Description

Technical Field

[0001] This utility model relates to the field of lantern technology, and in particular to a deformable lantern. Background Technology

[0002] Lanterns, as items that combine traditional cultural connotations with decorative functions, are widely used in various scenarios such as festivals, landscape arrangements, and interior decoration. As people's demands for decorative diversity and ease of use increase, traditional fixed-form lanterns can no longer meet market demands—their fixed and non-adjustable structure, monotonous decorative style, and large overall size cause many inconveniences in packaging, transportation, and storage.

[0003] To address the aforementioned issues, deformable or detachable lantern designs have emerged in related technical fields. For example, Chinese utility model patent CN207500956U discloses a landscape lantern that can automatically deform. It uses a motor, lead screw, and gear transmission assembly to drive the upper support to move up and down, thereby compressing and deforming the spoke springs to adjust the size and shape of the lantern. However, this type of automatically deformable lantern has significant drawbacks: relying on complex mechanical drive structures such as motors, lead screws, and gears not only results in high manufacturing costs and cumbersome assembly processes, but also makes the mechanical components prone to wear, jamming, and other malfunctions over long-term use, affecting its lifespan. Furthermore, the presence of the mechanical drive structure increases the overall weight of the lantern, making installation and maintenance inconvenient and unsuitable for low-cost, lightweight applications.

[0004] Therefore, there is an urgent need for a deformable lantern that is simple in structure, flexible in deformation, easy to assemble and disassemble, and inexpensive, in order to make up for the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this invention is to provide a deformable lantern to solve the problems mentioned in the background art.

[0006] The above-mentioned objective of this utility model is achieved through the following technical solution: a deformable lantern, comprising: The inner cylinder has at least one of its upper and lower ends distributed with a plurality of first bending pieces. Each first bending piece has at least one pre-fold crease and a first insertion hole is provided at the pre-fold crease. The outer cylinder is fitted onto the outside of the inner cylinder, and the body of the outer cylinder is composed of multiple cylindrical plates that can undergo elastic bending deformation distributed circumferentially; The outer cylinder is provided with a second bending piece at its end. The second bending piece is distributed on the outside of the first bending piece. A second insertion hole is provided at the bend between the second bending piece and the outer cylinder. An end connecting plate has several plug-in pieces distributed on it. The plug-in pieces can be simultaneously inserted into the second plug hole and the first plug hole at the corresponding positions to position the inner cylinder and the outer cylinder. End caps are fitted onto the upper and lower ends of the outer cylinder, respectively.

[0007] Preferably, the first bending piece is distributed at both the upper and lower ends of the inner cylinder, and the second bending piece is distributed at both the upper and lower ends of the outer cylinder.

[0008] Preferably, the first bending piece has two pre-fold lines, which are distributed at intervals along the top and bottom, with one of the pre-fold lines located at the connection between the first bending piece and the inner cylinder.

[0009] Preferably, the length of the outer cylinder after the second bending piece is bent in its natural state is equal to the length of the inner cylinder after the first bending piece is bent along the outermost pre-crease.

[0010] Preferably, the outer cylinder includes an upper sleeve and a lower sleeve distributed vertically, and a cylindrical plate connected between the upper sleeve and the lower sleeve, wherein the cylindrical plate is evenly distributed circumferentially.

[0011] Preferably, the cross-sectional shapes of the inner and outer cylinders are circular or regular polygonal, and the shape of the end connecting plate matches the cross-sectional shape of the outer cylinder.

[0012] Preferably, the width of the connector increases from the end towards the bend between the connector and the end connecting plate, and the connector has a locking slot near the bend.

[0013] Preferably, the end cap is provided with a first locking through hole, and the upper and lower ends of the inner cylinder and the outer cylinder are provided with a second locking through hole and a third locking through hole, respectively. The first locking through hole, the second locking through hole and the third locking through hole are correspondingly provided and a positioning fastener is inserted inside.

[0014] Preferably, the positioning fastener includes a positioning end and an insertion part, the outer diameter of the insertion part increases from both ends to the middle, and multiple movable pieces are provided on the inner cylinder wall, the ends of the multiple movable pieces together forming the second locking through hole.

[0015] The beneficial effects of this utility model are: The first bending piece of the inner cylinder of this utility model has a pre-folded crease, and the outer cylinder is composed of elastically bendable cylindrical pieces. By adjusting the relative position and bending state of the inner and outer cylinders, the unfolding range and overall shape of the lantern can be flexibly changed to meet the diverse decorative scene requirements and enhance the decorative expression. The inner and outer cylinders are quickly positioned by using the plug-in pieces of the end connecting plate in conjunction with the first and second plug holes. The disassembly and assembly process is simple and efficient. When storing, the components can be disassembled or the folding pieces can be folded, which greatly reduces the space occupied and lowers packaging, transportation and storage costs.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0019] Example: like Figure 1-8 As shown, a deformable lantern includes: an inner cylinder 2, an outer cylinder 3, an end connecting plate 4, and an end cap 1. The inner cylinder 2 is made of a light-transmitting material, such as a plastic sheet. The outer cylinder 3 can be made of cardboard or plastic sheet and has a certain degree of elastic deformation.

[0020] The outer cylinder 3 is fitted onto the outside of the inner cylinder 2, and the two end caps 1 are fitted onto the upper and lower ends of the outer cylinder 3 respectively.

[0021] The cross-sectional shape of the inner cylinder 2 and the outer cylinder 3 is circular or regular polygonal. In this embodiment, the cross-sectional shape of the inner cylinder 2 and the outer cylinder 3 is regular hexagonal.

[0022] In other embodiments, the cross-sectional shapes of the inner cylinder 2 and the outer cylinder 3 are circular, square, or regular pentagonal.

[0023] like Figure 4 As shown, a plurality of first bending pieces 201 are distributed at the upper and / or lower ends of the inner cylinder 2. The number of first bending pieces 201 at each end is determined according to the cross-sectional shape of the inner cylinder 2. In this embodiment, the first bending pieces 201 are distributed at both the upper and lower ends of the inner cylinder 2, and the number of first bending pieces 201 at each end is six, distributed on the six sides of the regular hexagon.

[0024] The first bending piece 201 has at least one pre-fold 202, allowing it to be bent inwards by 90° along the pre-fold 202. A first insertion hole 203 is provided at the pre-fold 202. In this embodiment, the first bending piece 201 has two pre-folds 202, which are distributed vertically at intervals. One of the pre-folds 202 is located at the connection between the first bending piece 201 and the inner cylinder 2.

[0025] like Figure 3 As shown, the outer cylinder 3 includes an upper sleeve 301 and a lower sleeve 302 distributed vertically, and a cylindrical plate 303 connecting the upper sleeve 301 and the lower sleeve 302. The cylinder body of the outer cylinder 3 is composed of multiple cylindrical plates 303 that can undergo elastic bending deformation distributed circumferentially. In this embodiment, there are six cylindrical plates 303. When the distance between the upper sleeve 301 and the lower sleeve 302 of the outer cylinder 3 is shortened, the cylindrical plates 303 can bend and arch outward.

[0026] The outer cylinder 3 has a second bending piece 304 at both the upper and lower ends. The second bending piece 304 is distributed on the outer side of the first bending piece 201. The connection between the second bending piece 304 and the end of the outer cylinder 3 is a bend, so that the second bending piece 304 can be bent inward relative to the outer cylinder 3 until it overlaps with the first bending piece 201. A second insertion hole 305 is provided at the bend. When the second bending piece 304 overlaps with the first bending piece 201, the second insertion hole 305 communicates with the first insertion hole 203.

[0027] In this embodiment, the number of second bending pieces 304 in each segment of the outer cylinder 3 is at least two. In this embodiment, the two second bending pieces 304 are symmetrically distributed. In other embodiments, the number of second bending pieces 304 can be the same as the number of first bending pieces 201.

[0028] like Figure 6As shown, the end connecting plate 4 is hexagonal in shape, matching the cross-sectional shape of the outer cylinder 3. Six insert pieces 401 are distributed on the end connecting plate 4. These six insert pieces 401 can be flipped upwards or downwards at a certain angle relative to the end connecting plate 4, allowing the insert pieces 401 to be simultaneously inserted into the corresponding second insertion hole 305 and first insertion hole 203 to position the inner cylinder 2 and the outer cylinder 3, preventing relative movement between them.

[0029] Specifically, the width of the connector 401 increases from the end towards the bend where the connector 401 meets the end connecting plate 4, and a notch 402 is provided near the bend in the connector 401. This facilitates the insertion of the connector 401 into the first socket 203 and the second socket 305, and also allows the edge of the first socket 203 to be engaged in the notch 402, preventing the connector 401 from detaching.

[0030] In its natural state, the length of the outer cylinder 3 after the second bending piece 304 is equal to the length of the inner cylinder 2 after the first bending piece 201 is bent along the outermost pre-crease 202. Figure 1 As shown, the lantern has a hexagonal prism shape after assembly.

[0031] When the first bending piece 201 of the inner cylinder 2 is bent along the innermost pre-fold 202, the length of the inner cylinder 2 is less than the length of the outer cylinder 3. At this time, the two ends of the outer cylinder 3 are aligned with the two ends of the inner cylinder 2 and fixed by the end connecting plate 4. At this time, the six cylindrical pieces 303 of the outer cylinder 3 bend and arch outward, as shown in the structure. Figure 8 As shown.

[0032] The pre-fold lines 202 at different parts of the first bending piece 201 at the upper and lower ends of the inner cylinder 2 are bent to change the different heights of the inner cylinder 2, thereby adjusting the height of the outer cylinder 3 after assembly, so that the six cylindrical pieces 303 of the outer cylinder 3 exhibit different degrees of bending.

[0033] During assembly, lighting components, such as LED lights, can be used to prevent illumination.

[0034] like Figure 1-4 As shown, the end cap 1 is provided with a first locking through hole 101, and the upper and lower ends of the inner cylinder 2 and the outer cylinder 3 are respectively provided with a second locking through hole 204 and a third locking through hole 306. The first locking through hole 101 is provided in correspondence with the second locking through hole 204 and the third locking through hole 306, and a positioning fastener 5 is inserted inside.

[0035] like Figure 7 As shown, the positioning fastener 5 includes a positioning end 501 and an insertion part 502, the outer diameter of which increases from both ends towards the middle. Figure 5As shown, the inner cylinder 2 has multiple elastic movable pieces 205 on its wall. The ends of the multiple movable pieces 205 together form a second locking through hole 204. The movable pieces 205 are made of the same material as the inner cylinder 2. The diameter of the second locking through hole 204 is smaller than the maximum outer diameter of the insertion part 502. Thus, when the insertion part 502 is inserted into the second locking through hole 204, the ends of the movable pieces 205 are squeezed and swing by the insertion part 502, which increases the diameter of the second locking through hole 204. When the insertion part 502 has completely passed through, the movable pieces 205 return to their original position, which reduces the diameter of the second locking through hole 204.
