Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Example 1: referring to fig. 1-4, a switch cabinet convenient for maintenance includes laminates 11, columns 12 fixed between the laminates 11, and side plates 13 located around the laminates 11, wherein the columns 12 are rotatably connected with door panels 14, the columns 12 are horizontally fixed with slide rails 21, and the side plates 13 are fixed with slide bars 22 connected to the slide rails 21 in a sliding manner, so that the side plates 13 can only slide along the length direction of the slide rails 21, but cannot move along other directions. Four bolts 4 are arranged on the side plate 13 along the direction perpendicular to the side plate 13, the bolts 4 are located at four corners of the side plate 13, when the bolts 4 are simultaneously inserted on the side plate 13 and the upright post 12, the bolts 4 are perpendicular to the direction of the sliding rail 21, an interlocking structure is formed on the side plate 13, so that the side plate 13 is fixed on the upright post 12, a limiting part 3 for preventing the bolts 4 from being separated from the side plate 13 is further arranged on the side plate 13, when the bolts 4 are inserted in the limiting part 3, the bolts 4 cannot be separated from the upright post 12 and the side plate 13, and the connection firmness between the side plate 13 and the upright post 12 is ensured.

The implementation principle of the above embodiment is as follows: the side plate 13 is connected to the upright post 12 in a sliding manner through the sliding rail 21 and the sliding rod 22, and the side plate 13 is fixed to the upright post 12 in a plug-in locking manner through the plug pin 4, so that the side plate 13 is convenient to disassemble quickly, a larger maintenance space can be obtained, and the maintenance of the electrical elements is convenient.

Embodiment 2, referring to fig. 3 to 4, the limiting member 3 includes a fixing sleeve 31 and a limiting block 32 located at an outer end of the fixing sleeve 31, and the fixing sleeve 31 is fixed on the side plate 13 by a threaded connection. The limiting blocks 32 are arranged on the fixing sleeve 31 in a plurality of arrays, and the limiting blocks 32 and the fixing sleeve 31 are integrally arranged. The gap between the limiting block 32 and the limiting block 32 is as large as the limiting block 32, a plurality of stoppers 41 are integrally arranged on the bolt 4, and the stoppers 41 and the limiting block 32 have the same shape and are as large as each other. The stopper 41 passes through the free space between the adjacent stoppers 32, and then the bolt 4 is rotated, so that the stopper 41 can be overlapped with the stoppers 32, thereby limiting the axial movement of the stopper 41 along the bolt 4, and further limiting the bolt 4 in the fixing sleeve 31 to prevent the bolt 4 from being separated from the upright 12.

Referring to fig. 3-4, a spring 34 is arranged in the fixing sleeve 31, the bolt 4 is sleeved in the compression spring 33, and when the bolt 4 is inserted in the fixing sleeve 31, the compression spring 33 is squeezed to press the stopper 41 against the limiting block 32. Like this to dog 41 application pretightning force for dog 41 and stopper 32 can support tightly together, increase the frictional force between dog 41 and the stopper 32, prevent that dog 41 and stopper 32 from staggering.

Referring to fig. 3-4, the locking member 5 for limiting the staggering between the stopper 41 and the limiting block 32 slides on the bolt 4, the locking member 5 comprises a ring sleeve 51 sleeved on the bolt 4 and an inserting plate 52 fixed on the ring sleeve 51 and used for being inserted between the adjacent limiting blocks 32, and the size and shape of the inserting plate 52 are the same as the shape and size of the free space between the adjacent limiting blocks 32. When the locking member 5 is inserted into the empty space between the adjacent stoppers 32, the stopper 41 and the latch 4 cannot rotate, thereby further preventing the latch 4 from being separated from the upright 12 in an artificial way.

Referring to fig. 3-5, an arc-shaped spring 34 is arranged in the fixed sleeve 31, a convex block is fixedly arranged in the fixed sleeve 31, one end of the spring 34 abuts against the convex block, the other end of the spring is used for abutting against the stop block 41, when the stop block 41 is overlapped with the limiting block 32, the spring 34 is extruded, when the locking member 5 is separated from the fixed sleeve 31, the pressure spring 33 abuts against the stop block 41, the bolt 4 automatically rotates to a position between the adjacent limiting blocks 32, and at this time, the bolt 4 can automatically separate from the upright post 12 under the action of the pressure spring 33. In conclusion, at this time, the locking member 5 is pulled out, so that the bolt 4 can be automatically separated from the upright post 12, and the operation is more convenient.

The action process is as follows: the side plate 13 is connected to the upright post 12 in a sliding manner through the sliding rail 21 and the sliding rod 22, and the side plate 13 is fixed on the upright post 12 in an inserting and locking manner through the bolt 4, so that the side plate 13 is convenient to disassemble quickly, a larger maintenance space can be obtained, and the maintenance of electric elements is convenient; when the bolt 4 is disassembled, the bolt 4 can be automatically separated from the upright post 12 only by pulling out the locking piece 5, and the side plate 13 can slide.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
