Description

Technical Field

[0001] The present invention relates to a buckle connector, and in particular to a buckle connector for use with a mask and a headgear. The buckle connector comprises a buckle plug and a buckle socket. The buckle plug is connectable to a headgear, and the buckle socket is disposed on a mask. When the buckle plug and the buckle socket are assembled, the headgear can be connected to the mask. When the buckle plug is detached from the buckle socket, the headgear is separated from the mask. Background Art

[0002] The prior art, such as the early public patent No. US20170021123 of the United States (its patent family includes the invention patent No. I614039 of Taiwan, China), mainly discloses a breathing mask, comprising a support frame (2), a soft mask cushion (3), an airway tube (4), and a pair of connectors (5). The support frame (2) has a pair of clamping parts (25), and each connector (5) can be clamped in each clamping part (25). The breathing mask can be worn on the patient's head using a headband (6), which is arranged on the connector (5) and is installed on the support frame (2) through the connector (5). When the connector (5) is detached from the support frame (2), the headband (6) is separated from the breathing mask. However, the connecting member (5) is a plastic fastener that can be elastically engaged. When the connecting member (5) is separated from the support frame (2), the connecting member (5) may hook the headband (6) and cause entanglement. In addition, when the connecting member (5) is separated from the support frame (2), the connecting members (5) may also hook each other. Therefore, there is still a need for improvement in the conventional technology. Summary of the Invention

[0003] In response to the defects of the above-mentioned prior art and the need for improvement, the present invention aims to provide a buckle connector for a mask and a headband, comprising a buckle plug and a buckle socket; the buckle plug has a base and a protective cover, an elastic arm extends from each side edge of the base, and a front end of each elastic arm has a hook, and the protective cover is arranged on the base; the buckle socket has a plug hole, and the buckle socket is integrally formed on a mask; wherein a horizontal plate of the protective cover covers the upper surface of the hook, a pair of longitudinal pieces of the protective cover cover the outer side surface of the hook, and the elastic arm is exposed from the longitudinal piece; when the buckle plug is combined with the buckle socket, the hook is fixed to the plug hole, and the horizontal plate and the longitudinal piece are located on the outside of the buckle socket; when the elastic arm is pressed, the hook can be separated from the plug hole.

[0004] The first beneficial effect of the present invention is that when a buckle plug is detached from a buckle socket, the structural features of the buckle plug can prevent the headband from being hooked on the hook and causing entanglement.

[0005] The second beneficial effect of the present invention is that when a pair of buckle plugs of a headband are detached from a pair of buckle sockets of a mask, the structural features of the buckle plugs can prevent the two buckle plugs from hooking with each other.

[0006] The third beneficial effect of the present invention is that when a buckle plug is combined with a buckle socket, the protective cover of the buckle plug can protect the buckle socket, a transverse plate of the protective cover shields a transverse wall of the buckle socket, and a pair of longitudinal pieces of the protective cover shield a pair of longitudinal walls of the buckle socket, thereby achieving anti-fouling and dust-proof effects.

[0021] Please refer to Figures 4 to 8, which list the combination methods of the buckle plug 10 and the buckle socket 20: the base 11 has a protrusion 17, which is located in the middle of the hook 14, and the hook 14 forms a first gap g1 on both sides of the protrusion 17 (as shown in Figure 8), and the longitudinal piece 16 and the hook 14 form a second gap g2 (as shown in Figure 8); when the buckle plug 10 is combined with the buckle socket 20, the hook 14 enters the plug hole 22, and the hook 14 moves through the first gap g1, causing the longitudinal wall 26 to penetrate the second gap g2 until each hook 14 hooks each positioning portion 24 (as shown in Figure 4).

[0022] Please refer to Figures 5, 6, 9 and 11, which list the auxiliary combination methods of the buckle plug 10 and the buckle socket 20: the base 11 has a protrusion 17, which is located in the middle of the hook 14, and a third gap g3 is formed between the transverse plate 15 and an upper surface 171 of the protrusion 17 (as shown in Figure 11); when the buckle plug 10 is combined with the buckle socket 20, the protrusion 17 enters the plug hole 22, and the transverse wall 25 penetrates the third gap g3, and the transverse plate 15 and the protrusion 17 assist in limiting the movement of the buckle plug 10 in the axial direction Z (as shown in Figure 5).

[0023] Please refer to Figures 7 to 12, which list the combination of the base 11 and the protective cover 12: the transverse plate 15 has an extension plate 151, and the extension plate 151 has a polygonal fixing column 18. The polygonal fixing column 18 is embedded or adhered to a polygonal fixing hole 152 of the base 11 to prevent the base 11 and the protective cover 12 from rotating relative to each other; wherein the base 11 has a through hole 19 to pass a headband 40.

[0024] Please refer to Figure 9, which lists the structural reinforcement methods of the buckle plug 10: the upper surface 141 of the hook 14 is lower than the upper surface 131 of the elastic arm 13 to increase the height and strength of the elastic arm 13; the upper surface 171 of the protrusion 17 is lower than the upper surface 111 of the base 11 to increase the height and strength of the base 11.

[0025] The embodiment of the mask body 30 is described below: the mask body 30 has a pair of buckle sockets 20 to combine with a pair of buckle plugs 10 on the headband 40; the preferred material of the mask body 30 can be selected from transparent materials.

[0027] The material of the base 11 is listed and described: the preferred material of the base 11 can be selected from opaque material, translucent material or transparent material, such as but not limited to opaque plastic material, translucent plastic material or transparent plastic material.

[0028] The functions of the protective cover 12 are as follows: when the buckle plug 10 is detached from the buckle socket 20, the buckle plug 10 uses the protective cover 12 to protect the hook 14, thereby preventing the headband 40 from hooking on the hook 14 and causing entanglement. Furthermore, when the pair of buckle plugs 10 of the headband 40 are detached from the pair of buckle sockets 20 of the mask body 30, the buckle plugs 10 can use the protective cover 12 to prevent the two buckle plugs 10 from hooking on each other. Furthermore, when the buckle plug 10 is assembled with the buckle socket 20, the protective cover 12 of the buckle plug 10 protects the buckle socket 20. The transverse plate 15 of the protective cover 12 can cover the transverse wall 25 of the buckle socket 20, and the pair of longitudinal pieces 16 of the protective cover 12 can cover the pair of longitudinal walls 26 of the buckle socket 20, thereby achieving anti-fouling and dustproof effects.

[0029] The second embodiment of the present invention is described below: The second embodiment of the present invention is substantially the same as the preferred embodiment, except that the protective cover 12 is molded on the base 11 by insert molding. The insert molding method is performed under conditions such that a pair of longitudinal pieces 16 of the protective cover 12 and a pair of hooks 14 of the protective cover 12 maintain an appropriate distance from each other, and a pair of longitudinal pieces 16 of the protective cover 12 and a pair of elastic arms 13 of the base 11 also maintain an appropriate distance from each other.
