Abstract
Description
Technical Field
[0001] This utility model relates to the field of building door and window technology, and in particular to a cover plate structure that can be suspended after being opened. Background Technology
[0002] In certain types of doors and windows, such as motorized lift windows, there is a compartment for housing components such as motors and control systems. For ease of routine maintenance and repair, this compartment needs an opening. This opening is usually fitted with a cover that is normally closed and only opened for maintenance. However, once opened, the cover may sag due to its own weight, obstructing the opening and causing inconvenience for maintenance personnel. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model discloses a cover plate structure that can be suspended after being opened.
[0004] The specific technical solution is as follows:
[0005] A cover structure that can be suspended after opening includes a cover and a cabin. A hook assembly is vertically arranged downward at one end of the cover, and a hook groove is provided on the open end face of the cabin. The hook assembly of the cover is inserted into the hook groove of the cabin and rotated to engage. After the cover is opened, it is horizontally suspended outside the opening of the cabin.
[0006] The hook assembly includes an arc surface A, a circular pivot, and a straight surface A. The arc surface A is a quarter-circle arc and extends horizontally to the right to the straight surface A. The end of the straight surface A is the circular pivot. The circular pivot is concentric with the arc surface A.
[0007] The hook groove includes a support surface, a straight surface B, an arc surface B, a straight surface C, and an arc surface C. The hook groove is U-shaped, with one end connected to the support surface via the vertical straight surface B. The support surface is a protruding structure extending horizontally to the left, supporting the rotation of the straight surface A and the circular pivot. The other end of the hook groove extends to the left via the arc surface B, forming a quarter-circle arc, concentric with the arc surface A. The arc surface B connects to the horizontally left-facing straight surface C. The radius of the arc surface B is larger than the radius of the arc surface A, allowing the cover plate to rotate around the circular pivot.
[0008] The straight surface C is connected to the downward-extending arc surface C, which bends inward to limit the hook assembly and prevent it from coming off.
[0009] The cover plate has a protrusion A at its horizontal end, and a protrusion B extends horizontally to the right side of the hook groove of the cabin; when the cover plate is opened, protrusion A is hooked on protrusion B.
[0010] Pull the cover away from the cabin. When the circular pivot contacts the straight surface B, protrusions A and B separate.
[0011] Compared with the prior art, the present invention has the following beneficial technical effects:
[0012] This invention utilizes a hook assembly on the cover plate that inserts into the hook groove of the cabin and rotates to engage, allowing the cover plate to be opened and then horizontally suspended outside the cabin opening. When the cover plate is in a horizontal position, pushing it towards the cabin causes it to slide until arc surface A contacts arc surface C, at which point the cover plate remains horizontally suspended. No other parts are needed; the opening, closing, and suspension of the cover plate are achieved using the structure of the aluminum profile itself, facilitating maintenance operations.

[0017] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the accompanying drawings.
[0018] This utility model provides a cover structure that can be suspended after opening, including a cover plate 1 and a cabin 2. A hook assembly is vertically arranged downward at one end of the cover plate 1, and a hook groove is provided on the open end face of the cabin 2. The hook assembly of the cover plate 1 is inserted into the hook groove of the cabin 2 and rotated to engage. After the cover plate 1 is opened, it is horizontally suspended outside the opening of the cabin 2. The hook assembly includes an arc surface A103, a circular pivot 101, and a straight surface A102. The arc surface A103 is a quarter-circle arc and extends horizontally to the right to the straight surface A102. The end of the straight surface A102 is the circular pivot 101. The circular pivot 101 is concentric with the arc surface A103. The hook groove includes a support surface 201, a straight surface B202, and an arc surface B203. The cover plate 1 has a straight surface C205 and an arc surface C206. The hook groove is U-shaped, with one end connected to the support surface 201 via a vertical straight surface B202. The support surface 201 is a protruding structure extending horizontally to the left, supporting the rotation of the straight surface A102 and the circular rotating shaft 101. The other end of the hook groove extends to the left via an arc surface B203, forming a quarter-circle arc, concentric with the arc surface A103. The arc surface B203 connects to the horizontally left-facing straight surface C205, and the straight surface C205 connects to the downward-extending arc surface C206. The arc surface C206 bends inward to limit the hook assembly and prevent it from coming off. The radius of the arc surface B203 is larger than the radius of the arc surface A103, allowing the cover plate 1 to rotate around the circular rotating shaft 101.
[0019] A protrusion A104 is provided at the horizontal end of the cover plate 1, and a protrusion B204 extends horizontally to the right side of the hook groove of the cabin 2. When the cover plate 1 is opened, the protrusion A104 is hooked on the protrusion B204. When the cover plate 1 is pulled away from the cabin 2, the protrusion A104 and the protrusion B204 separate just when the circular rotating shaft 101 contacts the straight surface B202.
[0020] When using it, please follow these steps:
[0021] (1) When the cover plate 1 is closed to the cabin 2, the circular pivot 101, the straight surface A102 and the arc surface A103 are surrounded by the supporting surface 201, the straight surface B202 and the arc surface B203, so that the cover plate 1 will not fall off and can maintain a static vertical state under its own weight, such as Figure 1 As shown;
[0022] (2) When the cover plate 1 is in the open state, it rotates 90° counterclockwise around the circular axis 101 to reach a horizontal state, exposing the opening of the compartment 2. The support surface 201 supports the circular axis 101, preventing the cover plate 1 from falling off. However, if the cover plate 1 is released at this time, under its own weight, it will rotate clockwise around the circular axis 101 and return to a vertical state, such as... Figure 2 As shown;
[0023] (3) When cover 1 is open and needs to continuously expose the opening of cabin 2, cover 1 should be suspended. After cover 1 reaches a horizontal state, push cover 1 towards cabin 2 until it stops when arc surface A103 contacts arc surface C206. Straight surface A102 coincides with straight surface C205, and cabin 2 applies a downward pressure to cover 1 at this point. Protrusion A104 is located on protrusion B204, and cabin 2 applies an upward support force to cover 1 at this point. The pressure and support force on cover 1 are balanced with its own weight, and cover 1 remains horizontal, i.e., it reaches a suspended state, exposing the opening of cabin 2, such as... Figure 3 As shown;
[0024] If it is necessary to close the cover plate 1 at the opening of the cabin 2, simply pull the cover plate 1 away from the cabin 2 until the circular pivot 101 contacts the straight surface B202 and release it. Under its own weight, the cover plate 1 can rotate clockwise around the circular pivot 101 and return to the vertical state, thereby closing the opening.
