DETAILED DESCRIPTION

[0040] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present application, and are not used to limit the present application.

[0041] Embodiment: as shown in Figures 1-5 and Figure 8 The self-sterilization type microbial bacteria culture propagation inoculation instrument of the present application comprises a body 1, the upper part of the body 1 is provided with a fixed pressing piece 5, the body 1 is divided into a sterilization cavity and a mounting cavity by a partition plate, a sterilization module 11 capable of killing bacteria is arranged in the sterilization cavity, a cover plate is arranged on the top of the sterilization cavity, and at least two T-shaped positioning cylinders 12 communicating with the sterilization cavity are arranged on the cover plate; the sterilization module 11 can sterilize multiple inoculation tools 3 at the same time;

[0042] At least two inoculation mechanisms are arranged above the sterilization module 11, and the inoculation mechanisms are composed of a transmission support 6, a T-shaped movable part 8 connected to the transmission support 6 through a movable connecting assembly, and an inoculation tool 3 connected to the T-shaped movable part 8; the transmission support 6 comprises a connecting seat 61, and a fixed assembly 7 for fixing the T-shaped movable part 8 is arranged on the connecting seat 61 and used in cooperation with the fixed pressing piece 5;

[0043] A suspension cylinder 2 capable of extending into the sterilization cavity is arranged in the T-shaped positioning cylinder 12; the body 1 and the suspension cylinder 2 can also be used as a storage rack to store the inoculation tool 3;

[0044] A lifting mechanism for driving the inoculation mechanism to lift is arranged in the mounting cavity, and a moving body of the lifting mechanism is connected to the connecting seat 61 through a transmission arm 4.

[0045] In the embodiment, since the inoculation mechanism and the suspension cylinder 2 are not provided with more than one, the inoculation tool 3 can be used alternately, avoiding the waste of time caused by waiting for sterilization, especially for the streaking method which needs to be streaked multiple times, the time can be greatly saved and the work efficiency can be improved.

[0046] In the embodiment, the lifting mechanism can be an electric linear module, one end of the transmission arm 4 is fixed to the slide (i.e. the moving body) of the electric linear module, and the other end is fixed to the connecting seat 61, so that the inoculation mechanism can be lifted by the lifting mechanism.

[0047] In addition, the sterilization module 11 can be one of an electric heating plate, an electric heating wire, an electric heating tube, and an infrared lamp. The bacteria can be killed by supplying power to the electric heating plate or the electric heating wire or the electric heating tube to generate high temperature. At this time, the suspension cylinder 2 is made of high thermal conductivity material, such as copper, stainless steel and the like. The inoculation tool 3 is irradiated by infrared rays generated by the infrared lamp to heat the inoculation tool 3, so that the purpose of killing bacteria can be achieved, and the heating speed is fast. At this time, the suspension cylinder 2 is made of colorless and transparent material, such as glass and the like.

[0048] In the embodiment, a power interface, a controller, a key module, a voice reminding module and the like are also needed to be provided. The above components can be provided on the machine body 1. The controller is electrically connected with the power interface, the key module, the voice reminding module and the lifting mechanism. The voice reminding module is used to remind the user how long the inoculation tool 3 will be unlocked, and performs countdown. The specific installation position and installation method of the power interface, the controller, the key module and the voice reminding module are not limited, so they are not marked in the drawings.

[0049] In addition, the distance between the connecting seat 61 and the fixed pressing piece 5 can be detected by setting a distance sensor electrically connected with the controller. The detection signal from the distance sensor is received by the controller, and the detection signal is processed and analyzed to determine how far the distance between the connecting seat 61 and the fixed pressing piece 5 is and how much time is needed to unlock the inoculation tool 3. Other sensors, such as a speed sensor, can also be used. However, the speed sensor needs to be provided on the connecting seat 61. The sensor can also not be provided, but the speed of the inoculation mechanism driven by the lifting mechanism can be determined.

[0050] Among them, as shown in FIG. 1, Figures 8-11As shown, the fixed assembly 7 comprises a fixed support 71, a movable piece 79 mounted on the inner side of the fixed support 71, and a plug-in column 74 connected with the movable piece 79 through a reinforcing plate 75. The top plate of the fixed support 71 is provided with a movable rod 73 which can be pressed downward by the fixed pressing piece 5. The lower end of the movable rod 73 is provided with a matching cylinder 76, and the lower end of the matching cylinder 76 is provided with an inclined surface. The movable rod 73 is provided with a connecting spring 72 which is used to support the movable rod 73 and enable the movable rod 73 to reset. One end of the top plate of the fixed support 71 is symmetrically provided with a clasp 78, and the bottom of the bottom plate of the fixed support 71 is provided with a limiting boss. One end of the limiting boss is symmetrically provided with a T-shaped sliding strip 77. The reinforcing plate 75 can effectively avoid the deformation of the connecting part two.

[0051] Specifically, as shown in Figures 8-11 , the movable piece 79 comprises a connecting part one, a connecting part two, an elastic part 791, and a rigid abutting part 792 which abuts against the inclined surface. One end of the elastic part 791 is upwardly bent and connected with the lower end of the connecting part one. The other end of the elastic part 791 is downwardly bent and connected with the upper end of the rigid abutting part 792. The lower end of the rigid abutting part 792 is upwardly bent and connected with the lower end of the connecting part two. The connecting part two is provided with a through hole for mounting the plug-in column 74. The through hole is used to mount the plug-in column 74, which is convenient for the connection between the plug-in column 74 and the connecting part two.

[0052] The inoculation mechanism is driven upward by the lifting mechanism. After the movable rod 73 contacts with the fixed pressing piece 5, the movable rod 73 moves downward due to the pressure, so that the connecting spring 72 is in a stretched state. The matching cylinder 76 is driven downward by the movable rod 73, the rigid abutting part 792 is pushed by the matching cylinder 76, the elastic part 791 is extruded by the rigid abutting part 792, and the plug-in column 74 is separated from the plug-in hole 81, thereby completing the unlocking operation of the inoculation tool 3. After one inoculation is completed, and after the inoculation tool 3 is fixed, the operator can start another lifting mechanism to drive another inoculation tool 3 away from the corresponding suspension cylinder 2, which is conducive to the alternate use of the inoculation tool 3.

[0053] As shown in Figure 4 , Figure 7 and Figure 8 , the T-shaped movable piece 8 is a T-shaped column. A threaded blind hole is formed in the large-diameter end of the T-shaped column.

A hanging ring 82 is rotatably connected to the end of the small-diameter end. One end of the holding part of the inoculation tool 3 is provided with a threaded joint 31 which is screwed with the threaded blind hole. The threaded joint 31 is screwed with the threaded blind hole, so that the inoculation tool 3 and the T-shaped movable piece 8 are connected together.

[0054] In addition, the inoculation tool 3 is one or more of an inoculation ring, an inoculation needle, an inoculation shovel, and an inoculation stick, so that the inoculation tool 3 can be suitable for inoculation by different inoculation methods, and an operator can select different inoculation tools 3 as needed, which is very flexible.

The connecting cylinder 62 is provided with a mounting hole at the top for mounting the T-shaped screw rod, and the T-shaped screw rod is fixed to the connecting cylinder 62 through a nut. The connecting cylinder 62 provides support for the installation of the spiral telescopic rope 9, and the connecting cylinder 62 can hide the spiral telescopic rope 9, which is more beautiful.

[0057] As shown in Figure 5 and Figure 6 , the center of the connecting seat 61 is provided with a sliding through hole 63 which is in sliding fit with the small diameter end of the T-shaped movable part 8.

Symmetrical positioning protrusions on the inner wall of the sliding through hole 63 are in sliding fit with the positioning sliding groove 83. Two clamping grooves 66 above the communication hole are in communication with the mounting groove 64 and can be clamped with the clamps 78. The clamping of the clamps 78 and the clamping grooves 66 improves the stability of the installation of the fixed bracket 71. The sliding fit of the positioning protrusions and the positioning sliding groove 83 quickly positions the T-shaped movable part 8.

[0058] As shown in Figures 3-6 , the connecting seat 61 is symmetrically provided with mounting grooves 64 for mounting the fixed bracket 71. The mounting grooves 64 are provided with positioning platforms 65. The positioning platforms 65 are provided with T-shaped sliding grooves in sliding fit with T-shaped sliding strips 77. The bottom of the connecting seat 61 is further provided with a pressing ring 67. The T-shaped positioning cylinder 12 is used in cooperation to fix the suspension cylinder 2.
