Description
Technical field
The present invention relates to a kind of digital display manometer, relate in particular to a kind of digital display manometer housing.
Background technology
Tensimeter is to measure and indicate the instrument that is higher than environmental pressure.Present tensimeter great majority on the market all are pointer tensimeters, but pointer pressure is not suitable for the pressure that detects the media such as liquid, gas and steam that corrosive attack is arranged, and has not vibration resistance, parallax is arranged during reading, can only estimate and read, poor reliability, the shortcomings such as need are maintenance and difficult in maintenance often, and sensitivity is poor.Generally use digital display manometer abroad, it has fundamentally overcome shortcomings such as the pointer pressure precision is low, poor reliability, spoilage height are fit to the detection of multiple occasion pressure, especially use more aobvious its performance free from worldly cares in places such as burn into vibrations.But it also has a lot of deficiencies, be arranged on the bottom surface of digital display manometer housing such as its place of installing and fixing of existing digital display manometer, the back side that wire inlet-outlet is arranged on housing is the bonnet of housing, the shortcoming of design is this space resources of the back side that wire inlet-outlet has taken housing like this, to such an extent as to digital display manometer can only have the pressure viewing area and can not be designed to the two-sided form that all has the pressure viewing area by single face; The place of installing and fixing and wire inlet-outlet divide and are arranged in addition, the structural design of such digital display manometer housing is more unreasonable, when maintenance, generally need to open the bonnet of housing, and have wire inlet-outlet and line taken certain space and blocked certain sight line at bonnet this moment, and operating personnel are inconvenient when opening bonnet and maintenance.For this reason, how to provide a kind of simple in structure, reasonable in design, can the double-sided display force value and digital display manometer housing easy to use become research topic of the present invention.
Summary of the invention
The object of the invention provides a kind of digital display manometer housing, and its purpose is to solve existing digital display manometer shell structure design problem unreasonable, inconvenience when can only single face showing force value and use or maintenance.
For achieving the above object, the technical solution used in the present invention is: a kind of digital display manometer housing, this housing mainly is made of protecgulum and bonnet amalgamation, the outer face of the protecgulum of housing is the front of housing, the outer face of the bonnet of housing is the back side of housing, be fixedly connected with after protecgulum and the bonnet amalgamation, be provided with the first pressure viewing area on the outer face of described protecgulum, in the bottom surface of described protecgulum or bonnet to being arranged with one or two erection column, this erection column inside is provided with through hole in the axial direction, one end of this through hole is communicated with the inner chamber of protecgulum or bonnet, other end opening, an erection column end in the axial direction is fixedly connected with the bottom surface outer rim of protecgulum or bonnet as link, and the other end is positioned at protecgulum as sealed end or bonnet is outside, and the outer rim of described erection column is provided with for the screw thread of installing; Be provided with the second pressure viewing area on the described bonnet.
Related content in the technique scheme is explained as follows:
1. in the such scheme, an end of described through hole is communicated with the inner chamber of protecgulum or bonnet, other end opening, wherein " externally " refer to the outside of housing.
2. in the such scheme, also be provided with sealing strip in the mosaic of described protecgulum and bonnet, protecgulum is screwed with bonnet and is connected.
3. in the such scheme, be socketed with the nut that matches with described screw thread on the described erection column outer rim; Be socketed with on the sealed end outer rim of described erection column with rubber seal sealing nut.The inside of described sealing nut is with rubber seal, and this rubber seal can be tightened up inlet wire or outlet, thereby plays the effect of sealing.
4. in the such scheme, be provided with one to three button on the protecgulum of described housing, the end face of button protrudes from the outer rim of described protecgulum, and button is used for controlling the numeral demonstration of described the first pressure viewing area and the second pressure viewing area.
Design concept of the present invention and beneficial effect are: for solve existing digital display manometer shell structure design unreasonable, use or the problem of inconvenient operation during maintenance, overall design design of the present invention merges into a single whole the place of installing and fixing and wire inlet-outlet exactly.
Specific design is contemplated that the bottom surface of described housing is provided with one or two erection column, and described erection column is fixedly connected with substrate as the place of installing and fixing of digital display manometer.Again because described erection column is a through hole in the axial direction, namely can be by inlet wire and outlet in through hole, so erection column also is the wire inlet-outlet of digital display manometer.When described digital display manometer housing was provided with an erection column, this erection column was not only as incoming line but also as line outlet; When described digital display manometer housing was provided with two erection columns, one of them erection column was as incoming line, and another erection column is as line outlet.So just reserve spendable space resources for the back side of described digital display manometer housing, can be provided with a pressure viewing area on the back side of housing, described digital display manometer can carry out double-sided display, therefore also can check immediately pressure condition at this moment during in the operation of the back side of digital display manometer as the technician, and needn't check around the front to digital display manometer.In addition, open at needs in the situation of digital display manometer housing, as the digital display manometer that needs repairing, owing to not had wire inlet-outlet and line to take certain space at bonnet and having blocked certain sight line, operating personnel can take protecgulum or the bonnet of housing apart easily, needn't employ inlet wire and outlet, also guarantee safety and the durability of circuit.The present invention is simple in structure, reasonable in design, can the double-sided display force value, and use or easy to operate during maintenance.
