Detailed description of the invention
as shown in accompanying drawing 1-4, a kind of seat pocket be arranged on children trolley, is positioned at the back rest 2 at the rear portion at seat 1, the backrest railing 3 be arranged on back rest 2 when comprising seat 1, use.
the bottom, the left and right sides of back rest 2 and the left and right sides portion at seat 1 are around the first axle 11 pivotal joint, and seat pocket also comprises the rotary locking mechanism for locking between seat 1 and back rest 2.Rotary locking mechanism is the common technique in this area, and its concrete structure is not invention main points of the present utility model, as long as the structure locked between the parts that two can be rotated can be suitable at this, does not describe in detail.
backrest railing 3 is slidably arranged on back rest 2 along the short transverse of back rest 2, seat pocket also comprises along with back rest 2 changes thus the control mechanism of control backrest railing 3 movement relative to the angle at seat 1, when back rest 2 becomes large with the angle at seat 1, backrest railing 3 relatively back rest 2 stretches out, when back rest 2 diminishes with the angle at seat 1, backrest railing 3 back rest 2 indentation relatively, control mechanism connects seat 1 and backrest railing 3.
concrete, control mechanism comprises two bottoms and is pivotally connected in drive spindle 41 in the left and right sides portion at seat 1 around the second axle 42, and the upper end of each drive spindle 41 correspondingly turns with the both ends of backrest railing 3 and is rotationally connected around the 3rd axle 43 respectively.Second axle 42 is positioned at the back lower place of the first axle 11.The left and right sides portion of back rest 2 offers slot 21 along above-below direction respectively, the both ends of backrest railing 3 are inserted in slot 21, the left and right sides portion of back rest 2 offers the guide groove 22 be connected with corresponding slot 21 respectively, and the upper end of the drive spindle 41 of every side is connected with backrest railing 3 by guide groove 22.Seat 1, drive spindle 41, back rest 2 form the triangle mechanism that can slide and be out of shape with backrest railing 3.
as shown in Figure 2-4, after rotary locking mechanism is unlocked, rotate backward back rest 2, namely the angle adjusting angle a makes it become large, makes a pocket adjust to the process of lying posture from sitting posture, makes drive spindle 41 also be tending towards lying flat, back rest 2 is close to seat 1, backrest railing 3 relative back rest 2 under the support of drive spindle 4 is protruding, thus makes under lying posture state, and backrest railing 2 can not shorten; Otherwise when upwards rotating back rest 2, the angle namely adjusting angle a makes it diminish, and makes a pocket adjust to the process of sitting posture from lying posture, makes drive spindle 41 also be tending towards holding up, relative for backrest railing 3 back rest 2 pulls back by drive spindle 41.
embodiment two, as depicted in figures 5-8, embodiment two is with the difference of embodiment one: control mechanism comprises two one end portion and is not fixed on the soft bar 51 of driving in the left and right sides portion at seat 1, two drive the other end of soft bars 51 to be fixedly connected with the both ends of backrest railing 3 accordingly, drive the part of soft bar 51 around with the axle center of the first axle 11 for the center of circle circumferentially.Two drive the other end of soft bar 51 to be stretched out backward by the below of the first axle 11 respectively.The left and right sides portion of back rest 2 offers slot 21 along above-below direction respectively, and the both ends of backrest railing 3 are inserted in slot 21, and two drive being inserted in slot 21 of the partial response of soft bar 51 to be fixedly connected with the end of backrest railing 3.Soft bar 51 is driven to be spring steel or duroplasts.
as shown in accompanying drawing 6-8, after rotary locking mechanism is unlocked, rotate backward back rest 2, back rest 2 relative thereto 1 angle becomes large, a pocket is made to adjust to the process of lying posture from sitting posture, lacked part around the soft bar 51 of the driving being circumferentially the center of circle with the axle center of the first axle 11, and this part is protruding, thus relative for backrest railing 3 back rest 2 is outwards ejected by drive spindle 41; Otherwise, when upwards rotating back rest 2, namely adjust back rest 2 relative thereto 1 angle to diminish, a pocket is made to adjust to the process of sitting posture from lying posture, around the soft bar more than 51 of the driving being circumferentially the center of circle with the axle center of the first axle 11, thus relative for backrest railing 3 back rest 2 pulls back by drive spindle 41.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
