Abstract
The utility model discloses an explosion-proof type batch control instrument. The explosion-proof type batch control instrument comprises an explosion-proof box body, a display screen and a keypad structure, wherein the explosion-proof box body is provided with a window used for displaying the display screen and through holes used for installing the keypad structure, both the display screen and the keypad structure are disposed inside the explosion-proof box body, one end of a keypad extends out of the through holes and explosion-proof glass is arranged on the window. The keypad structure comprises a spring, a spring bayonet used for clamping and holding the spring and a stainless steel button, wherein the stainless steel button passes through the spring and the spring bayonet, and is connected together with the explosion-proof box body.
Description
Technical field
The utility model relates to batch control instrument, relates in particular to a kind of explosion-proof type and criticizes the control instrument.
Background technology
The display screen functions that existing explosion-proof type is criticized the control instrument is single, and button and display screen be design separately, and it can only show simple numeral, character, can not display graphics, can not select to show the font of character, and the product user interface is simple, and aesthetic measure is poor; Button and screen do not integrate in addition, install cumbersome, whole integrated level poor, easily break down, and the programming language of the bottom of application is very high to developer's technical requirement in addition.Increased operation easier from the user, strengthened and safeguarded intensity, versatility is poor from producer, is not easy to Technique Popularizing.
In view of this, provide a kind of Presentation Function complete, aesthetic measure is good, and input, the integrated explosion-proof type of output are criticized the control instrument and necessitated.
The utility model content
The purpose of this utility model provides a kind of explosion-proof type and criticizes the control instrument, can take into account the use of client and producer, has improved the compatibility of product, applicability, and the construction cycle of shortening product is that producer is saved cost of development.
To achieve these goals, the utility model provides a kind of explosion-proof type to criticize the control instrument, comprise anti-explosion box body, display screen, press-key structure, described anti-explosion box body is provided with for the window that shows display screen and is used for the through hole of device press-key structure, described display screen and press-key structure all are arranged in the anti-explosion box body, one end of its button stretches out described through hole, is provided with implosion guard on the described window.
Described press-key structure comprises spring, is used for holding the spring bayonet socket of spring, passes the stainless steel button that spring and spring bayonet socket and described anti-explosion box body link together.
Compare with present technology, a kind of explosion-proof type that is used for chemical industry that the utility model provides is criticized the control instrument, perfect in shape and function, the picture and text of having realized information show, realize the Chinese interface information interaction, and interface is more pressed close to hommization, can make the easier left-hand seat of operator, reduce the ability of popularizing of operator's learning difficulty and enhancing product, thereby increase work efficiency, reduce the human error rate.Compare with existing product, the input of this product, output are set to one, operate more easy.The button of press-key structure 3 is stainless steel, and is durable in use, and cleaning is convenient.
Description of drawings
Accompanying drawing is used for further understanding of the present utility model, and consists of the part of instructions, is used from explanation the utility model with embodiment one of the present utility model, does not consist of restriction of the present utility model.In the accompanying drawings:
A kind of explosion-proof type that Fig. 1 provides for the utility model is criticized the structural representation of control instrument;
Fig. 2 is the section structure for amplifying schematic diagram that a kind of explosion-proof type shown in Figure 1 is criticized the press-key structure of control instrument.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing, it illustrates principle of the present utility model as the part of this instructions by embodiment, other aspects of the present utility model, and feature and advantage thereof will become very clear by this detailed description.
Shown in Fig. 1～2, the utility model provides a kind of explosion-proof type to criticize the control instrument, comprise anti-explosion box body 1, display screen 2, press-key structure 3, described anti-explosion box body 1 is provided with for the window that shows display screen 2 and is used for the through hole of device press-key structure 3, described display screen 2 and press-key structure 3 all are arranged in the anti-explosion box body 1, one end of its button stretches out described through hole, is provided with implosion guard on the described window.
Shown in Fig. 1～2, described press-key structure 3 comprises spring 32, is used for holding the spring bayonet socket of spring 32, passes the stainless steel button 31 that spring 32 and spring bayonet socket and described anti-explosion box body 1 link together.
A kind of explosion-proof type that is used for chemical industry that the utility model provides is criticized the control instrument, perfect in shape and function, the picture and text of having realized information show, realize the Chinese interface information interaction, interface is more pressed close to hommization, can make the easier left-hand seat of operator, reduces the ability of popularizing of operator's learning difficulty and enhancing product, thereby increase work efficiency, reduce the human error rate.Compare with existing product, the input of this product, output are set to one, operate more easy.The button of press-key structure 3 is stainless steel, and is durable in use, and cleaning is convenient.
Disclosed above only is preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim still belongs to the scope that the utility model is contained.
