Problems solved by technology

However, the structure of this descender is not reasonable enough. If the user keeps holding the switch tightly due to factors such as tension, it is easy to cause the descending speed to be too fast, and may even cause panic and miss, and the rapid descending speed is also prone to landing impact

Embodiment Construction

[0018] Such as figure 1 , figure 2 As shown, an anti-panic downhill device includes a body 1, a first cam 2 and a second cam 3, the body 1 is provided with a side wall that limits the running path of a rope 8, and the first cam 2 is rotatably connected to On the body 1, the second cam 3 is fixedly connected to the body 1, a first gap 4 is provided between the first cam 2 and the second cam 3, and one end of the rope 8 passes through the first gap 4 and then along the second The second cam 3 passes through the main body 1 and is set downward. The other end of the rope 8 passes through the first gap 4 and then goes out of the main body 1 along the first cam 2 and is set upward. The main body 1 is also rotatably connected with a lock block 5 , the lock block 5 is arranged below the second cam 3, the lock block 5 is provided with a protruding tooth 51 in contact with the rope 8, and the body 1 is also provided with a through hole 11 for connecting with a safety buckle.

Abstract

The invention relates to a panic-proof downhill gear, comprising a main body, a first cam and a second cam, the first cam is rotatably connected to the main body, a first gap is arranged between the first cam and the second cam, and the main body is also A lock block is rotatably connected, the lock block is arranged below the first cam, and the lock block is provided with protruding teeth contacting with the rope; the advantages of the present invention: the rope is placed horizontally through the first rope, the first cam and the second cam It is wound on the body in an S-shaped way, and the rope is stuck by the contact between the convex teeth on the lock block and the rope. Due to the contact process between the convex teeth and the rope, the convex teeth increase the friction with the rope and improve the locking. Second, because the lock block and the body are connected in rotation, the rope drives the lock block to slide left and right on the body during the descending process of the rope up and down, which effectively slows down the rope's descending speed and does not require an additional switch to trigger the lock. The opening of the block simplifies the overall structure and improves the safety performance.

Description

technical field [0001] The invention relates to an anti-panic downhill device. Background technique [0002] In the fields of high-rise fire fighting or high-altitude operations, it may occur that personnel must descend by ropes. Descending personnel can use the method of directly grasping the rope to climb, although it is convenient, it requires high physical strength and skills, and it is not safe. Now there is also a special rope descender, the rope can be threaded around it, and the descender can only be lowered by holding the descender with the hand to turn on the switch, which improves safety, reduces the skill requirements of the user, and saves physical strength. However, the structure of this descender is not reasonable enough. If the user has been holding the switch tightly due to factors such as tension, it is easy to cause the descending speed to be too fast, and may even cause panic and miss, and the fast descending speed is also prone to landing impact.
