Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, and in particular to a detachable temperature sensor. Background Technology

[0002] In industrial production and equipment maintenance, temperature sensors are key components for monitoring equipment operating status. They need to be installed on the surface or inside of equipment such as pipes, reactors, and robotic arms for a long time to provide real-time temperature data to ensure the normal operation of the equipment.

[0003] However, traditional temperature sensors employ a fixed structure, connecting to equipment via welding or an integrated housing. When a sensor malfunctions and requires repair or replacement, the entire mounting structure must be disassembled or the equipment surface damaged. This is not only cumbersome and time-consuming but also prone to causing secondary damage to the equipment during disassembly. Especially in high-precision equipment or continuous production scenarios, frequent disassembly and maintenance can severely impact production efficiency, making it difficult to meet the needs for rapid repair and flexible replacement. Therefore, we have introduced a detachable temperature sensor. Utility Model Content

[0004] The main objective of this invention is to provide a detachable temperature sensor that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A detachable temperature sensor includes a fixing plate, with four through-holes at the front corners of the fixing plate. An installation component is fixedly connected to the middle of the front of the fixing plate. A connecting plate is fixedly connected to the front of the installation component. A fixing device is fixedly connected to the front of the connecting plate. The connecting component is movably installed inside the fixing device.

[0007] Preferably, the fixing device includes two arc-shaped plates, which are symmetrically distributed from left to right. Two support rods are fixedly connected to the rear of the outer surface of each of the two arc-shaped plates. A left clamping assembly is inserted through the outer surface of the left arc-shaped plate, and a right clamping assembly is inserted through the outer surface of the right arc-shaped plate. The left and right clamping assemblies have the same structure and are symmetrically distributed from left to right. The rear ends of the four support rods are fixedly connected to the front end of the connecting plate.

[0008] By adopting the above technical solution: two symmetrical arc-shaped plates provide a space for the connecting components, the support rod realizes a stable connection between the arc-shaped plates and the connecting plates, and the left and right symmetrical clamping components can clamp the connecting components simultaneously from both sides.

[0009] Preferably, the left clamping assembly includes a screw and an arc-shaped clamping plate. A return spring is fixedly connected to the middle of the outer surface of the arc-shaped clamping plate, and the left end of the return spring is fixedly connected to the inner wall of the left arc-shaped plate. Balance guide rods are fixedly connected to both the front and rear of the outer surface of the arc-shaped clamping plate, and the right ends of the two balance guide rods are movably connected to the inner wall of the left arc-shaped plate. A rubber pad is fixedly connected to the inner wall of the arc-shaped clamping plate, and a limit block is fixedly connected to the lower part of the inner wall of the rubber pad. The right end of the screw is threadedly connected to the outer surface of the left arc-shaped plate.

[0010] By adopting the above technical solution: rotating the screw can push the arc-shaped clamping plate to clamp the connecting component; the rubber pad prevents damage to the connecting component during clamping; the limit block plays a positioning role for the connecting component; the reset spring facilitates the automatic reset of the arc-shaped clamping plate when the screw is released; and the balance guide rod ensures that the arc-shaped clamping plate moves smoothly and prevents it from tilting.

[0011] Preferably, the outer surface of the arc-shaped clamping plate has a guide hole, and the right side of the screw is movably sleeved in the guide hole;

[0012] The screw is located inside the return spring and there is a gap between it and the inner wall of the return spring.

[0013] By adopting the above technical solution, the screw is located inside the return spring and does not contact the inner wall of the return spring, which can prevent the return spring from being worn when the screw rotates and extend the service life of the return spring.

[0014] Preferably, the mounting assembly includes a mounting plate, a first retaining plate, and bolts. The mounting plate has a first retaining groove at its upper end and a second retaining groove that passes through the first retaining groove at the middle of its front end. The mounting plate also has first screw holes that pass through the first retaining groove at its left and right front ends. A second retaining plate is fixedly connected to the middle of the front end of the first retaining plate, and the first retaining plate also has second screw holes at its left and right front ends. The rear end of the mounting plate is fixedly connected to the front end of the fixing plate.

[0015] Preferably, the first card plate is movably engaged in the first card slot, and the second card plate is movably engaged in the second card slot;

[0016] The outer surfaces of the two bolts are respectively threaded into the corresponding first threaded holes and extend into the corresponding second threaded holes;

[0017] The front end of the second card plate is fixedly connected to the rear end of the connecting plate.

[0018] By adopting the above technical solution, the snap-fit ​​between the first card plate and the first card slot, and the second card plate and the second card slot, ensures the accuracy of the connection between the installation component and the connecting plate. The threaded connection of the bolts further enhances the stability of the connection between the two. At the same time, the installation component and the connecting plate can be separated by removing the bolts, realizing the convenient disassembly of the overall structure and facilitating maintenance.

[0019] Preferably, the connecting assembly includes a fixing cap, in which a temperature sensor body is fixedly sleeved, and a dial is fixedly installed on the upper end of the temperature sensor body.

[0020] By adopting the above technical solution: the temperature sensor body is selected as "PT100 platinum resistance temperature sensor (model: WZP-230)" and the dial is selected as "pointer type temperature dial (model: YXC-100)".

[0021] Preferably, the fixing cap is located inside the rubber pad and at the upper end of the limiting block.

[0022] By adopting the above technical solution, the rubber pad wraps around the outer surface of the fixing cap, which on the one hand avoids hard squeezing damage to the fixing cap when the fixing device clamps it, and on the other hand enhances the connection stability between the fixing cap and the clamping structure through the friction of the rubber, preventing the fixing cap from sliding. The limiting block provides bottom support and positioning for the fixing cap, ensuring that the fixing cap is in a central and stable position within the fixing device, avoiding the temperature sensor body from being affected by the offset of the fixing cap, and at the same time simplifying the installation and alignment operation of the fixing cap and improving assembly efficiency.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] In this invention, the first and second clamping plates of the mounting component cooperate with the first and second clamping slots, and together with the fixing effect of bolts, it can ensure the connection stability between the mounting component and the fixing plate, and also allow for quick separation of the mounting component and its upper structure by removing the bolts, facilitating overall maintenance. The left and right clamping components of the fixing device push the arc-shaped clamping plate through the screw, and together with the rubber pad and the limit block, achieve a stable clamping of the connecting component. The return spring and the balance guide rod ensure a smooth clamping process and automatic reset, facilitating quick disassembly and replacement of the connecting component. The whole device realizes the detachable function of the temperature sensor body from part to whole, which is convenient to operate, effectively reduces the time and cost of maintenance and replacement, avoids damage to the equipment, and improves the maintenance efficiency and usage flexibility of the temperature sensor.
