Description

Technical Field

[0001] This utility model relates to the field of ceiling fan technology, and in particular to a height-adjustable decorative cover for a ceiling fan. Background Technology

[0002] Ceiling fans are common air conditioning devices, typically installed on the ceiling. Ceiling fans include decorative ceiling fans (ceiling fan lights), industrial ceiling fans, and vintage ceiling fans, among others.

[0003] Ceiling fans typically require a hanging rod for installation. The hanging rod, as the mounting component, is usually fixed to the mounting surface (ceiling) at its upper end, with the ceiling fan installed at its lower end. Existing hanging rod structures often feature a cylindrical decorative cover. The applicant previously applied for a decorative cover device for a ceiling fan / light pole, which is vertically adjustable to better accommodate light poles and mounting rods of different lengths. However, this structure has the following drawbacks: 1. The overall structural design is relatively complex, making adjustment inconvenient; 2. Poor overall integrity, resulting in numerous gaps, which are unsightly and difficult to clean; 3. Radial wobbling can occur between the components of the decorative cover.

[0004] Therefore, how to provide an adjustable height ceiling fan cover with a simpler and more reasonable structural design, easier adjustment and operation, better overall integrity, and more stable and reliable cooperation between components has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to provide an adjustable height ceiling fan decorative cover with a simpler and more reasonable structural design, more convenient adjustment and operation, better overall integrity, and more stable and reliable cooperation between components.

[0006] To achieve the above objectives, this utility model provides an adjustable height ceiling fan decorative cover, comprising a decorative cover with an overall cylindrical structure and fitted onto the outside of the hanging rod; the decorative cover includes a lower connecting cover and an upper adjusting cylinder; characterized in that; at least a portion of the upper end of the connecting cover has a cylindrical structure to form a connecting cylinder, such that the adjusting cylinder is fitted onto the outside of the connecting cylinder; a plurality of inwardly protruding protrusions are evenly provided on the inner circumferential surface of the adjusting cylinder along the circumferential direction; a mating structure is provided on the outer circumferential surface of the connecting cylinder corresponding to each protrusion; the mating structure includes a plurality of vertically spaced recesses, and adjusting the axial position of the adjusting cylinder on the connecting cylinder allows the protrusions to be sequentially fitted into the recesses, thereby limiting the axial position between the connecting cylinder and the adjusting cylinder.

[0007] Thus, in the above-mentioned adjustable height ceiling fan decorative cover structure, the axial positioning of the connecting cylinder and the adjusting cylinder is achieved through the cooperation of the protrusion and the notch, which makes it easier to adjust the vertical position between the two without the aid of tools; secondly, the adjusting cylinder is sleeved outside the connecting cylinder, resulting in fewer gaps in the entire structure, making it more aesthetically pleasing and easier to clean, and the connecting cylinder and the adjusting cylinder will not wobble in the radial direction after they are engaged.

[0008] As an optimization, two inwardly protruding protrusions are evenly provided on the inner circumferential surface of the adjusting cylinder along the circumferential direction, and the mating structure consists of two correspondingly arranged protrusions.

[0009] In this way, while ensuring the axial positioning stability of the docking cylinder and the adjusting cylinder, the number of protrusions is arranged more reasonably, making it more convenient for processing and manufacturing.

[0010] As an optimization, the mating structure includes a mating strip integrally formed on the inner peripheral wall of the docking cylinder and arranged in the axial direction, such that the bottom surface of the notch penetrates the wall thickness of the docking cylinder and extends correspondingly onto the mating strip.

[0011] In this way, by arranging mating strips on the inner circumferential wall of the docking cylinder, the docking cylinder is strengthened on the one hand, and the notch can be set more conveniently and the depth of the notch can be increased on the other hand.

[0012] As an optimization, the regulating cylinder includes a left half and a right half with a semi-circular cross-section, and the left half and the right half are connected and fixed together by screws; a protrusion is provided on the inner side of the lower end of the left half and the right half of the regulating cylinder.

[0013] In this way, the adjustment cylinder is set into two independent left and right halves, which makes it easier to process and manufacture, and also easier to disassemble and assemble.

[0014] As an optimization, the lower ends of the left and right halves of the adjusting cylinder are each bent inward horizontally to form a bent flange, and each of the bent flanges is provided with the aforementioned protrusion.

[0015] In this way, by bending the lower ends of the left and right halves of the adjusting cylinder to form bent flanges, and then forming protrusions on the bent flanges, the cylinder has better deformation capacity. During adjustment, the protrusions can be better protected and broken.

[0016] As an optimization, the docking cover includes a connecting cylinder with an overall frustum-shaped structure at the lower end. The upper end of the connecting cylinder bends inward to form a connecting plate, and the docking cylinder is integrally formed on the connecting plate. The middle part of the connecting plate is drawn downward to form an installation cylinder, and the lower end of the installation cylinder bends inward horizontally to form a ring-shaped installation ring plate. A connecting plate is installed below the installation ring plate, and the upper side of the middle part of the connecting plate protrudes upward to form a connecting sleeve. A vertically upward hanging rod is connected to the connecting sleeve.

[0017] This design simplifies and optimizes the overall structure of the docking cover. It also allows for better installation and fixation on the hanger rod, ensuring the hanger rod and docking cylinder are coaxial. This better prevents swaying between the decorative cover and the hanger rod, and also facilitates assembly.

[0018] Furthermore, the mounting ring plate has three inwardly protruding connecting protrusions, and the connecting disc is fixed to the connecting protrusions by connecting screws.

[0019] As an optimization, the connecting cylinder is designed as a frustum-shaped structure with a smaller diameter at the top and a larger diameter at the bottom; and the outer diameter of the connecting cylinder is set to be less than or equal to the diameter at the top of the connecting cylinder.

[0020] This simplifies the structural design of the connecting cylinder and makes the entire structure more aesthetically pleasing.

[0021] As an optimization, the lower end of the connecting cylinder has a connecting sleeve that extends vertically downward.

[0022] In this way, by setting a connecting sleeve at the lower end of the connecting cylinder, it can better connect and cooperate with the structural components located below it.

[0023] As an optimization, arc-shaped mounting plates are installed on both sides of the boom, and the two mounting plates are fixed to the upper end of the boom by bolts; mounting pulleys are rotatably installed between the upper ends of the mounting plates.

[0024] By setting two mounting plates and installing a mounting pulley between them, it becomes easier to install the mounting pulley.

[0025] As an optimization, the boom is a hollow rod structure.

[0026] By making the suspension rods hollow, the entire structure can be made lighter.

[0027] In summary, the above structure, by setting mutually cooperating protrusions and recesses on the adjusting cylinder and the docking cylinder respectively, makes the axial limiting structure design simpler and more convenient for adjustment. Furthermore, it has better overall integrity and the cooperation between components is more stable and reliable. Attached Figure Description

The mating structure includes a plurality of vertically spaced recesses 6, and adjusting the axial position of the adjusting cylinder on the connecting cylinder allows the protrusions to be sequentially fitted into the recesses to limit the axial position between the connecting cylinder and the adjusting cylinder.

[0040] Thus, in the above-mentioned adjustable height ceiling fan decorative cover structure, the axial positioning of the connecting cylinder and the adjusting cylinder is achieved through the cooperation of the protrusion and the notch, which makes it easier to adjust the vertical position between the two without the aid of tools; secondly, the adjusting cylinder is sleeved outside the connecting cylinder, resulting in fewer gaps in the entire structure, making it more aesthetically pleasing and easier to clean, and the connecting cylinder and the adjusting cylinder will not wobble in the radial direction after they are engaged.

[0047] In this specific embodiment, the lower ends of the left half and the right half of the adjusting cylinder are each bent inward horizontally to form a bent flange 10, and each of the bent flanges is provided with the protrusion.
