The hanging plate 10 is simple and convenient to operate integrally, is not easy to fall off after being hung, and is high in safety.
The upper lock shell 21, the lower lock shell 22 and the lock ring 23 may be arc-shaped, and a padlock cavity defined by the three is circular. Also, the lock ring 23 may be provided with a spring hole 233 to which the energy storage spring 25 is hooked.
In other embodiments, please refer to fig. 1 to 3, further comprising a locking assembly 30; an opening hole 231 is provided on the lock ring 23 near the front end, and a locking hole 232 is provided near the rear end.
The locking assembly 30 includes: a stop spring 31 and a stop slider 32; the clamping slide block 32 is arranged on the hanging plate 10 in a sliding way; the two ends of the locking spring 31 are respectively connected with the locking slide block 32 and the hanging plate 10, and are used for providing elastic force for driving the locking slide block 32 to approach the locking ring 23 for the locking slide block 32; the locking slider 32 is configured to be locked with the locking hole 231 in the unlocked state and to be locked with the locking hole 232 in the locked state.
In the present embodiment, the locking assembly 30 composed of the locking spring 31 and the locking slider 32 serves as a stopper of the lock ring 23. When the stop slider 32 is engaged with the open hole 231 or the closed hole 232, the lock ring 23 is restricted from sliding.
Specifically, in the unlocking state, referring to fig. 2, the locking slider 32 extends into the unlocking hole 231 and is locked with the unlocking hole 231, so that the lock ring 23 cannot move and the padlock assembly 20 keeps the opening state. When the padlock is locked, after the locking slider 32 is pulled to slide out of the unlocking hole 231, the shackle 23 slides to the front end by the thrust of the energy storage spring 25 to abut against the upper lock case 21 to enter the locking state, and at the moment, the locking slider 32 is just clamped into the locking hole 232, so that the shackle 23 cannot slide back and forth, and the padlock assembly 20 keeps the locking state.
In a further improved embodiment, in order to facilitate driving the locking slider 32 to slide, an operation ring 321 may be disposed on the locking slider 32, so as to facilitate pulling by a worker.
Further, the operation ring 321 is connected with a locking tab 50 through a rope 51. The locking tab 50 allows a worker to slide the locking tab 32 by inserting an operator, such as an insulated rod, into the locking tab 50 when it is desired to hang the padlock assembly 20 in the upper position.
As a further improvement, the rear end of the upper lock case 21 is rotatably connected to the rear end of the lower lock case 22. Specifically, the upper lock case 21 and the lower lock case 22 can be rotatably connected by the nut 60, so that the upper lock case 21 and the lower lock case 22 which are dislocated cannot be separated from each other after the blocking member 24 is removed, thereby facilitating the secondary use of the padlock assembly 20.
In a further modified embodiment, please refer to fig. 2, further comprising a lever 70; the operation ring 321 is connected with a rubber plug 322, and the operation ring and the rubber plug can be connected through a string; a cylinder 72 is arranged on the top of the operating rod 70; the barrel 72 is used for movably inserting the rubber stopper 322.
Specifically, the interference fit between the rubber stopper 322 and the barrel 72 is such that pulling the rubber stopper 322 out of the barrel 72 requires a greater pulling force than the barrel 72. During the process of pulling the rubber stopper 322 out of the cylinder 72, the rubber stopper 322 provides a downward pulling force to the operation ring 321, so that the locking slider 32 slides out of the unlocking hole 231 or the locking hole 232.
It should be noted that the lever 70 may be provided with a cross bar 71 for engaging the locking tab 50.
Accordingly, an unlocking tab 241 may be connected to the detent member 24. The unlocking tab 241 may be used to engage the crossbar 71 on the lever 70 to facilitate the unlocking of the padlock assembly 20 by a worker through the lever 70.
Further, the locking ring 23 is provided with an operating handle 234; the operating handle 234 extends outside the lower lock case 22.

The sliding of the locking ring 23 by the operator is facilitated by the handle 234. Accordingly, the operating handle 234 may be annular in shape into which the crossbar 71 may extend.
Furthermore, the hanging plate is provided with a plurality of hanging holes 11 for connecting with the warning board 40. Wherein, the warning board 40 can be connected with a plastic plug 41 for connecting with the hanging hole 11.
The warning board 40 can be integrally sprayed with yellow and red marks, which is convenient for operators to find. The signboard can select red cassette in the operation, and the signboard can rotate green suspension cassette in the maintenance, and the signboard can select yellow cassette in the operation. And three-phase colors can be selected for adjustment according to field conditions.
Further, the locking member 24 may be a corrugated unlocking rope, and the length of the locking member 24 extending into the lower and upper through holes is adjusted according to the field situation. The longer the retaining member 24 extends into, the firmer the lock catch is, and the less susceptible to external physical factors. And the unlocking is only longer in the pulling-out length, so that the operation difficulty cannot be increased. Meanwhile, in order to prevent the detent member 24 from being lost after falling, the detent member 24 and the lower lock case 22 or the upper lock case 21 may be connected by a cord 242.
Although the present invention has been described in detail with reference to examples, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention.
