Description

Technical Field

[0001] This utility model relates to the field of fan blade installation technology, and in particular to a novel quick-installation fan blade. Background Technology

[0002] A ceiling fan, also known as a ceiling fan, is a type of fan installed on the ceiling. It mainly consists of a motor, fan blades, a hanging rod, and a control unit. The motor drives the fan blades to rotate, accelerating airflow and creating a breeze, thus providing a cooling sensation. Ceiling fans typically have 3 or 5 blades, and their shape and angle are designed to improve airflow efficiency. The fan speed and airflow can be adjusted via a control unit, commonly using pull-cord switches or remote control. Ceiling fans are suitable for larger spaces such as living rooms, dining rooms, offices, and factory workshops, offering advantages such as saving floor space and providing a large coverage area.

[0003] Currently, existing ceiling fans on the market have certain limitations in design, with most featuring integrated blades and the fan body. While this design ensures overall stability and aesthetics to some extent, it introduces numerous inconveniences during subsequent use. After prolonged use, due to various reasons such as accidental impacts or natural aging, replacing a damaged blade becomes extremely difficult. Because the integrated design tightly connects the blade to the body, unlike detachable blade designs that allow for easy individual replacement, it often requires professional assistance with specific tools and complex procedures—a task virtually impossible for ordinary users. Therefore, this design makes ceiling fans inconvenient to use, increases maintenance costs and difficulty, and causes considerable inconvenience for users.

[0004] Therefore, those skilled in the art have provided a novel quick-installation fan blade to solve the problems mentioned in the background art. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Reference Figures 1-8 The present invention provides an embodiment of a novel quick-install fan blade, comprising an installation housing 1 and three fan blade bodies 2. One end of the fan blade body 2 is fixedly connected to an installation plate 4. An installation hole 7 is provided at the center of the upper surface of the installation plate 4. A first-numbered locking hole 3 is provided on the upper surface of the installation plate 4 located on both sides of the installation hole 7. Two oblique grooves 6 are provided on the lower end of the side of the installation plate 4 away from the fan blade body 2. The outer casing 1 is fitted with three mounting boxes 14 at equal intervals. The center of the lower end face of the mounting box 14 is fixed with an upper threaded post 13. The lower end face of the mounting box 14 on both sides of the upper threaded post 13 is fixed with a lower threaded post 16. The bottom surface of the mounting box 14 is provided with a third locking hole 17 on both sides. The top surface of the mounting box 14 is provided with a second locking hole 15 on both sides. The lower end of the two lower threaded posts 16 is threaded with a fixing bolt 12. The upper end of the head of the two fixing bolts 12 is fixedly connected with a spring 11. The two springs 11 are fixedly connected to a movable plate 8. The center of the upper end face of the movable plate 8 is provided with a bolt insertion hole 5. The upper end face of the movable plate 8 is fixedly provided with trapezoidal locking blocks 10 on both sides. The inclined groove 6 and the first locking hole 3 are aligned on the same straight line. The main bodies of the lower hole threaded post 16 and the fixing bolt 12 are movably sleeved inside the spring 11. The upper part of the lower hole threaded post 16 is movably sleeved inside the movable plate 8. The upper part of the upper part of the upper hole threaded post 13 is movably set inside the bolt insertion hole 5. The mounting bolt 9 is movably set inside the mounting hole 7. The lower end of the mounting bolt 9 is threaded inside the upper hole threaded post 13. The first locking hole 3, the second locking hole 15, and the third locking hole 17 are perpendicular to each other on the same straight line. The upper end of the trapezoidal locking block 10 extends into the first locking hole 3, the second locking hole 15, and the third locking hole 17.

[0016] Specifically, this device utilizes a unique snap-fit ​​design, allowing the fan blade body 2 to be quickly installed onto the mounting housing 1. Specifically, the inclined groove 6 on the mounting plate 4 contacts the inclined surface of the trapezoidal snap-fit ​​block 10, causing the trapezoidal snap-fit ​​block 10 to be pressed down during insertion, compressing the spring 11 and causing the movable plate 8 to move downwards. Once fully inserted, the trapezoidal snap-fit ​​block 10 moves upwards under the restoring force of the spring 11, passing through the first snap-fit ​​hole 3 and entering the second snap-fit ​​hole 15, achieving initial engagement. This process requires no complex tools and can be easily completed by ordinary users.

[0017] After the initial snap-fit ​​is completed, the mounting bolt 9 is threaded into the upper hole's internal threaded post 13 through the mounting hole 7, further increasing the fan blade's stability. This double-fixing method ensures the fan blade's stability during high-speed rotation and reduces the risk of loosening or falling off due to vibration.

[0018] The fan blade body 2 and the mounting housing 1 adopt a modular design, making the replacement of individual fan blades simple and easy. When a fan blade is damaged, only that fan blade needs to be removed and replaced, without disassembling the entire ceiling fan, greatly reducing maintenance costs and difficulty. This utility model is applicable to various specifications of ceiling fans and has wide applicability. By adjusting the dimensions of the mounting box 14 and the fan blade body 2, it can be adapted to different models of ceiling fans, improving the product's versatility and market competitiveness.

[0019] Working principle: When the fan blade body 2 is not installed, the spring force of the spring 11 causes the movable plate 8 to move to the top and fit against the lower surface of the mounting box 14. At this time, the trapezoidal block 10 will pass through the inside of the second and third locking holes 15 and 17. During installation, first hold the fan blade body 2 and insert the mounting plate 4 into the mounting box 14. During insertion, the inclined surface of the inclined groove 6 contacts the inclined surface of the trapezoidal locking block 10. Under the pressure of horizontal insertion, the trapezoidal locking block 10 is pressed down, the spring 11 is compressed, and the movable plate 8 moves down. After the mounting plate is fully inserted, the first locking hole 3 will move to the upper end of the trapezoidal locking block 10. The trapezoidal locking block 10 is no longer squeezed by the mounting plate 4. Under the action of the spring 11, the movable plate 8 moves up and returns to its original position. The trapezoidal locking block 10 moves up and passes through the first locking hole 3 and finally enters the interior of the second locking hole 15, thus completing the initial locking installation. At this time, the mounting hole 7 and the upper hole internal thread post 13 are perpendicular to each other on the same straight line. Then, take out the mounting bolt 9 and insert it into the mounting hole 7 to connect with the upper hole internal thread post 13, further increasing the firmness. Finally, the installation is completed. The installation is quick, simple to operate, convenient to use, and easy to replace the fan blade.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
