[0022] The following is combined with Figure 1-Figure 3 The present application is further described with reference to the following specific examples:

[0023] First of all, it should be noted that in the description of this application, if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and other directional words appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of this application; in addition, if the terms "first", "second", "third" and other numerical quantifiers appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", and "connected" appear, they should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, an interference fit, a transition fit and other limited connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium; therefore, for ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0024] like Figures 1 to 3 As shown, an LED decorative lamp includes: a shell 2, several lamp panels 3 and a transparent shell 4. A mounting portion 21 is provided at the bottom of the shell 2, and each mounting portion 21 is provided with a positive and negative electrode sheet 211 connected to a power supply. Several lamp panels 3 are detachably mounted on the mounting portion 21, and correspond one to one. The positive and negative poles 31 of the lamp panels 3 are correspondingly connected to the positive and negative electrode sheets 211 on the mounting portion 21; one side of the transparent shell 4 is hinged to the shell 2, and the other side of the transparent shell 4 is connected to the shell 2 by a buckle 41.

[0025] In this application, when the LED decorative lamp is connected to a suitable power supply, the current is transmitted through the positive and negative electrodes 211 on the mounting part 21 to the positive and negative poles 31 of the lamp board 3 connected thereto, thereby providing electrical energy for the LED lamp beads on the lamp board 3, causing the lamp beads to emit light. The light emitted by the lamp beads is scattered outward through the transparent shell 4, achieving the effect of decorative lighting. Since the lamp board 3 and the mounting part 21 are detachably connected, customers can arrange the layout of the lamp beads according to their own needs, such as arranging the lamp beads into the shape of a puppy, a kitten, or a plant.

[0026] Furthermore, a limiting groove is provided on the housing 2 at a position corresponding to the buckle 41 .

[0027] Specifically, the mounting portion 21 includes four catches 212, and the catch 212 includes a limiting portion 2121 vertically arranged on the bottom wall 21221 of the shell 2, and a limiting step 2122 is provided on the limiting portion 2121. The bottom surface of the limiting step 2122 is parallel to the bottom wall 21221 of the shell 2, and the bottom surface of the limiting step 2122 serves as a bearing surface for the lamp board 3. An elastic limiting piece 2123 is provided at the top of the limiting portion 2121, and a limiting gap 2124 is formed between the elastic limiting piece 2123 and the bearing surface, and the limiting gap 2124 is for the lamp board 3 to be snapped in.

[0028] When the lamp board 3 needs to be installed, it is only necessary to insert one side of the lamp board 3 into the limit interval 2124 on the corresponding side, and then press the other side of the lamp board 3 into the limit interval 2124 on the other side. When the lamp board 3 is fully inserted, the elastic limit plate 2123 restores part of its elastic deformation, which limits the lamp board 3 and prevents it from easily falling out. At this time, the positive and negative poles 31 of the lamp board 3 are in close contact with the positive and negative plates 211 on the mounting part 21, and the current can be smoothly transmitted through the positive and negative plates 211 to the lamp board 3, driving the LED lamp beads on the lamp board 3 to emit light.

[0029] The limiting gap 2124 formed by the elastic limiting piece 2123 and the bearing surface can accurately clamp the lamp board 3, ensuring that the position of the lamp board 3 is stable after installation, and it is not easy to be displaced or fall off even when subjected to a certain degree of vibration, shaking or external force impact.

[0030] Specifically, the elastic limiting piece 2123 is a metal spring piece having a guide portion 21231 . The guide portion 21231 gradually approaches the bottom wall 21221 of the housing 2 from one end close to the limiting portion 2121 .

[0031] The guide portion 21231 of the metal spring gradually approaches the bottom wall 21221 of the housing 2 from one end close to the limiting portion 2121 . This special shape provides a clear guide path for the insertion of the lamp board 3 .

[0032] When installing the light board 3, the entire elastic limit piece 2123 will be squeezed away from the light board 3 during the process of pressing down along the guide part 21231, and the operator can more easily slide the light board 3 into the limit gap 2124 accurately along the inclined direction of the guide part 21231.

[0033] The combination of the rigidity and elastic properties of the metal shrapnel can not only stably fix the lamp board 3, but also compensate to a certain extent for the thickness changes that may be caused by factors such as the manufacturing tolerance of the lamp board 3, so that each lamp board 3 can be installed better. In addition, the wear resistance of the metal shrapnel will be better and the service life will be longer.

[0034] Specifically, the top of the metal dome has a toggle portion 21232 .

[0035] This design allows the user to manually apply force to the toggle portion 21232 when the light board 3 needs to be disassembled, thereby moving the elastic limiting piece 2123 away from the light board 3.

[0036] Specifically, the metal spring is an integrally formed structure.

[0037] It should be noted that the above embodiments are only used to illustrate the present application and are not intended to limit the technical solutions described in the present application. Although this specification has described the present application in detail with reference to the above embodiments, ordinary technicians in this field should understand that technicians in the relevant technical field can still modify or replace the present application with equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present application should be included in the scope of the claims of the present application.
