[0021] Please refer to Figures 1-4 For this utility model, a technical solution for the docking structure of the transition bin of a glove box is provided: It includes a support frame 1, a glove box body 2 fixedly installed on the outer top of the support frame 1, and an annular transition bin 3 arranged at the bottom of the outer side wall of the glove box body 2. A connection ring 4 is installed through the bottom of the outer side wall of the glove box body 2 near one end of the annular transition bin 3. A first square opening 5 arranged in an annular and equally spaced manner is opened on the outer side wall of the connection ring 4. Straight plates 6 that are mutually consistent with the first square opening 5 are fixedly installed at equal intervals on the outer side wall of the annular filter bin. And an insertion opening 7 is opened at one end of the outer top of the straight plate 6. A fixing component for limiting the annular filter bin is arranged on the outer peripheral side wall of the connection ring 4 and outside the glove box body 2. The fixing component includes an annular connecting frame 8 fixedly installed on the outer peripheral side wall of the connection ring 4. Sliding bases 9 are fixedly installed at equal intervals on the inner bottom surface of the annular connecting frame 8. Semi-open sliding grooves 10 are opened on the outer top of the three groups of sliding bases 9. And a limiting long block 11 is slidably connected to the inner side of the sliding groove 10. At the same time, through-open openings 12 that are mutually consistent with the limiting long block 11 are opened at equal intervals on the inner peripheral side wall of the annular connecting frame 8. A second square opening 13 that is mutually communicated with the first square opening 5 and mutually consistent with the opening 12 is opened on the outer peripheral side wall of the connection ring 4. A rotating disk 14 is rotatably connected to the inner side wall of the annular connecting frame 8 and on the outer top of the three groups of sliding bases 9. Through-open arc grooves 15 arranged in an annular and equally spaced manner are opened on the outer top of the rotating disk 14. Connecting rods 16 are slidably connected to the inner sides of the three groups of arc grooves 15. One ends of the three connecting rods 16 are fixedly connected to the outer top of the limiting long block 11. A first gear 17 is fixedly installed on the outer peripheral side wall of the rotating disk 14. A rotating shaft rod 18 is rotatably connected to the inner bottom surface of the annular connecting frame 8. A second gear 19 is fixedly installed on the outer peripheral surface of the rotating shaft rod 18. The first gear 17 and the second gear 19 are meshed. A sealing ring is fixedly installed on the outer top of the annular connecting frame 8. One end of the rotating shaft rod 18 penetrates through the sealing ring and extends to the outer top of the sealing ring and is fixedly installed with a knob 20. When docking, first align the straight plate 6 with the first square opening 5, and push the annular transition bin 3 so that the straight plate 6 is inserted into the inner side of the first square opening 5. Immediately afterwards, turn the knob 20 to drive the rotating shaft rod 18 to drive the first gear 17 to rotate. Then, under the meshing characteristics of the gears, the second gear 19 drives the rotating disk 14 to rotate inside the annular connecting frame 8, so that the connecting rod 16 slides back and forth in the arc groove 15, and drives the limiting long block 11 to slide out of the outer part of the annular connecting frame 8 along the sliding groove 10 and the opening 12, extends into the inner part of the first square opening 5 through the second square opening 13, and is inserted into the inner side of the insertion opening 7 on the straight plate 6 to limit the straight plate 6, so as to fix the annular transition bin 3 and the connection ring 4 to each other. And while completing the fixation of the annular transition bin 3, it is also convenient to maintain and replace the annular transition bin, improving the stability and flexibility of the use of this device and increasing the use efficiency.

[0022] On the outer peripheral side walls of the connecting ring 4 and the annular transition bin 3 corresponding to each other, they are fixedly connected to each other through a seal. The seal includes first connecting blocks 21 fixedly installed at both ends of the outer peripheral side wall of the connecting ring 4. On the outer peripheral side wall of the annular transition bin 3 and near one end of the connecting ring 4, a second connecting block 22 corresponding to the first connecting block 21 is fixedly installed. Through holes in the form of through holes are provided on the outer tops of the first connecting block 21 and the second connecting block 22. A threaded rod 23 is commonly connected in the through holes of the first connecting block 21 and the second connecting block 22. Pulling rings 24 are fixedly installed on the outer tops of the two threaded rods 23. After the annular transition bin 3 is fixed on the connecting ring 4, by turning the pulling ring 24, the threaded rod 23 rotates and moves inside the through hole of the second connecting block 22 and moves into the through hole of the first connecting block 21, so that the first connecting block 21 and the second connecting block 22 are fixedly connected to each other, and further the connecting ring 4 and the annular transition bin 3 are fixedly sealed, thereby further improving the mutual fixing effect and the applicability of the device.

[0023] One end of the outer side wall of the annular filter bin away from the connecting ring 4 is movably hinged with an annular sealing plate 25 through a hinge. Through holes are provided on the outer side walls of the annular transition bin 3 and the annular sealing plate 25, and bolts 26 are arranged inside the through holes. The arrangement of the annular sealing plate 25 facilitates the staff to place the objects to be detected and experimented into the annular transition bin 3. The bolt 26 tightly connects the annular sealing plate 25 and the annular transition bin 3 through the through hole, improving the experimental sealing performance, and at the same time making it difficult for the annular sealing plate 25 to flip when not in use.

[0024] The working principle of the present utility model is as follows: When in use, the staff first aligns the straight plate 6 on the annular transition bin 3 with the first square opening 5, and pushes the annular transition bin 3 so that the straight plate 6 is inserted into the inner side of the first square opening 5, and the annular transition bin 3 is connected to the connecting ring 4. Then, turn the knob 20 to drive the rotary shaft rod 18 to drive the first gear 17 to rotate. Then, under the meshing characteristics of the gears, the second gear 19 drives the rotary disk 14 to rotate inside the annular connecting frame 8, so that the connecting rod 16 slides back and forth in the arc-shaped groove 15, and drives the limiting long block 11 to slide out of the annular connecting frame 8 along the sliding groove 10 and the opening 12, extend into the inner side of the first square opening 5 through the second square opening 13, and be inserted into the inner side of the socket 7 on the straight plate 6 to limit the straight plate 6, so as to fix the annular transition bin 3 and the connecting ring 4 to each other.

[0025] Meanwhile, after the annular transition bin 3 is fixed on the connecting ring 4, turn the pull ring 24 to make the threaded rod 23 rotate and move inside the first threaded hole on the second connecting block 22, and move it into the first threaded hole of the first connecting block 21, so as to fix the first connecting block 21 and the second connecting block 22 to each other, and further fix and seal the connecting ring 4 and the annular transition bin 3.

[0026] Meanwhile, place the object to be tested and experimented into the annular transition bin 3, and connect the annular sealing plate 25 and the annular transition bin 3 tightly through the second threaded hole with the bolt 26.

[0027] Finally, when it is necessary to disassemble the annular transition bin 3, just reverse the rotation of the knob 20 and the pull ring 24, and then pull the annular transition bin 3 to quickly separate it from the connecting ring 4.

[0028] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
