Detailed Description

The invention is further explained below with reference to the figures and examples.

Example 1

As shown in fig. 1,2 and 7, an external handle padlock device for an electrical switch cabinet comprises a handle body 1 and a padlock member 2, wherein the padlock member 2 is installed in an installation sliding groove 101 on the handle body 1 and can slide in a translational manner back and forth, and in the process that the padlock member 2 slides in the installation sliding groove 101 on the handle body 1 in a translational manner back and forth, a padlock hole 201 on the padlock member 2 can be exposed or immersed in the installation sliding groove 101 to realize corresponding padlock or unlocking; as shown in fig. 4 and 6, the latch 2 is interlocked with a locking member 6, and a hole 105 of the locking member 6 installed on the handle body 1 locks or unlocks a switch body in a vertical movement. The end surface 2601 of the latch fitting 2 linked with the locking fitting 6 is an inclined surface or a curved surface, and the upper end of the locking fitting 6 is hung on the inclined surface or the curved surface and can slide along the inclined surface or the curved surface.

The padlock part 2 can be locked and unlocked by the toggle sliding button mechanism 3 in the process of sliding back and forth in the installation sliding groove 101 on the handle body 1; the limiting piece 5 extends into the second limiting hole 204 on the padlock piece 2 from the first limiting hole 103 on the handle body 1, and can limit the padlock piece 2 to rotate and move in the installation sliding groove 101 in the reciprocating translational sliding process. The first limiting hole 103 and the second limiting hole 204 are horizontal waist-shaped holes.

The latch 2 is connected with a driving member 4 capable of driving the latch to slide out of the mounting sliding groove 101. As shown in fig. 3 and 5, in this embodiment, the driving member 4 is an elastic member, specifically, an energy storage spring 4a, which is installed in an elastic member installation groove 104 of the handle body 1, and one end of the elastic member installation groove abuts against a groove wall of the elastic member installation groove 104, and the other end of the elastic member installation groove abuts against the locking member 2, so that the locking member has a driving force to slide out of the installation sliding groove 101. Specifically speaking is as shown in fig. 1,2, 4, 6 and 8, stir slide button mechanism 3 including stir slide button body 301, stir slide button body 301 and install slide button groove 102 on the handle body 1 of installation sliding tray 101 one side can slide, stir slide button body 301 and go up and stretch out spacing boss 301a, spacing boss 301a with locking groove 202 and locking groove two 203 on the padlock piece 2 correspond, stir slide button body 301 and be connected with slide button reset spring 302 and can make it reset. One side of the limiting boss 301a corresponding to the padlock member 2 is a straight side, and the other side is an arc side to ensure that the sliding button body 301 can only slide in a single direction after being locked with the padlock member. The slide button return spring 302 is positioned in the slide button groove 102, one end of the slide button return spring is propped against the toggle slide button body 301, and the other end of the slide button return spring is propped against the groove wall of the slide button groove 102.

As shown in fig. 1 and 3, in a normal state, a padlock hole 2a at the right end of the padlock member 2 is sunk into the installation sliding groove 101 on the handle body 1, a driving member 4 is arranged in the installation sliding groove 101 at the tail end of the padlock member 2 and on the handle body 1, and an energy storage spring as the driving member 4 is compressed to be the shortest in a normal state, at this time, a limiting boss 301a for shifting the sliding button mechanism 3 is located in a first locking groove 202 on the padlock member 2, and due to the limiting effect of shifting the sliding button mechanism 3, the padlock member 2 cannot be popped out, and meanwhile, the limiting member 5 extends into a second limiting hole 204 on the padlock member 2 from a first limiting hole 103 on the handle body 1 to limit the rotation and the crosstalk of the padlock member 2 in the back-and-forth translational sliding process in the installation sliding groove 101. When stirring outwards and stirring slide button body 301, padlock 2's locking is relieved, and under the energy storage spring release effect as driving piece 4, padlock 2 slides rapidly and pops out, and padlock hole 2a exposes, as shown in fig. 2 and 4, after a stroke, stir slide button mechanism 3's spacing boss 301a and be located in lock groove two 203 on padlock 2, can carry out the padlock operation this moment. When will the unblock, promote padlock piece 2 backward along the sign on padlock hole 2a top, padlock piece 2 backs down the spacing boss 301a of stirring smooth button mechanism 3, promotes to the stroke after, and padlock piece 2 does not have handle body 1 again completely, stirs spacing boss 301a of smooth button mechanism 3 and backs up the locking groove 202 in padlock piece 2 again, and restriction padlock piece 2 pops out.

Example 2

As shown in fig. 9 and 10, in another embodiment of the present invention, the driving member 4 is a plurality of pairs of repelling or attracting

permanent magnets

4b,4 b', which are respectively riveted and installed in a permanent magnet installation groove one 205 at the end of the latch member 2 and a permanent magnet installation groove two 104 on the handle body 1, and the latch member 2 is driven to slide by magnetic force. The other structure is the same as that of the above embodiment 1, and the present embodiment is different from embodiment 1 in that after the latch member 2 is unlocked, the latch member slides out of the installation sliding groove 101 under the magnetic force of the pairs of repelling or attracting

permanent magnets

4b,4 b'.
