Description

Technical Field

[0001] This utility model is a transmitter, belonging to the field of transmitters. Background Technology

[0002] A transmitter is a device that converts sensor output signals into standard signals. It is commonly used in industrial automation control systems. The main function of a transmitter is to convert non-electrical signals, such as temperature, pressure, and flow, into electrical signals for remote measurement and control. A transmitter is also known as a transmitter connector. This type of connector has a threaded end and a welded short pipe at the other end. The welded short pipe is welded to the transmitter interface, and the threaded end is connected to the pipe connection port. Transmitter adapters are one of the most commonly used connectors for transmitters, mainly used for conversion connections between various pressure gauges and pressure transmitters.

[0003] However, in most existing technologies, transmitter adapters and connecting pipes are connected by threads. When the flow inside the connecting pipe is flowing, the connecting pipe will vibrate, which can cause the threaded end of the adapter to easily reverse. This can lead to loosening after long-term use, reducing the stability of the device installation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a transmitter to solve the problems mentioned in the background art. This utility model ensures that the nut will not reverse and will not loosen after long-term use, thereby improving the stability of the device installation.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a transmitter, including a connecting pipe, a transmitter body and a transfer pipe, wherein an installation pipe is fixedly sleeved on the outer wall of the connecting pipe, the outer wall of the installation pipe is provided with a first thread, an installation plate is fixedly connected to the bottom of the transmitter body, the outer wall of the transfer pipe is provided with a second thread, a nut is threaded onto the outer wall of the second thread, and a limit component is provided at the bottom of the installation plate.

[0006] The limiting component includes a hinge fixedly connected to the bottom of the mounting plate, a limiting plate fixedly connected to one side of the hinge, a second slot provided on the outer wall of the limiting plate, a first slot provided at one end of the limiting plate, and a fixing component provided on the top of the nut.

[0007] Furthermore, a display is provided on one side of the transmitter body, and the outer wall of the adapter pipe is movably engaged with the inner wall of the installation pipe.

[0008] Furthermore, the fixing component includes a fixing bracket fixedly connected to the top of the nut, the inner bottom wall of the fixing bracket having a first groove, and the inner wall of the first groove having a first spring retaining bead.

[0009] Furthermore, a sealing element is fixedly fitted onto the outer wall of the adapter pipe, and the top of the adapter pipe is fixedly connected to the bottom of the mounting plate.

[0010] Furthermore, a support component is provided at the bottom of the mounting plate, the support component including a support frame fixedly connected to the bottom of the mounting plate, the support frame having a "U" shaped structure.

[0011] Furthermore, the inner wall of the support frame is provided with a second groove, and the inner wall of the second groove is provided with a second spring retaining bead, which is movably engaged with the second groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. Rotate the nut. The downward movement of the nut will cause its threaded groove to engage with the outside of the installation pipe. The threaded groove of the nut will connect with the first thread, thus allowing the transmitter body to be installed on the connecting pipe. Rotate the limiting plate. The second groove will disengage from the second spring retaining ball, allowing the limiting plate to be rotated to a vertical position. One end of the limiting plate will rotate into the interior of the fixing frame. The first spring retaining ball will engage with the interior of the first retaining groove, thus limiting the position of the limiting plate. The limiting plate will fix the distance between the nut and the mounting plate, preventing the nut from turning backward and ensuring that it will not loosen over a long period of use, thereby improving the stability of the device installation.

[0014] 2. Part of the limiting plate is snapped into the inside of the support frame. The limiting plate presses the second spring retaining bead, which then engages with the inside of the second groove. This allows the limiting plate to be positioned so that it does not automatically change its angle, thus further meeting the usage requirements of the device. Attached Figure Description

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1-6 This utility model provides a technical solution: a transmitter, including a connecting pipe 1, a transmitter body 4, and a transfer pipe 18. An installation pipe 2 is fixedly sleeved on the outer wall of the connecting pipe 1. A first thread 3 is formed on the outer wall of the installation pipe 2. An installation plate 6 is fixedly connected to the bottom of the transmitter body 4. A second thread 15 is formed on the outer wall of the transfer pipe 18. A nut 16 is threadedly sleeved on the outer wall of the second thread 15. A threaded channel is formed on the top of the nut 16. The nut 16 is sleeved on the outer wall of the second thread 15 through the threaded channel. When the nut 16 is rotated, it moves on the second thread 15 through the threaded channel. The downward movement of the nut 16 causes its thread groove to be sleeved on the outside of the installation pipe 2. The thread groove of the nut 16 is threadedly connected to the first thread 3, thereby realizing the installation of the transmitter body 4 on the connecting pipe 1. A limit component is provided at the bottom of the installation plate 6.

[0025] The limiting component includes a hinge 7 fixedly connected to the bottom of the mounting plate 6. A limiting plate 8 is fixedly connected to one side of the hinge 7. The limiting plate 8 will rotate through the hinge 7. A second slot 10 is provided on the outer wall of the limiting plate 8. A first slot 9 is provided at one end of the limiting plate 8. A fixing component is provided on the top of the nut 16.

[0026] A display 5 is provided on one side of the transmitter body 4, and the outer wall of the adapter pipe 18 is movably engaged with the inner wall of the installation pipe 2. The transmitter body 4 can sense the signal, and its data will be displayed on the display 5.

[0027] The fixing component includes a fixing bracket 12 fixedly connected to the top of the nut 16. The inner bottom wall of the fixing bracket 12 is provided with a first groove 13. The inner wall of the first groove 13 is provided with a first spring retaining bead 14. When the first spring retaining bead 14 is subjected to greater resistance, it will move into the interior of the first groove 13. After the force is no longer applied, the first spring retaining bead 14 will return to its original position.

[0028] A sealing element 17 is fixedly fitted to the outer wall of the adapter pipe 18. The top of the adapter pipe 18 is fixedly connected to the bottom of the mounting plate 6. The sealing element 17 is made of a rubber sealing ring with a good sealing effect. When the adapter pipe 18 is fitted inside the installation pipe 2, the sealing element 17 can seal the gap between the adapter pipe 18 and the installation pipe 2. The transmitter body 4 is installed together with the adapter pipe 18 through the mounting plate 6.

[0029] The bottom of the mounting plate 6 is provided with a support component, which includes a support frame 11 fixedly connected to the bottom of the mounting plate 6. The support frame 11 has a "U" shaped structure. A part of the limiting plate 8 is snapped into the inside of the support frame 11. The limiting plate 8 presses the second spring retaining bead 19, and the second spring retaining bead 19 will be snapped into the inside of the second groove 20.

[0030] The inner wall of the support frame 11 is provided with a second groove 20, and the inner wall of the second groove 20 is provided with a second spring retaining bead 19. The second spring retaining bead 19 is movably engaged with the second groove 20, and the second spring retaining bead 19 will be engaged into the interior of the second groove 20, thereby playing a limiting role for the limiting plate 8.

[0031] Working principle: First, the nut 16 is fitted onto the outer wall of the second thread 15 through the threaded channel. When the nut 16 is rotated, it will move on the second thread 15 through the threaded channel. The downward movement of the nut 16 will cause its threaded groove to fit onto the outside of the installation pipe 2. The threaded groove of the nut 16 will be threadedly connected to the first thread 3, thereby realizing the installation of the transmitter body 4 on the connecting pipe 1.

[0032] Secondly, the second spring retaining bead 19 will be inserted into the interior of the second groove 20, thereby limiting the position of the limiting plate 8. The limiting plate 8 will not automatically change its angle. When the limiting plate 8 is rotated, the second groove 20 will disengage from the second spring retaining bead 19, and the limiting plate 8 can be rotated to a vertical position.

[0033] Finally, one end of the limiting plate 8 will rotate into the inside of the fixing frame 12, and the first spring retaining bead 14 will be inserted into the inside of the first retaining groove 9. Thus, the first spring retaining bead 14 will limit the limiting plate 8, and the limiting plate 8 will fix the distance between the nut 16 and the mounting plate 6, so that the nut 16 will not rotate backward.

[0034] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
