Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

As shown in Fig. 1 to Fig. 5, in the embodiment of the present invention, a padlock mechanism for preventing accidental removal of the switch cabinet cover plate is proposed, which cooperates with the bolt b that can fasten the switch cabinet cover plate a, including padlock d and a fitting c that fits with the padlock d; where,

Fittings c include:

The lid 1, the lid 1 includes a top surface 11 and a bottom surface 12; wherein, the top surface 11 is recessed toward the bottom surface 12 to form a recess 111; the bottom surface 12 is provided with a first padlock plate 121, and on the first padlock plate 121 There is a first lock hole 1211;

Bottom plate 2, bottom plate 2 comprises the fixed plate 21 and the second padlock plate 22 that are connected with each other; Wherein, the middle part of fixed plate 21 is provided with the through hole 211 that is used for installing bolt b, and its end away from the second padlock plate 22 passes through the rotating shaft Rotatingly installed on the top surface 11 of the lid 1; the second padlock plate 22 is provided with a second lock hole 221 matched with the first lock hole 1211, and its end away from the fixed plate 21 faces the lid 1;

When the padlock d passes through the first lock hole 1211 and the second lock hole 211 in sequence, the lid 1 and the bottom plate 2 are locked together, and the through hole 211 is located above the opening of the recess 111, so that the bolt head of the bolt b It can be located in the concave position 111.

In order to avoid the relative movement between the fitting c and the cover plate a of the switchgear, the purpose of removing the bolt b is achieved by rotating the fitting c to loosen, so an anti-rotation block is provided on the end surface of the fixing plate 21 facing away from the second padlock plate 22 212, so that the fitting c cannot be rotated.

It should be noted that, in order to facilitate the installation of the fitting c, the anti-rotation block 212 should be flush with the edge of the cover plate a of the switch cabinet, and its thickness should be smaller than the distance between adjacent switch cabinets.

Furthermore, a groove 112 is provided on one side of the recess 111, and a mounting position 1121 for the rotating shaft is provided on the inner wall of the groove 112, so that the structure of the lid 1 and the bottom plate 2 in the fitting c is more scientific and easier Install.

Correspondingly, in order to further make the structure of the lid 1 and the bottom plate 2 in the fitting c more scientific and easier to install, a protrusion 213 that can be accommodated in the groove 112 is provided on the end of the fixing plate 21 away from the second padlock plate 22 , the protrusion 213 and the second padlock plate 22 are located on the same side of the fixed plate 21, and a shaft installation hole 2131 is provided in the protrusion 213; the shaft can pass through the installation hole 2131 of the protrusion 213, and the two ends are respectively installed on The installation position 1121 of the groove 112 .

Furthermore, the depth of the recess 111 is greater than the length of the head of the bolt, so that when the lid 1 and the bottom plate 2 are locked, the head of the bolt is located in the fitting c, which facilitates the locking of the padlock mechanism. At this time, the first The first locking hole 1211 and the second locking hole 211 are on the same axis.

Furthermore, the through hole 211 is a slotted hole, so that the bolt b can be slidably installed in the through hole 211 .

Furthermore, the padlock is a mechanical or electrical locking device.

In the embodiment of the present invention, the working principle of the padlock mechanism for preventing the cover plate of the switch cabinet from being dismantled by mistake is as follows: firstly, after assembling the box cover 1 and the bottom plate 2 of the fitting c, they are inserted between adjacent switch cabinets, and the anti-rotation The stopper 212 is arranged flush with the edge of a switch cabinet cover a; secondly, the bolt b penetrates the through hole 211 on the fixing plate 21 and is fixed with the switch cabinet cover a, and the box cover 1 of the fitting c is turned over Move towards the bottom plate 2 until the top surface 11 of the box cover 1 fits with the end surface of the fixed plate 21 on the bottom plate 2, and pass through the first lock hole 1211 and the second lock hole 211 in turn through the padlock d to realize the box cover 1 and the bottom plate 2-phase locking, so that the head of the bolt b is located in the concave position 111. Open the padlock d, take out the padlock d from the first lock hole 1211 and the second lock hole 211, turn over the cover 1 of the matching part c to move away from the bottom plate 2, and realize the separation of the box cover 1 and the bottom plate 2, so that it can be disassembled by tools The cover plate a of the switch cabinet fastened by the bolt b.

Implementing the embodiment of the present invention has the following beneficial effects:

In the embodiment of the present invention, since the padlock mechanism includes a padlock and a matching piece matched with the padlock, the bolts for fastening the switch cabinet are located on the through holes on the fixing plate of the fitting piece, so the padlock can lock the matching piece before maintenance, so that The head of the bolt is located in the box cover of the matching parts, and the padlock and the matching parts are opened in turn during the maintenance process. Remove the cover of live switchgear by mistake to avoid the risk of personal injury.

The above disclosure is only a preferred embodiment of the present invention, which certainly cannot limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
