Description
Technical field
The present invention relates to sliding door unlocking mechanism field, more particularly to a kind of rail traffic sliding door manual unlocking device.
Background technology
At present, track traffic is that solve the most important means of urban congestion, and track traffic has that freight volume is big, speed is fast, accurate
Point, environmental protection, save the advantages such as the energy.Because flow of the people is excessive, the safety of subway is particularly important, often in platform
Safety door is provided between track, platform and track are separated, prevents passenger to be strayed into the danger zone around track.General feelings
Under condition, safety door is all by Electric automatic control, and when power supply or control system break down, safety door can not automatically open up,
At this moment manually opened safety door is just needed.Existing hand-operating unlocking mechanism structure is complex, and transitional movement is too many, easily occurs
Failure.
The content of the invention
In order to solve the above problems, the present invention proposes that a kind of rail traffic sliding door simple in construction, that reliability is high is manual
Tripper.
Specifically, a kind of rail traffic sliding door manual unlocking device, including sliding door, release lever, drive link, ejection
Connecting lever, retaining mechanism, described retaining mechanism include sleeve, lock core, return unit and block, and described release lever is hinged on cunning
The side of dynamic door, the hinged place of release lever are fixedly connected with one end of the abutting stem, and the other end of abutting stem is hinged with biography
Lever, the free end of drive link are hinged with ejection connecting lever, and the ejection connecting lever is chevron, and the corner of the chevron is articulated with cunning
Dynamic door；Described block is fixedly mounted on the top of affixed side box, and block side is provided with sleeve, and the bottom plate of sleeve is provided with square
Hole, described lock core are fixedly connected with the return unit, and lock core passes through the square opening, return unit lower surface and set tube end plate
Upper surface is in contact, and is provided with longitudinal guide runner on the block side of the close lock core, and lock core is provided with leading of being adapted
Rail；Key switch is provided with the sliding door of the release lever offside, key switch is consolidated by connector and the abutting stem
Fixed connection.
The minimum point of the ejection free endvertex of connecting lever and the lock core under free state is on same horizontal plane.
Described connector includes cross bar and L-shaped bar, and described cross bar is fixed on abutting stem, and cross bar is perpendicular to slip
Door, the free end of the cross bar are connected with L-shaped bar, and the other end of L-shaped bar is connected with key switch.
Described return unit is spring.
The section of described lock core is square, and top is provided with chamfering.
Described slide guide slot cross-section is trapezoidal.
The beneficial effects of the present invention are：The action of unblock is only completed with drive link and ejection connecting lever, reduces device
Unnecessary transitional movement, it is relatively simple for structure, add the reliability of device；The setting of block guide runner and lock core guide rail, increase
The stability of lock core is added, has made structure more reasonable.
Brief description of the drawings
Fig. 1 is the structural representation of rail traffic sliding door manual unlocking device；
1- sliding doors, 2- release levers, 3- drive links, 4- ejections connecting lever, 5- sleeves, 6- lock cores, 7- return units, 8- gears in figure
Block, 9- abutting stems, 10- affixed side boxes.
Embodiment
In order to which technical characteristic, purpose and the effect of the present invention is more clearly understood, now control illustrates this hair
Bright embodiment.
As shown in figure 1, a kind of rail traffic sliding door manual unlocking device, including sliding door 1, release lever 2, drive link
3rd, connecting lever 4, retaining mechanism are ejected, described retaining mechanism includes sleeve 5, lock core 6, return unit 7 and block 8, described unblock
Handle 2 is hinged on the side of sliding door 1, and the hinged place of release lever 2 is fixedly connected with one end of the abutting stem 9, abutting stem 9
The other end be hinged with drive link 3, the free end of drive link 3 is hinged with ejection connecting lever 4, and the ejection connecting lever 4 is chevron, the V
The corner of shape part is articulated with sliding door 1；Described block 8 is fixedly mounted on the top of affixed side box 10, and the side of block 8 is set
There is sleeve 5, the bottom plate of sleeve 5 is provided with square opening, and described lock core 6 is fixedly connected with the return unit 7, and lock core 6 is described in
Square opening, the lower surface of return unit 7 are in contact with the upper surface of the bottom plate of sleeve 5, are set on the side of block 8 of the close lock core 6
There is longitudinal guide runner, lock core 6 is provided with the guide rail being adapted；Key is provided with the sliding door 1 of the offside of release lever 2
Switch, key switch are fixedly connected by connector with the abutting stem 9.
As shown in figure 1, it is described ejection 4 free endvertex of connecting lever and the lock core 6 under free state minimum point be in it is same
On individual horizontal plane.Described connector includes cross bar and L-shaped bar, and described cross bar is fixed on abutting stem 9, and cross bar perpendicular to
