Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a hinge with a locking function. Background Art

[0002] The hinge is currently the most commonly used connecting part for rotating and opening and closing the door body. In order to realize the self-opening of the door body, there is a refrigerator door closing device with an arbitrary hovering function. The Chinese patent number is: CN201811035518.3, which discloses a hinge shaft fixed to the upper end of the refrigerator cabinet and a hinge seat fixed to the upper end of the refrigerator door body. The positioning end of the hinge seat is sleeved on the hinge shaft and its swing end rotates with the hinge shaft as a fixed point. The hinge seat is equipped with a cam, a connecting wheel and an elastic component. The cam is fixedly sleeved on the hinge shaft, and the outer edge of the cam is provided with a positioning groove and an arc surface. The elastic component elastically buffers the connecting wheel so that the connecting wheel is connected to the positioning groove and the arc surface by sliding as the hinge seat rotates.

[0003] However, although the above structural hinge can make the door body close automatically, it has the following shortcomings in practical applications:

[0004] 1. The cam and the connecting wheel are matched, which has many parts, complex structure and poor stability;

[0005] 2. After long-term use, there is great wear and tear between the positioning groove and the arc surface, resulting in large gaps and poor locking effect;

[0006] Therefore, the conventional refrigerator hinge still needs to be further improved. Utility Model Content

[0009] According to the above optimization, guide grooves are respectively provided on both sides of the fixing seat, and the deformable stop block and the stop sheet of the self-locking component are arranged at the lower end of the guide groove on one side.

[0010] Alternatively, guide grooves are respectively provided on both sides of the fixing seat, and the deformable stop block and the stop sheet of the self-locking component are arranged at the lower ends of the guide grooves on both sides.

[0011] According to the above optimization, the outer edge of the deformable stop block is provided with a guide arc outer edge which is connected to the guide groove and can guide the sliding shaft to slide smoothly in the locking buckle position.

[0027] The utility model is further described below in conjunction with the accompanying drawings.

[0028] According to the attached Figures 1 to 8 As shown, the hinge with locking function of the utility model comprises a fixed seat 1 installed on the cabinet body and a swing arm 2 for the door body to rotate and open and close, and the positioning end of the swing arm 2 is rotatably connected to the fixed seat 1 through a rotating shaft 3. Among them, the fixed seat 1 is provided with a self-locking component, and the self-locking component includes a deformable stop block 4 and a stop plate 5. The fixed seat 1 is provided with a guide groove 11 for limiting the up and down swinging of the swing arm 2, and the swing end of the swing arm 2 is installed with a sliding shaft 6 for sliding connection with the guide groove 11. The deformable stop block 4 and the stop plate are arranged at the lower end of the guide groove 11, and the deformable stop block 4 and the stop plate form a locking buckle 7. The sliding shaft 6 is slidably installed on the locking buckle 7 as the swing arm swings downward and under the action of the gravity of the swing arm 2, so that the two sides of the locking buckle 7 are respectively tangentially clamped and connected with the sliding shaft 6.

[0029] Reference Figures 1 to 8As shown, in further detail, guide grooves 11 are respectively provided on both sides of the fixing seat 1, and the deformable stop block 4 and the stop sheet 5 of the self-locking component are arranged at the lower end of the guide groove 11 on one side.

[0030] The outer edge of the deformable stopper 4 is provided with a guide arc outer edge 41 connected to the guide groove 11 and capable of guiding the sliding shaft 6 to slide smoothly on the locking buckle 7. The sliding shaft 6 is prompted to slide smoothly and stably into or out of the locking buckle 7 along the guide groove 11 and the guide arc outer edge 41, ensuring that the swing arm 2 is locked or unlocked on the fixing seat 1.

[0031] Moreover, the deformable stop block 4 is integrally connected to the side of the fixing seat 1, and the outer edge of the deformable stop block 4 is provided with a stop connection surface 42 for forming a locking buckle 7 with the stop plate 5, and the stop connection surface 42 is tangentially connected to the sliding shaft 6 in a sliding manner.

[0032] In addition, the positioning end of the stop plate 5 is integrally connected to the side of the fixing seat 1, and the connecting end of the stop plate 5 is provided with a locking vertical surface 51 for forming a locking buckle 7 with the deformable stop block 4, and the locking vertical surface 51 is tangentially connected to the sliding shaft 6 in a sliding manner.

[0033] In the optimized solution, the locking buckle 7 is configured as an inverted eight-shaped locking buckle 7 that is tangentially clamped and connected to the sliding shaft 6 as the swing arm 2 swings up and down, or is deformed to separate from the sliding shaft 6 when an external force is applied.

[0034] When closing, as the swing arm 2 swings downward, it can slide onto the locking buckle position 7 under the action of its own weight, and then cooperate with the elastic force of the stopper 5 to cause the sliding shaft 6 to be tangently clamped and connected with the locking vertical surface 51 of the stopper 5 and the stop connection surface 42 of the deformable stopper 4, respectively, so that the swing arm 2 is locked on the fixed seat 1. Under the dual action, the door body is stably locked on the cabinet body. At the same time, due to the cooperation of the locking vertical surface 51 and the stop connection surface 42, the tangent contact surface is increased, the structural stability is improved, and the locking effect is better. When opening, sufficient external force is applied to the swing arm 2 to overcome the dead weight while forcing the stopper 5 of the locking buckle position 7 to deform, so that the sliding shaft 6 slides away from the locking buckle position 7, and the door body is opened, which is convenient to operate.

[0035] Reference Figures 1 to 8As shown, in further detail, the fixed seat 1 is equipped with an assist elastic component 8 for assisting the swing arm 2 to open. The assist elastic component 8 includes a fixed card block 81, an elastic guide rod 82, and a push spring 83. The fixed card block 81 is mounted on the fixed seat 1, one end of the elastic guide rod 82 is mounted on the fixed card block 81, and the other end of the elastic guide rod 82 is mounted on the sliding shaft 6. The push spring 83 is sleeved on the elastic guide rod 82, and the two elastic ends of the push spring 83 are respectively connected to the fixed card block 81 and the elastic guide rod 82, so that the elasticity of the push spring 83 acts on the sliding shaft 6.

[0036] Cooperating with the structure of the power-assisting elastic component 8, the sliding shaft 6 can make the swing arm 2 swing outward by itself under the elastic action of the power-assisting elastic component, so as to realize automatic opening of the door body, which is easy to operate and suitable for use with doors with large loads.

[0037] It is worth noting that another embodiment is different from the above in that guide grooves 11 are respectively provided on both sides of the fixing seat 1, and the deformable stop block 4 and the stop sheet 5 of the self-locking component are arranged at the lower ends of the guide grooves 11 on both sides.

[0038] The above-mentioned self-locking components also use the deformable stopper block 4 and the stopper piece 5 to lock the swing arm 2 on the fixed seat 1, so that the door body is locked on the cabinet body, with high structural stability and good locking effect. When opening, sufficient external force is applied to the swing arm 2 to overcome its own weight and force the stopper piece of the locking buckle 7 to deform, so that the sliding shaft 6 slides away from the locking buckle 7, so that the door body is opened, and the operation is convenient.

[0039] This embodiment is only a specific implementation method of the utility model with better effects. All structures that are the same or equivalent to the hinge with locking function of the utility model are within the protection scope of the utility model.
