Description

Technical Field

[0001] This utility model relates to the field of temperature measurement technology, and more specifically, to a thermocouple that is easy to connect quickly. Background Technology

[0002] Thermocouples are one of the temperature sensors used in industrial production and scientific experiments. Based on the Seebeck effect, they convert temperature signals into thermoelectric potential signals. They have advantages such as wide temperature measurement range, simple structure, and fast dynamic response. They are widely used in temperature monitoring and control in metallurgy, chemical industry, power, aerospace and other fields. In actual use, thermocouples usually need to be fixedly connected to the measured equipment or mounting base through a connection structure so that the temperature measuring end can be accurately placed at the temperature measuring point.

[0003] Existing thermocouple connection methods mainly include threaded connection and flange connection. Threaded connection requires repeated turning many times, which is time-consuming to assemble and disassemble, and is particularly inconvenient for frequent replacement or operation in confined spaces. Flange connection is bulky and complicated, making it difficult to apply in restricted space scenarios. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore: The first aspect of this utility model proposes a thermocouple that is easy to connect quickly, including a base, a measuring component, and a connecting component. The outer wall of the base has an abutment groove, and the inner side wall of the abutment groove has an engagement groove. The measuring component is disposed on the base. The connecting component includes a limiting plate, a pressing block, an engagement block, an abutment block, and several return springs. The limiting plate is fixed to the outer wall of the measuring component. The pressing block is fixed to one end of the limiting plate near the base. The engagement block is fixed to the pressing block and engages with the engagement groove. The abutment block is slidably connected to the base. The return springs are disposed between the abutment block and the base. When the pressing block is located in the abutment groove, the abutment block is in a first position, forming a stop on the side of the pressing block away from the engagement groove. When the abutment block is in a second position, the pressing block can disengage from the abutment groove.

[0006] This invention proposes a thermocouple for easy and quick connection. During installation, the measuring component is aligned with the base and inserted, so that the lower pressure block aligns with and abuts against the abutment block. As the measuring component continues to be inserted, the lower pressure block gradually pushes the abutment block from the first position to the second position, while simultaneously compressing the return spring. When the limiting plate is in contact with the end face of the base, the limiting plate is rotated, causing the lower pressure block to rotate synchronously and disengage from the abutment block, then move into the abutment groove. At this time, the locking block fixed to the lower pressure block engages with the locking groove, and the locking block engages with the abutment groove. The groove fits together to fix the measuring component axially. At the same time, the abutment block is pushed back to the first position by the return spring due to the removal of the lower pressure block, forming a stop on the side of the lower pressure block away from the locking groove, preventing the lower pressure block from rotating, and thus preventing the locking block from disengaging from the locking groove, thereby achieving circumferential fixation of the measuring component. During disassembly, push the abutment block to the second position to release the stop on the lower pressure block, and then rotate the limit plate in the opposite direction. The lower pressure block will drive the locking block to disengage from the locking groove, and then the measuring component can be pulled out to achieve quick disassembly.

[0007] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0011] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0012] Please see Figures 1 to 4 A thermocouple for easy and quick connection is provided, comprising a base 100, a measuring component 200, and a connecting component 300. The outer wall of the base 100 has an abutment groove 390, and the inner wall of the abutment groove 390 has an engagement groove 340. The measuring component 200 is disposed on the base 100. The connecting component 300 includes a limiting plate 310, a pressing block 320, an engagement block 330, an abutment block 350, and several return springs 360. The limiting plate 310 is fixed to the outer wall of the measuring component 200; the pressing block 320 is fixed to the limiting plate 310. 0 is located near the end of the base 100; the engaging block 330 is fixed to the lower pressing block 320, and the engaging block 330 is engaged and fixed with the engaging groove 340; the abutment block 350 is slidably connected to the base 100; the return spring 360 is disposed between the abutment block 350 and the base 100; wherein, when the lower pressing block 320 is located in the abutment groove 390, the abutment block 350 is in the first position, forming a stop on the side of the lower pressing block 320 away from the engaging groove 340; when the abutment block 350 is in the second position, the lower pressing block 320 can disengage from the abutment groove 390.

[0013] In this embodiment: The outer wall of the base 100 is provided with an abutment groove 390, and the inner side wall of the abutment groove 390 is provided with a locking groove 340; the abutment groove 390 is used to accommodate the lower pressure block 320 and provide space for its circumferential rotation, and the locking groove 340 is used to cooperate with the locking block 330 to achieve axial locking.

[0014] The measuring component 200 is disposed on the base 100; the measuring component 200 is used to acquire and output the temperature signal of the object being measured.

[0015] The limiting plate 310 is fixed to the outer wall of the measuring component 200; the limiting plate 310 moves synchronously with the measuring component 200 to limit the depth of the measuring component 200 inserted into the base 100.

[0016] The pressing block 320 is fixed to one end of the limiting plate 310 near the base 100; the pressing block 320 is inserted and rotated synchronously with the limiting plate 310, pushing the abutment block 350 to move during insertion, and driving the locking block 330 to enter or exit the locking groove 340 during rotation.

[0017] The locking block 330 is fixed to the lower pressure block 320, and the locking block 330 is locked in place with the locking groove 340. The locking block 330 is locked into or disengaged from the locking groove 340 as the lower pressure block 320 rotates. The locking engagement restricts the axial displacement of the measuring component 200 relative to the base 100, preventing the measuring component 200 from coming out of the base 100.

[0018] The abutment block 350 is slidably connected to the base 100; the abutment block 350 can slide along the axial direction of the base 100 between a first position and a second position. In the first position, it forms a circumferential stop on the lower pressure block 320 to prevent the lower pressure block 320 from rotating and loosening. In the second position, the stop is released, allowing the lower pressure block 320 to rotate freely to complete the disassembly.

[0019] A return spring 360 is disposed between the abutment block 350 and the base 100. When the pressing block 320 is located in the abutment groove 390, the abutment block 350 is in the first position, forming a stop on the side of the pressing block 320 away from the engaging groove 340. When the abutment block 350 is in the second position, the pressing block 320 can disengage from the abutment groove 390. The return spring 360 provides elastic return force to the abutment block 350. When the abutment block 350 is pushed to the second position by the pressing block 320, the return spring 360 is compressed and stores energy. After the pressing block 320 rotates away from the abutment block 350, the return spring 360 releases elastic potential energy, driving the abutment block 350 to return to the first position, thereby realizing automatic stop locking of the pressing block 320.

[0020] Please see Figure 1 In some embodiments of this utility model, the measuring component 200 includes a connector 210, a thermocouple 220, and a flexible cable 230.

[0022] One end of the thermocouple 220 is fixed to the connector 210, and the other end extends to the outside of the connector 210; the end of the thermocouple 220 extending to the outside of the connector 210 is used to contact the object being measured to sense the temperature and transmit the generated electrical signal to the flexible cable 230.

[0023] One end of the flexible cable 230 is connected to the end of the connector 210 away from the thermocouple 220; the flexible cable 230 is used to transmit the electrical signal generated by the thermocouple 220 to an external display or control device, and its flexible structure facilitates wiring in different installation scenarios.

One end of the T-shaped block 370 is fixed to the abutment block 350, and the other end of the T-shaped block 370 is slidably engaged with the T-shaped groove 380.

[0025] In this embodiment: The outer wall of the base 100 is provided with a T-slot 380; the T-slot 380 provides a sliding guide track for the T-block 370, and at the same time restricts the displacement of the T-block 370 in the direction perpendicular to the sliding direction through the structure of the T-section.

[0026] One end of the T-block 370 is fixed to the abutment block 350, and the other end of the T-block 370 is slidably fitted into the T-groove 380. The fit between the T-block 370 and the T-groove 380 allows the abutment block 350 to slide back and forth along the axial direction of the base 100, preventing the abutment block 350 from swaying or falling off during the sliding process.
