Description of drawings

The invention will be further described below in conjunction with accompanying drawing embodiment:

Fig. 1 is embodiment of the present invention longitudinal section, and this figure has showed the sealing state of whole drainage mechanism;

Fig. 2 is also embodiment of the present invention longitudinal section, has showed hull-borne;

Fig. 3 is this embodiment assembly explosive view.

The specific embodiment

As Fig. 1, embodiment of the present invention longitudinal section, this figure have been showed the sealing state of whole drainage mechanism; From the formation of this figure, whole mechanism is positioned at the bottom sides position of water tank 200; Have a drain hole 201 in water tank 200 side herein, these drain hole 201 normal direction are horizontal; Draining core 100 is axial by it, is guide rod 102, seal disc 101 and shell fragment 103 from left to right in figure, also has a boss 104 on shell fragment 103;

Outside drain hole 201, fix a gland 300 with screw 700, this gland 300 is pressed on drain hole 201 by a sealing mat 400; And this gland 300 has a through hole, and is corresponding with drain hole 201.

The shell fragment 103 of draining core 100 is connected in the through hole and drain hole 201 of gland 300; Guide rod 102 socket one back-moving springs 600 and activity simultaneously is matched with in bar cover 202, and under this structure, guide rod 102 horizontally slips with respect to bar cover 202.The distance of bar cover 202 and sealing mat 400 is less than the length of guide rod 102, and so, when seal disc 101 fitted in sealing mat 400, guide rod 102 still kept being matched with in bar cover 202.And seal disc 101 and sealing mat 400 are parallel to each other, and make the water in water tank 200 both fit tightly Shi Buhui from drain hole 201 omissions.As showing in figure, under the acting in conjunction of the pressure of water tank 200 interior water bodys and back-moving spring 600, seal disc 101 fits tightly in sealing mat 400, water state till this.

Fig. 2 is also embodiment of the present invention longitudinal section, has showed hull-borne; On the basis of Fig. 1, promote draining core 100 from the outside from right-to-left, until the boss on shell fragment 103 is crossed the buckle 301 on gland 300, because boss 104 end faces have lower oblique surface by guide rod 102 1 sides, simultaneously corresponding buckle 301 bottoms have upper oblique surface by water tank 200 outsides, and boss 104 can be crossed buckle 301 easily.

After boss 104 is crossed buckle 301, seal disc 101 is already away from sealing mat 400, be revocable active force to draining core 100 this moment, so, boss 104 is subject to the spacing of buckle 301, makes draining core 100 under back-moving spring 600 effect of stress, keep this state, thereby the water from water tank 200 can be from drain hole 201, and the through hole of the sealing mat 400 of flowing through, gland 300 is finally discharged from the drainage trough 302 that gland sets firmly.Be in the position of whole water tank 200 lowest water levels due to drainage trough 302, so under the prerequisite that drain hole 201 is as above all opened, current are discharged from drainage trough 302, complete the operation of Quick drainage; To such an extent as to it is to prevent that outside improper impact from arbitrarily striking 100 generations of draining core and misprinting the water operation that drainage trough 302 also has a benefit.

Drain operation is complete, must reset to draining core 100, makes water tank 200 again return to the sealing state to recover normal use.On the basis of Fig. 2, press...with one's finger and press shell fragment 103, make boss 104 break away from the spacing of buckle 301, thereby under back-moving spring 600 effect of stress, whole draining core 100 is motion from left to right immediately, until seal disc 101 is close to sealing mat 400 again, closed the drain hole of water tank 200, namely complete the sealing operation.

In conjunction with Fig. 3, need to prove, this sealing operation has used the guard ring 105 on a slide plane 203 and draining core 100; Slide plane 203 direct forming are in the bottom of water tank 200; And guard ring 105 forms in 100, two, draining core and is fixed in seal disc 101, and surrounds the outer peripheral edges of shell fragment 103; Free end both sides at shell fragment 103 also have arc-shaped recess.this both is very easy to operation slide plane 203 and guard ring 105: when finger presses shell fragment 103, perception shell fragment 103 needs the degree of deformation at an easy rate under 105 depression sense of touch on guard ring, to such an extent as to the excessive shell fragment 103 of also needn't worrying simultaneously to exert oneself damages, on the other hand, in conjunction with the fixed point of draining core 100 in Fig. 2 as can be known, and even when finger presses shell fragment 103 guard ring 105, draining core 100 will produce one by 102 pairs of bar covers 202 of guide rod and upward pressure, produce a downward pressure by 101 pairs of slide planes of seal disc 203 simultaneously, when setting the mutually tactile part of slide plane 203 with seal disc, when the projection sensing with shell fragment 103 deformation on seal disc 101 is consistent, this balance between two forces, can not make the state of draining core 100 abnormals when making finger presses shell fragment 103, press more reliable, therefore make operation more convenient, by simple unidirectional pressing, can make draining core 100 complete the sealing state, more embodied the quick operating advantage of whole mechanism.

In Fig. 3 explosive view as can be known, whole mechanism, only for a drain hole 201 and several screw hole are provided, the peripheral hardware annex is sealing mat 400, back-moving spring 600, draining core 100, gland 300 and three screws 700 simultaneously to the processing of water tank 200.Install very easyly and reliable, maintenance cost and man-hour are all lower.

The above, only for preferred embodiment of the present invention, therefore can not limit according to this scope of the invention process, the equivalence of namely doing according to the scope of the claims of the present invention and description changes and modifies, and all should still belong in the scope that the present invention contains.
