DETAILED DESCRIPTION

[0022] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0023] See also Figure 1-6 , the utility model provides a technical solution:

[0024] An ice cream cabinet with a top-hung window type gravity automatic door closing structure comprises a refrigerator body 1, a pick-up window 11 opened and closed by a pick-up door 2 is arranged at the bottom of one side of the refrigerator body 1, a lock slot 12 is arranged at the bottom of the inner wall of the pick-up window 11, an infrared sensor 13 is arranged above the pick-up window 11 on one side of the refrigerator body 1, a magnetic sealing seat 14 is arranged on the inner wall of the pick-up window 11, hinges 3 for controlling the opening and closing angle of the pick-up door 2 are arranged on both sides of the inner wall of the pick-up window 11, and a magnetic sealing seat 14 is arranged on the inner side of the pick-up door 2. A magnetic sealing strip 23 is adapted to each other, a mounting groove 21 is provided at the bottom of the pickup door 2, connecting shafts 22 connected to the pickup window 11 are provided on both sides of the top of the pickup door 2, a locking mechanism 25 is provided in the inner cavity of the mounting groove 21, and a door handle 24 is provided on the front of the pickup door 2 at a position corresponding to the locking mechanism 25. The hinge 3 includes a positioning seat 31, and a movable groove 32 is provided on the inner wall of the positioning seat 31. A slide plate 33 is movably connected to the inner wall of the movable groove 32, and a lifting arm 34 is connected to one side of the hinge 3, and one end of the lifting arm 34 is connected to the inner side of the pickup door 2.

[0025] In this embodiment, please refer to Figure 5-6, buffer members 35 are provided on both sides of the slide plate 33, and a number of buffer holes 322 are opened on both sides of the inner wall of the movable groove 32. The buffer member 35 includes a sleeve 351, and the inner wall of the sleeve 351 is provided with a second spring 352. One end of the second spring 352 is provided with an embedded ball 353 adapted to the buffer hole 322. In this embodiment, when the slide plate 33 moves downward along the inner wall of the movable groove 32, the buffer member 35 cooperates with the buffer hole 322 to continuously provide a buffering force to the slide plate 33, so that the descending speed of the slide plate 33 slows down, thereby slowing down the closing speed of the pickup door 2, effectively preventing the pickup door 2 from closing too quickly and causing the user's hands to be pinched.

[0026] In this embodiment, please refer to Figure 3-4 The door handle 24 includes a fixing seat 241, a control member 242 is provided on one side of the fixing seat 241, and a control block 243 is fixedly connected to one end of the control member 242. The locking mechanism 25 includes a lock tongue 251 that is compatible with the lock groove 12, a linkage block 252 is provided on one side of the lock tongue 251, and a first spring 253 is provided on the top of the lock tongue 251. The corresponding surfaces of the control block 243 and the linkage block 252 are arranged as inclined surfaces that are compatible with each other, and the linkage block 252 can be pushed to move upward by the control block 243. In this embodiment, the control block 243 is moved forward by pushing the control member 242. Due to the corresponding inclined surfaces of the control block 243 and the linkage block 252, the linkage block 252 is subjected to the thrust to drive the lock tongue 251 to move upward, so that the lock tongue 251 can be separated from the inner cavity of the lock groove 12, and the pickup door 2 can be pulled to open the pickup window 11.

[0027] In this embodiment, please refer to Figure 4 , the contact surface between the lock tongue 251 and the pickup window 11 is set as an inclined surface. In this embodiment, when the pickup door 2 is closed, since the contact surface between the lock tongue 251 and the pickup window 11 is set as an inclined surface, under the suction force of the magnetic sealing seat 14 and the magnetic sealing strip 23, the inclined surface of the lock tongue 251 contacts the bottom of the pickup window 11, pushing the lock tongue 251 to move upward, and squeezing the first spring 253 to deform it, so that the pickup door 2 continues to close. When the lock tongue 251 moves to the top of the lock slot 12, the first spring 253 loses pressure and rebounds, so that the lock tongue 251 is embedded in the inner cavity of the lock slot 12, so that the pickup door 2 is locked.

[0028] In this embodiment, please refer to Figure 5, an electromagnet 321 is provided on the top of the inner wall of the movable groove 32, and metal blocks 331 that attract the electromagnet 321 are provided on both sides of the slide plate 33. In the present embodiment, when the slide plate 33 moves to a certain height along the inner wall of the movable groove 32, the metal blocks 331 and the electromagnet 321 attract each other, so that the slide plate 33 cannot continue to move upward, and the position of the slide plate 33 is fixed, so that the pickup door 2 is maintained at the maximum opening and closing angle, which is convenient for the user to take out the goods with both hands. At the same time, when the infrared sensor 13 detects that the user leaves the vicinity of the refrigerator body 1, the power supply inside the refrigerator body 1 stops supplying power to the electromagnet 321, so that the suction force between the electromagnet 321 and the metal block 331 disappears, and the pickup door 2 automatically closes due to its own gravity.

[0029] In this embodiment, please refer to Figure 6 An anti-slip ring is provided on the outer side of the embedded ball 353, an anti-slip groove is provided on the inner wall of the sleeve 351, and the anti-slip ring moves along the inner wall of the anti-slip groove. In this embodiment, when the position of the embedded ball 353 moves, the cooperation between the anti-slip groove and the anti-slip ring can prevent the embedded ball 353 from escaping from the inner cavity of the sleeve 351.

[0030] Working principle of this utility model:

[0031] When the control member 243 is pressed, the control block 243 is pushed forward by the control member 242. Since the control block 243 and the linkage block 252 are provided with corresponding inclined surfaces, when the control block 243 moves forward, the linkage block 252 is pushed upward, so that the lock tongue 251 moves upward, and the first spring 253 is squeezed and deformed. After the lock tongue 251 moves upward, it disengages from the inner cavity of the lock groove 12, and the lifting arm 34 is rotated by pulling the door handle 24, and the slide plate 33 is driven to move upward along the inner wall of the movable groove 32, so that the picking window 11 is opened, and the picking operation is performed. After the picking is completed, as the slide plate 33 moves upward farther, the opening angle of the picking door 2 becomes larger, and when the slide plate 33 moves to the electromagnet 321, the metal block 331 and the electromagnet 321 attract each other, so that the position of the slide plate 33 is fixed, so that the opening angle of the picking door 2 is fixed, and at this time, there is no need to hold the door handle 24, which is convenient for the user to perform the picking operation with both hands;

[0032] Step 2, after the goods are picked up, the user leaves the side of the refrigerator body 1, and the infrared sensor 13 senses that the user has left, and the power supply inside the refrigerator body 1 stops supplying power to the electromagnet 321, so that the electromagnet 321 loses its magnetic force, so that the position of the slide plate 33 is no longer fixed, and the slide plate 33 automatically slides down along the inner wall of the movable groove 32 due to the gravity of the goods picking door 2, and the opening angle of the goods picking door 2 also becomes smaller until it is closed, and by providing a buffer member 35, during the downward movement of the slide plate 33, after the embedded ball 353 moves to the inner cavity of the buffer hole 322, the movement of the slide plate 33 is paused, and the embedded ball 353 moves to the inner cavity of the buffer hole 322 under the action of gravity. The ball 353 continues to disengage from the inner cavity of the withdrawal buffer hole 322, causing the pickup door 2 to pause and provide a buffering effect during the closing process. Since the inner wall of the movable groove 32 is provided with a plurality of buffer holes 322, the pickup door 2 continuously provides a buffering effect during the closing process through the cooperation between the buffer holes 322 and the buffer member 35. A magnetic sealing strip 23 and a magnetic sealing seat 14 that attract each other are provided on one side of the pickup door 2 and the inner wall of the pickup window 11. When the pickup door 2 is closed, the magnetic sealing seat 14 and the magnetic sealing strip 23 are adsorbed and fitted, thereby enhancing the sealing effect after the pickup door 2 is closed and avoiding temperature loss inside the freezer body 1.
