[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0042] like Figures 1 to 13 As shown, an embodiment of this application provides a chassis.

[0043] The following explanation uses a 19-inch standard chassis as an example.

[0044] The main parts of the 19-inch standard case assembled and welded include: upper cover plate, lower cover plate, two side plates, bracket and threaded fasteners, etc.

[0045] The upper cover plate and the lower cover plate have the same structure. The upper and lower cover plates are designed with a stepped structure and a third through hole at both ends, which are used to fix the two side plates during assembly. The upper and lower cover plates are designed with an elongated first hook-shaped structure and a threaded blind hole at one-third of the left and right positions, which are used to fix the bracket, as shown in the accompanying drawings. Figures 1 to 4 The bracket is designed with a second hook-shaped structure at the upper and lower ends, which is used to be buckled with the first hook-shaped structure of the upper and lower cover plates, and plays a limiting role. The bracket is designed with a first through hole at both ends in the length direction for screw positioning, and other parts can be designed in various shapes according to the needs of the equipment, as shown in the accompanying drawings. Figures 5 to 8

[0046] The first hook-shaped structure includes a first body, a first connecting part and a first hooking part 13; the first body is used to be installed to the upper cover plate or the lower cover plate; the first connecting part is connected with the first body and extends to the bracket direction; the first hooking part 13 is connected with one end of the first connecting part away from the first body, and a first groove is formed between the first hooking part 13, the first connecting part and the first body; the second hook-shaped structure includes a second body, a second connecting part 9 and a second hooking part 8; the second connecting part 9 is connected with the second body and extends away from the second body; the second hooking part 8 is connected with one end of the second connecting part 9 away from the second body, and a second groove is formed between the second hooking part 8, the second connecting part 9 and the second body; when the first hook-shaped structure and the second hook-shaped structure are buckled with each other, the first hooking part 13 is inserted into the second groove, and the second hooking part 8 is inserted into the first groove.

[0047] The second body includes a web plate 12, a wing plate 11 and a locking part 10, the top and bottom ends of the web plate are respectively provided with wing plates, each wing plate is provided with a locking part, and the locking part is provided with a second connecting part; the two ends of the locking part in the length direction respectively extend out of the wing plate, and the two ends of the locking part extending out are respectively provided with a first through hole 15; the upper cover plate and the lower cover plate are respectively provided with a threaded blind hole, and the second body is bolted to the blind hole of the upper cover plate or the lower cover plate through the screw passing through the first through hole.

[0048] ​The upper cover plate, the lower cover plate and the two side plates are assembled into the main frame of the case, and are fixed by locking screws. The two supports are inserted into the frame, the second hook structure on the upper and lower sides of the support is buckled with the first hook structure of the upper and lower cover plates, and the position of the support and the upper and lower cover plates is locked by the positioning screw to prevent displacement during transportation or welding. Finally, the joints between the upper and lower cover plates and the two side plates are welded. During the welding process and after the welding is completed and cooled, if the upper and lower cover plates are deformed outward, the second hook structure of the support can hook the first hook structure of the upper and lower cover plates to prevent deformation. If the upper and lower cover plates are deformed inward, the support will support the upper and lower cover plates to prevent the collapse of the upper and lower cover plates. At the same time, the joints of the upper and lower cover plates and the two side plates are reinforced by locking screws, which can also prevent deformation of the edges of the plates.

[0049] By the new structure design and assembly of the upper and lower cover plates and the support, the welding deformation problem of the 19-inch standard case is effectively solved.

[0050] According to one embodiment of the present application, the assembly and welding structure of the 19-inch standard case is composed of the following parts: 1 upper cover plate, lower cover plate, 2 two side plates, 3 support, 4 positioning screw, 5 locking screw, 6 front panel, 7 rear panel. First, the upper cover plate 1, the lower cover plate and the two side plates 2 are assembled into the main frame of the case, and are fixed by locking screws 5. The support 3 is inserted into the case frame, and the second hook structure on the upper and lower ends of the support 3 is buckled with the first hook structure on the upper cover plate 1 and the lower cover plate. The support 3 is positioned and fixed with the upper and lower cover plates 1 by the positioning screw 4. After the screws are tightened, the main frame of the case is welded and subsequent work is carried out, the front panel 6 and the rear panel 7 are installed and fixed to the main frame of the case by the locking screw 5, and the overall assembly of the case is completed. As shown in the assembly and welding structure diagram of the case provided by the present application. Figures 9 to 13 The assembly and welding structure diagram of the case provided by the present application is shown.

[0051] The beneficial effects of the present application are:

[0052] Through the structure design, two support parts are added, which greatly reduces the welding deformation of the 19-inch standard case, and further improves the manufacturing qualification rate of the case. The support part has a small volume and occupies a small space, but has a large buckling surface length with the upper and lower cover plates, which effectively prevents the deformation of the cover plates and reserves sufficient space for the installation of electrical materials in the case. The support part can be designed in various shapes to facilitate the installation of electrical materials. The support part is fixed by combining hook structure and blind hole, without through holes on the case, which ensures the waterproof sealing of the case. The assembly of the main frame of the case adopts a stepped structure 14, screw fastening and welding combination, which improves the three-proofing and electromagnetic shielding performance of the case. The present application can adapt to different U number and depth size of 19-inch cases, effectively controls the volume, weight and processing cost of the case while solving the deformation problem.

[0053] Of course, the present application is not only used for the 19-inch chassis, but also can be used for other size chassis, such as 15-inch, 13-inch, 17-inch, 16-inch, 20-inch, etc., which can all be applicable.

[0054] In the description of the present specification, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0055] Of course, the present application can also have other various embodiments, and those skilled in the art can make various corresponding changes and modifications according to the present application without departing from the spirit and essence of the present application, and these changes and modifications shall all belong to the protection scope of the claims of the present application.
