As shown in fig. 1-9, the utility model provides a simple mask fixing device, which comprises: the body 100, the adjusting mechanisms 200 distributed on the left and right sides of the body 100, and the connecting devices 300 distributed outside the adjusting mechanisms 200.

The adjustment mechanism 200 includes two sliders 210, an adjustment arm 220, a plurality of one-way sliding teeth 230, and a return torsion spring 240.

The two sliders 210 are respectively located at the upper and lower sides of the body 100 and slidably connected to the body 100. Specifically, the upper side and the lower side of the body 100 are provided with the sliding grooves 110, the sliding grooves 110 extend along the length direction of the body 100, and the two sliding blocks 210 are respectively connected with the body 100 in a sliding manner through the two sliding grooves 110, so that the sliding blocks 210 can be limited, and the movement of the sliding blocks can be guided.

The adjusting arm 220 is located between the two sliding blocks 210 and is rotatably connected with the two sliding blocks 210, and a limiting tooth 221 matched with the one-way sliding tooth 230 is arranged on one side of the adjusting arm 220 facing the central line of the body 100. Specifically, both sides of the middle portion of the adjusting arm 220 are rotatably connected to the two sliders 210, respectively, so that one side and the other side of the adjusting arm 220 are pressed and lifted.

A plurality of unidirectional sliding teeth 230 are sequentially distributed on the body 100 at intervals. Specifically, since the adjusting mechanisms 200 are installed on both the left and right sides of the body 100, the unidirectional sliding teeth 230 are naturally disposed on both the left and right sides of the body 100, and the limiting directions of the unidirectional sliding teeth 230 located on both the left and right sides of the body 100 are opposite.

The restoring torsion spring 240 is located between the sliding block 210 and the adjusting arm 220, and in a natural state, the restoring torsion spring 240 bears a torsion force to provide a stress for keeping the limit tooth 221 and the one-way sliding tooth 230 against each other.

The connecting means 300 is used to connect with the ear band 400 of the mask.

When the mask is used, in the wearing process, the ear belt 400 of the mask is connected with the connecting device 300, then the sliding block 210 is shifted towards the central line direction of the body 100, the limiting teeth 221 slip with the one-way sliding teeth 230, but under the action of the reset torsion spring 240, the limiting teeth 221 and the one-way sliding teeth 230 are always kept in contact. When the mask is adjusted to a proper position, the sliding block 210 stops being stirred, and the position of the adjusting mechanism 200 on the body 100 can be locked under the action of the limiting teeth 221 and the one-way sliding teeth 230, so that the mask can be worn.

When the mask needs to be loosened, one side of the adjusting arm 220, which is far away from the limiting tooth 221, is pressed, so that the limiting tooth 221 is lifted up by overcoming the elasticity of the reset torsion spring 240, the limiting tooth 221 is separated from the one-way sliding tooth 230, the reverse sliding of the adjusting mechanism 200 can be realized, and the loosening of the mask is realized.

As shown in fig. 1-7, in one embodiment, the attachment device 300 is a hook 310. When in use, the ear belt 400 is hung on the hook 310. The connecting device 300 having such a structure is simple.

Of course, in order to further improve the adaptability of the fixing device, the hook 310 on each side may be provided as a hook having two bent portions facing in opposite directions, so that the opposite hook 310 can be used to connect with the ear band 400 when necessary, i.e., when the mask ear band 400 is long.

As shown in fig. 1-7, in one embodiment, the number of hooks 310 is one or two,

when the number of the hooks 310 is one, the hooks 310 are disposed between the two sliders 210 and are fixedly connected to the two sliders 210.

When the number of the hooks 310 is two, the two hooks 310 are respectively disposed on the two sliders 210 and are fixedly connected to the sliders 210.

The connecting device 300 with the structure is simple in structure, and when the number of the hooks 310 is two, the width of the ear band 400 can be increased, the ear band is prevented from contacting with the connecting part of the ear and the head, and discomfort is reduced.

As shown in fig. 8 to 9, in an embodiment, the connecting device 300 is a limiting rod 320 having a limiting groove 321, the limiting rod 320 is fixedly connected to the two sliding blocks 210, and two ends of the limiting rod extend to a side of the two sliding blocks 210 facing away from each other.

When in use, the ear belt 400 is clamped in the limiting groove 321. The connecting device 300 with the structure is simple in structure, and the limiting rod 320 has a certain length, so that the ear belt 400 can be prevented from contacting with the connecting part of the ear and the head, and discomfort is reduced.

Similarly, in order to improve the adaptability of the fixing device, both sides of the limiting rod 320 are provided with limiting grooves 321.

As shown in fig. 8 to 9, in one embodiment, locking rings 322 are respectively disposed at both ends of the stopper rod 320, the locking rings 322 are rotatably coupled to the stopper rod 320, and one side of the locking rings 322 is provided with an opening. When the ear strap fixing device is used, the opening is aligned with the limiting groove 321, the ear strap 400 is clamped in the limiting groove 321, and then the locking ring 322 is rotated, so that the ear strap 400 can be prevented from being separated from the limiting groove 321. The stability of the device is improved.

The working principle of the utility model is as follows:

The utility model provides a fixing device has realized the continuous control of ear belt 400 position through setting up adjusting device to can carry out the continuous control to the elasticity degree of gauze mask ear belt 400, improve the adaptability of device.
