Abstract

The invention discloses a lateral pressure type self-locking device which comprises a shell, wherein the shell is provided with a fixed shell wall and a movable shell wall; the fixed shell wall and the movable shell wall are enclosed to form a cavity at the middle part of the shell; the movable shell wall is provided with a guide groove; guide holes are formed respectively arranged at the upper end and the lower end of the guide groove; the guide groove is communicated with the cavity; and a bracket is also arranged on the inner wall of the shell and is provided with a rolling wheel shaft. The lateral pressure type self-locking device has the advantages that a connector can successfully pass through the lateral pressure type self-locking device without additional auxiliary operation, so that the safety hidden dangers are lowered; and in addition, the lateral pressure type self-locking device is contacted with a steel strand in a rolling way, so that the motion ability of the lateral pressure type self-locking device is improved, and the abrasion of the steel strand is also reduced.

Description

technical field [0001] The invention relates to a steel strand wire fall prevention device, in particular to a 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. When this type of self-locking device passes through the connector, it usually requires manual additional actions to pull the steel strand out of the connector, and then pull the steel strand back into the connector after the self-locking device passes through smoothly. Because this type of self-locking device requires additional auxiliary operations when passing through the connector, which increases the workload of the operator and also brings potential safety hazards. Contents of the invention [0003] Based on this, the present invention overcomes the defects of the prior art and provides a la...
