DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0018] The utility model provides a kind of biological safety cabinet cabinet body for facilitating installation operation as Figs. 1 to 3 As shown in the figure, a kind of biological safety cabinet cabinet body for facilitating installation operation, including safety cabinet body 1. Safety cabinet body 1 is fixedly arranged bracket 11, bracket 11 is transversely arranged high efficiency filter 12. Bracket 11 and high efficiency filter 12 are together to divide safety cabinet body 1 into two chambers, wherein the chamber located at upper is filter chamber 6, and the chamber located at lower is fresh-keeping chamber 7.

[0019] Two horizontal fixed plates 14 are fixedly arranged on the inner wall of filter chamber 6, and the two fixed plates 14 are symmetrically distributed. The bottom of one of the fixed plates 14 is fixedly arranged with a vertical guide rod 15, and the static pressure box 13 is slidably installed on the guide rod 15, and the static pressure box 13 is pressed onto the high efficiency filter 12 and the bracket 11.

[0020] The other fixed plate 14 is installed with a power assembly, and the power assembly is drivingly connected with the static pressure box 13 to drive the static pressure box 13 to slide up and down.

[0021] The power assembly includes a threaded rod 10, which is vertically arranged in the safety cabinet body 1 and rotatably connected with the safety cabinet body 1. Meanwhile, the threaded rod 10 penetrates downward through the fixed plate 14 where it is located and is rotatably connected with the fixed plate 14 where it is located. The top of the safety cabinet body 1 is fixed with a motor 4 and an exhaust box 5. The output shaft of the motor 4 penetrates into the safety cabinet body 1 and is fixedly connected with the threaded rod 10 coaxially. The threaded rod 10 is threadedly connected with the static pressure box 13, and the static pressure box 13 is limitingly and slidably connected with the guide rod 15.

[0022] Two cabinet doors are movably installed on the safe cabinet body 1. One of the cabinet doors corresponds to the filter chamber 6 and is a first cabinet door 2; the other cabinet door corresponds to the fresh-keeping chamber 7 and is a second cabinet door 3. The first cabinet door 2 is fixed on the safe cabinet body 1 by a plurality of pairs of magnets. Each pair of magnets comprises a first magnet 8 and a second magnet 9, the first magnet 8 is fixedly installed on the first cabinet door 2, and the second magnet 9 is fixedly installed on the safe cabinet body 1. The first magnet 8 and the second magnet 9 are magnetically attracted and matched.

[0023] Two horizontal limiting plates 16 are fixedly arranged on the end face of the safe cabinet body 1. A vertically arranged bolt 18 is slidably penetrated through each of the two fixed plates 14, and a limiting cap is fixedly arranged at the top end of each bolt 18. The limiting cap is limitedly matched with the fixed plate 14.

[0024] The two bolts 18 correspond to the two limiting plates 16 one by one, and each limiting plate 16 is provided with a plug hole in the vertical direction. Each bolt 18 penetrates through the plug hole in the corresponding limiting plate 16 and is limitedly matched with the limiting plate 16.

[0025] The static pressure box 13 is drivenly matched with the bolt 18 by disassembly to push the bolt 18 out of the plug hole in the corresponding limiting plate 16.

[0026] The disassembly part comprises a push plate 20 and a transmission plate 17. The push plate 20 is fixedly connected with the static pressure box 13, and the transmission plate 17 is fixedly connected with the bolt 18. The push plate 20 and the transmission plate 17 are abutted and drivenly matched.

[0027] The spring 19 is sleeved on the bolt 18, the top end of the spring 19 is fixedly connected with the fixed plate 14, and the bottom end of the spring 19 is fixedly connected with the transmission plate 17.

[0028] Working principle: when the high-efficiency filter 12 is disassembled, the motor 4 is started. The output shaft of the motor 4 drives the threaded rod 10 to rotate, the threaded rod 10 pushes the static pressure box 13 to slide upward away from the bracket 11 and the high-efficiency filter 12. The static pressure box 13 drives the two push plates 20 to move upward synchronously.

[0029] When the push plate 20 moves to contact the transmission plate 17, the transmission plate 17 is pushed upward. The transmission plate 17 drives the bolt 18 to slide upward out of the plug hole in the corresponding limiting plate 16, at this time, the two limiting plates 16 on the first cabinet door 2 are released from the limiting. At the same time, the transmission plate 17 compresses the spring 19.

[0030] When the bolt 18 completely slides out of the plug hole in the corresponding limiting plate 16, the first cabinet door 2 is pulled to make the first magnet 8 and the second magnet 9 separate. Then the high-efficiency filter 12 is taken out for cleaning and replacement.

[0031] When installing the high efficiency filter 12, the high efficiency filter 12 is placed on the bracket 11. Then the first magnet 8 and the second magnet 9 are brought into contact and attracted, at which time the first cabinet door 2 is fixedly installed to the safety cabinet body 1.

[0032] After the output shaft of the motor 4 is reversed, the threaded rod 10 pushes the static pressure box 13 to slide down until pressing on the high efficiency filter 12 and the bracket 11. In this process, under the elastic force of the spring 19, the transmission plate 17 drives the bolt 18 to downwardly insert into the insertion hole of the corresponding limiting plate 16.

[0033] Finally, it should be noted that the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
