Description

Refrigerators hinge and refrigerator

Technical field

The utility model relates to a kind of hinge means, is specifically related to a kind of refrigerator hinge; The utility model further relates to a kind of refrigerator that is provided with this hinge.

Background technology

Refrigerator can be used for refrigeration or frozen food, has greatly made things convenient for the people's life.Refrigerator door is when opening, open excessive for preventing a body, the door body collides object on every side or causes the loss of cold, a body is set on the refrigerator usually opens stop device, this stop device can make refrigerator door stop after opening certain angle, prevent that the refrigerator door unlatching is excessive, the refrigerator door stop device is arranged on the Refrigerator door hinge usually, because hinge itself is refrigerator door folding parts, the refrigerator door stop device is arranged on is convenient to refrigerator door on the refrigerator hinge and opens control, simplify stop configurations, as the disclosed refrigerator doors hinge means of Chinese patent CN2127989, it comprises the following hinge seat (3) that is fixed on the casing (1), is fixed with hinge axis (4) in the above, a, the dome (9) that one section circular arc is arranged on the following hinge seat (3) has a backstop (13) at the end of dome (9); B, on chamber door (2) bottom surface and the corresponding position of following hinge seat (3), be fixed with door holder retaining (7), one " L " shape flange (16) is arranged in the above, have one and the stop surface (15) that matches of backstop (13) contact surface on the flange (16); C, on casing (1), also be fixed with the locking segment (12) that has " V " shape groove (11), have the structure of the locking slide block (6) of dead bolt (5) in chamber door (2) bottom surface and the corresponding fixed-site one of locking segment (12).

Existing a kind of Refrigerator door hinge, hinge comprises upper flap and lower flap, upper flap is arranged on the refrigerator door, lower flap is arranged on the refrigerator body, rotating shaft is set on the lower flap, be provided with on the upper flap and be sleeved on rotating axle sleeve in the rotating shaft, commentaries on classics is connected upper flap with the lower flap axle, upper flap is set on the upper flap opens the back stop surface, extend the stop block after projection is bent to form the upper flap unlatching on the lower flap, stop block includes the lateral surface that the lower flap soffit extends, the medial surface that the lower flap upper surface extends, the left side, right side and upper surface, the stop surface of lower flap are the left side near the lower flap projection of upper flap stop surface.The shortcoming that the refrigerator hinge of this structure exists is: because the metal sheet of processing refrigerator hinge is thinner, therefore the backstop area of the stop surface that is formed by the left side of lower flap is little, when the door body is opened, refrigerator door backstop instability, cause refrigerator door to rock easily, make troubles for the refrigerator user; Further, because refrigerator door is opened backstop the angle requirement is arranged, the stop angle that is refrigerator door can not be excessive and too small, and to realize the control of refrigerator door opening angle, with regard to requiring the angle of stop surface is carried out machining control,, make the left side of ledge form stop surface and carry out angle control because refrigerator hinge lower flap stop surface forms by the ledge bending back that is arranged on the lower flap, processing technology is required height, complex technical process.

Summary of the invention

The utility model provides a kind of refrigerator hinge of architecture advances, and this refrigerator hinge is stable to refrigerator door backstop, and is easy to use.

The utility model provides a kind of refrigerator hinge separately, and this refrigerator hinge processing technology is simple.

For realizing the goal of the invention of the utility model Refrigerators hinge and refrigerator, the utility model has adopted following technical proposals.

The utility model discloses a kind of refrigerator hinge, described hinge comprises upper flap and lower flap, described upper flap is connected with described lower flap axle commentaries on classics, upper flap is set on the described upper flap opens the back stop surface, extend the stop block after projection is bent to form the upper flap unlatching on the described lower flap, described stop block comprises the lateral surface that is extended by the lower flap soffit, medial surface, left and right sides end face and the upper surface that the lower flap upper surface extends, and it is characterized in that

The stop surface of described lower flap is the lateral surface of described stop block.

The utility model further discloses a kind of refrigerator, comprise refrigerator body, the front portion of refrigerator body is provided with a body, hinge is set on the refrigerator door, described hinge comprises the upper flap that is fixed on the refrigerator door and is fixed on the lower flap of refrigerator body, described upper flap is connected with described lower flap axle commentaries on classics, stop surface after upper flap is opened is set on the described upper flap, extend the stop block after projection is bent to form the upper flap unlatching on the described lower flap, described stop block includes the lateral surface that the lower flap soffit extends, the medial surface that the lower flap upper surface extends, left and right sides end face and upper surface, it is characterized in that

In the technique scheme, the stop surface of lower flap adopts described stop block lateral surface, the stop surface of the lower flap that is extended to form by the bottom surface projection of lower flap can carry out control corresponding as required in the hinge process, therefore obtain the door body bigger and open stop surface than original projection face area, more stable when the door body is opened backstop, use more convenient.

Further directly adopt the stop surface that bends the lower flap that extends to form by the bottom surface projection of lower flap, can process the lower flap stop surface easily, made things convenient for the control of lower flap stop surface machining angle, simplified processing technology.

For prevent a body excessively open collision around the refrigerator other objects and prevent that cold runs off, described upper flap opening angle and described hinge closing direction are greater than 180 °.

Further for the refrigerator door opening angle is controlled, preferred: described upper flap stop surface is vertical with described hinge closing direction, and the lateral surface of described stop block and closing direction described hinge are greater than 180 °.

For making refrigerator door close back refrigerator door tight close, on the described lower flap reference column is set, hook was contained in the location hook on the reference column when hinge closure was set on the described upper flap.Therefore upper flap processes by elastoplast, even if after refrigerator door is closed, the location hook hook is contained on the reference column on the lower flap on the upper flap, when opening refrigerator door, by applying certain pulling force, location hook and reference column are broken away from, can open refrigerator door easily.

The preferred axle rotation structure of going up lower flap is: on the described lower flap rotating shaft is set, is provided with on the described upper flap and is sleeved on rotating axle sleeve in the rotating shaft.

In the utility model, by improving the stop configurations of refrigerator lower flap, promptly adopt the stop surface of the extended stop block lateral surface in lower flap bottom surface as lower flap, backstop was stable when refrigerator door was opened, easy to use, and further simplified the processing technology of refrigerator hinge, improved efficiency.
