Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic structural view of a preferred embodiment of a trailer hitch assembly of the present invention for easy installation; FIG. 2 is a schematic view of the auxiliary tab installation structure of FIG. 1; FIG. 3 is a schematic view of the main tab installation configuration shown in FIG. 1. The utility model provides a trailer hitch attachment accessory convenient to installation, includes fixed plate 1, and locking bolt 2 is installed to the inside equidistance of fixed plate 1, and the front end fixed surface of fixed plate 1 has positioning seat 5, and the front end surface of fixed plate 1 just is located positioning seat 5 both sides and all is fixed with backplate 3, and backplate 3's shape is the semicircle arcuation, and elongated slot 8 has been seted up to positioning seat 5's inside, and there is elongated seat 10 inside positioning seat 5 through extending elongated slot 8 slidable mounting.

The screw has been seted up to the inside equidistance of extension seat 10, and the screw is the queue and distributes, and the inside of positioning seat 5 is run through there is screw rod 6, and the quantity of screw rod 6 is two, and be threaded connection between screw rod 6 and the extension seat 10, and the screw that distributes through the equidistance can make things convenient for screw rod 6 to be connected with it.

The outside both sides of screw rod 6 and the equal threaded connection in both sides that are located positioning seat 5 have the inner wall both sides of nut 7 positioning seat 5 equidistant to seted up spacing groove 9, and the both sides of extension seat 10 all are fixed with stopper 11, can carry on spacingly to extension seat 10 gliding direction through stopper 11.

The extension seat 10 forms a limit sliding connection with the positioning seat 5 through the size matching between the limit block 11 and the limit groove 9.

The front end fixed surface of extension seat 10 has main pull ring 12, and the front end fixed surface both sides of fixed plate 1 and the both sides that are located positioning seat 5 all are fixed with supplementary pull ring 4, and the user can be connected with supplementary pull ring 4 through the trailer rope of connecting the trailer rear, avoids the phenomenon of the hitch hook of being connected with main pull ring 12 because the atress is too big to take place to unhook.

The working principle of the trailer hitching device accessory convenient to install provided by the utility model is as follows;

the first step is as follows: the user mounts the fixing plate 1 at a proper position on the front end surface of the towed article by means of the locking bolt 2. Later the user is connected with main pull ring 12 through the tow hook of trailer rear installation, if the object that is dragged is great when heavier, the user can be connected with supplementary pull ring 4 through the trailer rope of connecting the trailer rear, avoids the phenomenon that the tow hook of being connected with main pull ring 12 takes place to unhook because the atress is too big.

The second step is that: when the user is being connected with main pull ring 12 at the utilization trailer hook, can be because the inconvenient trailer hook that drags of size reason of the thing piece that drags articulates with main pull ring 12, at this moment the user can be through unscrewing two outside nuts 7 of screw rod 6, later take out screw rod 6 from the inside of extension seat 10, later through the length between slide adjusting extension seat 10 and the positioning seat 5 to the trailer hook that drags of convenient trailer articulates with main pull ring 12, the position of the fixed and positioning seat 5 of extension seat 10 through two screw rods 6 and nut 7 during.

if the object that is dragged is great when heavier, the user can be connected with supplementary pull ring 4 through the trailer rope of connecting the trailer rear, avoid the present of the car puller hook of being connected with main pull ring 12 because the atress is too big takes place to unhook, the user is when utilizing the car puller hook to be connected with main pull ring 12, can probably because the inconvenient car puller hook that drags of the size reason of the object that is dragged articulates with main pull ring 12, at this moment the user can be through unscrewing two outside nuts 7 of screw rod 6, later take out screw rod 6 from the inside of extension seat 10, later through the length between slide adjusting extension seat 10 and the positioning seat 5, so that the car puller hook and the main pull ring 12 of trailer articulate, the position of fixed and positioning seat 5 of extension seat 10 through two screw rods 6 and nut 7 during.
