Technical Field
The utility model relates to a fixing structure of a display screen, in particular to a fixing structure of a PCB (printed circuit board) with a display screen on a panel of a case.
Background
At present, need install the display screen of an inch on some communication machine case panels to indicating device's behavior, the display screen passes through the flexonics with the PCB board, because some display screens do not fix to the PCB board through certain fixing device, if direct PCB board direct mount that will have the display screen like this needs to be fixed through the mode that glue is pasted, its reliability is poor, and under the abominable condition of high temperature or environment, the display screen drops easily. In view of the above problems, how to reasonably design a mechanical fixing structure of a display screen becomes a technical problem to be solved by the present invention.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a fixing structure of a PCB with a display screen on a panel of a chassis, which has the specific technical scheme that the fixing structure of the PCB with the display screen on the panel of the chassis comprises a fixing frame and a display panel, and is characterized in that: the fixing frame is a frame with a distance-shaped groove on one end surface, rectangular windowing through holes on the bottom end surface of the groove and an extension plate with positioning through holes at four corners, the display panel is a rectangular transparent plate with the outer side surfaces of the periphery provided with extension plates with equal width and equal thickness, a boss at the rear end of the display panel is inserted into the windowing through hole of the fixing frame for positioning and matching, the back end surface of the display panel is flush with the bottom end surface of the groove of the fixing frame, the extension plate of the display panel and the front boss of the extension plate are inserted into the display plate hole of the chassis panel for positioning and matching, and the front end surface of the boss of the display panel is flush with the front end surface of the case panel, four positioning through holes of the fixing frame are sleeved on four positioning riveting studs on the rear end surface of the case panel, when in use, the display screen of the PCB with the display screen is inserted into the groove of the fixing frame, and the PCB with the display screen is fixed on the four positioning riveting studs on the rear end surface of the panel of the chassis by screws.
The utility model has the technical effects of improving the reliability, firmly fixing the display screen and not influencing the display function of the display screen.

Detailed Description
The present invention will be explained in detail below with reference to the accompanying drawings.
As shown in fig. 1, fig. 2, fig. 3 and fig. 4, a fixing structure of a PCB board with a display screen on a panel of a chassis includes a fixing frame 1 and a display panel 2, wherein the fixing frame 1 is made of aluminum alloy and is formed by milling; the display panel 2 is made of a transparent plastic PC, and is machined and the surface thereof is polished.
The fixing frame 1 is a frame with a distance-shaped groove 1-1 on one end surface, a rectangular windowing through hole 1-2 on the bottom end surface of the groove 1-1 and an extension plate with positioning through holes 1-3 on four corners.
The display panel 2 is a rectangular transparent plate with outer side faces of the periphery provided with epitaxial plates with equal width and equal thickness.
The boss 2-2 at the rear end of the display panel 2 is inserted into the windowing through hole 1-2 of the fixing frame 1 for positioning and matching, the back end face of the display panel 2 is flush with the bottom end face of the groove 1-1 of the fixing frame 1, the extension plate 2-1 of the display panel 2 and the front boss 2-3 of the extension plate are inserted into the display plate hole 4-2 of the chassis panel 4 for positioning and matching, and the front end surface of the boss 2-3 of the display panel 2 is flush with the front end surface of the case panel 4, four positioning through holes 1-3 of the fixing frame 1 are sleeved on four positioning riveting studs 4-1 on the rear end surface of the case panel 4, when in use, a display screen 3-1 of a PCB board 3 with the display screen is inserted into a groove 1-1 of a fixing frame 1, and the PCB 3 with the display screen is fixed on four positioning riveting studs 4-1 on the rear end surface of the case panel 4 by screws 5.
As shown in fig. 5, which is a schematic diagram of the embodiment of the present invention for matching with a communication chassis panel, after the fixing frame 1 is matched with the display panel 2, i.e., the mechanical combination structure, the structure is matched with the corresponding positioning riveting stud 4-1 on the communication chassis panel 4, i.e., the four positioning through holes 1-3 on the fixing frame 1 are sleeved on the four positioning riveting studs 4-1 on the chassis panel 4.
As shown in fig. 6 and 7, a display screen 3-1 of the PCB 3 with the display screen is fitted into a groove 1-1 of the fixing frame 1, and the PCB 3 with the display screen is fixed to a positioning rivet stud 4-1 of the chassis panel by using a screw.
In summary, the present invention is only an embodiment of the present invention, and the designer can optimize or improve the technical solution according to the teaching of the above example.
