[0030] like Figures 1-2As shown, in the existing shell assembly structure, the back cover 1 is installed on the shell 2. A front buckle 12 or a front slot is provided on the front side of the back cover 1, and a corresponding front slot 22 or a front buckle is provided on the shell 2. A first screw hole is provided on the rear side of the back cover 1, and a corresponding screw hole is also provided on the upper part of the rear plate. When it is necessary to assemble the back cover onto the shell 2, the back cover is first assembled parallel to the shell 2, and then the back cover is fixed with screws. This assembly structure only fixes the front and rear sides of the back cover 1, which makes the left and right sides of the back cover easy to loosen or even warp, affecting the assembly efficiency.

[0031] like Figures 3-5 As shown, a shell assembly structure includes a rear cover 1 and a shell 2. The rear cover 1 is mounted on the shell 2. A front buckle 12 is provided on the front side of the rear cover 1, and a corresponding front slot 22 is provided on the shell 2. The front side of the rear cover 1 is connected to the front slot 22 through the front buckle 12. A first screw hole 111 is provided on the rear side of the rear cover 1, and a corresponding screw hole is also provided on the upper part of the rear plate. A side buckle 13 or a side slot is provided on the side of the rear cover 1, and a side slot 23 or a side buckle is provided at the corresponding part of the shell 2. Thus, the front and rear sides, as well as the left and right sides of the rear cover 1 are all fixedly connected to the shell 2, realizing the all-round fixed installation of the rear cover 1, preventing local warping of the edges of the rear cover 1, and avoiding deformation of the rear cover 1.

[0032] The outer casing 2 has a mounting part on its top, and the rear cover 1 is mounted on this mounting part to seal and fix the top of the outer casing 2. Specifically, taking the outer casing 2 with a slot and the rear cover with a buckle as an example, a front slot 22 is provided near the front edge of the mounting part of the outer casing 2. The front slot 22 is a slot hole structure. A front buckle 12 is provided on the front side of the rear cover 1. The front buckle 12 is a forward-protruding structure. The front buckle 12 extends into the front slot 22 to fix and support the front of the rear cover 1.

[0033] As part of the embodiment of this utility model, the front buckle 12 and the front slot 22 are both set on both sides, and the two front buckles 12 are set on the front side of the rear cover 1 and close to both ends.

[0034] Furthermore, the front buckle 12 includes a first extension plate 121, a first connecting plate 122, and a second extension plate 123. The first extension plate 121 is connected to the main body of the rear cover 1 and is flush with the upper and lower surfaces of the main body of the rear cover 1. The first extension plate 121 extends forward. The first connecting plate 122 is connected to the side of the first extension plate 121 away from the main body of the rear cover 1. The first connecting plate 122 extends downward. The second extension plate 123 is provided on the side of the first connecting plate 122 away from the first extension plate 121. The second extension plate 123 extends forward. The arrangement of the first extension plate 121, the first connecting plate 122, and the second extension plate 123 makes the front buckle 12 form a Z-shaped structure. When the rear cover 1 is fixedly connected to the outer shell 2, the second extension plate 123 of the rear cover 1 extends into the front slot 22, and the second extension plate 123 is located at the lower part of the rear cover 1, thereby limiting and fixing the front side of the rear cover 1.

[0035] Side buckles 13 are provided on both sides of the back cover 1. The side buckles 13 include a side connecting plate 131 and a locking plate 132. The side connecting plate 131 is connected to the side edge of the back cover 1 and extends away from the body of the back cover 1. A locking plate 132 is provided at the end of the side connecting plate 131 and extends downward, so that the side buckles 13 form a hook structure. When installed, the hook is hooked into the side slot 23 of the outer shell 2, which facilitates the installation and fixation of the back cover 1.

[0036] Furthermore, there are two side buckles 13, located on the left and right sides of the back cover 1 respectively. The side buckles 13 are located on the side of the back cover 1 near the front. The side slots 23 are also located on the side of the mounting part near the front. Overall, it is convenient to fix the two corners of the back cover 1 near the front.

[0037] Furthermore, the width of the retaining plate 132 in the front-to-back direction is greater than the width of the side connecting plate 131 in the front-to-back direction, and one side of the side connecting plate 131 is flush with the retaining plate 132, so that a gap 133 is formed between the side connecting plate 131 and the retaining plate 132. When the two sides of the rear cover 1 are connected to the outer shell 2, the retaining plate 132 first extends into the side retaining groove 23 to limit the left and right sides of the rear cover 1, and then pushes the rear cover 1 backward so that the front side of the side connecting plate 131 abuts against the front edge of the side retaining groove 23, thereby making the rear cover 1 snap into place. Preferably, the side retaining groove 23 is designed with a structure that is narrow at the front and wide at the back to prevent the rear cover 1 from shaking significantly in the left and right direction after it is installed.

[0038] As one embodiment of the present invention, a slot can also be provided on the back cover and a slot can also be provided on the outer shell, as long as the corresponding parts of the two can be connected.

[0039] In this embodiment, after the front and left and right sides of the rear cover 1 are all snapped into place, the first screw hole 111 on the rear side of the rear cover 1 is precisely aligned with the corresponding screw hole on the rear plate 5. The connector 3 passes through the two screw holes to fix the rear side of the rear cover 1 to the rear plate 5. Furthermore, a rear flange 11 is provided on the rear side of the rear cover 1. The rear flange 11 is configured to extend downwards, and the first screw hole 111 is provided on the rear flange 11, so that the connector is fixed in a backward-forward direction, which saves space compared to fixing the connector from top to bottom.

[0040] The first screw hole 111 is located on the rear side of the rear cover 1, and there are two first screw holes 111, located near the left and right ends respectively. This allows the first screw hole 111 to cooperate with the front buckle 12 to fix the four corners of the rear cover 1, preventing the edges of the rear cover 1 from warping.

[0041] When the back cover 1 needs to be installed on the outer shell 2, first align the side buckles 13 on both sides of the back cover 1 with the two side slots 23 on the outer shell 2, and align the front buckle 12 of the back cover 1 with the front slot 22 of the outer shell 2. Then, insert the side buckles 13 downward into the side slots 23 so that the back cover 1 is installed in the height direction. Then push the back cover 1 forward so that the front buckle 12 of the back cover 1 engages with the front slot 22 of the outer shell 2, and the front side of the side connecting plate 131 of the side buckle 13 abuts against the front edge of the side slot. At this time, the back cover 1 is snapped into place, and the front and left and right sides of the back cover 1 are fixed. Then, use the connector 3 to pass through the first screw hole 111 and the screw hole on the back plate 5 to fix the rear side of the back cover 1. Therefore, one component has a limiting buckle, and the other has a limiting groove. During assembly, the buckle passes under the groove to limit the movement. After the buckle is assembled to a certain distance, it is confined within the groove structure, preventing the assembled back cover from falling off freely. It is then secured with screws. Assembly can be done directly according to the assembly diagram, requiring no additional handling or placement by the user. The buckle-groove assembly method ensures accurate positioning and a simple structure, making the back cover more stable and reliable as it is directly assembled onto the outer shell. Furthermore, this structure, composed of two components, ensures reliability through manufacturing process dimensions, allowing for convenient and quick assembly, significantly improving assembly speed while reducing overall machine throughput.

[0042] As part of the embodiments of this utility model, a microwave oven is also provided, including the outer shell assembly structure described above, and a door 4 is provided on the front side of the outer shell, the door 4 being used to seal the cooking cavity of the microwave oven.

[0043] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
