Abstract
The utility model relates to a pressure steam sterilizer door lock which belongs to the sterilizer fittings. A pressing sheet is fixed on a lock pin, an electromagnetic solenoid corresponding to the pressing sheet is arranged, and a spring is arranged between the pressing sheet and the electromagnetic solenoid; a position sensor corresponding to the pressing sheet is arranged, a pressure sensor is arranged on a body of a sterilizer, and the position sensor and the pressure sensor are respectively connected with an automatic control microprocessor through signal lines. The lock with a simple structure is safer and more reliable than a mechanical lock. The lock which has good durability, a long service life, and convenient manufacturing, assembly and use can realize automatic detection and control. The lock which is easy to realize the automatic opening and closing of a seal door due to good application performance can meet the requirements on the safety interlocking of the pressure steam sterilizer seal door.
Description
Technical field
The utility model relates to a kind of pressure steam sterilizer door lock, belongs to the sterilizer accessory.
Background technology
The mechanical door lock of traditional pressure steam sterilizer, the characteristic of general using silica gel material compressive deformation are realized the flexible of lock pin, and three shortcomings are arranged: the one, and silica gel material use back is aging easily breaks poor durability; The 2nd, the lock pin position is not detected, and has risk not in place; The 3rd, door lock can not be realized automatic control, can not open as required or close.Therefore, application performance is not ideal enough.
The utility model content
The purpose of this utility model is to provide a kind of pressure steam sterilizer door lock, and is simple in structure, the reliability height, and durability is good, long service life, and can realize detecting automatically and control, application performance is good.
Pressure steam sterilizer door lock described in the utility model has lock pin, is fixed with compressing tablet on its lock pin, and corresponding compressing tablet is provided with o, is provided with spring between compressing tablet and the o.
O can produce electromagnetic attraction after energising, can make compressing tablet and lock pin attract to move, thereby can control the moving state of lock pin by the switching electricity situation of control o.Lock pin is withdrawn under the magneticaction that o produces, and makes door lock be in opening; Under the elastic force effect of spring, stretch out, make door lock be in closed condition.
Can establish position sensor by corresponding compressing tablet, on the sterilizer main body, set up pressure sensor, position sensor is connected control microprocessor automatically by holding wire respectively with pressure sensor, thereby realize control automatically.
Microprocessor is an arithmetic and control unit, is responsible for gathering pressure and position signalling, judges the condition that door lock is opened or closed, and controls the power on/off of o, and the location status information of door lock is provided.
Lock pin is an action actuating mechanism, can withdraw under the magneticaction that o produces, and stretches out under the elastic force effect of spring, finishes the action of release and lock door handle.
The action of lock pin is carried out according to the setting command of microprocessor, and microprocessor can be known the lock pin physical location by position sensor, confirms that lock pin is by its command action.Microprocessor can be known the sterilizer external and internal pressure by pressure sensor, and the assurance lock pin is opened in safe range.
Position sensor, pressure sensor and control microprocessor automatically are conventional automatic control device or device, directly use to get final product.
Pressure sensor directly is connected on the sterilizer main body by annulus line, detects the pressure changing in the main body in real time, pressure measurement scope-100kPa～+ 300kPa.Pressure sensor detects the sterilizer external and internal pressure, and microprocessor system is judged pressure reduction in safe range, to o connection DC current, produces the withdrawal of magnetic force pulling lock pin, makes the sterilizer hermatic door be in released state; When the sterilizer inside and outside differential pressure exceeds safe range, the o dead electricity, lock pin stretches out under the effect of spring, blocks the sterilizer door handle, and the sterilizer hermatic door can't be opened.
Position sensor is installed in the lock pin next door, and when lock pin was withdrawn, compressing tablet moved with lock pin and touches position sensor, position sensor output start signal; When lock pin stretches out, compressing tablet off-position sensor, position sensor output shutdown signal.Position sensor is used for detecting the lock pin position, and feeds back to microprocessing systems, confirms that the lock pin action puts in place.So design, even when disconnection fault appears in position sensor, microprocessor can think that also door lock is in opening, guarantees the pressure steam sterilizer safety operation.
The utility model pressure steam sterilizer door lock, simple in structure, more safer, more reliable than mechanical lock, durability is good, and long service life makes, installs, uses easy to operate, and can realize detecting automatically and control, application performance is good, is easy to realize hermatic door unlatching, the automatic operation of closing, and can satisfy the requirement of pressure steam sterilizer hermatic door safety interlocking well.
Description of drawings
Fig. 1, the structural representation when the utility model door lock is in opening.
Fig. 2, the structural representation when the utility model door lock is in closed condition.
Among the figure: 1, lock pin 2, spring 3, o 4, compressing tablet 5, position sensor 6, door handle.
The specific embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in Figure 1 and Figure 2, pressure steam sterilizer door lock described in the utility model is fixed with compressing tablet 4 on the lock pin 1, and corresponding compressing tablet 4 is provided with o 3, is provided with spring 2 between compressing tablet 4 and the o 3.
Corresponding compressing tablet 4 is provided with position sensor 5, sets up pressure sensor on the sterilizer main body, and position sensor 5 can be connected control microprocessor automatically by holding wire respectively with pressure sensor.
Lock pin 1 can be withdrawn under the magneticaction that o 3 produces, and stretches out under the elastic force effect of spring 2, finishes the action of release and lock door handle, realizes the opening and closing of hermatic door.
Can pass through rigging position sensor, pressure sensor and microprocessor, realize control automatically.
Claims (2)
1, a kind of pressure steam sterilizer door lock has lock pin, it is characterized in that being fixed with on the lock pin compressing tablet, and corresponding compressing tablet is provided with o, is provided with spring between compressing tablet and the o.
