Description

Technical Field

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

[0002] The existing hinge includes a base plate and a connecting frame, and a plug-in structure is provided between the base plate and the connecting frame. The front end and the rear end of the base plate are fixedly connected to the connecting frame by elastic fasteners respectively. When the base plate and the connecting frame are assembled, the base plate is first installed on the inner side of the cabinet side panel, and the connecting frame is connected with the inner side of the door panel through a hinge cup. After the cabinet is assembled, the door panel drives the connecting frame to be buckled into the base plate. This assembly is convenient for installation after shipment and saves installation time. However, because it is often impossible to see whether the plug-in structure between the connecting frame and the base plate is aligned, no matter whether the base plate and the connecting frame are fixed at the front end or the rear end first, if the plug-in structure between the connecting frame and the base plate is misaligned, the assembler cannot complete the assembly with the base plate when pressing the hinge hard (the connecting frame cannot be pressed into the base plate).

[0003] The above-mentioned hinge base plate and connecting frame structure can refer to the gapless adjustment structure of a furniture hinge disclosed in Chinese Patent No. ZL202010043628.5. Summary of the invention

[0004] The object of the present invention is to provide a hinge base plate installation mechanism, wherein a first positioning fitting and / or a second positioning fitting for preventing misalignment of the connection between the base plate and the connecting frame is provided between the base plate and the connecting frame; when the connecting frame is pressed and assembled onto the base plate, the guide connecting fittings between the base plate and the connecting frame are in a corresponding state, so that the connecting frame can be accurately pressed and assembled onto the base plate.

[0005] The object of the present invention is achieved in that: A hinge base plate installation mechanism comprises a connecting frame connected to the base plate, a guiding connecting fitting, and a first positioning fitting and / or a second positioning fitting for preventing misalignment of the connection between the base plate and the connecting frame are provided between the base plate and the connecting frame; when the base plate is connected to the connecting frame, the connecting frame is positioned on the base plate by the first positioning fitting or the second positioning fitting, and the guiding connecting fittings between the base plate and the connecting frame correspond to each other, and the base plate and the connecting frame are guided and positioned by the guiding connecting fitting.

[0006] The first positioning fitting includes a positioning groove portion provided on the connecting frame, and the connecting frame is positioned on the bottom plate through the positioning groove portion. When the connecting frame and the bottom plate are fixed at the front end in an inclined manner, the positioning groove portion is locked and positioned on the bottom plate, and the assembler will not make the connecting frame go over the bottom plate even if he assembles with force, that is, the guiding connecting fittings of the bottom plate and the connecting frame are just in an aligned state, and then the connecting frame is pressed to assemble the connecting frame to the bottom plate, and the guiding connecting fitting plays a guiding role, so that the connecting frame is connected to the rear end of the bottom plate, thereby completing the assembly of the connecting frame and the bottom plate.

[0007] The first positioning matching piece is provided with a first guide portion, and the bottom plate and the connecting frame are connected by the first guide portion for positioning and guiding. The first guide portion is an arc surface, and when the connecting frame is pressed onto the bottom plate, the first guide portion plays a role of smooth guidance.

[0008] The second positioning fitting comprises a positioning protrusion arranged on the bottom plate, and one end of the guide connection fitting matches with the positioning protrusion so that the bottom plate and the connection frame are positioned with each other when connected.

[0009] When the connecting frame and the base plate are fixed at the rear end in an inclined manner, when the user pulls the connecting frame and presses it to be assembled on the base plate, the guiding connecting fitting will not go over the positioning protrusion, that is, the guiding connecting fittings of the base plate and the connecting frame are just in an aligned state, and then the connecting frame is pressed to be assembled to the base plate, and the guiding connecting fitting plays a guiding role, so that the connecting frame is connected to the front end of the base plate, thereby completing the assembly of the connecting frame and the base plate.

[0010] The guide connection fitting comprises a connection part arranged on the connection frame, and a second guide part is arranged on the connection part. When the guide connection fitting between the bottom plate and the connection frame corresponds to each other, the connection part of the connection frame is connected with the bottom plate for guiding and positioning along the second guide part. The second guide part is a guide slope, and in the process of pressing the connection frame to be assembled to the bottom plate, the second guide part plays a role in smooth insertion.

[0011] The bottom plate is provided with an installation and covering guide part. When the guide connection matching parts between the bottom plate and the connecting frame part correspond to each other, the connecting frame part is installed and covered on the corresponding position of the bottom plate through the covering guide part.

[0012] The covering guide part is in the shape of an arc. The smooth arc shape can prevent the hinge base plate from scratching the assembler. The arc-shaped covering guide part can also play a guiding role when the connecting frame is pressed and assembled onto the base plate. The connection frame is provided with a limiting cavity for installing and covering the bottom plate portion. When the bottom plate is connected to the connection frame, the bottom plate portion is limited on the limiting cavity.

[0013] The bottom plate is provided with reinforcing ribs for increasing the mechanical strength of the bottom plate, and the reinforcing ribs are convexly arranged on the bottom plate, thereby improving the mechanical strength of the bottom plate and making the bottom plate less likely to be deformed by force.

[0014] A first elastic connecting buckle is provided at one end of the bottom plate and the connecting frame, and a second elastic connecting buckle is provided at the other end of the bottom plate and the connecting frame. The ends between the bottom plate and the connecting frame are connected by the first elastic connecting buckle and / or the second elastic connecting buckle.

[0015] The bottom plate is in a straight line shape; or, a fixing portion for fixing is provided on the bottom plate.

[0016] The beneficial effects of the present invention are as follows: A first positioning fitting and / or a second positioning fitting is provided between the plate and the connecting frame to prevent misalignment of the connection between the base plate and the connecting frame. When the connecting frame is pressed and assembled onto the base plate, the guiding connecting fittings between the base plate and the connecting frame are in a corresponding state, so that the connecting frame can be accurately pressed and assembled onto the base plate, thereby preventing the guiding connecting fittings between the base plate and the connecting frame from being misaligned when the assembler uses excessive force to assemble, thereby preventing difficulty in pressing the connecting frame onto the base plate.
