Description

Technical Field

[0001] The invention relates to a profile, in particular to a frame profile for a cabinet. Background Art

[0002] The cabinets produced in the railway signal field are generally made of cold-rolled steel plates or aluminum alloys to store control equipment such as signals and communications, which can provide protection for the stored equipment and electromagnetic shielding interference. Arrange the equipment in an orderly and neat manner to facilitate future equipment maintenance. In the prior art, in order to meet the use requirements, the cabinet with a frame structure uses 12 profiles that are welded together to form a frame. This method has the following disadvantages: 1. The basic dimensional accuracy of the inner width of the frame is high, which is the key dimension to ensure the subsequent installation of electrical equipment, and welding is easy to deform; 2. The assembled cabinet is difficult to transport due to its large size, and the space utilization rate is low. If it is damaged during transportation, it needs to be replaced as a whole, resulting in a waste of resources; 3. In order to increase the torsional strength of the profile, a large amount of welding is required, and welding will produce a large amount of exhaust gas, and the subsequent processing process will produce a large amount of dust, which will cause great pollution to the environment.

The strength bending unit consists of a first limiting edge for supporting the other side of the steel plate and a strength bending edge supported on the inner edge of the inner cavity. The first limiting edge and the strength bending edge form an angle.

[0006] Furthermore, the first limiting edge and the strength bending edge are perpendicular.

DETAILED DESCRIPTION

[0025] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0026] A cabinet frame profile, made of bent steel plates, such as Figure 1-3 As shown, the cross section of its outer frame is a closed frame, one side of the steel plate enters the inner cavity of the profile from the joint with the other side to form a strength bending unit, the strength bending unit is composed of a first limiting edge 4 for supporting the other side of the steel plate and a strength bending edge 12 supported on the inner edge of the inner cavity, the first limiting edge 4 and the strength bending edge 12 form an angle, therefore, the first limiting edge 4 forms a cavity on both sides, in this embodiment, the first limiting edge 4 and the strength bending edge 12 are perpendicular, so that there can be a stronger structural strength. The deformation caused by welding is reduced, and the longitudinal structural strength of the cabinet made of the profile can be improved by the design of the first limiting edge and the strength bending edge. It can not only ensure that the profile has good anti-twisting and overall strength, but also enable the profile to achieve IP-level sealing and have good waterproof and dustproof performance. Even if the cabinet assembled by this profile is used in extremely poor environment, it can provide good protection for computers and other equipment installed inside the cabinet.

[0027] The cross section of the outer frame of the profile includes an inner supporting portion and an outer supporting portion, and a second limiting edge 6 and a third limiting edge 10 connecting the inner supporting portion and the outer supporting portion.

[0028] One side of the steel plate is located in the outer support portion from the splice with the other side.

[0029] The inner support portion includes a third inner bending edge 7, a second inner bending edge 8 and a first inner bending edge 9 connected in sequence. The outer frame is provided with mounting holes on the side surfaces corresponding to the third inner bending edge 7, the second inner bending edge 8 and the first inner bending edge 9. Figure 1 As shown, the second inner bending edge 8 is perpendicular to the third inner bending edge 7 and the first inner bending edge 9. Figure 2In the structure shown, the second inner bending edge 8 and the third inner bending edge 7 form an angle that is not a right angle with the first inner bending edge 9. The second inner bending edge is used for tightening the locking rod on the door panel to ensure the sealing of the cabinet. In addition, the strength bending edge 12 and the third inner bending edge 7 are closely arranged and connected.

[0030] The outer support part includes a second sealing edge 11, a first outer bending edge 1, a first sealing edge 2, a second outer bending edge 3 and a third outer bending edge 5 which are arranged in sequence. The third outer bending edge 5 is connected to the third inner bending edge 7 through a second limiting edge 6. The second sealing edge 11 is connected to the first inner bending edge 9 through a third limiting edge 10. The second sealing edge 11, the first outer bending edge 1, the first sealing edge 2 and the second outer bending edge 3 are connected in sequence, and the second outer bending edge 3 is connected to the first limiting edge 4. The outer frame is provided with mounting holes on the side surfaces corresponding to the first outer bending edge 1, the second outer bending edge 3 and the third outer bending edge 5. The mounting holes at the two ends are used for screws or pins to pass through to connect the profiles to assemble and position them into a cabinet frame, and the mounting holes between the two ends are used to install external accessories of the cabinet.

[0031] The first outer bending edge 1, the first sealing edge 11 and the second sealing edge 2 are used for pasting the EMC sealing strip.

[0032] The mounting holes include special-shaped holes 13 and round holes 14. The special-shaped holes 13 are arranged at equal intervals along the length direction of the profile. Specifically, the special-shaped holes 13 are opened on the third inner bending edge.

[0033] The included angle between the first outer bending edge 1 and the first inner bending edge 9 is 45 degrees.

[0034] The first inner bending edge 9 and the second outer bending edge 3 are parallel, and the third inner bending edge 7 and the third outer bending edge 5 are parallel to each other.

[0035] The mounting holes opened at the two ends of the first outer bending edge of the profile facing the outside of the cabinet can be used to connect the profiles by screwing, riveting, etc. to assemble and position them into a cabinet frame. Compared with the traditional welding method, the assembly is simple and convenient, which greatly improves the efficiency in transportation, installation, production, warehousing, etc., realizes the rational utilization and allocation of resources, and saves resources and reduces pollution to the environment; opening multiple mounting holes on the outer bending edge can facilitate the assembly of the profile and the installation and fixing of door panels, side panels and other external cabinet related accessories. The mounting holes opened in a certain sequence on the inner bending edge can freely and flexibly expand the installation equipment inside the cabinet.

[0036] Combination Figure 3As shown, the internal equipment of the cabinet includes equipment that needs protection, such as computers, controllers, and internal brackets for supporting these equipment. The special-shaped holes 13 and the round holes 14 are provided on the third inner bending edge 7 for identification, which facilitates identification of the installation position when installing the internal equipment. The installation holes make the installation and expansion of the internal equipment more flexible and convenient.

[0037] Combination Figure 4 As shown, the frame profile can ensure that the profile has good anti-distortion and overall strength, and also enable the profile to achieve IP-level sealing, with good waterproof and dustproof performance. Even if the cabinet assembled from such profile is used in extremely bad environments, it can provide good protection for computers and other equipment installed inside the cabinet. After testing, the strength of the cabinet frame made of the profile provided in this embodiment can be increased by more than 30%.
