Abstract

The invention discloses a micro-lock for a door, and belongs to the technical field of antitheft appliances. When closed, a door drives a lock for the door to horizontally rotate, and when in contact with a lock catch, an oblique plane of a spring bolt is severely collided with the lock catch by the aid of the inertia of the door and kinetic energy of a person, so that the lock catch moves back into the lock; a portion between the oblique plane of the spring bolt and the outer edge of the lock catch severely rubs with a portion between the spring bolt and a lock case in the procedure, and a large quantity of energy is consumed during rubbing. In order to reduce energy required for closing and locking the door and enable the door to be closed and locked gently, the scheme includes measures that a spring bolt locking device is mounted on the door or the micro-lock for the door; when the micro-lock is unlocked, a spring bolt retreats into the micro-lock, and the spring bolt locking device locks the spring bolt automatically; when the door is closed and the spring bolt locking device is in contact with the outer edge of a lock catch, the spring bolt locking device quickly releases the spring bolt, and the door is locked. The micro-lock in the scheme has the advantage that energy required for closing and locking the door can be greatly reduced.

Description

The fine motion door lock

Technical field

A kind of fine motion lock is a technical field of antitheft apparatus.

Background technology

In our daily life, be unable to do without lock, particularly door lock.The gate generally all is equipped with single tongue lock or many tongues lock (hereinafter to be referred as door lock), and their operating principle is the same.This class door lock is very convenient when locking a door, as long as the gate of firmly wrenching or thrust, dead bolt will with the snap close outer rim produce insert after clashing in the bonnet lock hole gate lock on.The structure of door lock is very simple, and an inclined-plane is arranged on the dead bolt, and door is being with door lock to horizontally rotate at closing time, and when snap close was run on the inclined-plane of dead bolt, the inclined-plane of dead bolt by the inertia of door and kinetic energy and the snap close of manpower strong collision took place, and forces the dead bolt displacement to be return in the lock.When the outer rim of crossing snap close when dead bolt arrived the hole of snap close, dead bolt inserted in the square hole of snap close door lock is lived under the effect of spring force.In this process, produced strong friction between the inclined-plane of dead bolt and the snap close outer rim and between dead bolt and the lock housing.This friction will consume lot of energy, and its this action that causes closing the door can't gently be carried out, and it directly causes producing because overexerting at closing time irksome strong sound at every turn simultaneously.This is a big shortcoming of existing door lock.Be equipped with in the automatic door of door closer at some, this big shortcoming is being closed when if the dynamics of the latter end of door device stroke and energy are not enough, often cause door can not automatic locking on.In order to provide enough energy to door lock, door closer has to strengthen energy-stored spring, so makes the unlatching at gate become heavy again, because door closer will be stored the locking energy needed of closing the door in this course.A lot of local gates are blocked in outdoors because of unable the opening of the too heavy Xiao Tong of order.The increasing of energy-stored spring simultaneously produces loud noise when the surplus of energy causes the gate to be closed again.Because door closer mostly utilizes oil damping work, these several factors are difficult to find an equalization point, even spending all the tremendous effort mixes up the gate, original equalization point will be broken in case temperature, humidity etc. change, and therefore the problem that may occur is that bigger loud noise etc. is not gone up or produced to door lock.

Summary of the invention

Can gently carry out for the locking that reduces the locking energy needed of closing the door, allow to close the door, this programme has been taked some measures.These measures are that the dead bolt locking device is installed on door lock or at the gate.Here said dead bolt locking device refers to and can when opening door lock dead bolt be pinned, and can easily allow dead bolt eject the machine components of gate pinning or the combination of machine components when closing the gate again.The dead bolt locking device that can reach this purpose is very many, mainly include the interior reed-type dead bolt locking device that is contained on the door lock, outer reed-type dead bolt locking device, outer bell-type dead bolt locking device etc. in these devices, the door that is contained on the door is gone up outer bell-type dead bolt locking device, door upper reed plate formula dead bolt locking device etc.

The dead bolt locking device is a kind of very simple inching gear in fact, and it is unblanked people, and dead bolt has pinned dead bolt when being retracted in the lock automatically, so when closing the gate, dead bolt again need not produce strong collision and friction with snap close.Closing the gate, when the dead bolt locking device was run into snap close, dead bolt was just in time aimed at the lockhole of snap close, and the dead bolt locking device discharges dead bolt rapidly, and on gate lock, this collision is that very slight machinery triggers.The energy needed when door lock of use this programme and gate can reduce to close the door locking significantly can become softly the action of the locking of closing the door, and has eliminated the irksome sound of closing the door.
