DETAILED DESCRIPTION

[0022] 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.

[0023] For example, Figure 1As shown, a mobile laminar flow vehicle includes a support frame 2 and a laminar flow hood 1. The laminar flow hood 1 is fixed to the upper end of the support frame 2, and the lower end of the support frame 2 is provided with casters 202. The front and rear sides of the support frame 2 are provided with shielding curtains 5, as shown. Figure 2 As shown, the support frame 2 has fixed plates 3 on both sides. The lower inner side of the fixed plate 3 is closely attached to the height-adjustable movable plate 4. The inner side of the movable plate 4 is connected to the movable frame 6, which slides with the support frame 2. When moving, the height of the movable plate 4 can be adjusted by the movable frame 6 to prevent collisions.

[0024] For easy replacement and cleaning, the blind curtain 5 is connected to the support frame 2 via Velcro. The blind curtain 5 can be made of PVC transparent soft board or other soft transparent materials, which makes it easy to enter and allows observation of the interior.

[0025] To facilitate the transfer of the laminar flow vehicle, a handle 201 is provided on one side of the support frame 2, and the laminar flow vehicle can be moved laterally by pushing the handle 201.

[0026] like Figure 3 As shown, the movable frame 6 includes two parallel crossbars 601 connected together. The side wall of the support frame 2 is provided with a sliding groove 203. The two ends of the crossbars 601 are provided with hooks 602 that cooperate with the sliding grooves 203. The hooks 602 can hold the two uprights of the support frame 2, improving the overall stability. The side wall of the crossbars 601 is provided with a locking plate 603. The locking plate 603 is provided with a locking bolt 604 that is connected to the support frame 2, which can fix the movable frame 6.

[0027] To improve the convenience and reliability of fixing, the support frame 2 is provided with a positioning hole 204 that cooperates with the locking bolt 604. After the locking bolt 604 cooperates with the positioning hole 204, the movable frame 6 can be positioned without the need for force to tighten.
