[0026] To make the objectives, technical solutions, and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present utility model.

[0027] This specific embodiment provides a hidden door hinge to solve the technical problem of the relatively high cost of the hidden door hinge in the prior art.

[0028] Hereinafter, the embodiments will be described with reference to the drawings. In addition, the embodiments shown below do not impose any limitation on the content of the utility model described in the claims. Further, all the contents of the configurations shown in the following embodiments are not necessarily essential for the solution of the utility model described in the claims.

[0029] Refer to Figures 1 - 6, the present utility model provides a concealed door hinge, including a housing 1, a hinge 2, and a mounting member 3. Among them, the mounting member 3 is a stamping part, which greatly reduces the processing time of people and reduces the cost at the same time. The housing 1 is installed on the door leaf and is set in a U shape. A fifth groove for installing the housing is opened on the door leaf, and the housing 1 is installed in the fifth groove. The mounting member 3 is installed in the U-shaped cavity of the housing 1. The hinge 2 is rotatably installed on the mounting member 3. When people fix the hinge 2, they directly install the hinge 2 on the door frame without setting an installation groove on the door frame. Among them, in order to facilitate the installation of the mounting member 3 on the housing 1, a first threaded hole 31 is provided on the mounting member 3, and a second threaded hole is provided on the housing 1. A first fastener 4 is passed through the first threaded hole 31 and the second threaded hole, and the first fastener 4 can abut against the door leaf. When the housing 1 is installed on the door leaf, the distance between the housing 1 and the door leaf can be finely adjusted through the first fastener 4, thereby adjusting the position of the housing.

[0030] With this setting, by changing the casting part to a mounting member, the workload of people's processing is greatly reduced, thereby reducing the cost of the concealed door hinge, and at the same time, the position of the housing 1 can be finely adjusted.

[0031] In a further optimized solution, since the mounting member 3 is formed by stamping, the mounting member 3 is relatively thin in thickness. In order to ensure the connection strength between the mounting member 3 and the housing 1, a first boss 32 is provided on the side of the first threaded hole 31 close to the housing 1. In order to facilitate the installation of the first boss 32 of the mounting member 3 on the housing 1, a first groove 11 for accommodating the first boss 32 is provided on the bottom surface of the housing 1, providing an installation space for the first boss 32.

[0032] In a further optimized solution, a first waist-shaped hole 13 is provided on the housing 1, and the length direction of the first waist-shaped hole 13 is the same as the length direction of the housing 1, which is convenient for adjusting the height of the door leaf.

[0033] In a further optimized solution, in order to facilitate the adjustment of the position of the hinge 2, a second waist-shaped hole 23 is provided on the hinge 2, and the length direction of the second waist-shaped hole 23 is the same as the width direction of the hinge 2. In this way, people can slightly adjust the position of the hinge 2 during installation, which is convenient for adjusting the position of the hinge 2.

[0034] In a further optimized solution, in order to ensure that the mounting member 3 can be stably installed on the housing 1, a fourth fastener 6 is provided on the mounting member 3, and the fourth fastener 6 installs the mounting member 3 on the housing 1. Since only the first fastener 4 supports the mounting member 3, the mounting member 3 is prone to shaking on both sides and is not stable. After being fixed by the fourth fastener 6, the mounting member 3 is equivalent to being positioned on both sides and is more balanced. At the same time, the first fastener 4 and the fourth fastener 6 form a mutually acting supporting force, which can eliminate the thread clearance of the first fastener 4 and prevent the first fastener 4 from loosening.

[0035] For a further optimized solution, to facilitate hiding the connecting part on the hinge 2 within the mounting member 3, a receiving cavity 26 is provided on the mounting member 3. A connecting shaft 5 is provided between the mounting member 3 and the hinge 2. The hinge 2 is provided with a connecting part which is connected to the connecting shaft 5 so that the connecting part is received within the receiving cavity 26. When the door leaf is in the closed state, the connecting part of the hinge 2 is received within the receiving cavity 26.

[0036] For a further optimized solution, to facilitate fixing the housing 1, the housing 1 is provided with a first mounting hole 14. The second fastener is fixed to the door leaf through the second mounting hole 24, thereby firmly setting the housing 1 on the door leaf.

[0037] For a further optimized solution, to facilitate fixing the hinge 2, the hinge 2 is provided with a second mounting hole 24. The third fastener is fixed to the door frame through the second mounting hole 24. Since the hinge 2 not only has a second waist-shaped hole but also requires the second mounting hole 24 that cooperates with the third fastener, this avoids the problem of the hinge 2 moving during use.

[0038] For a further optimized solution, to ensure aesthetics, a second groove 21 is provided at the position where the second mounting hole 24 and the second waist-shaped hole 23 of the hinge 2 are installed, that is, the second mounting hole 24 and the second waist-shaped hole 23 are installed on the bottom surface of the second groove 21. The second protection plate 25 is installed within the second groove 21, and the second protection plate 25 ensures the flatness of the end face of the hinge.

[0039] For a further optimized solution, to facilitate people to lift the second protection plate 25, a third groove 22 is provided at the bottom of the second groove 21. Press the second protection plate 25 provided above the third groove 22 to lift the second protection plate 25. Specifically, the third groove 22 is installed at the corner position of the second groove 21, which facilitates lifting the second protection plate 25.

[0040] For a further optimized solution, to ensure the aesthetics of the end face of the housing 1, a first protection plate 15 is provided on the end face of the housing 1. The first protection plate 15 is snap-fitted with the housing 1, that is, the housing 1 is provided with a first snap groove, and the first protection plate 15 is provided with a first snap protrusion, and the first snap protrusion is snapped into the first snap groove.
