Abstract

The invention discloses a fire escaper. A baseplate adopts a thicker steel plate; the middle of the baseplate is bent to the shape of concave; the upper end of the baseplate is perforated; the lower end of the baseplate is perforated and circled to serve as a handle; forming holes are formed in the two sides of the baseplate; two levers, three fixed wheels and two movable wheels are formed to a locking pulley set and a speed limiting pulley set; lever positioning holes and the fixed wheels below the locking pulley set are coaxial; elliptic holes are formed in short arms of the levers, and cover end axles of the movable wheels; center shafts of the movable wheels and the fixed wheels are provided with internal threads, and are fixed at the two sides of the baseplate by screws; the end axles of the movable wheels can vertically slide in grooves; and handles are arranged at the upper ends of long arms of the levers, and are positioned by clamping rings.

Description

Life saver for conflagration

Art

The present invention relates to fire-fighting equipment, particularly life saver for conflagration.

Background technology

Along with the fast development of China's economic construction, China's cities and towns high building stands in great numbers, more in the medium-and-large-sized public welfare of fire-fighting equipment, as fire fighting truck, aerial ladder etc., the fire-fighting equipment adapting to town dweller's use is little, just in case when fire occurs, by the time fire fighter is on the scene, often causing casualties, in order to overcome the deficiency of the problems referred to above, the invention provides a kind of simple and practical life saver for conflagration.

Summary of the invention:

The technical solution adopted for the present invention to solve the technical problems is: base plate adopts comparatively steel plate centre to curve " Qian " shape, punch in upper end, handle is made in lower end punching also Volume circle, both sides are provided with shaped hole, two levers, three fixed wheels, two driving wheels, composition locking assembly pulley and speed limit pulley group, lever locating hole with locking assembly pulley below fixed wheel coaxial, lever short arm is provided with elliptical aperture, be enclosed within driving wheel end axle, driving wheel and fixed wheel central shaft are provided with internal thread, be screwed in base plate both sides, driving wheel end axle can in groove on, lower slider, the long-armed upper end of lever is provided with handle collar and locates, speed limit pulley group same method is fixed on base plate both sides, is provided with adjustment screw below driving wheel end axle, and driving wheel and forward and backward fixed wheel limit minimum clearance are equal to or slightly less than tape thickness or diameter of restricting.By threaded shown in Fig. 4 or rope, band or rope upper end are provided with hook, ring, load onto case for subsequent use with screw.

The invention has the beneficial effects as follows:

1. adopt this material of base plate to curve " Qian " shape intensity good, simple in structure and low in cost.

2. base plate upper and lower end is provided with hole of fastening the safety belt, and people can decline at random also can other people flexible and convenient operation aloft.

3. lock assembly pulley and speed limit pulley group, although driving wheel upper semi-circle all walked around by band or rope, effect is different.Front and back fixed wheel is pressed close to when locking assembly pulley driving wheel is subject to ambient pressure, pressure more kilocalorie must be tighter, band or rope are intransitable, when lever pulls to " B " direction centered by " O ", driving wheel is progressively lifted, driving wheel and fixed wheel Dwell sync strengthen, band or rope also synchronously slowly pass through, when lever overexerts to " B " direction, driving wheel and fixed wheel gap are strengthened suddenly, band or rope are for synchronously passing through rapidly under gravity, now, speed limit pulley group driving wheel is also synchronously subject to external force, driving wheel and fixed wheel setting least limit gap width are equal to or slightly less than the diameter of tape thickness or rope, under gravity, although this gap can not preventing belt or rope pass through, but resistance and frictional force are enough to buffering and inhibition zone or the speed passed through of restricting, adjustment screw is provided with below driving wheel end axle, regulate driving wheel and the optimum gap of fixed wheel, it is suitable that timely operation lever energy makes band or rope have, Negotiation speed at the uniform velocity, life safety can be guaranteed.

Detailed description of the invention:

On the basis of being processed into " Qian " shape base plate (1), locking assembly pulley (8) driving wheel fixed wheel two end axles overlaps upper lever (10) respectively, base plate (1) both sides are fastened on screw (4), speed limit wheels (5) same method is fastened on base plate (1) both sides, driving wheel can slide up and down, lever (10) is long-armed is provided with handle (13), collar (12), by figure (4) threaded or rope, there are hook, ring in band or rope upper end, load onto case (3) with screw (4).

Claims

1. a fire-fighting equipment, life saver for conflagration, by base plate, locking assembly pulley, speed limit pulley group, lever, handle, collar, case, band or rope, shackle and screw composition, it is characterized in that: base plate adopts comparatively steel plate centre to curve " Qian " shape, punch in upper end, handle is made in lower end punching also Volume circle, both sides are provided with shaped hole, two levers, three fixed wheels, two driving wheels, composition locking assembly pulley and speed limit pulley group, lever locating hole with locking assembly pulley below fixed wheel coaxial, lever short arm is provided with elliptical aperture, be enclosed within driving wheel end axle, driving wheel and fixed wheel central shaft are provided with internal thread, be screwed in base plate both sides, driving wheel end axle can in groove on, lower slider, the long-armed upper end of lever is provided with handle collar and locates.

2. life saver for conflagration according to claim 1, is characterized in that: speed limit pulley group same method is fixed on base plate both sides, is provided with adjustment screw below driving wheel end axle, and driving wheel and forward and backward fixed wheel limit minimum clearance are equal to or slightly less than tape thickness or diameter of restricting.
