Embodiment

In order to which the technical characteristics of the utility model, purpose and effect are more clearly understood, it is detailed now to compare accompanying drawing Illustrate specific embodiment of the present utility model.It is to be appreciated that in the description of this specification, the orientation or position of instruction Relation is based on orientation shown in the drawings or position relationship, is for only for ease of description the utility model and simplifies description, without It is instruction or implies that signified device or element there must be specific orientation, with specific azimuth configuration and operation, therefore not It is understood that as to limitation of the present utility model.Therefore, " top " and " bottom " can with " top " and " bottom ", " first " and Equivalence replacements such as " second ", " left side " and " right side ".

As shown in figs. 1-7, a kind of Multi-point lockikng mechanism, including multiple latch hooks 100, multiple locking plates 200 and drive mechanism 300, drive mechanism 300 drives the latch hook 100 or locking plate 200 to move up and down, latch hook 100 and locking plate 200 matches and position Put corresponding.Locking plate 200 is arranged on a side door plate or shell, and latch hook 100 is arranged on the door-plate or shell of opposite side.Drive Motivation structure 300 moves up and down or driven locking plate 200 to move up and down with moveable lock hook 100, when latch hook 100 leans on respect to locking plate 200 After near, latch hook 100 catches on locking plate 200, and Multi-point lockikng mechanism is lockable；After latch hook 100 is remote with respect to locking plate 200, Latch hook 100 departs from locking plate 200, and Multi-point lockikng mechanism can unlock.

The utility model is applied to new blower fan, the door hinge mechanism of air purifier product class, by setting multiple latch hooks 100 and multiple locking plates 200 coordinate, realize multi-point fastening, close door-plate or shell post gap is uniform, exquisite appearance, sealing effect Fruit is good.One key can control multi-point fastening or unblock simultaneously, easy to operate, securely and reliably.

Embodiment 1

Drive mechanism 300 drives locking plate 200 to move up and down.

Specifically, as depicted in figs. 1 and 2, drive mechanism 300 is fixed on the first shell 410 vertically, specifically, fixed In the side of the first shell 410, including locking bar 310, locking plate 320 and lock core 330.

As shown in Figures 2 and 3, the generally strip of locking bar 310, including main body 311, the hole 313 of gangbar 312 and first. Main body 311 is the tabular of strip, and side is fixed with multiple locking plates 200.Gangbar 312 is protrusively provided on the surface of locking bar 310, Direction is vertical with main body 311.The first hole 313 is offered in main body 311, the first hole 313 is arranged on gangbar 312 in the present embodiment Top, the first hole 313 is waist-shaped hole.

As shown in Fig. 3, Fig. 6 and Fig. 7, lock core 330 is fixed on the first shell 410 close to one end of lockhole 331, the other end It is fixedly connected with locking plate 320.It is fixed such as in the present embodiment, lock core 330 is fixedly connected by fixing nut 332 with locking plate 320 Nut 332 moves up and down in the first hole 313.When key, which is inserted in lockhole 331, to be rotated, lock core 330 drives locking plate 320 with solid Determine nut 332 to rotate back and forth for axle.

As shown in figure 4, locking plate 320 has eccentric structure, it is overall substantially to pass through fixed spiral shell in sector, the substantially position in the center of circle Mother 332 is fixedly connected with lock core 330, and eccentric orfice 321 is offered along the direction bias of arc.Specifically, eccentric orfice 321 is arc-shaped Waist-shaped hole, two end points of eccentric orfice 321 are respectively short end 321a and long end 321b, and short end 321a is to fixing nut 332 Distance be less than long end 321b to fixing nut 332 distance.The gangbar 312 of eccentric orfice 321 and locking bar 310 matches, connection Lever 312 passes through eccentric orfice 321, and can be slidably reciprocated in eccentric orfice 321, drives main body 311 to move up and down, and then drives Locking plate 200 moves up and down in main body 311.

As shown in Fig. 2 locking plate 200 is substantially in " T " font that side is put, the side of main body 311, including recess are fixed on 210 and limiting plate 220, locking plate 200 and latch hook 100 matches and position is corresponding.One end of recess 210 is fixed with main body 311 Connection, the other end are vertically and fixedly provided with limiting plate 220.In locking, latch hook 100 catches on recess 210, in the limitation of limiting plate 220 Under, latch hook 100 is without departing from recess 210.

As shown in Figure 1 and Figure 5, the side of second housing 420 is fixed with latch hook 100, the downside of latch hook 100 offer opening to Under breach 110, when breach 110 is caught in the recess 210 of locking plate 200, the first shell 410 is locked in second housing 420 Together；When breach 110 leaves the recess 210 of locking plate 200, you can unblock.

As shown in fig. 6, during lock-out state, gangbar 312 is in the short end 321a of eccentric orfice 321, and lock core 330 is in first The lower end in hole 313, the breach 110 of latch hook 100 are caught in the recess 210 of locking plate 200；As shown in fig. 7, during unblock, lock core is rotated 330, lock core 330 drives locking plate 320 to be rotated with fixing nut 332 for axle, when gangbar 312 slides into the long end of eccentric orfice 321 During 321b, lock core 330 is in the upper end in the first hole 313, and gangbar 312 drives main body 311 to move down, and drive is fixed on main body Locking plate 200 on 311 also moves down, make latch hook 100 breach 110 depart from locking plate 200 recess 210, and not by The stop of limiting plate 220, you can unblock.

Embodiment 2

Embodiment 2 is roughly the same with embodiment 1, and difference is, drive mechanism 300 moves up and down with moveable lock hook 100, Rather than locking plate 200.

Specifically, latch hook 100 is fixed in the main body 311 of locking bar 310, and locking plate 200 is fixed on the door-plate of opposite side Or on shell.

Above content is only preferred embodiment of the present utility model, for one of ordinary skill in the art, according to this reality , in specific embodiments and applications can be so that many changes may be made, as long as these changes are without departing from this with new thought The design of utility model, belongs to the scope of protection of the utility model.
