Abstract

The utility model discloses an anti-theft inspection well cap, pertains to the technical field of municipal facilities and aims at providing an anti-theft inspection well cap which is not easy to be uncovered. The technical key points of the anti-theft inspection well cap is as follows: the edge or the middle position of a well cap (1) is provided with a vertically-downward hole; a lock (4) is arranged in the hole; and a movable connecting rod (12) can be matched with a boss (14) prearranged on the inner wall of a well head seat (13), wherein the movable connecting rod (12) is connected with a lock dog (6) or a locking plate (7) controlled by a lock cylinder (5), or a connector (10) fixedly connected on a lock rod (8). As the lock set which can be matched with the boss prearranged on the inner wall of he well head seat is additionally installed on the inspection well cap, the inspection well cap is not easy to be uncovered, thereby increasing the difficulty for illegal persons to steal the inspection well cap, and achieving safety and anti-theft purposes; in addition, the inspection well cap has simple structure, low cost and easy popularization and application.

Description

Anti-stealing manhole cover

Technical field

The utility model relates to a kind of anti-stealing manhole cover, belongs to the urban operating mechanism technical field.

Background technology

At present, facilities such as the water supply and draining that urban road is provided with down, coal gas, raceway generally are equipped with the maintenance inspection shaft, and it is underground that inspection shaft is fixed in, and periphery buries with cement or hituminous sandstone shop, and the well head place parallel with road ground is provided with wellhead receptacle, by the well lid shutoff.The shape of well lid has circle, square or rectangle.Material is a cast iron.Sturdy and durable because of it, and cheap and be widely used.For ease of the maintenance of inspection shaft, well lid generally all covers on wellhead receptacle, as long as cleek is inserted in the hole on the lid, iron covering can be started and move away.Invar material price rises sharply in recent years, under the ordering about of interests, some lawless people are stolen the inspection shaft lid wantonly, have both destroyed municipal infrastructure equipment, cause traffic injuries and deaths accidents such as overturning, the well that falls, tumble injury again because of well lid is stolen, caused serious harm for the people's lives and properties.

The well lid and the anti-stealing manhole cover of the value of stealing have appearred not having for this reason, on the market.So-called nothing is stolen the well lid that is worth, and is exactly the steel with screw-thread steel or other kind, makes the well lid skeleton, again with material cast moldings such as cement or resins, forms composite material.Existing anti-stealing manhole cover is roughly two kinds: a kind of is to add a latch or bolt between crib and well lid, form the constructional device of a hinge-like, because well lid links to each other with crib, and the latch part is covered and can't be extracted by ground surface materials such as cement, cause well lid to open, but be difficult to move out; The 2nd, on the basis of preceding a kind of anti-stealing manhole cover, do further to transform, promptly establish a mortise bolt mechanism or directly well lid and crib are fixed together, to increase the difficulty of pilferage with bolt in the reverse symmetry of well lid latch.

But, more than the well lid of two classes after using for many years, prove and gets nowhere.Wherein, the well lid that do not have to steal is worth is not durable, and is often rolled brokenly by car two, not only needs frequent replacing, and its skeleton is steel, thus expensive, still have and steal value.Though the second class anti-stealing manhole cover has certain pilferage difficulty, preceding a kind of anti-stealing manhole cover, as long as after well lid started, firmly thrust, pedal or pound, will rupture in the position that well lid is connected with crib; Then a kind of anti-stealing manhole cover just can be opened easily as long as possess light instruments such as die nut, implements as above step then and can steal well lid.

Summary of the invention

The purpose of this utility model is to provide a kind of anti-stealing manhole cover that can not raise well lid easily.

Its technical scheme is: a kind of anti-stealing manhole cover, comprise lockset, it is characterized in that: the edge of described well lid or position placed in the middle are provided with hole vertically downward, lock body is installed in the hole, by the dead bolt or the locking plate of lock core control or be fixed in the movable rod that the connector on the locking bar connects, can cooperate with default boss on the wellhead receptacle inwall.

Described lockset is mechanical lockset or electrical type lockset.

Its technique effect is: install the lockset that can cooperate additional owing to adopt to cover with default boss on the wellhead receptacle inwall at inspection shaft, so make that the inspection shaft lid can not be raised easily, thereby increased the difficulty that lawless people is stolen the inspection shaft lid, realization safely, antitheft purpose.And it is simple in structure, and cost is not high, is easy to apply.

The specific embodiment

Embodiment 1.This routine anti-stealing manhole cover is adapted to the inspection shaft lid that links to each other by latch or bolt between wellhead receptacle and the well lid.As shown in Figure 1, edge at well lid 1 and latch or the reverse diagonal angle of bolt is provided with hole vertically downward, lock body 4 is installed in the hole, dead bolt 6 by lock core 5 controls, cooperate with boss 14 default on wellhead receptacle 13 inwalls, insert lock core by key and rotate, lock core drives dead bolt and stretches out or shrinks, inspection shaft lid and wellhead receptacle lock are connected in fact or open and separates.

Dead bolt 6 also can replace (see figure 2)s by locking plate 7, inserts rotational lock core by key, drives locking plate and rotates, and is connected or opens and separate inspection shaft lid and wellhead receptacle lock are real.

In order to prevent pollution and the corrosion to lockset of dust and rainwater, the end, aperture that lock body is installed is provided with dustproof and waterproof blind nut 2, is provided with waterproof gasket 3 between dustproof and waterproof blind nut and the tapered end.

Embodiment 2.This routine anti-stealing manhole cover is adapted to the inspection shaft lid that no latch between wellhead receptacle and the well lid or bolt link to each other.As shown in Figure 3, be provided with hole vertically downward in well lid 1 position placed in the middle, lock body 4 is installed in the hole, be connected with connector 10 on the locking bar 8 by lock core control, at least be provided with connector 11 (see figure 4)s of a pair of symmetry on the connector, connector is hinged with movable rod 12 respectively, and the other end of movable rod passes the boss of presetting on the hole offered well lid lid skirt lower end and wellhead receptacle 13 inwalls 14 and cooperates.Key inserts lock core and rotates, and lock core is by the locking bar device that is in transmission connection, and connector drives movable rod and stretches out or shrinks, inspection shaft lid and wellhead receptacle lock are connected in fact or open and separates.

Embodiment 3.This routine anti-stealing manhole cover is adapted to the inspection shaft lid that links to each other by latch or bolt between wellhead receptacle and the well lid.As shown in Figure 5, the edge at well lid 1 and latch or the reverse diagonal angle of bolt is provided with hole vertically downward, and the hole is " T " shape or " L " shape.Lock body 4 is installed on the edge of well lid reverse side, by the bolt 7 of lock core 5 control, cooperates with boss 14 default on wellhead receptacle 13 inwalls, by " L " key of type inserts rotation in the lock core, the drive bolt rotates, and is connected or opens and separate inspection shaft lid and wellhead receptacle lock are real.
