Description

Technical Field

[0002] Cleanroom panels, also known as purification panels, are composite panels made of color-coated panels, stainless steel, aluminum alloy panels and other materials as surface materials. They have unique dust-proof, anti-static, and antibacterial effects and are used in clean engineering fields with strict requirements on indoor environment, such as pharmaceuticals, food, aerospace, precision instrument manufacturing and scientific research.

[0003] Due to the different sizes required, when the floor space is large, in order to facilitate transportation, the required structural parts are usually divided into multiple clean panels; in order to facilitate assembly, multiple clean panels are connected by connectors; however, when it comes to the connection at the corners between the clean panels, since the ends of the panels are all vertical working surfaces, and the connectors connecting the clean panels usually connect the clean panels seamlessly, the clean panels cannot be ventilated during the plug-in process, and the internal air cannot be discharged in time, resulting in a decrease in the installation quality of the clean panels. The retained air inside increases the resistance during the plug-in installation process. If the retained air is not discharged in time, the clean panels are easily susceptible to corrosion and oxidation in high temperature or humid environments, thereby further reducing the service life of the clean panels.

4. The clean board installation keel corner according to claim 2, characterized in that: One end of the first connector away from the first fixing member has a first guiding surface inclined inwardly, and one end of the first connector away from the first fixing member has a second guiding surface inclined inwardly.

5. The clean board installation keel corner according to claim 2, characterized in that: The second plug-in frame includes a second fixing member, a second connector and a second plug-in member; the second fixing member is a 90° bent structure, and the second connector and the second plug-in member are symmetrically connected to the two ends of the second fixing member, so that a vertical structure is formed between the second connector and the second plug-in member.

6. The clean board installation keel corner according to claim 5, characterized in that: The second connector has at least one third protrusion on a side facing the connecting member, and the third protrusion can abut against the inner wall of the third profile to form a first locking portion for locking and connecting the third profile; the second connector has at least one fourth protrusion on a side facing the connecting member, and the fourth protrusion can abut against the inner wall of the fourth profile to form a second locking portion for locking and connecting the fourth profile; a second connecting profile is connected between the second connector and the second connector.

7. The clean board installation keel corner according to claim 5, characterized in that: The end of the second connector away from the second fixing member has a third guiding surface inclined inwardly, and the end of the second connector away from the second fixing member has a fourth guiding surface inclined inwardly.

8. The clean board installation keel corner according to claim 5, characterized in that: The connecting member includes a first connecting member and a second connecting member connected to form an integrated structure, the first connecting member and the second connecting member are vertically connected, one side of the first connecting member is connected to the first fixing member, and the other side of the first connecting member is connected to the second fixing member, one side of the second connecting member is connected to the first fixing member, and the other side of the second connecting member is connected to the second fixing member.

9. The clean board installation keel corner according to claim 5, characterized in that: The first plug-in frame also includes a first connecting surface and a second connecting surface; the first connecting surface is vertically connected to one side of the first plug-in component and extends inward; the second connecting surface is vertically connected to one side of the first plug-in component and extends inward.
