Abstract

The utility model discloses a novel anti-theft underground pipe line manhole cover, including a base 1 and a catch basin cover 2, wherein the catch basin cover 2 has two parts matching with the surface shape of the joint; a switch 5 is arranged at the middle of the catch basin cover 2, and the catch basin cover 2 is in flexible connection with the base 1 by the bond 4. The beneficial effect of the utility model is: due to the semi-circle open connecting structure, for the thief, if he has no technical instrument, it is difficult to open, thereby adding the stealing difficulty and prolongs the stealing time. So, the catch basin cover can effectively prevent the stealing, which powerfully ensure the safety of the people. The novel anti-theft underground pipe line manhole cover adopts the circle semi-opening connecting structure, which uses a little cast iron as the frame, mixing with cement and other materials as the fillers, and has low returned value to make the stealer feel profitless.

Description

The novel underground pipeline inspection shaft lid of a kind of theft-proof type

Technical field

The utility model relates to a kind of underground pipeline inspection shaft lid, particularly relates to the novel underground pipeline inspection shaft lid of a kind of theft-proof type.

Background technology

Along with the economic development in town and country, transport development is more and more convenient, and road is also more and more.The underground pipeline basic facilities also increase and increase along with road, and inspection shaft is also more and more.Because most of inspection shaft lids are cylinder iron to make, the recovery value height, so stealing the case of underground pipeline inspection shaft lid is also constantly increasing, the incident that the uncovered inspection shaft causes casualties also constantly is reported in media, each constantly takes place tragedy, the strike that slips up of family one by one, loathsome simply.

Summary of the invention

Technical problem to be solved in the utility model provides the novel underground pipeline inspection shaft lid of a kind of theft-proof type, to remedy the deficiencies in the prior art, prevents to steal the generation with unexpected injury.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is the novel underground pipeline inspection shaft lid of a kind of theft-proof type, comprise pedestal 1 and inspection shaft lid 2, described inspection shaft lid 2 is two halves, the surface configuration of two halves inspection shaft lid joint is suitable, be provided with switch 5 in the middle of the inspection shaft lid 2, inspection shaft lid 2 flexibly connects by connection 4 and pedestal 1.

As optimized technical scheme: described half inspection shaft lid back is provided with handle 3; The surface configuration of described two halves inspection shaft lid joint is a rectangular waveform; Described connection 4 is half garden shape; Described switch 5 needs just can open with special tool; The a small amount of cast iron of described inspection shaft lid 2 usefulness is made skeleton, mixed with cement and other materials as inserts.

The invention has the beneficial effects as follows:,,, increase the difficulty of stealing and prolong the pilferage time if there is not special tool to be difficult to open for the people who steals owing to be the open syndeton of semicircle.So this a kind of inspection shaft lid can stop very effectively to be stolen, and the most effectively ensures public safety.

The novel underground pipeline inspection shaft lid of theft-proof type adopts and circular the semi open model syndeton is made skeleton with a small amount of cast iron, mixed with cement and other materials as inserts, its recovery value is very low, makes stealer profitless.

The specific embodiment

Below in conjunction with the specific embodiment the present invention is further elaborated.

With reference to accompanying drawing 1-5, inspection shaft lid 2 is two halves, and the surface configuration of two halves inspection shaft lid joint is a rectangular waveform and suitable, is provided with switches 5 in the middle of inspection shaft covers 2, and inspection shaft lid 2 flexibly connects by semicircle connection 4 and pedestal 1.

The utility model is owing to be to link to each other with pedestal 1 with half garden formula connection 4, generally should not be stolen, very convenient when construction and maintenance, after inspection shaft lid intermediate switch 5 usefulness special tools are opened, the constructor just can successively open two half inspection shaft lids 2, and the unlatching of half inspection shaft lid is lighter and handier than the unlatching of an inspection shaft lid, there is a handle 3 half inspection shaft lid back, it can alleviate labour intensity widely, after finishing, construction can shut the inspection shaft lid again more leggiero, lock switch and get final product, about semicircle inspection shaft lid just the same smooth with the road surface, automobile covers when travelling at inspection shaft like bustling with vehicles, the inspection shaft lid can not upspring by vibrations, the pedestrian can not fall into inspection shaft yet, has stopped the tragedy generation, and social effect is very obvious.
