DETAILED DESCRIPTION

[0024] The directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the invention of the utility model.

[0025] Example 1

[0026] like Figure 1-4 As shown, a retractable children's projection lamp comprises a shell 1, a projection head 2 is fixedly connected to the head of the shell 1, a sleeve 4 is slidably connected inside the shell 1, a lamp holder 5 is rotatably connected to the sleeve 4 on one side of the projection cover 22, a projection lamp 51 is installed on the lamp holder 5, a driving motor 7 and a battery are installed on the inner side of the sleeve 4, the driving motor 7 drives the projection lamp 51 to rotate, and performs rotary projection to improve interest and flexibility; while the projection lamp 51 rotates, it can be retracted and extended through the sleeve 4, so as to conveniently change the shape, adjust the projection direction, project toward the roof or wall, and adjust the size of the projection area.

[0027] Specifically, the projection head 2 is in the shape of a bullet head, and the two sides of the shell 1 extend outward to form a wing part 11, and a cabin part 12 is arranged between the two wing parts 11, and the shape is rounded, and the appearance is highly child-friendly; a cavity 111 is arranged in the wing part 11, and a slide groove is arranged on the inner wall of the cavity 111, and a T-shaped slider 41 is fixedly connected to the side wall of the sleeve 4, and the T-shaped slider 41 is slidably connected to the slide groove, and has high sliding stability; the T-shaped slider 41 includes a sliding part and a limiting part, the limiting part is fixed at the end of the sliding part, and guide grooves are formed on both sides of the sliding part; further, the shell 1 is split into two parts, and the two parts are joined together to form a complete wing part 11 and a slide groove, and the side wall of the shell 1 is clamped in the guide groove of the T-shaped slider 41, thereby realizing the coordinated installation of the T-shaped slider 41 and the slide groove.

[0028] Furthermore, a limiting groove 411 is provided on the outer side (i.e., the side close to the shell 1) of the T-shaped slider 41, and a fixing column 61 is fixedly connected in the cavity 111. The fixing column 61 is connected to the limiting block 6 through a pressure rod. The end of the limiting block 6 is a friction portion. The friction portion is long and strip-shaped, and its length direction is in line contact with the limiting groove 411. The cross-section is semicircular. Under the action of pressure, the line contact is changed to surface contact; the pressure rod is an elastic plastic part, which can provide pressure for the limiting block 6, so that the limiting block 6 is close to the side wall of the limiting groove 411, forming a limit on the sleeve 4 to limit the distance between the projection lamp 51 and the projection head 2.
