Description

Technical Field

[0001] The invention relates to the field of security products, and in particular to a folding room type multi-person speed-controlled escape device. Background Art

[0002] The biggest worry for buildings is that it is difficult to escape in case of fire, especially for the elderly, weak, sick, disabled, children, and women, who have specific factors that make it more difficult to escape. In some large buildings, such as high-rise buildings, large shopping malls, hospitals, etc., the internal structure is intricate. There are many passages, stairs, and emergency exits. People can easily get lost in the event of a fire. Escaping from the inside of the corridor will waste precious escape time. For buildings with larger areas, the distance from certain locations inside the building to the emergency exit may be very far. The speed of fire development is very fast, especially in an environment with flammable materials. High temperature and flames will quickly block the escape passage, making it difficult for people to pass through. Some people, such as the elderly, disabled, and children, will encounter greater difficulties in escaping due to physical reasons. The elderly are slow in movement and may not be able to escape from the fire scene quickly; disabled people may not be able to use escape facilities such as stairs independently due to physical disabilities; children may be unable to respond to the fire correctly because of panic.

[0003] In view of the above problems, an escape device is needed. In the prior art, some escape devices have complex structures and are inconvenient to operate. Such escape devices may waste precious time due to operational errors in emergency situations; some escape devices are unsafe in design and cannot withstand the weight of multiple people using them at the same time. In emergency situations such as fire, there may be safety hazards such as breakage and deformation; some escape devices only have one safety protection mechanism, lack basic speed control functions, and are not equipped with anti-fall devices or overload protection devices.

[0004] Although the prior art such as CN110478635A discloses a fire escape lifting bag, it only has a safety protection mechanism and lacks a fall prevention device and an overload protection device. Moreover, the prior art can only be used by one person at a time and cannot carry and take care of special groups such as the elderly, the weak, the sick, the disabled, children, and women. In the event of chaos on the scene, it may not be possible to take care of every special group in time. Summary of the invention

The weight adjustment button 19 controls the rotation position of the expansion brake clutch rod 8 around the length of the gate line 12. The left speed control handle 35 can control the full rotation of the expansion brake clutch rod 8 through the gate line 12. When the product leaves the factory, the weight adjustment button 19 is at a position of about 80 pounds, that is, the speed of the escapee weighing about 80 pounds is about 1.2 seconds per meter. When the total weight of the escapee is about 260 pounds, the pointer of the weight adjustment button 19 is turned to the 260-pound position. At this time, the escapee runs at a speed of about 1.2 seconds per meter. When the speed is too fast, the left speed control handle 35 is held to increase the force to slow down, and the greater the force, the slower the speed until it stops. The left side only turns the weight adjustment knob 19 to the corresponding marked position according to the approximate weight of all persons when in use. There is no need to use the left speed control handle 35 in case of emergency.

[0100] The right side of this embodiment is in a braking state when it is in standby mode. When the escapee enters the escape device and stabilizes it, the stabilizing switch 10 is loosened. At this time, the escape device is in a static braking state. The master controller holds the right speed control handle 36 and slowly applies force. The escape device moves slowly. The greater the force applied, the faster the speed. If no force is applied, the escape device will not move. The working principle is: the expansion brake 6 controls the operation of the shaft wheel 3, the expansion brake clutch rod 8 controls the opening and closing of the expansion brake 6, and the pull spring 21 and the expansion spring 22 work together to push and pull the expansion brake clutch rod 8 to a state where the expansion brake 6 can stop the shaft wheel 3. Only when the master controller holds the right speed control handle 36 and applies force, pulls back the expansion brake clutch rod 8 through the gate line 12, and relaxes the control of the expansion brake clutch rod 8 on the expansion brake 6, the shaft wheel 3 can rotate, and the whole can move downward. The greater the force applied to the right speed control handle 36, the faster the overall running speed. If the hand is released and no force is applied, the escape device will not move.

[0101] The specific operation method of this embodiment is as follows:

[0102] The escape device is a device that accompanies the escapee when in use. When in use, first unfold the escape device protective cover 31, screw on the rope outlet tube 16, hang the protective cover 31 on the protective cover hanging ring 18, screw the weight adjustment button 19 to the corresponding marked position according to the approximate total weight of all people, and hook the fixing hook 32 on the pre-set fixing ring or a fixable object.

[0103] Move the escape device out of the window, adjust the height of the escape device to the same level as the window sill through the manual rope wheel 33, turn off the stabilizing switch 10, and the escape device is stable and immovable. The host first enters the escape device protective cover 31 and places the rope tube 16 between the legs. Put the legs into the trouser legs 30 and sit on the host 1 and the soft chair 24, and fix the host's chest to the rope tube 16 with the leg fixing belt 23, waist belt 25, and shoulder belt 26. Others will successively put on the safety belts, hang them on the multi-person hanging ring 17, enter the protective cover 31, and the escapee's legs will be put into the trouser legs 30 to stand on the left and right and behind the host, and fasten the tether 29.

[0104] The following is operated by the master

[0105] The first step is to unscrew the valve of the high-pressure gas storage device 34 to fill the high-pressure gas into the double-layer compartment of the protective cover 31;

[0106] Step 2: Loosen the stabilizing switch 10;

[0107] Step 3: Hold the rope outlet tube 16 with both hands, hold the speed control handle 15 with your fingers, and slowly apply force to the right speed control handle 36 with your right hand. At this time, the whole will go from static to slow. The speed of the descent depends on the strength of the right hand. The greater the force, the faster the speed. However, the fastest descent speed is limited. The deceleration device in the rope outlet seat 13 and the total weight adjustment button 19 on the left side are used to ensure safety. If the force is small, the speed is slow, and if the force is large, the speed is fast. If no force is applied, the escape device will stop. The left speed control handle 35 held by the left hand is set to prevent accidents. It does not need to be used under normal circumstances. In case of emergency, the grip can be strengthened to make the escape device slow down and then stop after applying force. During operation, the main controller can understand the running speed and the outside situation through the observation hole 27, put the feet into the trouser legs 30 to adjust the position, control the speed through the right speed control handle 36 held by the right hand, slow down when approaching the ground, and land smoothly.
