Description

Combined fixing structure for inner lining of case

Technical Field

The utility model relates to the field of bags and suitcases, in particular to a combined fixing structure for a bag lining.

Background

In present case and bag trade, the case shell inside of case and bag (especially draw-bar box) all is equipped with the inside lining generally, and at present, traditional inside lining fixed mode generally has following several:

the first method is a glue adhesion fixing mode: the periphery of the lining which is sewn is fixed at the opening of the box shell by a glue adhesion fixing mode, and the mode principle is simple and has wide application. However, in practical applications, the following problems exist with this process: (1) the production operation is not convenient and low in efficiency. The operation of gluing with glue in the production process is complex and long, and the subsequent cleaning of redundant glue is needed; (2) the reliability is insufficient, the inner liner is fixed by a glue adhesion connection, the fixing strength between the inner liner and the box body is low, when the load of a storage structure in the inner liner is large, the position of the inner liner adhesion connection is easy to fall off, and the integral fixing strength is not ideal; (3) the weather resistance is poor, the performance of the glue is greatly influenced by the temperature and the service life, and the service life is not ideal.

The second method is a sewing fixing mode: the four peripheral edges of the sewn lining are sewn on the opening edge of the box shell by using needle lines, the principle of the mode is simple, but the following defects exist in practical application: (1) the process limitation is large, the process of fixing the lining by sewing can only be applied to the case made of soft materials such as textile materials or plastics, and the case is also bound to be a zipper opening and closing structure, and a metal hard frame (such as an aluminum frame and a magnesium frame) can not be combined with a sea-closing lock structure, so the process limitation of needle and thread sewing fixing is large; (2) the production operation is not convenient, the whole box shell needs to be lifted for long-time operation by using the process of fixing the lining by sewing, when the size of the box shell is larger, the production operation is not convenient enough, workers are easy to fatigue, and the production efficiency is influenced; (3) the maintenance and the replacement can not be carried out, which is shown in the following steps: because the sewing process belongs to an irreversible assembly mode, the lining cannot be repaired or replaced. (4) Low rigidity and poor strength, as shown in: because of less support of the hard frame, the liner is easy to deform under full load or overload, and has low rigidity and poor strength.

The third method is a metal wire binding and fixing mode: the sewn integral lining is fixed on a hard frame (such as an aluminum frame and a magnesium frame) at the opening of the box shell by binding the four peripheral edges of the integral lining with metal wires and combining a glue adhesion fixing mode, but in practical application, the process has the following defects: (1) the production operation is inconvenient and low in efficiency, more fixing points are needed in the mode of binding and fixing by using the metal wires, so that more steps needing binding are needed, the whole box shell needs to be lifted for a longer time of operation, when the size of the box shell is larger, the production operation is inconvenient and inconvenient, workers are easy to fatigue, and the production efficiency is influenced; (2) the reliability is insufficient, even if the fixing points are dense, a certain distance always exists between the adjacent fixing points in the metal wire binding and fixing mode, the distance is fixed only by means of glue adhesion, the fixing strength is low, and the integral fixing strength is not ideal; (3) the process of binding the metal wire is also an irreversible assembly mode, so that when the lining needs to be maintained or replaced, the fixed point of binding needs to be destroyed, and the lining and the box shell can be destroyed at the same time, so that the lining is inconvenient to maintain or replace.

The fourth method is a rivet fixing method: the four peripheral edges of the sewn integral lining are fixed on a metal hard frame (such as an aluminum frame and a magnesium frame) at the opening of the box shell in a fixing mode of riveting by rivets and bonding by glue, but in practical application, the process has the following problems: (1) the production operation is not convenient and low in efficiency. The mode of using the rivet for fixing has to have more fixed points, so that more riveting steps are needed, the whole box shell needs to be lifted for longer time of operation, when the size of the box shell is larger, the production operation is not convenient enough, workers are easy to fatigue, and the production efficiency is influenced; (2) the reliability is insufficient, even if the fixing points are dense, a certain distance always exists between the adjacent fixing points in the rivet fixing mode, the distance can be fixed only by glue adhesion, the fixing strength is low, and the integral fixing strength is not ideal; (3) the lining is inconvenient to maintain or replace because the rivet riveting and fixing process also belongs to an irreversible assembly mode, and the riveted fixing point needs to be damaged when the lining needs to be maintained or replaced, so that the lining and the box shell can be damaged at the same time.

In order to solve the above problems, the applicant has previously developed a new liner fixing structure, in which a locking groove is designed on a hard frame, and a locking strip is added to cooperate with a clamping strip for fixing the peripheral edge of the liner, so as to fix the peripheral edge of the liner on the hard frame. In the structure mode, the locking strip is used as a key part, and after the lining and the clamping strip are installed, the lining and the clamping strip are plugged into the slotted opening of the hard frame, but because a continuous whole strip of adhesive tape is adopted, certain difficulty exists in the lining assembling process, the assembling efficiency is low, and the labor cost is high; simultaneously, the locking strip after the installation is located the inside lining outside, influences the aesthetic property of case and bag easily.
