[0002] Some existing chassis, including the chassis body and the cover, have the cover positioned over the opening of the chassis body, with the side of the cover fixed to the side wall of the opening using bolts. While this installation method provides a secure connection between the cover and the chassis body, it makes disassembling and assembling the cover inconvenient. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a chassis that is easy to assemble and disassemble, making the disassembly and assembly of the chassis cover more convenient and simple.

[0004] According to an embodiment of the present invention, a chassis that is easy to assemble and disassemble includes a chassis body and a chassis cover. An opening is provided on one side of the chassis body, and at least two first snap-fit ​​edges are arranged around the periphery of the opening, with the two first snap-fit ​​edges arranged opposite each other. The chassis cover is placed over the opening, and the chassis cover has at least two second snap-fit ​​edges. All the second snap-fit ​​edges correspond one-to-one with all the first snap-fit ​​edges, and the second snap-fit ​​edges are attached to the outer or inner side of the corresponding first snap-fit ​​edges. One of the first snap-fit ​​edges and the second snap-fit ​​edges protrudes and is provided with a snap-fit ​​portion, while the other is provided with a snap-fit ​​groove. The first snap-fit ​​edge and the corresponding second snap-fit ​​edge are snap-fitted and fixed by the engagement between the snap-fit ​​portion and the snap-fit ​​groove. A rotating shaft is rotatably mounted on either the first or second snap-fit ​​edge, and a handle is connected to the rotating shaft. A first cam portion is provided on the outer periphery of the rotating shaft, and the first cam portion can abut against the second snap-fit ​​edge or the first snap-fit ​​edge. The handle is used to drive the first cam portion to rotate so that the first cam portion pushes the first snap-fit ​​edge away from the corresponding second snap-fit ​​edge.

[0005] The easily assembled and disassembled chassis according to the embodiments of this utility model has at least the following beneficial effects: When installing the chassis cover onto the chassis body, the cover is simply placed over the opening on the chassis body, allowing the first snap-fit ​​edge on the chassis body and the second snap-fit ​​edge on the cover to engage and be fixed through the snap-fit ​​part and the slot, eliminating the need for bolt connections and making installation more convenient. When disassembling the cover, the handle on the first or second snap-fit ​​edge can be rotated, causing the first cam on the rotating shaft to rotate. The first cam then pushes the first snap-fit ​​edge and the corresponding second snap-fit ​​edge apart, thereby releasing the snap-fit ​​relationship between the snap-fit ​​part and the slot, allowing the cover to be removed without needing to pry the first and second snap-fit ​​edges open with other tools. Therefore, the chassis provided by this utility model makes the assembly and disassembly of the cover more convenient and simple.

[0030] Reference Figure 1 , Figure 3 , Figure 5 and Figure 6 According to an embodiment of the present invention, a chassis that is easy to assemble and disassemble includes a chassis body 100 and a chassis cover 200. An opening 110 is provided on one side of the chassis body 100, and at least two first snap-fit ​​edges 110a are arranged around the periphery of the opening 110, wherein the two first snap-fit ​​edges 110a are arranged opposite to each other. The chassis cover 200 covers the opening 110, and the chassis cover 200 has at least two second snap-fit ​​edges 210. All the second snap-fit ​​edges 210 correspond one-to-one with all the first snap-fit ​​edges 110a, and the second snap-fit ​​edges 210 are attached to the outer side of the corresponding first snap-fit ​​edges 110a. One of the first snap-fit ​​edges 110a and the second snap-fit ​​edges 210 is provided with a snap-fit ​​part 111 and the other is provided with a snap-fit ​​groove 211. The first snap-fit ​​edge 110a and the corresponding second snap-fit ​​edge 210 are snap-fitted and fixed by the cooperation between the snap-fit ​​part 111 and the snap-fit ​​groove 211. A rotating shaft 310 is rotatably mounted on the first snap-fit ​​edge 110a or the second snap-fit ​​edge 210. The rotating shaft 310 is connected to a handle 320. A first cam part 330 is provided on the outer periphery of the rotating shaft 310. The first cam part 330 can abut against the second snap-fit ​​edge 210 or the first snap-fit ​​edge 110a. The handle 320 is used to drive the first cam part 330 to rotate so that the first cam part 330 pushes the first snap-fit ​​edge 110a and the corresponding second snap-fit ​​edge 210 apart.

[0031] It should be noted that in some other embodiments, the second card connector 210 may also be located inside the corresponding first card connector 110a.

[0032] The chassis provided by this utility model allows for easy installation of the cover 200 onto the chassis 100. Simply place the cover 200 over the opening 110 on the chassis 100, allowing the first snap-fit ​​edge 110a on the chassis 100 and the second snap-fit ​​edge 210 on the cover 200 to engage and secure themselves through the snap-fit ​​part 111 and the slot 211. This eliminates the need for bolt connections, making installation more convenient. When the cover 200 needs to be removed, the handle 320 on either the first snap-fit ​​edge 110a or the second snap-fit ​​edge 210 can be rotated. By rotating the first cam portion 330 on the rotating shaft 310 through the handle 320, the first cam portion 330 pushes the first snap-fit ​​edge 110a and the corresponding second snap-fit ​​edge 210 apart, thereby releasing the snap-fit ​​relationship between the snap-fit ​​part 111 and the slot 211, and thus the cover 200 can be removed without using other tools to pry open the first snap-fit ​​edge 110a and the second snap-fit ​​edge 210, making disassembly convenient. Therefore, the chassis provided by this utility model makes the disassembly and assembly of the cover 200 more convenient and simple.

[0033] Reference Figures 2 to 4 According to some embodiments of this utility model, the rotating shaft 310 is rotatably mounted on the corresponding first snap-fit ​​edge 110a and located inside the corresponding first snap-fit ​​edge 110a. The rotating shaft 310 is provided with a plurality of first cam portions 330 spaced apart along the axial direction. The first snap-fit ​​edge 110a is provided with a first clearance hole 112 for the handle 320 to pass through and a second clearance hole 113 for the first cam portions 330 to pass through. The second snap-fit ​​edge 210 is provided with a third clearance hole 212 for avoiding the handle 320. With the above arrangement, the length of the rotating shaft 310 can be similar to the length of the first snap-fit ​​edge 110a, so that the first cam portion 330 can be arranged next to each snap-fit ​​portion 111, thereby better releasing the snap-fit ​​relationship between all snap-fit ​​portions 111 and the corresponding slots 211. At the same time, the rotating shaft 310 can be hidden inside the housing 100. In addition, during the process of placing the lid 200 on the opening 110 of the box body 100, while the second locking edge 210 is engaged with the first locking edge 110a, the second locking edge 210 can also push the first cam part 330 to rotate, so that the first cam part 330 automatically returns to the position where the second locking edge 210 is not pushed open.

[0034] According to some embodiments of the present invention, each snap-fit ​​part 111 is located between two corresponding first cam parts 330. Thus, during the disassembly of the box cover 200, the handle 320 can more smoothly disengage the corresponding snap-fit ​​part 111 from the corresponding slot 211 through the two adjacent first cam parts 330.

[0035] Reference Figure 3 and Figure 4 According to some embodiments of this utility model, in each rotating shaft 310, a second cam portion 340 is provided on the outer periphery of the rotating shaft 310. The protruding direction of the second cam portion 340 is arranged at a right angle to the protruding direction of the first cam portion 330. The second cam portion 340 passes through the corresponding second clearance hole 113. The second locking edge 210 has a locking groove 213 for the second cam portion 340 to be inserted. When the first cam portion 330 pushes the first locking edge 110a away from the corresponding second locking edge 210, the second cam portion 340 disengages from the corresponding locking groove 213. A safety lock is provided between the housing 100 and the handle 320 to lock the handle 320 onto the housing 100. With the above configuration, during the process of installing the lid 200 into the opening 110 of the box body 100, while the second locking edge 210 is engaged with the first locking edge 110a, the second locking edge 210 can also push the first cam part 330 to rotate, so that the first cam part 330 automatically returns to the position where the second locking edge 210 is not pushed open, and the second cam part 340 automatically rotates into the locking groove 213. After the handle 320 is locked by the safety lock, the second cam part 340 can engage with the side wall of the locking groove 213, thereby preventing the lid 200 from being pried open by others and playing an anti-theft role.

[0036] Reference Figures 5 to 7 In other embodiments, the rotating shaft 310 can also be rotatably mounted on the outer side of the corresponding second snap-fit ​​edge 210. The second snap-fit ​​edge 210 has a third clearance hole 212. The first cam portion 330 is located in the third clearance hole 212 and abuts against the corresponding first snap-fit ​​edge 110a. Thus, by rotating the handle 320, the first cam portion 330 can be rotated, pushing the first snap-fit ​​edge 110a towards the inside of the housing 100. The second snap-fit ​​edge 210 is pushed outward under the reaction force, thereby separating the first snap-fit ​​edge 110a from the corresponding second snap-fit ​​edge 210. Subsequently, the lid 200 can be removed from the housing 100 by pulling the handle 320, making the removal and installation of the lid 200 more convenient and simple. A safety lock is provided between the housing 100 and the handle 320 to lock the handle 320 onto the housing 100. Therefore, once the safety lock locks the handle 320, it can directly prevent the lid 200 from separating from the body 100, thus achieving the anti-theft function.

[0037] According to some embodiments of this utility model, the box body 100 is a sheet metal part and the box cover 200 is a sheet metal part. Therefore, the first snap-fit ​​edge 110a, the second snap-fit ​​edge 210, the snap-fit ​​part 111, etc. can all be formed by stamping, which is convenient and simple to process.

[0038] Reference Figure 1 and Figure 5According to some embodiments of the present invention, the housing 100 is provided with heat dissipation holes to dissipate heat from other electrical components installed inside the housing 100.

[0039] Reference Figure 1 and Figure 5 According to some embodiments of the present invention, it also includes a louver 400, which covers the heat dissipation hole, changes the direction of the airflow, and prevents large objects from entering the housing 100 through the heat dissipation hole.

[0040] According to some embodiments of the present invention, the louver 400 is snapped onto the side wall of the heat dissipation hole by an elastic buckle, thereby making the louver 400 easy to install and remove, which facilitates the later installation, removal and cleaning of the louver 400.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
