Description

Technical Field

[0001] This utility model belongs to the field of headwear devices, and more specifically, relates to an adjustment structure for a headwear device. Background Technology

[0002] For example, CN120225086A discloses a body-wearing device for adapting to compressive forces on the wearer's head. The device may include a rigid support spanning the head in a substantially brim-oriented manner. The support may include a pair of extending arms that extend laterally and rearward away from the temples. A rear tensioning member places the free ends of the arms under lateral inward compressive forces resisted by the rigidity of the support, thereby avoiding compression of the temple area of ​​the head and increasing comfort. However, the first end of the cable on this device can be fixed to a main shaft rotatably mounted on a guide bracket, and the distance between the headpiece and the shell can only be adjusted via a single-stage pull cord. The adjustment precision is low, and the adjustment range is large, making it difficult to adjust to a comfortable position. Utility Model Content

[0025] Reference Figures 1 to 4As shown, an adjustment structure for a head-wearing device is provided, including a head-wearing device 1 and a support frame 2. A first pull cord 3 is provided at one end of the support frame 2. A first knob 11 is provided on one side of the head-wearing device 1. One end of the first pull cord 3 is connected to the first knob 11, and the other end of the first pull cord 3 is fixedly connected to the other side of the head-wearing device 1. A second knob 21 is provided at the end of the support frame 2 away from the first pull cord 3. A movable guide rail 4 is provided inside the support frame 2. The middle part of the first pull cord 3 is connected to the guide rail 4, and the guide rail 4 is connected to the second knob 21 via a second pull cord 5. The first pull cord 3 can move left and right within a U-shaped hole 41.

[0026] In some embodiments of this utility model, the head-wearing device 1 includes a headband 12 that surrounds the head and a top ring 13 that wraps around the top of the head. The rear end of the headband 12 is provided with a headband knob 15 for adjusting the circumference of the headband 12, and the top ring 13 is provided with a top ring knob 16 for adjusting the circumference of the top ring 13.

[0027] In some embodiments of this utility model, the front end of the headband 12 is fixedly connected to an arc-shaped retaining block 14 that is rigid and fits only the forehead.

[0028] In some embodiments of this utility model, the support frame 2 is configured as a hollow, irregularly shaped flat tube. The top of the support frame 2 is provided with a crescent structure 22, and through holes 221 are provided on both sides of the crescent structure 22. A guide tube 6 is provided in the through hole 221. The guide tube 6 is sleeved on the end of the first pull rope 3 near the support frame 2. A knob hole 23 is provided on the end of the support frame 2 away from the first pull rope 3. A second knob 21 is provided in the knob hole 23. The guide rail plate 4 is provided in the tube section between the crescent structure 22 and the knob hole 23.

[0029] In some embodiments of this invention, the conduit 6 is made of a material with a low coefficient of friction.

[0030] In some embodiments of this utility model, the guide rail plate 4 is provided with a U-shaped hole 41, which is connected to the middle part of the first pull rope 3.

[0031] In some embodiments of this utility model, the bottom of the guide rail plate 4 is provided with a mounting hole 42, one end of the second pull rope 5 is fixedly connected to the mounting hole 42, and the other end of the second pull rope 5 is connected to the second knob 21.

[0032] In some embodiments of this utility model, the head-wearing device 1 is made of a flexible material, such as polyethylene, polypropylene, or TPU, to ensure that it can deform flexibly to fit the human head when worn, thus providing a more comfortable wearing experience.

[0033] In this embodiment, the front end of the headband 12 is fixedly connected to the arc-shaped retaining block 14. The width of the arc-shaped retaining block 14 only covers the forehead and does not compress the temples. The arc-shaped retaining block 14 is made of a material with a certain degree of rigidity, and its span exceeds the width between the temples of most wearers, ensuring that the sides of the head-wearing device 1 will not compress the user's temples when worn. The rear end of the headband 12 is also provided with a headband knob 15, which can be used to adjust the circumference of the headband 12. The top ring 13 is provided with a top ring knob 16, which can be used to adjust the circumference of the top ring 13.

[0034] The left side of the headband 12 is fixedly connected to one end of the first pull rope 3, and the right side is provided with a first knob 11. The other end of the first pull rope 3 is fixedly connected to the first knob 11. When the first knob 11 is rotated, the first pull rope 3 can be wound up.

[0035] The support frame 2 has a hollow, irregularly shaped flat tube structure. A crescent-shaped structure 22 is located at the top, with through holes 221 on both sides. Low-friction material guide tubes 6 are respectively installed within the through holes 221. The support frame 2 has a knob hole 23, and a second knob 21 is installed within the knob hole 23. A guide rail 4 is installed within the tube section between the crescent-shaped structure 22 and the knob hole 23. The guide rail 4 has a U-shaped hole 41, and its bottom is connected to the second knob 21 via a second pull rope 5. The two-stage pull rope adjustment structure has a first-stage pull rope 3, one end of which is fixed to the left end of the head-wearing device 1. It passes through the left guide tube 6, enters the support frame 2, passes through the U-shaped hole on the guide rail 4, and then exits from the right guide tube 6 to connect with the first knob 11, forming the first-stage pull rope tensioning system. Its working principle is: rotating the first knob 11 allows the first pull rope 3 to be extended or retracted, thereby adjusting the distance between the head-wearing device 1 and the support frame 2. The second stage consists of a second pull rope 5 with guide rail 4 and a second knob 21 fixed at both ends. The principle is that by rotating the second knob 21, the second pull rope 5 can be extended or retracted, and the guide rail 4 can be controlled to slide up and down within the support frame 2, thereby indirectly controlling the change in the distance between the head-wearing device 1 and the support frame 2.

[0036] This invention allows for coarse adjustment of the distance between the head-wearing device and the support frame by first rotating the first knob, and then fine adjustment of the distance by rotating the second knob. Rotating the second knob causes the guide rail to move up and down via the second pull cord, which in turn causes the first pull cord to move slightly, thus achieving a fine-tuning effect with higher adjustment precision. After adjusting the first knob, the second knob can be used to adjust the device to a comfortable position for the user, making it easier to achieve the desired effect.

[0037] The above is a further detailed description of this utility model and should not be considered as a limitation on the specific implementation of this utility model. For those skilled in the art, simple deductions or substitutions without departing from the concept of this utility model are all within the protection scope of this utility model.
