Embodiment
Shown in figure 1 ~ Fig. 3, disclose the structure chart of the energy storage release according to an embodiment of the present utility model.Wherein Fig. 1 is the structure that this energy storage release is in energy storage state, and Fig. 2 is that this energy storage release is in the structure releasing energy state, and Fig. 3 discloses this energy storage release from another angle.
As shown in the figure, this energy storage release comprises: support, snap close 102, trip shaft 101, first spring 103 and the second spring 105.Snap close 102 is rack-mount, snap close is provided with the second spring 105.Trip shaft 101 is rack-mount and be connected with the first spring 103.At energy storage position, snap close 102 is fixed on primary importance by the second spring 105, and snap close 102 compresses the first spring 103, and trip shaft 101 is in punctured position.Releasing can position, wink motor magnet snap close 102 force is overcome to the spring force of the second spring 105, snap close 102 is in the second place, the first spring 103 release can, release lever 101 ejects.The length of the force arm of snap close 102 is 2 ~ 3 times of the length of the dropout arm of force, therefore the power that provides of motor magnet can be less wink, the power that wink motor magnet applies can be amplified by the structure of snap close 102, be amplified to the degree being enough to the spring force overcoming the second spring 105.The spring force of the first spring 103 can be 5 ~ 10 times of the spring force of the second spring 105.The first spring 103 can be discharged after overcoming the spring force of the second spring 105, then rely on the spring force of the first spring 103 to drive trip shaft 101.After being amplified by what, originally less wink the electromagnetic force of motor magnet be amplified to the degree that stable tripping force is enough provided.
Continue with reference to shown in accompanying drawing, support comprises two end plates and two blocks of side plates.Two end plates is respectively the first end plate 161 and the second end plate 162, two blocks of side plates are 163.Snap close 102 is erected on the first end plate 161.The first end of trip shaft 101 is arranged on the first end plate 161, and the second end of trip shaft 101 extends to outside the second end 162 plate.Two blocks of side plates 163 have axis hole 164 in the position near the first end plate 161.
The middle part of snap close 102 has rotating shaft 121, and rotating shaft 121 is arranged in axis hole 164.Snap close 102 extends from middle part to both sides.The first end 122 of snap close 102 extends to outside the first end plate 161, and the first end 122 of wink motor magnet to snap close exerts a force, in the illustrated embodiment in which, wink motor magnet to thread off first end on stress point 123 exert a force.Second end 124 of snap close is positioned at support, and the second end 124 of snap close is formed with step surface 125.Shown in figure 2, snap close is formed with passage along its length, and passage passes for trip shaft and the first spring.Shown in figure 4, the distance of stress point 123 to the rotating shaft 121 on the first end of snap close is force arm, and the distance of step surface 125 to the rotating shaft 121 of the second end of snap close is the dropout arm of force.The length of force arm is 2 ~ 3 times of the length of the dropout arm of force, so, wink the power that applies to stress point 123 of motor magnet be exaggerated 2 ~ 3 times at the second end.Shown in figure 3, the second spring 105 is torsion spring, and the second spring 105 is sleeved in rotating shaft 121, and two reverse arms of torsion spring are separately fixed on the inner side of the first end plate 161 and the bottom surface of snap close 102.
The first end of trip shaft 101 is fixed on the first end plate 161, and the middle part of trip shaft 101 has the sliding axle 104 of horizontal expansion.First spring 103 is enclosed within trip shaft 101, between the first end and sliding axle 104 of trip shaft 101.Trip shaft 101 and the first spring 103 pass snap close 102 passage along its length, to be fixed on the first end plate 161.Second end of trip shaft 101 extends to outside the second end plate through the second end plate 162.Side plate 163 has chute 165, sliding axle 104 is arranged in chute 165.
At energy storage position, snap close 102 is fixed on primary importance by the second spring 105.Now torsion spring relies on the spring force of himself snap close 102 to be remained on the position of level.Sliding axle 104 is just in time stuck on step surface 125.First spring 103 is compressed, and trip shaft 101 is in punctured position.
Releasing energy position, wink, motor magnet was to the second end force of snap close 102, and force application location is at stress point 123.Wink, the power of motor magnet made snap close 102 produce the trend rotated, and after overcoming the spring force of the second spring 105, snap close 102 rotates to the second place.In the illustrated embodiment in which, after snap close rotates, the second end moves down, and sliding axle 104 skids off from step surface 125, and the first spring 103 is released and can be promoted sliding axle 104 and slide along chute 165, and release lever 101 ejects.
Shown in figure 4, disclose the operation principle of the energy storage release according to an embodiment of the present utility model.First the utility model utilizes snap close to constitute a rotating mechanism, and with rotating shaft 121 for center of rotation, rotating shaft 121 to stress point 123 is force arm, and rotating shaft 121 to step surface 125 is the dropout arm of force.The length L1 of force arm is 2 ~ 3 times of the length L2 of the dropout arm of force.In one embodiment, the length L1 of force arm is 2 times of the length L2 of the dropout arm of force.Like this, wink, motor magnet was to the power of stress point applying 1N, in the position of step surface 125, produced the tripping force of 2N.The effect of this rotating mechanism is to carry out state control to the first spring 103, rotating mechanism comprises the second spring 105, the spring force of the second spring 105 can be arranged between 1N ~ 2N, the effect of the second spring 105 is when wink, motor magnet did not apply external force, utilize its spring force to come snap close position, position, the first spring 103 is compressed in energy storage state.After the first spring 103 is released energy, the first spring 103 utilizes the spring force of himself to drive trip shaft 101, and the spring force of the first spring 103 is tripping forces that this energy storage release real outwards exports.The spring force of the first spring 103 can be about 10N, is approximately 5 ~ 10 times of the spring force of the second spring 105.Because the first spring 103 make use of the clearance spaces of support and snap close inside, that therefore can design is larger, has larger spring force.Simultaneously, the snap close being designed to rotating mechanism make from wink motor magnet starting force and the tripping force that exports of the first spring there is different directions, in the illustrated embodiment in which, from wink, the starting force of motor magnet is vertical direction, and the tripping force that the first spring exports is horizontal direction.The direction that energy storage release can change power also provides larger convenience to the spatial design of circuit breaker.
Energy storage release of the present utility model makes full use of inner space, place two springs, and by the length designing the arm of force, less original tripping force is zoomed into larger tripping force, make less original tripping force also can form stable dropout to the circuit breaker with higher tripping force requirement.
Above-described embodiment is available to be familiar with person in the art to realize or to use of the present utility model; those skilled in the art can when not departing from utility model thought of the present utility model; various modifications or change are made to above-described embodiment; thus protection range of the present utility model not limit by above-described embodiment, and should be the maximum magnitude meeting the inventive features that claims are mentioned.
