Description
Technical field
The utility model relates to a kind of jack safety devices, and in particular to a kind of subway door leaf jack safety dress
It sets.
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: the purpose of this utility model is to overcome deficiency in the prior art, provide it is a kind of easy to operate,
Stability 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 described in the utility model
Door jack safety device, it includes the shell being located on door leaf, and lower part is equipped with casing in the shell, under described sleeve pipe
The shell is stretched out at end, and tapered end is equipped in described sleeve pipe, and the tapered end upper end is connected by pin shaft I with pivoted arm, the pivoted arm
It is connected by pin shaft II with shell, is equipped with live-in handle in the pivoted arm upper end, is set on the corresponding terrace in the tapered end lower end
There is lock, limit hole I is equipped on the lock, limit hole II is equipped in described sleeve pipe lower part, in the limit hole I or limit
Clamping screw is equipped in hole II.
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 the utility model is compared with prior art, remarkable advantage is: the setting of the utility model overall structure
Rationally, using 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 locking screw
Bolt, tapered end declines under the effect of gravity, and into lock, clamping screw is fastened in limit hole II, and safety device locking is in place, living
Formula handle is detachable, convenient for on-demand, irrelevant personnel is avoided to contact；Before closing subway door leaf, clamping screw, live-in hand are unclamped
Handle connects pivoted arm, pushes live-in handle, and tapered end lifts, clamping screw is placed in limit hole I, and safety device is in opening state
State can carry out freely opening and closing for subway door leaf, and the utility model is easy to operate, using reliable, run smoothly, security performance is significantly
It improves, solves the security risk that former railcar operates normally, while being effectively saved cost, meet actual use and want
It asks.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is further described 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 described in the utility model, it
Including 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,
Tapered end 4 is equipped in described sleeve pipe 3,4 upper end of tapered end is connected by pin shaft I 5 with pivoted arm 6, and the pivoted arm 6 passes through pin shaft II
7 are connected with shell 2, are equipped with live-in handle 8 in 6 upper end of pivoted arm, lock is equipped on the corresponding terrace in 4 lower end of tapered end
9, limit hole I 10 is equipped on the lock 9, is equipped with limit hole II 11 in 3 lower part of described sleeve pipe, in the limit hole I 10 or
Clamping screw 12 is equipped in limit hole II 11；The pivoted arm 6 is threadedly coupled with live-in handle 8；The pivoted arm 6 is v-shaped structure；Institute
It states 6 upper end of pivoted arm and stretches out the shell 2；The tapered end 4 matches setting with lock 9.The setting of the utility model overall structure is reasonable,
Using 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,
Gravity lower lock head decline, into lock, clamping screw is fastened in limit hole II, safety device locking in place, live-in hand
Handle is detachable, convenient for on-demand, irrelevant personnel is avoided to contact；Before closing subway door leaf, clamping screw is unclamped, live-in handle connects
Switch through arm, push live-in handle, tapered end lifts, clamping screw is placed in limit hole I, and safety device is in the open state, can
Subway door leaf is carried out freely to open and close, the utility model is easy to operate, using reliable, runs smoothly, and security performance greatly improves,
It solves the security risk that former railcar operates normally, while being effectively saved cost, meet actual operation requirements.
The utility model provides a kind of thinking and method, and there are many method and the approach for implementing the technical solution, with
It is only preferred embodiments of the present invention described in upper, it is noted that for those skilled in the art,
