In order to make the technical field of the present invention better understand, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

The embodiment of the utility model provides a bandage adjusting device, as description attached figure 1 to figure 14, including two bandages 1, driving medium 2, locating part 3 and pressing part 4.

The transmission member 2 includes a first transmission portion 21 and a second transmission portion 22, the first transmission portion 21 and the second transmission portion 22 are disposed along an axial direction of the transmission member 2, and the first transmission portion 21 is connected to the two straps 1.

Taking the orientation shown in fig. 5 in the specification as an example, the two binding bands 1 are respectively arranged on the upper side and the lower side of the first transmission part 21, the first transmission part 21 can be specifically configured as a gear, the binding bands 1 should be configured as racks, that is, the two racks are engaged with the gear, the tightness adjustment can be realized when the two racks move in opposite directions, and in the process, the gear can synchronously rotate.

Of course, the first transmission portion 21 may be specifically configured as a synchronous wheel, the binding band 1 should be configured as a synchronous belt, the two synchronous belts can be adjusted in tightness while moving in opposite directions, and in this process, the synchronous wheel rotates synchronously. In addition to this, the connection between the first transmission part 21 and the strap 1 may be provided in other ways, and is not expanded here.

The limiting member 3 is used to connect with the second transmission portion 22, wherein the second transmission portion 22 can also be set as a gear, the limiting member 3 can be provided with an inner gear ring 33, the inner gear ring 33 and the gear can be engaged with each other, and the limiting member 3 can be set at a fixed position, so that when the second transmission portion 22 is connected with the limiting member 3 (the inner gear ring 33 is engaged with the gear), the relative position between the second transmission portion 22 and the limiting member 3 is fixed, that is, the relative position between the limiting member 3 and the transmission member 2 is fixed, and at this time, the two straps 1 cannot move.

The size of the second transmission part 22 can be larger than that of the first transmission part 21, a shaft shoulder 25 can be arranged between the second transmission part 22 and the first transmission part 21, and the size of the shaft shoulder 25 is between that of the second transmission part 22 and that of the first transmission part 21; the end face of the shoulder 25 facing the first transmission part 21 can be always attached to the two straps 1, which ensures a reliable connection between the first transmission part 21 and the two straps 1.

Of course, the second transmission portion 22 may also be specifically configured as a synchronous wheel, the limiting member 3 may be configured with a synchronous belt, the synchronous wheel and the synchronous belt are matched with each other, when the limiting member 3 is stationary, the second transmission portion 22 cannot move, that is, the relative position between the limiting member 3 and the transmission member 2 is fixed.

Besides, the connection mode between the second transmission portion 22 and the limiting member 3 can also adopt other setting modes according to actual needs, as long as it is ensured that when the second transmission portion 22 is connected with the limiting member 3, the relative position of the second transmission portion 22 and the limiting member 3 is fixed.

Pressing member 4 and locating part 3 link to each other, when pressing member 4 when pressing, then can drive locating part 3 and take place the position and remove, locating part 3 and second transmission portion 22 after the position removal break away from, and the unable motion of limiting part 3 restriction second transmission portion 22, two bandages 1 can move towards opposite direction this moment to realize the tight regulation, and when carrying out the tight regulation, driving medium 2 can be along with two relative motion of bandage 1 and synchronous motion.

It can be seen that, whether the two binding bands 1 can perform relative movement (whether tightness adjustment can be achieved) or not, finally, depending on whether the transmission member 2 is connected to the limiting member 3 or not, the first transmission portion 21 of the transmission member 2 can be connected to the two binding bands 1 all the time, and the second transmission portion 22 of the transmission member 2 can be selectively connected to the limiting member 3 under the action of the pressing member 4, that is, when the pressing member 4 is pressed, the second transmission portion 22 is separated from the limiting member 3, the two binding bands 1 can perform relative movement, and when the pressing member 4 is released, the second transmission portion 22 is connected to the limiting member 3, and the two binding bands 1 cannot perform relative movement.

Referring to the accompanying drawings 4, 10 and 11 in the specification, the bandage adjusting device further comprises a coil spring 5, the coil spring 5 is arranged on the end face, facing the pressing piece 4, of the transmission piece 2, the inner end of the coil spring 5 is fixed in position relative to the transmission piece 2, and the outer end of the coil spring 5 is fixed on the end face of the transmission piece 2.

The coil spring 5 comprises an inner end and an outer end, the middle part of the coil spring is continuously wound to form a plurality of closed loops, wherein the position of the inner end of the coil spring 5 is fixed compared with the position of the transmission piece 2, namely, the inner end of the coil spring 5 can be fixed at a fixed point; for example: aiming at the transmission piece 2, the transmission piece can rotate around the fixed shaft, the inner end of the coil spring 5 can be fixed on the fixed shaft, and in the rotating process of the transmission piece 2, the inner end of the coil spring 5 and the fixed shaft are both kept fixed; the outer end of the coil spring 5 is fixed on the end surface of the transmission member 2, so that when the two binding bands 1 move relatively (when the tightness is adjusted), the inner end of the coil spring 5 is always fixed, the outer end of the coil spring 5 and the transmission member 2 move synchronously, and the coil spring 5 is stretched.

The main functions of the coil spring 5 are: when the two binding bands 1 move relatively (when the tightness is adjusted), the coil spring 5 can provide damping feeling for a user in the process of being stretched, so that the user has good adjusting hand feeling; meanwhile, because the coil spring 5 acts on the driving medium 2 all the time, when the tightness adjustment is finished, the coil spring 5 can apply certain locking force to the two binding bands 1, so that the two binding bands 1 are tightly attached to the head of a user, and the binding band adjusting device is prevented from falling off from the head of the user.

In order to ensure that the outer end of the coil spring 5 and the actuator 2 are securely fixed, the outer end of the coil spring 5 may be provided with a first edge 51 and a second edge 52, the first edge 51 and the second edge 52 are connected with each other and arranged at an angle, and the second edge 52 is arranged at the end of the coil spring 5, as shown in fig. 11 in the specification.
