Turning anchor hook capable of measuring distance

Abstract

The invention discloses a turning anchor hook capable of measuring the distance. The turning anchor hook comprises a climbing rope and a crossbow arrow tail rod type anchor hook body; the climbing rope is connected with the crossbow arrow tail rod type anchor hook body, the crossbow arrow tail rod type anchor hook body is provided with a conventional crossbow arrow tail and a rod part, and can be installed on a conventional crossbow arrow shooting device for shooting, and a distance measurement device is arranged on the crossbow arrow tail rod type anchor hook body; the crossbow arrow tail rod type anchor hook body is provided with a wind deflector which is provided with a wind receiving surface, and an elastic clamping hook is arranged at the end, far away from a rotating shaft, of the wind deflector; and the climbing rope is provided with a rope knot and a rope fastener knot or rope sleeve or grabbing hand. By means of the turning anchor hook, difficulties generated during motions such as hunting, climbing holdback crossing of people on field are overcome, the structure is simple, carrying is convenient, the functions are powerful, and the performance is reliable; and the distance between the long handle crossbow arrow and a target is measured through a wireless method, a target object can be hit or entangled accurately, climbing obstacle crossing is facilitated, and a great advance of an outdoor moving device is achieved.

Description

technical field [0001] The invention relates to the field of anchor hooks, in particular to a steering anchor hook capable of measuring distances. Background technique [0002] Rangefinders can be divided into the following three categories from the basic principle of distance measurement: Laser rangefinders are instruments that use lasers to accurately measure the distance of a target. When the laser range finder is working, it emits a very thin laser beam to the target, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculates the distance from the observer to the target. Laser range finder is currently the most widely used range finder, and laser range finder can be classified into handheld laser range finder (measurement distance 0-300 meters), telescope laser range finder (measurement distance 500-3000 meters) . The ultrasonic range finder measures accor...

Problems solved by technology

According to the published information at home and abroad, more anti-fall devices are used for climbing steel ladders, which require thin steel wire ropes to pass through the top pulley of the ladder or be fixed on the steel ladder. For the first installation of this device A climber cannot provide effective protection, and it is not convenient to climb with this device

Therefore, lack a kind of device that can replace operator's climbing straight ladder, and when developing this climbing device, need a kind of climbing hook that fixes this device, its supporting force of traditional hook head is insufficient, is not easy to move Middle buckle support, easy to unhook
