Abstract
The utility mode provides a helmet band locking device. The helmet band locking device is characterized by comprising a rear cover plate and an adjusting frame connected with the rear cover plate. Openings are placed on two sides of the adjusting frame; two helmet bands are respectively inserted in the openings from two sides; rack grooves are placed inside the two helmet bands; a round hole is formed on the surface of the adjusting frame; ratchets are placed on the periphery of the round hole; a shaft rod is placed in the center of the round hole; an adjusting gear and a clamping wheel are sleeved on the shaft rod; the adjusting gear is fixedly connected with the clamping wheel; the adjusting gear is meshed with racks of the rack grooves inside the helmet bands; clamping teeth capable of clamping in the ratchets are placed on the periphery of the clamping wheel, and are placed on an elastic cantilever formed on the periphery of the clamping wheel in a hollow mode; an adjusting turn-knob is covered outside the clamping wheel; and the inside lateral side of the adjusting turn-knob stretches into a hollow position of the periphery of the clamping wheel, and can drive the clamping wheel to rotate. Compared with the prior art, the helmet band locking device has the advantages of being very high in self-locking performance and not easy to loose. The sizes of the helmet bands are freely and breezily adjusted according to different head forms. The helmet band locking device is comfortable to wear, safe and reliable.
Description
Technical field
The utility model relates to a kind of helmet cap hoop locking device.
Background technology
In recent years, electric bicycle progressively replaces bicycle becomes people's walking-replacing tool preferably.But along with being on the increase of vehicle, the traffic accident that electric bicycle causes constantly increases, and according to incompletely statistics, in present all kinds of reason traffic accidents, the traffic accident relevant with electric bicycle accounts for more than 50%.In the electric bicycle process of riding, clash into the accident of falling down and to cause very large infringement to head.The reason of wearing bicycle helmet is very simple also very important, protection head, Harm reduction.Report according to the research of American Highway security insurance shows: U.S. 1999 dead number by bike has 98% not helmet, and the people who helmets in the shock accident makes the danger coefficient that they sustain a severe head injury reduce 85%, in surpassing the death by accident by bike of 500 examples every year, it is that head is subject to mortal injury and causes that 75% the cause of death is arranged.Medical research is found, the electric bicycle of the riding person that do not helmet, if when clashing into head on ground, tend to make brain to cause oedema hemorrhage, the person can make the head that is hit stop relatively slowly and wear the helmet, in the helmet, the sphere of polymerization but can absorb impact, can prevent 85% head injuries, and has greatly reduced degree of injury and accident death rate.
The effect of the helmet and important, but because helmet wearer is different, head dummy is different, and how making each user feel comfortable is the problem that needs solve.
Summary of the invention
Therefore, main purpose of the present utility model is to solve the deficiency that has the helmet now, designs a kind of helmet cap hoop locking device.
For realizing above purpose, the technical scheme that the utility model adopts is to provide a kind of helmet cap hoop locking device, it is characterized in that comprising: back shroud; Conditioning box, be connected with back shroud, described conditioning box both sides are provided with opening, article two, the cap hoop respectively from both sides to inserting described opening, described two cap hoop inboards are provided with rach slot, described conditioning box surface has circular hole, described circular hole periphery is provided with ratchet, described center of circular hole is established an axostylus axostyle, and described shaft rod upper sleeve is provided with adjusting gear and card wheel, and described adjusting gear is fixedly connected with the card wheel; The tooth bar engagement of the inboard rach slot of described adjusting gear and described cap hoop; The outer rim of described card wheel is provided with the latch that can snap in described ratchet, and described latch is arranged on the elastic cantilever of described card wheel edge hollow out formation; One regulates turn-knob covers outside described card wheel, and described adjusting turn-knob medial surface is provided with and stretches into card wheel edge hollow part and can drive described adjusting gear and the rotation of card wheel.
Optionally, described back shroud is to be made by elastomeric material.
Optionally, described adjusting turn-knob outer surface adopts elastomeric material TPE or TPR and the moulding of engineering plastics ABS material secondary injection moulding.
After having adopted technique scheme, the utility model compared with prior art has very high self-locking property and is difficult for loosening characteristics, and is free and relaxed according to different head dummy adjusting helmet (safety cap) cap hoop sizes, comfortable safe and reliable.In addition, in proximity head nape both sides, be provided with an elastomer structure, when turn-knob is locked, can regulate voluntarily according to different head dummys, to guarantee the comfortableness of different helmet wearer; Simultaneously, turn-knob part outer surface adopts elastomeric material TPE or TPR and the moulding of engineering plastics ABS material secondary injection moulding, makes the dual color of adjusting turn-knob appearance attractive in appearance beautiful, and has more soft, comfortable feel.
