Description

Technical Field

[0001] The utility model relates to the technical field of sensors, and more specifically, to a dual-display temperature control sensor. Background Art

[0002] A temperature sensor refers to a sensor that can sense temperature and convert it into an available output signal. The temperature sensor is the core part of a temperature measuring instrument and comes in a wide variety. It can be divided into two categories: contact type and non-contact type according to the measurement method, and into two categories: thermal resistance and thermocouple according to the sensor material and electronic component characteristics.

[0003] In an existing patent for a temperature sensor, with the patent authorization number CN212779630U, by setting a circuit board, a WIFI module, an intelligent module, and a signal receiver, it is possible to perform remote network query control on the temperature sensor, avoiding the slow detection and query efficiency of the temperature sensor caused by manual wiring control and improving the usage efficiency of the temperature sensor.

[0004] However, in the patent with the authorization number CN212779630U, an operation panel is provided below the display screen. The thermocouple can detect temperature. The sleeve is connected to the body through a card slot, the connecting pipe is rotatably connected to the sleeve, the sleeve enables the connecting pipe to rotate, a thread layer is formed on the connecting pipe, the detection rod is inserted into the connecting pipe, and the thread layer facilitates the connecting pipe to fix the detection body. Since the connection method through threads is prone to loosening, resulting in unstable signal transmission. In order to ensure stable signal transmission, the connection method needs to be changed. Therefore, we propose a dual-display temperature control sensor to solve the above existing problems. Content of the Utility Model

A guide sleeve 4 fixedly connected to the outer wall of the temperature control sensor body 1 is arranged outside the female end joint 2. Guide grooves 5 are symmetrically opened on the inner wall of the guide sleeve 4, and a positioning hole 6 corresponding to the guide groove 5 is opened at the root of the guide sleeve 4;

[0031] Fork arms 7 are symmetrically arranged on the outer wall of the male end joint 3, and a connecting portion fixedly connected to the male end joint 3 is arranged at one end of the fork arm 7 far from the insertion end of the male end joint 3. The connecting portion and the fork arm 7 form an L-shaped structure, and a distance is arranged between the fork arm 7 and the outer wall of the male end joint 3;

[0032] One end of the fork arm 7 away from the connecting part is provided with a clamping joint 8 inside the positioning hole 6, and a bevel surface is arranged at the clamping joint 8;

[0033] It should be noted that when the dual-display temperature control sensor is in use, the fork arm 7 installed outside the male terminal joint 3 is docked with the guide sleeve 4. The bevel surface arranged at the clamping joint 8 abuts against the edge part of the guide groove 5. When the distance between the fork arm 7 and the male terminal joint 3 causes the fork arm 7 to contract inward, the fork arm 7 cooperates with the guide groove 5 to slide. When the clamping joint 8 moves to the root position of the guide sleeve 4, the clamping joint 8 corresponds to the positioning hole 6. The fork arm 7 is reset to make the clamping joint 8 engage with the positioning hole 6, and the male terminal joint 3 and the female terminal joint 2 are completed. Docking, this connection method makes it not easy for the male terminal joint 3 and the female terminal joint 2 to loosen, and can ensure stable signal transmission.

[0034] Such as Figure 4 As shown, a sealing rubber ring 10 is inlaid on the inner wall of the port of the insertion end of the male terminal joint 3, and the sealing rubber ring 10 abuts against the outer wall of the female terminal joint 2;

[0035] It should be noted that by filling the gap between the male terminal joint 3 and the female terminal joint 2 with the sealing rubber ring 10, it can play a very good role in dust prevention and waterproofing, so as to ensure stable and continuous signal transmission.

[0036] Such as Figure 3 、 Figure 4 As shown, the guide groove 5 and the fork arm 7 are in clearance fit, the clamping joint 8 and the positioning hole 6 are in clearance fit, and the horizontal plane of the clamping joint 8 is in contact with the end wall of the positioning hole 6. The connecting part, the fork arm 7 and the clamping joint 8 are integrally formed, and the fork arm 7 is made of elastic PVC material;

[0037] It should be noted that it ensures the guiding accuracy of the guide groove 5 for the fork arm 7, so that the positioning hole 6 and the clamping joint 8 can be accurately docked, and the stability after docking is ensured.

[0038] Such as Figure 1 As shown, a wire 9 is installed at the end of the male terminal joint 3, and the dual-screen display control head 11 is electrically connected to the wire 9;

[0039] It should be noted that the parameters of the temperature control sensor body 1 are displayed through the dual-screen display control head 11.

[0040] During use: By docking the fork arm 7 installed outside the male end joint 3 with the guide sleeve 4, the inclined surface provided at the clamping joint 8 is abutted against the edge part of the guide groove 5. When the distance between the fork arm 7 and the male end joint 3 causes the fork arm 7 to contract inward, the fork arm 7 slides in cooperation with the guide groove 5. When the clamping joint 8 moves to the root position of the guide sleeve 4, the clamping joint 8 corresponds to the positioning hole 6. By resetting the fork arm 7, the clamping joint 8 and the positioning hole 6 are engaged, and the male end joint 3 and the female end joint 2 are completed. Docking, this connection method makes it not easy for the male end joint 3 and the female end joint 2 to loosen.

[0041] The above is only the preferred specific implementation mode of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
