DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides a spliced ​​low-voltage cabinet, comprising:

[0028] A lower cabinet 1 and an upper cabinet 4, wherein the inner wall of the lower cabinet 1 is provided with a connecting mechanism 2 for connecting to the upper cabinet 4;

[0029] The connecting mechanism 2 includes a connecting groove 21, which is provided on the inner wall of the lower cabinet 1, and a spring 22 and a connecting pipe 23 are fixedly installed in the inner cavity of the connecting groove 21;

[0030] A baffle plate 24 is welded to one end of the spring 22, and a connecting rod 25 is rotatably connected to one side of the baffle plate 24;

[0031] A connecting frame 26 is welded to one end of the connecting rod 25 , and an insert block 27 is fixedly mounted on the upper portion of one side of the connecting frame 26 . A groove 28 is formed on the inner wall of the upper cabinet 4 , and the insert block 27 is inserted into the groove 28 .

[0032] The picture shows the installation status:

[0033] When disassembling:

[0034] Pull the connecting frame 26 directly outward. Since the middle of the connecting frame 26 is hollowed out, it is convenient for the user to pull the connecting frame 26. After the connecting frame 26 is pulled, the connecting rod 25 and the insert block 27 will be driven to move together.

[0035] When the connecting rod 25 moves, it will directly pull the baffle 24 to move inside the connecting tube 23. At the same time, the connecting tube 23 will stretch the connecting frame 26 during the sliding process, and the connecting rod 25 and the connecting tube 23 are in a sliding penetration state until the baffle 24 can no longer be pulled.

[0036] When the plug block 27 is pulled synchronously until it is out of the groove 28, the connecting frame 26 can be rotated to drive the connecting rod 25 to rotate together until the plug block 27 is rotated from the top to the bottom, and the connecting mechanism 2 in the opposite direction can be operated as described above, and then the upper cabinet 4 can be directly removed upwards;

[0037] Preferably, the inner walls of the lower cabinet 1 and the upper cabinet 4 are both provided with a merging mechanism 3 for parallel connection, and the merging mechanism 3 includes an insertion component and a locking component, the insertion component is arranged on the inner walls of the lower cabinet 1 and the upper cabinet 4, and the locking component is arranged inside the insertion component.

[0038] like Figure 4 and 5 As shown, the insertion component includes a through hole 31, which is opened on the inner wall of the lower cabinet 1 and the upper cabinet 4. A through pipe 32 passes through the inside of the through hole 31, and a cross plate 33 is fixedly installed on the outer side of one end of the through pipe 32, which is conducive to cooperating with the locking component to realize parallel connection of the two groups of low-voltage cabinets after splicing.

[0039] like Figure 4 and 5 As shown, the locking assembly includes a threaded tube 34, which is inserted into the interior of the through tube 32. A fixing plate 35 is fixedly installed at one end of the threaded tube 34. The internal thread of the threaded tube 34 is connected to a screw 36, which plays the role of inserting the thread locking operation after pre-connection, and easily fixes the two groups of spliced ​​low-voltage cabinets.

[0040] like Figure 2 The figure shows the installation status. This step needs to be performed after the above low-voltage cabinets are spliced. It is mainly used to place several groups of low-voltage cabinets in parallel to reduce the floor space.

[0041] While operating:

[0042] First, place the two groups of spliced ​​low-voltage cabinets in a close fit, then take out the through-tube 32 to drive the horizontal plate 33 to move, and pass the through-tube 32 through the wall thickness of the contact surface of the two groups of low-voltage cabinets, then take out the threaded tube 34, use the threaded tube 34 to drive the fixed plate 35 to move, and insert the threaded tube 34 into the inside of the through-tube 32 to make the two connected throughly, finally take out the screw rod 36 and align it with one end of the threaded tube 34, and rotate the screw rod 36 clockwise. At this time, the screw rod 36 is threadedly connected to the threaded tube 34 until the two groups of fitted low-voltage cabinets are tightened. In this way, the upper and lower parts can be fixedly connected at the same time to realize the parallel connection of two groups of low-voltage cabinets. If more low-voltage cabinets need to be connected in parallel, they can be operated in sequence according to the above method.

[0043] Among them, an adapter groove 6 is opened on the top of the lower cabinet 1, and a connecting frame 7 is fixedly installed on the bottom of the upper cabinet 4. The connecting frame 7 is inserted into the inside of the adapter groove 6, which is beneficial for the lower cabinet 1 to support and limit the upper cabinet 4 when splicing the upper cabinet 4 and the lower cabinet 1. During splicing, the upper cabinet 4 needs to be placed on the top of the lower cabinet 1 and the connecting frame 7 needs to be inserted into the adapter groove 6 to realize the position positioning operation to prevent displacement.

[0044] Among them, the outer sides of the lower cabinet 1 and the upper cabinet 4 are both provided with heat dissipation holes 5, and the inner walls of the lower cabinet 1 and the upper cabinet 4 are fixedly installed with mounting plates 8. The heat dissipation holes 5 are mainly used for heat dissipation, and the mounting plates 8 are conducive to carrying the electrical equipment or components required for installation.

[0045] In addition, the spring 22 is located inside the connecting tube 23 , and one end of the connecting rod 25 is fixedly passed through one end of the connecting tube 23 .

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
