Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1 to Fig. 4, the back-buckling type runner inspection eye waterproof cover providing in figure, comprises runner top board 100 and cover board body 300, on runner top board 100, offers inspection eye.In Fig. 1, provide the structure of an inspection eye 200.Check that hole 200 and runner top board 100 are connected as a single entity, cast in situs.
The size of inspection eye bottom 220 is greater than the size on inspection eye top 210, and hole end face 221 formations of inspection eye bottom 220 seal with the upper surface 330 of cover plate plate body 300 sealing surface contacting.On the hole of inspection eye bottom 220 end face 221, around surrounding reserved weather strip groove 221a in the time that runner top board 100 is built on inspection eye top 210, when installation, in weather strip groove 221a, be placed with rubber water-proof bar 400,400 one-tenth square frame-shapeds of rubber water-proof bar are arranged in the surrounding on inspection eye top 210.
In the time of cast runner top board 100, be embedded with ironware on one side of the hole of inspection eye bottom 220 end face 221 in addition, in order to weld hinged-support 500, its excess-three limit is reserved with crochet groove 221b.Be embedded with symmetrically ironware at the edge, hole on runner top board 100 contiguous inspection eye tops 210, in order to be symmetrically welded two lock ingots 600 simultaneously.
Whole cover board body 300 is also square, and its size should be greater than the size on inspection eye top 210 but be less than the size of inspection eye bottom 220, and cover board body 300 just can be arranged in the hole of inspection eye bottom 220 like this.
On the edge on one side of cover board body 300, be welded with hinge 310, after hinge 310 is hinged with hinged-support 500, whole cover board body 300 just can be hinged on the hole end face 221 of inspection eye bottom 220.On its excess-three limit of cover board body 300, be provided with and upwards dig and the crochet 320 suitable with corresponding crochet groove 221b in addition.Also have corresponding to rubber water-proof bar 400, on the upper surface 330 of cover board body 300, be embedded with stainless steel steel bar 331, stainless steel steel bar 331 also surrounds a square frame-shaped, coordinates with rubber water-proof bar 400.In order to improve sealing effectiveness, the 331 surface finish processing of stainless steel steel bar.
On the upper surface 330 of cover board body 300, be embedded with four door upper lift rings 332, four door upper lift rings 332 lay respectively at four square vertex positions, be connected with a chain 700 with two door upper lift rings 332 of lock ingot 600 homonymies, the two ends of chain 700 are fixedly connected with a door upper lift ring 332 respectively, are fixed with a clasp 710 in the centre position of chain 700.Lock ingot 600, door upper lift ring 332, chain 700 and clasp 710 all can adopt existing product.
Operating procedure and the method for back-buckling type runner inspection eye waterproof cover of the present utility model are:
(1) cover board body 300 is closed step and method
Artificial two chains 700 that extract also upwards lift, clasp 710 on chain 700 is buckled on the lock spindle blade of lock ingot 600, tumble lock spindle blade is locked in clasp 710 on ingot 600, at this moment cover board body 300 tightly left-hand thread on the hole of inspection eye bottom 220 end face 221, stainless steel steel bar 331 on cover board body 300 upper surfaces 330 is pressed on rubber water-proof bar 400, the crochet 320 on cover board body 300 3 limits is inserted in crochet groove 221b, now because cover board body 300 is subject to one pulling force upwards, in the time there is no water pressure, in sealing state.In the time that runner is full of water, under effect of water pressure, pressure is larger, and hermetic seal effect is better.
(2) cover board body 300 opening steps and method
In the time that needs overhaul runner or water pump, first drain the water body in runner, then open lock ingot 600, take off clasp 710, put down chain 700, cover board body 300 under deadweight around it with the upset downwards of the pin joint of hinged-support 500 and open, or open cover board body 300 to 300 1 downward thrusts of cover board body a little.Now cover board body 300 1 side mountings are on hinged seat 500, and maintainer can enter in runner and overhaul from inspection eye 200.After maintenance, can according to above-mentioned steps and method again by cover board body 300 tightly left-hand thread on the hole of inspection eye bottom 220 end face 221.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
