Description

Technical Field

[0001] This utility model relates to the field of helmet-related technology, and in particular to a helmet with a removable inner liner that is easy to clean. Background Technology

[0002] A liner is typically installed inside a helmet to improve wearing comfort. This liner comes into direct contact with hair and skin, and in hot weather, it easily absorbs a lot of sweat. Over time, this sweat absorption can lead to odors and bacterial growth, necessitating regular helmet cleaning. However, due to the large size of helmets, cleaning is often cumbersome and prone to incomplete cleaning. Most helmet liners are single-piece structures, and even those that are removable present inconvenience during the cleaning process.

[0003] Chinese Patent Publication No. CN221355911U, published on July 19, 2024, discloses a helmet with a quickly removable inner liner, comprising a helmet body and an inner liner. The helmet body is characterized by detachable buckles evenly distributed on it, and the inner liner is provided with clips and Velcro. The clips are evenly distributed around the perimeter of the inner liner relative to the detachable buckles on the helmet body. The inner liner and helmet body are detachably connected via the clips, detachable buckles, and Velcro. The detachable buckles include a fixing frame, a mounting bracket, a return spring, a disassembly button, a locking mechanism, and a mounting block. The fixing frame is a hollow structure with through holes, and the mounting bracket, return spring, disassembly button, locking mechanism, and mounting block are all housed within the fixing frame. A drawback of this invention is that the inner liner is a single, integral structure, making cleaning difficult after disassembly. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of existing helmets where the inner liner is a single structure and is not easy to clean after disassembly, and provides a helmet with a removable and easy-to-clean inner liner that can be disassembled in sections.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A removable, easy-to-clean helmet comprising: case; A disassembly block is provided, and several disassembly blocks are arranged in a circular pattern on the inner side of the housing. The disassembly blocks are detachably connected to the housing. A fixing component, which is mounted on the upper end of the housing and connected to the disassembly block; A limiting ring is installed at the lower end of the housing.

[0006] The shell is the main body of the helmet. The inner side of the helmet is equipped with a disassembly block. The inner liner is composed of several circumferentially distributed components. The disassembly block can be disassembled into several pieces for cleaning during disassembly. During installation, it is fixed by a fixing component installed at the top of the shell, which fixes the disassembly block to the inner side of the shell. Then, a limit ring is installed at the lower end of the shell to restrict the lower end of the disassembly block inside the shell and prevent it from falling off, thus achieving the purpose of disassembling the inner liner in sections.

[0007] Preferably, the shell is hemispherical in shape, and the disassembly block matches the inner wall of the shell. A positioning block is provided on the inner wall of the shell, and a positioning groove is provided on the disassembly block, with the positioning block and positioning groove matching. The hemispherical shell fits the head, and the shape of the disassembly block matches the inner wall of the shell. Several disassembly blocks fit together to form a hemispherical shape that fits the inner wall of the shell. When installing the disassembly block, the positioning groove on the outer side of the disassembly block engages with the positioning block on the inner wall of the shell. The disassembly block is positioned by the cooperation of the positioning block and the positioning groove, ensuring that several disassembly blocks form a complete spherical fit with the shell. The disassembly block is made of EPP material. This design allows for the disassembly and assembly of the inner liner in sections.

[0008] Preferably, the fixing component includes a screw and a pressing plate. The lower end of the screw passes through the housing and is positioned inside the housing. The pressing plate is installed at the lower end of the screw. The end of the disassembly block near the screw has a fitting groove that matches the screw. The inner side of the disassembly block has a pressing groove that corresponds to the pressing plate. After the disassembly block is installed, the screw passes through the top of the housing, fitting with the fitting groove of the disassembly block. After the upper end of the screw passes through the housing, the pressing plate at the lower end of the screw fits with the pressing plate on the disassembly block. The upper end of the disassembly block is fixed by the pressing of the pressing plate within the pressing groove. This design can fix one end of the disassembly block.

[0009] Preferably, the upper end of the screw is provided with a fixing cap, and the lower end of the fixing cap is provided with a threaded hole. The upper end of the screw is placed in the threaded hole and threadedly connected to the fixing cap. The fixing cap is provided with several circumferentially distributed friction blocks. The fixing cap is installed at the upper end of the screw that passes through the housing. The upper end of the screw is inserted into the threaded hole of the fixing cap. The screw is fixed by tightening the fixing cap. Tightening the screw drives the extrusion plate to extrude the disassembly block. The screw is disassembled by tightening the fixing cap. The circumferentially distributed friction blocks are installed on the fixing cap, which facilitates the rotation of the fixing cap. This design allows for quick disassembly and assembly of the screw.

[0010] Preferably, the limiting ring includes a bottom ring, an inner ring, and an outer ring. The limiting ring has a U-shaped cross-section. The inner ring is installed inside the bottom ring, and the outer ring is installed outside the base plate. A screwing block is installed at the lower end of the housing. The inner side of the outer ring is threadedly connected to the screwing block. A limiting groove is installed at the lower end of the disassembly block, and the upper end of the inner ring is placed in the limiting groove and corresponds to it. The limiting ring is installed at the lower end of the housing, restricting the disassembly block within the housing. Rotating the U-shaped limiting ring installs the limiting ring through the threaded connection between the outer ring and the screwing block. The bottom ring of the limiting ring fits against the bottom surface of the opening of the housing. At the same time, the inner ring is inserted into the limiting groove of the disassembly block. At this time, the top of the disassembly block is pressed and fixed by a pressing plate, and the lower end of the disassembly block is limited by the limiting ring. This design can restrict the position of the disassembly block.

[0011] Preferably, the bottom ring is provided with insertion holes and a rotating rod. The rotating rod has a U-shaped cross-section, and its two ends are respectively placed in the insertion holes on both sides of the bottom ring. Since the limiting ring is installed on the bottom surface of the housing, it needs to be rotated when the disassembly block needs to be removed. The U-shaped limiting ring is not easy to rotate, so a rotating rod is installed on the limiting ring. The rotating rod is separable from the limiting ring. When it is necessary to rotate the limiting ring, the two ends of the rotating rod are inserted into the insertion holes at both ends, and then the limiting ring is rotated by rotating the rotating rod. This design facilitates the rotation of the limiting ring.

[0012] Preferably, support columns are installed at both ends of the inner side of the disassembly block, and the disassembly block has several evenly distributed exchange holes. The support columns, installed on the inner wall of the disassembly block and in contact with the scalp, create a gap between the disassembly block and the scalp, reducing the pressure area of ​​the disassembly block. The support columns are made of flexible material, providing cushioning and preventing harm to the body from external impacts. Simultaneously, the evenly distributed exchange holes on the disassembly block allow for air exchange with the outside, increasing air circulation. The presence of the support columns also accelerates internal air circulation. This design promotes faster airflow.

[0013] Preferably, the upper end of the shell is provided with several circumferentially distributed vent holes. A spherical shell is difficult to handle; therefore, providing several circumferentially distributed vent holes at the upper end of the shell not only improves the air permeability inside the shell but also makes it easier to handle. This design increases air permeability.

[0014] The beneficial effects of this utility model are: it allows for the disassembly and assembly of the lining in sections, it allows for the fixing of one end of the disassembly block, it allows for quick disassembly and assembly of the screw, it allows for the restriction of the position of the disassembly block, it allows for easy rotation of the limiting ring, and it increases breathability.
