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 can be precisely adjusted. 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 of these 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 this purpose, 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, making them difficult to control and resulting in generally low precision. 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 can be precisely adjusted, with low friction between the plates, saving time and effort, and improving adjustment accuracy.
[0004] The technical means adopted in this application to solve the above-mentioned technical problems are:
[0005] This application provides a precisely adjustable light-blocking plate structure, comprising:
[0006] The first baffle has a plurality of spaced-apart first light-transmitting slits, and one side wall of the first baffle has outwardly protruding guide ribs.
[0007] The second baffle is slidably disposed on the first baffle and is provided with a guide channel. The guide rib is slidably inserted into the guide channel and is provided with a plurality of mutually spaced second light-transmitting slits.
[0008] Preferably, the first baffle is provided with a guide block, the second baffle is provided with a guide hole, and the guide block is inserted into the guide hole.
[0009] Preferably, multiple guide holes and guide blocks are provided, and the guide blocks are inserted into the guide holes one by one.
[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 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.
[0013] Compared with the prior art, the precisely adjustable light-blocking plate structure of this application is provided with a first baffle and a second baffle. The first baffle is provided with a guide rib, and the second baffle is provided with a guide channel. The guide rib is inserted into the guide channel. When the second baffle slides relative to the first baffle, the guide rib will slide in the guide channel, thereby guiding the second baffle and improving the adjustment accuracy. Furthermore, the first baffle is provided with a first light-transmitting slit, and the second baffle is provided with 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.

[0019] 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.
[0020] 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.
[0021] like Figures 1-2 As shown, this embodiment provides a precisely adjustable 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 has an outwardly protruding guide rib 1b. The second baffle 2 is slidably disposed on the first baffle 1, and the second baffle 2 is provided with a guide channel 2b, the guide rib 1b is slidably inserted into the guide channel 2b, and the second baffle 2 is provided with a plurality of mutually spaced second light-transmitting slits 2a.
[0022] In some preferred embodiments of this utility model, the first baffle is provided with a guide block, and the second baffle is provided with a guide hole, with the guide block inserted into the guide hole. Thus, the guide block 1c, in conjunction with the guide hole 2c, can further ensure the accuracy of guidance and adjustment.
[0023] In some preferred embodiments of this utility model, multiple guide holes 2c and guide blocks 1c are provided, and each guide block 1c is inserted into a guide hole 2c in a one-to-one correspondence. Thus, by using multiple guide blocks 1c and guide holes 2c, the uniformity of force during the guiding process can be ensured.
[0024] In some preferred embodiments of this invention, the side wall of the second baffle 2 is provided with an inwardly recessed groove. Thus, by providing the groove, the weight of the second baffle 2 can be reduced.
[0025] In some preferred embodiments of this invention, the groove is arranged along the long axis of the second light-transmitting slit 2a. This design along the long axis of the second light-transmitting slit 2a minimizes the weight of the second baffle 2 and facilitates sliding.
[0026] In some preferred embodiments of this invention, 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 can restrict the movement of the limiting block and prevent excessive sliding.
[0027] Compared with the prior art, the precisely adjustable light-blocking plate structure of this application is provided with a first baffle 1 and a second baffle 2. A guide rib 1b is provided on the first baffle 1, and a guide channel 2b is provided on the second baffle 2. The guide rib 1b is inserted into the guide channel 2b. When the second baffle 2 slides relative to the first baffle 1, the guide rib will slide in the guide channel 2b, thereby guiding the second baffle 2 and improving the adjustment accuracy. 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.
