Frame 1 is closed, to play the purpose of easy cleaning.
As the inside of Fig. 2 and Fig. 3, side of the steel grating plate 2 far from rotation axis 3 offer the control parallel with rotation axis 3
Slot 22 processed slidably connects control-rod 42 in control flume 22.Steel grating plate 2 offers several and control far from the end face of rotation axis 3
Slot processed 22 is vertical and the locking hole 21 that is connected, offers the locking slot 11 opposite with locking hole 21 on the inner wall of frame 1.Locking
Locking pin 41 is slidably connected in hole 21, locking pin 41 is fixedly linked with control-rod 42.Control-rod 42 is stirred, control-rod 42 is being controlled
Sliding is in slot 22 processed to drive locking pin 41 to slide in locking hole 21.Close steel grating plate 2, locking hole 21 and locking slot 11
Face, locking pin 41 are stretched out out of locking hole 21 in locking slot 11, and steel grating plate 2 is locked.Locking pin 41 shrinks in locking
In hole 21, steel grating plate 2, which may be reversed, to be opened.
Such as Fig. 1 and Fig. 2, the upper surface of steel grating plate 2 offers the link slot 23 parallel with locking hole 21 of bar shaped, even
Control pin 43 is slidably connected in access slot 23.Link slot 23 is stretched out in 43 one end of control pin, and the other end puts in link slot 23 and control
Bar 42 is fixedly linked.Operator stirs control pin 43 to drive control-rod 42 to slide in control flume 22, and then drives lock
Tight pin 41 slides, easy to use.
Such as Fig. 2, locking spring 44 is equipped between control-rod 42 and the bottom of control flume 22.Locking spring 44 is in nature shape
When state, locking hole 21 is stretched out in the end of locking pin 41.Locking spring 44 applies elastic force to control-rod 42, guarantees the lock of locking pin 41
Tight effect prevents the loosening of locking pin 41 from shrinking in locking hole 21.
Such as Fig. 3,1 upper surface of frame offers the sliding groove 12 being obliquely installed in the surface of locking slot 11.Steel grating plate 2
When downwardly turning over, the upper surface of steel grating plate 2 and frame 1 is contradicted, and locking pin 41 and 12 face of sliding groove contradict.Press down on steel
Flase floor 2, the sliding groove 12 being obliquely installed apply thrust to locking pin 41, and locking pin 41 presses locking spring 44 and gradually shrinks in lock
In tieholen 21.
Such as Fig. 2 and Fig. 3, locking hole 21 and the sign pair of locking slot 11, locking pin 41 are inserted into locking slot 11.Locking slot 11 is set as
Taper.The end of the locking slot 11 of cone cell gradually becomes smaller, and locking pin 41 puts in locking slot 11 inner wall until with locking slot 11
It contradicts, locking pin 41, which is fixed, to be shaken, to guarantee the stability of steel grating plate 2, prevented the vibration of steel grating plate 2 from issuing and made an uproar
Sound.It using for a long time, the continuation of locking pin 41 is put in forward after the drawing small of locking pin 41 contradicts with 11 inner wall of locking slot, thus
So that locking pin 41 is contradicted with locking slot 11 always, guarantee the stability of locking pin 41.
Such as Fig. 2 and Fig. 3, the bottom of frame 1 is equipped with the connection to extend internally along 5, when steel grating plate 2 is closed, steel grating plate 2
It is contradicted with connecting along 5, so that locking hole 21 and 11 face of locking slot, facilitate the insertion of locking pin 41.
Such as Fig. 3, several guide grooves 13 being vertically arranged are offered on 1 inner wall of frame, have been slidably connected in guide groove 13
Fin 62.It plays the lower end of fin 62 and is connected with the spring 61 that warps, the lower end for the spring 61 that warps is fixedly linked with connecting along 5.It opens
When steel grating plate 2, locking pin 41 is skidded off out of locking slot 11, warp spring 61 by rise fin 62 to steel grating plate 2 apply to
On thrust so that steel grating plate 2 warps and has a certain degree, convenient for opening.
Such as Fig. 4, the lower surface of steel grating plate 2 is equipped with the slot 24 that warps matched with fin 62.Steel grating plate 2 with warp
When piece 62 is connected, a fin 62, which is slidably connected to, to warp in slot 24.The slot 24 that warps increases the contact of steel grating plate 2 with fin 62
Area improves stability.
Such as Fig. 5, the two sides of guide groove 13 offer the limiting slot 14 being connected with guide groove 13, and the both ends for playing fin 62 are solid
Surely there is the limit plate 63 being slidably connected in limiting slot 14.Fin 62 is played when sliding up and down in guide groove 13, limit plate 63 exists
It is slided up and down in limiting slot 14.Limit plate 63 and limiting slot 14 cooperate, and are defined to fin 62 is played, have prevented fin 62
It is detached from guide groove 13.
Specific implementation process: when opening steel grating plate 2, control pin 43 is stirred, control pin 43 drives lock by control-rod 42
Tight pin 41 slides, and locking pin 41 is shunk in locking hole 21.Warp spring 61 and rise a fin 62 upward push away is applied to steel grating plate 2
Power, steel grating form certain inclination angle, convenient for opening.When closing steel grating plate 2, steel grating is overturn, is pressed down on, locking pin 41
Frame 1 is crossed to put in locking slot 11 to which steel grating plate 2 be locked.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
