A kind of pressure unit being convenient to installation wireless moduleTechnical field
The utility model relates to pressure unit field, is specifically related to a kind of pressure unit being convenient to install wireless module.
Background technology
pressure unit refers to export the pressure transducer into standard signal, it a kind ofly accepts the instrument that pressure variations is converted to standard output signals in proportion, the physical pressure parameter such as gas, liquid that load cell can be experienced by it is transformed into the electric signal of standard, carries out measuring, indicating and procedure regulation to supply the secondary instruments such as indicator alarm, registering instrument, regulator.Current pressure unit is wired connection mostly, need data line to realize the transmission of signal, so not only make data receiver inconvenient, and especially when this pressure unit be in relatively far away outdoor time, not only want the data line of at substantial, and relatively more easily there is Signal reception problem in data line.Therefore, also there are some wireless pressure transmitter successively at present, but, existing wireless pressure transmitter price is relatively expensive, although wired pressure unit exists some problems really, consider for price, most of user still selects wired pressure unit.
Utility model content
The purpose of this utility model is to provide a kind of pressure unit being convenient to install wireless module, the inner chamber of this pressure unit to existing wired pressure unit improves, existing wireless module is placed in inner chamber dexterously, and do not affect the general layout of original inner chamber, install very convenient, effectively can reduce the cost of wireless pressure transmitter.
The utility model for achieving the above object, realizes by the following technical solutions:
A kind of pressure unit being convenient to installation wireless module, comprise the end cap that cavity and two are separately positioned on cavity two ends, the lower end of cavity is provided with the connection base for being fixed on by cavity on pipeline, cavity is also provided with the display for showing variable parameter and the connector for inlet wire, the middle part of described cavity is provided with parting bead, the two ends of described parting bead are provided with cushion block, cushion block, parting bead are all close to the inwall of cavity, the interior of described cavity is also provided with arc, and arc and cushion block are positioned on same perpendicular.
In this programme, by improving existing wired pressure unit, especially cavity is improved, on the basis not changing original pressure unit interior, by arranging parting bead, cushion block and arc in cavity, wireless module can be placed in cavity just, under the effect of end cap, wireless module is clamped, is fixed on the space place formed between end cap and arc, simultaneously, because parting bead and arc do not block inside cavity space, the heat therefore in cavity well can be scattered and disappeared with the opening on end cap or pore; Cushion block, on the basis of playing a supporting role, contacts with wireless module with exceeding, and makes the components and parts of wireless module can not be subject to too much compressing, serves certain protective effect to wireless module, also enables the heat of wireless module scatter and disappear preferably simultaneously.
Further, preferably, described cavity is cylindric, and the shape of cross section of cushion block is fan-shaped, and the central axis of cavity is in the xsect of cushion block.
Further, preferably, a described cushion block is equal with the thickness of arc with the thickness of parting bead.
Further, preferably, two sides that described parting bead is relative with arc are parallel to each other.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) the utility model is by improving the cavity of existing wired pressure unit, existing wireless module can be held, like a cork wired pressure unit is become wireless pressure transmitter, compare current wireless pressure transmitter, price is lower, practicality is stronger, can meet the demand of general user to wireless pressure transmitter.
(2) the utility model is by arranging parting bead, cushion block and arc by the cavity of existing wired pressure unit, by the mating reaction with end cap, not only achieve wireless module fixing in cavity well, also do not affect the radiating efficiency of wireless module simultaneously, effectively can improve the repacking space of wired pressure unit to wireless pressure transmitter.

Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment:
As Fig. 1, shown in Fig. 2, a kind of pressure unit being convenient to installation wireless module described in the present embodiment, comprise the end cap 2 that cavity 1 and two are separately positioned on cavity 1 two ends, the lower end of cavity 1 is provided with the connection base 3 for being fixed on by cavity on pipeline, cavity 1 is also provided with the display 4 for showing variable parameter and the connector 5 for inlet wire, the middle part of cavity 1 is provided with parting bead 6, the two ends of parting bead 6 are provided with cushion block 7, cushion block 7, parting bead 6 is all close to the inwall of cavity 1, the interior of cavity 1 is also provided with arc 8, arc 8 and cushion block 7 are positioned on same perpendicular, wireless module is placed in cavity 1, and with cushion block 7, arc 8 is affixed, now the end cap 2 at cavity 1 two ends is screwed on, after wireless module being fixed on cavity 1, the power lead that wireless module is corresponding with in cavity 1 connects, existing wired pressure unit then easily can be adapted as wireless pressure transmitter, wireless module is available circuit plate structure.
As preferably, the cavity 1 of the present embodiment is cylindric, and the shape of cross section of cushion block 7 is fan-shaped, and the central axis of cavity 1 is in the xsect of cushion block 7.
A cushion block 7 of the present embodiment is equal with the thickness of arc 8 with the thickness of parting bead 6.
Two sides that the parting bead 6 of the present embodiment is relative with arc 8 are parallel to each other.
The above; it is only preferred embodiment of the present utility model; not do any pro forma restriction to the utility model, every any simple modification, equivalent variations done above embodiment according to technical spirit of the present utility model, all falls within protection domain of the present utility model.
