When a student pulls the bed plate 7 to swing upwards, the bed plate 7 swings upwards to drive the movable rack 112 to swing upwards, when the movable rack 112 swings upwards to contact with the vertical plate 4, the vertical plate 4 enables the movable rack 112 to move rightwards, the third spring 113 compresses, the movable rack 112 moves rightwards to drive the first gear 115 to rotate forwards, the first gear 115 rotates forwards to drive the connecting rod 114 to rotate forwards, the connecting rod 114 rotates forwards to drive the baffle 111 to rotate forwards, when the baffle 111 rotates forwards by ninety degrees, the bed plate 7 also swings upwards by ninety degrees, the bed plate 7 stops pulling the bed plate 7, the baffle 111 also stops rotating forwards, the student can lie on the bed plate 7 to rest, and the baffle 111 stops limiting the student. When students get off the bed plate 7 and the fixture block 94 moves inwards to reset, the bed plate 7 is pulled to swing downwards, the bed plate 7 swings downwards to drive the movable rack 112 to swing downwards, the movable rack 112 swings downwards to be separated from the vertical plate 4, the movable rack 112 drives the first gear 115 to rotate leftwards under the action of the third spring 113, and the first gear 115 rotates reversely to drive the baffle 111 to rotate reversely through the connecting rod 114 to reset. Therefore, the falling and the falling of the student from the bed plate 7 in the rest process can be avoided.

Initially, the fourth spring 124 is in a compressed state, when the movable rack 112 moves rightwards, the movable rack 112 also moves rightwards to drive the guide rack 127 to move rightwards, the guide rack 127 moves rightwards to drive the second gear 126 to rotate rightwards, the second gear 126 rotates rightwards to drive the rotating rod 125 to rotate rightwards, the rotating rod 125 rotates rightwards to drive the large reel 123 to rotate rightwards, the large reel 123 rotates rightwards to release the first pull wire 128, the movable sleeve plate 122 continuously moves forwards under the action of the fourth spring 124, when the movable rack 112 stops driving the guide rack 127 to move rightwards, the second gear 126 stops rotating forwards, the movable sleeve plate 122 also stops moving forwards, and a taller student can place feet on the movable sleeve plate 122. When the movable rack 112 moves leftwards to reset, the movable rack 112 drives the guide rack 127 to move leftwards to reset, the guide rack 127 resets to drive the second gear 126 to rotate reversely to reset, so that the large reel 123 rotates reversely to wind the first pull wire 128, the first pull wire 128 winds to drive the movable sleeve plate 122 to move backwards to reset, and the fourth spring 124 is compressed. Therefore, taller students can better lie on the bed plate 7 for rest.

Referring to fig. 1, fig. 2 and fig. 10 still include guide arm 13, contact ring 14, fifth spring 15, movable tube 16 and filter screen 17, guide arm 13 has been placed to the even spaced slidingtype in 8 top circumferences of inlet tube, the rigid coupling has contact ring 14 between all guide arms 13 tops, contact ring 14 bottom circumference and inlet tube 8 evenly spaced between inside be connected with fifth spring 15, fifth spring 15 overlaps on guide arm 13, the movable tube 16 of placing of 8 internal sliding types of inlet tube, movable tube 16 and lid 2 cooperation, movable tube 16 still with contact ring 14 contact cooperation, the inboard lower part circumference rigid coupling of movable tube 16 has filter screen 17.

Still including couple 18, dead lever 19, the guiding axle 20, little reel 21, the second is acted as go-between 22 and volute spiral spring 23, what the inside upside rotary type of riser 4 was connected with the guiding axle 20, both sides circumference all the rigid coupling has little reel 21 around the guiding axle 20, around there being the second to act as go-between 22 on the little reel 21, the second is acted as go-between 22 tail ends and is run through riser 4 rigid coupling and have couple 18, couple 18 and riser 4 contact fit, both sides circumference around the guiding axle 20 respectively with the riser 4 inside around between the both sides have volute spiral spring 23, bed board 7 front and back both sides face lower part all the rigid coupling has dead lever 19, dead lever 19 and couple 18 cooperation.

Initially, fifth spring 15 is compression state, when operating personnel took off lid 2 from inlet tube 8, lid 2 did not carry on spacingly to movable tube 16, because of fifth spring 15's effect, contact ring 14 upwards moves and drives movable tube 16 rebound, and movable tube 16 rebound makes upper portion remove outside inlet tube 8, and operating personnel can pour water into box 1 through inlet tube 8 in, and water contacts with filter screen 17, and filter screen 17 then filters the impurity of aquatic. When having suitable amount of water in the box 1, on returning lid 2 to inlet tube 8, lid 2 drives movable tube 16 downstream, and movable tube 16 downstream drives contact ring 14 downstream and resets, and the compression of fifth spring 15, and then when filtering on the filter screen 17 and having suitable amount of impurity, can take out movable tube 16 from inlet tube 8, pour out the processing with the impurity on the filter screen 17 again. So, can avoid the aquatic to mix a large amount of impurity and block up in with drain pipe 3.

After the bed plate 7 swings ninety degrees upwards, the hook 18 is pulled to move, the hook 18 moves to drive the second stay wire 22 to move, the second stay wire 22 moves to drive the small reel 21 to rotate positively, the small reel 21 rotates positively to drive the guide shaft 20 to rotate positively, the volute spiral spring 23 compresses, the hook 18 can be hung on the fixing rod 19, and the hook 18 is matched with the fixing rod 19 to pull and fix the bed plate 7. When a student gets down from the bed plate 7, the hook 18 is pulled to be separated from the fixing rod 19, the hook 18 is loosened, due to the action of the volute spiral spring 23, the guide shaft 20 rotates reversely to drive the small winding wheel 21 to rotate reversely and reset, the small winding wheel 21 rotates reversely and resets to wind the second pull wire 22, and the second pull wire 22 winds to drive the hook 18 to move and reset. Therefore, the bed plate 7 can be more stable for students to have a rest in a lying mode.

Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made herein without departing from the principles and spirit of the invention as defined by the appended claims.
