Abstract
The utility model discloses a helmet adjusting hoop, comprising a hoop bracket, in which a guide groove is formed, where two strip-hoops are arranged, and inside the strip-hoop is provided with a rack groove, the surface of hoop bracket is provided with a hole, outer of which is sleeved by an adjusting dial and around which is provided with ratchets, between the hole and the adjusting dial is sleeved by a wheel, the outer margin of which is provided with latches that can insert into the ratchets, the latches arranged on the elastic cantilever formed by hollowing the wheel margin, the inner side of wheel has a gear engageable with the rack in the rack groove, the inner side of adjusting dial is provided with a handspike that can stretch into the hollowing and drive the wheel. The utility model adds the design of anti-reverse-rotation retaining mechanism on the base of current helmet adjusting hoop, therefore, the helmet can be worn reliably and hard when it is adjusted to the right position. The utility model has reasonable structure and convenient use.
Description
Technical field
The utility model relates to a kind of adjusting hoop, particularly a kind of helmet adjusting hoop that can make the helmet firmly cosily be worn on user's head on the helmet that is installed in.
Background technology
At present, common helmet adjusting hoop comprises cap hoop support 1 as shown in Figure 1, form a gathering sill 2 in the described cap hoop support 1, two strip cap hoops 3 are installed in gathering sill 2, strip cap hoop 3 inboards are provided with rach slot 31, cap hoop support 1 surface has circular hole 4, and circular hole 4 overcoats are debug joint rotating disk 6; Rotation adjusting rotating disk 6 during use by the tooth bar in the 7 drive rach slots 31 of the gear on the adjusting rotating disk 6, thereby makes the firm comfortable purpose of head-mount that strip cap hoop 3 is done relatively or rightabout moves and reaches the helmet and user in gathering sill 2; But existing helmet adjusting hoop is owing to lack reverse locking mechanism, when the user is being given a shock or other are when influencing, adjusting hoop becomes flexible gradually with regard to easy generation relative motion, at this moment often needing to regulate once more rotating disk tightens it helmet is firmly worn, use comfortable inadequately reliably, be necessary to do further improvement.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides helmet adjusting hoop a kind of rational in infrastructure, easy to use and reliable.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of helmet adjusting hoop, comprise cap hoop support, form a gathering sill in the described cap hoop support, two strip cap hoops are installed in gathering sill, strip cap hoop inboard is provided with rach slot, cap hoop rack surface has circular hole, the circular hole overcoat is debug the joint rotating disk, described circular hole periphery is provided with ratchet, also be set with the card wheel between circular hole and the adjusting rotating disk, the outer rim of described card wheel is provided with the latch that can snap in the above-mentioned ratchet, and described latch is arranged on the elastic cantilever of card wheel edge hollow out formation, card wheel medial surface has the gear that matches with tooth bar in the rach slot, regulates the rotating disk medial surface and is provided with and stretches into the push rod that above-mentioned hollow out can drive the rotation of card wheel.
The beneficial effects of the utility model are: after the user puts on the helmet, rotation is regulated rotating disk helmet adjusting hoop is adjusted to correct position, owing on the cap hoop support of helmet adjusting hoop, be provided with the circular hole of band ratchet, regulate and be set with the card wheel on the rotating disk, card wheel outer rim is provided with the latch that can snap in the above-mentioned ratchet, like this after the adjusting of helmet adjusting hoop puts in place, thereby latch promptly snaps in and has formed reverse retaining mechanism in the ratchet, the user is being given a shock or other are when influencing, the phenomenon that adjusting hoop is loosening gradually with regard to not occurring relative motion again, the helmet can be worn on user's head all the time solid and reliablely.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structure broken away view of existing product;
Fig. 2 is a structure broken away view of the present utility model;
Fig. 3 is a structural representation of regulating rotating disk;
Fig. 4 is the structural representation of card wheel.
The specific embodiment
With reference to Fig. 2, Fig. 3, Fig. 4, a kind of helmet adjusting hoop, comprise cap hoop support 1, form a gathering sill 2 in the described cap hoop support 1, two strip cap hoops 3 are installed in gathering sill 2, strip cap hoop 3 inboards are provided with rach slot 31, cap hoop support 1 surface has circular hole 4, circular hole 4 overcoats are debug joint rotating disk 6, described circular hole 4 peripheries are provided with ratchet 41, also be set with card wheel 5 between circular hole 4 and the adjusting rotating disk 6, the outer rim of described card wheel 5 is provided with the latch 51 that can snap in the above-mentioned ratchet 41, described latch is arranged on the elastic cantilever 52 that card wheel 5 edge hollow outs 53 form, and card wheel 5 medial surfaces have the gear 54 that matches with tooth bar in the rach slot 31, regulates rotating disk 6 medial surfaces and is provided with and stretches into the push rod 62 that above-mentioned hollow out 53 can drive the rotation of card wheel.
After the user puts on the helmet, regulate rotating disk 6 by rotation, under the drive of regulating rotating disk 6, be installed in the card wheel of regulating between rotating disk 6 and the circular hole 45 rotates thereupon, thereby be arranged on gear 54 on the card wheel 5 stir tooth bar in the rach slot 31 make two strip cap hoops 3 to relative to or opposite direction move helmet adjusting hoop adjusted to correct position, owing on the cap hoop support of helmet adjusting hoop, be provided with the circular hole 4 of band ratchet 41, card wheel 5 outer rims are provided with the latch 51 that can snap in the above-mentioned ratchet 41, like this after the adjusting of helmet adjusting hoop puts in place, thereby latch 51 promptly snaps in and has formed reverse retaining mechanism in the ratchet 41, the user is being given a shock or other are when influencing, the phenomenon that adjusting hoop is loosening gradually with regard to not occurring relative motion again, the helmet can be worn on user's head all the time solid and reliablely.
In addition, in above-mentioned adjustment process, be provided with push rod 62 owing to regulate rotating disk 6, this push rod 62 heads in the hollow out 53 in the card wheel 5, when rotating disk 6 was regulated in rotation, push rod 62 pushed elastic cantilever 52 and makes its radial contraction along card wheel 5 in rotation process, and the latch 51 that is arranged on the elastic cantilever 52 breaks away from ratchet 41, at this moment reverse retaining mechanism is removed, and 31 rotations are adjusted helmet adjusting hoop thereby gear 54 is stirred rach slot; This product has only to be regulated rotating disk 6 by rotation and could remove the reverse retaining mechanisms that latch 51 snaps in formation in the ratchet 41, thereby the reliability when having guaranteed the use of helmet adjusting hoop makes the helmet be worn on user's head all the time after adjusting puts in place solid and reliablely.
The utility model is rational in infrastructure, easy to use and reliable, makes the helmet can be worn on user's head all the time after the adjusting of helmet adjusting hoop is put in place solid and reliablely.
