[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 , the utility model provides a technical solution:

[0025] See also Figure 1-5 As shown, the adjustable headband includes a headband body 1, a mounting block 3 is fixedly mounted on the headband body 1, a first sphere 6 is arranged on one side of the mounting block 3, a first telescopic rod 4 and a reset spring 5 are fixedly mounted between the mounting block 3 and the first sphere 6, the reset spring 5 is arranged on the outside of the first telescopic rod 4, a plastic strip 2 is slidably arranged inside the headband body 1, and a first arc groove 14 adapted to the first sphere 6 is opened on the plastic strip 2.

[0026] See also Figure 1-2 A fixing block 7 is fixedly installed at one end of the plastic strip 2 away from the headband body 1 , and the fixing block 7 is rotatably connected to a clamping plate 8 , and a torsion spring 9 is arranged between the fixing block 7 and the clamping plate 8 .

[0027] Since the splint 8 can rotate on the fixing block 7 through the torsion spring 9, this design allows the end of the plastic strip 2 to flexibly adapt to heads of different shapes and sizes. Regardless of whether the head is large or small, or the head shape is different, the splint 8 can be adaptively adjusted through the elastic action of the torsion spring 9 to ensure wearing comfort and stability.

[0028] The design of the torsion spring 9 not only provides the flexibility of rotation, but also ensures the stability of clamping. The elastic force of the torsion spring 9 can ensure that the clamping plate 8 can remain fixed after being adjusted to a suitable position, and is not easy to loosen or shift due to external factors.

[0029] See also Figure 1-2 , the two clamping plates 8 are symmetrically arranged.

[0030] The symmetrical design of the splint 8 can bring a visual and physical sense of balance, making the headband body 1 more stable when worn and not prone to shaking or tilting. This balance stability is very important for ensuring the user's wearing comfort and durability for long-term use.

[0031] See also Figure 1-2 The splint 8 is integrally formed with an anti-skid silicone strip 10 , and the number of the anti-skid silicone strips 10 is set to 16 groups, with 2 strips in each group.

[0032] The main function of the anti-skid silicone strips 10 is to increase the friction between the splint 8 and the head skin to prevent the headband body 1 from sliding or falling off during wearing. The setting of 16 groups of anti-skid silicone strips 10 greatly increases the anti-skid area, improves the anti-skid effect, and makes the headband body 1 more stable to wear.

[0033] The silicone material itself is soft and elastic, and will not cause discomfort when in contact with the skin. The one-piece design allows the anti-slip silicone strip 10 to be perfectly integrated with the splint 8 without protrusions or depressions, further improving the wearing comfort.

[0034] See also Figure 1-2 The material of the splint 8 is set to polyethylene.

[0035] Polyethylene is an odorless, non-toxic material, which makes it very suitable for products that come into direct contact with the human body. Users can use it with confidence without worrying about the release of harmful substances or irritation to the skin.

[0036] At the same time, polyethylene has excellent physical properties, including good mechanical strength, wear resistance and impact resistance. This enables the clamping plate 8 to maintain the stability of its shape and structure during long-term use and is not easy to deform or damage.

[0037] See also Figure 2 and Figure 5 A rotating rod 12 is rotatably connected to the headband body 1, an arc block 11 is fixedly installed at one end of the rotating rod 12, an electrode sheet 13 is arranged on the arc block 11, a second telescopic rod 15 and a telescopic spring 16 are fixedly installed on one side of the electrode sheet 13, a second sphere 17 is fixedly installed on one end of the second telescopic rod 15 and the telescopic spring 16 away from the electrode sheet 13, and a second arc groove 18 adapted to the second sphere 17 is opened on the headband body 1.

[0038] When the head ring body 1 is not in use, the arc block 11 and the head ring body 1 are cross-set, and then the rotating rod 12 is rotated to make the second sphere 17 correspond to the second arc groove 18. Then, due to the special shape of the arc-shaped depression of the second arc groove 18, the second sphere 17 is stuck on the second arc groove 18. At the same time, the elastic force of the telescopic spring 16 will press the second sphere 17 against the second arc groove 18. When the telescopic spring 16 pushes the second sphere 17 toward the direction of the second arc groove 18, the second sphere 17 will drive the telescopic end of the second telescopic rod 15 to stretch synchronously, and the second telescopic rod 15 can protect the telescopic spring 16.

[0039] The two electrode sheets 13 on the headband body 1 are internally provided with rotating copper strips, which can be automatically connected in series by rotation. The electrode sheets 13 are internally connected as a whole and can be adjusted during use to facilitate contact with different head shapes. One of the three copper electrode sheets 13 can be used when it contacts the second arc groove 18.

[0040] See also Figure 1 A knob is fixedly mounted on one end of the rotating rod 12 away from the arc-shaped block 11, and the outer wall of the knob is integrally formed with anti-skid particles.

[0041] The design of the knob allows the user to more conveniently rotate the rotating rod 12, thereby adjusting the arc block 11 and other components. This is suitable for scenes that require frequent adjustment or operation, such as mechanical devices, electronic equipment, etc.

[0042] The design of anti-skid particles can significantly increase the roughness of the knob surface, thereby increasing the friction between the user's hand and the knob. This makes it easier and more stable for the user to operate the knob, making it less likely to slip or fall out of the hand, which helps improve the accuracy and efficiency of the operation.

[0043] The presence of anti-slip particles also increases the tactile feel of the knob surface, allowing the user to feel a more obvious bumpy feel when holding the knob, which helps to enhance the stability and comfort of holding.

[0044] See also Figure 1-2 The arc block 11 is made of silicone material, the head ring body 1 is made of ABS plastic, and the electrode sheet 13 is made of copper sheet material.

[0045] The rubber material is usually soft and elastic, and the arc block 11 can provide better comfort when in contact with the skin, reduce pressure and friction on the skin, and avoid discomfort or pain. At the same time, the rubber material can adapt to the irregular shape of the skin surface, providing better fit and stability. This is especially important for the arc block 11 that needs to be in contact with the skin for a long time, which can reduce displacement or falling off caused by movement or activity.

[0046] ABS plastic has high strength and rigidity, and can withstand certain pressure and impact, ensuring the stability of the headband structure. At the same time, ABS plastic is relatively light and will not bring too much burden to the user, making it suitable for long-term wear.

[0047] The copper sheet material has good chemical stability and corrosion resistance, and can resist corrosive substances in the external environment, thereby reducing the possibility of damage or performance degradation of the electrode sheet 13 during use.

[0048] Working principle: If the user's head circumference is large, the user pulls the splint 8 to the side away from the headband body 1, and the plastic strip 2 will be stretched from the inside of the headband body 1. The first telescopic rod 4 and the return spring 5 on the mounting block 3 can be adjusted for telescopic adjustment. When the plastic strip 2 is pulled, the first sphere 6 can slide out of the first arc groove 14, and then slide into the other first arc grooves 14 for positioning, so as to prevent the plastic strip 2 from being pushed back into the headband body 1 with a slight push during use. By adjusting the length of the headband body 1, it can be ensured that the headband body 1 is better adapted to the head shape and size of different individuals, providing a more fitting and comfortable wearing experience.

[0049] The adjustable length of the headband body 1 makes it more convenient to wear and can be applied to a wider range of people. Whether it is children, adults or the elderly, as long as the headband body 1 has a sufficient adjustment range, it can be adjusted appropriately according to the actual situation to meet the needs of different users.

[0050] When the head ring body 1 is not in use, the arc block 11 and the head ring body 1 are cross-set, and then the rotating rod 12 is rotated to make the second sphere 17 correspond to the second arc groove 18. Then, due to the special shape of the arc-shaped depression of the second arc groove 18, the second sphere 17 is stuck on the second arc groove 18. At the same time, the elastic force of the telescopic spring 16 will press the second sphere 17 against the second arc groove 18. When the telescopic spring 16 pushes the second sphere 17 toward the direction of the second arc groove 18, the second sphere 17 will drive the telescopic end of the second telescopic rod 15 to stretch synchronously, and the second telescopic rod 15 can protect the telescopic spring 16.

[0051] The two electrode sheets 13 on the headband body 1 are internally provided with rotating copper strips, which can be automatically connected in series by rotation. The electrode sheets 13 are internally connected as a whole and can be adjusted during use to facilitate contact with different head shapes. One of the three copper electrode sheets 13 can be used when it contacts the second arc groove 18.
