[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention.

[0038] The jack of the existing connection buckle usually has only one opening. When the male buckle is inserted into and disengaged from the jack for locking and unlocking, it can only move unidirectionally from the opening respectively, resulting in the problems of low degree of freedom of operation and inconvenient use.

[0039] To solve the above technical problems, this embodiment provides a quick-release connection structure for accessories. Please refer to Figures 1 to 5 as shown in Figure 1 FIG. Figure 2 is a perspective view of the quick-release connection structure for accessories in the embodiment; Figure 3 FIG. Figure 4 is an exploded view of the quick-release connection structure for accessories in the embodiment; Figure 3 FIG. Figure 5 is a top view of the quick-release connection structure for accessories in the embodiment;

[0040] A quick-release connection structure for accessories according to this embodiment, as shown in Figure 2 includes: a female buckle 1, a pressing member 2, an elastic member 3, and a male buckle 4.

[0041] The female buckle 1 is provided with a connection channel 10 penetrating along a straight line direction, and a sliding groove 11 communicating with the connection channel 10. The connection channel 10 is used to connect the male buckle 4, and the sliding groove 11 is used to install the pressing member 2.

[0042] As shown in Figure 4 the pressing member 2 includes a slider 21, a positioning block 22 connected to the slider 21, and a button 23 exposed outside the female buckle 1. The slider 21 is slidably disposed in the sliding groove 11, and the positioning block 22 is used to lock the male buckle 4.

[0043] As shown in Figure 4 the elastic member 3 is disposed between the pressing member 2 and the female buckle 1 and is used to provide an elastic force for the pressing member 2 to reset.

[0044] The male buckle 4 can be inserted into the connection channel 10 and slide therein along a straight line direction, so that the male buckle 4 and the female buckle 1 are relatively fixed in the cross-sectional direction of the connection channel 10, that is, there is only a degree of freedom of relative movement along the straight line direction. The male buckle 4 is provided with a positioning groove 41 adapted to the positioning block 22.

[0045] Among them, as shown in Figure 4 when the female buckle 1 and the male buckle 4 are in a locked state, the male buckle 4 is inserted into the connection channel 10, the positioning block 22 and the positioning groove 41 are in opposite positions, and under the drive of the elastic member 3, it extends into the positioning groove 41, so that the female buckle 1 and the male buckle 4 are relatively fixed; when pressing the button 23, the button 23 drives the positioning block 22 to move along the sliding groove 11 through the slider 21 until the positioning block 22 disengages from the positioning groove 41 or the connection channel 10, so that the male buckle 4 can be disengaged from or inserted into the connection channel 10 along a straight line direction.

[0046] When performing the locking operation on the quick-release connection structure of the fitting in the above technical solution, the male buckle 4 is inserted into the connection channel 10 along a straight line direction to a preset position. The positioning block 22 is opposite to the positioning groove 41 in position and extends into the positioning groove 41 under the drive of the elastic member 3, so that the female buckle 1 and the male buckle 4 are relatively fixed. When performing the unlocking operation, the user presses the button 23, and the button 23 drives the positioning block 22 to move along the sliding groove 11 through the slider 21 until the positioning block 22 disengages from the positioning groove 41. Subsequently, the male buckle 4 is disengaged from the connection channel 10 along a straight line direction to achieve unlocking. It can be seen that the female buckle 1 in the above technical solution cooperates with the male buckle 4 through the connection channel 10 penetrating along a straight line direction, enabling the male buckle 4 to be inserted into and disengaged from the connection channel 10 from either end of the connection channel 10, having two degrees of freedom of operation. Compared with the traditional male buckle 4 and female buckle 1 with one-way cooperation, the degrees of freedom of locking and unlocking operations are increased, and it is more convenient to use.

[0047] In an implementation manner where the above male buckle 4 and female buckle 1 are relatively fixed in the cross-sectional direction of the connection channel 10, referring to Figure 2 and Figure 4 as shown, the connection channel 10 is provided with a relief opening 101, and a limiting portion 12 extending inward is provided at the relief opening 101. The male buckle 4 is provided with a limiting groove 42 adapted to the limiting portion 12. When the female buckle 1 and the male buckle 4 are in a locked state, the limiting portion 12 is inserted into the limiting groove 42 so that the male buckle 4 and the female buckle 1 are relatively fixed in the cross-sectional direction of the connection channel 10. Among them, part of the male buckle 4 can be located inside the connection channel 10 and part can be located outside the connection channel 10 at the relief opening 101, without affecting the sliding of the male buckle 4 on the connection channel 10.

[0048] Exemplarily, referring to Figure 2 and Figure 4 as shown, the limiting portion 12 extends inward from the inner side of the relief opening 101, making the cross-section of the connection channel 10 in a dovetail shape, and the shape of the part of the male buckle 4 cooperating with the connection channel 10 is adapted to the connection channel 10, thereby being able to limit the male buckle 4 and the female buckle 1 to have only the degree of freedom of moving along the above straight line direction.

[0049] In an implementation manner of the above pressing member 2, referring to Figure 2 and Figure 4 as shown, the button 23 and the positioning block 22 are respectively connected to the opposite ends of the slider 21.

[0050] Exemplarily, the pressing member 2 is an integrally formed part.

[0051] Exemplarily, referring to Figure 4 as shown, the sliding groove 11 extends to the opposite sides of the connection channel 10. The extended part on one side is used to install the positioning block 22, and the extended part on the other side is used to install the connection part of the button 23 and the slider 21, and this connection part forms a stepped structure 24 for limiting with the button 23.

[0052] In an embodiment where the elastic member 3 is disposed between the pressing member 2 and the female buckle 1, referring to Figure 4 As shown, a positioning hole 201 is provided at one end of the positioning block 22 away from the slider 21. The extending direction of the positioning hole 201 is parallel to the sliding groove 11. One end of the elastic member 3 is disposed in the positioning hole 201, and the other end abuts against the female buckle 1. The positioning hole 201 serves as a stroke hole for the elastic deformation of the elastic member 3 and can also guide the elastic member 3.

[0053] Exemplarily, the elastic member 3 is a compression spring.

[0054] In other embodiments where the elastic member 3 is disposed between the pressing member 2 and the female buckle 1, the elastic member 3 can also be a tension spring and is connected between the pressing member 2 and the female buckle 1.

[0055] To reduce the protrusion of the key 23, referring to Figure 2 and Figure 4 As shown, the female buckle 1 is provided with a receiving groove 13 for the key 23. The receiving groove 13 communicates with the sliding groove 11. The receiving groove 13 can partially or completely receive the key 23, making the end face of the key 23 flush with the outer side surface of the female buckle 1 and improving the integrity of the product appearance.

[0056] Further, to limit the moving stroke of the pressing member 2, referring to Figure 2 and Figure 4 As shown, a stroke groove 102 extending along the direction of the sliding groove 11 is provided on the inner side of the receiving groove 13. The key 23 is provided with a stroke rod 202. The stroke rod 202 is slidably disposed in the stroke groove 102 to limit the moving stroke of the key 23 and prevent the key 23 from disengaging from the receiving groove 13 and the slider 21 from disengaging from the sliding groove 11.

[0057] Exemplarily, referring to Figure 4 As shown, the stroke rod 202 is a pin member inserted on the pressing member 2. The bottom of the female buckle 1 can be opened to expose one end of the stroke groove 102 away from the receiving groove 13. Thus, when installing the pin member, the pressing member 2 can be first engaged with the sliding groove 11 to make the key 23 located in the receiving groove 13, and then the above-mentioned pin member can be installed upward from the bottom of the receiving groove 13.

[0058] To improve the smoothness of insertion and detachment between the male buckle 4 and the female buckle 1, referring to Figure 2 and Figure 4 As shown, an arc chamfer 103 is provided at the corner of the connecting channel 10.

[0059] To facilitate the insertion of the male buckle 4 into the connecting channel 10, referring to Figure 2 and Figure 4As shown, the male buckle 4 is provided with guide slopes 43 at both ends of the direction of insertion into the connecting channel 10. With such a configuration, when the female buckle 1 is matched with the male buckle 4, the user does not need to press the button 23, that is, the button 23 is not required to drive the positioning block 22 to move along the slide groove 11 through the slider 21 to make the positioning block 22 detach from the connecting channel 10. The male buckle 4 only needs to be inserted into the connecting channel 10 along a straight line. When the guide slope 43 of the male buckle 4 contacts the positioning block 22, the positioning block 22 is pressed by the guide slope 43 due to the action of external force, and moves in the direction of compressing the elastic member 3 along one end of the slide groove 11, until the positioning block 22 is opposite to the positioning groove 41, and the positioning block 22 rebounds and extends into the positioning groove 41 under the drive of the elastic member 3, so that the female buckle 1 and the male buckle 4 are relatively fixed.

[0060] The male buckle 4 and the female buckle 1 are used to connect accessories, drawstrings and other components, for example, see Figure 4 As shown, the male buckle 4 is provided with a connecting ring 44 for connecting accessories, and the female buckle 1 is provided with a connecting hole 14 for connecting a drawstring.

[0061] In order to allow the male buckle 4 to be inserted into the connecting channel 10 through either end, see Figure 5 As shown, the male buckle 4 is a bilaterally symmetrical structure, and a positioning groove 41 is provided on each of the two opposite sides.

[0062] Although the embodiments of the present invention have been shown and described, it will be understood 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 the scope of the present invention is defined by the appended claims and their equivalents.
