[0025] The utility model is further described below in conjunction with the accompanying drawings.

[0026] According to the attached Figures 1 to 5 As shown, the flap hinge with quick locking and assembly function of the utility model comprises a door body mounting assembly 1 and a cabinet connecting assembly, wherein the cabinet connecting assembly comprises a cabinet bracket 2, a swing arm 3, and a power source 4, wherein the power source 4 is mounted on the cabinet bracket 2 and acts elastically on the swing arm 3, and the connecting portion of the swing arm 3 is riveted to the swinging portion of the door body mounting assembly 1. A quick locking device is provided between the positioning portion of the door body mounting assembly 1 and the cabinet bracket 2. The quick locking device comprises a main shaft 5 and a locking spring 6, wherein the positioning portion of the locking spring 6 is riveted to the door body mounting assembly 1, and the elastic portion of the locking spring 6 is provided with an axial hole 61, wherein the main shaft 5 is fixed to the cabinet bracket 2, and the door body mounting assembly 1 is provided with an open guide groove 13, wherein the main shaft 5 slides along the open guide groove 13 while lifting the locking spring 6 so as to slide onto the axial hole 61, so as to cause the locking spring 6 to lock the main shaft 5 on the door body mounting assembly 1 under the action of its reset elasticity.

[0027] Through the structural coordination of the main shaft 5 and the locking spring 6 of the quick locking device, the structure is simple, so that the door body installation component 1 and the cabinet bracket 2 can be quickly disassembled and assembled, and maintenance is easy. At the same time, the probability of collision between the door body bracket 11 and the cabinet bracket 2 is effectively reduced, ensuring the normal use of the product.

[0028] Reference Figures 1 to 5 As shown, the open guide groove 13 is configured as an open guide arc groove extending toward the shaft hole 61. Moreover, the locking spring piece 6 has an elastic portion providing a 2-5 degree prestress; the elastic portion of the locking spring piece 6 is provided with a guide inclined surface 62 for lifting the main shaft 5, and the main shaft 5 contacts the guide inclined surface 62 while moving.

[0029] That is, during assembly, the spindle 5 enters the port of the open guide arc groove, and at the same time, the spindle 5 contacts the guide inclined surface 62 of the locking spring 6, thereby increasing the contact area, increasing the connection stability, and ensuring smooth assembly. Then, the spindle 5 is pushed to move along the open guide arc groove toward the shaft hole 61, so that the spindle 5 pushes up the elastic part of the locking spring 6. Subsequently, the spindle 5 slides to the arc groove position of the open guide arc groove and enters the shaft hole 61, so that the elastic part of the locking spring 6 is elastically reset, so that the locking elastic buckle is mounted on the spindle 5. The operation is simple and the structural stability is ensured.

[0030] During this period, the shaft hole 61 is provided with a limit block 63 for preventing the main shaft 5 from being separated from the shaft hole 61. The limit block 63 is clamped on the end face of the main shaft 5 to prevent the main shaft 5 from being separated from the shaft hole 61 during operation, thereby improving the structural stability.

[0031] In addition, the positioning portion of the locking spring piece 6 is riveted to the door body mounting assembly 1 through the spring piece rivet 7. A bending buckle block 64 is provided in the middle of the locking spring piece 6 to prevent displacement, and the door body mounting assembly 1 is provided with a buckle hole 14 for buckling with the bending buckle block 64. The structure of the spring piece rivet 7, the bending buckle block 64 and the buckle hole 14 is used to prevent the locking spring piece 6 from shifting during the operation of the hinge, thereby enhancing the structural stability and ensuring the normal use of the hinge.

[0032] Reference Figures 1 to 5 As shown, in further detail, the movable part of the swing arm 3 is buckled on the power source 4, and the connecting part of the swing arm 3 is riveted to the swing part of the door body mounting assembly 1 through the connecting rivet 8. The swing part of the door body mounting assembly 1 is installed with a rivet sleeve 9 for rotating with the connecting rivet 8. Under the structural effect of the rivet sleeve 9, the connecting rivet 8 is prevented from being directly connected to the door body mounting assembly 1 and the swing arm 3, reducing friction damage and improving the smoothness and stability of rotation.

[0033] Among them, the door body installation assembly 1 includes a door body bracket 11 and a connecting rack 12. The door body bracket 11 is provided with a connecting rivet 8 for riveting with the swing arm 3, an open guide groove 13 adapted for sliding with the main shaft 5, and a buckle hole 14 on one side of the open guide groove 13. The connecting rack 12 is installed on the door body bracket 11, and the connecting part of the swing arm 3 is provided with teeth 31 for meshing and connecting with the connecting rack 12 as the door body bracket 11 swings.

[0034] The door body bracket 11 of the door body installation assembly 1, the connecting rack 12 and the teeth 31 of the swing arm 3 are meshed and connected, so that the swing arm 3 and the door body bracket 11 are linked to achieve the sliding and flipping door action effect, effectively and accurately controlling the displacement of the door body according to the rotation angle, reducing the mutual interference between the door body and the cabinet body, and ensuring stable and smooth operation.

[0035] The above specific embodiments are only specific implementation methods with better effects of the utility model. Any structure that is the same or equivalent to the flap hinge with quick locking and assembly function of the utility model is within the protection scope of the utility model.
