Description

Technical Field

[0001] This utility model relates to the field of reflective covers, specifically a reflective cover structure. Background Technology

[0002] A reflective cover is a key component widely used in display devices (such as dashboards, electronic indicators, and industrial control panels). Its core function is to protect internal precision components such as digital tubes, while ensuring clear visibility of the displayed content through specific structural designs (such as reflective surfaces or transparent panels). Under complex operating conditions (such as mechanical vibration, temperature changes, and frequent disassembly and assembly), the reflective cover must possess high structural strength and stable connection performance to avoid deformation, loosening, or functional failure due to external impacts or long-term use.

[0003] Existing reflector covers have the following drawbacks: Traditional reflector covers often use a one-piece structure (such as direct injection molding of the cover plate), relying on screws or adhesive for fixation, leading to stress concentration and easy breakage. Furthermore, the cover plate is usually a simple flat design, making it difficult to distribute external loads, resulting in insufficient bending and compressive strength and low structural strength. Traditional reflector covers lack a supporting and fixing structure, making them prone to displacement or detachment during installation due to uneven stress. In addition, they lack a self-locking buckle structure, relying solely on friction or screws for fixation, which easily loosens under vibration, resulting in poor connection stability. Repeated manual adjustments are required during installation, and misalignment can lead to loose fits at the joint surfaces, widening gaps over long-term use and affecting stability. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a reflective cover structure that can effectively solve the technical problems of low strength and poor connection stability of existing reflective cover structures.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a reflective cover structure, including a cover plate and a digital tube. The cover plate has two fixing grooves on its side, both of which extend along the height direction of the cover plate and are symmetrically arranged between each other. A support frame is provided at the bottom of the cover plate, and the support frame is provided with several support plates. A hollow support rod is provided at the bottom of the cover plate. The support rod and the support frame form an integrated structure through the support plates. Several U-shaped upright plates are provided at the bottom of the cover plate. The openings of adjacent U-shaped upright plates gradually decrease from one side of the support frame outward. A locking block is provided on both sides of the U-shaped upright plate. One end of the cover plate extends outward to form a limiting part. The limiting part has a locking groove with an outward opening. The locking groove is provided with a locking post with a hollow structure.

[0006] Furthermore, the surface of the cover plate is recessed inward to form a limiting groove, and the digital tube is installed inside the limiting groove.

[0007] Furthermore, a transparent plate is attached to the surface of the cover plate by screws.

[0008] Furthermore, one end of the cover plate extends outward to form two fixing parts, which are symmetrically arranged, and the surface of the fixing parts is provided with screw holes.

[0009] Furthermore, one end of the cover plate extends outward to form two positioning parts, which are symmetrically arranged.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The reflective cover structure of this utility model has symmetrically arranged fixing grooves, which can ensure that it can be better snapped into the corresponding position during installation. The integrated support rod and support frame enhance the overall structural strength and reduce the risk of damage to the reflective cover. The U-shaped vertical plate opening is gradually set and the snap-fit ​​structure is formed by the snap-fit ​​block, which facilitates quick snap-fit ​​positioning. The cooperation of the limiting part, the slot and the snap-fit ​​post enables the reflective cover to achieve precise positioning, which greatly improves the reliability and stability of the connection.

[0015] 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.

[0016] The following is combined Figure 1 and Figure 2 A detailed description of a reflective cover structure according to this utility model is provided below:

[0017] A reflective cover structure includes a cover plate 1 and a digital tube 3. The cover plate 1 has two fixing grooves 4 on its side, both extending along the height direction of the cover plate 1 and symmetrically arranged. A support frame 7 is provided at the bottom of the cover plate 1, and the support frame 7 is provided with several support plates 8. A hollow support rod 9 is provided at the bottom of the cover plate 1. The support rod 9 forms an integrated structure with the support frame 7 through the support plates 8. Several U-shaped upright plates 10 are provided at the bottom of the cover plate 1. The openings of adjacent U-shaped upright plates 10 gradually decrease from one side of the support frame 7 outwards. A locking block 11 is provided on both sides of the U-shaped upright plate 10. One end of the cover plate 1 extends outwards to form a limiting part 13. The limiting part 13 has a locking groove with an outward opening, and the locking groove is provided with a hollow locking post 14.

[0018] The surface of the cover plate 1 is recessed inward to form a limiting groove. The digital tube 3 is installed inside the limiting groove. A transparent plate 2 is installed on the surface of the cover plate 1 by screws. One end of the cover plate 1 extends outward to form two fixing parts 5. The two fixing parts 5 are symmetrically arranged. The surface of the fixing part 5 is provided with screw holes 6. One end of the cover plate 1 extends outward to form two positioning parts 12. The two positioning parts 12 are symmetrically arranged.

[0019] The limiting groove allows the digital tube 3 to be embedded and installed, avoiding displacement or external impact, while ensuring the flatness of the display area. The transparent plate 2 improves visibility. The transparent plate 2 is fixed with screws, which can protect the internal digital tube 3 from dust and water, and facilitate disassembly and maintenance. The cooperation between the positioning part 12 and the fixing groove 4 can achieve precise alignment and installation, reduce manual adjustment errors, and improve assembly efficiency. The opening of the U-shaped upright plate 10 gradually decreases from the support frame 7. This stepped fixing can be achieved by snap-fit ​​connection between the buckle 11 and the U-shaped upright plate 10 to prevent it from falling off. The hollow support rod 9, support plate 8 and support frame 7 can keep the reflector cover strong against bending. Combined with the stress-distributing design of the U-shaped upright plate 10, the structural strength of the reflector cover is greatly improved. The hollow support rod 9 and the support frame 8 and support plate 7 are integrated to optimize load distribution and enhance impact resistance. The gradual opening design of the U-shaped upright plate 10, combined with the double-sided buckle 11, can achieve self-locking and fastening to prevent loosening caused by vibration.

[0020] In this embodiment, a reflective cover structure features symmetrically arranged fixing grooves 4, which ensure better insertion into the corresponding positions during installation. The integrated support rod 9 and support frame 7 enhance the overall structural strength and reduce the risk of damage to the reflective cover. The U-shaped upright plate 10 with its gradually changing opening and the locking block 11 form a snap-fit ​​structure, facilitating quick snap-fit ​​positioning. The cooperation of the limiting part 13, the locking groove, and the locking post 14 enables the reflective cover to achieve precise positioning, greatly improving the reliability and stability of the connection.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
