Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Direct press type separating brake lock of the present utility model, as shown in Fig. 1-4, comprise case 1, and the lock core 2 that is positioned at case 1, one end of lock core 2 stretches out in a side of case 1, be fixed with a clamp 3 on the other end of described lock core 2, adjacent with this clamp 3 have a pressing plate 4, and this pressing plate 4 and clamp 3 are positioned at the opposite side of this case 1.
lock core 2 laterally is arranged in the lockhole of case 1, case 1 comprises around the base plate 11 of lock core 2 surroundings, two blocks of side plates 12 and top board 13, and be provided with a plurality of fixture blocks 14 on the side plate 12 on the opposite side of this case 1 and top board 13, preferably, as Fig. 1, shown in 3, the side plate of case 1 and top board respectively have a fixture block 14, the top that pressing plate 4 is corresponding and both sides respectively have a gathering sill 44 that vertically arranges, fixture block 14 is stuck in gathering sill 44, this fixture block 14 vertically is fixed on pressing plate 4 outside the opposite side of case 1, and this pressing plate 4 can move up and down outside the opposite side of case 1 along the track that these a plurality of fixture blocks 14 form.This pressing plate 4 also is provided with a crooked downward fixed block 41 towards a side of described case 1, and the two ends that the base plate 11 of case 1 is provided with groove 111, one springs 5 are butted on respectively on this fixed block 41 and detent 111, make pressing plate 4 have uptrend all the time.Nor must adopt the form of fixture block 14, track can directly be set outside the opposite side of case 1 pressing plate 4 be moved up and down along this track get final product.
As shown in Figure 4, this pressing plate 4 is provided with one " L " type groove 42, the projection 31 of this clamp 3 is located in this " L " type groove 42, clamp 3 is along with this projection 31 of rotation of lock core 2 is also made circular motion, be positioned at " L " type groove 42 of pressing plate 4 due to this projection 31, so the rotation meeting of projection 31 converts moving downward of pressing plate 4 to due to the effect of " L " type groove, make the required distance of advancing of pressing plate 4 shorten, need not along with lock core rotates, also reduce the volume of this separating brake lock.
As shown in Fig. 5,6, be the second embodiment of the present utility model, in this embodiment, different from above-mentioned the first embodiment is, this embodiment center platen 4 is provided with the groove 42 ' of other shapes, the projection 31 of clamp 3 is located in this groove 42 ', and the bottom of this groove 42 ' is " L " type, and match with the bottom of this groove 42 ' rotation that makes projection 31 that namely offsets of projection 31 converts moving downward of pressing plate 4 to.And those skilled in the art also can recognize, the base of this groove 42 ' also can be the arc that offsets with projection 31.
As shown in Figure 7, be the 3rd embodiment of the present utility model, in this embodiment, different from above-mentioned the one the second embodiment is, be not provided with groove on this embodiment center platen 4, but this pressing plate 4 is provided with the raised line 42 of an arc towards the face of clamp 3 ", the raised line 42 of this arc " match with projection 31 on clamp 3, when projection 31 rotated along with clamp 3, projection 31 was just along the raised line 42 of this arc " this pressing plate 4 of motion driving moves downward.
And those skilled in the art also can recognize, also not necessarily to use groove in above-mentioned three embodiment or the setting of raised line, also can adopt other forms of setting, groove such as arc, perhaps raised line of " L " type etc., and this projection also not necessarily is located at the periphery of clamp as shown in Fig. 1-7, also can be located at the clamp inboard, as long as can make circular motion along with the rotation of clamp.Namely as long as this clamp 3 is provided with an actuator, this pressing plate 4 is provided with one and is subjected to actuator, gets final product thereby convert the rotational motion of this clamp 3 to pressing plate 4 move up and down.
this direct press type separating brake lock, by the actuator that is subjected on the actuator on clamp and pressing plate, convert clamp to pressing plate move up and down along with the rotation of lock core, therefore the rotational motion of lock core converts moving up and down of pressing plate to, and then the clamping block below pressing plate is pushed or takes out of in separating brake push rod draw-in groove, realize the locking and unlocking of this separating brake lock, this direct press type separating brake lock, not only simple in structure, processing and assembly precision are less demanding, therefore production and efficiency of assembling are higher, and volume required less, go in the circuit breaker of small size, and this direct press type separating brake lock locking dependable performance.
