A double-layer suitcase with a removable inner bladder, as shown in Figure 1, includes an outer casing 1 and an inner bladder 2, the outer casing 1 is provided with a pull rod 14 and a pulley 15, and the front of the outer casing 1 is provided with an inner cavity opening 17 and The inner cavity is connected, the inner bladder 2 is arranged inside the outer casing 1 through the inner cavity opening 17 and is detachably connected with the outer casing 1, the pulley 15 is arranged on the bottom surface 13 of the outer casing 1, and the bottom surface 13 of the outer casing 1 is integrated into the overall module structure, so that the pulley 15 are all set on the same overall module.

The outer shell 1 is made of hard metal or plastic, and has a bag-shaped inner cavity, and an inner cavity opening 17 is opened on the front surface of the outer shell 1 so that articles can be placed inside the outer shell 1 . The shell 1 can be formed by blow molding, injection molding, suction molding, or by assembling multiple components to form an integrated structure, and both metal molding processes and various plasticizing processes can be used. The shell 1 is either integrally formed at one time or assembled by splicing a plurality of frames into an integral structure that cannot be separated and closed. As shown in FIG. 2 , the casing 1 includes a rear end portion 12 of a hollow hexahedron and an annular front end portion 11 , and the casing 1 is formed by splicing the two. Regardless of whether the housing 1 is integrally formed or assembled by splicing, its main body is an integral, non-divided, non-opening and closing structure, and its bottom surface 13 is an integral integral module structure to ensure that the pulley 15 disposed on the bottom surface 13 is disposed in the On the same integral module, when the suitcase moves, the pulleys 15 do not produce relative displacement, which ensures the overall balance and stability. A loop buckle 16 is provided on the side of one or both ends of the shell 1, the strap 3 passes through the loop buckle 16 and is fixed on the outside of the shell 1, and the strap 3 bypasses the upper part of the cavity opening 17, that is, the outer middle part of the shell 1. The bag 2 is blocked inside the outer casing 1 to prevent the inner bladder bag 2 from falling out of the inner cavity of the outer casing 1 .

As shown in FIG. 3 , the inner bladder 2 is made of one of PVC, TPU and EVA, and it can also be a waterproof fabric, which is soft and easy to deform as a whole, and is convenient to be inserted into the shell 1 from the cavity opening 17 . Structurally, the inner bladder 2 includes a main body 21 and each component part, the main body 21 and each component part can be connected by heat pressing or sewing, and the whole inner bladder 2 can also be formed by blow molding. Among them, the above-mentioned several materials can be used as single components to form the inner bladder 2 , and can also be used as multi-layer composite components. The components of the inner bladder 2 include a TPU layer provided at both ends and an EVA layer sandwiched in the middle, which are laminated or compounded. In addition, an opening of the inner bladder 2 is provided at the front panel for placing items, such as opening a loop zipper that is not connected end to end. Since the middle of the inner bladder 2 is an EVA interlayer, the EVA material can be modulated to obtain greater hardness, which is helpful for the shaping of the inner bladder and has a certain elasticity. By bending the main body 21 or the components and inserting it into the inner cavity of the outer shell 1, after inserting, the EVA layer has greater hardness, and will be stretched and restored to the original shape, so that the outer part of the inner bladder 2 can resist The side of the inner cavity of the outer shell 1 is closed, so that the inner bladder 2 is placed in the inner cavity of the outer shell 1 stably. Preferably, the inner bladder 2 is also provided with an elastic support mechanism. After the inner bladder 2 is inserted into the outer casing 1, the elastic supporting mechanism is manually adjusted so that the elastic supporting mechanism is deployed against the inner wall of the outer casing 1 to support the inner bladder. 2 role.

Because the surface material of the inner bladder 2 is TPU, TPU is an elastomer rubber with good elasticity, plasticity and wear resistance, which can be repeatedly stuffed into the inner cavity of the outer shell 1, and can also adapt to the travel process. Various environments, long service life. In addition, TPU material is oil-resistant, water-resistant, mold-resistant, flame-retardant, aging-resistant, and not easy to get dirty. It has a very good protective effect. It can be washed directly with water if it is dirty. It has a high recovery rate and is hygienic and environmentally friendly.

Since the inner bladder 2 is detachable and replaceable, the user can replace the inner bladder 2 with different colors and different appearance patterns according to needs, so as to match different usage scenarios.

As shown in FIG. 4 , the rear panel of the inner bladder 2 is provided with a lock 22. The lock 22 includes a fixing ring 221 arranged at the center of the upper part of the rear panel of the inner bladder 2 and a latch 222 arranged at both ends of the lower part. Triangular distribution. The strap 3 passes through the middle fixing ring 221, and is connected with the buckles 222 at both ends respectively. In this way, the inner bladder 2 forms a backpack that can be used alone. When the inner bladder 2 is inserted into the outer shell 1, the strap 3 can be detached from the inner bladder 2, pass through the buckle 16 of the outer shell 1, surround the outer shell 1 and be connected end-to-end to block the inner bladder 2 from the outer shell 1. out of the lumen. The numbers and positions of the fixing rings 221 and the buckles 222 are not limited in any way, and several fixing rings 221 and buckles 222 can be provided according to requirements, and can be arranged at any position of the inner bladder 2 .

Among them, one end of the 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 connected with the buckle 222. At the same time, the strap 3 When surrounding the shell, it can be connected end-to-end to form a loop, and the length of the strap 3 can also be adjusted for better fixation.

In the first embodiment, Velcro is arranged on the outside of the inner bladder 2 and in the inner cavity of the outer shell 1, and the inner bladder 2 and the outer shell 1 are connected by the Velcro; in the second embodiment, the inner cavity of the outer shell 1 is set There is a buckle, and the inner bladder 2 is connected with the outer shell 1 through the buckle 222 and the buckle; It is connected with the outer shell 1 through suction cups; in the fourth embodiment, the outer part of the inner bladder 2 is provided with a loop or a hook, the inner wall of the outer shell 1 is provided with a hook or a clip, and the inner bladder 2 and the outer shell 1 are provided with a hook or a clip. Snap connection. In the above embodiment, the connection mode of the inner bladder 2 and the outer shell 1 is detachable connection, in order to make the inner bladder 2 fixed in the inner cavity of the outer shell 1, therefore, in addition to the above embodiment, any simple The detachable connection, such as the above-mentioned buckle connection, paste connection, suction connection, clip connection, etc., can also be selected by button buckle connection, external rivet riveting, using clip connection and so on.

When in use, first remove the back strap 3 of the inner bladder 2, insert the inner bladder 2 into the inner cavity of the outer shell 1, and after connecting through the above connection method, place the item into the inner bladder 2, and then put the strap through the inner bladder 2. The loop buckle 16 surrounds the outer shell 1, so that the two ends of the strap 3 are connected end-to-end; the inner bladder 2 can also be taken out separately, and the strap 3 and the buckle 22 can be connected, and the inner bladder 2 can be opened and used as a separate backpack .

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included in the present invention. within the scope of protection of the utility model.
