Only when the locking piece 3 is slid to a position where it is disengaged from the pressing piece 4, the pressing piece 4 can be rotated relative to the female buckle component 1 to release the engagement with the male buckle component 2, so that the male buckle component 2 can be withdrawn from the female buckle component 1. The setting of the locking piece 3 can lock the pressing piece 4, indirectly limiting the male buckle component 2 from being disengaged from the female buckle component 1, effectively increasing the connection stability of the buckle in this embodiment.

[0044] Specifically, the female buckle assembly 1 includes a main body 11 and a cover plate 12, the cover plate 12 covers the main body 11 and forms a accommodating space with the main body 11, a first connecting portion 111 is provided on one side of the main body 11 for threading the webbing, and the male buckle assembly 2 includes a plug 21, a second connecting portion 23 is provided on one side of the plug 21, which is also used for threading the webbing, and the plug 21 is inserted into the accommodating space; a positioning column 113 is provided on the main body 11, and a rotating hole 44 is opened on the push member 4, the rotating hole 44 is sleeved on the positioning column 113, and the push member 4 is rotatably connected to the main body 11; a clamping portion 212 is provided on the plug 21, and the push member 4 includes a limiting portion 42. When the plug 21 is inserted into the accommodating space, the limiting portion 42 abuts against the clamping portion 212 for clamping the limiting plug 21. The user presses the push member 4 to control the push member 4 to rotate around the positioning column 113, so that the limiting portion 42 and the engaging portion 212 move away from each other, that is, the push member 4 and the plug 21 are disengaged, so that the male buckle component 2 and the female buckle component 1 can be disconnected. The locking member 3 is slidably arranged on the body 11. When the locking member 3 slides to abut against the push member 4, the push member 4 is locked by the locking member 3 and cannot move relative to the body 11. At this time, the push member 4 and the plug 21 cannot be disengaged. With this arrangement, even if the user accidentally touches the push member 4, the male buckle component 2 and the female buckle component 1 will not be disconnected, and the locking function of the plug buckle will not be affected.

[0045] For further information, see Figure 6The locking member 3 includes an integrally formed sliding portion 31 and a stop portion 32. When the locking member 3 is installed on the main body 11, the sliding portion 31 protrudes from the main body 11, which is convenient for user operation. The stop portion 32 is located in the accommodating space formed by the main body 11 and the cover plate 12, and is used to abut the pressing member 4. A plurality of positioning holes 112 are provided on the main body 11 along the plug-in direction of the male buckle component 2 and the female buckle component 1, and a plurality of positioning protrusions 33 are provided at corresponding positions on the stop portion 32 of the locking member 3, and the number of the positioning protrusions 33 is less than the number of the positioning holes 112; the locking member 3 can move along the arrangement direction of the positioning holes 112, and the positioning protrusions 33 are engaged and connected to the positioning holes 112. Specifically, in the present embodiment, the number of the positioning holes 112 is configured to be 3. Figure 6 From left to right along the center are positioning hole 112(a), positioning hole 112(b) and positioning hole 112(c), and the number of positioning protrusions 33 is configured to be two, namely positioning protrusion 33(a) and positioning protrusion 33(b). The shape and size of positioning protrusion 33 match the positioning hole 112. Please refer to Figure 7 and Figure 8 , Figure 7 The positioning protrusion 33(a) of the middle locking member 3 is snap-connected to the positioning hole 112(b), and the positioning protrusion 33(b) is snap-connected to the positioning hole 112(c). This position is defined as the first limit position of the locking member 3 in the female buckle assembly 1. At this time, the locking member 3 abuts against the push member 4, and the locking push member 4 rotates. Figure 4 and Fig. 9 The status shown, Fig. 9 It can be seen that, because the locking member 3 is in close contact with the pressing member 4, the pressing member 4 cannot rotate in the direction of the arrow in the figure, that is, when the plug 21 is inserted into the accommodating space and the locking member 3 is in the first limit position, the pressing member 4 cannot rotate relative to the female buckle component 1. At this time, the pressing member 4 and the plug 21 cannot be disengaged. Even if the user accidentally touches the pressing member 4, the male buckle component 2 and the female buckle component 1 will not be disconnected, and the locking function of the plug buckle will not be affected; Figure 8 The positioning protrusion 33(a) of the middle locking member 3 is snap-connected to the positioning hole 112(a), and the positioning protrusion 33(b) is snap-connected to the positioning hole 112(b). This position is defined as the second limit position of the locking member 3 in the female buckle assembly 1. At this time, the locking member 3 is separated from the push member 4, and the push member 4 can rotate relative to the female buckle assembly 1. Figure 5 Status shown.

Figure 1 and Figure 2As shown, in this embodiment, the guide groove 121 is provided on the cover plate 12, and the guide pin 22 is provided on the plug 21. The provision of the guide pin 22 and the guide groove 121 can not only facilitate the plug-in cooperation between the male buckle component 2 and the female buckle component 1, but also maintain the connection stability of the male buckle component 2 and the female buckle component 1 after being connected, and prevent the male buckle component 2 from shaking toward the locking member 3.

[0047] It can be understood that the push member 4 can be configured as one or a pair. If the push member 4 is configured as one, the plug 21 can only be limited on one side. However, due to the setting of the guide pin 22 and the guide groove 121, the plug 21 is also limited by the guide pin 22 and the guide groove 121, so that the position of the male buckle component 2 in the accommodating space is stable and will not be offset. In this embodiment, in order to further enhance the connection stability of the plug 21 in the accommodating space, the push member 4 is configured as a pair and is located on both sides of the body 11; the locking member 3 can also be configured as one or a pair. If it is configured as a pair, it is necessary to be respectively arranged on both sides of the body 11 corresponding to the position of the push member 4. When locking the push member 4, two locking members 3 can be slid respectively. In order to simplify the operation, in this embodiment, the number of locking members 3 is configured as one. When one push member 4 is locked on one side, even if the push member 4 on the other side can rotate relative to the body 11, the plug 21 cannot be disengaged from the push member 4 on the other side. This arrangement is not only convenient to operate, but also saves processing costs.

[0048] Furthermore, Figure 3 As shown, the push member 4 includes a push portion 41 and a limiting portion 42.

The limiting groove 34 is used to allow the reset member 5 to pass through the limiting groove 34 and abut against the inner wall of the body 11, and the position of the reset member 5 is maintained fixed; a stopper surface 321 is also provided on one side of the stopper 32, and the stopper surface 321 is used to abut against the engaging surface 43 of the pressing portion 41, as shown in FIG. Figure 4 As shown, when the locking member 3 is located at the first extreme position, the stop surface 321 abuts against the engaging surface 43 .

[0050] Further, such as Figure 2 and Fig.10 As shown, the plug 21 is provided with an integrally formed arc-shaped pushing portion 211 and a locking portion 212. When the locking member 3 is at the second limit position, the pushing portion 211 is used to push the limiting portion 42 of the pressing member 4 when the plug 21 is inserted into the accommodating space, so that the pressing members 4 on both sides of the plug 21 move along the Fig. 9 When the push part 211 is not in contact with the limit part 42 under the action of the reset part 5, the push part 4 moves toward Fig. 9 The limit portion 42 abuts against the engaging portion 212 of the plug 21 by rotating in the reverse direction of the arrow in the middle, so that the plug 21 and the push member 4 are engaged and connected. Figure 5 For details, please refer to Fig. 9 and Fig.10 , define the maximum dimension on both sides of the pushing portion 211 as D1, the minimum dimension on both sides of the locking portion 212 as D2, and the spacing between the limiting portions 42 of the pressing members 4 on both sides as D3, wherein D1>D3>D2.
