Description

Technical Field

[0001] The present invention relates to the technical field of explosion-proof searchlights, and specifically to an explosion-proof searchlight with a connection structure. Background Art

[0002] The explosion-proof searchlight has a long irradiation distance and wide applications. Its outer shell is made of high-strength alloy material and has a precise structure design, with high anti-strong collision and impact capabilities.

[0039] The clamping plate assembly 45 includes a connecting block 451 which is threadedly connected to the surface of the bidirectional threaded rod 44. The bottom of the connecting block 451 is fixedly connected to a connecting plate 452. The bottom of the connecting plate 452 is fixedly connected to two front and rear stoppers 453. A fixing rod 454 is fixedly connected between the opposite sides of the two stoppers 453. A clamping plate 455 is rotatably connected to the surface of the fixing rod 454. The top end of the clamping plate 455 is provided with a convex head portion 456. The bottom of the connecting plate 452 is fixedly connected to a stop plate 457.

The bidirectional threaded rod 44 rotates and drives the two clamping plates 455 to approach each other through the clamping plate assembly 45, so as to clamp the two sides of the placed object, thus realizing installation and connection. Then rotate the searchlight main body 1 to adjust the illumination angle. After the searchlight main body 1 is used for a period of time, the lampshade is stained with dust. By swinging the handle 314, the ring 36 rotates back and forth. The rotation of the ring 36 is transmitted to the gear 33. The rotation of the gear 33 drives the rotation of the lead screw 32. The rotation of the lead screw 32 drives the up and down movement of the sector baffle 310 through the threaded sleeve 38 and the L-shaped rod 39. The up and down movement of the sector baffle 310 cleans the surface of the lampshade through the cleaning sponge 311. In addition, when the searchlight is not in use, swing the handle 314 to one side, so that the four sector baffles 310 are closed, thus protecting the lampshade. Then rotate the knob 46 to make the two clamping plates 455 move away from each other, and rotate the clamping plates 455 so that the clamping plates 455 enter the clamping groove 43.
