Description

Technical Field

[0001] This utility model relates to the field of pressure transmissions, and more specifically, to an adjustable pressure transmitter. Background Technology

[0002] A pressure transmitter is an instrument that converts pressure variables into a standard, transmittable output signal. Its technological background stems from the industrial demand for precise pressure measurement and control. Early pressure measuring devices were mechanical, but these suffered from low accuracy, slow response, and difficulty in long-distance signal transmission. With the development of electronic, sensor, and signal processing technologies, pressure transmitters emerged. They utilize pressure-sensitive elements to convert pressure changes into electrical signals, which are then amplified and linearized into standard electrical signals (such as 4-20mA or 0-10V) for output, achieving high precision, high reliability, and long-distance transmission in pressure measurement.

[0003] Existing pressure transmitters have exposed through-slots and lack protective features. In industrial production environments, numerous factors can potentially cause physical damage to the pressure transmitter. For example, in areas where machinery operates, the movement or collision of equipment may impact the pressure transmitter, leading to its failure. Therefore, we have made improvements by proposing an adjustable pressure transmitter. Utility Model Content

[0004] The purpose of this utility model is to address the existing problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] Adjustable pressure transmitters can improve the above-mentioned problems.

[0007] The present invention is as follows:

[0008] The device includes a pressure transmitter body, comprising a main body, a digital display screen, a first connector, and a second connector. A protective shell is provided on the front of the pressure transmitter body, and transparent glass is adhered to the protective shell. A first insert rod is fixedly installed on the top of the back of the protective shell, and a second insert rod is fixedly installed on the bottom of the back of the protective shell. A mounting plate is fixedly connected to the top of the main body, and a bidirectional threaded rod is provided above the mounting plate. Threaded plates are threaded to both ends of the bidirectional threaded rod, and locking rods are fixedly installed on the side walls of the threaded plates. An end cap is threadedly connected to the back of the main body, and a hexagonal ring is fixedly connected to the outside of the end cap. Grooves are evenly formed on the hexagonal ring, and a convex ring is also fixedly connected to the end cap, with evenly formed circular grooves on its outer wall.

[0009] As a preferred technical solution of this utility model, a first socket is fixedly installed on the top of the mounting plate, and the first plug rod matches the slot on the first socket.

[0010] As a preferred technical solution of this utility model, a second socket is fixedly connected to the bottom of the main body, and the second plug rod matches the slot on the second socket.

[0011] As a preferred technical solution of this utility model, both ends of the bidirectional threaded rod are rotatably connected to auxiliary seats, and the auxiliary seats are fixedly installed on the top of the first socket.

[0012] As a preferred technical solution of this utility model, a throttle is fixedly installed at one end of the bidirectional threaded rod.

[0013] As a preferred technical solution of this utility model, a guide rail is fixedly installed on the top of the mounting plate.

[0014] As a preferred technical solution of this utility model, the bottom of the threaded plate is provided with a guide groove, which matches the guide rail.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the solution of this utility model:

[0017] 1. By installing the protective housing, the first insert rod is inserted into the slot on the first socket, and the second insert rod is inserted into the slot on the second socket. Then, rotating the handle causes the bidirectional threaded rod to rotate, which in turn moves the threaded plate outward. Simultaneously, the threaded plate moves the locking rod, causing the locking rod to pass through the first socket and the first insert rod in sequence. This facilitates the installation of the protective housing and effectively prevents direct impact from external forces, thus avoiding the risk of transmitter housing breakage and internal component damage. It solves the problem of existing pressure transmitters having exposed through-slots and lacking protective functions. In industrial production environments, there are many factors that can cause physical damage to pressure transmitters. For example, in areas where machinery operates, the movement or collision of equipment may impact the pressure transmitter, leading to damage.

[0018] 2. By designing a hexagonal ring with grooves, a raised ring, and a circular groove on the raised ring, the end cover can be opened for maintenance by holding the hexagonal ring with fingers positioned in the groove on the outer ring for easy rotation. If it cannot be opened by hand, a wrench can be used to clamp the hexagonal ring and rotate it to open the end cover. Alternatively, a cylindrical rod or other tool can be inserted into the circular groove on the raised ring for rotation. This design offers multiple ways to open the end cover and avoids situations where it cannot be opened by hand. Attached Figure Description

[0033] Example:

[0034] like Figure 1-7 As shown, this embodiment proposes an adjustable pressure transmitter, including a pressure transmitter body 1. The pressure transmitter body 1 includes a main body 101, a digital display screen 102, a first connector 103, and a second connector 104. A protective shell 4 is provided on the front of the pressure transmitter body 1, and a transparent glass 19 is adhered to the protective shell 4. The transparent glass 19 is installed to facilitate viewing the values ​​on the digital display screen 102. A first insert rod 5 is fixedly installed on the top of the back of the protective shell 4, and a second insert rod 6 is fixedly installed on the bottom of the back of the protective shell 4. Both the first insert rod 5 and the second insert rod 6 serve to facilitate the installation of the protective shell 4. A mounting plate 7 is fixedly connected to the top of the main body 101, and a bidirectional threaded rod 20 is provided above the mounting plate 7. Both ends of the bidirectional threaded rod 20 are threaded with screws. The threaded plate 8 and the bidirectional threaded rod 20 rotate to move the threaded plate 8. A locking rod 9 is fixedly installed on the side wall of the threaded plate 8, and the threaded plate 8 drives the locking rod 9. The back of the main body 101 is threadedly connected to the end cover 2. A hexagonal ring 3 is fixedly connected to the outside of the end cover 2. Grooves 16 are evenly opened on the hexagonal ring 3. Hold the hexagonal ring 3 with your fingers in the grooves 16 on the outer ring of the hexagonal ring 3, which makes it easy to rotate. If you cannot open it by hand, you can use a wrench to clamp the hexagonal ring 3 and rotate it to open the end cover 2. A convex ring 17 is also fixedly connected to the end cover 2. The outer wall of the convex ring 17 is evenly opened with round grooves 18. You can also use a cylindrical rod or other tools to insert into the round grooves 18 on the convex ring 17 to rotate it. The advantage of this is that there are multiple ways to open the end cover 2, avoiding the situation where it cannot be opened by hand.

[0035] A first socket 10 is fixedly installed on the top of the mounting plate 7. A first plug 5 matches the slot on the first socket 10. When installing the protective shell 4, the first plug 5 is inserted into the slot on the first socket 10. A second socket 15 is fixedly connected to the bottom of the main body 101. A second plug 6 matches the slot on the second socket 15. The second plug 6 is inserted into the slot on the second socket 15.

[0036] Auxiliary seats 11 are rotatably connected to both ends of the bidirectional threaded rod 20. The auxiliary seats 11 are used to install the bidirectional threaded rod 20 and are fixedly installed on the top of the first socket 10.

[0037] A throttle 12 is fixedly installed at one end of the bidirectional threaded rod 20, and the throttle 12 drives the bidirectional threaded rod 20.

[0038] A guide rail 13 is fixedly installed on the top of the mounting plate 7, and a guide groove 14 is provided at the bottom of the threaded plate 8. When the threaded plate 8 moves, the guide groove 14 at the bottom slides along the guide rail 13, and the guide groove 14 matches the guide rail 13.

[0039] In this embodiment, the pressure transmitter body 1 is manufactured by Lantian County Hengyuan Hydropower Equipment Co., Ltd., and its model is MPM483. This product can adjust its range. Its structure, principle and usage are existing technologies and will not be described in detail here.

[0040] Specifically, this adjustable pressure transmitter allows for range adjustment during use. After installation, the protective housing 4 is installed, with the first insertion rod 5 inserted into the slot on the first socket 10 and the second insertion rod 6 inserted into the slot on the second socket 15. Then, the handle 12 is rotated, which drives the bidirectional threaded rod 20 to rotate. The bidirectional threaded rod 20 rotates, which drives the threaded plate 8 to move outward. As the threaded plate 8 moves, the bottom guide groove 14 slides along the guide rail 13. At the same time, the threaded plate 8 drives the locking rod 9, which passes through the first socket 10 and the first insertion rod 5 in sequence. This fixes the first insertion rod 5 inside the first socket 10, preventing the protective housing 4 from falling off. After installation, it can effectively avoid the risk of the transmitter housing breaking or internal components being damaged due to direct impact from external forces.

[0041] When it is necessary to open the end cover 2 for maintenance, hold the hexagonal ring 3 with your fingers inside the groove 16 on the outer ring of the hexagonal ring 3. This makes it easy to rotate. If you cannot open it by hand, you can use a wrench to hold the hexagonal ring 3 and rotate it to open the end cover 2. Alternatively, you can use a cylindrical rod or other tools to insert into the circular groove 18 on the convex ring 17 and rotate it. The advantage of this is that there are multiple ways to open the end cover 2, avoiding the situation where it cannot be opened by hand.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
