In this embodiment, the heat dissipation mechanism includes vent 10 and the spacing groove 8 of seting up in the lateral wall of heat-insulating box 1 on the lateral wall of heat-insulating box 1, and spacing groove 8 is located vent 10 top and is linked together with vent 10, and slidable mounting has magnetic seal board 9 in the spacing groove 8, and the specification of magnetic seal board 9 is slightly greater than the specification of vent 10 to improve the leakproofness of magnetic seal board 9 to vent 10, the one side that heat conduction piece 3 is close to vent 10 inlays and is equipped with magnetic stripe 5.

Each expansion ball 7 is filled with thermal expansion medium, each counterweight ball 4 is made of elastic rubber, and the gravity center of the heat conduction block 3 is positioned on the horizontal central axis of the heat conduction block in a natural state.

When the lamp is used in the embodiment, in an initial state, the conducting plate on the shell of the lamp 2 is attached to the electric connecting piece 11, and at the moment, the lamp tube, the conducting plate and the electric connecting piece 11 are connected into the working circuit, so that the lamp tube emits light;

the gravity center of the heat-conducting block 3 is located on the horizontal central axis of the heat-conducting block, as shown in fig. 3, the expansion ball 7 is distributed on the lower half part of the rotary groove 31, the counterweight ball 4 is distributed on the upper half part of the rotary groove 31, at the moment, the coil spring 6 is in a natural state, the temperature in the heat-insulating box 1 can gradually rise along with the increase of illumination time, the heat-conducting block 3 has better heat conductivity and can absorb more heat, when the temperature of the heat conduction block 3 is higher than 30 ℃, the expansion speed of the thermal expansion medium is greatly increased, thereby, the volume of the expansion ball 7 is increased significantly, and at this time, the expansion ball 7 presses the weight ball 4, as shown in fig. 4, the center of gravity of the heat conduction block 3 is shifted upward, thereby leading the heat conduction block 3 to spontaneously rotate 180 degrees, leading the conducting plate to be staggered with the power connection plate 11, cutting off the power of the lamp tube, simultaneously, since one end of the coil spring 6 is connected to the inner wall of the circular groove 32 and the other end is connected to the fixing rod 61, the heat-conducting block 3 rotates to place the coil spring 6 in a stretched state;

meanwhile, the magnetic strip 5 can also rotate 180 degrees, so that repulsive force between the magnetic strip 5 and the magnetic sealing plate 9 is changed into attractive force, the magnetic sealing plate 9 slides upwards along the limiting groove 8 under the action of a magnetic field, the vent 10 is communicated, and gas in the heat insulation box 1 is exchanged with external gas, so that the temperature in the heat insulation box 1 is reduced in an auxiliary manner.

When the lamp 2 does not emit light any more, and after the vent 10 is opened, the temperature in the heat insulation box 1 can be gradually reduced, because the specific heat capacity of the heat conduction block 3 is smaller, the cooling speed of the heat conduction block 3 is faster, the thermal expansion medium in the expansion ball 7 is quickly restored, the volume of the expansion ball 7 is restored to the initial size, at the moment, the gravity center of the heat conduction block 3 is located on the horizontal central axis of the heat conduction block 3 again, namely the force required to be overcome by restoring the coil spring 6 is reduced, under the action of the self deformation force of the coil spring 6, the heat conduction block 3 reversely rotates and then returns to the initial position, the conducting strip is attached to the electric connecting piece 11 again, the lamp 2 is connected into the loop again, the magnetic sealing plate 9 is subjected to the repulsion force of the magnetic strip 5 again, the vent 10 is blocked again after the magnetic sealing plate 9 slides downwards, the closed environment of the.

When the electric connecting piece 11 is attached to the conductive piece in the use of the embodiment, under the action of the elastic piece 12, the electric connecting piece 11 generates certain pressure on the conductive piece, so that the electric connecting piece and the conductive piece are attached more tightly, and the problem that the electric connecting piece 11 is worn and cannot be attached to the conductive piece after long-term use of equipment is solved;

because the edge of the electric connecting piece 11 is turned with a chamfer, as shown in fig. 5, when the electric connecting piece 11 is close to the conductive piece, the stress direction of the electric connecting piece 11 can be changed by the arc-shaped chamfer, so that the electric connecting piece 11 is firstly inclined by an angle, and the electric connecting piece 11 is balanced after the conductive piece slides onto the electric connecting piece 11, therefore, the problem that the electric connecting piece 11 and the conductive piece cannot be attached due to the fact that the side wall of the conductive piece is abutted to each other cannot occur.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
