DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] To make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the drawings.

[0026] Please refer to Figures 1-3 The present application is a high-precision pressure and temperature dual-parameter transmitter, which comprises:

[0027] The transmitter assembly comprises a shell 11.

[0028] The transmitter assembly further comprises a connecting piece 12 and a base 13. The connecting piece 12 is fixed to the bottom end of the shell 11, and the base 13 is located below the connecting piece 12.

[0029] The shell 11 is used for placing and connecting the internal elements, the connecting piece 12 is used for heat dissipation, and the base 13 is used for connecting the transmitter and the measured container. A temperature-sensitive element is arranged in the probe which moves downward below the base 13, and a pressure-sensitive element is arranged in the shell 11.

[0030] The limiting assembly comprises a fixed frame 22, a spring 23, a clamping block 24 and a magnetic surface 25. The fixed frame 22 is located in the lower periphery of the shell 11, the spring 23 is fixed to the inner two ends of the fixed frame 22, the clamping block 24 is fixed to the opposite end of the spring 23 and is clamped to the two sides of the shell 11, and the magnetic surface 25 is fixed to the opposite end of the two side surfaces of the clamping block 24 and is attracted by the clamping block 24 through the magnetic surface 25.

[0031] The fixed frame 22 is used for connecting the spring 23, the spring 23 is used for connecting and moving the clamping block 24, the clamping block 24 is clamped and limited to the two sides of the shell 11, and the magnetic surface 25 is used for connecting the two clamping blocks 24.

[0032] Support rods 21 are fixedly connected to the bottom ends of the two outer sides of the fixed frame 22. The bottom ends of the support rods 21 are fixed to the two sides of the connection of the container being measured. Friction pads 26 are fixedly connected to the opposite end surfaces of the clamping blocks 24. Slots 27 are opened on the other two sides of the inner side of the fixed frame 22.

[0033] A set of sliders 28 are slidably connected inside the slot 27. A connecting rod 29 is fixedly connected to the opposite ends of the horizontally and vertically adjacent sliders 28. The opposite ends of the connecting rod 29 are fixedly connected to the opposite ends of the clamping block 24 on both sides.

[0034] The support rod 21 is used to fix the connection between the frame 22 and the container under test. The friction pad 26 is used to increase the friction between the clamping block 24 and the housing 11 to prevent relative sliding between the clamping block 24 and the housing 11. The slot 27 is used for the connection and movement of the slider 28. The slider 28 is used for the connection of the connecting rod 29. The connecting rod 29 is used for the connection between the slider 28 and the clamping block 24.

[0035] When the transmitter moves down to connect with the container being measured, the housing 11 is inserted between the inner sides of the clamping block 24. The downward thrust pushes the spring 23 to compress through the clamping block 24, and the clamping block 24 moves through the spring 23. At this time, the clamping block 24 pushes the slider 28 to move in the slot 27 through the connecting rod 29, so that the slot 27 and the slider 28 assist the clamping block 24 to move smoothly.

[0036] Working principle: When the component is not in use, the transmitter is not connected to the container being measured. When the component is in use, the transmitter is pushed down to connect with the container being measured. At this time, the housing 11 is inserted between the inner sides of the clamping blocks 24. The downward thrust pushes the spring 23 through the clamping blocks 24, and the clamping blocks 24 move through the spring 23. At the same time, the clamping blocks 24 push the slider 28 to move in the slot 27 through the connecting rod 29. After the transmitter is connected to the container through the base 13, the clamping blocks 24 are engaged with both sides of the housing 11 through the spring 23, and the clamping blocks 24 are attracted by the magnetic surface 25, so that the clamping blocks 24 connected together limit the two sides of the housing 11. Since the friction pad 26 increases the friction between the clamping blocks 24 and the housing 11, it makes the housing 11 firmly connected to the container through the clamping blocks 24 and the friction pad 26, preventing the transmitter from separating from the container due to loosening at the connection.

[0037] Please see Figure 1 , Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] Downward-pressing component;

[0039] The pressing assembly includes a fixed frame 31, a rotating ring 32, and a crossbar 33; the fixed frame 31 is fixed to both sides of the top of the fixed frame 22, the rotating ring 32 is rotatably connected to the middle section of the transverse surface of the fixed frame 31, and the crossbar 33 is fixed to the inner end of the rotating ring 32.

[0040] The fixed frame 31 is used for the connection and rotation of the rotating ring 32, the rotating ring 32 is used for the connection and rotation of the crossbar 33, and the crossbar 33 is used for the connection of the counterweight 34.

[0043] The counterweight 34 is used for pressing down the shell 11, preventing the shell 11 from being separated from the container, the fixed blocks 35 are used for the connecting grooves 36, and the anti-skid pads 37 are used for increasing the friction between the counterweight 34 and the connecting grooves 36, so as to stably connect the counterweight 34 and the connecting grooves 36 together.

[0044] When the transmitter and the measured container are stably connected together, the counterweight 34 is connected with the connecting grooves 36, so as to stably connect the two together, the counterweight 34 presses down the shell 11, and thus, in cooperation with the clamping block 24, the transmitter is prevented from being separated from the container due to the vibration of the measured container during operation.

[0045] Working principle: when the assembly is not used, the counterweight 34 is located between the inside lower sides of the fixed frame 31, when the assembly is used, the rotating ring 32 is rotated by hand, the rotating ring 32 drives the counterweight 34 to be connected with the connecting grooves 36 through the crossbar 33, so as to drive the anti-skid pads 37 to be connected with the connecting grooves 36, the friction between the counterweight 34 and the connecting grooves 36 is increased due to the anti-skid pads 37, so as to stably connect the counterweight 34 and the connecting grooves 36 together, the counterweight 34 presses down the shell 11 through its own weight, and thus, in cooperation with the clamping block 24, the transmitter is prevented from being separated from the container due to the vibration of the measured container during operation.
