Description
Technical field:
The utility model relates to a kind of lock, particularly relates to a kind of electromagnetic lock that is used on door or the cabinet.
Background technology:
In people's inhabitation and workplace, the electromagnetic lock that is provided with on various safety doors and the fire exit door under emergency, should make it be in " outage is often opened " duty, with evacuation and the escape that makes things convenient for the crowd.And for confidential occasions such as banks, then need to be in " it is normally closed to cut off the power supply " duty, when accident took place, all passage was closed, to guarantee safety.Existing electromagnetic lock (referring to Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4) is made of solenoid component 1, lockhole column 2, lock body 3, movable supporting frame 4, microswitch 5 and snap close 6, Fig. 2 is the schematic diagram that snap close 6 is in opening, and Fig. 3 is the schematic diagram of closure state.Lock body 3 is a groove structure, is provided with two boss (32,33) in the described groove 31, respectively is provided with a pin-and-hole (34,35) on each boss; Described snap close 6 is the center with pivot 7, flexibly connects by its articulated jib 61 and pivot 7, and wherein the articulated jib 61 of a side extends outward a boss 62, and boss 62 is provided with pin-and-hole 63, and pin-and-hole 63 and pin-and-hole (34,35) concentric; The boss 62 of articulated jib 61 places between two boss (32,33); Solenoid component 1 places in the groove 31 of lock body 3, and is positioned at one side of lock body 3, its iron core and lockhole column 2 concentrics and hold mutually; Described lockhole column 2 is divided into three sections (21,22,23), and in the pin-and-hole of packing into successively (34,63,35), each section of lockhole column 2 (21,22,23) length thickness with boss (32,62,33) respectively is identical.Described movable supporting frame 4 is contained in the side in the lock body 3, and the one end leans on mutually with the outside of solenoid component 1, and the other end is positioned at the back of lockhole column 2, and is affixed with microswitch 5.Be equipped with four screws of two rows on solenoid component 1, movable supporting frame 4 and the lock body 3, and three's screw cooperatively interacts, wherein two screws at the diagonal angle on the lock body 3 are Chang Yuan hole 36 and 37.When needs are regulated duty, as long as unclamp the screws in the Chang Yuan hole 36 and 37 on the lock body 3, can regulate solenoid component 1 and the position of microswitch 5 in lock body 3 by pulling movable supporting frame 4 and reach adjustings and " cut off the power supply and often open " and the purpose of " it is normally closed to cut off the power supply " two kinds of duties.Other two diagonal angle screws on the lock body 3 play reinforcement effect, are respectively applied for two kinds of duties.When electromagnetic lock was in " outage is often opened " duty, lockhole column 22 was concordant with the two ends of the boss 62 of articulated jib 61, and snap close 6 can freely rotate.Under this dead electricity opening, have only after solenoid component 1 energising, iron core impels lockhole column (21,22,23) to move, the both ends of the surface of the boss 62 of the both ends of the surface of lockhole column 22 and articulated jib 61 dislocation at this moment, snap close 6 is locked, and door can not be opened.When needs from " outage often open " when duty changes " it is normally closed to cut off the power supply " duty over to, unclamp the screw on the lock body 3, regulate the position of movable supporting frame 4, solenoid component 1 and microswitch 5 are moved together, lockhole column 2 is produced thereupon to be moved, at this moment the both ends of the surface of the boss 62 of the both ends of the surface of lockhole column 22 and articulated jib 61 dislocation, snap close 6 can not freely rotate, and is in locking state.When electromagnetic lock is in " it is normally closed to cut off the power supply " duty, have only after solenoid component 1 energising, iron core impels lockhole column (21,22,23) to move, and script moves to concordant with the lockhole column 22 of the both ends of the surface dislocation of the boss 62 of articulated jib 61, snap close 6 is free to rotate, and door can be opened.Because the effect of the torsion spring on the pivot 7, snap close 6 can restore and discharge conversion between two kinds of positions.The conversion of two kinds of duties, by regulating movable supporting frame 4 solenoid component 1 and microswitch 5 are realized the shift position simultaneously, the advantage of this structure is solenoid component 1 and the same moved further of microswitch 5 energy, shortcoming is that the screw required precision of solenoid component 1, movable supporting frame 4 and lock body 3 is higher, difficulty of processing is big, cause error easily, cause whole group lock malfunctioning during adjustment state easily, be not suitable for large batch of production.
Summary of the invention:
The purpose of this utility model is big in order to overcome the screw precision height, the difficulty of processing that have the electromagnetic lock requirement now, and the inconvenient shortcoming of conversion between Chang Kai and the normally closed two states, provide a kind of simple in structure, easy to process, between Chang Kai and normally closed two states, change electromagnetic lock easily.
The technical solution of the utility model is achieved in that a kind of electromagnetic lock of improvement, by solenoid component 1, lockhole column 2, microswitch 5, snap close 6 and lock body 8 constitute, it is characterized in that: lock body 8 is by fixedly lock body 81 and adjustable lock body 82 constitute, described fixedly lock body 81 is made of side plate and base plate two parts, both become " L " shape structure, described adjustable lock body 82 also is made of base plate and side plate two parts, wherein be spill in the middle of the base plate, make this base plate be divided into noseplate and back base plate two parts, and the base plate of adjustable lock body 82 is stacked on the base plate of fixing lock body 81, and two lock bodies are combined into " ∪ " type structure; The noseplate of described adjustable lock body 82 is provided with the hole that is connected with stationary solenoids assembly 1, and back base plate is provided with regulates screw 822, and this round screw 811 of regulating on the base plate of screw 822 and fixing lock body 81 cooperates; Described lockhole column 2 is a cuboid, and the centre is concave structure, and this concave portions cooperates with the boss 62 of articulated jib 61; Described lockhole column 2 is fixed in the front end of solenoid component 1 by the carriage activity, and holds with the push rod of solenoid component 1; Described microswitch 5 is fixed on the adjustable lock body 82 by carriage 825, and holds with lockhole column 2.
The carriage of described support lockhole column 2 can be fixed on the adjustable lock body 82.
The carriage of described support lockhole column 2 can be fixed on fixedly on the lock body 81.
The carriage of described support lockhole column 2 also can partly combine by two, and some is fixed on fixedly on the lock body 81, and another partly is fixed on the adjustable lock body 82.
Be provided with two grooves arranged side by side below the base plate of described adjustable lock body 82, promptly often open groove 823 and normally closed groove 824, the relative position of two grooves is corresponding with the width of regulating screw 822, and these two grooves all can cooperate with the trip 812 above the base plate of fixing lock body 81.
The utility model has the advantages that, reduced the conversion formality, conversion is simple; The microswitch position produces skew when avoiding changing; Accurate positioning, processing request is simple; Product with stable quality is suitable for producing in batches.
