During installation, the webbing is installed in the webbing slot from the installation slot inward, and then the head lock height adjustment rack is longitudinally installed in the rack slot, so that the webbing and the head lock height adjustment rack will not interfere with each other, ensuring the working stability of the overall head lock structure and the webbing system.

[0006] Preferably, the rack slot is longitudinally opened, the webbing slot is transversely opened, and the webbing and the head lock height adjustment rack are perpendicular to each other. The webbing transversely installed in the rack slot will be flatter and easier to adapt to the head structure.

[0007] Preferably, the rack slot is provided at the front side of the webbing slot, and the head lock height rack is located at the front side of the webbing. During installation, the webbing is installed inwardly from the installation slot into the webbing slot, and then the head lock height adjustment rack is longitudinally installed in the rack slot, so that the head lock height adjustment rack can also limit the webbing and prevent it from falling off.

[0008] Preferably, an installation groove perpendicular to the webbing through groove is formed in the adjusting base, and the installation groove communicates with the webbing through groove. The installation groove is perpendicular and communicates with the webbing through groove, which is convenient for quickly installing the webbing.

[0009] Preferably, longitudinal positioning grooves are formed at the upper and lower ends of the positioning block. The head lock height adjustment rack is embedded in the longitudinal positioning groove for quick installation and positioning and to ensure the stability of the work.

[0010] Preferably, a transverse positioning groove is formed in the middle of the positioning block, and the adjusting base is embedded in the transverse positioning groove. The webbing is installed through the adjusting base, and the webbing extends along the transverse positioning groove to both sides.

[0011] Preferably, the transverse positioning groove is an arc groove. During installation, the webbing can extend along the arc of the transverse positioning groove to both sides. The arc-shaped transverse positioning groove can guide the extension of the webbing, naturally forming an arc, which is convenient for fitting the head and ensuring the flatness of the webbing.

[0012] Therefore, the head lock adjusting base for a helmet of the present invention has the following advantages: it is convenient for installation and manufacturing, the adjusting rack and the webbing system will not interfere by changing the position and direction of the webbing, the webbing direction is more reasonable, and the overall structure works stably.

[0020] The technical solution of the utility model will be further specifically described below through embodiments in conjunction with the accompanying drawings.

[0021] Embodiment:

[0022] As Figure 1 and 2 shown in Figures 3, 4, 5, and 6, a headlock adjustment base for a helmet includes a housing 1 installed inside the helmet. A headlock height adjustment rack 2 extending downward is integrally formed on the housing 1. A positioning block 3 is installed below the housing 1. Longitudinal positioning grooves 4 are provided at the upper and lower ends of the positioning block 3, and the headlock height adjustment rack 2 is embedded in the longitudinal positioning grooves 4.

[0023] A transverse positioning groove 5 is provided in the middle of the positioning block 3. The transverse positioning groove 5 is an arc-shaped groove, and an adjustment base 6 is embedded and installed in the transverse positioning groove 5.

[0024] The adjustment base 6 is successively provided with a rack through groove 7 and a webbing through groove 8 from front to back. The rack through groove 7 is longitudinally penetrated, and the webbing through groove 8 is transversely penetrated. The headlock height adjustment rack 2 is installed in the rack through groove 7. The webbing 9 is perpendicular to the headlock height adjustment rack 2, and the headlock height adjustment rack 2 is located on the front side of the webbing 9.

[0025] The webbing 9 is transversely installed through the webbing through groove 8. Both ends of the webbing 9 extend along the transverse positioning groove 5 to both sides. An installation groove 10 is provided on the front side of the adjustment base 6. The installation groove 10 is perpendicular to the webbing through groove 8 and is communicated with the webbing through groove 8.

[0026] During installation, the webbing 9 is installed into the webbing through groove 8 from the installation groove 10. The webbing 9 extends along the arc of the transverse positioning groove 5 to both sides. Then, the headlock height adjustment rack 2 is longitudinally installed in the rack through groove 7. In this way, the webbing 9 and the headlock height adjustment rack 2 will not interfere with each other, ensuring the stable operation of the overall headlock structure and the webbing 9 system.
