Description
Technical field
The present invention relates to a kind of jack safety devices, and in particular to a kind of subway door leaf jack safety device.
Background technique
Subway people's air defense partition door use is normally normally open in subway tunnel, after which opens in place, it is necessary to make
With jack safety device fix in position, door leaf is forbidden to be freely rotated, otherwise will be brought extremely to the normal operation of railcar
Serious adverse consequences.The anti-partition door jack safety device of original place iron man, whole more heavy, opening and closing is inconvenient, and shell is only
Using 2mm thin plate, security performance is poor, subway door leaf close after, personnel can arbitrarily open jack safety device, by it is artificial because
Element is affected, and brings great security risk to railcar normal operation.
Summary of the invention
Goal of the invention: purpose of the invention is to overcome the shortcomings in the prior art, provides a kind of easy to operate, stabilization
Property and safety greatly improve, the improved subway people's air defense partition door jack safety device that cost declines to a great extent.
Technical solution: in order to solve the above-mentioned technical problem, a kind of improved subway people's air defense partition door use of the present invention
Jack safety device, it includes the shell being located on door leaf, and lower part is equipped with casing in the shell, and described sleeve pipe lower end is stretched
The shell out is equipped with tapered end in described sleeve pipe, and the tapered end upper end is connected by pin shaft I with pivoted arm, and the pivoted arm passes through
Pin shaft II is connected with shell, is equipped with live-in handle in the pivoted arm upper end, lock is equipped on the corresponding terrace in the tapered end lower end
Seat is equipped with limit hole I on the lock, limit hole II is equipped in described sleeve pipe lower part, in the limit hole I or limit hole II
It is interior to be equipped with clamping screw.
The pivoted arm is connect with live-in handle threads.
The pivoted arm is v-shaped structure.
The shell is stretched out in the pivoted arm upper end.
The tapered end matches setting with lock.
The utility model has the advantages that compared with prior art, the present invention its remarkable advantage is: overall structure setting of the present invention rationally, is adopted
With round steel entirety vehicle system, it is firm to stablize, and after subway door leaf is opened in place, door leaf need to be fixed, and unclamps clamping screw, in weight
Power act on lower lock head decline, into lock, clamping screw is fastened in limit hole II, safety device locking in place, live-in handle
Detachably, convenient for on-demand, irrelevant personnel is avoided to contact；Before closing subway door leaf, clamping screw, the connection of live-in handle are unclamped
Pivoted arm pushes live-in handle, and tapered end lifts, clamping screw is placed in limit hole I, and safety device is in the open state, can be into
Row subway door leaf freely opens and closes, and operation of the present invention is simple, using reliable, runs smoothly, security performance greatly improves, and solves
The security risk that railcar operates normally in the past, while it being effectively saved cost, meet actual operation requirements.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of improved subway people's air defense partition door jack safety device of the present invention, it includes
The shell 2 being located on door leaf 1, lower part is equipped with casing 3 in the shell 2, and the shell 2 is stretched out in 3 lower end of described sleeve pipe, in institute
State and be equipped with tapered end 4 in casing 3,4 upper end of tapered end is connected by pin shaft I 5 with pivoted arm 6, the pivoted arm 6 pass through pin shaft II 7 and
Shell 2 is connected, and is equipped with live-in handle 8 in 6 upper end of pivoted arm, lock 9 is equipped on the corresponding terrace in 4 lower end of tapered end,
It is equipped with limit hole I 10 on the lock 9, limit hole II 11 is equipped in 3 lower part of described sleeve pipe, in the limit hole I 10 or limit
Position is equipped with clamping screw 12 in hole II 11；The pivoted arm 6 is threadedly coupled with live-in handle 8；The pivoted arm 6 is v-shaped structure；It is described
The shell 2 is stretched out in 6 upper end of pivoted arm；The tapered end 4 matches setting with lock 9.Overall structure setting of the present invention is reasonable, using circle
Steel entirety vehicle system, it is firm to stablize, and after subway door leaf is opened in place, door leaf need to be fixed, and unclamps clamping screw, makees in gravity
Declined with lower lock head, into lock, clamping screw is fastened in limit hole II, and in place, live-in handle is removable for safety device locking
It unloads, convenient for on-demand, irrelevant personnel is avoided to contact；Before closing subway door leaf, clamping screw is unclamped, the connection of live-in handle turns
Arm pushes live-in handle, and tapered end lifts, clamping screw is placed in limit hole I, and safety device is in the open state, can carry out
Subway door leaf freely opens and closes, and operation of the present invention is simple, using reliable, runs smoothly, and security performance greatly improves, solve with
The security risk that preceding railcar operates normally, while it being effectively saved cost, meet actual operation requirements.
The present invention provides a kind of thinking and methods, and there are many method and the approach for implementing the technical solution, the above institute
Stating is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, is not being departed from
