Description

The vane type tapered end

Technical field

The utility model relates to a kind of safe-guard door lock tapered end that is equipped with some blades.

Background technology

Safe-guard door lock is to utilize key to be inserted in the keyhole set on the tapered end when realizing opening, and under the drive of key, realizes the action of relevant locking bolt in the safe-guard door lock.Tapered end is as a vitals in the safe-guard door lock, and the quality of the anti-technical unlocking of tapered end directly has influence on the safety of safe-guard door lock.The tapered end of existing safe-guard door lock is to adopt to have differential pellet shot from a slingshot and limit the rotation of lock core in tapered end, the weak effect of the anti-technical unlocking of this tapered end mostly.For improving the theftproof performance of safe-guard door lock, the tapered end that has also occurred vane type now on the market, promptly be perpendicular to the some container cavities of being axially arranged with of lock core in the lock core upper edge, be provided with a slice blade in each container cavity, blade can be movable in container cavity, container cavity communicates with keyhole, and blade is provided with convex body, be provided with on the inwall of lock core hole be used for blade on the convex body draw-in groove of clamping mutually.After in key is inserted into keyhole, under the promotion of key, blade belongs to the enable possition, and promptly blade is positioned at lock core inside fully, and the convex body on the blade can not snap fit onto in the described draw-in groove.The tapered end of this structure is prevented the effective of technical unlocking.But keyhole is the medium position place that is positioned at lock core, and keyhole just communicates with the outer peripheral face of lock core in described container cavity position.This keyhole generally can only adopt the mode of punching press to process, and processing is inconvenient, and can not be guaranteed to the machining accuracy of keyhole.

The utility model content

For overcoming above-mentioned defective, the purpose of this utility model is: a kind of vane type tapered end simple in structure, easy to process is provided.

Reach the technical measures that institute's purpose is taked: a kind of vane type tapered end, comprise tapered end and lock core, be provided with lock core hole in the tapered end, lock core is inserted in the lock core hole rotationally, lock core inside is axially arranged with keyhole along it, the edge is provided with some container cavities perpendicular to the lock core axial direction in lock core, be provided with mobilizable blade in the container cavity, container cavity communicates with keyhole, be provided with on the lock core hole inwall be used for blade on the set convex body draw-in groove of clamping mutually, described keyhole is the open slot that is formed on the lock core, and the aperture position of this open slot is positioned on the outer peripheral face of lock core.

Described blade is " several " shape, and the openend of blade is towards keyhole.

Described convex body lays respectively at the blind end of blade and the position of openend both sides.

Between lock core and blade, be provided with and impel the spring of blade towards the keyhole internal motion.

This reality is novel to have following effect:

Keyhole is the open slot that is formed on the lock core, the position of this open slot is positioned on the outer peripheral face of lock core, in the man-hour that adds of realizing keyhole, can adopt the processing method of milling to process, with respect to impact style, the processing of being more convenient for of the keyhole of this structure, and the machining accuracy of keyhole also can be guaranteed, and guaranteed the grafting smoothness between key and the keyhole.

Description of drawings

Fig. 1 is the transverse sectional view of this vane type tapered end in the container cavity position.

Fig. 2 is that this vane type tapered end is in the transverse sectional view that makes under the state.

Fig. 3 is the structural representation of blade in this vane type tapered end.

Fig. 4 is the structural representation that is used for the key that matches with this vane type tapered end.

The specific embodiment

The structure of this vane type tapered end comprises tapered end 1 and lock core 2, is provided with lock core hole in the tapered end 1, and lock core 2 is plugged in the lock core hole, and lock core 2 can rotate in lock core hole.Be axially arranged with keyhole 7 along it in the lock core 2, keyhole 7 is an open slot that is formed on the lock core 2, and the aperture position of this open slot is positioned on the outer peripheral face of lock core 2.

On the direction axial of lock core 2 upper edges, be provided with some container cavities 5 perpendicular to it, container cavity 5 communicates with keyhole 7, these container cavities 5 are provided with a slice blade 6 along the axially spaced-apart setting of lock core 2 in each container cavity 5, blade 6 can be movable in container cavity 5.Blade 6 is " several " shape, thereby makes blade 6 be formed with openend and blind end, and blade 6 is horizontal and is arranged in the container cavity 5, is equipped with the convex body 3 that stretches out in blade 6 openend both sides and blade 6 blind end places, and these convex bodys 3 are connected as a single entity with blade 6.Lock core hole inwall upper edge in tapered end 1 its axially respectively the compartment of terrain be provided with three clamp bar slots 4, the appearance and size of all blades 6 is all identical, the position of three convex bodys 3 of this three clamp bar slot 4 on the position on the lock core hole inwall and blade 6 is corresponding, and three convex bodys 3 on the blade 6 can be connected to respectively in three draw-in grooves 4.The size of container cavity 5 should equal the appearance and size of blade 6 at least, and blade 6 can be contained in when opening in separately the container cavity 5 fully, and can not have influence on the rotation of lock core 2 in lock core hole.Just distinguish to some extent at the width at its blind end place between the different blades 6, the side of key 9 is made into curved, and after key 9 was inserted in the keyhole 7, key 9 these sides contacted with the inner side edge of blade 6 blind ends, thereby blade 6 is limited to open position.

Be provided with spring 8 between lock core 2 and blade 6, the two ends of this spring 8 act on respectively on lock core 2 and the blade 6, and spring 8 has and impels the trend of blade 6 towards keyhole 7 internal motions.After in key 9 is inserted into keyhole 7, under the acting in conjunction of key 9 and spring 8, blade 6 can stably remain on the position of unlatching, and after extracting key 9, under the effect of this spring 8, the openend of blade 6 can reach the outside of lock core 2 outer peripheral faces, and snaps fit onto in the above-mentioned draw-in groove 4, and blade can participate in the qualification that lock core 2 is rotated 6 this moments.

Blade 6 is " several " shape, and is simple in structure.After key 9 was plugged in the keyhole 7, key 9 was plugged in the blade 6 simultaneously, and the contact stabilization between key 9 and the blade 6 is good, only needed the side of a key 9 to make curve-like, thereby also can effectively simplify the structure of key 9, was convenient to key 9 is processed.
