Abstract
Description
Technical Field
[0001] This application belongs to the field of light-blocking plate technology, and more specifically, relates to a light-blocking plate structure that is easy to slide. Background Technology
[0002] Outdoor LED displays are widely used in various public places. They are usually formed by splicing together several display screens. However, some displays are transparent screens, which transmit light. When the light transmission function is not needed, a mechanism is required to block the light. Existing technology uses light-blocking plates for blocking, but subsequent removal is inconvenient. Moreover, the light-blocking plates are fixed and cannot be adjusted as needed. Even if the light-blocking plates can slide, the friction of the plates is high and difficult to control. Utility Model Content
[0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this application is to provide a light-blocking plate structure that is easy to slide, with low friction between the plates, saving time and effort, and improving adjustment efficiency.
[0004] The technical means adopted in this application to solve the above-mentioned technical problems are:
[0005] This application provides a light-blocking plate structure that is easy to slide, comprising:
[0006] The first baffle has a plurality of spaced-apart first light-transmitting slits, and one side wall of the first baffle has an outwardly convex arc structure.
[0007] The second baffle is slidably disposed on the first baffle and abuts against the arc-shaped structure. The second baffle is provided with a plurality of mutually spaced second light-transmitting slits.
[0008] Preferably, the side wall of the first baffle is provided with an arc-shaped protrusion, and the second baffle abuts against the arc-shaped protrusion.
[0009] Preferably, the first baffle is provided with a limiting block, the second baffle is provided with a limiting groove, and the limiting block is inserted into the limiting groove.
[0010] Preferably, the sidewall of the second baffle is provided with an inwardly recessed groove.
[0011] Preferably, the groove is arranged along the long axis of the second light-transmitting slit.
[0012] Preferably, the arc-shaped protrusions are provided in multiple ways.
[0013] Compared with the prior art, the convenient sliding light-blocking plate structure of this application is provided with a first baffle and a second baffle. The first baffle has an arc-shaped structure, and the second baffle abuts against the arc-shaped structure. In this way, when the second baffle slides relative to the first baffle, the friction between the first baffle and the second baffle can be reduced. Furthermore, the first baffle has a first light-transmitting slit, and the second baffle has a second light-transmitting slit. When the first light-transmitting slit and the second light-transmitting slit are misaligned, the first baffle will block the second light-transmitting slit, and the second baffle will block the first light-transmitting slit. This achieves light blocking in a convenient and quick manner, and the relative position of the first baffle and the second baffle can be adjusted to adjust the degree of light blocking.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0021] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. Similar reference numerals and letters denote similar items in the following figures; therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0022] like Figures 1-3 As shown, this embodiment provides a convenient sliding light-blocking plate structure, including a first baffle 1 and a second baffle 2. The first baffle 1 is provided with a plurality of mutually spaced first light-transmitting slits 1a, and one side wall of the first baffle 1 is an outwardly convex arc surface structure 1b. The second baffle 2 is slidably disposed on the first baffle 1, and the second baffle 2 abuts against the arc surface structure 1b. The second baffle 2 is provided with a plurality of mutually spaced second light-transmitting slits 2a.
[0023] In some preferred embodiments of this utility model, the side wall of the first baffle 1 is provided with an arc-shaped protrusion 1c, and the second baffle 2 abuts against the arc-shaped protrusion 1c. In this way, the arc-shaped protrusion 1c can abut against the second baffle 2, so that there is a gap between the first baffle 1 and the second baffle 2, reducing sliding friction.
[0024] In some preferred embodiments of this utility model, the first baffle 1 is provided with a limiting block, and the second baffle 2 is provided with a limiting groove, with the limiting block inserted into the limiting groove. Thus, the limiting groove and the limiting block cooperate to limit the sliding of the second baffle 2, preventing excessive sliding.
[0025] In some preferred embodiments of this invention, the side wall of the second baffle 2 is provided with an inwardly recessed groove. Thus, the groove in the baffle reduces the overall weight of the baffle.
[0026] In some preferred embodiments of this invention, the groove is arranged along the long axis of the second light-transmitting slit 2a. This allows for a sufficiently large groove area, minimizing the weight of the baffle.
[0027] In some preferred embodiments of this invention, multiple arc-shaped protrusions 1c are provided. Thus, multiple arc-shaped protrusions 1c can ensure uniform force distribution and significantly reduce friction.
[0028] Compared with the prior art, the convenient sliding light-blocking plate structure of this application is provided with a first baffle 1 and a second baffle 2. An arc-shaped structure 1b is provided on the first baffle 1, and the second baffle 2 abuts against the arc-shaped structure 1b. In this way, when the second baffle 2 slides relative to the first baffle 1, the friction between the first baffle 1 and the second baffle 2 can be reduced. Furthermore, the first baffle 1 is provided with a first light-transmitting slit 1a, and the second baffle 2 is provided with a second light-transmitting slit 2a. When the first light-transmitting slit 1a and the second light-transmitting slit 2a are misaligned, the first baffle 1 will block the second light-transmitting slit 2a, and the second baffle 2 will block the first light-transmitting slit 1a. This achieves light blocking in a convenient and quick manner, and the relative position of the first baffle 1 and the second baffle 2 can be adjusted to adjust the degree of light blocking.
[0029] The above description is merely a specific embodiment of this application and is not intended to limit the scope of protection of this application.
