[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The embodiments of the present application solve the problems in the prior art by providing a mobile biosafety laboratory.

[0027] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows: Example 1

[0028] The specific structure of this embodiment is as follows: Figure 1-Figure 4 As shown, a mobile biosafety laboratory comprises:

[0029] The experimental chamber 1, a housing 11 is connected to the middle of the lower part of the experimental chamber 1, a lifting mechanism is arranged inside the housing 11, and a bottom plate 10 is connected to the lower part of the housing 11 through the lifting mechanism;

[0030] A pair of first bearing seats 9 are connected to the front and rear sides of the outer shell 11 below the experimental cavity 1, and a first shaft rod 8 is rotatably connected inside the pair of first bearing seats 9. Both ends of the first shaft rod 8 are connected to rollers 3. A driving mechanism is arranged at the rear side of the outer shell 11 below the experimental cavity 1.

[0031] In some examples, the lifting mechanism includes three second motors 15 connected to the side wall of the shell 11, one end of the output shaft of the second motor 15 is connected to a bidirectional screw 13, one end of the bidirectional screw 13 is connected to a second bearing seat 12, the second bearing seat 12 is fixedly connected to the side wall of the shell 11, and two ball nuts 14 are correspondingly sleeved on the outer side of the bidirectional screw 13, and the bottom of the ball nuts 14 are connected to a second support seat 18, the inside of the second support seat 18 is rotatably connected to a support rod 17, and the end of the support rod 17 is rotatably connected to a first U-shaped seat 16, and the bottom of the first U-shaped seat 16 is fixedly connected to the base plate 10, and the base plate 10 is driven downward by the lifting mechanism until it contacts the ground. As the base plate 10 continues to move downward, it is convenient to lift the experimental chamber 1 and move it away from the ground to a certain height, which is conducive to avoiding the problem that water droplets on the ground can easily penetrate into the laboratory due to the low distance between the experimental chamber 1 and the ground.

[0032] In some examples, a first axial hole 21 and a second axial hole 22 are respectively provided at both ends of the support rod 17, the first axial hole 21 is rotatably connected to the second axial rod 19 inside, both ends of the second axial rod 19 are fixedly connected to the inner wall of the second support seat 18, the second axial hole 22 is rotatably connected to the third axial rod 20 inside, both ends of the third axial rod 20 are fixedly connected to the inner wall of the first U-shaped seat 16, and under the connection action of the first axial hole 21 and the second axial hole 22 and the third axial rod 20, the two ends of the support rod 17 are conveniently rotatably connected to the second support seat 18 and the first U-shaped seat 16 respectively.

[0033] In some examples, a pair of support rods 17 are distributed in an eight-shaped shape, so that when a pair of ball nuts 14 move in opposite directions at the same time, the support effect of the support rods 17 is conducive to driving the base plate 10 at the end of the support rods 17 to move downward.

[0034] In some examples, the three second motors 15 are evenly spaced from left to right, which is beneficial for evenly distributing the pressure applied to the inside of the base plate 10 by the support rods 17. By reasonably distributing the pressure points, the overall pressure resistance of the base plate 10 can be improved.

[0035] The utility model controls and starts the three second motors 15 at the same time, drives the three bidirectional screws 13 to rotate, and drives a pair of ball nuts 14 on the outer sides of the bidirectional screws 13 to move backwards at the same time. Under the support effect of the support rod 17, it is conducive to driving the bottom plate 10 at the end of the support rod 17 to move downward until it contacts the ground. As the bottom plate 10 continues to move downward, it is convenient to lift the experimental chamber 1 and move it away from the ground to a certain height, which is conducive to avoiding the problem that water droplets on the ground can easily penetrate into the interior of the laboratory due to the low distance between the experimental chamber 1 and the ground.

[0037] In some examples, the top of the experimental chamber 1 is connected to lifting rings 2 at the four corners. By providing the lifting rings 2, it is convenient to lift the experimental chamber 1 by a crane.

[0038] The utility model starts the first motor 5 to drive the first gear 6 to rotate, and through the connection between the first gear 6 and the second gear 7, drives the second gear 7 and the first shaft 8 to rotate, and then drives the rollers 3 at both ends to rotate, which is conducive to driving the entire experimental chamber 1 to move.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
