Further, two limiting blocks 16 are also arranged, and the two limiting blocks 16 correspond to the pair of limiting grooves 124 one by one, so that the two limiting grooves 124 are uniformly stressed, and the left end and the right end of the hinge 1 are stressed in a balanced manner.

Preferably, each of the limiting grooves 124 penetrates the side plate 112 where the limiting groove is located in the left-right direction, so as to facilitate assembly of the movable shaft 151, improve a contact area between the movable shaft 151 and a groove wall of the limiting groove 124, and improve stability of the movable shaft 151 moving along the limiting groove 124.

Further, the thickness of the limiting block 16 in the left-right direction is greater than the depth of the limiting groove 124 in the left-right direction, so that the stability of the limiting block 16 assembled in the limiting groove 124 is improved, and the limiting block is prevented from falling off in the using process.

Referring to fig. 3 to 4 and fig. 7 to 8, further, the hinge 1 further includes an elastic member 17, the elastic member 17 is located in the assembly space, one end of the elastic member 17 is connected to the movable shaft 151, the elastic member 17 and the movable shaft 151 move synchronously, the other end of the elastic member 17 abuts against the fixed hinge base 11, and when the movable hinge base 12 moves between the door opening position and the initial position, the elastic member 17 is always in a compressed state. Thus, when the movable hinge base 12 rotates around the pivot shaft 113 relative to the fixed hinge base 11, the swing shaft 123 swings along with the movable hinge base and pulls the connecting member 14 to drive the movable shaft 151 to move together, and under the mutual restriction of all the components in the moving process, the swing shaft 123, the movable shaft 151 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 member 14, the movable shaft 151, the elastic member 17 and the fixed hinge base 11 jointly form a crank-slider mechanism, so that the pivoting motion of the movable hinge base 12 is converted into the linear motion of the movable shaft 151 and the elastic member 17, compared with the arc motion of the movable shaft 151 and the elastic member 17, the moving space required by the movement of the elastic member 17 is greatly reduced, especially in the inner and outer directions, and therefore, the thickness of the hinge 1 can be reduced.

In the present embodiment, the elastic member 17 is provided with one; in other embodiments, a plurality of elastic members 17 may be provided to share the stress, and the plurality of elastic members 17 are arranged at intervals, for example, as shown in fig. 12 to 13, two elastic members 17 are provided, and two elastic members 17 are arranged at intervals on two sides of the connecting member 14, so as to share the pressure, thereby making each elastic member small in size and further reducing the thickness of the hinge 1.

In practical application, when the door body 3 is opened to the side edge 122 to abut against the stopper 13 under the action of external force, the door body 3 is opened to the set maximum door opening angle, after the external force is removed, under the action of the gravity of the door body 3, the door body 3 has resilience at a certain angle due to the inevitable fit clearance among the pivot shaft 113, the swing shaft 123 and each part matched and connected with the swing shaft in a rotating manner, so that the side edge 122 is far away from the stopper 13 by a certain distance, and the door body 3 is difficult to hover at the set maximum door opening angle.

To solve the above technical problem, when the movable hinge base 12 is rotated outward relative to the fixed hinge base 11 to the door-opening position, a gap is formed between the movable shaft 151 and the proximal limit end 1241 of the limiting groove 124, and the elastic element 17 has a compression deformation amount. Thus, when the external force is applied to rotate the hinge base 12 to the door opening position along with the door body 3, due to the existence of the gap, the elastic member 17 applies an upward thrust to the connecting member 14 under the action of the elastic restoring force thereof, and transmits the upward thrust to the swinging shaft 123 to form an upward thrust of the connecting member 14 to the swinging shaft 123, so that the hinge base 12 has a tendency of rotating outward around the pivoting shaft 113, and even if the external force is removed, the thrust can form a balance with the gravity of the door body 3, so that the door body 3 hovers at the set maximum door opening angle, and the problem of rebound of the door body 3 after the external force is removed is solved.

In the present embodiment, the elastic member 17 is provided with one; in other embodiments, the elastic member 17 may be provided in plurality according to actual needs. For example, a pair of elastic members 17 are provided at intervals, the pair of elastic members 17 are respectively provided on the left and right sides of the connecting member 14, and the plurality of elastic members 17 can share the force, so that the size of the elastic members 17 can be reduced, and if the elastic members 17 include the springs 172, the outer diameter and the wire diameter of the springs 172 can be reduced, thereby further reducing the thickness of the hinge 1.

Referring to fig. 8, further, the elastic member 17 includes a supporting rod 171 connected to the sliding mechanism 15 and a spring 172 sleeved on the periphery of the supporting rod 171, wherein one end of the supporting rod 171 away from the sliding mechanism 15 is inserted into the fixed hinge base 11 and loosely connected to the fixed hinge base 11, that is, the supporting rod 171 can move up and down relative to the fixed hinge base 11, one end of the supporting rod 171 close to the sliding mechanism 15 is provided with a flange 1711, one end of the spring 172 abuts against the flange 1711, and the other end of the spring 172 abuts against the fixed hinge base 11.

Further, the fixed hinge base 11 includes an end stop 114 disposed at an end thereof far away from the movable hinge base 12, two ends of the end stop 114 are respectively connected with the pair of side plates 112, the end stop 114 has a slot, and an end of the support rod 171 far away from the sliding mechanism 15 is inserted into the slot so as to limit that the elastic member 17 can only move parallel to the bottom plate 111, that is, move up and down, thereby avoiding increasing the thickness of the hinge 1; in this embodiment, the lower end of the spring 172 abuts against the end stop 114, the supporting rod 171 is loosely connected with the end stop 114, and when the elastic member 17 moves up and down synchronously with the movable shaft 151, the lower end of the supporting rod 171 always protrudes out of the end stop 114, so as to prevent the elastic member 17 from falling off the end stop 114 and causing the hinge 1 to fail.

Referring to fig. 4 and 8, further, the hinge 1 further includes a shaft sleeve 18, the shaft sleeve 18 is sleeved on the outer periphery of at least one of the swing shaft 123 and the movable shaft 151, and the shaft sleeve 18 includes a sleeve 181 and an oil storage rib 182 disposed on the inner wall of the sleeve 181, so that lubricating oil can be stored in the sleeve 181 through the oil storage rib 182 in the shaft sleeve 18, and the lubricating oil can slowly seep out from the shaft sleeve 18 to the swing shaft 123 and the movable shaft 151, thereby playing a role in lubricating and protecting the swing shaft 123 and the movable shaft 151, enabling the hinge 1 to smoothly rotate, reducing wear and noise during use, prolonging the service lives of the hinge 1 and the refrigeration equipment 100, and improving user experience.

The sleeve 181 may be cylindrical. Referring to fig. 10 to 11, the cross section of the sleeve 181 is preferably circular arc, and the central angle thereof is 270 to 280 °.
