Abstract
Description
Technical Field
[0001] The utility model relates to a ceiling inspection opening and belongs to the field of decorative building materials. Background Art
[0002] A suspended ceiling refers to a decoration on the top of a house's living environment. Simply put, it refers to the decoration of the ceiling. It is an important part of interior decoration. It has the functions of heat preservation, heat insulation, sound insulation and sound absorption. It is also a hidden layer for electrical, ventilation and air conditioning, communications, fire protection, alarm pipeline equipment and other projects. In order to facilitate the inspection and maintenance of the above projects, inspection openings are generally reserved.
[0003] In the prior art, the inspection port is a square opening opened on the ceiling, with a cover plate fixed on the outer frame. During inspection, the cover plate is opened to carry out work. For aesthetic reasons, the cover plate is often in the same plane as the wall or ceiling. The more common ways to set the cover plate are snap connection and hinged connection.
[0004] However, the existing hinged fixed cover cannot be easily removed. When opened, one end of the cover naturally falls to a vertical position, which can easily cause bumps and affect the appearance. In addition, the inspection openings in the existing technology are mostly made of metal or plaster products, which are cumbersome to install and test the load-bearing capacity of the ceiling. They are easy to fall off after long-term use. Summary of the Invention
[0005] In view of this, the utility model provides a ceiling inspection opening to solve the above-mentioned problems existing in the prior art.
[0006] The technical solution of the utility model to solve the above technical problems is as follows:
[0007] A ceiling inspection opening comprises a frame and a cover plate. The outer side of the lower edge of the frame has an integral mounting edge. One end of the cover plate is hinged to the frame and can rotate axially along the hinge end. The cover plate and the frame are provided with a matching press-type elastic self-locking mechanism on the side away from the hinge end.
[0008] The cover plate is provided with a positioning rod, one end of the positioning rod is connected to the cover plate and can be rotated axially along the connection, and the other end of the positioning rod is provided with a hook.
[0009] On the basis of the above technical solution, the present invention can also be improved as follows.
[0010] Furthermore, two rotating shafts protruding outward are symmetrically provided on the upper edge of the cover plate, and the rotating shafts can be detachably engaged in the mounting grooves provided on the frame body to realize the hinged connection between the cover plate and the frame body.
[0011] Furthermore, a mounting hole is provided on the mounting edge.
[0012] Furthermore, the cover is made of PVC foam board; the frame is made of ABS material and is formed by a mold, which reduces costs and ensures stable product quality, making it suitable for mass production.
[0013] The beneficial effects of the utility model are:
[0014] The utility model has the advantages of simple structure, stable structure, not easy to deform, long service life and easy installation. When the cover is opened, the positioning rod provides a buffer to avoid damage to the cover due to collision and accidental falling. It can be widely used in office buildings, hotels, shopping malls, installation and engineering decoration and other fields. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 This is a schematic diagram of the structure of the ceiling inspection port of the utility model;
[0016] Figure 2 This is a schematic diagram of the open state of the ceiling inspection port of the utility model.
[0017] In the accompanying drawings, the components represented by the reference numerals are as follows:
[0018] 1. Frame, 2. Cover, 3. Mounting edge, 4. Press-type elastic self-locking mechanism, 5. Positioning rod, 6. Hook, 7. Rotating shaft, 8. Mounting slot. DETAILED DESCRIPTION
[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0020] like Figure 1 As shown, the ceiling inspection port includes a frame 1 and a cover plate 2. The outer side of the lower edge of the frame 1 has an integral mounting edge 3. One end of the cover plate 2 is hinged to the frame 1 and can rotate axially along the hinge end. The cover plate 2 and the frame 1 are provided with a matching press-type elastic self-locking mechanism 4 on the side away from the hinge end.
[0021] The cover plate 2 is provided with a positioning rod 5 , one end of which is connected to the cover plate 2 and can rotate axially along the connection, and the other end of the positioning rod 5 is provided with a hook 6 .
[0022] like Figure 2 As shown, when in use, the cover plate 2 is pressed to start the push-type elastic self-locking mechanism 4 to be stressed, and the cover plate 2 is released to fall naturally. At the same time, the hook 6 of the positioning rod 5 is hung on the inner edge of the frame 1 to provide a buffer, thereby avoiding the collision caused by the cover plate 2 rotating directly to a point perpendicular to the horizontal plane. The positioning rod 5 is bent inward to allow the cover plate 2 to continue to rotate downward to fully open the inspection port.
[0023] In another embodiment of the present invention, two rotating shafts 7 protruding outward are symmetrically provided on the upper edge of the cover 2. The rotating shafts 7 can be detachably engaged in the mounting grooves 8 provided on the frame 1 to realize the hinged connection between the cover 2 and the frame 1. After disassembly, the cover 2 can be removed from the frame 1. The detachable method can be to provide a mounting groove 8 with an opening on the frame 1 to accommodate the rotating shaft 7.
[0024] In another embodiment of the present invention, a mounting hole is provided on the mounting edge 3 , and the ceiling inspection opening can be fixed through the mounting hole by fixing members such as expansion bolts.
[0025] In another embodiment of the present invention, the cover plate 2 is a PVC foam board.
[0026] In another embodiment of the present invention, the frame 1 is made of ABS material.
[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
