Summary of the invention
The problem to be solved in the present invention is that existing tow ball rapid wear changes, matching is little, and car puller hook is unadjustable, is unfavorable for the use of compact car.Below do corresponding modify
For solving the problems of the technologies described above, the technical solution used in the present invention is: provide a kind of Trailer equipment, and described Trailer equipment comprises fixed arm, connecting arm, hold-down arm, regulating arm, extension arm and tow ball.
Described connecting arm and described fixed arm removably connect.
Described hold-down arm comprises transverse arm and bending arm, and described transverse arm is fixedly connected with bending arm, and its axis is mutually vertical; Described transverse arm is fixedly connected with described connecting arm, the axis of transverse arm and the axis perpendicular of connecting arm.
Described regulating arm and described bending arm removably connect, and the axis direction of regulating arm and the direction of bending arm coincide.
One end of described extension arm is connected with described regulating arm fixed vertical, and the other end is provided with tow ball, and described tow ball is flexibly connected with described extension arm.
Further, described Trailer equipment also comprises fastener, the through hole matched with described fastener that the bilateral symmetry of described bending arm has some vertical arrangements, the adjustment through hole matched with described fastener described regulating arm having some vertical arrangements, described bending arm is hollow structure, and described regulating arm can slide up and down in described bending arm.
Preferably, described fastener is bolt or bearing pin.
Further, one end that described fixed arm is connected with connecting arm has internal thread hole, and one end that described connecting arm is connected with described fixed arm has the outside thread matched with described internal thread hole, and described fixed arm and connecting arm are spirally connected.
Preferably, described Trailer equipment also comprises reinforced plate, is arranged on the region that described regulating arm is connected with extension arm, and described reinforced plate is all fixedly connected with extension arm with described regulating arm.
Preferably, described tow ball outside is provided with protecting sleeve
The advantage that the present invention has and good effect are:
(1) the novel Trailer equipment provided of this use, applicability is strong, Height Adjustable, also can use even if vehicle is little;
(2) fast easy to install, only need connecting arm and fixed arm to be threaded connection and can to use;
(3) take up space less, can carry with car easily when not using; Without the need to being chronically exposed to outside car body by whole Trailer equipment, extend the service life of tow ball;
(4) structure is simple, becomes to produce cost low.

Detailed description of the invention
For a better understanding of the present invention, below in conjunction with detailed description of the invention and accompanying drawing, the present invention is conducted further description.
As shown in Figure 1, a kind of Trailer equipment, comprises fixed arm 1, connecting arm 2, hold-down arm 3, regulating arm 4, extension arm 5, tow ball 6, fastener 7 and reinforced plate 8.
Fixed arm 1 is fixedly connected with car, and in present embodiment, fixed arm 1 is welded on the lower end of the bumper/spoiler of car, and the axes normal of fixed arm is in horizontal surface.
Fixed arm 1 is connected with connecting arm 2, and one end that fixed arm 1 is connected with connecting arm 2 has internal thread hole, and one end that connecting arm 2 is connected with fixed arm 1 has the outside thread 21 matched with internal thread hole, and fixed arm 1 and connecting arm 2 are spirally connected.
Fixed arm 2 starts to downward-extension from connecting arm 1, ends at hold-down arm 3, and hold-down arm 3 and fixed arm 2 weld.
Hold-down arm 3 comprises transverse arm 31 and bending arm 32, and transverse arm 31 is fixedly connected with bending arm 32, one-body molded.Transverse arm 31 welds with connecting arm 2, and transverse arm 31 starts along horizontal-extending from connecting arm 2, ends at bending arm 32.Bending arm 32 is hollow structure, starts upwards to extend from transverse arm 31, and the bilateral symmetry of bending arm 32 has some through holes 321 matched with fastener 7.
Regulating arm 4 is connected with bending arm 32, regulating arm 4 has some adjustment through holes 41 matched with fastener 7, regulating arm 4 is inserted in the hollow structure of bending arm 32, by fastener 7 simultaneously through through hole 321 and adjustment through hole 41, regulating arm 4 and bending arm 32 can be fixed.By the relative position of fastener 7 on regulating arm 4 and bending arm 32, the height of adjustable whole Trailer equipment.
