Abstract
The utility model relates to an accessory device for a plastic door frame of a folding type refrigerator or a freezer, in particular to a concave-convex mullion which is designed aiming at the technical problems of poorer sealing performance, shorter insulating time and higher energy consumption at the vertical seam of the connection part of the planes between the plastic door mullions of the existing refrigerator (the freezer). The door mullion comprises a left door mullion, a right door mullion, and a stainless steel hinge or a shaft pin, wherein the outer diameters of the left door mullion and the right door mullion are respectively provided with an installing rib and connected with a metal door body by the installing ribs. The left door mullion and the right door mullion are respectively provided with a convex groove and a concave groove which are buckled with each other as well as a hinge groove or shaft pin assembly; and the convex groove and the concave groove are shaped like a cuboid or a long semi-circle body. The door mullion has reasonable design and simple structure, and is applicable to the door frames of various folding type refrigerators (freezers).
Description
Technical field
The utility model relates to the accessories apparatus of collapsible refrigerator or refrigerator-freezer plastic door frame, is a kind of concavo-convex door center.
Background technology
At present, the collapsible refrigerator of selling on the market (refrigerator-freezer) is used in industry-by-industry and family widely, these collapsible refrigerators (refrigerator-freezer) generally are provided with two fan doorframes, and its every fan doorframe is made up of plastic door center, plastic door frame, rubber weather strip, plastic door liner and metal door body.The concrete mounting means of doorframe (or claiming door closure) is: the plastic door center in the doorframe connects the metal door body, and the metal door body connects the plastic door frame again, and the plastic door liner foams; For guaranteeing the sealing effectiveness of door body, refilling weather strip can become complete refrigerator door closure.Wherein, door center (claiming the intermediate door plug again) is the connection that is used between the two fan doorframes, is made up of left-hand door center, right door center, generally based on planar design, connect by stainless hinge or pivot pin assembly, the maximum opening angle of door closure is 180 °, opens door closure drive door center and rotates.The weather strip of two fan doorframes is the sealing functions that are used between doorframe and the casing in the collapsible refrigerator (refrigerator-freezer), but the weather strip below two middle doorframes is the sealing functions that do not have between the two fan doorframes, part weather strip on the door center between the two fan doorframes can't contact the casing of refrigerator (refrigerator-freezer), the left-hand door center is that vertical plane is connected with right door center, no matter which kind of mode of employing connects, the capital produces certain slit, and its slit is generally between 0.5mm～2mm.Simultaneously, deform after foaming as two fan doorframes, its intermediate gap can increase, and the cold air in the casing directly leaks by the slit that two fan doorframe junctions produce, and has greatly reduced sealing performance and heat insulation effect, and energy consumption improves.
Summary of the invention
For overcoming the deficiency of above-mentioned existence, the utility model purpose is to provide a kind of concavo-convex door center that has groove and tongue to this area, make in the middle of its plastics that solve existing refrigerator (refrigerator-freezer) between doorframe junction, plane vertical clearance gap sealing performance relatively poor, temperature retention time is shorter, the energy consumption technical problems of high its objective is to be achieved through the following technical solutions.
A kind of concavo-convex door center, this center is by left-hand door center, right door center, and stainless hinge or pivot pin assembly composition, and the external diameter of left-hand door center, right door center is respectively equipped with the installation muscle, is inserted in plastic door frame or metal door body by muscle is installed.Every fan doorframe of collapsible refrigerator (refrigerator-freezer) is made up of plastic door frame, plastic door center, rubber weather strip, plastic door liner and metal door body, the plastic door center is connected with the metal door body, the metal door body is connected with the plastic door frame, behind the plastic door liner post-foaming, refill weather strip, two fan doorframes are positioned on the casing of refrigerator (refrigerator-freezer) after connecting by hinge or pivot pin.Its design main points are that described left-hand door center, right door center are respectively equipped with tongue and groove, and tongue and groove fasten.When closing left-hand door center or right door center, the left-hand door center fastens with right door center, and the tongue of left-hand door center buckles into the groove of right door center, and the tongue of right door center buckles into the groove of left-hand door center.Said structure makes the left-hand door center after the closure, right door center play box sealing and insulation effect, makes the cold air in the casing be difficult for directly leaking, and cold air leaks comparatively slow by cancavo-convex Curve Path, improved sealing performance, has prolonged temperature retention time.
Described left-hand door center, right door center are respectively equipped with the hinge groove, and hinge is installed on the hinge groove of left-hand door center, right door center respectively.Left-hand door center or right door center are finished rotation between left-hand door center and the right center by hinge; When closing, the groove of left-hand door center fastens with the tongue of right door center, and when opening, the groove of left-hand door center breaks away from the tongue of right door center.
The two ends of described left-hand door center, right door center or be respectively equipped with the pivot pin assembly.The pivot pin at left-hand door center or right door center two ends inserts in the connecting axle pin-and-hole of another right door center or left-hand door center, finishes rotation between left-hand door center and the right center by the connection of pivot pin.
The tongue of described left-hand door center, right door center and groove are cuboid or long semicircular body.According to different body requirements, the tongue and the groove of left-hand door center, right door center can be designed to other corresponding shape.
The utility model is reasonable in design, and is simple in structure, used refrigerator (refrigerator-freezer) good seal performance of this center, and temperature retention time is long, and energy consumption is low, is applicable to the doorframe of various collapsible refrigerators (refrigerator-freezer).
