The locking mechanism for locking upper loop bar is provided between pipe and setting of casing.
The locking mechanism includes the threaded hole being arranged on setting of casing tube wall and the jackscrew that is threadedly engaged with threaded hole.
The locking mechanism include the spring catch being arranged on upper set club shaft and be arranged on setting of casing tube wall along upper
The height adjusting holes with spring catch cooperation that lower direction is arranged in "-" type.
The upper surface of the pedestal is in enclosing the collecting tank equipped with indent in support rod.
The notch of the collecting tank is in flaring structure.
Be spliced the beneficial effects of the utility model are: setting plate by preceding placement plate and rear placement plate, preceding placement plate, after put
It sets the opposite side of plate and is respectively equipped with preceding semicircle orifice and later half circular hole through plate thickness, formed after preceding semicircle and the splicing of later half circular hole
For the putting hole of holding test tubes, it is equipped between preceding placement plate and rear placement plate for adjusting between preceding placement plate and rear placement plate
The radial direction of putting hole is adjusted by the aperture adjusted between the preceding placement plate of adjustable diameter and screw adjusting and rear placement plate for the adjusting bolt of aperture
Size, to meet the test tube needs of different tube diameters,
Compared with the rack for test tube in technology, the rack for test tube versatility of the utility model is good.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the embodiment 1 of rack for test tube of the utility model；
Fig. 2 is the top view of placement plate in Fig. 1；
Fig. 3 is a kind of structural schematic diagram of the embodiment 2 of rack for test tube of the utility model.
Specific embodiment
The embodiment of utility model is described further with reference to the accompanying drawing.
A kind of embodiment 1 of rack for test tube of the utility model, as shown in Figure 1 to Figure 2, shown rack for test tube include length along left and right
The pedestal 1 that direction extends, the left and right ends of pedestal 1 are equipped with the support rod 2 that length vertically extends, two support rods 2 it is upper
End is fixed with placement plate 3, and placement plate 3 is spliced by preceding placement plate 31 and rear placement plate 32, the preceding placement plate 31, rear placement
The opposite side of plate 32 is respectively equipped with preceding semicircle orifice 311 and later half circular hole 321 through plate thickness, preceding semicircle orifice 311 and rear semicircle
Hole 321 forms the putting hole 33 for being used for holding test tubes after splicing, putting hole 33 is in be equipped with to arrange in "-" type in the lateral direction,
