As shown in Fig. 4 and 7, what the specific embodiment of the invention provided manually comprises handle 1 and main body 2 with electronic conversion knob, wherein,
Cylinder 2 is installed in rotation in described reclosing mechanism, this main body 2 arranges with handle 1 interlock, to rotate under the drive at handle 1, be formed with the helical orbit 4 extended along its axial direction on the outer wall 3 of cylinder 2, helical orbit 4 can coordinate to realize that described bidentate batten changes between different working modes with the bidentate batten of reclosing mechanism.
Therefore, after this conversion knob vertically is assemblied in reclosing mechanism, helical orbit 4 can coordinate with the bidentate batten of reclosing mechanism, because cylinder 2 can rotate, helical orbit 4 will form the movement locus on screw, and the bidentate batten will be under the effect of this helical orbit, can rotate around the one end, thereby realize that this bidentate batten changes between different working modes, for example, the screw rod of bidentate batten and motor engagement or break away from.When this conversion knob can meet above-mentioned functions, simple in structure, easily processing.
In reality, the length of the helical orbit 4 on cylinder 2, the whole circumferential lengths from its top to its terminal can be determined according to self size of bidentate batten, the diameter of motor screw and the matching relationship of bidentate batten and motor screw, but on the whole, the length of helical orbit 4 should guarantee the bidentate batten can be between its different working modes fully conversion get final product.
In addition, as shown in Figure 7, when helical orbit 4 coordinates with bidentate batten 10, in order to meet the flexible movement of bidentate batten, be not subject to the resistance of helical orbit 4, to realize breaking-closing operating accurately, preferably, distance between the top side face of helical orbit 4 and bottom side should be guaranteed when described bidentate batten coordinates with described helical orbit 4, described bidentate batten does not bend, particularly, as shown in Figure 7, although bidentate batten 10 forms and contacts with helical orbit 4 with the second contact point 12 at first make contact 11, but under this state, bidentate batten 10 can not bend.
And in practice, the distance between the top side face of helical orbit 4 and bottom side can be carried out corresponding adjustment according to the bidentate batten of different size.
In the actual shaping of helical orbit 4, helical orbit 4 can be for being formed in the helical groove on described outer wall 3, specifically as shown in Figures 4 and 5, or can be for being formed on described outer wall 3 and outward extending spiral salient (not shown).
Preferably, in the situation that helical orbit 4 is spiral salient, form good coordinating in order to make bidentate batten and helical orbit, the shape of cross section of described spiral salient is rectangle, like this, the end face of this rectangle will form with the bottom surface of bidentate batten good matching relationship.
In addition, when electronic divide-shut brake, the bidentate batten will form and coordinate with the inlet portion of helical orbit, and simultaneously, this bidentate batten also forms engagement with the screw rod of motor.But, in order to realize motor screw, with the bidentate batten, coordinate accurately, preferably, as shown in Figure 5, described cylinder 2 is flat shape away from the bottom side 5 of the inlet portion of the described helical orbit 4 on the end of described handle 1.Like this, when the sidepiece of bidentate batten coordinates with the bottom side of this flat shape 5, the bidentate batten will keep level straight, with and the screw rod of motor between form accurate engagement, can realize the reliable electronic divide-shut brake of reclosing mechanism.
Further, when the length of the bottom side 5 of described flat shape should guarantee that described bidentate batten coordinates with the bottom side 5 of described flat shape, described bidentate batten can keep level straight, when making the horizontal translation on this flat shape of bidentate batten moving, can with the screw rod of motor between form good stable coordinating.
In addition, the edge of described helical orbit 4 is formed with chamfering 6, to facilitate face that helical orbit coordinates with the bidentate batten, can be screwed into smoothly the bottom surface of bidentate batten.
In addition, as shown in Figure 6, on the end face 7 of described cylinder 2 away from described handle 1, have mating holes 8, this mating holes 8 can coordinate with the fulcrum in reclosing mechanism, so that this conversion knob can be installed and reclosing mechanism rotationally.
Below describe several fit systems of handle 1 and cylinder 2 of the conversion knob of the specific embodiment of the invention in detail; but should be understood that; it is not restricted to the mode of the following stated; those skilled in the art can replace accordingly it, revise or change; as long as these mechanisms that replace, revise or change can realize that handle can drive the function that cylinder 2 rotates, just fall in the protection range of the claims in the present invention.
Mode one:
In this mode one, handle 1 directly is connected and is coaxially set with cylinder 2, and like this, handle 1 and cylinder 2 rotate simultaneously, to realize the conversion of bidentate batten between different working modes by helical orbit 4.
The mode that cylinder 2 can be threaded connection is connected with handle 1.Simultaneously, do not do any restriction in this shape to handle 1.
Mode two:
In this mode two, as shown in Figure 4, described handle 1 is connected with described cylinder 2 by connecting rod 9, and this three is coaxially set, the radial dimension of described connecting rod 9 is less than the diameter of described cylinder 2, like this, by connecting rod 9, can meet this conversion knob being suitable in the reclosing mechanism of differing heights.
In addition, the length of connecting rod 9 is set to regulate, or is set to scalable mode, thereby makes the installation of this conversion knob not be subject to the restriction of reclosing mechanism installing space height.
Mode three:
In this mode three, although the connected mode of not shown handle 1 and cylinder 2 in accompanying drawing,, by following detailed text description, those skilled in the art should understand.
In this mode, the first gear is installed on the upper end that is not provided with helical orbit 4 of cylinder 2 or is formed with the first tooth on the outer circumference surface of this upper end; The second gear meshed with described the first gear is installed on the end that accordingly, handle 1 and cylinder 2 cooperatively interact or is formed with the second tooth meshed with described the first tooth on the excircle of this end.Preferably, described gear or tooth are spur gear or straight-tooth.
Like this, handle 1 is connected with the non-coaxial line of cylinder 2, and it is limited that the conversion knob of this fit system is applicable to the height installing space, and the reclosing mechanism that laterally installing space allows.By the cooperation of gear or tooth, turning handle 1 can drive cylinder 2 and rotate, and realizes that the bidentate batten changes between different working modes.
In three kinds of modes of foregoing description, handle 1 mainly is applicable to the situation arranged on the top of reclosing mechanism.
In addition, as other selectable a kind of modes, handle 1 is bar shape, and its position coordinated with cylinder 2 for example is formed with tooth bar on surface, and cylinder 2 is not provided with on the upper end of helical orbit 4 and gear is installed or is formed with tooth on the outer circumference surface of this upper end.Like this, the tooth bar of handle 1 just can with cylinder 2 on described gear or tooth engagement, drawing handle 1 can drive cylinder 2 and rotate.This mode mainly is applicable to the situation that handle 1 is installed at the sidepiece of reclosing mechanism.
Below explanation is of the present invention is somebody's turn to do manually and the course of work of electronic conversion knob:
When reclosing structure electric divide-shut brake, the bidentate batten coordinates with bottom side 5, and like this, when motor positive and inverse moves, the meshing relation that motor screw and bidentate batten form will make the bidentate batten move on bottom side 5, thereby realize electronic breaking-closing operating.
When product runs into power failure and maybe needs to overhaul, need to take manual mode to carry out divide-shut brake.Now, only need turning handle 1, driving cylinder 2 rotates, make helical orbit 4 form screw upwards, to force the bidentate batten to rotate around the one end, until bidentate batten and motor screw break away from engagement fully, now, manually the operating grip of running circuit breaker, can realize manual breaking-closing operating.
Otherwise, when cylinder 2 rotates backward, will make the bidentate batten again mesh with motor screw, can realize electronic breaking-closing operating again.
Obviously, above-described embodiment is only for example clearly is described, is not the restriction to execution mode.Concerning those of ordinary skill in the field, also can make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And the apparent variation of being extended out thus or change are still among the protection range in the invention.
