Embodiment 1

[0021] Such as figure 1 , 2 As shown, the offset hinge mechanism of the present invention includes: a housing 7, an external shaft housing 5, a fixed shaft 1, a connecting piece 3, a sliding plunger 6, and a return spring 9, wherein the sliding plunger 6, the return spring 9 The sequence device is in the housing 7, fixed in the housing 7 by the pressure adjustment screw 10; the housing 7 is provided with a support arm 8 (see figure 1 ), which is used to fixedly connect the device of the present invention to the bottom surface of the door leaf; the outer side of the housing 7 is also provided with a relatively parallel external shaft housing 5, and the fixed shaft 1 is installed in the external shaft housing 5 through a bearing 4 (see figure 2 ); on the plane of the external axle housing 5, there are mounting screw holes 11 which can install the device of the present invention on the side of the bottom of the door leaf (see image 3 ) (this example is a separate external typ...

Embodiment 2

[0023] The connecting piece 3 and the fixed shaft 1 of the present invention can also adopt such as Figure 5 The connection mode shown: a spiral groove corresponding to the spiral groove 2 of the fixed shaft 1 is provided in the shaft hole of the connector 3, and the meshing steel ball 13 is embedded in the spiral groove to form a rolling spiral friction pair.

Embodiment 3

[0025] Such as Figure 6 As shown, one end of the connector 3 is provided with a rolling bush 15, and the fixed shaft 1 is provided with a helical surface 14, and the rolling bush 15 and the helical surface 14 constitute a rolling helical friction pair.

Abstract

The invention provides an offset hinge mechanism which comprises a shell, a fixed shaft, a sliding plunger and a return spring, wherein the sliding plunger, the return spring and a pressure adjusting screw are sequentially arranged in the shell. The invention is characterized in that an external shaft housing is arranged outside the shell, and the fixed shaft is installed in the external shaft housing; and one end of a connecting piece is articulated with the fixed shaft, and the other end of the connecting piece is connected with the sliding plunger. The external shaft housing is additionally arranged outside the shell of the hinge mechanism of the invention, and a parallel arrangement mechanism is formed by the fixed shaft and the sliding plunger through the connecting piece, thereby realizing the purpose of offsetting the fixed shaft and the shaft center of the shell. The whole shell is hidden and installed in the vertical frame of a door leaf, very long rod pieces are not supported outside, and the appearance is not provided with installing screws. The offset hinge mechanism has the advantages of simple structure, safety, durability and beautiful appearance, embodies unexampled advancement as compared with the prior art, and has wide market prospect and social benefit.

Description

technical field [0001] The invention provides an offset hinge mechanism, which is an improvement on the existing hinge door closer structure, and belongs to the technical field of door and window hardware. Background technique [0002] So-called hinged door closers have a housing in which a piston is linearly displaceable. For automatic closing of the door leaf, a mechanical energy store formed by the closer spring acts on a drive element formed by the closer shaft, to which a linkage is connected. When in use, the shell is installed on the upper end of the door leaf surface with screws, and the outer support of the long rod linkage mechanism is installed on the door frame. Sometimes the rods fall off, and the door panel is pulled off and damaged, causing accidents and unnecessary losses. Very detrimental to appearance. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects existing in the prior art, and provide...
