The structure has the defects that the screw connection and the thread connection cannot be combined, and the connection strength is limited; in addition, when the screw rod or the thread of the structure is connected or screwed, the screw rod or the thread after fastening is loosened due to the fact that the miner lamp is frequently touched, so that the lamp cover and the lamp barrel are not firmly connected, normal use of the miner lamp is affected, and serious potential safety hazards are brought to underground coal mines.
Disclosure of Invention
An object of the utility model is to overcome the not enough of above-mentioned technique, provide a combine screw rod to connect and threaded connection as an organic whole, joint strength is better, more difficult for the mining flame proof of the improved generation and intrinsic safety type LED lamp lid that becomes flexible.
In order to realize the purpose of the utility model, the utility model adopts the technical scheme that: an improved mining explosion-proof and intrinsic safety type LED lamp cover comprises a lamp cover body and a lamp barrel which are arranged up and down, wherein the lamp cover body is arranged at the upper end of the lamp barrel; the lamp cap body comprises a circular cover plate and a circular ring II capable of being inserted into the annular groove, the circular ring II is fixed at the center of the lower surface of the cover plate, threads II matched with the threads I are processed on the inner wall and the outer wall of the circular ring II, the length of the circular ring II is equal to that of the circular ring I, the thickness of the circular ring II is equal to the distance between the inner wall of the circular ring I and the outer wall of the lamp tube, and when the lamp cap body is assembled on the lamp tube, the circular ring II is screwed into the annular groove.
Furthermore, the diameter of the cover plate is larger than that of the circular ring II, and a plurality of screw connecting holes II are formed in the outer edge of the cover plate at equal intervals along the circumferential direction; the periphery of ring I is equipped with an annular plate, and the external diameter of annular plate equals the diameter of apron, and when the lamp lid body was assembled on a lamp section of thick bamboo, annular plate and apron laminating offered on the annular plate and correspond with screw rod connecting hole II and communicating screw rod connecting hole I.
Furthermore, counter bores for placing the head of the screw and a screw cap are formed in the screw connecting hole I and the screw connecting hole II.
Furthermore, the lamp cylinder, the ring I, the connecting piece and the annular plate form an integrated structure through injection molding.
Furthermore, the screw connecting holes I and the screw connecting holes II are at least provided with 3.
Further, the cover plate and the circular ring II form an integrated structure through injection molding.
Furthermore, a hoisting ring is installed in the center of the upper surface of the cover plate.
The utility model has the advantages that: the screw rod connection and the thread connection are combined, so that the connection strength is higher, and the sealing performance is better; the counter bore is arranged, so that the screw does not extend out of the surface of the end cover after being fastened, and the screw is prevented from being loosened due to the fact that the screw is contacted by external force; the double-layer thread fastening mode is adopted, and the high connection fastening strength is achieved even if screw connection is not arranged.
