Description

Technical Field

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

[0002] Pin hinges are furniture hinges with a long, needle-shaped hinge axis. They generally consist of a hinge base and a mounting base. The hinge base has a hinge pin and a copper sleeve. During installation, the copper sleeve is embedded in both sides of the hinge base. Then, the hinge pin passes through the door frame profile, through the hinge base, and through the copper sleeves located on both sides of the hinge base, thus completing the installation of the hinge base on the door frame. However, in the current use of this type of pin hinge, because the copper sleeve is embedded in the hinge base, when the door is opened and closed, the rotation of the hinge base causes friction between the copper sleeve and the door frame, which produces abnormal noise when the door is opened and closed.

[0003] The technical problem to be solved by this application is: to design a silent pin hinge that can eliminate abnormal noise. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a silent pin hinge that can eliminate abnormal noise.

[0005] The technical solution adopted by this utility model is as follows: a silent pin hinge, including a hinge seat and a mounting seat hinged to the hinge seat. The hinge seat is provided with a copper sleeve that is limited and installed therewith. A hinge component for rotatably connecting with the door frame profile is inserted inside the copper sleeve. The hinge component is provided with a gasket that is limited and rotatably engaged with it to prevent friction between the copper sleeve and the door frame profile from generating abnormal noise.

[0006] In some embodiments, the hinge seat has a through hole, and the copper sleeve is installed between the through hole and the limiting device.

[0007] In some embodiments, copper sleeves are disposed on both sides of the hinge seat, and the copper sleeves are mirror-mounted on both sides of the hinge seat.

[0008] In some implementations, the copper sleeve is hollow.

[0009] In some embodiments, a limiting ring is provided at one end of the copper sleeve.

[0010] In some embodiments, the hinge is a spring pin that is limited and slidably engaged with one end of the copper sleeve, and the washer is limited and engaged with the spring pin.

[0011] In some embodiments, the hinge is a hinged long shaft that passes through a through hole and engages with two copper sleeves for a limiting fit.

[0012] In some implementations, the gasket is positioned in a limiting fit with the hinged long shaft.

[0013] This utility model has the following technical effects: By providing a shim that limits the rotation of the hinge, the shim is located between the copper sleeve and the door frame profile. The door frame profile generates friction due to contact with the shim. Therefore, when the door is rotated to open or close, the door frame profile will drive the shim to rotate along the hinge, thereby avoiding abnormal noise caused by friction between the door frame profile and the copper sleeve.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1-3This utility model provides a technical solution: a silent pin hinge, including a hinge base 1 and a mounting base 2 hinged to the hinge base 1. A copper sleeve 3 is provided on the hinge base 1 for limiting its installation. To allow the copper sleeve 3 to be installed on the mounting base 2, a through hole 10 is provided inside the hinge base 1, wherein the copper sleeve 3 is limited and installed between itself and the through hole 10. The copper sleeve 3 is installed on both sides of the hinge base 1, and the copper sleeve 3 is mirror-image installed on both sides of the hinge base 1. Furthermore, the copper sleeve 3 is hollow. Each sleeve 3 is fitted with a hinge for rotatably connecting with the door frame profile 7. To ensure the sleeve 3 can be positioned within the through hole 10, a limiting ring 30 is provided at one end of the sleeve 3. The diameter of the limiting ring 30 is larger than the diameter of the through hole 10, thus allowing the sleeve 3 to be positioned within the through hole 10. A shim 4 is provided on the hinge for limiting rotational engagement, thereby preventing friction and noise between the sleeve 3 and the door frame profile 7. The shim 4 is made of steel, copper, or plastic. In this embodiment, the hinge is a spring pin 5 that has a limiting ring 30 at one end of the copper sleeve 3 for limiting and sliding engagement. The spring pin 5 is embedded in one end of the copper sleeve 3, and one end of the spring pin 5 also protrudes outwards. A spring is provided inside the copper sleeve 3 to support the spring pin 5. Pressing the spring pin 5 compresses it within the copper sleeve 3, and releasing the pressure causes the spring pin 5 to spring back outwards. A washer 4 has a limiting engagement with the protruding end of the spring pin 5. When installing this hinge… The connection between the hinge seat 1 and the door frame profile 7 can be achieved by making the spring pins 5 on the copper sleeves 3 on both sides of the hinge seat 1 and the door frame profile 7 rotate and limit each other. In this way, the gasket 4 on the spring pin 5 is located between the door frame profile 7 and the copper sleeve 3. Friction is generated between the door frame profile 7 and the gasket 4. When the door is rotated to open and close, the door frame profile 7 will drive the gasket 4 to rotate along the spring pin 5, thereby avoiding abnormal noise caused by friction between the door frame profile 7 and the copper sleeve 3, thus achieving a silent effect.

[0022] Example 2: Please refer to Figure 4-5 This utility model provides another technical solution: a silent pin hinge. The difference between this embodiment and Embodiment 1 is that the hinge component in this embodiment is a hinge shaft 6, which is a single piece. The hinge shaft 6 passes through the copper sleeve 3 on one side of the hinge seat 1 and through the copper sleeve 3 on the other side of the hinge seat 1. This is equivalent to the hinge shaft 6 passing through a complete through hole 10 and being fitted between the two copper sleeves 3. A washer 4 is installed at both ends of the hinge shaft 6 and is fitted between the hinge shaft 6 for rotational limitation. When installing the hinge in this embodiment, the hinge seat 1 and the door frame profile 7 are rotatably connected at both ends of the hinge shaft 6. At this time, the washer 4 is also located between the door frame profile 7 and the copper sleeve 3. When the door rotates open and closes, friction between the door frame profile 7 and the washer 4 will also cause the washer 4 to rotate along the hinge shaft 6, thereby avoiding abnormal noise caused by friction between the door frame profile 7 and the copper sleeve 3, thus achieving a silent effect.

[0023] The working principle of this utility model is as follows: A shim 4 is provided on the hinge to limit its rotation. Since the shim 4 is located between the copper sleeve 3 and the door frame profile 7, the door frame profile 7 generates friction due to contact with the shim 4. Therefore, when the door is rotated to open and close, the door frame profile 7 will drive the shim 4 to rotate along the hinge, thereby avoiding abnormal noise caused by friction between the door frame profile 7 and the copper sleeve 3.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
