Description

Simple door lock device of centrifugal machine

Technical Field

The utility model belongs to centrifuge, concretely relates to centrifuge's simple door lock device.

Background

With the wider application of centrifuges, the demands of customers on centrifuges are higher and higher. The centrifugal machine with small volume and high safety is very dependent on customers. The door lock is an important component of the centrifuge, and provides a safety guarantee for the centrifuge during operation. The existing door lock of the centrifugal machine has large volume and occupies a large space in the centrifugal machine. Some centrifuge door locks are very small, but have potential safety hazards, and when centrifuge rotated, the door cover also could be opened, and the machine could still normally operate, and could not provide safety guarantee. Therefore, in order to solve the above problems, it is necessary to newly design a door lock, which has a small volume, a low cost, and a high safety.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a centrifuge's simple door lock device that is small, and the security performance is high.

Realize the utility model discloses the technical scheme of purpose is:

the utility model provides a simple door lock device of centrifugal machine, including fix latch hook on the door closure, be equipped with the latch hook groove with the lock support that the latch hook corresponds, articulate on the lock support and be located the spring bolt that can elastically reset of latch hook inslot, establish motor, micro-gap switch and hall pick-up plate on the lock support, be equipped with the latch hook hole on the latch hook, be equipped with the eccentric wheel of taking the magnet steel in the pivot of motor; one end of the lock tongue is provided with a hook head with an inclined surface which is matched with a lock hook hole of the lock hook, and the other end of the lock tongue is matched with an eccentric wheel on the motor rotating shaft; the Hall detection plate is arranged at a position corresponding to the magnetic steel on the eccentric wheel, and the elastic sheet of the microswitch is positioned in the lock hook groove of the lock bracket.

And an emergency unlocking hole corresponding to the spring bolt is arranged on the lock bracket.

Has the advantages that:

1. the utility model discloses simple structure, simple to operate, small with low costs is applicable to small centrifuge.

2. The utility model discloses the assembly is simple, compares with automatic lock, need not to spend the debugging of a large amount of time, installs and can use on centrifuge.

The technical scheme of the utility model is further explained in the following with the attached drawings.

Detailed Description

Referring to fig. 1-3, the simple door lock device of a centrifuge provided by the present invention comprises a latch hook 1 fixed on a door cover, a lock bracket 2 provided with a latch hook groove 201 corresponding to the latch hook 1, a latch tongue 6 hinged on the lock bracket 2 through a shaft pin 12 and a torsion spring 13 and located in the latch hook groove 201, a motor 11 arranged on the lock bracket 2, a micro switch and a hall detection plate 10, wherein the latch hook 1 is provided with a latch hook hole 101, and a rotating shaft of the motor 11 is provided with an eccentric wheel 7 with a magnetic steel 8; one end of the lock tongue 6 is provided with a hook head 601 with an inclined surface to be matched with the lock hook hole 101 of the lock hook 1, and the other end of the lock tongue is matched with an eccentric wheel 7 on a rotating shaft of a motor 11; the Hall detection plate 10 is arranged at a position corresponding to the magnetic steel 8 on the eccentric wheel 7, the spring plate 14 of the microswitch is positioned in the lock hook groove 201 of the lock bracket 2, and the lock bracket 2 is provided with an emergency unlocking hole a corresponding to the lock tongue 6.

When the door closure is closed, the lock hook 1 is inserted into the lock hook groove 201 of the lock support 2, firstly, the lock hook 1 touches the inclined plane of the hook head 601 of the lock tongue 6, as the lock tongue 6, the lock support 2 and the shaft pin 12 form a lever, the door closure is continuously pressed lightly, the lock hook 1 slides along the inclined plane of the hook head 601 of the lock tongue 6 and jacks the lock tongue 6 open, under the torque force of the torsion spring 13, the hook head 601 of the lock tongue 6 finally hooks the lock hook hole 101 of the lock hook 1 and resets, at the moment, the lock hook 1 presses the microswitch elastic sheet 14, the microswitch closing signal gives a control program, and the fact that the door closure is locked in. When the centrifugal machine opens the door, press the centrifugal machine key that opens the door, the signal gives motor 11 this moment, motor 11 drives eccentric wheel 7 clockwise and rotates, spring bolt 6 rotates around pivot 12 under the effect of eccentric wheel 7, when latch hook 1 breaks away from the gib head 601 of spring bolt 6, latch hook 1 bounces under the effect of door closure air spring, when magnet steel 8 rotated hall 9 lower surface on eccentric wheel 7, hall pick-up plate 10 can give the signal and give the main procedure, motor 11 stall, spring bolt 6 gets back to initial position. Under the non-electricity state, the bolt 6 can be pushed open through the emergency unlocking hole a on the lock bracket 2 by a 3mm screwdriver, so that the door opening effect is achieved.

Claims (2)

1. A simple door lock device of a centrifugal machine is characterized by comprising a lock hook fixed on a door cover, a lock bracket provided with a lock hook groove corresponding to the lock hook, an elastically resettable lock tongue hinged on the lock bracket and positioned in the lock hook groove, a motor arranged on the lock bracket, a microswitch and a Hall detection plate, wherein a lock hook hole is formed in the lock hook, and an eccentric wheel with magnetic steel is arranged on a rotating shaft of the motor; one end of the lock tongue is provided with a hook head with an inclined surface which is matched with a lock hook hole of the lock hook, and the other end of the lock tongue is matched with an eccentric wheel on the motor rotating shaft; the Hall detection plate is arranged at a position corresponding to the magnetic steel on the eccentric wheel, and the elastic sheet of the microswitch is positioned in the lock hook groove of the lock bracket.
