Description

Technical Field

[0001] This utility model belongs to the technical field of differential pressure transmitter training device, and more specifically, it relates to a differential pressure transmitter calibration and commissioning training device. Background Technology

[0002] A differential pressure transmitter is a precision industrial measuring instrument widely used in chemical, petroleum, and power industries. It measures the differential pressure of fluids or gases in pipelines and converts it into a standard signal output, thereby achieving accurate measurement of parameters such as flow rate, liquid level, and pressure. Differential pressure transmitters are characterized by accurate measurement, adjustable range, and stable performance. Their standardized structural design ensures high interchangeability and facilitates installation and maintenance. Furthermore, they can output a standard 4-20mA current signal, allowing for easy connection and communication with various control systems and instruments. However, operating a differential pressure transmitter requires a certain level of proficiency, so practical training on a training platform is necessary.

[0003] Based on the above, the inventors have discovered the following problems: Current differential pressure transmitter training devices typically consist of two parts: an operating table and a mounting frame. When these two parts are not in use, the display screen and controller on the operating table are precision components, so they need to be placed in a place with less dust. When they are needed, the two parts are combined. However, existing differential pressure transmitter training devices usually require bolts for assembly, which is quite troublesome.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a differential pressure transmitter calibration and commissioning training device in order to achieve a more practical value. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a differential pressure transmitter calibration and commissioning training device, which solves the problem that current differential pressure transmitter training devices are cumbersome to assemble.

[0006] The purpose and effectiveness of this utility model, a differential pressure transmitter calibration and commissioning training device, are achieved through the following specific technical means:

[0007] A differential pressure transmitter calibration and commissioning training device includes an operating table and a mounting frame. The mounting frame is equipped with a training and assessment unit. The operating table includes a pair of first support legs and a pair of second support legs. The mounting frame includes a pair of third support legs and a pair of fourth support legs. The first support legs and the third support legs are connected by a combination mechanism.

[0008] Furthermore, the combined mechanism includes a first slot on the surface of the first support leg and a second slot on the surface of the third support leg. A rotating plate is mounted on the surface of the first slot via a rotating shaft. The mechanism also includes a cavity on the surface of the second slot, in which a spring is installed. A locking block is installed at the end of the spring away from the cavity. A locking groove is formed on the surface of the rotating plate. The mechanism also includes a straight groove on the surface of the third support leg, extending into the cavity. A push block is formed on the surface of the locking block, with one end of the push block extending outward through the straight groove.

[0009] Furthermore, the first support leg, the second support leg, the third support leg, and the fourth support leg are made of iron.

[0010] Furthermore, a pre-fixing mechanism is installed on the surface of the rotating plate.

[0011] Furthermore, the pre-fixing mechanism is a pair of magnets mounted on the surface of the rotating plate.

[0012] Furthermore, the surfaces of the first support leg, the second support leg, the third support leg, and the fourth support leg are coated with an anti-rust coating.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes a combination mechanism. When the operating table and mounting frame need to be combined, the casters at the bottom of the operating table and mounting frame move to align the first and third support legs. Then, a push block is pushed to move within the straight groove. The movement of the push block causes a locking block to move into the cavity, at which point the spring contracts. Then, the rotating plate is rotated. When one side of the rotating plate contacts the top edge of the second slot, the locking slot aligns with the locking block. The push block is then released, and the spring resets, causing the locking block to reset, thus locking the locking block into the locking slot. When both rotating plates are fixed, the operating table and mounting frame are secured. When it is necessary to separate the operating table and mounting frame, simply release the fixing of the rotating plates. This design allows for quick combination of the operating table and mounting frame, improving work efficiency. Attached Figure Description

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0028] As attached Figure 1 To be continued Figure 4 As shown:

[0029] This utility model provides a differential pressure transmitter calibration and commissioning training device, including an operating table 1 and a mounting frame 2. The mounting frame 2 is provided with a training and assessment unit 3. The operating table 1 includes a pair of first support legs 101 and a pair of second support legs 102. The mounting frame 2 includes a pair of third support legs 201 and a pair of fourth support legs 202. The first support legs 101 and the third support legs 201 are connected by a combination mechanism.

[0030] The combined mechanism includes a first slot 401 on the surface of the first support leg 101 and a second slot 402 on the surface of the third support leg 201. A rotating plate 403 is mounted on the surface of the first slot 401 via a rotating shaft. The mechanism also includes a chamber 404 on the surface of the second slot 402. A spring 405 is installed in the chamber 404. A locking block 406 is installed at the end of the spring 405 away from the chamber 404. A locking groove 407 is formed on the surface of the rotating plate 403. The mechanism also includes a straight groove 408 on the surface of the third support leg 201, which extends into the chamber 404. A push block 409 is formed on the surface of the locking block 406, with one end of the push block 409 extending outward through the straight groove 408.

[0031] By using the combination mechanism, when the operating table 1 and the mounting frame 2 need to be combined, the universal wheels at the bottom of the operating table 1 and the mounting frame 2 are used to move them, aligning the first support leg 101 and the third support leg 201. Then, the push block 409 is pushed to move within the straight groove 408. The movement of the push block 409 will cause the locking block 406 to move into the chamber 404. At this time, the spring 405 contracts. Then, the rotating plate 403 is rotated. When one side of the rotating plate 403 contacts the top edge of the second slot 402, the locking groove 407 aligns with the locking block 406. Then, the push block 409 is released. At this time, the spring 405 returns to its original position, causing the locking block 406 to return to its original position, thereby locking the locking block 406 into the locking groove 407. When both rotating plates 403 are fixed, the operating table 1 and the mounting frame 2 can be fixed together. When it is necessary to separate the operating table 1 and the mounting frame 2, it is only necessary to release the fixing of the rotating plates 403. Through the above design, the operating table 1 and the mounting frame 2 can be quickly combined, improving work efficiency.

[0032] The first support leg 101, the second support leg 102, the third support leg 201, and the fourth support leg 202 are made of iron.

[0033] The pre-fixing mechanism consists of a pair of magnets 5 mounted on the surface of the rotating plate 403.

[0034] By using magnet 5, when the rotating plate 403 is located in the first slot 401, magnet 5 can attract the iron first support leg 101, preventing the rotating plate 403 from moving when the operating table 1 moves.

[0035] The surfaces of the first support leg 101, the second support leg 102, the third support leg 201, and the fourth support leg 202 are coated with an anti-rust coating.

[0036] The use of rust-preventive coatings can extend the service life of the product.

[0037] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
