Abstract

The utility model relates to the technical field of the mechanical structure technology, the industrial lock metal technology, the casting and the casting technology, in particular to an antitheft metal well cover, wherein a lock structure is large-sized and simplified, and an unlocking key is complicated, mechanized or intellectualized. The antitheft metal well cover (with a lock) consists of a well cover, a well seat, a lock tongue, a retaining spring and an unlocking key. The antitheft metal well cover has the advantages of simple structure, lockpicking resistance, smashing resistance, malicious unlocking resistance, firm locking and convenient unlocking; and the self-locking well cover also has the advantages that a stud is cast by the die-casting technology, the compressive strength is doubled, and the well cover is prevented from being broken forever and is safe and reliable.

Description

Antitheft metal well lid

Technical field: frame for movement, metalwork, casting technique, industrial lockset

Background technology: along with the human civilization progress, the urbanization on gregarious ground, science and technology development has been quickened the modernization in city and the variation of city function.The development of society has brought the many contradictions of chopsticks again; a large amount of labours city of crowding into; employment trouble over a long time, unemployment rate height; brought the existence crisis for the population in the city of crowding into; in the face of crisis; everyone morals impel everyone to make different behavior performances with psychological bearing capability, and this behavior performance certainly will have influence on public civil order.

Because the international market metal price rises suddenly and sharply year after year, and as the metal well lid of urban infrastructure, bar, frame, case, cabinet door etc., the centuries just changes in shape to some extent, has no on the function to improve, and is in original self lock-free state.The unlatching of leting people, easily displacement, easily upset can get conveniently, even the professional embezzling group at the city metallic facility occurred, and the road trap in city has become the cosmopolis public hazards.

For public hazards are stopped in elimination; the cement well lid that large quantities of no recovery values successively occurred; the impurity plastics; glass fiber reinforced plastic; flyash; and the well lid product of some other materials; passing along with service time; the defective of these well lid products all is completely exposed; heavy; it is difficult to open; poor plasticity; easily aging; not shock resistance; compressive strength is low; frangible; the unlatching of leting people; can not protect self facility in the well; the turnover rate height has increased management difficulty, does not only solve the city public hazards; make it to aggravate day by day, fact proved that the advantage of metal well lid is that other material well lid can't replace.Solved the metal well lid self is antitheft, also just solved the city public hazards.

So the invention that the present declares is a kind of " antitheft metal well lid ", when this invention utilizes the casting of metal well lid, cast out placing the support of dead bolt and the key eye disjunctor of unlatching key turnover.Be cast with locking point and dead bolt sheath on the well seat.Well lid and well seat be by well lid upper lock tongue locking one voluntarily, pick-proof, anti-ly pound, the compressive strength height, anti-malice is opened.The use private key is opened, and laterally locking is vertically opened.

The specific embodiment: with reference to the accompanying drawings, be cast with the dead bolt support at well lid, the dead bolt of packing into is furnished with the retaining spring, and well lid is self-locking on the well seat, utilizes special opening key operated, finish the metal well lid self is antitheft.

(accompanying drawing 1) illustrates: the monolateral unlatching well lid of both sides locking, form by well lid 1, well seat 2, rectangular stripe shape keyhole 3, dead bolt support 4, dead bolt 5, unlatching Ji groove 6, unlatching retaining spring 7, retaining spring locating slot 8.

(accompanying drawing 2) illustrates: the both sides locking, and one-eyed with driving a well lid, form by well lid 1, well seat 2, rectangular stripe shape keyhole 3, dead bolt support 4, dead bolt 5, unlatching Ji groove 6, dead bolt retaining spring 7, retaining spring alignment pin 8, dead bolt anti-prying case 9.

(accompanying drawing 3) illustrates: the special opening key, key lifts hand shell 1, flexible tooth bar 2, tension spring 3, commutation left and right sides Lian La gear 4, band tooth are opened Ji 5 about elastic, formed up and down by opening.

Open theory: hold the key shell and lift hand 1, depress flexible tooth bar handle 2, tension spring 3, compressed energy-storage, commutation connects gear 4 rotations about flexible tooth bar downlink drive, opens in the 5 retraction shells 1 of Ji about the band tooth is elastic.Key is inserted well lid eye 3, under deliver to the position, half-twist, unclamp the flexible tooth bar handle of depressing 2, tension spring 3, it is up to discharge flexible tooth bar, drives to connect gear 4 rotations, open Ji 5 about drive, stretch out about outwards by shell 1 and to put in place, on lift hand 1, make and open Ji point 5 and insert and open Ji grooves 6, tooth bar handle 2 contracts under the pressure stretch, tension spring 3 compressed energy-storages, tooth bar downlink drive connect gear 4 and rotate, and open Ji 5 Ji points about drive and catch on opening groove 6, pulling dead bolt 5 row that inwardly contracts, dead bolt 5 release lock close point well seats 2 are firmly upwards mentioned together with well lid simultaneously, and unlatching is finished.

Locking: only need well lid 1 is aimed at well seat 2, the deadweight of well lid has forced slope angle dead bolt 5 to promote retaining spring 7 and has retreated, and well lid 1 falls to putting in place, and dead bolt 5 stretches out retaining spring 7 and resets, and locking is finished.

The explanation of accompanying drawing drawing: Fig. 1 is the both sides locking, the monolateral unlatching well lid of eyes;

Fig. 2 is the both sides locking, and is one-eyed with driving a well lid;

Fig. 3 is the special opening key.
