Description

Technical Field

[0001] The present application relates to the technical field of trailer tools, and in particular to a trailer ball with a rope that can prevent it from falling off. Background Art

[0002] A trailer ball is a spherical component installed on the trailer hook at the rear end of a car and used to connect other towing vehicles. It nests with the trailer ball cover of the towing RV or vehicle to form a freely movable joint connection structure. It is also used to connect ropes for mechanical traction and other towing purposes.

[0003] At present, a trailer ball is usually a device used to tow a rear-hook load. It can also be used in conjunction with a towing rope to tow a vehicle in the absence of a trailer hook. Since the trailer ball is not as strong as the trailer hook, if the instantaneous pulling force when towing the vehicle is too large, it may easily cause a slight bend at the connection point between the ball head and the vertical rod, which may cause the ball head to be unable to be used normally. In addition, since the ball head is spherical, the tow rope may easily fall off the ball head. Utility Model Content

[0004] The purpose of the present application is to solve the problem in the prior art that since the trailer ball is not as strong as the trailer hook, if the instantaneous pulling force when towing the vehicle is too large, it is easy to cause a slight bending phenomenon at the connection point between the ball head and the vertical rod, which may cause the ball head to be unable to be used normally, and since the ball head is spherical, the tow rope is also easy to fall off the ball head, and a trailer ball with a rope anti-falling off phenomenon is proposed.

[0005] In order to achieve the above purpose, this application adopts the following technical solutions:

[0006] A trailer ball with a rope that prevents it from falling off comprises a mounting plate, a ball head is arranged above the mounting plate, a locking assembly is installed together with the ball head and the mounting plate, a side wall of the ball head is provided with an annular rope groove, and the annular rope groove is arranged obliquely, a limiting assembly is installed on the groove wall of the annular rope groove, a horizontal guide wheel is arranged on one side of the ball head, a supporting assembly is installed on the locking assembly, and the horizontal guide wheel is connected to the supporting assembly.

[0007] Preferably, the locking assembly includes a locking rod integrally formed at the lower end of the ball head, the rod wall of the locking rod is slidably inserted into the end surface of the mounting plate, the rod wall of the locking rod is fixedly sleeved with a fixing sleeve, a locking nut is provided below the fixing sleeve, and the locking nut is threadedly connected to the rod wall of the locking rod.

[0012] Compared with the prior art, the present application provides a trailer ball with a rope that prevents it from falling off, which has the following beneficial effects:

[0013] 1. The trailer ball with rope anti-falling can clamp the rope by using the annular rope groove to prevent the rope from falling directly along the arc surface of the ball head when towing the vehicle through the cooperation of the mounting plate, the ball head, the annular rope groove and the horizontal guide wheel, and the horizontal pulling force on the trailer ball can be decomposed into a part of the upward pulling force by using the tilting effect of the horizontal guide wheel and the annular rope groove, so as to avoid the phenomenon of damage to the trailer ball caused by excessive instantaneous dragging force as much as possible.

[0014] 2. The trailer ball with rope anti-slip can facilitate the fixed installation between the ball head and the mounting plate through the provided locking assembly, and can prevent the rope from falling off from the annular rope groove through the provided fiber assembly, and can stably support the horizontal guide wheel through the provided support assembly.

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0021] Reference Figure 1-3 A trailer ball with a rope anti-slipping function comprises a mounting plate 1, a ball head 2 is arranged above the mounting plate 1, a locking assembly is installed together with the ball head 2 and the mounting plate 1, a side wall of the ball head 2 is provided with an annular rope groove 3, and the annular rope groove 3 is arranged obliquely, a limiting assembly is installed on the groove wall of the annular rope groove 3, a horizontal guide wheel 4 is arranged on one side of the ball head 2, a supporting assembly is installed on the locking assembly, and the horizontal guide wheel 4 is connected to the supporting assembly.

[0022] The locking assembly includes a locking rod 5 integrally formed at the lower end of the ball head 2, the rod wall of the locking rod 5 is slidably inserted into the end surface of the mounting plate 1, the rod wall of the locking rod 5 is fixedly sleeved with a fixing sleeve 6, a locking nut 7 is provided below the fixing sleeve 6, and the locking nut 7 is threadedly connected to the rod wall of the locking rod 5. Through this arrangement, the ball head 2 and the mounting plate 1 can be easily fixed and locked.

[0023] The limiting assembly includes a mounting groove 8 opened on the side wall of the ball head 2, the groove wall of the mounting groove 8 is slidably connected to a limiting slide rod 9, the groove wall of the annular rope groove 3 is provided with a plug-in groove 10 matching the limiting slide rod 9, a pull head 11 is fixedly installed on the rod end of the limiting slide rod 9, and a spring 12 is fixedly provided between the side wall of the pull head 11 and the groove wall of the mounting groove 8. Through this arrangement, the rope can be prevented from falling off from the annular rope groove 3.

[0024] The supporting assembly includes a rotating plate 13 hinged to the two side walls of the fixing sleeve 6, and the horizontal guide wheel 4 is rotatably arranged between the two rotating plates 13. The side walls of the two rotating plates 13 are threadedly connected with fixing bolts 16, and the two fixing bolts 16 are threadedly connected to the side walls of the fixing sleeve 6. Through the fixing bolts 16, the rotating plate 13 can be locked and fixed after being rotated.

[0025] The upper ends of the side walls of the two rotating plates 13 are commonly threadedly connected with a limiting bolt 14, and the horizontal guide wheel 4 is arranged below the limiting bolt 14. The limiting bolt 14 can be used to limit the rope to prevent the rope from falling off the horizontal guide wheel 4.

[0026] The side walls of the two rotating plates 13 are fixedly embedded with magnetic blocks 15, and the two magnetic blocks 15 are magnetically connected to the mounting plate 1. Through this arrangement, the rotating plates 13 can be put down when the vehicle is not towed. The mounting plate 1 and the magnetic blocks 15 can be used to magnetically fix the rotating plates 13, thereby improving the stability of the rotating plates 13.

[0027] In the present application, when in use, when it is necessary to tow the vehicle, one end of the tow rope is inserted into the annular rope groove 3 of the ball head 2, and the end of the tow rope is bolted and fixed together with the rope body. Then, the rope body of the tow rope is passed through the horizontal guide wheel 4. During towing, since the tow rope clamp is in the annular rope groove 3, the tow rope is not easy to fall off from the ball head 2. Moreover, due to the horizontal guiding effect of the horizontal guide wheel 4 and the inclined design of the annular rope groove 3, when towing the vehicle, the pulling force applied by the tow rope to the ball head 2 will be decomposed into two parts, one part is the horizontal pulling force, and the other part is the vertical part, so that the horizontal pulling force can be reduced, and then the instantaneous excessive pulling force can be avoided as much as possible to cause damage to the ball head 2.

[0028] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and utility model concept of the present application, which should be covered by the protection scope of the present application.
