Description

Technical Field

[0001] The utility model relates to the technical field of lighting appliances, in particular to a liftable lighting appliance. Background Art

[0002] Lighting appliances are also called light bulbs or electric lamps. This category refers to devices that convert electrical energy into light. Currently, they can be divided into incandescent lamps, gas discharge lamps and light-emitting diode lamps according to the principle of light emission. Existing lighting appliances are generally used in the configuration of lamp poles and lamp heads for community basketball courts, activity squares or other activity venues.

[0003] For example, publication number CN213237301U discloses an electric liftable lighting appliance, in which a worker starts the motor and runs it, thereby driving the spiral shaft to rotate and driving the spiral sleeve to achieve the lifting effect, thereby realizing the lifting and lowering adjustment of the lighting lamp panel.

[0004] However, the adjustment machine structure cannot adapt well to small lighting appliances when in use, because small lighting appliances can usually be carried and moved manually and then placed on the ground for use, while the use of devices such as motors is not only costly but also heavy, thus affecting the convenience of small lighting appliances. In addition, when small lighting appliances are placed directly on a relatively soft ground, they are prone to tipping over and affecting their use. In view of this, we propose a liftable lighting appliance. Utility Model Content

[0005] The purpose of the utility model is to provide a liftable lighting appliance to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a liftable lighting appliance, comprising a lighting lamp body, a fixing frame is arranged at the lower end of the lighting lamp body, an adjustment structure is arranged inside the fixing frame, and the adjustment structure comprises:

[0007] A cavity, wherein the cavity is opened inside the fixing frame, the inner wall of the cavity is rotatably connected to a screw through a shaft sleeve, the surface of the screw is threadedly connected to a sleeve, the upper end of the sleeve passes through the upper end of the fixing frame and is fixedly mounted with a support plate, and the support plate is fixedly connected to the lower end of the lighting lamp body;

[0008] A first tooth plate, the first tooth plate is fixedly mounted on both sides of the sleeve, second tooth plates are slidably connected to both sides of the inner wall of the cavity, one end of a rotating rod is rotatably connected to both sides of the inner wall of the cavity, a rotating gear is fixedly mounted on the other end surface of the rotating rod, a connecting plate is fixedly mounted on the lower end of the second tooth plate, an insertion rod is fixedly mounted on the lower end of the connecting plate, and a stabilizing structure is arranged inside the insertion rod.
