Description

Technical Field

[0001] This utility model relates to the field of wrought iron crafts, specifically a wind-driven wrought iron craft ornament. Background Technology

[0002] Pneumatic wrought iron ornaments are handicrafts that use wind power to drive metal display pieces to produce regular or random movements. The display pieces are equipped with movable decorations or sound-emitting mechanisms, thus creating a flowing visual effect and sound when rotating.

[0003] In existing wind-driven wrought iron ornaments, the ornaments usually rotate by receiving wind power. However, when the ornaments are placed in semi-enclosed areas such as balconies and windowsills, it is difficult for them to receive wind power and rotate. Furthermore, because the ornaments do not have a stopping mechanism, the ornaments will continue to rotate even when they are not needed, making it difficult to achieve still viewing. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a wind-driven iron craft ornament, comprising a wind-driven component and a display component. The wind-driven component and the display component are rotatably connected to a wind-driven support and a display support, respectively. The wind-driven component includes several blades, and the wind-driven component and the display component are connected by a transmission mechanism, allowing the wind-driven component to transmit the received wind power to the display component. A fixed shaft is fixedly provided on the display support. The display component includes a central disc portion with a first opening in the center. The display component rotatably engages with the fixed shaft through the first opening. Side slots are provided on both sides of the fixed shaft, making the fixed shaft flat in a cross-section perpendicular to the axis. A first latch extends radially from the first opening of the disc portion, and the display component engages with the side slots through the first latch, thereby restricting the degree of freedom of rotation of the display component around the axis of the fixed shaft. The display component has a fitting mechanism inside for engaging with the first opening of the disc portion to form a complete circumferential hole structure.

[0005] Furthermore, the top and bottom of the side slot are provided with top contacts, and the top contacts retain a fixed-axis curved circumferential shape.

[0006] Furthermore, the fitting mechanism includes a frame mounted on the display piece, the frame having a second opening that is rotatably fitted onto a fixed axis, and the second opening extending radially along the disc having a second latch; the frame, by rotating the second latch to offset it from the first latch, allows the first and second openings to fit together to form a complete circumferential hole structure.

[0007] Furthermore, the fitting mechanism also includes a positioning rod slidably mounted in the frame and a spring nested between the positioning rod and the frame. A positioning groove is provided on the disc at one end of the display piece. The spring provides elastic force to drive the tail of the positioning rod into the positioning groove. The positioning rod, which is locked into the positioning groove, restricts the degree of freedom of rotation between the frame and the display piece around a fixed axis.

[0008] Furthermore, the disc is provided with an arc-shaped movable groove, the head of the positioning rod passes through the movable groove to the outside of the display piece, and the head of the positioning rod is equipped with a pull handle; the movable groove has at least two positioning grooves within the projection range on the opposite side of the disc.

[0009] Furthermore, the transmission mechanism includes a driving gear and a driven gear, a transmission shaft is provided at the rotation center of the pneumatic component, the end of the transmission shaft is connected to the driving gear, and a driven gear is installed at the center of the disc of the display component and meshes with the driving gear.

[0010] Furthermore, a limiting member is provided on the disc along the length direction of the first slot. The horizontal height of the display piece, which tends to engage with the side slot, decreases so that the limiting member abuts against the drive gear, thereby restricting the degree of freedom of rotation of the drive gear.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention separates the wind-driven pneumatic component from the display component, allowing the display component to be started and stopped independently. The display component has a first latch on its first opening and a side groove on its fixed shaft to narrow the fixed shaft. By having the first latch of the display component sink into the side groove, the display component is disconnected from the pneumatic component and its rotation is restricted. This allows the display component to stop rotating while still meeting some of the display requirements.

[0013] Furthermore, this utility model features a fitting mechanism on the inner side of the display piece to accommodate it. The second opening of the display stand engages with the first opening of the display piece to form a complete circumferential hole structure, allowing the display piece to rotate smoothly on the fixed axis. Simultaneously, a second latch is provided on the second opening. After rotating the display stand, the second latch aligns with the first latch, allowing the display piece to be snapped into the fixed axis for static viewing when needed.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0024] Examples, such as Figures 1-6As shown: This utility model provides a wind-driven iron craft ornament, the structure of which includes a base 1 and an independent wind-driven component 2 and display component 5 mounted on the base 1. The wind-driven component 2 includes several blades for receiving wind power to rotate. The wind-driven component 2 and display component 5 are rotatably connected to the wind-driven support 3 and the display support 7, respectively. The wind-driven component 2 and display component 5 are connected by a transmission mechanism 6 so that the wind-driven component 2 transmits the wind power it receives to the display component 5. Specifically, the transmission mechanism 6 includes a driving gear 61 and a driven gear 62. A transmission shaft 4 is provided at the rotation center of the wind-driven component 2. The transmission shaft is rotatably engaged with the wind-driven support 3. The end of the transmission shaft 4 is connected to the driving gear 61. The center of the disc 51 of the display component 5 is equipped with a driven gear 62 and meshes with the driving gear 61. The rotation of the wind-driven component 2 drives the driving gear 61 to rotate through the transmission shaft 4. The driving gear 61 drives the driven gear 62 to rotate, thereby causing the display component 5 connected to the driven gear 62 to rotate.

[0025] As those skilled in the art will know, in this embodiment the transmission shaft 4 is a rigid shaft, but depending on actual needs, the transmission shaft 4 can also be a flexible shaft, so that the pneumatic component 2 can be arranged in a more distant or wider angle, such as extending out of the windowsill.

[0026] It should be noted that (number of teeth of driven gear 62 / number of teeth of driving gear 61) > 2, that is, the gear ratio of driven gear 62 to driving gear 61 is greater than 2, so as to prevent the display piece 5 from rotating too fast when the pneumatic component 2 is driven by the wind.

[0027] Specifically, a fixed shaft 71 is fixedly provided on the display bracket 7, and the display component 5 includes a central disc 51. A first through-hole 52 is provided in the middle of the disc 51, and the display component 5 is rotatably fitted onto the fixed shaft 71 through the first through-hole 52. At the same time, side slots 711 are provided on both sides of the fixed shaft 71. The side slots 711 on both sides make the fixed shaft 71 flat in a cross section perpendicular to the axis. Top contacts 712 are provided at the top and bottom of the side slots 711. The top contacts 712 retain the curved circumferential shape of the fixed shaft 71. The display component 5 is placed on the fixed shaft 71 so that the first through-hole 52 is rotatably fitted onto the top contact 712 at the top.

[0028] In conjunction with this, the first opening 52 extends radially along the disc portion 51 and is provided with a first latch 53. The width of the first latch 53 is greater than the distance between the two side latches 711. The display piece 5 engages with the side latches 711 through the first latch 53, thereby sinking and embedding itself into the fixed axis 71, and restricting the degree of freedom of the display piece 5 to rotate around the axis of the fixed axis 71.

[0029] In order to ensure the normal rotation and use of the display piece 5, the display piece 5 is provided with a fitting mechanism 8 for cooperating with the first opening 52 of the disc 51 to form a complete circumferential hole structure. Specifically, the fitting mechanism 8 includes a swing frame 81 mounted on the display piece 5. The swing frame 81 is provided with a second opening 811. The second opening 811 is rotatably fitted on the fixed shaft 71, just like the first opening 52. The second opening 811 is provided with a second latch 812 extending radially along the disc 51, just like the first latch 53. The swing frame 81 and the inner side of the display piece 5 are detachably fixed. The swing frame 81 rotates the second latch 812 to offset the first latch 53 so that the first opening 52 and the second opening 811 cooperate to form a complete circumferential hole structure.

[0030] In conjunction with this, the fitting mechanism 8 also includes a positioning rod 82 slidably mounted in the frame 81 and a spring 83 nested between the positioning rod 82 and the frame 81. The disc portion 51 at one end of the display piece 5 is provided with a positioning groove 54. The spring 83 provides the elastic force to drive the tail of the positioning rod 82 into the positioning groove 54. The positioning rod 82, which is inserted into the positioning groove 54, restricts the degree of freedom of rotation between the frame 81 and the display piece 5 around the fixed axis 71, thereby fixing the frame 81 and the display piece 5.

[0031] Correspondingly, the disc 51 is provided with an arc-shaped movable groove 55. The head of the positioning rod 82 passes through the movable groove 55 to the outside of the display piece 5. The head of the positioning rod 82 is equipped with a pull handle 84. By pulling the pull handle 84 outward, a pulling force is applied to the positioning rod 82 to overcome the elastic force of the spring 83, so that the positioning rod 82 is disengaged from the movable groove 55. The movable groove 55 is provided with at least two positioning grooves 54 within the projection range on the opposite disc 51. One corresponds to the position where the second latch 812 coincides with the first latch 53, while the rest correspond to the positions where the second latch 812 and the first latch 53 are offset.

[0032] In summary, during implementation, the pull handle 84 passing through the movable slot 55 is pulled out to disengage the positioning rod 82 from the movable slot 55. Then, the pull handle 84 is rotated to rotate the swing arm, causing the second latch 812 to misalign with the first latch 53. This allows the first opening 52 and the second opening 811 to mate and form a complete circumferential hole structure, allowing the display piece 5 to rotate on the fixed axis 71 under the influence of the pneumatic component 2 for pneumatic viewing. When the display piece 5 is needed for display purposes but not for rotation, the pull handle 84 passing through the movable slot 55 is pulled out to move the positioning rod 82 to the opposite position. The second bayonet 812 and the first bayonet 53 are aligned in the positioning groove 54. The second bayonet 812 and the first bayonet 53 are aligned. Then the display piece 5 is rotated to the angle where the first bayonet 53 is above. At this time, the first bayonet 53 can sink down and embed into the fixed shaft 71 along the side slot 711, restricting the degree of freedom of rotation of the display piece 5 around the axis of the fixed shaft 71. At the same time, as the position of the display piece 5 decreases, the driven gear 62 on the display piece 5 disengages from the driving gear 61, so it is not driven by the wind-driven component 2 and can be viewed statically.

[0033] In this embodiment, in addition to this, a limiting member 56 is provided on the disc 51 along the length direction of the first latch 53. The display piece 5, which tends to engage with the side latch 711, i.e. the display piece 5 whose horizontal height is about to decrease, is lowered by the limiting member 56 sinking and embedding into the fixed shaft 71, so that the limiting member 56 provided on the display piece 5 decreases and abuts against the drive gear 61. The limiting member 56 adopts a structure with meshing teeth to mesh with the teeth of the drive gear 61, thereby restricting the degree of freedom of rotation of the drive gear 61, thereby preventing the pneumatic component 2 from rotating.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
