Hereinafter, illustrative embodiments according to the present utility model are described with reference to the accompanying drawings.

Fig. 1 shows a kind of lock 100.In Fig. 1, lock 100 is in assembled state, and has key 200 to be inserted.In order to For the sake of clear, the other component of lock 100 is eliminated in attached drawing, for example, the installation group for 100 installations to door (not shown) will to be locked Part.

As shown in Figure 1, in this embodiment, lock 100 is locked for modularization, lock core module 110, handle gallbladder mould are generallyd include Block 120 and extension module 130.

The exploded perspective view of lock shown in Fig. 1 is shown in Fig. 2.As shown in Fig. 2, lock 100, which has, is located at middle section Dial core 300 and pulling sleeve 301.To dial that core 300 and pulling sleeve 301 are circumferential to be engaged as known in the art, dial core 300 and 111 axial engagement of lock core in lock core module 110 so that pulling sleeve 301 with dial core 300 rotation and rotate, thus open and Lock door.

Lock core module 110 has lock core 111 and the first receptacle 112.Lock core 111 is located at the circle of 110 lower part of lock core module It in cylindrical section 113, and is rotated with the rotation of key 200, to play the role of actuated piece.First receptacle 112 is located at The top of lock core module 110, specifically, the first receptacle 112 are groove open upwards, and the groove is in lock core module 110 , also open on opposite with key 200 side.

One end of handle gallbladder module 120 is located at the other side of door, that is, indoor, for being engaged with handle component.Handle gallbladder Module 120 has the second receptacle 121.Second receptacle 121 is located at the top of handle gallbladder module 110, and specifically, second connects Portion 121 is received as groove open upwards, which also opens on handle gallbladder module 110, opposite with handle component side.

Extend module 130 to be located between lock core module 110 and handle gallbladder module 120, and including extension 131 and fixed part 140。

There is extension 131 first extending sleeve 132 and first to extend core 133, and the first extension core 133 is located at the first extending sleeve In 132, the first extending sleeve 132 is not circumferentially engaged with the first extension core 133, is turned due to without rotating with the first extension core 133 It is dynamic.

Fixed part 140 has stationary body part 134 and fixing piece 135.

In the present embodiment, the first extension core 133 is engaged with lock core 111 to rotate with it, and first extends core 133 and dial Core 300 is axially aligned and is engaged with common rotation.

The both ends of stationary body part 134 are respectively accommodated in the first receptacle 112 and the second receptacle 121, and by solid Determine through-hole 136 of the part 135 in the stationary body part 134 and is individually secured to the first receptacle 112, the second receptacle 121 and the In one extending sleeve 132.

In the present embodiment, the cross section of the groove of the first receptacle 112 and the second receptacle 121 and stationary body part The cross section of 134 end is corresponding.

First receptacle 112, the second receptacle 121 and the first extending sleeve 132 have fixation hole 139 to receive fixing piece 135.In the present embodiment, fixation hole 139 is threaded hole, and fixing piece 135 is screw.

An embodiment according to the present utility model, extension 131 further include that the second extending sleeve 137 and second extends core 138.Second extension core 138 is located in the second extending sleeve 137.Second extending sleeve 137 does not extend core 138 with second and rotates.Second Extending sleeve 137 is located at the first extending sleeve 132 and dials between core 300.The thickness of second extending sleeve 137 and the first extending sleeve 132 Thickness is different.

Second extension core 138 is axially aligned with the first extension core 133, group core 300 and is engaged with common rotation.

First extending sleeve 132 and the second extending sleeve 137 are provided with the groove for accommodating the end of stationary body part 134 at top 141, the cross section of the groove 141 is corresponding with the cross section of the end of stationary body part 134.

In the respective embodiments described above, extend module 130 outer profile after assembling with 111 module of lock core and handle gallbladder mould The outer profile of block 120 is concordant.

According to the utility model, extend the length of module 130 by changing extending sleeve and the number for extending core in extension 131 Amount and width and can be changed, thus changeable the distance between 111 module 110 of lock core and handle gallbladder module 120, so that change is entirely The thickness of lock 100, so that the door for being suitable for various thickness applies difference to improve versatility so as to avoid to different doors Lock.

In addition, since lockset according to the present utility model uses modularized design, thus using the alterable place of a set of lockset Multiple combinations, improve universal, and can also reduce inventory.

In addition, user can be used general fastening tool come tool oneself need realizing self disassembling assembling extend module, behaviour Make simple, the saving operating time.

Although the utility model is illustrated in detail and described above by reference to illustrative embodiments, this field is common It will be appreciated by the skilled person that above embodiment is solely for the purpose of illustration and the example lifted, rather than be used to limit this The range of application.Scope of the present application by by the appended claims and its any and all equivalent, including its feature Any combination of full width provides.It, can be practical to this in the case where not departing from the spirit and scope such as the utility model Novel a variety of various forms and details are changed.
