Description

Technical Field

[0001] The utility model relates to the field of hinges, and more specifically, it relates to a small-angle buffer hinge for three-dimensional adjustment of thick doors. Background Art

[0002] A hinge, also known as a hinge joint, is a mechanical device used to connect two solids and allow relative rotation between them; hinges are mainly installed on doors and windows, while hinges are more installed on cabinets; in order to let people enjoy better, a hydraulic hinge (also known as a damping hinge) has emerged, and its characteristic is to bring a buffering function when the cabinet door is closed, minimizing the noise generated by the collision between the cabinet door and the cabinet body when the cabinet door is closed.

[0003] The hinge includes a hinge cup installed on the cabinet door and a hinge seat installed on the side plate of the cabinet body, and the hinge arm on the hinge seat extends outward and is hinged to the hinge cup; when opening or closing the cabinet door, the hinge cup rotates relative to the hinge arm with the cabinet door, so the hinge cup plays a supporting role for the cabinet door; the hinge cup of the existing hinge has insufficient strength, resulting in insufficient load-bearing capacity of the hinge cup, which easily causes the hinge cup to tear and damage, affecting the service life of the hinge.

Detailed Description of the Preferred Embodiment

[0028] Referring to the attached Figures 1 to 9 A further detailed description is given of a small-angle buffer hinge with three-dimensional adjustability for thick doors according to the present invention.

[0029] A small-angle buffer hinge with three-dimensional adjustability for thick doors includes a hinge body 1 installed on the side plate of the cabinet and a hinge cup 2 installed on the cabinet door; the hinge body 1 includes a three-dimensional adjustable base 11 installed on the side plate of the cabinet, and a hinge arm 12 is arranged on the three-dimensional adjustable base 11;

[0030] The front end of the hinge arm 12 is hinged with a front support arm 3, the front support arm 3 is hinged with the front end of the cup groove 21 of the hinge cup 2 through a front connecting arm 4, and a buffer 7 is arranged on the front connecting arm 4, and one end of the buffer 7 abuts against the front support arm 3;

[0031] The rear end of the hinge arm 12 is hinged with a rear support arm 5, and a rear connecting arm 6 is hinged at the middle position of the front support arm 3. One end of the rear connecting arm 6 is hinged with the rear support arm 5, and the other end is hinged with the rear end of the cup groove 21 of the hinge cup 2 through a rotating shaft 61;

[0032] A support block 8 is provided at the rear end of the cup groove 21 of the hinge cup 2, and a rotating groove 81 adapted to the rotating shaft 61 is provided on the support block 8; the front end of the hinge cup 2 extends forward with a reinforcing flange 22, and the reinforcing flange 22 is bent downward with a reinforcing hem 23;

[0033] At the rear end of the cup groove 21 of the hinge cup 2 of this hinge, there is provided a support block 8 for supporting the rotating shaft 61, and a rotating groove 81 adapted to the rotating shaft 61 is provided on the support block 8, so that the rotating shaft 61 for connecting the rear connecting arm 6 is rotatably arranged on the support block 8, avoiding the middle of the rotating shaft 61 being suspended, reducing the pressure on the cup wall of the hinge cup 2; at the same time, the front end of the hinge cup 2 extends forward with a reinforcing flange 22, and the reinforcing flange 22 is bent downward with a reinforcing hem 23, further improving the strength of the hinge cup 2; avoiding the hinge cup 2 from being torn and damaged, and improving the service life of the hinge;

[0034] Wherein a clamping groove 24 is opened at the rear end of the cup groove 21 of the hinge cup 2, and a clamping portion 82 adapted to the opening groove is provided at the lower end of the support block 8. The support block 8 is made of plastic material. During assembly, it only needs to be clamped into the clamping groove 24 of the hinge cup 2 through the clamping portion 82 to complete the assembly, and the operation is simple and convenient.

[0035] Wherein a U-shaped double needle 25 is connected to the front end of the cup groove 21 of the hinge cup 2, and the front end of the front connecting arm 4 is rotatably arranged on the upper arm of the U-shaped double needle 25 to effectively control the swing degree of the hinge cup 2, so that the hinge cup 2 can swing more stably and reliably relative to the hinge arm 12, improving the stability performance of the product structure.

[0036] Wherein the three-dimensional adjustment base 11 includes a fixing plate 111 fixedly installed on the cabinet side plate and an adjustment plate 112. The adjustment plate 112 is provided with left and right waist-shaped adjustment holes 1121, and left and right eccentric adjustment members 1122 adapted thereto are installed in the left and right waist-shaped adjustment holes 1121. The left and right eccentric adjustment members 1122 pass through the left and right waist-shaped adjustment holes 1121 and are rotatably arranged on the fixing plate 111; when the left and right eccentric adjustment members 1122 are rotated, the left and right eccentric adjustment members 1122 will push the adjustment plate 112 to move left and right relative to the fixing plate 111, realizing the left and right position adjustment of the hinge.

[0037] The hinge arm 12 includes a support base 121 and a hinge arm body 122. A height adjustment screw 1221 is threadedly connected to the hinge arm body 122, and the lower end of the height adjustment screw 1221 is rotatably disposed on the support base 121. When the height adjustment screw 1221 is rotated to move up and down relative to the support base 121, the gap between the hinge arm body 122 and the support base 121 is increased or decreased, so as to adjust the up and down movement of the hinge in the vertical direction.

[0038] A suspension portion 1211 is provided at the rear end of the support base 121. One end of the suspension portion 1211 is suspended towards the direction of the height adjustment screw 1221, and the other end is connected to the support base 121. Since one end of the suspension portion 1211 is suspended towards the direction of the height adjustment screw 1221, the suspension portion 1211 swings up and down relative to the support base 121 within a certain angle, so that a larger adjustment space is obtained for the support base 121 and the hinge arm 12 in the vertical direction.

[0039] A front-back waist-shaped adjustment hole 12111 is formed in the suspension portion 1211, and a front-back eccentric adjustment member 12112 is rotatably disposed on the hinge arm 12. The lower end of the front-back eccentric adjustment member 12112 is placed in the front-back waist-shaped adjustment hole 12111. When the front-back eccentric adjustment member 12112 is rotated, the lower end of the front-back eccentric adjustment member 12112 will push the hinge arm body 122 to move back and forth relative to the support base 121, so as to achieve the adjustment of the hinge in the front-back direction. Thus, the three-dimensional adjustment of the hinge is realized, and the adjustment operation is simple and convenient.

[0040] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
