Description

Technical field

[0001] The utility model relates to the technical field of ceiling fans, in particular to a telescopic height-adjustable ceiling fan and a ceiling fan lamp. [Background Technology]

[0002] Ceiling fans are typically fixed to the ceiling, hence the name. They are very effective at cooling down the summer heat. They are typically installed by attaching a mounting base to the ceiling. The mounting base is then equipped with a suspension rod, the lower end of which is fixedly connected to the fan body. However, because the suspension rod and the stator shaft are typically of a fixed length, this structure makes it impossible to adjust the height of the fan body based on the scene or user needs, resulting in inconvenient installation and low practicality.

[0003] Furthermore, some ceiling fan suspension rods typically include an upper rod connected to a mounting base and a lower rod that is adjustable vertically and telescopically connected to the lower end of the upper rod. The lower rod and the upper rod are connected by a threaded connection to enable vertical adjustment. However, this threaded connection requires an additional locking mechanism to lock the lower rod relative to the upper rod, resulting in inconvenient adjustment, complex structure, and high manufacturing costs.

[0004] For this reason, the present invention is studied and proposed in response to the above-mentioned problems. [Utility Model Content]

[0005] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a ceiling fan and ceiling fan light with telescopic adjustable height. The height of the ceiling fan body is adjusted by operating the upper hanging rod to telescopically adjust relative to the lower sleeve. When the ceiling fan body is adjusted to the required height, the upper hanging rod is locked and clamped relative to the lower sleeve through the locking and clamping assembly. Therefore, the height of the ceiling fan can be adjusted according to usage requirements or installation scenarios. The adjustment is convenient and the practicality is high.

[0030] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0031] like Figure 1-7As shown, the utility model is a telescopically height-adjustable ceiling fan, comprising a mounting base 1 and a ceiling fan body 3, wherein the ceiling fan body 3 is connected to the mounting base 1 via a telescopically height-adjustable suspension rod assembly 2; the suspension rod assembly 2 comprises a lower sleeve 21 connected to the ceiling fan body 3 at its lower end, an upper suspension rod 22 which is telescopically adjustable relative to the lower sleeve 21 is connected to the lower sleeve 21, the upper end of the upper suspension rod 22 is connected to the mounting base 1, and the lower sleeve 21 is provided with a locking and clamping assembly 23 for locking the upper suspension rod 22 relative to the lower sleeve 21 when the upper suspension rod 22 is telescopically adjusted to a desired height position relative to the lower sleeve 21. The utility model adjusts the height of the ceiling fan body by operating the upper hanging rod to telescope relative to the lower sleeve (the lower sleeve can also be operated to slide downward or upward relative to the upper hanging rod to adjust the height of the ceiling fan body). When the ceiling fan body is adjusted to the required height, the upper hanging rod is locked and clamped relative to the lower sleeve through the locking and clamping assembly. Therefore, the utility model can adjust the height of the ceiling fan according to usage requirements or installation scenarios, and the adjustment is convenient and practical.

[0032] The upper suspension rod of the utility model is telescopically and slidably connected to the lower casing, which can guide the movement path of the lower casing and ensure that the lower casing can be smoothly adjusted in the up and down directions.

[0033] In order to achieve more accurate adjustment and reliable locking, the upper suspension rod 22 and the lower casing 21 can be steplessly adjusted and locked via a locking and clamping assembly 23 .

[0034] In order to more reliably hold the upper suspension rod, the locking and holding assembly 23 is configured to act on the lower sleeve 21 to hold and lock the upper suspension rod 22. In this embodiment, the upper part of the locking and holding assembly 23 holds the upper suspension rod, and the lower part holds the upper suspension rod by acting on the lower sleeve 21.

[0035] like Figure 1-3 As shown, the locking and clamping assembly 23 includes an annular locking and clamping member 231 that is sleeved on the lower sleeve 21. A clamping member opening 2311 is defined on the sidewall of the locking and clamping member 231. A clamping locking member 232 is provided on the locking and clamping member 231 at the location of the clamping member opening 2311. In this embodiment, the clamping locking member 232 can be a clamping locking screw. During adjustment, the size of the clamping member opening 2311 can be adjusted by tightening the nut of the clamping locking screw, making adjustment convenient.

[0036] like Figure 3 As shown, the upper portion of the inner wall of the locking clamping member 231 has a clamping convex ring for cooperating with the upper port of the lower casing to block and limit, and the clamping convex ring is used to clamp and cooperate with the upper suspension rod, and the installation and positioning are accurate.

[0037] like Figure 1-3As shown, for ease of operation, the corresponding end of the clamping lock member 232 is connected to a clamping handle 233 for controlling the clamping lock member 232 to adjust the size of the clamping member opening 2311. The clamping handle 233 is rotatably connected to the corresponding end of the clamping lock member 232. The clamping handle 233 has a handle locking protrusion for engaging with the locking clamping member 231. The clamping handle 233 is rotated to engage the handle locking protrusion with the locking clamping member 231, thereby pulling the clamping lock member 232 to reduce the clamping member opening 2311 (or, in other words, the handle locking protrusion pushes one end of the clamping member opening 2311 toward the other end), thereby causing the locking clamping member 231 to clamp the lower casing.

[0038] like Figure 1-3 As shown, in order to facilitate the deformation of the lower sleeve by the locking and clamping assembly so that the inner wall of the lower sleeve fits more closely with the outer wall of the upper suspension rod, thereby ensuring that the lower sleeve clamps the upper suspension rod more firmly and reliably, an open groove 211 extending along its length direction is provided on the upper part of the lower sleeve 21, and a sleeve through hole 212 communicating with the lower end of the open groove 211 is also provided on the upper part of the lower sleeve 21.

[0039] like Figure 4-7 As shown, in order to ensure safety in use, an anti-falling assembly 4 is also included for preventing the ceiling fan body 3 from falling when the ceiling fan body 3 is separated from the suspension rod assembly 2.

[0040] like Figure 4-7 As shown, in order to facilitate and ensure reliable connection, the anti-falling assembly 4 includes an anti-falling connector 41 at its upper end for connection to the mounting base 1 or an external fixing portion, and the lower end of the anti-falling connector 41 passes through the suspension rod assembly 2 and the motor rod of the ceiling fan body 3 in sequence and is exposed on the lower side of the ceiling fan body 3. The lower part of the anti-falling connector 41 is provided with an anti-falling stopper 42 for blocking and cooperating with the lower side of the ceiling fan body 3, and the lower end of the anti-falling connector 41 is provided with an anti-falling limiter 43 for preventing the anti-falling stopper 42 from separating from the anti-falling connector 41. The anti-falling connector 41 can be an anti-falling connecting steel rope, etc., to reduce manufacturing costs and lighten weight. Figure 5 As shown, the cross-sectional diameter of the anti-fall blocking member 42 is larger than the diameter of the lower port of the motor shaft.

[0041] like Figure 4-7 As shown, for easy connection, the anti-falling limiter 43 is provided with a first connecting hole 431 and a second connecting hole 432 . After the lower end of the anti-falling connector 41 passes downward through the first connecting hole 431 , it is bent and passes upward through the second connecting hole 432 .

[0042] The utility model provides a telescopic height-adjustable ceiling fan lamp, which comprises the telescopic height-adjustable ceiling fan as described above, wherein the lower end of the ceiling fan body 3 is connected to a lighting assembly 5 .
