Abstract

The utility model discloses a self-life-saving apparatus. Fixed pulleys which have concave arcs at outer edges thereof are arranged in a housing in an upwards and downwards support mode. An upper and a lower guiding shafts are fixed on a back plate, and a movable plate with an upper and a lower transversal runners is arranged on the guiding shafts. A front panel is supported on the movable plate, and an upper and a lower pulleys are arranged at the position between the movable plate and the front panel corresponding to the two fixed pulleys. One end of an extension spring is fixed on the side surface of the movable plate close to a life-saving rope, and the other end is fixed in the housing. A handle with a cam at the lower part thereof is arranged on the back plate, and the cam is butted to the side of the movable plate. A safety fastener capable of locking the handle is arranged on the back plate at the upper part of the handle. A threading plate capable of being threaded with a safety belt is arranged at the lower part of the housing. In emergency, people can tie the safety belt to the waist and thread the safety belt into a threading groove, and then place the life-saving rope fixed at high between the pulleys of both sides. After the safety fastener is buckled, people can rapidly slide down with the self-life-saving apparatus along the life-saving rope to achieve the goal of self-help.

Description

The self-help life-saving device

Technical field

The utility model belongs to Life Saving Apparatus, and specifically the people faces a danger in high building, can be by means of the self-help life-saving device at the own flee danger of utensil scene.

Background technology

The building that is caused by multiple reason catches fire; cause the not smooth of the stoppage in transit of elevator or passageway for fire apparatus; under the situation of the utensil of not saving oneself; people can't escape in the short time voluntarily at the utmost point that fire takes place; can only wait until that the fire fighter succours, so just need spin out the life-threatening time, and the flue gas that burning is produced is smoked that the people is unable to breath; the people is choked to death, and fire can make life moment of people loss.Fire incident takes place repeatedly in recent years, and the people's life also has been subjected to serious threat, and the people that are in eminence also can fire-cure because of can't stand flue gas, and the window from high-rise building that has jumps off, and falls to death the also not within minority of wound because of jumping out of the building.

The utility model content

Be in the problem that to save oneself when facing a danger on the high-rise for solving the people, the technical solution of the utility model is: the fixedly front and rear panel upper support in the vertical side of self-help life-saving device shell has transverse axis up and down, two fixed pulleys of outer band concave arc are separately fixed at up and down on the transverse axis, on the back plate of shell opposite side, be fixed with two guide shafts up and down, but being installed in respectively on two guide shafts of movable plate move left and right that has gliding groove transversely, on movable plate with back shaft be fixed with can with fixed front panel to together front panel, between movable plate and front panel with two fixed pulley corresponding positions up and down, be separately installed with the pulley that can move with movable plate, its outer is provided with and is same as two fixed pulleys up and down, can therewith be clipped in the concave arc of life line external diameter, one end of extension spring is fixed on movable plate on the side of life line side, and other end crosswise fixed is on its corresponding shell; The handle of bottom strap cam is installed in rotation on the back plate on extension spring top, and when the shank of handle was upwards holded up, cam was pushed the pulley on the movable plate to nearly two fixed pulley places and is clipped on the life line external diameter; The safety fastener that can pin handle is installed on the back plate; In the bottom of shell, the band plate of wearing that can wear safety belt is installed.

The utility model also has following key character:

Be processed with the speed limit tooth on the concave arc of two pulleys on two fixed pulleys and the movable plate, on the back plate below each pulley, the speed limit that the sphenocephaly subtend speed limit tooth of its upper end is installed is met and discussed;

In the lateral outer side of each pulley, the brake pad that the rear portion is fixed with spring is installed, the other end of spring is fixed on the corresponding side wall of outer shell;

Describedly be installed in wearing band plate and can swinging of brucker survival capsule bottom;

Place near the ground at life line is equipped with buffer unit.

When running into the emergency use, the life line other end that is fixed near building roof platform or window portion is put down, and on the fixing point that fixes on the ground, the people ties up to safety belt between waist rapidly, be through the brucker survival capsule bottom simultaneously and wear wearing in the trough of belt of band plate, open safety fastener, leaving behind, cam is in relaxation state behind the handle, movable plate is under the effect of extension spring, the chute which is provided with moves to the direction of leaving two fixed pulleys along guide shaft, drive front panel simultaneously and move together, making longitudinally, the both sides pulley separates; In the time of in the middle of life line is placed in the both sides pulley that separates, to push away on the handle, buckle safety fastener and make the handle location, this moment, cam overcame the pulling force of extension spring, the pushing movable plate relies on the life line direction, two pulleys up and down on the movable plate and two fixed pulleys up and down of a side are clipped on the life line external diameter, front panel and be close together simultaneously with the fixed front panel of shell disjunctor, the people can slide rapidly along life line with brucker survival capsule and reach the purpose of saving oneself, many life line can make a plurality of people slide simultaneously, also can be that a plurality of people's spacers are from sliding at same life line; When not using, many life lines are folded respectively leave in as not taking up space in the wall hole of putting fire-fighting equipment, during use fag end is got rid of down, as long as the someone fixes below, or it is fixing when urgent, use the deceleration tooth and the speed limit of processing on the concave arc of wheel outer to meet and discuss, and in the outside on two-wheeled edge brake pad is housed, people's downslide just can be controlled to inoffensive speed; If at the place near the ground of life line buffer unit is installed, it will be safer sliding to ground under the people.

If wear band plate and can swing, because the effect of body weight, tie up to safety belt between waist and will make the people be in comfort conditions all the time perpendicular to ground.
