Description

Technical Field

[0001] This utility model belongs to the field of transmitter technology, and specifically relates to a transmitter with protective function. Background Technology

[0002] A transmitter is an industrial automation instrument that converts physical quantities (such as temperature, pressure, flow rate, liquid level, etc.) into standard electrical signals (such as 4-20mA, 0-10V, HART protocol, Profibus, etc.). It is widely used in industrial process control, environmental monitoring, energy management and other fields, and is one of the core components of automation systems. However, when using a transmitter, a protective mechanism is required to protect it.

[0003] Existing transmitters with protective functions are assembled by welding support rods of different lengths into a single protective frame. The transmitter to be installed is then bolted to the protective frame, ensuring stable installation. The transmitter is then connected to an external piping system for use. However, in actual use, due to different requirements and installation positions on the piping system, multiple transmitters are needed for each system. This necessitates welding multiple different protective frames, which is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a transmitter with a protective function. The transmitter body is stably protected by a retractable protective frame, which also allows for quick adjustment of the installation height of the transmitter body, making it convenient and easy to use.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a transmitter with protective function, including a transmitter body, a protective module detachably installed on the rear side of the transmitter body, the protective module including a protective base frame, a sliding frame slidably arranged on the upper side of the protective base frame, a protective top frame slidably arranged on the upper side of the sliding frame, a driving mechanism provided between the protective top frame, the sliding frame and the protective base frame, the driving mechanism being used to drive the movement between the protective top frame, the sliding frame and the protective base frame; a fixed seat is welded and fixed on the protective top frame, and the front side of the fixed seat is detachably installed to the transmitter body by bolts.

[0006] As a further improvement of this utility model, the drive mechanism includes a driven seat disposed on the rear side of the protective top frame and the protective bottom frame. Each driven seat has symmetrically distributed driven blocks slidably disposed inside. A drive seat is disposed in the middle of the sliding frame. A drive block is slidably disposed inside the drive seat. A symmetrically distributed connecting rod 1 is rotatably disposed on the drive block on the left side. A symmetrically distributed connecting rod 2 is rotatably disposed on the drive block on the right side. The ends of connecting rod 1 and connecting rod 2 away from the drive block are respectively rotatably connected to the adjacent driven blocks. The middle of connecting rod 1 and the middle of the adjacent connecting rod 2 are rotatably connected.

[0007] As a further improvement of this utility model, a bidirectional lead screw is rotatably provided inside the drive base, and both drive blocks are threadedly connected to the bidirectional lead screw; a handwheel is provided at the end of the bidirectional lead screw.

[0008] As a further improvement of this utility model, the bottom end of the protective base is provided with multiple mounting plates, each of which has mounting holes; rubber pads are glued and fixed to the lower surface of each mounting plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, a retractable protective frame can be formed by the combination of the protective top frame, sliding frame, and protective base frame. The protective frame provides stable protection for the transmitter body, while the retractable protective frame allows for quick adjustment of the transmitter body's installation height, making it convenient and easy to use.

[0011] Secondly, the rotation of the bidirectional screw drives the driven seats on both sides to move towards each other or away from each other, which in turn drives the protective base frame and the protective top frame to move towards each other or away from each other. This causes the protective top frame to raise or lower the transmitter body, adjusting the installation height of the transmitter body and facilitating its subsequent installation on the pipe assembly.

[0012] Thirdly, the threaded relationship between the bidirectional lead screw and the drive block drives the drive blocks on both sides to move towards each other or away from each other. During the movement of the drive block, the drive block rotates with the adjacent connecting rod one or connecting rod two, and the driven block rotates with the adjacent connecting rod one or connecting rod two. Since the drive block, connecting rod one, connecting rod two and the driven block can form a scissor brace structure, the installation height of the transmitter body can be stably adjusted.

[0013] Fourth, the rubber pads that are glued to the underside of the mounting plate prevent damage to the mounting plate caused by excessive tightening of the bolts during installation. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 2 As shown, the transmitter includes a transmitter body 105. A protective module is detachably mounted on the rear side of the transmitter body 105. The protective module includes a protective base frame 101. A sliding frame 102 is slidably mounted on the upper side of the protective base frame 101. A protective top frame 103 is slidably mounted on the upper side of the sliding frame 102. A driving mechanism is provided between the protective top frame 103, the sliding frame 102, and the protective base frame 101. The driving mechanism is used to drive the movement between the protective top frame 103, the sliding frame 102, and the protective base frame 101. A fixing seat 104 is welded and fixed on the protective top frame 103. The front side of the fixing seat 104 is detachably mounted to the transmitter body 105 by bolts. The transmitter body 105 can be a 3051S CD2A model.

[0022] like Figure 3 , 4As shown, the drive mechanism includes a driven seat 203 disposed on the rear side of the protective top frame 103 and the protective bottom frame 101. Each driven seat 203 has symmetrically distributed driven blocks 204 slidably disposed inside. A drive seat 201 is disposed in the middle of the sliding frame 102. A drive block 202 is slidably disposed inside the drive seat 201. A symmetrically distributed connecting rod 205 is rotatably disposed on the left drive block 202, and a symmetrically distributed connecting rod 206 is rotatably disposed on the right drive block 202. The ends of the connecting rods 205 and 206 away from the drive block 202 are respectively rotatably connected to the adjacent driven blocks 204. The middle of the connecting rod 205 and the adjacent connecting rod 206 are rotatably connected. A double-acting screw 207 is rotatably disposed inside the drive seat 201. Both drive blocks 202 are threadedly connected to the double-acting screw 207. A handwheel 208 is disposed at the end of the double-acting screw 207.

[0023] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the bottom of the protective base frame 101 is provided with multiple mounting plates 106, each of which has mounting holes; rubber pads are glued and fixed to the lower surface of each mounting plate 106.

[0024] In use, the transmitter body 105 is fixed to the mounting base 104 with bolts, and the transmitter body 105 is fixed to the protective top frame 103.

[0025] Then, rotating the handwheel 208 causes the connected bidirectional lead screw 207 to rotate. This, in turn, through the threaded relationship between the bidirectional lead screw 207 and the drive block 202, causes the drive blocks 202 on both sides to move towards each other or away from each other. During the movement of the drive blocks 202: the drive blocks 202 rotate with adjacent connecting rod 1 205 or connecting rod 206 respectively; the driven block 204 rotates with adjacent connecting rod 1 205 or connecting rod 206 respectively. Since the drive blocks 202, connecting rod 1 205, connecting rod 206, and driven block 204 can form a scissor brace structure, the rotation of the bidirectional lead screw 207 drives... The driven seats 203 on the upper and lower sides move towards each other or away from each other, thereby causing the protective base frame 101 and the protective top frame 103 to move towards each other or away from each other. This causes the protective top frame 103 to raise or lower the transmitter body 105, adjusting the installation height of the transmitter body 105, which facilitates subsequent installation on the pipe assembly. The protective top frame 103, the sliding frame 102, and the protective base frame 101 can cooperate to form a telescopic protective frame. The protective frame provides stable protection for the transmitter body 105, and the telescopic protective frame allows for quick adjustment of the installation height of the transmitter body 105, making it convenient and easy to use.

[0026] Then, the mounting plate 106 is fixed to the ground by tightening the bolts with external tools. The rubber pads on the lower surface of the mounting plate 106 are used to prevent the bolts from being tightened too much during installation, which could cause damage to the mounting plate 106.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
