Detailed Description

The technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments described herein without the need for inventive work, are within the scope of the present invention.

An embodiment of the invention provides a portable restraint system, as shown in fig. 1 to 16, the portable restraint system comprises a seat body 1, wherein the seat body 1 is rotatably connected with a buckle 2 through a rotating shaft 31, and a torsion spring 5 is connected between the buckle 2 and the seat body 1.

The rotating shaft 31 is fixedly connected with a rotating plate 3, a torsion spring 5 is connected between the rotating plate 3 and the seat body 1, and the rotating plate 3 is fixedly connected with the buckle 2.

The seat body 1 is provided with an opening 51 for rotating the buckle 2 and the rotating plate 3 within a predetermined rotation angle. The provision of the opening 51 ensures that the clasp 2 and the rotary plate 3 rotate within a predetermined angle of rotation.

The rotating plate 3 is provided with a first through hole 6, the lower surface of the seat body 1 is provided with a plurality of baffles 11, the baffles 11 are provided with second through holes 7, and a torsion spring 5 is connected between the first through hole 6 and the second through holes 7.

The number of the baffles 11 is two, the baffles 11 are oppositely arranged, a second through hole 7 is formed in each baffle 11, two first through holes 6 are formed in the rotating plate 3, the number of the torsion springs 5 is two, one ends of the torsion springs 5 penetrate through the first through holes 6, and the other ends of the torsion springs 5 penetrate through the second through holes 7. Wherein, the design of two torsional springs 5 has guaranteed that rotor plate 3 and buckle 2 can relatively stable rotation.

And the baffle 11 is also fixedly connected with a limiting baffle 8 for limiting the rotation of the rotating plate 3 and the torsion spring 5 in a preset rotation angle. The arrangement of the limit baffle 8 can limit the rotation angle of the rotating plate 3, so that the rotating plate 3 can rotate to the innermost position state or the outermost position state conveniently.

Wherein the predetermined rotation angle range is preferably 120 ° -150 °.

The upper surface of the seat body 1 is provided with an inward concave groove 9 or an outward convex base 4, and the groove 9 or the base 4 is provided with limiting holes 10 for the two ends of the rotating shaft 31 to extend into.

Wherein the number of the bases 4 or the grooves 9 is 2, which are respectively arranged oppositely, and the rotating shaft 31 is installed by the action of the limiting hole 10, thereby facilitating the rotation of the rotating shaft 31.

The groove 9 is more in line with human engineering, and when a child sits on the seat, the legs of the child cannot be placed on the base 4, and the seat is more comfortable.

Buckle 2 is in innermost position state or outermost position state, and when embracing child and getting into seat body 1, drive power and torsional spring 5 combined action down the drive buckle 2 rotates and makes buckle 2 be in innermost position state, and when embracing child and going out seat body 1, drive power and torsional spring 5 combined action down the drive buckle 2 gyration makes buckle 2 be in outermost position state.

The method comprises the following specific operation steps: in the initial state, the rotating plate 3 and the buckle 2 are in the outermost position state, as shown in fig. 6 and 10, when a user holds a child in the child seat, the buckle 2 and the rotating plate 3 are rotated by a clockwise force, even if the clockwise force is small, once the buckle 2 rotates over a vertical plane, the rest rotation of the buckle 2 can be completed under the action of the torsion spring 5, and at the moment, the rotating plate 3 and the buckle 2 are in the innermost position state, as shown in fig. 5 and 9; in a similar way, when the user embraces child's seat out, in the same place as power with buckle 2 and rotor plate 3 rotation, even the force of taking the same place is less, in case buckle 2 has rotated vertical plane, 2 remaining rotations of buckle can be accomplished under the effect of torsional spring 5, at this moment, rotor plate 3 and buckle 2 are in outermost position state, ingenious utilization has embraced the force of taking the same place when advancing and embracing child out as drive power to supplement as the drive through torsional spring 5, accord with practical scene more.

Certainly, the user can also rotate the buckle 2 manually to drive the rotating plate 3 to rotate, so that the rotation of the buckle 2 is realized.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
