Detailed Embodiment

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.

[0023] As shown Figures 1-6 in the figure, a hinge includes a first seat body 1 and a second seat body 2. A swing arm 3 is connected between the first seat body 1 and the second seat body 2. The first seat body 1 and the second seat body 2 are both rotatably arranged relative to the swing arm 3. One end of the swing arm 3 is hinged to the first seat body 1 through a first hinge shaft 31, and the other end of the swing arm 3 is hinged to the second seat body 2 through a second hinge shaft 32. A limiting rod 11 is arranged on one side of the first seat body 1 where the swing arm 3 is located. Two abutting blocks 4 are arranged on both sides of the swing arm 3. A locking part 5 which is in locking or separating cooperation with the abutting blocks 4 is arranged on the second seat body 2; a bending part 41 is arranged at the end of the abutting block 4 close to the second seat body 2, and a clamping groove 42 is formed above the bending part 41 of the abutting block 4. A receiving groove 51 which is matched with the bending part 41 and a clamping block 52 which is matched with the clamping groove 42 are arranged on the locking part 5; arc-shaped grooves 12 are formed on both inner sides of the first seat body 1, and guide rollers located in the arc-shaped grooves 12 are arranged on the swing arm 3; the swing arm 3 is generally C-shaped, and the abutting blocks 4 are adapted to the side shape of the swing arm 3; a cushion block part 13 which abuts against the abutting blocks 4 is arranged on the first seat body 1; a vertical adjusting hole 14 is arranged on the first seat body 1, and a horizontal adjusting hole 21 and a depth adjusting hole 22 are arranged on the second seat body 2; the rotation angles of the first seat body 1 and the second seat body 2 relative to the swing arm 3 are both 90 degrees.

[0024] By adopting the above technical solution, in the present utility model, during specific installation, the first seat body 1 is installed on the door frame, and the second seat body 2 is installed on the door leaf. Mounting holes for fixed installation are arranged on both the first seat body 1 and the second seat body 2. Among them, at least one vertical adjusting hole 14 is arranged on the first seat body 1, which enables the hinge to be adjustable in the vertical direction during installation, facilitating the accuracy of the installation position. And at least one horizontal adjusting hole 21 and at least one depth adjusting hole 22 are arranged on the second seat body 2, which can realize the adjustable setting of the hinge in the horizontal direction and the depth direction, making the installation have better position accuracy.

[0025] The main innovation point of the present utility model lies in that a swing arm 3 is provided, which can realize the large-angle rotation adjustment of the hinge. Specifically, the second seat body 2 can rotate 90 degrees relative to the swing arm 3, and the swing arm 3 can also rotate 90 degrees relative to the first seat body 1. During use, by rotating the door leaf, first, the second seat body 2 rotates 90 degrees relative to the swing arm 3. After the locking part 5 and the abutting blocks 4 are in limiting cooperation, the second seat body 2 drives the swing arm 3 to continue rotating 90 degrees relative to the first seat body 1. In this way, the 180-degree large-angle rotation adjustment of the door leaf relative to the door frame can be realized.

[0026] When the bending part 41 is located in the accommodating groove 51, the swing arm 3 does not rotate relative to the first seat body 1, and the second seat body 2 does not rotate relative to the swing arm 3 either. When the bending part 41 disengages from the accommodating groove 51, the second seat body 2 rotates relative to the swing arm 3 at this time. When the clamping block 52 is inserted into the clamping groove 42, the second seat body 2 will drive the swing arm 3 to rotate relative to the first seat body 1. Among them, the abutting block 4 can be connected to the swing arm 3 through a connecting piece, such as a pin shaft, a screw, etc., or can be integrally provided with the swing arm 3. And by providing an integral swing arm 3, it has good structural strength, making the overall strength of the hinge better and the service life longer.

[0027] By providing the limiting rod 11, it can provide a limiting effect for the rotation of the swing arm 3 relative to the first seat body 1, and also increases the overall connection strength of the first seat body 1. Of course, the setting of the arc-shaped groove 12 also provides a guiding and stroke control function for the rotation of the swing arm 3. The combined setting of the limiting rod 11 and the arc-shaped groove 12 further ensures the limiting effect of the swing arm 3. The setting of the cushion block part 13 can abut against the swing arm 3 when the swing arm 3 rotates to the maximum position, providing a certain contact buffer and noise reduction effect.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
