Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 A temperature transmitter with an overheat protection structure is shown, comprising a protective housing 1. A temperature sensor 2, a support frame 3, and a support block 4 are fixedly connected to the bottom plate of the protective housing 1. A vertically extending groove 5 is fixedly connected to the side wall of the protective housing 1 near the support block 4. A slider 6 is slidably connected within the groove 5. The slider 6 is fixedly connected to the temperature transmitter body 7. A heat-conducting plate 8 is fixedly connected to the temperature transmitter body 7, and heat dissipation fins 9 are fixedly connected to the heat-conducting plate 8. A cooling fan 10 is fixedly connected to the inner wall of the protective housing 1 on the side opposite to the groove 5. The cooling fan 10 has an opening in the housing of the protective housing 1, and a step 11 is provided at the opening. A dustproof plate 12 is detachably connected to the step 11. A first dustproof net 13 is connected inside the dustproof plate 12, and a pull hook 14 is fixedly connected to the dustproof plate 12. Hook 14 facilitates the removal of dustproof plate 12 for cleaning of first dustproof net 13; a window is provided on the protective shell 1 below the dustproof plate 12, and a wire fixing device 15 is fixedly connected to the window. The connecting wire of the temperature transmitter body 7 extends out of the window and is fixed by the wire fixing device 15. The wire fixing device 15 includes a mounting plate 16, which is fixedly connected to the protective shell 1. The mounting plate 16 has symmetrically provided limit grooves 17, and a connecting rod 18 is slidably connected in the limit grooves 17. The connecting rod 18 is fixedly connected to the upper plate 19, and the upper plate 19 is slidably connected to the mounting plate 16; a cover plate 20 is detachably slidably connected to the top of the protective shell 1. A handle 21 is fixedly connected to the cover plate 20, and a connector 22 is fixedly connected to the handle 21. The connector 22 is detachably connected to the protective shell 1 by bolts.

[0022] The temperature sensor 2 is electrically connected to the switch of the temperature transmitter body 7. When the internal temperature of the protective housing 1 is too high and reaches the set value, the temperature sensor 2 sends a signal to the temperature transmitter body 7 to shut it down, preventing damage to the temperature transmitter body 7 due to high operating temperature.

[0023] The main body of the support frame 3 is L-shaped, with limiting plates fixedly connected to both sides. The thickness of the side of the main body of the support frame 3 that contacts the protective shell 1 is the same as that of the support block 4. The temperature transmitter body 7 is detachably connected to the main body of the support frame 3 and the support block 4, and the two sides of the temperature transmitter body 7 are slidably connected to the limiting plates on both sides of the support frame 3. The support frame 3 and the slide groove 5 are used to limit the temperature transmitter body 7 in the horizontal direction. The above structure makes the contact area between the temperature transmitter body 7 and the protective shell 1 small, preventing the temperature transmitter body 7 from accumulating heat.

[0024] An opening is provided above the slide 5 on the protective shell 1, and a second dustproof net 23 is fixedly connected to the opening. The air outlet of the cooling fan 10 points to the second dustproof net 23.

[0025] A magnet is fixedly connected to the step 11, and the dustproof plate 12 is made of magnetic material. The dustproof plate 12 and the protective shell 1 are magnetically connected at the step 11.

[0026] Each of the two side walls of the protective shell 1 is detachably connected to a limiting member 24 by bolts. The limiting member 24 is L-shaped, and one side of the limiting member 24 abuts against the heat dissipation fins 9. The two limiting members 24 are used to limit the temperature transmitter body 7 in the vertical direction.

[0027] A wire-passing hole 25 is provided between the upper plate 19 and the mounting plate 16. The wire-passing hole 25 is used to fix the connecting wire of the temperature transmitter body 7. A stop block 26 is fixedly connected to the upper end of the limiting groove 17 on the mounting plate 16. A limiting block 27 is fixedly connected to the bottom of the connecting rod 18. The stop block 26 and the limiting block 27 cooperate to prevent the connecting rod 18 from falling out of the groove. The limiting block 27 is slidably connected to the limiting groove 17.

[0028] A spring 28 is sleeved on the connecting rod 18. The spring 28 is located between the limiting block 27 and the stop block 26. When the upper plate 19 is pulled upward, the spring 28 contracts. When the hand is released, the upper plate 19 moves towards the mounting plate 16 due to the elastic force of the spring 28, so that the upper plate 19 and the mounting plate 16 are merged.

[0029] The upper plate 19 and the handle 21 have arc-shaped openings on both sides, which facilitates the application of force by fingers.

[0030] During installation, insert the slider 6 on the temperature transmitter body 7 downward along the slide groove 5 until it reaches the support block 4. Then, install the two limiting pieces 24 onto the protective shell 1 to fix the temperature transmitter body 7 inside the protective shell 1. Pull the upper closing plate 19 upward to extend the connecting wire of the temperature transmitter body 7 outward from the window. Release the pull, and the upper closing plate 19 will automatically close downward. Finally, close the cover plate 20 and fix the cover plate 20 to the protective shell 1 with the bolts at the connector 22.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
