The specific embodiment

For ease of the further purpose means of understanding the present invention, attached now with preferred embodiment figure detailed description as back:

As Fig. 1 finding, place the handgrip 12 on the first position lid 10 to be installed in 11 li of cam cases, the aperture of handgrip 12 upper ends is hung a crotch and is up drawn, and then the cam gear 13 that forms because of handgrip 12 lower ends is closed, and prevents to enter rainwater, can not get rusty.Triangular cam device 13 erects, the cam lock dead axle 14 that then is connected on the same line drops to the well lid edge, and lid 10 is opened, and on the contrary handgrip 12 being evened up then, cam gear 13 declines tangle, cam lock dead axle 14 by on push away lid 10 activities that do not allow on the edge that contact, therefore be closed.

Being seen handgrip 12 is the appearance that erect in Fig. 1, and the appearance when falling can be seen in Figure 11, when cam lock dead axle 14 erects, can see because of cam gear 13 cam lock dead axles 14 and moving down, when handgrip 12 is set level, move, this shows that it is to constitute with the principle that moves up and down because of on 13 of the cam gears.

Divide the well lid at 4 positions to be combined into one when whole, the appearance that forms the cross section embodies at Figure 11, and outer tube 30 is buried underground, how with available fixed flange 33 picture side angles welding, or tightly makes its inertia with screw hole 34 bolts, anyway should firmly be installed on deep under ground.The outer tube stratum 31 that regulates height is divided into 6 five equilibriums too, and one of this five equilibrium is striden one and formed stratum, is the reason that its length of explanation will fully reach height when constructing again when cultivating oneself according to a religious doctrine.

Fig. 2 is that the first position lid 10 is opened, the state that handgrip 12 erects, Fig. 3 is pipe 20 structures in second position, cam lock dead axle 14 length that are connected in handgrip 12 can lock, can solve easily when interior pipe went wrong in 20 o'clock for cam lock dead axle 14 injects thus, reserve slit 15 on interior pipe 20 tops cam lock dead axle 14 is inserted easily.For wall externally form in pipe stratum 21 circumference enclosed be divided into 6 five equilibriums, pipe stratum 21 and interior pipe stratum projection 22 can be rotated and be regulated height in arrangement of span.The face of entrance hall appearance is reserved in interior pipe 20 upper ends, forms rubber pad ring recess 23, fills up to prevent into water with rubber pad (Packing), can not infiltrate dust and water at ordinary times, and rainy weather also needn't be worried can immersion.

Fig. 5 is the form of the 3rd position outer tube 30, be fixed on flange 33 on the ground and be mounted to circle, when outer tube stratum 31 reaches the 900mm left and right sides together with outer tube stratum projection 32 inwards, can fully use, reserve screw hole 34 on the flange 33 and help to fix, it is fixed that length should be come according to the requirement of construction office.

Fig. 7 is that Fig. 8 is the situation that shell is divided into two assemblings for the constitutional diagram of the reason that the necessary counterpart of outer tube 30 shells is described.

Fig. 9 is the explanation of relevant lid 10 and the part key diagram of relevant cam gear 13 with Figure 10.

Therefore; put shell 40 and be the stratum between the pipe and outer tube and the necessary accessory of projection in the protection; enter impurity for preventing between the

stratum

21,31 when moving on the interior pipe 20; the 4th position shell 40 with two compositions entangles; be bolted with shell bolt cover 41 and enter foreign substances between two stratum, 21,31 and two

adjustings projection

22,32 between pipe 20 and the outer tube 30 in can preventing, this is the measure that prevents that

stratum

21,31 and

projection

22,32 are not impaired.

So, having only 3 parts in 6 five equilibriums is to be made of stratum and projection, it is staggered between outer tube 30 and the interior pipe 20 though lid 10 and interior pipe 20 connect airtight, might enter foreign substances between stratum, form a well lid so need put shell 40 in addition, this just is 4 part manhole covers, the characteristics of this structure that Here it is.

The invention effect

Only need be provided with once and need not construct again according to the invention described above, can regulate height rapidly, realize good producing on the engineering, can install rapidly when being arranged at the cement closed conduit, highly regulating 4 part manhole covers correctly regulates as being fit to inner and outer pipe, next cover the well lid lid, fasten with cam gear, in conjunction with interior pipe top fill in prevent to shake, the rubber pad of noise is promptly sealed.

When the handgrip of cam gear well lid lid locking device vertically erects, moved down by the effect lock shaft of cam gear to bite the lid lock to be closed, when handgrip was set level with 90 degree, lock shaft was fixed to the lower end, becomes the outstanding well lid that closes lid.

Enter the phenomenon of foreign substances between shell protection outer tube and the interior pipe, the flange of outside pipe and screw hole be well lid fixedly, and fixing outer tube only, so interior pipe moves up and down and makes highly concordantly with the road surface, not overslaugh vehicle prevents that also the road surface is hit.

So, according to 4 day the order permutation manhole is set in proper order, no matter any vibrations or upheaval can not shaken yet, and have the road rebuilding or when constructing again, remove advantage that moment can pass through at once and the effect of not bringing the time obstacle.
