Based on the embodiments in 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.
[0032] See also Figure 1-7 The utility model describes the above technical solution in detail through the following embodiments:
[0033] A variable-focus lamp with a focusing structure comprises a lamp holder 1, a shell 2 is arranged on the outer side of the lamp holder 1, a lamp board assembly 3 is arranged on the side of the shell 2 close to the lamp holder 1, a fixed lens 4 is arranged between the lamp board assembly 3 and the shell 2, a movable lens 5 is arranged on one side of the fixed lens 4, and a connecting piece 6 is arranged on the side of the movable lens 5 away from the fixed lens 4. A sliding piece 7 is movably arranged in the guide groove 11 provided on the lamp holder 1, and in the process of pushing the sliding piece 7, a sliding protrusion 72 at the bottom pushes the connecting piece 6 to rotate, and the movable lens 5 rotates together, and the light emitted by the lamp board assembly 3 is adjusted into different lights when the movable lens 5 is rotated to different angles, so that the dimming process is achieved by rotating the movable lens 5, and there is no need to reserve space for horizontal movement of the movable lens 5 like a traditional focusing lamp, thereby reducing the volume of the lamp body.
[0034] It should be noted that the center position of the lamp panel assembly 3 is a lamp bead that can emit light.
[0035] Furthermore, the housing 2 is fixedly connected to the lamp holder 1, a groove 21 is provided on the inner wall of the housing 2, and the lamp holder 1 is fixedly connected to the housing 2 to form a lamp shell for loading other parts.
[0036] It should be noted that the lamp holder 1 has built-in batteries and wires, and the lamp panel assembly 3 is installed on the lamp holder 1 and powered on to provide lighting.
[0037] Furthermore, a protrusion 41 is fixedly provided on the side of the fixed lens 4 , and the protrusions 41 are evenly spaced along the periphery of the fixed lens 4 . The housing 2 and the fixed lens 4 can be fixedly connected together by the snap-fitting between the groove 21 and the protrusion 41 .
[0038] Furthermore, a rotating shaft 42 is provided at the center of the fixed lens 4, and an opening 51 corresponding to the rotating shaft 42 is provided at the center of the movable lens 5. The cooperation between the rotating shaft 42 and the opening 51 can ensure that the movable lens 5 always rotates around the center.
[0039] Furthermore, the side of the movable lens 5 is symmetrically provided with positioning notches 52 , and the connecting member 6 is provided with convex portions 61 corresponding to the positioning notches 52 . The movable lens 5 can be fixedly connected to the connecting member 6 through the snap fit between the positioning notches 52 and the convex portions 61 .
[0040] It is worth noting that at least two symmetrical positioning notches 52 are provided on the side surface of the movable lens 5 .
[0041] In particular, the surface of the movable lens 5 facing the connecting member 6 is provided with a plurality of light-transmitting grooves 53 with different inclinations. By rotating the movable lens 5 so that different light-transmitting grooves 53 on it face the light, the irradiation angle of the light can be changed (e.g. Figure 6 and Figure 7 shown).
[0042] Furthermore, a guide groove 11 is provided at the top of the lamp holder 1, and a sliding member 7 is movably provided in the guide groove 11.

[0044] Furthermore, an oblique groove 62 is provided at one end of the connecting member 6 away from the movable lens 5. By providing the oblique groove 62, a sliding protrusion 72 at the bottom of the sliding member 7 can move in the oblique groove 62, and the sliding protrusion 72 will contact and squeeze the oblique groove 62 during the movement, thereby prompting the connecting member 6 to rotate.
[0045] It should be added that an annular support rail is provided inside the lamp holder 1, and an annular guide rail groove that cooperates with the annular support rail is provided on the back of the connecting member 6. The annular support rail can move in the annular guide rail groove. This arrangement can ensure the rotation of the connecting member 6 inside the lamp holder 1.
[0046] Working principle:
[0047] When the variable focus lamp with a focus adjustment structure of the utility model is used, first, the user pushes the sliding member 7 to move, and the sliding protrusion 72 on the sliding member 7 moves along the inclined groove 62. The sliding protrusion 72 contacts and squeezes the inclined groove 62 during the movement, thereby causing the connecting member 6 to rotate, and the movable lens 5 rotates together. The light emitted by the light board assembly 3 is adjusted to different lights when the movable lens 5 rotates to different angles. In this way, the light emitted by the light board assembly 3 is adjusted when the sliding member 7 is pushed.
[0048] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
