A building roof access hatch

Abstract

This utility model discloses a roof access panel, comprising a frame, an insulation cover rotatably connected to the back of the frame, a protective cover fixedly connected to the back of the insulation cover, a connecting plate fixedly connected to the bottom of the frame, and guide rails fixedly connected to both sides of the inner cavity of the frame. Positioning holes are formed on the surface of the guide rails, and a slide is slidably connected to the surface of the guide rails. A threaded locking rod is threaded through the side of the slide away from the guide rail. This utility model allows the insulation cover to be flipped, causing it to move via a support rod, resulting in the back of the slide fitting against a baffle. Rotating a torsion bar then causes the threaded locking rod to thread with the slide, allowing it to enter the inner cavity of the positioning hole. This achieves support for the roof access panel cover through a support structure, avoiding the need for periodic sealing checks on the gas struts and reducing the maintenance cost of the roof access panel.

Description

Technical Field

[0001] This utility model belongs to the field of building roof maintenance technology, and in particular relates to a building roof maintenance port. Background Technology

[0002] Roof access panels provide access to the interior space of a building for maintenance personnel, facilitating the inspection, repair, maintenance, and replacement of various equipment, pipes, and wiring on the roof. To make it easier for users to open and close the roof access panel cover, gas struts are usually installed to support the cover, assisting in opening and closing the access panel cover, keeping it open, and reducing impact noise.

[0003] When using gas struts to support the cover plate, users need to periodically check the gas struts for sealing. It is quite troublesome for users to frequently climb up to the roof access panel for inspection. Therefore, there is a need for a building roof access panel that can be supported by a support structure, avoiding the need for periodic sealing checks of the gas struts and reducing the maintenance cost of the roof access panel. Utility Model Content

[0004] The purpose of this utility model is to provide a roof access panel for buildings, which can be supported by a support structure to support the cover plate of the roof access panel, thereby avoiding the need for regular sealing checks of the gas struts, reducing the maintenance cost of the roof access panel, and solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A building roof inspection port includes a frame, an insulation cover rotatably connected to the back of the frame, a protective cover fixedly connected to the back of the insulation cover, a connecting plate fixedly connected to the bottom of the frame, guide rails fixedly connected to both sides of the inner cavity of the frame, positioning holes opened on the surface of the guide rails, a slide rail slidably connected to the surface of the guide rails, a threaded locking rod penetrating the side of the slide rail away from the guide rail, the threaded locking rod penetrating the slide rail and matching the positioning hole, the threaded locking rod being threadedly connected to the slide rail, a torsion bar fixedly connected to the end of the threaded locking rod away from the slide rail, a support rod rotatably connected to the side of the slide rail away from the guide rail, the other end of the support rod being rotatably connected to the insulation cover, a baffle fixedly connected to the back of the guide rail, and a pin assembly fixedly connected to the front of the insulation cover.

[0006] Preferably, the bottom of the connecting plate has four symmetrical mounting holes, and the corners of the connecting plate are rounded.

[0007] Preferably, a sealing gasket is fixedly connected to the top of the frame, and the sealing gasket is frame-shaped.

[0008] Preferably, the surface of the torsion bar is provided with anti-slip texture, the torsion bar is located on the front of the support rod, and the torsion bar is cylindrical.

[0009] Preferably, the front of the inner cavity of the frame is provided with an opening, and the pin assembly is adapted to the opening on the front of the inner cavity of the frame.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model flips the insulation cover, causing the insulation cover to move along the slide via the support rod, so that the back of the slide is in contact with the baffle. At this time, rotating the torsion bar causes the threaded clamp to move with the slide thread, so that the threaded clamp enters the inner cavity of the positioning hole. This allows the cover plate of the roof access port to be supported by the support structure, avoiding the need to regularly check the sealing of the gas strut and reducing the maintenance cost of the roof access port.

[0012] 2. By setting a sealing gasket, when the heat insulation cover is placed on top of the frame, the sealing gasket will cover the gap between the frame and the heat insulation cover, preventing rainwater from entering the inner cavity of the frame and increasing the sealing performance of the heat insulation cover.

[0020] In the following description, embodiments of the building roof access panel of this utility model will be described with reference to the accompanying drawings. Example 1

[0021] Figure 1-4This invention illustrates a roof access panel for a building, comprising a frame 1. A sealing gasket 14 is fixedly connected to the top of the frame 1. The sealing gasket 14 is frame-shaped. When the insulation cover 2 is placed on top of the frame 1, the sealing gasket 14 blocks the gap between the frame 1 and the insulation cover 2, preventing rainwater from entering the inner cavity of the frame 1 and increasing the sealing performance of the insulation cover 2. The insulation cover 2 is rotatably connected to the back of the frame 1, and a protective cover 3 is fixedly connected to the back of the insulation cover 2. A connecting plate 4 is fixedly connected to the bottom of the frame 1. The bottom of the connecting plate 4 has four symmetrical mounting holes 13. The edges of the connecting plate 4... The corners are rounded. Guide rails 5 are fixedly connected to both sides of the inner cavity of the frame 1. Positioning holes 6 are opened on the surface of the guide rails 5. A slide 7 is slidably connected to the surface of the guide rails 5. A threaded rod 8 is provided through the side of the slide 7 away from the guide rails 5. The threaded rod 8 passes through the slide 7 and is adapted to the positioning holes 6. The threaded rod 8 is threadedly connected to the slide 7. A torsion bar 9 is fixedly connected to the end of the threaded rod 8 away from the slide 7. A support rod 10 is rotatably connected to the side of the slide 7 away from the guide rails 5. The other end of the support rod 10 is rotatably connected to the heat insulation cover 2. A baffle 11 is fixedly connected to the back of the guide rails 5. A pin assembly 12 is fixedly connected to the front of the heat insulation cover 2. Example 2

[0022] Figure 1-4 This invention illustrates a roof access panel for a building, comprising a frame 1. An opening is formed on the front of the inner cavity of the frame 1. A pin assembly 12 is fitted to the opening on the front of the inner cavity of the frame 1. An insulation cover 2 is rotatably connected to the back of the frame 1. A protective cover 3 is fixedly connected to the back of the insulation cover 2. A connecting plate 4 is fixedly connected to the bottom of the frame 1. Guide rails 5 are fixedly connected to both sides of the inner cavity of the frame 1. Positioning holes 6 are formed on the surface of the guide rails 5. A sliding carriage 7 is slidably connected to the surface of the guide rails 5, with the side of the sliding carriage 7 away from the guide rail 5 having a through-hole. A threaded clamp 8 passes through the slide 7 and is adapted to the positioning hole 6. The threaded clamp 8 is threadedly connected to the slide 7. A torsion bar 9 is fixedly connected to the end of the threaded clamp 8 away from the slide 7. The surface of the torsion bar 9 is provided with anti-slip texture. The torsion bar 9 is located on the front of the support rod 10. The torsion bar 9 is cylindrical. The support rod 10 is rotatably connected to the side of the slide 7 away from the guide rail 5. The other end of the support rod 10 is rotatably connected to the heat preservation cover 2. A baffle 11 is fixedly connected to the back of the guide rail 5. A pin assembly 12 is fixedly connected to the front of the heat preservation cover 2.

[0023] Working principle: When using this utility model, the user flips the insulation cover 2, causing the insulation cover 2 to move the slide 7 via the support rod 10. The slide 7 slides on the surface of the guide rail 5. When the back of the slide 7 is in contact with the baffle 11, the user rotates the torsion rod 9, causing the threaded clamp 8 to move threadedly with the slide 7. This allows the threaded clamp 8 to enter the inner cavity of the positioning hole 6, thereby limiting the slide 7. At this time, the support rod 10 supports the insulation cover 2, avoiding the need for regular sealing checks on the gas struts and reducing the maintenance cost of the roof access panel. With the setting of the sealing gasket 14, when the insulation cover 2 is placed on top of the frame 1, the sealing gasket 14 fills the gap between the frame 1 and the insulation cover 2, preventing rainwater from entering the inner cavity of the frame 1 and increasing the sealing performance of the insulation cover 2.

[0024] In summary: By flipping the insulation cover 2, the insulation cover 2 moves the slide 7 via the support rod 10, causing the back of the slide 7 to fit against the baffle 11. At this time, rotating the torsion rod 9 causes the threaded clamp 8 to move threadedly with the slide 7, allowing the threaded clamp 8 to enter the inner cavity of the positioning hole 6. This allows the cover of the roof access panel to be supported by the support structure, avoiding the need for periodic sealing checks on the gas struts and reducing the maintenance cost of the roof access panel.
