Problems solved by technology

The existence of the power cord has brought great troubles and even hidden dangers to the test
In addition, the power cord is exposed to the outdoors for a long time, which is prone to aging, and it is easy to freeze in winter, which is also very unfavorable to the power cord itself.

Abstract

The invention discloses a wireless control automatic releaser, comprising a case, a charging battery, a wireless control system, an electromagnetic mechanism and a releasing mechanism. The wireless control automatic releaser is characterized in that the case is in a cylinder-shaped structure and is provided with an upper cavity and a lower cavity which are coaxial; the wireless control system comprises a remote controller, a control switch, an antenna and a wireless control module; the electromagnetic mechanism comprises an electromagnet and an iron core; and the releasing mechanism comprises a releasing sleeve, a movable sleeve and a releasing pin which are sequentially sheathed. The wireless control automatic releaser has the following characteristics: 1) the wireless control system can control a test process within the range of 500m by virtue of the remote controller, inconvenience of a power line to the test is eliminated, and safe distance coefficient of testers and the test is improved; 2) a conical bore of the movable sleeve is designed, thus the aim of releasing the releasing pin is achieved; and 3) a rubber band is designed at the periphery of a through hole of the releasing sleeve, thus the aim of locking the releasing pin is achieved.

Description

technical field [0001] The invention relates to an automatic release device, which is used for impact tests of safety belts, impact tests of anti-falling devices, impact tests of speed difference devices, impact tests of safety nets, or the occasions of releasing heavy objects. Background technique [0002] Safety belts, speed differentials, buffer bags and other appliances are a kind of safety protection equipment specially designed for workers working at heights to prevent falls from heights. Personnel working at heights are likely to fall suddenly when working at heights, resulting in serious consequences. At this time, safety protection equipment at heights plays a great role. However, despite this, it is not uncommon for accidents of falling casualties to occur when safety protection equipment is used. Therefore, the use of qualified safety protection equipment is the key to preventing falls of workers working at heights. A sudden fall of a person working at a height ...
