Abstract
The utility model relates to an electric controlled door lock device of a centrifugal machine. During a MCA test process, a lock of the centrifugal machine is required to have enough locking force to a cover of the centrifugal machine so as to stop broken fragments, but the original electric control door lock which adopts an automobile trunk lock and electromagnetic control unlocking is thin in body and can not meet requirements of MCA tests and is high in unlocking noise when unlocked by means of electromagnetic control. The electric controlled door lock device of a centrifugal machine consists of a lock support, a lock wheel, a catch pawl, a duplex torsional spring, a pin, a micro switch, a connecting rod, a micro motor, a speed reducing box, an eccentric wheel, a position sensor, and has the advantages of fine locking effect, simple structure, convenient installation and use, and stable, labor-saving and non-noise operation.
Description
Technical field
The utility model belongs to the electric control door lock technical field, is specifically related to a kind of centrifuge electric control door lock device.
Background technology
According to GB4793.7 (idt IEC 61010-2-020) " security laboratory of measurement, control and laboratory electrical installation with the specific (special) requirements regulation of centrifuge ": in the centrifuge MCA test process, require the centrifuge door lock that cover is had enough coupling mechanism forces, the centrifuge shell can suppress the damaged fragment that produces.Original electric control door lock adopts the automobile trunk lock to unblank with magnet control, and lock body is thin, can not satisfy the MCA test request.Magnet control is unblanked, and the noise of unblanking is big.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, and provide a kind of cover is had enough coupling mechanism forces, and is simple in structure, easy for installation, durable in use, can satisfy the centrifuge electric control door lock device of centrifuge MCA test request.This electric control door lock compares with former electric control door lock, and cover is had enough coupling mechanism forces, can satisfy centrifuge MCA test request.Electric control door lock promotes connecting rod by micro machine, reduction box, eccentric wheel and unblanks, and operates steadily, and is laborsaving, noiseless.Unlocking apparatus is to separate with door lock, fastens rope on connecting rod, can realize manually unblanking.
The utility model is achieved in that it comprises door lock assembly structure and electrical control two parts, and the door lock assembly structure division comprises door lock and unlocking apparatus.
This door lock assembly structure division: form by lock support, lock wheel, lock ratchet, duplex torsion spring, lock shaft, two connecting rods.Two lock shafts are installed on the lock support, and lock is taken turns, locks ratchet, is installed on two lock shafts respectively, and duplex torsion spring two ends are separately fixed on lock wheel and the lock ratchet, and microswitch is installed on the lock support, places to lock under the ratchet.Connecting rod is installed on the lock support, is connected with the lock ratchet with pin.
The electric control system of this door lock: comprise master board, microswitch (6), position sensor (11).Its unlocking apparatus is made up of micromachine, reduction box, eccentric wheel, position sensor.Its micromachine is installed on the reduction box, and eccentric wheel is installed on the micromachine, and position sensor is installed in eccentric wheel the place ahead.
Description of drawings:

Fig. 2 is the utility model centrifuge electric control door lock backsight structural representation
Figure grade: 1 lock support, 2 lock wheels, 3 lock ratchets, 4 duplex torsion springs, 5 bearing pins, 6 microswitches, 7 connecting rods, 8 micromachines, 9 reduction boxes, 10 eccentric wheels, 11 position sensors.
The specific embodiment:
Centrifuge electric control door lock device of the present utility model, it comprises mechanical door lock and electrical control two parts, specifically by lock support (1), lock wheel (2), lock ratchet (3), duplex torsion spring (4), bearing pin (5), microswitch (6), connecting rod (7), micromachine (8), reduction box (9), eccentric wheel (10), position sensor (11) constitutes this device.
This door latch structure part is made up of lock support (1), lock wheel (2), lock ratchet (3), duplex torsion spring (4), lock shaft (5), two connecting rods (7).Two lock shafts (5) are installed on the lock support, lock is taken turns (2), lock ratchet (3), is installed on two lock shafts (5) respectively, duplex torsion spring (4) two ends are separately fixed on lock wheel (2) and the lock ratchet (3), and microswitch (6) is installed on the lock support (1), place under the lock ratchet (3).Connecting rod (7) is installed on the lock support (1), is connected with lock ratchet (3) with pin.
The automatically controlled part of this door lock comprises master board, microswitch (6), position sensor (11).Its unlocking apparatus is made up of micromachine (8), reduction box (9), eccentric wheel (10), position sensor (11).Micromachine (8) is installed on the reduction box (9), and eccentric wheel (10) is installed on the micromachine (8), and position sensor (11) is installed in eccentric wheel (10) the place ahead.
The electric control door lock operation principle: (one), when cover is closed, the latch hook on the cover down promotes lock wheel (2), and lock wheel (2) turns clockwise around a bearing pin.Under duplex torsion spring (4) effect, lock ratchet (3) rotates around another lock shaft (5), and draws close to lock wheel (2).In the closed position when door lock, lock ratchet (3) just in time is stuck in lock wheel (2) indent circular arc position.Stop the reverse rotation of lock wheel.At this moment, microswitch is in normally off, and the eccentric wheel on the unlocking apparatus (10) also is in minimum position.Master board is handled by signal, shows the door lock closed condition.(Fig. 1).(2), when cover is opened, master board instruction micro machine (8) rotation drives eccentric wheel (10) by reduction box (9) and turns clockwise, and promotes connecting rod (7), connecting rod (7) drive lock ratchet (3) around lock shaft (5) to the direction rotation of leaving lock wheel (2).Under duplex torsion spring (4) effect, lock wheel (2) is rotated counterclockwise door-lock opening around a bearing pin.At this moment, microswitch is in normally open, and the eccentric wheel on the unlocking apparatus (10) detects by position sensor (11), stops at minimum position again.Master board is handled by signal, shows the door lock opening.
