Description

Technical Field

[0001] This utility model relates to the field of hinges, and in particular to an electric hinge that is easy to install. Background Technology

[0002] Existing hinges mainly consist of three parts: a first hinge body on each side, a second hinge body, and a connecting pivot. The first and second hinge bodies are rotatably connected to the connecting pivot. However, the existing design requires the first and second hinge bodies to be assembled at the factory before transportation. This design is inconvenient for disassembly and assembly, and it is difficult to adjust according to the position of the connecting holes on the door or door frame.

[0003] For electrically powered hinges, the wiring inside the first hinge body and the second hinge body needs to be connected. If the first hinge cup and the second hinge body are connected in advance, it is not easy to connect the door and the door frame to the first hinge body and the second hinge body respectively during installation. Therefore, an easily installed electrically powered hinge is needed that can reduce the installation difficulty in actual use by designing the connection point. Utility Model Content

[0006] A first connecting sleeve, a second connecting sleeve, and a third connecting sleeve are provided on one side of the first hinge body, and a fourth connecting sleeve and a fifth connecting sleeve are provided on one side of the second hinge body. The fourth connecting sleeve is disposed between the first connecting sleeve and the second connecting sleeve and is connected to the first connecting sleeve through the first connecting shaft. The fifth connecting sleeve can be disposed between the second connecting sleeve and the third connecting sleeve and is connected to the third connecting sleeve through the second connecting shaft.

[0007] The first hinge body and the second hinge body are provided with a first body inner cavity and a second body inner cavity on their inner sides. The fourth connecting sleeve is provided with an annular connecting boss on the side adjacent to the fifth connecting sleeve. The annular connecting boss is provided with a first through hole of the second hinge body that communicates with the inner cavity of the second body.

[0008] The second connecting sleeve has a first through hole on the side adjacent to the first connecting sleeve, which communicates with the inner cavity of the first body. By inserting the annular connecting boss into the first through hole of the first hinge body, the first hinge body is connected to the second hinge body. The wiring in the first connecting cavity and the second connecting cavity is connected by the cooperation of the first through hole of the first hinge body and the first through hole of the second hinge body.

[0009] Preferably, it further includes a first connecting bearing and a second connecting bearing;

[0010] The fourth connecting sleeve and the fifth connecting sleeve are provided with a first connecting groove and a second connecting groove on their outer sides. The first connecting bearing and the second connecting bearing are respectively disposed in the first connecting groove and the second connecting groove of the connecting sleeve, and are disposed on the outer side of the first connecting shaft and the second connecting shaft.

[0011] Preferably, it further includes a first silent bearing and a second silent bearing;

[0012] The first silent bearing is disposed between the first connecting sleeve and the fourth connecting sleeve and sleeved on the outside of the first connecting shaft; the second silent bearing is disposed between the third connecting sleeve and the fifth connecting sleeve and sleeved on the outside of the second connecting shaft.

[0013] By setting the first silent bearing and the second silent bearing, the noise of the first hinge body when rotating relative to the second hinge body can be reduced.

[0014] Preferably, the first connecting shaft and the second connecting shaft are fixedly connected to the first connecting sleeve and the third connecting sleeve by means of threaded connection.

[0015] Preferably, the first hinge body has a plurality of first hinge body connection holes on its side for connection and fixation, and the second hinge body has a plurality of second hinge body connection holes on its side for connection and fixation.

[0016] Preferably, the first hinge body has a second through hole on its side for communicating with the inner cavity of the first hinge body, and the second hinge body has a second through hole on its side for communicating with the inner cavity of the second hinge body.

[0017] Preferably, the connection gap between the fourth connecting sleeve and the fifth connecting sleeve is greater than that between the second connecting sleeve, so that there is enough space for the annular connecting boss to be engaged into the first through hole of the first hinge body.

[0018] The advantages of this easy-to-install electric hinge are as follows:

[0019] 1. By providing a first internal cavity within the first hinge body and a second internal cavity within the second hinge body, the circuits on both sides can be connected through the first internal cavity and the second internal cavity.

[0020] 2. By providing an annular connecting boss on the side of the fourth connecting sleeve adjacent to the fifth connecting sleeve, and providing a first through hole of the first hinge body communicating with the inner cavity of the first body on the side of the second connecting sleeve adjacent to the first connecting sleeve, the second hinge body can be snapped onto the first hinge body by the cooperation of the annular connecting boss and the first through hole of the first hinge body, thus achieving the purpose of pre-connection and facilitating installation.
