Embodiment
In conjunction with above accompanying drawing the utility model is described in detail, the used self-locking of the utility model from releasing mechanism is, guide sleeve 1 is fixed in the low-voltage electrical apparatus housing, the cylinder of guide rod 3 bottoms is evenly equipped with that 8 keys are sliding respectively to fit over that 4 deep trouths 5 and 4 shallow slots 6 of stagger arrangement are slippery mutually in the guiding trepanning, the termination of 8 keys of guide rod is a wedge, the angle on two inclined-planes of wedge is 90 degree (referring to Fig. 4) and the angled end-face relative (referring to Fig. 6) of 4 keys of guiding on the locking lever 2, and the gradient on this inclined-plane is 45 to spend.The diameter of 4 deep trouths in 4 keys on the guide rod and the guiding trepanning is identical, and the diameter of other 4 keys is identical with the diameter of 4 shallow slots of guiding in the trepanning, the diameter of 4 keys of guiding on the locking lever is identical with deep trouth diameter in the trepanning that leads, thereby the key of guiding locking lever can not enter in the shallow slot of guiding in the trepanning, the stepped cylinder of guiding locking lever upper end and the center hole of guide rod are rotatably assorted, and are provided with spring 4 between guiding locking lever and the housing.
The said low-voltage electrical apparatus of the utility model is meant solenoid valve, contactor (or relay) and tractive magnet, its common ground is to utilize the electromagnet energising to produce magnetic force promotion armature to move a distance, realize the conversion of switching state, when needs keep this state, will continue to power to electromagnet, above-mentioned low-voltage electrical apparatus is provided with self-locking from releasing mechanism, just can realize not keeping the on-off state to the electromagnet continued power, thereby have the function of economize on electricity.
Be provided with self-locking from releasing the solenoid valve (referring to Fig. 8) of mechanism, guide sleeve 1 is fixed in the hole of the piston 10 in the valve casing 9, and the termination of guiding locking lever 2 contacts with piston 10, and the termination of guide rod 3 and armature 8 contact, and spring 4 places between piston and the valve casing.There is self-locking to be from the working principle of releasing the solenoid valve of mechanism, Fig. 8 is the solenoid valve on-state, when needs turn-off solenoid valve, switch on to electromagnet, armature promotes guide rod and piston moves down, this moment, spring 4 was compressed, when the key of guiding locking lever breaks away from the shallow slot of guide sleeve 1, rotate an angle around the center, this moment the electromagnet dead electricity, spring 4 is rotated further the guiding locking lever, its termination enters in the guide sleeve deep trouth 5, this moment, piston was closed the passage of valve body, realized throttle down and kept this state, and do not need to power to electromagnet coil for a long time.When needs are opened solenoid valve, switch on to electromagnet, armature moves down the promotion guide rod and piston moves down, guide rod key in the guide sleeve deep trouth makes guiding locking lever disengaging deep trouth port and rotates an angle and enters in the shallow slot port at this moment, electromagnet outage this moment realizes the connection of solenoid valve path and keeps this state.
Be provided with self-locking from releasing the contactor (referring to Fig. 9) of mechanism, guide sleeve 1 is fixed on the housing between armature 13 and the contactor shell 11, the upper end of guiding locking lever 2 contacts with armature, is provided with spring 4 between the lower end of guide rod 3 and the housing, is provided with spring 15 between movable contact support 14 and housing.Fig. 9 is the contactor closed state, and the port that 4 keys of locking lever that lead this moment are in guide sleeve shallow slot 6 is locked.When contactor need disconnect, make electromagnet 12 energisings, the locking lever disengaging moves on the armature 13 and leads, the key of the guide rod under spring 4 effects in 4 shallow slots 6 of guide sleeve makes the rotation of guiding locking lever relative with deep trouth mouth 5, this moment, the electromagnet energising finished, because the elastic force of spring 15 is greater than the elastic force of spring 4, so the key of guiding locking lever enters in the deep trouth of guide sleeve, the movable contact 16 of contactor breaks away from fixed contact 17, and contactor disconnects.
Be provided with self-locking from releasing the tractive magnet of mechanism, the lower end of armature 20 is provided with a hole, two bar holes of the two side in hole and electromagnet housing 18 are slippery, guide sleeve 1 is fixed on the lower end surface of electromagnet housing, spring 4 places between guide rod 3 and the electromagnet housing 18, the other end relative with the armature end face (referring to Figure 10) of guiding locking lever 2.The working principle of this tractive magnet is, when tractive magnet draws, the electromagnet energising, armature 20 moves down under magnetic force, and the guide rod key moves down the guiding locking lever, changes the port that an angle enters shallow slot 6 when the key of guiding locking lever shifts out the port of guide sleeve deep trouth 5, outage this moment, armature loses magnetic force, and the guiding locking lever is locked, and armature can not reset.If when tractive magnet does not need traction (resetting), electromagnet is switched on once more, can reset, remove traction state.
