Furthermore, the fixed plate 1 is provided with a second positioning portion 19 extending to the U-shaped groove, and in the fastening process, the second positioning portion 19 is attached to the inner wall surface of the side plate 33 to further guide and limit, so that the fastening state is prevented from moving left and right of the fastening piece 3.

In this embodiment, the side plate 33 is provided with a protruding portion 35 abutting against the fixed plate 1, that is, when the fastening state is performed, the protruding portion 35 abuts against the fixed plate 1, on one hand, the fastening member 3 can be prevented from loosening, and on the other hand, when the fastening member is detached, the protruding portion 35 plays a role of pushing open the fixed plate 1, so that the pressing portion 41 is quickly separated from the first fastening portion 11, and the quick detachment effect is realized.

In this embodiment, as shown in fig. 15, an arc-shaped groove 311 protruding outward is disposed inside the hook portion 31, when in a fastening state, the arc-shaped groove 311 blocks the second fastening position 21 to prevent the second fastening position 21 from moving back and forth inside the hook portion 31, a guide inclined surface 312 is disposed outside the hook portion 31, and when the second fastening position 21 abuts against the guide inclined surface 312, the second fastening position 21 can be guided to rapidly enter the arc-shaped groove 311.

The hinge assembly of the present embodiment has three snap-fit mounting modes: (1) as shown in fig. 17, the hook portion 31 of the fastener 3 hooks the second fastening position 21 of the elastic rod 2, the first fastening position 11 is located on the guide portion 42, and the first fastening position 11 enters the lower portion of the pressing portion 41 quickly by pressing the fastener 3 and pressing the guide portion 42, so that the fastener 3 and the base are fastened and mounted quickly. (2) As shown in fig. 18, the first engaging portion 11 is placed below the pressing portion 41, and the second engaging portion 21 is pushed to move in the direction of the first engaging portion 11 under the guidance of the guiding inclined surface 312 by pressing the engaging member 3, so that the second engaging portion 21 quickly enters the hook 31, and the quick engaging and mounting of the engaging member 3 and the base is realized. (3) As shown in fig. 19, at the same time, the first engaging position 11 is placed on the guiding portion 42, the second engaging position 21 is placed on the guiding inclined surface 312 of the hook portion 31, the engaging member 3 is pressed, and the first engaging position 11 presses the guiding portion 42 and the hook portion 31 pushes the second engaging position 21 to move, so that the first engaging position 11 quickly enters the lower portion of the pressing portion 41 and the second engaging position 21 quickly enters the hook portion 31, thereby realizing the quick engaging and mounting of the engaging member 3 and the base.

The hinge assembly of the embodiment is disassembled in the following way: the handle part 44 is pressed, so that the spring 5 is compressed, the pressing part 41 is driven to rotate, under the jacking action of the protruding part 35, the pressing part 41 is quickly separated from the first buckling position 11, and then the elastic rod 2 is taken out from the hook part 31, so that the quick detachment of the buckling piece 3 and the base is realized.

In summary, the embodiments of the present invention provide a hinge base and a hinge assembly, which have the following advantages: (1) the elastic deformation of the elastic rod 2 is utilized to realize that the second buckling position 21 can move relative to the first buckling position 11, and the quick installation of the buckling piece 3 and the base is realized; (2) the mounting groove 14, the movable groove 15, the first limiting part 12 and the mounting part 13 are formed in a stamping mode and are integrally formed, so that the cost is low and the stability is good; (3) the middle part of the fixed plate 1 can be set into an arc shape which is sunken towards the back surface, a damper of the hinge assembly is avoided, the occupied space is small after installation, and the structure is more compact; (4) the elastic buckling structure and the elastic rod 2 form a bidirectional elastic effect, so that the mounting efficiency is greatly improved, and the flexibility is high; (5) the whole structure is simple and compact, the production cost is low, and the market competitiveness of the product can be effectively improved under the condition of ensuring the whole strength and durability of the product.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
