Description

Technical Field

[0001] This utility model relates to the field of pet supplies, specifically to a quick-release structure for a food stirring fan blade. Background Technology

[0002] The food agitator blades are installed in the food container of a pet feeder to rotate and agitate the food as it is dispensed, preventing it from pooling in one place. Currently, there are various methods for fixing the food agitator blades, mainly divided into fixed connections and detachable connections.

[0003] Fixed connections typically use methods such as adhesive application or hot-melt welding, which are not conducive to later disassembly and assembly. Detachable connections typically use screws for fixing, with the grain stirring fan blades relying on screws to fix the grain hopper and rotating shaft bracket together. However, this method is not conducive to disassembly and assembly, and tools are needed to remove the screws.

[0004] Alternatively, detachable connections can also use a snap-fit ​​method, with snap-fits on both sides of the grain agitator blades. The rotating shaft bracket can be pushed upwards until it reaches a certain position, at which point the grain agitator blades are ejected. However, in this snap-fit ​​connection method, the main body of the grain agitator blades is split into two parts, the rotating shaft bracket is inserted into the two parts, and then the two parts are fixed together with screws. This connection method has many structural components, which makes it difficult to manufacture and results in higher component costs. Utility Model Content

[0013] The quick-release structure of the grain stirring fan blade provided by this utility model may also have the following feature: when the main body is connected to the fan blade body, the connecting hook is engaged above the elastic extension protrusion.

[0014] The beneficial effects of this utility model are as follows: The quick-release structure of the grain-stirring fan blade of this utility model includes a main body, a rotating shaft support, and a fan blade main body. The fan blade main body is sleeved on the outside of the rotating shaft support, and after being connected to the rotating shaft support, it is detachably connected to the main body. The main body has mounting holes, and a connecting hook is provided inside the mounting holes. The outer surface of the rotating shaft support has hooks and grooves. The fan blade main body has slots on both sides and elastic extension protrusions on the other two sides. The fan blade main body is connected to the rotating shaft support via the hooks and slots, and a spring is provided between the fan blade main body and the rotating shaft support. The fan blade main body is connected to the connecting hooks on the main body via the elastic extension protrusions.

[0015] Based on the quick-release structure of this grain-stirring fan blade, the detachable connection between the fan blade body and the main body can be achieved solely through a rotating shaft bracket.

Detailed Implementation

[0019] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] The quick-release structure of the food-stirring fan blade in this embodiment is applied to a pet feeder. The fan blade stirs the food as it is dispensed from the feeder. This quick-release structure allows for rapid connection and disassembly of the fan blade body to the main body, facilitating quick disassembly, cleaning, and subsequent maintenance by the user.

[0021] like Figures 1-7 As shown, the quick-release structure of the grain stirring fan blade includes a main body 10, a rotating shaft support 20, and a fan blade body 30.

[0022] like Figure 3 As shown, the main body 10 is the food container of a pet feeder. A mounting hole 11 is provided at the upper end of the main body 10. The mounting hole 11 has a cross-shaped cross section, and connecting hooks 12 extending towards the mounting hole are provided on the two opposing inner surfaces of the mounting hole 11.

[0023] like Figure 4 As shown, the cross section of the rotating shaft bracket 20 is also provided with a cross shape, and it corresponds to the size of the mounting hole 11, so that it can be inserted into the mounting hole 11.

[0024] Two hooks 21 and two grooves 22 are respectively provided on the outer surface of the rotating shaft support 20. The hooks 21 extend outward and are provided on two opposite outer surfaces of the rotating shaft support 20. The grooves 22 have upward openings and are provided on two other opposite sides of the rotating shaft support 20.

[0025] like Figure 5 As shown, the lower end of the fan blade body 30 has an opening, and the cross-section of the opening is cross-shaped, corresponding to the size and shape of the mounting hole 11, allowing it to extend into the mounting hole 11. The fan blade body 30 is provided with a slot 31 and an elastic extension protrusion 32.

[0026] There are two rectangular slots 31, the length of which is set along the height direction of the fan blade body 30, and they are located near the lower end of the fan blade body 30. The two rectangular slots 31 are respectively set on two opposite outer surfaces of the fan blade body 30.

[0027] There are two elastic extension protrusions 32. Openings are provided on two other opposite sides of the fan blade body 30. The inner side of one of the elastic extension protrusions 32 is connected to the inner side of the top of the fan blade body 30 via an elastic connecting rod, and the outer side extends outward from the opening. The other elastic extension protrusion 32 is similarly provided and extends outward from the other opening.

[0028] The connection method for the grain stirring fan blades is as follows: The rotating shaft support 20 extends from the lower end of the fan blade body 30 into the fan blade body 30. A spring is installed inside the fan blade body 30, with its upper end abutting against the top of the inner side of the fan blade body 30 and its lower end abutting against the top of the rotating shaft support 20. Figure 6 , 7 As shown, after the rotating shaft bracket 20 extends into the fan blade body, the two hooks 21 respectively engage with the lower edge of the slot 31, and under the elastic force of the spring, they can be maintained at a position near the lower edge of the fan blade body 30. After connection, as... Figure 2 As shown, insert the fan blade body 30 into the mounting hole 11 of the body 10 until the connecting hook 12 on the body 10 engages above the elastic extension protrusion 32 of the fan blade body 30. At this point, the connection between the fan blade body 30 and the body 10 is complete.

[0029] When it is necessary to disassemble the fan blade body 30 and the main body 10, the rotating shaft bracket 20 is pushed upward by the hook 21, so that it moves upward in the rectangular slot 31, which in turn drives the groove 22 to move upward as well. When the groove 22 moves upward, after contacting the elastic extension protrusion 32 of the fan blade body 30, it continues to move upward, which can retract the elastic extension protrusion 32 into the groove 22, thereby causing the elastic extension protrusion 32 to disengage from the connecting hook 12, thus completing the disassembly of the fan blade body 30 and the main body 10.

[0030] The quick-release structure of the grain-stirring fan blade according to the above embodiment includes a main body, a rotating shaft support, and a fan blade main body. The fan blade main body is sleeved on the outside of the rotating shaft support, and after the fan blade main body is connected to the rotating shaft support, it is detachably connected to the main body. The main body has mounting holes, and a connecting hook is provided inside the mounting holes. The outer surface of the rotating shaft support has hooks and grooves. The fan blade main body has slots on both sides and elastic extension protrusions on the other two sides. The fan blade main body is connected to the rotating shaft support through the hooks and slots, and a spring is provided between the fan blade main body and the rotating shaft support. The fan blade main body is connected to the connecting hooks on the main body through the elastic extension protrusions.

[0031] Based on the quick-release structure of this grain-stirring fan blade, the detachable connection between the fan blade body and the main body can be achieved solely through a rotating shaft bracket. The rotating shaft bracket has a cross-shaped cross section and is inserted from the lower end of the fan blade body. After insertion, the lower end of the fan blade body is then inserted into the mounting hole on the main body. The connection between the fan blade body and the main body is achieved through a connecting hook and an elastic extension protrusion. When disassembly is required, pushing the rotating shaft bracket upwards causes the groove on the rotating shaft bracket to move upwards, retracting the elastic extension protrusion of the fan blade body into the groove, thus separating the fan blade body from the main body. This quick-release structure combines the quick-installation of the rotating shaft bracket and the quick-release / quick-installation structure of the grain-stirring fan blade, saving on structural components and production costs, while also enabling quick-release / quick-installation between the fan blade body and the main body.

[0032] In addition, a spring is installed between the fan blade body and the rotating shaft support, with the upper end of the spring abutting against the top of the inner side of the fan blade body and the lower end abutting against the top of the rotating shaft support. The spring force is used to position the rotating shaft support in a lower position on the fan blade body, thereby allowing the hook to engage with the lower edge of the slot.

[0033] Furthermore, the slot on the fan blade body is rectangular, allowing the hook to move up and down within it. When the hook moves upward, the groove on the rotating shaft bracket can retract the elastic extension protrusion on the fan blade body, thus enabling the fan blade body to be disassembled from the main body.

[0034] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
