A kind of rack
Technical field
The present invention relates to be used for the rack of constant water bath box.
Background technology
Constant water bath box of the prior art when article are carried out Temperature Treatment, directly places water bath with the container that holds article owing to be not equipped with special rack, and container bottom directly contacts the heating or the refrigeration bar of constant water bath box bottom.Can make the processed article inequality of being heated like this, cause the result inaccurate easily.Simultaneously for the little container of volume, produced vibration easily by water impact and finally cause leakage or break, and inconvenience when taking.
Summary of the invention
At the deficiency that prior art exists, the present invention aims to provide a kind of rack.This rack can be placed in one article, the effect of playing protection, isolating with its thing.
The technical solution used in the present invention is:
A kind of rack, comprise hanger and bracing frame, described hanger by parallel two fixed strips and between two parallel activity bar form shaped as frame, fixed strip is provided with strip through-hole, activity bar one end is fixedlyed connected with an end of fixed strip, the other end is connected in the through hole of fixed strip and can slides arbitrarily in the through hole of described fixed strip by screw, bracing frame is made up of the support bar of " L " type, is connected with activity bar on it.
One side near the rack inner space on the described fixed strip is arc, is adapted to the shape of bulge.
The below of described two activity bar is respectively equipped with the many support bars that are arranged side by side.
Described support bar is cylindric or lath-shaped.
This rack can be placed in one article; the effect of playing protection, isolating with its thing; particularly be used in the water bath with thermostatic control; heating or refrigeration bar at the bottom of processed article and the water bath are isolated; be heated evenly, the enlarging or reducing volume of this rack is for the little article of volume; can avoid the impact of current, the stable Temperature Treatment of carrying out.
Description of drawings
Fig. 1 is a structure chart of the present invention.
The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
Description of reference numerals is as follows:
1---fixed strip
2---activity bar
3---strip through-hole
4---screw
5---support bar
As shown in Figure 1, this rack mainly is made up of hanger and bracing frame, wherein hanger by parallel two fixed strips 1 and between two parallel activity bar 2 surround shaped as frame, fixed strip 1 is provided with strip through-hole 3, activity bar 2 one ends are fixedlyed connected with an end of fixed strip 1, the other end is connected in the through hole of fixed strip 1 by screw 4, can in the hole, slide arbitrarily, be used to regulate the size of rack inner space, bracing frame is made up of the six roots of sensation columned " L " type support bar 5, and its upper end is connected with activity bar 2, and each activity bar below has three respectively, one side near the rack inner space on the fixed strip is arc, can adapt to the shape of bulge.
During use, rack is put into water bath, hanger is hung over the water bath mouth, the container that will handle is put into the inner space of rack, according to the size slip activity bar of container, drives support bar and moves, thereby form sizeable rack inner space.
The present invention is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present invention.Though but on its shape or structure, do any variation, every identical with the present invention or akin technical scheme is all within its protection domain.
