DETAILED DESCRIPTION

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a high-safety wiring distribution cabinet, including a distribution cabinet 1, a cabinet door 11 is provided on the distribution cabinet 1, a heat exhaust hole 12 is provided on the distribution cabinet 1, and a wire hole 13 is provided on the distribution cabinet 1. There are two wire holes 13, which are responsible for the entry and exit of the line;

[0028] It also includes a mounting structure arranged inside the power distribution cabinet 1 and having a spacing adjustment function;

[0029] The mounting structure includes a first mounting plate 21 fixed in the power distribution cabinet 1, the upper part of the first mounting plate 21 is directly fixedly connected to the inner wall of the power distribution cabinet 1, a second mounting plate 22 is arranged at the lower side of the first mounting plate 21, and multiple second mounting plates 22 can be installed as needed, a connecting sleeve 23 fixed to one side of the second mounting plate 22, a threaded sleeve 24 movably connected to the inner side of the connecting sleeve 23, the inner side of the threaded sleeve 24 has a thread that cooperates with the screw rod 25, and the threaded sleeve 24 is an active part, and the operator needs to manually rotate the threaded sleeve 24, the screw rod 25 arranged on the inner side of the threaded sleeve 24, and the fixing blocks 26 fixedly connected to the two ends of the screw rod 25, and the fixing blocks 26 are fixed to the inner wall of the power distribution cabinet 1.

[0030] An embedding block 27 is fixedly connected to the outer side of the threaded sleeve 24 , and an annular groove is provided inside the connecting sleeve 23 for limiting the threaded sleeve 24 with the embedding block 27 .

[0031] A square hole 28 is provided on the second mounting plate 22, and a limiting rod 29 is fixedly connected to the first mounting plate 21. The second mounting plate 22 is slidably connected to the limiting rod 29 through the square hole 28. The limiting rod 29 and the square hole 28 cooperate between the second mounting plate 22 and the first mounting plate 21 so that the second mounting plate 22 can only be displaced along the direction limited by the limiting rod 29.

[0032] A slide groove 210 is provided on one side of the second mounting plate 22, and a slider 211 is fixedly connected to the second mounting plate 22. The slide groove 210 and the slider 211 cooperate to limit the positional relationship between the second mounting plate 22 and the distribution cabinet 1. Through the cooperation of the limit rod 29 and the square hole 28 and the slider 211 and the slide groove 210, the second mounting plate 22 will not be offset during the unique process.

[0033] A busbar duct 212 is provided on the first mounting plate 21 , and a busbar duct 212 is also provided on the second mounting plate 22 . The busbar duct 212 is used to install the busbars, and a locking structure is provided on the connecting sleeve 23 .

[0034] During use, first measure the length of the busbar to be used, and then rotate the threaded sleeve 24. Because the threaded sleeve 24 and the screw rod 25 are threadedly connected, and the screw rod 25 is fixed in the distribution cabinet 1 by the fixing block 26, rotating the threaded sleeve 24 will cause the threaded sleeve 24 to move axially along the screw rod 25. Because a connecting sleeve 23 is nested on the outside of the threaded sleeve 24, and the connecting sleeve 23 is fixedly connected to the second mounting plate 22, the second mounting plate 22 will move following the connecting sleeve 23, that is, the second mounting plate 22 will move following the threaded sleeve 24. Because the limiting rod 29 and the square hole 28 as well as the slider 211 and the slide groove 210 limit the second mounting plate 22, the second mounting plate 22 will move up and down following the threaded sleeve 24 just below the first mounting plate 21. After the adjustment is completed, the position of the second mounting plate 22 is locked by the locking structure, and then the busbar, air switch and other equipment can be installed in the bus duct 212.

[0035] Example 2

[0036] Reference Figure 1-4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the locking structure includes a fixing groove 31 opened on the connecting sleeve 23, the fixing groove 31 is located on the upper surface of the connecting sleeve 23, the fixing groove 31 has a square groove of a certain depth, the position is fixed and there is only one L-shaped locking block 32 arranged on the connecting sleeve 23, the long rod part of the L-shaped locking block 32 is used to be inserted into the fixing groove 31, and the short rod part is used to be clamped in the locking groove 33, and the locking groove 33 opened on the threaded sleeve 24 has multiple locking grooves 33, the number of which can be adjusted according to needs, and they are evenly opened on the threaded sleeve 24.

[0037] The locking groove 33 of the threaded sleeve 24 is inserted into the locking groove 33, and the long rod part 31 is inserted into the fixing groove 31, so as to fix the threaded sleeve 24, thereby ensuring that the threaded sleeve 24 does not rotate or move, and the position of the second mounting plate 22 can be fixed. In addition, the size of the locking groove 33 can be changed according to the size of the fixing groove 31. When the locking groove 33 becomes smaller, more locking grooves 33 can be opened on the threaded sleeve 24, thereby increasing the rotation angle of the threaded sleeve 24 in the locked position, thereby controlling the displacement accuracy of the second mounting plate 22, and increasing its selectivity for the busbar length.

[0038] The remaining structures are the same as those of Example 1.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
