Description
The utility model belongs to a kind of underground pipe well well lid commonly used.
At present, underground pipe well well lid is lost phenomenon and is often taken place.Existing anti-stealing manhole cover generally is between well lid and well seat hinge to be set, and during flip, needs well lid is uprightly overturn, and it is gruelling that the workman feels.The well lid that also useful nonmetals are made, insufficient strength is damaged easily.
The purpose of this utility model provides a kind of straight-bar movable balls formula anti-stealing manhole cover, makes its structure more reasonable, open laborsaving, can be not robbed or burgled.
The technical solution of the utility model is such:
Straight-bar movable balls formula anti-stealing manhole cover, comprise round manhole cover, manhole cover base, connector, it is characterized in that: be provided with the connector of a convex or spill at the well lid edge, connector is provided with a colored shape connecting hole, the pair of holes lobe of symmetry is penetrating, and the pair of holes lobe is not penetrating in addition; The manhole cover base edge corresponding with the well lid connector is provided with and protrudes or recessed support shoulder, supports on the shoulder connecting hole is set; The spherical connecting pin of straight-bar bottom is spherical in shape, and there is the double tail of symmetry the upper end, and it penetrates in the connecting hole of well lid and manhole cover base, squeezes in the penetrating hole lobe fixing with fixed wedge.
For making the bulb flexible swinging of connecting pin, the connecting hole that manhole cover base supports on the shoulder is designed to slotted hole, and top edge is inclined upwardly, and lower limb is camber line shape.
During installation, earlier manhole cover base is placed on the well, fix with concrete.Again well lid is placed on well seat one side, the connecting hole on manhole cover base and the well lid is aimed at, straight-bar movable balls formula connecting pin is penetrated from below, and, it is shelved on the lobe of non-penetrating hole, fixed wedge is squeezed in the two penetrating holes then two empennage half-twists.
When needs are taken off the lid maintenance, catch on well lid with special-purpose shadoof and carry the hole, well lid is upwards slightly carried, at this moment connecting pin promotes with well lid, and the connecting pin bulb is stuck, well lid can be in the certain angle scope wallowing motion, be the center of circle with the connecting hole with well lid then, the plane is revolved and is pulled to outside the well.Work finishes, and again well lid is retracted original position.
The utility model has the advantages that and take off Gai Buxu upset that open laborsavingly, connecting pin is reasonable in design, and is simple in structure, is difficult for losing; Adopt cast iron materials, antiseptic property is good.Be applicable to the anti-stealing manhole cover that underground pipe well is commonly used.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is the shape schematic diagram of spirogyrate connector well lid.
Fig. 2 is the structural representation of the manhole cover base that matches with Fig. 1.
Fig. 3 is the scheme of installation of Figure 1A section.
Fig. 4 is the scheme of installation of Figure 1B section.
Embodiment one, male type straight-bar movable balls formula anti-stealing manhole cover have two to carry hole 11 on the round manhole cover, be provided with a convex connector 2 at well lid 1 edge, and connector 2 is provided with a colored shape connecting hole 3, and the pair of holes lobe 4 of symmetry is penetrating, and pair of holes lobe 5 is not penetrating in addition; Manhole cover base 12 edges corresponding with the well lid connector are provided with the support shoulder 6 of protrusion, support to be provided with on the shoulder to connect slotted hole 7; The movable spherical connecting pin of straight-bar 8 bottoms are spherical in shape 9, and there is the double tail 10 of symmetry the upper end, and it penetrates in the connecting hole of well lid and manhole cover base, squeezes in the penetrating hole lobe with fixed wedge 13; Manhole cover base supports the connecting hole top edge 14 upwards 45 ° of inclinations on the shoulder, and lower limb 15 is camber line shape.
Embodiment two, inner concave shape straight-bar movable balls formula anti-stealing manhole cover, in the recessed round manhole cover of connector on the well lid, manhole cover base supports in the also recessed well of shoulder, connecting hole on it is corresponding with the well lid connecting hole, the connected mode of straight-bar movable balls formula connecting pin is identical with embodiment, and two kinds of forms can be selected as required.
