Description

Technical Field

[0001] This utility model relates to the technical field of anaerobic bacteria cultivation equipment, and in particular to an anaerobic workstation. Background Technology

[0002] An anaerobic workstation is a laboratory device specifically designed for the cultivation, manipulation, and research of anaerobic bacteria. By precisely controlling the anaerobic environment (oxygen concentration typically below 5 ppm), it provides stable experimental conditions for fields such as microbiology, medicine, food testing, and biopharmaceuticals. Operation of an anaerobic workstation primarily relies on the front glove, which extends into the chamber to isolate the external environment and prevent oxygen from entering. Currently, two common glove structures are available: traditional long-sleeved gloves with fingers are the most common. While simple to use, these gloves are not very convenient due to their thickness. Furthermore, existing anaerobic workstations require placing the culture dishes into a transfer chamber on one side of the device for anaerobic treatment. After treatment, the inner door of the transfer chamber is opened from the main chamber to transfer the culture dishes to the main chamber for culturing. This process has low efficiency in transferring culture dishes, impacting experimental efficiency.

[0003] In conclusion, developing an anaerobic workstation capable of being operated with bare hands and having the function of rapidly transferring culture dishes is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this utility model is to provide an anaerobic workstation that solves the technical problem that traditional anaerobic workstations require operators to put their hands inside sealed gloves for operation, and the thick sealed gloves cause inconvenience in operation.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] This application provides an anaerobic workstation; please refer to the attached instruction manual. Figure 1 and 9This utility model includes a box body 1. An operator places a petri dish inside the box body 1 and manipulates it. A larger side wall of the box body 1 is designated as a mounting wall. Two operation windows are provided on the mounting wall, arranged along its length. A first door 2 is located at the edge of the operation window facing away from the inner cavity of the box body 1, and a second door 3 is located at the edge of the operation window closer to the inner cavity of the box body 1. Both the first door 2 and the second door 3 are hinged to the mounting wall, allowing them to be rotated on the mounting wall. The first door 2 is rotated in the direction away from the inner cavity of the box body 1, and the second door 3 is rotated in the direction of the inner cavity of the box body 1. A first locking member and a second locking member are respectively provided on the edge of the first door 2 and the second door 3 that are close to each other. The two are used to lock the first door 2 and the second door 3 respectively. A fingerless glove 4 is detachably provided on the side of the first door 2 away from the box body 1. A tightening cuff 5 is provided on the end of the fingerless glove 4 on the side away from the box body 1. A loading rack 11 is provided on the second door 3. The loading rack 11 is used to place the culture dish to be operated.

[0031] In one embodiment of this application, before operation, the first box door 2 and the second box door 3 are closed, and the operation window is sealed. The operator opens each of the first box doors 2, places the culture dish on the loading rack 11 of the second box door 3, then closes each of the first box doors 2 and installs fingerless gloves 4 on the outer edge of the first box door 2. The operator puts his arm into the fingerless gloves 4. As the arm is gradually inserted, the size of the arm that fits against the tightening cuff 5 gradually increases. When the arm is inserted to a certain extent, the tightening cuff 5, which has been stretched open, tightens on the outside of the arm. The arm, the tightening cuff 5, the fingerless gloves 4, and the box body 1 form a closed space, which can ensure that the oxygen content in the cavity of the anaerobic workstation is always within the specified range after anaerobic treatment. The operator opens the second locking piece inside the fingerless gloves 4 and pushes the second box door 3 to flip into the cavity of the box body 1, thereby transferring the culture dish to the inside of the box body 1. The operator removes the culture dish from the loading rack 11 and places it on the bottom surface of the cavity of the box body 1 to perform anaerobic operation on the culture dish. The anaerobic workstation provided in this application is equipped with a second door 3 that can pre-load culture dishes. The first door 2 forms a sealed space outside the second door 3, enabling the culture dishes to be carried out simultaneously with the anaerobic operation outside the arm. The culture dishes can be transferred by flipping the second door 3 without opening the transfer chamber door, which avoids the entry of outside air and simplifies the experimental operation.

[0032] Please refer to the instruction manual appendix. Figures 2 to 4Two first hinge members 21 are provided on the outer side of the mounting wall. Each first hinge member 21 is vertically arranged and located on the opposite edge of each operating window. Each first hinge member 21 includes two positioning blocks 211. Furthermore, a connecting rod 212 extends from the opposite end of each positioning block 211. The diameter of the connecting rod 212 is smaller than the width of the positioning block 211. Correspondingly, a first connecting block 22 is provided on the edge of each first door 2. A connecting groove is provided on the two side walls of the first connecting block 22 perpendicular to the height direction of the box body 1. When the first connecting block 22 is placed between the two positioning blocks 211, each connecting rod 212 extends into the connecting groove and can rotate axially within the connecting groove to realize the first door The flipping of 2 corresponds to the provision of two second hinge members 31 on the inner side of the mounting wall. The positions of the second hinge members 31 and the first hinge member 21 are opposite, that is, the rotation axes of the first hinge member 21 and the second hinge member 31 are symmetrically distributed on both sides of the mounting wall. Preferably, the second hinge member 31 includes an abutment block 311, and an insertion rod 312 extends upward from the abutment block 311. The diameter of the insertion rod 312 gradually decreases in the direction away from the abutment block 311, so that the end of the insertion rod 312 has a pointed cone. A second mating block 32 is provided at the edge of the second door 3. An insertion groove is provided on the lower end face of the second mating block 32. The insertion groove is mated with the insertion rod 312, and the insertion rod 312 can rotate axially within the insertion groove.

[0033] Preferably, a connecting bolt is provided between the positioning block 211 and the abutment block 311, and a connecting nut is provided on the side of the connecting bolt near the second door 3. By tightening the connecting nut, the head of the connecting nut and the connecting bolt clamps the mounting wall, and the first hinge 21 and the second hinge 31 are tightly fitted with the mounting wall to ensure the stability of the position of the first door 2 and the second door 3.

[0034] It should be noted that, compared with the first docking block 22, the second docking block 32 is provided with an insertion groove at the lower end. Pushing the second box door 3 upward can separate the second box door 3 from the second hinge 31. In another embodiment of this application, after the operator opens the second box door 3, he / she takes off the culture dish and pushes the second box door 3 upward to remove the second box door 3 from the mounting wall and places it horizontally on the bottom surface of the box body 1 to prevent the second box door 3 from occupying the space inside the box body 1 and affecting the conduct of the anaerobic experiment.

After the locking knob 62 is in contact with the first door 2, it presses the first door 2, so that the first door 2 is in close contact with the edge of the mounting wall. Similarly, a second locking element is provided on the side wall of the second door 3. The second locking element includes a rotating seat fixedly connected to the box body 1. A swing rod 71 is provided inside the rotating seat. A rotating shaft is passed through the side wall of the rotating seat. The rotating shaft is arranged along the length direction of the box body 1 and is perpendicularly inserted into the swing rod 71, so that the swing rod 71 can swing on the side wall of the second door 3. A clamping block 72 is threadedly connected to the end of the swing rod 71. A plate extends from the mounting wall into the inside of the first door 2. A slot plate 8 is provided along the edge of the plate. A locking groove is provided on one side edge in the height direction. After rotating the swing rod 71, it can be locked into the locking groove. Then, the clamping block 72 is screwed inward to the inside of the box 1. The clamping block 72 presses against the mounting wall, so that the clamping block 72 abuts against the second box, completing the closure of the operating window. When it is necessary to open the second box door 3, the clamping block 72 is screwed in the opposite direction to separate the second box door 3 from the clamping block 72. Then, the swing rod 71 is flipped in the direction close to the locking groove port. After the swing rod 71 and the clamping block 72 are moved out of the locking groove, the second box door 3 can be opened.

[0036] Please refer to the instruction manual appendix. Figure 6 The first door 2 and the second door 3 are provided with sealing grooves 9 on their opposite side walls. Sealing rings are provided in the sealing grooves 9. When the locking knob 62 and the pressing block 72 press the first door 2 and the second door 3, the sealing rings of both are tightly fitted with the edge of the operating window, which improves the sealing performance of this application and prevents outside air from entering the box 1.

[0037] It should be noted that a connecting cylinder is provided on the side wall of the first door 2. The edge of the connecting cylinder coincides with the edge of the operating window. The fingerless glove 4 is located on the outside of the connecting cylinder. Several snap-fit ​​grooves 10 are provided on the outer wall of the connecting cylinder.
