Description

Technical Field

[0001] This utility model relates to the technical field of pre-embedded square rounded corner inspection port tools, and in particular to pre-embedded square rounded corner inspection ports. Background Technology

[0002] In the field of modern building engineering, pre-embedded inspection ports are a key infrastructure component and are widely used in various buildings for daily inspection, maintenance and repair of pipes, lines and equipment inside the building. With the continuous advancement of building technology and people’s increasing requirements for building quality, more stringent standards have been put forward for the performance and design of pre-embedded inspection ports.

[0003] In the traditional inspection port construction process, due to the poor material and processing technology of the cover plate, the flatness of the traditional inspection port cover plate is poor, which often makes it difficult to directly apply primer. This results in complicated procedures and poor results, causing uneven gaps after installation, affecting the overall aesthetics and sealing effect. Therefore, this application designs a pre-embedded square rounded corner inspection port to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pre-embedded square rounded corner inspection port.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example: See Figure 1-4The pre-embedded square rounded corner access port of this utility model includes a frame 1. Four snap-fit ​​strips 3 are attached to the frame 1, which facilitates a firm connection between the various parts of the frame 1, improving the overall stability and durability of the frame 1 and preventing loosening or deformation during long-term use. A sliding groove 10 is provided on the inner wall of the frame 1, which allows it to better adapt to different installation spaces and conditions, improving the versatility of the access port. Adapter angles 4 abut against both sides of the snap-fit ​​strips 3, which facilitate flexible assembly and dimensional adjustments of the frame 1, while also strengthening the connection points and reducing the risk of breakage at the joints. A movable block is fixed to one side of corner 4, and the movable block is slidably connected in the sliding groove 10. A putty-embedded frame 9 is fixed to the bottom of the frame 1. The putty-embedded frame 9 facilitates the stable installation of the access panel. The decorative pattern 11 has a hollow structure, which is to allow the putty to pass through the frame and connect with the ceiling plasterboard when the frame is puttyed, so that the access panel is installed more firmly. An abutment block 7 is fixed to the inner ring of the frame 1. The abutment block 7 facilitates the stable placement of the access panel cover 2, and the rounded corner design extends the service life of the cover. The four corners of the abutment block 7 are rounded, and the access panel cover 2 is placed on the abutment block 7. The access panel cover 2 facilitates the effective closing and opening of the access panel.

[0019] In this utility model, the frame 1 is composed of four frame strips, which are fixedly connected by four corner joints 4. Four snap-fit ​​strips 3 are snapped onto the four frame strips, facilitating easy and convenient assembly of the frame 1. The top surface of the access cover 2 is provided with an operating groove 5, and the bottom surface of the access cover 2 is coated with primer 6. The access cover 2 is made of PVC wood-plastic composite board material. The primer 6 effectively prevents corrosion damage caused by moisture, oxidation, and other factors, ensuring long-term stable use of the cover. Multiple grooves are equidistantly spaced on the putty-embedded frame 9. The decorative pattern 11 consists of a five-pointed star through hole and a circular through hole on the inner side. Both the five-pointed star through hole and the circular through hole can improve the firmness of contact with the putty surface. Screws can also pass through the circular through hole to fix the putty pre-embedded frame 9. The front of the putty pre-embedded frame 9 is provided with a wear-resistant groove to facilitate putty adhesion. A reinforcing rib 8 is fixed to the outer wall of the transition corner 4. One end of the reinforcing rib 8 is fixed to the inner wall of the frame 1. The reinforcing rib 8 can greatly improve the strength of the connection part of the frame 1 and avoid the situation of breakage and deformation at the connection due to external force.

[0020] Working Principle: In the use of this utility model, firstly, the frame 1 is constructed. The frame 1 serves as the basic structure of the access panel and is composed of four snap-fit ​​strips 3 connected by four corner joints 4. The movable block on one side of the corner joint 4 slides into the sliding groove 10 on the inner wall of the frame 1. This connection method not only constructs the square frame 1 but also gives the frame 1 the ability to flexibly adjust its size. During installation, if space constraints or size deviations are encountered, the side length of the frame 1 can be finely adjusted within the sliding groove 10 by moving the movable block of the corner joint 4 to fit the actual installation environment. Then, the putty at the bottom of the frame 1 is used to embed the frame 9 to facilitate the fixing of the entire access panel. Fixed to the building substrate, the wear-resistant groove on the bottom surface of the pre-embedded frame 9 of the putty increases the friction with the putty, allowing the putty to adhere more firmly. After the putty dries, the access port is securely installed in place. Then, when the access port is in normal use, the access port cover 2 is placed on the abutment block 7. The primer 6 sprayed on the bottom surface of the access port cover 2 can prevent it from being corroded by contact with humid air or other corrosive substances. When maintenance work is required, the operator lifts the access port cover 2 and enters the access port to inspect and repair the relevant equipment or structure. This concludes the use of the pre-embedded square rounded corner access port.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
