Further, described guiding mechanism comprises a cylinder vertically arranged, cylinder closed at both ends arranges and is fixed on door leaf body lower part, described helical spring is arranged in cylinder matchingly, helical spring lower end abuts the lower slide plate having a horizontally disposed circle, lower slide plate external diameter and cylinder internal diameter mate and can slide up and down to be arranged in cylinder, have the lower support bar arranged straight down in the middle part of lower slide plate soffit, lower support bar lower end extends downwardly through the mating holes in the middle part of cylinder bottom slidably and is fixedly connected with described roller.
Like this, guiding mechanism has the simple and advantage such as reliable and stable that leads of structure, and spring is placed in cylinder simultaneously, effective to spring protection, avoids spring corrosion and affects use.
As further optimization, described cylinder is fixed on door leaf body by a stator, the overall elongated sheet of described stator, its length direction medium position arches upward the deep-slotted chip breaker that is formed with one and cylinder cylindrical coupling for banding stationary cylinder body, and the position that stator is positioned at deep-slotted chip breaker two ends is provided with screw hole and for being fixed on door leaf body by screw.
Like this, the fixed installation of cylinder is facilitated.
Further, described cylinder external surface both sides are vertically arranged at intervals with multipair projection, and stator is spacing between adjacent protrusion by clamping.Like this, projection can be leaned on to carry out the spacing of above-below direction to stator, ensure fixing reliability is installed.
Further, also comprise height adjustment mechanism, described height adjustment mechanism comprises the upper slide plate be positioned at above cylinder inside spin spring, upper slide plate external diameter and cylinder internal diameter mate and can slide up and down to be arranged in cylinder, upper slide plate upper surface middle part is provided with a stud upwards extended, and described stud is by the screwed hole of threaded engagement in the middle part of cylinder upper end cover arranges one and regulate handle after extending screwed hole upper end.
Handle can be regulated, the height and position of slide plate in adjustment by rotating like this, and then adjust helical spring compression stroke, and then realize the elastic force of elastic telescopic device and the adjustment of retractable height, to adapt to different surface conditions better.
In sum, it is simple that the utility model has structure, with low cost, and guiding is reliable, long service life, and conveniently regulate the advantages such as elastic force.
