Description

Technical Field

[0001] This utility model relates to the field of spotlight technology, specifically to a spotlight with adjustable focal length. Background Technology

[0002] A spotlight is a lighting device that uses a reflector or lens to focus light into a narrow, concentrated beam, thereby illuminating a specific area. These lights are commonly used in venues such as stages, photography studios, indoor studios, and shopping malls. Due to their powerful functionality and wide range of applications, their unique optical design allows them to create ideal lighting effects in various scenarios.

[0003] When the focus of a spotlight needs to be adjusted, the staff must first remove the spotlight from its place, then add or remove a lens, replace the lens module, or use it in conjunction with other lights to change the focus. This process is cumbersome and not conducive to the use of spotlights. Utility Model Content

[0004] The purpose of this invention is to provide a focal length adjustable spotlight to solve the above problems. It is driven by a drive mechanism and the focal length adjustment mechanism and the transmission mechanism work together to adjust the position of the T-shaped slider in the focal lens moving mechanism, thereby achieving the function of focal length adjustment.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] See Figures 1-5 As shown, this utility model provides a focal length adjustable spotlight, including: a handheld tube 1, a rubber ring 2 fixedly disposed on the outer side of the handheld tube 1, a focal length adjustment mechanism 3 fixedly disposed on one side of the handheld tube 1, a driving mechanism 4 disposed on one side of the inner bottom surface of the focal length adjustment mechanism 3, a transmission mechanism 5 disposed on the side of the inner bottom surface of the focal length adjustment mechanism 3 away from the handheld tube 1, and a focal length lens moving mechanism 6 disposed between the driving mechanism 4 and the transmission mechanism 5;

[0029] With the above technical solution, the handheld tube 1 and rubber ring 2 make it easy to hold the product and put it on a fixed place for irradiation. At the same time, the drive mechanism 4, through the transmission mechanism 5 and in cooperation with the focus adjustment mechanism 3, changes the position of the focus lens moving mechanism 6, so that the focus lens moving mechanism 6 can perform lateral reciprocating motion. The focus can be adjusted inside the product, eliminating the need to replace the lens, and the focus adjustment is more convenient.

[0030] See Figure 4 As shown, the focal lens moving mechanism 6 includes a T-shaped slider 601. Two support rods are fixedly installed on the bottom side of the T-shaped slider 601, and the two support rods are slidably installed on the bottom surface of the focal length adjustment mechanism 3. A zoom lens 602 is provided through one side of the T-shaped slider 601 at the top, and T-shaped support blocks 603 are fixedly installed on the front and rear sides of the T-shaped slider 601 at the bottom.

[0031] In use, two support rods are fixedly installed on the front and back of the bottom side of the T-shaped slider 601. As the T-shaped slider 601 moves laterally, it pushes the first angled transverse plate 304 and the second angled transverse plate 305 to one side, changing the direction of rotation of the motor 401 and adjusting the distance between the zoom lens 602 and the light tube 402, thereby changing the focal length. The T-shaped support block 603 and the threaded rod 502 are threaded together. The threaded rod 502 passes through the T-shaped support block 603. The two T-shaped support blocks 603 move laterally through the threaded engagement, thereby adjusting the focal length.

[0032] See Figure 4 and Figure 6 As shown, the driving mechanism 4 includes a motor 401, a light tube 402 fixedly mounted on one side above the motor 401, an output rod 403 fixedly mounted on one side of the motor 401, a drive gear 404 fixedly mounted on the body of the output rod 403, a connecting pipe 405 fixedly mounted on the outer side of the output rod 403 on one side of the motor 401, a turntable 406 rotatably mounted on one side of the connecting pipe 405, a transmission gear 407 rotatably mounted on one side of the turntable 406 near the top, output gears 408 rotatably mounted on both the front and rear sides of one side of the motor 401, a toggle lever 409 fixedly mounted on the lower rear side of the turntable 406, and rotation direction buttons 410 fixedly mounted on both the front and rear sides of one side of the motor 401.

[0033] In use, the light tube 402 provides a light source, the motor 401 drives the output rod 403 and the drive gear 404, and the output direction of the motor 401 is changed by the two rotation direction buttons 410, thereby adjusting the lateral position of the focus lens moving mechanism 6. The output rod 403 rotates the drive gear 404. When the transmission gear 407 on the turntable 406 falls on one of the two output gears 408, due to the heavy weight of the transmission gear 407, it meshes tightly with the output gear 408 in conjunction with the focus adjustment mechanism 3. A long rotating rod extends from one side of the transmission gear 407 to the rotation direction button 410. When the transmission gear 407 and the rotation direction button 410 are parallel, the extended rotating rod presses the rotation direction button 410. When it falls on one of the output gears 408, it supports the transmission gear 407 in conjunction with the drive gear 404, providing support while the weight of the transmission gear 407 completes the meshing, thereby driving the two different output gears 408 to rotate, and adjusting the position of the focus lens moving mechanism 6 in conjunction with the transmission mechanism 5.

[0034] See Figures 5-8 As shown, the focus adjustment mechanism 3 includes a supporting protective shell 301 and two second limiting plates 307. A first limiting plate 302 is fixedly disposed on the inner bottom surface of the supporting protective shell 301. A sliding groove 303 is formed on one side of the first limiting plate 302. A first angled transverse plate 304 and a second angled transverse plate 305 are symmetrically slidably disposed on the front and rear sides of the inner bottom surface of the supporting protective shell 301, respectively. One side of the first angled transverse plate 304 and the second angled transverse plate 305 slides inside the sliding groove 303. The first angled transverse plate 304 and the second angled transverse plate 305 are respectively slidably disposed on the front and rear sides of the inner bottom surface of the supporting protective shell 301. A connecting transverse plate 306 is fixedly installed on the side of the two-angle transverse plate 305 away from the first limiting plate 302. The connecting transverse plate 306 slides back and forth inside the two second limiting plates 307. A second limiting rod 309 is fixedly installed on the bottom surface of the supporting protective shell 301. A first limiting rod 308 is fixedly installed in the middle of one side of the connecting transverse plate 306. A swing plate 310 is provided between the first limiting rod 308 and the second limiting rod 309. A rotating limiting frame 311 is rotatably installed on the top side of the swing plate 310 near the focus adjustment mechanism 3 with a torsion spring.

[0035] In the above embodiment, the protective outer shell 301 protects the interior, and the two second limiting plates 307 restrict the movement of the connecting transverse plate 306. The first limiting plate 302, through a sliding groove 303 on one side, limits the first angled transverse plate 304 and the second angled transverse plate 305, so that the two angled transverse plates can only slide back and forth within the sliding groove 303 of the first limiting plate 302. The first angled transverse plate 304 and the second angled transverse plate 305 are symmetrically arranged. The angular transverse plate 305 is located on the side away from the first limiting plate 302 and is connected to the connecting transverse plate 306. During the transverse movement of the T-shaped slider 601 in the focal lens moving mechanism 6 via the transmission mechanism 5, the support rod on the bottom side of the T-shaped slider 601 pushes the angle of one of the angular transverse plates to one side. As one angular transverse plate moves, it carries the other angular transverse plate in the same direction. A slot is provided through one side of the connecting transverse plate 306, and the first limiting plate 305 is fixedly installed within the slot. The first limiting rod 308 moves along with the connecting transverse plate 306. During this movement, the first limiting rod 308 moves together with the connecting transverse plate 306. At this time, it works in conjunction with the second limiting rod 309 to change the angle of the swing plate 310 positioned between the two limiting rods. The rotation angle of the side of the swing plate 310 closest to the connecting transverse plate 306 is opposite to that of the other side. Through the rotating limiting frame 311 on the top side of the connecting transverse plate 306, it controls the actuating rod 4 on one side of the turntable 406 in the drive mechanism 4. The position of 09 is adjusted. When the swing plate 310 moves with the rotating limit frame 311, the rotating limit frame 311 rotates the turntable 406 through the toggle lever 409, so that the transmission gear 407 on the other side of the turntable 406 can be changed between the two output gears 408, and at the same time changed between the two rotation direction buttons 410, thereby changing the output direction of the motor 401 and the rotation direction of the different threaded rods 502, thereby changing the lateral movement direction of the focal lens moving mechanism 6, and thus changing the focal length.

[0036] See Figure 4 and Figure 5 As shown, the transmission mechanism 5 includes a C-shaped support plate 501. Threaded rods 502 are rotatably arranged through one side of the C-shaped support plate 501, both front and back. A rack is fixedly arranged on the side of the threaded rod 502 closest to the focus adjustment mechanism 3. A synchronous belt 504 is arranged between the other sides of the two threaded rods 502. A fixing rod 503 is fixedly arranged in the middle of one side of the C-shaped support plate 501.

[0037] Specifically, the C-shaped support plate 501 is set on the bottom surface of the support and protective shell 301 in the focus adjustment mechanism 3, and the C-shaped opening of the C-shaped support plate 501 faces downward. The threaded rod 502 passing through the front and rear sides of the C-shaped support plate 501 directly meshes with the output gear 408 through the rack of the rod body. When the motor 401 in the drive mechanism 4 drives any output gear 408 through the transmission gear 407, it directly drives the threaded rod 502 to rotate through the rack. Through the synchronous belt 504 on the other side of the rack of the threaded rod 502, the rotation direction of the two threaded rods 502 is consistent, ensuring that the T-shaped slider 601 in the focus lens moving mechanism 6 is driven to complete the focus adjustment.

[0038] Using the above structure, when the focal length of the spotlight needs to be adjusted, the operator opens the drive mechanism 4. The motor 401 in the drive mechanism 4 rotates the output rod 403, which in turn rotates the drive gear 404. The drive gear 404 transmits power to one of the two output gears 408 through the transmission gear 407. The output gear 408 rotates one of the threaded rods 502 through the rack on the rod body of the threaded rod 502 in the transmission mechanism 5. At this time, after the threaded rod 502 rotates, it will cause the other threaded rod 502 to rotate in the same direction through the synchronous belt 504 on one side of the threaded rod 502. This will drive the T-shaped support block 603 in the focal lens moving mechanism 6 to engage with the threaded drive, causing the T-shaped slider 601 between the two T-shaped support blocks 603 to move laterally, changing the distance between the zoom lens 602 and the light tube 402, thereby completing the focal length adjustment.

[0039] When the rod on the bottom side of the T-shaped slider 601 moves laterally to near the protruding angle of the first angled transverse plate 304, the rod on the bottom side of the T-shaped slider 601 pushes the protruding angle of the first angled transverse plate 304 backward, causing the first angled transverse plate 304 to move backward along with the second angled transverse plate 305 via the connecting transverse plate 306. During the movement, the first limiting rod 308 and the second limiting rod 309 on the inner side of the connecting transverse plate 306 change the angle of the swing plate 310. When moving backward, the side of the swing plate 310 away from the connecting transverse plate 306 moves forward, and when the connecting transverse plate 306 moves forward, the side of the swing plate 310 moves in the opposite direction. When the angle changes, the rotating limit frame 311, which is rotated on the top side of the swing plate 310, changes the position of the lever 409 on one side of the turntable 406, causing the turntable 406 to rotate. This causes the turntable 406 to rotate the transmission gear 407, making the transmission gear 407 mesh with one of the two output gears 408, driving the threaded rod 502. At the same time, the rod extending from one side of the transmission gear 407 presses the rotation direction button 410 on the side of the motor 401, changing the rotation direction of the motor 401, thereby changing the direction of the threaded rod 502. This allows the entire focal lens moving mechanism 6 to reciprocate between the drive mechanism 4 and the transmission mechanism 5, adjusting the focal length of the spotlight.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
