Description

Technical Field

[0001] This utility model relates to the field of lens device technology, specifically a lens device that can adjust the light from a condenser cup. Background Technology

[0002] A lens device is a device that utilizes the optical properties of lenses to achieve specific performance. Different numbers of lenses can be used in a synchronized combination to control the effect of the lens device. However, during use, it is inconvenient to adjust the position of the condenser cup inside the lens device, which affects the light usage effect.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application CN201720048397.0, filed on 2017-01-12) provides a lens structure that can achieve large-angle light adjustment. A light source channel extending from the lower end to the upper end is provided at the lower end of the LED lens. A connecting base is connected to the lower end of the LED lens, and an electric lifting platform is installed on the connecting base. An LED light source is installed on the lifting platform. The electric lifting platform drives the LED light source to rise or fall within the light source channel, thereby adjusting the position of the LED light source within the light source channel and thus adjusting the position of the LED light source within the LED lens, achieving the purpose of adjusting the light emission angle and realizing large-angle light adjustment. Although the prior art can achieve quantitative light adjustment, during operation, after adjusting the condenser cup, it is inconvenient to limit its movement, affecting the stability of the condenser cup. Furthermore, the gap between the lens body and the condenser cup body can easily cause unnecessary reflected light, affecting the stray light in the lens light and impacting image quality or light stability.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing lens devices. Utility Model Content

[0005] The purpose of this invention is to provide a lens device that can adjust the light from the condenser cup, in order to solve the problems mentioned in the background art, where it is inconvenient to limit and control the condenser cup after adjustment during operation, which affects the stability of the condenser cup, and the gap between the lens body and the condenser cup body can easily cause unnecessary reflected light, resulting in stray light in the lens light, affecting the image quality or the stability of the light.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lens device capable of adjusting the light from a condenser cup, comprising a lens holder for use with the lens device, and a lens body nested on the upper side of the inner surface of the lens holder; including: a slide rod, which is slidably connected to the inner surface of the lens holder, and a condenser cup holder is mounted on the outer surface of the slide rod; a lamp bead plate is mounted on the lower side of the inner surface of the condenser cup holder, and the condenser cup body is connected to the upper surface of the lamp bead plate; an adjustment frame is mounted on the lower side of the inner surface of the lens holder, and the adjustment frame is provided with a limit adjustment mechanism; a protective sheet, which is nested at the inner diameter of the inner surface of the condenser cup holder, and a spacer plate is attached to the outer surface of the protective sheet; the spacer plate is mounted on the upper side of the inner surface of the lens holder and located on the lower surface of the lens body; and the spacer plate is provided with a gap reflection mechanism.

[0007] Preferably, the lens mount forms a limiting sliding structure with the condenser cup mount via a slide rod, and the condenser cup mount and the lamp bead plate form a built-in nested structure, and the lens mount and the adjustment frame form an integrated structure.

[0008] The above structure facilitates the control of the stability of the focusing cup holder during use, prevents slippage, and provides stable support for the focusing cup body during irradiation.

[0009] Preferably, the limiting adjustment mechanism includes a worm gear rotatably connected to the side of the lower surface of the adjusting frame, and a worm wheel meshing with the outer surface of the worm gear, limiting the rotation of the worm wheel at the central axis of the lower surface of the adjusting frame. A rotating component is installed on the upper surface of the worm wheel, and the rotating component is provided with a limiting pressing mechanism. The adjusting frame forms a meshing rotation structure through the worm gear and the worm wheel, and the worm wheel and the rotating component form a rotation structure.

[0010] With the above structure, the rotation of the rotating parts can be controlled by the cooperation of the worm gear and worm during use, and a limit can be set after rotation to prevent spontaneous slippage.

[0011] Preferably, the limiting extrusion mechanism includes a connecting rod rotatably connected to the upper surface of the rotating component, and a slider rotatably connected to the outer side of the inner surface of the connecting rod, and a support rod rotatably connected to the upper side of the outer surface of the slider, while the upper surface of the support rod rotates on the lower surface of the condenser cup holder; the rotating component and the slider form a rotational extrusion structure through the connecting rod and the slider and the adjusting frame form a rotational structure, and the slider is set at an equal angle about the central axis of the inner surface of the adjusting frame, while the slider and the condenser cup holder form an extrusion support structure through the support rod.

[0012] With the above structure, during use, the rotation of the rotating component, in conjunction with the circumferential linear movement of the connecting rod and the slider, can adjust the up and down adjustment of the focusing cup holder by the support rod on the slider, thereby controlling the intensity of the light.

[0013] Preferably, the focusing cup holder forms a bonding structure with the spacer plate through the protective sheet, and the focusing cup holder forms a telescopic structure with the lens holder through the spacer plate.

[0014] With the above structure, it is easy to control the extension and retraction between the condenser cup holder and the lens holder through the spacer plate during use. The coating of the spacer plate reduces the influence of reflection and diffusion, and prevents damage to the rotating reflector when the condenser cup holder is extended or retracted.

[0015] Preferably, the gap reflective mechanism includes a ring nested on the inner surface of the spacer plate, and a reflector plate one and a reflector plate two rotatably connected to the outer surface of the ring plate. The reflector plate one and the reflector plate two are alternately arranged on the ring plate, and a pressing rod is installed on the rear side of the outer surface of the reflector plate two. Meanwhile, an elastic sheet is elastically connected between the reflector plate one and the reflector plate two and the spacer plate, and a retaining ring is connected to the lower side of the outer surface of the reflector plate one and the reflector plate two.

[0017] Preferably, the spacer plate forms an elastic rotation structure with reflector one and reflector two through a ring and an elastic sheet, and reflector two forms a compression structure with reflector one through a compression rod, and reflector one and reflector two form a limiting structure with the retaining ring.

[0018] The above structure improves the stability of reflector one and reflector two during rotation, enhances rotational linkage with the extrusion rod, and improves the stability of gap reflection light through the coating of both.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This lens device for adjusting the light from the condenser cup is equipped with a lens seat, which facilitates the sliding assembly of the condenser cup seat and the positioning and installation of the condenser cup body. It is also used in conjunction with the positioning and assembly adjustment frame to adjust the rotation of the rotating parts. In this way, the height of the condenser cup seat can be controlled by the connecting rod, slider and support rod, thereby adjusting the intensity of the light. Furthermore, the reflector plate 1 and reflector plate 2 on the spacer plate reduce the reflection and scattering at the gap expansion and contraction points.

[0021] 2. This lens device for adjusting the light from the condenser cup is equipped with a limit adjustment mechanism. The worm gear on the adjustment frame effectively controls the rotation of the rotating component on the worm wheel, thereby linking the linkage and other components on the rotating component to move in tandem. After movement, the meshing of the worm wheel and worm gear prevents shaking after adjustment. Furthermore, a limit pressing mechanism is provided, facilitating circumferential linear movement through the rotation of the rotating component to control the position of the slider and control the support rod to press and lift the condenser cup seat, improving its lifting stability and increasing the gap between the condenser cup body and the lens body, thus controlling the stability of gap adjustment.

[0022] 3. This lens device, which can adjust the light from the condenser cup, is equipped with a gap reflection mechanism. The angle of reflector one and reflector two can be controlled by the extension and retraction of the spacer plate mounted on the lens mount and the condenser cup mount. When used for gap adjustment, the reflection at the gap position is controlled to reduce light scattering. Furthermore, the use of protective plates, elastic plates, retaining rings and compression rods increases the safety of the extension and retraction of reflector one and reflector two, reduces wear, and allows for automatic deployment while avoiding excessive elastic deployment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-7 The present invention provides the following technical solution: a lens device that can adjust the light of a condenser cup, wherein a lens holder 1 is provided for use by the lens device, and a lens body 2 is nested on the upper side of the inner surface of the lens holder 1.

[0033] Example 1: As Figures 1-5 The present invention provides the following technical solution: a lens device for adjusting the light from a condenser cup, comprising: a slide rod 3, which is slidably connected to the inner surface of a lens holder 1; a condenser cup holder 4 is mounted on the outer surface of the slide rod 3; a lamp bead plate 5 is mounted on the lower side of the inner surface of the condenser cup holder 4; a condenser cup body 6 is connected to the upper surface of the lamp bead plate 5; and an adjustment frame 7 is mounted on the lower side of the inner surface of the lens holder 1, with a limiting adjustment mechanism provided on the adjustment frame 7; the lens holder 1 and the condenser cup holder 4 form a limiting sliding structure through the slide rod 3; the condenser cup holder 4 and the lamp bead plate 5 form an internal nested structure; and the lens holder 1 and the adjustment frame 7 form an integrated structure.

[0034] In use, the lens body 2 is nested and assembled on the upper side of the lens holder 1 to control the stable illumination of light. The sliding rod 3 installed in the condenser cup holder 4 stabilizes the sliding of the condenser cup holder 4 within the lens holder 1, preventing shaking during movement and preventing changes in the light angle. Furthermore, the use of the lamp bead plate 5 built into the condenser cup holder 4 and the condenser cup body 6 improves the illumination and reflection of light, thereby enhancing the light usage effect.

[0035] Example 2: Figures 1-5The technical solution shown, based on Embodiment 1, further discloses a method for adjusting the distance between the condenser cup holder 4 and the lens body 2 controlled by the adjusting frame 7. The specific details are as follows: The limiting adjustment mechanism includes a worm gear 8 rotatably connected to the lower surface of the adjusting frame 7, and a worm wheel 9 meshing with the outer surface of the worm gear 8, limiting the rotation of the worm wheel 9 at the central axis of the lower surface of the adjusting frame 7. A rotating component 10 is mounted on the upper surface of the worm wheel 9, and the rotating component 10 is equipped with a limiting pressing mechanism. The adjusting frame 7 forms a meshing rotation structure through the worm gear 8 and the worm wheel 9, and the worm wheel 9 and the rotating component 10 form a rotational structure. The limiting extrusion mechanism includes a connecting rod 11 rotatably connected to the upper surface of the rotating component 10, and a slider 12 rotatably connected to the outer side of the inner surface of the connecting rod 11. A support rod 13 is rotatably connected to the upper side of the outer surface of the slider 12, and the upper surface of the support rod 13 rotatably rests on the lower surface of the focusing cup seat 4. The rotating component 10 and the slider 12 form a rotation extrusion structure through the connecting rod 11, and the slider 12 and the adjusting frame 7 form a rotation structure. The slider 12 is set at an equal angle to the central axis of the inner surface of the adjusting frame 7, and the slider 12 and the focusing cup seat 4 form an extrusion support structure through the support rod 13.

[0036] When adjusting the telescopic cup holder 4, the motor assembled on the lower side of the adjustment frame 7 mounted on the lens holder 1 is activated, and the output shaft drives the worm gear 8 to rotate, which in turn meshes with the adjusting worm wheel 9 to rotate. This causes the rotating component 10, which is assembled on the rotating shaft mounted on the worm wheel 9, to rotate synchronously. The off-axis assembled on the rotating component 10 effectively drives the connecting rod 11 to press the slider 12 to move in a circular linear motion within the adjustment frame 7. This controls the slider 12 to move linearly on the inner surface of the adjustment frame 7. When the slider 12 moves, it presses the support rod 13 to control the telescopic cup holder 4 to move up and down on the inner surface of the lens holder 1, thereby controlling the intensity of the light and improving the stability of the light adjustment.

[0037] Example 3: Figure 1 , Figure 2 , Figure 6 and Figure 7The technical solution shown, based on Embodiment 2, further discloses the control of reflection at the gap during the telescopic adjustment between the condenser cup holder 4 and the lens holder 1. The specific details are as follows: A protective sheet 14 is nested and installed on the inner diameter of the inner surface of the condenser cup holder 4, and a spacer 15 is attached to the outer surface of the protective sheet 14. The spacer 15 is installed on the upper side of the inner surface of the lens holder 1 and located on the lower surface of the lens body 2. The spacer 15 is provided with a gap reflection mechanism. The condenser cup holder 4 forms a fitting structure with the protective sheet 14 and the spacer 15, and the condenser cup holder 4 forms a telescopic structure with the lens holder 1 through the spacer 15. The gap reflection mechanism includes a ring 16 nested and connected to the inner surface of the spacer 15. Reflector 17 and Reflector 28 are rotatably connected to the outer surface of ring 16, and reflector 17 and Reflector 28 are alternately arranged on ring 16. A pressing rod 19 is installed on the rear side of the outer surface of reflector 28. Meanwhile, an elastic sheet 20 is elastically connected between reflector 17, Reflector 28 and spacer 15. A retaining ring 21 is connected to the lower side of the outer surface of reflector 17 and Reflector 28. Spacer 15 forms an elastic rotation structure with reflector 17 and Reflector 28 through ring 16 and elastic sheet 20. Reflector 28 forms a pressing structure with reflector 17 through pressing rod 19. Reflector 17 and Reflector 28 form a limiting structure with retaining ring 21.

[0038] When adjusting the telescopic movement between the lens mount 1 and the condenser cup mount 4, the spacer plate 15, which controls the lens mount 1, is stably telescopically extended and retracted within the condenser cup mount 4. This works in conjunction with the protective sheet 14 built into the condenser cup mount 4 to prevent friction damage to the spacer plate 15. When the distance between the lens body 2 and the condenser cup body 6 increases, the elastic sheet 20 in the spacer plate 15 causes the elastic compression ring 16 to rotate, angulating the reflector plate 17 and reflector plate 18. This, along with the compression rod 19 installed on the reflector plate 18, prevents interference during the synchronous rotation of the reflector plate 17 and reflector plate 18. The retaining ring 21 installed on the spacer plate 15 prevents the reflector plate 17 and reflector plate 18 from over-rotating, improving the convenience of reflection control. Furthermore, the coating of the spacer plate 15, reflector plate 17, and reflector plate 18 enhances reflection stability, reduces light diffusion, and improves the stability of light adjustment.

[0039] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
