Description

stone secret door

technical field

The invention relates to a stone secret door.

Background technique

There are many hidden projects in the decoration industry, and secret doors are one of them. There are following three kinds of secret door examples done at present, and each has some shortcomings.

1. The wooden door made of large wallpaper and latex paint will affect the overall effect; the height of the wall door in the same area is not uniform, the style is not coordinated, and there are too many holes in the wall to show chaos and irregularity. Then use wallpaper and latex paint to make it The door is difficult to close, will be deformed, and the seams are inconsistent with missing edges and corners.

2. If the wall with uneven wood veneer is used as a secret door, the conventional installation method cannot be realized, or it is obvious that there is a door, and the integrity cannot be achieved.

3. The opening angle of the hidden door on the stone wall does not meet the requirements of use, which brings hidden dangers in fire protection. Moreover, the traditional installation process is easy to damage the stone surface, which brings inconvenience to later maintenance.

Therefore, objectively, people put forward the following requirements for secret doors:

1. From the appearance point of view, it should be inconspicuous and have a door, and its external material and texture should be consistent with the large surface.

2. The operation is flexible and there is no excessive noise.

3. Meet the best requirements for use, without quality and safety hazards.

Contents of the invention

The purpose of the present invention is to provide a stone secret door, which is consistent with the large surface in appearance, has an inconspicuous door, has good concealment, and has a good overall effect; the opening angle can meet the use requirements, the opening and closing is smooth, and it is not damaged at all. The stone material complies with the fire inspection and acceptance specification, reducing maintenance costs in the later period.

The technical solution of the present invention is: a stone secret door, which includes a stone secret door leaf, the stone secret door leaf includes a stone panel and a foundation frame on the back of the stone panel, and the stone secret door leaf is movably installed in the dark through a bearing hinge assembly. On the base frame of the door opening, the bearing hinge assembly includes two hinge main connectors, four fixed shaft shells, two shaft rods, and a U-shaped power arm; the two hinge main connectors are respectively installed on the stone panel On the back base frame and the secret door opening base frame, each hinge main connector is respectively fixed with two upper and lower fixed shaft shells, and the shaft rod can be axially rotatably installed between the upper and lower fixed shaft shells. The U-shaped A shaft is connected to the left side of the power arm, and another shaft is connected to the right side of the U-shaped power arm.

Above-mentioned technical scheme is further explained below:

The fixed shaft housing is provided with an inner hole, and the inner holes of the upper and lower fixed shaft housings are arranged oppositely. The upper and lower ends of the shaft rod are respectively installed in the inner holes of the upper and lower fixed shaft housings. The inner holes of the shell can rotate axially.

A steel ball is arranged between the fixed axle housing and the axle rod. The steel ball is located in the inner hole of the fixed axle housing.

Both sides of the U-shaped power arm are respectively provided with adjustment holes, and angle adjustment bolts are arranged in the adjustment holes.

The advantages of the present invention are: the stone secret door of the present invention can realize secondary transmission through the bearing hinge assembly, so that the opening angle of the door leaf is greater than 180 degrees, and the opening and closing are smooth. When it is really needed, the opening success rate is 100%. It does not damage the stone at all, meets the fire acceptance specifications, and reduces maintenance costs in the later period. The invention can produce in batches to improve efficiency, save overall cost, and implement high-quality productized decoration; in order to realize the idea of productized decoration, the construction cost can be effectively reduced, and the aesthetic requirements of modern decoration can be met.
