Description

Anti-stealing manhole cover

Technical field

The utility model relates to a kind of well lid, more particularly, relates in particular to a kind of anti-stealing manhole cover.

Background technology

Existing well lid, generally its upper surface is planar design, and the general weight capacity of this well lid is relatively poor, breaks easily, and application life is short; And, influence peripheral living environment because the unreasonable structure of well lid and well seat can produce vibration during vehicle process well lid, thereby noise occur; Simultaneously, existing well lid and well seat relatively simple for structure, well lid is easy to open, and the stolen phenomenon of well lid therefore often occurs, the losing of well lid, both personal safeties of entail dangers to passerby can make pollutant such as rubbish get into the interior of articles that well lid covers again; If well lid is used for water channel, will cause the obstruction of water channel, if well lid is used for communications optical cable, will influence maintenance in the future.

The utility model content

The purpose of the utility model is the deficiency to above-mentioned prior art, and the anti-stealing manhole cover that a kind of weight capacity is strong, life cycle is long and theftproof performance is good is provided.

The technical scheme of the utility model is achieved in that a kind of anti-stealing manhole cover, comprises the lid and the bearing that cooperatively interact, and wherein said lid upper surface is an arcwall face, is distributed with separate bulge loop at the lid upper surface; Be provided with movable dead bolt in lid one side, be provided with fixedly dead bolt at the lid opposite side; On the bearing sidewall, be respectively equipped with and movable dead bolt and fixing dead bolt corresponding positioning hole; Described movable dead bolt is through the telescopic moving of rotation toggle mechanism.

In the above-mentioned anti-stealing manhole cover, described lid bottom is provided with bearing, and described movable dead bolt is movably arranged on the bearing; Described rotation toggle mechanism is made up of jack, position block and slot, and described slot is arranged on the bearing, and described jack is arranged on the lid relative with slot; Described position block is fixed on movable dead bolt and the corresponding side of jack.

In the above-mentioned anti-stealing manhole cover, described bearing is provided with and the corresponding vibrationproof cushion rubber of lid.

In the above-mentioned anti-stealing manhole cover, described bearing inboard is provided with locating ring, in locating ring, is equipped with connecting rod; Connecting rod one end is connected with lid, and the connecting rod other end is provided with the external diameter block bigger than locating ring internal diameter.

After the utility model adopts said structure; Through the lid upper surface is designed to arcwall face, and bulge loop is set, makes the load-bearing of lid and stress-bearing capability strengthen greatly at the lid upper surface; Cooperate bulge loop simultaneously, make the lid upper surface be easy to draining and have anti-skidding effect; Movable dead bolt and rotation toggle mechanism with matching are set on lid, make well lid be difficult to be opened under the situation of private key not having, strengthened the anti-theft feature that advances lid greatly; Further, the vibrationproof cushion rubber that adapts with lid is set on bearing, has certainly separated vehicle effectively through out-of-date, the well lid pressurized is prone to vibration, the problem that noise is big.
