Description

Technical Field

[0001] The invention relates to the technical field of doors and windows, and in particular to hinges used for opening and closing doors and windows. Background Art

[0002] Existing windows are usually connected by hinges arranged between the window body and the window frame. The hinges include a window frame connector fixedly connected to the window frame and a window connector fixedly connected to the window body. The window frame connector and the window connector are connected by a planar linkage mechanism, such as a planar four-bar mechanism, a connecting rod slider mechanism, etc. In order to ensure the sealing of the planar linkage mechanism of the existing hinge, the planar linkage mechanism is made very compact. When closing the window, especially when the window is closed close to the window frame, the window closing resistance is large, making the window closing process not smooth. Summary of the invention

[0003] In order to solve the above problems, the present invention aims to provide a locking structure to improve the smoothness of the window closing process.

[0004] To achieve the above object, the present invention is implemented according to the following technical solutions:

[0006] A hinge comprises a window frame connecting piece for fixedly connecting to a window frame and a window connecting piece for fixedly connecting to a window body, and comprises the above-mentioned locking structure.

[0007] Preferably, the planar linkage mechanism comprises a planar four-bar mechanism connected to the window connecting member, and the abutment structure is used for fixed connection with the window.

[0008] Preferably, the abutment structure is arranged on the window connecting piece.

[0009] Preferably, the window connecting member is configured as a stamped plate member, and the abutting structure is configured as a stamped flange.

[0011] Preferably, an abutment recess is provided on the outer side surface of the second connecting rod segment, and the bottom wall surface of the abutment recess is used to abut against the first abutment body.

[0012] Preferably, the width of the abutment recess gradually increases in an outward direction.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The abutment structure can be driven by the window body, and the force of closing the window can be dispersed to the abutment structure. The abutment structure moves along the moving path to the abutment planar linkage mechanism, driving the planar linkage mechanism to lock. The force of closing the window can better act on the planar linkage mechanism, so that the planar linkage mechanism can be better locked synchronously with the window body, thereby improving the smoothness of the window closing process while ensuring the compactness of the planar linkage mechanism. At the same time, the abutment structure can be used to cover the side of the planar linkage mechanism, thereby improving the sealing of the planar linkage mechanism.

[0026] Example 1

[0027] like Figures 1 to 3 As shown, this is an embodiment of the present invention, specifically: a hinge, including a window frame connecting member 1 for fixedly connecting to a window frame, a window connecting member 2 for fixedly connecting to a window body, including the above-mentioned locking structure.

[0028] As a further preferred embodiment, the planar linkage mechanism includes a planar four-bar mechanism connected to the window connector 2, and the abutment structure is used to be fixedly connected to the window, that is, the abutment structure is set to a fixed shape to improve the connection reliability of the abutment structure. It has been found through research that for the planar four-bar mechanism, when the window is closed close to the window frame, the rod connected to the window connector 1 is subjected to almost zero force in the width direction, that is, the locking direction. At this time, the abutment structure makes the locking effect of the planar four-bar mechanism better.

[0029] Further as a preferred embodiment, the abutment structure is provided on the window connector 2, so as to facilitate manufacturing together with the window connector 2 and improve the overall manufacturing efficiency.

[0030] As a further preferred embodiment, the window connecting member 2 is configured as a stamped plate, and the abutting structure is configured as a stamped flange.

[0032] As a further preferred embodiment, an abutment recess 221 is provided on the outer side of the second connecting rod section 22, and the bottom wall of the abutment recess 221 is used to abut against the first abutment body 31. The abutment recess 221 makes the hinge more compact after being locked, improves space utilization, and improves the sealing effect between the window body and the window frame.

[0033] As a further preferred embodiment, the width of the abutting recess 221 gradually increases in the outward direction, so that the first abutting body 31 can enter the abutting recess 221 more easily.
