Manual

Adjustable Retractor

Technical Field

The utility model relates to safety belt equipment, in particular to an adjustable retractor.

Background Technique

The retractor is mainly used for winding and retracting the seat belt. The structure of one of the retractors mainly includes a belt winding shaft, the safety belt is wound on the belt winding shaft, a ratchet wheel is connected to the belt winding shaft, and a swing piece that can cooperate with the ratchet wheel to be pressed is arranged on the mounting frame. , when the safety belt is completely wound on the belt winding shaft, the safety belt will squeeze the contact protrusion on the swing piece, drive the swing piece to swing, so that the swing piece and the ratchet are staggered, and the safety belt can be easily pulled out at this time, and As the seat belt is pulled out, the radius of the coiled seat belt becomes smaller, and the swinging member will swing under the action of the elastic member, so that the swinging member will be stuck with the ratchet, thereby ensuring the locking of the seat belt, but due to the contact convex However, the actual pull-out amount of the seat belt required by different models or usage scenarios will vary to a certain extent. It is necessary to set up swing parts of different specifications, which leads to poor generality of its use.

SUMMARY OF THE INVENTION

In view of the deficiencies of the background technology, the technical problem to be solved by the present invention is to provide a retractor with a simple structure and a reasonable design, which can adjust the initial pull-out amount of the seat belt according to different vehicle models and usage environments.

For this reason, the utility model adopts the following scheme to realize:

The adjustable retractor includes a mounting frame on which a tape winding shaft is rotatably arranged, one end of the tape winding shaft is connected with a coil spring, and both sides of the tape winding shaft are connected with a ratchet, A swinging piece is arranged on the mounting frame, the swinging piece is connected with the first elastic reset piece, and the swinging piece is provided with a convex part that can cooperate with two ratchets to be pressed, and it is characterized in that it also includes a limiter A swing arm, the middle part of the limit swing arm is hinged on the swing piece, a first spring is tightly pressed between one end of the limit swing arm and the swing piece, and the swing piece is provided with a limiter The limit protrusion against which the swing arm is opposed, the mounting bracket is arranged in the outer casing, and the outer casing is screwed with an adjustment bolt, and the adjustment bolt can be pressed against the limit swing arm.

The first elastic reset member is a first torsion spring, one end of the first torsion spring is connected with the first connecting hole opened on the swinging member, and the other end is connected with the second connecting hole opened on the mounting frame.

The outer casing includes a casing body, and the casing body has a flip cover, and one end of the flip cover is provided with a cylindrical insert block on the left and right sides, and both the casing body and the mounting frame are provided with a cylindrical plug for the cylindrical plug. The jack through which the block passes.

By adopting the above technical scheme, the utility model has the advantages of simple structure, reasonable design, convenient production and processing, the limit swing arm is hinged on the swing piece, and the limit swing arm can be easily adjusted by adjusting the rotation angle of the limit swing arm The distance between the belt winding shaft and the retractor seat belt can be adjusted to adjust the initial pull-out amount of the retractor seat belt, which can effectively adapt to different models and usage scenarios, and improve the versatility and flexibility of its use.

Description of drawings

The utility model has the following accompanying drawings:

Figure 1 is a schematic structural diagram of the utility model.

Detailed ways

As shown in the figure, the adjustable retractor disclosed by the utility model includes a mounting frame 15, on which a tape winding shaft 9 is rotatably arranged, and one end of the tape winding shaft 9 is connected with a coil spring, and the tape winding shaft Both sides of 9 are connected with a ratchet 8, and a swinging member 6 is arranged on the mounting frame 15, and the swinging member 6 is connected with the first elastic restoring member. In this embodiment, the first elastic restoring member is the first torsion spring 12, and the first elastic restoring member is One end of a torsion spring 12 is connected to the first connection hole 11 formed on the swinging member 6 , and the other end is connected to the second connection hole 10 formed on the mounting frame 15 . The swinging member 6 is provided with a raised portion 7 that can cooperate with the two ratchets 8 to be pressed, and also includes a limit swing arm 5. The middle of the limit swing arm 5 is hinged on the swing member 6, and one end of the limit swing arm 5 is hinged. A first spring is tightly pressed with the swinging member 6, and the swinging member 6 is provided with a limiting protrusion 4 that can be abutted against the limiting swing arm 5. Since the first spring presses the bottom of the limiting swing arm 5, Therefore, in the figure, the first spring is shielded by the limit swing arm 5 , the mounting frame 15 is arranged in the outer casing, and the outer casing is screwed with adjustment bolts 2 , and the adjustment bolt 2 can be pressed with the limit swing arm 5 . Specifically, the outer casing 3 includes a casing body 3, the casing body 3 has a flip cover 1, one end of the flip cover 1 is provided with cylindrical plugs 14 on the left and right, and the casing body 3 and the mounting frame 15 are provided with cylindrical plugs for supplying The insertion hole 13 through which the plug 14 passes is convenient for positioning and assembling after the flip cover 1 is closed.

The retractor of the utility model has the advantages of simple structure, reasonable design, and convenient production and assembly. When the bolt 2 is separated from the limit swing arm 5, the limit swing arm 5 rotates to an angle that counteracts the limit protrusion 4 under the action of the first spring. At this time, the distance between the top of the limit swing arm 5 and the tape winding shaft 9 is the smallest , when the seat belt is completely wound on the belt winding shaft, the swing angle of the squeeze swing member 6 is the smallest, that is, the initial pull-out amount of the seat belt is the smallest, and the swing member 6 will be driven by the first torsion spring 12 and the ratchet 8 . According to different models, the adjustment bolt 2 can be controlled to rotate, the bottom end of the limit swing arm 5 can be squeezed to make the limit swing arm rotate, and the distance between the top of the limit swing arm and the tape winding shaft 9 can be adjusted. Thus, the initial pull-out amount of the seat belt is effectively adjusted, and the versatility and flexibility of its use are improved.
