Description

Technical Field

[0001] The utility model relates to the technical field of ceiling fans, in particular to a ceiling fan blade installation structure. Background Art

[0002] After a ceiling fan has not been used for a certain period of time, dust will accumulate on the blades of the ceiling fan. Too much dust will cause the blade surface to be rough, causing vibrations when the ceiling fan is running, affecting the wind force and causing harm to the human respiratory tract. Therefore, it is necessary to clean the dust on the fan blades in time.

[0003] In existing ceiling fans, the fan blades are fixed to the fan head by screws, and the fan head is suspended from the ceiling at a certain height. The dust on the fan blades is mainly concentrated on the side of the fan blades facing the ceiling. It is necessary to climb up to clean the fan blades. For ceiling fans with long fan blades, it is also necessary to move the position to completely clean the fan blades, which is very inconvenient. Utility Model Content

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.

[0016] like Figure 1-Figure 2As shown, a ceiling fan blade mounting structure comprises a fan head 1, three fan blades 2, three first connecting arms 3, three second connecting arms 4 and three locking mechanisms, wherein the first end of the first connecting arm 3 is fixedly connected to the fan head 1, the three first connecting arms 3 are evenly arranged along the circumference of the fan head 1, and the first connecting arm 3 is horizontally arranged, the first ends of the three second connecting arms 4 are respectively hinged to the second ends of the three first connecting arms 3 by bolt pins, the hinge axes of the second connecting arms 4 are horizontally arranged, and the hinge axes of the second connecting arms 4 are perpendicular to the radial direction of the fan head 1, the three fan blades 2 are respectively fixed to the second ends of the three second connecting arms 4 by bolts, and the first connecting arm 3 is installed with a locking mechanism, and when the first connecting arm 3 and the second connecting arm 4 are parallel, the locking mechanism can keep the first connecting arm 3 and the second connecting arm 4 fixed. Specifically, the locking mechanism includes a sleeve 5, a first protrusion 51, an insertion rod 52 and an elastic member 6. The sleeve 5 is slidably mounted on the first connecting arm 3. The top of the sleeve 5 is fixedly connected to the first protrusion 51. The side of the first protrusion 51 facing away from the fan head 1 is fixedly connected to the insertion rod 52. The top of the second connecting arm 4 is fixedly connected to the second protrusion 41. The side of the second protrusion 41 facing the first protrusion 51 is provided with a countersunk hole 42 that matches the insertion rod 52. When the first connecting arm 3 and the second connecting arm 4 are parallel, the insertion rod 52 can be inserted into the countersunk hole 42. The top edge of the fan head 1 is provided with a third protrusion 11 corresponding to the first protrusion 51. An elastic member 6 is provided between the third protrusion 11 and the corresponding first protrusion 51. The elastic member 6 drives the sleeve 5 to move toward the outside of the fan head 1, thereby preventing the insertion rod 52 from detaching from the countersunk hole 42.

[0017] In actual applications, by inserting the insertion rod 52 into the corresponding countersunk hole 42, the fan blades 2 can be lifted and leveled, so that the ceiling fan has the function of blowing air. When the fan blades 2 need to be cleaned, the sliding sleeve 5 is slid toward the fan head 1 to allow the insertion rod 52 to be disengaged from the countersunk hole 42, thereby allowing the second connecting arm 4 to move, and then the fan blades 2 are rotated downward, so that the fan blades 2 are set longitudinally, and the fan blades 2 can be effectively cleaned without moving their position.

[0018] In this embodiment, a buckle plate 53 is fixed to the bottom of the sliding sleeve 5 to facilitate buckling the sliding sleeve 5 .

[0019] In this embodiment, a guide rod 54 is fixedly connected to the side of the first protrusion 51 facing away from the insertion rod 52. The guide rod 54 is slidably inserted into the corresponding third protrusion 11. The elastic member 6 is a compression spring, which is sleeved on the guide rod 54. The material is easy to obtain, easy to process and manufacture, and can ensure the stability of the movement of the sliding sleeve 5.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. All modifications, equivalent substitutions, improvements, etc. within the spirit and principles of the present invention should be included in the protection scope of the present invention.
