Description

Technical Field

[0001] The utility model relates to the technical field of digital tubes, in particular to a curved digital tube. Background Art

[0002] A digital tube, also known as a glow tube, is an electronic device that can display numbers and other information. The glass tube includes an anode made of a metal mesh and multiple cathodes. Most digital tube cathodes are in the shape of numbers. The tube is filled with low-pressure gas, usually mostly neon with some mercury or argon. When one of the cathodes is charged, the digital tube will emit colored light, depending on the gas in the tube, usually orange or green.

[0003] A Chinese patent discloses a curved digital tube that is easy to install (authorization announcement number CN 212809656U). The patented technology can adjust the distance between the pins of the curved digital tube, making it easy to install the curved digital tube. However, the structure of the existing curved digital tube is too simple, and its two ends are directly fixed inside the lamp housing, which is a rigid connection and has weak anti-vibration and buffering properties, making the curved digital tube easily affected by resonance, causing damage to internal parts, affecting working stability, and shortening the service life.

[0004] Therefore, those skilled in the art provide a curved digital tube to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a curved digital tube, including a curved digital tube, an FPC board and a chip;

[0006] The upper and lower ends of the curved digital tube are provided with a connecting block 1, the outer side of the connecting block 1 is provided with a shock-absorbing damper, the upper end of the shock-absorbing damper is provided with a top plate, the outer side of the top plate is provided with a connecting side plate, the inner side of the connecting side plate close to the curved digital tube is provided with a connecting shaft, the upper sliding of the connecting shaft is provided with two connecting rings, a spring is provided between the connecting shaft and the connecting block 2, a linkage rod is provided on the left side of the connecting ring, a connecting ring is fixed on the left side of the linkage rod, a fixed block is provided on the left side of the connecting ring, and the fixed block is fixed on the left side of the curved digital tube, through the setting of the connecting block 2, the connecting shaft, The connecting ring, spring, linkage rod, connecting ring and fixed block are arranged, and the shock-absorbing damping is arranged to perform shock-absorbing operation on the curved digital tube up and down. After the fixed block is vibrated, the linkage rod pushes the spring arranged on the right side to slide on the connecting shaft, so that the curved digital tube can be shock-absorbing. This solves the problem that the existing device structure is too simple, and its two ends are directly fixedly installed inside the lamp housing, which is a rigid connection and has weak shock-absorbing performance, resulting in the curved digital tube being easily affected by resonance, causing damage to internal parts, affecting working stability, and shortening service life.

[0007] Preferably: the FPC board comprises a flexible substrate and a flexible additional circuit board, the chip is packaged on the flexible additional circuit board, and the housing is provided with light emitting channels corresponding to the light emitting positions of each chip.

[0008] Preferably: fluorescent glue is provided in the light-emitting channel. The curved digital tube sets the PCB board as an FPC board so that the angle of the chip can be bent and adjusted after packaging, thereby improving the light-emitting angle and viewing angle of the curved digital tube. The curved digital tube adopts a REF with an arc-shaped outer side surface and adopts an FPC board adhesive to increase the light-emitting angle of the digital tube. At the same time, since the curvature of the FPC board is the same as the curvature of the outer side surface of the REP, the distance from the light-emitting chip to the outer side surface of the shell is equal, so that each chip emits light evenly from the REF, thereby improving the consistency of the curved digital tube. The number of the top plates is two.

[0009] Technical effects and advantages of the utility model:

[0010] 1. The utility model arranges a connecting block 2, a connecting shaft, a connecting ring, a spring, a linkage rod, a connecting ring and a fixed block, and cooperates with the arranged shock-absorbing damping to perform a shock-absorbing operation on the curved digital tube up and down. After the fixed block receives the vibration, the linkage rod pushes the spring arranged on the right side to slide on the connecting shaft, so that the curved digital tube can be shock-absorbing. The shock-absorbing effect is good and the practicality is good, which is convenient for extending the service life of the curved digital tube, has high shock-absorbing performance, will not be affected by resonance, will not cause damage to internal parts, and will not affect working stability. The problem that the existing device structure is too simple, its two ends are directly fixedly installed inside the lamp housing, which is a rigid connection and has weak shock-absorbing performance, resulting in the curved digital tube being easily affected by resonance, causing damage to internal parts, affecting working stability, and having a short service life is solved.

[0011] 2. This curved digital tube adopts a curved REF on the outer side and uses an FPC board to increase the light-emitting angle of the digital tube. At the same time, since the curvature of the FPC board is the same as the curvature of the outer side of the REP, the distance from the light-emitting chip to the outer side of the shell is equal, so that the light from each chip to the REF is uniform, which improves the consistency of the curved digital tube.

[0021] Example 1

[0022] See also Figures 1 to 7In this embodiment, a curved digital tube is provided, including a curved digital tube 1, an FPC board 2 and a chip 5. The FPC board 2 includes a soft substrate and a soft additional circuit board. The chip 5 is packaged on the soft additional circuit board. A light outlet channel 4 corresponding to the light emitting position of each chip 5 is arranged on the shell 3. Fluorescent glue is arranged in the light outlet channel 4. The curved digital tube 1 sets the PCB board as the FPC board 2 so that the angle of the chip 5 can be bent and adjusted after packaging, thereby improving the light emitting angle and viewing angle of the curved digital tube 1. The curved digital tube 1 adopts a curved REF on the outer side and adopts the FPC board 2 to increase the light emitting angle of the digital tube. At the same time, since the curvature of the FPC board 2 is the same as the curvature of the outer side of the REP, the distance from the light emitting chip 5 to the outer side of the shell 3 is equal, so that the light from each chip 5 to the REF is uniform, thereby improving the consistency of the curved digital tube 1;

[0023] The upper and lower ends of the curved digital tube 1 are provided with a connecting block 6, the outer side of the connecting block 6 is provided with a shock absorbing damper 7, the upper end of the shock absorbing damper 7 is provided with a top plate 8, the number of the top plates 8 is two, the outer side of the top plate 8 is provided with a connecting side plate 9, the inner side of the connecting side plate 9 close to the curved digital tube 1 is provided with a connecting shaft 11, the upper sliding of the connecting shaft 11 is provided with two connecting rings 12, a spring 13 is provided between the connecting shaft 11 and the connecting block 2 10, a linkage rod 14 is provided on the left side of the connecting ring 12, a connecting ring 15 is fixed on the left side of the linkage rod 14, a fixing block 16 is provided on the left side of the connecting ring 15, and the left side of the fixing block 16 is fixed on the curved digital tube 1. When in use, when the curved digital tube 1 is hit, the shock absorbing damper 7 at the upper and lower ends is firstly used to perform a shock absorbing operation on the curved digital tube 1 up and down, which well avoids the problem of the curved digital tube 1 being hit up and down, and is convenient for vertical adjustment of the curved digital tube 1. The shock-absorbing operation in the direction prolongs the service life of the curved digital tube 1. Secondly, when the fixing block 16 receives the vibration, the force is first given to the fixing block 16, and then the connecting ring 15 and the linkage rod 16 feel the force. At this time, the linkage rod 14 pushes the two springs 13 set on the right side to slide on the connecting shaft 11 and pushes to the position of the connecting block 10. At this time, the spring 13 is used to perform a shock-absorbing operation on the force, so that the curved digital tube 1 can be subjected to a shock-absorbing operation. The shock-absorbing effect is good and the practicality is good, which is convenient for prolonging the service life of the curved digital tube 1. In addition, the utility model can solve the problem that the existing device adopts a combination of multiple PCB boards, the manufacturing process is cumbersome, the production efficiency is low, and the light uniformity still cannot reach a good level, and the slightly larger arc surface still cannot achieve a good display effect.

[0024] The utility model arranges a connecting block 10, a connecting shaft 11, a connecting ring 12, a spring 13, a linkage rod 14, a connecting ring 15 and a fixed block 16, and cooperates with the arranged shock-absorbing damper 7 to perform a shock-absorbing operation on the curved digital tube 1 up and down. After the fixed block 16 receives the vibration, the linkage rod 14 pushes the spring 13 arranged on the right side to slide on the connecting shaft 11, so that the shock-absorbing operation can be performed on the curved digital tube 1, thereby solving the problem that the existing device structure is too simple, the two ends of which are directly fixedly installed inside the lamp housing, which is a rigid connection and has weak anti-seismic buffering performance, resulting in the curved digital tube being easily affected by resonance, causing damage to internal parts, affecting working stability, and shortening the service life.
