Abstract
A locking head with a bifunctional clip relates to locks belonging to articles for daily use and comprises a key provided with a clip supporting bit, a locking head body, a pipe-shaped lock pin arranged in the locking head body, upper and lower clips correspondingly arranged between the locking head body and the lock pin, a spacing pin arranged in the locking head body and a spacing groove which is corresponding to the spacing pin and arranged on the lock pin. The utility model is characterized in that the key is a pipe-shaped key, the clip supporting bit on the forefront of the key is a keyway clip supporting bit, the lock pin is a pipe-shaped lock pin which is provide with the bifunctional clip at the position corresponding to the keyway clip supporting bit, and the center of the lock pin is provided with a lock pin shaft matching the inner diameter of the pipe-shaped key. The technical burglarproof ability of the lock is remarkably improved, and thereby the utility model can replace various prior clip locking heads to produce various locks.
Description
Technical field
The utility model relates to the lockset in the daily living article.What be particularly related to is a kind of cylinder type tapered end of mechanical lockset.
Background technology
Existing ball lock head is mostly accepted the key of tartar, tapered end body, is located at the lock core in the tapered end body and corresponding is arranged on the upper and lower pellet shot from a slingshot between tapered end body and the lock core and spacer pin and the corresponding stopper slot that is arranged on the lock core that is located on the tapered end body constituted by having pellet shot from a slingshot.By pellet shot from a slingshot on the key accept tartar will match the other end pushing tow of the following pellet shot from a slingshot in lock core be moved to the tangent station of lock core external diameter on separate its locking, again by on the key and boss between lock core or groove fit, key reversed to drive lock core and rotate and lock is opened.The shortcoming of this ball lock head is that the lock core space is big, is opened thoroughly with master key by the lawless person easily.
The utility model content
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, and a kind of tapered end with difunctional pellet shot from a slingshot is provided, and the lock core space of this tapered end is narrow and small, and the instrument that can limit master key and so on effectively inserts into the inner and prevents technical unlocking.
Realize the tapered end with difunctional pellet shot from a slingshot of the utility model purpose, comprise and be provided with the key that pellet shot from a slingshot is accepted tartar, the tapered end body, be arranged in the tapered end body pipe shape lock core and corresponding be arranged between tapered end body and the lock core on, following pellet shot from a slingshot, be arranged on the spacer pin in the tapered end body and be arranged on stopper slot on the lock core corresponding to this spacer pin, described key is a pipe shape key, it is that a keyway formula pellet shot from a slingshot is accepted tartar that the pellet shot from a slingshot foremost of key is accepted tartar, described lock core is a pipe shape lock core, accepting the pairing position of tartar with this keyway formula pellet shot from a slingshot and being provided with a difunctional pellet shot from a slingshot of lock core also is provided with a lock core shaft that matches with the internal diameter of pipe shape key on the center of lock core.Pipe shape key inserts in the lock core hole and is socketed in the lock core shaft when unblanking, when putting in place and a keyway formula pellet shot from a slingshot end of accepting the pairing difunctional pellet shot from a slingshot of the tartar keyway formula pellet shot from a slingshot that is moved to key accept in the tartar, the other end be positioned at the tangent release station of the external diameter of lock core on, other pellet shot from a slingshot in the tapered end is the same with common spring, when key is inserted into, accepted by the pellet shot from a slingshot of key tartar be moved to the tangent release station of the external diameter of lock core on.Key is accepted the difunctional pellet shot from a slingshot driving torque of tartar by being arranged in keyway formula pellet shot from a slingshot, thereby the drive lock core rotates with respect to the tapered end body and will lock unlatching.Go back to the key back that puts in place and extract key out, each pellet shot from a slingshot stretches out apical grafting in lock core shaft to lock core under the effect of marble spring, and promptly each pellet shot from a slingshot is in the locking station, will lock.Because lock core shaft has occupied the big portion space in the lock core, therefore be difficult to put in the inner end of dark plant pipe shape lock core with the skilled unlocking instrument of master key and so on, stir the difunctional pellet shot from a slingshot that is in the inner end of lock core and make it to overcome spring pressure and be moved to the release station, also will make it to drive lock core simultaneously and rotate then difficulty more--promptly do not have enough spaces to reach the standard of the release displacement of difunctional pellet shot from a slingshot in the-lock core, the lock core of pipe shape does not have the boss groove to rotate for the unlocking tool power of taking yet.
Compared with the aforementioned existing similar products, the utility model has the advantages that by difunctional pellet shot from a slingshot and when being in the release station, also serve as the effect of transmitting the key moment of torsion, thereby lock core and key all are set to the pipe shape, eliminated the condition of unblanking as the skilled unlocking instrument of master key and so on, improved the performance of the anti-technical pirate of the open of lockset greatly, alternative existing various ball lock head uses become various locksets.
Below in conjunction with drawings and Examples content of the present utility model is done further explanation, but content of the present utility model is not limited only to content related among the embodiment.

The specific embodiment
Shown in Fig. 1～6, originally the formation that has the tapered end of difunctional pellet shot from a slingshot comprises and is provided with the key 3 that pellet shot from a slingshot is accepted tartar, tapered end body 1, be arranged in the tapered end body 1 pipe shape lock core 2 and corresponding be arranged between tapered end body and the lock core on, following pellet shot from a slingshot 8,9, be arranged on the spacer pin 10 in the tapered end body and be arranged on stopper slot 11 on the lock core corresponding to this spacer pin, described key is a pipe shape key, referring to Fig. 7～8, it is that a keyway formula pellet shot from a slingshot is accepted tartar that the pellet shot from a slingshot foremost of key is accepted tartar 12, described lock core is a pipe shape lock core, accepting the pairing position of tartar with this keyway formula pellet shot from a slingshot and being provided with a difunctional pellet shot from a slingshot 5 of lock core also is provided with a lock core shaft 4 that matches with the internal diameter of pipe shape key 3 on the center of lock core.Above-mentioned each parts with and the structural relation form that all can use existing ball lock head.A station figure of each parts when Fig. 2 has provided key and is inserted into, this moment, the one end keyway formula pellet shot from a slingshot that is arranged in key under the effect of spring 7 of difunctional pellet shot from a slingshot 5 was accepted tartar 12, its other end be positioned at the external diameter of lock core 2 tangent release station on; Other pellet shot from a slingshot in the tapered end (only indicating pellet shot from a slingshot 8,9,6 among the figure) is the same with common spring, is in the release station when key puts in place.Key 3, keyway formula pellet shot from a slingshot are accepted tartar 12 and are driven difunctional pellet shot from a slingshot 5 and rotate, difunctional pellet shot from a slingshot 5 drive lock cores 2 with respect to tapered end body 1 rotate the angle [alpha] of unblanking to Fig. 5, shown in Figure 6 unblank station and finish and unblank.
