Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a side hidden hinge with an edge binding. Background Art

[0002] Hinge, also known as hinge, is a commonly used metal connector in furniture. In order to improve safety performance and aesthetics, there is a kind of concealed hinge on the market. When the door frame is closed, the hinge will be hidden inside. It is favored by more and more people. However, the current concealed hinge mainly includes a first hinge piece and a second hinge piece connected by a rotating shaft. In order to facilitate installation, the first hinge piece is also provided with a fixing plate. During installation, the second hinge piece is installed together with the first hinge piece on the frame profile, and the fixing plate is installed on the door profile. Then, the first hinge piece is fixedly connected to the fixing plate on the door profile to complete the installation. When the door is closed, the first hinge piece and the fixing plate will be received in the groove of the second hinge piece. However, such a structure is complicated. After the installation is completed, the first hinge piece and the fixing plate are superimposed on each other, which will cause an overall thicker bulge on the surface of the door profile. At the same time, the junction between the first hinge piece and the fixing plate is more obvious and easy to hide dirt, which is not beautiful, and it is difficult to position and install during the connection between the fixing plate and the first hinge piece.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] As shown in the accompanying drawings, the utility model discloses a side hidden hinge with edging, comprising a first hinge piece 1, a second hinge piece 2 and a rotating shaft 3, the first hinge piece 1 comprising a connecting kit 4 and a fixing plate 5, the connecting kit 4 being rotatably connected to the second hinge piece 2 through the rotating shaft 3, a circular tube portion is provided on one side of the connecting kit 4, the rotating shaft 3 is inserted into the circular tube portion, and the two ends are rotatably connected to the second hinge piece 2 respectively, the second hinge piece 2 is also provided with a receiving groove for accommodating the first hinge piece 1 when closing the door, an edging 41 is provided at the edge of the connecting kit 4, thereby forming a receiving space 400 corresponding to the fixing plate 5, an adjusting top screw 44 is threadedly provided on the connecting kit 4, and the adjusting top screw 44 is mainly used to adjust the distance between the fixing plate 5 and the connecting kit 4, because the gap between the fan frames needs to be considered in actual applications, if the gap is too small, it will affect the normal opening of the fan body, so the fixing plate 5 can be moved away from or close to the connecting kit 4 by the adjusting top screw 44, so as to adjust the gap size.

[0019] The utility model discloses a side hidden hinge with edging, which divides a first hinge piece 1 into a connecting kit 4 and a fixing plate 5. When the connecting kit 4 and the fixing plate 5 are combined, the fixing plate 5 is placed in a receiving space 400 provided on the connecting kit 4, so as to reduce the overall thickness of the first hinge piece 1. At the same time, the fixing plate 5 is shielded by the edging 41 to prevent a connecting seam from appearing on the fixing plate 5 and the connecting kit 4, so that the first hinge piece 1 looks more unified, simple and beautiful. Moreover, the receiving space 400 corresponds to the fixing plate 5. During installation, the fixing plate 5 can be directly placed in the receiving space 400, and the position of the fixing plate 5 can be temporarily limited by the edging 41, so as to facilitate installation.

[0020] In this embodiment, the two sides of the back side of the fixing plate 5 are protrudingly provided with abutting edges 52, so that a recessed portion is formed between the two abutting edges 52. When the fan profile is installed, the abutting edges 52 on both sides of the fixing plate 5 abut against the surface of the fan profile, providing multiple installation and connection methods for connecting the fixing plate 5 and the fan profile. For example, the fixing plate 5 and the fan profile can be directly tightened by screws. When the screws are tightened, the fixing plate 5 uses the abutting edges 52 on both sides to contact the profile surface in order to increase the pressure when the screws are tightened. Two grooves corresponding to the abutting edges 52 can also be opened on the surface of the fan profile, and the abutting edges 52 are directly placed in the grooves for preliminary positioning, and then tightened by screws. After the installation is completed, the abutting edges 52 will form a certain locking structure with the fan profile to enhance the connection stability.

[0021] In this embodiment, a connecting hole 500 is provided on the fixing plate 5, and the recessed portion is airtight. The connecting hole 500 is provided with a door leaf mounting screw 303 for fixing the connecting leaf profile. During installation, the fixing plate 5 is first installed to the surface of the leaf profile through the door leaf mounting screw 303. The connecting kit 4 can also be provided with an opening at a position corresponding to the connecting hole 500, so that people can directly screw the door leaf mounting screw 303 without disassembling the connecting kit 4 in the later stage. The opening can also be omitted, thereby reducing the production process, reducing the damage to the connecting kit 4, and making it more beautiful.

[0022] In this embodiment, the thickness of the fixing plate 5 corresponds to the height of the edging 41, that is, the thickness of the fixing plate 5 is set to be less than or equal to the height of the edging 41, and the height of the edging 41 represents the depth of the accommodating space 400, which can ensure that the fixing plate 5 does not protrude from the connecting kit 4 after the installation is completed.

[0023] like Figure 2-3 As shown, the connection kit 4 is provided with frame-leaf connecting screws 101 fixedly connected to the fixing plate 5, and the second hinge piece 2 is provided with door frame mounting screws 202 for connecting the frame profile on both the upper and lower sides. The connection kit 4 and the second hinge piece 2 are both provided with screws for respectively connecting the fixed leaf profile and the frame profile. The front of the connection kit 4 and the second hinge piece 2 are both provided with grooves 600 corresponding to the frame-leaf connecting screws 101 and the door frame mounting screws 202. Cover plates 601 are both provided in the grooves 600. The cover plates 601 are mainly used to shield the internal structure and prevent it from being exposed, so that the hinge as a whole is more simple and beautiful. The cover plates 601 are made of polypropylene material, which has low cost and corrosion resistance, and can better protect the internal structure. The door frame mounting screws 202 and the door leaf mounting screws 303 can also be replaced by fixed connectors such as rivets.

[0024] In this embodiment, the length of the frame-sash connecting screw 101 corresponds to the thickness of the connecting kit 4, and the frame-sash connecting screw 101 is not penetrated through the sash profile. If the frame-sash connecting screw 101 is set too long, the gap between the fixing plate 5 and the sash profile will become larger, or the fixing plate 5 will protrude from the connecting kit 4. Therefore, the length of the frame-sash connecting screw 101 needs to be set according to the thickness of the connecting kit 4 to prevent the fixing plate 5 from protruding from the connecting kit 4, or the gap between the fixing plate 5 and the sash profile is too large.

[0025] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
