Novel manual safety riser

Abstract

The invention discloses a novel manual safety lifter. The manual safety lifter comprises a bracket and a rotary handle which is arranged on the bracket and can rotate a lifting rope; the lower part of the bracket is provided with a buckle for hoisting human or objects; the upper part of the bracket is also provided with a locking control device for controlling the rotary handle to rotate in single direction; the locking control device comprises a seat frame and a rotary gear connected with the rotary handle; the seat frame is also provided with a lock tooth shaft which is provided with inverse lock teeth like Chinese character 'ba' and is engaged with the rotary gear; and the upper part of the bracket is also provided with a lifting rope antiskid for locking the lifting rope to prevent the bracket with the human or objects from falling as the rotary handle is out of control. In the novel manual safety lifter, the locking control device which controls the rotary handle for furling the lifting rope to rotate in single direction is arranged on the bracket; the top of the bracket is provided with the lifting rope antiskid; and the novel manual safety lifter has a simple structure, skillful concept, convenience and practicability, does not have phenomena that an object falls off by accident and the like when the rotary handle raises or declines the object through manual control and is suitable for a common family to use.

Description

technical field [0001] The invention relates to the technical field of lifting equipment manufacturing, in particular to a new type of safety lifting device for manually lifting people or objects. Background technique [0002] At present, there are many types of lifting equipment sold on the market. Most of them have complex structures, good lifting effects, and are safe and fast. Ordinary people mostly use ropes to lift or lower objects when lifting or lowering objects. Although ropes are widely used, unsafe factors such as accidental falling of objects are prone to occur due to manual pulling of ropes, and sufficient strength is required when lifting objects. Physical strength can be used, and the operation is also very troublesome. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a manual safety lifter with simple structure, ingenious conception, convenience and practic...
