Abstract

The utility disclose a safety manhole cover comprising cover, central spindle, shaft base, buffer alarming rubber ring, protective alarming net and screw, and taking advantage of thermal expansion and cold shrinkage principle for combining well cover and base so as to avoid theft and damage. The buffer alarming rubber ring is designed for reducing direct impact of well cover and base, thereby prolonging service life muting the environment; and has alarming function when well cover is lost or damaged. The protective alarming net can alarm pedestrian and prevents pedestrian from falling when well cover is lost or damaged. The utility is simply structured, easily processed, theftproof, damage-free, environment-friendly, safe and reliable.

Description

Safety well cover

Technical field

The utility model relates to well lid, be specifically related to a kind of Safety well cover, belong to International Classification of Patents E02D29/14 technical field.

Background technology

Well lid has certain history on world's municipal administration history, but is often easily ignored by people in the life that people have much to do, when it is lost or damages, and the importance that just someone will watch attentively it.Along with the metal price in metal market, the world improves constantly, the metal price that reclaims Steel Wire Products Industry also improves constantly, the well lid idea that the repayment of high profit impels some lawless person to play to be related to public safety.Well lid is stolen to have become a global difficult problem soon, and losing that well lid is a large amount of not only causes enormous economic loss, and brings huge threat for pedestrian and vehicle.Owing to the well lid that opens wide for the needs or the stolen reason of draining fails in time to add a cover, under the situation that does not have caution and protection, well lid is just as a big mouthful of safety that is threatening people's life of biting the people.

Summary of the invention

The purpose of this utility model is to provide a kind of physical characteristic that makes full use of material, reaches antitheft, anti-and pounds and well lid that environmental protection is inexpensive, safe and reliable.

The purpose of this utility model is achieved through the following technical solutions.

A kind of Safety well cover, partly form by well lid, axle core, well seat, buffering caution glue ring, protection caution net and screw etc., well lid, axle core, well seat are combined into movable overall, the axle core is installed on well lid or the well seat by the physical method that expands with heat and contract with cold, tightly be stained with buffering caution glue ring in the well seat, protection caution net passes several installing holes in the well seat, tightly is fixed in the well seat with screw.

The manufacturing materials of buffering caution glue ring and protection caution net can be made or fiber, synthetic resin are made by the junked tire of the cord fabric thread that is difficult to recycle, steel wire part.

Buffering caution glue ring is coated with noctilucence or reflecting coating with the surface of protection caution net.

Safety well cover of the present utility model has made full use of the physical characteristic of material, antitheft, anti-pound and environmental protection inexpensive, safe and reliable.The design of buffering caution glue ring has reduced the direct impact of well lid and well seat, has prolonged application life, and has realized not having and make an uproar, and plays important warning function when well lid damages or loses.When well lid damaged or loses, protection caution net can be made caution and the protection that prevents to fall to traffic.

Description of drawings

Accompanying drawing is the overall structure schematic diagram of the utility model Safety well cover.

Among the figure: 1, well lid, 2, the axle core, 3, the well seat, 4, buffering caution glue ring, 5, protection caution net, 6, screw.

The specific embodiment

Referring to accompanying drawing, the utility model is by well lid 1, axle core 2, well seat 3, buffering caution glue ring 4, protection caution net 5, and screw 6 is formed.Its unusual part be its by well lid 1 or well seat 3 the physical method installation shaft core 2 to expand with heat and contract with cold, be combined into well lid 1, axle core 2, well seat 3 movable overall.Buffering caution glue ring 4 tightly sticks in the well seat 3, and protection caution net 5 passes the installing hole in the well seat 3, tightly is fixed in the well seat with screw 6.

Well lid 1 can be with multiple material manufacturing, fiber, synthetic resin, steel, ductile iron; Axle core 2 can be made with alloy, steel, and well seat 3 can be a manufactured materials with steel, ductile iron.

Be that embodiment further specifies the utility model below with the steel: well lid 1 is the integral body that is connected into an activity with axle core 2 with well seat 3.The installing hole of heating well lid 1 partly utilizes principle of expanding with heat and contracting with cold installation shaft core 2, impels well lid 1 to compact to combine with axle core 2 and combines together, and axle core 2 rotates integral body flexibly with 3 one-tenth of well seats and reaches antitheft, the anti-effect of pounding.Buffering caution glue ring 4 is made by the waste and old peptide of taking turns of the cord fabric thread that is difficult to recycle, steel wire part with protection caution net 5, not only reliably but also environmental protection.Buffering caution glue ring 4 and protection caution net 5 surface spraying noctilucence or reflecting coatings, buffering caution glue ring 4 tightly sticks in the well seat 3, play the direct impact that reduces well lid and well seat and increase the service life and realizes noiseless, when well lid damages or loses, cushion and warn glue ring 4 and play important warning function.Protection caution net 5 passes the installing hole in the well seat 3, tightly is fixed in the well seat 3 with screw 6, and protection caution net 5 acts on when well lid damages or loses vehicle and pedestrian are made caution and the protection that prevents to fall.
