Description

Technical Field

[0001] The utility model relates to the technical field of mechanical design, in particular to a mass flow meter transmitter fixing device. Background Art

[0002] With the continuous advancement of industrial automation and process control technologies, mass flowmeters play a vital role in a variety of industries, including chemical, petroleum, pharmaceutical, and food processing. Their high precision, high stability, and reliable performance make them the preferred device for flow measurement. In recent years, with increasing demands for production efficiency and product quality, market demand for mass flowmeters has continued to grow, driving the rapid development of the industry. However, a long-standing problem has gradually emerged during the production and installation of mass flowmeters: the connection between mass flow transmitters and connector heads often uses an M20 threaded connection. Due to slight deviations in the thread manufacturing process, it is difficult to ensure that the front of the transmitter faces completely forward after installation. This not only affects the overall aesthetics of the device, but can also cause measurement errors due to improper installation, reducing the accuracy and reliability of the instrument. Therefore, how to achieve precise positioning of the transmitter while ensuring connection strength has become a key issue hindering the performance improvement and widespread application of mass flowmeters.

[0003] In response to the above problems, traditional technology has adopted a compromise solution: on the basis of M20 threaded connection, an M3 set screw is added to assist in fixing the transmitter. The specific steps are: first, use the M20 thread to roughly install the transmitter on the connector head, and then manually adjust the position of the transmitter so that its front faces as straight forward as possible. After completing the initial positioning, use the M3 set screw to pass through the reserved hole on the transmitter and screw it into the connector head or nearby structure to provide additional fixing force to help keep the position of the transmitter stable. Although this method alleviates the problem of transmitter offset to a certain extent, the tightening strength of the set screw is limited. In the face of long-term external forces (such as vibration, temperature changes, etc.), the transmitter may still have slight offsets, affecting the overall appearance and measurement accuracy of the mass flowmeter. Therefore, exploring a more reliable and efficient connection method has become a technical problem that needs to be solved urgently in the industry.

[0004] In summary, how to solve the technical problem that the front of the transmitter cannot face straight ahead after the transmitter and the sensor are tightened is an issue that needs to be solved urgently. Utility Model Content

[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] According to the mass flow meter transmitter fixing device provided by the embodiment of the present utility model, Figure 1 、 Figure 2As shown, the present invention provides a mass flowmeter transmitter fixing device, comprising: a sensor 10, a connector assembly 20, and a transmitter 30, wherein the sensor 10 is placed in a preset position; the connector assembly 20 comprises: a rotary connecting component 21 and a fixed sleeve 22, wherein the first end of the rotary connecting component 21 abuts against the sensor 10, the first end of the fixed sleeve 22 is connected to the sensor 10, and the rotary connecting component 21 is fixedly placed inside the fixed sleeve 22; the bottom of the transmitter 30 is connected to the second end of the rotary connecting component 21, and the second end of the fixed sleeve 22 abuts against the bottom end surface of the transmitter 30; wherein the rotary connecting component 21 is used to fix the transmitter 30 and adjust the transmitter 30 to a preset forward direction, and the fixed sleeve 22 is used to fix the rotary connecting component 21 in the preset position of the sensor 10 so as to connect the sensor 10 to the transmitter 30. In a specific implementation, the first end of the rotary connecting component 21 is tightly abutted against the sensor 10, ensuring a stable and reliable connection between the two. The design of the swivel connection component 21 allows for rotational adjustment within a certain range, allowing the transmitter 30 to be adjusted to the preset forward orientation. This feature is particularly important when precise alignment or adjustment of the mounting angle is required. The material and structural design of the fixed sleeve 22 should be sufficiently strong to withstand the weight of the transmitter 30 and possible external forces. During installation, the sensor 10 is first placed in the preset position. Then, the swivel connection component 21 is placed inside the fixed sleeve 22, and the bottom of the transmitter 30 is connected to the second end of the swivel connection component 21. By adjusting the rotation angle of the swivel connection component 21, the transmitter 30 is adjusted to the preset forward orientation. Next, the first end of the fixed sleeve 22 is connected to the sensor 10, and the second end of the fixed sleeve 22 is used to press downward on the second end of the swivel connection component 21 to ensure the stability and firmness of the entire device. This device solves the technical problem of the front of the transmitter not facing forward after the transmitter and sensor are tightened, thereby ensuring that the transmitter can face forward after the transmitter and sensor are tightened.

[0024] Specifically, the bottom of the sensor 10 has a cylindrical internal thread structure. In a specific implementation, the second end of the rotary connection component 21 can have a cylindrical external thread structure. The transmitter 30 and the second end of the rotary connection component 21 are connected via the cylindrical internal thread structure and the cylindrical external thread structure to ensure a stable and reliable connection between the transmitter 30 and the rotary connection component 21.

[0025] Specifically, the second end of the rotary connection component 21 has a cylindrical external thread structure, and the transmitter 30 and the second end of the rotary connection component 21 are connected via a cylindrical internal thread structure and a cylindrical external thread structure. In practice, the second end of the rotary connection component 21 is connected to the cylindrical internal thread structure at the bottom of the sensor 10 to ensure a stable and reliable connection between the transmitter 30 and the rotary connection component 21.

[0026] Specifically, the internal space of the fixed sleeve 22 is seamlessly matched with the rotary connection component 21 to limit and fix the rotary connection component 21. It can be understood that the benefit of doing so is to ensure that the rotary connection component 21 does not shake up and down or left and right inside the fixed sleeve 22, thereby ensuring the stability and reliability of the device.

[0027] Specifically, the fixed sleeve 22 is a hollow truncated cone, with the first end of the fixed sleeve 22 having a smaller opening, and the second end of the fixed sleeve 22 having a larger opening. The swivel connecting member 21 is a stepped cylinder, with the end of the swivel connecting member 21 having a smaller radius serving as the second end. The second end of the swivel connecting member 21 passes through the hole in the first end of the fixed sleeve 22 and connects to the cylindrical internal thread structure at the bottom of the sensor 10. The circular stepped surface of the second end of the swivel connecting member 21 fits tightly against the inner surface of the first end of the fixed sleeve 22 within the fixed sleeve 22 to secure the swivel connecting member 21. In practice, the fixed sleeve 22 is first designed as a hollow truncated cone. This design feature ensures that the sleeve has two openings of different sizes. Specifically, the first end of the fixed sleeve 22 has a smaller opening, while the second end has a larger opening. This design not only facilitates installation and disassembly but also provides a certain degree of structural stability and support. Next, the swivel connection component 21 is designed in the shape of a stepped cylinder. This design gives the swivel connection component 21 two different radii, with the end with the smaller radius defined as the second end of the swivel connection component 21. This stepped design facilitates subsequent connection and fixation. During the actual assembly process, the second end of the swivel connection component 21 (i.e., the end with the smaller radius) is designed to pass through the first end (the end with the smaller opening) of the fixed sleeve 22. During this process, the second end of the swivel connection component 21 is connected to the cylindrical internal thread structure at the bottom of the sensor 10. This connection method is usually achieved through threaded mating, ensuring the firmness and stability of the connection. In addition, to ensure the stability and firmness of the swivel connection component 21 within the fixed sleeve 22, the circular stepped surface of the second end of the swivel connection component 21 is designed to tightly fit with the inner surface of the first end of the fixed sleeve 22 inside the fixed sleeve 22. This tight fit not only provides additional fixing force but also effectively prevents the swivel connection component 21 from shaking or falling off during use. In summary, this embodiment fully discloses the technical solution of the present invention by describing in detail the specific shapes and dimensions of the fixed sleeve 22 and the rotary connection member 21, as well as the connection method therebetween. This structural design not only ensures a secure connection between the sensor 10 and the rotary connection member 21, but also improves the stability and reliability of the entire device through the support and fixation provided by the fixed sleeve 22.

[0028] Specifically, the second end of the fixing sleeve 22 is evenly circumferentially provided with multiple screw holes, which are used by screws 23 to secure the fixing sleeve 22 to a predetermined position on the sensor 10. As will be appreciated, this approach ensures a stable and reliable connection between the fixing sleeve 22 and the sensor 10, further ensuring the stability and reliability of the entire device.

[0029] It can be understood that the mass flow meter transmitter fixing device provided by the utility model is compared with the traditional mass flow meter transmitter fixing device. The mass flow meter transmitter fixing device provided by the utility model solves the technical problem that the front of the transmitter cannot face forward after the transmitter and the sensor are tightened, thereby ensuring that the transmitter can face forward after the transmitter and the sensor are tightened.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
