Description

Technical Field

[0001] This utility model belongs to the field of luggage thermoforming technology, specifically relating to a new type of lining and luggage. Background Technology

[0002] The existing production process for hard-shell suitcases is as follows: plastic granules are melted at high temperature and made into sheets. The sheets are placed on a mold that forms half of the suitcase shell. High-pressure air is blown onto the mold to adhere the sheets. After cooling, the suitcase shell is formed.

[0003] Trim off excess edge material from half of the box shell and drill pre-drilled holes in it; bolts are passed through the bottom of the box shell and connected to the rollers; pull rods are passed through the box shell and secured with bolts; the lining is cut to the required size, and the lining and zipper are sewn together with a sewing machine, and the edges are bound.

[0004] The lining inside the box covers the top of the rollers, bolts, and pull rods, which not only improves the appearance but also protects the clothes from being scratched. However, the lining is usually connected to the box shell by sewing, which will damage the integrity of the box shell; some use glue to stick the lining, but the lining is a layer of fabric, and the adhesive has limited strength and is not strong enough. At the same time, as a layer of fabric, the lining cannot be completely and completely fixed inside the box shell.

[0005] Currently, there are no suitcases on the market that do not use lining, so a new structure needs to be proposed to replace the lining. Summary of the Invention

[0006] In view of the shortcomings of the above-mentioned background technology, the purpose of this utility model is to provide a new type of lining that can replace the lining fabric, can be fully attached to the inner surface of the box shell, is flatter, and is glued with good firmness.

[0007] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: A novel interior lining and suitcase, the interior lining including a first plate, the first plate being attached and fixed to the inner surface of the front wall of the suitcase shell, or the first plate being attached and fixed to the inner surface of the rear wall of the suitcase shell and the outer surface of the pull rod; The four edges of the first plate extend to form the first side plates, the four first side plates are connected and closed, and the four first side plates are respectively attached and fixed to the inner surface of the side wall of the box shell; the interior is completely covered inside the box shell.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: two first grooves are recessed on the outer surface of the first plate, and the pull rod is placed in the first groove.

[0009] Based on the above scheme and as a preferred option, the inner lining is made of EVA or felt material through hot pressing.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the inner outer surface is covered with a waterproof layer.

[0011] A suitcase with a novel lining, including the lining; The suitcase consists of a front shell and a rear shell; the bottom of the front shell is equipped with wheels, the bottom of the rear shell is equipped with wheels, and a pull rod is installed inside the rear shell; The inner outer surface is coated with glue and adhered to the front or rear box shell.

[0012] Based on the above scheme and as a preferred option, the inner cross-sectional thickness is 2 to 10 millimeters.

[0013] The outstanding and beneficial technical effects of this utility model compared to the prior art are: This utility model discloses a novel lining and suitcase. Compared with the prior art, it uses a lining instead of fabric. The first panel of the lining is bonded to the inner surface of the suitcase shell and the outer surface of the pull rod. The lining is glued on instead of sewn. This will not damage the suitcase shell and avoids water leakage. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments; This embodiment provides a novel lining, the lining 01 including a first plate 010, the first plate 010 being attached and fixed to the inner surface of the front wall of the housing 02, or the first plate 010 being attached and fixed to the inner surface of the rear wall of the housing 02 and the outer surface of the pull rod 03. The first plate 010 of the inner 01 is shaped according to the different positions of the box shell 02 and different sizes / specifications, so that it can fit completely inside the box shell 02; The four periphery edges of the first plate 010 extend to form first side plates 011. The four first side plates 011 are connected and closed, and the four first side plates 011 are respectively attached and fixed to the inner surface of the side wall of the box shell 02; the lining 01 is completely filled inside the box shell 02. The four first side plates 011 are attached to the side wall of the box shell 02.

[0021] As mentioned above, the inner lining 01, which adopts an integrated structure, is used instead of the inner fabric; the inner lining 01 is made into the shape of a "shell" so that it can fit and be fixed inside the box shell 02 without shifting. Furthermore, two first grooves 0100 are recessed on the outer surface of the first plate 010, and the pull rod 03 is placed in the first grooves 0100.

[0022] As described above, the first groove 0100 is used to place the pull rod 03, wrapping around the pull rod 03, making the inner 01 flatter; Furthermore, the inner lining 01 is made of EVA or felt material through hot pressing.

[0023] As mentioned above, the one-piece thermoformed lining 01 is being used for the first time in a suitcase; production is fast and reduces production processes.

[0024] Furthermore, the outer surface of the inner 01 is covered with a waterproof layer.

[0025] As described above, the waterproof layer is made of a waterproof membrane or waterproof coating, and the PE waterproof membrane and the inner lining 01 are bonded together by heat pressing. This gives it a waterproof effect, and prevents liquid from seeping into the casing 02, making it easy to clean.

[0026] In another embodiment, the outer surface of the inner lining 01 is designed with recesses to match the shape of the pull rod 03 for fixing items, making it more practical.

[0027] A suitcase with a novel lining 01, comprising the lining 01; The suitcase includes a front box 02 and a rear box 02; the bottom of the front box 02 is equipped with wheels, the bottom of the rear box 02 is equipped with wheels, and the interior of the rear box 02 is equipped with a pull rod 03. The outer surface of the inner lining 01 is coated with adhesive and attached to the front or rear box shell 02.

[0028] As described above, the inner lining 01 is produced according to the cash box shell 02 and the rear box shell 02 of the suitcase. The inner lining 01 covers the rollers and the pull rod 03, resulting in a smooth inner lining 01. The inner lining 01 is glued and fixed around the edge and on the bottom, replacing the need for sewing, thus avoiding the problem of water leakage caused by sewing damaging the box shell 02.

[0029] Furthermore, the cross-sectional thickness of the inner 01 is 2 to 10 millimeters, which can meet different elasticity requirements.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, or the orientation or positional relationship commonly understood by those skilled in the art.
