In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 4, a refrigerator 100 of the present invention includes a cabinet 1, a door 2, a hinge assembly 3, and an adjustment assembly 4.
The hinge assembly 3 is pivoted with the door body 2 and the box body 1, and the hinge assembly 3 comprises a hinge 31 fixed on the box body 1, a hinge shaft 32 with one end fixed with the door body 2 and the other end rotatably connected with the hinge 31, and a gasket sleeved on the hinge shaft 32 and positioned between the hinge 31 and the door body 2. The hinge 31 is provided with a long installation groove 33 for the hinge shaft 32 to pass through so as to realize the rotary connection between the hinge shaft 32 and the hinge 31.
The adjusting assembly 4 includes a stopper 41 fixed on the hinge 31 and located at one end of the long mounting groove 33, a rotating member 42 mounted on the hinge shaft 32 and rotating with the hinge shaft 32, an elastic member 43 having one end fixed on the hinge 31 and the other end rotatably connected to the hinge shaft 32 so that the outer profile of the rotating member 42 is always in contact with the stopper 41, a first adjusting structure (not shown), and a second adjusting structure (not shown).
When the door body 2 is closed, the hinge shaft 32 is located at one end of the long mounting groove 33 close to the stop block 41, and the position where the outer profile of the rotating member 42 contacts the stop block 41 is a first position 421; when the door body 2 rotates to the maximum angle, the hinge shaft 32 is located at one end of the long mounting groove 33 away from the stop block 41, and the position where the outer profile of the rotating part 42 contacts the stop block 41 is the second position 422; the outer contour of the rotary member 42 also has a third position on the side of the second position facing away from the first position. That is, the first position, the second position, and the third position are sequentially arranged on the outer contour of the rotating member 42.
The first position is a first distance from the hinge axis 32 that is less than the second distance from the hinge axis 32, any one of the first position and the second position is a distance from the hinge axis 32 that is less than the second distance and greater than the first distance, the second distance is less than the third distance from the hinge axis 32, and any one of the second position and the third position is a distance from the hinge axis 32 that is greater than the second distance; the difference between the second distance and the first distance is equal to the length of the mounting elongated slot 33 in the front-rear direction minus the diameter of the hinge shaft 32.
As the door body 2 is opened, the rotating member 42 rotates along with the rotation of the hinge shaft 32, so that the position of the outer contour of the rotating member 42 contacting the stopper 41 is changed from the first position to a position located at one of the first position and the second position, and since the distance from the position is greater than the first distance, the contact between the rotating member 42 and the stopper 41 moves the hinge shaft 32 in the mounting long groove 33 in the direction away from the stopper 41, and the elastic member 43 is deformed to apply a restoring force to the hinge shaft 32 by the elastic member 43, so that the rotating member 42 is restored to the position where the first position contacts the stopper 41, thereby realizing the automatic door closing of the door body 2.
The length of the long mounting groove 33 in the direction close to or away from the stopper 41 minus the diameter of the hinge shaft 32 is the distance that the hinge shaft 32 can move in the long mounting groove 33, so that after the distance from the outer contour of the rotating member 42 to the hinge shaft 32 is equal to the sum of the first distance and the distance that the hinge shaft can move, the hinge shaft 32 cannot move any more, and therefore the rotating member 42 cannot rotate any more, so that the hinge shaft 32 cannot rotate any more, and the door body 2 cannot be opened any more after being opened to the angle, which is the maximum door opening angle. The angle of the rotating member 42 which can rotate is controlled by the movable distance of the hinge shaft 32 in the long mounting groove 33 and the outer contour of the rotating member 42, so that the maximum door opening angle of the door body 2 is controlled, the structure is simple, and the use is convenient. The third position is used to limit the rotation of the rotating member 42 to the second position even if the door 2 is fixed at the maximum door opening angle.

As the door 2 is opened, the rotating member 42 contacts the stopper 41, and the hinge shaft 32 moves backwards in the installation long groove 33, so as to compress the elastic member 43, so that the elastic member 43 applies a forward movement force to the hinge shaft 32, thereby ensuring that the refrigerator 100 can be automatically closed. When the hinge shaft 32 moves backward to the rear side of the long mounting groove 33 away from the stopper 41, the hinge shaft cannot move backward, the rotating member 42 cannot rotate further, so that the hinge shaft 32 cannot rotate, and the door body 2 stays at the door opening angle, which is the maximum door opening angle, and the position where the rotating member 42 contacts the stopper 41 at this time is the second position. When the door body 2 is released, the elastic member 43 applies a forward force to the hinge shaft 32, so that the hinge shaft 32 moves forward, and the rotating member 42 is driven to rotate, so as to drive the hinge shaft 32 to rotate, thereby realizing automatic door closing.
The elastic member 43 includes a connecting end 431 at the front side, a fixing end 433 at the rear side, and an elastic member body 432 between the connecting end 431 and the fixing end 433. The connecting end 431 comprises a lantern ring 4311 sleeved on the hinge shaft 32 and a first connecting rod 4312 connecting the lantern ring 4311 and the elastic piece body 432; the adjusting assembly 4 further comprises a base 44 fixedly mounted with the hinge 31, a mounting shaft 441 is arranged on the base 44, and a mounting hole fixedly mounted with the mounting shaft 441 is formed in the fixed end 433; the elastic piece body 432 is a spring, and the structure is simple and reliable.
The first adjusting structure adjusts the length of the long mounting groove 33 in the direction approaching or departing from the stop 41, and changes the distance that the hinge shaft 32 can move in the long mounting groove 33, so as to change the second position, and change the maximum door opening angle of the door body 2. The first adjusting structure comprises an adjusting piece mounted at one end of the mounting long groove 33 and a mounting structure for fixing the adjusting piece at any position of the mounting long groove in the length direction of the mounting long groove 33, and the mounting structure has a loosening state for loosening the adjusting piece to enable the adjusting piece to move in the length direction of the mounting long groove and a fixing state for fixing the adjusting piece in the mounting long groove.
The second adjusting structure adjusts an included angle between the first position and the second position to change the maximum door opening angle of the door body. The second is adjusted the structure and is included that a plurality of replacements rotate the piece, will rotate the piece and replace and rotate the piece with hinge pin 32 demountable installation's fixed knot constructs, and is a plurality of the replacement rotates the piece and has different outline so that a plurality of after the installation is accomplished to the replacement rotation piece the primary importance with different contained angles have between the second place. The first position and the second position with different included angles are obtained by using the replacing rotating piece with different outer profiles so as to adjust the maximum door opening angle of the door body.
