Detailed Description

The present utility model will be further described with reference to the accompanying drawings, and it should be noted that, while the present embodiment provides a detailed implementation and a specific operation process on the premise of the present technical solution, the protection scope of the present utility model is not limited to the present embodiment.

FIG. 1 is an exploded view of the present utility model; FIG. 2 is a schematic view of the front structure of the headband ring of the present utility model; FIG. 3 is a view of the utility model in a released state; fig. 4 is a drawing showing a state of the utility model after pulling, as shown in fig. 1-4, a self-adaptive wear ring structure, comprising a wear ring front part 1 and a wear ring rear part 2, wherein the left end and the right end of the wear ring front part 1 are respectively extended into and slidingly connected with the left end and the right end of the wear ring rear part 2, the end position of the wear ring front part 1, which is close to the wear ring rear part 2, is provided with a left end elastic rack and a right end elastic rack, the left end elastic rack and the right end elastic rack are respectively meshed with the upper side and the lower side of a linkage gear 5 which is rotatably arranged at the wear ring rear part 2, and the linkage gear 5 can play a role of linking the left end elastic rack and the right end elastic rack in the pulling and tightening processes, so that the pulled parts of the left rack and the right rack are equal in length all the time and are synchronous left and right. The left end elastic rack and the right end elastic rack in the embodiment have certain toughness, so that the bending requirement is met; the left end elastic rack and the right end elastic rack are connected with the rear part 2 of the head-wearing ring through self-adaptive elastic pieces.

The self-adaptive elastic piece in the embodiment is a constant force coil spring 4, the constant force coil spring 4 is arranged in a limit groove 7 in the rear part 2 of the head-wearing ring, and the side wall of one end of the constant force coil spring 4 extends out of the limit groove 7 and is connected with the left end elastic rack or the right end elastic rack through a rivet 3. The constant force coil spring 4 has the characteristic that the tightening force cannot be changed along with the change of the stretching length, so that when people with different head circumferences use the constant tightening force can be provided for the whole head ring, the user with large head circumference cannot feel too tight of the hoop, and the experience of the head ring is reduced.

Preferably, an anti-clamping allowance is reserved between one end of the left-end elastic rack, which is close to the front part 1 of the head-wearing ring, and the end of the right-end elastic rack, which is close to the front part 1 of the head-wearing ring, and the other end of the rear part 2 of the head-wearing ring. That is, the head-wearing ring is in a natural tightening state under the condition that no force is applied, and an anti-clamping allowance is reserved between the head-wearing ring front part 1 and the head-wearing ring rear part 2, so that racks on two sides of the head-wearing ring front part 1 cannot be fully retracted into the head-wearing ring rear part 2, and the head-wearing ring is prevented from tightening and clamping hair of a wearer when the head-wearing ring is taken off.

Preferably, the front end of the head-wearing ring is provided with a limiting bulge 6 at one end close to the left-end elastic rack and one end close to the right-end elastic rack.

Preferably, the rear part 2 of the head-wearing ring comprises a front cover 21 and a rear cover 22 which are mutually clamped, and the left-end elastic rack and the right-end elastic rack extend into a cavity surrounded by the front cover 21 and the rear cover 22.

The working flow is as follows: when the wear ring is worn, the curled part of the internal constant force coil spring 4 is pulled by hand, and straightened and lengthened, so that the left end elastic rack and the right end elastic rack of the front part 1 of the wear ring are synchronously pulled out under the action of the linkage gear 5, the size of the wear ring is increased, the constant force coil spring 4 can generate constant tightening force by itself after being stretched, when the hand loosens the rear part 2 of the wear ring, the rear part 2 of the wear ring is tightened and reset forwards under the tightening force of the constant force coil spring 4, the automatic tightening of the wear ring is realized, and the head of a user is hooped, so that the aim of self-adapting the head circumference size of the user is achieved.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting it, and although the present utility model has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that: the technical scheme of the utility model can be modified or replaced by the same, and the modified technical scheme cannot deviate from the spirit and scope of the technical scheme of the utility model.
