[0002] With the improvement of living standards, various decorative lighting fixtures are increasingly widely used in commercial spaces, home environments and celebrations. Light strings, light strips and other lighting fixtures are usually composed of lights and wires and generally do not have the ability to support themselves. When using them, decorative brackets are used to support the lighting fixtures.

[0003] Traditional lamp decoration brackets typically employ a fixed structure, such as the LED lamp bracket disclosed in Chinese patent CN203880639U. Existing lamp decoration brackets have a fixed volume, making it impossible to arbitrarily change the shape and size of the bracket, which is inconvenient for storage and transportation. Although some brackets can be reduced in size and changed in shape, they often rely on cumbersome manual assembly steps. For users, not only are there many related parts that are easy to lose, but this manual assembly also requires a certain level of dexterity, making it inconvenient to use and resulting in a poor product experience. In view of this, the inventor has made a new invention. Utility Model Content

Detailed Implementation

[0031] The following is in conjunction with the appendix Figures 1 to 10 This utility model will be described in detail.

[0032] Embodiment 1: A decorative bracket with adjustable volume according to the present invention includes a first positioning component 1 and a second positioning component 2, and a skeleton component 3 with elastic deformation. One end of the skeleton component 3 is movably connected to the first positioning component 1, and the other end is movably connected to the second positioning component 2. The first positioning component 1 has an adjusting member 11, and the second positioning component 2 has a through hole 21. One end of the adjusting member 11 is connected to the inner side of the first positioning component 1. It should be emphasized that the inner side described here refers to the connection relationship between one end of the adjusting member 11 and the top surface of the first positioning component 1. Of course, one end of the adjusting member 11 can also pass through the inner side from the outside, which has the same connection effect, such as the connecting strap 13, pull rope 14, support rod 16, etc., described in the later embodiments. The other end of the adjusting member 11 passes through the through hole 21 to form a control end 12; it also includes a limiting component 4, which can limit the control end 12 of the adjusting member 11; the skeleton component 3 drives the first positioning component 1 and the second positioning component 2 to separate to reduce the volume of the decorative bracket, where separation here only refers to moving the first positioning component 1 and the second positioning component 2 away from each other in relative position. The adjusting member 11 controls the relative distance between the first positioning component 1 and the second positioning component 2. When needed, i.e. when the skeleton component 3 needs to deform, the relative positions of the first positioning component 1 and the second positioning component 2 change. Specifically, when the relative distance between the first positioning component 1 and the second positioning component 2 is reduced by the adjusting component 11, the lateral volume of the decorative bracket gradually increases. When deformed to the desired shape and size, the control end is fixed by the limiting component to prevent the relative distance between the first positioning component 1 and the second positioning component 2 from changing. When packaging, transportation, or storage is required, the fixing of the control end by the limiting component is released. After the control end is unrestricted, the skeleton component 3 uses elastic deformation to drive the first positioning component 1 and the second positioning component 2 to separate to reduce the volume of the decorative bracket. When the relative distance between the first positioning component 1 and the second positioning component 2 is increased by the adjusting component 11, the lateral volume of the decorative bracket decreases. According to the above structure of this utility model, the decorative bracket can finally form a bracket that is close to the shape of a cylinder. At this time, compared with the volume when in use, the space volume has been greatly reduced, which is beneficial for packaging, transportation, and storage, reduces logistics costs, and is also extremely convenient to use.

[0033] See Figure 7 As shown, when the limiting component 4 does not restrict the control end 12 of the adjusting component 11, the elasticity of the frame component 3 drives the first positioning component 1 and the second positioning component 2 to reach the maximum relative distance. At this time, the decorative bracket is approximately cylindrical, which facilitates storage, transportation, and handling. See also Figure 6 and Figure 1As shown, when the relative distance between the first positioning component 1 and the second positioning component 2 decreases, the skeleton component 3 deforms and expands outward. At this time, the decorative bracket deforms from an approximately cylindrical shape to an approximately lantern shape. The control end 12 of the adjusting component 11 is restricted by the limiting component 4 to limit the relative distance between the first positioning component 1 and the second positioning component 2, thereby shaping the decorative bracket. The operation is simple and quick.

[0034] The skeleton assembly 3 is provided with multiple supports 31, which are made of elastic material, such as plastic with a certain degree of toughness, and most preferably, elastic metal material, such as spring steel. The lower end of the support 31 is movably connected to the first positioning assembly 1, and the upper end of the support 31 is movably connected to the second positioning assembly 2. Ideally, the support 31 can be pre-bent outward in a certain guiding arc, so that the skeleton assembly 3 can deform along this guiding arc during deformation. Since the support 31 is made of elastic material, it can be easily placed in a storage bag by applying external force during storage without affecting its storage function. When the elasticity of the skeleton assembly 3 drives the first positioning assembly 1 and the second positioning assembly 2 to reach their maximum relative distance, the shape of the support 31 is close to vertical but still has a certain guiding arc. This shape facilitates the stable outward expansion of the support 31 in a predetermined direction when the skeleton assembly 3 deforms to increase its volume, making operation easier. The use of spring steel for the support rib 31, with its circular cross-section, is a preferred choice in this invention. This material possesses high elastic limit, high fatigue strength, good toughness and plasticity, which improves the elastic deformation stability of the frame assembly 3, thereby extending the service life of the decorative bracket. When the elasticity of the frame assembly 3 drives the first positioning component 1 and the second positioning component 2 to reach their maximum relative distance, the shape of the support rib 31 is nearly vertical but still has a certain curvature. This shape allows the support rib 31 to stably expand outwards when the frame assembly 3 deforms to increase its volume, which is highly beneficial for the product's use.

[0035] In the specific deformable structure of the skeleton component 3, the skeleton component 3 is provided with multiple support bones 31, which are made of elastic material. Each support bone 31 has a connecting ring 32 at both ends. The first positioning component 1 and the second positioning component 2 are provided with positioning elements 23 that pass through the holes of the connecting rings 32. The positioning element 23 is preferably an annular body, which is fixedly installed in the first positioning component 1 or the second positioning component 2. The first positioning component 1 and the second positioning component 2 are also provided with several guide openings 22. The two ends of the support bones 31 respectively pass through the guide openings 22 and extend into the interior of the first positioning component 1 and the second positioning component 2. The positioning element 23 connects to the connecting rings 32 at one end of all the support bones 31, so that the two ends of the support bones 31 are fitted into the interior of the first positioning component 1 and the second positioning component 2. The guide openings 22 extend from the side wall of the first positioning component 1 to the inner side of the first positioning component 1, forming an L-shape. When the skeleton component 3 deforms, the support bones 31 can move along the guide openings 22, making the deformation process of the skeleton component 3 smooth and fluid. The width of the guide opening 22 is slightly larger than the diameter of the support bone 31, which limits the left and right swing amplitude of the support bone 31, reduces the looseness of the skeleton component 3, and stabilizes the deformable structure.

[0036] The other end of the adjusting member 11 passes through the through hole 21 to form a control end 12, and the limiting component 4 can limit the control end 12 of the adjusting member 11, as in embodiment one. Figure 3 As shown, the adjusting component 11 includes a connecting strap 13. One end of the connecting strap 13 is connected to the inner side of the first positioning component 1, and the other end of the connecting strap 13 is the control end 12. The limiting component 4 is provided with a limiting block 41 fixedly connected to the second positioning component 2. The control end 12 can be wrapped around the limiting block 41 to limit the relative distance between the first positioning component 1 and the second positioning component 2. The connecting strap 13 is made of materials such as nylon or synthetic fibers, and needs to be flexible and have high strength. The limiting block 41 is an L-shaped inverted shape, forming a recess between the limiting block 41 and the second positioning component 2. The control end 12 of the connecting strap 13 is wrapped around the limiting block 41, so that the maximum relative distance between the second positioning component 2 and the first positioning component 1 is limited. At this time, the skeleton component 3 elastically drives the second positioning component 2. Without other external forces, the relative distance between the second positioning component 2 and the first positioning component 1 is fixed, so that the decorative bracket completes the deformation and is fixed in this shape. The control end 12 can be locked and unlocked simply by wrapping, which is quick and convenient to operate. The use of a connecting strap makes it easier to adjust the distance and has a better cost.

[0037] Example 2, as Figure 4As shown, the adjusting component 11 includes a pull rope 14, one end of which is connected to the inner side of the first positioning component 1, and the other end of which is the control end 12. The control end 12 is provided with a plurality of sequentially arranged limiting protrusions 15, and the limiting component 4 is provided with an elastic buckle 42 for limiting the position of the limiting protrusions 15. If the pull rope 14 is made of nylon or synthetic fiber, the limiting protrusions 15 in this solution can be formed by knotting the rope itself; if the pull rope 14 is made of iron wire or steel wire, the limiting protrusions 15 in this solution are formed of metal or plastic, and the position of the limiting protrusions 15 is limited by the elastic buckle 42 to fix the second positioning component 2, so that the decorative bracket can complete the deformation and fix the shape.

[0038] More specifically, the elastic buckle 42 includes a limiting frame 421 fixed to the second positioning component 2 and a plate buckle 422 movably connected to the limiting frame 421. A return spring 423 is provided between the plate buckle 422 and the limiting frame 421, and a limiting hole 424 is provided in the middle of the plate buckle 422. By pressing the plate buckle 422, the limiting hole 424 is aligned with the through hole 21, and the control end 12 of the pull rope 14 passes through the limiting hole 424. Then, the plate buckle 422 is released. Under the elastic action of the return spring 423, the plate buckle 422 will press against the other side of the limiting frame 421, and the limiting hole 424 and the through hole 21 will be misaligned. The plate buckle 422 and the limiting frame 421 cooperate to bite the stretching control end 12, so that the limiting protrusion 15 cannot pass through the through hole 21, thereby limiting the maximum relative distance between the first positioning component 1 and the second positioning component 2. By setting the spacing between the limiting protrusions 15, the decorative bracket can be quickly deformed into a preset shape.

[0039] Example 3, as Figure 5 As shown, the adjusting component 11 includes a support rod 16, one end of which is connected to the inner side of the first positioning component 1, and the other end of which is the control end 12. The control end 12 is provided with a threaded portion 17, and the limiting component 4 is provided with an adjusting nut 43 connected to the threaded portion 17. The outer diameter of the adjusting nut 43 is larger than the diameter of the through hole 21. The frame component 3 drives the second positioning component 2 to abut against the adjusting nut 43. The relative distance between the second positioning component 2 and the first positioning component 1 can be slowly adjusted by rotating the adjusting nut 43, so as to fine-tune the shape of the decorative bracket.

[0040] The control end 12 of the support rod 16 extends and is provided with a mounting part 18. The support rod 16 can improve the support strength and installation stability of the decorative bracket, and the mounting part 18 can be used to install the decorative bracket on the ceiling, wall panel, etc., increasing the application scenarios of this utility model.

[0041] The first positioning component 1 and the second positioning component 2 have circular cross-sections. The guide openings 22 are evenly distributed around the edges of the first positioning component 1 and the second positioning component 2, so that the support bones 31 of the skeleton component 3 are evenly distributed.

[0042] The size difference between the first positioning component 1 and the second positioning component 2 is usually not significant, so that the decorative bracket can be shaped into an approximate lantern shape. The sizes of the first positioning component 1 and the second positioning component 2 can also be significantly different; for example, the diameter of the second positioning component 2 can be twice or more than that of the first positioning component 1, so that the decorative bracket can be shaped into an approximate birdcage shape.

[0043] This utility model also provides a decorative lamp with a changeable shape, including the aforementioned decorative bracket, a control device 5, and multiple light strips 6 electrically connected to the control device 5. The light strips 6 are arranged along the axial direction of the decorative bracket and connected to the frame assembly 3 of the decorative bracket. Since the frame assembly 3 has multiple supports 31, the light strips 6 are extended along the supports 31 to the lower end. The light strips 6 can be connected in different ways according to the shape of the supports 31, but a simpler method is to use thin ropes to tie the light strips 6 along the supports 31, thereby forming a decorative lamp with lighting function. In use, the lamp is turned on and hung, and the control device 5 is used to control the lamp in different ways.

[0044] To control the multiple installed light strips 6, the control device 5 can be installed inside the second positioning component 2 or near the second positioning component 2. The number of light strips 6 is the same as that of the support ribs 31. Each light strip 6 is connected to a single support rib 31. Since the support rib 31 can deform to any arc, its length will not change. Therefore, when the volume of the decorative bracket changes, the volume of the decorative lamp will also change accordingly, allowing the lamp to be unfolded for lighting and decoration, thus improving its aesthetics.

[0045] The light strip 6 includes multiple LED beads 62 and wire assemblies 61 connecting the LED beads 62, such as... Figure 9 As shown, the wire assembly 61 consists of three strands of wire and an insulating layer 65 that wraps the three strands of wire. The three strands of wire include two power wires 63 and one electrical signal control wire 64. Users can use remote control or other means to control the flashing frequency, light color, and character formation of the LED beads 62 through the electrical signal control wire 64, which can help improve the lighting atmosphere.

[0046] The control device 5 is equipped with an integrated circuit board 51, which is connected to a power supply 52. ​​Multiple light strips 6 are electrically connected to the integrated circuit board 51. According to the usage scenario of decorative lighting fixtures, the power supply 52 can be directly connected to a power source using an electrical plug; the power supply 52 can be directly plugged into a power socket. Alternatively, the power supply 52 can also be... (See...) Figure 10The method shown is to power the integrated circuit board 51 with dry cell batteries, which makes it more convenient to use.

[0047] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this invention. The content of this specification should not be construed as a limitation of this utility model.
