Abstract

The invention discloses clamp type self-lock equipment which comprises a housing, a connecting rod transmission structure and a component force transmission structure, wherein the housing is provided with a fixed housing wall and a movable housing wall; the connecting rod transmission structure comprises a rocker arm, a steering connecting rod, a horizontal connecting rod and a horizontal sleeve, wherein one end of the rocker arm is connected to the outer wall of the fixed housing wall opposite to the movable housing wall; one end of the steering connecting rod is connected to the rocker arm, and the other end is movably connected with the first end of the horizontal connecting rod; the horizontal connecting rod is sleeved with the horizontal sleeve; the horizontal sleeve is fixed on the outer wall of the fixed housing wall opposite to the movable housing wall; the component force transmission structure comprises a scissor connecting rod, a movable clamp and a braking component, wherein one end of the scissor connecting rod is movably connected with the movable clamp, and the other end is movably connected with a second end of the horizontal connecting rod through a rotating shaft; and the braking component is fixedly connected to the end part of the movable clamp. Therefore, the clamp type self-lock equipment has a more reliable self-lock effect.

Description

technical field [0001] The invention relates to a fall prevention device, in particular to a clamp type self-locking device. Background technique [0002] Existing anti-falling devices for steel strands usually include components such as laces, safety ropes, connectors, and self-locking devices, wherein the self-locking device is the core component of this type of device. At present, most of the self-locking devices at home and abroad simply use the rocker arm to drive the brake block to realize self-locking, and the effect of self-locking is not reliable enough. Contents of the invention [0003] Based on this, the present invention overcomes the defects of the prior art and provides a pincer-type self-locking device whose self-locking effect is more reliable. [0004] Its technical scheme is as follows: [0005] A pincer type self-locking device, which includes a housing, a connecting rod transmission structure and a force component transmission structure, the housing ...
