By using the opening angle retention mechanism of the emergency door of the subway shielded door, provided by the invention, stable angle retention and location functions are achieved after the emergency door of the subway shielded door is opened.
Description
Technical field
The escape door that the present invention relates to a kind of angle maintaining body, particularly a kind of subway shield door is opened rear angle maintaining body.
Background technology
In present screen door, no matter be shield door or the half high safety door of overall height, generally be provided with escape door (or claiming escape).Its effect is to be convenient to the personnel escape when emergency occurs, and for example its effect of the escape door of subway shield door is in urgent situation personnel to be escaped from the tunnel.Between the upper transverse frame of the escape door of existing subway shield door and lintel beam, be provided with the angle maintaining body after escape door is opened, like this can so that in the evacuating personnel process escape door can be in all the time open mode.But the inventor finds, existing escape door is opened rear angle maintaining body, and to have a location structure confining force little, can't satisfy actual operation requirements, and the defective that lost efficacy easily needs to improve.
Summary of the invention
Defects in view of the prior art existence, the object of the present invention is to provide a kind of escape door of subway shield door to open rear angle maintaining body, this angle maintaining body can provide the escape door of subway shield door to have stable angle maintenance and location after opening.
To achieve these goals, the escape door of a kind of subway shield door provided by the invention is opened rear angle maintaining body, comprising:
One is arranged at the sliding support bearing on the end face of escape door upper transverse frame, described sliding support bearing is provided with a slideway, be provided with a slide block that can in slideway, slide in the described slideway, described slide block is provided with the first locking part, described slideway when escape door is closed away from an end of described slide block also be provided with when escape door is opened fully can with the second locking part of described the first locking part interlock locking;
One pull bar that in escape door opening and closing process, affects described slide block in described slideway, to slide, described pull bar one end and escape door lintel beam are hinged, and the other end and described slide block are hinged.
As preferably, described the first locking part is the projection of extending to the direction of described the second locking part, but the clamping piece that described the second locking part is the described projection of interlock.
As preferably, described clamping piece is provided with bite towards an end of described projection, and described bite is two Clip Reeds to establishing, form between two described Clip Reeds one with the elastic bayonet lock of described protruding interlock.
As preferably, described projection is the middle part spindle wider than two ends.
As preferably, also be provided with a stator on the described escape door lintel beam, described pull bar and described stator are hinged.
Compared with the prior art, the escape door of subway shield door of the present invention is opened rear angle maintaining body, by the projection on the slide block of being located in the slideway and the interlock of bite after escape door is opened that is arranged at ways-end, can provide the escape door of subway shield door after opening, to have stable angle maintenance and location.
Description of drawings
Fig. 1 is the top view that the escape door of subway shield door of the present invention is opened rear angle maintaining body.
Fig. 2 is the front view after the escape door of subway shield door of the present invention is opened rear angle maintaining body and escape door is connected.
The specific embodiment
Below in conjunction with accompanying drawing structure of the present invention is further described in detail.
As depicted in figs. 1 and 2, the escape door of a kind of subway shield door provided by the invention is opened rear angle maintaining body, comprising:
One is arranged at the sliding support bearing 3 on the end face of escape door upper transverse frame 7, and described sliding support bearing 3 is provided with a slideway 31, and being provided with one in the described slideway 31 can be in the slide block 4 of slideway 31 interior slips, and described slide block 4 is provided with the first locking part; Described slideway 31 when escape door is closed away from an end of described slide block 4 also be provided with when escape door is opened fully can with the second locking part of described the first locking part interlock locking; In the present embodiment, described the first locking part is the projection 41 of extending to the direction of described the second locking part, but described the second locking part described clamping piece of protruding 41 5 that is interlock.Described clamping piece 5 towards described protruding 41 1 ends be provided with one when escape door is opened fully can with the bite of described protruding 41 interlocks, bite is by two Clip Reeds to establishing in the present embodiment, namely Clip Reed 51 and Clip Reed 52 consist of; As shown in Figure 1, form between described Clip Reed 51 and the described Clip Reed 52 one can with the elastic bayonet lock 53 of described protruding interlock, and guarantee that with clamping described protruding 41 angle keeps and the location after escape door is opened as chucking power by the elastic force that Clip Reed 51 and Clip Reed 52 provide, be compared to prior art, this kind mode can provide larger confining force and stable angle maintenance effect; Comprise that also one affects described slide block 4 at the pull bar 1 of described slideway 31 interior slips when escape door opens and closes, described pull bar 1 one ends and escape door lintel beam 8 are hinged, and the other end and described slide block 4 are hinged.
By the aforesaid angle maintaining body of the present invention, when escape door is opened, escape door upper transverse frame 7 is mobile laterally with respect to escape door lintel beam 8, drive pull bar 1 around the hinged place rotation of pull bar 1 with escape door lintel beam 8, pull bar 1 affects slide block 4 to move relative to slideway 4 at slideway 31 interior ends to slideway 4.Until escape door is when opening fully, in the present embodiment, pull bar 1 and 7 one-tenth 90 ° of escape door upper transverse frames, at this moment, the projection 41 of slide block 4 is pushed in the elastic bayonet lock 53 of clamping piece 5 of slideway 31 ends, and is clamped by Clip Reed 51 and Clip Reed 52, is not having in the situation of External Force Acting, projection 41 can not withdraw from elastic bayonet lock 53, thereby has realized that the angle after escape door is opened keeps and the location.
In addition, in order to cooperate the elastic bayonet lock 53 that is formed by Clip Reed 51 and Clip Reed 52 so that preferably confining force to be provided, as preferably, described protruding 41 can be set to the slightly wide spindle in middle part, can make like this projection 41 still maintain preferably clamping and interlock effect when interior entering elastic bayonet lock 53.
Further again, as preferably, during actual installation angle maintaining body of the present invention, can on described escape door lintel beam 8, be provided with again a stator 2, then that described pull bar 1 and described stator 2 is hinged.Can reach the good effect that installs and fixes with this.
Certainly, the above is preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also are considered as protection scope of the present invention.
