Description

Technical fields:

[0001] This utility model belongs to the field of decorative lighting technology, and specifically refers to a lighting fixture. Background technology:

[0002] Spherical light fixtures consist of a spherical frame and strings of lights wrapped around it. While they offer good decorative effects, they have the following disadvantages during transportation and storage:

[0003] Existing spherical lamps have fixed spherical frames that cannot be folded or compressed, resulting in low space utilization during transportation and storage. Due to their large size, the quantity transported at one time is limited, increasing logistics costs; and they occupy a lot of warehouse space, especially affecting inventory management efficiency when storing large quantities.

[0004] Currently, some spherical lamps on the market are attempting to use detachable frames, but the assembly process is cumbersome and may affect structural stability. In addition, although flexible frames (such as elastic materials) can be compressed, it is difficult to maintain the regularity of the spherical structure, affecting the final lighting effect. Summary of the Invention:

[0005] The purpose of this invention is to provide a collapsible lamp to reduce logistics and warehousing costs.

[0006] This utility model is implemented as follows:

[0007] A lighting fixture includes a fixed frame and a movable frame. The fixed frame is in a closed-loop shape, with an upper support plate and a lower support plate symmetrically fixed at its top and bottom, respectively. The outer circumference of the upper and lower support plates has several radially arranged grooves, with a through hole at the inner end of each groove. The top and bottom of the fixed frame are respectively aligned with the diameters of the upper and lower support plates. The upper and lower ends of the movable frame are respectively formed with an upper rotating shaft and a lower rotating shaft. The upper rotating shaft is inserted into the through hole of the upper support plate, and the lower rotating shaft passes through the through hole of the lower support plate. Independent light strings are wound around the fixed frame and the movable frame, respectively. The light strings are connected in series or parallel to a switch control box. When the movable frame is retracted, it moves towards the corresponding side of the fixed frame around the upper and lower rotating shafts to form a flat structure. When the movable frame is opened, it is limited by grooves.

[0008] In one of the above-mentioned lighting fixtures, the top of the fixed frame is welded and fixed to the upper plane of the upper support plate, and the bottom of the fixed frame is welded and fixed to the bottom surface of the lower support plate.

[0009] In one of the aforementioned lighting fixtures, a hanging ring is provided at the top of the fixed frame.

[0010] In one of the aforementioned lighting fixtures, the bottom of the hanging ring is welded and fixed to the top of the fixed frame.

[0011] In one of the above-mentioned lighting fixtures, the fixed frame is a circular frame, a Christmas tree-shaped frame, or a five-pointed star-shaped frame structure; correspondingly, the movable frame is a semi-circular frame, a semi-Christmas tree-shaped frame, or a semi-five-pointed star-shaped frame structure.

[0012] In one of the aforementioned lighting fixtures, the control box includes a box body and a box cover. The box body contains a battery compartment and a control circuit board compartment. The battery is located in the battery compartment, and the control circuit board is located in the control circuit board compartment. The control circuit board has a push-button switch for controlling the lighting status of the light string. A cover is provided above the control circuit board compartment, and the cover has a clearance hole for the push-button switch to pass through. The box cover has a resilient button that can press the push-button switch.

[0013] In one of the above-mentioned lighting fixtures, the switch control circuit board compartment is provided with two or more positioning posts with insertion holes, the control circuit board is provided with positioning holes that are inserted into the corresponding positioning posts, the bottom surface of the cover is provided with insertion posts, and the cover is detachably fixed above the control circuit board compartment by being inserted into the insertion holes of the positioning posts through the insertion posts.

[0014] The outstanding advantages of this utility model compared to the prior art are:

[0015] 1. In use, the movable frame unfolds, forming a three-dimensional shape with the fixed frame, such as a sphere, a three-dimensional Christmas tree, or a three-dimensional five-pointed star, to suit different occasions and achieve a decorative effect. When folded, the movable frame is brought together with the corresponding sides of the fixed frame to form a flat structure. At this time, the volume is significantly reduced, increasing the quantity transported in a single shipment and increasing the quantity stored in the same space, effectively reducing transportation and storage costs.

[0016] 2. The structure of this utility model, in which the fixed frame is fixedly connected to the upper and lower support plates, provides a rigid support frame for the lamp, ensuring the stability of the overall structure. In particular, it can withstand the weight of the movable frame and the light string when unfolded, preventing deformation. The fixed frame also provides a convergence reference for the retraction of the movable frame.

[0017] 3. The battery and control circuit board of this utility model are set up separately to avoid mutual interference, facilitate individual battery replacement or circuit repair, and improve maintenance convenience. Attached image description:

Detailed implementation method:

[0024] The present invention will be further described below with reference to specific embodiments:

[0025] like Figures 1-5 As shown, this utility model provides a lamp, which includes a fixed frame 1 and a movable frame 2. The fixed frame 1 is in the shape of a closed ring. An upper support plate 3 and a lower support plate 4 are symmetrically fixed at the top and bottom of the fixed frame 1, respectively. The outer circumference of the upper support plate 3 and the lower support plate 4 is distributed with a plurality of radially arranged grooves 5. A through hole 6 is provided at the inner end of each groove 5. The top and bottom of the fixed frame 1 are respectively arranged along the diameter of the upper support plate 3 and the lower support plate 4. The upper and lower ends of the movable frame 2 are respectively formed with an upper rotating shaft 7 and a lower rotating shaft 8. The upper rotating shaft 7 is inserted into the upper support plate 2. The lower pivot 8 passes through the through hole 6 of the support plate 3 and the lower pivot 8 passes through the through hole 6 of the lower support plate 4. Independent light strings 9 are wound on the fixed frame 1 and the movable frame 2 respectively. The light strings 9 are connected to the switch control box 10 after being connected in series or in parallel. When the movable frame 2 is closed, it moves towards the corresponding side of the fixed frame 1 around the upper pivot 7 and the lower pivot 8 to form a flat structure. When the movable frame 2 is opened, it is limited by the groove 5. The groove 5 holds the movable frame 2 to maintain a specific angle, thereby fixing the unfolded shape of the lamp (such as spherical or polyhedral) and ensuring the uniformity and aesthetics of the lighting.

[0026] As can be seen from the above, when this utility model is used, the movable frame 2 is unfolded, forming a three-dimensional shape together with the fixed frame 1, such as a sphere, a three-dimensional Christmas tree, or a three-dimensional five-pointed star, to suit different occasions and achieve a decorative effect. When folded up, the movable frame 2 is brought together with the corresponding sides of the fixed frame 1 to form a flat structure. At this time, the volume is significantly reduced, which can increase the quantity transported in a single shipment and increase the quantity stored in the same space, effectively reducing transportation and storage costs.

[0027] Furthermore, the structure in which the fixed frame 1 is fixedly connected to the upper support plate 3 and the lower support plate 4 provides a rigid support frame for the lamp, ensuring the stability of the overall structure. In particular, it can withstand the weight of the movable frame and the light string 9 in the unfolded state, preventing deformation. The fixed frame 1 also provides a convergence reference for the folding of the movable frame 2.

[0028] Furthermore, the top of the fixed frame 1 of this utility model is welded and fixed to the upper plane of the upper support plate 3, and the bottom of the fixed frame 1 is welded and fixed to the bottom surface of the lower support plate 4.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, to facilitate the hanging of this utility model, a hanging ring 11 is provided at the top of the fixed frame 1. In this embodiment, the bottom of the hanging ring 11 is welded and fixed to the top of the fixed frame 1. Of course, the hanging ring 11 can also be threaded to the fixed frame 1 and the upper support plate 3. Specifically, a stud is provided on the hanging ring 11, and mounting holes are provided on the fixed frame 1 and the upper support plate 3. The stud passes through the mounting holes and is locked and fixed by a nut.

[0030] As can be seen from the above, this utility model has a variety of shapes. Specifically, the fixed frame 1 is a circular frame, a Christmas tree-shaped frame, or a five-pointed star-shaped frame structure; correspondingly, the movable frame 2 is a semi-circular frame, a semi-Christmas tree-shaped frame, or a semi-five-pointed star-shaped frame structure.

[0031] Furthermore, such as Figure 1 and Figure 5As shown, the control box 10 of this utility model includes a box body 12 and a box cover 13. A battery compartment 14 and a control circuit board compartment are disposed within the box body 12. A battery 15 is disposed within the battery compartment 14, and the control circuit board is disposed within the control circuit board compartment. The control circuit board has a push-button switch 16 that controls the lighting state of the light string 9. A cover 17 is disposed above the control circuit board compartment, and a clearance hole 18 is provided on the cover 17 to allow the push-button switch 16 to pass through. A resilient button 19 is provided on the box cover 13, which can press the push-button switch 16. The battery 15 and the circuit board are disposed in separate compartments to avoid mutual interference, facilitate individual replacement of the battery 15 or repair of the circuit, and improve maintenance convenience. Centralized control of the lighting state of the light string 9 (such as switching on / off, mode switching) via the circuit board simplifies wiring connections and improves reliability.

[0032] Furthermore, the control circuit board compartment is equipped with two or more positioning posts with insertion holes. The control circuit board has positioning holes that insert into the corresponding positioning posts. The bottom surface of the cover 17 is provided with insertion posts. The cover 17 is detachably fixed above the control circuit board compartment by inserting into the insertion holes of the positioning posts via the insertion posts. The cover 17 adopts a plug-in connection, which eliminates the need for tools for disassembly and assembly, facilitating the maintenance or replacement of the control circuit board and simplifying the assembly process.

[0033] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
