Description

Technical Field

[0001] The utility model relates to the technical field of fan lamps, in particular to a blade synchronous gear linkage structure of a fan lamp. Background Art

[0002] The fan lamp is a relatively new type of electrical appliance that combines a ceiling lamp with a fan. The lower end of the fan lamp is provided with a ceiling lamp, and the upper part is provided with a rotatable fan base. A plurality of blades are provided around the circumference of the upper side of the fan base. When the fan base rotates, the blades will unfold due to the centrifugal effect and play the role of a fan. A gear linkage structure is provided between the blades so that the blades can be synchronously linked. The existing gear linkage technology has the risk of tooth skipping after long-term use, making the synchronous linkage function of the blades invalid. Moreover, when the fan base stops rotating, the blades need to be pulled back and folded. At present, a tension spring is installed on the lower side of the blades to reset the blades, which makes the fan lamp thicker and less beautiful. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] like Figure 1-6As shown, the utility model provides a blade synchronous gear linkage structure of a fan lamp, including a fan blade frame plate 1, a plurality of fan blades 2 are arranged around the circumference of the outer side of the fan blade frame plate 1, one end of the fan blade 2 is connected to a gear seat 7, the gear seat 7 is arranged through the fan blade frame plate 1, a limiting wheel 4 is centrally installed on the lower side of the fan blade frame plate 1, a synchronous wheel 5 that can rotate around the center of the fan blade frame plate 1 is arranged between the limiting wheel 4 and the fan blade frame plate 1, a tooth portion 15 is arranged at a position corresponding to the gear seat 7 on the outer edge of the synchronous wheel 5, the tooth portion 15 is meshed with the corresponding synchronous wheel 5, and a coil spring 8 is sleeved on the inner side of the gear seat 7, one end of the coil spring 8 is connected to the gear seat 7, and the other end is connected to the fan blade frame plate 1 to realize the resetting of the fan blade 2.

[0019] Specifically, the gear seat 7 is rotatably connected to the fan blade frame plate 1. After the gear seat 7 passes through the fan blade frame plate 1, it can be detachably connected to the fan blade 2. Figure 4-6 As shown, there are three gear seats 7 and three fan blades 2. When the fan impeller plate 1 is driven by the driving seat 3 in the fan lamp to rotate at high speed, due to the effect of centrifugal force, the three fan blades 2 and the gear seat 7 all rotate, and at the same time drive the synchronous wheel 5 to rotate between the limiting wheel 4 and the fan impeller plate 1. The three gear seats 7 rotate synchronously, and the tooth portion 15 does not need to cover the entire synchronous wheel 5. During installation, the limiting wheel 4 is fixedly connected to the fan impeller plate 1 by screws 6.

[0020] When the speed of the fan blade frame 1 slows down or stops, the gear seat 7 and the fan blades 2 will automatically retract under the action of the coil spring 8.

[0021] Due to the existence of the limiting wheel 4 , the rotation of the synchronous wheel 5 is axially limited, and there will be no problem of tooth jumping between the synchronous wheel 5 and the gear seat 7 .

[0022] In this embodiment, if Figure 6 As shown, a plurality of arcuate through grooves 13 are arranged around the center at positions corresponding to the synchronous wheel 5 on the fan impeller disc 1, and a limiting sliding component 14 passing through the corresponding arcuate through groove 13 is arranged on the synchronous wheel 5. The limiting sliding component 14 slides in the arcuate through groove 13 as the synchronous wheel 5 rotates, and has a guiding and limiting function, and can also limit the stroke of the synchronous wheel 5.

[0023] In this embodiment, if Figure 3 As shown, a circle of protrusions 9 are arranged on the side of the limiting wheel 4 facing the synchronous wheel 5 at positions corresponding to the synchronous wheel 5, and a groove 10 corresponding to the protrusions 9 is arranged on the side of the synchronous wheel 5 facing the limiting wheel 4. The protrusions 9 and the grooves 10 can improve the strength of the synchronous wheel 5 and the limiting wheel 4. At the same time, when the synchronous wheel 5 rotates, the protrusions 9 and the grooves 10 cooperate to achieve radial limiting.

[0024] In this embodiment, if Figure 3 As shown, the portion of the gear seat 7 that meshes with the synchronous wheel 5 is provided with a limiting outer edge 11 extending outward from the edge, and the limiting outer edge 11 extends to the lower side of the edge of the synchronous wheel 5, which can further prevent tooth jumping between the gear seat 7 and the synchronous wheel 5.

[0025] In this embodiment, a plurality of coil spring connecting plates 12 are arranged on the side of the gear seat 7 on the fan impeller plate 1, one end of the coil spring 8 is connected to the coil spring connecting plate 12, and the coil spring 8 can select a coil spring connecting plate 12 to be connected to adjust the resistance.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0028] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
