Detailed description of the invention
Below in conjunction with the accompanying drawings and the embodiment water bath that provides the present invention is described further.
As shown in Figure 1, a kind of adjustable for height water bath of test tube rack, including casing 1, test tube rack 2.
As shown in Figure 1, also including test tube rack lowering or hoisting gear, this test tube rack lowering or hoisting gear includes two inverted u-shaped liftings
Frame 3, two cranes are symmetrically distributed in casing both sides, and the tank wall 11 of casing both sides is positioned at the opening of crane 3, tank wall 11 and liter
The interior side frame wall 31 of fall frame is fitted, and test tube rack 2 is located between two cranes 3 and is connected with two cranes fixing.
As shown in Figure 1, lowering or hoisting gear is additionally included on the outer side frame wall 32 of crane and connects fixing spring follow block 4 and determine
Position axle 5.As shown in Figure 1, locating shaft 5 is provided with spring boss 6, and locating shaft 5 is inserted through crane by spring follow block 4 is outside
The tank wall 11 of outer its end of side frame wall 32 and casing offset, wherein spring boss 6 is positioned at spring follow block 4 side frame outer with crane
Between wall 32, the locating shaft between spring boss 6 and spring follow block 4 is provided with support spring 7.
As shown in accompanying drawing 1 and accompanying drawing 3, inside tank wall 11, it is provided with vertical cavity 15, outside tank wall, has several
The through hole 16 through with cavity.
Also including positive stop strip 14, shown in the structure of positive stop strip 14 as accompanying drawing 4, it includes spring steel plate 13, at spring steel plate
Several semi-cylindrical hills 9 it are sequentially provided with on 13.
As shown in accompanying drawing 1 and accompanying drawing 3, it is internal that spring steel plate 13 is positioned at tank wall cavity 15, and semi-cylindrical hill 9 is stretched by through hole 16
Going out, the bottom of spring steel plate 13 is fixed with tank wall 11, and the top of spring steel plate is in free state, at the spring steel plate back side with empty
It is provided with spring 17 between the cavity wall of chamber, makes spring steel plate 13 be adjacent to tank wall 11 under the effect of spring 17.
After using this to arrange, after crane 3 is applied active force up or down, the semi-circular ends of locating shaft with
Semi-cylindrical hill 9 occurs extruding to be formed when " rotation ", and locating shaft 5 is displaced outwardly, and semi-cylindrical hill 9 drives spring steel plate
13 is internal mobile to tank wall cavity 15, and both occur relative movement, and the end of locating shaft is easy to cross a semi-cylindrical hill,
After semi-cylindrical hill is crossed in the end of locating shaft, support shaft is moved to tank wall under the effect supporting spring 7, spring steel plate 13
Under the effect of natural resiliency and spring 17, semi-cylindrical hill 9 is ejected again, the end of support shaft be positioned at two semicircular protruding 9 it
Between form the effect of limitation locking.When being continuously applied active force downward or upward, locating shaft and semi-cylindrical hill produce repeatedly
Raw relative motion, the end of locating shaft can cross semi-cylindrical hill one by one easily, so that crane produces lifting effect
Really.
Owing to semi-cylindrical hill is after being squeezed, the spring steel plate 13 in cavity 15 produces inclination, semicircle from bottom to top
Shape projection is tilted into cavity, as shown in Figure 3, the diameter of through hole 16 is set greater than the diameter of semi-cylindrical hill 9,
Ensure that semi-cylindrical hill 9 passes in and out through hole 16 easily.
Further, for ensureing the crane 3 stable lifting on tank wall 11, as shown in Figure 1, in the present embodiment,
Being provided with vertical rail cavity 10 inside tank wall 11, in crane, side frame wall 31 is provided with slide rail 12, and slide rail 12 is positioned at rail cavity 10
Internal.
The most as shown in Figure 1, it is provided with heating plate 18 at casing inner bottom part, is provided with heater strip 19 in heating plate, in casing
Wall is provided with temperature sensor 20, is provided with electric control box 30 outside casing, and described heater strip 19, temperature sensor 20 are with automatically controlled
Case 30 processed electrically connects.
When carrying out water-bath operation, electric control box 30 controls heater strip 19 and obtains electric, heats the water in water bath, when
When reaching set point of temperature, temperature sensor 20 sends signal, and electric control box 30 cuts off the power supply of heater strip 19 and stops heating.
For preventing during movement, the test tube on test tube rack vibrates, and causes invisible spectro liquid to trickle down, in examination
Pipe support is provided with test tube hold down gag.As shown in Figure 2, test tube rack 2 has several test tube holes 21, test tube hold down gag by
Post 26 fixed by clamping plate 25, pressing plate 24, spring leaf 27, spring leaf and connecting shaft 23 forms.
As shown in Figure 2, the front surface at test tube rack offers the intercommunicating pore 22 being connected with test tube hole 21, connecting shaft 23
One end is fixedly connected with pressing plate 24, and the other end is fixedly connected with clamping plate 25 after intercommunicating pore 22 in test tube hole 21.
