Description

Technical Field

[0001] This invention relates to color detection and quality control technology, and more particularly to a standard light source observation box for color comparison. Background Technology

[0002] In the production processes of industries such as textiles, printing, and plastics, color comparison is a crucial step in ensuring consistent product quality. It requires the use of standard light source observation equipment to simulate lighting conditions under different environments, ensuring that product colors appear consistently in various scenarios. Traditional color comparison equipment often employs a fixed light source or a single rotating platform design, which has significant limitations: fixed light source equipment can only illuminate the object from a single angle, easily resulting in localized shadows or uneven lighting, leading to misjudgments of color differences by operators; while a single rotating platform allows adjustment of the observation angle, it cannot accommodate vertical movement of the object, and for three-dimensional objects or objects with uneven surfaces, blind spots remain, affecting comparison accuracy.

[0003] Furthermore, traditional equipment often relies on manual rotation of the light source assembly for angle adjustment, resulting in low precision and difficulty in maintaining stability. Even slight touches can cause the light source to shift, requiring repeated calibration. Deceleration control typically involves manually pushing friction blocks, which is difficult to control, leading to sudden drops in speed or incomplete deceleration, affecting the stability of the moving objects. Simultaneously, most traditional equipment lacks effective dustproof structures, allowing dust to accumulate internally over time, adhering to the light source or platform. This not only affects light intensity and color reproduction but also accelerates component wear, shortening the equipment's lifespan. These problems result in low color comparison efficiency and poor precision in traditional equipment, failing to meet the high standards and efficiency required for product quality control in modern production. There is an urgent need for a standard light source observation device that enables multi-dimensional movement of objects, precise adjustment of the light source and deceleration, and dustproof functionality to improve the accuracy and efficiency of color comparison and ensure product quality stability. Summary of the Invention

[0004] Purpose of the invention: The purpose of this invention is to ensure the stability of the movement of the object, reduce the frequency of manual adjustment by the operator, and ultimately improve the accuracy of color comparison and the convenience of operation; another purpose of this invention is to provide a precise deceleration mechanism and a convenient light source disassembly and replacement function.

[0005] Technical solution: A standard light source observation box for color comparison includes a box body, the inside of which is provided with a circular groove, a rotating cavity is fixedly connected inside the circular groove, a shelf is fixedly connected to the upper surface of the rotating cavity, and a rotating slot is provided on the upper surface of the box body, a lamp holder is rotatably connected inside the rotating slot.

[0006] Furthermore, a motor is fixedly connected inside the rotating cavity, and a fixed rod is fixedly connected to the output end of the motor. An outer cavity is slidably connected to the outer wall of the fixed rod. Limiting grooves are symmetrically formed on the inner side wall of the outer cavity. Limiting strips are symmetrically fixedly connected to the outer side wall of the fixed rod. The limiting strips are slidably connected to the limiting grooves. The top end of the outer cavity extends above the rotating cavity and is fixedly connected to the lower surface of the shelf.

[0007] Furthermore, a guide block is fixedly connected to the outer wall of the outer cavity, and a guide groove is provided inside the rotating cavity, with the guide block slidably connected to the inside of the guide groove.

[0008] Furthermore, the bottom end of the motor's output terminal extends through to the bottom of the rotating cavity and is fixedly connected to a rotating cylinder. The rotating cylinder is slidably connected to the outer wall of the rotating cavity. A transverse cavity is fixedly connected to the right side of the lower surface of the box body. A sliding plate is slidably connected inside the transverse cavity. An extension rod is fixedly connected to the left end of the sliding plate. The left end of the extension rod extends through to the left end of the transverse cavity and is fixedly connected to a deceleration arc ring. A sliding rod is symmetrically rotatably connected to the inner wall of the deceleration arc ring.

[0009] Furthermore, the outer wall of the transverse cavity is symmetrically provided with transverse sliding grooves, and the outer wall of the slide plate is symmetrically fixedly connected with U-shaped plates. The U-shaped plates are slidably connected to the outer wall of the transverse cavity, and the left end of the U-shaped plates is fixedly connected with an electric telescopic rod, which is fixedly connected to the lower surface of the transverse cavity.

[0010] Furthermore, the outer wall of the lamp cavity is symmetrically provided with lamp slots, and a standard light source is fixedly connected inside each lamp slot. A small gear is rotatably connected to the right side of the outer wall of the box, and a long rod is fixedly connected to the left side of the small gear. The long rod is fixedly connected to the lamp cavity. A large gear is rotatably connected to the right side of the box, and the large gear meshes with the small gear.

[0011] Furthermore, a locking opening is provided on the outer side wall of the large gear, and a positioning opening is symmetrically provided on the right side of the box body, located on the left side of the large gear. A rotating plate is fixedly connected to the outer side wall of the large gear, and a spring cavity is fixedly connected to the front surface of the rotating plate.

[0012] Furthermore, a locking rod is slidably connected inside the cartridge cavity. The locking rod passes through the locking port and engages with the positioning port. A central rod is fixedly connected to the upper surface of the locking rod. The top end of the central rod extends through to the outer wall of the cartridge cavity. A spring coil is wound around the outer wall of the central rod inside the cartridge cavity.

[0013] Furthermore, the front surface of the box has an opening, and the upper surface of the box has an upper slot, with a dustproof glass slidably connected inside the upper slot.

[0014] Beneficial Effects: This standard light source observation box, through its multi-structure collaborative design, significantly improves the accuracy and ease of operation of color comparison. In terms of object movement control, the optimized structure of the fixed rod and outer cavity allows the limit strip to slide, driving the shelf to move up and down and rotate synchronously. This ensures that all parts of the object to be compared receive uniform light illumination, avoiding the uneven lighting problems caused by traditional equipment that can only rotate or be fixed in place. This reduces blind spots in color observation. Regarding the light source adjustment, multiple standard light sources are fixed in the lamp slots of the lamp cavity, allowing for switching of light source types as needed. Combined with the meshing transmission of large and small gears, the light source illumination angle can be precisely adjusted. Furthermore, the locking rod and positioning port stabilize the light source angle, preventing offset after adjustment from affecting the comparison results. In addition, the electric telescopic rod-driven deceleration structure replaces the traditional manual deceleration method, precisely controlling the drum speed and further ensuring the stability of object movement. This eliminates the need for frequent manual adjustments by operators, significantly improving operational efficiency.

[0015] The equipment's dustproof and structural protection design effectively ensures internal cleanliness and extends its service life. A dustproof glass panel slides through a slot on the upper surface of the housing, covering the opening during daily use to prevent dust and impurities from entering the housing. This prevents dust from adhering to the shelf surface or the lampshade of the standard light source, affecting the color reproduction of items and the intensity of the light source, ensuring that color matching accuracy remains unaffected during long-term use. Simultaneously, the guiding and protective structures for each moving component also contribute to extending its lifespan: the guide block on the outer side of the outer cavity slides along the guide groove of the rotating cavity, preventing wobbling during rotation and thus preventing component wear; the U-shaped plate slides along the transverse groove of the transverse cavity, ensuring stable movement of the sliding plate and reducing frictional wear between the inner wall of the transverse cavity and the sliding plate. These designs reduce the probability of component failure, decrease maintenance frequency, and significantly extend the overall service life of the equipment. Attached Figure Description

Detailed Implementation

[0024] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example

[0026] like Figures 1-7 As shown, a standard light source observation box for color comparison is provided, including a box body 1. A circular groove 2 is formed inside the box body 1. A rotating cavity 3 is fixedly connected inside the circular groove 2. A shelf 4 is fixedly connected to the upper surface of the rotating cavity 3. A rotating slot 5 is formed on the upper surface of the box body 1. A lamp-holding cavity 6 is rotatably connected inside the rotating slot 5. A motor 7 is fixedly connected inside the rotating cavity 3. A fixing rod 8 is fixedly connected to the output end of the motor 7. An outer cavity 9 is slidably connected to the outer wall of the fixing rod 8. Limiting grooves 10 are symmetrically formed on the inner wall of the outer cavity 9. Limiting strips 11 are symmetrically fixedly connected to the outer wall of the fixing rod 8. The limiting strips 11 are slidably connected to the limiting grooves 10. The top of the outer cavity 9 extends above the rotating cavity 3. It is fixedly connected to the lower surface of the shelf 4. A guide block 12 is fixedly connected to the outer wall of the outer cavity 9. A guide groove 13 is opened inside the rotating cavity 3. The guide block 12 is slidably connected to the inside of the guide groove 13. The bottom end of the output end of the motor 7 passes through to the bottom of the rotating cavity 3 and is fixedly connected to the rotating cylinder 14. The rotating cylinder 14 is slidably connected to the outer wall of the rotating cavity 3. A horizontal cavity 15 is fixedly connected to the right side of the lower surface of the box body 1. A slide plate 16 is slidably connected inside the horizontal cavity 15. An extension rod 17 is fixedly connected to the left end of the slide plate 16. The left end of the extension rod 17 passes through to the left end of the horizontal cavity 15 and is fixedly connected to the deceleration arc ring 18. A slide rod 19 is symmetrically rotatably connected to the inner wall of the deceleration arc ring 18.

[0027] When the standard light source observation box is in operation, the item to be compared in color is first placed on the shelf 4. Then, according to the comparison requirements, the illumination angle and type of the light source are adjusted to ensure that the light source can evenly cover the surface of the item. The motor 7 is started, and the output end of the motor 7 drives the fixed rod 8 to rotate. Because the limiting strip 11 on the outer wall of the fixed rod 8 is slidably connected to the limiting groove 10 on the inner wall of the outer cavity 9, the fixed rod 8 will drive the outer cavity 9 to rotate synchronously. The outer cavity 9 then drives the shelf 4 fixed at the top to rotate, so that the item rotates at a uniform speed with the shelf 4, making it convenient to observe the color of the item from different angles. After the motor 7 is started, when the fixed rod 8 rotates, the limiting strip 11 slides along the spiral groove, causing the outer cavity 9 to both rotate synchronously with the fixed rod 8 to maintain its original rotation function and move up and down along the axis of the fixed rod 8. The top of the outer cavity 9 is fixed to the shelf 4, thereby driving the shelf 4 and the item to achieve synchronous up and down movement and rotation. At the same time, the guide block 12 on the outer side of the outer cavity 9 slides along the guide groove 13 in the rotating cavity 3 to ensure stable movement.

[0028] In this embodiment, the outer side wall of the transverse cavity 15 is symmetrically provided with transverse sliding grooves 20, the outer side wall of the slide plate 16 is symmetrically fixedly connected with U-shaped plates 21, the U-shaped plates 21 are slidably connected with the outer side plate of the transverse cavity 15, the left end of the U-shaped plates 21 is fixedly connected with an electric telescopic rod 22, the electric telescopic rod 22 is fixedly connected with the lower surface of the transverse cavity 15, the outer side wall of the lamp holder cavity 6 is symmetrically provided with lamp holder grooves 23, and a standard light source lamp 24 is fixedly connected inside each lamp holder groove 23.

[0029] When it is necessary to control the rotation speed of the rotating drum 14, the electric telescopic rod 22 is activated. Its telescopic end pushes the U-shaped plate 21 to slide along the outer wall of the transverse cavity 15. Because the U-shaped plate 21 is fixedly connected to the slide plate 16, it will drive the slide plate 16 to move synchronously inside the transverse cavity 15. At the same time, the U-shaped plate 21 slides along the transverse sliding groove 20 on the outer side of the transverse cavity 15 to ensure stable movement trajectory. The slide plate 16 drives the extension rod 17 to push the deceleration arc ring 18 closer to the rotating drum 14. The friction between the slide rod 19 and the rotating drum 14 achieves deceleration, replacing manual pushing and improving operation accuracy. In the light source adjustment stage, different types of standard light sources 24 are fixed in the light slot 23 on the outer wall of the light cavity 6. The corresponding light source can be selected and turned on according to the comparison requirements.

[0030] In this embodiment, a small gear 25 is rotatably connected to the right side of the outer wall of the box 1, and a long rod 26 is fixedly connected to the left side of the small gear 25. The long rod 26 is fixedly connected to the lamp cavity 6. A large gear 27 is rotatably connected to the right side of the box 1. The large gear 27 meshes with the small gear 25. A locking slot 31 is opened on the outer wall of the large gear 27. A positioning slot 32 is symmetrically opened on the right side of the box 1, located to the left of the large gear 27. A rotating plate 28 is fixedly connected to the outer wall of the large gear 27. The front surface of the rotating plate 28 is fixedly connected to... A cartridge cavity 29 is connected, and a locking rod 30 is slidably connected inside the cartridge cavity 29. The locking rod 30 passes through the locking port 31 and engages with the positioning port 32. A central rod 33 is fixedly connected to the upper surface of the locking rod 30. The top end of the central rod 33 extends to the outer wall of the cartridge cavity 29. A spring coil 34 is wound around the outer wall of the central rod 33 inside the cartridge cavity 29. An opening 35 is opened on the front surface of the box body 1. An upper slot 36 is opened on the upper surface of the box body 1. A dustproof glass 37 is slidably connected inside the upper slot 36.

[0031] To adjust the light source angle, rotate the large gear 27 on the right side of the box 1. This gear meshes with the small gear 25, causing the small gear 25 to rotate. The long rod 26 on the left side of the small gear 25 rotates accordingly, which in turn rotates the lamp holder 6 within the rotating slot 5. This precisely adjusts the illumination angle of the standard light source 24, ensuring even light coverage of the items on the shelf 4. To adjust the angle of the standard light source 24, first pull the center rod 33 upwards, causing the locking rod 30 to slide upwards within the spring cavity 29, compressing the spring ring 34 and disengaging the locking rod 30 from the positioning port 32. Rotating the rotating plate 28 rotates the large gear 27, adjusting the angle of the lamp holder 6 through the meshing small gear 25 and long rod 26 until the angle of the standard light source 24 is appropriate. Release the center rod 33, and the spring coil 34 resets, pushing the locking rod 30 down to pass through the locking port 31 and engage with the corresponding positioning port 32, thus locking the large gear 27 and fixing the light source angle. For dust protection, during daily use, slide the dustproof glass 37 along the upper slot 36 into the box 1, covering the opening 35 to prevent dust from entering the box 1 and contaminating the shelf 4 and the standard light source 24. When placing or removing comparison items, slide the dustproof glass 37 upwards to open the opening 35. After operation, reset the dustproof glass 37 to ensure the cleanliness of the observation box and maintain color comparison accuracy.

[0032] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
