The objective of the invention is to realize by following technical solution: a kind of isolating switch fuse group, include isolating switch body and fuse, the isolating switch body includes housing, rotating shaft and dynamic and static contact, dynamic and static contact is closed with the rotation of rotating shaft, disconnection cooperates, fuse includes base and opening, is characterized in being provided with interlocking device between described rotating shaft and the opening.
Described opening is provided with lock hook, and the relevant position is provided with the locking bar that is linked with rotating shaft, and locking bar locks, separates the interlocking device that cooperates formation above-mentioned with the rotation of rotating shaft with lock hook.
Housing be provided with groove with the lock hook corresponding section, the locking bar slip is set in the groove, be provided with the cam that cooperates with locking bar with respect to the locking bar position in the rotating shaft, the close rotating shaft position of locking bar is provided with boss, is provided with to order about locking bar elasticity and be pressed on compression spring on the cam surface between the end face of boss and groove.
Be provided with the rotating part that ends that cooperates with its formation axial displacement, circumferential relative fixed at housing bottom, only be provided with between the lower end of rotating part and the housing bottom side to order about and end the elastic component of rotating part to top offset, be provided with the roof pressure face that presses down for opening in the upper end of ending rotating part, end rotating part and constitute described interlocking device with moving and move down with rotating shaft rotation screens on it or breaking away to cooperate.
Side is provided with the T-shape groove in the bottom of housing, ending the rotating part slip is set in " T " constitute above-mentioned axial displacement in the type groove, circumferentially relative fixed cooperates, be provided with the extension that extends to rotating shaft place in the bottom of ending rotating part, extension cooperates with the formation rotation screens or the disengaging of rotating shaft.
Avris at extension is provided with the upwards flanging of turnover, and flanging constitutes above-mentioned rotation screens with the rocking arm of rotating shaft or disengaging cooperates.
The invention has the beneficial effects as follows: the interlocking device that utilizes rotating shaft and opening, only make rotating shaft at isolating switch rotate to open position and just can open the fuse opening, thereby can change fuse element, perhaps when opening the fuse opening, isolating switch can't close a floodgate, thereby has guaranteed the safety that fuse uses.

Embodiment
Now in conjunction with the accompanying drawings the present invention is further described:
As shown in the figure as can be known, a kind of isolating switch fuse of the present invention group, include isolating switch body 1 and fuse 2, isolating switch body 1 includes housing 11, rotating shaft 12 and moving, fixed contact, moving, fixed contact is closure with the rotation of rotating shaft 12, disconnect and cooperating, fuse 2 includes base 22 and opening 21, usually fuse element is located at opening 21, described opening 21 is provided with lock hook 211, the housing 111 of lock hook 211 tops be provided with groove 1111 (as shown in Figure 2), locking bar 4 slips are set in the groove 1111, the upper end 411 that is provided with locking bar 4 with respect to locking bar 4 positions in the rotating shaft 12 (preferably is set as round slip surface, to reduce friction) cam 121 (as shown in Figure 5) that cooperates, close rotating shaft 12 positions of locking bar 4 are provided with boss 41, are provided with to order about locking bar 4 elasticity and be pressed on compression spring 3 on the cam surface 121 between the end face 1112 of boss 41 and groove 1111; When the rotating shaft 12 that turns clockwise (even isolating switch combined floodgate), cam surface 121 drives locking bars 4 and moves down and make it to slide onto on the lock hook 211 and block lock hook 211 opening 21 can't be opened, only when being rotated counterclockwise rotating shaft 121 (promptly disconnecting isolating switch), under the effect of compression spring 3, locking bar 4 moves up and makes its lower end leave lock hook 211, thereby just can open opening 21, to realize changing the needs of fuse element, promptly realize the interlocking between rotating shaft 12 and the opening 21, guaranteed the safety of using.Originally executing in the example, locking bar is that employing is telescopic, can certainly adopt rotary, promptly rotate (as the mode that adopts and rotating shaft is wholely set) with rotating shaft, when isolating switch closed a floodgate, lock hook was pinned at precession to lock hook place to locking bar with the rotating shaft rotation, and when disconnecting isolating switch, locking bar screws out lock hook with rotating shaft, and opening promptly can be opened.
Consider after opening opening, can have also that the staff dredges and with the situation of isolating switch combined floodgate, and can exist dangerous equally if after isolating switch closes a floodgate, cover opening again, therefore be provided with at the bottom of housing 11 side " T " type groove 112 (as shown in Figure 6), ending rotating part 6 slips is set in " T " constitute the axial displacement that ends between rotating part 6 and the housing 11 in the type groove 112, circumferentially relative fixed cooperates, the lower end of ending rotating part 6 with " T " be provided with between type groove 112 bottom sides to order about and end rotating part 6 (elastic component is generally spring 5 to the elastic component of top offset, can certainly be shell fragment), be provided with the roof pressure face 61 that presses down for opening 21 in the upper end of ending rotating part 6, be provided with the extension 62 that extends to rotating shaft 12 places in the bottom of ending rotating part 6, avris at extension 62 is provided with the upwards flanging 621 of turnover, when covering opening 21, lock hook 211 lower surfaces of opening 21 press down roof pressure face 61 and make only that rotating part 6 overcomes the elastic force of spring 5 and moves down, the upper surface of ending the flanging 621 of rotating part 6 promptly is in the horizontal plane below of rocking bar 122 (as Fig. 7, shown in Figure 8), thereby rotating shaft 12 can turn clockwise, be that isolating switch can close a floodgate, and when opening opening 21, spring 5 will end upwards jack-up of rotating part 6, thereby the upper end surface of flanging 621 is in the top of the horizontal plane of rocking bar 122, thereby blocking rotating shaft 12 can not turn clockwise it, be that isolating switch can't close a floodgate, further realize the interlocking between rotating shaft 12 and the opening 21, thereby further guaranteed the safety of using.Certainly, the present invention also can with end rotating part be arranged on rotating shaft under, utilization establishes in housing that square guide groove makes only between the rotating part and housing can axial slip and circumferentially can not rotate relatively, and on the rotating shaft lower surface, be provided with eccentric jack, end rotating part above establish a boss (or latch) with respect to jack position, when opening opening, under the compression spring action, make only and to move on the rotating part and its pin bushing inserts in the jack, thereby rotating shaft promptly cannot be rotated, and only makes only rotating part move down its latch to break away from jack and just can rotate covering opening; Perhaps will end the outside that rotating part is set as hollow is square spline-like, and the corresponding spline of establishing on the lower surface of rotating shaft is so that spline and reach the purpose of the locking that rotates in a circumferential direction cooperating of spline.
