Abstract
The invention discloses a stud structure of a backplane of a liquid crystal display. The stud comprises a stud and an installation hole in a backplane frame, wherein the stud comprises a screw hole post, and the outer layer of the screw hole post is coated with a casing. The stud structure is characterized in that supporting lugs arranged transversely and clamping edges protruding transversely are arranged at the bottom of the screw hole post and on the casing; both the supporting lugs and the clamping edges are arranged in pairs; adjacent supporting lugs and clamping edges are perpendicular; positioning holes are formed in the supporting lugs; the installation hole is formed in the backplane frame; a notch with a shape and a position corresponding to those of the clamping edges is formed in an outer circle of the installation hole; a positioning convex point is also arranged beside the installation hole; and the position of the convex point corresponds to the positioning hole. The stud structure is easy to mount, convenient to process and high in safety.
Description
Technical field
The present invention relates to a kind of liquid crystal display, the particularly bolt structure on the backboard framework of a kind of LED, LCD display, and the installation method of this double-screw bolt on the backboard framework.
Background technique
The structure of liquid crystal display comprises the backboard framework of TFT LCD and fixer crystal panel, and its dorsulum framework generally is metallic stamping pieces, and the above has double-screw bolt, jog, hole even the process detail such as carve characters.
Wherein, double-screw bolt is a kind of parts that are arranged vertically on the backboard framework, and existing processing method is to adopt punch process.Described bolt structure refer to double-screw bolt and with the general name of the linkage structure of backboard framework.Existing double-screw bolt mainly is that two-part consist of as shown in Figure 1, top screw cylinder and the pedestal of below, and this is a kind of finished product of metalwork, usually also has jagged switch-in part around the pedestal.Installation procedure is such, and at first then punching on the backboard framework inserts double-screw bolt from the below, allow the screw cylinder expose, carry out punching press, pedestal embeds in the plate body of backboard framework after the punching press, form and fix, jagged switch-in part can increase fastness, reduces the plate body distortion.
But existing this technological method needs artificial grafting double-screw bolt to the backboard framework, the punching press of then taking away, and this transports in the process, produces easily positional deviation, in case positional deviation, punching press is failure just, directly reduces product quality.And operator send the backboard framework into punching press, have potential safety hazard.
Summary of the invention
The object of the invention is to invent a kind of easy for installation, accurate positioning, can also reduce manufacturing procedure the display backplane framework bolt structure and based on the installation method of double-screw bolt on the backboard framework of this structure.
This bolt structure of the present invention, comprise the mounting hole on double-screw bolt and the backboard framework, double-screw bolt comprises screw hole column, the screw hole column skin is coated with shell, it is characterized in that: in the bottom of screw hole column, support ear that shell is provided with cross setting and the card edge of lateral projection, support ear and card are along all arranging in pairs, and adjacent support ear and card are along being vertical relation; Have positioning hole on the support ear; The backboard framework is provided with mounting hole, on the cylindrical of mounting hole, is provided with and blocks along shape, breach corresponding to position, and the next door of mounting hole also is provided with positioning convex point; The salient point position is corresponding with positioning hole.
Preferably, between support ear and shell, be provided with deep floor.
Further preferably: described positioning hole arranges one at a support ear.
Manufacture method based on the bolt structure of a kind of display backplane framework of the present invention, at first prepare this double-screw bolt of the present invention, then prepare to be used for the material that the backboard framework is made, use stamping process to rush mounting hole and positioning convex point, the card of double-screw bolt projection is along the breach of the mounting hole from the backboard framework the positioning hole of packing into from top to bottom, then half-twist, the positioning convex point clamping enters the positioning hole on the support ear.
This stud mechanism of the present invention is easy for installation fast, do not have potential safety hazard.

Embodiment
Such as Fig. 2, Fig. 3, this double-screw bolt of the present invention comprises screw hole column 1, and the screw hole column skin is coated with shell 2, and shell generally is plastics, and screw hole column is metal.The bottom of screw hole column, shell are provided with the card of the support ear 3 of cross setting and lateral projection along 4, and support ear 3 and card respectively arrange two all in pairs along 4, and adjacent support ear and card are along being vertical relation; Be provided with deep floor 9 between support ear 3 and the shell 2.The distance that card hangs down the thickness of backboard frameworks along 4 position than support ear 3; Have positioning hole 5 on the support ear 3; Be provided with mounting hole 6 in the place that needs are installed double-screw bolt on the backboard framework, the shape of mounting hole 6 and shell 2 coincide, and on the cylindrical of mounting hole 6, are provided with and block along 4 shapes, breach 7 corresponding to position, and the next door of mounting hole also is provided with positioning convex point 8; Positioning convex point 8 positions are corresponding with positioning hole, are positioned at the outside of breach 7.
The positioning hole 5 of present embodiment and positioning convex point 8 only respectively are provided with one, and positioning hole is arranged on one of them support ear.
Use stamping process to rush mounting hole 5, the card of double-screw bolt projection along 4 from backboard framework top downwards, pack into from top to bottom from the breach 7 of mounting hole 5, at this moment, positioning hole 5 on the support ear 3 and positioning convex point 8 have 90 ° of distances take the screw center as benchmark, support ear 3 contact backboard frame upper surface, card is positioned under the backboard framework lower surface along 4; Then with whole double-screw bolt half-twist, positioning convex point 8 clampings are entered in the positioning hole 5 on the support ear, this moment, card was along the lower surface of 4 clamping backboard frameworks.Finish the processing of whole bolt structure.This technique does not need to carry out punch process, but directly installation, the operation of twice of the punching press of the interruption of original technology can be changed to a punching press like this, obviously can simplify working process, enhance productivity; And install and once finish, avoided the problems such as deviation of two times punch, improve the yield rate of product.At last, installation process need not punching press, can improve Security.
