Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet crossbeam which is easy to install. Background Art

[0002] A distribution cabinet is the final stage of a power distribution system, used in applications with dispersed loads and a limited number of circuits. It distributes power from a circuit in the previous distribution equipment to the nearest load. A distribution cabinet typically houses numerous electrical components, including fuses and circuit breakers for overload and short-circuit protection, contactors and relays for remote control and signal conversion within the distribution circuit, as well as digital sensors, meters, and displays. To facilitate the installation of these components and facilitate circuit routing, a crossbeam is typically installed at the rear end of the cabinet, upon which these components are mounted.

[0003] For example, Chinese patent number CN207782150U discloses an electrical appliance mounting rack for a distribution cabinet, in which a plurality of parallel horizontal transverse beams, namely the above-mentioned transverse beams, are detachably connected to the vertical longitudinal beams. As can be seen from the diagram, the transverse beams and the longitudinal beams are installed by bolts. However, in actual use, the inventor found that it is necessary to hold the transverse beam continuously with the hand, and to align the threaded holes at both ends of the transverse beam with the threaded holes on the longitudinal beam, which will invest a lot of time and labor costs, and is relatively laborious. After the installation is completed, the position of the transverse beam needs to be checked. If the position of a certain transverse beam deviates, it will take more time to replace the position of the transverse beam. Utility Model Content

DETAILED DESCRIPTION

[0029] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0030] Example

[0031] As mentioned in the background technology, in order to facilitate the installation of electronic components in the distribution cabinet, it is necessary to lay out the installation beam 1 in advance in the distribution cabinet, and install the electronic components on the beam 1. The existing installation method of the beam 1 is usually to directly fix it to the longitudinal beam 3 by bolt connection. However, there are many defects in the actual installation process. For example, when installing the bolts, the staff needs to hold the beam 1 continuously by hand. After all the beams 1 are installed, if the position needs to be changed, the bolts need to be removed, which is more troublesome. Therefore, the inventor has improved the existing installation method of the beam 1 and designed a new distribution cabinet beam 1, which is explained in detail below with reference to the drawings.

[0032] This embodiment provides a distribution cabinet crossbeam that is easy to install. Figure 1 The crossbeam 1 is installed in the main body 2 of the distribution cabinet. There are multiple crossbeams 1, and the position for installation can be selected according to the specific situation. Two longitudinal beams 3 are installed in the main body 2 of the distribution cabinet. The longitudinal beams 3 are located on both sides of the rear end surface of the main body 2 of the distribution cabinet and are used to fix the crossbeam 1. Moreover, multiple mounting beams 11 are installed on both sides of the main body 2 of the distribution cabinet. In this solution, four mounting beams 11 are provided, which are located on the outside of the upper and lower ends of the two longitudinal beams 3. The mounting beams 11 are fixed to the inner side surface of the main body 2 of the distribution cabinet, and the upper and lower ends of the two longitudinal beams 3 are fixed to the mounting beams 11. The longitudinal beams 3 can be fixed to the mounting beams 11 by bolt connection, and multiple crossbeams 1 are installed at intervals between the two longitudinal beams 3.

[0033] In this embodiment, combined with Figure 2-Figure 5, which is different from the existing method of directly fixing the crossbeam 1 and the longitudinal beam 3 by bolts, this solution adds a step before installing the bolts. The crossbeam 1 is fastened to the longitudinal beam 3 through other components, and the crossbeam 1 can be simply fixed first. In which, the two ends of the crossbeam 1 are equipped with mounting brackets 5 connected by connecting plates 4, that is, they are symmetrically installed at both ends of the crossbeam 1, and the mounting brackets 5 are set to U-shape. When installing the crossbeam 1, the U-shaped opening of the mounting bracket 5 faces the longitudinal beam 3 and abuts against the longitudinal beam 3, and the mounting brackets 5 are installed. The mounting frame 5 includes a panel 51, which is a vertical plate at the front end, and a horizontal plate 52 is connected to the upper and lower ends of the panel 51 near the longitudinal beam 3. The two horizontal plates 52 and the panel 51 form a U shape, and the horizontal plates 52 are in contact with the longitudinal beam 3, and a snap-fit ​​assembly 6 is provided on the plane where the horizontal plates 52 are in contact, that is, the two horizontal plates 52 are close to the end faces of the longitudinal beam 3, and a slot group 7 is provided on the longitudinal beam 3 for cooperating with the snap-fit ​​assembly 6, so that the crossbeam 1 can be snapped with the longitudinal beam 3 first along with the mounting frame 5.

[0034] After the mounting bracket 5 is buckled with the longitudinal beam 3, the mounting bracket 5 and the longitudinal beam 3 are fixed with the fastening bolts. Figure 2 , wherein the longitudinal beam 3 is provided with a plurality of threaded holes 8 at intervals from top to bottom, and a socket 9 is provided on the mounting frame 5, and the socket 9 is provided on the panel 51. The mounting frame 5 is fixed to the crossbeam 1 by passing the locking bolt 10 through the socket 9 and cooperating with the threaded hole 8. Different threaded holes 8 can be selected for fixing according to the actual installation position, and the socket 9 is located in the middle position of the two horizontal plates 52, that is, the two horizontal plates 52 are symmetrical with respect to the socket 9, so that when fixing the fastening bolt, it can be fixed in the middle position of the two horizontal plates 52, thereby improving balance and stability.

[0035] Specifically, the buckle assembly 6 includes two clamping blocks 61 provided on each horizontal plate 52, combined with Figure 4 and Figure 5 ,, that is, there are four blocks in total on the mounting bracket 5, and the block 61 is set to be L-shaped, and the cross section of the L-shape is horizontal, and the L-shaped opening directions of the two blocks 61 are consistent, and the openings of the blocks 61 connected to the horizontal plates 52 of the mounting bracket 5 at both ends of the beam 1 are consistent. Secondly, the slot group 7 includes two first slots 71 and two second slots 72 opened on the upper and lower sides of each threaded hole 8, that is, on the same side of the threaded hole 8, the first slot 71 and the second slot 72 are opened adjacent to each other for clamping the two blocks 61, and the lengths of the first slot 71 and the second slot 72 are consistent with the maximum length of the block 61, that is, when the mounting bracket 5 is buckled, the four mounting brackets 5 are inserted into the first slot 71 and the second slot 72 corresponding to the cross beam 1, and the cross beam 1 is slid toward the direction of the opening of the L-shaped block 61, so that the block 61 is clamped on the edges of the first slot 71 and the second slot 72.

[0036] Secondly, combined Figure 3 and Figure 4 , after the block 61 is matched with the first slot 71 and the second slot 72 respectively, the mounting frame 5 can be fixed to the longitudinal beam 3, and a limit block 62 is further provided on the horizontal plate 52 between the two blocks 61, and a limit slot 63 is provided on one side of the limit block 62, and the limit slot 63 is located on the side opposite to the opening direction of the limit block 62 and the block 61, and the slot group 7 also includes a third slot 73 connected to the first slot 71, located between the first slot 71 and the second slot 72, and the third slot 73 The width of the third slot 73 is greater than that of the first slot 71, that is, it extends outward relative to the first slot 71 in the width direction. The edge of the third slot 73 away from the threaded hole 8 is provided with a sloped protrusion 74 for contacting the limiting slot 63. The threaded hole 8 refers to the threaded hole 8 between the two first slots 71. When the beam 1 drives the mounting bracket 5 to slide, the limiting block 62 slides against the sloped protrusion 74, and after crossing the sloped protrusion 74, the limiting slot 63 adapts to the sloped protrusion 74 to fix the mounting bracket 5.

[0037] Moreover, the horizontal center line of the block 61 is collinear with the horizontal center line of the end face of the horizontal plate 52 on which it is located. Figure 5 The outer end surface of the limit block 62 is flush with the outer end surface of the horizontal plate 52 on which it is located, that is, it can ensure that the limit block 62 is located on the outside of the clamping block 61 and can be clamped with the sloped protrusion 74. In addition, a through groove 53 is provided on the horizontal plate 52, and the through groove 53 extends from the middle position of the horizontal plate 52 to the edge of the horizontal plate 52, and the through position is located between the limit block 62 and the clamping block 61. The purpose of setting the through groove 53 is twofold. On the one hand, when the limit block 62 abuts and moves with the sloped protrusion 74, the through groove 53 can provide the limit block 62 with a stable state. The displacement space enables it to cross the sloped protrusion 74. Secondly, when disassembling the mounting bracket 5, due to the larger width of the third slot 73, the through slot 53 of the horizontal plate 52 can be pressed. The flexible horizontal plate 52 can be deformed at this position, so that the limit slot 63 is separated from the sloped protrusion 74. Then, the mounting bracket 5 is slid in the direction opposite to the opening of the block 61, which can drive the longer side of the block 61 to move to a position aligned with the first slot 71 and the second slot 72. The mounting bracket 5 is pulled in the direction away from the longitudinal beam 3 to drive the crossbeam 1 to be disassembled.
