Fig. 2 is the combination section of the utility model pipe assembly;

Fig. 3 is the three-dimensional exploded view of the utility model pipe assembly, and shows the relativeness of the angle seat of itself and infanette; With

Fig. 4 is the three-dimensional combination figure that the utility model pipe assembly is assembled in infanette and diaper platform device.

The specific embodiment

Shown in Fig. 2,3, the cap unit 8 of the utility model closed tube 7 ends comprise a V-type elastic arm 81, from one first finger 82 that V-type arm 81 1 distal process go out, from a circular cap 83 of V-type arm 81 other end horizontal expansions, from cap 83 to arm 81 extend and diameter less than a ring-like flange 84 of the diameter of cap 83, a near protuberance 85 that arm 81 and cap 83 junctions, radially extends and the inflection point 86 that is positioned at V-type arm 81 towards cap 83 periphery near and near cap 83 from one second finger 87 far away, first finger 82.This second finger 87 is laterally also omiting towards protuberance 85 oblique extensions towards arm 81.In another embodiment, second finger 87 also can only be extended towards the transverse horizontal of arm 81.

The pipe assembly 6 that the utlity model has cap unit 8 comprises a hollow tube 7 and a cap unit 8.This cap unit 8 as mentioned above; 7 of this bodys comprise the opening 71 that is positioned at the one end, longitudinal extension and a breach 72 that is communicated with opening 71 from these opening 71 places towards body 7, on body 7 cross-sectional direction with lack 72 radially relative but with open 71 and keep a bit of distances and one first groove 73 that is not communicated with and far and one second notch 74 that on body 7 is vertical, aligns with breach 72 apart from opening 71.

Cap unit 8 is assembled in body 7 and forms pipe assembly 6

The arm 81 of cap unit 8 with the direction of inflection point 86 towards hollow tube 7 inside, is inserted in the bodys 7 from the opening 71 of body 7.Wherein, the protuberance 85 first parts of cap unit 8 are placed in the breach 72 of body 7, with the effect of first and

second finger

82,87 of producing correcting cap unit 8.Then, protuberance 85 is under the guiding of breach 72, continue basal sliding (that is up slides at Fig. 2,3) toward breach 72, in the protuberance 85 of cap unit 8 is placed in the breach 72 of body 7 fully, second finger 87 of cap unit 8 from second notch 74 of body 7 give prominence to and the flanges 84 of cap unit 8 be placed in body 7 open in 71 till.Because the distance of 81 liang of ends of V-arrangement arm is greater than the internal diameter of body 7, and V-arrangement arm 81 is to be made by for example plastics elastomeric material, so V-arrangement arm 81 is compressed and is placed in the body 7, but first finger 82 can be outstanding from first groove 73 of body 7 because of the elastic restoring force of arm 81.In addition, the protuberance 85 of cap unit 8 is radially outstanding from the breach 72 of body 7 at this moment.

By above-mentioned assembling process as can be known, the protuberance 85 of cap unit 8 has accessory cover unit 8 and body 7 mutual contrapositions and the effect of assembling easily.

Pipe assembly 6 is assembled in infanette 1

Infanette 1 shown in Fig. 3,4 comprises a support 2, around support 2 and a lamellar body 3 of bottom, be individually fixed in four jiaos of seats 4 in four corners, support 2 upper ends and be inserted in a diaper platform device 5 of adjacent two jiaos of seats 4.Pipe assembly 6 of the present utility model is the part of diaper platform device 5, and extends from its lower ends downward.

Each arc angle seat 4 of infanette 1 comprises a hole 41 that is positioned at the rough mid point of arc and a groove 42 that is parallel to this hole 41 and is connected with this hole 41.

The upper end of pipe assembly 6 of the present utility model connects or is fixed in the lower end of diaper platform device 5; The lower end of pipe assembly 6 is inserted in the hole 41 of angle seat 4 with the groove 42 of its protuberance 85 or second finger, 87 alignment angle seats 4, this moment, first finger 82 of pipe assembly 6 can be subjected to the extruding of angle seat 4 and in first notch 73 of retraction pipe assembly 6, when the lower end of angle seat 4 is passed through in first finger 82, elastic restoring force by arm 81, first finger 82 is just given prominence to first groove 73 once again and is stuck in the lower surface of angle seat 4, upwards breaks away from angle seat 4 in order to prevent pipe assembly 6 (or whole diaper platform device 5).

Effect

Because cap unit 8 has flange 84, first finger 82 and second finger 87, and be sticked in opening 71, first groove 73 and second groove 74 of body 7 respectively, so by these three block chalazas, just can make cap unit 8 firmly be incorporated into body 7, even if bump or vibration or pipe assembly 6 are when being assembled in 1 jiao of seat 4 of infanette or pipe assembly 6 friction that produces when 1 jiao of seat 4 of infanette is separated, cap unit 8 does not have the anxiety worry of dropping from body 7.

Moreover because cap unit 8 has protuberance 85, and cap unit 8 is assembled in body 7 and when forming pipe assembly 6, this protuberance 85 still radially emergence outside body 7.Therefore when pipe assembly 6 will be assembled in the angle seat 4 of infanette 1, must could insert in the hole 41 of angle seat 4 with the groove 42 of the protuberance 85 alignment angle seats 4 of pipe assembly 6.So the protuberance 85 of pipe assembly 6 has the fool proof function, the diaper platform device 5 that pipe assembly 6 upper ends are connected must be positioned at the top of infanette 1 inboard, can not be positioned at the top in infanette 1 outside.

But the above, it only is preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this, be that every simple equivalent of being done according to the utility model claim and utility model description changes and modifies, all should still belong in the scope that the utility model patent contains.
