Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe.Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all.It is based on The embodiments of the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all Other embodiments are fallen within the protection scope of the utility model.

As depicted in figs. 1 and 2, a kind of reinforced caravan tail thick stick, 3 He of whippletree 1 and left swing arm including being fixed on the tailstock Right swing arm 4, the left end of left swing arm 3 and the right end of right swing arm 4 pass through shaft 5 respectively and whippletree 1 is hinged., whippletree 1 is rectangular tube, Whippletree 1 is fixed on the crossbeam on caravan chassis by one group of symmetrical hook-plate 6.A guide part 7 is fixed on whippletree 1, Guide part 7 is located between two hook-plates 6.

As shown in Figure 3 and Figure 4, guide part 7 includes top plate 8 and bottom plate 11 and vertical end plate 12 and front end-plate 10.

As shown in Figures 1 to 6, the width of 7 section of guide part is greater than the width of 1 section of whippletree.In guide part 7, end plate 12, top plate 8 and the fitting of bottom plate 11 are fixed on the trailing flank and lower planes of whippletree 1；The front end of top plate 8 bends downward to form institute State guide surface 9；Front end-plate 10 is vertically fixed on the front end of guide surface 9 and the front end of bottom plate 11.Wherein, guide surface 9 and horizontal plane Angle be 5 ° ~ 35 °, the track that guide surface 9 and left swing arm 3 and right swing arm 4 open and close is corresponding, in order to make by functional module The 2 left swing arms 3 pushed and right swing arm 4 can easily be returned on whippletree 1 in return by the support and guidance of guide surface 9；Afterwards Between end plate 12 and top plate 8 at right angles, be equivalent to and be installed on whippletree 1, with this guarantee guide part 7 when being oriented to bearing load, Overturning will not be pressed down.

Weight bearing is undertaken during guiding due to guide part 7 and pressure is applied to the whippletree 1 at this, so should also be same When guarantee guide part 7 and whippletree 1 intensity, keep its solid and reliable.Therefore, vertical support plate is equipped in the lower section of bottom plate 11 13, the upper end of support plate 13 and bottom plate 11 are fixed, and the left and right ends of support plate 13 are fixedly connected with the hook-plate 6 respectively, As shown in Figure 1 to Figure 4 and shown in Fig. 6.The effect of support plate 13 is, suffered bearing capacity is shared to connecting with hook-plate 6 On automotive frame, to further strengthen the stability of guide part 7.Played the role of by the respective plate face of guide part 7, Neng Goujin One step reinforces whippletree 1.

The considerations of for 7 loss of weight of guide part, is equipped with lightening hole 17 in top plate 8, bottom plate 11 and support plate 13.It will lead It is triangle to the top plate 8 and bottom plate 11 in portion 7.As shown in Figures 1 to 4.

As shown in Figure 1, caravan can generally install the square opening 14 for traction, in the present invention square opening 14 additional on tail thick stick It is arranged in guide part 7, the opening of square opening 14 is then located at the middle position of front end-plate 10.

As shown in Figure 7, it is contemplated that caravan can generally carry out functions expanding at whippletree 1, such as increase by one can support The supporting plate 18 of bicycle 19.So being respectively fixed with the square opening 20 for grafting supporting plate 18 on two 6 sides of hook-plate, such as Shown in Fig. 7 and Fig. 8.

It should be noted that the square opening 20 being arranged beside hook-plate 6 and the square opening 14 being arranged on guide part 7 are standard Part.

As shown in Figure 7 to 10.It is connected between square opening 20 and hook-plate 6 by a L shape connector 15.The connection of L shape The vertical plane of part 15 is fixedly connected with whippletree 1, and the transverse plane of L shape connector 15 is fixedly connected with hook-plate 6.L shape connector The rectangular channel that can accommodate square opening 20 is formed between 15 and hook-plate 6, square opening 14 is plugged and fixed in the rectangular channel.

Since the thing carried on caravan tail thick stick is more, connected between whippletree 1 and hook-plate 6 to further strengthen Stability, so being respectively fixed with the reinforcement of one piece of triangle between the outside of two hook-plates 6 and the bottom surface of whippletree 1 Plate 16.The stiffening plate 16 is equipped with lightening hole 17, as shown in Fig. 1, Fig. 6 and Fig. 7.
