Abstract
The utility model discloses a two-point type self-locking safety belt, and relates to an automobile safety device. The two-point type self-locking safety belt comprises a retractor, wherein the retractor comprises a wheel shaft sleeve; the wheel shaft sleeve is a hollow annular body with an opening in the side surface; the wheel shaft sleeve comprises a first side end and a second side end; smoothing mechanisms are arranged at the first side end and the second side end. Compared with the prior art, the smoothing mechanisms are arranged at the first side end and the second side end of the wheel shaft sleeve, so that the height difference formed by the wheel shaft sleeve is reduced; therefore, after a braid of the safety belt winds the wheel shaft sleeve around a circle, the wheel shaft sleeve is in a shape of a circle approximately, and the working performance of the retractor is guaranteed; the phenomenon that the tensile strength of an assembly is reduced due to a fact that the braid is cut off by a corner angle of the wheel shaft sleeve is also avoided, so that the use performance of the automobile safety belt is guaranteed.
Description
Technical field
The utility model relates to a kind of auto-safety mechanism, especially a kind of car belt.
Background technology
Car belt is exactly the device for ensure that passenger and chaufeur prevent that in the time that vehicle body is subject to clashing passenger from being ejected by safety air bag time injury on automobile.The speed of modern automobile is very fast, once bump, vehicle body stop motion, and passenger's body is because inertia can move forward, and in Che Nei and vehicle body strikes, when serious, Windshield may be crashed and fly out forward outside window.Similarly injury occurs when preventing from colliding, and public security department requires small-sized bus man and front-seat passenger to use of seat belts, so that while there is traffic accident, the effect that safety strap plays buffering to people, prevents secondary injury.On high-grade car, except front, back row seats have outside safety strap, and air bag system is also installed, once get into an accident, air bag will eject by automatic inflating, and people is not bumped against on vehicle body.
The safety strap that most of automobile uses generally includes taking-up device, guide ring, ribbon and snap close, wherein taking-up device is to be combined by spool and axle sleeve, one end of ribbon is just fixed in taking-up device, the axle sleeve of taking-up device is generally discontinuous ring bodies now, the corner angle of its end face are generally wedge angle, such structure is easy to the ribbon cutoff in taking-up device, thereby causes assembly tensile strength step-down.Because axle sleeve is the ring bodies with corner angle, it is not a circle that ribbon is wound around a circle in the above, can affect the serviceability of taking-up device in addition, and then affects the in-use performance of safety strap.
Summary of the invention
The utility model is for deficiency of the prior art, a kind of two-point form passive belt is provided, the end face of axle sleeve in taking-up device is arranged to arc transition mechanism, has solved the ribbon in taking-up device in prior art and easily cut off, thereby cause the problem of assembly tensile strength step-down.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: comprise taking-up device, described taking-up device comprises axle sleeve, described axle sleeve is the ring bodies on inner hollow and side with opening, described axle sleeve comprises first side and second side, and described first side and described second side are provided with level and smooth mechanism.The side end face in axle sleeve is like this provided with the structure of level and smooth mechanism, reduced the high low head that axle sleeve forms, thereby the ribbon of safety strap is wound around in axle sleeve after a circle, is approximately a circle, has ensured the serviceability of taking-up device.
In order to obtain better technique effect, further technological improvement also comprises, the level and smooth mechanism of described axle sleeve first side is that end face is arranged to arc transition structure, and two corner angle that the level and smooth mechanism of described axle sleeve second side is end face are all arranged to rounding.Such setting, has avoided the corner angle of axle sleeve by the ribbon cutoff of safety strap, and then causes the situation of assembly tensile strength step-down.
Compared with prior art, the beneficial effects of the utility model are: because first side and the second side of axle sleeve are provided with level and smooth mechanism, reduce the high low head that axle sleeve forms, thereby the ribbon of safety strap is wound around after a circle in axle sleeve, be approximately a circle, ensured the serviceability of taking-up device, also avoided the corner angle of axle sleeve by ribbon cutoff, and then cause the situation of assembly tensile strength step-down, thereby ensure the in-use performance of car belt.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is partial schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
Shown in Fig. 1 and Fig. 2, a kind of specific embodiment of the present utility model.A kind of two-point form passive belt, comprises belt retractor fixing support 1, taking-up device 2, ribbon 3 and snap close 4.Taking-up device 2 is fixed on to be received in device fixed support 1, one end of ribbon 3 is fixed in taking-up device 2, and pass axle sleeve 21 in taking-up device, the other end of ribbon 3 is connecting snap close 4, described axle sleeve 21 is for having the ring bodies of opening on inner hollow and side, described axle sleeve 21 comprises first side 21a and second side 21b, described first side 21a and described second side 21b are provided with level and smooth mechanism, the level and smooth mechanism of described axle sleeve first side 21a is that end face is arranged to arc transition structure, two corner angle that the level and smooth mechanism of described axle sleeve second side 21b is end face are all arranged to rounding.
The utility model is because first side 21a and the second side 21b of axle sleeve 21 are provided with level and smooth mechanism, reduce the high low head that axle sleeve forms, thereby the ribbon of safety strap is wound around after a circle in axle sleeve, be approximately a circle, ensure the serviceability of taking-up device, also avoid the corner angle of axle sleeve by ribbon cutoff, and then caused the situation of assembly tensile strength step-down, thereby ensured the in-use performance of car belt.
Claims (2)
1. a two-point form passive belt, comprise taking-up device (2), it is characterized in that: described taking-up device (2) comprises axle sleeve (21), described axle sleeve (21) is for having the ring bodies of opening on inner hollow and side, described axle sleeve (21) comprises first side (21a) and second side (21b), and described first side (21a) and described second side (21b) are provided with level and smooth mechanism.
2. a kind of two-point form passive belt according to claim 1, it is characterized in that: the level and smooth mechanism of described axle sleeve first side (21a) is that end face is arranged to arc transition structure, two corner angle that the level and smooth mechanism of described axle sleeve second side (21b) is end face are all arranged to rounding.
