[0042] See Figure 4 The handle component has a handle box 2, and two handle cylinders 5 are fixedly connected to the handle box 2. The two handle cylinders 5 are slidably disposed in the support cylinder 31 of the pre-embedded box 3 on the corresponding side.

[0043] The handle box 2 is provided with a pressure plate 22, and two connecting rods 24 are fixedly connected to the pressure plate 22, which respectively extend into the handle cylinder 5 on the corresponding side; a button 21 protruding to the outside of the handle box 2 is also fixedly connected to the pressure plate 22; both the button 21 and the pressure plate 22 are provided with communicating air holes for introducing external air into the handle box 2 and the handle cylinder 5.

[0044] As one embodiment, the handle box 2 is also provided with a pressure plate return spring 23 with its two ends respectively abutting against the pressure plate 22 and the inner wall of the handle box 2; after the button 21 is pressed, the pressure plate return spring 23 is compressed and stores energy; after the button 21 is released, the pressure plate return spring 23 pushes the pressure plate 22 to reset.

[0045] Combination Figure 5 The handle 5 is provided with a slider seat 6, and a slider box 61 that can slide back and forth in a direction perpendicular to the connecting rod 24 is slidably provided in the slider seat 6.

[0046] The end of the connecting rod 24 is fixedly connected to the drive claw 241. The outer wall of the slider box 61 is provided with a sliding groove 611 that slides with the drive claw 241. The sliding groove 611 is inclined relative to the central axis of the connecting rod 24. One end of the slider box 61 is provided with a locking pin 62, and the other end is provided with a slider return spring 612 that abuts between the slider box 61 and the inner wall of the handle cylinder 5. The handle cylinder 5 is provided with a locking pin hole 52 for the locking pin 62 to pass through, and the inner wall of the support cylinder 31 is provided with a locking cavity for inserting and engaging with the locking pin 62.

[0047] Pressing button 21 causes pressure plate 22 to drive connecting rod 24 to press down, driving claw 241 to generate force in slide groove 611. Due to the axial constraint of connecting rod 24, slider box 61 moves laterally, locking pin 62 disengages from locking cavity, and handle 5 can slide in support cylinder 31.

[0048] When the pressure button 21 is released, the drive claw 241 moves upward, and the slider return spring 612 pushes the locking pin 62 to re-insert into the locking cavity, restoring the locked state.

[0049] Furthermore, a boss 311 is provided on the outer wall of the support cylinder 31, and the locking cavity is formed in the boss 311; so that the locking cavity has a certain wall thickness, improves the sealing performance, and avoids cold leakage.

[0050] See Figure 6 and Figure 7 The lower end of the support cylinder 31 is fixedly provided with a hollow air guide column 35; the part of the air guide column 35 located outside the support cylinder 31 forms the air outlet 32, and the part located in the support cylinder 31 is movably inserted into the handle cylinder 5; the lower end of the handle cylinder 5 is provided with a clearance hole 51 for receiving the air guide column 35.

[0051] The air guide column 35 is inserted into the threaded adjusting positioning ring 33 at one end of the handle cylinder 5, and the positioning column 63 is fixed on the slider box 61 and is fitted with the positioning ring 33 with a gap.

[0052] The positioning pin 63 is inserted into the positioning ring 33. The gap between the two is narrow, which blocks the connection between the air guide column 35 and the handle 5 and prevents flow leakage.

[0053] Positioning column 63 disengages from positioning ring 33, connecting handle 5 with air guide column 35, allowing air outside handle box 2 to enter defrost box 4, and then enter the cabinet through air outlet 41, balancing the air pressure difference inside and outside the cabinet.

[0054] Optionally, the positioning ring 33 has a protruding post that engages with the threaded part; and the positioning ring 33 has a through hole at its center for clearance engagement with the positioning post 63.

[0055] When opening the freezer lid, press button 21 to move the slider box 61 laterally, disengaging the locking pin 62 from the locking cavity; then pull the handle box 2 outward along the axial direction of the connecting rod 24. The positioning pin 63 disengages from the positioning ring 33, connecting the handle sleeve 5 to the air guide column 35, allowing air from outside the handle box 2 to enter the defrost box 4, and then into the freezer through the air outlet 41, balancing the air pressure difference inside and outside the freezer, thus allowing the freezer lid to be opened smoothly.

[0056] Optionally, when the handle box 2 is pulled to its limit position, the handle sleeve 5 abuts against the positioning ring 33 to limit the pull-out length of the handle box 2. The positioning ring 33 can adjust the pull-out length of the handle box 2; it can also finely adjust the position of the slider seat 6 so that, in the locked state, the locking pin 62 is aligned with the locking cavity.

[0057] Furthermore, the inner wall of the support cylinder 31 is provided with two locking cavities to limit the pull-out limit position of the handle box 2.

[0058] After the freezer lid is closed, push the handle box 2 in. During the pushing process, the locking pin 62 slides against the inner wall of the support cylinder 31. When pushed to the locking cavity position, the locking pin 62 enters the locking cavity under the action of the slider return spring 612.

[0059] This invention connects the handle to the defrost box 4. When the freezer lid is opened, the handle is connected to the defrost box 4, balancing the air pressure difference inside and outside the freezer and reducing opening resistance. When the freezer lid is closed, the handle is disconnected from the defrost box 4 to prevent cold air leakage. The defrost box 4 is filled with water-absorbing and bactericidal materials, ensuring that the air entering the freezer is dry and clean, preventing frost buildup and airway blockage.

[0060] As one embodiment, the handle cylinder 5 is provided with a support spring 34 sleeved on the outside of the air guide column 35; when the handle box 2 is pulled outward, the support spring 34 pushes the slider seat 6 to move synchronously.

[0061] In the locked state, the support spring 34 is in a compressed state. When the locking pin 62 separates from the locking cavity, the support spring 34 releases its elastic energy, pushing the slider seat 6 to move upward, so that the locking pin 62 can quickly disengage from the locking cavity.

[0062] As one embodiment, a spring post 613 is slidably provided inside the slider box 61. One end of the spring post 613 is movably connected to the slider return spring 612, and the other end is movably connected to the intermediate spring 614 located inside the slider box 61. When the driving claw 241 presses down, the slider box 61 moves laterally, and the intermediate spring 614 and the intermediate spring 614 contract simultaneously, reducing the resistance of the slider box 61 moving laterally.

[0063] As one embodiment, the slider seat 6 has a vent hole 64. After the locking pin hole 52 is disengaged from the locking cavity, the gas enters the air guide column 35 through the vent hole 64.

[0064] As one embodiment, the outer walls of the air outlet 32 ​​and the air inlet 42 are provided with raised rings to improve the stability of the connection with the air pipe.

[0065] This utility model also provides a freezer with the aforementioned handle-type ventilated freezer cover.

[0066] In summary, this utility model provides a handle-type ventilated freezer lid. By connecting the handle to the frost-blocking box, an air passage is formed. When the freezer lid is opened, the handle extends, the air passage is open, balancing the air pressure difference inside and outside the freezer and reducing opening resistance. When the freezer lid is closed, the handle retracts and simultaneously blocks the air passage, preventing cold air leakage. This utility model balances the ventilation and sealing of the lid. The frost-blocking box is filled with water-absorbing and antibacterial materials, ensuring that the air entering the freezer is dry and clean, preventing frost buildup and air passage blockage. This utility model also provides a freezer.
