Abstract
The utility model relates to an industrial computer display which comprises a front panel (11), a box (8), a liquid crystal display screen (2), a driving circuit board (10), a power (7), a switch (9) and a support (3). The front panel (11) and the box (8) are in fixed connection with the faces contacted tightly, and the box (8) arranged on the support (3) is provided with an explosion-proof interface (5) for cable (4) penetration. The explosion-proof interface (5) is provided with a rubber ring inside (5-3) with a washer (5-1) at the outer side and a gland nut (5-2) screwed at the outlet with the front end supporting on the washer (5-1). The utility model can separate all the flammable and explosive gas from the display box. When accident happens, the explosion inside the display will not influence the explosive gas outside, thereby, the utility model has good explosion-proof capability and image visualization function in the explosion-proof area.
Description
Technical field
The utility model relates to the industrial computer field, specifically, relates to a kind of industrial computer display.
Background technology
Supervisory control system often need be installed in fields such as China's mining industry, oil, chemical industry, military project, space flight, navigation, traffic, scientific research, and the nucleus equipment of supervisory control system is an industrial computer, because the weather in these fields.Environment is more complicated often, particularly to requirement of explosion than higher, and be not tight the contact between the contact-making surface of the front panel of present industrial computer display and casing, inflammable, explosion hazard gases might enter cavity, in addition, also there is the gap between the interface cable of cable and the endoporus of interface, inflammable, explosion hazard gases also may enter cavity from this gap, if the display interior blast can have influence on extraneous explosion gas, the display of this no blast resistance construction is unfavorable for giving full play to image viewing function in explosion-proof area, is unfavorable for full-automatic production in the explosion-proof area.
Summary of the invention
The purpose of this utility model provides the good industrial computer display of a kind of explosion-proof performance.
The technical scheme that realizes above-mentioned purpose is: a kind of industrial computer display, comprise front panel, casing, LCDs, drive circuit board, power supply, switch and support, front panel is fixedlyed connected with casing, casing is rack-mount, the contact-making surface of front panel and casing closely contacts, casing is provided with the explosion-proof interface of threading cable, be provided with rubber ring in this explosion-proof interface, the outside of rubber ring is placed with packing ring, the exit of interface is rotary with clamp nut, and the front end of clamp nut is against on the packing ring.
After adopting technique scheme, closely contact between the contact-making surface of front panel and casing, do not have the slit, inflammable, explosion hazard gases in the adverse circumstances can't enter in the casing between the contact-making surface of front panel and casing.In addition, casing is provided with the explosion-proof interface of threading cable, be provided with rubber ring in this explosion-proof interface, packing ring is placed in the outside of rubber ring, and the exit of interface is rotary with clamp nut, and the front end of clamp nut is against on the packing ring, power line and holding wire are introduced power supply and drive circuit board in the casing from explosion-proof interface, cable passes rubber ring, and screwing between the inwall that clamp nut just can make cable and rubber ring does not have the gap, and inflammable, explosion hazard gases also can't enter casing from explosion-proof interface.Pass through said structure, intercept at display box inflammable, explosion hazard gases external fully, when having an accident, even display interior is blasted, can not have influence on extraneous explosion gas yet, thereby explosion-proof performance is good, helps giving full play to image viewing function in explosion-proof area, and helps the full-automation production in the explosion-proof area.

Fig. 3 is the cutaway view Amplified image of explosion-proof interface of the present utility model;
Fig. 4 is the not cutaway view Amplified image during the threading cable of explosion-proof interface of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As Fig. 1,2, shown in 3, a kind of industrial computer display, comprise front panel 11, casing 8, LCDs 2, drive circuit board 10, power supply 7, switch 9 and support 3, power supply 7 is installed on the power supply pressing plate 6, power supply pressing plate 6 is installed on the casing 8, front panel 11 is fixedlyed connected with casing 8, casing 8 is installed on the support 3, front panel 11 closely contacts with the contact-making surface of casing 8, casing 8 is provided with the explosion-proof interface 5 of threading cable 4, is provided with rubber ring 5-3 in this explosion-proof interface 5, and the outside of rubber ring 5-3 is placed with packing ring 5-1, the exit of explosion-proof interface 5 is rotary with clamp nut 5-2, and the front end of clamp nut 5-2 is against on the packing ring 5-1.Explosion-proof interface 5 on the casing 8 has two, and one is used to wear power cable, and another is used to wear signal cable.
As shown in Figure 1, 2, the position that is positioned at LCDs 2 dead aheads on the front panel 11 is a toughened glass 1, and toughened glass 1 embeds and is installed in the front panel.Toughened glass 1 has better intensity and impact resistance through special processing than simple glass, helps improving the intensity and the impact resistance of display.
As shown in Figure 4, when explosion-proof interface 5 not during threading cable 4, then in the hole of rubber ring 5-3, fill in a stifled core 5-4.As long as screw clamp nut 5-2, just can make between rubber ring 5-3 and stifled core 5-4 does not have the gap, when threading cable not, can intercept at display box inflammable, explosion hazard gases external fully equally, thereby explosion-proof performance is good, has guaranteed the safety of various components and parts in the casing.
Be equipped with several explosion-proof interfaces 5 on the general display, the explosion-proof interface 5 threading cables that have, and have for standby, threading cable when needed, the time spent does not block with stifled core 5-4.
The course of work of the present utility model is as follows: display is started by switch 9 controls, does the signal input by explosion-proof interface 5, by drive circuit board 10 control LCDs 2 display texts, image.
Presentation Function of the present utility model is applicable to multiple shows signal, can be according to the actual needs of explosion-proof area, carry out the function of multimedia display.And be equipped with the interface of varied formula, and applicability is strengthened greatly, the multipurpose that can satisfy under the complex environment is used.
