[0025] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-6 As shown, this utility model provides a technical solution: a focal length adjustable LED light source focusing device, including a lamp barrel 1, a focusing cover 2 fixedly installed on the upper part of the lamp barrel 1, and a connecting assembly 3 disposed between the lamp barrel 1 and the focusing cover 2. The connecting assembly 3 includes a protective mechanism 31 disposed between the lamp barrel 1 and the focusing cover 2. An adjustment mechanism 32 is disposed inside the lamp barrel 1. The protective mechanism 31 includes a mounting groove 311 opened at the top. A mounting frame 312 is inserted into the mounting groove 311. A transparent plate 313 is fixedly installed inside the mounting frame 312. A sliding groove 314 is opened on the outer wall of the focusing cover 2. A sliding rod 315 is fixedly connected to the inner wall of the sliding groove 314. A slider 316 is slidably connected to the outer wall of the sliding rod 315. A first spring 317 is fixedly connected to the inner wall of the sliding groove 314. The outer side of the slider 316 is fixed. A limit rod 318 is connected to the inner wall of the focusing cover 2, a sealing ring 319 is fixedly connected to the inner wall of the mounting groove 311, a first inner groove 3110 is opened in the inner wall of the mounting groove 3110, an ejector post 3111 is movably connected inside the first inner groove 3110, a second spring 3112 is fixedly connected to the inner wall of the first inner groove 3110, a placement groove 3113 is opened on one side of the lamp tube 1, a heat dissipation hole 3119 is opened in the inner wall of the placement groove 3113, a connecting frame 3114 is snapped into the placement groove 3113, a dustproof net 3120 is fixedly installed inside the connecting frame 3114, a pressing groove 3115 is opened on the side wall of the connecting frame 3114, a second inner groove 3116 is opened in the inner wall of the placement groove 3113, a pressing post 3117 is movably connected inside the second inner groove 3116, and a third spring 3118 is fixedly connected to the inner wall of the second inner groove 3116.

[0028] In this embodiment, one end of the first spring 317 is fixedly connected to the slider 316, and the inner side of the limiting rod 318 is fitted to the outer side of the mounting frame 312. Through the cooperation of the mounting groove 311, mounting frame 312, transparent plate 313, sliding groove 314, sliding rod 315, slider 316, first spring 317, limiting rod 318, sealing ring 319, first inner groove 3110, ejector post 3111, and second spring 3112, the focusing cover 2 can be sealed, thereby protecting the LED lamp 323. It also facilitates manual disassembly of the mounting frame 312, which facilitates subsequent manual inspection and maintenance of the LED lamp 323, increasing the applicability of the device.

[0029] Furthermore, the sealing ring 319 is set in the gap between the mounting groove 311 and the mounting frame 312. One end of the second spring 3112 is fixedly connected to the ejector post 3111. Through the cooperation of the placement groove 3113, the connecting frame 3114, the pressing groove 3115, the second inner groove 3116, the pressing post 3117, the third spring 3118, the heat dissipation hole 3119, and the dustproof net 3120, external dust and impurities can be prevented from entering the lamp tube 1 through the heat dissipation hole 3119. The dustproof net 3120 is easy to disassemble and clean manually, which can prevent the filter holes of the dustproof net 3120 from being blocked and affecting subsequent use.

[0030] Furthermore, one end of the third spring 3118 is fixedly connected to the pressing post 3117, and the pressing post 3117 is in pressing contact with the pressing groove 3115.

[0031] When in use, the device, through the cooperation of the mounting frame 312 and the transparent plate 313, can seal the port of the focusing cover 2, thereby protecting the LED light 323. Furthermore, when it is necessary to disassemble the mounting frame 312, simply push the limiting rod 318 manually. Under the limiting action of the sliding rod 315 and the slider 316, the limiting rod 318, which is fixedly connected to the outside of the slider 316, can move away from the outside of the mounting frame 312. Then, under the action of the elastic force of the second inner groove 3116, the ejector column 3111 can push the mounting frame 312 outward, thereby ejecting the mounting frame 312 outward, and further... The installation frame 312 is easily removed manually, allowing for subsequent cleaning of the transparent plate 313. This facilitates manual inspection and maintenance of the LED light 323, increasing the device's versatility. When installing the dustproof net 3120 after cleaning, the connecting frame 3114 is simply inserted manually into the placement groove 3113. Then, the third spring 3118, under its elastic force, causes the pressing column 3117 to press against the pressing groove 3115, thus fixing the connecting frame 3114 in the placement groove 3113. This completes the installation of the connecting frame 3114 and the dustproof net 3120, making the operation simple and convenient.

[0032] Example 2

[0033] Based on Embodiment 1, a preferred embodiment of the focal length adjustable LED light source focusing device provided by this utility model is, for example... Figures 1 to 6 As shown: The adjustment mechanism 32 includes an electric telescopic rod 321 fixedly installed inside the light-concentrating cover 2. The output end of the electric telescopic rod 321 is fixedly connected to a support plate 322. An LED light 323 is fixedly installed on the upper part of the support plate 322. A limit post 324 is fixedly installed inside the light tube 1. A limit block 325 is fixedly connected to the top of the limit post 324.

[0034] In this embodiment, the support plate 322 is slidably connected to the outer wall of the limiting post 324. Through the cooperation of the electric telescopic rod 321, the support plate 322, the LED light 323, the limiting post 324, and the limiting block 325, the position of the LED light 323 can be adjusted, thereby adjusting the focal length and further increasing the applicability of the device.

[0035] When the focus needs to be adjusted, the electric telescopic rod 321 drives the support plate 322 to move up or down. Since the LED light 323 is fixedly installed on the upper part of the support plate 322, the position of the LED light 323 can be adjusted. Under the action of the condenser cover 2, the focus can be adjusted. Under the action of the limiting post 324 and the limiting block 325, the support plate 322 can be limited, thus making the support plate 322 more stable during use.
