Specific embodiments

[0022] It should be noted that, in the case of no conflict, the embodiments and the features in the embodiments in the application can be combined with each other. The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in the application have the same meaning as that generally understood by ordinary skilled persons in the technical field to which the application belongs.

[0024] In the utility model, the orientation such as "up, down" is generally for the direction shown in the drawing, or for the vertical, perpendicular or gravity direction, unless otherwise stated. Similarly, for the convenience of understanding and description, "left, right" is generally for the left and right shown in the drawing, and "inner, outer" refers to the inner and outer relative to the contour of each component, but the above orientation words are not used to limit the utility model.

[0025] Please refer to Figures 1-6 The utility model provides a kind of high temperature resistant fan impeller, including fan impeller body 1, conical protection plate 2 is fixedly installed on both sides of fan impeller body 1, conical protection plate 2 The side wall of each is fixedly installed with support ring 3.

[0026] Each support ring 3 is equipped with a connecting plate 4 for limited rotation. Specifically, a fixing ring 7 is fixedly installed on the upper end face of the support ring 3, and a rotating shaft 8 is rotatably installed on the fixing ring 7. One end of the connecting plate 4 is fixedly connected to the rotating shaft 8. Further, a limit rod 9 is slidably installed on the side wall of the connecting plate 4 for limited movement. Two fixing seats 10 are fixedly installed on the side wall of the conical protective plate 2. The limit rod 9 is inserted into the fixing seat 10. A lever 11 is fixedly connected to the end of the limit rod 9 away from the fixing seat 10. A spring 12 is sleeved on the outside of the limit rod 9. One end of the spring 12 is fixedly connected to the lever 11, and the other end of the spring 12 is fixedly connected to the side wall of the connecting plate 4. Pulling the lever 11 causes the lever 11 to slide the limit rod 9, causing the spring 12 to extend, allowing the connecting plate 4 to rotate to the position of the upper fixing seat 10. Then, releasing the lever 11 causes the spring 12 to contract, causing the limit rod 9 to enter the interior of the fixing seat 10, thereby limiting the connection plate 4.

[0027] Connecting rods 5 are rotatably mounted on both sides of the connecting plates 4. Specifically, each connecting rod 5 has a rotating groove 13, and a rotating shaft 14 is rotatably mounted inside the rotating groove 13. The rotating shaft 14 is fixedly connected to the connecting plate 4, and a torsion spring is mounted on the rotating shaft 14. One end of the torsion spring is fixedly connected to the inner wall of the rotating groove 13, and the other end of the torsion spring is fixedly connected to the connecting plate 4. Since the connecting rods 5 are connected to the connecting plates 4 through the torsion spring, as... Figure 1 As shown, this causes the connecting rod 5 to abut against the side wall of the conical protective plate 2, limiting the connecting plates 4 on both sides to... Figure 2 After the indicated position is reached, the torsion spring returns to its original state, causing the connecting rod 5 to rotate to... Figure 6 As shown, the connecting rods 5 on the two connecting plates 4 are positioned opposite each other.

[0028] One of the connecting rods 5 has a limiting sleeve 6 threaded on its outer side. Both connecting rods 5 have external threads on their outer sides, and the two connecting rods 5 are connected and limited by the limiting sleeve 6. The limiting sleeve 6 has internal threads inside. Both connecting rods 5 are threadedly connected to the limiting sleeve 6.

[0029] In this embodiment of the invention, multiple reinforcing ribs 15 are uniformly fixed to the outer wall of the conical protective plate 2 around its axis. By providing multiple reinforcing ribs 15, the strength of the conical protective plate 2 can be improved, thereby enhancing the protective effectiveness of the conical protective plate 2 against the fan impeller body 1.

[0030] Working principle:

[0031] When the fan impeller needs to be moved, the connecting plate 4 is positioned outside the support ring 3, with its inner side against the outer wall of the support ring 3. Pulling the lever 11 causes the limiting rod 9 to disengage from the fixed seat 10, thereby releasing the limiting of the connecting plate 4 and allowing it to rotate outside the support ring 3, causing the connecting plate 4 to flip upwards. Figure 2As shown, pulling the push block 11 makes the push block 11 drive the limiting rod 9 to slide, so that the spring 12 is elongated, and the connecting plate 4 can be rotated to the position of the upper fixing seat 10, then the push block 11 is released, the spring 12 is contracted to drive the limiting rod 9 to enter the inside of the fixing seat 10, and then the connecting plate 4 is repositioned. Figure 1 As shown, the connecting rod 5 is abutted on the side wall of the conical protection plate 2, and the connecting plates 4 on both sides are positioned to the position as shown. Figure 2 As shown, the connecting rod 5 is abutted on the side wall of the conical protection plate 2, and the connecting plates 4 on both sides are positioned to the position as shown. Figure 6 As shown, the connecting rod 5 is abutted on the side wall of the conical protection plate 2, and the connecting plates 4 on both sides are positioned to the position as shown. At this time, the user can hold the limiting sleeve 6 to carry the fan impeller. Without the help of external tools, the operation is simple, and the carrying efficiency is improved.

[0032] The above embodiment of the utility model is described in detail in combination with the drawings, but the utility model is not limited to the above embodiment, and various changes can be made within the knowledge range possessed by ordinary skilled in the art without departing from the purpose of the utility model.
