Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings 1-2.

The utility model provides a locking device that liquid crystal display used, the package rubbing board body 1, wherein set up inside sunken display screen standing groove 2 on the plate body 1, 1 lateral wall of 2 intraoral boards of standing groove is cellular structure, evenly be provided with recess 4 on 2 diapire of standing groove, wherein be provided with sucking disc 5 in the recess 4, and sucking disc 5 adsorbs on the back of display screen in standing groove 2.

Place the display screen in standing groove 2 when using and adsorb fixedly by sucking disc 5, thereby prevent that it from can follow the landing in standing groove 2 under the press that does not have external force, with this convenient follow-up installation locking work to the display screen, and sucking disc 5 is unsettled with the display screen back makes it can be abundant with the air contact in order to strengthen its radiating effect, the produced heat in the display screen back can flow through honeycomb aperture on the 1 lateral wall of plate body rapidly simultaneously, thereby accelerate radiating effect and the efficiency at the display screen back, with the service environment that promotes the display screen and prolong its life.

Wherein at the vertical grip block 6 that is provided with of standing groove 2 left and right sides wall, and the grip block 6 back is provided with spring I7 and bolt I8, and is provided with the screw I10 that is used for holding the draw-in groove I9 that corresponds spring I7 end and is used for bolt I8 on the 2 left and right sides wall, bolt I8 head is located the plate body 1 outside and with the screw I10 spiro union that corresponds, wherein spring I7 both ends respectively with draw-in groove I9 diapire and the grip block 6 back fixed connection that corresponds to bolt I8 pole body is terminal to support on the grip block 6 back that corresponds.

Then, the shaft of the bolt I8 is extended into the placing groove 2 by rotating the bolt I8, so that the tail end of the bolt I8 presses the clamping plate 6 to move the clamping plate, and finally, the display screen in the placing groove 2 is clamped and fixed by reducing the distance between the two groups of clamping plates 6 in the placing groove 2, at this time, when the bolt I8 presses the clamping plate 6 to move, the spring I7 is stretched, and when the bolt I8 rotates and returns to the original position, the spring I7 contracts to drive the clamping plate 6 to return to the original position, in the process, the clamping plate 6 is used for enlarging the contact area between the clamping plate 6 and the left and right side edges of the display screen to reduce the pressure, so that when the display screen is clamped and fixed in the placing groove 2 through the bolt I8 and the clamping plate 6, the problem that the pressure of a certain single area is too large due to the small stress area is avoided. The catch I9 is used to hold the spring I7 against skewing or sliding during the above process.

And a supporting plate 11 is arranged on the side wall of the bottom of the placing groove 2, wherein the bottom of the supporting plate 11 is provided with a spring II12 and a bolt II13, the side wall of the bottom of the placing groove 2 is provided with a clamping groove II14 for accommodating the tail end of the corresponding spring II12 and a screw hole II15 for the bolt II13 to pass through, the head of the bolt II13 is positioned on the outer side of the plate body and is in threaded connection with the corresponding screw hole II15, two ends of the spring II12 are fixedly connected with the bottom wall of the corresponding clamping groove II14 and the bottom wall of the supporting plate 11, and the tail end of the shaft of the bolt II13 abuts.

Then, the shaft of bolt II13 is extended into placement groove 2 by rotating bolt II13, so that the end of bolt II13 presses support plate 11 to move upward, and finally, the display screen in placement groove 2 is clamped and fixed by reducing the distance between support plate 11 and the top wall of placement groove 2, at this time, when bolt II13 presses support plate 11 to move, spring II12 is stretched, and when bolt II13 rotates and returns to the original position, spring II12 contracts to drive support plate 11 to return to the original position, in the above process, the contact area between support plate 11 and the bottom edge of the display screen is increased to reduce the pressure, so that when the display screen is clamped and fixed in placement groove 2 by bolt II13 and support plate 11, the problem that the pressure of a single area is too large due to the small stress area and the display screen is crushed is avoided. The clamping groove II14 is used for fixing the spring II12 to prevent the spring II from skewing or sliding in the process.

Preferably, a notch 3 communicated with the placing groove 2 is arranged at the middle of the top of the placing groove.

As a preferred scheme, all be provided with the protection on standing groove 2 diapire and the lateral wall and fill up, grip block 6 and backup pad 11 all are provided with the protection on the surface and fill up. So as to prevent the display screen from being damaged by the parts.

The using method of the invention is that the display screen is placed in the placing groove 2 between the two groups of clamping plates 6 and the supporting plate 11 and is absorbed and fixed by the sucking disc 5, thereby preventing the display screen from sliding from the placing groove 2 under the pressing without external force, then the rod body of the display screen extends into the placing groove 2 by rotating the bolt I8, the tail end of the bolt I8 extrudes the clamping plates 6 to move, finally the display screen in the placing groove 2 is clamped and fixed by reducing the distance between the two groups of clamping plates 6 in the placing groove 2, and further the bolt is rotated

II13 has its shaft extended into the placement tray 2 so that the end of bolt II13 presses the support plate 11 to move it upward, and finally the display screen in the placement tray 2 is clamped and fixed by narrowing the space between the support plate 11 and the top wall of the placement tray 2.

The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and is not to be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
