Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal displays, in particular to a shell tightly fitting device without screws. Background Art

[0002] In the production and assembly process of liquid crystal displays, the stable connection between the front shell and the rear shell is the key link to ensure the overall structural integrity and stability of the display screen. The existing liquid crystal display metal shell screwless tight fitting technology mostly adopts the traditional snap hook type. Although it is also convenient for disassembly and assembly, the snap hook type has a long stroke and requires a large space. If the space is not sufficient and the stroke is insufficient, it cannot be completed. In addition, the hook is easily deformed during processing or transportation due to its small area or thin thickness, which makes it impossible to be normally clipped and hung, causing difficulty in fitting during assembly, requiring plastic processing, and affecting production efficiency. In addition, some product shell screwless tight fitting technology also adopts a gluing fixing method, using glue to bond the two parts together, and fixing the tight fitting shell through the adhesion of the glue. However, after gluing and fixing, although the appearance has achieved screwless tight fitting, it is inconvenient to disassemble and maintain, and cannot be used for the fitting installation of most products. Therefore, we need to propose a shell screwless tight fitting device. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-6 , the utility model provides a technical solution:

[0022] A screw-free tight fitting device for a shell, comprising a front shell 1 and a rear shell assembly 2, wherein the rear shell assembly 2 is arranged inside the front shell 1, a step groove 3 is provided on one side wall of the front shell 1, a plurality of groups of first buckle grooves 4 are provided on one side of the front shell 1, and a second buckle groove 5 is provided on one side of the front shell 1 adjacent to the plurality of groups of first buckle grooves 4, the rear shell assembly 2 comprises a rear shell body 201, the rear shell body 201 is clamped inside the step groove 3, a plurality of groups of studs 202 are provided inside the rear shell body 201, and screws 203 are respectively provided inside the plurality of groups of studs 202, the utility model is fixed to the rear shell body 201 by the studs 202, the screws 203 are locked on the studs 202, the studs 202 are clamped into the first buckle grooves 4 and the second buckle grooves 5 of the front shell 1, so that the head of the screw 203 buckles the front shell 1 to achieve screw-free tight fitting of the shell, thereby effectively avoiding deformation during transportation or processing, and having the characteristic of being easy to disassemble and assemble;

[0023] The rear shell body 201 is provided with a plurality of groups of rivet holes 6 adapted to the studs 202. The plurality of groups of studs 202 are riveted inside the plurality of groups of rivet holes 6 respectively. When riveting, the studs 202 are inserted into the rivet holes 6 and force is applied to deform them to form a head tightly connected to the rear shell body 201. This connection method makes the stress distribution uniform and the connection has high strength and rigidity.

[0024] The inner walls of the plurality of studs 202 are respectively provided with internal threads, the outer walls of the plurality of screws 203 are respectively provided with external threads matching the internal threads, and the plurality of screws 203 are respectively threadedly connected to the interior of the plurality of studs 202;

[0025] Several groups of first buckle slots 4 are all arranged in a trumpet shape, several groups of second buckle slots 5 are all arranged in a gourd shape, one end of several groups of screws 203 are respectively clamped in the inside of the second buckle slots 5, and one end of several groups of studs 202 are respectively clamped in the inside of the first buckle slots 4. By setting the first buckle slots 4, the second buckle slots 5, the studs 202 and the screws 203, the appearance of the display housing can be tightly matched without screws, and a quick assembly connection can be achieved, which effectively avoids deformation during transportation or processing, and has the characteristics of easy disassembly and assembly;

[0026] The size of the front shell 1 is larger than that of the rear shell assembly 2, and the depth of the step groove 3 is consistent with the thickness of the rear shell body 201. Since the size of the front shell 1 is larger than that of the rear shell assembly 2, and the depth of the step groove 3 matches the thickness of the rear shell body 201, this design ensures that the front shell 1 and the rear shell assembly 2 can fit tightly during assembly, reducing the gap caused by size mismatch. The tight fit helps prevent the outer shell from loosening or shifting when subjected to external force or vibration, thereby improving the stability of the entire device.
