Abstract
The utility model discloses an automatic bolt-limited double-head door lock, which belongs to the technical field of locks. The utility model is mainly characterized in that a driving mechanism of a set bar is composed of a shifting block and a shafting plate, a set bar body is provided with a bolt limiting hook, and a casing body is provided with a bolt limiting plate. When the automatic bolt-limited double-head door lock is locked, the bolt limiting hook can automatically limit the position of the set bar, and accordingly, a set bar limiting mechanism is formed. The utility model is the same as the existing double-head door lock, and has the advantages of simple structure, self-preservation at the time of the fall of the lock and convenient operation.
Description
The utility model belongs to the lock technology field, is a kind of inside and outside twin-lock head door lock that can limit bolt automatically.
Existing inside and outside double end door lock, its driving mechanism is to adopt screw key, by interior (outward) lock core, plectrum, transmitting gear, the gear plectrum carry-over bar drives the locking bolt advance and retreat.In order to limit the position of locking bolt, to reach the purpose of insurance, its limit bolt mechanism need continue screw key, by lock core, plectrum, rotates another gear (cam), and the locking bolt position is limited.Complex structure not only, and make troubles to user's operation, often occur having forgotten locking bolt is limit dead phenomenon.
The purpose of this utility model is a kind of twin-lock head door lock that can automatically the locking bolt position be limited simultaneously after locking of design.
Technical solution adopted in the utility model is improved on the basis of original inside and outside twin-lock head door lock, change plectrum into shifting block, remove two sleeve gear structures in original big lock housing, locking bolt after connect corresponding with shifting block is provided with group plate, as the locking bolt driving mechanism.On the locking bolt body, pin is set, sheathed limited bolt hook and elastic component (torsion spring) on the pin, limit bolt hook presses close to dial plate by suppressing of torsion spring.The big lock housing body in locking bolt next door is provided with limit bolt plate, the locking bolt lead is set on big lock housing body combines with gathering sill on the locking bolt, as limitting bolt mechanism, thereby constitutes automatic limit bolt double end door lock of the present utility model.
Because the utility model has been taked technique scheme, compare with existing twin-lock head door lock, when the locking bolt body advanced to locked position, limit bolt hook can enter in the bayonet socket of limit bolt plate automatically, thereby reach the effect of the self-insurance that latches, and have remarkable advantages such as simple in structure, easy to use.
Execute example below in conjunction with accompanying drawing and practicality, concrete structure of the present utility model is described further.
Fig. 1 represents Facad structure sectional view of the present utility model
Fig. 2 is the vertical view that removes base plate and outer tapered end.
As shown in Figure 1 and Figure 2, the utlity model has little lock housing 1, big lock housing 2, big lock shell plate 3, outer tapered end 4.Outer shifting block 5 is arranged on the inner face of big lock shell plate 3, and with the fastening binding of outer lock core, shifting block 5 has at least one shifting block.The first half of locking bolt body is a cylindricality locking bolt 10, and latter half of being equipped with dialled plate 6, dials plate 6 and is provided with at least one group mouth, dials mouth and is fan-shaped mouthful for good.Do not hold at group plate 6, be provided with pin 8, sheathed limited bolt hook 7 and torsion spring 9 on the pin 8, limit bolt hook 7 presses close to dial plate 6 by suppressing of torsion spring 9.The housing of the big lock housing 2 of locking bolt 10 1 sides is provided with limit bolt plate 15, offers limited bolt bayonet socket 14 on the limit bolt plate 15.Be provided with locking bolt gathering sill 13 on locking bolt 10, locking bolt gathering sill 13 is set on the lead 12 that is arranged on the housing.Referring to Fig. 2, inner lock head 11, internal cylinder and interior shifting block 5a are arranged on the housing of big shell 2, and its planform and outer tapered end 4, outer lock core are identical with outer shifting block 5.
During operation, screw key drives outer (or interior) lock core and shifting block 5 (or 5a) and rotates, and in the dialling mouthful of engaging-in group of plate 6 of shifting block 5 (or 5a), shifting block sees through to be dialled mouth and touch limit bolt hook 7, will limit bolt hook 7 tops from dialling plate 6, and the bayonet socket 14 that limit bolt hook 7 is thrown off limit bolt plates 15 limits.Shifting block 5 (or 5a) is rotated further, and shooting the lock-bolt 10 advances (falling back) when shifting block turns to locked position of coupler, and shifting block leaves dials plate, and limit bolt hook 7 falls into limit bolt bayonet socket 14 or is stuck in the edges at two ends of limitting bolt plate 15 at the pressure of torsion spring 9, and locking bolt 10 is limited insurance.
