Description

A retractable luggage trailer

technical field

The utility model belongs to the technical field of luggage hauling tools, in particular to a retractable luggage trailer.

Background technique

At present, most luggage trailers on the market have a fixed base frame, and when hauling, the luggage is directly placed on the base frame. However, if you encounter larger or longer luggage, ordinary luggage trailers cannot be hauled. The most direct way to solve this problem is to temporarily increase the base frame, but this method is costly and at the same time very Trouble.

Utility model content

The purpose of this utility model is to propose a retractable luggage trailer capable of hauling large luggage in view of the above-mentioned deficiencies.

The technical scheme that the utility model adopts is:

A retractable luggage trailer, comprising a base frame, a telescopic base frame and a pull rod, one side of the base frame is interfitted and slidably connected with the telescopic base frame, and the other side of the base frame is fixed with an angle connector, and the angle The connecting piece and the pull rod are hinged, base wheels are installed at the rear of the base frame, and telescopic wheels are installed at the tail of the telescopic base frame.

Further, the main wheel bracket is fixed at the bottom of the pull rod, and the main wheel is installed on the main wheel bracket.

Preferably, the main wheel bracket is a V-shaped main wheel bracket.

Further, there are positioning holes on both sides of the base frame.

Preferably, the number of the positioning hole is at least one.

Preferably, the other side of the base frame is fixed to the angled connector by welding.

Preferably, the pull rod is in a telescopic form.

Further, a moving cross bar is installed on the telescopic base frame.

Preferably, the number of the moving cross bar is at least one.

The beneficial effects of the utility model are:

The device has a simple structure and low production cost; the device is composed of a base frame and a telescopic base frame. The problem of large luggage that is difficult to haul.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described further.

Referring to FIGS. 1 to 4 , this embodiment provides a retractable luggage trailer, including a base frame 6 , a telescopic base frame 7 and a pull rod 2 . One side of the base frame 6 is slidably connected with the telescopic base frame 7 . The other side of the base frame 6 is welded to fix the angled connector 5 . Angle connector 5 is hinged with pull rod 2, and pull rod 2 is telescopic form. The base frame 6 rear portion is equipped with a base wheel 9, and the afterbody of the telescopic base frame 7 is equipped with a telescopic wheel 8. The V-shaped main wheel support 3 is fixed at the bottom of the pull rod 2, and the main wheel 4 is installed on the V-shaped main wheel support 3. Three positioning holes 10 are respectively opened on both sides of the base frame 6 . Four mobile cross bars 1 are installed on the telescopic base frame 7 .

When the luggage is not very large, with reference to FIG. 1 , the luggage can be directly placed on the telescopic base frame 7 . When the luggage is very large, with reference to Figure 2, it is only necessary to pull out the telescopic base frame 7 to the position of the corresponding positioning hole, and at the same time pull out the moving cross bar 1 on the telescopic base frame 7 evenly, so that the telescopic base frame 7 is evenly supported. It is ready to use and puts large luggage. When not working, with reference to Fig. 3, two parts of the base frame 6 and the telescopic base frame 7 can be contracted.

The device is simple in structure and low in production cost; the device is composed of a base frame 6 and a telescopic base frame 7. When encountering large luggage, the telescopic base frame 7 only needs to be pulled apart to put the large luggage on it , which solves the problem that large luggage is difficult to haul.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modifications or equivalent replacements of the technical solutions of the new utility model without departing from the spirit and scope of the technical solutions of the utility model shall be covered by the claims of the utility model.
