Multi-connecting-rod structure with self-locking function

Abstract

The invention discloses a multi-connecting-rod structure with a self-locking function. The multi-connecting-rod structure comprises an electric push-pull rod, an elastic adapter, a plurality of self-locking connecting rods, a movable pedal fixing bracket and a movable pedal. Through stretching of electric push-pull rod, the movable pedal is supported flat to provide a platform for operators, afteroperation is completed, the movable pedal is folded through retracting of the electric push-pull rod, when the movable pedal is supported flat, self-locking is achieved through the multiple self-locking connecting rods, and the connecting rods are fixed into a whole, so that it is ensured that the whole structure is safe and reliable; and the movable pedal and the electric push-pull rod are located in an elastically connected state, so that the load carried by the movable pedal is transferred to the multiple self-locking connecting rods, and the requirement for the structural strength of theelectric push-pull rod is reduced. According to the multi-connecting-rod structure, the movable pedal is reliably supported and folded in a small mounting space, and the potential leakage problems ofpneumatic and hydraulic driving equipment, the safety and mounting size limitation problems caused by high-voltage driving equipment and the bearing capacity problem of low-voltage driving equipment are eliminated.

Description

technical field [0001] The invention belongs to the field of safety equipment, and in particular relates to a multi-link structure with a self-locking function for supporting pedals. Background technique [0002] In a social environment where the people-oriented concept is deeply rooted in the hearts of the people, "safety first" is a basic consideration that is recognized by all walks of life. Effectively ensuring the safety of employees is an important responsibility of team managers and equipment designers. The present invention takes the vacuum chamber as the application background, and proposes a pedal support structure suitable for use in an environment where space is limited and oil and gas leakage are not allowed, providing users with a safe and reliable work platform and folding and folding after work . [0003] The vacuum chamber is in the configuration of an upper cavity 101 and a lower box 102, and equipment such as a multi-degree-of-freedom motion mechanism 103...

Problems solved by technology

Through market research, it is found that it is difficult to find an electric push-pull rod in the existing products that meets the needs of the site in terms of carrying capacity and installation size. When the required electric push-pull rod is used as the driving device, the actual effect of motion synchronization between multiple electric push-pull rods is not satisfactory due to the influence of factors such as installation position deviation and motion synchronization equipment performance, which will cause equipment damage
