[0002] As a type of pressure transmitter, explosion-proof pressure transmitter is widely used in petrochemical, electric power, metallurgy, pharmaceutical, food processing and other industries. When the pressure transmitter needs to be able to withstand huge pressure, it is necessary to use an explosion-proof pressure transmitter. In order to ensure that the explosion-proof pressure transmitter can work stably, its connection must not be easy to loosen.

[0003] Although the existing equipment can prevent the connection and fixing parts from loosening, the position of the fixing structure is relatively fixed, resulting in inflexible installation.

[0004] For example, an explosion-proof pressure transmitter with Chinese utility model application number CN202222762937.5 includes a horizontal plate and an explosion-proof pressure transmitter, wherein the left side of the outer wall of the horizontal plate is connected to a fixed structure, the front of the fixed structure is connected to a rotating rod, the bottom of the explosion-proof pressure transmitter is integrally formed with a connecting rod, the fixed structure includes a curved plate and a stud, the inner side of the curved plate is rotationally connected to the left side of the outer wall of the horizontal plate, the inner side of the curved plate is rotationally connected to the outer wall of the stud, the outer wall of the stud is respectively threaded with a clamping plate, the inner wall of the clamping plate is slidably clamped with a straight plate, and the right side of the straight plate is fixedly connected to the left side of the curved plate. The relatively fixed position of the fixing structure of the equipment leads to inflexible installation. Utility Model Content

[0005] The purpose of the utility model is to provide an explosion-proof pressure transmitter to solve the problems raised in the background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an explosion-proof pressure transmitter, comprising:

[0007] A pressure transmitter body, wherein a hoop ring is sleeved on the lower part of the pressure transmitter body;

[0008] Two corresponding fixing parts are integrally formed at the opening of the hoop, and a fastening screw is screwed between the two fixing parts, a connecting rod is connected to one side of the fixing part, and a connecting column is sleeved on the side wall of the connecting rod, a plurality of adjustment holes are arranged side by side on one side of the connecting rod, corresponding fixing holes are arranged on the outer wall of the connecting column, and hand screws are screwed between the fixing holes and the corresponding adjustment holes, a mounting plate is welded to the end of the connecting column away from the hoop, and two rows of mounting holes are arranged side by side on one side of the mounting plate.

[0009] In a further embodiment, two limiting rings are integrally formed side by side at the lower portion of the pressure transmitter body, and the two limiting rings are located on both sides of the hoop ring.

[0010] In a further embodiment, the pressure transmitter body and the limit ring, and the hoop ring and the fixing member are all cast as an integral structure.

[0012] In a further embodiment, a protective ring is bonded to the corresponding side of the instrument of the pressure transmitter body, and the protective ring is flush with the edge of the instrument.

[0013] In a further embodiment, a stud is welded to one end of the connecting rod, and a screw hole for threading the stud is configured on one side of the hoop.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] The existing scheme of the explosion-proof pressure transmitter improves stability by clamping and fixing with an additional fixing structure, but the relative position of the structure is fixed, which is not flexible enough when installing and fixing in an actual environment, resulting in inconvenient installation. The present scheme can adjust the rotation of the hoop to adjust the installation direction of the mounting plate, and can also adjust the sliding of the connecting column on the side wall of the connecting rod to adjust the installation distance of the mounting plate, so that the operation is more flexible and convenient during installation and fixing, and the position of the fixing structure can be adjusted to make the installation more flexible;

[0016] The explosion-proof pressure transmitter has an adjustable position of the fixing structure, making the installation more flexible. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0026] In order to fix the position of the structure, the installation can be adjusted to make it more flexible, such as Figures 1 to 3 As shown: a pressure transmitter body 1, a mounting rod 13 is installed at the bottom of the pressure transmitter body 1, and the pressure transmitter body 1 can be threadedly connected to the external structure through the mounting rod 13. A protective ring 14 is bonded to the corresponding side of the instrument of the pressure transmitter body 1, and the protective ring 14 is flush with the edge of the instrument, which can provide protection for the glass of the instrument to prevent the glass from being worn.

[0027] A hoop 2 is sleeved on the lower part of the pressure transmitter body 1, and two corresponding fixing parts 3 are integrally formed at the opening of the hoop 2, and a fastening screw 4 is screwed between the two fixing parts 3. The two fixing parts 3 are locked by the fastening screw 4, so that the hoop 2 can be tightened to the corresponding side of the pressure transmitter body 1, and a connecting rod 5 is connected to one side of the fixing part 3, and a stud 11 is welded at one end of the connecting rod 5. A screw hole for screwing the stud 11 is constructed on one side of the hoop 2, which is convenient for disassembly and assembly of the connecting rod 5.

[0028] A connecting column 6 is sleeved on the side wall of the connecting rod 5, and the connecting column 6 can slide relative to the connecting rod 5 to adjust the installation distance of the mounting plate 9.
