Abstract

The utility model discloses a lock core with an engaging and disengaging device, and a poking fork device mounted at the tail end of the lock core. The lock core is characterized in that the tail end of the lock core is provided with a sliding block along the axial direction of the lock core, the sliding block is provided with an elastic element for driving the sliding block to move along the axial direction of the lock core, and mutually matching and locking parts are arranged between the poking fork and the slide. The lock core has the advantages that the connection locking relationship between the lock core and the poking fork is directly controlled by the insertion state of a key, the sliding block slides into the poking fork to drive the poking fork to make rotation when the key is inserted, the sliding block slides out of the poking fork under the action of the elastic element after the key is taken out, the poking fork and the lock core do not interlock, and the unlocking and locking of the lock can be controlled by other mechanisms.

Description

The lock core that has clutch

Technical field

The utility model relates in the lockset the improvement of lock core and lock bolt syndeton, a kind of specifically lock core that has clutch.

Background technology

Lockset of the prior art is by lock core, lock tube and be installed in locking mechanism in lock core, the lock tube and cooperate and to form, after locking mechanism unlocks, lock core can rotate in lock tube, drives the lock bolt motion when lock core rotates, and realizes the locking of lockset or the function of unblanking.All be by plectrum or gear drive usually between existing lock core and the lock bolt, when needing the motion of other control systems driving lock bolt, then require to remove the transmission between lock core and the lock bolt.

The utility model content

The purpose of this utility model is: provide a kind of simple in structure, can switch the lock core that has clutch of drive connection between lock core and lock bolt.

The technical solution of the utility model is:

A kind of lock core that has clutch, with the shift fork that is installed in lock core tail end place, it is characterized in that: be axially installed with a slide block along lock core at the lock core tail end, the flexible member that a driving sliding block is moved along the lock core axial direction is installed on the slide block, the part of the locking of cooperatively interacting is arranged between shift fork and slide block.

Supplementary technology scheme of the present utility model is:

Preferably, the described part that cooperatively interacts locking is that a space that cooperatively interacts with slide block is arranged on shift fork.

Preferably, described shift fork is a gear.

Preferably, described lock core and slide block are 2, symmetric arrangement, and shift fork is between 2 lock cores.

The beneficial effects of the utility model are: the connection locking relation between lock core and the shift fork is directly controlled by the insertion state of key, slide block slips into shift fork rotation in the shift fork when key inserts, after key is extracted, effect sliding block at flexible member skids off shift fork, shift fork and lock core no longer link, and the keying of lock can be by other auxiliary control section control.Whole lock structure is simple, and the control relation is reliable and stable.

Description of drawings

The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:

Fig. 1 is the schematic diagram of a specific embodiment of the utility model.

Fig. 2 is the schematic diagram of middle clutch part embodiment illustrated in fig. 1.

Fig. 3 is the schematic diagram that middle clutch part embodiment illustrated in fig. 1 and lock core are assembled together.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Specific embodiment of the utility model 1, as shown in Figure 1, a kind of lock core that has clutch, this lock core are installed in the lockset usually, the mode that adopts two cover lock cores to be oppositely arranged, and with the mutually combine keying of control gate of other electric control gears.This lock core 1, with the shift fork that is installed in lock core 1 tail end place, shift fork in this example adopts the form of gear 2, gear 2 cooperates the promotion lock bolt to move with the driving coupling part of lock bolt, be axially installed with a slide block 3 at the lock core tail end along lock core, the flexible member 4 of a driving sliding block to the motion of lock core direction is installed on the slide block 3, lock core 1 in this example and slide block 3 be not symmetry installation all, as shown in Figure 2, slide block 3 is installed on the same slide block connecting axle 5, the part that the locking of cooperatively interacting is arranged between shift fork and slide block, slide block slips into shift fork rotation in the shift fork when key inserts, and after key is extracted, skids off shift fork at flexible member effect sliding block, shift fork and lock core no longer link, and the keying of lock can be controlled by other controlling organizations.

In the above-described embodiments lock core 1 and slide block 2 also can be done monolateral setting, and a cover lock core and a slide block promptly only is set.Those skilled in the art can also can carry out various designs according to actual needs to the concrete form of the shift fork in the foregoing description, slider part.

Disclosed all features in this manual, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.

Disclosed arbitrary feature in this manual (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
