Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a device for resisting cabinet opening deformation. Background Art

[0002] With the improvement of living standards, people's demand for frozen and refrigerated foods is increasing, and the storage function of refrigerators for foods is becoming more and more significant. Due to many reasons such as the cooling of the box after foaming, the temperature difference between the inside and outside during refrigeration, and the load-bearing capacity of the box, the middle of the cabinet opening on the front and back sides of the refrigerator swells outward. Severe deformation of the box not only affects the appearance of the refrigerator, but also affects the overall performance of the refrigerator. This has always been a problem that has troubled refrigerator manufacturers; excessive deformation of the box will cause many problems in the refrigerator. First of all, the deformation of the box will affect the assembly of the door body, the use of drawers and shelves, and in severe cases, it will also affect the sealing of the refrigerator box and the door seal, thereby affecting the energy efficiency, refrigeration and preservation performance of the refrigerator.

[0003] Since large-volume freezers have longer cabinets, when the temperature difference between the inside and outside of the freezer is large, the deformation of the cabinet opening will be more obvious. In the past, in order to reduce the deformation of a single cabinet, the most commonly used method was to add a reinforcing iron inside or at the bottom of the cabinet frame along the length direction of the cabinet frame. This has a certain effect on maintaining the flatness of the side walls, but for the problem of box expansion and deformation, because there is no corresponding force to balance the force that causes the box expansion and deformation, box expansion and deformation will still occur. The use of local reinforcement methods not only increases the cost of materials and production processes, but also has a poor actual effect. Utility Model Content

They only represent relative position relationships, not absolute position relationships.

[0026] like Figures 1 to 5 As shown together, a device for resisting deformation of a cabinet opening comprises a rectangular box surface frame 1, an anti-deformation device is arranged between two opposite side frames 2 of the box surface frame 1, the anti-deformation device comprises a reinforcing plate 3 fixedly arranged in the side frames 2, a connecting rod 4 is fixedly arranged on the reinforcing plate 3, two connecting rods 4 are relatively arranged between the two side frames 2, the connecting rod 4 extends to the middle of the box surface frame 1, the two connecting rods 4 are arranged in parallel and staggered, a rack 5 is arranged at the end of the connecting rod 4, the tooth surface of the rack 5 is located on the inner side of the connecting rod 4, a gear 6 meshing with the rack 5 is connected between the two racks 5, the central axis of the gear 6 extends out and is connected to the knob 7; rotating the knob 7 drives the gear 6 to rotate, converting the rotation of the gear 6 into the translation of the rack 5, thereby shortening the distance between the two connecting rods 4 in the length direction, thereby correcting the deformation of the box surface frame 1; the outside of the anti-deformation device is wrapped with a decorative cover 8, the knob 7 is arranged on the decorative cover 8, and the appearance and color of the decorative cover 8 are consistent with the overall product.

[0027] Furthermore, because the deformation of the long frame 2 is relatively large and the maximum deformation is in the middle of the frame 2, the anti-deformation device is set on the long frame 2 of the box surface frame 1, and is set at the center of the long frame 2 of the box surface frame 1.

The reinforcing plate 3 and the box surface frame 1 become a whole after foaming. The box surface frame 1 is generally made of a plastic material. The reinforcing plate 3 is arranged in the frame 2 of the box surface frame 1. On the one hand, it can increase the strength of the box surface frame 1, disperse the tensile force, and reduce its deformation caused by thermal expansion and contraction. On the other hand, it can be used to fix the anti-deformation device.

[0029] Furthermore, in order to prevent the gear 6 from reversing after the anti-deformation device is adjusted and affecting the anti-deformation effect, an anti-reversal mechanism 9 is also arranged on the side of the rack 5.
