Description

Technical Field

[0001] The utility model relates to the technical field of freezer accessories, in particular to a freezer hinge structure. Background Art

[0002] For traditional freezer hinges, the door body is fixed to the freezer box through the hinge with multiple screws and directly packed into the warehouse. Since the hinge and screws are exposed, the appearance is seriously affected, resulting in a large number of complaints from users after the product is launched on the market. Some even return the machine, seriously affecting the brand cohesion of the refrigerator enterprise.

[0003] In the existing freezer hinge structure, a plastic part structure is often used to reduce costs. Due to the strength problem of the plastic part structure itself, a ribbed structure shown in the figure is often used technically for reinforcement and fixed to the box body and the door body with multiple screws. Considering the cost reduction factor and the hinge being at the back of the freezer, the refrigerator enterprise adopts a cost reduction method and does not add a hinge cover for beautification, thus resulting in serious appearance defects.

[0046] The working principle of the present utility model: The upper and lower cover bodies adopt an open groove structure, and the shapes of the upper and lower cover bodies match the hinge and the freezer box body. The outer surfaces of the upper and lower cover bodies are designed with smooth surfaces to enhance the aesthetic appearance. The lower ends of the upper and lower cover bodies are designed with large arc surfaces to enhance the appearance and reduce materials for cost reduction. Adjustment rib plates are designed on the inner surfaces of the upper and lower cover bodies. The adjustment rib plates mainly adjust the left and right side clearances between the upper and lower cover bodies and the hinge to achieve a tight fit and prevent the upper and lower cover bodies from shaking left and right. The adjustment rib plates are designed with rib inclined surfaces 7 to facilitate workers to quickly assemble the upper and lower cover bodies with less force, improve the assembly efficiency, and reduce the material cost at the same time. The support rib plate 56 mainly adjusts the front clearance between the upper cover body 5 and the hinge to achieve a tight fit, prevent the upper cover body 5 from shaking up and down, and prevent the upper cover body 5 from deforming inward when the user presses the upper cover body 5 with a finger, affecting the experience. Large inclined surfaces are designed at both ends of the support rib plate 56 to reduce materials and lower the part cost. Two pin shafts are symmetrically designed on the left and right sides of the inner surfaces of the upper and lower cover bodies to improve the connection reliability. The main function of the pin shafts is to position and fix the upper and lower cover bodies. The upper and lower cover bodies adopt pin shafts instead of screws, mainly to enhance the appearance and improve the assembly efficiency. The pin shafts are designed with pin inclined surfaces 8 to facilitate workers to quickly extrude and assemble the upper and lower cover bodies with less force, improve the assembly efficiency, and reduce materials to achieve the purpose of cost reduction. Mounting surfaces and relief grooves are designed on the bottom surfaces of the upper and lower cover bodies. The mounting surfaces mainly support the upper and lower cover bodies and connect them to the freezer box body 1 to prevent the upper and lower cover bodies from deforming when the user presses them, improving the reliability. The relief grooves mainly serve to provide clearance for the freezer opening frame 3 to prevent interference. Relief cuts are designed at the upper end corners of the upper and lower cover bodies, mainly to provide clearance for the hinge limiting structure and for the upper and lower cover bodies.
