Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
As shown in fig. 2 to 5, the spring operating mechanism of the present invention includes a frame, and an energy storage shaft, a power output shaft, and a latch are rotatably mounted on the frame, and the latch can retain the closing spring and the opening spring in an energy storage and retention state during normal use of the circuit breaker, and can also release the latch when the energy storage of the closing spring and the opening spring is released.
In order to realize the control to sincere son, the spring operating mechanism still is provided with the hasp subassembly, the hasp subassembly is including fixing base 1 in the frame, wherein base 1 includes L shape bent plate 10, L shape bent plate 10 includes the long limit and the minor face of vertical distribution (of course, in other embodiments, the contained angle that becomes between long limit and the minor face can change according to actual conditions), install two electro-magnets 2 in the outside on long limit, two electro-magnets 2 parallel arrangement, moreover, two electro-magnets 2 can act alone and do not influence each other.
Two support shafts 9 arranged in parallel are fixed on the inner side of the short side of the L-shaped bent plate 10, two latch mounting plates 5 are arranged on the two support shafts 9 at intervals along the extending direction of the support shafts 9, and two ends of a latch 3 are arranged on the latch mounting plates 5 in a reciprocating swinging mode. A striker 4 is fixed to one end of the latch 3, the striker 4 extends in the same direction as the support shaft 9, and the striker 4 has an extension portion extending to the outside of the latch 3, the extension portion corresponding to the extension rods of the two electromagnets 2, and the extension rods of the two electromagnets 2 are located on the same side of the striker 4. From the above, whichever telescopic link of two electromagnets 2 stretches out can all promote hasp 3 swing, and during the specific use, two electromagnets 2 can be used one by one, also can use simultaneously. Of course, in other embodiments, the number of the electromagnets may be arranged according to actual conditions, and in addition, the arrangement manner among the electromagnets may also be changed according to actual operating conditions, for example, the telescopic rod of one of the electromagnets is arranged corresponding to one end of the latch 3, and the telescopic rod of the other electromagnet is arranged corresponding to the other end of the latch 3.
In order to achieve the automatic reset of the latch 3, in the present embodiment, a reset rod 12 is fixedly inserted into the other end of the latch 3, the reset rod 12 is aligned with the extending direction of the striker 4, and the reset rod 12 extends to the outside of the latch mounting plate 5 to have an extending section. In this embodiment, each of the two latch mounting plates 5 has a bent portion bent outward along the extending direction of the support shaft 9, and a return tension spring 6 is elastically press-fitted between the bent portion and the extending section of the return rod 12, and the return tension spring 6 can drive the latch 3 to return to the latch stopping position (i.e., the stopping position) after the electromagnet 2 is de-energized. The reset tension spring 6 constitutes an elastic reset piece, and in other embodiments, the elastic reset piece can be a rubber belt with elasticity, and also can be a reset compression spring arranged on the other side of the reset rod.
In this embodiment, in order to meet the requirement of the reset rod 12 along with the swing stroke of the latch bolt 3 and limit the limit of the reset tension spring 6 for pulling the latch bolt 3 to reset, through holes with the diameter larger than the outer diameter of the reset rod 12 are formed in the two latch bolt mounting plates 5, the reset rod 12 penetrates out of the through holes and the reset rod 12 can swing in the through holes, and the through hole wall can limit the reset limit of the reset rod 12 to form a limit hole wall.
When the spring operating mechanism is normally used, the spring operating mechanism electrically controls opening and closing, however, when a control system of the spring operating mechanism is powered off, an opening spring and a closing spring in the spring operating mechanism still have compression energy, and a telescopic rod of the electromagnet 2 cannot stretch out and draw back under the condition that no power supply exists. In view of the above situation, in the present invention, a manual operation part is provided on the spring operating mechanism, the manual operation part comprises a manual operation plate 8 rotatably sleeved on one of the supporting shafts 9, as can be seen from fig. 3, a through slot is provided at the lower end of the manual operation plate 8, an extension section of the reset rod penetrates through the through slot, two side slot walls of the through slot can drive the extension section to swing back and forth to form a driving slot wall, and an operation handle 7 is provided on the manual operation plate 8. When the spring operating mechanism is powered off and the electromagnet cannot work normally, the operating handle 7 is manually pulled, so that the manual operating plate 8 drives the reset rod 12 to rotate, and the opening and closing operation is realized.
The using process of the invention is as follows: fig. 4 and 5 are schematic views of the spring operating mechanism in the energy storage maintaining state, in which the latch 3 is located at the position of the stopping latch 11 (i.e., the stopping position), and the latch 11 places the closing spring or the opening spring in the spring operating mechanism in the energy storage maintaining state. When the spring operating mechanism performs switching-on and switching-off operations, the electromagnet 2 is electrified, the telescopic rod of the electromagnet 2 extends out and presses the striker 4, and then the latch 3 is driven to rotate clockwise as shown in the figure 4, so that the pawl 11 is separated from being blocked by the latch 3, and then the pawl 11 is released immediately, and the switching-on or switching-off operations of the spring operating mechanism are completed. When the mechanism finishes the opening and closing operation, the electromagnet 2 loses power, the lock latch 3 resets under the action of the reset tension spring 6, and the action of the electromagnet is finished once through the stop of the through hole on the lock latch mounting plate 5.
When the spring operating mechanism can not realize electric brake opening and electric brake closing, the operating handle 7 is manually pulled to perform manual brake opening and manual brake closing, so that personal and power grid safety accidents are avoided.
In this embodiment, the electromagnet 2 is detachably connected to the long side of the L-shaped bent plate 10, and the side of the electromagnet 2, from which the telescopic rod extends and retracts, is provided with a mounting surface, and the mounting surface can be aligned with the L-shaped bent plate 10 along the telescopic direction of the electromagnet 2. Because the two can be dismantled and connected, can fill the gasket between the two and change the electro-magnet stroke clearance between telescopic link initial position and the lance, different electro-magnet stroke clearances can exert different top thrust effort to the lance. According to the invention, if the stroke clearance of the electromagnet is determined when the product leaves a factory and does not need to be adjusted in the later period, the electromagnet and the L-shaped bent plate do not need to be detachably connected, and the stroke clearance of the electromagnet can be adjusted by adjusting gaskets with different thicknesses or adjusting different numbers of gaskets during processing. In the invention, if a customer needs to adjust the stroke clearance of the electromagnet during specific use, the electromagnet and the L-shaped bent plate need to be detachably connected.
