[0026] The heat dissipation mechanism 5 includes a heat dissipation plate 501, a circulation cavity 502 and a connecting pipe 503. The inner cavity of the heat dissipation plate 501 is provided with a circulation cavity 502. The connecting pipes 503 are fixedly installed at both ends of the circulation cavity 502. The cross section of the circulation cavity 502 is an "S"-shaped structure. The surface of the mounting frame 2 is rotatably provided with fixing rods 6 at equal intervals. The bottom outer side of the mounting frame 2 is symmetrically provided with fixing grooves 9. The outer side of the heat dissipation plate 501 is provided with card slots 7 at equal intervals. The card slots 7 match the size of the fixing rod 6.

[0027] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the device is in use, the personnel installs the heat conducting plate 4 into the inner cavity of the mounting frame 2, and then puts the heat sink 501 into the interior of the mounting frame 2 again. When the slot 7 on the side of the heat sink 501 corresponds to the fixing rod 6 on the outside of the mounting frame 2, the personnel rotates the fixing rod 6 and inserts one end of the fixing rod 6 into the inner cavity of the slot 7, so that the heat sink 501 and the heat conducting plate 4 can be fixedly installed in the inner cavity of the mounting frame 2. When the lamp beads inside the headlight body 1 generate heat during long-term lighting, the heat can be discharged outward through the heat conducting plate 4, and then the heat can be discharged outward through the coolant inside the internal circulation cavity 502 of the heat sink 501, so as to avoid the heat inside the headlight body 1 from accumulating inside the mounting frame 2, thereby further improving the heat dissipation effect of the device.

[0028] Further, a mounting seat 3 is arranged outside the lamp body 1, and a mounting mechanism 8 is symmetrically arranged inside the mounting seat 3. The mounting mechanism 8 includes a mounting cavity 801, a pull rod 802 and a spring 803. The mounting cavity 801 is opened inside the mounting seat 3, and a pull rod 802 is installed in the inner cavity of the mounting cavity 801. A spring 803 is installed on the surface of the pull rod 802. The cross section of the pull rod 802 is a "+"-shaped structure, and the size of one end of the pull rod 802 matches the size of the fixing groove 9.

[0029] Specifically, Figure 1 , Figure 2 As shown, when personnel install the headlight body 1, after installing the mounting frame 2 on the rear side of the headlight body 1 into the interior of the mounting seat 3, pull the pull rod 802 outward, pull the pull rod 802 into the interior of the mounting cavity 801, and install the mounting frame 2 into the interior of the mounting seat 3, so that the fixing groove 9 outside the mounting frame 2 corresponds, release the pull rod 802, and the pull rod 802 will pop outward under the elastic action of the spring 803 on its surface, and then the pull rod 802 can be inserted into the interior of the fixing groove 9, so that the headlight body 1 can be quickly installed into the interior of the mounting seat 3 for use.

Then, external air can be sucked into the inner cavity of the mounting frame 2 through a group of cooling fans 11, and then the heat inside the mounting frame 2 can be discharged to the outside through another group of cooling fans 11, thereby improving the heat dissipation effect of the device to a certain extent.

[0032] Working principle: install the heat conducting plate 4 into the inner cavity of the mounting frame 2, and then put the heat sink 501 into the mounting frame 2 again. When the slot 7 on the side of the heat sink 501 corresponds to the fixing rod 6 on the outside of the mounting frame 2, the personnel rotates the fixing rod 6 and inserts one end of the fixing rod 6 into the inner cavity of the slot 7, so that the heat sink 501 and the heat conducting plate 4 can be fixedly installed in the inner cavity of the mounting frame 2. When the lamp beads inside the headlight body 1 generate heat during long-term lighting, the heat can be discharged outward through the heat conducting plate 4, and then the heat can be discharged outward through the coolant inside the internal circulation cavity 502 of the heat sink 501, so as to avoid the heat inside the headlight body 1 from accumulating inside the mounting frame 2.

[0033] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
