Abstract

The utility model discloses a miniature life-saving means for people from high buildings which is designed by a simple mechanical principle. The utility model is composed of a handle, a bracket, a pulley, a steel cable, a cam disk, a lug, a speed limiting slide block of which the center is provided with a recess, etc. When used, the steel cable only needs to be fixed and hung, and people or objects are tied to one end of the handle; when the utility model descends, the pulley is driven to rotate by the steel cable, and the lug is driven to do circumferential movement by the cam disk. The limiting slide block limited by the bracket edge can only do reciprocating movement from the top down. Thus, the rotating speed of the cam disk is effectively limited; people or objects can descend at a slow speed, and then the life-saving purpose is obtained.

Description

Miniature high-building life-saving device

The utility model relates to the lifesaving apparatus, a kind of specifically brucker survival capsule of miniature high building automatic speed-limiting.

The reform and opening-up of China has been brought huge variation to society, and high buildings and large mansions in all parts of the country are rised sheer from level ground like the mushrooms after rain.Along with the continuous increase of high building, the high-rise building fire prevention has become an important problem with lifesaving.High building bottom breaking out of fire at present can only lean on fire department to rescue the people with high-rise stair.But the height of stair is extremely limited, and it is also slow to rescue people's speed, does not therefore fit into current needs.

In order to address this problem, there is the people to utilize long cloth bag that a kind of hard cloth makes in the Chinese patent as brucker survival capsule, one of its strap is fixed on upstairs, and the other end is from upstairs throwing away on the ground, and the people slides from cloth bag.It is long more to implement its cloth bag of lifesaving in this way, and volume is just big more, and the scope that can only accomplish three, four floors, otherwise a people is by can't move.Therefore, be subjected to the restriction of building level, each position and the length weight of cloth bag own, be difficult to play one's part to the full.

The purpose of this utility model be to provide a kind of, simple in structure, volume is little and mechanical miniature high-building life-saving device that can automatic speed-limiting.

The purpose of this utility model is to realize like this; A kind of miniature brucker survival capsule of being made up of cam disc, projection, speed limit slide block and steel wire rope etc. is characterized in that; By a handle, the two ends of handle are fixed with support, and two stands is inserted with a main shaft by the center of lower end is horizontal, is with a rope sheave on the main shaft, and volume has steel wire rope on the rope sheave; Two of rope sheave is cam disc and vertical driving wheel, is fixed with the projection of five equilibrium on the cam disc; Main shaft has the speed limit slide block of groove in the middle of also being with on the end face of emersion cam disc, speed limit slide block intermediate groove matches with the edge of support.Need only during use steel wire rope is hooked on the object that can bear the human body body weight, the staff handle of holding just can leave the underfooting strong point, directly down jump, steel wire rope promptly can drive rope sheave and roll, along with also just driving projection, the roll cam dish of rope sheave rolls doing circumference, be enclosed within the speed limit slide block of cam disc end face like this, promptly can be along with rotation, do to pump along support.Therefore the speed limit slide block just can limit the quick rotation of cam disc effectively, thereby plays the purpose that speed limit descends.

The utility model is because fixed the projection of five equilibrium on cam disc, the speed limit slide block that utilizes the cam disc end face to be enclosed within on the main shaft simultaneously is mated, like this when cam disc is done the circumference rotation, the speed limit slide block can only pump doing under the edge limitation of support, therefore thereby the quick rotation that has stoped projection can play the purpose of speed limit effectively.The utility model utilizes handle to make the people can conveniently catch it simultaneously, and can be provided with waistband hole etc. under the handle, can utilize waistband to be enclosed within safely on the person, can tie object again and make it hang onto ground lentamente from eminence.

Concrete structure of the present utility model is provided by following examples and illustration thereof.

Fig. 1 is the utility model surface structure stereogram.

Fig. 2 is the utility model cam disc and the view that cooperates of limited block.

By a handle (1), the two ends of handle (1) are fixed with support (2) among the figure, and two stands is with a rope sheave (11) by the horizontal main shaft (9) that is inserted with in center of lower end on the main shaft (9), and rope sheave (11) is gone up volume steel wire rope (6); Two of rope sheave (11) is cam disc (3) and vertical driving wheel (7), is fixed with the projection of 3 to 25 five equilibriums on the cam disc (3); Main shaft (9) has the speed limit slide block (10) of groove in the middle of also being with on the end face of emersion cam disc (3), speed limit slide block (10) intermediate groove matches with the edge of support (2).As long as steel wire rope is hung up properly, people or object promptly can utilize handle during use, have realized the purpose of speed limit decline.

Claims

1, a kind of miniature high-building life-saving device of being made up of cam disc, projection, speed limit slide block and steel wire rope etc. is characterized in that being; By a handle (1), the two ends of handle (1) are fixed with support (2), and two stands is with a rope sheave (11) by the horizontal main shaft (9) that is inserted with in center of lower end on the main shaft (9), and rope sheave (11) is gone up volume steel wire rope (6); Two of rope sheave (11) is cam disc (3) and vertical driving wheel (7), is fixed with projection (4) on the cam disc (3); Main shaft (9) also is with speed limit slide block (10) on an end face of emersion cam disc (3).

2, miniature high-building life-saving device according to claim 1 is characterized in that the projection (4) that 3 to 25 five equilibriums are arranged that cam disc (3) is upward fixing.

3, miniature high-building life-saving device according to claim 1 is characterized in that having groove in the middle of the speed limit slide block (10).
