DETAILED DESCRIPTION

[0022] The following is a detailed description of a temperature and humidity controllable microbial incubator for food quality testing provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0023] A temperature and humidity controllable microbial incubator for food quality testing, such as Figure 1-Figure 4 , Figure 6 and Figure 7As shown, it includes: a box body 1, the box body 1 is rotatably connected to a box door 2, a temperature control device and a humidity control device are arranged in the box body 1, a plurality of slide rails 3 are arranged in the box body 1, a mounting plate 4 is slidably connected between two slide rails 3 located at the same level, and the mounting plate 4 is rotatably connected to two symmetrically distributed rotating members 5; first transmission members 6, the number of which is consistent with the number of rotating members 5, and are respectively fixed to adjacent rotating members 5, a second transmission member 7 is arranged between two adjacent first transmission members 6, and the second transmission member 7 is provided with a plurality of evenly distributed supporting plates 8; there is a gap between two adjacent supporting plates 8 for observing the condition of the culture dish.

[0024] In the above scheme, the culture dishes in the device are intended to be easier to take and put. There are four slide rails 3 in the figure, two mounting plates 4, the first transmission member 6 can be a sprocket or a pulley, the second transmission member 7 can be a chain or a belt, there are ten bearing plates 8 in the figure, and there is a gap between two adjacent bearing plates 8, so that the culture dishes located relatively outside will not block the culture dishes located relatively inside, so that the culture dishes located relatively inside can also be easily observed.

[0025] Further, such as Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, it also includes: third transmission members 9, the number of which is consistent with the number of second transmission members 7, which are rotatably connected to adjacent mounting plates 4, a spring is arranged between the third transmission member 9 and the adjacent rotating member 5, a plurality of fixed plates 10 are fixedly connected in the box body 1, the number of fixed plates 10 is consistent with the number of third transmission members 9, the fixed plates 10 are rotatably connected to fourth transmission members 11, and the third transmission member 9 is transmission-connected to the adjacent fourth transmission member 11; a gear box 12 is fixedly connected to the outer side of the box body 1, the number of output shafts of the gear box 12 is consistent with the fourth transmission members 11, the output shaft of the gear box 12 is transmission-connected to the adjacent fourth transmission member 11, a transmission shaft 13 is rotationally connected to the outer side of the box body 1, a one-way wheel is arranged between the input shaft of the gear box 12 and the transmission shaft 13, the box door 2 is provided with a rotating shaft, and the transmission shaft 13 is transmission-connected to the rotating shaft of the box door 2.

[0026] In the above scheme, the load-bearing plate 8 is intended to be able to shift automatically. The third transmission member 9 and the fourth transmission member 11 are driven by friction, the spring between the third transmission member 9 and the rotating member 5 on the left is used to store force and drive the rotating member 5 to rotate, the two output shafts of the gear box 12 rotate in the same direction, the output shaft of the gear box 12 and the adjacent fourth transmission member 11 are driven by a bevel gear set, the one-way wheel between the input shaft of the gear box 12 and the transmission shaft 13 is used to make the output shaft of the gear box 12 rotate only in the same direction, thereby preventing the third transmission member 9 from rotating in the opposite direction, and the transmission shaft 13 and the rotating shaft of the door 2 are driven by a bevel gear set.

[0027] Further, such as Figure 3 and Figure 5 As shown, it also includes: first limiting columns 101, the number of which is consistent with the number of mounting plates 4, the first limiting columns 101 are slidably connected to the box body 1, a first spring is arranged between the first limiting columns 101 and the box body 1, the mounting plate 4 is provided with a first groove, and the first limiting column 101 is inserted into the first groove to limit the mounting plate 4.

[0028] In the above scheme, the third transmission member 9 is intended to keep in contact with the fourth transmission member 11. The first limiting column 101 is composed of a cylinder and a hemisphere, and the first spring between the first limiting column 101 and the box body 1 is initially in a compressed state, so that the first limiting column 101 limits the mounting plate 4.

[0029] Further, such as Figure 8 and Fig. 9 As shown, it also includes: a pawl 14, the number of which is consistent with the number of mounting plates 4, the pawl 14 is rotatably connected to the adjacent mounting plates 4, the third transmission member 9 is provided with circumferentially distributed limiting grooves, a torsion spring is provided between the pawl 14 and the adjacent mounting plates 4, and the pawl 14 is inserted into the adjacent limiting groove to limit the third transmission member 9.

[0030] In the above scheme, the purpose is to prevent the mainspring between the third transmission member 9 and the rotating member 5 from slackening. When the third transmission member 9 rotates forward, the mainspring adjacent to it accumulates force and squeezes the pawl 14 to rotate, so that the pawl 14 does not block the rotation of the third transmission member 9, and the pawl 14 abuts against the limiting groove of the third transmission member 9 to prevent the third transmission member 9 from reversing.

[0031] Further, such as Figure 2 , Figure 4 and Figure 6 As shown, it also includes: support plates 15, the number of which is consistent with the number of mounting plates 4, fixedly connected to the adjacent mounting plates 4; friction blocks 16, the number of which is consistent with the number of mounting plates 4, slidably connected to the adjacent support plates 15, and the friction blocks 16 are used to brake the adjacent second transmission members 7; first sliding members 17, the number of which is consistent with the number of mounting plates 4, slidably connected to the adjacent support plates 15, a second spring is arranged between the first sliding member 17 and the adjacent friction block 16, and a third spring is arranged between the first sliding member 17 and the adjacent support plate 15.

[0032] In the above scheme, the second transmission member 7 is intended to be braked. The support plate 15 provides support for the carrier plate 8 so that the carrier plate 8 is more stable when carrying the culture dish. The friction block 16 is used to brake the second transmission member 7. When the pressure of the friction block 16 on the second transmission member 7 is sufficient, the second transmission member 7 cannot rotate. When the pressure of the friction block 16 on the second transmission member 7 is insufficient, the second transmission member 7 rotates. The first sliding member 17 is composed of a slider and a round rod. The elastic coefficient of the third spring adjacent to the first sliding member 17 is greater than the elastic coefficient of the second spring, so that after the first sliding member 17 moves and compresses the adjacent third spring, the elastic force of the second spring between the friction block 16 and the first sliding member 17 is greatly reduced, thereby reducing the resistance of the friction block 16 to the second transmission member 7, so that the second transmission member 7 can rotate.

[0033] Further, such as Figure 7 As shown, it also includes: second limiting columns 18, the number of which is consistent with the number of mounting plates 4, the second limiting columns 18 are slidably connected to the adjacent mounting plates 4, a fourth spring is arranged between the second limiting columns 18 and the adjacent mounting plates 4, and the rotating member 5 adjacent to the second limiting columns 18 is provided with circumferentially distributed second grooves, the number of the second grooves is consistent with the number of the supporting plates 8, and the second limiting columns 18 are inserted into the adjacent second grooves on the adjacent rotating member 5 to limit it.

[0034] In the above scheme, the purpose is to position the bearing plate 8. The second limiting column 18 is composed of a round rod and a hemisphere. The fourth spring between the second limiting column 18 and the mounting plate 4 is initially in a compressed state, so that the second limiting column 18 limits the rotating member 5. When the first sliding member 17 is in the original position, the second transmission member 7 is subjected to the resistance of the friction block 16 while the rotating member 5 is limited by the second limiting column 18. The resistance at this time makes it impossible for the spring between the third transmission member 9 and the rotating member 5 to drive the rotating member 5 to rotate. When the first sliding member 17 moves, the resistance between the friction block 16 and the second transmission member 7 is reduced, so that the second transmission member 7 can rotate. When the first sliding member 17 is in the original position but the second limiting column 18 is not inserted into the second groove of the rotating member 5, the second transmission member 7 can still rotate due to insufficient resistance.

[0035] Working process: When using this device, first punch the box door 2. When the box door 2 is opened, the transmission shaft 13 is driven to rotate through the adjacent bevel gear group. The transmission shaft 13 drives the input shaft of the gear box 12 to rotate through the one-way wheel. The output shaft of the gear box 12 drives the two output shafts to rotate. The two output shafts of the gear box 12 drive the two fourth transmission members 11 to rotate through the adjacent bevel gear groups. The fourth transmission member 11 drives the adjacent third transmission member 9 to rotate through friction. When the third transmission member 9 rotates, the adjacent spring accumulates force. At the same time, the third transmission member 9 squeezes the pawl 14 to make it rotate. When the pawl 14 rotates, the adjacent torsion spring accumulates force. When the third transmission member 9 stops rotating, the pawl 14 is inserted into the limit groove on the third transmission member 9 under the action of the adjacent torsion spring, thereby preventing the third transmission member 9 from reversing.

[0036] After the box door 2 is opened, the mounting plate 4 is pulled outward. When the mounting plate 4 moves, it squeezes the adjacent first limiting column 101. The first limiting column 101 is separated from the first groove on the mounting plate 4 and compresses the adjacent first spring. When the mounting plate 4 is pulled out, the culture dish can be placed or removed on the carrying plate 8. When the carrying plate 8 on the front side is full, the first sliding member 17 is pulled. The first sliding member 17 compresses the adjacent third spring and relaxes the second spring between the first sliding member 17 and the friction block 16, thereby reducing the friction force of the friction block 16 on the second transmission member 7. At this time, the rotating member 5 on the left side rotates under the action of the adjacent spring, and the rotating member 5 on the left side drives the first transmission member 6 on the left side to rotate, the first transmission member 6 on the left side drives the second transmission member 7 to rotate, and the second transmission member 7 drives the The first transmission member 6 and the rotating member 5 rotate, and the rotating member 5 on the right side squeezes the second limit column 18 when rotating, and the second limit column 18 squeezes the adjacent fourth spring. When the rear supporting plate 8 rotates to the front side, the first sliding member 17 is released, and the third spring adjacent to the first sliding member 17 pushes the first sliding member 17 to reset, so that the first sliding member 17 compresses the second spring between it and the friction block 16, and then the friction block 16 squeezes the second transmission member 7 to increase the friction force between the two. When the rotating member 5 on the right side rotates until the second limit column 18 is aligned with the second groove thereon, the second limit column 18 is inserted into the second groove on the rotating member 5. At this time, the rotating member 5 and the second transmission member 7 stop rotating under the limitation of the second limit column 18 and the friction of the friction block 16.

[0037] When the culture dish is taken and placed, the mounting plate 4 is pushed back to its original position, and the first limiting column 101 limits the mounting plate 4 again, thereby ensuring that the third transmission member 9 and the fourth transmission member 11 maintain contact, and then the box door 2 is closed. When the box door 2 is closed, the box door 2 drives the transmission shaft 13 to rotate through the bevel gear set. Due to the effect of the one-way wheel, the transmission shaft 13 will not drive the input shaft of the gear box 12 to rotate.

[0038] Further, such as Figure 4 , Fig.10 and Fig.11 As shown, it also includes: clamping members 19, the number of which is twice the number of the carrier plates 8, two adjacent clamping members 19 are fixed to the same carrier plate 8, the clamping members 19 are slidably connected to the second sliding member 20, the second sliding member 20 is slidably connected to the third sliding member 21, and a fifth spring is arranged between the third sliding member 21 and the second sliding member 20; the number of clamping blocks 22 is the same as the number of the clamping members 19, and the clamping blocks 22 are fixed to the adjacent third sliding members 21. The lower side of the clamping block 22 is provided with an inclined surface.

[0039] In the above scheme, the stacked culture dishes are blocked to prevent the stacked culture dishes from falling. The facing sides of two adjacent clamping members 19 are provided with concave arc surfaces to adapt to the shape of the culture dish, but the shortest distance between the two adjacent clamping members 19 is less than the diameter of the culture dish, and the maximum distance between the two adjacent clamping members 19 is greater than the diameter of the culture dish, so that when the culture dish is located between the two adjacent clamping members 19, there is a certain gap between the culture dish and the clamping member 19, but the culture dish cannot be moved out from between the two adjacent clamping members 19 when the force is small. The facing sides of the two adjacent clamping members 19 have a certain elasticity, so that the culture dish can be squeezed into between the two adjacent clamping members 19, and the third sliding member 21 is composed of a round rod and two discs. The inclined surface of the lower side of the clamping block 22 is inserted between the two adjacent culture dishes, so that the culture dish to be taken is protected from being squeezed by the upper culture dish, making it easier to take out.

[0040] Further, such as Figure 4 , Fig.10 and Fig.11 As shown, it also includes: extrusion members 23, the number of which is consistent with the number of the bearing plates 8, the extrusion members 23 are slidably connected to the adjacent third sliding members 21, and a sixth spring is arranged between the extrusion members 23 and the third sliding members 21.

[0041] In the above scheme, the purpose is to push out the culture dish to be taken, so that it is more convenient to take out the culture dish. The extrusion piece 23 is divided into a vertical part and a horizontal part. The horizontal part of the extrusion piece 23 is used to push the culture dish to be taken. The horizontal part of the extrusion piece 23 is lower than the lower side of the clamping block 22. The elastic coefficient of the sixth spring between the extrusion piece 23 and the third sliding piece 21 is greater than the elastic coefficient of the fifth spring between the third sliding piece 21 and the second sliding piece 20, so that the clamping block 22 first clamps the culture dish on the upper side of the culture dish to be taken, and then the pressing piece 23 pushes the culture dish to be taken to move.

[0042] Workflow: When placing a culture dish, squeeze the culture dish between the two clamping members 19. The culture dish is prevented from shifting under the blocking of the two adjacent clamping members 19. When taking the culture dish stacked in the middle, use the thumb and index finger (or other fingers), one of which presses the third sliding member 21 on the left (such as Fig.10As shown), the other hand presses the squeezing member 23, first moves up and down to the upper side of the culture dish to be taken, and then uses force with two fingers, the squeezing member 23 pushes the third sliding member 21 through the adjacent sixth spring, and the two adjacent third sliding members 21 drive the clamping block 22 to move, and the clamping block 22 squeezes the culture dish on the upper side of the culture dish to be taken, thereby lifting several culture dishes on the upper side of the culture dish to be taken, and then the two clamping blocks 22 clamp the culture dishes on the upper side of the culture dish to be taken, at this time, the squeezing member 23 contacts the culture dish to be taken, and then continue to apply force to make the squeezing member 23 continue to move, the squeezing member 23 compresses the sixth spring adjacent to it, and the squeezing member 23 squeezes the culture dish to be taken and moves forward, thereby pushing out the culture dish to be taken, so as to facilitate taking it out, and then the other hand takes out the culture dish to be taken, and then releases the two fingers, the squeezing member 23 is reset under the action of the adjacent sixth spring, and then the two third sliding members 21 are reset under the action of the adjacent fifth spring, so that the clamping block 22 is separated from the culture dish, and then the culture dish falls and is stacked again.

[0043] The present invention provides a thought and method. There are many methods and ways to implement the technical solution. The above is only the preferred implementation mode of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
