A second fixing block is fixedly connected to the front facade of the first plate member, and a first fixing block is fixedly connected to the front facade of the second plate member. A bolt is installed on one side of the first fixing block close to the second fixing block, and a second assembly cylinder is installed on one side of the second fixing block close to the first fixing block. The second assembly cylinder is rotatably connected to the first assembly cylinder.

[0007] As a further scheme of the utility model: a first nut is installed on the side of the second fixing block, and a second nut is installed on the front surface of the second fixing block.

[0008] As a further scheme of the utility model: a shaft column is installed on the top of the first assembly cylinder.

[0009] As a further scheme of the utility model: a bolt is installed on the top of the shaft column, and the bolt is threadedly connected to the upper part of the inner cavity of the first assembly cylinder.

[0010] As a further scheme of the utility model: an inner shaft is installed in the inner cavity of the shaft column, bearing beads are installed between the shaft column and the inner shaft, and the shaft column and the inner shaft are rotatably connected.

[0011] As a further scheme of the utility model: a spiral ring is provided on the outer wall of the bolt.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In this utility model, when the second fixing block rotates, the second assembly cylinder rotates, and the shaft column connected to the inner cavity of the second assembly cylinder will rotate on the outer wall of the spiral ring. Similarly, when the first assembly cylinder rotates, the shaft column connected to the inner cavity of the first assembly cylinder will also rotate on the outer wall part of the spiral ring. By using this method, lubricating oil can be locked between the shaft column and the spiral ring, and its structure is more optimized and the design is more reasonable.

[0014] In this utility model, the first assembly cylinder connected to one end of the first fixing block and the second assembly cylinder connected to one end of the second fixing block are rotatably connected. The shaft column passes through the axes of the first assembly cylinder and the second assembly cylinder, and at the same time, the bolt at the top of the shaft column cooperates with the spiral ring for threaded connection with the upper part of the inner wall of the first assembly cylinder.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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 embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 3, in the embodiment of the present utility model, a silent hinge for a bedroom door includes a first plate member 1 and a second plate member 2. A second fixing block 6 is fixedly connected to the front facade of the first plate member 1, and a first fixing block 3 is fixedly connected to the front facade of the second plate member 2. A bolt 9 is installed on the side of the first fixing block 3 close to the second fixing block 6, and a second assembly cylinder 5 is installed on the side of the second fixing block 6 close to the first fixing block 3. The second assembly cylinder 5 is rotatably connected to the first assembly cylinder 4. A first nut 7 is installed on the side of the second fixing block 6, and a second nut 8 is installed on the front surface of the second fixing block 6. A shaft column 11 is installed on the top of the first assembly cylinder 4, and a bolt 9 is installed on the top of the shaft column 11. The bolt 9 is threadedly connected to the upper part of the inner cavity of the first assembly cylinder 4. An inner shaft 13 is installed in the inner cavity of the shaft column 11, and bearing beads 12 are installed between the shaft column 11 and the inner shaft 13. The shaft column 11 is rotatably connected to the inner shaft 13, and a thread ring 14 is provided on the outer wall of the bolt 9.

[0021] The working principle of the present utility model is:

[0022] During use, the second fixing block 6 and the first fixing block 3 are respectively fixed on the front surfaces of the first plate member 1 and the second plate member 2 for hinge use;

[0023] The first assembly cylinder 4 connected to one end of the first fixing block 3 and the second assembly cylinder 5 connected to one end of the second fixing block 6 are rotatably connected. The shaft column 11 passes through the axes of the first assembly cylinder 4 and the second assembly cylinder 5. At the same time, the bolt 9 at the top of the shaft column 11 cooperates with the thread ring 14 to be threadedly connected to the upper part of the inner wall of the first assembly cylinder 4;

[0024] The bearing beads 12 installed between the shaft column 11 and the inner shaft 13 play a role in rotational cooperation;

[0025] When the second fixing block 6 rotates, the second assembly cylinder 5 rotates, and the shaft column 11 connected to the inner cavity of the second assembly cylinder 5 will rotate on the outer wall of the thread ring 14. Similarly, when the first assembly cylinder 4 rotates, the shaft column 11 connected to the inner cavity of the first assembly cylinder 4 will also rotate on the outer wall part of the thread ring 14. In this way, lubricating oil can be locked between the shaft column 11 and the thread ring 14.

[0026] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
