Description

Technical Field

[0001] This utility model relates to the technical field of hinge components for industrial cabinets, and specifically to a magnetic retaining hinge structure. Background Technology

[0002] Currently available hinges typically consist of two hinge plates connecting the cabinet panel and the cabinet door respectively, and a hinge shaft. The hinge shaft hinges the two hinge plates together, allowing them to swing and open / close the cabinet door. However, existing hinges are generally designed for hinged operation only. After the cabinet door is closed, a radial lock or bolt is needed to lock it in place and prevent it from automatically opening. Even after locking, a very small gap still exists between the door and the cabinet. During operation, the device is inevitably subjected to its own vibration, external vibration, and even wind pressure, causing relative swaying and shaking on the cabinet panel between the two hinge plates. Many cabinet doors, especially those that have experienced increased gaps due to external forces or have been used for a period of time, are prone to generating noise due to this shaking. The shaking between the cabinet panels also increases wear and tear, and the shaking causes internal airflow, making it easier for dust to enter the gaps. Utility Model Content

[0003] The purpose of this invention is to provide a hinge assembly with magnetic holding force, which allows the two hinge pieces to be restricted from relative swinging with a small force when they are in the closed state, thereby keeping the connected plate in a stable closed state.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a magnetic retaining hinge structure, including a first page, a second page, and a rotating shaft. Both the first page and the second page are provided with a sheet body and a rotating sleeve, and are hinged relative to each other by a rotating shaft that passes through both. The first page is also provided with a clearance groove, which is opposite to the second page, and the clearance groove is also provided with a magnetic groove. A magnet is fixed in the magnetic groove, and the magnet is attracted to the sheet body of the second page as it is flipped.

[0005] As a further provision of the above scheme, there are two rotating shafts, and the front ends of the two rotating shafts extend from the outside of the first page, pass through the rotating sleeve on the first page, and are inserted into the rotating sleeve of the second page.

[0006] As a further feature of the above scheme, the rotating shaft is also provided with a radial annular groove with an arc-shaped groove bottom, and the first leaf is provided with a round-headed pin facing the radial annular groove.

[0007] As a further feature of the above scheme, mounting holes one and two are respectively provided on the first and second blades, which are used for bolt fixing to the cabinet plate.

[0008] As a further feature of the above scheme, the rotating sleeve of the second page is provided with a notch groove in the middle. The notch groove is located at the joint between the two rotating shafts, and the maximum length of the two rotating shafts is less than the length of the rotating sleeve on the first page and the second page.

[0009] Beneficial effects: The hinge structure of this utility model has magnetic structures on two hinge plates. Multiple hinges are often installed on a single door. When multiple strong magnets abut against each other on the hinge plate, they form a magnetic attraction that keeps the hinge plates in place without external force. This keeps the hinge side of the cabinet door stable and prevents shaking. Combined with the lock on the other side, the cabinet door remains stationary, reducing the problems of shaking, wear, or noise between the cabinet door and the cabinet body.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0016] like Figure 1-4 The magnetic retaining hinge structure shown includes a first hinge 1, a second hinge 2, and a pivot 4. Both the first hinge 1 and the second hinge 2 are provided with a sheet body 28 and a rotating sleeve 27, and are hinged to each other by the pivot 4 that passes through both. The first hinge 1 is also provided with a relief groove 13, which is opposite to the second hinge 2, and the relief groove 13 is also provided with a magnetic groove 12. A magnet 3 is fixed in the magnetic groove 12, and the magnet 3 is attracted to the sheet body 28 of the second hinge 2 when it is flipped.

[0017] As described above, the hinge of this invention forms a hinged swing structure between leaf 1 and leaf 2 via a pivot 4. Screw holes are provided on leaf 1 and leaf 2 for connection and fixation to the cabinet panel. It is worth noting that... Figure 1 As shown, after the hinge swings, the second hinge piece 2 can match the relief groove 13 and fit into the relief groove 13 of the first hinge piece 1. It is worth noting that, as Figure 2 A magnetic groove 12 is provided in the clearance groove 13, and a magnet 3 is also provided in the magnetic groove 12. After the hinge swings and fits together, the hinge pieces are attracted and held. This setting can prevent the cabinet door fixed on it from shaking by attracting the hinge pieces 2 through the magnet 3, thereby avoiding the vibration of the hinge pieces 2 and preventing the vibration impact and friction of the cabinet body, which would generate noise. In addition, the common cabinet door is usually equipped with at least two hinges. The strong magnetic cooperation between multiple hinges can make even heavy cabinet doors remain stable. The existing technology usually uses hinges on the opening and closing side, which is not only complex in structure and often requires breaking the cabinet body for installation, but also increases the component installation and cost. The hinges in this embodiment use magnetic attraction to keep the hinge pieces from rubbing against each other after they are closed, which can reduce the problem of noise generated by the cabinet door under vibration and shaking.

[0018] As a further provision of the above scheme, there are two rotating shafts 4, and the front ends of the two rotating shafts 4 extend from the outside of the first page 1, pass through the rotating sleeve 27 on the first page 1 and are inserted into the rotating sleeve 27 of the second page 2. The rotating shaft 4 is also provided with a radial annular groove 42 with an arc-shaped groove bottom, and the first page 1 is provided with a round-headed pin 41 facing the radial annular groove 42.

[0019] Furthermore, in this embodiment, the installation of page 1 and page 2 is achieved by hinged connection through the rotating shaft 4 and rotating sleeve 27. To facilitate connection and assembly, a radial annular groove 42 is provided on the rotating shaft 4. The front end of the round-headed pin 41, which is threaded and locked on page 1, extends into the radial annular groove 42 to form an axial limit on the rotating shaft 4, thereby completing the assembly. The screw hole of the round-headed pin 41 is controlled to be located on the inner side of the cabinet after installation. This arrangement not only makes the structural components simple and easy to assemble, but also avoids the operation of disassembly without opening the cabinet door.

[0020] As a further feature of the above scheme, mounting holes 11 and 21 are respectively provided on the first page 1 and the second page 2, and the mounting holes 11 and 21 are used for bolt fixing to the cabinet plate.

[0021] As a further feature of the above scheme, the rotating sleeve 27 of the second page 2 is provided with a notch 23 in the middle. The notch 23 is located at the joint between the two rotating shafts 4. The maximum length of the two rotating shafts 4 is less than the length of the rotating sleeve 27 on the first page 1 and the second page 2. The purpose of the notch 23 is that if the rotating shaft 4 is slightly stuck during disassembly, it can be pushed to both sides of the notch 23 with a tool to disengage it.

[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
