Description

Technical Field

[0001] The utility model relates to a solar wall lamp. Background Art

[0002] As a variation of garden lights, wall lamps can provide necessary lighting, embellish the scenery, brighten the landscape and beautify the environment. Therefore, they are widely used in many places now, such as urban roads, community roads, industrial parks, courtyards, etc., as well as buildings that need to be illuminated and decorated.

[0003] For example, a solar wall lamp disclosed in Chinese patent publication number CN211011155U discloses that the wall lamp body includes a shell, a base plate, an LED light board, a storage battery, a fixing plate and a solar power panel, the base plate is fixedly connected to the shell by screws to form a receiving cavity, a circuit board is arranged in the receiving cavity, a light-transmitting plate is arranged on one side of the shell, the LED light board is arranged in the receiving cavity and scatters light outward through the light-transmitting plate, a solar power panel is arranged on the other side of the shell, a groove is arranged on the base plate, studs are arranged on both sides of the groove, and the fixing plate fixes the storage battery in the groove by screws.

[0004] In summary, the base plate and the shell of the current wall lamp are fixedly connected by screws to form a accommodating cavity. However, the above method requires preset screw holes in the shell, and screw through holes are opened on the base plate corresponding to the screw holes. During actual processing, the center alignment between the screw hole and the screw through hole is easily offset to one side due to processing errors. The current conventional installation method is to directly connect the screw hole with the screw hole through the screw through the screw through the screw hole. When connected by screws, the base plate is forced to deform or offset relative to the shell to align the screw hole with the center of the screw through the screw. However, when this method is used, the base plate will offset or deform to one side relative to the shell, which will cause a gap or increase the gap on the other side, resulting in poor waterproof effect of the connection between the base plate and the shell.

[0005] Based on this, it is necessary to provide a solar wall lamp to address the above-mentioned problems. Utility Model Content
