Herein, "a" not only means "only one", but also means "more than one".

In this document, "first", "second" and so on are only used to distinguish each other, but not to indicate their importance, order and the like.

FIG. 1 is a structural schematic diagram illustrating an exemplary embodiment of a padlock mechanism of a fuse disconnector. Fig. 2 is a sectional view along line II-II in Fig. 1 . Referring to FIGS. 1 and 2 , the padlock mechanism of the fuse disconnector includes a base 10 , an opening and closing handle 20 and a padlock 30 .

The base 10 is used to place the socket of the fuse. The opening and closing handle 20 can be pivotally connected to the base 10 , so that the fuse can be inserted into the socket of the base 10 . The pivotal connection structure between the base 10 and the opening and closing handle 20 , the structure of the socket in the base 10 , and the installation structure of the fuse in the opening and closing handle 20 can use any known method, which will not be repeated here.

The base 10 is provided with a connecting portion 12 . The opening and closing handle 20 is provided with a slot 22 . The opening and closing handle 20 and the base 10 can form a placement space 24 , and the padlock 30 can be accommodated in the placement space 24 . The slot 22 communicates with the placement space 24 .

The padlock 30 has a connecting end 32 and a padlocking end 34 . The connecting end 32 can be connected to the connecting portion 12 , and the connecting end 32 can rotate relative to the connecting portion 12 , so that the padlock 30 can rotate relative to the base 10 . As shown in Figure 1, in a schematic embodiment of the padlock mechanism of the fuse disconnector, the connecting part 12 is provided with a shaft hole 18, and the connecting end 32 is provided with an axon 322, and the axon 322 can pass through the shaft The hole 18 is used to realize the rotation of the padlock 30 relative to the base 10 . The padlock end 34 is used to connect with a padlock, so as to achieve locking between the opening and closing handle 20 and the base 10 , so that the opening and closing handle 20 cannot rotate relative to the base 10 . As shown in FIG. 1 , in a schematic embodiment of the padlock mechanism of the fuse disconnector, the padlock end 34 is provided with a lock hole 342 , and the padlock can be connected to the lock hole 342 to realize opening and closing between the handle 20 and the base 10 . lock.

Fig. 3 shows a schematic structural diagram of the padlock mechanism when the padlock is in the storage position. 1 and 3, at this time the padlock 30 is accommodated in the placement space 24, that is, between the opening and closing handle 20 and the base 10, so that the padlock will not be exposed outside the fuse disconnector, and will not Affects the overall appearance of the fuse disconnect switch.

When the padlock 30 needs to be used to lock the base 10 and the opening and closing handle 20 , the padlock 30 is pulled to rotate counterclockwise relative to the base 10 . Since the placement space 24 communicates with the slot 22 , the padlock end 34 can pass through the slot 22 during the rotation of the padlock 30 relative to the base 10 . Fig. 4 shows a schematic structural diagram of the padlock mechanism when the padlock is in the padlock position. Referring to FIG. 1 and FIG. 4 , at this time, the padlock end 34 passes through the slot 22 from the placement space 24 and is exposed to the opening and closing handle 20 , that is, the lock hole 342 of the padlock end 34 is exposed to the opening and closing handle 20 . Connecting the padlock to the lock hole 342 can realize the locking between the opening and closing handle 20 and the base 10 .

When the padlock 30 is not needed, the padlock 30 can be operated to be retracted into the storage space 24 . The process of returning the padlock member 30 from the padlock position to the storage position is opposite to the above process, and will not be repeated here.

In the padlock mechanism of the fuse isolating switch, when the opening and closing handle and the base do not need to be locked, the padlock can be stored in the placement space, so that the overall appearance of the fuse isolating switch is neat and beautiful, and the padlock is in the storage position and Switching between padlock positions is easy to operate. In addition, in the padlock mechanism, the structural changes of the opening and closing handle and the base are very small, and redesign and processing will not be required due to the addition of padlock parts.

Fig. 5 is a structural schematic diagram illustrating another exemplary embodiment of a padlock mechanism of a fuse disconnector. As shown in FIG. 5 , the connecting end 32 is provided with a first limiting portion 36 . In the embodiment shown in FIG. 5 , the first limiting portion 36 is a waist hole. The base 10 is provided with a second limiting portion 16 , and in the embodiment shown in FIG. 5 , the second limiting portion 16 is a boss. The second limiting portion 16 can be connected to the first limiting portion 36 . Referring to Fig. 3, Fig. 4 and Fig. 5, when the padlock 30 rotates relative to the base 10, the boss of the second limiting part 16 can move in the waist hole of the first limiting part 36, and pass through the first limiting part. The length of the waist hole of the portion 36 can control the rotation angle of the padlock 30 relative to the base 10 .

Referring to FIG. 4 and FIG. 5 , in an exemplary embodiment of the padlock mechanism of the fuse disconnector, the hole wall of the lock hole 342 is provided with a groove 344 . When the padlock 30 is in the storage position, the groove 344 can be exposed to the slot 22 , and the padlock end 34 can be pulled out from the placement space 24 by pulling the slot 22 . In addition, since the hole wall of the lock hole 342 is provided with a groove 344, the hole wall of the lock hole 342 where the groove 344 is set becomes thinner. When the padlock is connected to the lock hole 342 and the opening and closing handle 20 is forcibly pulled to rotate At this time, the hole wall of the lock hole 342 breaks at the place where the groove 344 is set, so that it can prompt that there is electricity theft or misoperation of the fuse isolating switch.

Fig. 6 is a sectional view along line VI-VI in Fig. 5 . Referring to FIG. 5 and FIG. 6 , the connection end 32 is provided with an abutting portion 38 . When the padlock 30 rotates relative to the base 10 , the abutting portion 38 can abut against an end surface of the base 10 facing the padlock 30 , so that the rotation of the padlock 30 is stable. In the embodiment shown in FIG. 5 , the abutment portion 38 is an abutment column.
