下面结合实施例附图进一步说明本实用新型的技术方案。 The technical scheme of the present utility model is further described below with reference to the accompanying drawings of the embodiments.

参见图 1并结合参见图 ' 2, 图 1中示意出高层建筑自身救生器的主要绪构，图 2中示意出其右侧板上刹车机构的结构。 Referring to FIG. 1 in combination with FIG. 2, FIG. 1 illustrates a main structure of a lifesaving device of a high-rise building, and FIG. 2 illustrates a structure of a braking mechanism on a right side plate thereof.

由两块侧板 15和固定在两侧板 15上的三根固定杆 12构成支架，固定杆 12支撑两侧板 15, 而形成一个空间，供装配连接轴转动机构与缆绳收放机构。挂环 3套设在位于救生器下部的固定杆 12上，供勾扣安全带。 A bracket is formed by two side plates 15 and three fixing rods 12 fixed on the side plates 15, and the fixing rods 12 support the side plates 15 to form a space for assembling the connecting shaft rotation mechanism and the cable retracting mechanism. The hanging ring 3 is set on the fixing rod 12 located at the lower part of the lifeguard, and is used for hooking the safety belt.

连接轴转动机构包括连接轴 13、固定在连接轴 13上的摇把 8和刹车机构。刹车机构包括斜齿轮 6、两片摩擦片 7、两片垫片 5和两个棘爪 4 (带有弹簧，图中未示出）。连接轴 13定位在两侧板 15间，摇把 8 固定在连接轴 13—端并位于一侧板 15外，该端连接轴 13上按一垫片 5、一摩擦片 7、斜齿轮 6、一摩擦片 7、一垫片 5的顺序固定上述部件，两个棘爪 4固定在该侧侧板上，并与斜齿轮 6上斜齿咬合，如图中所示仅允许斜齿轮 6往图示方向转动 (顺时针方向）。 The connecting shaft rotating mechanism includes a connecting shaft 13, a handle 8 fixed on the connecting shaft 13, and a brake mechanism. The braking mechanism includes a helical gear 6, two friction plates 7, two pads 5, and two pawls 4 (with springs, not shown in the figure). The connecting shaft 13 is positioned between the two side plates 15, and the rocker 8 is fixed at the end of the connecting shaft 13 and is located outside the one side plate 15. The end of the connecting shaft 13 presses a washer 5, a friction plate 7, a helical gear 6, A friction plate 7 and a washer 5 fix the above components in order, two Each pawl 4 is fixed on the side plate and meshes with the helical gear on the helical gear 6. As shown in the figure, only the helical gear 6 is allowed to rotate in the direction shown (clockwise).

缆绳收放机构包括卷轴 14、卷绕在卷轴上的缆绳 9和固定在缆绳端部的活环扣 10。卷轴 14定位在两侧板 15间并与连接轴 13平行，缆绳 9采用钢缆（直径不小于 0.3厘米，长度 20米左右），缆绳 9内端固定在卷轴 14上，外端则连接一活环扣 10, 该活环扣 10可勾扣在固定环 11上。固定环 11可作为大楼安全救生设施之一被预先固定在高层建筑每一扇窗户附近的墙体上，而本实用新型的救生器也作为大楼安全救生设施之一被配备在每个房间内。 The cable retracting mechanism includes a reel 14, a cable 9 wound on the reel, and a loop 10 fixed to the end of the cable. The reel 14 is positioned between the two side plates 15 and parallel to the connecting shaft 13. The cable 9 is a steel cable (no less than 0.3 cm in diameter and about 20 meters in length). The inner end of the cable 9 is fixed on the reel 14 and the outer end is connected to a live The ring buckle 10 can be hooked on the fixing ring 11. The fixing ring 11 can be fixed in advance on the wall near each window of a high-rise building as one of the building's safety rescue facilities, and the lifesaving device of the present invention is also provided in each room as one of the building's safety rescue facilities.

如果让连接轴 13与卷轴 14联结，让连接轴 13直接驱动卷轴 14转动，也可以实现本实用新型.的目的，但会造成整个救生器过长等的问题。本实用新型利用齿轮组构成换向机构 , 同时实现传动与变速, 即让卷轴 14与连接轴 13平行定位在两侧板 15间。大齿轮 1固定在卷轴 14上，小齿轮 2固定在连接轴 13上，大齿轮 1与小齿轮 2啮合并定位在与摇把 8相对的另一侧支架侧板 15外。从而可将整个救生器的体积控制在较小的范围内，且重量分布均匀。 If the connecting shaft 13 is connected to the reel 14 and the connecting shaft 13 directly drives the reel 14 to rotate, the purpose of the present invention can also be achieved, but it will cause problems such as the entire lifesaving device being too long. The utility model uses a gear set to form a reversing mechanism, and simultaneously realizes transmission and speed change, that is, the reel 14 and the connecting shaft 13 are positioned in parallel between the two side plates 15. The large gear 1 is fixed on the reel 14, and the small gear 2 is fixed on the connecting shaft 13. The large gear 1 meshes with the small gear 2 and is positioned outside the side plate 15 of the bracket opposite to the handle 8. Therefore, the volume of the entire lifesaving device can be controlled in a small range, and the weight distribution is uniform.

在图 1所示的救生器实施例中，由于连接轴 13与卷轴 14之间的距离不应过大，因此，限制了连接轴 13与卷轴 14之间所形成的空间范围，进而由于该有限的空间范围使得卷绕在卷轴 14上的缆绳 9只能卷绕有限圈数，从而使得缆绳 9的长度由此受到限制；参见图 3, 在另一实施例中，为了克服上述问题，在两块侧板 15之间进一步引入另一块侧板 16, 由两块侧板 15、侧板 16、以及固定在侧板 15和侧板 16上的固定杆 12构成支架。其中，将靠近摇把 8—侧的侧板 15称为第一侧板 15, 将远离摇把 8—侧的侧板 15称为第二侧板 15。在该实施例中，连接轴 13定位在侧板 16和第一侧板 15之间，卷轴 14定位在侧板 16与第二侧板 15之间并与连接轴 13平行，齿轮组构成的换向机构仍然包括大齿轮 1和小齿轮 2，大齿轮 1固定在卷轴 14上，小齿轮 2固定在连接轴 13 上，大齿轮 1与小齿轮 2啮合并定位在侧板 16靠近摇把 8的一侧，该救生器中其余部件以及部件之间的连接关系与图 1所示的救生器相同，在此不再重复叙述。在该实施例中，由于连接轴 13 不再延伸到与远离摇把 8的侧板 15上，因此，不再会由于连接轴 13的存在而导致在连接轴 13和卷轴 14之间形成有限的空间范围，从而使得卷绕在卷轴 14上的缆绳 9的圈数不再受限，进而使得缆绳 9的长度可以更长，有利于高层使用者有效使用该救生器逃生。 In the embodiment of the lifesaving device shown in FIG. 1, since the distance between the connecting shaft 13 and the reel 14 should not be too large, the range of space formed between the connecting shaft 13 and the reel 14 is limited. The space range is such that the cable 9 wound on the reel 14 can only be wound a limited number of turns, so that the length of the cable 9 is limited accordingly. Referring to FIG. 3, in another embodiment, in order to overcome the above problem, A side plate 16 is further introduced between the side plates 15, and a bracket is formed by the two side plates 15, the side plates 16, and the fixing rod 12 fixed on the side plates 15 and 16. The side plate 15 near the 8-side of the handle is referred to as a first side plate 15, and the side plate 15 far from the 8-side of the handle is referred to as a second side plate 15. In this embodiment, the connecting shaft 13 is positioned between the side plate 16 and the first side plate 15, and the reel 14 is positioned between the side plate 16 and the second side Between the plates 15 and parallel to the connecting shaft 13, the reversing mechanism formed by the gear set still includes a large gear 1 and a small gear 2, the large gear 1 is fixed on the reel 14, the small gear 2 is fixed on the connecting shaft 13, and the large gear 1 It meshes with the pinion 2 and is positioned on the side of the side plate 16 close to the handle 8. The remaining components of the lifesaving device and the connection relationship between the components are the same as those of the lifesaving device shown in FIG. In this embodiment, since the connecting shaft 13 no longer extends to and away from the side plate 15 away from the handle 8, a limited space between the connecting shaft 13 and the reel 14 will no longer be formed due to the existence of the connecting shaft 13. Range, so that the number of turns of the cable 9 wound on the reel 14 is no longer limited, and thus the length of the cable 9 can be longer, which is beneficial for high-level users to use the lifesaving device to escape.

实施时也可只设置连接轴、摇把、刹车机构，不设置卷轴，将一滚桶固定在连接轴上，摇动摇把使连接轴转动,，带动滚桶转动，也能使卷绕在滚桶上的缆绳收放，实现发明目的。但此种实施方案，因对摇把的施力大、缆绳收放的可靠性较差，不提倡采用。 During the implementation, only the connecting shaft, the handle and the brake mechanism can be provided, and no reel is provided. A drum is fixed on the connecting shaft, and the connecting shaft is rotated by shaking the handle, and the drum is also rotated, and the winding on the roller can also be performed. The cable on the barrel is retracted to achieve the purpose of the invention. However, such an implementation scheme is not recommended because of the large force exerted on the handle and the poor reliability of cable retracting.

实施时，最好在救生器外再设置一个防护罩（或称机壳），不仅美观且可保证装置安全可靠地工作。 During the implementation, it is better to set up a protective cover (or casing) outside the lifeguard, which is not only beautiful, but also can ensure the safe and reliable operation of the device.

通常 20米长的钢缆已能满足逃生人员从六层楼的高层建筑上安全下降的需要，若高度超过 20米，则可采用接力的方法，先使用一个救生器将自己放降到某一个较低楼层，再利用该楼层房间中配备的救生器及墙体上的固定环将自己放降到更低的一个楼层，如此，尽管钢缆的长度是有限的，但最终可实现的下降高度却可以是任意的。 Usually a 20-meter-long steel cable has been able to meet the needs of escape personnel to descend safely from a six-story high-rise building. On the lower floor, the life-saving equipment provided in the room on the floor and the retaining ring on the wall are used to lower itself to a lower floor. Thus, although the length of the cable is limited, the descent height that can be achieved in the end It can be arbitrary.

为进一步保证逃生者的生命安全，本实用新型的装置还可辅以防火、防毒面罩及部分工具，如锤子等，供打碎窗户玻璃。 In order to further ensure the safety of the escapees, the device of the present invention can be supplemented with a fireproof, gas mask and some tools, such as a hammer, to break the window glass.

任何只要能摇动摇把 (约 10公斤力）的人员，都可使用本实用新型的装置，及时安全地从高层逃生，且操作筒单。 Anyone who can shake the handle (approximately 10 kg of force) can use the device of the utility model to escape from the high-rise in a timely and safe manner, and to operate the canister.
