Description

Cylinder lock with balls

Technical field

The utility model 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 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 rotated in lock housing 1; When inserting key in keyhole 22, lock pearl 3 or face pearl 4 break away from the other side hole of bead, and lock core 2 can rotate in lock housing 1, 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 makes 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.As rotational lock core 2 by force, 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, makes lockset lose antitheft effect.

The utility model content

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

For solving above technical problem, the technical solution of the utility model 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 lock housing groove (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).

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

The described hole of bead (21) is a plurality of, along axially being arranged in a row of described lock core (2).

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) is provided with key gathering sill (222) respectively in the both sides of described teeth groove (221).

Compared with prior art, the utility model cylinder lock with balls is provided with lock pearl and lateral plate simultaneously in lock core, but both cooperate the control lock tool to unblank/locking, have practical and convenient, safe advantage.Especially, exclusive keyhole design makes that key is difficult for being replicated, and further improves the theftproof performance of lockset.

The specific embodiment

Basic design of the present utility model 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, the utility model cylinder lock with balls 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 is provided with movable lateral plate 6;

Simultaneously, the inwall of lock housing 1 is offered lock housing groove 11, and lock pearl 3 inwalls are corresponding offers lock pearl groove 31, and makes movable lateral plate 6 two ends be movable to lock housing groove 11 and lock pearl groove 31.

In addition, can lateral plate reposition element such as spring be set in lateral plate groove 23, make 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/lock of lockset.

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, makes lock pearl 3 press to keyhole 22.

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, promptly with the hole of bead 21 arranged crosswise; Teeth groove 221 is positioned at the middle part of keyhole 22, shape such as that cross sectional shape can be is trapezoidal, rectangle, triangle; Teeth groove 221 both sides are provided with key gathering sill 222 respectively, 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 key bit is set, and guide rail is set in its both sides at the key middle part.This key in market difficulty duplicate, help improving the theftproof performance of lockset.

The opening of the utility model cylinder lock with balls/locking process is: when original key injects keyhole 22, lock pearl 3 middle parts lock pearl groove 31 forms a straight line, rotational lock core 2 slightly, and lateral plate 6 is subjected to lock housing 1 inwall and promotes and insert the groove position of locking pearl 1 middle part, and this rear lock core 2 can rotate flexibly; The key that does not match 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, thus make lock core 2 lose 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.There is drawbacks such as inserting spoon is freely not suitable, mutual opening rate is high, the no feel of slotting spoon in the traditional blades drawer-lock, adopts the utility model hoodle drawer-lock then can overcome the above problems, and its security reliability height can satisfy high-quality, the high-caliber life seek of modern.

Only be preferred implementation of the present utility model below, should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim institute restricted portion.For those skilled in the art, in not breaking away from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
