Description
Technical field
The present invention relates to store well lid, relate in particular to a kind of cellar for storing things well lid with mechanical code lockset and camlock location that reduces manufacturing cost, raising safety, strengthens stability, raising pick-proof performance and raising vibration resistance.
Background technology
The cellar for storing things well lid using on existing market is of a great variety, and structure is also multimodal various.Use metal well lid to be widely worth owing to himself having to recycle, all consider in design its theftproof performance, but along with international and domestic terrorist activity and people are that behavior and the possibility of destroying facility in well of going into the well increases gradually, therefore prevent from that other people from arbitrarily opening to enter this anticrime function in well and become more urgent.
The metal well lid of prior art comprises manhole cover base, the well lid mating with manhole cover base, and well lid connects as one by bolt and manhole cover base, go into the well cover rim bolt upset of External Force Acting; Between well lid and manhole cover base, be provided with jump ring, under External Force Acting, realize well lid and be fixedly connected with the clamping of manhole cover base.In use, workman adopts pry tool to prize well lid [prize in process at this, workman very difficultly just can pry open well lid] to this structure, and the well lid upset after opening is at manhole cover base side; Workman enters underground work again.The well lid that is positioned at manhole cover base side is easy to turn back under external force [this external force mainly refers to that other people's mistake causes sealed external force by well lid shake-up to manhole cover base] on manhole cover base, and by manhole cover base sealing, to underground work, workman causes potential safety hazard; Workman also easily stirs well lid when turnover well head, causes mechanical wounding, and when meeting water flood, well lid may be rebuild or renovate into potential safety hazard by punching simultaneously.On existing market, adopt in addition electric lockset to prevent the technology that well lid is opened, but in freezing winter and in sultry summer, expose to the sun and rain, reliability extreme difference in environment for use that loaded vehicle rolls.
The technical scheme that Chinese patent mechanical code well lid is announced has to a certain degree solved above-mentioned technical problem [patent No. of this mechanical code well lid is 201320363471X].In the technical scheme that described mechanical code well lid is announced, adopted coded lock device, this coded lock device generally at least needs to adopt three covers in use, effectively realized anti-unlatching, but in use procedure, between well lid and manhole cover base, out-of-flatness easily produces vibration, when vehicle by time can produce noise, stability reduces with the passing of service time; Due to smoother between the cipher wheel top card of this coded lock device and the laminating contact surface of manhole cover base, when well lid is upwards about, mention just can rotational lock core, just can attempt utilizing feel to carry out decryption by rotational lock core, and safety is lower.
In sum, lower, the poor stability of the mechanical code well lid safety of prior art and vibration resistance are poor.
Summary of the invention
The object of this invention is to provide a kind of cellar for storing things well lid with mechanical code lockset and camlock location that improves safety, enhancing stability, improves pick-proof performance and raising vibration resistance.
For realizing the technical scheme that above-mentioned purpose of the present invention adopts, be: a kind of cellar for storing things well lid with mechanical code lockset and camlock location, comprise manhole cover base, with the well lid that manhole cover base internal diameter mates, be arranged on the mechanical code lockset on well lid; Wherein: on described manhole cover base inwall, have installation heavy stand, well lid is positioned to be installed on heavy stand; On the manhole cover base inwall above installation heavy stand, be provided with to projecting inward inner convex platform, on inner convex platform, be provided with installation detent;
On the outer wall of described well lid, have outwardly installation locating convex block, this installation locating convex block mates with installation detent;
Described mechanical code lockset is at least 2 covers, and this mechanical code lockset is positioned on the well lid that locating convex block opposite is installed.
Due to said structure, workman is when installing well lid, first the installation locating convex block of well lid is inserted to installation detent location is installed, then turn tight retaining mechanism, then rotating machinery formula coded lock [this mechanical code lockset adopts the lock device of announcing in China Patent No. 201320363471X]; By mechanical code lock, have effect and guaranteed the anti-openability of well lid, whole well lid is only unclamping open mechanical code lockset after cam lock holding mechanism in the situation that again and well lid could taken out; Service worker is opened well lid when maintenance can be completely separated with manhole cover base by well lid, the safety that has also just improved service worker.Meanwhile, inner convex platform can block the outer of well lid, and external force machine tool, without prizing origin of force, has further improved pick-proof performance, anti-mechanical damage ability and theftproof.Lockset can adopt two covers, can reduce manufacturing cost.
