Detailed Description
Referring to fig. 1-4, the sealing structure of the explosion-proof lamp provided by the utility model comprises an upper shell 1, a lower shell 2 and a sealing block 3, wherein the upper shell 1 is fixedly covered on the lower shell 2 to form a shell, grooves are formed on the upper shell 1 and the lower shell 2 to form wire outlets 4 in a covering state of the upper shell 1 and the lower shell 2, sealing pieces 5 are fixedly arranged on the upper shell 1 and the lower shell 2 and positioned at the peripheral positions of the grooves, the sealing block 3 is fixedly arranged between the upper shell 1 and the lower shell 2, and a conical groove 6 for interference grafting with the sealing pieces 5 is formed on the sealing block 3.
It should be further noted that, the inner sides of the upper casing 1 and the lower casing 2 are provided with clamping grooves, when the explosion-proof lamp is assembled, the transparent sealing plate for sealing and transmitting light is clamped in the clamping grooves on the lower casing 2 of the upper casing 1, the lamp core is positioned in the casing, and the electric wires for energizing the lamp core are led out through the wire outlet holes 4.
When the electric wire is led out from the wire outlet hole 4, in order to further seal the wire outlet hole 4, the two sealing pieces 5 are arc-shaped elastic material members, the diameter of the connecting end of each sealing piece 5 is larger than that of the free end, the two free ends can be abutted against each other, the diameter of the outer end of the conical groove 6 is larger than that of the inner end, and the diameter of the inner end of the conical groove 6 is smaller than that of the free end of each sealing piece 5, so that the sealing pieces 5 are pressed to be abutted against each other after entering the conical groove 6.
The sealing process of the wire outlet 4 is as follows: when the sealing piece 3 is covered outside the sealing piece 5 and the sealing piece 5 enters the conical groove 6, the inner part of the conical groove 6 gives a force to the sealing piece 5, so that the free ends of the two sealing pieces 5 are close to and abutted against each other, and the wire outlet hole 4 is sealed for the first time.
