A double-layer travel suitcase with a detachable inner container bag is shown in figure 1 and comprises a shell 1 and the inner container bag 2, wherein a pull rod 14 and a pulley 15 are arranged on the shell 1, an inner cavity opening 17 communicated with an inner cavity is formed in the front face of the shell 1, the inner container bag 2 is arranged inside the shell 1 through the inner cavity opening 17 and detachably connected with the shell 1, the pulley 15 is arranged on the bottom face 13 of the shell 1, and the bottom face 13 of the shell 1 is of an integrated module structure, so that the pulleys 15 are all arranged on the same integrated module.

The shell 1 is made of hard metal or plastic, and is provided with a bag-shaped inner cavity, and the front surface of the shell is provided with an inner cavity opening 17 so as to place articles in the shell 1. The housing 1 may be formed by blow molding, injection molding, blister molding or by assembling a plurality of parts into an integrated structure, metal molding process and various plasticizing processes. The shell 1 is formed integrally at one time or assembled into an integral structure which can not be divided and opened and closed through splicing a plurality of frame bodies. As shown in fig. 2, the housing 1 includes a hexahedral rear end portion 12 having a hollow surface and an annular front end portion 11, and the housing 1 is formed by joining the both. No matter the shell 1 is integrally formed or spliced and assembled, the main body of the shell is of an integrated structure without division and opening and closing, and the bottom surface 13 of the shell is of an integrated integral module structure, so that the pulleys 15 arranged on the bottom surface 13 are arranged on the same integral module, when the suitcase moves, the pulleys 15 do not generate relative displacement, the integral balance and stability are ensured, the stress of the pulleys 15 is uniform, the service life is prolonged, and meanwhile, the force of extra expenditure caused by unbalanced stress can be saved. The side face of one end or two ends of the shell 1 is provided with a ring buckle 16, the braces 3 pass through the ring buckle 16 and are fixed outside the shell 1 in a surrounding mode, the braces 3 bypass the upper portion of the inner cavity opening 17, namely the middle portion outside the shell 1, the inner container bag 2 is blocked inside the shell 1, and the inner container bag 2 is prevented from falling out of the inner cavity of the shell 1.

As shown in fig. 3, the inner bag 2 is made of one of PVC, TPU and EVA, and may be made of waterproof cloth, so that it is soft and easy to deform, and is conveniently inserted into the housing 1 through the inner cavity opening 17. Structurally, the inner container bag 2 comprises a main body 21 and component parts, the main body 21 and the component parts can be connected in a hot pressing or sewing mode, and the whole inner container bag 2 can be formed through blow molding. Wherein, the inner bag 2 is formed by splicing the single components of the materials, and the components can also be formed by compounding multiple layers. The components of the inner container bag 2 are formed by laminating or compounding a TPU layer arranged at two ends and an EVA layer clamped in the middle. In addition, the front panel is provided with an opening of the liner bag 2 for placing articles, such as an annular zipper which is not connected end to end. Because the centre of inner bag 2 is the EVA intermediate layer, the EVA material can obtain great hardness through the modulation, help the type of moulding of inner bag and have certain elasticity, so when inner bag 2 puts into shell 1, the inner chamber of shell 1 is filled in to the method of accessible bending main part 21 or subassembly, after filling in, the EVA layer has great hardness, can strut the shape that restores to original design, make the outside of inner bag 2 support the limit of shell 1 inner chamber, so that inner bag 2 places in shell 1 inner chamber firmly. Preferably, the inner bag 2 is further provided with an elastic support mechanism, and after the inner bag 2 is plugged into the shell 1, the elastic support mechanism is manually adjusted to expand to abut against the inner wall of the shell 1, so that the inner bag 2 is supported.

Because of the surface material of inner bag 2 is TPU, TPU is an elastomer rubber, has good elasticity, plasticity and wearability, can fill to the inner chamber of shell 1 repeatedly, also can adapt to the various environments in the travel process, long service life. In addition, the TPU material is oil-resistant, water-resistant, mould-resistant, flame-retardant, ageing-resistant, not easy to stain, air-tight, and has outstanding bearing capacity, impact resistance and damping performance, and has a good protection effect on articles placed in the TPU material, and the stained TPU material can be directly washed by water, so that the recovery rate is high, and the TPU material is sanitary and environment-friendly.

Because the inner bag 2 can be dismantled and change, the user can change the inner bag 2 of different colours, different outward appearance patterns as required to the different use scenes of cooperation.

As shown in fig. 4, the rear panel of the liner bag 2 is provided with a latch 22, and the latch 22 includes a fixing ring 221 disposed at the center of the upper portion of the rear panel of the liner bag 2 and buckles 222 disposed at the two ends of the lower portion, which are distributed in a triangular shape. The straps 3 pass through the middle fixing ring 221 and are respectively connected with the buckles 222 at the two ends in a buckling manner. Thus, the liner bag 2 forms a backpack which can be used independently. When the inner bag 2 is plugged into the shell 1, the strap 3 can be detached from the inner bag 2, passes through the ring buckle 16 of the shell 1, surrounds the shell 1 and is connected in a head-to-tail buckling manner, and the inner bag 2 is prevented from falling out of the inner cavity of the shell 1. The number and positions of the fixing rings 221 and the inserting buckles 222 are not limited at all, and a plurality of fixing rings 221 and inserting buckles 222 can be arranged according to requirements and can be arranged at any position of the liner bag 2.

Wherein, one end of the inserting buckle 222 is a male plug, and the other end is a female plug; the two ends of the strap 3 are respectively a male plug and a female plug, so that the two ends of the strap 3 can be respectively buckled and connected with the buckles 222, meanwhile, the strap 3 can be buckled and connected end to form a ring shape when surrounding the shell, and the length of the strap 3 can be adjusted so as to be better fixed.

In the first embodiment, magic tapes are arranged outside the inner container bag 2 and in the inner cavity of the shell 1, and the inner container bag 2 is connected with the shell 1 through the magic tapes; in the second embodiment, a buckle belt is arranged in the inner cavity of the housing 1, and the inner bag 2 is connected with the housing 1 through the buckle 222 and the buckle belt in a buckling manner; in the third embodiment, the outer part of the inner container bag 2 and the inner cavity of the shell 1 are both provided with suckers, and the inner container bag 2 and the shell 1 are connected in an attracting way through the suckers; in the fourth embodiment, the outer part of the inner bag 2 is provided with a ring buckle or a hook ring, the inner wall of the shell 1 is provided with a hook buckle or a clip buckle, and the inner bag 2 is buckled and connected with the shell 1. In the above embodiments, the inner bag 2 and the housing 1 are detachably connected in order to fix the inner bag 2 in the inner cavity of the housing 1, and therefore, any simple detachable connection can be selected besides the above embodiments, such as the above mentioned snap-fit connection, adhesive connection, suction connection, clip connection, and the like, and the connection can be selected through the snap-fit connection of a button, the riveting of an external rivet, the connection of a clip, and the like.

When in use, the braces 3 of the inner bag 2 can be firstly detached, the inner bag 2 is plugged into the inner cavity of the shell 1, after the connection in the connection mode, articles are placed in the inner bag 2, then the braces pass through the ring buckle 16 to surround the shell 1, and the two ends of the braces 3 are buckled and connected end to end; the inner bag 2 can be taken out independently, the braces 3 and the lock catches 22 are connected, and the inner bag 2 is unfolded to be used as an independent backpack.
