Description
Technical field
The utility model relates to safety strap and tightens up field, refers to especially a kind of safety belt locking-type structure.
Background technology
As everyone knows; safety strap is to ensure the requisite device of personal security by bus; that ribbon by pulling out from reel is fixed on the personnel of riding seat; while there is the emergency episodes such as shock when vehicle, can play protection passenger's effect, while arriving end due to the quick backrush of ribbon in prior art; run into rigid pipe cut; band sense escapement on reel axle is lifted under large force of inertia effect, produce locking with locking lid, ribbon can not be pulled out.Cause safety strap normally not use, inconvenient operation.
At present, solution to the problems described above mainly contains two kinds; 1, reduce to furl power, make ribbon backrush speed slack-off, when running into rigid pipe in the time of endways and stopping, the inertia of band sense escapement is relatively little, is difficult for locking; 2, strengthen band sense pressure spring force value, make band sense be tending towards the upper limit of locking locking scope, be difficult for producing locking.But above-mentioned two schemes is all merely able to the probability that minimizing problem occurs, and can not evade this type of phenomenon completely.
Utility model content
The purpose of this utility model is to provide a kind of safety belt locking-type structure, when this structure can meet ribbon backrush to end, safety strap band sense function is closed automatically, when occupant wears safety strap, safety strap band sense function is opened automatically, to evade defect of the prior art completely, improve safety strap comfort, easy to use.
To achieve these goals, the utility model has adopted following technical scheme: a kind of safety belt locking-type structure, comprise taking-up device, the mandrel of described taking-up device connects an escapement by gear transmission, described escapement is provided with the briquetting coordinating with escapement, and described escapement is provided with a limited post, and described briquetting is sector structure, its outer arc is bent downwardly and forms one for suppressing the place-limited edge of limited post, described escapement and briquetting coaxial line.
Further, connect a core sleeve rotating with mandrel on described taking-up device mandrel, described core sleeve is by spline joint one driving tooth, and this driving tooth driving cog that is connected with a joggle, connects a driven gear on this driving cog.
Further, described limited post contacts with place-limited edge, and escapement is pressed, and the anti-lock function of band sense is opened.
Further, described limited post is separated with place-limited edge, and escapement lifts generation locking, and the anti-lock function of band sense closes.
Further, have an auxiliary tooth for one-body molded and coaxial line with it on described briquetting, this auxiliary tooth is meshed with driven gear.
Further, the described briquetting rotation that matches with core sleeve by a centre hole.
Further, also comprise a locking lid, described driving tooth, driven gear, driving cog are all installed on described locking lid.
The beneficial effects of the utility model are: adopt after said structure, safety strap band sense function can automatically be closed or open with the stretching of ribbon, and before occupant wears safety strap, band sense function is closed, and now locking does not occur safety strap; Occupant, wear after safety strap, safety strap starts band sense function automatically, and protection occupant safety has been avoided the defect that ribbon inertia is large and locking locking can not be pulled out, easy to use.

In figure: taking-up device 1, mandrel 11, core sleeve 12, escapement 2, limited post 21, briquetting 3, place-limited edge 31, auxiliary tooth 32, driving tooth 4, driven gear 5, driving cog 6.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1～5, a kind of safety belt locking-type structure, comprise taking-up device 1, this taking-up device 1 is for being wound around ribbon, and the mandrel 11 of described taking-up device 1 connects an escapement 2 by gear transmission, and described escapement 2 is provided with the briquetting 3 coordinating with escapement 2, described escapement 2 is provided with a limited post 21, described briquetting 3 is sector structure, and its outer arc is bent downwardly and forms one for suppressing the place-limited edge 31 of limited post 21, described escapement 2 and briquetting 3 coaxial lines.
The utility model is mainly used in vehicle safety belt and conveniently furls, and safety strap band sense function can automatically be closed or open with the stretching of ribbon, and before occupant wears safety strap, band sense function is closed, and now locking does not occur safety strap; Occupant, wear after safety strap, safety strap starts band sense function automatically, and protection occupant safety has been avoided the defect that ribbon inertia is large and locking locking can not be pulled out, easy to use.
On described taking-up device 1 mandrel 11, connect a core sleeve 12 rotating with mandrel 11, described mandrel 11 1 ends have claw portion, between Qi Yu core sleeve 12, pass through claw clamping, the other end of described core sleeve 12 is by spline joint one driving tooth 4, this driving tooth 4 driving cog 6 that is connected with a joggle, connects a driven gear 5 on this driving cog 6, mutually transferring power, on described briquetting 3, have an auxiliary tooth 32 for one-body molded and coaxial line with it, this auxiliary tooth 32 is meshed with driving cog 6.Described core sleeve 12 is a moulding.
With reference to Fig. 1, Fig. 2, the rotation of taking-up device 1 drives core sleeve 12 to rotate, and core sleeve 12 drives driving tooth 4 to rotate, and driving tooth 4 drives driving cog 6 to rotate, and driving cog 6 drives driven gear 5 to rotate, and the rotation of driven gear 5 drives briquetting 3 rotations.When briquetting 3 place-limited edges 31 rotate the region to escapement 2 limited posts 21 contacts, escapement 2 can not lift generation locking, the anti-lock function on of band sense, and band sense can not locking.Now, ribbon can locking; When briquetting 3 place-limited edges 31 and escapement 2 limited posts 21 are when separated, now escapement 2 can lift generation locking, and the anti-lock function of band sense does not start, and band sense latch functions is normal, and ribbon is by locking.Like this, by the transmission of this train of gears, realized the automatic open and close of being controlled band sense function by braided strap winding length, this train of gears drive mechanism also available other structures of the prior art substitutes.
With reference to Fig. 5, the arc length of briquetting 3 place-limited edges 31 has determined escapement 2 and the length that briquetting 3 contacts, and is the length that prevents ribbon locking, therefore, at the actual Che Shiying of joining, according to vehicle, carrys out the corresponding arc length of adjusting place-limited edge 31.
The rotation that matches with core sleeve 12 by a centre hole of described briquetting 3.Briquetting 3 matches with an axle in core sleeve 12 by a centre hole, and relative rotational motion is done by Qi Kerao core sleeve 12.
In order to guarantee that this structure can be stablized, be arranged at taking-up device 1, the utility model also comprises a locking lid, described driving tooth 4, driven gear 5, driving cog 6 are all installed on described locking lid, and this locking lid is connected on the support of described taking-up device 1 by the Access Division at its edge.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
