Description

Technical Field

[0001] The utility model relates to the technical field of pressure transmitters, in particular to a pressure transmitter component. Background Art

[0002] Pressure transmitter refers to a pressure sensor with a standard output signal. It is an instrument that receives pressure variables and converts them into standard output signals in proportion. It can convert physical pressure parameters such as gas and liquid sensed by the pressure measuring element sensor into standard electrical signals to supply secondary instruments such as indicator alarms, recorders, and regulators for measurement, indication, and process regulation. Pressure transmitters are widely used in many industries such as water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military industry, petrochemicals, oil wells, electricity, ships, machine tools, pipelines, etc.

[0003] However, in actual use of the prior art, the pressure transmitter is a field instrument that is in direct contact with the measured medium and often works in environments such as high temperature, low temperature, corrosion, vibration and impact. At the same time, since the exterior of an ordinary pressure transmitter is composed of an ordinary housing and a dashboard that displays the measured values, the ordinary pressure transmitter has poor protection capabilities and is easily prone to changes in measurement accuracy or damage due to collisions or impacts, thereby affecting the service life of the pressure transmitter. Utility Model Content

[0004] The purpose of the utility model is to provide a pressure transmitter assembly to solve the problem that the pressure transmitter proposed in the above background technology is a field instrument that is in direct contact with the measured medium and often works in an environment of high temperature, low temperature, corrosion, vibration, impact, etc. At the same time, since the exterior of an ordinary pressure transmitter is composed of an ordinary shell and an instrument panel that displays the measured value, the ordinary pressure transmitter has poor protection capabilities and is easily prone to changes in the measurement accuracy or damage of the pressure transmitter due to collision or impact, thereby affecting the service life of the pressure transmitter.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a pressure transmitter body and a fixed bottom plate, a protective box for protecting the pressure transmitter body is fixedly installed in the middle of the upper end surface of the fixed bottom plate, a limiting slot is provided in the middle of the front and rear ends of the protective box, a sealing cover plate is magnetically connected to the upper end of the protective box, and a sealing strip is movably connected to the inner wall of the limiting slot;

[0006] A limited straight slide groove is provided at the bottom of the protection box, and the inner wall of the limited straight slide groove is rotatably connected to a transmission screw through a rotating shaft. The outer top end of the transmission screw passes through the bottom side end of the protection box and is fixedly installed with a knob. The outer curved surfaces at both ends of the transmission screw are threadedly connected with sliders, and a clamping plate is fixedly installed on the top of the slider, and a buffer pad is bonded to the inner end of the clamping plate.

[0007] Preferably, fixing holes are formed through the four corners of the fixed base plate, and there are four fixing holes, which are symmetrically distributed at the four corners of the fixed base plate, so that the fixed base plate can be installed and fixed through the fixing holes and connecting bolts.

[0008] Preferably, there are two limit slots, which are symmetrically distributed in the middle of the front and rear ends of the protection box, and the front and rear end connecting pipe parts of the pressure transmitter body are movably connected to the inner wall of the lower end of the limit slot.

[0009] Preferably, a handle is fixedly installed in the middle of the upper end of the sealing cover plate, and the upper top of the sealing strip is fixedly installed in front of and behind the lower end of the sealing cover plate.

[0010] Preferably, a transparent glass window is embedded and fixedly installed through the upper side of the front end surface of the protection box, so that the measured value of the instrument panel part of the pressure transmitter body can be observed from the outside through the transparent glass window.

[0011] Preferably, the outer curved surface at the outer end of the transmission screw is threadedly connected with a fastening nut for locking and fastening the transmission screw.

[0012] Preferably, the outer curved threads at both ends of the transmission screw are in opposite directions, there are two sliders, which are symmetrically distributed at both ends of the transmission screw, and both side ends of the sliders are movably connected to the inner wall of the limiting straight sliding groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. When the protective box needs to be opened to inspect and maintain the pressure transmitter body, the sealing cover is pulled upward by the handle. When the sealing cover is pulled upward, the sealing cover moves upward to open and drives the sealing strip to move upward along the inner wall of the limit slot. When the sealing strip moves upward, the limit slot can be opened synchronously, thereby realizing protection of the pressure transmitter body while facilitating opening the protective box to inspect and maintain the pressure transmitter body;

[0015] 2. When the drive screw is rotated by the knob, the utility model will drive the slider to move synchronously outward or inward along the inner wall of the limiting straight slide groove due to the force generated by the opposite directions of the outer curved threads at both ends of the drive screw and the connection of the outer curved threads at both ends of the drive screw. When the slider moves synchronously outward or inward in a straight line, it will drive the clamping plate to move synchronously outward or inward. When the clamping plate moves synchronously outward or inward, it will drive the buffer pad to clamp the pressure transmitter body stably, thereby protecting the pressure transmitter body while clamping the pressure transmitter body stably.
