[0034] Embodiment 1

[0035] As Figures 1 to 7 shown, an adjustable installation angle door closing device includes a door closing device main body 1 and an installation component 2. A rotating shaft 11 is provided on the door closing device main body 1. The installation component 2 includes a transmission member 21 and a mounting seat 22;

[0036] Square grooves are symmetrically opened at both ends of the rotating shaft 11. The end of the transmission member 21 is square. After the transmission member 21 is inserted into any one of the square grooves, a fixing screw passes through the square groove at the other end and is connected to the transmission member 21, so that the transmission member 21 is connected to the rotating shaft 11;

[0037] The mounting seat 22 is rotatably connected to the transmission member 21, and the mounting seat 22 and the transmission member 21 are connected through a fastening structure, so that the mounting seat 22 and the transmission member 21 are fixed through the fastening structure in the completed rotation adjustment state; thus solving the problem of the installation angle of the door closer.

[0038] Specifically, a movable groove 221 is provided at the bottom of the mounting seat 22. An movable arm 211 is provided at the upper end of the transmission member 21. A rotating part 212 is provided at the center of the movable arm 211. The rotating part 212 is rotationally matched with the movable groove 221. It should be understood that the rotating part 212 is an arc-shaped structure, and the arc surface of the rotating part 212 cooperates with the movable groove 221, so that the movable arm 211 is rotatably arranged in the movable groove 221.

[0039] In addition, the rotating part 212 can also directly move along the movable groove 221, enabling the movable arm 211 to move linearly along the movable groove 221. When the fastening structure is in the loosened state, the mounting seat 22 can move on the transmission part 21, thereby adjusting the position of the door body left and right.

[0040] The fastening structure includes at least two setscrews 3. Both ends of the movable arm 211 are provided with the setscrews 3, and the setscrews 3 are respectively connected to the movable arm 211 and the mounting seat 22.

[0041] Specifically, a first screw hole 222 is formed on the side surface of the mounting seat 22. The setscrew 3 is screwed into the first screw hole 222, and the end of the setscrew 3 abuts against the movable arm 211. Among them, a limiting groove 213 is provided along the length direction of the movable arm 211, and the end of the setscrew 3 abuts against the limiting groove 213. A second screw hole 214 penetrates through the movable arm 211. The setscrew 3 is screwed into the second screw hole 214, and the end of the setscrew 3 abuts against the wall surface of the movable groove 221. Among them, an adjustment through hole 223 corresponding to the second screw hole 214 is provided on the side surface of the mounting seat 22 to enable a tool to pass through the adjustment through hole 223 to drive the setscrew 3.

[0042] In this embodiment, the fastening structure includes four setscrews 3, including a first setscrew 3a, a second setscrew 3b, a third setscrew 3c, and a fourth setscrew 3d. The internal hexagonal grooves at the driving ends of the first setscrew 3a, the second setscrew 3b, the third setscrew 3c, and the fourth setscrew 3d are all arranged in the same direction.

[0043] Among them, 2 first screw holes 222 are formed on one side surface of the mounting seat 22. The first setscrew 3a and the fourth setscrew 3d are respectively screwed into the 2 first screw holes 222. The first setscrew 3a and the fourth setscrew 3d respectively abut against both ends of the limiting groove 213. 2 second screw holes 214 penetrate through the movable arm 211. The second setscrew 3b and the third setscrew 3c are respectively screwed into the 2 second screw holes 214. The second setscrew 3b and the third setscrew 3c abut against the wall surface of the movable groove 221. It should be understood that when adjusting the installation angle of the door body, the mounting seat 22 is rotated to a certain angle, and then each setscrew 3 is rotated respectively, so that the mutual acting forces between the first setscrew 3a, the fourth setscrew 3d and the second setscrew 3b, the third setscrew 3c clamp the mounting seat 22 to achieve fixation. When the angle needs to be adjusted, only the setscrew 3 in the corresponding direction needs to be loosened. After adjusting to the appropriate position, then tighten each setscrew 3 to fix the mounting seat 22.

[0044] Embodiment 2

The first set screw 3a, the second set screw 3b, the third set screw 3c, and the fourth set screw 3d are respectively arranged in the four first screw holes 222. The first set screw 3a, the second set screw 3b, the third set screw 3c, and the fourth set screw 3d respectively correspond to the left and right ends of the front and rear sides of the movable arm 211, so that the mutual acting forces between the first set screw 3a and the third set screw 3c and between the fourth set screw 3d and the second set screw 3b clamp and fix the mounting base 22.

[0046] It should be understood that for this structure, each set screw 3 needs to be loosened on both side surfaces of the mounting base 22.

[0047] In addition, mounting holes are provided at both ends of the mounting base 22, and the mounting base 22 is fixed by connecting with the door body through these mounting holes.
