Abstract
The utility model discloses a kind of belt governor motion of head-wearing display device, comprise head-wearing display device, belt etc., it is characterized in that: the belt of head-wearing display device has tooth bar, the tooth bar of one strap is above gear, the tooth bar of another strap, in the below of gear, twists gear by knob, and two belt relative directions move, after loosing one's grip, the pulling force between two belts is kept by ratchet device.This device is used for wearing display device, can obtain comfortable, effect easily.
Description
Technical field
The utility model relates to a kind of head-wearing device, especially a kind of belt regulating device of head-wearing display device.
Background technology
Mobile phone movie mirror or other head-wearing display device need to tie up on head with belt, and belt generally all adopts elastic cord, but elastic cord stretches tight on head always, of long duration uncomfortable, and tight belt can hinder blood circulation, unhealthful.If with not being with flexible belt, tightness is also difficult to control, and hand adjustment not, and also needs to take off adjustment, in order to be transferred to suitable length, sometimes needs repeatedly many times.Reasonable have the mode of similar jack to regulate, and this mode also needs push-and-pull on the other hand, grips on the other hand and control knob, operate very inconvenient.
Summary of the invention
In order to overcome above defect, the utility model provides one and wears belt governor motion, this mechanism utilizes rack-and-pinion, hand is stirred knob and just can impression be relied on to be transferred to optimal tightness accurately being worn on the head like a cork, meets the different tightness needs of different purposes (see a film, interactive game, 4D).Further, belt is connected with head-wearing display device buckle, is convenient to dismounting, can lay down belt easily during hand-held viewing, avoids the muscle muscle of belt to stumble.
The utility model solves the technical scheme that its technical matters adopts: head-wearing display device increases tooth bar on joined belt, the tooth bar of one end belt is arranged on the top of gear, the tooth bar of other end belt is arranged on the below of gear, gear is twisted by knob, two belt relative directions move, after loosing one's grip, the pulling force between two belts is kept by ratchet device.
The beneficial effects of the utility model are: along with wearing popularizing gradually of display device, wear the comfortableness of this kind equipment, convenience and just seem more and more important.
Accompanying drawing explanation
Fig. 1 rack-and-pinion governor motion;
Fig. 2, Fig. 3 snap catches;
Fig. 4 mobile phone movie mirror;
Fig. 5 ratchet device;
Fig. 6 belt;
Fig. 7 belt governor motion assembly.
In figure: 1. gear, 2. reed, 3. tooth bar, 4. belt, 5. gear wheel, 6. buckle, 7. cutting ferrule, 8. determine ratchet, 9. gear is conjuncted, 10. ratchet, and 11. knobs are conjuncted.
Embodiment
1. belt governor motion belt governor motion is made up of (Fig. 1) rack-and-pinion, two straps are placed in governor motion two ends respectively, one end belt (4, tooth bar (3) Fig. 6) is arranged on the upper end of gear (1), tooth bar on other end belt is arranged on the lower end of gear, twists gear by knob, and two belts move towards relative direction, after loosing one's grip, the pulling force between two belts is kept by ratchet device (Fig. 5).The knob conjuncted (11) of ratchet device is coaxial with the gear conjuncted (9) of band carry-over bar, there is the slewing area (the medium and small triangle of Fig. 5) that little each other, the band period of the day from 11 p.m. to 1 a.m unscrewed by knob, mechanism can utilize this slewing area go to pull open or press off ratchet (10) depart from ratchet corresponding determine ratchet (8), after loosing one's grip, ratchet can elasticity recover.
Simple ratchet device one reed (2) substitutes ratchet, the gear wheel (5) (similar ratchet) that the diameter that elasticity hinders and gear is fixed together is much bigger.Due to the effect of moment, the little power of a suitable reed energetically of tooth bar, after loosing one's grip, the power of elastic spring is enough to the tension force keeping wearing needs.Gear wheel, directly as knob, also can separately do concentric discs and make knob on gear is conjuncted.And hand dials gear wheel or the knob that be linked togather larger than gear wheel diameter, that resistance of reed is insignificant again.
Simpler mode directly stops pinion rotation with a toggle switch exactly, and switch comprises push-and-pull gear, makes gear move axially to the position of a restriction rotation.
2. buckle belt is connected by buckle with head-wearing display device, buckle (6) distribution buckle and hook buckle, and pin card button injects cutting ferrule (7) and connects, and hooks buckle and catches on cutting ferrule connection.
Claims (5)
1. the belt governor motion of a head-wearing display device, comprise head-wearing display device and wear belt, it is characterized in that: head-wearing display device increases tooth bar on joined belt, the tooth bar of one end belt is arranged on the top of gear, the tooth bar of other end belt is arranged on the below of gear, twists gear by knob, and two belt relative directions move, after loosing one's grip, the pulling force between two belts is kept by ratchet device.
2. the belt governor motion of head-wearing display device according to claim 1, it is characterized in that: the straightforward procedure of described ratchet device substitutes ratchet with a reed, elasticity hinders the gear wheel be fixed together with gear, gear wheel, directly as knob, also can separately do concentric discs and make knob on gear is conjuncted.
3. the belt governor motion of head-wearing display device according to claim 1, it is characterized in that: described ratchet device is: knob is coaxial with the gear of band carry-over bar, there is a running clearance each other, the band period of the day from 11 p.m. to 1 a.m unscrewed by knob, mechanism can utilize this running clearance, by knob conjuncted go to pull open or press off gear conjuncted on ratchet depart from ratchet corresponding determine ratchet.
4. the belt governor motion of head-wearing display device according to claim 1, it is characterized in that: described ratchet device also comprises and directly stops pinion rotation with a toggle switch, switch comprises push-and-pull gear, makes gear move axially to the position of a restriction rotation.
5. the belt governor motion of head-wearing display device according to claim 1, is characterized in that: described head-wearing display device is connected by buckle with between belt, and buckle has pin card button and hooks buckle, and pin card button injects cutting ferrule and connects, and hook buckle catches on cutting ferrule and connects.
