The quick-install fastening connection includes:

the first body 1, the first body 1 has a hollow core part 11 extending from the edge to the inner recess, the extending direction of the hollow core part 11 can be perpendicular to the plane of the edge of the first body 1, so that the hollow core part 11 can gradually enter the inside of the first body 1 in the extending direction. The hollow core 11 may include a plurality of core units 111 arranged at intervals, the core units 111 may have receiving units 1111 perpendicular to the extending direction of the hollow core 11, and each portion of the receiving units 1111 has a depth difference perpendicular to the extending direction of the hollow core 11, so that the receiving units 1111 may limit the elastic units 22 after the elastic units 22 extend into the receiving units 1111. Preferably, the hollow core 11 is a blind hole. Of course, in other alternative embodiments, the hollow core 11 may be a through hole. The receiving unit 1111 may have the shape of the embodiment shown in fig. 5 to 9.

The second body 2, the second body 2 may include a first flange 21 and an elastic unit 22 disposed at one end of the first flange 21, the elastic unit 22 may extend into the through hole of the second plate 4 and into the hollow core 11, and since the hollow core 11 includes a receiving unit 1111 with a depth difference therein, the elastic unit 22 may extend into the receiving unit 1111 under an elastic effect, so that the hollow core 11 and the elastic unit 22 perform a fastening function, and thus the first body 1 and the second body 2 perform a fastening function.

In this embodiment, through holes are formed in both the first plate 3 and the second plate 4, the first body 1 passes through the through hole in the first plate 3 and is fixed to the first plate 3, then the elastic unit 22 extends into the through hole in the second plate 4 and then extends into the hollow core 11, after the elastic unit 22 extends into the hollow core 11, the elastic unit can extend into the accommodating unit 1111 under the action of elastic force, so as to limit the relative movement of the first body 1 and the second body 2 in the extending direction of the hollow core 11. So that the second plate 4 is fixed between the first body 1 and the first flange portion 21 of the second body 2 to achieve the effect of tightly connecting the first plate 3 and the second plate 4.

By means of the structure, through the matching of the elastic unit 22 and the accommodating unit 1111, after the elastic unit 22 extends into the hollow core 11, part of the elastic unit 22 can enter the accommodating unit 1111 under the elastic action, and the depth difference of each part in the accommodating unit 1111 can enable a shallow position to realize the clamping effect on the elastic unit 22, so that the relative movement of the first main body 1 and the second main body 2 in the extending direction of the hollow core 11 is limited, the locking connection effect is realized, the whole locking connection process is quicker, the time required by the locking connection process is saved, and the installation efficiency is improved.

Specifically, the elastic unit 22 includes a plurality of elastic pins 221, one end of the elastic pin 221, which is close to the first flange portion 21, may be connected to the first flange portion 21, and one end of each elastic pin 221, which is close to the first flange portion 21, may have an elastic tendency that the elastic pins 221 are away from each other, so that in a natural state, the elastic pins 221 may be away from each other, and after being subjected to a force that causes the elastic pins 221 to approach each other, the elastic pins 221 may approach each other, thereby ensuring that the elastic pins may extend into the hollow portion 11. The elastic pins 221 may have an arc-shaped surface 2211 that is arched outward, where outward refers to a direction that causes the respective elastic pins 221 to move away. The arc-shaped surface 2211 is arranged, after the elastic pins 221 extend into the hollow portion 11, the arc-shaped surface 2211 can partially extend into the accommodating unit 1111, and because each part of the accommodating unit 1111 has a depth difference in a direction perpendicular to the extending direction of the hollow portion 11, the arc-shaped surface 2211 can be accommodated at a deeper position, and a clamping effect can be achieved on the arc-shaped surface 2211 at a shallower position, so that acting force required when relative movement occurs between the hollow portion 11 and the elastic pins 221 is increased, and a clamping effect is better achieved.

The transition portion 114 may transition the elastic unit 22, thereby transitioning the elastic unit 22 from an edge position of the first body 1 into the core unit 111, so that the elastic unit 22 is more effectively matched with the first body 1.

Specifically, the extending direction of the first body 1 is the same as the extending direction of the hollow portion 11, and the hollow portion 11 is located on the central axis of the first body 1, so that the hollow portion 11 and the elastic unit 22 can be fastened to prevent the first body 1 and the second body 2 from being misaligned.

Specifically, the first main body 1 may include a body and a second flange 12 located at an end of the body, one end of the body adjacent to the second flange 12 has an inwardly recessed press riveting portion 13, and the first plate 3 and the body are press riveted to the press riveting portion 13. So that the first sheet 3 can be connected to the body by means of clinching. The existence of the second flange part 12 can limit the first plate 3, so that the body and the first plate 3 are better in connection effect.

Specifically, the mold unit (not shown in the drawings) is provided with an abutting surface abutting against one end of the plurality of first flange portions 21 away from the elastic unit 22, so that the plurality of second bodies 2 are fixedly connected with the corresponding first bodies 1. The existence of the die unit can simultaneously fasten a plurality of second bodies to the corresponding first main body 1, thereby improving the working efficiency when fastening a plurality of second plates 4.

Specifically, the second body 2 includes a mating pin 23 located at an end of the first flange 21 away from the elastic unit 22, and an extending direction of the mating pin 23 is perpendicular to a plane where the first flange 21 is located.
