Description

Technical Field

[0001] The present invention relates to the technical field of pin hinges, and particularly to a groove - free pin hinge. Background Art

[0002] In the fields of furniture manufacturing and decoration, hinges, as key hardware fittings for connecting components such as cabinet doors and drawers to the cabinet body, their performance and installation methods have an important impact on product quality and production efficiency.

[0003] Common pin hinges in the prior art usually need to be installed by embedding in a groove on the cabinet body during installation; this installation method has many drawbacks: on the one hand, groove processing has high process requirements, requires professional equipment and technicians to operate, has a large processing difficulty, and may easily cause damage to the cabinet body during the processing, with a high scrap rate; on the other hand, after grooving, the hinge installation position also needs to be subjected to secondary surface treatment, such as grinding, painting, etc., which not only increases production costs but also prolongs the production cycle, and the overall production efficiency needs to be further improved. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems raised in the above - mentioned background art, and to propose a groove - free pin hinge.

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0033] Embodiment:

[0034] Referring to Figures 1 - 5 , a groove-free pin hinge includes:

[0035] Hinge base 3;

[0036] Hinge body 2, detachably connected to the hinge base 3;

[0037] Hinge cup 1, rotatably connected to the hinge body 2;

[0038] A first installation groove 103 is formed on the hinge cup 1;

[0039] A second installation groove 301 is formed on the hinge base 3;

[0040] A relief groove 101 is formed on the hinge cup 1, and the relief groove 101 matches the hinge body 2;

[0041] The first magnet 201 is fixedly connected to the hinge body 2;

[0042] A placement groove 104 is formed at the bottom of the hinge cup 1;

[0043] The second magnet 1041 is fixedly connected in the placement groove 104, and the first magnet 201 attracts the second magnet 1041;

[0044] When the rotation of the hinge body 2 drives the first magnet 201 to attract the second magnet 1041, the hinge body 2 rotates and is caught in the relief groove 101.

[0045] An inner sliding member 5 is connected to the hinge body 2 through a balance shaft 9. A first adjusting screw 7 is rotatably connected to the hinge body 2, and the first adjusting screw 7 abuts against an adjusting groove on the inner sliding member 5. A second adjusting screw 8 is connected to the hinge seat 3, and the second adjusting screw 8 abuts against an adjusting groove on the hinge body 2.

[0046] A sliding groove 501 is formed on the inner sliding member 5, and the balance shaft 9 is matched with the sliding groove 501.

[0047] A rotating shaft 4 is rotatably connected to the hinge cup 1. The rotating shaft 4 is fixedly connected to the hinge body 2, and wear-resistant sleeves 6 are fixedly connected to both ends of the rotating shaft 4.

[0048] By means of the wear-resistant sleeves 6 provided at both ends of the rotating shaft 4, and the wear-resistant sleeves 6 are located between the hinge body 2 and the hinge cup 1, it can effectively reduce the frictional damage generated when the hinge body 2 and the hinge cup 1 rotate relative to each other.

[0049] A buffer portion 102 is fixedly connected to the hinge cup 1. When the hinge body 2 flips, the driving end of the buffer portion 102 abuts against the hinge body 2.

[0050] It should be noted that the buffer portion 102 is a buffer damper that can be purchased on the market.

[0051] A buffer rubber pad 202 is fixedly connected to the hinge body 2.

[0052] Refer to Figure 1 、 Figure 3 Through the buffer rubber pad 202 fixedly connected to the hinge body 2, when the hinge body 2 rotates and abuts against the hinge cup 1, the buffer rubber pad 202 abuts against the driving end of the buffer portion 102. On the one hand, it can effectively prevent the diameter of the driving end of the buffer portion 102 from abutting against the hinge body 2 and reduce the possibility of the buffer portion 102 scratching the hinge body 2. On the other hand, the buffer rubber pad 202 can effectively reduce the impact noise generated when the hinge body 2 contacts the buffer portion 102 and achieve the effect of silent closing.

[0053] A decorative cover 1031 is detachably connected to the hinge cup 1, and the decorative cover 1031 is located directly above the first installation groove 103.

[0054] Refer to Figure 3 After the hinge cup 1 is fixedly installed using screws, the decorative cover 1031 can be clamped on the hinge cup 1, thereby effectively blocking the screws in the first installation groove 103 and ensuring the overall aesthetics of the hinge.

[0055] During installation and adjustment:

[0056] During installation, there is no need to groove the cabinet body. The hinge seat 3 is directly fixed to the cabinet door with screws, and the hinge cup 1 is fixed to the cabinet body, effectively reducing the rejection rate.

[0057] After installation, when it is necessary to adjust the position of the hinge body 2 in the vertical direction, the first adjusting screw 7 can be rotated. Since the first adjusting screw 7 abuts against the adjusting groove on the inner sliding member 5, and the hinge body 2 is connected to the inner sliding member 5 through the balance shaft 9, and the balance shaft 9 matches the sliding groove 501 on the inner sliding member 5, under the blocking action of the first adjusting screw 7, the inner sliding member 5 will slide back and forth. Also, due to the support and guidance of the balance shaft 9, the hinge body 2 can maintain parallel up and down displacement, thus realizing the adjustment of the hinge body 2 in the up and down direction; when it is necessary to adjust the position of the hinge body 2 in the horizontal direction, the second adjusting screw 8 can be rotated. Since the second adjusting screw 8 abuts against the adjusting groove on the hinge body 2, twisting this screw can make the hinge body 2 achieve front and back displacement, facilitating fine-tuning of the position of the hinge body 2 in the front and back direction to meet different installation and use requirements.

[0058] During the opening and closing process of the cabinet door:

[0059] When the cabinet door is closed, the hinge seat 3 rotates with the cabinet door. The rotation of the hinge seat 3 will drive the hinge body 2 to rotate synchronously. When the hinge seat 3 rotates a certain angle, at this time, the first magnet 201 on the hinge body 2 attracts the second magnet 1041 in the placement groove 104 at the bottom of the hinge cup 1. The hinge body 2 quickly rotates under the magnetic force and snaps into the relief groove 101 of the hinge cup 1 to achieve the preliminary closing of the cabinet door;

[0060] At the same time, during the rotation of the hinge seat 3, the driving end of the buffer portion 102 fixedly connected to the hinge cup 1 will abut against the hinge body 2, and at this time, the rotating hinge body 2 will be buffered and decelerated, finally realizing the silent, slow, and stable closing of the cabinet door.

[0061] When installing this application, there is no need to additionally open installation holes for placing the hinge cup 1 on the cabinet body. Only screws are needed to complete the fixation of the hinge cup 1 and the hinge seat 3. At the same time, the subsequent process of grinding the installation holes is omitted, greatly reducing the installation and processing difficulty, shortening the production cycle, improving the production efficiency, and the installed hinge can cover the surface of the installation position, eliminating the need for secondary surface treatment of the hinge installation position and saving the cost of the post-treatment process.

[0062] 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 and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
