Description

Technical Field

[0001] This utility model relates to the field of pin hinge technology, and in particular to a slot-free pin hinge. Background Technology

[0002] In the furniture manufacturing and decoration industry, hinges, as key hardware accessories connecting cabinet doors, drawers and other components to the cabinet body, have a significant impact on product quality and production efficiency due to their performance and installation methods.

[0003] The common pin hinges in existing technology usually require slotting and embedding in the cabinet during installation. This installation method has many drawbacks: on the one hand, the slotting process has high requirements for craftsmanship, requiring professional equipment and technicians to operate, which is difficult to process and may easily lead to damage to the cabinet during the process, resulting in a high scrap rate; on the other hand, after slotting, secondary surface treatment is required for the hinge mounting position, such as grinding and painting, which not only increases production costs but also extends the production cycle, and the overall production efficiency needs to be further improved.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Example:

[0033] Reference Figures 1-5 A slotless pin hinge, comprising:

[0034] Hinge 3;

[0035] Hinge 2 is detachably connected to hinge seat 3;

[0036] Hinge cup 1 is rotatably connected to hinge body 2;

[0037] The hinge cup 1 has a first mounting groove 103;

[0038] The hinge 3 is provided with a second mounting groove 301;

[0039] The hinge cup 1 is provided with a relief groove 101, which matches the hinge body 2;

[0040] The first magnet 201 is fixedly connected to the hinge 2;

[0041] A placement slot 104 is provided at the bottom of the hinge cup 1;

[0042] The second magnet 1041 is fixedly connected in the placement slot 104, and the first magnet 201 and the second magnet 1041 are attracted to each other;

[0043] When the hinge 2 rotates, causing the first magnet 201 to attract the second magnet 1041, the hinge 2 rotates and gets stuck in the clearance groove 101.

[0044] An inner slide 5 is connected to the hinge body 2 via 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 the adjusting groove on the inner slide 5. A second adjusting screw 8 is connected to the hinge seat 3, and the second adjusting screw 8 abuts against the adjusting groove on the hinge body 2.

[0045] The inner sliding part 5 has a sliding groove 501, and the balance shaft 9 is matched with the sliding groove 501.

[0046] A rotating shaft 4 is rotatably connected to the hinge cup 1. The rotating shaft 4 is fixedly connected to the hinge body 2. Wear-resistant sleeves 6 are fixedly connected to both ends of the rotating shaft 4.

[0047] The wear-resistant sleeves 6 set 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, can effectively reduce the frictional damage generated when the hinge body 2 and the hinge cup 1 rotate relative to each other.

[0048] A buffer part 102 is fixedly connected to the hinge cup 1. When the hinge body 2 is flipped, the driving end of the buffer part 102 abuts against the hinge body 2.

[0049] It should be noted that the buffer section 102 is a commercially available buffer damper.

[0050] A buffer rubber pad 202 is fixedly connected to the hinge 2.

[0051] Reference Figure 1 , Figure 3 By fixing the buffer pad 202 to the hinge body 2, when the hinge body 2 rotates and comes into contact with the hinge cup 1, the buffer pad 202 comes into contact with the driving end of the buffer part 102. On the one hand, it can effectively prevent the diameter of the driving end of the buffer part 102 from hitting the hinge body 2, reducing the possibility of the buffer part 102 scratching the hinge body 2. On the other hand, the buffer pad 202 can effectively reduce the impact noise generated when the hinge body 2 comes into contact with the buffer part 102, achieving the effect of silent closing.

[0052] A decorative cover 1031 is detachably connected to the hinge cup 1, and the decorative cover 1031 is located directly above the first mounting groove 103.

[0053] Reference Figure 3 After the hinge cup 1 is fixedly installed using screws, the decorative cover 1031 can be clipped onto the hinge cup 1, thereby effectively covering the screws in the first mounting groove 103 and ensuring the overall aesthetics of the hinge.

[0054] During installation and adjustment:

[0055] During installation, there is no need to cut grooves in the cabinet. The hinge bracket 3 is directly fixed to the cabinet door with screws, and the hinge cup 1 is fixed to the cabinet body, which effectively reduces the scrap rate.

[0056] After installation, if the vertical position of the hinge 2 needs to be adjusted, the first adjusting screw 7 can be rotated. Since the first adjusting screw 7 abuts against the adjusting groove on the inner slide 5, and the hinge 2 is connected to the inner slide 5 through the balance shaft 9, which matches the sliding groove 501 on the inner slide 5, the inner slide 5 will slide back and forth under the locking action of the first adjusting screw 7. Due to the support and guidance of the balance shaft 9, the hinge 2 can maintain parallel vertical displacement, thereby realizing the vertical adjustment of the hinge 2. When the horizontal position of the hinge 2 needs to be adjusted, the second adjusting screw 8 can be rotated. Since the second adjusting screw 8 abuts against the adjusting groove on the hinge 2, turning the screw can make the hinge 2 move back and forth, making it convenient to fine-tune the position of the hinge 2 in the back and forth direction to meet different installation and use requirements.

[0057] During the opening and closing of the cabinet door:

[0058] 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 to a certain angle, the first magnet 201 on the hinge body 2 and the second magnet 1041 in the bottom placement groove 104 of the hinge cup 1 attract each other. Under the action of magnetic force, the hinge body 2 rotates quickly and gets into the clearance groove 101 of the hinge cup 1, realizing the initial closing of the cabinet door.

[0059] Meanwhile, during the rotation of the hinge seat 3, the drive end of the buffer part 102 fixedly connected to the hinge cup 1 will abut against the hinge body 2, which will buffer and decelerate the rotating hinge body 2, ultimately achieving silent, slow, and smooth closing of the cabinet door.

[0060] During installation, this application eliminates the need to drill additional mounting holes on the cabinet for the hinge cup 1. The hinge cup 1 and hinge seat 3 can be fixed with screws, thus eliminating the need for subsequent grinding of mounting holes. This greatly reduces the difficulty of installation and processing, shortens the production cycle, and improves production efficiency. Furthermore, the installed hinge can cover the surface of the mounting position, eliminating the need for secondary surface treatment of the hinge mounting position and saving the cost of post-processing.

[0061] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
