The maximum angle at which the cabinet 2 opens and the door 3 hovers.

Further, the hinge 1 further includes a connecting member 14, a sliding mechanism 15 and an elastic member 17. The connecting member 14 is pivotally connected with the swing shaft 123 to realize the pivotal connection between the connecting member 14 and the movable hinge base 12, and the fixed hinge base 11 has a limited opening. The position slot 124 and the sliding mechanism 15 include a matching portion 152, and the matching portion 152 is engaged in the limiting groove 124 and can move linearly along the limiting groove 124, so that the sliding mechanism 15 can move linearly along the limiting groove 124, The upper end of the connecting member 14 is pivotally connected to the swing shaft 123 , and the lower end of the connecting member 14 is pivotally connected to the sliding mechanism 15 , so that the connecting member 14 is pivotally connected to the swing shaft 123 and the sliding mechanism 15 and drives the sliding mechanism 15 to move along the limiting groove 124 . Linear motion. The elastic piece 17 is located in the assembly space. One end of the elastic piece 17 is connected to the sliding mechanism 15 and moves synchronously with the sliding mechanism 15. The other end of the elastic piece 17 abuts against the fixed hinge base 11, and the movable hinge base 12 is at the door opening position When moving between the initial position and the initial position, the elastic member 17 is always in a compressed state.

In this way, when the movable hinge base 12 rotates relative to the fixed hinge base 11 around the pivot shaft 113, the swing shaft 123 swings accordingly and pulls the connecting piece 14 to drive the sliding mechanism 15 to move together. The shaft 123 and the pivot shaft 113 are always in a parallel state, and the movable hinge base 12, the pivot shaft 113, the swing shaft 123, the connecting piece 14, the sliding mechanism 15, the elastic piece 17 and the fixed hinge base 11 together constitute a crank-slider mechanism, The pivoting motion of the movable hinge base 12 is transformed into the linear motion of the sliding mechanism 15 and the elastic member 17, which greatly reduces the movement space required for the movement of the elastic member 17 compared with the arc movement of the sliding mechanism 15 and the elastic member 17, and When the movable hinge base 12 is in the initial position, the elastic restoring force of the elastic member 17 provides a support force for the connecting member 14 and the swing shaft 123, and the support force is applied to the swing shaft 123 along the tangential component force of the arc groove 13, which can To achieve the effect of opening the door and saving effort.

The sliding mechanism 15 further includes a movable shaft 151, the movable shaft 151 is parallel to the pivot shaft 113, the limiting slot 124 extends along the first direction, that is, extends up and down, and the matching portion 152 can move up and down along the limiting slot 124, so that the The sliding mechanism 15 moves up and down along the extending direction of the limiting groove 124, the upper end of the connecting piece 14 is pivotally connected to the swing shaft 123, and the lower end of the connecting piece 14 is pivotally connected to the movable shaft 151, so that the connecting piece 14 is pivotally connected to the swing shaft 123 and the swing shaft 123.

Further, the arc-shaped groove 13 has a proximal end close to the elastic member 17 and a distal end away from the elastic member 17. When the swing shaft 123 swings to the proximal end, the movable hinge base 12 is at the initial position, and the door body 3 is closed state; when the swing shaft 123 swings to the distal end, the movable hinge base 12 is in the door opening position, and the door body 3 is in the open state. The limiting slot 124 has a limit proximal end 1241 close to the arcuate slot 13 and a limit distal end 1242 away from the arcuate slot 13; when the swing shaft 123 swings to the proximal end, the matching portion 152 moves to the limit distal end 1242; When the shaft 123 swings to the distal end, there is a gap between the matching portion 152 and the extreme proximal end 1241 , and the elastic member 17 has a compressive deformation amount.

In practical applications, when the door body 3 is opened until the swing shaft 123 swings to the far end under the action of external force, the door body 3 is opened to the set maximum opening angle. Under the action, due to the inevitable gap between the pivot shaft 113, the swing shaft 123 and the various components that are rotated and matched with them, the door body 3 will have a certain angle of rebound in order to maintain balance and hover, that is, the door It is difficult for the body 3 to hover at the set maximum opening angle.

When the swinging shaft 123 swings to the distal end, there is a gap between the fitting portion 152 and the extreme proximal end 1241 , and the elastic member 17 has a compressive deformation amount. In this way, an external force is applied to make the movable hinge seat 12 rotate with the door body 3 to In the door opening position, due to the existence of the gap between the matching portion 152 and the extreme proximal end 1241, the elastic member 17 exerts an upward thrust on the connecting member 14 under the action of its elastic restoring force, and transmits it to the swing shaft 123 to form an upward thrust. The force of the connecting piece 14 to drive the swing shaft 123 to move toward the distal end, so that the movable hinge base 12 has a tendency to rotate outward around the pivot shaft 113. Even after the external force is removed, the thrust force can be balanced with the gravity of the door body 3, thereby The door body 3 is suspended at the set maximum opening angle, which solves the problem of the door body 3 rebounding after the external force is removed.

Compared with the prior art, the hinge 1 and the refrigerating apparatus 100 provided with the hinge 1 provided by the present invention have the beneficial effect that the arc-shaped groove 13 is provided to limit the rotation angle of the movable hinge base 12 relative to the fixed hinge base 11, thereby limiting the door. The door opening angle of the body 3 makes the door body 3 hover after opening the door opening angle; the limit block 16 can be detachably assembled in the limit slot 124 or the locking piece 19 can be detachably assembled with the sliding mechanism 15 or the elastic piece 17 And fixed on the fixed hinge base 11, it can prevent the hinge 1 from being damaged when the fixed hinge base 11 is flipped back and forth relative to the movable hinge base 12 during transportation or when the hinge 1 is assembled in the refrigeration equipment 100. Holding the movable hinge base 12 by hand can make the movable hinge base 12 fixedly fit to the door body 3 for easy installation, which greatly improves the installation efficiency and reduces labor costs; the movable hinge base 12 rotates relative to the fixed hinge base 11 around the swing shaft 123 During the movement, the swing shaft 123 swings accordingly and pulls the connecting piece 14 to drive the movable shaft 151 to move together, and during the movement, under the mutual restriction of each component, the swing shaft 123, the movable shaft 151 and the pivot shaft 113 are always in a parallel state , while the movable hinge base 12, the pivot shaft 113, the swing shaft 123, the connecting piece 14, the movable shaft 151, the elastic piece 17 and the fixed hinge base 11 together constitute a crank-slider mechanism, which converts the pivoting motion of the movable hinge base 12 into The linear movement of the elastic member 17, when the movable hinge base 12 is in the initial position, the elastic restoring force of the elastic member 17 provides a supporting force for the connecting member 14 and the swing shaft 123, and the supporting force is along the tangential component of the arc-shaped groove 13. Applying to the swing shaft 123 can achieve the effect of opening the door and save effort; the shaft sleeve 18 is sleeved on the outer circumference of at least one of the swing shaft 123, the pivot shaft 113 and the movable shaft 151, and the oil storage rib disposed on the inner wall of the sleeve 181 182, lubricating oil can be added between the oil storage ribs 182, and the lubricating oil can slowly seep out from the shaft sleeve 18 to the swing shaft 123, the movable shaft 151, and the pivot shaft 113, so as to play a role in correcting the swing shaft 123 and the movable shaft 151. The lubricating protection function of the pivot shaft 113 makes the hinge 1 rotate smoothly, reduces wear and noise during use, and prolongs the service life of the hinge 1 and the refrigeration equipment 100 .
