A kind of test tube clamping device
Technical field
The present invention relates to a kind of test tube clamping devices.
Background technique
In strain experiment, sterile working is generally required, and there are many tested number, while may needed during the test
Individual test tubes are adjusted, the mode of operation that the prior art takes this, often in an aseptic environment, manually with hand pair
Single test tube is picked and placed, in this way, on the one hand enter gnotobasis for adjustment once in a while to operator and carry out complexity
Sterilization operate pole waste of resource, it is also extremely inconvenient, on the other hand due to pushing limited, also cause putting for test tube can not
Accomplish the maximization of space utilization.Also there is the mechanical device for picking and placing test tube in the prior art, but that generally takes full-automation
Operation, equipment supplier do not provide individual test tube fetching device generally, and the selling at exorbitant prices of a complete set of equipment, for middle-size and small-size enterprise
Industry is difficult to undertake really.It is various above to cause medium-sized and small enterprises' cost in the experiment of batch strain excessively high, and dangerous, by
This also causes medium-sized and small enterprises to be difficult to efficiently use having talent of high caliber.
As the Chinese invention patent of Patent No. CN201120576509.2 discloses a kind of clamping of test tube clamping device
Body completes the clipping operation to single test tube using supporter, fixture rotor and sheet rubber, it is clear that the actual product of the technology is not
It may be provided separately, and complete equipment higher cost, medium-sized and small enterprises necessarily cause in the case where undertaking such high expense
Cost is excessively high, thus necessarily bears elevated pressures in fund aspect, to improve the operations risks of enterprise.
Summary of the invention
In order to solve the above technical problems, the test tube clamping device passes through pure the present invention provides a kind of test tube clamping device
Mode mechanical, at low cost, easy to maintain realizes the non-manual operations that gnotobasis takes individually pipe, and reliable and stable, can have
Effect reduces experiment risk and solves sterilization resource.
The present invention is achieved by the following technical programs.
A kind of test tube clamping device provided by the invention, including holding ring, puller strap, movable block, strut;The holding ring
Arc semi-ring for angle less than 150 °, quantity are two, and two holding ring levels are oppositely arranged;The movable block is arranged two
Among the end of a holding ring one side, and connected with the proximal end of two holding rings;The strut is vertically arranged, and movable block is moveable
It is fixed on strut bottom, the moveable direction of movable block is perpendicular to strut radial direction;The puller strap is fixed on holding ring distal end,
And it is arranged along holding ring inside and movable block towards strut side.
Movable block position is corresponded on the strut is equipped with the control knob can lock, push away, drawing movable block.
The movable block is the cambered surface of horizontal direction with respect to strut distal end side.
The position that puller strap setting is corresponded on the movable block is equipped with sliding slot.
The puller strap on each holding ring except distal end is fixed outer, other also at least one slidably fixed point.
The beneficial effects of the present invention are:It is individual that gnotobasis is realized by mode purely mechanic, at low cost, easy to maintain
The non-manual operations of pipe being taken, and reliable and stable, experiment risk can be effectively reduced and solves sterilization resource, structure is simple,
Maintenance is easy, and provides reliable guarantee for the experiment of medium-sized and small enterprises batch strain.

Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
A kind of test tube clamping device as shown in Figure 1 to Figure 3, including holding ring 1, puller strap 2, movable block 3, strut 4;Institute
Stating holding ring 1 is arc semi-ring of the angle less than 150 °, and quantity is two, and two 1 levels of holding ring are oppositely arranged;The movement
Block 3 is arranged among two 1 one side ends of holding ring, and connects with the proximal end of two holding rings 1;The strut 4 is vertically arranged,
Movable block 3 is movably fixed on 4 bottom of strut, and the moveable direction of movable block 3 is radial perpendicular to strut 4;The tension
Band 2 is fixed on 1 distal end of holding ring, and is arranged along 1 inside of holding ring and movable block 3 towards 4 side of strut.
It only needs to set 4 top of strut in the top cross bar of laboratory when use, by 1 place planar alignment of holding ring
Test tube to be taken then makes strut 4 slide into test tube position with relevant device, and test tube is made to push movable block 3 close to strut 4, from
And puller strap 2 is pulled to clamp holding ring 1, continuing thereafter with translation can clamp test tube to be taken to predetermined position, complete individual
Take the non-manual operations of pipe.
3 position of movable block is corresponded on the strut 4 is equipped with the control knob 41 can lock, push away, drawing movable block 3.It is set using this
It sets primarily to avoiding test tube clamp next leads to the feelings that holding ring 1 unclamps, test tube is fallen down because movable block 3 lacks fixed
Condition, therefore when movable block 3 pushes control knob 41 to arrive certain position, control knob 41 is automatic or locks movable block under remote control
3.Further, control knob 41 can also be controlled to push movable block 3, become the non-manual operations for putting down test tube
It may.Further, control knob 41 may also be configured to actively pull movable block 3, make extremely slightly to push even not in test tube
It realizes and clamps in the case where pushing movable block 3.
In order to avoid test tube single-point stress leads to sliding or other abnormal conditions, therefore test tube forced area should be increased,
The opposite 4 distal end side of strut of the movable block 3 is the cambered surface 31 of horizontal direction.
It fails in order to avoid the abnormal sliding of puller strap 2 causes to be detached from, therefore corresponds to the setting of puller strap 2 on the movable block 3
Position be equipped with sliding slot 32.
Further, in order to guarantee the tension effect of puller strap 2, the puller strap 2 is on each holding ring 1 except distal end is solid
Fixed outer, in addition there are also at least one slidably fixed points.
