Description

Clutch capable of preventing violent opening and muting

Technical Field

The utility model relates to a door lock clutch technical field specifically is a prevent that violence from opening and the clutch of silence.

Background

Along with the continuous improvement of the living standard of people, the convenient and fast fingerprint coded lock continuously enters thousands of households, and more users are provided with the fingerprint locks and more factories are provided with the fingerprint locks. Fingerprint locks now have two technical routes: one is a mechanical lock body with a motor clutch, and the other is a fingerprint lock panel integrated with a motor clutch; the existing market is also dominated by panel integrated belt motor separation and reunion fingerprint lock fault rate is low, the cost performance is high and easy maintenance etc. wherein have a lot of key spare parts for example: the door opening mode includes several door opening modes, including one-hold opening mode, automatic sliding mode, etc. The clutch is one of the key parts of the fingerprint lock, so that various manufacturers design different types of clutches, such as a clutch which is opened immediately after being held, an automatic sliding cover type clutch and the like according to different door opening modes, and a stainless steel finish casting process is required, so that the production process is complex and the production flow is long. Therefore, a multifunctional clutch with excellent performance and low cost, which is universal with a one-grip-opening and automatic sliding cover, is in need of research.

At present, a main clutch is arranged on an upper clutch at a handle position and is reversed, and a lower clutch is also reversed, so that the door lock can be normally used. The fingerprint lock is opened by holding one of mainstream in the market, and both the fingerprint head is on hand, and its fingerprint line must pass through the separation and reunion, has the direct line connection intelligence main control board of separation and reunion down now all, and the switching-over process leads to the fingerprint line very fragile, and switching-over back switch door fingerprint line is continuous to take place the friction with separation and reunion and other subassemblies, influences life. The lower clutch is returned to positive and mainly by the separation and reunion completion behind the lock, leads to the lock to use for a long time later, because the separation and reunion is not returned positive lock and can not be opened. There is no clutch which is integrated, has low cost and is made of iron and can prevent the sleeve from rotating the handle and being opened violently.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a prevent that violence is opened and clutch of silence to the last separation and reunion commutation back at the handle position is installed to the clutch of the present mainstream that proposes in solving above-mentioned background art, and lower separation and reunion also need the switching-over, the ability normal use lock. The fingerprint lock is opened by holding one of mainstream in the market, and both the fingerprint head is on hand, and its fingerprint line must pass through the separation and reunion, has the direct line connection intelligence main control board of separation and reunion down now all, and the switching-over process leads to the fingerprint line very fragile, and switching-over back switch door fingerprint line is continuous to take place the friction with separation and reunion and other subassemblies, influences life. The lower clutch is returned to positive and mainly by the separation and reunion completion behind the lock, leads to the lock to use for a long time later, because the separation and reunion is not returned positive lock and can not be opened. There is no clutch which is integrated, has low cost and is made of iron and can prevent the sleeve from rotating the handle and being opened violently.

In order to achieve the above object, the utility model provides a following technical scheme: a clutch for preventing violent opening and muting comprises a clutch body;

the clutch body includes the shrouding, the shrouding bottom is connected with the separation and reunion casing, the top activity of shrouding inserts down the separation and reunion casing, and the separation and reunion extends through the separation and reunion casing down, the bottom activity of separation and reunion casing has inserted silence circle b, and the top cover of silence circle b has connect the jump ring, the top activity that has cup jointed still voice coil c and silence circle c on the bottom inner wall of separation and reunion casing has prevented violence and has opened the circle, and the outside activity that prevents violence and open the circle has cup jointed the torsional spring, the left side extension one side of torsional spring is provided with the switching-over screw, the top of preventing violence and opening the circle evenly is connected with the breaking point, the top of preventing violence and opening the circle is provided with the commutator bar, and the breaking point activity on anti-violence opening circle top inserts the commutator bar, commutator bar left side swing joint has the motor, the top swing joint of lower separation and reunion has the square pole spacing, it is spacing to go up separation and reunion left side bottom activity connection of thimble spacing, and the left side activity of thimble spacing has inserted the thimble body, the top of square pole spacing, the movable side of the fingerprint lock body that the movable handle is connected with the top of the movable lock body, the fingerprint lock body that the top of the movable line that the lock body that the top of voice coil a, and the fingerprint lock body that the activity is connected with the movable lock body, the movable lock body that the fingerprint lock body, the bottom surface of the movable lock body that the fingerprint lock body that the top of voice coil that the activity is inserted, and the activity is inserted on the left side of the activity is connected with, the activity is connected with the left side of the movable lock body, and the movable side of the activity of voice coil bottom surface of the fingerprint lock body, the activity is inserted.

Preferably, only the lower clutch reversing which is installed on the handle is needed, the upper clutch reversing is not needed, the fingerprint line is always centered, the square rod and the thimble body can not be in a reasonable position always due to the fact that the fingerprint line is clamped and ground in a reversing mode and the return function of the square rod and the thimble body is achieved, the upper clutch and the reversing sheet are made of a stamping process, and the handle is reliable in performance and low in cost.

Preferably, all have wear-resisting engineering plastic gaskets between each accessory to play the silence effect, excellent performance and low cost are applicable to and hold open and automatic sliding closure general type of joining in marriage promptly, convenient to use, and application scope is wide, has fine popularization prospect in this technical field.

Preferably, only need install the lower separation and reunion switching-over on the handle, need not to go up the separation and reunion switching-over, and the separation and reunion keeps the state of placing in the middle always under the door lock does not have the action condition, guarantees that the fingerprint line is placed in the middle always, can not block, grind fingerprint line because of rotating the handle switching-over, goes up the separation and reunion and takes square pole and thimble body return function, makes square pole and thimble body be in reasonable position always, when external force violently rotates the handle, prevents that the violence opens the circle disconnection, makes the handle rotate any angle and can not drive the separation and reunion and open the door lock.

Compared with the prior art, the beneficial effects of the utility model are that:

1. through being provided with the commutator segment, the ring is opened to the anti-riot power, apply the rotatory handle of enough external force to the handle and open the door, go up the separation and reunion and the commutator segment is opened the ring by the anti-riot power and is linked, and two contact feet of circle are opened to the anti-riot power can be because external force and fall absolutely, and lower separation and reunion and commutator segment link absolutely, make down the separation and reunion be in idle running state, can not open the lock.
