Description

Hand pram

The utility model relates to a kind of perambulator for children's use.

Hand propelled perambulator of the prior art, its vehicle frame part are flexibly connected with the arm-rest frame intersection that is " U " font by the pushing hands frame that is " U " font and form, and two sides of vehicle frame all are " X " shape.Back rest is installed on vehicle frame, back cushion is installed on the back rest, the below of hand push frame is equipped with front-wheel, and the below of arm-rest frame is equipped with trailing wheel.The vehicle frame side of this perambulator is because of being " X " type, so pushing hands frame and arm-rest frame can be around its active connection place rotations, the vehicle frame that pushing hands frame and arm-rest frame are formed launches or shrinks, and needs location and folding device, existing folding and positioning device structure complexity, very inconvenient during use.

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of folding and registration device simple in structure is provided, and forms a kind of hand propelled perambulator easy to use.

The purpose of this utility model can realize by following technical proposal:

Vehicle frame part of the present utility model is flexibly connected with the arm-rest frame intersection that is " U " font by the pushing hands frame that is " U " font and forms, back rest rotatably is installed on vehicle frame, back cushion removably is installed on the back rest, and this back cushion can be sat, crouch for children.The below of pushing hands frame is equipped with front-wheel, and the below of arm-rest frame is equipped with trailing wheel; The spacing band two ends that make the below of pushing hands frame and arm-rest frame cross connection place, flexible material are separately fixed on pushing hands frame and the arm-rest frame, and this spacing band can make pushing hands frame and arm-rest frame just locate after its junction rotates to a certain degree; The below of pushing hands frame and arm-rest frame cross connection place, rotatably be positioned with locking stop on the pushing hands frame, mutually perpendicular two faces are arranged on the described locking stop, the following side contacts of face and arm-rest frame, make pushing hands frame and arm-rest frame not to draw in around its junction rotation, the outer side contacts of another face and arm-rest frame is as the confined planes when the pushing hands frame rotates of locking stop; The below of arm-rest frame is fixed with back bag rack, and the back pocket is installed on the back bag rack; The below of back rest, be lower than on the pushing hands frame of junction of vehicle frame and back rest and rotatably be provided with the backrest angle adjust bar, have on the described backrest angle adjust bar one with the bending section of the S. A. decentraction of backrest angle adjust bar, the following side contacts of this bending section and back rest, and be positioned at the framework of the adjust bar position-limited rack that is fixed on the back rest.Described bending section can be pressed the radius rotation of bending section around the axle center of back rest adjust bar, because the following side contacts of bending section and back rest, thus can promote the junction rotation of back rest around itself and vehicle frame, thus make the adjustable angle of back rest.

The utility model compared with prior art has following advantage:

Because spacing band and locking stop have been installed between pushing hands bar and grab rail, spacing band is spacing after vehicle frame is launched, and is spacing when locking stop can make vehicle frame draw in, so the vehicle frame part is relatively stable, simple in structure, easy to use.Back rest can adjusting angle, can select the angle of the most comfortable for children.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing is the three-dimensional structure diagram after the utility model removes back cushion, wherein:

1. pushing hands frame; 2. back rest; 3. arm-rest frame; 4. locking stop; 5. back bag rack; 6. backrest angle adjust bar; 7. pocket after; 8. front-wheel; 9. adjust bar handle; 10. spacing band; 11. trailing wheel; 12. adjust bar position-limited rack.

With reference to accompanying drawing, vehicle frame part of the present utility model is flexibly connected with the arm-rest frame 3 usefulness rivets intersection that is " U " font by the pushing hands frame 1 that is " U " font and forms, and is connected with back rest 2 with rivet on vehicle frame, and back rest 2 can be around its junction rotation.Be with back cushion on the back rest 2, the back cushion top is provided with tilt.The below of last pushing hands frame 1 is equipped with the front-wheel 8 that can turn to, and the below of arm-rest frame 3 is equipped with trailing wheel 11; The below of pushing hands frame 1 and arm-rest frame 3 cross connections place, spacing 10 two ends of being with made from the nylon belt are separately fixed on pushing hands frame 1 and the arm-rest frame 3; The below of pushing hands frame 1 and arm-rest frame 3 cross connections place, can be positioned with locking stop 4 on the pushing hands frame 1, this position block can have mutually perpendicular two faces around its place, location rotation on the described locking stop 4, the following side contacts of face and arm-rest frame 3, the outer side contacts of another face and arm-rest frame 3; The another kind of installation method of locking stop is that the locking stop 4 of pushing hands frame 1 and arm-rest frame 3 cross connections place below also can rotatably be positioned on the arm-rest frame 3, mutually perpendicular two faces on the described locking stop 4, the following side contacts of face and pushing hands frame 1, the outer side contacts of another face and pushing hands frame 1.The below of arm-rest frame 3 is fixed with back bag rack 5 with rivet, and this back bag rack 5 can be around its junction rotation so that draw in; Back pocket 7 is installed on the back bag rack 5; The below of back rest 2, be lower than on the pushing hands frame 1 of junction of vehicle frame and back rest 2 and be fixed with backrest angle adjust bar 6 with rivet, this backrest angle adjust bar 6 can be around the rotation of the junction of itself and pushing hands frame 1, also has adjust bar handle 9 on the backrest angle adjust bar 6, described adjust bar handle 9 is positioned at the outside of pushing hands frame 1, is 90 degree bendings with backrest angle adjust bar 6; Have on the described backrest angle adjust bar 6 one with the bending section of the S. A. decentraction of backrest angle adjust bar 6, this bending section withstands on the downside of back rest 2, and is positioned at the framework of the adjust bar position-limited rack 12 that is fixed on the back rest 2.Described adjust bar position-limited rack 12 is " U " font, the two ends of its opening are weldingly fixed on the downside of back rest 2, one end of adjust bar position-limited rack 12 is fixed on the radius of rotation inboard of the bending section of backrest angle adjust bar 6, and the other end of adjust bar position-limited rack 12 is fixed on the radius of rotation outside of the bending section of backrest angle adjust bar 6.
