Abstract
The utility model relates to a ratchet is the amortization ratchet of impact sound between a reducible pawl that is used for on the car safety straining device and the ratchet teeth. It includes ratchet and amortization pad, this amortization spacer have with the ring portion of ratchet side laminating and the cusp convex part that covers the ratchet tooth root, the gomphosis is in the ratchet tooth's socket one by one for amortization pad and ratchet combination back cusp convex part, and the periphery of ring portion is less than the prong of ratchet and makes the prong expose. Through at ratchet facial make -up amortization pad, make the tooth root of ratchet have the amortization pad to cover, when the pawl falls into the tooth root from the tooth top, pawl and cushion contact, the acoustic phase is slighter than very, the great sound of metallic sound striking can not appear to reach the mesh of amortization.
Description
Technical field
This utility model is related to a kind of ratchet, more particularly, to a kind of reduced spine on vehicle safety tensioning device
The noise reduction ratchet of strike note between pawl and hook tooth.
Background technology
Ratchet, active ratchet on conventional vehicle safety tensioning device, detent are metal class hard material and make.
During work, ratchet is along hook tooth action, driving pawl or stop gear.When ratchet abruptly enters ratchet tooth root from hook tooth top
When, clash into and produce larger noise, as shown in Figure 6.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of for automotive safety tension for prior art
The noise reduction ratchet of device, to reduce the strike note between ratchet and ratchet.
This utility model solve the technical scheme that adopted of above-mentioned technical problem for:The noise reduction ratchet, including ratchet, it is special
It is also to include silencing pad to levy, and the silencing pad has the dentation of the annular portion and covering ratchet tooth root fitted with ratchet side convex
Portion, dentation convex portion is entrenched in one by one in ratchet teeth groove after described silencing pad is combined with ratchet, and the periphery of annular portion is less than spine
The crown of wheel exposes crown.
The structure of split or one can be adopted between described silencing pad and ratchet, split type is described noise reduction single pad
Solely make, both adopt detachable combinative structure, described silencing pad to have the annular portion of one side of laminating ratchet, tooth
Shape convex portion is distributed in the side of annular portion, along the projection of annular portion neighboring.
Integral type is that described silencing pad is integrally formed using plastic technique with ratchet, and described silencing pad has two points
Not Tie He ratchet two sides annular portion, have described dentation convex portion to be connected between two annular portions.
Described ratchet center carries through hole, and the central through hole of the silencing pad annular portion can not be less than ratchet center
Through hole, does not so interfere with the normal mounting of vehicle safety tensioning device take-up spool.
Described ratchet central through hole is two symmetrical semi-circular through hole, with the take-up spool phase being made up of two halves circular shaft
Match somebody with somebody.
Compared with prior art, the utility model has the advantage of:By filling silencing pad on ratchet, the tooth root of ratchet is made
There is silencing pad to cover, when ratchet falls into tooth root from tooth top, ratchet is contacted with cushion, sound is compared very slightly, is not in
The relatively loud noise that metallic sound clashes into, so as to reach the purpose of noise reduction.

Specific embodiment
This utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figure 1, 2, the ratchet 1 of the present embodiment noise reduction ratchet and silencing pad 2 are Split type structure to embodiment one, silencing pad
2 is separately made with plastics soft material.The silencing pad 2 have an annular portion 21 and be distributed in annular portion side, along annulus
The dentation convex portion 22 of portion neighboring projection, annular portion 21 is fitted with the one side of ratchet 1, central through hole 23 thereon and ratchet
On through hole 13 it is corresponding, and the central through hole 23 in annular portion can not be less than ratchet on central through hole 13, so can ensure that
The normal mounting of vehicle safety tensioning device take-up spool 3 and work.And the central through hole 23 on ratchet is two symmetrical semicircles
Shape through hole, it matches with the take-up spool 3 being made up of two halves circular shaft.Dentation convex portion 22 corresponds the teeth groove 11 on ratchet,
After silencing pad 2 is combined with ratchet 1, the correspondence of dentation convex portion 22 is embedded in the teeth groove 11 on ratchet, by each tooth root on ratchet
Cover, and the periphery of annular portion 21 exposes crown 12 less than the crown 12 of ratchet, makes ratchet 1 coordinate ratchet normal work.
After this noise reduction ratchet is attached on main frame, because there is spacing (as shown in Figure 6) of handle lateral plate and base lateral plate both sides,
Closing the silencing pad 2 on ratchet 1 can't come off from ratchet 1.Therefore the ratchet 1 of the present embodiment is that employing can with silencing pad 2
Detached combination, without the need for being fixed using alternate manner.
As shown in Figure 3,4, its difference with embodiment one is the ratchet 1 and silencing pad 2 of this noise reduction ratchet to embodiment two
One has been made using plastic technique, it is inseparable.Also different from embodiment one, it has two annulus to the structure of silencing pad 2
Portion 21, is respectively coated by two sides of ratchet 1, and is connected by dentation convex portion 22 between two annular portions 21, each dentation convex portion
22 coat one by one the tooth root of ratchet 1.
Claims (5)
