DETAILED DESCRIPTION

[0024] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0025] The present invention is a lens angle adjustment structure, comprising an outer cover 10 having an active cavity 11, a light source assembly 20 installed at one end of the active cavity 11, a lens assembly 30 fitted in the active cavity 11, a rotating member 40 arranged between the light source assembly 20 and the lens assembly 30, a first resetting member 50 arranged between the rotating member 40 and the light source assembly 20, and a second resetting member 60 arranged between the other end of the active cavity 11 and the lens assembly 30.

[0026] The inner wall of the movable cavity 11 is provided with a limiting rib 111 arranged along the axial direction of the outer cover 10 .

[0027] A slider 311 is disposed on the outer periphery of the lens assembly 30 .

[0028] The outer circumference of the rotating member 40 is provided with a plurality of groups of limiting points 41 with different heights. The plurality of groups of limiting points 41 are cyclically arranged on the outer circumference of the rotating member 40 , and adjacent limiting points 41 are connected by sliding inclined surfaces 42 .

[0029] The first restoring member 50 is used to push the rotating member 40 so that the limiting rib 111 abuts against a limiting point 41 thereof.

[0030] The second restoring member 60 is used to push the lens assembly 30 so that the slider 311 fits on one of the sliding inclined surfaces 42 thereof.

[0031] The force exerted by the first restoring member 50 on the rotating member 40 is greater than the force exerted by the second restoring member 60 on the rotating member 40 .

[0032] refer to Figures 1 to 6 Shown is a specific embodiment of the present invention.

[0033] The lens assembly 30 comprises a telescopic member 31 fitted in the active cavity 11 , an inner cover 32 mounted on the telescopic member 31 , and a lens 33 disposed between the telescopic member 31 and the inner cover 32 , wherein a slider 311 is disposed on the periphery of the telescopic member 31 .

[0034] The telescopic member 31 has a light-transmitting through hole 312 , the inner cover 32 is threadedly connected in the light-transmitting through hole 312 , and the pressed lens 33 is fitted in the light-transmitting through hole 312 .

[0035] The outer periphery of the telescopic member 31 is provided with a slide groove 313 arranged opposite to the limiting rib 111. The limiting rib 111 is slidably engaged in the slide groove 313 to limit the moving direction of the telescopic member 31 and ensure the stability of the product function.

[0036] The light source assembly 20 includes a base 21 mounted on one end of the active cavity 11 , a bracket 22 mounted on the base 21 , and a light source 23 disposed between the base 21 and the bracket 22 .

[0037] The base 21 is fixed to one end of the active cavity 11 by screws.

[0038] The bracket 22 is snap-connected to the base 21 , so the bracket 22 will not fall off easily during the installation process, thereby improving the installation efficiency.

[0039] The light source 23 is a COB light source.

[0040] The light source assembly 20 further includes a fixing ring 24 and a plurality of steel balls 25 disposed between the base 21 and the first reset member 50. The surface of the base 21 is formed with a plurality of steel ball grooves 211 disposed along the circumference of the base 21. The steel balls 25 are disposed one by one in each of the steel ball grooves 211. The fixing ring 24 is fitted on the surface of the steel balls 25 and connected to the first reset member 50. The provision of the steel balls 25 can make the rotation of the fixing ring 24 smoother and easier to operate, thereby optimizing the feel of the product when being adjusted.

[0041] The bracket 22 is located inside the fixing ring 24 , and there is a clearance fit between the two to prevent the bracket 22 from interfering with the rotation of the fixing ring 24 .

[0042] The surface of the fixing ring 24 is provided with an annular groove 241 for mounting the first restoring member 50 .

[0043] The other end of the movable cavity 11 protrudes inwardly along the radial direction of the movable cavity 11 to form a circle of limiting flange 112 , and the limiting flange 112 is used to install the second restoring member 60 .

[0044] Each group of limit points 41 includes a first limit point 41A, a second limit point 41B and a third limit point 41C of different heights. When the limit rib 111 abuts against the first limit point 41A, the second limit point 41B or the third limit point 41C, the beam angle of the lens 33 is 15°, 24° or 36°.

[0045] The first restoring member 50 and the second restoring member 60 are both springs.

[0046] refer to Figure 6 As shown, the working principle of the present invention is: the limit rib 111 is set to abut against the first limit point 41A of the rotating member 40 before adjustment, and the beam angle is 15°. When the user applies force to press the lens 33, the top of the slider 311 of the telescopic member 31 applies force to the sliding inclined surface 42, so that the rotating member 40 overcomes the elastic force of the first reset member 50 and moves toward the base 21 and disengages from the limit rib 111. At the same time, the component force generated by the sliding inclined surface 42 pushes the rotating member 40 to rotate, so that the limit rib 111 is aligned with the second limit point 41B (or the sliding inclined surface 42 between the first limit point 41A and the second limit point 41B) in the axial direction of the outer cover 10. When the user lets go of the lens 33, the first reset member 50 resets the rotating member 40 so that the limit rib 111 finally abuts against the second limit point 41B, and the beam angle of the lens 33 is adjusted. At this time, the beam angle is 24°.

[0047] Through the above structure, the present invention realizes the push-to-focus operation mode by setting a rotating member 40, a first reset member 50 and a second reset member 60. The rotating member 40 can be driven to rotate directly by pressing the lens assembly 30, so that the slider 311 of the lens assembly 30 can be matched at different positions of the rotating member 40, thereby realizing the change of the distance between the lens assembly 30 and the light source assembly 20, that is, completing the adjustment of different light beam angles, without disassembling the product, and the operation is simple and efficient.

[0048] In addition, one lens assembly 30 of the present invention can solve the angle problem of multiple ordinary lenses 33, the production cost can be greatly reduced, and the installation and production are simple and easy.

[0049] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
