Description

A kind of bed body folding linkage solution lock control mechanism

[technical field]

The present invention relates to a kind of bed body folding linkage solution lock control mechanisms.

[background technique]

Child play bed is mainly made of bed body and cloth, and cloth surrounds the safe space played inside for child, It can prevent from child from climbing out of to fall.The bed body of child play bed currently on the market be usually it is fixed, also have and be partially It is composed of the foldable structure that four columns and guardrail form, but these bed body fold mechanisms are typically necessary when folding Step by step unlock the clamp device of different location, then folded, operating procedure is more, and more people is needed to operate or a people Need to convert the clamp device that different orientation unlock corresponding position, poor operation convenience.Studying one kind for cooperation can be single Hand, which operates and can be realized a step, folds bed body the bed body folding gathering mechanism collapsed, and bed body can be driven by needing to study one kind Clamp device when expansion solves lockwork together.

The present invention is namely based on what such case was made.

[summary of the invention]

The purpose of the present invention is to overcome the shortcomings of the prior art and to provide a kind of simple bed body folding linkage solution lock controls of structure Mechanism processed, which drive control bar can rotate together, thus tight when bed body being unfolded under the action of control-rod It is fixedly mounted with to set and unlock together, collapsed to fold.

The present invention is achieved by the following technical solutions:

A kind of bed body folding linkage solution lock control mechanism, it is characterised in that: including bottom case 41, be hinged on the bottom case 41 The control-rod 5 of multiple tightening states that bed body expansion can be released in rotation, interior be equipped with of bottom case 41 can relatively thereon The linkage seat 431 of lower slider, the control-rod 5 stretch between one end in bottom case 41 and linkage seat 431 be equipped with both ends respectively with Control-rod 5 and the hinged connecting rod 432 of linkage seat 431 slidably connect cover 42,42 He of cover in the linkage seat 431 The stroke restricting means that limitation cover 42 slides up and down stroke with respect to linkage seat 431, the cover 42 are equipped between linkage seat 431 Being equipped with can pull what cover 42 moved upwards to draw high device 40 in pull-up, and the bottom case 41 is equipped with axis hole 411, described 42 bottom of cover is fixed with fixing axle 44, and the locking piece 45 that can pass through axis hole 411, the locking are connected in the fixing axle 44 Part 45, which is equipped in bed body unfolded state, to be stretched out in 411 bottom outer wall of axis hole to limit the voluntarily upward sliding of cover 42 Lock 451, locking piece 45 and lock can be driven when drawing high fixing axle 44 by being equipped between the fixing axle 44 and locking piece 45 The rotation drive devices of 451 rotations are located at 411 side of axis hole on the bottom case 41 and are equipped with the bonnet lock holes that can pass through for lock 451 412, device 40 is drawn high described in pulling, and cover 42 and fixing axle 44 are pulled upwardly, under the action of rotation drive device, locking 451 rotation of part 45 and lock, when lock 451 turns to the position of bonnet lock hole 412, lock 451 is pulled up into bonnet lock hole 412 To be detached from 411 bottom outer wall of axis hole, disengages and fasten, continue to draw high cover 42, when reaching the range of stroke restricting means, Linkage seat 431 is pulled to move upwards by cover 42, push lever 5 is rotated up under the effect of connecting rod 432.

A kind of bed body folding linkage solution lock control mechanism as described above, it is characterised in that: the locking piece 45 is to be arranged Axle sleeve in 44 outside of fixing axle, the rotation drive device include being radially fixed in fixing axle 44 and protruding in fixing axle The guiding axis 441 in 44 outsides, the locking piece 45, which is equipped with, slides the arc chute 452 matched with guiding axis 441, described to lead Locking piece 45 is driven to rotate when moving up and down in arc chute 452 to axis 441.

A kind of bed body folding linkage solution lock control mechanism as described above, it is characterised in that: the fixing axle 44 and locking The outer sheath of part 45 is equipped with sleeve 46, and the sleeve 46 is fixed in fixing axle 44, between the fixing axle 44 and locking piece 45 Equipped with third spring 47.

A kind of bed body folding linkage solution lock control mechanism as described above, it is characterised in that: the stroke restricting means packet The multiple sliding bars 4311 being fixed in linkage seat 431 are included, the cover 42, which is equipped with, to be inserted into and for sliding for sliding bar 4311 The sliding sleeve 421 that bar 4311 slides up and down in it, being fixed on the sliding bar 4311 can prevent sliding bar 4311 from cunning The piston piece 4312 that 421 bottoms of dynamic set skid off.

A kind of bed body folding linkage solution lock control mechanism as described above, it is characterised in that: the device 40 that draws high includes It is fixed on the handle fixing piece 401 at 42 top of cover, is rotatably connected to handle 402, the handle on the handle fixing piece 401 402 are equipped with drawstring 403.

Compared with prior art, the present invention has the following advantages:

1, when the present invention draws high device described in the pulling, cover and fixing axle can be pulled upwardly, in rotation drive device Under the action of, locking piece and lock rotation, lock turn to the position of bonnet lock hole when, lock be pulled up into bonnet lock hole to It is detached from axis hole bottom outer wall, disengages and fastens, continue to draw high cover, when reaching the range of stroke restricting means, pass through cover Linkage seat is pulled to move upwards, linkage seat pushes multiple connecting rods simultaneously, and each connecting rod pushes corresponding control-rod, so that control is more A control-rod moves together, then multiple clamp devices (such as shield in specific embodiment when by control-rod control bed body expansion Column clamp device and balustrade fastening arrangement) it unlocks together, realize that bed body folds the linkage of unlocking collapsed, while part being avoided to fasten Device locking and part clamp device the case where unlocking.

2, the lock in the present invention can be fastened in axis hole bottom outer wall to prevent cover voluntarily upward sliding, can Prevent linkage seat voluntarily upper sliding drive control bar rotation, then in bed body inclination, topple over or when vibrating state, bed body can be prevented On clamp device voluntarily unlock, use safety and stability.

3, present invention rotation driving is made of guiding axis and arc-shaped slide rail, when guiding axis moves upwards in arc-shaped slide rail, Locking piece and lock rotation unlock, when guiding axis moves downward in arc-shaped slide rail, locking piece and lock rotation locking, structure letter It is single, and the unlocking motion fusion latched is drawing high during above mentioning of device, so as to above mention can a step complete unlock and fold, Simplify operation.

4, third spring is equipped between fixing axle of the present invention and locking piece, third spring is used for fixing axle and locking piece is past Both ends press, when drawing high device described in the pull-up, so that user is easier to pull fixing axle driving lock rotation unlock.

5, stroke restricting means of the present invention are made of sliding bar, sliding sleeve and piston piece, when cover is sliding with respect in linkage seat When, in maximum stroke, piston piece is against on sliding sleeve, so that linkage seat be pulled to move together, allows to first pull cover And guiding axis, rotating latch unlock, then linkage seat is pulled to move, and the driving of control-rod is carried out, it can by above mentioning This move It is simple to operate to complete above-mentioned two process.

6, the configuration of the present invention is simple, rational and compact are readily produced manufacture.
