Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to an upper and lower cover structure of a flip beam for preventing cracking. Background Art

[0002] Refrigerators have become an indispensable household appliance in people's daily lives. As people's living standards are getting better and better, more families use large-capacity refrigerators, and the refrigerator compartments are all double-door structures. The flip beam is generally installed on the left door of the refrigerator compartment. When the door body is opened and closed, the flip beam rotates from the stowed position to the unfolded position to seal the gap between the two doors to prevent cold air leakage.

[0003] Normally, the upper and lower covers of the flip beam are connected by claws or screws. The claw structure has the risk of disengagement under long-term use and high tension, which leads to market complaints, returns, repairs and other after-sales services; the screw structure has low production efficiency, unsightly appearance, and low customer acceptance.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 4 As shown, the utility model is an upper and lower cover structure for preventing a flip beam from cracking, comprising an upper cover body 1 and a lower cover body 2, wherein the upper cover body 1 and the lower cover body 2 are combined to form a flip beam body;

[0028] Specifically, the upper cover body 1 and the lower cover body 2 are integrally injection molded by an injection mold, so that the integrity and aesthetics of the cover bodies are better and the molding efficiency is high.

[0029] The upper cover body 1 comprises an upper cover plate 11, an upper arc connecting plate 12 is fixedly provided on one side of the upper cover plate 11 along the length direction, and a sealing side plate 13 is fixedly provided on the other side of the upper cover plate 11 along the length direction;

[0030] The lower cover body 2 includes a lower cover plate 21, and a side panel 22 matching the sealing side panel 13 is provided on one side of the lower cover plate 21 along the length direction, and a lower arc connecting plate 23 matching the upper arc connecting plate 12 is provided on the other side of the lower cover plate 21 along the length direction. Side sealing plates 26 are fixedly provided on both sides of the lower cover plate 21 along the width direction.

[0031] An end face latch 16 is fixedly provided on one side of the width direction of the upper cover plate 11, and an end face socket 27 matching with the end face latch 16 is provided on a sealing plate 26 at one end of the lower cover plate 21. The cooperation between the end face latch 16 and the end face socket 27 limits the connection between the upper cover body 1 and the lower cover body 2, which can effectively prevent the flip beam from cracking during use.

[0032] A plurality of claws 14 are provided on one side of the upper cover plate 11 close to the upper arc connecting plate 12, and a buckle 24 cooperating with the claw 14 is provided at a position corresponding to the claw 14 of the lower cover plate 21. The cooperation between the claw 14 and the buckle 24 makes the connection between the upper cover body 1 and the lower cover body 2 more stable.

[0033] Reinforcement plates 241 are provided on both sides of the buckle 24, and the reinforcement plates 241 are fixedly connected to the side panels 22. The provision of the reinforcement plates 241 improves the overall strength of the buckle 24, thereby improving the overall connection strength between the upper cover body 1 and the lower cover body 2.

[0034] A plurality of second claws 15 are fixedly provided on one side of the upper cover plate 11 close to the sealing side plate 13, and a second buckle 25 cooperating with the second claw 15 is provided on the lower cover plate 21. The cooperation between the second claw 15 and the second buckle 25 makes the connection between the upper cover body 1 and the lower cover body 2 more stable.

[0035] The upper cover plate 11 is provided with matching grooves 18 on both sides in the width direction for avoiding the side sealing plates 26. The matching grooves 18 are provided to improve the tightness of the connection between the side sealing plates 26 of the lower cover body 2 and the upper cover body 1. At the same time, the provision of the matching grooves 18 improves the overall strength of the matching installation between the upper cover body 1 and the lower cover body 2.

[0036] A sealing convex plate 17 is provided on the side of the upper cover plate 11 away from the end face pin 16, and the side sealing plate 26 of the lower cover body 2 is pressed by the sealing convex plate 17, thereby ensuring the tightness and connection strength between the upper cover body 1 and the lower cover body 2, and improving the overall strength of the entire flip beam.

[0037] The sealing side plate 13 is provided with a plurality of avoidance notches 19. The avoidance notches 19 can avoid the internal structure of the lower cover body 2. At the same time, the avoidance notches 19 separate the sealing side plates 13, effectively preventing the sealing side plates 13 from deforming due to thermal expansion and contraction. In addition, the notches can reduce the molding material of the upper cover body 1 on the one hand, and facilitate demoulding during injection molding on the other hand.

[0038] The working principle of the utility model is as follows: when installing the flip beam, first align the end face pin 16 of the upper cover body 1 with the end face socket 27 of the lower cover body 2, then insert the end face pin 16 into the end face socket 27, and then make the claw 14 and the claw 2 15 correspond to the buckle 1 24 and the buckle 2 25 one by one, and then press the upper cover body 1 and the lower cover body 2 so that the two are buckled and connected to each other as a whole, thereby completing the assembly and splicing of the flip beam.

[0039] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
