[0031] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0032] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the referred module or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0034] Embodiment 1

[0035] Refer to Figures 1-3 , the present utility model provides a plug-in support chassis 1, which is formed by plugging two chassis units 11 with exactly the same structure from left to right. Specifically, the chassis unit 11 is of a semi-circular structure, and a semi-circular and through notch 111 is provided in the middle of the chassis unit 11. A card slot 112 is provided at the top of the chassis unit 11, which surrounds the notch 111 and is communicated with the notch 111. Thus, when assembly is required, the card slot 112 of one chassis unit 11 can be first clamped on one side of the bottom of the fan, and then the card slot 112 of the other chassis unit 11 is clamped on the other side of the bottom of the fan until the two chassis units 11 are plugged and fixed from left to right. The two chassis units 11 are spliced to form the support chassis 1 to limit and support the bottom of the fan.

[0036] Among them, a first clamping structure is provided on the chassis unit 11. When the two chassis units 11 are plugged from left to right, the plug-in fixation can be achieved through the clamping cooperation of the two first clamping structures. Specifically, the first clamping structure includes a card hole 1142 and a card block 1141 arranged at intervals before and after on the chassis unit 11. When the two chassis units 11 are plugged from left to right until the card block 1141 on one chassis unit 11 is clamped with the card hole 1142 on the other chassis unit 11, and the card hole 1142 on one chassis unit 11 is clamped with the card block 1141 on the other chassis unit 11, the two chassis units 11 are plugged and fixed from left to right.

[0037] Preferably, the clamping block 1141 is an elastic clamping block, and an abutting inclined surface 11411 is provided on the elastic clamping block. When the elastic clamping block on one chassis unit 11 is butted against the clamping hole 1142 on another chassis unit 11, the abutting inclined surface 11411 on the elastic clamping block abuts against the clamping hole 1142 and causes the elastic clamping block to rotate and partially extend into the clamping hole 1142. When the abutting inclined surface 11411 is separated from the clamping hole 1142, the elastic clamping block resets and completely snaps into the clamping hole 1142, and at this time, the two are clamped and fixed.

[0038] Thus, when it is necessary to perform butt joint assembly on the two chassis units 11, one chassis unit 11 can be first clamped on one side of the bottom of the fan, and then another chassis unit 11 is clamped on the other side of the bottom of the fan until the two are butted and fixed left and right. At this time, the two chassis units 11 are spliced into the support chassis 1. Therefore, by adopting the above-mentioned structure of the chassis unit 11, not only can the two chassis units 11 be respectively assembled on the fan, but also during assembly, only butt joint left and right until the two first clamping structures are clamped with each other to complete the splicing. The assembly method is simple, and after the assembly is completed, it can be assembled with the fan without further assembly and fixation with the fan, thereby reducing the assembly steps and greatly improving the assembly efficiency.

[0039] Refer to Figures 1-3 again, a first avoidance hole 117 communicating with the card slot 112 and for the fan power cord to pass through, a third avoidance hole 119 opened at the edge of the chassis unit 11, and a second avoidance hole 118 opened on the chassis unit 11 and located between the first avoidance hole 117 and the third avoidance hole 119 are also provided on the chassis unit 11.

[0040] Thus, the fan power cord can pass through the first avoidance hole 117, the second avoidance hole 118, and the third avoidance hole 119 in sequence and extend out, making the wiring layout of the power cord more reasonable, thereby avoiding phenomena such as entanglement.

[0041] Furthermore, the fan further includes a first strengthening groove 115 opened at the bottom of the chassis unit 11 and wound around the outer circumference of the card slot 112. A plurality of first strengthening ribs 1151 are arranged at intervals along the circumferential direction in the first strengthening groove 115. In addition, a second strengthening groove 116 opened at the bottom of the chassis unit 11 and wound around the outer circumference of the first strengthening groove 115 is also included. A plurality of second strengthening ribs 1161 are arranged at intervals along the circumferential direction in the second strengthening groove 116.

[0042] Thus, by providing a first reinforcing groove 115 and a second reinforcing groove 116 on the chassis unit 11, the weight of the chassis unit 11 is reduced, making it more convenient for transportation. At the same time, the amount of material is reduced, and the cost is lowered. Additionally, by providing a plurality of first reinforcing ribs 1151 in the first reinforcing groove 115 and a plurality of second reinforcing ribs 1161 in the second reinforcing groove 116, it is possible to ensure the support strength of the chassis unit 11 while reducing the amount of material, thereby extending its service life.

[0043] Embodiment 2

[0044] Refer to Figures 4-7 , in addition, the present utility model further provides a fan, which includes the plug-in support chassis 1 of the above-mentioned Embodiment 1, a body (not shown in the figure), and a bottom cover 2 provided at the bottom of the body. The two chassis units 11 are plugged and fixed to each other left and right and are clamped on the outer periphery and bottom of the bottom cover 2 to achieve limit support.

[0045] In this embodiment, the fan is a heater; of course, in other embodiments, it may also be other types of fans such as an electric fan or a tower fan, and there is no limitation here.

[0046] Wherein, a second clamping structure is further provided between the chassis unit 11 and the bottom cover 2 to achieve clamping and fixing. The second clamping structure includes a clamping post 21 provided on the side of the bottom cover 2 and a clamping post cavity 113 provided on the chassis unit 11 and having a shape adapted to that of the clamping post 21. When the two chassis units 11 are spliced and fixed left and right, the clamping post 21 is inserted into the clamping post cavity 113 to achieve limit fixation between the two.

[0047] It should be noted that in other embodiments, the positions of the clamping post 21 and the clamping post cavity 113 can also be interchanged, and the same technical effect can be achieved, and there is no limitation here.

[0048] In this embodiment, four clamping posts 21 are provided and are respectively arranged at the four corners of the chassis unit 11, and the number and arrangement positions of the clamping post cavities 113 correspond to those of the clamping posts 21.

[0049] In summary, for the plug-in support chassis 1 provided by the present utility model and the fan having the same, by adopting the above-mentioned chassis unit 11, the two chassis units 11 can be respectively installed on the fan, and during assembly, it is only necessary to plug them left and right until the two first clamping structures are clamped with each other to complete the splicing. The assembly method is simple, and after the assembly is completed, the assembly with the fan can be achieved, and there is no need to perform further assembly and fixation with the fan, thereby reducing the assembly steps and greatly improving the assembly efficiency.

[0050] It should be understood that the orientation or positional relationship indicated by terms such as "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the referred module or element must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0051] In addition, in the description of the present utility model, the meanings of "a plurality of" and "several" are two or more, unless otherwise specifically and clearly defined.

[0052] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present utility model.
