Detailed Implementation Methods

[0036] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0037] like Figures 1-6 As shown, this utility model includes a quick-installation mechanism for fixing the upper cup in a ceiling fan. The ceiling fan includes a ceiling fan body and a hanging rod 1 that connects the ceiling fan body to the ceiling. It also includes an upper cup 2 disposed on the hanging rod 1. The quick-installation mechanism 3 is disposed on the hanging rod 1 and can be adjusted up and down along the length of the hanging rod 1. The quick-installation mechanism 3 includes an installation sleeve assembly 31 sleeved on the hanging rod 1 and a locking assembly 32 connected to the installation sleeve assembly 31 to lock the entire quick-installation mechanism 3 and the upper cup 2 on the hanging rod 1.

[0038] like Figure 1As shown, the quick-mounting mechanism 3 is arranged on the hanger bar 1, the locking assembly 32, the upper can 2 and the mounting sleeve assembly 31 are sequentially arranged on the hanger bar 1, and the position of the mounting sleeve assembly 31 can be adjusted along the length direction of the hanger bar 1. When reaching the preset position, the locking assembly 32 cooperates with the mounting sleeve assembly 31 to fix and lock the quick-mounting mechanism 3 at the preset position on the hanger bar 1. At this time, the upper can 2 is firmly locked between the mounting sleeve assembly 31 and the locking assembly 32, thereby providing stable support for the upper can 2 and ensuring the stability of the upper can 2 and the hanger bar 1 as a whole. In addition, since the mounting sleeve assembly 31 can be adjusted up and down along the length direction of the hanger bar 1, the installation position of the upper can 2 can be flexibly adjusted according to actual installation requirements and ceiling height and the like. The mounting sleeve assembly 31 cooperates with the locking assembly 32 to be connected, thereby fixedly locking the quick-mounting mechanism 3 and the upper can 2 at the preset position, and the flexibility of the installation of the upper can 2 is improved. Compared with the prior art, the locking mode is formed by the upper can 2 structure integrally formed with the external thread column and the nut. The present application fixes the upper can 2 at the preset position on the hanger bar 1 through the quick-mounting mechanism 3, solves the problem that the upper can 2 is integrally formed with the external thread column in the prior art, and the mold for producing different models of the upper can 2 matched with the external thread column and the increase of the accessory inventory burden are required. The quick-mounting mechanism 3 can be manufactured separately and adapted to different upper cans 2 to meet the installation requirements, thereby reducing the overall manufacturing cost of the ceiling fan and having good universality. The quick-mounting mechanism 3 also has the advantages of convenient installation operation and reliable structure.

[0039] As shown in Figure 2 , Figure 3 As a further technical solution of the present application, the mounting sleeve assembly 31 includes a connecting part 312 in a hollow shape for locking the upper can 2 on the hanger bar 1. The upper end of the connecting part 312 is provided with a boss part 311 for positioning the mounting sleeve assembly 31 inside the upper can 2. The connecting part 312 narrows from top to bottom to form an elastic clamping part 313 for clamping the hanger bar 1. The locking assembly 32 includes an adjusting part 321 in a hollow shape and a fixing part 322 extending downward from the adjusting part 321. The fixing part 322 narrows from top to bottom to form a bowl-shaped structure 3221. During installation, the mounting sleeve assembly 31 cooperates with the locking assembly 32 through the adjusting part 321 and the connecting part 312 to act on the fixing part 322 to extrude the elastic clamping part 313 so that the elastic clamping part 313 clamps the hanger bar 1, thereby locking the quick-mounting mechanism 3 and the upper can 2 at the preset position on the hanger bar 1. The mounting sleeve assembly 31 is integrally formed, the upper end of which forms the boss part 311, the middle section forms the connecting part 312, and the lower end forms the elastic clamping part 313. The mounting sleeve assembly 31 is in a hollow shape as a whole to allow the hanger bar 1 to pass through. The locking assembly 32 is integrally formed with the adjusting part 321 and the fixing part 322. The locking assembly 32 is in a hollow shape and cooperates with the mounting sleeve assembly 31.

[0040] As shown in Figure 1 ,Figure 5 As shown, the inner bottom surface of the upper can 2 is provided with a mounting channel 21 for the passing of the hanger bar 1. When the quick mounting mechanism 3 is mounted, the locking assembly 32, the upper can 2 and the mounting sleeve assembly 31 are sequentially sleeved on the hanger bar 1, and the mounting sleeve assembly 31 can be clamped on the hanger bar 1 through the elastic clamping portion 313. Since the elastic clamping portion 313 has elasticity and will be elastically deformed adaptively during the movement of the mounting sleeve assembly 31. According to the mounting preset height of the upper can 2, the operator pushes the upper can 2 with one hand, and the inner part of the upper can 2 abuts against the boss portion 311 of the mounting sleeve assembly 31, and both of them move upward on the hanger bar 1 until the upper can 2 reaches the preset position. When it is needed to move downward to adjust the position, the mounting sleeve assembly 31 is operated to move downward, and the upper can 2 is naturally lowered. After reaching the preset position, the other hand moves the locking assembly 32 upward, and the locking assembly 32 is connected and matched with the connecting portion 312 through the adjusting portion 321 to be locked, and the fixing portion 322 presses the elastic clamping portion 313 to strengthen the clamping force of the hanger bar 1, and the locking is continued until the elastic clamping portion 313 is fully clamped on the hanger bar 1, so that the quick mounting mechanism 3 and the upper can 2 are firmly locked on the preset position of the hanger bar 1, and the mounting operation is completed. In the locked state, the quick mounting mechanism 3 is clamped on the hanger bar 1, and the upper can 2 is locked between the boss portion 311 and the adjusting portion 321.

[0041] Specifically, as shown in the drawings, Figures 1 to 3 As a further technical solution of the present application, the outer side surface of the connecting portion 312 is provided with external threads, and the inner side surface of the adjusting portion 321 is provided with internal threads; conversely, the outer side surface of the connecting portion 312 is provided with internal threads, and the inner side surface of the adjusting portion 321 is provided with external threads, and the connecting portion 312 and the adjusting portion 321 are connected through thread matching. When it is needed to mount the upper can 2, the locking assembly 32 is tightened in the tightening direction, the bottom surface of the upper can 2 is stopped by the locking assembly 32, the locking action is stopped, and the elastic clamping portion 313 is fully clamped on the hanger bar 1. When it is needed to dismount the upper can 2, the locking assembly 32 is loosened, the locking assembly 32 is rotated in the reverse direction of the tightening direction, the tightening force between the adjusting portion 321 and the connecting portion 312 is reduced, the pressure of the fixing portion 322 on the elastic clamping portion 313 is reduced, the elastic clamping portion 313 partially releases the clamping action on the hanger bar 1, and the quick mounting mechanism 3 is quickly disassembled, which is simple in operation and reliable in structure. Compared with the traditional fixing method such as using screws to fix the upper can 2 on the hanger bar 1 or the ceiling, the connecting method of the quick mounting mechanism 3 for fixing the upper can 2 through thread matching avoids the complicated installation process of punching holes on the hanger bar 1 or the ceiling, has the advantages of convenient installation and stable and reliable advantages, and increases the overall beauty of the ceiling fan.

[0042] In addition, the connecting portion 312 and the adjusting portion 321 can also be connected through a clamping structure (not shown in the drawings).

[0043] As shown in the drawings, Figure 1 , Figure 2, Figure 4 , Figure 5 As shown, as a further technical solution of this application, the elastic clamping part 313 has a funnel-shaped tightening structure 34. The elastic clamping part 313 is composed of several clamping pieces 3131, and each clamping piece 3131 has a protruding structure 35 at its end for pressing against the lifting rod 1. The elastic clamping part 313 can be made of plastic material with elasticity. Its combination with the funnel-shaped tightening structure 34 allows it to not only provide sufficient clamping force during clamping, but also to adapt to lifting rods 1 of different diameters within a certain range. The combination of the funnel-shaped tightening structure 34 and the protruding structure 35 makes the clamping force on the lifting rod more uniform and stable, avoiding the slippage or loosening problems caused by insufficient rigidity in traditional clamping structures. The bowl-shaped structure 3221 of the fixing part 322 provides additional support and locking functions to ensure the stability and reliability of the upper cup 2.

[0044] like Figure 5 , Figure 6 As shown, as a further technical solution of this application, the mounting sleeve assembly 31 is provided with an anti-rotation part 41 to prevent the mounting sleeve assembly 31 from rotating relative to the upper cup 2 when the quick-release mechanism 3 is installed. Correspondingly, the upper cup 2 is provided with a limiting part 42 that cooperates with the anti-rotation part 41. When fixing the quick-release mechanism 3, if the quick-release mechanism 3 tightens the locking component 32 around the mounting sleeve assembly 31 by means of threaded locking, when the tightening force between the locking component 32 and the mounting sleeve assembly 31 is greater than the clamping force of the elastic clamping part 313, the mounting sleeve assembly 31 may rotate due to the clamping force of the elastic clamping part 313 alone. Therefore, in order to further improve installation efficiency, the mounting sleeve assembly 31 and the locking assembly 32 are connected by an anti-rotation part 41 and a limiting part 42 to prevent rotation between the mounting sleeve assembly 31 and the upper cup 2. The upper cup 2 can be quickly tightened and fixed by the locking assembly 32 and the mounting sleeve assembly 31, thereby improving the operational stability of the quick-installation mechanism 3 and simplifying operation.

[0045] Specifically, such as Figure 5 As shown, in one embodiment of this technical solution, the anti-rotation part 41 is a protrusion 411 located between the boss part 311 and the connecting part 312. Correspondingly, the limiting part 42 is a slot 421 located at the junction of the upper cup 2 and the mounting sleeve assembly 31. The protrusion 411 and the slot 421 engage in a snap-fit ​​relationship. The size of the slot 421 is adapted to the size of the protrusion 411. During installation, the protrusion 411 on the mounting sleeve assembly 31 engages in the slot 421 on the upper cup 2, forming a snap-fit ​​relationship to prevent rotation between the mounting sleeve assembly 31 and the upper cup 2. The upper cup 2 can be quickly and securely tightened by screwing the locking assembly 32 and the mounting sleeve assembly 31 together.

[0046] like Figure 6As another setting mode of the technical solution, the rotation-stopping part 41 is a protrusion 412 arranged on the outer edge of the boss part 311, and the limiting part 42 is a concave clamping seat 422 arranged on the upper can 2, and the protrusion 412 and the concave clamping seat 422 are in clamping cooperation. The concave clamping seat 422 forms a groove, and the size of the groove is matched with the size of the protrusion 412. When installed, the protrusion 412 on the mounting sleeve assembly 31 is clamped in the concave clamping seat 422 on the upper can 2, and the two form clamping cooperation to prevent rotation between the mounting sleeve assembly 31 and the upper can 2. The upper can 2 can be fixed by quickly tightening the locking assembly 32 and the mounting sleeve assembly 31.

[0047] Further, the limiting part 42 can be provided with a plurality of limiting parts 42, which are arranged along the circumference of the installation channel 21. The rotation-stopping part 41 is correspondingly provided with a plurality of rotation-stopping parts 41, and each limiting part 42 corresponds to one rotation-stopping part 41, thereby enhancing the stability of the structure.

[0048] As shown in Figure 1 In order to facilitate the locking process between the mounting sleeve assembly 31 and the locking assembly 32, as a further technical solution of the application, the outer side of the locking assembly 32 is provided with anti-slip lines 5 for increasing the friction when the locking and quick assembly mechanism 3 is locked. In the technical solution of the application, the anti-slip lines 5 arranged on the outer side of the locking assembly 32 can effectively increase the friction when the locking and quick assembly mechanism 3 is locked. This design not only improves the gripping force of the locking assembly 32 and reduces the risk of sliding, but also makes the operation more convenient and efficient.

[0049] As a further technical solution of the application, the mounting sleeve assembly 31 and the locking assembly 32 are made by injection molding. The mounting sleeve assembly 31 and the locking assembly 32 are made of plastic material with certain elastic deformation. Compared with the existing technology in which the upper can 2 and the outer threaded column are formed integrally, since the upper can 2 is usually made of metal material by stamping process, the quick assembly mechanism 3 in the application is made by injection molding production method, and the made quick assembly mechanism 3 is used in cooperation with the upper can 2, which effectively reduces the overall manufacturing and material production cost of the ceiling fan, and has the characteristics of high efficiency, flexibility, high precision, etc.
