Abstract

The utility model provides a safety cylinder lock. Because the lock tongue of a present spring lock is in the shape of a slope, the door can be opened by a rigid flake which is inserted in a door gap and presses the inclined plane of the lock tongue. The shortage provides the stealer with convenience. The utility model adopts the strip-shaped lock tongue without a slope. The possibility that the door is opened by the flake inserted in the door gap is stopped. The utility model is safer than the spring lock with the slope-type lock tongue in a certain degree.

Description

Safety cylinder lock

The utility model is the safe gate lock with shot about a kind of pick-proof.

The existing pin tumbler lock of being made up of tapered end, dead bolt, keeper, dead bolt box, handle, transmission bar, stop button etc. is nested and works with being fixed on keeper on the wall by being installed in a last telescopic ramped shaped dead bolt.Because telescopic dead bolt is a ramp type, so, not only can open it with key, in door, oppress the place, slope of dead bolt with the thin slice that matter is hard from crack between a door and its frame, also lock can be opened.At present, a kind of Lock with double safety guard is arranged, but open, lock equal inconvenience; Also have a kind of ramp type dead bolt that both had on lock body, have the door lock (as the door lock on some automobiles) of vertical bar type keeper again, also only vertical bar section bar material is used as keeper, dead bolt is still ramp type.

No matter the purpose of this utility model is to provide a kind of and which kind of thin slice oppresses dead bolt from crack between a door and its frame with, all can not make the safe gate lock with shot of lock breakdown.

The utility model is finished as follows.The telescopic ramp type dead bolt of existing pin tumbler lock rehandling is become not have the vertical bar type of gradient, open an openning that can make the dead bolt turnover more, load onto the pellet shot from a slingshot bolt within it and get final product (scheme one) at existing keeper outer wall; Perhaps, with the outer wall rehandling sloping type of existing keeper also can (scheme two).

Below in conjunction with accompanying drawing and implement two examples the utility model is described in further detail.

Fig. 1 is existing pin tumbler lock schematic diagram.

Fig. 2 is a vertical bar type dead bolt schematic diagram of not having a gradient of the present utility model.

Fig. 3 is the keeper schematic diagram that the utility model is equipped with the pellet shot from a slingshot bolt.

Fig. 4 is the keeper sectional drawing that the utility model is equipped with pellet shot from a slingshot bolt and pellet shot from a slingshot.

Fig. 5 is that the utility model is contained in the pellet shot from a slingshot bolt schematic diagram in the keeper.

Fig. 6 is the keeper schematic diagram that the utility model has the slope.

Embodiment one: the dead bolt 1 among Fig. 2 with door close and translation, during keeper 2 to Fig. 3, earlier through dead bolt inlet 6, rush open again tightly be posted on dead bolt enter the mouth on 6 inwalls pellet shot from a slingshot bolt 8(as shown in Figure 5, form by hard laminate 9, rotating shaft 10 and spring 11), the keeper 2 of being allowed for access then.When treating that dead bolt 1 enters keeper 2 fully, pellet shot from a slingshot bolt 8 is closed voluntarily, has stopped up dead bolt inlet 6, and pellet shot from a slingshot 8A plays a part fixedly dead bolt 1, makes dead bolt 1 be unlikely to skid off naturally greatly because of activity space.So just, with on the door lock.If, when needing insurance, can twist the stop button 5A on Fig. 3 keeper 2,, can insure just the lock in the stop button 5A is nested with safety groove 1A on Fig. 2 dead bolt 1 as in door, locking a door.During unlatching (if last insurance, first opening safety), as the way of existing unlatching pin tumbler lock, with key turns tapered end 3, drive dead bolt 1 by transmission bar 4, or rotate handle 5, drive the direction translation of dead bolts 1 by handle 5 to door, dead bolt 1 just can be by lock-tongue port 7 release lock button box 2; Perhaps, tapered end 3, transmission bar 4 are connected with the pellet shot from a slingshot bolts 8 in the keeper 2, with key turns tapered end 3, drive pellet shot from a slingshot bolts 8 by rotation strip 4, pellet shot from a slingshot bolt 8 is opened, dead bolt 1 again can be by the dead bolt 6 release lock button boxes 2 that enter the mouth under the resiliency urged of pellet shot from a slingshot 8A.Like this, just, lock can be opened.

Embodiment two: as shown in Figure 6, when the slope 12 of telescopic vertical bar type dead bolt 1 and keeper 2 is inconsistent, vertical bar type dead bolt 1 just can temporarily be withdrawn, and is being in and can be subjected to the manpower effect and auto-closing when closing in the scope automatically when it moves to door.In the ordinary course of things, door does not reach holding position, realization for closing door automatically.

Use the utility model will reach desired function, when installing, it should note: the angle that Men Kaizhi often need be kept it, the bonding surface that makes housing (1) and upper door frame is the translation of the upper door frame back side (H requires not super scope), the axis of axostylus axostyle (2) is parallel with the door pivot axis, pin (7) should add upper push-rod and fork length difference sum greater than H to the distance of door pivot (10), making the β angle is 0 °, make α less than limiting angle simultaneously, pin (7) (wooden door should be wooden gong nail) is installed then, housing (1) is fixed in upper door frame, and then door can be realized that maintenance door on its required angle is opened and close a function automatically less than this open angle.

Claims

1, a kind of safe gate lock with shot of being made up of dead bolt 1, keeper 2, tapered end 3, transmission bar 4, handle 5, stop button 5A and dead bolt box is characterized in that dead bolt 1 is not have a vertical bar type of gradient.

2, by the described safe gate lock with shot of claim 1, it is characterized in that being equipped with in the keeper 2 the pellet shot from a slingshot bolt 8 that can open, close.

3,, it is characterized in that keeper 2 outer walls have dead bolt inlet 6 according to the described safe gate lock with shot of claim 2.

4, by claim 2,3 described safe gate lock with shot, the method for the existing pin tumbler lock of available unlatching is opened, and it is characterized in that also available transmission bar 4 drives the method unlatching that pellet shot from a slingshot bolt 8 is opened.
