[ detailed description ] of the utility model

For a better understanding of the utility model with objects, structures, features, and effects, the utility model will be described further with reference to the drawings and to the detailed description.

As shown in fig. 1 to 36, eight embodiments of the anti-loss cord according to the present utility model are provided for connection to at least one wireless ear-use audio device 7, by which the anti-loss cord is connected to clothing on the user's body, or to the user's earlobe, or to the user's neck, or to the user's wrist, to prevent the wireless ear-use audio device 7 from being lost directly when it is dropped from the user's ear, or when it is not in use.

As shown in fig. 2, 8, 10, 15, 17, 23, 27 and 32, the wireless ear audio device 7 includes an ear plug portion 71 inserted into the ear of the user and an ear stem 72 exposed outside the ear of the user. The ear stem 72 is configured to be coupled to the anti-lost rope. In the first to eighth embodiments, the ear stem 72 is cylindrically provided for connection with the anti-loss cord. In other embodiments, the ear 72 is provided in a rectangular body.

As shown in fig. 1, 7, 9, 14, 16, 21, 26 and 31, the anti-lost rope of the present utility model comprises at least one socket 1 and a connecting wire 2 connected with the socket 1 in a longitudinal direction. Wherein the socket 1 is directly or indirectly connected to one end of the connection wire 2, the socket 1 is configured to be sleeved outside the ear stem 72 of the wireless ear audio device 7 (see fig. 2, 8, 10, 15, 17, 23, 27 and 33 for details), and the other end of the connection wire 2 is connected to an element, so that it is known that the connection wire 2 is configured to interconnect the wireless ear audio device 7 and the element.

As shown in fig. 1, 7, 9, 14, 16, 21, 26 and 31, the socket 1 of the present utility model includes a flexible sleeve 11 and an elastic thread 12 extending along the length of the flexible sleeve 11 and passing through the flexible sleeve 11, wherein the elastic thread 12 is used for directly or indirectly connecting with the connecting wire 2. The length of the elastic wire 12 is greater than the length of the soft sleeve 11, and the soft sleeve 11 can be displaced along the length extension direction of the elastic wire 12. The flexible sleeve 11 includes two ends 111 at two ends of the flexible sleeve 11 in the length extending direction, and a through hole 112 inside the flexible sleeve 11 and extending along the length extending direction of the flexible sleeve 11, wherein the through hole 112 allows the elastic wire 12 to pass through. The elastic thread 12 has a receiving section 121 received in the through hole 112 and a exposing section 122 connected to two ends of the receiving section 121, that is, the exposing section 122 is exposed outside the flexible sleeve 11, and the exposing section 122 and the receiving section 121 are connected end to form a closed coil structure, in other words, the elastic thread 12 is the coil structure surrounded by the exposing section 122 and the receiving section 121, the portion of the elastic thread 12 received in the through hole 112 is defined as the receiving section 121, and the portion of the elastic thread 12 protruding out of the flexible sleeve 11 is defined as the exposing section 122. Because the coil structure formed by surrounding the exposing section 122 and the accommodating section 121, the flexible sleeve 11 sleeved outside the accommodating section 121 and the exposing section 122 surround to form an accommodating space 13, the accommodating space 13 is used for accommodating the ear stem 72, so that the socket joint member 1 is sleeved on the ear stem 72, and the exposing section 122 is directly or indirectly connected with the connecting wire 2.

As shown in fig. 2, 8, 10, 15, 17, 23, 27 and 32, the soft sleeve 11 of the present utility model is used to surround the ear stem 72 and directly contact the surface of the ear stem 72, and the softness of the soft sleeve 11 is such that the soft sleeve 11 does not damage the surface of the ear stem 72 in contact therewith. The elastic wire 12 passes through the soft sleeve 11, so that the soft sleeve 11 is correspondingly deformed according to the length extension direction of the elastic wire 12, and the soft sleeve 11 is attached to the surface of the ear stem 72 due to the elasticity of the elastic wire 12, and similarly, the elastic wire 12 is also arranged around the ear stem 72, and the sleeve joint piece 1 can be sleeved outside the ear stem 72 with different circumferences by using the elasticity of the elastic wire 12, so as to improve the adaptability of the anti-lost rope. When the ear stem 72 is not inserted into the accommodating space 13, the accommodating space 13 is irregularly arranged, and when the ear stem 72 is inserted into the accommodating space 13, the accommodating space 13 is stretched from the original irregular shape to a shape adapted to the outer peripheral surface of the ear stem 72 by the elasticity of the elastic wire 12, so as to sleeve the socket 1 on the wireless ear audio device 7 (see fig. 4 in detail).

As shown in fig. 2, 8, 10, 15, 17, 23, 27 and 32, the flexible sleeve 11 of the present utility model is attached to the outer surface of the ear stem 72 due to the elasticity of the elastic wire 12, so that the flexible sleeve 11 is sleeved on the ear stem 72 from bottom to top, and the flexible sleeve 11 rolls around the length extending direction, but since the flexible sleeve 11 and the elastic wire 12 are separately arranged, the flexible sleeve 11 can roll around the elastic wire 12, the elastic wire 12 is not easy to roll along with the flexible sleeve 11 sleeved outside, and the connecting wire 2 directly or indirectly connected with the elastic wire 12 is prevented from rolling into the accommodating space 13, thereby causing the winding and knotting between the connecting wire 2 and the elastic wire 12.

As shown in fig. 1, 7, 9, 14, 16, 21, 26 and 31, in the first to eighth embodiments, the flexible sleeve 11 has elasticity, can be contracted to some extent along its length extension direction, and has elasticity smaller than that of the elastic wire 12, and of course, the flexible sleeve 11 also has elasticity to some extent in a cross-section direction perpendicular to its length direction. In other embodiments, the flexible sleeve 11 may not have elasticity.

As shown in fig. 3, 4, 8, 11, 12, 15, 18, 23, 28 and 34, the length of the flexible sleeve 11 of the present utility model is not less than half the circumference of the ear stem 72. In the first to eighth embodiments, the length of the flexible sleeve 11 of the present utility model is greater than half the circumference of the ear stem 72, specifically, the length of the flexible sleeve 11 is 20mm to 22mm, which is relatively suitable for the ear stem 72 of the wireless ear audio device 7 currently on the market.

As shown in fig. 1, 7, 9, 14, 16, 21, 26 and 31, in the first to eighth embodiments, the elastic thread 12 is an elastic thread, and the elastic thread is formed by double-coating high-quality double-strand fiber filaments (polyester filaments or nylon filaments, also called terdolon filaments or nylon filaments) with an inlet elastic yarn as a core.

As shown in fig. 1, 7, 9, 14, 16, 21, 26 and 31, in the first to eighth embodiments, the connection wire 2 has elasticity to play a role of buffering when the wireless ear audio device 7 falls from the ear of the user, so as to avoid injury to the ear of the user when the wireless ear audio device 7 is pulled strongly and reduce pain caused by the injury, and also avoid damage caused by the wireless ear audio device 7 falling directly onto other objects due to gravity.

As shown in FIG. 5, the ear stem 72 is arranged in a circular ring shape on a cross section perpendicular to the length extension direction of the flexible sleeve 11, the inner diameter of the circular ring is 1mm, and the outer diameter of the circular ring is not more than 2mm. Since the cross section of the flexible sleeve 11 perpendicular to the length extending direction thereof is circular, it is known that the cross section of the through hole 112 perpendicular to the length extending direction of the flexible sleeve 11 is circular, and the diameter of the through hole 112 is consistent along the length extending direction of the flexible sleeve 11, that is, the through hole 112 is a circular through hole 112 with the diameter unchanged along the length extending direction of the flexible sleeve 11, wherein the diameter of the through hole 112 is 1mm, the cross section of the elastic wire 12 perpendicular to the length extending direction of the elastic wire 12 is circular, the cross section of the elastic wire 12 is consistent along the length extending direction of the elastic wire 12, and the diameter of the circular cross section of the elastic wire 12 is less than 1mm, so that the elastic wire 12 is accommodated in the through hole 112, and the flexible sleeve 11 can be displaced along the length extending direction of the elastic wire 12. The structure of the flexible sleeve 11 and the structure of the elastic wire 12 can be used in the first to eighth embodiments of the present utility model.

In another embodiment, as shown in fig. 6, the cross section of the through hole 112 perpendicular to the length extension direction of the flexible sleeve 11 is different from the cross section of the elastic thread 12 perpendicular to the length extension direction of the elastic thread 12. Specifically, in other embodiments, the cross section of the through hole 112 in the direction perpendicular to the length extension direction of the flexible sleeve 11 is circular, and the cross section of the through hole 112 is uniform along the length extension direction of the flexible sleeve 11, that is, the through hole 112 is a circular through hole 112 with a constant diameter along the length extension direction of the flexible sleeve 11, wherein the diameter of the through hole 112 is 1mm, the cross section of the elastic thread 12 in the direction perpendicular to the length extension direction of the elastic thread 12 is rectangular, specifically rectangular, and the cross section of the elastic thread 12 is also uniform along the length extension direction of the elastic thread 12, specifically, the long side of the rectangular cross section of the elastic thread 12 is 0.9mm, and the short side is 0.6mm. In this embodiment, the rectangular cross section of the elastic thread 12 is in plane contact with the outer surface of the ear stem 72, so that the elastic thread 12 with the rectangular cross section is less likely to roll along with the soft sleeve 11 provided with the circular through hole 112. The structure of the flexible sleeve 11 and the structure of the elastic thread 12 can be used in all embodiments of the utility model.
