The slope solid structure is arranged in the cylinder device, the transmission mechanism is arranged under the slope solid structure, a slope solid can be in reciprocating type vertical motion along with rotation motion of the transmission mechanism, and the control device is connected with the transmission mechanism and used for controlling actions of the transmission mechanism. The small article testing instrument achieves the fact that experimenters can take out tested parts in the testing cylinder through improvement on traditional small article testing instruments.
Description
Technical field
The invention belongs to mechanical field, relate to a kind of small articles tester that utilizes physical construction to realize taking out the parts to be tested in the test barrel.
Background technology
The small articles tester is the throat that is used for simulating children below 3 years old, and whether the evaluation toy has by child's mistake in use and after rationally abusing gulps down object and the device of asphyxiant danger.
Traditional small articles tester is exactly a cylinder-shaped device of imitation children's below 3 years old throat; When experiment; Under the situation of no ambient pressure; Lean on own wt can hold fully into the test cup with any one angle the test specimens of dismounting parts or releasing part on the toy of 3 years old following playing by children, this part is judged to be small articles, otherwise does not then belong to small articles as being regarded as small articles through these parts.
The inner slope entity structure of traditional small articles tester is immobile, and general parts to be tested are smaller, is difficult to take out.So when accomplishing test, lab assistant will be picked up the small articles tester, and parts to be tested are poured out.The small articles tester is a stainless steel device, and its volume is very little.On the one hand, the very little very difficult taking-up of the parts of mistake to be tested, the not enough science of the method for pouring out; Also increased the labor load of lab assistant on the other hand.
The defective that existing small articles tester exists is:
1, the slope entity structure and the cylinder unit of the test barrel of existing small articles tester link together, can't be movable, and therefore inconvenience is taken out unit under test.
2, existing small articles tester does not possess automatic function.
Summary of the invention
The objective of the invention is to the prior art defective; Provide a kind of small articles tester that can move freely the inner slope entity structure of cylinder unit to come effectively to overcome above-mentioned deficiency, thereby realize a kind of small articles tester that after experiment is accomplished, can easily take out parts to be tested.
The present invention realizes in the following manner: a kind of small articles tester comprises cylinder unit, slope entity structure, gear train, control device; Said slope entity structure is inner at said cylinder unit; Said gear train is positioned at said slope entity structure below; And said slope entity moves up and down along with the motion of said gear train is reciprocating type; It is outside that said control device is positioned at said cylinder unit, and said control device is connected with said gear train, is used for controlling the action of gear train.
Said cylinder unit inwall closely pastes with the slope entity structure mutually; Said gear train is a cam drive; The power source of said cam drive is 90 degree rotary cylinders; Said gear train is a slider-crank mechanism; The power source of said slider-crank mechanism is a motor.
The invention has the advantages that:
1, can realize moving up and down of slope entity structure, alleviate experimenter's labor load;
2, the present invention is simple to operate, and is practical;

Wherein:
11 is cylinder unit, and 12 is 90 degree rotary cylinders, and 13 is the slope entity structure, and 14 is supporting base, and 15 is cam drive, and 16 is parts to be tested; 20 is parts to be tested, and 21 is cylinder unit, and 22 is the slope entity structure, and 23 is bearing seat, and 24 is motor, and 25 is driving-belt, and 26 is power wheel, and 27 is bent axle, and 28 is connecting rod, and 29 is base;
Embodiment
The small articles tester of embodiments of the invention 1 for adopting the cam mechanism transmission to realize, the structural drawing under its trystate is as shown in Figure 1.Comprise cylinder unit 11,90 degree rotary cylinders 12, slope entity structure 13, supporting base 14, cam drive 15 and parts to be tested 16.Slope entity structure 13 is positioned at cylinder unit 11 inside, and cam drive 15 is positioned at the bottom of cylinder unit 11, the below of slope entity structure 13.The external diameter of slope entity structure 13 is close to the internal diameter of cylinder unit 11, and the supporting base 14 of cylinder unit 11 and cam drive structure 15 all is fixed on the base.The cam of cam drive 15 is different with respect to the radius of center of rotation, moves up and down so promote slope entity structure 13 when cam drive 15 turns to different angles.The power source of cam drive 15 is 90 degree rotary cylinders 12.90 degree rotary cylinders 12 have only two states; 0 degree and 90 degree; Guaranteed so all to be in a fixing position when slope entity structure 13 is at two states when test, and can not fall into cylinder unit inside and produce mobile because of parts to be tested when testing.Embodiment 1 is when the state in when test, and the anglec of rotation of 90 degree rotary cylinders 12 is 0 degree.Because 90 not rotations of degree rotary cylinder 12 so the cam of cam drive 15 does not rotate, are in the lateral attitude.Thereby make the slope entity structure 13 in the cylinder unit 11 be in minimum point.This moment, the inner structure state of small articles tester was identical with the inner structure state of traditional small articles tester.
State when embodiment 1 takes out parts to be tested is as shown in Figure 2.90 degree rotary cylinders, 12 motions this moment; Make that the cam rotation angle of cam rotating mechanism 15 is 90 degree; This moment, cam peaked at vertical direction; Thereby make slope entity structure 13 in cylinder unit 11, be at the highest notch, parts to be tested 16 are released cylinder units 11, or reach lab assistant and stretch out one's hand the convenient location that to touch.Fig. 3 is the overall appearance figure of embodiment 1, comprises cylinder unit 11 and slope entity structure 13.
The embodiment 2 small articles tester for adopting slider-crank mechanism to realize, its structure is as shown in Figure 4: parts to be tested 20, cylinder unit 21, slope entity structure 22, bearing seat 23, motor 24, driving-belt 25, power wheel 26, bent axle 27, connecting rod 28, base 29.Wherein, slope entity structure 22 is in cylinder unit 21 inside, and slope entity structure 22 links to each other with bearing seat 23, and bearing seat 23 links to each other with bent axle 27 through connecting rod 28, and bent axle 27 links to each other with power wheel 26, and power wheel 26 links to each other with motor 24 through driving-belt 26.Slope entity structure 22, bearing seat 23, bent axle 27 and connecting rod 28 have been formed slider-crank mechanism.Motor 24, cylinder unit 21 are fixed on the base 29 with slider-crank mechanism.Motor 24 drives power wheel 26 through driving-belt 25 and rotates, and power wheel 26 drives bent axle 27 and rotates, thereby makes slider-crank mechanism produce motion.Slider-crank mechanism changes into rotatablely moving of bent axle 27 oscillating rectilinear motion of slope entity structure 22.This figure figure under experimental state, slider-crank mechanism is positioned at minimum point, and certain position of cylinder unit 21 inside of slope entity structure 22 this moment when experiment makes the small articles tester be in the state when testing.
When test is accomplished; Motor 24 drives travelling belt 25 and rotates; Thereby make the crank 27 in the slider-crank mechanism turn to peak, make slope entity structure 22 rise, thereby make parts 20 to be tested arrive the open upper end place of cylinder unit 21; As shown in Figure 5, thus make lab assistant can easily take out parts 20 to be tested.Can be in the actual experiment through the action of motor controller control motor.Fig. 6 is the appearance assumption diagram of tester, comprises cylinder unit 21, slope entity structure 22 and base 29.
The present invention has carried out special description to disclosed a kind of small articles tester, but above-mentioned be schematically not to be determinate, those skilled in the art belong to the scope of the present invention's protection in the modification that does not depart from the scope of the invention to be done.
