[0020] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0021] Refer to the following Figure 1-Figure 4 A snap-on elastic connection structure according to some embodiments of the present application is described.

[0022] A buckle elastic connection structure comprises a fixing seat 1 and a guide buckle 2, wherein the guide buckle 2 comprises a clamping head 3 and a clamping body 4 connected to each other, wherein the clamping head 3 is a protrusion relative to the clamping body 4, and the width of the clamping head 3 is W1;

[0023] An opening 5 matching the guide buckle 2 is provided on the front of the fixing seat 1, a cavity is provided inside the fixing seat 1, a pair of elastic connecting components 6 are provided in the cavity, the elastic connecting components 6 are symmetrically arranged around the center of the opening 5, a bayonet 7 is formed between the elastic connecting components 6, and the width of the bayonet 7 is W2 and W2<W1.

[0024] The elastic connection component 6 includes a nail seat 8, a spring 9 and a nail 10. The side wall of the nail seat 8 facing the bayonet 7 is provided with a nail hole 11, and the side wall of the nail seat 8 on the other side opposite to the nail hole 11 is provided with a spring seat 12. The nail 10 is inserted into the nail hole 11, and the head of the nail 10 is exposed from the nail hole 11. The nail 10 is provided with an annular flange 13 on the nail body in the nail seat 8, and the outer edge of the annular flange 13 is larger than the nail hole 11. One end of the spring 9 is connected to the spring seat 12, and the other end of the spring 9 abuts against the annular flange 13.

[0025] When the guide buckle 2 is connected to the fixed seat 1, the clamping head 3 is inserted into the opening 5 of the guide seat. Since the width W2 of the bayonet 7 is less than the width W1 of the clamping head 3, when the clamping head 3 enters the bayonet 7, the two sides of the clamping head 3 push the spring nail 10 to retract to both sides to expand the width of the bayonet 7 until the clamping head 3 passes through. After the clamping head 3 passes, the spring nail 10 rebounds to the bayonet 7 with the width W2 under the action of the spring 9, thereby limiting the clamping head 3 and completing the connection between the guide buckle 2 and the fixed seat 1; when the guide buckle 2 needs to be removed from the fixed seat 1, the clamping head 3 is pulled outward, and the two sides of the clamping head 3 push the spring nail 10 to retract to both sides to expand the width of the bayonet 7 until the clamping head 3 passes through, thereby releasing the restriction on the clamping head 3 and completing the separation of the guide buckle 2 and the fixed seat 1.

[0026] In order to achieve the stability of the connection between the guide buckle 2 and the fixed seat 1, preferably, the width of the opening 5 should be slightly greater than or equal to the width W1 of the clamping head 3, and the length L of the spring nail 10 exposed from the spring nail hole 11 should be greater than (W1-W2) / 2, which can prevent the screw 10 from entering the spring seat 12 when retracting.

[0027] The clamp head 3 is at least one of a mushroom shape, a T shape, and a triangle shape, and the head of the elastic nail 10 is a spherical shape, so that the clamp head 3 can achieve effective action with the elastic nail 10 when passing through the bayonet 7.

[0028] Since the elastic connection component 6 is arranged on the fixed base 1, and the fixed base 1 is generally fixedly arranged at the position where the buckle is required, and the guide buckle 2 is connected to the fixed base 1 by the clamping head 3 entering and exiting the bayonet 7, the guide buckle 2 does not need a large external size, so the buckle elastic connection structure is suitable for installation and use in corners or inner grids with smaller internal spaces.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
