[0026] The connecting assembly 4 comprises a pair of symmetrical stand ears 41 arranged on one side of the box top cover 11, and box shaft holes 42 are arranged in the middle of the two stand ears 41. The stand ear 41 is a part of the box top cover 11, and provides a connecting point. The box shaft hole 42 is used to install the damping shaft 43 when connecting the box assembly 1 and the door body assembly 2, so as to realize the rotation and damping effect of the door body. A pair of cylinders 44 are symmetrically arranged on the bottom of the door body upper shell 22 corresponding to the position of the box shaft hole 42. The cylinder 44 is installed on the bottom of the door body upper shell 22 and corresponds to the box shaft hole 42. The damping shaft 43 is arranged in the two cylinders 44. The damping spring 45 is arranged on one side of the two damping shafts 43. The damping spring 45 can make a certain stroke extension and contraction movement. When assembling, the damping shaft 43 is aligned with the box shaft hole 42. The damping shaft 43 enters the box shaft hole 42 under the action of the elastic force. A small round stick presses the damping shaft 43 through the through hole of the stand ear 41 and the box shaft hole 42. The damping shaft 43 exits the box shaft hole 42. The door body assembly 2 can be disassembled. A plurality of clamping hooks 46 are symmetrically arranged on both sides of the door body lower shell 21. The buckle position 47 is arranged on the bottom of the door body upper shell 22 corresponding to the position of the clamping hook 46. The door body upper shell 22 and the door body lower shell 21 are quickly installed through the clamping hook 46 and the buckle position 47.
[0027] The hand unlocking assembly 3 comprises a lower shell 31 arranged on the door body lower shell 21. The door body upper shell 22 is hollow corresponding to the position of the lower shell 31. The upper shell 32 corresponding to the lower shell 31 is arranged on the bottom of the door body upper shell 22. The upper shell 32 is provided with a hand 33. The hand 33 is a component operated by the user, which can unlock the door body assembly 2 and the box assembly 1. After the upper shell 32 and the lower shell 31 in the hand unlocking assembly 3 are combined, the hand unlocking assembly 3 is assembled with the door body upper shell 22. After the door body lower shell 21 is foamed and molded with the foaming mold by the naked bubble process, the door body lower shell 21 is combined with the door body upper shell 22. The flow of bubble liquid into the hand unlocking assembly 3 affects the smoothness of the movement of the hand unlocking assembly 3. The door body upper shell 22 and the door body lower shell 21 are combined through the clamping hook 46 and the buckle position 47. The assembly process is simple.
[0028] The middle part of the lower shell 31 is provided with a lock tongue translation track 315, and a pair of lock tongues 310 are symmetrically arranged on both sides of the lock tongue translation track 315. The lock tongue translation track 315 provides a path for the movement of the lock tongue 310, and the lock tongue 310 moves in the track to realize the locking and unlocking functions of the door body assembly 2. The middle part of the lock tongue translation track 315 is provided with a handle rotating shaft 34, and the handle rotating shaft 34 is provided with a lock tongue connecting piece 36 on one side. A pair of upper and lower guide rails 38 are symmetrically arranged on both sides of the lock tongue translation track 315 of the handle rotating shaft 34. The lock tongue connecting piece 36 is provided with upper and lower guide shafts 37 corresponding to the positions of the upper and lower guide rails 38 on the front and back sides. When an external force is applied to the handle 33, the handle 33 rotates around the handle rotating shaft 34, and the lower part of the handle 33 drives the lock tongue connecting piece 36 to move up and down. The lock tongue connecting piece 36 moves stably along the upper and lower guide rails 38 through the upper and lower guide shafts 37. A pair of guide shafts 39 are symmetrically arranged at both ends of the lock tongue connecting piece 36. The tail parts of the two lock tongues 310 are provided with 45° guide grooves 311 corresponding to the positions of the guide shafts 39. The guide shafts 39 and the 45° guide grooves 311 cooperate to ensure that the lock tongue 310 moves stably along the predetermined path when the lock tongue connecting piece 36 moves. The 45° guide grooves 311 and the guide shafts 39 at both ends of the lock tongue connecting piece 36 cooperate to convert the up-and-down movement of the lock tongue connecting piece 36 into the horizontal expansion and contraction movement of the lock tongue 310, thereby realizing unlocking. The handle rotating shaft 34 is provided with a torsional spring 35, one end of which is connected to the handle 33, and the other end thereof is connected to the upper shell 32. When an external force is applied to the handle 33, the torsional spring 35 is compressed to generate elastic potential energy. When the external force disappears, the elastic potential energy of the torsional spring 35 is released to restore the original state, so that the handle 33 returns to the original position.
[0029] The lock tongue translation track 315 is symmetrically provided with a pair of baffles 316 on both sides, and each of the two baffles 316 is provided with a lock tongue return spring 313 on one side. The two lock tongue return springs 313 are connected with the lock tongue 310 at the ends away from the baffles 316. The lock tongue return spring 313 and the baffle 316 are located in the middle part of the lock tongue 310. When the two lock tongues 310 are contracted to the middle part under the action of external force, the lock tongue return spring 313 will be extruded. When the external force disappears, the lock tongue return spring 313 will restore to the original state and push the lock tongue back to the lock tongue translation guide track 314. The box top cover 11 is symmetrically provided with a pair of lock tongue translation guide tracks 314 on the left and right sides corresponding to the positions of the lock tongue 310. The lock tongue translation guide track 314 is arranged on the left and right sides of the box top cover 11 and corresponds to the lock tongue 310. When the refrigerator is closed, the lock tongue 310 will be clamped into the lock tongue translation guide track 314 under the action of the elastic force. The lock tongue connecting piece 36 is symmetrically provided with a pair of lock tongue connecting piece return springs 312 on both sides. The two lock tongue connecting piece return springs 312 are connected with the lower shell 31 at the ends away from the lock tongue connecting piece 36. The lock tongue connecting piece return spring 312 connects the lock tongue connecting piece 36 and the lower shell 31 and provides a restoring force for the lock tongue connecting piece 36, so as to ensure that the lock tongue connecting piece 36 can automatically return to the initial position after being unlocked.
[0030] In use, if the user needs to use the refrigerator, the user can hold the buckle hand 33 and buckle it up. The buckle hand 33 makes a turning motion around the buckle hand rotating shaft 34. At this time, the torsional spring 35 connected with the buckle hand 33 is extruded. The lower bone of the buckle hand 33 drives the lock tongue connecting piece 36 to move downward along the upward and downward guide track 38. At this time, the lock tongue connecting piece return spring 312 on both sides of the lock tongue connecting piece 36 is compressed. The guide shaft 39 at both ends of the lock tongue connecting piece 36 moves downward along the 45° guide groove 311 at the tail of the lock tongue 310, so as to realize the contraction of the two lock tongues in the horizontal direction. At this time, the lock tongue 310 extrudes the lock tongue return spring 313 inward, so that the head of the lock tongue 310 is separated from the lock tongue translation guide track 314. The user can lift the door assembly 2 upward to store or take out the required items from the refrigerator.
[0031] After the refrigerator is opened, the user's hand can leave the buckle hand 33. When the external force disappears, the torsional spring 35 restores to the original state and drives the buckle hand 33 to return to the original position. The lock tongue connecting piece return spring 312 returns, so as to reset the lock tongue connecting piece 36 and realize the opening of the two lock tongues 310 in the horizontal direction. At the same time, the extruded lock tongue return spring 313 releases the elastic potential energy and pushes the lock tongue 310 outward. When the user needs to close the refrigerator door, the user can push the door assembly 2. After the lock tongues 310 on both sides hit the lock tongue translation guide track 314, they will first contract and then pop out under the action of the lock tongue return spring 312, so as to automatically insert into the lock tongue translation guide track 314 and realize the sealing function of the refrigerator.
[0032] If the user needs to disassemble the door body assembly 2, a small round stick can be used to press the damping shaft 43 through the through hole of the vertical ear 41 and the shaft hole 42 of the box body, and the damping shaft 43 exits the shaft hole 42 of the box body, so that the door body assembly 2 can be disassembled. When assembling the door body assembly 2 and the box body assembly 1, only the damping shaft 43 needs to be aligned with the shaft hole 42 of the box body, and the damping shaft 43 enters the shaft hole 42 of the box body under the elastic force of the damping spring 45, so that the assembly of the door body assembly 2 and the box body assembly 1 is completed.
