Technical Field
[0001] This utility model relates to the field of pressure transmitter technology, and in particular to a water-proof structure for a pressure transmitter interface. Background Technology
[0002] A pressure transmitter is a sensing device that converts the pressure parameters of media such as gas and liquid into standard electrical signals. It is used for monitoring and control in industrial automation systems. The pressure transmitter senses the pressure of the medium through a pressure-sensing element sensor and converts it into a standard electrical signal or pneumatic signal. The core conversion principle is based on capacitance change or semiconductor strain effect, and a linear output signal is generated through an oscillation circuit and demodulation stage.
[0003] Existing pressure transmitters are used in various environments. When exposed to humid conditions or outdoors, water can easily enter the connection ports of the pressure transmitter, causing oxidation and corrosion, which reduces its service life. To address this issue, we propose a water-proof structure for the pressure transmitter interface. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water-proof structure for the interface of a pressure transmitter.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A water-proof structure for a pressure transmitter interface includes a pressure transmitter body. A connector is installed on the surface of the pressure transmitter body through a connecting pipe. A connecting mechanism is sleeved on the surface of the connecting pipe, and the surface of the connecting mechanism is connected to one end of a waterproof component. A tightening mechanism is sewn onto the other end of the waterproof component.
[0007] Preferably, the connecting mechanism includes a first connecting disc, the surface of the connecting pipe is fitted with the first connecting disc, and a plurality of mounting bolts are installed inside the first connecting disc.
[0008] Preferably, a sealing gasket is glued to the surface of the first connecting disc, and the sealing gasket is configured as an annular shape.
[0009] Preferably, the waterproof component includes a second connecting plate, the surface of the first connecting plate is mounted with the second connecting plate by mounting bolts, and the surface of the second connecting plate is connected to one end of the protective cover.
[0010] Preferably, the inner wall of the protective cover is sewn with a storage bag, and the surface of the storage bag is sewn with a zipper.
[0011] Preferably, a desiccant is placed inside the placement bag, and a mesh is provided on the surface of the placement bag.
[0012] Preferably, the tightening mechanism includes a tightening ring, the other end of the protective cover is sewn with the tightening ring, and a tie rope is inserted inside the tightening ring, with limit blocks fixedly connected to both ends of the tie rope.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This device allows the protective cover to be easily installed on the surface of the connecting pipe and the insertion pipe by passing the mounting bolts through the first connecting plate and the second connecting plate. At this time, pulling the tightening rope can tighten the tightening ring, thereby securing the outer end of the protective cover and providing waterproof protection for the connection between the connecting pipe and the insertion pipe. At the same time, the sealing gasket glued to the surface of the first connecting plate can increase the sealing between the first connecting plate and the second connecting plate.
[0015] 2. This device allows for easy opening and closing of the storage bag by pulling the zipper. The desiccant can then be placed inside the storage bag, and the mesh screen will absorb and dehumidify, keeping the area inside the protective cover dry for an extended period. The zipper also allows for easy replacement of the desiccant. Attached Figure Description

[0026] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the connecting mechanism 4 includes a first connecting plate 41, the surface of the connecting pipe 2 is fitted with the first connecting plate 41, and a plurality of mounting bolts 42 are installed inside the first connecting plate 41. The second connecting plate 51 can be conveniently installed through the plurality of mounting bolts 42 inserted inside the first connecting plate 41.
[0027] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the surface of the first connecting plate 41 is glued with a sealing gasket 43, and the sealing gasket 43 is set in a circular shape. The sealing gasket 43 can increase the sealing between the first connecting plate 41 and the second connecting plate 51.
[0028] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the waterproof component 5 includes a second connecting plate 51. The surface of the first connecting plate 41 is mounted with the second connecting plate 51 by mounting bolts 42, and the surface of the second connecting plate 51 is connected to one end of the protective cover 52. The protective cover 52 can protect the connection between the connecting pipe 2 and the insertion pipe 3.
