Description

Hard case suitcase

The invention specifically refers to a hard-shell suitcase case which is fast in production speed, low in defect rate and heat-resistant and cold-shrinkable.

According to the conventional hard-shell suitcase, the first outer casing and the second outer casing are respectively formed by using ABS as raw materials, and the first outer casing opening rives the first aluminum frame, and the second outer casing opening is riveted. a second aluminum frame for coupling the first and second aluminum frames through the hinge for achieving the functions of the first and second outer casings for opening and closing the storage. The first and second aluminum frames have better structure, which is sufficient It can withstand the constant opening and closing force of the first and second shells, and can provide standard accessories such as handles, hinges and locks.

In general, the specific structure of the first and second aluminum frames is as described in the prior art of the publication No. M448181 of the prior art, and has holes and slots for lifting the handle and the hinge and the lock assembly, and the holes and slots are The utility model is disposed in a groove, and the groove can cover a decorative strip correspondingly, so that the decorative strip can cover the holes and the groove, so as to maintain the overall appearance of the suitcase, so that the decorative strip does not fall off casually, The left and right sides of the control strip can be fastened to the two side walls of the groove, so the shape of the groove must be T-shaped or dovetail-shaped, so that the first and second aluminum frames must be processed by aluminum extrusion. The groove is then cut off to the required length, and then the hole for lifting the handle and the hinge is punched out at the groove position, and the groove for assembling the lock is punched out, and finally the bending is made, but This method has at least the following disadvantages:

1. The production speed is too slow; from the above description, the first and second aluminum frames must be subjected to aluminum extrusion processing → cutting → punching holes, grooves → bending procedures. The process cannot be connected by the production line, and it must be repeatedly cut off, punched, and bent. In particular, the bending needs to be adjusted repeatedly by the operator, which not only accumulates working hours due to the increase in the number of movements, but also causes The work efficiency of the completion of the first and second aluminum frames cannot be improved, and it is even harder to mention the increase in economic efficiency. This is where the current processing technology cannot break through.

2. The non-performing rate is high; the holes and slots that are punched by the first and second aluminum frames often have a loss of accuracy after being bent, which may cause troubles in subsequent assembly, and the need to completely scrap. Under the condition that the processing is easy to make mistakes and the scrapping rate increases, not only the production efficiency is reduced, but also the material cost and the working hour cost are also degraded, which is a great loss for the operator and is very troublesome for the operator.

3, heat-resistant up and down; because the difference between the first and second shells of ABS and the first and second aluminum frame thermal deformation coefficient (thermal expansion coefficient) is too large, so when the suitcase is shipped to the cold zone or tropical countries for sale In this case, it is easy to cause an improper deformation at the intersection of the first outer casing and the first aluminum frame, or at the intersection of the second outer casing and the second aluminum frame, and even a commercial dispute such as a customer sales order occurs.

In view of the fact that the above-mentioned shortcomings of the hard-shell suitcases need to be improved, the inventors have been engaged in the manufacturing development and design experience of related products for many years, and after detailed design and careful evaluation, the present invention has been improved.

The present invention provides a hard-shell suitcase case, comprising: a first outer casing having a first crotch portion and a back plate closing the rear end of the first crotch portion for opening the first outer casing a first chamber facing forward; a first frame, which is integrally formed with a plastic material having a thermal deformation coefficient comparable to that of the first outer casing, and having a first joint portion and a splicing portion; an inner surface loop of the first joint portion Surrounding the outer periphery of the front end of the first crotch portion, and having a first groove for the mounting of the decorative strip on the outer surface thereof, the groove bottom width of the first groove is smaller than the groove top width, and the groove of the first groove The bottom system can be used for the fasteners to wear The frame is fixed to the first crotch portion, and the fastener is covered by the bead ring bundled around the first groove groove bottom; the splicing portion is annularly protruded from the front end of the first crotch portion, and is on the outer surface The annular recess has an assembly groove parallel to the first groove, and the groove bottom of the assembly groove can provide a handle and a hinge installation, and the groove bottom width of the assembly groove is smaller than the groove top width, so that the assembly groove and the first concave The groove can be demolded in the same direction to provide plastic molding; a second outer casing having a second crotch portion and a panel closing the front end of the second crotch portion, the second outer casing having a second chamber having an opening facing rearward And a second frame, which is integrally formed with a plastic material having a thermal deformation coefficient equivalent to that of the second outer casing, and has a second joint portion and an abutting portion respectively, and the inner surface of the second joint portion is wound around the second weir a rear end outer periphery, and a second groove recessed on the outer surface thereof for the other trim strip, the bottom groove width of the second groove is smaller than the groove top width, and the groove bottom of the second groove is The second frame can be fastened to the second crotch by the fastener, and the second frame is wrapped around the second Masking the groove bottom while the fastener; mating annular projecting portion of the second line trunk rear end portion, so that it can derivatives clutch portion, for opening and closing the first two chamber.

Therefore, the present invention has at least the following advantages:

1. Economical benefit: the decorative strip of the invention is fixed by the winding around the corresponding first and second groove bottoms, so the first groove and the second groove can adopt the groove bottom width to be smaller than the groove. The top width is configured so that the first frame and the second frame can be mass-produced by a plastic molding machine, which is naturally more convenient and faster than the conventional process and manual work, so that the present invention can truly revolutionize the height. Creation and industrial utilization are in line with economic benefits.

Second, the non-performing rate is low: Since the first frame and the second frame are processed automatically, it is not only fast and convenient, but also the precision of the slot for the hinge and the handle is better than the conventional one, and the conventional bending is greatly avoided. The rate of non-performing caused by loss of accuracy.

Third, the heat resistance rises and contracts; because the first and second frames of the invention use heat The deformation coefficient is integrally formed with the first and second outer casings of the plastic material, so when the suitcase is shipped to a cold belt or a tropical country, the first outer casing is at the junction with the first frame, or the second outer casing is connected to the second casing. At the same time, it can still maintain the accuracy and appearance of the factory.
