Description

Technical Field

[0001] This utility model relates to the field of laser toy technology, and in particular to a dual-color laser pointer. Background Technology

[0002] In existing technologies, to make laser pointers more interesting, a conversion plate is usually set at the head of the laser pointer. When the laser passes through the convex lens and the conversion plate, it projects a corresponding pattern, thus achieving the desired fun. For example, Chinese utility model patent application number 202421620235.6 discloses an electric laser pet toy, including a laser pointer. One side of the laser pointer has a threaded connecting post, and a USB plug is fixedly connected to the side wall of the threaded connecting post. The USB plug is electrically connected to the laser pointer, and a threaded cylinder is threadedly connected to the side wall of the threaded connecting post. The laser pointer has a laser diode fixedly connected to one end away from the threaded connecting post. A fixing ring is fixedly connected to the end of the laser pointer located outside the laser diode. An end cap is rotatably connected to the side wall of the fixing ring. A connecting piece is fixedly connected to the end of the end cap away from the laser pointer. Multiple conversion pieces are fixedly connected inside the connecting piece. However, because different colors of light have different wavelengths and refractive indices, if laser emitters of different colors are placed at the same distance from a convex lens, the projected patterns will be of different sizes and have inconsistent proportions. As a result, currently only monochrome laser pointers are available on the market. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a dual-color laser pointer. By installing an assembly rack on the front side of the circuit board, laser emitters of different colors can be locked in different positions, so that their light can be focused on the same position, so that they can simultaneously project patterns of different colors with coordinated size proportions.

[0004] This utility model discloses a dual-color laser pointer, comprising a housing, on which a conversion plate, a convex lens, a laser lamp, and a circuit board are sequentially arranged along its axial direction. The housing also has a battery for power supply and a control switch for driving the laser lamp. Both the battery and the control switch are electrically connected to the circuit board. The key feature is that an assembly frame is provided between the circuit board and the convex lens. The laser lamp includes a lamp body I and a lamp body II with different color light sources. Lamp body I is fixed on the assembly frame and electrically connected to the circuit board. When lamp body I is fixed on the assembly frame, the distance of lamp body II is adjusted and it is fixed on the assembly frame so that the light sources of lamp body I and lamp body II are focused at the same position by the convex lens.

[0005] A further feature of this invention is that a spring is provided between the assembly frame and the convex lens, with one end of the spring abutting against the assembly frame and the other end abutting against the convex lens.

[0006] A further feature of this invention is that it includes a replacement head, which comprises a rotating part and a connecting part. The connecting part is threadedly connected to the housing, and a bearing is also sleeved on the connecting part. The rotating part is rotatably sleeved on the bearing, and a conversion plate is disposed on the rotating part.

[0007] A further feature of this invention is that the housing is also equipped with an assembly, in which a convex lens, a spring, and an assembly frame are sequentially assembled to form a dual-color laser module. The tail of the assembly frame abuts against the circuit board, and the circuit board is fixedly mounted on the housing.

[0008] A further feature of this invention is that anti-slip textures are provided on the outer sides of both the rotating part and the connecting part.

[0009] Using the above technical solution, the mounting frame allows lamp body I and lamp body II to be installed at a distance different from that of the convex lens, so that different wavelengths can have the same focal point, making the size ratio of the projected pattern coordinated, and thus allowing one pattern to project two colors.

[0016] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] This utility model discloses a dual-color laser pointer, including a housing 1. A conversion plate 2, a convex lens 3, a laser lamp 4, and a circuit board 5 are sequentially arranged along the axial direction of the housing 1. The housing 1 also has a battery 6 for power supply and a control switch 7 for driving the laser lamp 4. Both the battery 6 and the control switch 7 are electrically connected to the circuit board 5. In this embodiment, an assembly frame 8 is provided between the circuit board 5 and the convex lens 3. The laser lamp 4 includes a lamp body I41 and a lamp body II42 that can emit different colored light sources (lamp body I41 preferably emits a red light source, and lamp body II42 preferably emits a green light source, but can also emit yellow, purple, etc.). Lamp body I41 is fixed on the assembly frame 8 and electrically connected to the circuit board 5. When lamp body I41 is fixed on the assembly frame 8, the distance of lamp body II42 is adjusted and it is fixed on the assembly frame 8 so that the light sources of lamp body I41 and lamp body II42 are focused at the same position by the convex lens 3. This adjustment and assembly are performed and set by the manufacturer at the factory.

[0019] By adopting the above technical solution, the mounting bracket 8 allows the lamp body I41 and lamp body II42 to be installed at a distance different from that of the convex lens 3, so that different wavelengths can have the same focal point, making the size ratio of the projected pattern coordinated, and thus allowing one pattern to project two colors.

[0020] A spring 9 is provided between the mounting bracket 8 and the convex lens 3. One end of the spring 9 abuts against the mounting bracket 8 and the other end abuts against the convex lens 3. The mounting bracket 8 facilitates the installation and adjustment of the lamp body I41 and lamp body II42, and also facilitates the pressing of the spring 9, making the convex lens 3 more stable during use.

[0021] It also includes a replacement head 10, which includes a rotating part 101 and a connecting part 102. The connecting part 102 is threadedly connected to the housing 1, and a bearing is also fitted on the connecting part 102 (the specific structure of the bearing is not shown in the diagram, but it can be ordered from the market and will not be described in detail here). The rotating part 101 is rotatably fitted on the bearing, and the conversion plate 2 is set on the rotating part 101. When the connecting part 102 rotates and separates from the housing 1, the replacement head 10 can be replaced, which is convenient for maintenance or replacement of patterns of other groups. When the rotating part 101 rotates relative to the housing 1, the projected pattern can be replaced. The bearing facilitates the rotation of the rotating part 101.

[0022] The housing 1 is also equipped with a mounting kit 20. The convex lens 3, spring 9, and mounting bracket 8 are sequentially assembled in the mounting kit 20 to form a dual-color laser module. The tail of the mounting bracket abuts against the circuit board 5, and the circuit board 5 is fixedly mounted on the housing 1. Using the mounting kit 20 for assembly makes the assembly more stable and the internal structure more compact. When the tail of the mounting bracket 8 abuts against the circuit board 5, the spring 9 can simultaneously push the convex lens and the mounting kit against the housing to prevent the dual-color laser module from shaking.

[0023] The outer sides of the rotating part 101 and the connecting part 102 are provided with anti-slip textures 30, which can facilitate the rotation of the rotating part 101 and the connecting part 102 and prevent slippage.
