Abstract
The utility model discloses a gear mechanism type centrifugal door lock which comprises a body and a door cover, wherein the top of the body is provided with a latch, and the bottom of the door cover is provided with a dead bolt. The latch arranged in the body can automatically insert in an automatic locking mechanism in the dead bolt. The automatic locking mechanism comprises a toothed disc I connected to the pushing end of the latch, and the toothed disc I engages with the other toothed disc I in the automatic locking mechanism. The body is also provided with a motor, of which the output shaft is connected with a speed regulator with a rotary disc. The rotary disc rotates when driven by the motor and the speed regulator, and a connecting rod is hinged between the rotary disc and the toothed disc II. The toothed disc II rotates when driven by the rotary disc and the connecting rod, and the latches on the toothed disc I and the toothed disc II are pushed into the dead bolt to lock the body and the door cover. The gear mechanism type centrifugal door lock solves the technical problem that a conventional door lock control mechanism has to be installed beside a machine. The gear mechanism type centrifugal door lock is flexible for installation and high in use safety coefficient.

Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples are only for the utility model is described but not for limiting scope of the present utility model.
Referring to Fig. 1, a kind of gear mechanism formula door lock of centrifuge that the utility model provides, comprise body 1 and door closure 2, described body 1 top is provided with latch 3, door closure bottom is provided with dead bolt 4, by latch 3 is inserted in dead bolt 4, realize closing of body 1 and door closure 2, in order to solve the technical problem described in background technology, the technical solution of the utility model is, provide a kind of and can automatically latch 3 be inserted into the automatic locking mechanism 5 in dead bolt 4, described automatic locking mechanism 5 comprises the toothed disc I 51 being connected on latch 3 promote-sides, described toothed disc I 51 is meshed with another toothed disc II 52 in automatic locking mechanism 5, in described body 1, be also provided with motor 6, on the output shaft of described motor 6, be connected with speed regulator 7, described speed regulator 7 is provided with rotating disk 8, described rotating disk 8 is driven and is realized rotation by motor 6 and speed regulator 7, between described rotating disk 8 and said gear dish II 52, be hinged with connecting rod 9, toothed disc II 52 realizes rotation by the drive of rotating disk 8 and connecting rod 9, and then by toothed disc I 51, latch 3 in toothed disc II 52 is all pushed in dead bolt 4, realize closing of body 1 and door closure 2.
As centrifugal accident power-off midway, rotating disk 8 keeps static, guarantees that door closure 2 still maintains the lock status, open door closure 2 as need, the poke hole 10 that can utilize specific purpose tool to aim at rotating disk 8 centers rotates, and pulls connecting rod 9 that toothed disc II 52 is rotated counterclockwise, make latch 3 depart from dead bolt, door closure 2 just can be opened.After normal centrifugal end, motor 6 drives rotating disk 8 to rotate, and makes latch 3 depart from dead bolt 4, and door closure 2 automatically springs open under tension force effect.
Connecting rod 9 can regulate arbitrarily length by random device height, and the rotation control sections such as motor 6 and speed regulator 7 can be below toothed disc II 52 be placed arbitrarily within the scope of 180 degree and do not affected door lock control effect.
Embodiment 1
In order to improve the degree of control to automatic locking mechanism 5, avoid occurring that latch 3 inserted deeply or inserted not enough phenomenon, can magnet ring 11 be installed at the circumference place of described toothed disc I 51 and/or toothed disc II 52, close on described toothed disc I 51 and/or toothed disc II 52 places the position sensor 12 that can respond to mutually with magnet ring 11 is installed; In described dead bolt 4 bottoms, magnetic post 13 is installed, the dead bolt sensor 14 relative with magnetic post 13 is installed in body 1, described position sensor 12, dead bolt sensor 14 all join with the control system signal of centrifuge.
Press close to when magnetic post 13 and dead bolt sensor 14, under magnetic fields, dead bolt sensor 14 is exported from high level and is become low level.In the time that machine detects that dead bolt sensor 14 all becomes low level, illustrate that now door closure shuts completely.
