Description

Cranked arm linkage secret door

technical field

The invention relates to a curved arm connecting rod secret door.

Background technique

At present, for the installation of wooden side-hung secret doors on walls in architectural decoration projects, installation hardware such as hinges, pipe hinges, and cross hinges are mostly used. These hardwares have different installation disadvantages, which affect the overall installation effect and use function.

Conventional secret door installation hardware installation methods have the following disadvantages:

1. Installing the hidden door with hinges can solve the load-bearing problem of the hidden door, but the hinge shaft is exposed, which affects the aesthetics of the overall installation effect.

2. Installing the secret door on the pipe hinge can control the overall appearance effect very well, but the force and load bearing capacity of the pipe hinge is limited, and it is difficult to meet the load-bearing problem of the oversized and overweight secret door.

3. The hidden door installed with cross hinges has limited overall force and load bearing for the hidden door. At the same time, the technical requirements for the internal structure of the hidden door are relatively complicated, which will easily lead to cracking of the edge of the door leaf and high repair rate.

Contents of the invention

The object of the present invention is: to provide a kind of curved arm connecting rod secret door, which improves the installation of the wooden secret door, and fixes the upper and lower secret door connectors to the upper and lower ends of the wooden secret door, so as to affect the overall force of the secret door. The load bearing is guaranteed, it is in place at one time, and the repair rate is low.

The technical solution of the present invention is: a curved arm connecting rod secret door, which includes a guide rail, a connecting rod assembly, a secret door support rod, and a secret door. The inner side of the guide rail is a return-shaped chute, and the bottom of the chute is provided with a screw hole , the guide rail is fixed up and down with the frame body by wood screws along the edge of the frame; one end of the connecting rod assembly is connected to the guide rail in a rotating manner through a moving slider set in the chute, and the other end is rotated with the hidden door support rod through a fixed rotary knob Type connection to form a secret door connector; the secret door support rod is provided with screw holes, and the inner edge of the secret door is provided with corresponding screw holes, and the secret door support rod is fixed by wood screws along the upper and lower inner sides of the secret door to form a complete structure. The moving slider has buffer damping. The connecting rod assembly is two connecting rods of different lengths, the long connecting rod is connected to the middle of the hidden door support rod, and the short connecting rod is connected to the end of the hidden door supporting rod near the corner of the hidden door.

The advantages of the present invention are: the curved arm connecting rod secret door of the present invention, through matching and fixing the upper and lower two secret door connectors on the upper and lower ends of the wooden secret door, makes the installation of the wooden secret door convenient and affects the overall impact of the secret door. The force bearing is guaranteed, one-time in place, and the repair rate is low; at the same time, it solves the problem of exposed shafts, ensures the overall appearance effect, and solves the defects of commonly used hidden door hardware.

Description of drawings

The present invention will be further described below in conjunction with accompanying drawing and embodiment:

Fig. 1 is a schematic structural diagram of a secret door connector according to an embodiment of the present invention;

Fig. 2 is a schematic diagram of the installation structure of the embodiment of the present invention;

Among them: 1 guide rail; 2 moving slider; 3 connecting rod assembly; 4 fixed rotary knob; 5 hidden door support rod.

detailed description

Embodiment: As shown in Fig. 2, a kind of curved arm connecting rod hidden door, it comprises guide rail 1, connecting rod assembly 3, hidden door support bar 5, hidden door.

The inner side of the guide rail 1 is a return-shaped chute, and the bottom of the chute is provided with screw holes. The guide rail 1 is fixed up and down with the frame body by wood screws along the frame edge; It is rotatably connected with the guide rail 1, and the moving slider 2 has buffer damping; the other end is rotatably connected with the secret door support rod 5 through the fixed rotary knob 4 to form a secret door connecting piece. In order to ensure the force bearing of the door leaf, the connecting parts of the secret door are made of high-quality stainless steel; in order to ensure the smooth opening of the door leaf, the guide rail 1 and the frame must be molded and customized, and the mobile slider 2 with buffer damping must be molded to ensure that the door leaf is opened. It is smooth and silent in the closed state.

Hidden door support bar 5 is provided with screw hole, and the inboard edge position of hidden door is provided with corresponding screw hole, and hidden door support bar 5 is fixed to form complete structure by wood screw along the upper and lower inner sides of hidden door. When installing with the secret door, open the corresponding hole slot at the inner edge of the secret door, and directly connect the secret door connector with the door leaf and the frame with wood screws, which is convenient and quick.

The connection of the connecting rod assembly 3 and the fixed rotary knob 4 supports the overall stress of the secret door, and the opening and closing of the secret door is realized by the movement of the moving slider 2 with buffer damping in the guide rail 1 . The installation of the secret door connector, the secret door and the frame body only needs to be fixed by simple wood screws, and at the same time, according to the weight of the door leaf, the connecting rod assembly 3 that meets different force requirements can be selected for support, which is convenient, fast and secure.

The connecting rod assembly 3 is two connecting rods of different lengths, the long connecting rod is connected with the middle part of the hidden door support rod 5, and the short connecting rod is connected with the end of the hidden door supporting rod 5 near the corner edge of the hidden door. According to the difference of the weight of the door leaf, the connecting rod assembly 3 with different force and load bearing can be customized and replaced, and used together with the hidden door hardware.

It should be noted that the present invention, which has been fully described, is capable of many alternative and modified embodiments and is not limited to the specific examples described above. The above-mentioned embodiments are only used as illustrations of the present invention, rather than limiting the present invention. In a word, the protection scope of the present invention shall include those transformations, substitutions and modifications obvious to those skilled in the art.
