Description

Subway platform dodge gate release mechanism

The utility model belongs to a kind of release mechanism that is used for subway platform screen door dodge gate.

Traditional fireproofing door lock release mechanism general adopt key combined and handle is unblanked, consider the Safety Design requirement of fireproofing door lock, general inside and outside handle, the single tongue structure of adopting, the inner rotation part of handle links to each other with spring with the lock core assembly, the other end of spring is connected with locking bolt or dead bolt, the rotation of handle and lock core assembly causes in the axial direction flexible of spring, thereby lock is opened and closed, and utilizes the elastic force of spring that locking bolt or dead bolt are resetted after unblanking.In the design of subway platform screen door, requirement is provided with release mechanism on dodge gate, the passenger who makes in platform side can not at will open dodge gate, satisfy safety requirements to dodge gate, and in train rail one side, anyone can open dodge gate, thereby be implemented in escaping function in emergency circumstances, simultaneously because the particular design of subway platform screen door need, requiring the dodge gate door lock is the structure that locks up and down, lock point not in same place, and has certain distance with release mechanism like this, traditional fireproofing door lock release mechanism can not be directly used in the subway platform screen door.

The purpose of this utility model is to provide a kind of release mechanism for the dodge gate in the subway platform screen door.

The purpose of this utility model is achieved in that the utility model comprises locking bolt, spring and is installed in the handlebar unlocked mechanism and the key release mechanism of a both sides, inside and outside respectively, and described locking bolt is installed in the top of a body, and spring is located at the below of locking bolt; Described handlebar unlocked mechanism comprises handle base and handle, handle base is fixed on the body, and an end of handle is installed in the handle base and turns, and handlebar unlocked mechanism also comprises the couple axle that is positioned at a body, it and handle are fixed as one, and couple axle links to each other with locking bolt by wire rope; Described key release mechanism comprises lock, lock tube and lock core rotating shaft, lock is fixed on the body, lock tube is fixed in the lock, the lock core rotating shaft be contained in the lock tube and can about freely rotate, the outer end of lock core rotating shaft is that cross section is non-circular lock shaft, the inner in the lock core rotating shaft is provided with flange, is attached to the top of couple axle.Releasing process of the present utility model is as follows: when swing handle, couple axle moves downward, the locking bolt compression spring that drive is connected on the wire rope moves downward, thereby lock is opened, and when opening the lock with the key, lock core rotating shaft and flange rotate, flange moves downward, couple axle is pressed down, drive the locking bolt that is connected on the wire rope and move downward, thereby lock is opened.Handle unclamped or after key took out, then locking bolt was got back to original position automatically under the restoring force of spring.

Technique effect of the present utility model is: lockhole of the present utility model is located at platform one side on the body, passenger in platform side can not at will open dodge gate, have only subway staff available dedicated key to open, satisfied safety requirements to dodge gate, and handle is located at train rail one side, with movable door-lock opening, realized the escaping function when dodge gate is in emergency circumstances as fire at anyone rotatable handles of this side.In addition, the utility model is a mechanical release mechanism completely, also can realize unlocking function under powering-off state, satisfied the subway shield door system design to dodge gate in case of emergency to the requirement of release mechanism.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the vertical view cutaway drawing after the utility model is installed in the dodge gate doorframe.

Fig. 2 is the A-A sectional view of Fig. 1.

Fig. 3 is the B-B sectional view of Fig. 1.

Dodge gate in the subway shield door system comprises doorframe and is installed in the interior glass of doorframe.The dodge gate release mechanism of present embodiment comprises locking bolt, spring, handlebar unlocked mechanism and key release mechanism, and locking bolt is arranged in the hole at dodge gate doorframe top, and spring is below locking bolt, and this part structure is not shown in the accompanying drawings; As depicted in figs. 1 and 2, handlebar unlocked mechanism is installed on the perpendicular material 1 of doorframe, it is by handle base 2, handle 3, couple axle 4 and straight pin 5 are formed, handle base 2 is expected on 1 perpendicular by screw, one end of handle 3 is positioned at handle base 2, and be one with couple axle 4 welderings in the perpendicular material 1, straight pin 5 passes handle 3, be fixed on behind the couple axle 4 on the handle base 2, handle 3 and couple axle 4 can rotate up and down around straight pin 5, and couple axle 4 links to each other with wire rope one end, the other end of wire rope links to each other with locking bolt, handle 3 is upwards rotated, and then couple axle 4 moves downward, and drives the locking bolt that is connected on the wire rope and moves downward, thereby lock is opened, this moment, spring was compressed, and handle 3 is unclamped, and then handle 3 is because original position is got back in action of gravity downwards, drive couple axle 4 and get back to original position, locking bolt is also got back to the state of locking under the restoring force of spring.Aforesaid handlebar unlocked mechanism is installed in the side of dodge gate at track.

As shown in figures 1 and 3, the key release mechanism is by lock 6, lock tube 7 and lock core rotating shaft 8 are formed, lock 6 is welded on the frame vertical material 1, lock tube 7 is loaded in the lock 6, and be fixed on the perpendicular material 1 with elastic cylindrical pin 9, lock core rotating shaft 8 is contained in the lock tube 7, can in lock tube 7, rotate flexibly, be provided with annular groove 10 at the middle part of lock core rotating shaft 8, on lock tube 7, be fixed with straight pin 11 and stretch in the groove 10, with the location on lock core rotating shaft 8 being carried out axially, the outer end of lock core rotating shaft 8 is square lock shaft 12, corresponding with the square opening of private key, be provided with flange 13 in the inner of lock core rotating shaft 8, be attached to the top of couple axle 4.When unblanking with private key, lock core rotating shaft 8 is rotated with flange 13, and flange 13 moves downward, and couple axle 4 is pressed down, and drives the locking bolt that is connected on the wire rope and moves downward, thereby lock is opened; Key is taken out, and then handle 3 is because original position is got back in action of gravity downwards, and couple axle 4 and locking bolt are also got back to original position automatically.Aforesaid key release mechanism is installed in the side of dodge gate in the platform direction.

In the above-described embodiments, the cross section of the lock shaft 12 of lock core rotating shaft 8 outer ends can be that other is non-circular, as triangle, polygon etc., is provided with the non-circular hole of shape unanimity therewith on private key.

On principle, the handle 3 in the foregoing description is designed to the form of left-right rotation in handle base, also can reach same purpose, and this need carry out corresponding change to the shape of handle base and couple axle.
