DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Please refer to Figures 1-4 In the embodiments of the utility model, the frame structure of the low-voltage cabinet comprises four rectangularly distributed stands 1, a plurality of crossbeams 2 are arranged between the two adjacent stands 1, the two ends of the crossbeam 2 are respectively provided with the fixing mechanism 3 for fixing the crossbeam 2 between the two adjacent stands 1, the two ends of the two adjacent sides of the fixing mechanism 3 are provided with the bolt mechanism 4 for fixing the fixing mechanism 3 on the stand 1 at the corresponding position, the fixing mechanism 3 comprises the sliding sleeve 31 slidably connected with the stand 1, the two adjacent sides of the sliding sleeve 31 are fixedly connected with the rectangular sleeve 32, the rectangular sleeve 32 is slidably connected with the plug block 33 inserted into the crossbeam 2 at the corresponding position in the inside, the plug block 33 and the rectangular sleeve 32 at the corresponding position are fixedly connected with the spring I 34

[0023] Specifically, firstly, the same number of sliding sleeves 31 are fitted onto each of the four uprights 1, and the sliding sleeves 31 are fixed to the uprights 1 at the corresponding positions using the pin mechanism 4 (in the prior art, to facilitate the installation of the crossbeams 2, the uprights 1 are usually square tubular structures with multiple round holes on their surface). Then, the two ends of the crossbeams 2 are inserted into two insert blocks 33 at the same height on two adjacent uprights 1 (in the prior art, the crossbeams 2 are usually square tubular structures). At this time, the crossbeams 2 are fixed between the two adjacent uprights 1 under the elastic action of the two springs 34 at the corresponding positions. Then, multiple crossbeams 2 are installed between two adjacent uprights 1 in the same way. When it is necessary to adjust the position of the four crossbeams 2 at a certain height... First, the four pin mechanisms 4 on the two sliding sleeves 31 at one of the crossbeams 2 of this height can be removed from the corresponding column 1. Then, by moving the two sliding sleeves 31 at this point, once the sliding sleeves 31 are moved to the installation position, the other three crossbeams 2 of this height can be moved to the installation position and fixed to the corresponding column 1 using the pin mechanisms 4. At this time, electronic components can be installed on the crossbeams 2. This device can adjust the position of the crossbeams 2 through the cooperation of the pin mechanisms 4 and the sliding sleeves 31, so that when installing electronic components, the staff can adjust the position of the crossbeams 2 according to the actual needs, and there is no need to fix the crossbeams 2 with bolts, which facilitates the quick replacement of the crossbeams 2 that are deformed by stress later.

[0024] Example 1

[0025] like Figure 3 As shown, in this embodiment, sliding holes 35 are provided on both opposite sides of the rectangular sleeve 32. A lever 36 is fixedly connected to the side of the insert block 33 corresponding to the sliding hole 35, which slides through the sliding hole 35 at the corresponding position. A limiting block 37 is fixedly connected to the outside of the insert block 33. The length and width of the limiting block 37 are the same as the length and width of the end face of the crossbeam 2, and the length and width of the end face of the insert block 33 are the same as the length and width of the end face of the crossbeam 2.

[0026] In this embodiment, the lever 36 facilitates the movement of the insert block 33 at the position controlled by the operator, thereby making it easier for the operator to insert the crossbeam 2 between the two insert blocks 33 at the corresponding position. The limiting block 37 can prevent the crossbeam 2 from moving laterally between the two columns 1 at the corresponding position, so that the crossbeam 2 can be fixed between the two insert blocks 33.

[0027] Example 2

[0028] like Figure 4As shown, in this embodiment, both ends of the sliding sleeve 31 are provided with through holes. The pin mechanism 4 includes a threaded cylinder 41 that is inserted into the through hole and the column 1 at the corresponding position. A movable column 42 is slidably sleeved inside the threaded cylinder 41. A plurality of insertion holes 411 are provided through the outer wall of the threaded cylinder 41 at equal angles. A plurality of grooves 421 are provided through the outer wall of the movable column 42 at equal angles. A locking block 43 that passes through the insertion hole 411 at the corresponding position is slidably sleeved inside the groove 421. A spring 431 is fixedly connected between the locking block 43 and the groove 421 at the corresponding position. A nut 44 is screwed onto the outer wall of the threaded cylinder 41. A spring 45 is fixedly connected between the movable column 42 and the threaded cylinder 41 at the corresponding position. A limit ring 412 is fixedly connected to one end of the threaded cylinder 41.

[0029] In this embodiment, by aligning the through hole of the sliding sleeve 31 with the round hole on the column 1, and then inserting the threaded cylinder 41 into the through hole and the round hole, and then pressing the moving column 42, the moving column 42 moves into the threaded cylinder 41 at the corresponding position until the multiple locking blocks 43 move to the insertion hole 411 at the corresponding position. Under the elastic action of the spring 431 at the corresponding position, the locking blocks 43 pop out from the groove 421 and pass through the insertion hole 411 at the corresponding position. Then, the threaded cylinder 41 is pulled outward, so that the multiple locking blocks 43 at the corresponding position are tightly against the inner side of the column 1. Then, by rotating the nut 44, the nut 44 is tightly against the outer side of the column 1 at the corresponding position, thereby fixing the sliding sleeve 31 to the column 1. When it is necessary to adjust the position of the sliding sleeve 31, the moving column 42 can be moved into the threaded cylinder 41 and the spring 45 at the corresponding position can be compressed. At this time, the locking blocks 43 are compressed and under the action of their inclined surfaces (according to...). Figure 4 As can be seen, the locking block 43 (which has a triangular structure) is retracted into the groove 421 at the corresponding position. At this time, the threaded cylinder 41 is released from its restriction. Then, the threaded cylinder 41 is pulled out from the through hole on the sliding sleeve 31. When all the threaded cylinders 41 at the sliding sleeve 31 are pulled out, the sliding sleeve 31 can be moved. After the sliding sleeve 31 is moved to the position to be installed, the threaded cylinder 41 is inserted into the through hole of the sliding sleeve 31 and the round hole on the column 1. Then, the moving column 42 is released. At this time, the moving column 42 moves in the opposite direction under the elastic action of the spring 45 at the corresponding position until the groove 421 is aligned with the insertion hole 411 at the corresponding position. At this time, the locking block 43 pops out from the groove 421 at the corresponding position and passes through the insertion hole 411 at the corresponding position. Through the cooperation of multiple locking blocks 43 and nuts 44, the device can fix the sliding sleeve 31 on the column 1 with the threaded cylinder 41, which is convenient for the staff to quickly insert and remove the threaded cylinder 41, thereby making it convenient for the staff to adjust the position of the crossbeam 2 according to the actual situation.

[0030] Example 3

[0031] like Figure 2 As shown, in this embodiment, mounting angle plates 11 are fixedly connected to both ends of the column 1.

[0032] In this embodiment, by installing the panel and cabinet door between the upper and lower mounting corner plates 11 respectively, the upright 1 and the crossbeam 2 can be installed inside the cabinet, and according to... Figure 2 It can be seen that the thickness of the mounting corner plate 11 is greater than the side thickness of the sliding sleeve 31, so that the position of the crossbeam 2 can still be adjusted after the cabinet door and panel are installed.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
