Description

Technical Field

[0001] The utility model relates to the technical field of impeller brackets, and particularly relates to a split impeller bracket. Background Technique

[0002] When assembling a ceiling fan, it is usually necessary to fixedly install the fan blades through an impeller bracket to ensure the stability of the fan blades during operation and the overall structure of the ceiling fan. However, there are still certain defects in the existing impeller brackets during use;

[0003] For example, a fan blade installation component proposed in the application number CN202221266228.1 includes a motor ceiling fan head. An annular fan blade groove is provided on the side wall of the motor ceiling fan head. A fan blade component is installed in the annular fan blade groove. It also includes a positioning ring and a positioning strip. The positioning ring is arranged in the annular fan blade groove and is concentric with the annular fan blade groove. The positioning strip is fixedly arranged in the annular fan blade groove. A bolt hole is provided on the fan blade component, and a threaded hole is penetrated through the motor ceiling fan head. When one end of the fan blade component abuts against the positioning ring and one side of the fan blade component abuts against the positioning strip, the bolt hole and the threaded hole are coaxially arranged. In the actual use process, the fan blade installation component positions one end and one side of the fan blade component through the positioning ring and the positioning strip respectively, so as to quickly and accurately position the installation position of the fan blade component, and at the same time quickly align the bolt hole and the threaded hole, improving the installation efficiency and installation accuracy of the fan blade. However, when installing arc-shaped, flat or other special-shaped fan blades, the fixed end of the fan blade cannot be directly inserted into the interior of the impeller bracket, and thus the arc-shaped, flat or other special-shaped fan blades cannot be stably fixed, reducing the use effect.

[0004] Therefore, we propose a split impeller bracket to solve the problems raised above. Content of the Utility Model

[0005] The purpose of the utility model is to provide a split impeller bracket to solve the problem that it is not convenient to directly insert and position the installation of arc-shaped, flat or other special-shaped fan blades proposed in the above background technique.

The upper connection holes are opened at equal angles inside the upper cover plate, the lower connection holes are opened at equal angles inside the lower cover plate, and the positions of the lower connection holes correspond to the positions of the upper connection holes and the installation hole positions of the fan blades.

[0014] Preferably, the upper connection holes and the lower connection holes corresponding to each group of fan blades are distributed in a triangular structure.

[0015] With the design of the above structure, the split design of the upper cover plate and the lower cover plate can clamp and install arc-shaped, flat or other special-shaped fan blades, avoiding the limitations of the plug-in installation method in the common technology, and improving the adaptability of the split blade disc frame to the installation of fan blades.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figure 1 - Figure 6 , the present utility model provides the following technical solutions:

[0032] Embodiment 1: To solve the problem in the prior art that it is not convenient to stably install the arc-shaped, flat or special-shaped fan blades 3, the following solution is thus disclosed. Specifically, as Figures 1-4 shown, a split-type blade disc frame includes an upper cover plate 1 and a lower cover plate 2. The bottom of the upper cover plate 1 is adhesively connected to the lower cover plate 2. Fan blades 3 are installed at equal angles between the lower cover plate 2 and the upper cover plate 1. A motor mounting hole 4 is opened in the inner circle of the upper cover plate 1. A limiting rod 5 is fixedly installed at the bottom of the upper cover plate 1, and the limiting rods 5 are installed at equal angles at the bottom of the upper cover plate 1. A limiting hole 6 is opened inside the lower cover plate 2, and the limiting holes 6 are opened at equal angles inside the lower cover plate 2. The positions of the limiting rods 5 correspond to the positions of the limiting holes 6. Pre-installation holes 7 are opened inside the upper cover plate 1, and the pre-installation holes 7 are opened at equal angles inside the upper cover plate 1. A pre-installation empty space 8 is opened inside the lower cover plate 2, and the pre-installation empty space 8 can prevent the head of the pre-fixed bolt installed in the pre-installation hole 7 from being blocked by the lower cover plate 2. The upper cover plate 1 and the lower cover plate 2 are connected to each other through a positioning connection mechanism. The positioning connection mechanism includes an upper connection hole 9 and a lower connection hole 10. The upper connection holes 9 are opened at equal angles inside the upper cover plate 1, and the lower connection holes 10 are opened at equal angles inside the lower cover plate 2. The positions of the lower connection holes 10 correspond to the positions of the upper connection holes 9 and the mounting hole positions of the fan blades 3. The upper connection holes 9 and the lower connection holes 10 corresponding to each group of fan blades 3 are distributed in a triangular structure;

[0033] The design of the above structure enables the split design of the upper cover plate 1 and the lower cover plate 2 to be clamped and installed from the upper and lower sides of the fixed end of the fan blade 3, which is beneficial to the stable installation of arc-shaped, flat or special-shaped fan blades 3. During installation, first, the fan blade 3 is pre-installed with bolts at the bottom of the upper cover plate 1 through the pre-installation holes 7. Then, after aligning the limiting holes 6 opened inside the lower cover plate 2 with the limiting rods 5 at the bottom of the upper cover plate 1, the lower cover plate 2 and the upper cover plate 1 are fitted and connected. At this time, the head of the pre-installed bolt is just located inside the pre-installation space 8. Then, the bolt penetrates through the upper connection hole 9, the lower connection hole 10 and the installation control at the fixed end of the fan blade 3 to realize the assembly of the upper cover plate 1, the lower cover plate 2 and the fan blade 3.

[0034] Embodiment 2: Another positioning connection method is disclosed in this embodiment. Different from Embodiment 1, it can improve the operation convenience of the connection between the upper cover plate 1 and the lower cover plate 2. Specifically, as Figures 5-6 shown, the positioning connection mechanism includes a positioning rod 11, a fixed seat 12, a threaded rod 13, a limiting seat 14, a limiting plate 15, a clamping plate 16 and a clamping seat 17. A positioning rod 11 is fixedly installed inside the upper connection hole 9. Fixed seats 12 are installed on the outer side of the upper cover plate 1 at equal angles. A threaded rod 13 is rotatably connected inside the fixed seat 12. A clamping plate 16 is sleeved outside the threaded rod 13. The threaded rod 13 and the clamping plate 16 form a threaded telescopic structure. A limiting seat 14 is installed on one side of the clamping plate 16. A limiting plate 15 is slidably connected inside the limiting seat 14. The limiting plate 15 is fixedly connected to the fixed seat 12. Clamping seats 17 are installed on the outer side of the lower cover plate 2 at equal angles. The other side bottom end of the clamping plate 16 is movably clamped and connected to the clamping seat 17;

[0035] The design of the above structure enables the connection between the upper cover plate 1 and the lower cover plate 2 to be further limited by the insertion of the bottom end of the positioning rod 11 into the lower connection hole 10 when connecting the upper cover plate 1 and the lower cover plate 2, improving the connection stability between the upper cover plate 1 and the lower cover plate 2. When fixedly connecting the upper cover plate 1 and the lower cover plate 2, by rotating the threaded rod 13, it rotates inside the fixed seat 12, so that the threaded rod 13 can drive the clamping plate 16 to move inwards and form a clamping with the clamping seat 17 when rotating, realizing the stable connection between the upper cover plate 1 and the lower cover plate 2. By rotating the threaded rod 13 in the reverse direction, the clamping plate 16 can be driven to separate from the clamping seat 17, so as to facilitate the separation of the lower cover plate 2 and the upper cover plate 1 to realize the disassembly and maintenance of the fan blade 3. The sliding connection between the limiting seat 14 and the limiting plate 15 can limit the moving direction of the clamping plate 16.

[0036] Thus, a series of work is completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0037] 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
