Abstract
A coal mine tunnel lamp housing is disclosed, comprising a left end cap and a right end cap, wherein a protection cover is arranged between the left end cap and the right end cap, an electronic circuit is arranged in the right end cap, and a lead wire of the electronic circuit extends beyond the right end cap. The protection cover comprises columns arranged between the left end cap and the right end cap, wherein ring-shaped wires are uniformly arranged around the columns, and each of the ring-shaped wires is provided with a gap. By adopting the above technical solution, the coal mine tunnel lamp housing is advantageous in that the electronic circuit is arranged in the end cap of one side, and therefore the end cap of the other side can be made into a relatively smaller one with smaller space occupied and less raw material used; and the protection cover has certain elasticity and can easily be fit into the two end caps, and the processing precision of the protection cover is not required to be very high.
Description
Technical field
The utility model relates to a kind of coal mine roadway lamp, relates in particular to the tunnel lamp housing that circuit is set in the end cap.
Background technology
Present tunnel lamp generally is mounted between left end cap and the right end cap, is protected by protective cover.Be provided with electronic circuit in left end cap and the right end cap, make that two end caps are all bigger, take certain space, also be unfavorable for saving material.On the other hand, the circumfili of protective cover is an annulus, like this position of column and circumfili all require very accurate, could be corresponding with the pilot hole of two end cap.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency a kind of coal mine roadway lamp housing is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of coal mine roadway lamp housing comprises left end cap and right end cap, between left end cap and right end cap, protective cover is set, and in right end cap, is provided with electronic circuit, and the lead-in wire of electronic circuit reaches outside the right end cap.
Above-mentioned coal mine roadway lamp housing, said protective cover comprises the column that is assemblied between left end cap and the right end cap, evenly is provided with circumfili in the column outside, is provided with breach on the every circumfili.
Adopt technique scheme; The utility model has following advantage: because electronic circuit only is installed in the end cap of a side, the opposite side end cap just can be done smallerly relatively, and it is little to take up room; And the raw material of usefulness are also few; Protective cover has certain elasticity, makes requirement on machining accuracy so not strict, and protective cover is assembled in two end caps easily.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
A kind of coal mine roadway lamp housing as shown in Figure 1 comprises left end cap 1 and right end cap 6, between left end cap 1 and right end cap 6, protective cover is set, and in right end cap 6, is provided with electronic circuit, and the lead-in wire of electronic circuit reaches outside the right end cap.Said protective cover comprises the column 4 that is assemblied between left end cap 1 and the right end cap 6, evenly is provided with circumfili 2 in column 4 outsides, is provided with breach 3 on the every circumfili.
