Description

Technical Field

[0001] This utility model relates to the field of communication engineering technology, specifically to a communication engineering cabinet. Background Technology

[0002] A communication engineering cabinet is a device used to store electrical components. Cabinets are generally made of cold-rolled steel plates or alloys and are used to store computers and related control equipment. They can provide protection for the stored equipment, shield electromagnetic interference, arrange the equipment in an orderly and neat manner, and facilitate future equipment maintenance.

[0003] Existing communication engineering cabinets are usually rectangular, which makes it easy to neatly arrange and install electrical components. However, as the number of devices increases, the cabinet space may become insufficient. The existing cabinet structure is fixed, and multiple side walls are fixed together by bolts or welding, which cannot expand the internal space and makes later maintenance inconvenient.

[0004] To address the aforementioned technical problems, this application proposes a space-expandable communication engineering cabinet. Utility Model Content

[0009] The extended cabinet includes two extended panels, a set of side panels, and two connecting panels. The two extended panels are rotatably installed on the front and rear sides of the side wall of the main cabinet without panels. The two sets of extended panels are spliced ​​together to form the side wall panel of the main cabinet. A side panel is connected between the two sets of extended panels on the side away from the main cabinet. The two connecting panels are rotatably installed on the upper and lower side walls of the main cabinet and are respectively connected to the upper and lower sides of the two sets of extended panels.

[0010] As an improvement, one set of the expansion plates has a limiting protrusion on the side away from the main cabinet, and the other set of the expansion plates has a strip-shaped slot on the side away from the main cabinet to engage with the limiting protrusion.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] When the internal space of the main cabinet 1 is insufficient, it is necessary to expand the installation space for more electrical components, as shown in the attached document. Figure 1 and attached Figure 5 As shown, a communication engineering cabinet includes a main cabinet 1. The front side wall and the adjacent side wall of the main cabinet 1 are both plateless structures. A cabinet door is installed on the front side wall of the main cabinet 1. An extension cabinet is installed on one side wall of the main cabinet 1. The extension cabinet includes two extension plates 4, a set of side plates 5, and two connecting plates 6. The two extension plates 4 are rotatably installed on the front and rear parts of the plateless side wall of the main cabinet 1. The two connecting plates 6 are rotatably installed on the upper and lower side walls of the main cabinet 1, respectively. When the two extension plates 4 are unfolded, they are on the same plane as the front and rear side walls of the main cabinet 1. The upper and lower sets of connecting plates 6 rotate to the upper and lower sides of the two extension plates 4 and contact the two extension plates 4. The outer edges of the connecting plates 6 are provided with grooves 14. Bolts 11 pass through the bottom of the grooves 14 to fix the connecting plates 6 to the lower side of the extension plates 4.

[0027] As attached Figure 4 As shown, a side plate 5 is connected between the two sets of expansion plates 4 on the side away from the main cabinet 1. A limiting connecting plate 12 is integrally formed at both edges of the side plate 5. The limiting connecting plate 12 is attached to the outer wall of the side of the expansion plate 4 away from the main cabinet 1 and is connected by multiple sets of bolts 13. The connected expansion plate 4, side plate 5 and connecting plate 6 form an expansion cabinet that is connected to the main cabinet 1, expanding the installation space for more electrical components.

[0028] As attached Figure 1As shown, support plates 2 are installed on the front and rear sides of the main cabinet 1, and multiple sets of support legs 3 are installed on the lower side of the support plates 2. The support plates 2 are located outside the connecting plate 6 and extend towards the side plate 5. After the extended cabinet is installed, the support plates 2 and multiple sets of support legs 3 play a role in providing stable support.

[0029] Example 2

[0030] Based on Example 1, when the extended cabinet is retracted without expanding the internal space of the main cabinet 1, as shown in the attached... Figure 2 and attached Figure 3 As shown, the two sets of expansion plates 4 are spliced ​​together to form the side wall panel of the main cabinet 1. A U-shaped limiting strip 7 is installed on the outside of the expansion plate 4. The side panel 5 is provided with two sets of U-shaped slots 8 on the side away from the limiting connecting plate 12, which are inserted into the U-shaped limiting strip 7. After the two expansion plates 4 come into contact with the main cabinet 1, the side panel 5 moves to the upper side of the two expansion plates 4, and the lower end of the U-shaped slot 8 corresponds to the upper end of the U-shaped limiting strip 7. The side panel 5 moves downward and the U-shaped limiting strip 7 is inserted into the U-shaped slot 8. A baffle is provided at the bottom of the U-shaped limiting strip 7 to support the lower side of the side panel 5. The two sets of expansion plates 4 are connected through the side panel 5.

[0031] One set of expansion plates 4 has a limiting protrusion 10 on the side away from the main cabinet 1, and the other set of expansion plates 4 has a strip groove 9 that engages with the limiting protrusion 10 on the side away from the main cabinet 1. The strip groove 9 into which the limiting protrusion 10 engages ensures that there is no gap between the two sets of expansion plates 4.

[0032] As attached Figure 2 and attached Figure 4 As shown, a magnet 15 is embedded in the outer wall of the connecting plate 6, and magnets 16 that attract magnets 15 are embedded in the upper and lower outer walls of the main cabinet 1. When the main cabinet 1 is lifted up, the two connecting plates 6 are rotated to the upper and lower sides of the main cabinet 1 respectively. The two connecting plates 6 are fixed to the upper and lower sides of the main cabinet 1 by the attraction between magnets 15 and magnets 16.
