Description

Technical Field

[0001] This utility model belongs to the field of security equipment, specifically relating to a high-rise building escape descent device. Background Technology

[0002] High-rise escape descent devices are mainly used for emergency evacuation and escape in high-rise buildings during natural or man-made disasters. The earliest high-rise emergency escape descent devices consisted of a shell, a transmission mechanism inside the shell, and a rope connected to the transmission mechanism. The transmission mechanism typically consisted of a set of gears, which had drawbacks such as complex structure, susceptibility to failure, and high cost. To address these issues, the applicant applied for a Chinese utility model patent with authorization publication number "CN 220477960 U" entitled "A High-Rise Escape Descent Device." This patent simplifies the structure by replacing the traditional gears with a circular damping disc inside the shell. However, it still has the following drawbacks: 1. The braking mechanism is relatively complex and lacks stability; 2. When users operate the braking mechanism in a state of panic, they are prone to improper force, leading to over-unlocking and causing the escapee to descend too quickly, resulting in danger. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a high-rise escape descent device with a simpler structure and higher safety.

[0004] To solve the above problems, the technical solution adopted by this utility model includes: a shell, a winding reel disposed inside the shell, a rope wound on the winding reel, and a braking mechanism disposed on the shell. One end of the rope extends from the upper end of the shell and the other end extends from the side of the shell. The braking mechanism includes a braking operating rod, a fixed damping rod, a movable damping rod, and a braking spring. The front end of the braking operating rod is rotatably mounted on the upper part of the shell via a pivot. Two movable damping rods are disposed at the front end of the braking operating rod via a bracket. The winding reel is provided with a groove for the bracket to extend into. Two fixed damping rods are disposed on both sides of the bracket and connected to the shell. The rope passes between the two movable damping rods and is located between the fixed damping rod and the winding reel. The braking spring is disposed at the front end of the braking operating rod and is used to press the bracket into the groove.

[0005] The upper end of the housing is provided with a brake spring seat, and the brake spring is installed in the brake spring seat.

[0006] The lower end of the outer casing is provided with a hanging hole.

[0007] The upper end of the outer shell is provided with a positioning post for positioning the rope.

[0008] The advantages of this high-rise escape descent device are as follows: 1. Since the braking mechanism is in a locked state by default, when the escapee gently moves the brake lever downward, it is unlocked, allowing the escapee to descend slowly; when the escapee exerts excessive force, it will lock again, thus greatly improving safety; 2. The braking mechanism has the advantages of simple structure, convenient operation, labor saving, and good stability.

[0009] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0010] Figure 1 This is a structural schematic diagram of the high-rise building escape descent device of this utility model; Figure 2 This is a cross-sectional view of the high-rise building escape descent device of this utility model; Figure 3 This is a schematic diagram of the braking mechanism of this utility model. Detailed Implementation

[0011] Reference Figure 1-3 As shown, the high-rise escape descent device of this utility model includes a housing 1, a winding reel 2 disposed inside the housing 1, a rope 3 wound on the winding reel 2, and a braking mechanism 4 disposed on the housing 1. One end of the rope 3 extends from the upper end of the housing 1, and the other end extends from the side of the housing 1. The braking mechanism 4 includes a braking operating rod 5, a fixed damping rod 6, a movable damping rod 7, and a braking spring 8. The front end of the braking operating rod 5 is rotatably mounted above the housing 1 via a pivot 9, and the two movable damping rods 7 are disposed at the front end of the braking operating rod 5 via a bracket 10. The winding reel 2 is provided with a groove 11 for the bracket 10 to extend into, and the two fixed damping rods 6 are disposed on both sides of the bracket 10 and are connected to the housing 1. The rope 3 passes between the two movable damping rods 7 and is located between the fixed damping rod 6 and the winding reel 2. The braking spring 8 is disposed at the front end of the braking operating rod 5 and is used to press the bracket 10 into the groove 11. When the braking mechanism 4 is in its default state, under the action of the braking spring 8, the bracket 10 is pressed into the groove 11, causing friction between the rope 3 and the movable damping rod 7 and the winding reel 2, thereby achieving locking. When the braking operating lever 5 is gently pushed downwards, the friction between the rope 3 and the movable damping rod 7 and the winding reel 2 is reduced, allowing the escapee to descend slowly. When the escapee exerts excessive force, friction is generated between the rope 3 and the movable damping rod 7 and the fixed damping rod 6, thereby locking again.

[0012] Preferably, the upper end of the outer casing 1 is provided with a brake spring seat 12, and the brake spring 8 is installed in the brake spring seat 12 to facilitate the fixing of the brake spring 8.

[0013] Preferably, the lower end of the outer casing 1 is provided with a hanging hole 13 to facilitate connection with a hook or other equipment.

[0014] Preferably, the upper end of the outer shell 1 is provided with a positioning post 14 for positioning the rope 3.
