Fig. 11 is a schematic view of the device with magnetic buckle assembly according to the present invention. The device is used for improving sleep breathing obstruction, wherein the device comprises a mouth mechanism 200, a fixing mechanism 300 and the magnetic buckle assembly 100 in the first embodiment for fixedly connecting the mouth mechanism 200 and the fixing mechanism 300 together. In this embodiment, portions of the oral mechanism 200 are adapted to be inserted into the mouth of a user to ameliorate symptoms of sleep respiratory obstruction in the user. The fixing mechanism 300 is used to position the oral mechanism 200 at the oral cavity of the head of the user, in this embodiment, the fixing mechanism 300 is a head band, and the fixing mechanism 300 is sleeved outside the head of the user. In other embodiments, the fixing mechanism 300 can also be sleeved at the ear root of the head of the user to position the oral mechanism 200 at the oral cavity of the user. In this embodiment, the male buckle seat 10B of the magnetic buckle assembly 100 is used for being fixedly connected with the oral mechanism 200, the female buckle seat 10A of the magnetic buckle assembly 100 is used for being connected with the fixing mechanism 300, and the fixing mechanism 300 is wound on the rotating ring 3 of the female buckle seat 10A. Based on the convex column 19 and the rotary ring 3, it is also possible to only arrange the male buckle seat 10B, and it is also possible to fixedly connect the female buckle seat 10A with the mouth mechanism 200 at this time, and connect the rotary ring 3 on the male buckle seat 10B with the fixing mechanism 300. Specifically, the fixing mechanism 300 is configured to be connected to one of the male buckle seat 10B and the female buckle seat 10A provided with the convex column 19 and the rotary ring 3, and the mouth mechanism 200 is configured to be connected to the other of the male buckle seat 10B and the female buckle seat 10A not provided with the convex column 19 and the rotary ring 3.

As shown in fig. 12 to 14, in the second embodiment of the magnetic buckle assembly of the present invention, the difference between the magnetic buckle assembly 100 in the second embodiment and the magnetic buckle assembly 100 in the first embodiment is: the first inner side surface 13, the second inner side surface 18, the first outer side surface 55, and the second outer side surface 58 are flat surfaces extending in the up-down direction and the left-right direction, that is, projections of the first inner side surface 13, the second inner side surface 18, the first outer side surface 55, and the second outer side surface 58 on a horizontal plane are straight lines extending in the left-right direction, that is, the first inner side surface 13 and the second inner side surface 18 are perpendicular to the blocking portion 14, and the first outer side surface 55 and the second outer side surface 58 are perpendicular to the fitting portion 54. The first inner side surface 13 and the second inner side surface 18 have the same length in the left-right direction, and the first outer side surface 55 and the second outer side surface 58 have the same length in the left-right direction. In addition, the circle center of the neck 191, the circle center of the head 192, and the circle center of the magnetic element 2 are aligned in the up-down direction, that is, the circle center of the neck 191, the circle center of the head 192, and the circle center of the magnetic element 2 are located on the same straight line extending in the up-down direction, that is, the protruding column 19 is aligned with the magnetic element 2 in the front-back direction, and the first positioning hole 4 penetrates through the female buckle seat 10A and the magnetic element 2 along the straight line where the circle center of the neck 191, the circle center of the head 192, and the circle center of the magnetic element 2 are located.

The utility model has the advantages as follows:

1) because the female buckle seat 10A is provided with the blocking part 14, the male buckle seat 10B is provided with the matching part 54 matched with the blocking part 14, the blocking part 14 is matched with the matching part 54 to block the male buckle seat 10B from horizontally rotating relative to the female buckle seat 10A, so that the fixation of the relative position between the male buckle seat 10B and the female buckle seat 10A is ensured, the stability of combination between the male buckle seat 10B and the female buckle seat 10A is enhanced, and the tightness of combination between the mouth part mechanism 200 and the fixing mechanism 300 connected through the magnetic buckle assembly 100 is further ensured.

2) Because the rotating ring 3 can horizontally rotate on the horizontal plane around the convex column 19, two parts which are connected with each other through the magnetic buckle assembly 100 can relatively rotate, and the applicability of the magnetic buckle assembly 100 is enhanced.

3) The limiting surface 17 stops the male buckle seat 10B downward, and further prevents the male buckle seat 10B from being separated from the accommodating groove 11 toward the side away from the female buckle seat 10A.

4) The sliding surface 59 slides into the receiving groove 11 along the guiding surface 15, and it can be seen that the guiding surface 15 can guide the male buckle seat 10B to slide into the receiving groove 11, so that the operation convenience of installing the male buckle seat 10B into the female buckle seat 10A is enhanced.

5) The first inner side surface 13 and the second inner side surface 18 can be used for stopping the male buckle base 10B from being separated from the female buckle base 10A backwards, so that the matched positions of the male buckle base 10B and the female buckle base 10A in the front-back direction are limited, the magnetic element 2 and the magnetic element 6 can be aligned in the front-back direction, and the phenomenon that the binding force of the magnetic element 2 and the magnetic element 6 in the up-down direction is weakened is avoided.

6) The swivel 3 made of metal bar can be opened at the force application section 32, so that the fixing mechanism 300 can enter the inside of the swivel 3 from the opening of the force application section 32 to achieve connection with the swivel 3.

7) The male buckle seat 10B can slide forward and downward along the guide surface 15 into the receiving groove 11, and then move backward to receive the limiting block 56 into the limiting groove 16, and the male buckle seat 10B can also move backward along the receiving surface 12 from beginning to end along the front-back direction, so that the limiting block 56 is received into the limiting groove 16, which increases the operation mode of mounting the male buckle seat 10B into the female buckle seat 10A in two ways.

8) The length of the force application section 32 is greater than the diameter of the head 192, and the shortest straight distance between the end of the connection section 33 connected to the pivot connection section 31 and the force application section 32 is greater than the diameter of the head 192, so that the swivel 3 can be sleeved outside the boss 19 from bottom to top, and the swivel 3 can be pulled to sleeve the pivot connection section 31 outside the neck 191 at a later stage.

9) Since the fixing mechanism 300 is connected to the rotating ring 3, it can be seen that the fixing mechanism 300 can rotate relative to the magnetic buckle assembly 100 to adjust the fitting position between the fixing mechanism 300 and the head of the user, so that the oral mechanism 200 can be more accurately positioned at the oral cavity of the head of the user.

The above detailed description is only for the purpose of illustrating the preferred embodiments of the present invention, and not for the purpose of limiting the scope of the present invention, therefore, all the equivalent technical changes using the description and drawings of the present invention are included in the scope of the present invention.
