First flanges 110 and second flanges 120 are respectively provided on the inner walls on the left and right sides of the hinge seat cover 100. A third flange 210 is provided on the outer wall on the left side of the fixed bottom plate 200, and a snap 220 is provided on the right side of the fixed bottom plate 200. By snap-connecting the first flange 110 with the third flange 210 and the second flange 120 with the snap 220, the hinge seat cover 100 is snap-fitted on the fixed bottom plate 200. Pushing the hinge seat cover 100 to the left can compress the snap 220 and cause the first flange 110 and the third flange 210 to be dislocated and separated from each other.

[0029] Working principle:

[0030] (1) Quick installation: The hinge seat cover 100 is inserted downward from above the fixed bottom plate 200. The first flange 110 and the second flange 120 will respectively pass by the third flange 210 and the snap 220. The snap 220 is pressed inward by the extrusion force of the second flange 120. When the second flange 120 completely passes through the snap 220, the snap 220 loses the extrusion force and rebounds to its original position, thereby snap-fitting and locking the hinge seat cover 100 on the fixed bottom plate 200, as Figure 4 shown.

[0031] (2) Quick disassembly: Push the hinge seat cover 100 to the left. The inner side thereof contacts the snap 220 and compresses the snap 220, causing the first flange 110 and the third flange 210 to be dislocated and separated from each other. Then lift the left side of the hinge seat cover 100 upward, so that the hinge seat cover 100 is completely separated from the fixed bottom plate 200, completing the disassembly, as Figure 5 shown.

[0032] In some embodiments of the present invention, a receiving groove 230 is formed on the other side of the fixed bottom plate 200. The snap 220 includes an elastic part 221 and a snap-connecting part 222. The elastic part 221 is installed in the receiving groove 230, and the snap-connecting part 222 extends out of the receiving groove 230. The snap-connecting part 222 outside the receiving groove 230 is used for snap-connecting with the second flange 120. When the snap-connecting part 222 is subjected to the extrusion force of the second flange 120, the elastic part 221 in the receiving groove 230 will be compressed.

[0033] In some embodiments of the present invention, a through hole 240 is formed on the side wall on the other side of the fixed bottom plate 200. The through hole 240 communicates with the receiving groove 230, and the snap-connecting part 222 passes through the fixed bottom plate 200 through the through hole 240.

[0034] In some embodiments of the present utility model, the upper surface of the snap - connection portion 222 is an inclined surface, which slopes downward from the end close to the fixed bottom plate 200 towards the end away from the fixed bottom plate 200. The inclined surface facilitates the second flange 120 to push the snap - connection portion 222 when the hinge seat cover 100 is inserted from top to bottom.

[0035] In some embodiments of the present utility model, the elastic portion 221 is a spring piece or a spring.

[0036] In some specific embodiments of the present utility model, the elastic portion 221 is a spring piece, and the spring piece and the snap - connection portion 222 are of an integrally formed structure. The integral forming can be completed at one time through processes such as injection molding and stamping, reducing the complexity of part manufacturing and production costs. At the same time, due to the reduction of the number of parts and assembly steps, the production efficiency is significantly improved.

[0037] In some embodiments of the present utility model, the upper surface of the third flange 210 is an inclined surface, which slopes downward from the end close to the fixed bottom plate 200 towards the end away from the fixed bottom plate 200. When the hinge seat cover 100 is inserted from top to bottom, the first flange 110 can slide along the inclined surface to smoothly cross over the third flange 210, realizing the snap - connection between the first flange 110 and the third flange 210.

[0038] In some embodiments of the present utility model, the four - peripheral edges of the hinge seat cover 100 have downward - extending edge guards 130. The first flange 110 and the second flange 120 are respectively located on the edge guards 130 on the left and right sides of the hinge seat cover 100, and the fixed bottom plate 200 is embedded in the space surrounded by the edge guards 130. The edge guards 130 around the hinge seat cover 100 are beneficial for circumferential positioning and fixing, avoiding structural shaking, and having strong installation stability; the edge guards 130 around the hinge seat cover 100 form a fully - enclosed structure, which is sleeved on the fixed bottom plate 200 for locking, making the hinge as a whole simple and beautiful.

[0039] In some embodiments of the present utility model, taking the length direction of the fixed bottom plate 200 as the left - right direction, the third flange 210 and the snap - fastener 220 are respectively arranged on the left and right sides of the fixed bottom plate 200.
