Description
Technical field
The present invention relates to a kind of child bed, particularly to the child bed of a kind of liftable guardrail, apply also for kindergarten, household children use.
Background technology
Market existing liftable guardrail structure is a kind of to be made up of the lockhole on the locking bar on guardrail, guardrail, slideway and slideway. The use principle of its guard bar lifting process is: both hands mention guardrail and the lockhole that compares on slideway makes the locking bar on guardrail enter the lockhole on slideway to reach the guardrail locking purpose in a certain position. In use there is certain deficiency in this liftable guardrail latch-up structure, such as: common guardrail is heavier, uphill process needs by manpower to overcome all gravity of guardrail self, it is easy to consume too much muscle power, if careless landing easily causes danger in lifting process. And locking bar there be difficulties involved when with compareing of lockhole, in use cause unnecessary trouble. Another kind is the guard bar lifting structure with hydraulic means, this guardrail is driven guardrail to rise when rising by hydraulic means, save manpower, but need manpower to overcome the active force of hydraulic means that guardrail is pressed when guardrail declines, and this structure for female user it is possible that because when dynamics does not press guardrail.
Summary of the invention
In order to overcome the problems of existing liftable guardrail, the present invention provides the child bed of a kind of liftable guardrail, and this structure can not only effectively reduce the gravity of guardrail self, becomes lighter in running, and its locking process is also lighter.
Technical scheme:
The present invention is for achieving the above object, be the technical scheme is that the child bed of a kind of liftable guardrail, including guardrail, side rail, the bedstead of castor is installed, it is characterised in that: also include trim, column slide rail, power-assisted bascule, guardrail lock, guider;
Described power-assisted bascule includes wind spring lid I, wind spring lid II, wind spring, wind spring guide pad, upside is stifled, guardrail hanging scroll, described wind spring lid I is together with wind spring lid II spiral-lock, described wind spring is arranged in the open slot of wind spring lid I and wind spring lid II, stretch out the wind spring one end outside open slot and be fixed in the groove of wind spring guide pad, one end of described guardrail hanging scroll is installed on one end of wind spring, it is stifled that the other end of guardrail hanging scroll installs upside, in the stifled long transverse tube being arranged on side, guardrail upper end in upside, the structure of the power-assisted bascule that described guardrail opposite side is provided with is with the mounting structure of above-mentioned side,
