Refrigerator door and punched part connecting structure

Abstract

The invention discloses a refrigerator door and punched part connecting structure. The refrigerator door and punched part connecting structure comprises a connecting structure body; the connecting structure body includes a first mounting plate, a second mounting plate and third mounting plates; the third mounting plates are fixed on the peripheral edge of the bottom of the first mounting plate; an edge wrapping plate is mounted in a rectangular groove through a hinge; the edge wrapping plate is positioned in the rectangular groove when being naturally placed; a vacuum sucker is mounted in a semispherical groove; an exhaust end of the vacuum sucker penetrates through a through hole, and extends to the bottom of the first mounting plate; the exhaust end of the vacuum sucker is tightly connected with an air pipe; a sealed container is fixed at the lower parts of the inner walls of the third mounting plates; the air pipe is inserted in the sealed container, and is sealed through sealant; the side surface of the sealed container is tightly connected with a one-way valve; and the one-way valve penetrates through the third mounting plates. Through design of the vacuum sucker, the refrigerator door and punched part connecting structure can use powerful absorbing force in vacuum for tightly absorbing punched parts.

Description

technical field [0001] The invention relates to the technical field of a stamping part connection structure, in particular to a connection structure between a refrigerator door and a stamping part. Background technique [0002] Stamping parts are formed by applying external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation to obtain workpieces (stamping parts) of required shape and size. Stamping and forging belong to plastic processing (or pressure processing) and are collectively called forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel sheets and strips. [0003] The plate of the stamping part needs to be installed in the refrigerator door shell to strengthen the refrigerator door. Generally, the stamping part is fixed inside the refrigerator door shell by screws or screws. This method cannot tightly attach the stamping part to the refrigerator door shell. Screws and screw fastening are ...

AI Technical Summary

Problems solved by technology

[0003] The plate of the stamping part needs to be installed in the refrigerator door shell to strengthen the refrigerator door. Generally, the stamping part is fixed inside the refrigerator door shell by screws or screws. This method cannot tightly attach the stamping part to the refrigerator door shell. Screws and screw fastening are also easy to loosen. The patent publication number is CN 105865135 A, which proposes a refrigerator door shell hemming structure. The structure includes a main panel, and both ends of the main panel are provided with integrally connected

[0004] End panels, both sides of the main panel are provided with integrally connected side panels; the upper and lower ends of the side panels are provided with integrally connected side panels, and the proximal side of the side panel is provided with a first fold connected to the end of the side panels. The end panel is provided with a second bending groove relative to the first bending groove. This kind of structure is simple and cannot solve the problem of fixing the stamping parts. Therefore, the present invention proposes a connection structure between the refrigerator door and the stamping parts. to solve the above problems
