Description

Contiuum type inspection shaft

Technical field

This utility model relates to a kind of inspection well cover, especially a kind of Contiuum type inspection shaft.

Background technology

Along with the progress of modernization science and technology civilization, and the sharply increasing of population, the sewer in city is built more and more extensive, and it is more and more important that the safety of the antitheft and road pedestrian vehicle of inspection well cover shows.And existing well lid open when road maintenance detects latter be lid be individually placed roadside, be there is potential safety hazard in Pedestrians and vehicles；Daily lid is easily because being lost by impacts such as sewer stream, and itself is the most easily stolen, lacks lid and causes Pedestrians and vehicles easily to drop in inspection shaft；Lid often removes with base and puts back to, and frictional force is big, decreases the shelf life of well lid, adds social cost；And another kind inspection shaft is usually base and is connected with lid axle by base side wall through hole, but through hole makes to affect base side wall stress to be concentrated, and comprcssive strength is inadequate, and easy stress ruptures, and open lid and be typically up to 90 degree, therefore well lid existence is extremely improved demand.

Summary of the invention

For solving the problems referred to above, this utility model provides a kind of Contiuum type inspection shaft.

The technical solution of the utility model: Contiuum type inspection shaft, the lid of base it is connected to including base and axle, it is characterized in that: described lid is discoid and is arranged with a pair outward extending first extension block and the second extension block, lid at the second extension block is provided with the locking device for pinning lid and base, and the lid upper surface that this locking device is corresponding is provided with lockhole；Base lower limb is provided with epitaxial layer, and described epitaxial layer is arranged with positioning through hole, and described base is provided with first groove corresponding with lid and the second groove；Described first bottom portion of groove is provided with the keel of a corresponding first extension block, and the first recess sidewall of these keel both sides has inward recess, and this inward recess connects with base inner wall.

Lid is movably connected with the base when avoiding conventional lid maintenance and is arbitrarily abandoned, loses, and reduces loss；It is provided with the first extension block and the second extension block at lid and base engagement, prevents in use lid from rotating displacement, reduce the abrasion with base, increase service life；The height of keel is padded first extension block, the adjustment of height realizes angle adjustment so that lid relatively can be opened certain angle, preferably open angle can reach 120 degree with base；And use now base the first groove inner wall to offer inward recess to realize axle connection disassembling, it is not necessary to get through hole on base, improve the compressive resistance of base, reduce stress tender spots；Directly can extract the axle of connection during lid breakage below base out, then change lid, lid can not directly be taken apart from base by outside, coordinates lock device, the most antitheft.

Further, the sidewall symmetry of described base is provided with projection.Increase the stress intensity of the sidewall of base, also allow for being easy to when craft or employing instrument dismounting base have impetus.

Further, the outer of described base is provided with positioning through hole, and the bottom surface of base is provided with detent.The design of the detent of positioning through hole and base end face on base, makes the good contacts such as base and road cement, increases firmness.

Further, described locking device is tongue type lockset, and described base lower surface has the arc locked groove of corresponding tongue type lockset.Tongue type lockset, needs corresponding special key to open, prevents from arbitrarily opening, improve security performance.

Further, the upper surface of described lid is additionally provided with circular protrusions, and the height of described circular protrusions presents arrangement from high to low from lid central point to cover edge, and the outer of the upper surface of lid is provided with strip projected parts.The employing of lid upper surface is such is designed with draining profit sand beneficially in time, reduces hydrops in the middle part of lid.

Further, rubber bump protection ring it is provided with between described lid and base.The setting of rubber bump protection ring, can improve the flatness between lid and base, reduces noise when car crosses, plays shockproof noise control effect.

Further, described positioning through hole is preferably ellipse.

Further, described lid and base open angle are 0 °-120 °

Improvement of the present utility model: 1. lid and bottom seat Contiuum type design, prevents lid from arbitrarily abandoning when overhauling, losing；Lid can open with 120 degree, opens conveniently, makees security warning when opening.2. with locking device, it is furnished with tongue type lockset, needs special key to open, prevent from arbitrarily opening, improve security performance.3. with shockproof noise-reducing design, base built-in rubber bump protection ring, can improve the flatness of well lid, reduce noise when car crosses.4. lid replaceability design, lid one end uses bolt axle to be connected with base, directly can extract axle from base out when lid breakage and change.5. lid is with Position Design, the i.e. first projection and the second projection and the first groove and the second groove fit on base, prevents lid in using installation from rotating displacement, reduces the abrasion with base, increase service life.6. base Position Design, hole, base edge multiple location, base back surface also has detent, makes base contact very well with cement etc., increases firmness.7. the height of the circular protrusions in lid front is seen as a camber line from high to low, edge decorative pattern opening Design, the most non-touching strip projected parts from center to edge sides, and timely draining profit is husky.

The beneficial effects of the utility model: using the design lid and base to open can be to 120 °, even more wide-angle, with ground level at an angle in the visual range of people, rather than tradition is placed on roadside, during maintenance, pedestrian and vehicle are risen certain warning function, reduces the stolen risk of well lid, improve safety coefficient, improve the service life of well lid to a certain extent, decrease the social cost of entirety.
