Abstract

A novel well cover assembly comprises a well cover and a well base, wherein the well cover is inlaid inside the upper portion of the well base. The novel well cover assembly is characterized in that two L-shaped clamping grooves which are centrosymmetric are formed in the inner edge of the annular well base, the top end of each clamping groove is communicated with the upper surface of the well base, two convex handles which correspond to the clamping grooves are arranged on the outer edge of the well cover, a lock is installed between each clamping groove of the well base and each convex handle of the well cover, and an unlocking hole of each lock is formed in the well base. The novel well cover assembly has the advantages that the well cover and the well base are provided with the screwing and buckling locks, so that the well cover is capable of being well fixed and prevented from moving or dropping off. The well cover and the well base are mainly made of non-metal and have no economic value, so that the loss phenomenon is greatly reduced. The non-metal materials of the well cover can be coal ash, cost is low, pollution does not exist, thermal insulation performance is good, strength is high and secondary pollution cannot occur. A special unlocking tool is provided, the locks are prevented from being opened randomly by non-staff, and use safety of the well cover is ensured.

Description

The corresponding surface of the outer peripheral face of described well lid and well seat is the taper seat that coincide mutually, is provided with the undergauge step below the taper seat of well seat.

Described well lid is made up of metal ring and the inner nonmetal main body of outer peripheral face.

Upper and lower surface in described nonmetal main body is provided with wire lath, the periphery of wire lath and the welding of the upper and lower end of this metal ring.

On described well lid, be provided with anti-skidding striped.

The open keyhole up/down perforation of described lockset is in the above and below of well seat.

Be provided with the attacker at described well lid.

Described lockset is cylinder lock.

The top of this fork is hinged on the end face of described draw-in groove bottom, and the lower end of this fork tilts in this draw-in groove and is against the bottom surface of draw-in groove, and described open keyhole is located at the top of this fork.

Advantage of the present invention is:

1, utilizes the mutual clamping of draw-in groove of protruding handle and the well seat of well lid, and with lockset locking, can firmly fix well lid, can prevent effectively that well lid from moving and come off and lose;

2, this well lid and well seat mainly adopt nonmetal making, do not have economic worth, significantly reduce and lose phenomenon;

3, the nonmetal main body of well lid can adopt the material based on flyash, and is with low cost, pollution-free, good heat insulating, high strength, good heat insulating, non-secondary pollution;

4, have special-purpose unlocking tool, prevent that the inoperative personnel from arbitrarily opening, ensure the use safety of well lid;

The specific embodiment:

Referring to Fig. 1-Fig. 5, a kind of new pattern manhole cover assembly of the present invention comprises circular well lid 1 and annular well seat 2, and well lid 1 is embedded in the upper port of well seat 2.Interior edge at the well seat 2 of annular is provided with centrosymmetric two L shaped draw-in grooves 21, the top perforation of the top of this draw-in groove 21 and well seat 2.Be provided with two protruding handles 11 corresponding with this draw-in groove 21 in the outer of this well lid 1.Between the protruding handle 11 of the draw-in groove 21 of this well seat 2 and well lid 1, lockset 3 is housed, the open keyhole 22 of this lockset 3 be located at well seat 2 above.Open keyhole 22 preferably runs through the top and bottom of well seat 2, avoids open keyhole 22 blocked like this, is convenient to cleaning and mediation open keyhole 22.Lockset 3 adopts simple cylinder lock to get final product, and after the protruding handle 11 of well lid 1 turned to draw-in groove 21 bottoms, the dead bolt of lockset 3 ejected protruding handle 11 is blocked, and has only with key and could open lockset 3, and protruding handle 11 is screwed out, and avoids well lid 1 to lose.

The corresponding surface of the outer peripheral face of described well lid 1 and well seat 2 is the taper seat that coincide mutually, is provided with undergauge step 23 below the taper seat of well seat 2, is support and the location of well lid 1.Be provided with attacker 12 at described well lid 1, be convenient to install and take out well lid 1.

Anti-skidding striped (not shown) can be arranged on described well lid 1.

One embodiment of the present invention are: described well lid 1 is made up of metal (iron) ring and the inner nonmetal main body of outer peripheral face.Can be provided with the ribs (not shown) to lower convexity below the well lid of this structure.Well lid also can all be made by nonmetals (as resin, steel concrete, mixture of fly ash etc.).

Also can be provided with wire lath on the upper and lower surface of described nonmetal main body, the periphery of wire lath and the welding of the upper and lower end of this metal ring.Needn't establish ribs below the well lid of this structure.

Equally, can be provided with metal inner lining at the inner peripheral surface of described well seat 2, remainder is that nonmetals are made.Well seat 2 also can all be made by nonmetals (as resin, steel concrete, mixture of fly ash etc.).

The nonmetal main body of well lid 1 of the present invention and the nonmetals of well seat 2 can adopt discarded flyash with flyash, also iron tailings after available gangue of pulverizing or the magnetic separation of pulverizing, grind size is 200-650 orders, replace flyash, the additive that adds the sticking intensity of raising tension strength of fire retardant, fusion agent, resin acid, paraffin, special secret prescription, the main material prescription is (meter by weight): flyash 65-75, fusion agent 2-3, resin acid 10-20, fire retardant 2-3, other additives 9%-11%.Have in the prior art and adopt above-mentioned material as the application of tubing.

The using method of an embodiment is in the present invention: during installation, two protruding handles 11 of well lid 1 are inserted from draw-in groove 21 upper ends of well seat 2, turn to draw-in groove 21 bottoms (being inner terminal) then, the dead bolt of lockset 3 ejects protruding handle 11 is blocked, and finishes installation.When needs take out well lid 1, insert open keyhole 22 with key and open lockset 3(with the dead bolt retraction), protruding handle 11 is screwed out.

Lockset 3 of the present invention can also be structure shown in Figure 6, fork 4 is as lockset, the top of this fork 4 is hinged on the end face of described L shaped draw-in groove 21 bottoms, and the lower end of fork 4 tilts in the draw-in groove 21 and is against the bottom surface of draw-in groove 21, and described open keyhole 22 is located at the top of this fork 4.During use, two protruding handles 11 of well lid 1 are inserted from draw-in groove 21 upper ends of well seat 2, turn to draw-in groove 21 bottoms (being inner terminal) then, the lower end of fork 4 is upwards swing before this, and after protruding handle 11 put in place, the lower end of fork 4 fell, and blocked protruding handle 11.When need taking out well lid 1, the instrument that has a crotch with front end is passed down through open keyhole 22 and hooks fork 4 and upwards be pulled to level, and this moment namely can be with well lid 1 revolution, until taking out well lid 1.
