Multi-lock-rod lock

Abstract

The invention discloses a multi-lock-rod lock. The multi-lock-rod lock comprises a side box and a side box body; a fixing box is arranged on one side of the side box; an inner cavity is formed in theside box body; internal sliding cavities which are symmetrical up and down are formed in the side box body in a communicating mode; sliding-out blocks are arranged in the internal sliding cavities ina sliding mode; power connecting springs are elastically arranged between the sliding-out blocks and the end walls of the inner sliding cavities; a clamping device used for enabling the side box and the side box body to be indirectly clamped after rotating to achieve multiple locking is arranged in the side box and the fixing box; clamping slopes are arranged in the sliding-out blocks. and the clamping slopes are arranged to abut against the fixing box. According to the multi-lock-rod lock, when the side box gets close to the wall bodies on the two sides and one side of the opposite side wallbody, the side box body can be used for being fixed to the wall bodies and the opposite side wall body so that the side box can be stably fixed when being opened and closed; and moreover, the side boxand the side box body are indirectly fixed by adopting multiple lock columns, so that the firmness of the lock is improved.

Description

technical field [0001] The invention relates to the technical field of lock equipment, in particular to a multi-lock bar lock. Background technique [0002] Most of the common locks only have a single telescopic locking cylinder. The problem caused by this is that when a single lock cylinder is used, it is easy for people to break the equipment and the lock will be damaged immediately, and the problem caused is the safety of the lock. Reliability is reduced, and the existing locks cannot be locked at the two limit positions behind the door switch, resulting in that if the door is opened and the wind blows, the door will be closed suddenly, and if the key is left in the room Inside, it will make people unable to open the door in time and cause people to be stranded outside the house. Due to the existence of the above-mentioned shortcomings, the existing locks cannot meet the normal use of personnel and the corresponding anti-theft and anti-tampering requirements, and the lock...

Problems solved by technology

[0002] Most of the common locks only have a single telescopic locking cylinder. The problem caused by this is that when a single lock cylinder is used, it is easy for people to break the equipment and the lock will be damaged immediately, and the problem caused is the safety of the lock. Reliability is reduced, and the existing locks cannot be locked at the two limit positions behind the door switch, resulting in that if the door is opened and the wind blows, the door will be closed suddenly, and if the key is left in the room Inside, it will make people unable to open the door in time and cause people to be stranded outside the house. Due to the existence of the above-mentioned shortcomings, the existing locks cannot meet the normal use of personnel and the corresponding anti-theft and anti-tampering requirements, and the locks are suitable for doors. The locking effect with the door frame is low, and the efficient locking function of the equipment cannot be realized, and due to the existence of the above shortcomings, people may be stranded outside the house, and even in the event of a fire, the door cannot be kept open when the door needs to be opened so that people can escape quickly. Open, so that the safety of personnel is threatened
