Description

Technical Field

[0001] The invention relates to the technical field of reflective covers, in particular to a digital tube reflective cover. Background Art

[0002] Digital tube is an electronic component widely used in digital display, often used to display digital or partial letter information. The most common type is the seven-segment digital tube, each of which consists of 7 LEDs (light-emitting diodes) or LCDs (liquid crystal display), and displays the numbers 0-9 and partial letters by lighting different segments. Digital tubes are widely used in various electronic devices, such as electronic clocks, counters, instruments, home appliance control panels, etc.

[0003] The reflective cover in the digital tube is a protective component covering the display area, usually made of transparent or translucent materials, designed to enhance the display effect of the digital tube. Its main function is to improve the brightness and visibility of the digital tube by reflecting light, especially in a dimly lit environment, which can significantly improve the clarity of the displayed content. In addition, the reflective cover also plays a role in dust and moisture resistance, protecting the internal circuit and extending the service life of the digital tube. In some designs, the reflective cover may also integrate a heat dissipation function to help the digital tube maintain a stable operating temperature when working for a long time.

[0004] However, when a traditional digital tube has a circuit board failure, such as a dead light or flickering light, it is usually impossible to replace the light source alone. Since the circuit board module of the digital tube adopts an integrated design and packaging method, a failure often means that the entire module needs to be replaced, rather than a single LED or circuit component. This maintenance method involves replacing the entire module, which in turn increases costs in terms of labor, equipment, and downtime. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a digital tube reflective cover to solve the circuit board failures in the digital tube, such as dead lights and flickering. It is often impossible to replace the light source alone. Due to the integrated design of the circuit board display module and the component packaging method, the problem needs to be solved by replacing the entire module, which involves the cost of labor, equipment and downtime.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a digital tube reflective cover, comprising a cover body, the top of the cover body is rotatably connected to a flip cover, a limit mechanism is arranged inside the cover body, and two sets of mounting mechanisms are fixedly connected to the outside of the cover body; The limiting mechanism includes a sliding groove, which is arranged inside the cover body, a sliding block is slidably connected inside the sliding groove, a spring 1 and a limiting rod are fixedly connected outside the sliding block, an end of the spring 1 away from the sliding block is fixedly connected inside the sliding groove, the limiting rod is slidably connected inside the cover body, and a sliding plate is fixedly connected to the top of the sliding block.

[0022] Please refer to the attached Figure 1 -Attached Figure 8 The embodiment of the present invention provides a digital tube reflective cover, comprising a cover body 1, a flip cover 2 is rotatably connected to the top of the cover body 1, a limiting mechanism 5 is arranged inside the cover body 1, two sets of mounting mechanisms 6 are fixedly connected to the outside of the cover body 1, and the top of the digital tube reflective cover is connected to the cover body 1 through the flip cover 2. When the user needs to replace the lamp beads 13 on the damaged circuit board 12 or the diffusion plate 7 in the flip cover 2, the flip cover 2 can be easily disassembled by operating the limiting mechanism 5; Please refer to the attached Figure 1 -Attached Figure 4 The limiting mechanism 5 includes a sliding groove 501, which is arranged inside the cover body 1. A sliding block 503 is slidably connected inside the sliding groove 501. A spring 1 502 and a limiting rod 505 are fixedly connected to the outside of the sliding block 503. The end of the spring 1 502 away from the sliding block 503 is fixedly connected to the inside of the sliding groove 501. The limiting rod 505 is slidably connected to the inside of the cover body 1. A sliding plate 504 is fixedly connected to the top of the sliding block 503. The limiting mechanism 5 includes a sliding groove 501 and a sliding block 503 inside. The sliding block 503 is connected to the sliding groove 501 in the cover body 1 through the spring 1 502 and the limiting rod 505. When the flip cover 2 needs to be disassembled, the sliding plate 504 drives the sliding block 503 to move, and the movement of the sliding block 503 causes the limiting rod 505 to disengage from the limiting groove 506, thereby releasing the restriction of the flip cover 2. The user only needs to pull the flip cover pulling plate 15 to open the flip cover 2, thereby performing the disassembly and replacement operation.

[0023] Please refer to the attached Figure 1 -Attached Figure 6 The mounting mechanism 6 includes two mounting blocks 601, which are fixedly connected to the outside of the cover body 1. The mounting block 601 is provided with a mounting groove 602 inside. Two groups of clamping blocks 606 are slidably connected inside the mounting groove 602. The outside of the clamping block 606 is fixedly connected with a second spring 603 and a pull rod 604. The end of the second spring 603 away from the clamping block 606 is fixedly connected to the inside of the mounting groove 602. The end of the pull rod 604 away from the clamping block 606 is fixedly connected with a pull block 605. The outside of the pull rod 604 is slidably connected to the inside of the mounting block 601. The bottom of the mounting block 601 is provided with a through groove 607. The inside of the mounting block 601 is provided with a clamping assembly. Two groups of mounting mechanisms 6 are provided outside the reflective cover, including the mounting block 601, the mounting groove 602, the clamping block 606, the second spring 603 and the pull rod 604. The mounting mechanism 6 and the clamping assembly work together to make the installation and removal of the reflective cover easier.

[0024] Please refer to the attached Figure 5 -Attached Figure 6 The clamping assembly includes a clamping block 608, which is arranged inside the mounting block 601. The outside of the clamping block 608 abuts against the inner side 606 of the clamping block. The bottom of the clamping block 608 is fixedly connected with a fixing block 609. When the reflective cover needs to be removed, the user pulls the pulling block 605 in the mounting mechanism 6 to drive the pulling rod 604 to move. The movement of the pulling rod 604 causes the clamping block 606 to move outward, thereby releasing the clamping state between the clamping block 608 and the clamping block 606. At this time, the clamping block 608 is unlocked, and the user can easily remove the reflective cover.

[0025] Please refer to the attached Figure 1 -Attached Figure 7 The cover 1 has a plurality of connection columns 11 fixedly connected inside, and the plurality of connection columns 11 are connected by a plurality of reinforcement plates 14, and the reinforcement plates 14 are connected to the inside of the cover 1 by a plurality of reinforcement ribs 10. Two groups of anti-deformation pre-arches 9 are provided at the bottom of the cover 1, and a plurality of connection columns 11 are provided inside the cover 1. These connection columns 11 provide structural support together with the reinforcement plates 14 and the reinforcement ribs 10 to enhance the bearing capacity of the reflective cover. A buffer cavity is formed between two adjacent reinforcement ribs 10, and the cross-sections of these buffer cavities are triangular and arranged in opposite directions. This design effectively improves the compressive strength and durability of the cover 1, can withstand various external forces and impacts, and ensures the stability of the reflective cover during long-term use. The anti-deformation pre-arch 9 structure is designed at the bottom of the cover 1, which plays an effective role in preventing deformation during use, ensuring that the cover 1 can maintain its original shape when subjected to external forces, and enhancing the stability and durability of the device.

[0026] Please refer to the attached Figure 1The outside of the cover body 1 is fixedly connected with two sets of anti-skid patterns 8. The anti-skid patterns 8 on the outside of the cover body 1 enhance the user's grip during operation and prevent sliding or slipping.

[0027] The outside of the connecting column 11 is fixedly connected with the digital display block 3, the inside of the digital display block 3 is provided with a reflection groove 4, the bottom of the digital display block 3 is provided with a plurality of light source grooves 16, the inside of the light source groove 16 is provided with a plurality of lamp beads 13, the bottom of the lamp beads 13 is fixedly connected with the circuit board 12, the outside of the circuit board 12 is in contact with the outside of the connecting column 11, and the digital display block 3 inside the digital tube reflection cover provides a clear digital display effect through the reflection groove 4 and the plurality of light source grooves 16, combined with the lamp beads 13, the circuit board 12 and the connecting column 11. The lamp beads 13 in the light source groove 16 are in contact with the connecting column 11 outside the cover body 1 through the circuit board 12 to ensure the normal operation of the lamp beads 13.

[0028] Please see attached Figure 1 A plurality of diffusion plates 7 are arranged on the top of the flip cover 2 , a pulling plate 15 is fixedly connected to the top of the flip cover 2 , the pulling plate 15 is used to manually pull the flip cover 2 , and the diffusion plates 7 are used to diffuse the light of the lamp beads 13 .

[0029] Please see attached Figure 6 The through slot 607 is connected to the mounting slot 602 , and the clamping block 608 enters the interior of the mounting slot 602 through the through slot 607 .

[0030] Please see attached Figure 3 -Attached Figure 4 The end of the limiting rod 505 away from the sliding block 503 is arranged inside the limiting groove 506, and the limiting groove 506 is arranged inside the flip cover 2. This design can limit the movement path of the sliding block 503 to prevent it from excessive sliding or deviating from the predetermined track, thereby ensuring the stability and precise operation of the device.

[0031] Working principle: During the disassembly and installation process of the digital reflective cover, the design of the device fully considers the convenience and efficiency of disassembly and installation. Through the clever cooperation of the installation mechanism 6 and the locking assembly, the user can easily complete the disassembly operation. Specifically, the user only needs to pull the pulling block 605 in the installation mechanism 6, and the pulling block 605 drives the pulling rod 604 to move, and then the pulling rod 604 drives the clamping block 606 to move in the opposite direction. In this way, the two sets of clamping blocks 606 will unlock the originally locked card block 608, so that the reflective cover can be smoothly removed from the digital tube. This design greatly simplifies the disassembly process of the reflective cover, makes maintenance work more convenient, and saves time and manpower.

[0032] When the digital display device fails, the coordinated design of the flip cover 2 and the limiting mechanism 5 further improves the convenience of the maintenance operation. The user can open the cover body 1 through the flip cover, and use the limiting mechanism 5 to easily replace the damaged lamp beads 13 on the circuit board 12 or the diffuser plate 7 in the flip cover 2. The design of the limiting mechanism 5 makes the disassembly of the flip cover 2 more efficient. When the lamp beads 13 or the diffuser plate 7 are abnormal, the user only needs to operate the sliding plate 504 to drive the sliding block 503 to move in the sliding groove 501. The movement of the sliding block 503 will further promote the displacement of the limiting rod 505, and finally make the limiting rod 505 disengage from the limiting groove 506, releasing the fixed state of the flip cover 2. At this time, the user can directly pull the pulling plate 15 of the flip cover 2, easily open the flip cover 2, and complete the maintenance and replacement operations. This mechanism not only improves the convenience of operation, but also reduces the difficulty of operation that may occur during the maintenance process.

[0033] In addition, in order to ensure the strength and durability of the digital reflective cover, a plurality of reinforcing ribs 10 and reinforcing plates 14 are arranged inside the cover body 1. A plurality of buffer cavities are formed between these reinforcing ribs 10 and reinforcing plates 14, and the cross-section of the buffer cavities is designed to be triangular. When the buffer cavities are adjacent, they are arranged in opposite directions. This design effectively enhances the bearing capacity and strength of the overall structure. Through reasonable mechanical design, the buffer cavities can evenly disperse the force under external pressure or impact, thereby significantly improving the pressure resistance and durability of the reflective cover, and ensuring its stability and reliability in long-term use.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
