Abstract
The utility model discloses an anti-damage structure applicable to a key hole of a rail transit emergency exit. The anti-damage structure comprises a shell (1) which is sleeved outside a lock body (9), wherein an opening (3) is formed in the front end surface (2) of the shell (1), at the front end of a lock hole; the opening (3) passes through the front end surface (2) and is internally provided with a baffle (4); vertical sliding grooves (5) are formed in the front end surfaces (2) on both sides of the opening (3); the two sides of the baffle (4) are installed inside the sliding grooves in a sliding manner; and a guide barrel (6) is further arranged at the front end of the lock hole. The anti-damage structure has the beneficial effects that due to the arrangement of the shell and the baffle, the lock hole can be hidden inside the shell, the position of the lock hole cannot be found only by observation in a station, so that the lock hole is prevented being damaged; and due to the arrangement of the guide barrel, workers can rapidly and conveniently insert a key to unlock, so that the unlocking time is saved, and more time for evacuating passengers in emergency is obtained.
Description
Technical field
The utility model relates to the locking device technical field, particularly is applicable to the anti-tamper structure of rail transit safety door keyhole.
Background technology
The keyhole of rail transit safety door is to be used for the release device of the manually opened safety door of staff under maintenance or emergency, at present, that installs on rail transit safety door is the lockset with keyhole, lockhole is exposed to the surface, this just for lockset even the safety of safety door caused impact.Exposed lockhole is very easily inserted by unlocking tool, and then safety door is opened, and the safety of Metro Passenger is threatened.Or exposed lockhole is destroyed by instrument or is stopped up by foreign material, and in case of emergency timely smooth opening lockset, threaten to passenger's safety equally.How present lockset improves the preventing destructing performance of lockset by structure or the material that improves locking device, but can not eliminate the exposed threat that brings of lockhole.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, a kind of effective hidden lockhole is provided, prevents the anti-tamper structure that is applicable to the rail transit safety door keyhole that lockhole is destroyed.
the purpose of this utility model is achieved through the following technical solutions: the anti-tamper structure that is applicable to the rail transit safety door keyhole, be applicable to the anti-tamper structure of rail transit safety door keyhole, it comprises the housing that is set in the lock body outside, the front end face that housing is positioned at the lockhole front end is provided with opening, opening runs through front end face, the setting position of opening is corresponding with lockhole, be provided with baffle plate in opening, be equipped with vertical chute on the front end face of opening both sides, the both sides of baffle plate are slidably mounted in chute, the front end of lockhole also is provided with leads the circle of position cylinder, lead the internal diameter of circle of position cylinder greater than the external diameter of lockhole.
Describedly lead the front end of circle of position cylinder and the spacing of front end face inwall is 5～10cm.
Described front end face is comprised of the top layer that connects as one and internal layer, and opening runs through top layer and internal layer, and vertical chute is arranged on internal layer.
The utlity model has following advantage: the setting of housing of the present utility model and baffle plate can be hidden in housing with lockhole, AT STATION in people only can not determine the lockhole position by observation, thereby prevent that lockhole is destroyed.
Lead arranging of circle of position cylinder and can facilitate the staff to insert quickly and accurately key to open lock, save uncaging time, in case of emergency strive for the more time for passenger evacuation.
By decorating, top layer and baffle plate are arranged to color with the identical style in installation site, more effective hidden lockhole.
Description of drawings
Fig. 1 is structural representation of the present utility model
Fig. 2 is right TV structure schematic diagram of the present utility model
In figure, the 1-housing, the 2-front end face, the 3-opening, the 4-baffle plate, 5-vertical chute, 6-are led the circle of position cylinder, 7-top layer, 8-internal layer, 9-lock body.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1 and Figure 2, be applicable to the anti-tamper structure of rail transit safety door keyhole, it comprises the housing 1 that is set in lock body 9 outsides, the front end face 2 that housing 1 is positioned at the lockhole front end is provided with opening 3, and opening 3 runs through front end face 2, and the setting position of opening 3 is corresponding with lockhole, being opening 3 is positioned at same vertical height, same level position with lockhole, be provided with baffle plate 4 in opening 3, be equipped with vertical chute 5 on the front end face 2 of opening 3 both sides, the both sides of baffle plate 4 are slidably mounted in chute.The setting of housing 1 and baffle plate 4 can be hidden in housing 1 with lockhole, AT STATION in people only can not determine by observation and the lockhole position prevent that effectively lockhole is destroyed.The front end of lockhole also is provided with leads circle of position cylinder 6, lead the internal diameter of circle of position cylinder 6 greater than the external diameter of lockhole, lead arranging of circle of position cylinder 6 and can facilitate the staff to insert quickly and accurately key to open lock, save uncaging time, in case of emergency strive for the more time for passenger evacuation.Leading the front end of circle of position cylinder 6 and the spacing of front end face 2 inwalls is 5～10cm, further reduces the destroyed possibility of lockhole, makes people namely allow to find lockhole, can not contact easily lockhole.Described front end face 2 is comprised of the top layer 7 that connects as one and internal layer 8, opening 3 runs through top layer 7 and internal layer 8, vertical chute 5 is arranged on internal layer 8, top layer 7 only arranges opening 3, the interior installation baffle plate 4 of opening 3, by decorating, top layer 7 and baffle plate 4 are arranged to color with the identical style in installation site, more effective hidden this device.
The course of work of the present utility model is as follows: first lift baffle plate 4, then insert key, under the guiding of leading circle of position cylinder 6, key is located smoothly, can open lock or shut, and extracts key after operation is completed, and puts down baffle plate 4 and gets final product.
