DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] In order to facilitate the replacement and installation of the probe rod, etc., and at the same time protect the compression spring including the transmission wire arranged inside, as an embodiment of the utility model, Figure 1-Figure 4 As shown, a high-temperature resistant temperature sensor described in the utility model includes a heat-insulating protective layer 5, the top of the heat-insulating protective layer 5 is fixedly connected to the bottom of a connecting block 4, a mounting groove 9 and a clamping groove 3 are provided inside the connecting block 4, the mounting groove 9 is communicated with the inside of the clamping groove 3, the connecting block 4 is inserted at the bottom end of a threaded rod 2, a slot 10 is provided at the bottom end of the threaded rod 2, and movable chambers 13 are provided on both side inner walls of the slot 10, a torsion spring 11 is installed inside the threaded rod 2, one end of the torsion spring 11 is fixedly connected to one end of a clamping block 12, and the clamping block 12 is movably arranged in the slot 10 and the movable chamber 13.

[0025] During use, when the probe rod 8 needs to be installed, first slide the connecting block 4 horizontally into the slot 10 of the threaded rod 2. During the sliding process, the connecting block 4 will push the clamping block 12 to rotate along the central axis of the torsion spring 11. As the connecting block 4 slides until the other end of the clamping block 12 is away from the torsion spring 11, it can be put into a part of the installation groove 9. Release the sliding of the connecting block 4, and the torsion spring 11 will drive the clamping block 12 to rebound to its original position, so that the connecting block 4 is completely covered on the outside of the clamping block 12. Then, pull the connecting block 4 down for a distance so that the clamping block 12 can be stuck in the clamping slot 3, so that the clamping block 12 is in full contact with the connecting block 4.

[0026] For example, Figure 1-4 As shown, the new use also includes that the installation groove 9 is used for the card block 12 to be installed and placed inside, the card groove 3 is used for the card block 12 to be installed by clamping, and the top of the threaded rod 2 is fixedly connected with the connection line 1.

[0027] When in use, the connecting line 1 is electrically connected to the card block 12. Both the card block 12 and the connecting block 4 are made of copper, which can achieve heat resistance and electrical connection. The volume of the connecting block 4 is smaller than the volume of the slot 10, which facilitates the movement of the card block 12.

[0028] For example, Figure 1-4 As shown, the new use also includes that the inner top center of the thermal insulation protective layer 5 is fixedly connected to the top of the compression spring 16, the bottom end of the compression spring 16 is fixedly connected to the top of the compression fixing ring 14, the inner top of the thermal insulation protective layer 5 is fixedly connected to the top of the connecting column 15, the inner bottom end of the thermal insulation protective layer 5 is fixedly connected to the bottom end of the connecting column 15, and the connecting column 15 is provided with a plurality of them, and the compression fixing ring 14 is sleeved on the outer side of the plurality of connecting columns 15.

[0029] When in use, the clamping and fixing ring 14 can be raised around the connecting column 15, and the rotating ball 7 can be freely rotated by moving the probe rod 8, thereby driving the probe rod 8 to adjust the angle, and then the lifting of the clamping and fixing ring 14 can be released, allowing the clamping spring 16 to drive the clamping and fixing ring 14 to press down on the top of the rotating ball 7, thereby fixing the rotating ball 7 and fixing the probe rod 8.

[0030] For example, Figure 1-4 As shown, the new use also includes that a rotating ball 7 is movably installed at the bottom end of the thermal insulation protective layer 5, the bottom end of the rotating ball 7 is fixedly connected to the top end of the probe rod 8, the top end of the rotating ball 7 is fixedly connected to one end of the transmission line 17, the other end of the transmission line 17 passes through the clamping fixing ring 14 and the inner top end of the thermal insulation protective layer 5 and is fixedly connected to the bottom end of the connecting block 4, and the transmission line 17 is arranged inside the clamping spring 16.

[0031] When in use, the transmission line 17 is electrically connected to the connection block 4 . After the point connection block 4 is connected and in contact with the card block 12 , the transmission line 17 can be electrically connected to the connection line 1 through the connection between the connection block 4 and the card block 12 .

[0032] For example, Figure 1-4 As shown, the present invention also includes that a movable door 6 is movably installed on one side of the heat-insulating protective layer 5, and a placement groove 18 is provided inside one side of the heat-insulating protective layer 5, and the placement groove 18 is used for the movable door 6 to be inserted and placed.

[0033] When in use, the movable door 6 on the outer side of the heat-insulating protective layer 5 can be pushed upward into the placement groove 18 to facilitate lifting the internal compression fixing ring 14 .

[0034] When the utility model is in use, when the probe rod 8 needs to be installed, the connecting block 4 is first slid horizontally into the slot 10 of the threaded rod 2. During the sliding process, the connecting block 4 will push the clamping block 12 to rotate along the central axis of the torsion spring 11. As the connecting block 4 slides until the clamping block 12 is away from the other end of the torsion spring 11, a part of the installation groove 9 can be put into the installation groove 9. The sliding of the connecting block 4 is released, and the torsion spring 11 will drive the clamping block 12 to rebound to its original position. In this way, the connecting block 4 is completely sheathed on the outside of the clamping block 12. Then, the connecting block 4 is pulled down for a distance so that the clamping block 12 can be clamped in the clamping groove 3, so that the clamping block 12 and the clamping block 12 can be clamped in the clamping groove 3. The connecting block 4 is in full contact, and with the connection between the card block 12 and the connecting block 4, the connecting line 1 can be connected to the transmission line 17, and the movable door 6 on the outside of the thermal insulation protective layer 5 can be pushed upward into the placement groove 18. The clamping and fixing ring 14 can be raised around the connecting column 15, and the rotating ball 7 can be freely rotated by moving the probe rod 8, thereby driving the probe rod 8 to adjust the angle, and then release the lifting of the clamping and fixing ring 14, allowing the clamping spring 16 to drive the clamping and fixing ring 14 to press down on the top of the rotating ball 7, fix the rotating ball 7, and then fix the probe rod 8.

[0035] When the probe rod 8 needs to be disassembled, it is only necessary to push the connecting block 4 upward by one end to allow the card block 12 to disengage from the card slot 3 and place it in the installation slot 9, and then continue to push the connecting block 4 in the direction of installation. The card block 12 will be pushed by the connecting block 4 and rotate along the central axis of the torsion spring 11, so that the card block 12 will gradually disengage from the installation slot 9 until the connecting block 4 can slide out of the slot 10.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
