Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaner accessories, in particular to a quick installation structure of a vacuum cleaner fan blade. Background Art

[0002] With the advancement of technology and the improvement of consumers' quality of life, vacuum cleaners, as an important part of household appliances, are receiving more and more attention from the market for their performance and ease of use. In the field of vacuum cleaner accessories technology, the fan blades, as a key component of the vacuum cleaner motor, directly affect its suction power and working efficiency.

[0003] The traditional vacuum cleaner fan blade installation structure often uses nuts to fix the fan blades on the rotor shaft. The installation method has low production efficiency and the nuts may become loose after long-term use, affecting the overall performance and user experience of the vacuum cleaner. Therefore, a quick installation structure for vacuum cleaner fan blades is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, such as low production efficiency of the installation method and loose nuts after long-term use, which affects the overall performance and user experience of the vacuum cleaner, and to propose a quick installation structure for the vacuum cleaner fan blade.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A quick installation structure for a vacuum cleaner fan blade includes a rotor shaft, the outer circumferential wall of the rotor shaft being sleeved with a fan blade, the outer circumferential wall of the rotor shaft being provided with two receiving grooves, the two receiving grooves being vertically distributed, a common first slide groove being provided at the center of the two receiving grooves, two second slide grooves being provided on the inner walls on both sides of the receiving groove, and a locking mechanism being provided within the rotor shaft for fixing and connecting the fan blade;

[0007] The locking mechanism includes a slider 1, four sliders 2 and four clips. The slider 1 is slidably connected in the slide groove 1, and the circumferential outer wall of the slider 1 is provided with four grooves, and the connecting shaft 1 is fixedly connected in the groove. The slider 2 is slidably connected in the slide groove 2, and the inner walls on both sides of the slider 2 are fixedly connected with the connecting shaft 2 on one side close to the slider 1. The circumferential outer wall of the connecting shaft 1 and the circumferential outer wall of the connecting shaft 2 are rotatably connected with the same connecting block, and the inner walls on both sides of the slider 2 are rotatably connected with the rotating shaft 1 on the side away from the slider 1, and the clip is rotatably connected to the inside of the receiving groove through a pin shaft, and a receiving groove is provided on the bottom side of the clip. The rotating shaft 2 is rotatably connected in the receiving groove, and the circumferential outer wall of the rotating shaft 1 and the circumferential outer wall of the rotating shaft 2 are fixedly connected with the same spring.

[0008] In a possible design, a circular arc chamfer for rotation is provided on one side of the top of the buckle. When the buckle is in the initial position, the plane on the other side of the top contacts the top inner wall of the receiving groove.

[0009] In a possible design, the top of the buckle is located inside the receiving groove.

[0010] In a possible design, a slope is provided on one side of the buckle to facilitate engagement of the fan blade.

[0011] In a possible design, a bolt for adjusting the first slider is rotatably passed through the top of the rotor shaft, a bottom thread of the bolt passes through the center of the first slider, and the bolt is threadedly connected to the first slider.

[0012] In a possible design, a limiting ring for limiting the position of the fan blade is fixedly connected to the circumferential outer wall of the rotor shaft, and a plurality of slots are provided at the bottom of the fan blade, and the slots are adapted to the limiting ring.

[0013] In this application, when people need to install the fan blade of the vacuum cleaner, they only need to put the fan blade onto the rotor shaft and move it downward. Then, the buckle will rotate inward along the rotating shaft and compress the spring under the movement of the fan blade. When the fan blade contacts and engages with the limit ring, the buckle will reset under the elastic force of the spring and fix the fan blade. When people need to remove the fan blade of the vacuum cleaner, they only need to tighten the bolt. Then the bolt drives slider 1 to move upward. Then slider 1 drives slider 2 through the connecting block and then drives the buckle to rotate inward, and the fan blade can be taken out.

[0014] In the present invention, the quick installation structure of the fan blade of the vacuum cleaner can realize the quick installation of the fan blade by setting the locking mechanism. The user only needs to simply put the fan blade onto the rotor shaft and move it downward, and the buckle can automatically complete the locking without the use of tools, which greatly improves the installation efficiency.

[0015] In the present invention, the quick installation structure of the fan blade of the vacuum cleaner adopts a double locking design of a limiting ring, a clamping groove and a buckle. The engagement of the limiting ring and the clamping groove ensures the stability of the fan blade on the rotor shaft. At the same time, the buckle can fit the fan blade tightly under the elastic force of the spring, effectively preventing it from loosening or falling off, thereby improving the reliability and stability of the operation of the vacuum cleaner.

[0016] In this utility model, the fan blades can be quickly installed. The user only needs to simply put the fan blades onto the rotor shaft and move them downward, and the buckle can automatically lock them without the use of tools, which greatly improves the installation efficiency. The double locking design of the limit ring and the buckle can ensure the stability of the fan blades on the rotor shaft. At the same time, the buckle can fit tightly to the fan blades under the elastic force of the spring, effectively preventing them from loosening or falling off, thereby improving the reliability and stability of the vacuum cleaner operation. The characteristics of quick installation and disassembly make it more convenient for users to replace or clean the fan blades, reduce tedious operating steps, and improve the user experience.
