[0045] Please refer to Figure 1 Up to Figure 3 Now, an adjustable lens module provided by the present utility model will be described. The adjustable lens module includes a rotating rod 10, a moving frame 20, and a lens plate 30. The moving frame 20 cooperates with the rotating rod 10 and is used to reciprocate along a first straight path under the drive of the rotating rod 10. The first straight path is perpendicular to the axial direction of the rotating rod 10. A step 21 is provided on the first side of the moving frame 20; the lens plate 30 is located on the first side of the moving frame 20, and a convex platform 31 is provided on the side of the lens plate 30 facing the moving frame 20.

[0046] Wherein, the lens plate 30 is slidably installed in the lamp body along the first straight path. During the process of the rotating rod 10 driving the moving frame 20 to move, the position of the convex platform 31 on the step 21 is switched to realize the adjustment of the distance between the lens plate 30 and the moving frame 20.

[0047] Compared with the prior art, for the adjustable lens module provided in this embodiment, after the lens module of this embodiment is installed in the lamp, the rotating rod 10 is rotationally fitted in the lamp, and the lens plate 30 is slidably fitted in the lamp. When it is necessary to adjust the beam angle during use, the rotating rod 10 can be rotated. While the rotating rod 10 drives the moving frame 20 to move horizontally, the contact position between the step 21 on the moving frame 20 and the convex platform 31 changes, thereby realizing the elevation or depression of the lens plate 30 along the step 21. During the movement of the lens plate 30, the distance between the lens plate 30 and the light source plate 60 will change, so as to realize the adjustment of the beam angle. The adjustable lens module of the present utility model is convenient to use. During the use process, the user can rotate the rotating rod 10 at any time to realize the adjustment of the lens plate 30, which meets various use scenarios and enhances the user experience.

[0048] In some embodiments, a specific cooperation mode between the above-mentioned moving frame 20 and the rotating rod 10 can adopt the structure as Figures 1 to 2 shown. Refer to Figures 1 to 2 , the moving frame 20 has first teeth 11, and the outer periphery of the rotating rod 10 is provided with second teeth 22 meshing with the first teeth 11. The first teeth 11 on the moving frame 20 are arranged along the first straight path. When the rotating rod 10 rotates, the second teeth 22 mesh with the first teeth 11 to drive the moving frame 20 to move. By rotating the rotating rod 10 forward and backward, the reciprocating movement of the moving frame 20 is realized.

[0049] It should be noted that the first teeth 11 on the moving frame 20 can be provided in only one section, and the second teeth 22 on the rotating rod 10 can also be provided in only half a circle. The number of the first teeth 11 and the second teeth 22 only needs to meet the adjustment stroke of the moving frame 20.

[0050] In some embodiments, a deformation cooperation mode of the above-mentioned moving frame 20 and the rotating rod 10 can adopt the structure as Figure 3 shown. Refer to Figure 3 , a first limiting groove 23 is provided on the second side of the moving frame 20. The second side is the opposite side of the first side. The rotating rod 10 is a screw rod 12. A sleeve 13 is sleeved on the outer periphery of the screw rod 12. The sleeve 13 is in threaded cooperation with the screw rod 12 and is in rotational cooperation with the first limiting groove 23. When the screw rod 12 rotates, due to the threaded cooperation between the sleeve 13 and the screw rod 12, the sleeve 13 will move along the axial direction of the screw rod 12. Furthermore, the end face of the sleeve 13 will abut against the side wall of the first limiting groove 23, driving the moving frame 20 to move along the first straight path. By rotating the screw rod 12 forward and backward, the reciprocating movement of the moving frame 20 is realized.

[0051] In some embodiments, an improved implementation mode of the above-mentioned rotating rod 10 can adopt the structure as Figure 1 shown. Refer to Figure 1 , a knob 40 is provided at the end of the rotating rod 10. During specific implementation, the rotating rod 10 is installed on the lamp, and one end of the rotating rod 10 can extend out of the lamp and the knob 40 can be installed, which is convenient for rotating and adjusting the rotating rod 10.

[0052] Specifically, the knob 40 can be in snap-fit with the rotating rod 10 or integrally formed with the rotating rod 10; for convenient operation, grooves (which can be in the shape of a single line, a cross, a star, etc.) can also be provided on the outer surface of the knob 40 to facilitate screwing the knob 40 with tools such as a wrench.

[0053] In some embodiments, an improved cooperation mode of the above-mentioned step 21 and the boss 31 can adopt the structure as Figure 2 shown. Refer to Figure 2 , the step 21 has stepped surfaces that increase or decrease in sequence along the first straight path, and a guiding inclined surface 211 is connected between adjacent stepped surfaces. An adapting surface 311 parallel to the guiding inclined surface 211 is provided on the boss 31. By providing the guiding inclined surface 211 and the adapting surface 311, it is convenient for the boss 31 to slide up or down on the step 21, and the operation is time-saving and labor-saving.

[0054] Based on the same inventive concept, refer to Figures 4 to 6, the embodiment of the present application further provides a floodlight, which has the above adjustable lens module, and further includes a main body 50, a light source board 60 and a light-transmitting board 70. The main body 50 has a rotating groove 51 for cooperating with the rotating rod 10 and a sliding groove 52 for cooperating with the moving frame 20; the light source board 60 is arranged inside the main body 50, the light source board 60 is located between the moving frame 20 and the lens board 30 and is spaced from the moving frame 20; the light-transmitting board 70 is fixedly connected to the light-emitting side of the main body 50, and the light-transmitting board 70 is located on the side of the lens board 30 away from the light source board 60; wherein, one end of the rotating rod 10 extends out of the outside world.

[0055] It is easy to understand that the light source board 60 is arranged between the lens board 30 and the moving frame 20. The matching structure between the moving frame 20 and the lens board 30 can penetrate the light source board 60, or the width of the light source board 60 is narrower than that of the moving frame 20. Furthermore, the matching structure between the moving frame 20 and the lens board 30 is located at the outer edge of the light source board 60. The above two situations can ensure that the light source board 60 will not be driven to move during the movement of the moving frame 20 and the lifting of the lens board 30.

[0056] Optionally, the light-transmitting board 70 can be a glass board.

[0057] Compared with the prior art, the floodlight provided by this embodiment can conveniently adjust the lens board 30 during use by using the above lens module, change the distance between the lens board 30 and the light source board 60, thereby adjusting the beam angle, meeting various use requirements of users, and there is no need to disassemble and replace the lens board 30, and the use cost is lower.

[0058] In specific implementation, the moving frame 20 can be a rectangular frame structure. An installation table 58 is arranged inside the main body 50. A rectangular groove (i.e., the above-mentioned sliding groove 52) adapted to the shape of the moving frame 20 is recessed on the installation table 58. After the moving frame 20 is placed in the rectangular groove, it is recessed on the side of the installation table 58 facing the light source board 60. Furthermore, the light source board 60 can be placed on the installation table 58 and connected to the installation table 58 by bolts or the like, so as to realize the spaced distribution of the light source board 60 and the moving frame 20.

[0059] In some embodiments, an improved matching method between the above main body 50 and the lens board 30 can adopt the structure as Figures 5 to 6 shown. Refer to Figures 5 to 6 , a positioning post 53 is arranged inside the main body 50, and a through hole 32 for the positioning post 53 to penetrate is arranged on the lens board 30. The axial direction of the positioning post 53 is parallel to the lifting direction of the lens board 30. Since the lens board 30 will lift during the movement of the moving frame 20, through the cooperation of the positioning post 53 and the through hole 32, the lifting process of the lens board 30 can be guided to avoid the lens board 30 being skewed and affecting the light-emitting effect of the light source board 60.

[0060] In some embodiments, an improved implementation manner of the above floodlight can adopt the structure asFigure 5 The structure shown. Refer to Figure 5 , a spring 54 is sleeved on the positioning post 53, and two ends of the spring 54 respectively abut against the lens plate 30 and the light-transmitting plate 70. There is a gap between the free end of the positioning post 53 and the light-transmitting plate 70, so as to satisfy the telescopic process of the spring 54. During the lifting process of the lens plate 30, the spring 54 continuously abuts between the lens plate 30 and the light-transmitting plate 70, stabilizing the moving process of the lens plate 30, and ensuring the gap between the lens plate 30 and the light-transmitting plate 70, avoiding damage caused by excessive adjustment and collision.

[0061] In some embodiments, an improved implementation manner of the above-mentioned main body 50 can adopt the structure as shown in Figures 5 to 6 . Refer to Figures 5 to 6 , a second limiting groove 55 is further provided on the inner wall of the rotating groove 51, and a limiting plate 14 matched with the second limiting groove 55 is provided on the outer periphery of the rotating rod 10. The diameter of the second limiting groove 55 is larger than the diameter of the rotating groove 51. The rotating rod 10 rotates in the rotating groove 51, and the limiting plate 14 rotates in the second limiting groove 55 along with the rotating rod 10. By providing the second limiting groove 55, the rotating rod 10 can be limited axially, avoiding axial misalignment of the rotating rod 10 and affecting the cooperation with the lens plate 30.

[0062] In some embodiments, an improved implementation manner of the above-mentioned main body 50 can adopt the structure as shown in Figure 1 and Figure 3 . Refer to Figure 1 and Figure 3 , an angle mark 56 is provided on the outer surface of the main body 50 corresponding to the position of the rotating rod 10. When one end of the rotating rod 10 extends out of the main body 50, a pointer can be provided at this end of the rotating rod 10; when a knob 40 is provided at one end of the rotating rod 10, a pointer can be provided on the knob 40.

[0063] When rotating the rotating rod 10, it is convenient to judge the rotation angle of the rotating rod 10 through the position of the pointer on the angle mark 56, and the adjustment of the lens plate 30 is more accurate.

[0064] In some embodiments, an improved implementation manner of the above-mentioned main body 50 can adopt the structure as shown in Figure 1 and Figure 3 . Refer to Figure 1 and Figure 3 , a heat dissipation plate 57 is provided on the backlight side of the main body 50. By providing the heat dissipation plate 57, it is beneficial to dissipate heat from the light source plate 60 inside the main body 50 during use, avoiding overheating and damage of the light source plate 60, and prolonging the service life of the floodlight.

[0065] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
