The structure of each parts is further described:

A kind of dehydration on-off device of trough mainly is made up of transition cover 1, core assembly 2, knob assembly 3, extension spring assembly 8, can be monomer, binary and many bluk recombinations assembly group.

Fig. 4-the 1st, transition cover sectional structure schematic diagram among Fig. 1; Fig. 4-the 2nd, transition cover plan structure schematic diagram among Fig. 1; Transition cover 1 has adopted external screw thread, circle body 1b, the structure design of external screw thread 1a down, fixedlys connected dexterously by the external screw thread on the outer cover 22 in the internal thread in the circle body and the core assembly 2.Fig. 5-the 1st is the drowning cover of a utility model sectional structure schematic diagram; Fig. 5-the 2nd is the drowning cover of a utility model plan structure schematic diagram; The cover 9 that falls into water can place the cover 1 that falls into water.

Core assembly 2 mainly is made up of parts such as drain gully obstruction 21, outer cover 22, drain gully obstruction push rod 23, push rod spring 24, thimble 25, rotary valve 26, rotary valve base 27, outer cover end caps 28 among Fig. 2, adopt illustrated sequence of positions to put into, be connected on the outer cover 22 with outer cover end cap 28 at last, bottom internal thread 22a in the outer cover 22 assembles in the mode that is press-fitted with outer cover 22, and bottom internal thread 22a can connect in sheath lower contact 86 external screw threads in the extension spring assembly 8.

Knob assembly 3 mainly is made up of connector 31, knob 32, pillar 33, pagoda joint 34 among Fig. 1,2; connector 33 is shaped on external screw thread and can be used for that sealing ring 4 and retainer plate 5 are carried out screw thread with tank 7 and fixedly connected; can insert with pagoda joint 34 on the pillar 33 and be connected; both protect the sheath 85 in the extension spring assembly 8, can strengthen the visuality of outward appearance again.

Extension spring assembly 8 mainly is by knob push rod 81 among Fig. 2, sheath top connection 82, back-moving spring 83, extension spring 84, sheath 85, sheath lower contact 86, transit joint 87 parts such as grade, adopting illustrated sequence of positions to put into is assembled, extension spring 84 is to adopt welding manner and knob push rod 81 to fuse, and can be under the effect of knob 32, in sheath 85, freely make stretching motion, external screw thread by transit joint 87 can connect in sheath top connection 82 internal threads, simultaneously also can with is connected the connection of pagoda joint 34 internal threads, be connected with the internal thread of connector 33 more at last, form appearance effect as figure knob assembly 3.

Transition cover 1 is owing to adopted the circle body 1b design of the formula of soaring, both having played tank fall into water to stop up 21 and is connected with the effective of force transfer mechanism, again because the external diameter of drain gully obstruction 21 is greater than circle body 1b, avoid sewage to flow into core assembly 2 and caused drain gully to stop up the corrosion of metal products such as push rod 23, a pin 25, can also hold the cover 9 that falls into water simultaneously; The structure design of knob assembly 3 and extension spring assembly 8 makes power delivery system obtain effective connection, and has considered the effect of product overall appearance by having used transit joint 87 and pagoda joint 34; The connection that the bottom internal thread 22a of press-fit design is united force coupling medium in the outer cover 22 in the core assembly 2 is more succinct, simultaneously, because of dislocation wedge rib 26a that circumferential five equilibrium is arranged respectively in rotary valve 26, the rotary valve base 27 and wedge tooth 27c design, it is reliable more freely that the gravity that adds thimble 25 presses down the rotation that makes rotary valve 26; Drain gully stops up the 21 low groove 23a that directly put into drain gully obstruction push rod 23 makes assembling excellent in simple.

Operating principle of the present utility model: under the effect that knob 32 presses down, make knob push rod 81 move down back-moving spring 83 pressurizeds thereupon, thereby extension spring 84 is stretched out, withstand on rotary valve base 27 and the rotary valve 26 and move, wedge tooth 27c and wedge rib 26a cooperatively interact drive under, the gravity that adds thimble 25 presses down the rotation that makes rotary valve 26, because outer cover 22 inner chamber hypomeres and rotary valve 26, be shaped on the dislocation outer cover boss 22b of circumferential five equilibrium in the rotary valve base 27 respectively, wedge rib 26a and wedge tooth 27c, make rotary valve 26 rotations, promote simultaneously to move push rod spring 24 pressurizeds in a drain gully obstruction bar 23 and the drain gully obstruction 21, after knob 32 downforce are withdrawn, make knob push rod 81 promote to move on the knob 32 under the effect of back-moving spring 83, and also withdrawal thereupon of extension spring 84, at this moment, rotary valve base 27 stops up push rod 23 with rotary valve 26 and drain gully and drain gully obstruction 21 moves down under the screen resiliences of push rod spring 24 drive, rotary valve base 27 reposition that falls, but because rotary valve 26 has formerly been finished rotation, so, its wedge rib 26a will be seated on the boss upper edge 22c of outer cover 22 can not get back to original position, therefore, drain gully stops up push rod 23 and drain gully obstruction 21 can not be got back to original position too, just locates opening so drain gully stops up 21.In like manner, when pressing knob 32 once more, make rotary valve 26 rotate equally, but after knob 32 downforce are withdrawn, because the foregoing in addition dislocation of the turning effort of rotary valve 26 designs, current rotary valve 26 will move down along the groove 22d in the outer cover 22, make drain gully obstruction push rod 23 and drain gully stop up 21 and get back to original position under the screen resiliences driving of push rod spring 24, so drain gully stops up 21 and just locates closed condition, so can finish drain gully repeatedly and stop up 21 unlatching or closing motion.

Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
