The utility model discloses a directly connecting the valve threshold with the door leaf, rising the valve threshold at ordinary times, close the door leaf wartime, fall valve threshold fixed seal, the converting from wartime to peacetime production and vice versa is rapid.
Description
Technical field
The utility model relates to closed guard gate field, specifically, is related specifically to a kind of movable sill double-leaf protective sealed door.
Background technology
People's air defense is also known as civil defence, and civil defence is international word, is that government mobilizes and organizes the masses, takes anti-air strike, measure of fighting calamities and providing relief, implement rescue action, the activity of strick precaution and disaster mitigation harm.Closed guard gate belongs to civil defence safeguard, as the term suggests closed guard gate is exactly the door of people's preventive works access.
Existing closed guard gate's movable sill adopts traditional fixed form, adopts the pattern that bolt tightening is fixing, and movable sill dismounting being come at ordinary times is placed on assigned address, and wartime, bolton, easily lost at ordinary times, and converting from wartime to peacetime production and vice versa efficiency is lower.
Utility model content
The purpose of this utility model is for deficiency of the prior art, provides a kind of movable sill double-leaf protective sealed door, by directly being linked with door leaf by movable sill, at ordinary times movable sill is risen, wartime closes door leaf, and fall movable sill fixing seal, converting from wartime to peacetime production and vice versa is rapid.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of movable sill double-leaf protective sealed door, comprise power transmission shaft, bearing support is provided with at the two ends of described power transmission shaft, in the inner side of described bearing support, crank-link mechanism is installed, one end of described crank-link mechanism is connected with power transmission shaft by flat key, the other end of crank-link mechanism is provided with base, the other end of described base is connected with fork, also reversing speed variator is connected with in the end of described power transmission shaft one end, described reversing speed variator has the connecting axle axially run through, one end of described connecting axle is connected with and picks out axle, in the described periphery picking out axle, sleeve pipe is installed, the end of described sleeve pipe is provided with the first in command, the other end of described connecting axle is provided with the second in command.
Further, in described bearing support, be provided with bearing cover, and bearing support is fixedly installed in the two ends of power transmission shaft by described bearing cover.
Further, deep groove ball bearing is provided with in the junction of described sleeve pipe and the first in command.
Further, block is provided with at the top of described bearing support.
Compared with prior art, the beneficial effects of the utility model are as follows:
By directly being linked with door leaf by movable sill, risen by movable sill at ordinary times, wartime closes door leaf, and fall movable sill fixing seal, converting from wartime to peacetime production and vice versa is rapid.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of movable sill double-leaf protective sealed door described in the utility model.
Fig. 2 is the connection diagram of reversing speed variator described in the utility model.
Number in the figure illustrates: power transmission shaft 1, bearing support 2, crank-link mechanism 3, base 4, fork 5, reversing speed variator 6, connecting axle 7, pick out axle 8, sleeve pipe 9, the first in command 10, the first in command 11.
Detailed description of the invention
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the utility model further.
See Fig. 1 and Fig. 2, a kind of movable sill double-leaf protective sealed door described in the utility model, comprise power transmission shaft 1, bearing support 2 is provided with at the two ends of described power transmission shaft 1, in the inner side of described bearing support 2, crank-link mechanism 3 is installed, one end of described crank-link mechanism 3 is connected with power transmission shaft 1 by flat key, the other end of crank-link mechanism 3 is provided with base 4, the other end of described base 4 is connected with fork 5, reversing speed variator 6 is also connected with in the end of described power transmission shaft 1 one end, described reversing speed variator 6 has the connecting axle 7 axially run through, one end of described connecting axle 7 is connected with and picks out axle 8, in the described periphery picking out axle 8, sleeve pipe 9 is installed, the end of described sleeve pipe 9 is provided with the first in command 10, the other end of described connecting axle 7 is provided with the second in command 11.
Be provided with bearing cover in described bearing support 2, and bearing support 2 is fixedly installed in the two ends of power transmission shaft 1 by described bearing cover, is provided with block at the top of described bearing support 2.
Deep groove ball bearing is provided with in the junction of described sleeve pipe 9 and the first in command 10.
See table, traditional movable sill carries out improveing and is used the form of bolt tightening to be fixed on people's air defense door leaf by the utility model in traditional movable sill structure, power transmission shaft is utilized to realize the crank-link mechanism of reversing speed variator and reducer to press down and promote the movable sill of relevant position, thus achieve movable sill and promote rapidly and press down airtight function, and then reach and at ordinary times movable sill is promoted, door leaf often leaves, and facilitates personnel and equipment to pass through; Door leaf cuts out and presses down by wartime, movable sill thus reach rapidly the requirement of sealing protection.Also solve in traditional design simultaneously and movable sill will be realized linking with doorframe built-in fitting bolt, will dismantle at ordinary times and specify and preserve position (easily losing damage), movable sill and converting from wartime to peacetime production and vice versa slow shortcoming will be installed wartime.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
