Referring to fig. 1 to 7, a microorganism detecting device comprises a base 1 and a vertical column 2 which is arranged at the rear part of the top surface of the base 1 and is vertically used for installing a detecting mechanism (the detecting mechanism is a detecting probe and the like which is a necessary component on the existing biological detecting device, when a sample is placed on the base 1, the probe on the detecting mechanism rotates to be close to the sample and detects the sample, the prior art is not repeated, the invention only adds functions to the base 1 of the detecting device), a connecting hole 16 for butting the detecting mechanism of the prior art is formed downwards from the top end of the vertical column 2, a fixing hole 17 for installing the detecting device on a workbench is formed on the base 1, a channel 3 corresponding to the right front side of the vertical column 2 is formed in the middle part of the top surface of the base 1, a positioning groove 4 which is communicated with the channel 3 and is in a semicircular structure is formed backwards from the front end of the channel 3, two symmetrical slide ways 5 are formed on two sides of the channel 3, two spring rods 6 which extend towards the channel 3 are respectively arranged in the direction, a positioning plate 7 which can move towards the channel 3 direction is downwards, two positioning plates 7 which are arranged towards the two positioning grooves 8 are symmetrically arranged, and two positioning plates 7 are positioned towards one end 8 of the positioning plate; when the two positioning plates 7 move oppositely to enable the two positioning parts 8 to move to the front sides of the positioning grooves 4 correspondingly, a circular clamping area 10 for clamping the culture dish 9 is formed together with the positioning grooves 4, inclined surfaces 13 are arranged on opposite surfaces of the two positioning plates 7, and the inclined surfaces 13 between the two positioning plates 7 are splayed inclined surfaces which gradually open and gradually shrink from one end of the bending part 12 to one end of the positioning part 8; in actual use, the culture dish 9 for culturing microorganism samples is pushed backwards along the inclined plane 13 from the front ends of the two positioning plates 7, the culture dish 9 can simultaneously press the two positioning plates 7 along the inclined plane 13 in the pushing process, the two positioning plates 7 are forced to move towards two sides along the slide way 5 in opposite directions, so that the two positioning plates 7 are slowly pushed open until the culture dish 9 is pushed into the positioning groove 4, at the moment, under the rebound action of the two spring rods 6, the two positioning plates 7 synchronously move and reset in opposite directions, and the positioning parts 8 which are close to the positioning groove 4 are utilized for quickly positioning the culture dish 9 in the positioning groove 4.
In order to improve the functionality, the invention also sets up the cleaning function of cleaning the culture dish 9 after finishing the detection on the base 1, as shown in figure 1, set up the chute 14 corresponding to the oblique direction of the locating slot 4 on the top surface of the base 1, the chute 14 is equipped with the friction wheel 15 rolling contact with outer wall surface of the culture dish 9 through the spindle, the friction wheel 15 utilizes its outer wall surface to roll and contact the culture dish 9 in order to make the culture dish 9 rotate in the locating slot 4 synchronously while rotating in the chute 14, because microorganism strain in the culture dish 9 adheres to the bottom of the inner cavity after finishing the detection, the invention sets up the chute 14, can utilize friction effect to drive the friction wheel 15 that the culture dish 9 rotates while setting up in the chute 14, therefore can see that after finishing the detection, shake the hand wheel 20 through the handle 21, make the driving wheel 18 rotate in the chute 14 with the friction wheel 15, and the friction wheel 15 will utilize its friction surface and culture dish 9 to produce friction effect and cause the culture dish 9 to take the microorganism strain in its inner cavity to rotate synchronously, can insert the hard piece into the culture dish 9 and make the bottom of the culture dish 9 and the culture dish 9 to be contacted with the bottom 9 at the same time, the function of cleaning the culture dish 9 can be improved, the function of scraping the culture dish 9 can be rotated at the same time.
As shown in fig. 1 to 7, in order to make the above functions more reasonable, so as to form a cleaning structure for the culture dish 9, therefore, a slide rail 22 perpendicular to the positioning groove 4 is provided on the upright post 2, a lifting frame 23 capable of moving up and down along the slide rail 22 is in sliding fit, a guide rod 24 for guiding the slide rail smoothly is provided in the slide rail 22, the lifting frame 23 penetrates through the guide rod 24, a spring 25 is provided in the slide rail 22, the spring 25 is sleeved on the guide rod 24, one end of the spring 25 is upwards connected to the top end of the slide rail 22, the bottom end of the spring 25 is elastically contacted to the top surface of the lifting frame 23, so that after the lifting frame 23 is lifted to a certain position, the lifting frame can automatically fall back under the action of the spring 25, one end of the lifting frame 23 horizontally extends towards the positioning groove 4 and then is provided with a rotating shaft 26, a bending rod 27 towards the bottom of the inner cavity of the positioning groove 4 is connected at the outer end of the lifting frame 23 through the rotating shaft 26, the length of the bent rod 27 is equal to the radius of the positioning groove 4, when the bent rod 27 rotates around the rotating shaft 26 to be correspondingly positioned above the positioning groove 4 and in the radial direction of the positioning groove 4, the bent rod 27 falls into the culture dish 9 under the elastic action of the spring 25 and the guiding action of the guide rod 24, a scratch groove 28 formed between the side part and the top surface of the bent rod 27 correspondingly positioned in the culture dish 9, the culture dish 9 is rubbed by the friction wheel 15 to rotate in the positioning groove 4, scratch is generated between the bent rod 27 and the bottom surface of the inner cavity of the culture dish 9, thus a microbial strain sample after being used in detection on the bottom surface of the inner cavity of the culture dish 9 is scraped downwards, the scraped sample reaches the top of the bent rod 27 along the scratch groove 28 and enters the collecting cover 29 and correspondingly positioned on the suction port 31 of the suction cover 30, and when the dust collector 32 is electrified and works, the scraped sample is then sucked along the pipette 33 for cleaning.
The plane 34 positioned at the front end of the slide rail 22 is arranged on the upright post 2, the limiting plate 35 corresponding to one side of the bent rod 27 is fixed on the plane 34, the limiting plate 35 corresponds to the reverse direction of the rotating direction of the bent rod 27, namely, the bent rod 27 rotates to the radial direction along the culture dish 9, when the bent rod 27 extends onto the bottom surface of the inner cavity of the culture dish 9, the bent rod 27 is positioned by the limiting plate 35 positioned at one side of the bent rod 27, and the rotating direction of the culture dish 9 is opposite to the mounting direction of the limiting plate 35, so that the rotation of the bent rod 27 can not be caused even if friction is generated with the bottom end of the bent rod 27 when the culture dish 9 rotates, and the structure is reasonable. After the cleaning operation, the bending bar 27 is lifted upwards from the culture dish 9 so as to be far away from the culture dish 9, and then the bending bar 27 is rotated around the rotating shaft 26 and is accommodated on the base 1.
