Abstract
The utility model relates to an electronic product liquid crystal display, aiming at solving the technical problems that cracks, even disconnection, etc. are generated between a front shell and a rear shell when the buckle is used for connecting in prior art. The utility model comprises the front shell and the rear shell of the display; the internal wall of the front shell is provided with a convex buckle; the rear shell is provided with a corresponding blocking trough. The utility model is characterized in that the two sides of the buckle of the front shell are respectively provided with position limit tenons, the top of which are provided with position limit bulges. As the utility model adopts the structure, the position limit bulge effectively prevents the movement of the rear shell of the display, the crack is not generated, and the front shell and the rear shell which are buckled with each other are tightly attached to each other. Furthermore, the utility model has the advantages of simple structure and convenient disassembly and assembly.
Description
Technical field
The utility model relates to the electronic product LCD, specifically to a kind of improvement of available liquid crystal display.
Background technology
Can often use LCD in existing electronic product such as computing machine, the cashing machine, existing LCD generally includes fore shell and back cover, and fore shell can be connected by screw or buckle with back cover.It is the buckle that is provided with outstanding strip on fore shell that buckle connects, and has corresponding draw-in groove on the back cover, and buckle is installed in the draw-in groove, so that forward and backward shell installing and locating.Because the buckle attended operation is convenient, tool using not, products appearance fairing, brief simultaneously, compactness is well positioned to meet the more and more thinner trend of LCD outward appearance, is therefore extensively adopted by manufacturer.But this buckle connection makes and is easy to produce the slit between the forward and backward shell, has a strong impact on the presentation quality of product, even occurs threading off, and buckle structure was lost efficacy.
The utility model content
The purpose of this utility model is in order to solve buckle that prior art exists and to connect, and easily produces the slit between the forward and backward shell, even technical matters such as dropout occurs, and provide a kind ofly can prevent the LCD that buckle is deviate from effectively.
In order to solve the problems of the technologies described above, the utility model is achieved by the following technical solutions:
A kind of LCD, it comprises display front-housing and back cover, the fore shell inwall is provided with outstanding buckle, has corresponding draw-in groove on the back cover, it is characterized in that: described fore shell buckle both sides are respectively equipped with spacing muscle, and spacing muscle top is provided with spacing preiection.
In the further detailed structure of the utility model, also have following technical characterictic: described spacing preiection and spacing muscle are integral type, and it is trapezoidal that spacing preiection is.
In the further detailed structure of the utility model, also have following technical characterictic: the height b of described spacing preiection is 1.5-2mm, the angle of chamfer between the spacing preiection back cover inwall
Be 10-30 °.
In the further detailed structure of the utility model, also have following technical characterictic: described buckle is a strip, and its cross section is trapezoidal.
Compared with prior art, the utlity model has following advantage and good effect:
Because the utility model has adopted said structure, the setting of spacing block set has prevented moving of display back cover effectively, can not produce the slit, and the forward and backward shell that clamps is mutually closely fit together.In addition, the utility model is simple in structure, easy accessibility.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Referring to Fig. 1-Fig. 5, the utility model LCD comprises display front-housing 10 and back cover 20, and fore shell 10 inwalls are provided with outstanding strip buckle 11, and buckle 11 cross sections are trapezoidal.Have corresponding draw-in groove 21 on the back cover 20, fore shell buckle 11 both sides are respectively equipped with spacing muscle 12, and spacing muscle 12 tops are provided with spacing preiection 13, and spacing preiection 13 is an integral type with spacing muscle 12, and spacing preiection 13 is trapezoidal.For the setting that makes spacing preiection 13 can not produce too much influence to the dismounting of buckle 11, to the height and the gradient of spacing preiection 13 certain restriction be arranged, the angle of chamfer between spacing preiection 13 and back cover 20 inwalls
Be 10-30 °, the height b of spacing preiection 13 is 1.5-2mm, and its apart from back cover 20 inwalls apart from a, can be directly proportional with the thickness d that overlaps of buckle 11 mating parts, generally be it half.
During installation, fore shell 10 is pressed down, because fore shell 10 is generally working of plastics, utilize its elastic deformation that buckle 11 is installed in the draw-in groove 21 of back cover 20, spacing preiection 13 just in time can block back cover 20, prevents that it from moving.During dismounting, only need earlier back cover 20 is rotated counterclockwise certain angle, treat that spacing preiection 13 is crossed in back cover 20 bottoms after, promptly removable buckle 11.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
