Description

Technical Field

[0001] This utility model relates to the field of LED secondary optical lens technology, specifically to a foolproof quick-change chuck for LED secondary optical lenses. Background Technology

[0002] LED lenses are optical systems used in conjunction with LEDs. Their core function is to adjust the light field distribution of the light source, improve luminous efficiency and focusing performance. They are widely used in automotive lighting, electronic equipment and commercial lighting. According to materials, they are divided into silicone (high temperature resistant encapsulation), PMMA (high light transmittance), PC (excellent temperature resistance) and glass (high precision). Structurally, they are divided into primary lenses integrated into the chip (adjusting the light emission angle) and independently installed secondary lenses (achieving precise light control).

[0003] Existing chucks lack effective support, making it difficult to maintain stability during placement. External vibrations can cause the chuck to wobble or shift, interfering with the normal operation of the LED secondary optical lens and compromising the overall stability of the device. During chuck installation, bolts are often used to secure the components, but precise fitting between parts is difficult, leading to installation difficulties and an unstable structure. Furthermore, when chuck replacement is needed for unlocking, simple and reasonable pressure cannot be used for quick unlocking, making the entire replacement process cumbersome, time-consuming, and labor-intensive, significantly reducing efficiency.

[0015] As attached Figure 1 To be continued Figure 4 As shown: This embodiment provides a foolproof quick-change chuck for LED secondary optical lenses, including a base 1, a sleeve 2 fixedly connected to the top of the base 1, two fixing blocks 3 fixedly connected to the surface of the sleeve 2, a circular block 4 provided at the top of the inner cavity of the fixing block 3, a short rod 5 fixedly connected to the bottom of the circular block 4, a sleeve block 6 slidably connected to the surface of the short rod 5, a hemispherical block 7 fixedly connected to the bottom of the short rod 5, a first elastic structure 8 provided at the bottom of the inner cavity of the sleeve 2, a second elastic structure 9 provided at the inner cavity of the fixing block 3, a chuck 10 fixedly connected to the top of the circular block 4, an LED secondary optical lens 11 provided at the top of the chuck 10, a mounting block 12 sleeved on the surface of the LED secondary optical lens 11, and the bottom of the mounting block 12 threadedly connected to the chuck 10.

[0016] Specifically, the first elastic structure 8 includes a circular plate 81 slidably connected to the bottom of the inner cavity of the sleeve 2. A first spring 82 is fixedly connected to the bottom of the circular plate 81. The other end of the first spring 82 is fixedly connected to the sleeve 2. Limiting grooves 83 are opened at the bottom of both sides of the inner cavity of the sleeve 2. Limiting blocks 84 are slidably connected to the inner cavity of the limiting grooves 83. One side of the limiting block 84 is fixedly connected to the circular plate 81.

[0017] In this embodiment, the first elastic structure 8 serves to support the chuck 10, and the elastic force of the first spring 82 makes the chuck 10 more stable when placed.

[0018] Specifically, the second elastic structure 9 includes a movable block 91 disposed in the inner cavity of the fixed block 3, a wedge block 92 fixedly connected to one side of the movable block 91, one side of the wedge block 92 penetrating into the inner cavity of the sleeve 2, a second spring 93 fixedly connected to one side of the movable block 91, and the other end of the second spring 93 fixedly connected to the fixed block 3.

[0019] In this embodiment: by setting the second elastic structure 9, when the chuck 10 is correctly installed, the wedge block 92 is squeezed and contracted into the inner cavity of the fixed block 3, so that the sleeve block 6 falls into the inner cavity of the hemispherical block 7. Then the chuck 10 moves upward, and through the squeezing force between the wedge block 92 and the round block 4, the wedge block 92 enters the inner cavity of the fixed block 3 again, so as to realize the quick unlocking of the chuck 10.

[0020] Specifically, the top and bottom of the inner cavity of the fixed block 3 are provided with sliding grooves 13, and the inner cavity of the sliding grooves 13 is slidably connected to sliders 14. The opposite sides of the two sliders 14 are fixedly connected to the movable block 91.

[0021] In this embodiment, the combined use of the slide groove 13 and the slider 14 serves to limit the movement of the movable block 91, thereby improving the stability of the movable block 91 during movement.

[0022] Specifically, the first spring 82 and the circular plate 81 form a telescopic structure. The maximum moving distance of the circular plate 81 is equal to the deformation of the first spring 82. One side of the circular plate 81 is in contact with the hemispherical block 7.

[0023] The working principle and usage process of this utility model: The user moves the chuck 10 downwards, which causes the circular block 4 to move downwards. The circular block 4 causes the short rod 5 to move, which in turn causes the sleeve block 6 to move. As the sleeve block 6 moves, it causes the circular plate 81 to move downwards. The circular plate 81 causes the limiting block 84 to slide downwards within the cavity of the limiting groove 83. As the circular plate 81 moves, it causes the first spring 82 to compress. When the short rod 5 moves downwards, it causes the sleeve block 6 to slide on its surface. When the top of the sleeve block 6 contacts the circular block 4, the downward pressing force of the chuck 10 causes the wedge block 92 to move to both sides. When the wedge block 92 moves, it will drive the movable block 91 to move in the inner cavity of the fixed block 3. When the movable block 91 moves, it will drive the second spring 93 to compress. When the wedge block 92 is completely inserted into the inner cavity of the fixed block 3, the sleeve block 6 will slide into the inner cavity of the hemispherical block 7 and engage with it. Then, by moving the chuck 10 upward, the user can move the round block 4, the short rod 5, the sleeve block 6 and the hemispherical block 7 upward. Through the squeezing force between the wedge block 92 and the round block 4, the wedge block 92 will re-enter the inner cavity of the fixed block 3, thereby realizing the quick unlocking of the chuck 10 and making it convenient for the user to replace the chuck 10.

[0025] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
