[0068] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0069] Example 1

[0070] See also Figure 1 The first embodiment of the foldable annular decorative lamp stand of the utility model, the decorative lamp stand of this embodiment includes: a lighting unit 1 and a locking unit 2. Among them, the lighting unit 1 is ring-shaped in the plane, and there is a virtual marginal dividing line X between adjacent lighting units 1, and the marginal dividing line X extends radially in a radial shape. The locking unit 2 quickly locks the adjacent lighting units 1 on the left and right sides of the marginal dividing line X with each other, so that the lighting units 1 form a ring-shaped structure with a stable structure in the plane. The number of lighting units 1 in this embodiment is six, and the number of locking units 2 is six. The six lighting units 1 form a ring-shaped snowflake structure in the plane, and the adjacent lighting units 1 are locked and connected by the locking unit 2, thereby forming a decorative lamp stand with a stable snowflake structure.

[0071] When in use, the adjacent lighting units 1 are quickly locked together by the locking units 2, and under the restriction of the locking units, a stable snowflake-shaped decorative lamp stand is formed. When the locking units 2 that are locked and connected between the lighting units 1 are unlocked and separated, the lighting units 1 can be stacked together in a stacked manner, reducing the space they occupy and saving storage and transportation space.

[0072] like Figure 2 and Figure 3 , the decorative lamp frame also includes hinge units 3. In this embodiment, the number of lighting units 1 is six. The lighting units 1 are ring-shaped in the plane. There is a virtual marginal dividing line X between adjacent lighting units 1. The number of hinge units 3 for hinge connection between lighting units 1 is five. The axis of the hinge unit 3 extends along the marginal dividing line X and is arranged corresponding to the locking unit 2 to connect the adjacent lighting units 1, so that the adjacent lighting units 1 can be connected and folded with each other along the hinge units 3. It should be noted that the hinge unit 3 is used to realize the shaft connection between the adjacent lighting units 1 on one side; the locking unit 2 between the other sides of the adjacent lighting units 1 and corresponding to the hinge unit 3 locks the adjacent lighting units 1.

[0073] When folding the decorative lamp stand, first unlock the lock unit 2 between two adjacent lighting units 1, that is, release the locking state between the adjacent lighting units 1, and then fold the adjacent lighting units 1 one after another along the marginal dividing line X. The folded decorative lamp stand is as follows: Figure 3 As shown, the space occupied by the decorative lamp holder is reduced, and during transportation, the decorative lamp holder does not need to be packaged in a specific shape such as snowflakes, thereby saving storage and transportation space and reducing production costs.

[0074] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the lighting unit 1 of this embodiment is approximately fish-shaped in its plane, and the lighting unit 1 includes: two locking frames 11 and a plurality of connected lighting frames 12, the lighting frame 12 and the two locking frames 11 are extended and connected in their planes, and a flexible light strip is installed in the lighting frame 12. Preferably, the lighting frame 12 and the locking frame 11 are integrally formed.

[0075] The two locking frames 11 are distributed on the inner side of the two left and right marginal dividing lines X of the lighting unit 1, and are used to install the locking unit 2 and the hinge unit 3. Specifically, the inner side of a marginal dividing line X of the lighting unit 1 has two locking frames 11, one of the two locking frames 11 is installed with the locking unit 2, and the other locking frame 11 is oppositely installed with the hinge unit 3, and the installation positions of the locking unit 2 and the hinge unit 3 on the two locking frames 11 are interchangeable.

[0076] It should be noted that if Figure 5 As shown, the left and right sides of each lighting unit 1 are both provided with upper and lower locking frames 11. For one side of the lighting unit 1, the upper locking frame 11 is provided with the locking unit 2, and the lower locking frame 11 is provided with the hinge unit 3. Meanwhile, for the other side of the lighting unit 1, the upper locking frame 11 is provided with the hinge unit 3, and the lower locking frame 11 is provided with the locking unit 2. In other words, the locking units 2 and hinge units 3 installed on the two locking frames 11 on the inner side of the two marginal dividing lines X on the left and right sides of the lighting unit 1 are staggered.

[0077] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, two locking walls 111 are provided on the locking frame 11 of the lighting unit 1, and the locking walls 111 are perpendicular to the plane of the lighting unit 1. The two locking walls 111 are parallel to each other and extend longitudinally along the locking frame 11; two transverse support plates 112 are provided between the two parallel locking walls 111, and the two ends of the transverse support plates 112 are respectively connected to the inner walls of the two locking walls 111, and the transverse support plates 112 are perpendicular to the locking walls 111 and perpendicular to the longitudinal direction of the locking frame 11.

[0078] The structure of the lock frame 11 is as follows Figure 7As shown, in the two mutually parallel locking walls 111 of the locking frame 11, the two edges of the front or rear sides of the locking wall 111 of the locking frame 11 close to the marginal dividing line X are respectively provided with longitudinally extending rectangular notches 113 for sinking the thickness of the locking unit 2 or the hinge unit 3, and the locking wall 111 of the locking frame 11 far from the marginal dividing line X is provided with a rectangular locking groove 111a. The two horizontal support plates 112 are correspondingly provided with rectangular locking holes 112a, and the two horizontal support plates 112 are also correspondingly provided with pivot holes 112b.

[0079] like Figure 4 , Figure 5 and Figure 8 As shown, the lighting frame 12 has two lighting walls 121 arranged parallel to each other, the two lighting walls 121 are perpendicular to the plane of the lighting unit 1, and extend in the longitudinal direction of the lighting frame 12. Among them, a plurality of rear edge support plates 122 are arranged between the rear edges of the two lighting walls 121, and the rear edge support plates 122 are respectively connected to the same side of the two lighting walls 121, and the rear edge support plates 122 are arranged perpendicular to the lighting walls 121 and parallel to the longitudinal direction of the lighting frame 12. Here, the two lighting walls 121 and the rear edge support plates 122 form a groove-shaped channel 123 of the lighting frame 12. The groove-shaped channel 123 is distributed in a fish-shaped skeleton in the plane of the lighting unit 1, and a flexible light strip is laid in the longitudinal direction of the lighting frame 12.

[0080] As a further improvement, Figure 6 and Figure 8 On the inner side of the front edge of the two decorative walls 121 of the lighting frame 12, longitudinal flanges 124 are arranged discontinuously opposite to each other. The longitudinal flanges 124 are used to prevent the flexible light strip from slipping out of the groove-shaped channel 123. At the same time, as a further improvement, on one edge of the rear edge support plate 122, and along the inner side of the two decorative walls 121, opposite positioning flanges 125 are arranged to extend forward. The paired positioning flanges 125 are used to limit the flexible light strip to the center of the two decorative walls 121.

[0081] It must be noted that if Figure 4 , Figure 6 and Fig. 9As shown, the lighting frame 12 serves as a carrier of the lighting unit 1 for carrying the flexible light strip, and the lighting frame 12 includes: a main lighting frame 12a and a sub-lighting frame 12b. Among them, the main lighting frame 12a coincides with the symmetrical bisector YY of the two locking frames 11 of the lighting unit 1, and the main lighting frame 12a is radial; the sub-lighting frames 12b are arranged in pairs on both sides of the main lighting frame 12a, and are connected to the main lighting frame 12a. The tail ends of the two pairs of sub-lighting frames 12b close to the inner ends of the main lighting frame 12a are respectively connected to the inner and outer ends of the two locking frames 11. The lighting frame 12 is beautifully designed, and multiple lighting frames 12 can be combined into special patterns, such as snowflake decorative lights, to increase the aesthetics.

[0082] like Fig.10 , Fig.11 and Fig.12 As shown, in this embodiment, to simplify the diagram, Figures 10 to 12 Only the assembly mechanism of two lighting units 1 is shown for illustration. The hinge unit 3 is installed on the two locking frames 11 of the two adjacent lighting units 1. The opening and closing directions of the two hinge units 3 on the two locking frames 11 of the lighting units 1 are opposite to each other, so that the two adjacent lighting units 1 on the left and right can be folded one after the other along their marginal dividing line X. Fig.10 As shown, the grooved channels of two adjacent lighting units 1 face the same side. When the hinge unit 3 is installed on the opposite locking frames 11 of the two adjacent lighting units 1, the two lighting units 1 are folded along the marginal dividing line X and the grooved channels of the lighting units 1 are attached together (as shown in FIG. Fig.12 ).like Figure 1 and Figure 2 As shown, in the annular decorative lamp stand of this embodiment, the hinge unit 3 is installed at the position of two locking frames 11 of adjacent lighting units 1, so that the adjacent lighting units 1 can be folded forward or backward continuously along the marginal dividing line X.

[0083] like Fig.10 , Fig.11 and Fig.13 As shown, the hinge unit 3 includes two symmetrical hinges 31, and the two hinges 31 are respectively installed in the lock frame 11 of the adjacent lighting units 1. The two hinges 31 are connected by the pin of the hinge unit 3, so that the adjacent lighting units 1 can be connected by the pin of the hinge unit 3. In order to install the hinge unit 3 on the lock frame 11 of the adjacent lighting unit 1, elastic locking tongues 33 are provided at two symmetrical ends of the pin axis direction of the hinge 31. The elastic locking tongues 33 are connected to the rectangular locking holes 112a (such as the two parallel horizontal support plates 112 of the lock frame 11) on the two parallel horizontal support plates 112 of the lock frame 11. Figure 7) are adapted. When the hinge unit 3 is installed, its elastic locking tongue 33 is connected to the rectangular locking hole 112a of the transverse support plate 112, so that the hinge unit 3 can be quickly installed in the locking frame 11 of the adjacent lighting unit 1. Since the hinge unit 3 adopts a screw-free installation method, the installation is quick and convenient.

[0084] like Figure 7 , Fig.11 and Fig.13 , the elastic locking tongue 33 of the hinge unit 3 is further improved. The elastic locking tongue 33 is mainly composed of an elastic transverse section 331 and an oblique locking hook 332. The elastic transverse section 331 extends backward from the two symmetrical ends of the hinge 31 along the inner side of the transverse support plate 112 and is arranged parallel to the transverse support plate 112; the oblique locking hook 332 is arranged at the tail of the elastic transverse section 331, which extends longitudinally to the outer side of the transverse support plate 112 and is matched and connected with the rectangular locking hole 112a on the transverse support plate 112. When the hinge unit 3 is installed, the oblique locking hook 332 of the elastic locking tongue 33 is aligned with the rectangular locking hole 112a on the transverse support plate 112 of the lock frame 11 and connected, so that the oblique locking hook 332 of the elastic locking tongue 33 can be smoothly inserted into the locking hole 112a on the transverse support plate 112, and the elastic locking tongue 33 of the hinge unit 3 is reliably connected to the locking hole 112a of the lock frame 11 of the lighting unit 1. In this embodiment, the elastic locking tongue 33 of the hinge mechanism 2 cooperates with the rectangular locking hole 112a on the horizontal support plate 112 of the lock frame 11, and a screw-free installation method is adopted, which greatly improves the production and assembly efficiency of the decorative lamp holder.

[0085] like Figure 7 , Fig.10 , Fig.13 , Fig.14 and Fig.15 As shown, in this embodiment, to simplify the diagram, Fig.14Only two lighting units 1 and the assembly mechanism of the locking unit 2 are shown for illustration. The locking unit 2 will quickly lock and connect the two adjacent lighting units 1 on the left and right sides of the marginal dividing line, so that a stable state is formed between the two lighting units 1. Among them, the locking unit 2 includes a locking plate 21, and the two symmetrical ends of the longitudinal side of the locking plate 21 are respectively provided with elastic pivots 22, and the axis of the elastic pivot 22 is parallel to the axis of the pin of the hinge 31. The elastic pivot 22 is used to connect to the pivot holes 112b of the two parallel transverse support plates 112 in the locking frame 11. In the middle of the other longitudinal side of the locking plate 21, there is a quickly operable elastic lock 23 with a U-shaped bend, and the elastic lock 23 is used to connect to the longitudinally extending rectangular lock groove 111a on the lock wall 111 of the lock frame 11 of the adjacent lighting unit 1. The elastic pivot 22 on one side of the locking unit 2 is axially connected to one of the two adjacent lighting units 1, and the elastic lock 23 on the other side of the locking unit 2 is fixedly connected to the locking wall 111 of the locking frame 11 of the other lighting unit 1 of the two adjacent lighting units 1. Therefore, the two adjacent lighting units 1 are locked and connected through the locking unit 2.

[0086] It should be noted that the lock plate 21 of the lock unit 2 and the hinge 31 of the hinge unit 3 are respectively installed in front of or behind the lock frame 11 of the adjacent lighting unit 1 and are arranged opposite to each other. The two edges of the lock wall 111 of the lock frame 11 close to the marginal dividing line X are respectively provided with rectangular notches 113 for sinking the thickness of the hinge 31 or the lock plate 21.

[0087] When in use, when the locking unit 2 locks the adjacent lighting unit 1, the adjacent lighting unit 1 is in a stable unfolded state. After the locking plate 21 of the locking unit 2 is unlocked from the locking groove 111a on the locking wall 111 of the locking frame 11 relative to the other lighting unit 1, the adjacent lighting unit 1 can be folded along the hinge 31 of the hinge unit 3.

[0088] like Fig.15 and Fig.16As shown, in the lock catch unit 2 of this embodiment, the lock catch unit 2 includes a lock plate 21, an elastic pivot 22 and an elastic lock catch 23. The elastic pivot 22 includes a short shaft 221 and a wedge-shaped groove 222. The short shaft 221 is located behind the two symmetrical ends of the longitudinal side of the lock plate 21, and is coaxially arranged and matched with the pivot hole 112b on the transverse support plate 112 of the lock catch frame 11; the wedge-shaped groove 222 is perpendicular to the axis direction of the pin of the lock plate 21, and is opened on the lock plate 21 connected along the root of the short shaft 221. The function of the wedge-shaped groove 222 is to facilitate the elastic deformation of the elastic pivot 22. When the elastic pivot 22 is installed, a force is applied along the axial direction of the elastic pivot 22 so that the short axis 221 of the elastic pivot 22 is squeezed inward along its axial direction. When the two short axes 221 of the elastic pivot 22 are respectively aligned with the pivot holes 112b on the transverse support plate 112 in the locking frame 11 of the lighting unit 1, the force on the short axis 221 of the elastic pivot 22 is released, and the two short axes 221 of the elastic pivot 22 can be inserted into the above-mentioned pivot holes 112b, thereby completing the quick installation of the elastic pivot 22 of the locking unit 2.

A set of locking units, including six locking units 2 as a group, is used to lock the six lighting units 1 together. A set of hinge units, including five hinge units 3 as a group, is used to fold the six lighting units 1 into six layers in sequence, one front and one back.

[0093] It should be noted that if Fig.17 The diagram shows the exploded structure of the annular decorative lamp stand, which includes a group of lighting units formed by six lighting units 1 in a ring shape, a group of locking units, six locking units 2 in a group, and is used to lock the six lighting units 1 to each other. A group of hinge units, five hinge units 3 in a group. A locking unit and a hinge unit are arranged between two adjacent lighting units 1. From the plane side of the annular decorative lamp stand, the locking unit and the hinge unit are alternately distributed, and from the plane side of the annular decorative lamp stand, the locking unit and the hinge unit are also alternately distributed. A set of flexible lamps 4 are distributed in the grooved channel of the lighting frame of the snowflake structure, and the flexible lamp belt 4 is electrically connected to the controller, and a plurality of LED lamps are arranged on the flexible lamp belt 4; when the decorative lamp stand is folded, the flexible lamp belt 4 is folded along with the lighting unit 1; when in use, the flexible lamp belt 4 is powered on, and the flexible lamp belt 4 with LED lamps emits light, and the decorative lamp stand is shaped like a snowflake, and has a beautiful shape.

[0094] Example 2

[0095] like Fig.19 As shown, the difference between this embodiment and embodiment 1 is that the lighting unit is longer, but the density of the longitudinal flanges and positioning flanges in the internal groove-shaped channel remains unchanged.

[0096] It should be noted that in the above two embodiments, the decorative lamp frame includes six lighting units, each lighting unit has opposite side walls with the adjacent lighting units on both sides, and the locking frames at the upper and lower ends of each side wall can be installed with locking units or linking units. The six lighting units are connected into a snowflake structure through the locking units. Viewed along the vertical direction of the lighting units, the locking units and linking units between the six lighting units are staggered.

[0097] like Figure 20 to Figure 25 As shown, the folding of the ring-shaped decorative lamp stand is explained:

[0098] like Fig. 20The figure shows a schematic diagram of a ring-shaped decorative lamp stand in use, and the decorative lamp stand includes: a group of lighting units, a group of locking units, a group of hinge units, and a set of flexible light strips. Among them, six lighting units form a group, six locking units form a group, and six hinge units form a group. The six lighting units are folded into six layers in sequence, one front and one back. For the convenience of explanation, the six lighting units of a group of lighting units are numbered in sequence, namely a1 to a6 lighting units, and the six locking units of a group of locking units are numbered in sequence, namely b1 to b6 locking units; the six hinge units of a group of hinge units are numbered in sequence, namely c1 to c6 hinge units.

[0099] The specific folding steps are as follows:

[0100] The first step, such as Fig. 20 , separate the lock unit b1 and the hinge unit c1 between the adjacent lighting units a1 and a6. At this time, the lock unit b1 and the hinge unit are respectively located on the upper and lower lock frames between the lighting units a1 and a6. That is to say, the elastic lock of the lock unit b1 is disengaged from the rectangular lock groove of the lock wall of the lighting unit a1, and the pins of the two symmetrical hinges of the hinge unit c1 are pulled out to separate the lighting units a1 and a6. In the first step, it should be noted that the hinge unit c1 is assembled between the lighting units a1 and a6 to increase the stability of the decorative lamp stand in the unfolded state. Of course, the hinge unit c1 between the lighting units a1 and a6 can also be omitted, which also saves the operation of pulling out the pins of the two symmetrical hinges of the hinge unit c1.

[0101] The second step is, Fig.21 , unlock the locking unit b2, and fold the lighting unit a1 forward along the hinge unit c2, so that the lighting unit a1 and the lighting unit a2 are folded and fit together.

[0102] The third step is Fig. 22 , unlock the lock unit b3, and fold the folded lighting unit a1 and lighting unit a2 backward along the hinge unit c3, so that the lighting unit a1, the lighting unit a2 and the lighting unit a3 are folded together.

[0103] The fourth step is Fig.23 , unlock the locking unit b4, and fold the folded lighting unit a1, lighting unit a2 and lighting unit a2 forward along the hinge unit c4, so that the lighting unit a1, lighting unit a2, lighting unit a3 and lighting unit a4 are folded together.

[0104] Step 5: Fig.24, unlock the locking unit b5, and fold the lighting unit a1, lighting unit a2, lighting unit a3 and lighting unit a4 that have been folded in the fourth step backwards along the hinge unit c5, so that the lighting unit a1, lighting unit a2, lighting unit a3, lighting unit a4 and lighting unit a5 are folded together.

[0105] Step 6: Fig.25 , unlock the locking unit b6, and fold the lighting unit a1, lighting unit a2, lighting unit a3, lighting unit a4 and lighting unit a5 that have been folded in the fifth step forward along the hinge unit c6, so that the lighting unit a1, lighting unit a2, lighting unit a3, lighting unit a4, lighting unit a5 and lighting unit a6 are folded together to complete the folding of the decorative lamp stand.

[0106] It must be noted that when the annular decorative lamp stand is folded, one of the six hinge units in a group of hinge units is first split. Specifically, for the hinge unit connecting any two adjacent lighting units, the pin between the two symmetrical hinges of the hinge unit is removed to separate the two hinges of the hinge unit, and the other five hinge units do not need to be disassembled. Therefore, the folded decorative lamp stand includes: lighting units, six pieces in a group; locking units, six pieces in a group; hinge units, five pieces in a group. When the decorative lamp stand is to be unfolded, the pin between the two symmetrical hinges of the above-mentioned split hinge units is reinstalled, and a group of locking units is used to lock the two adjacent lighting units in turn. When the decorative lamp stand is unfolded, it presents a snowflake structure, which is more stable. At this time, the decorative lamp stand in use includes: lighting units, six pieces in a group; locking units, six pieces in a group; hinge units, six pieces in a group.
