Description
Technical field
The utility model relates to a kind of emergency staircase for building.
Background technology
During building operations, ladder is the instrument commonly used, in order to easy to carry; often can use by ladder, this ladder can only be against on metope, realizes climbing by a gradient; owing to being contacted by two point form with between metope, therefore, be easy to occur ladder unstable and to the situation of two Slideslips; particularly when metope smoother; and the cross section of pedal is all less, when both feet are trampled and constructed on pedal, because double-legged contact surface is less; work is not steady, and people is easy to occur rocking.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of use safety, more stable emergency staircase for building.
The utility model is achieved through the following technical solutions: a kind of emergency staircase for building, comprise two poles, the pedal of more than one is installed between two poles, pedal both sides are welded to connect with pole respectively, the upper surface of pedal arranges a slot, the front and back end of pedal respectively arranges a mounting groove, communicate between two mounting grooves, two mounting grooves communicate with slot, be positioned at slot and one pressing plate is all installed, the upper surface of described pressing plate protrudes from pedal upper surface, in described mounting groove, an extension board is all installed, the end face outside of extension board is concordant with the front/rear end of pedal respectively, the lower surface of pressing plate is arranged between two extension boards, the bottom being positioned at pressing plate is provided with first spring of more than, the lower surface of the first spring is fixedly connected with slot bottom surface, the upper surface of the first spring and the lower surface of pressing plate offset, a shoe is all installed in the upper surface of described two poles.
As preferably, described shoe comprises a fixed block and a base plate, described fixed block is fixedly installed in the top of pole, be connected by bearing pin interaction between fixed block with base plate, a cavity is offered in one side of described base plate, cavity one circle is provided with one deck soft layer, in cavity, laterally two reedings is installed.
As preferably, described reeding adopts flexible rubber material to make, and reeding is provided with anti-skidding striped.
As preferably, the cross section of described pressing plate is inverted trapezoidal shape, and the sidewall of monoblock pressing plate is an inclined plane.
As preferably, be provided with two group of second spring between described extension board and extension board, the second spring central bottom is welded on the mounting groove bottom surface of pedal inside.
The beneficial effects of the utility model are: the utility model in use, can increase the pedal cross-sectional area of operating position, so increase work time stationarity, increase safety, and the utility model also uses shoe, effectively increases the stability of ladder.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the internal construction schematic diagram of pedal in the utility model;
Fig. 3 is the bottom schematic view of shoe in the utility model;
Fig. 4 is the assembling schematic diagram between the utility model center platen and the first spring.
Coding in figure is respectively: 1 is base plate, and 2 is pole, and 3 is pedal, and 4 is pressing plate, and 5 is fixed block, and 6 is bearing pin, and 7 is cavity, and 8 is reeding, and 9 is extension board, and 10 is the first spring, and 11 is the second spring.
Detailed description of the invention
As Fig. 1, shown in Fig. 2 and Fig. 4, this emergency staircase for building, comprise two poles 2, the pedal 3 of more than one is installed between two poles 2, pedal 3 both sides are welded to connect with pole 2 respectively, the upper surface of pedal 3 arranges a slot, the front and back end of pedal 3 respectively arranges a mounting groove, communicate between two mounting grooves, two mounting grooves communicate with slot, be positioned at slot and one pressing plate 4 is all installed, the upper surface of described pressing plate 4 protrudes from pedal 3 upper surface, one extension board 9 is all installed in described mounting groove, the end face outside of extension board 9 is concordant with the front/rear end of pedal 3 respectively, the lower surface of pressing plate 4 is arranged between two extension boards 9, the bottom being positioned at pressing plate 4 is provided with first spring 10 of more than, the lower surface of the first spring 10 is fixedly connected with slot bottom surface, the upper surface of the first spring 10 and the lower surface of pressing plate 4 offset, a shoe is all installed in the upper surface of described two poles 2.
As shown in figures 1 and 3, shoe comprises fixed block 5 and a base plate 1, described fixed block 5 is fixedly installed in the top of pole 2, be connected by bearing pin 6 interaction between fixed block 5 with base plate 1, a cavity 7 is offered in one side of described base plate 1, cavity 7 one circle is provided with one deck soft layer, laterally two reedings 8 are installed in cavity 7, according to the optimum contact angle between the automatic regulating base board 1 of different gradients and metope, when soft layer compresses, reeding 8 contacts with metope, prevents the left and right transverse shifting of whole ladder.
Wherein, reeding 8 adopts flexible rubber material to make, and reeding 8 is provided with anti-skidding striped, increases frictional force.
Wherein, the cross section of pressing plate 4 is inverted trapezoidal shape, and the sidewall of monoblock pressing plate 4 is an inclined plane; Being provided with two group of second spring 11, second spring 11 central bottom between extension board 9 and extension board 9 is welded on the mounting groove bottom surface of pedal 3 inside; When both feet are trampled after on pressing plate 3, two pieces of extension boards 9 are extruded by pressing plate 4, and now the cross-sectional area of whole pedal 3 increases greatly, and after losing pedal force, two pieces of extension boards 9 playback under the effect of the second spring 11, simple and convenient.
The beneficial effects of the utility model are: the utility model in use, can increase the pedal cross-sectional area of operating position, so increase work time stationarity, increase safety, and the utility model also uses shoe, effectively increases the stability of ladder.
