Description

Technical Field

[0001] This utility model specifically relates to a toy image projection testing device. Background Technology

[0002] As toys serve as important tools for children's intellectual development and entertainment, people's demands for the quality and functionality of toys are constantly increasing with the improvement of living standards. When choosing toys, people prefer toys with good scientific and fun features. Existing toys are loved by many children. However, current toys generally only focus on the shape, such as designing them into various animal shapes or Q-version figures, but their core function is still only decoration, lacking other creative features.

[0003] Therefore, manufacturers place image films inside toys so that children can discover more playability through projection. However, during the toy manufacturing and assembly process, it is necessary to check whether the image film is installed or to determine whether the placed image film corresponds to the image in the instruction manual. This requires projection testing to eliminate toys that do not have image films or have the wrong image films. To address this, we provide a toy image projection testing device to solve the problems mentioned in the background art. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a toy image projection testing device.

[0012] Preferably, the fixture base includes a base, a fixed clamp plate with screw holes welded to the upper middle part of the base, an arc-shaped groove opened on the upper end of one side of the fixed clamp plate, a movable clamp plate fixed to the fixed clamp plate by screws, and the lower end of the condenser lens is inserted into the arc-shaped groove. The fixed clamp plate and the movable clamp plate are then used to fix the lens.

[0013] Preferably, the focusing lens is a convex lens.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The adjustment precision of the projection panel can be improved by the cooperation of the lead screw and lead screw nut. The position of the projection panel can be precisely controlled as needed to ensure the clarity and accuracy of the image projection. Moreover, the design of the lead screw and the groove on the base plate can prevent the lead screw nut from contacting the base plate, reduce friction, and ensure smooth sliding of the projection panel.

[0016] 2. Triangular reinforcing ribs and guide sliders are welded to both sides of the projection panel, which enhances the rigidity and stability of the projection panel and avoids the projection effect from deterioration due to vibration or instability during movement. The fixture seat adopts a fixed clamping plate and movable clamping plate structure, which can firmly fix the condenser lens and avoid the image quality from being affected by the lens loosening.

[0017] 3. Aligning the projector lamp, focusing lens, and projection aperture reduces light scattering, improves projection clarity, and ensures effective light transmission, resulting in a clearer projection effect. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0024] Example

[0025] A toy image projection testing device, such as Figure 1-5 As shown, it includes a projection box 1, a light source 2, a fixture 3, and a focusing lens 4.

[0026] The projection box 1 includes a base plate 11, a box body 12 fixedly installed at one end above the base plate 11, a box cover 13 fixedly installed on the box body 12, a lead screw 14 installed above the base plate 11 and located inside the box body 12, and a projection plate 15 assembled with the lead screw 14 and located inside the box body 12; the light source 2 is fixed on the base plate 11, and the clamp seat 3 is fixedly installed on the base plate 11 and located between the light source 2 and the box body 12 for fixing the condenser lens 4.

[0027] The base plate 11 has a strip groove 111 corresponding to the lead screw 14. The front end of the housing 12 has a projection hole 121, and the projection hole 121 is the same as the axis of the condenser lens 4. The inner walls on both sides of the housing 12 have guide grooves 122.

[0028] The front end of the cover 13 is provided with an observation hole 131, which allows real-time viewing of the projection effect without the need for frequent opening of the cover, thus improving testing efficiency.

[0029] A lead screw nut 151 is welded to the bottom of the projection plate 15, and triangular reinforcing ribs 152 are welded to both sides of the projection plate 15. Guide sliders 153 are welded to the middle of both sides of the projection plate 15, and the guide sliders 153 are embedded in the guide grooves 122 with a clearance fit. Specifically, the lower end of the lead screw nut 151 falls into the strip groove 111, so that when the drive screw 14 adjusts the movement of the projection plate 15, the lead screw nut 151 does not contact the base plate 11, thus preventing it from affecting the sliding. Specifically, the triangular reinforcing ribs 152 and guide sliders 153 welded to both sides of the projection plate 15 enhance the rigidity and stability of the projection plate 15, preventing the projection effect from deteriorating due to vibration or instability during movement.

[0030] It should be further explained that the cooperation between the lead screw 14 and the lead screw nut 151 can improve the adjustment accuracy of the projection plate 15, accurately control the position of the projection plate as needed, and ensure the clarity and accuracy of the image projection. Moreover, the design of the lead screw 14 and its cooperation with the strip groove 111 on the base plate 11 can prevent the lead screw nut 151 from contacting the base plate 11, reduce friction, and ensure that the projection plate 15 slides smoothly.

[0031] The light source 2 includes a support plate 21 and a projection lamp 22 embedded in the middle part of the support plate 21; the optical axis of the projection lamp 22 is aligned with the center of the focusing lens 4.

[0032] It should be further explained that the projection lamp 22, the focusing lens 4, and the projection hole 121 of the light source 2 are aligned to reduce light scattering and improve projection clarity.

[0033] The clamp base 3 includes a base 31, a fixed clamping plate 32 with screw holes welded to the upper center of the base 31, an arc-shaped groove 33 on the upper side of the fixed clamping plate 32, and a movable clamping plate 34 fixed to the fixed clamping plate 32 by screws. The lower end of the condenser lens 4 is inserted into the arc-shaped groove 33, and then fixed by the cooperation of the fixed clamping plate 32 and the movable clamping plate 34. Specifically, the clamp base 3 is fixed by screws to the arc-shaped groove 33 and the movable clamping plate 34, enabling tool-free quick replacement of the condenser lens 4, facilitating cleaning or adaptation to different lenses.

[0034] In this embodiment, the focusing lens 4 is a convex lens. Specifically, the focusing lens 4 is a convex lens, which effectively converges light, enhances projection brightness and contrast, and is especially suitable for low-power toy light sources.

[0035] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
