Description

Technical Field

[0001] The present application relates to the technical field of water pump accessories, and in particular to a water pump fan blade cover. Background Art

[0002] As a common fluid conveying equipment, water pumps are widely used in various industrial, agricultural and daily life occasions. In the structure of water pumps, the fan blade is one of the important components, which is used to drive the fluid movement. In order to protect the fan blade and ensure its normal operation, a fan blade cover is usually installed on the outside of the fan blade.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a water pump fan cover. Figure 1 and Figure 2The water pump fan blade cover mainly includes an outer cover body 1, an inner cover body 2 and a plurality of first reinforcing ribs 3. These first reinforcing ribs 3 are integrally formed between the outer cover body 1 and the inner cover body 2, and are respectively connected to the outer cover body 1 and the inner cover body 2, and at the same time, the first reinforcing ribs 3 are evenly distributed along the circumference of the outer side wall of the inner cover body 2. A connecting groove 4 is formed between the outer cover body 1 and the inner cover body 2, and this connecting groove 4 can allow the motor rear cover to be inserted through interference, so that the water pump fan blade cover is fixedly connected to the motor rear cover, and the water pump fan blade is located on the inner side of the water pump fan blade cover. When the motor rear cover is inserted into the connecting groove 4, its end face will be tightly against the end face of the first reinforcing rib 3.

[0034] Through the composite structural design of the outer cover body 1, the inner cover body 2 and the first reinforcing rib 3, and the interference fit between the motor rear cover and the fan blade cover, the structural strength of the water pump fan blade cover is significantly improved, its deformation resistance is increased, and the deformation of the fan blade cover during transportation and stacking can be effectively prevented; at the same time, by inserting the motor rear cover into the connecting groove 4, the inner cover body 2 is clamped between the motor side wall and the motor rear cover, which can ensure a tight connection between the motor rear cover and the fan blade cover, so that even if it is impacted, the water pump fan blade cover is not easy to separate from the motor rear cover, thereby improving the overall safety of the water pump.

[0035] Reference Figure 2 and Figure 3 In an optional embodiment, a plurality of buckles 5 are added to the end surface of the inner cover 2. These buckles 5 are evenly distributed along the circumference of the inner cover 2 and match the slots on the inner side wall of the motor rear cover. When the motor rear cover is inserted into the connecting slot 4, the buckles 5 will be inserted into the corresponding slots, further enhancing the connection stability between the fan cover and the motor rear cover.

[0036] Reference Figure 2 and Figure 3 Specifically, each buckle 5 includes a connecting plate 51 and a clamping block 52. One end of the connecting plate 51 is integrally formed and connected to the end face of the inner cover body 2, and the other end is fixed with the clamping block 52, and the connecting plate 51 can be bent toward the axial direction of the inner cover body 2 when subjected to force, so as to facilitate the insertion of the motor rear cover. The clamping block 52 is located on the side of the connecting plate 51 facing the outer cover body 1, and a chamfer is provided on the side of the clamping block 52 facing the motor rear cover, and this chamfer forms an inclined surface on the end face of the clamping block 52 to facilitate the insertion of the motor rear cover. When the motor rear cover is inserted into place, the clamping block 52 will be completely inserted into the card slot, thereby achieving a stable connection.

[0037] In addition, a second reinforcing rib 53 is additionally provided on the connecting plate 51 of each buckle 5. The cross section of the second reinforcing rib 53 is a triangular structure, one side of which is connected to the side of the connecting plate 51 away from the outer cover body 1, and the other side is connected to the end face of the inner cover body 2. The provision of the second reinforcing rib 53 further enhances the structural strength of the buckle 5 and improves its ability to resist external forces. At the same time, a plurality of second reinforcing ribs 53 are provided at intervals along the width direction of the connecting plate 51. This design method can also avoid the shrinkage problem of the connecting plate 51 during molding.

[0038] When the motor rear cover is inserted into the connecting groove 4, the first reinforcing rib 3 can limit the displacement of the motor rear cover toward the water pump fan blade cover; at the same time, the buckle 5 can limit the displacement of the motor rear cover away from the water pump fan blade cover, so that the cooperation between the first reinforcing rib 3 and the buckle 5 can limit the forward and backward movement of the water pump fan blade cover and enhance the stability of the installation of the water pump fan blade cover.

[0039] Reference Figure 1 and Figure 2 In this embodiment, a force ring 11 is further provided on the outer side of the end of the outer cover body 1, and the force ring 11 is integrally formed with the outer cover body 1. This force ring 11 can facilitate the user to apply force when installing or removing the fan blade cover, thereby improving the convenience of operation. At the same time, a positioning block is fixed on the outer side wall of the motor rear cover, and correspondingly, a positioning groove 12 for the positioning block to engage is provided on the end face of the outer cover body 1. When the motor rear cover is inserted into the connecting groove 4, the positioning block will be stuck in the positioning groove 12, thereby realizing the precise positioning of the motor rear cover and preventing its displacement during the installation process.

[0040] Reference Figure 1 and Figure 4 In this embodiment, the water pump fan blade cover further includes a back cover 6. The back cover 6 is connected to the end of the outer cover body 1 and the inner cover body 2 away from the motor back cover. A plurality of water holes 61 are provided on the back cover 6. These water holes 61 can ensure the smooth flow of water in and out of the water pump during operation. At the same time, the outer cover body 1, the inner cover body 2, the first reinforcing rib 3 and the back cover 6 are manufactured using an integrated molding process. This process not only simplifies the production process, but also ensures the stability between the outer cover body 1 and the inner cover body 2, and improves the strength of the water pump fan blade cover.

[0041] In order to enhance the structural strength of the rear cover 6, a plurality of third reinforcing ribs 7 are further provided on the rear cover 6. These third reinforcing ribs 7 extend along the diameter direction of the rear cover 6 to form a stable supporting structure. The third reinforcing ribs 7 may be in the shape of a long strip. In this embodiment, the third reinforcing ribs 7 are preferably designed as a "U"-shaped structure to further increase the strength. This design can not only prevent the rear cover 6 from being deformed when subjected to external forces, but also ensure its stability and safety in long-term use.

[0042] The implementation principle of a water pump fan blade cover in an embodiment of the present application is: when installing the water pump fan blade cover, align the positioning groove 12 on the outer cover body 1 with the positioning block of the motor rear cover and slide and insert it, so that the motor rear cover is inserted into the connecting groove 4 with interference fit; at the same time, the clamping block 52 is inserted into the clamping groove; the water pump fan blade cover can be fixed on the water pump.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
