Description

Technical Field

[0001] The utility model relates to the technical field of recreational vehicles, in particular to a towing mechanism for a recreational vehicle. Background Art

[0002] RV, also known as "home on wheels", has both functions of "house" and "car", but its attribute is still a car. It is a movable type of vehicle with basic facilities necessary for home. RV is a fashionable vehicle introduced from abroad. The home facilities on the vehicle include bedding, stoves, refrigerators, cabinets, sofas and other furniture and electrical appliances. It can be divided into driving area, living area, kitchen area, etc. Trailer RV is a branch of RV. Unlike self-propelled RV, trailer RV has no power of its own and requires an additional vehicle to tow it.

[0007] By adopting the above technical solution, when the tractor moves outside the RV body, the drive rod A on the fixed frame is pulled, and then the drive rod A drives the fixed frame inside the connecting frame to move, and then the drive rod B outside the connecting frame drives the transmission screw to rotate, and then the wire block outside the transmission screw drives the towing rod to move, so that the towing rod can be adjusted according to the position of the tractor.

[0008] Specifically, the outer side of the towing rod is rotatably connected to a bracket A that drives the limit plate A to rotate, and the outer side of the towing rod is rotatably connected to a bracket B that drives the limit plate B to rotate. The outer side of the limit plate A is threadedly connected to a limit screw that enters into a threaded hole opened on the surface of the limit plate B.

[0009] By adopting the above technical solution, when the positioning block on the towing rod is connected to the tractor, the bracket A and the bracket B outside the towing rod respectively drive the limit plate A and the limit plate B to move, and then the limit plate A and the limit plate B respectively contact the surface of the towing rod of the tractor, and then the limit screw outside the limit plate A is rotated, and then the limit screw enters the threaded hole opened on the surface of the limit plate B, so that the limit plate A and the limit plate B are respectively in close contact with the towing rod on the tractor, thereby improving the stability of the towing of the RV body.

[0010] Specifically, the outer side of the driving rod A is threadedly connected to a threaded sleeve A for fixing the connecting frame.

[0011] By adopting the above technical solution, when the driving rod A drives the connecting frame to move, the threaded sleeve A outside the driving rod A is rotated, and then the threaded sleeve A is in close contact with the surface of the fixing frame, thereby facilitating the fixing of the connecting frame on the driving rod A.

[0012] Specifically, a sliding groove is provided on the inner side of the connecting frame for sliding the sliding block welded on the outer side of the towing rod.

[0013] By adopting the above technical solution, when the towing rod moves, the slider outside the towing rod slides in the slide groove provided in the connecting frame, thereby improving the stability of the movement of the towing rod.

[0014] Specifically, the outer side of the driving rod B is threadedly connected to a threaded sleeve B for fixing the driving rod B.

[0015] By adopting the above technical solution, when the driving rod B drives the transmission screw to rotate, the threaded sleeve B outside the driving rod B is rotated, and then the threaded sleeve B is in close contact with the connecting frame, so that the driving rod B is easily fixed.

[0016] Beneficial effects of the utility model:

[0017] (1) The utility model discloses a towing mechanism for a motorhome. When the tractor moves outside the main body of the motorhome, the driving rod A on the fixed frame is pulled, and then the driving rod A drives the fixed frame inside the connecting frame to move. Then the driving rod B outside the connecting frame drives the transmission screw to rotate, and then the screw block outside the transmission screw drives the towing rod to move, so that the towing rod can be adjusted according to the position of the tractor.

[0018] (2) The utility model discloses a towing mechanism for a motorhome. When the positioning block on the towing rod is connected to the tractor, the bracket A and the bracket B outside the towing rod respectively drive the limit plate A and the limit plate B to move, and then the limit plate A and the limit plate B respectively contact the surface of the towing rod of the tractor, and then the limit screw outside the limit plate A is rotated, and then the limit screw enters the threaded hole provided on the surface of the limit plate B, so that the limit plate A and the limit plate B are respectively in close contact with the towing rod on the tractor, thereby improving the stability of the towing of the motorhome body.
