Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a novel hinge that does not require a door catch. Background Technology

[0002] A hinge, also known as a hinge body, consists of hinge bases and hinge bodies that are hinged together. The two hinge bases are equipped with a pivot, and the hinge body is rotatably connected to the pivot. The hinge base is connected to the door frame, and the hinge body is connected to the door leaf. To prevent the door leaf from hitting the wall when it is opened, a door stop is usually also included. However, the installation of door stop can easily damage the wall or floor, and the door leaf will make noise when it hits the door stop when it is opened. Therefore, a type of hinge that does not require a door stop has appeared on the market.

[0003] For example, patent CN209959002U discloses a hinge shaft for a security door that replaces a limiter and limits the opening angle. It includes a hinge shaft body, a hinge shaft sleeve fitted on the circumferential surface of the hinge shaft body, a spring groove on the top of the circumferential surface of the hinge shaft body, a spring installed in the spring groove, a steel ball connected to the side of the spring near the opening of the spring groove, and a set screw connected to the end of the spring away from the steel ball. The set screw is threaded to the inner wall of the hinge shaft body, passes through the inner wall of the hinge shaft body and extends into the spring groove to connect with the spring.

[0004] The problem with the above technology is that when the steel ball is inserted into the groove with multiple opening angles, it will pause. When the security door is opened at a small angle, it will prevent noise caused by wind or excessive force colliding with the wall. However, the steel ball will also make a sound when it is inserted into the groove, and users will experience a sense of jerkiness when opening or closing the door.

[0005] To address this issue, a novel door catch-free hinge is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a novel hinge that does not require a door catch, and which opens the door without any jerking or noise.

[0007] The technical solution adopted by this utility model to solve the problem is: a novel hinge without door catch, including a hinge base and a hinge body. The hinge base is provided with a shaft core, and the hinge body is provided with a bushing. The bushing is sleeved on the shaft core. A spring groove is provided inside the shaft core, and a compression spring is provided inside the spring groove. A limiting ball is connected to the end of the compression spring. An arc-shaped groove is provided on the inner side of the bushing, and the limiting ball extends out of the spring groove and is located inside the arc-shaped groove.

[0008] As a further improvement to the above technical solution, the end of the arc-shaped groove is provided with a limiting groove that is adapted to the limiting ball.

[0009] As a further improvement to the above technical solution, the other end of the compression spring is connected to an adjusting screw, and the spring groove is provided with a through hole connected to the outside, the through hole being located next to the adjusting screw.

[0010] As a further improvement to the above technical solution, the hinge seat is provided with a through groove, the shaft core is inserted into the through groove, the hinge seat is provided with a threaded hole communicating with the through groove, and also includes a fastening screw, the fastening screw is screwed into the threaded hole and abuts against the outer wall of the shaft core.

[0011] As a further improvement to the above technical solution, the upper and lower ends of the shaft core are fitted with shaft seats, the outer end of the shaft seat is fitted with a shaft cover, and both the shaft seat and the shaft cover are provided with semi-circular grooves. A spherical groove is formed between the two semi-circular grooves, and a sphere is provided in the spherical groove.

[0012] The beneficial effects of this utility model are: when in use, the hinge seat is connected to the door frame and the hinge body is connected to the door leaf. When the door leaf is opened, the limiting ball can move in the arc groove. The limiting ball can increase the friction and prevent the door leaf from bursting when the user uses too much force to open or close the door leaf. The arc groove can limit the opening angle of the door leaf. There is no need for a door catch, and the door leaf will not produce a sense of jerking or noise when it is opened.

[0026] Reference Figures 1 to 7 A novel hinge without door catch includes a hinge base 1 and a hinge body 2. The hinge base 1 is provided with a core 3, and the hinge body 2 is provided with a bushing 21. The bushing 21 is fitted onto the core 3. The core 3 is provided with a spring groove 31, and the spring groove 31 is provided with a compression spring 32. The end of the compression spring 32 is connected to a limiting ball 33. The inner side of the bushing 21 is provided with an arc-shaped groove 22, and the limiting ball 33 extends out of the spring groove 31 and is located in the arc-shaped groove 22.

[0027] In use, the hinge seat 1 is connected to the door frame, and the hinge body 2 is connected to the door leaf. When the door leaf is opened, the limit ball 33 can move within the arc groove 22. The limit ball 33 can increase the friction and prevent the door leaf from bursting when the user opens or closes the door leaf due to excessive force. There is no need for a door catch, and the door leaf will not produce a jerky feeling or noise when it is opened.

[0028] In a preferred embodiment, the end of the arc-shaped groove 22 is provided with a limiting groove 23 that is adapted to the limiting ball 33. When the limiting ball 33 moves into the limiting groove 23, the user cannot continue to open the door, which can effectively limit the opening angle of the door. When the door is turned again, the force of pushing the door needs to be increased so that the limiting ball 33 is disengaged from the limiting groove 23.

[0029] In a preferred embodiment, the other end of the compression spring 32 is connected to an adjusting screw (not shown in the figure), and the spring groove 31 is provided with a through hole 35 connected to the outside. The through hole 35 is located next to the adjusting screw. The spring force of the compression spring 32 can be adjusted through the adjusting screw, thereby adjusting the friction between the limiting ball 33 and the arc groove 22, thereby controlling the opening resistance of the door leaf and slowing down the opening speed of the door leaf.

[0030] In a preferred embodiment, the hinge seat 1 is provided with a through groove 11, the shaft core 3 is inserted into the through groove 11, the hinge seat 1 is provided with a threaded hole 12 communicating with the through groove 11, and also includes a fastening screw 13. The fastening screw 13 is screwed into the threaded hole 12 and abuts against the outer side wall of the shaft core 3. During installation, the shaft core 3 and the hinge body 2 are relatively fixed by the limiting ball 33. Then the hinge seat 1 is adjusted to a suitable angle, and the fastening screw 13 is tightened so that the fastening screw 13 abuts against the shaft core 3, thereby adjusting the maximum opening angle of the new type of door-tight hinge.

[0031] In a preferred embodiment, both the upper and lower ends of the shaft core 3 are fitted with shaft seats 41, and the outer end of the shaft seat 41 is fitted with a shaft cover 42. Both the shaft seat 41 and the shaft cover 42 are provided with semi-circular grooves 43, and a spherical groove is formed between the two semi-circular grooves 43. A ball 44 is provided in the spherical groove. During installation, the shaft seat 41 and the shaft cover 42 are pressed between the bushing 21 and the shaft core 3. The ball 44 can reduce the friction of rotation, making the hinge body 2 rotate more smoothly and reducing noise.

[0032] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
