Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a hard flat membrane rod type wireless transmitter. Background Art

[0002] With the continuous development of industrial automation and intelligence, the requirements for the real-time performance, flexibility, and remote monitoring of pressure measurement are becoming increasingly urgent. Due to being restricted by cables, traditional pressure transmitters are difficult to be installed and laid out flexibly, and cannot meet the needs of modern industry for decentralized and mobile measurement points. When measuring some special media, such as high-viscosity, solid-particle-containing, or easily crystallizable fluids, traditional pressure sensors are prone to problems such as blockage and inaccurate measurement. The design of the hard flat membrane aims to solve these problems and provide more reliable and accurate pressure measurement.

[0003] Currently, the main types of transmitters adopt strain gauges, piezoresistive sensors, capacitive sensors, etc. When subjected to pressure, the sensing element will generate corresponding physical changes, such as changes in resistance value, capacitance value, etc., and then transmit the collected signal information for data collection.

[0004] Moreover, there are certain deficiencies in the current transmitters during operation. The angle cannot be adjusted, resulting in the diaphragm not being completely perpendicular to the pressure source, thereby affecting the accuracy and precision of the measurement. And it cannot be telescoped, which limits its application in environments with different depths or limited space. Inside narrow pipes and containers, it may be impossible to reach the appropriate measurement position or it is easily damaged by collision, and at the same time, it brings many inconveniences to installation and maintenance, increasing the installation difficulty, time, and maintenance cost. Content of the Utility Model

[0005] To make up for the above deficiencies, the utility model provides a hard flat membrane rod type wireless transmitter, aiming to improve the problems that the angle and length cannot be adjusted in the prior art.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] The hard flat membrane rod type wireless transmitter includes a rod body. A rotating shaft is rotatably connected to the side wall of the rod body. The other side of the rotating shaft is fixedly connected to a connecting plate. A fixing plate is fixedly connected to the inner wall of the connecting plate. A threaded nut is threadedly connected to the inner wall of the fixing plate. The output end of the threaded nut is rotatably connected to a transition body.

[0009] The rotating shaft and the connecting plate are symmetrically arranged on both sides of the rod body, and the fixing plate is arranged between the two connecting plates;

[0010] The connecting block is fixedly connected to the outer wall of the rod body. A rotating column and a connecting structure are arranged between the connecting block and the transition body for the transition body and the connecting block to form a rotational connection;

[0011] The fixing component includes a side block. The side block is fixedly connected to the rod body. A connecting rotating body is fixedly connected to the inner wall of the side block. A rotating rod is rotatably connected to the outer wall of the connecting rotating body. A clamping block is fixedly connected to the top of the rotating rod. A dial block is fixedly connected to the side wall of the rotating rod;

[0012] A torsion spring is arranged on the outer wall of the connecting rotating body. The connecting rotating body is rotatably connected to the inner wall of the rotating rod through the torsion spring. Both sides of the torsion spring are fixedly connected to the surfaces of the rod body and the rotating rod respectively;

[0013] A compression spring is fixedly connected to the inner wall of the rod body. The other end of the compression spring is fixedly connected to a connecting pad. The bottom of the connecting pad is fixedly connected to the top of the inner rod. A clamping hole is formed in the outer wall of the inner rod;

[0014] The rotating rods are symmetrically arranged on both sides of the rod body. A groove is formed in the outer wall of the rod body, and the opening size of the groove is larger than the size of the clamping block;

[0015] The size of the clamping block is the same as the size of the clamping hole and they cooperate with each other to realize the fixed connection between the rod body and the inner rod.

[0016] The utility model has the following beneficial effects:

[0017] 1. By setting a threaded nut structure to rotate inwardly, the transition body is then pushed forward at the transition body. A rotational connection is formed between the connection structure connected to the transition body and the connection block. Then, the angular offset of the rod body is realized by the forward force of the threaded nut. After adjusting to a suitable angle, it is fixed, which can better adapt to different occasions according to the environment and is more convenient and fast.

[0018] 2. The utility model sets a rotating rod structure.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Reference Figures 1-4 The hard flat membrane rod-type wireless transmitter includes a rod body 1, which provides a stable support and installation position for the hard flat membrane to ensure that the hard flat membrane can accurately sense pressure changes. The side wall of the rod body 1 is rotatably connected with a rotating shaft 10, which is used for the rear side fixing plate 12 and the connecting plate 11 to form a rotatable connection with the rod body 1. The other side of the rotating shaft 10 is fixedly connected with a connecting plate 11, which is used for connecting the rear side fixing plate 12 with the threaded nut 13 structure.

[0028] The inner wall of the connecting plate 11 is fixedly connected with a fixing plate 12. The fixing plate 12 serves to fix and connect the threaded nut 13. The threaded nut 13 can better control the change of the angle of the rod body 1. The inner wall of the fixing plate 12 is threadedly connected with the threaded nut 13. The main control structure for the angle change of the rod body 1 can achieve the angle change of the rod body 1 by the forward movement of the threaded nut 13 itself through its own threaded movement.

[0029] The output end of the threaded nut 13 is rotatably connected with a transition body 14. The transition body 14 can better conduct transition, and the transition body 14 will not rotate due to the rotation of the threaded nut 13. The rear side of the transition body 14 is rotatably connected with a connecting block 15 through a connecting structure. The function of the connecting block 15 is to connect the driving structure (the threaded nut 13) and the rod body 1, and can better control the angle adjustment of the rod body 1.

[0030] The top of the rod body 1 is fixedly connected with a connecting ring 2. The connecting ring 2 connects the rod body 1 with the transmission module 3. The rod body 1 is fixedly connected with the transmission module 3 through the connecting ring 2 to realize the wireless transmission function of signals. The inner wall of the rod body 1 is slidably connected with an inner rod 4. The function of the inner rod 4 is for the pressure and detection structure.

[0031] Sensors are usually arranged at the bottom. The bottom of the inner rod 4 is threadedly connected with a fixing bolt 6 for the fixation and connection of the external structure. The bottom of the fixing bolt 6 is provided with a connection port 7. The function of the connection port 7 is to conduct connection and then achieve the monitoring effect. The side wall of the rod body 1 is provided with a fixing component for the fixation and connection of the inner rod 4.

[0032] The rotating shaft 10 and the connecting plate 11 are symmetrically arranged on both sides of the rod body 1 to achieve the stability of the rod body 1 and prevent tilting on both left and right sides. The fixing plate 12 is arranged between two groups of connecting plates 11. The connecting block 15 is fixedly connected to the outer wall of the rod body 1. There are a rotating column and a connecting structure between the connecting block 15 and the transition body 14 for the transition body 14 and the connecting block 15 to form a rotational connection.

[0033] Refer to Figures 1-5 The fixing component includes a side block 16. The side block 16 serves as a carrier for connecting the rod body 1 with the fixing component. The side block 16 is fixedly connected to the rod body 1. The inner wall of the side block 16 is fixedly connected with a connecting rotating body 20. The function of the connecting rotating body 20 is to connect and rotate the rotating rod 18. The outer wall of the connecting rotating body 20 is rotatably connected with a rotating rod 18 for connecting the top block 19 and the block 17 on the side wall to achieve the rotation effect.

[0034] A clamping block 19 is fixedly connected to the top of the rotating rod 18. The clamping block 19 is clamped with the clamping hole 5 on the outer wall of the inner rod 4 by the rotation of the rotating rod 18 to fix the inner rod 4 relative to the rod body 1. A shifting block 17 is fixedly connected to the side wall of the rotating rod 18 to better rotate the rotating rod 18. A torsion spring 21 is provided on the outer wall of the connecting rotating body 20. The function of the torsion spring 21 is to achieve better pressure supply, so that the rotating rod 18 in a stationary state can be squeezed by the torsion spring 21 and fit with the rod body 1.

[0035] The connecting rotating body 20 is rotatably connected to the inner wall of the rotating rod 18 through a torsion spring 21. The two sides of the torsion spring 21 are fixedly connected to the surface of the rod body 1 and the rotating rod 18 respectively. The inner wall of the rod body 1 is fixedly connected with a compression spring 9. The function of the compression spring 9 is to better apply force when the inner rod 4 is fixed so that the inner rod 4 can achieve the effect of being stable and not shaking.

[0036] The other end of the compression spring 9 is fixedly connected to a connecting pad 8, which is used to connect to the inner rod 4. The bottom of the connecting pad 8 is fixedly connected to the top of the inner rod 4. A clamping hole 5 is opened on the outer wall of the inner rod 4, which cooperates with the clamping block 19 to fix the inner rod 4.

[0037] Reference Figures 1-5 The rotating rod 18 is symmetrically arranged on both sides of the rod body 1, and a groove is opened on the outer wall of the rod body 1 to ensure that the block 19 can contact the clamping hole 5 to realize the fixed connection of the inner rod 4, and the opening size of the groove is larger than the size of the block 19. The size of the block 19 is the same as the size of the clamping hole 5 and they cooperate with each other to realize the fixed connection between the rod body 1 and the inner rod 4, which is used for the fixed connection of the inner rod 4.

[0038] Working principle: First, the length of the hard flat film rod type wireless transmitter is adjusted according to the environment and the measurement points at different depths and spaces. By turning the dial block 17, the rotating rod 18 will rotate through the action of the connecting rotating body 20. The rotation of the rotating rod 18 drives the clamping block 19 to disengage from the clamping hole 5 on the outer wall of the inner rod 4. Then, the compression spring 9 and the connecting pad 8 will change the position of the inner rod 4.

[0039] Then, after manually pulling or compressing the inner rod 4 to a suitable position as required, the shifting block 17 is released. Because a torsion spring 21 is provided at the connection between the rotating rod 18 and the connecting rotating body 20, the rotating rod 18 will bring the clamping block 19 back to the initial position through the action of the torsion spring 21 to connect and fix the clamping hole 5 on the inner rod 4 at this time, thereby fixing the inner rod 4.

[0040] Adjust the angle of the rod body 1 according to the angle change of the pipeline to ensure that it is completely perpendicular to the pressure source. By rotating the threaded nut 13, the threaded nut 13 will move inward, and then the angle of the rod body 1 will be offset according to the action of the threaded nut 13. After adjusting to the appropriate angle, stop the rotation of the threaded nut 13, and then connect the rod body 1 to the outside through the connection port 7 for subsequent work requirements.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or equivalently replace some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
