[0003] In order to meet the needs of local purification, in the fields of pharmaceuticals, glove box designs are often used to help workers operate. After the production is completed, in order to ensure the cleanliness of the inside of the glove box, the long gloves need to be turned outward. The turned-out long gloves will hang outside the laminar flow hood. Due to the loss of protection, the long gloves located on the outside will only need some minor damage, which will have a greater impact on the final result.
[0004] Therefore, we propose a laminar flow hood for clean workshop production to solve the above problems. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] like Figure 1 As shown, a laminar flow hood for clean workshop production includes a laminar flow hood body 1, a side wall of the laminar flow hood body 1 is provided with two through holes, long gloves 2 are respectively installed in the two through holes, and the side wall of the laminar flow hood body 1 on the side where the through holes are located is rotatably connected to two symmetrical baffles 3, and the top walls of the two baffles 3 are respectively fixedly connected to shields 4, the cross section of the baffles 3 is arc-shaped, and the inferior arc surface of the baffles 3 faces the direction of the through holes. The cross section of the shield 4 is also arc-shaped, and the turned-out long gloves 2 will hang outside the laminar flow hood body 1, and the arc-shaped shields 4 and baffles 3 can clamp the position of the long gloves 2 while leaving enough space for the long gloves 2 to avoid excessive pressure on the long gloves 2 and causing damage to the long gloves 2.
[0022] Reference Figure 2 A through hole 11 is provided on the side wall of the laminar flow hood body 1, and the arc-shaped rack 6 passes through the through hole 11. The length of the through hole 11 is greater than the horizontal distance between the two ends of the arc-shaped rack 6. The length of the through hole 11 ensures that it will not affect the outward movement of the arc-shaped rack 6. During the rotation of the baffle 3, the arc-shaped rack 6 will also move horizontally.
[0023] Reference Figure 3 and Figure 4 The bottom wall of the laminar flow hood body 1 is provided with a cavity, and two limiting mechanisms for fixing the positions of the two baffles 3 are installed in the cavity. The limiting mechanism includes an arc-shaped rack 6, a rotating gear 7, a center rod 8 and two sliding plates 9. One end of the arc-shaped rack 6 is fixedly connected to the side wall of the baffle 3 facing the side wall of the laminar flow hood body 1, and the arc-shaped rack 6 passes through a through hole 11 and is fixedly connected to the side wall of the baffle 3. The bottom wall and the top wall of the cavity are respectively provided with a motion groove 10, and the two sliding plates 9 are respectively slidably connected to the inner walls of the two motion grooves 10, and the two ends of the center rod 8 are respectively rotatably connected to the side walls of the two sliding plates 9, and the center rod 8 passes through the rotating gear 7, and the rotating gear 7 is meshed with the arc-shaped rack 6.
[0024] The side wall of the laminar flow hood body 1 is provided with an insertion rod 5, the cross section of the insertion rod 5 is "U"-shaped, both ends of the insertion rod 5 are inserted into the cavity, and the side walls of the two sliding plates 9 close to the insertion rod 5 are respectively provided with insertion holes 12, and the two ends of the insertion rod 5 passing through the cavity are respectively inserted into the two insertion holes 12, and the depth of the insertion hole 12 is less than the width of the sliding plate 9, so the insertion rod 5 will not penetrate the sliding plate 9. A stopper 13 is fixedly connected between the two ends of the insertion rod 5 in the cavity, and the thickness of the stopper 13 is greater than the thickness of the sliding plate 9, and a spring 14 is fixedly connected between the two sliding plates 9, and the spring 14 allows the rotating gear 7 to maintain a contact state with the arc-shaped rack 6.
[0025] The working principle is as follows: when the work of the laminar flow hood body 1 is finished, the staff can turn the long gloves 2 outward and then pull out the plug rod 5. After the plug rod 5 leaves the socket 12, the movement of the sliding plate 9 will not be restricted. At this time, the baffle 3 and the shield 4 are rotated again to make the arc-shaped rack 6 move out of the through hole 11. Under the action of the spring 14, the sliding plate 9 will always keep the rotating gear 7 in contact with the arc-shaped rack 6. Then the staff can put the long gloves 2 into the shield 4 and the baffle 3. After the staff buckles the baffle 3 and the shield 4 back to their original position, the staff reinserts the plug rod 5. The plug rod 5 is inserted into the socket 12 again, so that the position of the sliding plate 9 can be fixed, thereby ensuring that the protection of the long gloves 2 is more stringent.
[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
