Abstract
A kind of flame-proof switch door latch apparatus, comprise explosion-proof body and be arranged on explosion-proof shell explosion-proof door closure with it, explosion-proof shell is provided with the operating axis of electric switch with it, operating axis is provided with operating handle, explosion-proof shell is provided with body lock tube with it, in body lock tube, be provided with latch shaft, latch shaft one end is provided with dead bolt, and operating axis is provided with the locking groove corresponding with dead bolt; Latch shaft is provided with handle, and body lock tube is provided with the breach passing through for handle; Explosion preventing gate covers and is provided with door closure lock tube.A kind of flame-proof switch door latch apparatus of the present utility model, the locking that can effectively avoid flame-proof switch of the prior art to occur is not in place, and problem that latch shaft is subject to that power of enforcement bending can not effectively be worked etc., stops potential safety hazard.
Description
Technical field
The utility model relates to colliery mined flame-proof switch technical field, specifically a kind of flame-proof switch door latch apparatus.
Background technology
The locking of the electric part of colliery mined flame-proof switch is comprised of the operator handle outside explosion-proof casing and the bearing pin of locking a door: when flame-proof switch need to overhaul, must have a power failure; When flame-proof switch is normally worked, i.e., during energising operation, the bearing pin of locking a door should be uncapped in order to avoid charged reliably by explosion preventing gate cover locking, occurs potential safety hazard.At present, have the large-scale flame-proof switch of a class, its door closure locking device adopts traditional locking, and this class switch is uncapped or strength is larger at closing time, easily causes not arriving relevant position when latch shaft, and potential safety hazard, appears in the phenomenon that door closure can be opened or close.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of safe and reliable flame-proof switch door latch apparatus.
The utility model solves its technical problem by the following technical solutions.
A kind of flame-proof switch door latch apparatus, comprise explosion-proof body and be arranged on explosion-proof shell explosion-proof door closure with it, described explosion-proof shell is provided with the operating axis of electric switch with it, described operating axis is provided with operating handle, described explosion-proof shell is provided with body lock tube with it, in described body lock tube, be provided with latch shaft, described latch shaft one end is provided with dead bolt, and described operating axis is provided with the locking groove corresponding with dead bolt; Described latch shaft is provided with handle, and described body lock tube is provided with the breach passing through for handle.
Described explosion preventing gate covers and is provided with door closure lock tube, and described door closure lock tube is semicircle.
A kind of flame-proof switch door latch apparatus of the present utility model, after flame-proof switch has a power failure, opens and needs before explosion-proof door closure first, with the operating axis of latch shaft locking electric switch, in case door closure is opened rear switch closure, to cause danger; After explosion-proof door closure is closed, latch shaft can operate explosion preventing gate cover lock the operating handle combined floodgate power transmission of electric switch surely, the locking of having avoided thus flame-proof switch of the prior art to occur is not in place, and problem that latch shaft is subject to that power of enforcement bending can not effectively be worked etc., avoids occurring potential safety hazard.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is latch shaft structural representation;
Fig. 4 is door closure lock tube structural representation;
Fig. 5 is body lock tube structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of flame-proof switch door latch apparatus, comprise explosion-proof body 11 and be arranged on the explosion-proof door closure 6 on explosion-proof body 11, on explosion-proof body 11, the operating axis 4 of mounting electrical switch, is equipped with operating handle 5 on operating axis 4, on explosion-proof body 11, body lock tube 3 is installed, body lock tube 3 inner sleeves have latch shaft 2, as shown in Figure 3, there is dead bolt 7 latch shaft 2 one end, have the locking groove corresponding with dead bolt 78 on operating axis 4; Handle 9 is installed in latch shaft 2; As shown in Figure 5, on body lock tube 3, have the breach 10 passing through for handle 9; On explosion-proof door closure 6, door closure lock tube 1 is installed, as shown in Figure 4, door closure lock tube 1 is semicircle cover, can save rapidoprint realizing under the prerequisite of its effect.
Under the state shown in Fig. 1, while opening explosion-proof door closure 6, first handle 9 is gone to horizontal level, the latch shaft that then moves right 2 makes handle 9 through the breach 10 on body lock tube 3, and dead bolt 7 inserts locking groove 8, then handle 9 is gone to upright position, operating axis 4 is locked, and now, flame-proof switch can not power transmission, the left end of latch shaft 2 departs from door closure lock tube 1, and explosion-proof door closure 6 can rotate, open; After explosion-proof door closure 6 is closed, when flame-proof switch needs power transmission, handle 9 need be gone to horizontal level, now being moved to the left latch shaft 2 makes handle 9 through the breach 10 on body lock tube 3, then handle 9 is turned on upright position, now the left end of latch shaft 2 enters door closure lock tube 1, and it is fixed that latch shaft 2 is about to explosion preventing gate cover lock, can operate the operating handle 5 combined floodgate power transmissions of electric switch.A kind of flame-proof switch door latch apparatus of the present utility model, has solved the locking that flame-proof switch of the prior art may occur not in place, and problem that latch shaft is subject to that power of enforcement bending can not effectively be worked etc., avoids occurring potential safety hazard.
