The left and right sides of the front casing are respectively connected and fixed to the front bending plates on the left casing and the front bending plates on the right casing by screws. The left and right sides of the rear casing are respectively connected and fixed to the rear bending plates on the left casing and the rear bending plates on the right casing by screws.

[0006] In one or more embodiments, the front bending plate is attached to the front casing, and the rear bending plate is attached to the rear casing.

[0007] In one or more embodiments, the casing structure further includes a bottom plate, and the bottom plate is respectively snap-connected and fixed to the left casing and the right casing.

[0008] In one or more embodiments, snap positions are provided on the inner sides of the left casing and the right casing, and hooks that cooperate with the snap positions for snap connection are provided on the bottom plate.

[0009] In one or more embodiments, the rear casing includes a first casing and a second casing distributed up and down. The second casing has a first plate body and a second plate body that are perpendicular to each other. The second plate body is connected and fixed to the first casing by screws, and the outer edge of the first plate body abuts against the inner side surfaces of the left casing and the right casing.

[0010] In one or more embodiments, the bottom of the front casing is connected and fixed to the bottom plate by screws.

[0011] The effects of the present utility model compared with the background technology are as follows: The casing of the cylindrical machine is divided into multiple parts and spliced together, enabling the appearance of the cylindrical machine to be diverse, greatly enhancing the appearance. Moreover, during the initial assembly, it is not restricted by the internal space, which is conducive to improving production efficiency and facilitating later disassembly and maintenance.

Detailed Embodiment

[0015] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model. However, it should not be construed as a limitation on the protection scope of the present utility model.

[0016] Refer to the attached Figures 1-3 , this application provides a casing structure of a cylindrical machine, which includes a left casing 1, a front casing 2, a right casing 3 and a rear casing. Front bending plates 4 are provided on the front sides of the left casing and the right casing, and rear bending plates 5 are provided on the rear sides of the left casing and the right casing. The left and right sides of the front casing 2 are respectively connected and fixed to the front bending plates on the left casing 1 and the front bending plates on the right casing 3 by screws. The left and right sides of the rear casing are respectively connected and fixed to the rear bending plates on the left casing 1 and the rear bending plates on the right casing 3 by screws. For the cylindrical machine adopting the above structure, its appearance can be diversified, different-shaped cylindrical machines can be designed, and a suitable internal space can be obtained for installing main components such as motors, volute casings, and fan blades. At the same time, when assembling the internal structure, the left casing, the front casing, and the right casing can be assembled first, then the internal structure components can be installed, and finally the rear casing can be installed.

[0017] The front bending plate 4 is attached to the front casing 2, and the rear bending plate 5 is attached to the rear casing, which helps to enhance the structural stability of the assembled left casing, front casing, right casing and rear casing and is not prone to deformation.

[0018] The housing structure further includes a bottom plate 6, which is fixedly clamped to the left housing 1 and the right housing 3 respectively. Installing the bottom plate in a clamping manner can save screw installation, has the advantages of easy installation and disassembly, and the bottom plate can enhance the structural stability of the bottom of the housing. Preferably, clamping positions 7 are provided on the inner sides of the left housing 1 and the right housing 3, and hooks 8 that cooperate with the clamping positions for clamping are provided on the bottom plate.
