Embodiment 1

[0033] Such as Figure 1-3 As shown, a fastening structure of this embodiment includes a slot 3 and a buckle foot 5 cooperating with the slot 3, wherein a blocking portion 4 is provided on the side wall of the slot 3; A protrusion 6 is provided on the side wall of the buckle foot 5 facing the blocking portion 4, and the blocking portion 4 prevents the buckle foot 5 from inserting into or withdrawing from the slot by blocking the protrusion 6 3. The protruding part 6 is elastically and telescopically arranged on the buckle pin 5, or the blocking part 4 is elastically and telescopically arranged on the side wall of the card slot 3, and the protruding part 6 and the shape of the collision part of the blocking part 4 are mutually matched and satisfied. The conflicting position of the position against the blocking portion 4 elastically retracts the protrusion 6 or the blocking portion 4 until the protrusion 6 can pass through.

[0034] The above-mentioned solution is the core sol...

Embodiment 2

[0044] Such as Figure 4 As shown, in this embodiment, an installation hole is formed on the buckle foot 5, and the protrusion 6 is installed in the installation hole, and there is a gap between the protrusion 6 and the installation hole. A second biasing member is provided, and the biasing force of the second biasing member acts on the raised portion 6 to make the contact portion of the raised portion 6 protrude out of the installation hole. Preferably, the second biasing member is a compression spring 7 .

[0045] Embodiments 1 and 2 are the schemes in which only one protrusion 6 is provided on the buckle foot 5, and a blocking portion 4 is provided on the side wall of the slot 3; The protruding portion 6 and the two opposite side walls of the card slot 3 are respectively provided with a blocking portion 4 .

Abstract

The invention relates to a fastening structure and a protective case with the fastening structure, wherein the fastening structure includes a slot and a buckle foot cooperating with the slot, wherein a blocking portion is provided on the side wall of the slot; A protrusion is provided on the side wall of the buckle foot facing the blocking portion, and the blocking portion prevents the buckle foot from inserting into or withdrawing from the card slot through the blocking protrusion; the protrusion is elastically and telescopically arranged on the buckle foot, or blocks The part is elastically and stretchably arranged on the side wall of the card slot, and the shapes of the contact parts of the protruding part and the contact part of the blocking part match and satisfy each other. The conflicting part of the part collides with the conflicting part of the blocking part to elastically retract the protruding part or the blocking part until the protruding part can pass through. The fastening structure of the present invention and the protective case with the fastening structure are simple and convenient to assemble and disassemble, have good operation feel and long service life.

Description

technical field [0001] The invention relates to the field of connecting structures, in particular to a fastening structure and a protective case with the fastening structure. Background technique [0002] The mobile phone is an essential tool in people's life. In order to prevent the mobile phone from being damaged by falling or colliding, a mobile phone protective case is usually used to protect the mobile phone. In order to ensure that the mobile phone can be easily installed and disassembled, in the existing mobile phone protective case, the mobile phone protective case is usually set as two separate parts, and then the two separate parts are connected into one through a detachable connection structure, such as China Patent document CN203661131U discloses a protective case for a mobile phone. The protective case for a mobile phone is composed of a detachable upper case and a lower case. The side wall is provided with a curved portion hooked to the protrusion, and the clo...
