Abstract
The utility model discloses a shoulder guide ring of a safety belt. The shoulder guide ring of the safety belt comprises a support portion and a rolling portion which is fixed on the support portion. The support portion comprises a support framework and a coating layer which is covered on the support framework. The rolling portion comprises a rolling shaft and a rolling wheel which is arranged on the rolling shaft, two end portions of the rolling shaft are fixed on the support framework through fasteners, and the rolling wheel rolls on the rolling shaft through a rolling bearing. The rolling portion is arranged on the shoulder guide ring, so that sliding frication between the a braid and the shoulder guide ring is transferred to rolling friction, friction between the braid and the shoulder guide ring is reduced, and influence of the friction on comfort and safety is reduced.
Description
Technical field
The utility model relates to a kind of guide ring, relates in particular to a kind of safety strap shoulder guide ring.
Background technology
Safety strap shoulder guide ring is a vitals of car belt, at first will pass through the shoulder guide ring after the ribbon of safety strap is pulled out from taking-up device, and described shoulder guide ring makes the ribbon trend towards the only change in location of people's shoulder.As shown in Figure 1, the shoulder guide ring of existing safety strap is integral type mechanism, the occupant uses this safety strap shoulder guide ring normal operating condition as shown in Figure 2, ribbon will form sliding friction pair with guide ring, the friction force f of its generation can make when pulling out safety strap effort and slow when reclaiming, and has reduced comfort.When crashing, the tensile force f of safety strap makes ribbon sharply increase the positive pressure of guide ring, and the stack of the friction force f of its generation and belt force makes safety strap constantly increase the compressing power of human chest even causes the chest injury, has reduced safety.
The utility model content
For the problem that prior art exists, the purpose of this utility model provides a kind of safety strap shoulder guide ring, and it can be converted into friction of rolling with the interaction friction between ribbon and the guide ring, thereby improves traveling comfort and the safety of using.
Technical purpose of the present utility model realizes by technique scheme:
A kind of safety strap shoulder guide ring comprises the support portion and is fixed on rolled portion on the described support portion, wherein,
Described support portion comprises support frame and is coated on the outer integument of described support frame;
Described rolled portion comprises roller bearing and is arranged on roller on the described roller bearing, and the both ends of described roller bearing are fixed on the described support frame by fastener, and described roller rotates at described roller bearing by antifriction-bearing box.
Further, the both ends of described roller bearing are fixed by screws on the described support frame.
Further, described support portion is equipped with decorative cover in the fixed position of described fastener.
Further, described antifriction-bearing box is the cylindrical roller bearing.
Further, two of described roller ends are provided with seal ring.
Further, described integument is made by polyformaldehyde resin.
The utility model is converted into friction of rolling by at described guide ring rolled portion being set with the cliding friction between ribbon and the guide ring, has reduced the friction force between ribbon and the guide ring, has reduced the impact of friction force on comfort and safety.

The specific embodiment
Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is described in detail.
Shown in Fig. 3-5, the utility model provides a kind of safety strap shoulder guide ring, comprise support portion 1 and be fixed on rolled portion 2 on the described support portion 1, wherein, described support portion 1 comprises support frame 11 and is coated on the outer integument 12 of described support frame, described support frame is preferably made by the metallic material with some strength, for example corrosion-resistant steel.The Main Function of considering described integument 12 is to prevent from making metallic support skeleton scratch occupant, the integument of the present embodiment is preferably made by polyformaldehyde resin, certainly, the utility model can also adopt suitable wrapper material known in those skilled in the art to make.
Described rolled portion 2 comprises roller bearing 21 and is arranged on roller 22 on the described roller bearing 21, the both ends of described roller bearing 21 are fixed on the described support frame by fastener 23, the present embodiment preferably selects screw as fastener, certainly the utility model can also adopt described other the familiar fastener of those skilled in the art, for example rivet.In order to prevent fastener scratch occupant, decorative cover 13 is also preferably installed in the position of described fastener in the support portion of the present embodiment, and described decorative cover can be made by polyformaldehyde resin.Described roller 22 rotates at described roller bearing 21 by antifriction-bearing box 24, described antifriction-bearing box is preferably the cylindrical roller bearing, described cylindrical roller bearing contacts or repaiies the contact of rolling off the production line with roller bearing 21 for line, radially load-carrying capacity is large, can bear heavy load and impact load, and described cylindrical roller bearing can move axially, and therefore can adapt to the variation of the roller bearing 21 that causes because of het expansion or installation error and roller 22 relative positions.The two ends of the roller of the present embodiment also preferably are provided with seal ring 25, and seal ring 25 provides the leak tightness protection for antifriction-bearing box, improve useful life longevity.
During installation, metallic framework 11 is made integral structure with the polyformaldehyde resin injection moulding, roller 22 and roller bearing 21 are connected together by rolling bearing 24, the two ends of described roller adopt seal ring 25 sealings to form rolled portion 2 again, then utilize screw 3 that rolled portion 2 is connected on the support portion 1, decorative cover 25 is installed above screw 3 at last.Pulling ribbon during use, ribbon drives rolled portion and rolls, thereby the cliding friction between ribbon and the guide ring is converted into friction of rolling, reduces friction, thereby improves comfort and safety.
Above-described embodiment is only for illustration of the utility model; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; in the situation that do not break away from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all equivalent technical solutions also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
