The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
The schematic diagram of the utility model air-valve magnetic lock comprises lock body shell 4, lock body inner core 10 as shown in Figure 1, connects base 11 and key 2.The schematic diagram of lock body shell as shown in Figures 2 and 3, described lock body shell 4 inside are disposed with annular groove 5, annular boss 6, lead-over groove 7 and annular ball grooves 8 from the top down, are fixed with slide block 16 on the annular boss on the lock body shell.The schematic diagram of lock body inner core such as Fig. 4, Fig. 5 and shown in Figure 6 are provided with chute 28 with slide block 16 corresponding positions on lock body inner core 10.Described lock body inner core places in the lock body shell, is provided with two back-moving springs 3 between lock body inner core upper end and lock body shell, and back-moving spring is evenly arranged.The lock body inner core sidewall of back-moving spring lower end is provided with two pressure spring slots, is provided with stage clip 14 in each pressure spring slot, and stage clip 14 is connected with magnetic force pin 13.On the lock body inner core, be provided with two position-limitting pin grooves, in each position-limitting pin groove, be provided with stage clip 17 and the position-limitting pin 12 that is connected with stage clip with the corresponding position of annular groove.Wherein, position-limitting pin and magnetic force pin are evenly arranged.Be provided with lock body shell limiting stand 18 in lock body inner core lower end.The schematic diagram of connection base as shown in Figure 7, described connection base 11 places lock body inner core 10, be provided with volume damper adjusting rod hole 19 in connection base inside, be provided with connection platform 20 in connection base lower end, connect the base circumference and be provided with lock body inner core limiting stand 21, be provided with a plurality of ball holes relative with lock body shell ball grooves in lock body inner core bottom, be provided with annular ball runway 22 with the base that is connected of ball hole relevant position, each ball 9 places the ball hole of lock body inner core, and is positioned at the annular ball grooves and the annular ball runway that is connected base of lock body shell.The schematic diagram of key such as Fig. 8 and shown in Figure 9, described key comprises key body 26, described key body 26 inside are provided with and the corresponding groove 27 of lock body shell, are embedded with the magnet piece 1 identical with magnetic force pin magnetic in key body inside with the corresponding position of magnetic force pin.
Unblank for convenience, key body is provided with the mark 23 of unblanking.The lock body shell mark 23 corresponding marks of unblanking that are provided with and unblank.For weight reduction, on key body, along the circumferential direction be provided with a plurality of fabrication holes 24.Be provided with air quantity adjustment hole 25 at the center of key body, after the air-valve magnetic lock is opened, this adjustment hole aligned on the adjusting rod that is inserted in valve body, can regulate valve body.
During use, the connection platform 20 that connects on the base 11 is riveted on the volume damper valve body cover plate, and the adjusting rod 15 of volume damper penetrates in the adjusting rod hole 19 that connects on the base.Air adjusting valve body case 4 is sleeved on the lock body inner core 10, and the slide block 16 of lock body shell places in the chute 28 on the lock body inner core, lock body shell 4 is installed in lock body inner core 10 assemblys be connected on the base 11.The position-limitting pin 12 of lock body inner core places annular groove 5 bottoms of lock body shell at this moment, and undertaken spacing by the effect of back-moving spring, and magnetic force pin 13 places in the lock body shell annular boss 6, ball 9 places in the annular ball grooves 8 of lock body outer casing underpart, this moment, the air-valve magnetic lock was in opening, can use adjustment means by the air quantity adjustment hole on the key body air-conditioning system air quantity to be regulated.
Push lock body shell 4 downwards, the lock body shell moves downward, make the back-moving spring 3 in the lock body inner core 10 produce compression simultaneously, this moment, the magnetic force pin 13 of lock body inner core ejected the magnetic force pin to the annular groove 5 of lock body shell under the effect of the active force of connected stage clip 14, meanwhile, ball 9 is subjected to the excessively extruding of groove 7 of lock body shell annular, makes ball in the annular ball runway 22 that connects base, and this moment, the air-valve magnetic lock was in locking states.
In the time of need carrying out the air quantity adjusting, pass through key unlocking.Make two blocks of magnet 1 of key align the magnetic force pin 13 of lock body inner core by the mark of unblanking, with key cover on the lock body shell.With key to pressing down the lock body shell, the magnetic force pin is disappeared because of the vertical strength of the tension force generation of back-moving spring, simultaneously, because of the magnet of key institute carry magnet 1 and magnetic force pin 13 is homopolarity, under the active force of magnetic homopolar-repulsion, make 13 pairs of connected stage clips 14 of magnetic force pin produce pressure, magnetic force pin 13 is concealed in connected pressure spring slot.Unclamp the magnetic force key of exerting pressure downwards, this moment, the lock body shell was under the effect of lock body inner core back-moving spring 3, upwards produce displacement fast, the magnetic force pin is placed in the lock body shell annular boss 6, position-limitting pin 12 places the lower edge of lock body shell upper annular groove 5,9 on ball places in the annular ball grooves 8 of lock body outer casing underpart, lost extruding force to the excessive groove of lock body shell annular, ball is in free state, this moment, the air-valve magnetic lock was in opening, it can be taken down by connecting on the base, by the instrument rotary regulating lever, thus the opening angle of adjusting air-valve.
Although relate to a kind of air-valve magnetic lock and carried out special description disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
