Description
Technical field
A kind of switching mechanism, more particularly to a kind of people's air defense closed beam switching mechanism are the utility model is related to, belongs to people's civil defence
The production installing area of empty special equipment.
Background technology
Closed guard gate is arranged on each personnel and the vehicle in and out port of civil air defense projects, is as civil air defense projects oral area
The important component of protection, vital effect is played in wartime.And closed guard gate is usually intended only as personnel and vehicle
Gateway, in order to not influence the discrepancy of personnel and vehicle, movable sill typically can be all set in closed guard gate bottom, usually by movable sill
Move ad-hoc location after removing to be placed, movable sill is carried to come to be installed by wartime again.And due to movable sill weight compared with
Weight, need to be equipped with special equipment and professional during carrying, there is that troublesome in poeration, use cost is high, the converting from wartime to peacetime production and vice versa time
The shortcomings that length peace war conversion efficiency is low.
Utility model content
In view of the above-mentioned problems, the problem of the utility model intends to solve be to provide it is a kind of simple and reasonable, easy to use fast
Prompt and low use cost people's air defense closed beam switching mechanism, can not only be rapidly completed converting from wartime to peacetime production and vice versa, greatly improve converting from wartime to peacetime production and vice versa
Efficiency, shorten the converting from wartime to peacetime production and vice versa time, and the bottom surface utilization rate of air-raid shelter can be improved.
To reach above-mentioned purpose, the utility model uses following technical scheme：A kind of people's air defense closed beam switching mechanism, including
Commutator, pick out axle, inner handle, outdoor handle, sleeve pipe, power transmission shaft, bearing block, crank, connecting rod, rocking bar and base, the commutation
Device one end is connected with inner handle, and the other end is connected with one and picks out axle, and described pick out is connected with an outdoor handle on the axle other end, described
Pick out and sleeve is arranged with axle, a power transmission shaft is also equipped with the commutator, the power transmission shaft is fixed on by bearing block
On the commutator, a crank is also arranged with the power transmission shaft, a connecting rod, the connecting rod other end are connected with the crank
On be connected with a rocking bar, a base is connected with the rocking bar.
Preferably, the connecting rod two end and the connector of the crank and the rocking bar are bearing pin.
Effective achievement of the present utility model：The utility model is simple and reasonable, in use, being set on closed guard gate's door leaf
Pass through aperture, outdoor handle is pulled down, then commutator is fixed on closed guard gate's door leaf, made to pick out axle one end and pass through closed guard gate's door leaf
On through hole, and stretch out outside the through hole, now install outdoor handle on the end for picking out axle, then by bearing block and bottom
Seat is each attached on closed guard gate's door leaf, and rocking bar is welded on closed beam, and closed beam is arranged on closed guard gate's door leaf and lower door frame
Between junction.As long as finally by manipulating inner handle and outdoor handle, you can the upset to closed beam is easily accomplished, it is usually complete
Complete not influence the current of personnel and vehicle, wartime can be rapidly completed converting from wartime to peacetime production and vice versa, it is not necessary to carry out carrying peace to movable sill again
Dress, there is the characteristics of easy to operate, use cost is low, not only greatly improve converting from wartime to peacetime production and vice versa efficiency, when shortening converting from wartime to peacetime production and vice versa
Between, and the bottom surface utilization rate of air-raid shelter can be improved.
