Abstract
The invention relates to a public plate safety device, in particular to a lifting type tread-preventing device. The device comprises fixed supports, clamps, inner telescopic rods and a pair of handrail rods, wherein multiple inner telescopic rods are installed on each handrail rod and hinged to the fixed supports, the fixed supports and the clamps are fixed to the top of a stairway, the handrail rods are installed parallel to the stairway, the handrail rods and the inner telescopic rods are overturned to be attached to the top of the stairway when not used, and the handrail rods are clamped by the clamps. The device can be stored on the top of the stairway, the free height and appearance of the stairway are not affected, and the handrail rods can provide leverage points for escape crowd to main body balance after descending; meanwhile, the two handrail rods are combined with stair railings after descending, and crowd decentralization can be guided, so that people can be evacuated in order.
Description
Technical field
The present invention relates to a kind of public place safety device, specially lifting type are anti-to trample device.
Background technology
Existing patent《Handle type stair special for preventing trampling accidents》(application number：201110270393.4) describe a kind of energy
In case of emergency prevent the equipment for trampling accident, it is to be provided with three suspensions along stair longitudinal direction in the bottom of stair bench
Bar, arranges handle in every hanger bar, each handle is 1.7-1.9 rice with the vertical distance of ladder step below, is in pedestrian
In the case of falling, the handle of top can be caught, so as to avoid the accident of trampling caused because of tumble from occurring.The technical disadvantages
It is mainly manifested in：(1) its design be at ordinary times always fixation hang on above stair, handle with below ladder step it is vertical away from
From for 1.7-1.9 rice, current to crowd under nonemergency can impact, not only affect the head room of stair passage and outer
See, and change the 26S Proteasome Structure and Function of building；(2) handle is located near the escape crowd crown, and at regular intervals between shaking hands,
It cannot be guaranteed that unbalanced people can catch handle, facility can be affected to prevent trampling effect, because it is in nonemergency design
Defect, it is difficult to popularization and application.
The content of the invention
For above-mentioned technical problem, the present invention provide it is a kind of can receive it is anti-trample device, do not affect under normal circumstances
Crowd's is current.Specifically technical scheme is：
Lifting type is anti-to trample device, including hold-down support, fixture, interior expansion link and a pair of handrails, and each described is helped
Multiple interior expansion links are installed, described interior expansion link is hinged on hold-down support, and hold-down support and fixture are fixed on building on bar
Ladder access top top, a pair of handrails along the parallel installation in stair road, handrail and interior expansion link do not use when, upset be attached to stair
The top top in road, by fixture handrail is clamped.
Described interior expansion link is made up of Multi section bar, and there is respectively packing ring two pole junctions of bottom, is pacified between packing ring
Equipped with spring.
The lifting type that the present invention is provided is prevented trampling device, and the top top in stair road, Bu Huiying can be accommodated at ordinary times
The head room and outward appearance of stair are rung, can be connected with fire alarm, key triggering；Handrail can be provided after declining for escape crowd
Maintain balance by means of force, meanwhile, two groups of handrails are combined after declining with banister, can guide crowd decentralization, are removed in order
From.Handrail height adjustable, can adjust the falling head of interior expansion link and handrail, the scope of application according to different occasion personnel situations
Extensively.
Description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the side block diagram in emergency circumstances of the present invention.
Specific embodiment
The specific embodiment of the invention is described with reference to the drawings, as depicted in figs. 1 and 2, lifting type is anti-to trample device, including
Hold-down support 2, fixture 4, interior expansion link 3 and a pair of handrails 1, on each described handrail 1 multiple interior expansion links 3, institute are provided with
The interior expansion link 3 stated is hinged on hold-down support 2, and hold-down support 2 and fixture 4 are fixed on the top top in stair road, is helped for a pair
Bar 1 along the parallel installation in stair road, handrail 1 and interior expansion link 3 do not use when, upset is attached to the top top in stair road, by pressing from both sides
Tool 4 clamps handrail 1.
Interior expansion link 3 is made up of Multi section bar, and there is respectively packing ring two pole junctions of bottom, and bullet is provided between packing ring
Spring, prevents whereabouts from injuring crowd by a crashing object.
Under nonemergency, interior expansion link 3 shrinks, and handrail 1 and interior expansion link 3 pack up the top top for being attached to stair road,
And handrail 1 is fixed by fixture；In emergency circumstances, operator's trigger switch, fixture 4 is opened, and handrail 1 is with interior expansion link 3 in weight
Plumbness is turned under power effect, it is 1.0-1.5 that interior expansion link 3 is elongated under gravity away from lower section stair vertical dimension
Rice position, escape crowd can hold handrail 1 and prevent from falling.
In order to prevent interior expansion link 3 and handrail 1 from injuring escape crowd by a crashing object during decline, in last two section of interior expansion link
Seam arranges packing ring with spring to reduce decrease speed.
