Description

Technical Field

[0001] The utility model relates to the field of vehicle transportation folding boxes, and particularly to a vehicle transportation folding box with an adjustable position of a two-layer vehicle frame. Background Art

[0002] At present, for a 4-car vehicle transportation folding box, a two-layer vehicle frame with adjustable angle and height is provided on the basis of the folding box. The two-layer vehicle frame is movably arranged on the folding box through support frames at both ends. After being lifted, the angle of the two-layer vehicle frame can be adjusted by adjusting the relative position between the two-layer vehicle frame and the support frames, so as to adapt to transporting more vehicle specifications. However, the connection between the support frame and the bottom frame is generally a fixed structure, which only provides the function of rotating the support frame. The non-detachable structure makes the position of the support frame non-adjustable, so that the two-layer vehicle frame cannot be adjusted in the length direction of the box body, and the space in the length direction cannot be fully utilized.

[0018] The present utility model discloses a vehicle transportation folding box with adjustable position of the second-layer frame. Both ends of the second-layer frame 4 are movably connected to the chassis 2 of the vehicle transportation folding box through support frames 1. At least one end of the support frame 1 is hinged with a mounting seat 3. Both the support frame 1 and the mounting seat 3 are provided with pin holes 34. By passing a pin through the support frame 1 and the mounting seat 3, the support frame 1 can be relatively fixed. The mounting seat 3 is arranged on the chassis 2, and the support frame 1 can be adjusted in position along the length direction of the chassis 2. The present utility model aims to provide a connection structure between the support frame 1 with adjustable position and the chassis 2, and does not limit the rest of the vehicle transportation folding box. For example, the connection structure between the support frame 1 and the second-layer frame 4, the frame structure of the second-layer frame 4, etc. can all adopt the prior art.

[0019] The following are two embodiments provided in the present utility model.

[0020] Embodiment 1:

[0021] Refer to Figure 1 and Figure 2, in this embodiment, taking the support frame 1 at the lower end of the two-layer vehicle frame 4 as an example, the adjustable position structure between the support frame 1 and the chassis 2 will be described. What is adjusted in this embodiment is the position of the support frame 1 relative to the mounting seat 3.

[0022] The mounting seat 3 corresponding to the support frame 1 includes a hinge seat 31 and a fixing plate 32. The hinge seat 31 is perpendicular to the fixing plate 32 and is located in the middle of the fixing plate 32. The fixing plate 32 is welded to the chassis 2 or integrally formed with the chassis 2. Three groups of hinge holes 33 and pin holes 34 are arranged on the hinge seat 31 along the length direction of the chassis 2. The intervals between each group are equidistant, and the hinge holes 33 in the same group are vertically below the pin holes 34.

[0023] When the support frame 1 is connected to different groups of hinge holes 33 through a hinge shaft, such as Figure 1 in which the middle support seat is connected to the second group of hinge holes 33 and pin holes 34 from left to right of the hinge seat 31, Figure 2 in which the middle support seat is connected to the first group of hinge holes 33 and pin holes 34 from left to right of the hinge seat 31, the distance between this support frame 1 and the support frame at the other end of the two-layer vehicle frame 4 can be changed. Thus, according to the shipping requirements, the position of the two-layer vehicle frame 4 along the length direction of the chassis 2 can be adjusted to make full use of the space in the length direction of the vehicle transportation folding box. To relatively fix the support frame 1 to make it vertical, a pin also needs to be inserted into the pin hole 34 of the same group to lock the support frame 1.

[0024] Embodiment Two:

[0025] Refer to Figure 3 , in this embodiment, also taking the support frame 1 at the lower end of the two-layer vehicle frame 4 as an example, the adjustable position structure between the support frame 1 and the chassis 2 will be described. What is adjusted in this embodiment is the position of the mounting seat 3 relative to the chassis 2.

[0026] The mounting seat 3 includes a hinge seat 31 and a fixing plate 32. The hinge seat 31 and the fixing plate 32 are integrally formed. The hinge seat 31 is perpendicular to the fixing plate 32 and is located in the middle of the fixing plate 32. The support frame 1 is hinged to the hinge seat 31, and only one group of hinge holes 33 and pin holes 34 are arranged on the hinge seat 31. The fixing plate 32 is parallel to the chassis 2 and directly contacts the chassis 2. Combining with Figures 3 to 6 , a number of fixing holes 35 are opened on the fixing plate 32, evenly distributed on both sides of the mounting seat 3. Two groups of adjustment holes 21 are opened on the chassis 2 at intervals along its length direction. The specific quantity and the involved range are set according to the actually adjustable distance in the length direction of the vehicle transportation folding box.

[0027] After the fixing holes 35 are aligned with different adjustment holes 21, the fixing plate 32 and the chassis 2 can be tightened sequentially from top to bottom by bolts. The adjustment holes 21 at different positions in the length direction of the chassis 2 enable the position of the mounting seat 3 relative to the chassis 2 to be adjustable, that is, the position of the support frame 1 relative to the chassis 2 to be adjustable. Generally, both the fixing holes 35 and the adjustment holes 21 are round holes. Refer to Figure 4 , and the fixing of the bolts will be more stable. To facilitate the adjustment of the position of the fixing plate 32 or to adapt to more adjustment situations, either the fixing hole 35 or the adjustment hole 21 can be adjusted to an oblong hole. Specifically: Refer to Figure 5 , the fixing hole 35 is an oblong hole and the adjustment hole 21 is a round hole; Refer to Figure 6 , the fixing hole 35 is a round hole and the adjustment hole 21 is an oblong hole. The length and number of the oblong holes can be set according to the required moving distance, and the required number of bolts is based on the number of round holes participating in the fixing.

[0028] In some cases, the structures of the first embodiment and the second embodiment can also be combined for use. The specific implementation needs to consider the specific structure of the vehicle-carrying folding box. In the prior art, there are generally two connection structures for the support frame at the higher end of the second-layer frame 4 in the vehicle-carrying folding box: one is only hinged to the chassis 2, and the other is fixable perpendicular to the chassis 2. For the former connection structure, only the pin hole 34 structure of the mounting seat 3 in the above different embodiments needs to be hidden to achieve the position adjustment of the end support frame; for the latter connection structure, the two provided embodiments can be directly adopted.

[0029] In summary, the present utility model adopts two different connection structures, enabling the support frame 1 provided on the chassis 2 to be position-adjustable along the length direction of the chassis 2, so that the second-layer frame 4 can make full use of the space in the length direction of the box body. Combined with the height and angle adjustment technologies in the prior art, the second-layer frame 4 can transport more vehicle specifications.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
