Detailed description of the invention
Describe below in conjunction with accompanying drawing and specific embodiment.
Embodiment 1
Referring to Fig. 1 to Fig. 6.The described closed solid bodies lock core of the present embodiment, by housing 1, unlock chip 2, only locking plate 3, dead bolt 4, pedestal 5 and elastomeric element form.
Housing 1 is rectangular structure, hollow, and its front is provided with multiple the first keyholes 11, and an one side is provided with a dead bolt and portals 12.Multiple the first keyholes 11 are evenly arranged in a row, in the present embodiment, show the situation that six the first keyholes 11 are set, can certainly be arranged to other different numbers, theoretically, according to the structure of the present embodiment lock core, the number of the first keyhole is more, and the security performance of lock core is higher.
On pedestal 5, be provided with multiple locking plate chutes 51 and a dead bolt chute 52, locking plate chute 51 and dead bolt chute 52 parts are arranged in a crossed manner.As preferably, locking plate chute 51 is vertical with dead bolt chute 52 and part is crossing.The quantity of locking plate chute 51 is identical with the quantity of the first keyhole 11, and locking plate chute 51 and the first keyhole 11 run through.In the present embodiment, locking plate chute 51 is positioned at the bottom of pedestal 5, and its bottom lock forms a rectangular through-hole; Dead bolt chute 52 is positioned at the top of pedestal 5, and this dead bolt chute 52 runs through pedestal 5 completely, and open top.The top cross of the bottom of dead bolt chute 52 and locking plate chute 51 is staggered.
Each locking plate chute 51 is interior to be all equipped with a unlock chip 2 and to stop locking plate 3, and only locking plate 3 is between unlock chip 2 and dead bolt 4.
In the present embodiment, the concrete structure of unlock chip 2 is: be made up of first substrate 21 and unlock chip limiting plate 22, first substrate 21 is mutually vertical with unlock chip limiting plate 22, and Fig. 5 shows a kind of unlock chip of L shaped structure, certainly can be designed as ⊥ shape structure.
In the present embodiment, only the concrete structure of locking plate 3 is: have second substrate 31 and support plate 33 to form, second substrate 31 is rectangle, and one side of second substrate 31 is connected with support plate 33, is provided with notch 32 on one side relative with this limit.
Unlock chip limiting plate 22 is connected with support plate 33 contacts, unlock chip limiting plate 22 is equipped with i.e. the first elastomeric element and the second elastomeric element of elastomeric element with support plate 33 both sides, in the present embodiment, the first elastomeric element is that the first spring 23, the second elastomeric elements are the second spring 34.Specifically, the first spring 23 is arranged between housing and unlock chip limiting plate 22, the second spring 34 is arranged between housing and support plate 33, the axial line of the first spring 23 and the second spring 34 is located along the same line, and is conducive to like this keep equilibrium of forces, keeps unlock chip limiting plate 22 and support plate 33 in sliding process, to keep balance.The in the situation that of the first spring and the second spring force balance, the notch 32 respectively stopping on locking plate 3 is interspersed.
In dead bolt chute 52, be equipped with dead bolt 4, dead bolt 4 is strip, main body is cuboid, its outside of belly is provided with groove 41, the back side is provided with projection 42, the 3rd spring 44 is assemblied between projection 42 and inner walls, and the opposite side of projection 42 has a limited post 13, and described limited post is arranged on housing 1 inwall or in dead bolt chute 52.The elastic force direction of the 3rd spring 44 is parallel with dead bolt, namely parallel with the direction of motion of dead bolt 4.Dead bolt chute 52 lower shapes are identical with the shape of notch 32, and complete when overlapping when notch 32 and dead bolt chute 52, dead bolt 4 could be in the interior without hindrance slip of dead bolt chute 52.
Use as lock core, the outer end of dead bolt 4 is set to horizontal top 43a, or addendum cone.Described in the present embodiment, horizontal top 43a refers to so a kind of structure: top and bottom are inclined-plane, as the prism of same horizontal placement.
For further improving security performance, can be by setting up an auxiliary pellet module 7, this auxiliary pellet module 7 is sticked on housing 1, namely helps pellet module 7 and housing 1 split setting.In pellet module 7, be provided with multiple through holes 71 corresponding with the first keyhole 11, when assembling, the first keyhole 11 is connected with through hole 71, and key can correctly be inserted.
For ease of key more convenient and quicker insert in through hole 71 and the first keyhole 11, in auxiliary pellet module 7, a groove 72 is set, through hole 71 is positioned at the bottom of this groove 72.This groove can be set to rectangular recess, trapezoidal groove or arc groove.
Embodiment 2
Referring to Fig. 7.The described lock of the present embodiment, the structure of lock core is basic identical described in basic structure and embodiment 1, below only difference is described.
As different from Example 1, the outer end of dead bolt 4 is set to vertical top 43b, instead of horizontal top; Vertical top 43b is as the prism of same vertical placement.Vertical top 43b comprises two vertical planes, and two vertical planes extend compared to a straight line, and this straight line is positioned on the plane of symmetry of dead bolt 4.
Can both unblank for ease of the both sides at door, with the first keyhole 11 accordingly, be provided with six the second keyhole 14, the second keyholes 14 and the first keyhole 11 on two relative faces at the back side of housing 1.
For the working method of lock core in above-mentioned two embodiment or lock is more clearly described, below in conjunction with describing with lock core or the phase-locked key mating, the present embodiment provides a kind of key, as shown in Figure 8.This key 6 is a rectangle plate, certainly, can also be designed to other shapes for attractive in appearance, with the first keyhole 11 adaptably, on a limit of key 6, be provided with six fore-sets 61, the length of all fore-sets is unequal or not exclusively equal.While unblanking, fore-set 61 is inserted to the first keyhole, withstand and promote unlock chip 2, the first spring is compressed by 23, under the elastic force effect of the second spring 34, only jam plate is subjected to displacement, the notch 32 being finally interspersed overlaps with dead bolt chute 52, dead bolt 4 just can without hindrance slip in lock is established chute, and dead bolt 4, in elastic force or the External Force Acting lower slider of the 3rd spring 44, takes out key, in the time that the groove 41 on dead bolt overlaps again with locking plate chute 51, under the effect of the first spring and the second spring, only locking plate and unlock chip reset, and dead bolt is again by locking.The design of vertical top 43b is to insert under the state of key, while pulling, utilizes vertical top 43b and the active force between doorframe lockhole to make dead bolt slip.
The key that the key principle being used in conjunction with from the second keyhole 14 and the first keyhole are used in conjunction with is all different, with this understanding, unlock chip can use steel, withstanding of key used magnetic material to make, as magnet, attract unlock chip to break the dynamic balance between the first spring and the second spring by magneticaction, notch 32 is overlapped with dead bolt chute 52.
Below be only preferred embodiment of the present utility model, it should be pointed out that above-mentioned preferred embodiment 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 limited range.For those skilled in the art, not departing 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.
