Description

Cylinder lock with balls

Technical field

The present invention relates to mechanical lock, particularly a kind of cylinder lock with balls.

Background technology

Cylinder lock with balls is common lockset, and typical structure comprises the parts such as lock housing, lock core, lock pearl, face pearl.As shown in Figure 1, lock pearl 3 enters the hole of bead or face pearl 4 when entering the other side hole of bead, and lock core 2 lockings can not be in lock housing 1 interior rotation; When keyhole 22 interior insertion key, lock pearl 3 or face pearl 4 breaks away from the other side hole of beads, and lock core 2 can be in lock housing 1 interior rotation, thereby lockset is opened.There is following defective in this cylinder lock with balls:

One is to insert spoon and pull out spoon inconvenience.As shown in Figure 2, the hole of bead of lock core 2 is difficult to aim at fully with the hole of bead of lock housing 1, and this be so that lock pearl 3 or face pearl 4 can not normally enter the other side hole of bead, thereby causes inserting spoon and pull out spoon not smooth.

Its two, be that lock core rotates underaction.As shown in Figure 3, if lock pearl 3 can cause locking pearl 3 and touch lock housing 1 inwall than lock core 2 peripheral protrusions, this can make lock core rotate inconvenience.Such as forced rotating lock core 2, lockset will be damaged.

Its three, be that safety is relatively poor.Promotion face pearl 4 or lock pearl 3, with regard to the energy rotational lock core, there is the high risk of key mutual opening rate in this, so that lockset loses anti-theft function.

Summary of the invention

In view of this, the invention provides a kind of cylinder lock with balls easy to use, safe.

For solving above technical problem, technical scheme of the present invention is: a kind of cylinder lock with balls comprises lock housing (1) and is installed on the interior lock core (2) of described lock housing (1); Described lock core (2) radially offer the hole of bead (21), lock pearl (3) and lock pearl reposition element wherein are set; Described lock core (2) vertically offer keyhole (22), its teeth groove (221) is communicated with the described hole of bead (21); Described lock core (2) is offered lateral plate groove (23), and the inwall of described lock housing (1) is offered two lock housing grooves (11), and described lock pearl (3) is offered lock pearl groove (31); Movable lateral plate (6) is set in the described lateral plate groove (23), and its two ends are movable to lock housing groove (11) and described lock pearl groove (31); The described hole of bead (21) is a plurality of, along axially being arranged in a row of described lock core (2).

In the described lateral plate groove (23) the lateral plate reposition element is set.

Described lock pearl back-moving spring (5) is arranged on the outside of the described hole of bead (21).

Described keyhole (22) laterally is opened in an end in the described hole of bead (21), and its teeth groove (221) is positioned at the middle part of described keyhole (22).

Described keyhole (22) arranges respectively key gathering sill (222) in the both sides of described teeth groove (221).

Compared with prior art, cylinder lock with balls of the present invention arranges lock pearl and lateral plate simultaneously in lock core, and both cooperate controlled lockmaking tool to unblank/locking, have advantages of practical and convenient, safe.Especially, exclusive keyhole design so that key is difficult for being replicated, further improves the theftproof performance of lockset.

The specific embodiment

Basic conception of the present invention is, lock pearl and lateral plate are set in the lock core simultaneously, and both cooperate the control lockset to unblank/locking.

Specify below in conjunction with accompanying drawing and embodiment.

Simultaneously referring to Fig. 4, Fig. 5, cylinder lock with balls of the present invention comprises lock housing 1 and is installed on lock core 2 in the lock housing 1, wherein lock core 2 radially offer the hole of bead 21, lock pearl 3 and lock pearl back-moving spring 5 wherein are set; Vertically offer keyhole 22, its teeth groove 221 is communicated with the hole of bead 21, especially:

Lock core 2 is offered lateral plate groove 23, and its inside arranges movable lateral plate 6;

Simultaneously, the inwall of lock housing 1 is offered two lock housing grooves 11, the corresponding lock pearl groove 31 of offering of lock pearl 3 inwalls, and so that movable lateral plate 6 two ends are movable to lock housing groove 11 and lock pearl groove 31.

In addition, can lateral plate reposition element such as spring be set lateral plate groove 23 is interior, so that lateral plate 6 reliable and stable motions.Thus, by cooperating of lock pearl 3 and lateral plate 6, the rotation of control lock core 2, and then control the switching of lockset/lock.

The hole of bead 21 is a plurality of in the present embodiment, along axially being arranged in a row of lock core 2; Lock pearl back-moving spring 5 is arranged on the outside in the hole of bead 21, so that lock pearl 3 presses to keyhole 22.

Such as Fig. 4, shown in Figure 5, keyhole 22 is optimal design in the following manner: keyhole 22 laterally is opened in an end in the hole of bead 21, namely with the hole of bead 21 arranged crosswise; Teeth groove 221 is positioned at the middle part of keyhole 22, the shape such as that cross sectional shape can be is trapezoidal, rectangle, triangle; Teeth groove 221 both sides arrange respectively key gathering sill 222, adopt the right-angled trapezium uniform section, convenient key and the location of importing.

Corresponding with teeth groove 221 in the keyhole 22, the shape of gathering sill 222, position, need at the key middle part key bit is set, and in its both sides guide rail is set.This key in market difficulty copy, be conducive to improve the theftproof performance of lockset.

The opening of cylinder lock with balls of the present invention/locking process is: when original key injects keyhole 22, lock pearl 3 middle parts lock pearl groove 31 shapes in line, slightly rotational lock core 2, lateral plate 6 is subject to that lock housing 1 inwall promotes and the groove position of inserting lock pearl 1 middle part, this rear lock core 2 can flexible rotatings; The key that does not match such as use inserts keyhole 22, and the groove position of lock pearl 3 can be not in line, even rotational lock core 1, lateral plate 6 can not insert this groove position yet, and only can withstand the lock housing groove 11 of lock housing 1 inwall, thereby so that lock core 2 loses rotating function, improve the theftproof performance of lockset.

Above-mentioned cylinder lock with balls can be in multiple occasion, for example the blade drawer-lock of furniture.The traditional blades drawer-lock exist to insert spoon not smoothly, mutual opening rate is high, insert spoon without drawbacks such as feels, adopts hoodle drawer-lock of the present invention then can overcome the above problems, its security reliability is high, can satisfy high-quality, the high-caliber life seek of modern.

Only be preferred embodiment of the present invention below, should be pointed out that above-mentioned preferred embodiment should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with the claim limited range.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
