contact between the base 7 and the ground, and improve the stability and structural strength of the structure.

[0032] By setting different jacks 12, the support needs of different pull seat bodies 1 can be met, and the position of the fan-shaped frame 10 can be fixed by the second fixing screw 8.

[0033] The small side of the fan-shaped frame 10 is fixed with a rotating shaft 11, and the rotating shaft 11 is rotatably connected to the inner wall of the receiving groove 14.

[0034] The top end of the plug column 4 extends out of the square tube 3, and the top end of the plug column 4 is fixedly connected with a handle 5, which facilitates the user to operate the lifting and adjustment of the plug column 4.
