Abstract
The utility model relates to an anti-explosion electric appliance shell door lid, which belongs to the field of shell structures of flameproof anti-explosion electric appliance products. The utility model comprises a circular lid (1) and a shell body (2). The utility model is characterized in that the circular lid (1) is movably connected with the shell body (2), and a telescopic member is arranged between the circular lid and the shell body. One end of the telescopic member is connected with the circular lid (1), and the other end is connected with the shell body (2). The anti-explosion electric appliance shell lid of the utility model has the advantages of product repair and maintenance time saving and favorable sealing performance, besides, the utility model effectively prevents man-made damage.
Description
Technical field
The utility model belongs to flame-proof type explosion-proof electric equipment products shell mechanism field.
Background technology
The lid of traditional flame-proof type explosion-proof electric equipment products shell is to adopt several bolts of periphery to be fixed on the shell, need 5-10 minute if back out all bolts, make the unlatching and the pass of lid close inconvenience like this, when being carried out maintenance maintenance, product needs the long time, and this fastening means sealing property is not so good, rainy sometimes water intrusion.
The utility model content
Technical problem to be solved in the utility model is in order to overcome above-mentioned defective, to provide a kind of unlatching of lid and pass of making to close conveniently saving product maintenance maintenance time, and the explosion-proof electric apparatus shell door closure of good seal performance.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: explosion-proof electric apparatus shell door closure, comprise dome and housing, and for flexibly connecting, a telescopic member is arranged between dome and the housing, the one end is connected with dome, and the other end is connected with housing.
Described explosion-proof electric apparatus shell door closure, its telescopic member is a hinge; Be flexible special hinge (as watchband).
Described explosion-proof electric apparatus shell door closure has a cannelure on its dome, the left supporter of hinge is stuck in the cannelure, and right supporter is fixedlyed connected with housing.
Described explosion-proof electric apparatus shell door closure, the edge of its dome has teeth groove.
Between the described explosion-proof electric apparatus shell door closure, its dome and housing for being threaded.
Described explosion-proof electric apparatus shell door closure, its housing fillet of screw mouth bottom is provided with detent mechanism; Detent mechanism is made up of keeper, axle, screw and packing ring, after door closure is twisted and is closed, and the special thread of in its buried via hole, screwing on, thus the inoperative personnel can't be uncapped.
Compared with prior art the beneficial effect that the utility model had is: because the utility model has adopted flexible connection, only dome can be opened with half a minute, save the maintenance maintenance time and the good airproof performance of product; Owing to be connected with flexible special hinge (as watchband) between dome and the housing, so when opening dome, hinge can support dome; Detent mechanism is fixed in housing fillet of screw mouth bottom, after door closure is turned on special spanner taken down, and the special thread of in its buried via hole, screwing on, thus the irrelevant personnel can't be uncapped; Screw connection structure is simple, is convenient to processing, and having teeth groove on the dome is opening for the ease of dome.
