Abstract

The technical scheme of the utility model provides a lockable joint mechanism for chassis of baby encircling bed, comprising a central supporting seat, a lockable supporting tube, a sliding pin, a rotating cam, a control component, a central combination seat, a torsion spring, a pressure spring, a pivot, a screw and a nut, which is characterized in that the lockable supporting tube is movably pressed into the position corresponding to a central supporting seat by the pivot; the torsion spring and the rotating cam are built in the middle of the central combination seat with the torsion spring and the rotating cam; the upper end of the rotating cam is rotationally connected with the control component by the screw and the nut to form a unlocking device, and then inserted and rotationally built in the central supporting seat; the pressure spring and the sliding pin are sleeved into the port of the lockable supporting tube; one head of the sliding pin is locked under the central combination seat under the effect of the pressure spring. The chassis of the chassis of the whole baby encircling bed is locked, which cannot be unlocked by single folding upwards. As the control component on the unlock device is rotated clockwise so that the rotating cam is driven to push the sliding pin out of the unlock device for unlocking and then the control component is pulled upwards in series twice, thus improving the security.

Description

Baby's bed chassis lockable articulation mechanism

Technical field

The utility model relates to a kind of folding joint mechanism, particularly a kind of baby's bed chassis lockable articulation structure that is used for.

Background technology

At present, known baby's bed must launch when using, and volume is beneficial to children more greatly and uses, the time spent does not fold it, and volume is urinated in collection very much, and need only upwards lift the folding band during folding can directly fold, because the folding action is too simple, this brings hidden danger for naughty children.

Summary of the invention

The purpose of this utility model is: provide a kind of baby's of preventing bed to cause baby's bed chassis lockable articulation structure of dangerous accident because of misoperation.

The technical solution of the utility model is: baby's bed chassis lockable articulation structure, comprise center spike seat, can lock the spike pipe, sliding pin, rotating cam, control part, the center connecting support, torsion spring, stage clip, the spike pipe, the side stay pipe, pivot, cover plate, screw, nut and self-tapping screw are in interior structure, it is characterized in that: can lock the spike pipe, the spike pipe, the side stay pipe is by on the active position that is pressed into center spike seat correspondence of pivot, embed torsion spring and rotating cam in the middle of the connecting support of center, screw, nut is rotatably connected the rotating cam upper end and controls part, thereby the tripper of forming, rotate again in the spike seat of embedding center by after inserting, make the cooperation that crosses one another of two groups of boss.Stage clip, sliding pin be inserted in can lock in the spike pipe port, be stuck under the connecting support of center one of stage clip effect lower slide pin, whole baby's bed chassis is locked, and single upwards folding action can not be unlocked opens.

The beneficial effects of the utility model are: because by the part of controlling on the tripper that turns clockwise, the interlock rotating cam ejects the tripper release with sliding pin, then upwards lift and control the so coherent secondary action of part, be obedient to folding direction and improved security.

The specific embodiment:

Shown in Fig. 1-5: the utility model comprises: the sliding pin 4 that body 1, tripper 2, all right one way or the other lock spike pipe 3 are corresponding with two, and it is characterized in that: this body 1 top is provided with tripper 2, and periphery is established the spike the locked pipe 3 of two correspondences; Releasing device 2 is by center connecting support 7, control part 6, rotating cam 5, torsion spring 8, screw 14, nut 15 constitutes, rotating cam 5 tops are closed seat 7 bottom centre's borehole jacks from centre junction and are gone into, screw 14 is worn the footpath and is controlled part 6, rotating cam 5 tops, cooperate with nut 15, can swing when controlling part 6 mat screws 14 and rotating cam 5 tops and be the axle center operation and rotate on the center connecting support 7, center connecting support 7 is provided with two circular arc boss 711 in tripper 2 assemblies, by inserting the circular arc boss 173 that is provided with two sides in spike seat 17 chambeies, center, after again rotation embed, two groups of boss are crossed one another cooperate to form body 1.

All right one way or the other lock spike pipe 3 is provided with perforation 31, pivot 12 places wherein, all right one way or the other lock spike pipe 3 its inside are embedded with stage clip 9, stage clip 9 one ends are established by pivot 12 folders, the other end embeds in sliding pin 4 chambeies and is kept out, open slot 411 is arranged on the sliding pin 4, and placed and be combined in by pivot 12 and can lock spike pipe 3 ends, there are an end face 412 and an arcwall face 413 in sliding pin 4 outer ends.Center spike seat 17 peripheral sides are provided with six bottoms and are the front and back symmetry shape for three couples of tube seat 17A, 17B, the 17C that opens shape, the tube seat of three correspondences, can lock spike pipe 3 to link respectively, spike pipe 10, side stay pipe 11,

tube seat

17A, 17B, 17C back two sides laterally are provided with V-shaped groove 171, V-shaped groove is provided with inclined-plane boss 172 about 171 tops, and place 12 pivots and be pressed into V-shaped groove 171 in locking on spike pipe 3 and spike pipe 10 and the side stay pipe 11 perforation 31, and with 172 pinnings of inclined-plane boss, forming and using 12 pivots is that the axle center is the swing shape.Wherein can lock spike pipe 3 inside has stage clip 9, sliding pin 4, and stage clip 9 one ends are established by pivot 12 folders; Stage clip 9 other ends embed in sliding pin 4 chambeies, sliding pin 4 is not being had under the situation of external force, sliding pin 4 is overhanging shape, when opening play yard, blocking surface 712 in the groove on the sliding pin 4 overhanging arcwall face 413 acceptor center connecting supports 7 and compression backward, in the time can locking spike pipe 3 for the horizontal shape, sliding pin 4 breaks away from blocking surfaces 712, under the rebound effect of stage clip 9, insert connecting support 7 bottoms, center and lock.
