Abstract

The utility model relates to a double-layer six-point self-locking-type safe anti-theft well lid which comprises a well lid base and a well lid body. The well lid is characterized in that the well lid base is in a circular ring shape, an upper step layer and a lower step layer are arranged on the inner wall of the well lid base, three locking groove openings are evenly formed in each step layer, the upper step layer and the lower step layer are arranged in parallel, the locking groove openings in the upper step layer and the lower step layer are arranged in a staggering mode, three locking blocks are evenly arranged at the edge of the bottom face of the well lid body, the locking blocks correspond to the locking groove openings in position, two opening holes are formed in the middle of the well lid body and are of a cavity structure without force points, the opening holes are formed in the bottom face of the well lid body, the cavity structure without force points is divided into an upper cavity and a lower cavity, the upper cavity is a cavity body close to the well lid direction, the lower cavity is placed at the lower end of the cavity structure without force points, the cavity body of the upper cavity is in a circular shape, and the cavity body of the lower cavity is in an outward-expanding-trumpet shape. Locking grooves are formed through the upper step layer and the lower step layer which are arranged in a staggering mode and limit the well lid body with the locking blocks, and the well lid body is effectively prevented from being lost, or washed out and away by water.

Description

Double-deck 6 self-locking safety anti-stealing manhole covers

Technical field

The utility model relates to a kind of double-deck 6 self-locking safety anti-stealing manhole covers, belongs to a kind of new pattern manhole cover structure of municipal infrastructure.

Background technology

Well lid is infrastructure essential in a kind of city, although people relatively ignore this facility of well lid during daily life in city, but the loss of well lid and damage have also caused the infringement on many properties and the person, such as the loss of well lid on normal motorway easily causes wheel to fall in well, when the speed of a motor vehicle is too fast, more there will be major traffic accidents; Pedestrian falls in the sewer that there is no well lid accidentally can cause the infringement on health, more likely threat to life.The measure of taking for the well lid of losing repeatedly at present produces little effect, although now had the well lid with dedicated lock, pattern manhole cover lock easily causes damage, can not guarantee appropriate maintenance.

Summary of the invention

The purpose of this utility model is to provide a kind of double-deck 6 self-locking safety anti-stealing manhole covers, and it forms locked groove by two-layer up and down step that dislocation is arranged, the well lid with lock dog is carried out spacing, effectively prevents the loss of well lid or is gone out, washes away by current.

The technical solution of the utility model is achieved in that double-deck 6 self-locking safety anti-stealing manhole covers, by well lid base, well lid forms, it is characterized in that: well lid base is annular, on the inwall of well lid base, there is bilevel step, on every layer of step, evenly have three locked groove openings, bilevel step is arranged in parallel, locked groove opening dislocation on upper and lower two-layer step is arranged, the bottom edge of well lid has been evenly arranged three lock dogs, lock dog is corresponding with the position of locked groove opening, in the middle of well lid, have two open holes, open hole is the cavity structure without origin of force, it is positioned at well lid bottom surface, cavity structure without origin of force is divided into epicoele and cavity of resorption two parts, epicoele is the cavity that approaches well lid direction, cavity of resorption is positioned at the lower end without the cavity structure of origin of force, the cavity of epicoele is circular, the cavity of cavity of resorption is expand outwardly tubaeform.

The angle expanding outwardly of described cavity of resorption is 30-45 °.

Lock dog on described well lid is L shaped.

Good effect of the present utility model is that it passes through the two-layer up and down step formation locked groove that dislocation is arranged, to the well lid with lock dog, carry out spacing, effectively prevent the loss of well lid or gone out, wash away by current, saved municipal well lid and safeguarded fund, reduced city Sewage well cover and lost the potential safety hazard causing.

Accompanying drawing explanation

Fig. 1 is well lid understructure figure of the present utility model.

Fig. 2 is manhole cover structure figure of the present utility model.

Fig. 3 is the sectional drawing without origin of force draw-in groove of the present utility model.

Fig. 4 is overall structure figure of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further: as Fig. 1, 2, shown in 3, double-deck 6 self-locking safety anti-stealing manhole covers, by well lid base 1, well lid 2 forms, it is characterized in that: well lid base 1 is annular, on the inwall of well lid base 1, there is bilevel step 3, on every layer of step 3, evenly have three locked groove openings 4, bilevel step 3 is arranged in parallel, locked groove opening 4 dislocation on upper and lower two-layer step 3 are arranged, the bottom edge of well lid 2 has been evenly arranged three lock dogs 5, lock dog 5 is corresponding with the position of locked groove opening 4, in the middle of well lid, have two open holes, open hole is the cavity structure 6 without origin of force, it is positioned at well lid 2 bottom surfaces, cavity structure without origin of force is divided into epicoele 6-1 and cavity of resorption 6-2 two parts, epicoele 6-1 is the cavity that approaches well lid direction, cavity of resorption 6-2 is positioned at the lower end without the cavity structure of origin of force, the cavity of epicoele 6-1 is circular, the cavity of cavity of resorption 6-2 is expand outwardly tubaeform.

The angle expanding outwardly of described cavity of resorption 6-2 is 30-45 °.

Lock dog 5 on described well lid 2 is L shaped.

?between the step of well lid base 1, be highly 11-15mm, lock dog 5 and be 44mm without the height of the cavity structure 6 of origin of force.

As shown in Figure 4, well lid base 1 is fixed on lower well mouth place, well lid 2 covers on well lid base 1, after the lock dog 5 of well lid 2 is made uniform with the locked groove opening 4 on first floor step 3, lock dog 5 inserts from locked groove opening 4 positions, well lid 2 horizontal levels decline, well lid 2 now clockwise or rotate counterclockwise, the locked groove opening 4 that lock dog 5 is made uniform on second layer step 3 again also passes the locked groove opening 4 of second layer step 3, well lid 2 drops to terminal level position, well lid 2 embeds in well lid base 1, thereby last rotary well cover 2 again touches the bottom connection of lock dog 5 and the 2nd layer of step 3 reaches spacing object, two open holes that have in the middle of well lid 2 are used for inserting dedicated handle rotary well cover 2 and use, open hole is the cavity structure 6 without origin of force, the cavity that approaches the epicoele 6-1 of well lid 2 directions due to the cavity structure 6 without origin of force is circle, cavity of resorption 6-2 cavity without cavity structure 6 lower ends of origin of force is expand outwardly tubaeform, centrum is 30-45 ° of degree, it must be used in conjunction with to realize with dedicated handle and install, and could realize antitheft object.
