Abstract
The utility model discloses a stud structure of a backing plate of a liquid crystal display. The stud structure comprises a stud and a mounting hole in a backing plate frame, wherein the stud comprises a screw hole column, and an outer layer of the screw hole column is coated with a housing. The stud structure is characterized in that transversely arranged support lugs and transversely raised clamp edges are arranged at the bottom of the screw hole column and on the housing pairwise; the adjacent support lugs and the clamp edges are perpendicular; a locating hole is formed in one support lug; the mounting hole is formed in the backing plate frame; notches corresponding to the clamp edges in shapes and positions are formed at an excircle of the mounting hole; a locating bump is arranged beside the mounting hole; and a position of the bump corresponds to the locating hole. The stud structure is simple to mount, convenient to process and high in safety.
Description
Technical field
The utility model relates to a kind of liquid crystal display, particularly the bolt structure on the backboard framework of a kind of LED, LCD display.
Background technique
The structure of liquid crystal display comprises the backboard framework of TFT LCD and fixer crystal panel, and its dorsulum framework is generally metallic stamping pieces, and the above has double-screw bolt, jog, the hole process detail such as even 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 as shown in Figure 1, is mainly that two-part form, top screw cylinder and the pedestal of below, and this is a kind of finished product of metalwork, the pedestal surrounding also has jagged switch-in part usually.Installation procedure is such, and at first punching on the backboard framework, then insert double-screw bolt from below, allow the screw cylinder expose, carry out punching press, after punching press, pedestal embeds in the plate body of backboard framework, form and fix, jagged switch-in part can increase fastness, reduces the plate body distortion.
But existing this technological method, need artificial grafting double-screw bolt to the backboard framework, the punching press of then taking away, this transports in process, easily produces positional deviation, once positional deviation, punching press is failure just, directly reduces product quality.And operator send the backboard framework into punching press, there is potential safety hazard.
The model utility content
The purpose of this utility model is to invent a kind of easy for installation, accurate positioning, can also reduces the bolt structure of the display backplane framework of manufacturing procedure.
This bolt structure of the present utility model, comprise the mounting hole on double-screw bolt and backboard framework, double-screw bolt comprises screw hole column, the screw hole column skin is coated with shell, it is characterized in that: on the bottom of screw hole column, shell, be provided with the support ear of 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 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 side of mounting hole also is provided with positioning convex point; The salient point position is corresponding with positioning hole.
Preferably, be provided with deep floor between support ear and shell.
Further preferably: described positioning hole arranges one on a support ear.
Only need be by the card of double-screw bolt projection along the breach of the mounting hole from the backboard framework the positioning hole of packing into from top to bottom when bolt structure of the present utility model is used, then half-twist, the positioning hole that the positioning convex point clamping enters on support ear can complete fixed installation, fast and easy, there is no potential safety hazard.
The accompanying drawing explanation
Fig. 1, existing bolt structure.
Fig. 2, the sectional drawing of double-screw bolt of the present utility model.
Fig. 3, overall structure figure of the present utility model.
Embodiment
As Fig. 2, Fig. 3, this double-screw bolt of the present utility model comprises screw hole column 1, and the screw hole column skin is coated with shell 2, and shell is generally 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 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 support ear 3; Be provided with mounting hole 6 in the place of needs installation 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 side 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 the present embodiment and positioning convex point 8 only respectively are provided with one, and positioning hole is arranged on one of them support ear.
Manufacture and installation process: use stamping process to rush mounting hole 5, the card of double-screw bolt projection along 4 from backboard framework top downwards, from the breach 7 of mounting hole 5, pack into from top to bottom, now, positioning hole 5 on support ear 3 and positioning convex point 8 be take the screw center has 90 ° of distances as benchmark, support ear 3 contact backboard frame upper surface, card is positioned under backboard framework lower surface along 4; Then by whole double-screw bolt half-twist, positioning convex point 8 clampings are entered in the positioning hole 5 on support ear, now block along the lower surface of 4 clamping backboard frameworks.Complete the processing of whole bolt structure.This technique, do 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 to complete, avoided the problems such as deviation of two times punch, improve the yield rate of product.Finally, installation process need not punching press, can improve Security.
