Description

Foldable suitcase

This creation is the use of suitcase technology, specifically a suitcase that can be folded and does not take up space.

The traditional suitcase basically adopts a fixed box structure. The size and volume of the suitcase are fixed. The rollers of the suitcase are also fixed connection structure; when the use is over, the large box storage is occupied. The large space is a space storage problem for most families with a narrow living environment.

In order to meet the needs of use and storage space savings, there are a variety of suitcases on the market that can adjust the height of the box around the box, but for the four-wheel suitcase, the height adjustment range of the box is limited, and the fixed connection is also fixed. The scroll wheel under the suitcase will occupy the storage space, so the existing adjustable cabinet space has a limited adjustment range and basically does not achieve the desired effect.

The present invention mainly provides a function of a structural suitcase with a foldable bottom and a detachable roller at the bottom of the suitcase to overcome the problems in the prior art.

The creation is a foldable suitcase with novel concept and innovative structure. The bottom of the box adopts front and rear foldable structure, and the roller adopts a detachable structure, which can adjust the volume of the box to a minimum state during idle storage, which can fully save Storage space, very practical in use Significant space saving effects.

Figure 1 is a schematic diagram of the new structure of the creation

Figure 2 is a schematic view showing the structure of the bottom of the box in the creation state

FIG. 3 is a schematic structural view of the folding process of the bottom of the box according to the present invention.

As shown in the figure, it is a foldable suitcase, which comprises a box body 2 and a telescopic pull rod 1 coupled thereto. The box bottom 3 of the box body 2 adopts a front and rear foldable structure, and a set of rod jacks 12 are arranged on the rear side of the box bottom 3. The utility model is used for inserting the telescopic pull rod 1 , and the outer side of the bottom of the bottom 3 is connected with the detachable roller 7 through the box wheel connecting member 9 , for example, the roller 7 is engaged with the box wheel connecting member 9 through the disassembling button 8; when the suitcase needs to be stored Press the disassembly button 8 to remove the roller 7 from the box wheel connector 9, and then center the box bottom 3 back and forth, and put the removed roller 7 into the fulfillment box, at which time the suitcase reaches the minimum state, and the storage box is stored. It is very space-saving, and when it is needed, the bottom 3 of the box is opened and the roller 7 is snapped onto the box wheel connecting member 9 through the disassembly button 8, and the operation is convenient.

The center front and rear foldable structure adopted by the bottom 3 of the above embodiment can be realized by providing a folding groove 5 in the middle of the box bottom 3 so that the front and rear portions of the box bottom 3 can be folded in the middle along the folding groove 5, in order to prevent the front and rear of the box bottom 3 The portion is excessively folded, and the folding limit block 14 is disposed in the left and right of the folding groove 5. The folding limit block 14 may have a triangular cross section, a trapezoidal shape or the like such that the top width thereof is smaller than the bottom width; the left and right sides of the bottom 3 of the box are respectively supported by the support. The rod connecting member 10 is connected with the rear strut 4 and the front strut 6. The rear strut 4, the front strut 6 and the strut connecting member 10 are respectively rotated and matched, and the rear strut 4 and the front strut 6 on the same side are respectively The inner end crosses the movable joint and is provided with a snap-fit fixing structure. The inner end of the front strut 6 is provided with a limiting plate 13 and a limiting hole 16 disposed on the mating surface of the rear strut 4, and the through hole 15 is disposed on the limiting plate 13 For fixing the connecting brace; the inner end limiting plate 13 of the rear strut 4 is top-contacting, and the limiting post 11 is integrally formed correspondingly with the mating surface of the front strut 6; when the suitcase is used, the bottom 3 of the box is opened, such as As shown in FIG. 2, the limiting post 11 on the rear strut 4 snaps into the front strut on the same side. In the limiting hole 16 on the 6th, the upper end of the inner end of the rear strut 4 is in contact with the limiting plate 13 provided at the top of the inner end of the front strut 6, and the front strut 6 and the rear The struts 4 are fixed on the same straight line, and the bottom 3 of the box is fixed in an open state; when the suitcase is required to be stored, in order to save storage space, the bottom 3 of the box can be folded up, and only the puller is fixed at the limit plate at this time. The brace in the through hole 15 on the 13 will rotate the front strut 6 counterclockwise, the rear strut 4 rotates clockwise and the upper end of the inner end is always in contact with the limit plate 13 first, firstly the limit column 11 Fold out from the limiting hole 16, and then the front strut 6 and the rear strut 4 change from being in a straight line to the inverted V-shaped structure shown in FIG. 3, and the angle between the two is getting smaller and smaller until the bottom of the box is closed. 3Folding back and forth with the folding groove 5 as the center; only need to push the front strut 6 and the rear strut 4 toward the bottom of the box when opening, the front strut 6 rotates clockwise, and the rear strut 4 counterclockwise Rotating and the upper part of the inner end is always in contact with the top plate 13 , and the angle between the front strut 6 and the rear strut 4 is gradually increased until the front strut 6 and the rear strut 4 are in the same straight line and the limit post 11 slides into the limiting hole 16, the limiting column 11 is engaged with the limiting hole 16, and the upper end of the inner end of the rear strut 4 is in contact with the limiting plate 13 The front strut 6 and the rear strut 4 are positioned to open and fix the bottom 3 of the box in the open state, that is, the state shown in FIG. 2; the folding structure of the box bottom 3 makes the whole folding and opening operation simple and the main increase of the suitcase The components are the front strut 6 and the rear strut 4, which have no obvious influence on the production cost of the suitcase and the weight of the suitcase, but the effect of saving the storage space is very significant.
