Abstract
The utility model discloses a middle hinge composed of a hinge shaft and a connecting portion, wherein the hinge shaft is an independent circular shaft, and a scarfing device is arranged at the joint portion of the hinge shaft and the connection portion. The middle hinge greatly increases the strength of the hinge shaft for refrigerators, the shaft does not shift due to effect of a notch, a key and the like, thereby increasing load intensity of refrigerator doors, and further the middle hinge has low cost and is durable.
Description
Technical field
The utility model relates to a kind of middle hinge, especially a kind of middle hinge that is applicable to refrigerator door.
Background technology
Hinge adopts monoblock cast to form always at present, be easy to produce defectives such as pore, sand holes in the hinge axis bottom, and these defectives are difficult to avoid in casting, through experiment, not having the shearing force at hinge hinge axis place in the cast aluminium of defective is about 40 newton, and have defective less than 25 newton, can not satisfy the requirement of refrigerator door load, and this ratio of defects is 60%, the intensity of hinge axis is reduced greatly, hinge is difficult to meet the demands on intensity in the used cast aluminium of refrigerator, can not guarantee the reliability and durability property of refrigerator.
The utility model content
The purpose of this utility model provides a kind of middle hinge, and the density of load that refrigerator door is born increases, and is durable.
For achieving the above object, the utility model adopts following technical scheme: hinge in a kind of, constitute by hinge axis and connecting portion, and it is characterized in that: hinge axis is independent circular shaft, and the position that hinge axis engages with connecting portion is provided with scarfing device.
Described scarfing device is a groove of being located at the hinge axis cylindrical.
Described scarfing device is a boss of being located at the hinge axis cylindrical.
Described scarfing device is for adding key.
Described scarfing device surface is provided with hatching knurling.
Described connecting portion is provided with bolt hole.
Described hinge axis is the steel axle.
Hinge in the utility model, hinge axis is designed to independent axle just, the intensity of refrigerator hinge axle is increased greatly, and increase groove or connections such as boss, key on independent axle just, because the effect of groove or boss, key etc., axle can play yet, the junction of hinge axis and connecting portion is provided with hatching knurling, connect fasteningly, and cost is not high, durable.
Description of drawings
Fig. 1 is the structural representation of middle hinge;
Fig. 2 is the vertical view of middle hinge;
Fig. 3 is the A-A sectional view among Fig. 2;
The specific embodiment
Hinge in the utility model as shown in Figure 1, is made of hinge axis 1 and connecting portion 2.Connecting portion 2 is provided with bolt hole 31,32, and middle hinge is fastenedly connected refrigerator doors and refrigeratory body by bolt hole 31,32.As shown in Figure 2, hinge axis 1 is steel axle independently, as shown in Figure 3, hinge axis 1 is provided with scarfing device with connecting portion 2 joints, this scarfing device is a groove 4 of being located at hinge axis 1 cylindrical, groove 4 surfaces are provided with hatching knurling, and hinge axis 1 arrives integrally formed single-casting with connecting portion 2 and aluminium alloying then.
The utility model is not limited to this a kind of embodiment, the scarfing device that hinge axis 1 engages with connecting portion 2 not only can be made as the groove 4 of being located at hinge axis 1 cylindrical, can also be made as the boss of being located at hinge axis 1 cylindrical, in addition, scarfing device can also be made as and add key.And then hatching knurling being set on the surface of boss or key, last hinge axis 1 and connecting portion 2 and aluminium alloying are to integrally formed single-casting.
The structure of hinge not only can be used refrigerator in the utility model, and extends to the supporting hinges that has separate material axle foundry goods arbitrarily.
