Abstract
The utility model relates to a pressure transmitter. Two nameplates are respectively and symmetrically arranged at two sides of the shell of the pressure transmitter, a mounting bracket is arranged at the connection end of the shell of the pressure transmitter and a sensor, external grounding terminals are respectively and symmetrically arranged at two side ends of the mounting bracket, two explosion-proof card mounting frames are symmetrically cast at the upper and the lower ends of the mounting bracket, a groove is arranged at the connection part between the explosion-proof card mounting frames and the shell of the pressure transmitter, mounting bracket screw holes are respectively arranged at outer end surfaces of the explosion-blocking proof mounting frames, one end of an explosion-proof card is positioned in the groove, the inner side of the outer end surface of the mounting bracket is provided with screw threads, and a pressure sensor is connected with the screw threads. The utility model has the advantages that as the mounting bracket takes a round shape, the mould manufacture is simple, the mould processing precision is reduced, the raw materials are saved, the cost of the sheel of the pressure transmitter is reduced, and the requirements for small, lightweight and portable pressure transmitter with low price and high quality in the present market are satisfied.
Description
Technical field
The utility model relates to a kind of pressure unit, particularly a kind of pressure unit shell.
Background technology
Square structure is adopted in existing pressure unit housing and sensor coupling part, and the transmitter nameplate has three, type nameplate, explosion-proof nameplate and range nameplate.The type nameplate is assemblied in the cable input end face of housing, and explosion-proof nameplate is assemblied in the blind end surface of housing, and the range nameplate is assemblied in the front end face of housing.Transmitter external ground link is positioned at the right side of housing front and rear end, is used for the right side that explosion-proof card erecting frame is positioned at the housing front/rear end, and the mounting bracket that transmitter is connected with pipeline is installed the diagonally opposing corner place that screw is positioned at the housing below; Therefore the shell mechanism of pressure unit has caused certain degree of difficulty to mfg. moulding die owing to be square, and Mould Machining accuracy requirement height, and because the square casing volume is bigger, and materials are more, therefore because the cost of raw and processed materials height makes transmitter housing cost strengthen; Therefore three nameplates have strengthened the workload of system board and assembling, and the expense of making nameplate is strengthened; Two screw diagonally opposing corners of the existing mounting bracket of pressure unit are on the rectangular planes of housing bottom, and difficulty of processing is bigger, and the screw location is not easy, and has brought the certain difficulty degree to processing.
Summary of the invention
In view of the problem that prior art exists, the utility model provides a kind of external structure more to be tending towards a kind of pressure unit that rationalizes.
The technical scheme that the utility model is taked for achieving the above object is: a kind of pressure unit, comprise pressure transducer, the pressure unit shell, explosion-proof card, it is characterized in that: described pressure unit shell both sides are arranged with two nameplates respectively, be provided with mounting bracket at transmitter shell and sensor link, the two side ends of mounting bracket is arranged with the external ground terminal respectively, on the mounting bracket, following two ends symmetry is cast with two explosion-proof card erecting frames, two explosion-proof card erecting frames and transmitter shell junction are provided with groove, two explosion-proof card erecting frame outer faces are respectively equipped with the mounting bracket screw, described explosion-proof card one end places in the groove, inboard, mounting bracket outer face is provided with screw thread, described pressure transducer be threaded.
The beneficial effects of the utility model are: the sensor junction is for being shaped as circular shell, mfg. moulding die is simple like this, the Mould Machining precision has reduced, starting material had both been saved, reduced transmitter housing cost, also make transmitter small and exquisite, light, satisfied that current market demand is small and exquisite, light, the demand of inexpensive transmitter.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the explosion-proof card structure synoptic diagram of the utility model.
Embodiment
As Fig. 1, shown in 2, a kind of pressure unit comprises pressure transducer, pressure unit shell 1, explosion-proof card 9 constitutes, pressure unit shell 1 two side ends is arranged with two nameplates 4 respectively, nameplate is a rectangle, be provided with garden shape mounting bracket 2 at transmitter shell 1 and sensor link, the two side ends of mounting bracket 2 is arranged with external ground terminal 3, on the mounting bracket 2, following two ends vertical symmetry respectively are cast with two explosion-proof card erecting frames 5, two explosion-proof card erecting frames 5 offer groove 6 with transmitter shell 1 junction, two explosion-proof card erecting frame 5 outer faces offer mounting bracket screw 7 respectively, one end of two explosion-proof card 9 band screws is inserted respectively in two recessed 6 grooves and is screwed, and the other end blocks transmitter cover; Mounting bracket 2 is provided with screw thread 8 for circular at circular outer ends face madial wall, and an end of the outer silk of pressure transducer band is connected with screw thread 8.
The utility model pressure unit, change original three nameplates into two nameplates, explosion-proof nameplate and range nameplate and type nameplate be merged into nameplate 4, and change rectangle into by original square, and, reduce the mould of nameplate starting material and processing nameplate with nameplate 4 size decreases; Transmitter external ground terminal 3 is arranged on mounting bracket 2 both sides and is convenient to the user installation use;
Screw 7 is positioned at explosion-proof card erecting frame 5 and extends housing lower surface flush position downwards, and the screwhole position after the improvement is easy to process and be convenient to install.
