Description

Technical Field

[0001] This utility model relates to the field of freezer door technology, specifically a self-rebound explosion-proof glass door for freezers. Background Technology

[0002] The freezer door is a crucial component of a freezer, serving to seal the internal space, maintain a low-temperature environment, and prevent cold air leakage and the entry of external hot air, dust, and bacteria. This ensures the effective refrigeration or freezing of items inside. During use, the freezer door needs to be closed promptly to prevent cold air loss. Currently, most freezer doors achieve automatic closing via magnetic door seals. These seals rely on magnetic force to attract the door to the freezer body, and when the door is opened and released, the magnetism causes the door to automatically close. However, the range of magnetic force is limited; it only works when the door is close to the freezer body. If the door is opened too wide, exceeding the range of magnetic force, the magnetic door seal cannot provide sufficient force to close the door. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this utility model provides a technical solution: a self-rebound explosion-proof glass door for a freezer, comprising: a door frame with sealing strips 18 installed on the side, the door frame including two horizontally arranged profiles 2 3, profiles 1 1 installed at the ends of the two support plates 13, profiles 1 1 and profiles 2 3 being connected by L-shaped iron sheets and screws; a hollow glass 2 installed in the middle of the door frame; a reset part placed inside one of the profiles 1 1, the reset part including a limiting block 15 installed inside the profile 1 1, a spring steel 12 installed on the top of the limiting block 15, a sleeve 14 sleeved on the outside of the spring steel 12 for supporting and guiding the spring steel 12, the sleeve 14 being fixed inside the profile 1 1 by the limiting member; a mounting plate 9 installed on the top of the profile 2 3 by bolts, and a rectangular rod 10 for driving the spring steel 12 to twist is rotatably connected to the top of the mounting plate 9.

[0016] It should be noted that in this embodiment, an upper limit plate is fitted on the outer side of the rectangular rod 10. The upper limit plate has a limiting hole that cooperates with the rectangular rod 10. The upper limit plate is fixed to the cabinet. A rotating shaft is installed at the bottom of the door frame. The rectangular rod 10 and the rotating shaft are coaxially arranged. After the metal plate is fitted on the outer side of the rotating shaft, the metal plate is fixed to the cabinet. When the glass door is opened, the profile 1 drives the bottom of the spring steel 12 to twist through the limiting block 15. The top of the spring steel 12 is limited by the rectangular rod 10 and the upper limit plate and remains unchanged. In this way, the spring steel 12 is twisted to store force. When the constraint on the glass door is removed, the spring steel 12 returns to its original position under the elasticity of the spring, causing the limiting block 15 to drive the profile 1 to return the door to its original position, thereby realizing automatic rebound. During the rotation of the spring steel 12, the sleeve 14 ensures that the spring steel 12 maintains the correct position during the rotation and avoids misalignment, thereby making the torsional effect of the spring steel more stable and ensuring the reliability of the reset mechanism.

[0017] In one embodiment, a filling hole 4 is provided in the middle of the profile 1, and a U-shaped glass mounting groove 5 is provided on one side of the profile 1. The insulating glass 2 is installed in the glass mounting groove 5, and a sealing strip 6 is installed on the inner wall of the glass mounting groove 5.

[0018] It should be noted that in this embodiment, the sealing strip is made of rubber, which can fill the gap between the glass and the groove, preventing air, moisture, dust, etc. from entering the groove. This improves the overall sealing performance, prevents heat or noise loss, and reduces moisture ingress. The limiting block 15 is installed in the filling hole 4, and the limiting block 15 cooperates with the inner wall of the filling hole 4. The filling hole 4 limits the limiting block 15, and the cooperation between the limiting block 15 and the filling hole 4 limits the bottom of the spring steel 12, preventing the bottom of the spring steel 12 from rotating.

[0019] In one embodiment, a connecting hook plate 16 is fixedly connected to the top of the limiting block 15, the bottom of the spring steel 12 is hooked to the middle of the connecting hook plate 16, and a limiting notch 17 that cooperates with the connecting hook plate 16 is opened at the bottom of the sleeve 14. The limiting member is a support plate 13, and a support plate 13 is fixedly connected to the outside of the sleeve 14. The support plate 13 is stuck in the filling hole 4.

[0020] It should be noted that in this embodiment, the spring steel 12 is connected to the limiting block 15 through the connecting hook plate 16. The spring steel 12 hooks the outside of the limiting block 15, forming a connection mechanism. The bottom of the spring steel 12 can be rotated by rotating the limiting block 15, so that the spring steel 12 can rotate or twist within a limited range through the connecting hook plate 16, and can provide the necessary elastic restoring force. Through the limiting of the support plate 13 and the limiting notch 17, the angle and position of the sleeve 14 can be fixed to prevent the sleeve 14 from being displaced during movement.

[0021] In one embodiment, a connecting shaft 11 is fixedly connected to the bottom of the rectangular rod 10, the connecting shaft 11 is rotatably connected to the mounting plate 9, a limiting liner 8 is fixedly connected to one side of the mounting plate 9, and the top of the spring steel 12 is hooked to the bottom of the connecting shaft 11.

[0022] It should be noted that in this embodiment, the profile 1 drives the bottom of the spring steel 12 to rotate through the limiting block 15 and the connecting hook plate 16. The top of the spring steel 12 is connected to the upper limiting plate through the connecting shaft 11 and the rectangular rod 10. Under the action of the limiting hole and the rectangular rod 10, the deformation of the spring steel 12 can be prevented, so that the spring steel 12 can be rotated to accumulate torsional force.
