Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceiling access panel technology, and more specifically to a pre-embedded downward access panel structure. Background Technology
[0002] Ceilings are commonly used to install appliances such as chandeliers, ceiling fans, and air conditioners. To facilitate maintenance and repair of these appliances, inspection ports are usually provided in the ceiling. Existing inspection ports generally consist of a base plate and a cover plate. The base plate has a movable opening, and the cover plate fits into the movable opening. The edges of the movable opening are made of metal such as aluminum alloy. When in use, the cover plate is opened to access the inspection port for equipment maintenance. When not in use, the cover plate is closed to seal the movable opening.
[0003] The existing structure of the access panel is as follows: Chinese Patent: A Structure for Access Panel on Building Ceiling, Authorization Announcement No.: CN218479388U. This patent document discloses the specific structure and usage of the existing ceiling access panel. As can be seen from the above-disclosed patent content, the access panel can be slidably covered by a drive cover plate to realize the opening and sealing of the access panel, which is relatively convenient and simple to operate.
[0004] The existing access panels still have the following drawbacks when in use:
[0005] Disadvantage 1: The access panel is installed on the ceiling, and there is a certain difference in appearance between the access panel and the ceiling. The access panel lacks concealment and affects the aesthetics of the ceiling.
[0006] Disadvantage 2: The structure of the inspection port and cover is relatively delicate, and the installation and use are relatively precise, which can easily lead to inconvenience in use or replacement. Utility Model Content
[0007] The present invention discloses a pre-embedded bottom-opening maintenance port structure, the main purpose of which is to overcome the above-mentioned deficiencies and shortcomings of the existing technology.
[0008] The technical solution adopted in this utility model is as follows:
[0009] A pre-embedded bottom-opening maintenance port structure includes a base plate, a maintenance cover plate, and a rotating male-female fastener. The base plate has an opening, and the maintenance cover plate is detachably and movably installed at the opening via the rotating male-female fastener. The rotating male-female fastener includes a female fastener and a male fastener. The female fastener is fixedly installed on the base plate, and the female fastener is fixedly installed on the maintenance cover plate. The female fastener and the male fastener cooperate to rotate and lock in place. The base plate is also surrounded by mounting strips, and the inner sidewall of the mounting strips is fixedly connected to the base plate via fixing buckles.
[0010] Furthermore, a locking groove is provided on one side of the female buckle, and the male buckle can be rotatably locked into the locking groove. Fixed mounting holes are drilled on both the female buckle and the male buckle, and fixing screws can be inserted through the fixed mounting holes for fixing.
[0011] Furthermore, the female buckle has a "Z" shaped structure.
[0012] Furthermore, the female buckle has four fixing holes arranged at the four corners, and the male buckle has two fixing holes arranged symmetrically from left to right.
[0013] Furthermore, the number of the rotating snap fasteners is four.
[0014] Furthermore, the fixing buckle has an "L" shaped structure.
[0015] Furthermore, the mounting strip is arranged in a square frame structure, and there are two fixing buckles on each side of the square.
[0016] As can be seen from the above description and explanation of this utility model, compared with the prior art, the advantages of this utility model are as follows:
[0017] Advantage 1: This utility model, by setting a base plate, an inspection cover plate, and a rotating male and female fastener, can achieve a concealed rotating cover plate, avoiding any difference in effect between the base plate and the inspection cover plate, and improving the aesthetics of the ceiling.
[0018] Advantage 2: By setting a rotating male and female buckle, this utility model is not only simpler and more practical in structure, but also allows for stable installation of the inspection cover, which can be hidden at the opening of the base plate, making it convenient and quick to use.

[0023] Among them, the base plate 1, opening 11, mounting strip 12, fixing buckle 13, inspection cover 2, rotating male and female buckle 3, male buckle 31, female buckle 32, locking groove 321, and fixing mounting hole 322. Detailed Implementation
[0024] The specific embodiments of this utility model will be further described and illustrated below with reference to the accompanying drawings.
[0025] like Figures 1 to 4 As shown, a pre-embedded access panel structure includes a base plate 1, an access cover plate 2, and four rotating male and female fasteners 3. The base plate 1 has an opening 11. The access cover plate 2 is detachably and movably installed at the opening 11 via the rotating male and female fasteners 3. Each rotating male and female fastener 3 includes a female fastener 31 and a female fastener 32. The female fastener 31 is fixedly installed on the base plate 1, and the female fastener 32 is fixedly installed on the access cover plate 2. The female fastener 32 and the female fastener 31 are engaged and rotated together for secure fixation. A locking slot 321 is provided on the left side of the female fastener 32, into which the female fastener 31 can be movably and rotated to engage. Fixing holes 322 are drilled on both the female fastener 32 and the female fastener 31, and fixing screws can be inserted through these fixing holes 322 for fixation. The female buckle 32 has a "Z" shaped structure and four fixing holes 322 arranged at the four corners. The male buckle 31 has two fixing holes 322 arranged symmetrically from left to right.
[0026] like Figures 1 to 4 As shown, the base plate 1 is also surrounded by mounting strips 12. The base plate 1 is detachably fixed to the ceiling by the mounting strips 12. The inner sidewall of the mounting strips 12 is fixedly connected to the base plate 1 by fixing buckles 13. The fixing buckles 13 are in the shape of an "L" and the mounting strips 12 form a square frame structure, with two fixing buckles 13 on each side of the square.
[0027] When using:
[0028] First, install the male buckles of the rotating male-female buckle 3 at the opening 11 of the base plate 1. Then, install the female buckle of the rotating male-female buckle 3 at the edge of the inspection cover 2. When the opening 11 needs to be covered, align the inspection cover 2 with the opening 11 so that the female buckle 32 and the male buckle 31 are aligned. Then, rotate the inspection cover 2 so that the male buckle 31 is engaged in the locking groove 321 on the female buckle 32, thus completing the rotational engagement of the male buckle 31 and the female buckle 32. At the same time, the inspection cover 2 is fixed to the opening 11 of the base plate 1 by the rotating male-female buckle 3, achieving a hidden fixation and making the base plate 1 and the inspection cover 2 have the same effect.
[0029] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial improvements made to this utility model using this concept should be considered as infringing on the protection scope of this utility model.
