Description

Two antitheft catch-basin well lids

A kind of pair of Theft-proof rain-drainage well cover belongs to the improvement of urban rainwater well.

The well lid of the catch-basin of town and country use at present adopts mostly and directly well lid is placed on the well seat seam, and this well lid is placed and opened conveniently.But the stolen phenomenon of well lid is serious in recent years, and the well head that we opens has been made many traffic accidents.Therefore many innovation and creation about anti-stealing manhole cover are arisen at the historic moment.But what have is too high impracticable because of cost, have again because complex structure use inconvenient and not the unit of being used adopt.

The purpose of this utility model provide a kind of simple in structure, make, use easily, the reliably two antitheft catch-basin well lids of theftproof performance.

The utility model scheme is achieved in that respectively there is at least one lower margin screw any both sides of well seat of its catch-basin, are fixed on the well seat on the well head basis with stone bolt; Well seat both side ends has pin hole; A comb side and well seat pin hole corresponding section of well also has pin hole, and well is combed and the well seat is an one with the pivot pin riveted joint.

The two Theft-proof rain-drainage well covers of the utility model are simple in structure, easy to manufacture, easy to use, and theftproof performance is reliable.Because well lid and well seat rivet or weld with pivot pin extremely in a side, and the well seat is connected as a single entity with cement casting or alternate manner with stone bolt and well head basis, also rivets after the well seat installs or welds extremely on the stone bolt, can prevent effectively that the well seat is stolen.In addition, because the utility model well lid and the special syndeton of well seat make the well lid on the road be difficult for by the automobile pressure backfin or dislocation.

The utility model has following accompanying drawing.

The antitheft well of Fig. 1 the utility model catch-basin is combed, well holder structure schematic diagram.

Fig. 2 is the two Theft-proof rain-drainage well covers of the utility model, well seat and basic scheme of installation.

How further specify the utility model below in conjunction with accompanying drawing realizes.

The utility model catch-basin is made up of well comb (1), well seat (2), and well comb (1) has pin hole in a side, and well seat (2) has pin hole in upper end, opposite position both sides, and any two middle side parts of well seat (2) respectively have at least one lower margin screw.During installation, earlier well comb (1) is had a corresponding side of a side fill-in well seat (2) of pin hole, well comb (1) and the pin hole of well seat (2) in penetrate that an end rivets or the pivot pin of round end (4), the pivot pin other end is rivetted or welds extremely, pivot pin (4) well seat (2) with pin hole be interference fit, pivot pin (4) is a matched in clearance with the pin hole of well lid (1), and well lid (1) can rotate around pivot pin (4); If transform old well, can on old friend's well mouth basis, get out screw, in the hole, pour into the ordinary salt sour water mud that stirs, after being pressed into stone bolt (3) and waiting to solidify the well that assembles is combed (1) and well seat (2) is installed on the basis, stone bolt (3) and nut are tightened and bolt is rivetted or welds extremely.Well comb (1), well seat (2) are connected as a single entity with the basis like this, can prevent effectively that well from combing (1) and well seat (2) is stolen.During use, hook the comb breach of (1) and the corresponding side of pivot pin (4) of well, upwards prize earlier with cleek or crowbar, make well lid (1) activity after, upwards draw just and can open well lid.Putting down well lid (1) with cleek after construction finishes gets final product.

If the two anti-stealing manhole covers of the utility model are used for the assembling of new well, can when building well, on the well head basis, add the built-in fitting stone bolt, all the other installations are identical with preceding method.

Claims (1)

1, a kind of pair of Theft-proof rain-drainage well cover, well seat, well comb by catch-basin are formed, it is characterized in that: the square well of its catch-basin side end broad ways of combing has pin hole, and upper end, well seat broad ways both sides also has pin hole with well comb corresponding section, and well is combed and the well seat is an one with the pivot pin riveted joint; Any two middle side parts of well seat respectively have at least one lower margin screw, and the well seat is connected as a single entity by stone bolt and basis.
