Abstract

The utility model discloses a multifunctional lifesaving descent control device, which is characterized in that an upper slot wheel(2) and a lower slot wheel(14) are fixed between two structure boards(1),(12), the lower parts of the structure boards(1),(12) are provided with a flying ring screw combination(4), the lower part of a flying ring(5) is fixed with a safe belt(6), a descent control metal rope(10) whose upper side is provided with a metal hook(11) winds from the left side of an adjusting screw rod combination(9) from top to bottom, winds the upper slot wheel(14) from the right side of the upper slot wheel(2) and then winds to the left side and freely downward moves from the left side of the upper slot wheel(2). The utility model has a simple structure, which is small, smart, light and convenient, can be paused during the declining course. Rope of the utility model is uneasy to be burned out. With low manufacture cost, the utility model not only can be used for the escape in a building fire scene, but is suitable for the military police to carry out a special task or save a life.

Description

Multifunctional escaping descent control device

Technical field

The utility model relates to a kind of multifunctional escaping descent control device, especially a kind ofly not only can be used for from the on-the-spot escape of fire in high buildings but also can be used for the multi-functional descending lifeline that army and police security personnel carries out special duty.

Background technology

The existing high building escaping descent control device that catches fire, complex structure, heaviness, valency is expensive, carries inconvenience, and the not good and old weak person's inconvenience of muscle power is used, and can not suspend in landing midway, brings many obstacles thereby give to apply.

The utility model content

The purpose of this utility model is to overcome the above-mentioned defective of existing escaping descent control device, provide a kind of simple in structure, small volume and less weight, landing can suspend in the way, used rope is difficult for being burnt disconnected, manufacturing cost is lower, both can be used for the scene of fire escape, can be used for the multifunctional escaping descent control device that army and police carry out special duty again.

The technical solution of the utility model is: upper and lower two sheaves are fixed between two structural slabs; Two structural slab tops, one side should be provided with regulating tank, install to regulate the combination of sieve bar in the regulating tank, also can not establish regulating tank and is provided with fixedly that sieve bar makes up; The combination of suspension ring sieve bar is set in two structural slab bottoms, and one pair of safety belt is fixed in the suspension ring bottom, also should adorn one pair on safety belt top and have the secondary safety belt that the double square ring has non-return effect; The upper end is equipped with the slow of metal hook and is fallen metallic cable from top to bottom, had mercy on from sieve bar combination left side, the sheave down of having mercy on downwards through last sheave right side, more upwards by the right side of last sheave around downwards free to the left.The slow metal hook that falls the metallic cable upper end can be the survivor of a murder attempt, can not be the survivor of a murder attempt also.Metallic cable can adopt naked steel wire rope, and the fire-retardant chemical fibre of outsourcing, cotton cord or multiply chemical fibre steel core rope also can adopt other metallic cables.

The utility model is simple in structure, small volume and less weight, and used rope can not burnt disconnected, and landing can suspend in the way, both can be used for the on-the-spot escape of fire hazard of storied house, brings convenience for army and police carry out special duty again, and manufacturing cost is also lower.

Description of drawings

Fig. 1 is the utility model front view;

Fig. 2 is the utility model side view;

Fig. 3 reaches sheave part front longitudinal sectional view up and down for the utility model structural slab.

The specific embodiment

Below in conjunction with accompanying drawing an embodiment of the present utility model is illustrated.

Referring to accompanying drawing 1 and accompanying drawing 2, to go up

sheave

2 and 4 rivets 3 of following sheave 14 usefulness is riveted between pre-structure plate 1 and the back structural slab 12, upper right quarter at pre-structure plate 1 and back structural slab 12 has adjusting slotted eye 15, regulating sieve bar combination 9 crosses in regulating slotted eye 15, suspension ring sieve bar makes up 4 crosswise fixed in two structure plates bottoms, and pass suspension ring 5, fix one pair of safety belt 6 in suspension ring 5 bottoms, and one pair of secondary safety belt 8 that has double square ring 7 is housed on safety belt 6 tops, slowly fall steel core rope 10 upper ends survivor of a murder attempt's metal hook 11 is housed.

Can see that by Fig. 3 steel core rope 10 was from top to bottom had mercy on from the left side of regulating sieve bar combination 9, sheave 2 right sides on process, the sheave 14 down of having mercy on downwards, again by the right side of last sheave 2 around free to the left downward.

Using method is as follows: survivor of a murder attempt's metal hook 11 is hooked in the place that window or balcony top or other any places can the hook jails, perhaps steel core rope 10 is wrapped on the firm object in any place, and hook steel core rope 10 with survivor of a murder attempt's metal hook 11, the descender is enclosed within safety belt 6 under the both arms, both feet are stepped out outside window, and catch the bottom of steel core rope 10 slowly to loosen gently by a hand or both hands, human body just can be by the hand loosening up speed control decrease speed of catching steel core rope 10, when the too fast needs that descend stop, the bottom of steel core rope 10 can be wrapped on the health arbitrarily or safety belt 6, or on the suspension ring 5; Also can be sitting in the middle of the safety belt 6, and secondary safety belt 8 is enwinded health, secondary safety belt be worn in double square ring 7 strained, like this, can convenient army and police when utilizing this utensil to carry out special duty, be parked in needed position liberation both hands, armed strike enemy; Perhaps both hands are embraced the person's of remaining unconscious escape.

Slow operation principle of falling is: because steel core rope 10 upper ends are fixing, human body forms a pulling force below this utensil, the steel core rope is tightened up, at this moment, steel core rope 10 forms bigger frictional force between last sheave 2 and following sheave 14, force human body can not descend rapidly, and steel core rope 10 has further strengthened frictional force in the phase mutual friction again of last sheave 2 right sides.The adjusting sieve bar that can adjust the up and down combination 9 that is provided with in the upper right side of last sheave 2, can be according to the distance of human body weight up-down adjustment steel core rope 10 and last sheave 2 in regulating tank 15: regulate downwards, steel core rope 10 dwindles with the distance of last sheave 2, and the two mutual frictional force increases; Otherwise to adjusted, the two is apart from increase, and frictional force reduces mutually.
