The micromotion gate lock is formed as follows: a spring bolt locking device is arranged on the gate lock or a gate, when the gate is closed, the gate can horizontally rotate along with the gate lock, when an inclined plane of a spring bolt encounters a lock catch, the inclined plane generates strong collision with the lock catch through the inertance of the gate and manual kinetic energy, and the spring bolt is forced to move to retreat in the lock; the strong friction is generated between the inclined plane of the spring bolt and the outer edge of the lock catch in the process, and the friction needs to consume substantive energy; in order to realize that the gate closing and lock locking can be softly performed and required energy of the gate closing and the lock locking can be reduced, the scheme adopts a plurality of measures, and the measures are that the spring bolt locking device is arranged on the gate lock or the gate; when people open the lock, the spring bolt retreats into the lock, and the spring bolt locking device can automatically lock the spring bolt; and when the gate is closed, the spring bolt locking device encounters the outer edge of the lock catch, and the spring bolt locking device rapidly releases the spring bolt, so that the gate is locked, and the gate lock and the gate provided by the utility model can greatly reduce the required energy of the gate closing and the lock locking can be 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 type 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 leaned on the inertia of door and the kinetic energy and the snap close of manpower that strong collision takes 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 to live door lock 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 shell.This friction will consume lot of energy, and its this action that causes closing the door can't softly be carried out, and it directly causes producing because of 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 close if the dynamics of the latter end of door device stroke with energy when not enough, often cause 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 kinds of 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 the problem that therefore possibly occur is that bigger loud noise or the like is not gone up or produced to door lock.

Summary of the invention

Can softly carry out for the locking that reduces the locking energy needed of closing the door, let to close the door, this programme has been taked some measures.These measures are that the dead bolt locking device is being installed on the door lock or on the gate.Here said dead bolt locking device is meant and can when opening door lock, dead bolt be pinned, and when closing the gate, can easily let dead bolt eject the machine components of gate pinning or the combination of machine components 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 or the like 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 or the like.

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.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.
