[0002] A microbial incubator is a device used to culture microorganisms, usually used in laboratories and medical institutions. Its main function is to provide constant temperature, humidity and atmosphere conditions to support the growth and reproduction of microorganisms. A microbial incubator usually consists of a heater, humidity controller, gas controller and observation window. When using a microbial incubator, strict aseptic operation should be observed to avoid contamination and cross infection.

Since multiple culture dishes placed in the microbial incubator are static and motionless, there is a lack of a structure that can allow multiple culture dishes to rotate intermittently, which leads to local accumulation of wind and uneven temperature distribution in the box, affecting the growth of microorganisms in the culture dishes. Therefore, a microbial incubator for microbial detection is needed. Utility Model Content

[0026] Example

[0027] The microbial incubator adopts an upper air vent setting mode, blowing hot air or cold air from the upper part of the box to form a circulating air in the box. Since multiple culture dishes placed in the microbial incubator are static and motionless, there is a lack of a structure that allows multiple culture dishes to rotate intermittently, which leads to the formation of local wind accumulation, resulting in uneven temperature distribution in the box, affecting the growth of microorganisms in the culture dishes.

[0028] To do this, see Figure 1-4 The utility model provides a microorganism culture box for microorganism detection, comprising: a culture box body 1, a mesh plate 2 is fixedly connected to the inner wall of the culture box body 1, a rotating rod 3 is rotatably connected to the mesh plate 2, the top end of the rotating rod 3 is rotatably connected to the top wall of the culture chamber of the culture box body 1, the bottom end of the rotating rod 3 extends to the cavity provided at the bottom of the culture box body 1, and is connected to an intermittent transmission structure 5, and a rotating disk 31 fixedly connected to the outer side of the rotating rod 3 is respectively provided above the mesh plate 2 and above the bottom wall of the culture chamber, and a synchronous positioning structure 4 is connected between the tops of the two rotating disks 31 and the rotating rod 3, and the synchronous positioning structure 4 can facilitate the synchronous clamping and fixing or loosening of multiple culture dishes respectively placed on the tops of the two rotating disks 31;

[0029] The intermittent transmission structure 5 can facilitate intermittent transmission of the two turntables 31 on the rotating rod 3, so that a plurality of culture dishes respectively placed on the two turntables 31 can be intermittently rotated during cultivation.

[0030] Further Figure 1-4As shown, it is worth explaining in detail that, in order to facilitate the synchronous fixation of multiple culture dishes respectively placed on the two turntables 31 and reduce the frequency of manual operation, a synchronous positioning structure 4 is provided, including a lifting rod 41 sliding in an active channel opened on the rotating rod 3, the length of the active channel is greater than the length of the lifting rod 41, the cross-section of the lifting rod 41 is an I-shaped structure, the two side walls of the lifting rod 41 are both arc-shaped structures, the outer side of the lifting rod 41 is fixedly connected to two symmetrically arranged guide rings 42, the outer sides of the two guide rings 42 are hinged with a plurality of push-pull rods 43 arranged in a ring array, and the bottom ends of the push-pull rods 43 are hinged At the top of the slider 44 with a convex structure in vertical section, the sliders 44 are slidably connected to the slide groove provided at the top of the turntable 31, and a clamping plate a45 is fixedly connected to the top of each slider 44. A clamping plate b46 fixedly connected to the top of the turntable 31 is provided on one side of the clamping plate a45. The cooperation between the clamping plate b46 and the clamping plate a45 can facilitate the clamping and fixing of culture dishes of different diameters. A connecting plate 47 is fixedly connected to the top of the guide ring 42 near the top of the lifting rod 41, and a hand screw 48 is movably inserted on the connecting plate 47. A plurality of equidistant screw holes 49 cooperating with the hand screw 48 are provided on the outer side of the rotating rod 3.

[0031] The clamping plates a45 and b46 are arc-shaped structures, and the opposite ends of the two guide rings 42 are flush with the top and bottom ends of the lifting rod 41 respectively.

[0032] Further Figure 1-4 As shown, it is worth explaining in detail that in order to enable the rotating rod 3 to rotate intermittently and to prevent the problem of not braking due to inertia during rotation, an intermittent transmission structure 5 is provided, including a transmission plate 51 fixedly connected to the outer side of the bottom end extension of the rotating rod 3, and a plurality of claw grooves arranged in a ring array are provided on the outer side of the transmission plate 51, and a V-shaped stopping claw 52 is movably overlapped in one of the claw grooves, and the V-shaped stopping claw 52 is rotatably connected to the inner bottom wall of the cavity through a connecting shaft 53, and the outer side of the V-shaped stopping claw 52 is connected to a connecting column a55 through a spring a54, and the bottom end of the connecting column a55 is fixed to the inner bottom wall of the cavity, and one side of the V-shaped stopping claw 52 is also provided with a movable The push claw 56 is overlapped in the other claw groove, and the push claw 56 is rotatably connected to the bottom end of the guide plate 58 through the rotating shaft 57. The bottom end of the push claw 56 is connected to the spring b510 through the connecting column b59. The end of the spring b510 away from the connecting column b59 is fixed to the bottom end of the guide plate 58 through the connecting column c511. The guide plate 58 is slidably sleeved on the outer side of the square slide bar 514, and the square slide bar 514 is fixed in the cavity. A transmission groove 512 is opened on the end of the guide plate 58 away from the square slide bar 514, and an eccentric wheel 513 is movably overlapped in the transmission groove 512. The mounting shaft hole of the eccentric wheel 513 is fixed to the outer side of the output shaft of the motor, and the motor is fixed to the inner bottom wall of the cavity.

After starting The motor causes the eccentric wheel 513 to move in the transmission groove 512, so that the guide plate 58 moves back and forth left and right on the outside of the square slide bar 514, and the transmission disk 51 can be intermittently pushed and operated through the action of the push claw 56 and the spring b510. In addition, with the action of the V-shaped stop claw 52 and the spring a54, the transmission disk 51 will not be unbraked due to inertia during the rotation process, so that the multiple culture dishes arranged on the two turntables 31 are not prone to long-term unchanged position causing local overheating or overcooling of the bottom temperature, thereby ensuring the circulation effect of the air outlet.
