[0012] 1. Reduce stress and improve comfort:

[0013] This invention designs an auxiliary head frame that works in conjunction with a fitting frame, which can effectively transfer part of the weight of the fitting frame to the head, thereby reducing the pressure of the lenses and fitting frame directly on the patient's nose and ears during fitting, significantly reducing the patient's discomfort during the fitting process, and improving the comfort of the fitting.

[0014] 2. Flexible adjustment function:

[0015] This utility model features adjustment holes and adjustment gears on the frame, which, together with the strip holes and adjustment teeth on the headband, allow users to easily adjust the tightness of the headband according to their own head circumference, ensuring that the auxiliary head frame is worn securely and comfortably on the head. In addition, through the cooperation of the small gears and racks in the openings, users can flexibly adjust the height of the hooks to adapt to different sizes of trial frames or the needs of different patients, increasing the flexibility and applicability of use.

[0016] 3. Easy to operate and maintain:

[0017] The structure of this utility model is simple and clear, and the adjustment mechanism is easy to operate. Users can adjust the tightness of the headband and the height of the hook without complicated steps. At the same time, the cooperation between the components is tight and stable, making it easy to clean and maintain daily, thus extending the service life of the product.

[0018] 4. Improve fitting efficiency:

[0019] The use of this auxiliary headband makes the fitting process smoother, reduces interruptions caused by discomfort or improper adjustment, thereby improving the efficiency of fitting work and providing ophthalmologists and optometrists with a more convenient tool. Attached Figure Description

[0020] Figure 1 This is a schematic diagram of the structure of this utility model;

[0021] Figure 2 This is an exploded view of the structure of this utility model. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1-2 An auxiliary headband for use with a trial fitting frame is designed to effectively solve the problem of pressure on the user's nose and ears caused by traditional trial fitting frames through structural innovation, ensuring comfort even during long-term use. Specifically:

[0024] The headband includes a frame 1 and a headband 2 that work together to form a ring structure for easy wearing on the human head. It is not only ergonomic, but also ensures a close fit to the head contour when worn, reducing gaps and improving wearing stability. At the same time, the frame 1 and the headband 2 are both designed in a semi-circular arc shape, which increases the aesthetics and makes the whole headband look more fashionable and modern.

[0025] To enable adjustment of the headband 2, insertion slots for engaging with the ends of the headband 2 are provided on both sides of the frame 1. Adjustment holes are also provided on the frame 1 at the insertion slots, with an adjustment gear 7 embedded within each hole. Slotted holes are provided on both sides of the headband 2, with adjusting teeth on the inner wall of each slot for engaging with the adjusting gear 7 to adjust the tightness of the headband 2. The ends of the headband 2 can be easily inserted and secured through the insertion slots, achieving a connection with the frame 1. Simultaneously, users can rotate the adjusting gear 7 to engage with the adjusting teeth, changing the position of the headband 2 within the adjustment holes, thus easily adjusting the tightness of the headband 2 to meet the needs of users with different head circumferences.

[0026] Preferably, the inner side of the adjustment hole is sealed by the hole plug 8, and the outer side of the adjustment hole is equipped with a handwheel 3 that connects and cooperates with the adjustment gear 7. This not only makes it easy to operate, but also allows for precise adjustment, ensuring that the headband 2 is always kept in the most comfortable tightness.

[0027] In order to cooperate with the trial frame, an opening is provided in the middle of the frame 1. A vertically arranged rack 4 is inserted into the opening. A hook 5 for supporting the trial frame is hinged to the bottom of the rack 4. A small gear 10 is installed on the frame 1 at the opening to cooperate with the rack 4 to adjust the height of the hook 5. This design allows users to adjust the height of the hook 5 by rotating the small gear 10 at the opening according to the size of the trial frame and their own needs, so as to ensure that the trial frame is stably and comfortably suspended on the head.

[0028] Preferably, a knob 6 is also installed on the frame 1 at the opening. The knob 6 is connected to the pinion 10 through the bushing 9, so that the pinion 10 can be rotated by the knob 6.

[0029] The hook 5 is hinged to the rack 4 via a horizontally arranged round shaft 11, so that when the rack 4 moves up and down, the hook 5 can always remain vertical, so as to better support and cooperate with the fitting frame.

[0030] The rack 4 is vertically inclined at an angle of 70°-80°, which is not only aesthetically pleasing but also reduces direct pressure on the head while maintaining the stability of the hook 5, thus further improving wearing comfort.

[0031] Both the frame 1 and the headband 2 are made of high-polymer materials, which have excellent properties such as light weight, high strength, and corrosion resistance. This not only ensures the durability and stability of the headband, but also reduces the overall weight, making it easier and more comfortable to wear.

[0032] When in use, users only need to fix the headband to their head and easily adjust the tightness of the headband 2 by rotating the handwheels 3 on both sides to ensure that the headband fits the head securely and comfortably.

[0033] Then, put the trial frame on your face and hook the middle beam of the trial frame with the hook 5 of the headband. By rotating the knob 6, the user can adjust the height of the hook 5 as needed, so as to easily lift the trial frame and reduce the pressure of the nose pads and temples on the bridge of the nose and ears.

[0034] This design not only improves the wearing comfort of the fitting frame, but also allows users to remain relaxed and happy during long-term fitting, effectively avoiding the discomfort caused by traditional fitting frames.

[0035] The present invention provides an auxiliary head frame for use with a fitting frame. Through its unique design and flexible adjustment function, it effectively solves the problems existing in the prior art, improves the patient's fitting experience, and also brings convenience to the fitting work.
