Cover plate, it is fixedly connected with light cover, for clamping switch locking plate.
Of the present invention have the explosion-proof lamp preventing free-hand Unclosing structure, it is characterized in that, described lamp cylinder gap slot is semicircular indentations groove.
Of the present invention have the explosion-proof lamp preventing free-hand Unclosing structure, it is characterized in that, also lays retainer plate, for the position of stationary positioned ball in described light cover holddown groove.
Of the present invention have the explosion-proof lamp preventing free-hand Unclosing structure, it is characterized in that, described switch lock stator sliding part is also provided with slip flange.
Of the present invention have the explosion-proof lamp preventing free-hand Unclosing structure, it is characterized in that, described slip flange is formed after being bent by sliding part.
Of the present invention have the explosion-proof lamp preventing free-hand Unclosing structure, it is characterized in that, described cover plate outwards bends in handle handle.
Of the present invention have the explosion-proof lamp preventing free-hand Unclosing structure, it is characterized in that, described light cover is also provided with the second draw-in groove, for chimeric cover plate.
Of the present invention have the explosion-proof lamp preventing free-hand Unclosing structure, it is characterized in that, described cover plate is fixedly connected with by screw with light fixture.
Use and of the present invention there is the explosion-proof lamp preventing free-hand Unclosing structure, can avoid when using explosion-proof lamp because user's maloperation or other surprisingly cause explosion-proof lamp to be opened and lose flame proof effectiveness, even cause the problem of security incident.The present invention has that structure is simple, cost of manufacture is cheap, effectively can prevent the free-hand advantage opening explosion-proof lamp.

Detailed description of the invention
As Figure 1-5, a kind of have the explosion-proof lamp preventing free-hand Unclosing structure, comprises lamp cylinder 03, light cover 01, spring 02, place kick 06, switch lock stator 07 and cover plate 04, wherein inwall place, lamp cylinder 03 bottom is provided with gap slot 031, light cover 01 is provided with holddown groove and draw-in groove 011, and lay spring 02, place kick 06 in described holddown groove successively, switch lock stator 07 can cover place kick 06, in order to the position of further stationary positioned ball 06, in light cover 01 holddown groove, retainer plate 08 can also be laid.
As shown in Figure 2,3, lamp cylinder 03 gap slot 031 can be semicircular indentations groove, but also can be the gap slot of other arc length, screws rear switch lock stator end can be engaged in gap slot as long as meet lamp cylinder and light cover.
As shown in Figure 6,7, switch lock stator 07 comprises the screens portion in draw-in groove 071 and can at the sliding part 072 of light cover surface sliding of can being embedded in, end, described screens portion 071 can be fastened in lamp cylinder gap slot 031, and described sliding part 072 is provided with the locating hole 073 mated with location sphere.The screens portion 071 of stirring sliding part 072 to the switch lock stator of slide switch locking plate is sticked in lamp cylinder gap slot 031, now place kick 06 just coordinates with locating hole 073 or fastens, just can not rotating separation between lamp cylinder and light cover, thus the function that prevents light fixture from opening can be realized; By applying pressure to locating hole place place kick 06, the sliding part 072 of toggle switch locking plate, makes spring 02 be compressed simultaneously, screens portion 071 departs from lamp cylinder gap slot 031, now place kick 06 also departs from locating hole 073, and lamp cylinder and light cover just can rotate freely, thus can open light fixture.
Slidably reciprocate on lid 01 for ease of switch lock stator 07, the sliding part 072 of switch lock stator is provided with slip flange 074 further, and slip flange 074 is by being formed after bending sliding part 072.
As shown in Figure 1, cover plate 04 is fixedly connected with light cover 01, for covering draw-in groove 011 and clamping switch locking plate 07.Usually, cover plate 04 is fixedly connected with by screw 05 with light cover 01.Usually, use as handle in handle shape after cover plate 04 outwards bends, be convenient to fetching of explosion-proof lamp and carry.
As shown in Figure 4,5, light cover 01 is also provided with the second draw-in groove 012, facilitates the installation of cover plate 04, and can be convenient to horizontal positioned light fixture when light fixture is on the shelf for chimeric cover plate 04.
Use of the present invention have prevent the free-hand explosion-proof lamp opened, can use explosion-proof lamp time avoid because user's maloperation or other surprisingly cause explosion-proof lamp to be opened and lose flame proof effectiveness, even cause the problem of security incident.The present invention has that structure is simple, cost of manufacture is cheap, effectively can prevent the free-hand advantage opening explosion-proof lamp.
