Description
Technical field
The present invention relates to a kind of play yard for entertainment for children, particularly relate to the guard bar structure of play yard.
Background technology
At present, child play bed has inflation or folding, the recreational bed insufficient strength of inflation, rocking dangerous, folding structure is generally more complicated, troublesome poeration, realize child play bed fold easily and launch, it is necessary to the foldable structure of a kind of novelty is applied to child play bed.
For this, technical staff has done a lot of effort, such as the Chinese utility model patent " a kind of child entertainment bed folding crossbeam joint " (Authorization Notice No. is CN203354119U) that the patent No. is ZL201320434899.9, this patent includes hinged with the first Half Beam and the second Half Beam respectively crossbeam connector of the first Half Beam and the second Half Beam and two ends, crossbeam connector is fixed with step deck, step deck both sides are provided with kayser step, first Half Beam and the second Half Beam are respectively articulated with and can block the card lock dog being locked on described kayser step, card lock dog is connected with crossbeam stay cord, top pressure torsion spring it is respectively equipped with between card lock dog and the first described Half Beam and the second Half Beam.This patent can by the child entertainment bed folding crossbeam joint of folding stay cord Foldable.Although operation brings great convenience above, but foldable structure is complicated, and parts are many, and production cost is high；Foldable structure stability is relatively low simultaneously, and fixing fastness is inadequate, there is potential safety hazard.
As improvement, the Chinese invention patent application that the applicant discloses one " fold mechanism of play yard guard bar " (publication number is CN104545130A) is open, sees that application number is 201410857407.6.Fast folding and expansion is realized in this application by the quadric chain of guard bar, activity template, swing intermediate plate and swing sheet.Guard bar locks after launching and unblock does not interfere with each other, and flexible operation is laborsaving.But folding mechanism structure or complex, parts are many, require higher to Product Precision in manufacture process, flexible not enough because of the resistance of spring when unlocking again.
On this basis, the Chinese invention patent application that the applicant discloses again one " the folding device of play yard guard bar " (publication number: CN104799624A) is open, see that application number is 201510243167.5, this application resets and locking adopts magnet arrangement, Magnet can adsorb activity template and play quickening reset speed, reduce the effect firmly that resets, and after guard bar is fully deployed, Magnet can continue to adsorb activity template, prevent activity template from again moving, play locking guard bar and improve the effect of folding device stability.Being swift in motion during unblock, as long as departing from Magnet when namely unlocking just there is no resistance, so can unlock moment, although stability and fastness are greatly improved, but existing following not enough:
First, when folding device is mentioned, if the frictional force that the frictional force of stay cord and stay cord set inwall is too big or quadric chain rotates is too big, the suction of Magnet is not enough to overcome its frictional force, activity template is not on the position set, activity template cannot offset with Magnet and hold and positioned, ultimately result in and be difficult to lock, folding device is made to be in false lock state, ultimately result in play yard during normal use folding device accidental unlocking, left guard bar and right guard bar present V-shaped groove, and more seriously this V-shaped groove easily blocks baby child's neck death by suffocation.
Second, because of the first rotating shaft and the first lever shaft close together, during unblock, cause that the first swing sheet drives the power of the first activity template more weak, for this, the first rotating shaft and the first lever shaft distance are zoomed out layout, to increase the arm of force, but like this stroke up and down of motion bar will certainly being made to increase, thus needing housing is made widening treatment, causing bulky, therefore, unblock driving force should be increased, do not increase small product size again, can not effectively be solved always.
3rd, existing two support chips are independent design, and are each located at the side of housing, and housing is also that front and back two panels is combined composition, there is intensity not high, and load is restricted, and stability and reliability have much room for improvement.
Summary of the invention
First to be solved by this invention technical problem is that and provide a kind of play yard guard bar foldable structure being avoided that false lock for the above-mentioned state of the art.
Second play yard guard bar foldable structure that technical problem is that activity template stress is enough when providing a kind of compact conformation and unblock for the above-mentioned state of the art to be solved by this invention.
To be solved by this invention 3rd technical problem is that intensity is big, stability and play yard guard bar foldable structure of good reliability.
