Abstract
The utility model relates to a locking mechanism, in particular to a locking mechanism for a protective airtight partitioning door for metro sections, which comprises a protective door frame. A gate is disposed in the protective door frame, a vertical screw rod is arranged in the gate and penetrates through a worm reducer to be meshed with the worm reducer, a hand wheel is arranged on the worm reducer, two ends of the vertical screw rod are respectively connected with a horizontal connecting rod through tumblers, a connecting plate is fixed at the outer end of the horizontal connecting rod, and a horizontal lock is fixed on the connecting plate and inserted into the protective door frame. The locking mechanism for the protective airtight partitioning door for metro sections is simple in structure, high in closeness, convenient to operate and long in service life and improves safety.
Description
Technical field
The utility model patent relates to a kind of blocking mechanism, relates in particular to a kind of blocking mechanism that is used for the interval airtight partition door of protection of subway.
Background technology
Switching mechanism in the airtight partition door of present protection of the prior art, complex structure, and also the protection seal is poor, can not stop toxic gas to penetrate into engineering inside, and a little less than the wave energy of the shock resistance simultaneously power, it is slow to open speed, and influence is used normally.
Chinese patent CN201020014706.0 discloses a kind of ascending/decending subway partition door, comprises door leaf, also comprises the lifting seat that is positioned at door leaf top and is positioned at lifting seat below and upper end and is installed in the vertical shaft on the lifting seat; One side of described door leaf is connected with vertical shaft through hinged slide mechanism; On the lifting seat, fixed pulley is installed, wire rope the inner of walking around described fixed pulley is connected with door leaf, and the outer end is connected with actuating unit.Though this structure is simple, seal is poor, does not have the effect of protection.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the prior art, provides a kind of simple in structure, and easy to operate, and seal is high simultaneously, and the blocking mechanism of airtight partition door is protected in safe being used to.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of blocking mechanism that is used to protect airtight partition door; Comprise the protection doorframe, be provided with the gate in the described protection doorframe, be provided with vertical screw mandrel in the described gate; Described vertical screw mandrel cross-under is crossed worm reducer and is meshed; Described worm reducer is provided with handwheel, and the two ends of described vertical screw mandrel are connected with transverse link respectively through pivoted arm, and the outer end of described transverse link is fixed with junction plate; Be fixed with horizontal tapered end on the described junction plate, described horizontal tapered end is inserted in the protection doorframe.
Protect airtight partition door,, protect airtight requirement height, 14 horizontal tapered ends must be installed on door leaf, to guarantee stoping toxic gas to infiltrate the inner and shock resistance wave energy power of engineering because the door leaf area is big.Accomplish 14 locking heads with a cover blocking mechanism and locked door leaf simultaneously.
Operating principle:
Rotate the handwheel on the worm reducer; Make vertical screw mandrel do upper and lower vertically moving, drive upper and lower two pairs of pivoted arms and do 90 ° of rotations, make transverse link do side-to-side movement; Thereby drive left and right two junction plates, make the horizontal tapered end that is assemblied on the junction plate do left and right moving.Go up vertical tapered end and move up and down, reach 14 tapered ends and fasten door leaf simultaneously, realize converting from wartime to peacetime production and vice versa " quick, flexible " requirement.
As preferably, the top and bottom in the described gate are respectively equipped with transverse link, and described longitudinal rod is connected to a fixed through doubly-linked joint and pivoted arm.
As preferably, the top and bottom of described vertical screw mandrel are connected to a fixed with the gate through the solid page or leaf of screw mandrel respectively, and described transverse link is connected to a fixed with the gate through the solid page or leaf of connecting rod.
As preferably, be provided with 6 horizontal tapered ends on the described junction plate uniformly, described horizontal tapered end is provided with the solid page or leaf of tapered end, and the solid page or leaf of described tapered end is connected to a fixed with the gate.
Therefore, the blocking mechanism that is used to protect airtight partition door of the utility model, simple in structure, seal is high, and is easy to operate, and long service life improves safety.
