However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0035] Embodiment 1, as Figure 1 - Figure 4 As shown, the utility model provides an anti-detachment wiring structure of a fire protection product, comprising: a housing 1, a circuit board 3 and a power line 10, a first card block 2 is fixedly installed at one end of the housing 1, and further comprising:

[0038] The heat insulation board 8 is fixedly mounted on one end of the power pole 7 close to the through hole 703, and a plurality of threaded rods 801 are rotatably mounted on one end of the heat insulation board 8 away from the power pole 7;

[0039] The pressing plate 803 is threadedly mounted on the outer surfaces of the plurality of threaded rods 801 , and the outer surface of the power connection post 7 is in sliding contact with the inside of the power connection through hole 301 .

[0040] In the present embodiment, when in use, after the staff inserts the wire conductor of the power cord 10 into the through hole 703, they use an external tool such as a plum blossom knife to rotate the control block 701 clockwise, and the rotation of the control block 701 drives the driving gear 702 to rotate clockwise, and the rotation of the driving gear 702 drives the multiple driven gears 802 to rotate, and the rotation of the driven gear 802 drives the threaded rod 801 to rotate in the heat insulation plate 8 and the fixed plate 9. When the multiple threaded rods 801 rotate, the pressing plate 803 moves on the threaded rod 801 and the power connection column 7 toward the heat insulation plate 8, so as to achieve the effect of clamping and fixing the power cord 10 by the pressing plate 803 and the heat insulation plate 8, and the power connection column 7 is in sliding contact with the power connection through hole 301, so as to facilitate the transmission of electric energy to the circuit board 3, and the power cord 10 is between the pressing plate 803 and the heat insulation plate 8, so as to avoid the situation that the core conductor of the power cord 10 directly contacts the circuit board 3, and the high temperature of the local position of the circuit board 3 is caused after the power cord 10 is energized, which is beneficial to protect the circuit board 3 and extend the service life of the circuit board 3.

[0041] Embodiment 2, as Figure 1 - Figure 4As shown, a plurality of threaded rods 801 are fixedly mounted with driven gears 802 at one end away from the heat insulation board 8, and the outer surfaces of the plurality of driven gears 802 are meshedly connected with the driving gears 702. The inner ring of the driving gear 702 is fixedly sleeved with a control block 701. The circuit board 3 is located above the first clamping block 2. A fixing plate 9 is rotatably mounted on one end of the control block 701 away from the driving gear 702. Both ends of the fixing plate 9 away from the control block 701 are rotatably mounted on one end of the plurality of threaded rods 801, and one end of the fixing plate 9 away from the control block 701 is fixedly mounted on one end of the power pole 7. The power supply One end of the wire 10 is in sliding contact with the inner wall of the through hole 703, and multiple hollow tubes 101 are fixedly installed at both ends of the shell 1 away from the first block 2, and buffer rods 5 are slidably installed at one end of the multiple hollow tubes 101 close to the circuit board 3, and elastic parts 102 are fixedly installed at one end of the multiple buffer rods 5 close to the hollow tube 101, and the ends of the multiple elastic parts 102 away from the buffer rod 5 are respectively fixedly installed at one end of the hollow tube 101, and multiple screws 4 are movably installed at one end of the circuit board 3, and the multiple screws 4 pass through one end of the circuit board 3 and are rotatably installed at one end of the multiple buffer rods 5.

[0042] In this embodiment, when in use, when the circuit board 3 is fixed to one end of the buffer rod 5 by the screw 4, the power connection hole 301 and the first clamping block 2 are located on the same axis, and the width of the second clamping block 6 is smaller than the width of the power connection hole 301, so that after the second clamping block 6 is inserted into the first clamping block 2 on the shell 1 through the power connection hole 301, the first clamping block 2 and the second clamping block 6 complete the clamping installation, which is convenient for improving the stability of the second clamping block 6. During the clamping installation of the first clamping block 2 and the second clamping block 6, the circuit board 3 will be squeezed by the second clamping block 6 to move toward the first clamping block 2. When the circuit board 3 moves, it drives the screw 4 and the buffer rod 5 to move. When the buffer rod 5 moves, it slides and contacts with the hollow tube 101, and compresses the elastic member 102 fixed between the buffer rod 5 and the hollow tube 101, which is conducive to reducing the pressure on the circuit board 3 during the installation process, and is conducive to preventing the staff from using excessive force during installation, resulting in excessive pressure on the circuit board 3 and causing damage.

[0043] Working principle: When in use, after the staff inserts the wire conductor of the power cord 10 into the through hole 703, they use an external tool such as a plum blossom knife to rotate the control block 701 clockwise. The rotation of the control block 701 drives the active gear 702 to rotate clockwise. The rotation of the active gear 702 drives multiple driven gears 802 to rotate. The rotation of the driven gear 802 drives the threaded rod 801 to rotate in the heat insulation plate 8 and the fixed plate 9. When the multiple threaded rods 801 rotate, they drive the pressure plate 803 to move on the threaded rod 801 and the power connection column 7 toward the heat insulation plate 8, so as to achieve the effect of clamping and fixing the power cord 10 by the pressure plate 803 and the heat insulation plate 8. The power connection column 7 slides in contact with the power connection through hole 301, so as to transmit electric energy to the circuit board 3. The power cord 10 is between the pressure plate 803 and the heat insulation plate 8, so as to avoid the situation where the power cord 10 is energized and the local position of the circuit board 3 is heated due to the direct contact between the core conductor of the power cord 10 and the circuit board 3, which is beneficial to protect the power cord. The circuit board 3 prolongs the service life of the circuit board 3. When in use, when the circuit board 3 is fixed to one end of the buffer rod 5 by the screw 4, the power connection hole 301 and the first clamping block 2 are located on the same axis, and the width of the second clamping block 6 is smaller than the width of the power connection hole 301, so that after the second clamping block 6 is inserted into the first clamping block 2 on the shell 1 through the power connection hole 301, the first clamping block 2 and the second clamping block 6 complete the clamping installation, which is convenient for improving the stability of the second clamping block 6. During the clamping installation of the first clamping block 2 and the second clamping block 6, the circuit board 3 will be squeezed by the second clamping block 6 to move toward the first clamping block 2. When the circuit board 3 moves, it drives the screw 4 and the buffer rod 5 to move. When the buffer rod 5 moves, it slides and contacts with the hollow tube 101, and compresses the elastic member 102 fixed between the buffer rod 5 and the hollow tube 101, which is conducive to reducing the pressure on the circuit board 3 during the installation process, and is conducive to preventing the circuit board 3 from being damaged due to excessive pressure when the staff uses excessive force during installation.

[0044] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
