Description

Technical Field

[0001] The utility model relates to a hinge, in particular to a hinge bottom plate mounting mechanism. Background Art

[0002] The existing hinge includes a bottom plate and a connecting frame member. There is a plug-in structure between the bottom plate and the connecting frame member. The front end and the rear end of the bottom plate are respectively fixedly connected to the connecting frame member through elastic fasteners. When the bottom plate and the connecting frame member are in the assembled part, the bottom plate is first installed on the inner side of the cabinet side plate, and the connecting frame member is connected in cooperation with the inner side of the door panel through a hinge cup. After the cabinet is assembled, the door panel drives the connecting frame member to be buckled into the bottom plate. In this way, the assembly is convenient to install after shipment and saves installation time. However, because it is often impossible to see whether the plug-in structure between the connecting frame member and the bottom plate is aligned, no matter whether the front end or the rear end of the bottom plate and the connecting frame member are fixed first, if the plug-in structure between the connecting frame member and the bottom plate is misaligned, when the assembler presses the hinge forcefully, the connecting frame member cannot be assembled with the bottom plate (the connecting frame member cannot be press-fitted onto the bottom plate).

[0003] For the structures of the above-mentioned hinge bottom plate and the connecting frame member, reference can be made to a gapless adjustment structure of a furniture hinge disclosed in Chinese Patent No. ZL202010043628.5. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hinge bottom plate mounting mechanism. A first positioning and fitting member and / or a second positioning and fitting member for preventing misconnection between the bottom plate and the connecting frame member are arranged between the bottom plate and the connecting frame member. When the connecting frame member is press-fitted onto the bottom plate, the guiding connection and fitting members between the bottom plate and the connecting frame member are in a corresponding state, and the connecting frame member can be accurately press-fitted onto the bottom plate.

[0005] The purpose of the utility model is achieved as follows:

[0006] A hinge bottom plate mounting mechanism includes a connecting frame member connected to the bottom plate. A guiding connection and fitting member, and a first positioning and fitting member and / or a second positioning and fitting member for preventing misconnection between the bottom plate and the connecting frame member are arranged between the bottom plate and the connecting frame member. When the bottom plate is connected to the connecting frame member, the connecting frame member is positioned on the bottom plate through the first positioning and fitting member or the second positioning and fitting member, and the guiding connection and fitting members between the bottom plate and the connecting frame member are corresponding to each other. The bottom plate and the connecting frame member are guidingly positioned and connected through the guiding connection and fitting members.

[0007] The first positioning and mating part includes a positioning groove portion provided on the connecting frame member, and the connecting frame member is positioned on the bottom plate through the positioning groove portion. When the connecting frame member and the bottom plate are fixed at the inclined front end, the positioning groove portion is locked and positioned on the bottom plate. Even if the assembler applies force during assembly, the connecting frame member will not cross over the bottom plate, that is, the guiding connection and mating part between the bottom plate and the connecting frame member is just in the aligned state. Then, by pressing the connecting frame member, the connecting frame member is assembled onto the bottom plate. The guiding connection and mating part plays a guiding role to connect the connecting frame member and the rear end of the bottom plate, thereby completing the assembly of the connecting frame member and the bottom plate.

[0008] The first positioning and mating part is provided with a first guiding portion, and a positioning and guiding connection is made between the bottom plate and the connecting frame member through the first guiding portion. The first guiding portion is in an arc shape, and when the connecting frame member is pressed onto the bottom plate, the first guiding portion plays a smooth guiding role.

[0009] The second positioning and mating part includes a positioning protrusion provided on the bottom plate, and one end of the guiding connection and mating part is mated with the positioning protrusion so that the bottom plate and the connecting frame member are positioned relative to each other during connection.

[0010] When the connecting frame member and the bottom plate are fixed at the inclined rear end, when the user pulls the connecting frame member and presses it onto the bottom plate for assembly, the guiding connection and mating part will not cross over the positioning protrusion either, that is, the guiding connection and mating part between the bottom plate and the connecting frame member is just in the aligned state. Then, by pressing the connecting frame member, the connecting frame member is assembled onto the bottom plate. The guiding connection and mating part plays a guiding role to connect the connecting frame member and the front end of the bottom plate, thereby completing the assembly of the connecting frame member and the bottom plate.

[0011] The guiding connection and mating part includes a connecting portion provided on the connecting frame member. A second guiding portion is provided on the connecting portion. When the guiding connection and mating part between the bottom plate and the connecting frame member corresponds, the connecting portion of the connecting frame member makes a guiding and positioning connection with the bottom plate along the second guiding portion. The second guiding portion is a guiding inclined surface, and during the process of pressing the connecting frame member onto the bottom plate for assembly, the second guiding portion plays a role in smooth insertion.

[0012] An installation and covering guiding portion is provided on the bottom plate. When the guiding connection and mating part between the bottom plate and the connecting frame member corresponds, the connecting frame member is installed and covered on the corresponding position of the bottom plate through the covering guiding portion.

[0013] The covering guiding portion is in an arc shape. The arc shape is relatively smooth, which can prevent the hinge bottom plate from scratching the assembler, and can also play a guiding role when the connecting frame member is pressed onto the bottom plate.

[0014] A limiting cavity portion for installing and covering a part of the bottom plate is provided on the connecting frame member. When the bottom plate and the connecting frame member are connected, a part of the bottom plate is limited on the limiting cavity portion.

[0015] The bottom plate is provided with a reinforcing rib portion for increasing the mechanical strength of the bottom plate, and the reinforcing rib portion protrudes on the bottom plate. This improves the mechanical strength of the bottom plate, making it not easily deformed under force.

[0016] One end of the bottom plate and the connecting frame member are provided with a first elastic connection and fastening portion, and the other end of the bottom plate and the connecting frame member are provided with a second elastic connection and fastening portion. The end between the bottom plate and the connecting frame member is connected through the first elastic connection and fastening portion and / or the second elastic connection and fastening portion.

[0017] The bottom plate is in a straight shape; or, the bottom plate is provided with a fixing portion for fixation.

[0018] The beneficial effects of the present utility model are as follows:

[0019] Between the plate and the connecting frame member, there are a first positioning and fitting member and / or a second positioning and fitting member for preventing misalignment of the connection between the bottom plate and the connecting frame member. When the connecting frame member is press-fitted onto the bottom plate, the guiding connection and fitting members between the bottom plate and the connecting frame member are in a corresponding state, so that the connecting frame member can be accurately press-fitted onto the bottom plate, avoiding the misalignment state of the guiding connection and fitting members between the bottom plate and the connecting frame member when the assembler presses too hard during assembly, and avoiding the difficulty of pressing the connecting frame member onto the bottom plate.
