Refrigerator top hinge and refrigerator

technical field

The invention relates to the field of refrigerator structure design, in particular to a refrigerator top hinge and a refrigerator equipped with the hinge.

Background technique

The traditional top hinge includes a top hinge and a top hinge reinforcing plate, and more than three screws are used to connect the top hinge and the top hinge reinforcing plate to the side panel of the refrigerator. However, it is more troublesome to install, it takes a long time to assemble three pieces, the operation is troublesome for employees, and the efficiency is low.

Contents of the invention

The technical problem to be solved by the present invention is to provide a refrigerator top hinge capable of quick assembly.

The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a refrigerator top hinge, including a hinge plate, one end of the hinge plate is provided with a refrigerator door shaft seat, the hinge plate is also provided with a clamping hole, the clamping The holes are engaged with the positioning posts provided on the top plate of the refrigerator to clamp the hinge plate on the top plate of the refrigerator.

The beneficial effect of the present invention is: in use, the hinge can be fixed on the top plate by directly clamping the positioning column on the top of the refrigerator through the clamping hole, and the installation speed is fast. According to the applicant's test, the time to install the top hinge of the present application to the top plate is only equal to the time of screwing one bolt, while the hinges in the prior art generally need four bolts to fix. Therefore adopting the top hinge of the present application greatly improves the assembly time.

On the basis of the above technical solutions, the present invention can also be improved as follows.

Further, the clamping hole is a through hole passing through the upper and lower end surfaces of the hinge plate, and there are at least two through holes;

Each of the through holes includes a positioning hole and a limiting hole, and the positioning hole communicates with the limiting hole; there are at least two positioning columns, which are arranged perpendicular to the top plate, and the positioning columns are connected to the positioning columns. The positions of the through holes are in one-to-one correspondence; the positioning hole is sleeved with the upper end of the positioning column and the hinge plate is pushed, so that the positioning column is in the limiting hole, and the positioning column and the limiting hole are clamped. catch.

The beneficial effect of adopting the above further solution is that the positioning column is firstly positioned through the irregular through hole, and then the position is limited, the principle is clear, and the operation is simple and fast.

Further, it also includes a clamping block, the clamping block is arranged on the top plate, and when the positioning column is clamped with the limiting hole, the clamping block is clamped on the side of the hinge plate.

The beneficial effect of adopting the above further solution is that the hinge plate is further fixed by the clamping block, the hinge plate is firmly clamped, and the stability of the hinge is improved after being fixed.

Further, a groove is provided on the lower end surface of the hinge plate along the movement track of the engaging block on the hinge plate.

The beneficial effect of adopting the above-mentioned further solution is that when the positioning column is inserted into the clamping hole, the clamping block is now on the top of the hinge plate and is tightly against the hinge plate, resulting in a slight deformation of the hinge plate . Although this deformation is within the allowable range, when the hinge plate is assembled, the deformation will return to the original flat state under the action of the hinge plate’s own elasticity; but this deformation will increase the friction between the hinge plate and the positioning post . The arrangement of the groove can reduce the amount of deformation of the hinge plate, thereby reducing the friction between the hinge plate and the positioning column, so that the assembly process is more time-saving and labor-saving.

Further, the positioning column includes a column body and a cap head integrally connected, the cap head is fixed on the upper end of the column body and has a cross-sectional area larger than the cross-sectional area of the column body; the area of the positioning hole is larger than that of the cap head Cross-sectional area, the area of the limiting hole is larger than the cross-sectional area of the column and smaller than the cross-sectional area of the hat head; the height of the column is greater than or equal to the thickness of the hinge plate.

The beneficial effect of adopting the above further solution is that the positioning column can be plugged into the clamping hole, and then the right side can be clamped by the limiting hole to realize clamping and fixing.

Further, the shape of the cross section of the limiting hole is adapted to the shape of the cross section of the cylinder. The adaptation mentioned here means that the cylinder can slide in the limiting hole.

The beneficial effect of adopting the above further solution is that the shape is adapted, and the upper end of the positioning post can be easily and easily inserted into the positioning hole.

Further, there is an included angle between the line connecting the center of the positioning hole and the center of the limiting hole included in one of the two through holes and the straight line where the positioning post slides in the positioning hole. .

Further, there are three positioning columns; there are three clamping holes; the centerlines of the three clamping holes form a triangle.

The beneficial effect of adopting the above further solution is that the triangular stable structure will further improve the stability of the assembled structure.

Further, it also includes a pre-embedded iron plate, the pre-embedded iron plate is fixedly installed on the top plate; the clamping block and/or the positioning column is arranged on the top surface of the pre-embedded iron plate.

The technical problem to be solved by the present invention is to provide a refrigerator that can be quickly assembled.

The technical solution of the present invention to solve the above technical problems is as follows: a refrigerator, on the top plate of the refrigerator, a refrigerator top hinge as described in any one of the above technical solutions is installed.

The beneficial effects of the present invention are the same as those of the refrigerator top hinge described above, and will not be repeated here.
