Abstract
The utility model belongs to a technical field of well covers, which discloses a waterproof and theft protective well cover. The main technical characteristics are that: the utility model comprises a movable magnetic switch, a well cover body and a well ring body which has an inner ring and an outer ring; the inner ring of the well ring body is provided at least two concave grooves; the bottom of the well cover body is provided with L-shaped cover liftings whose shape, size and quantity match with the shape, size and quantity of the concave grooves; a sealing circle is arranged between the well cover body and the inner ring of the well ring body. When the waterproof and theft protective well cover of the utility model is installed, the sealing circle is arranged on the upper surface of the inner ring, and the L-shaped cover liftings are made to align with the concave grooves of the well ring body by the magnetic switch, then the well cover body is put down and rotated. At the time, the sealing circle is tightly pressed on the inner ring of the well ring body by the well cover body, and the well cover body and the well ring body are strictly sealed so that no water can flow in, thereby realizing the functions of theft protection as well as waterproof.
Description
Technical field
The utility model belongs to the well lid technical field, relates in particular to a kind of waterproof, anti-stealing manhole cover.
Background technology
In urban construction, manhole, gate shaft, measuring well that is used for water supply and drainage, combustion gas and heat distribution pipeline, electricity cable, telecom communication etc. etc. all needs well lid.The well lid of current use adopts material such as cast iron to make mostly, and the stolen phenomenon of well lid takes place repeatedly, not only influences traffic, and cause very big danger can for vehicle and pedestrian, especially at night, dangerous can be bigger.Stolen in order to prevent well lid, people have studied a lot of methods, the patent No. is 96218112.9, name is called the anti-stealing manhole cover device that the patent document of " a kind of rotation anti-stealing manhole cover device " provides, make the well lid body screw, open by magnetic switch, played antitheft effect, but, made that whole manhole lid device water resistance is not very desirable because its sealing ring is arranged on walling crib body top.
The utility model content
Problem to be solved in the utility model just provide a kind of can be antitheft again can waterproof well lid.
For addressing the above problem, the technical solution adopted in the utility model is: comprise removable magnetic switch, well lid body and have the walling crib body of interior ring, outer shroud, have at least two grooves on the interior ring of walling crib body, the bottom of well lid body is provided with the L type lid ear that shape, size, quantity and groove are complementary, and is provided with sealing ring between the interior ring of described well lid body and walling crib body.
Its additional technical feature is: the degree of depth of described groove is less than the width of interior ring, and bottom portion of groove has base frame, and the thickness of base frame and the width of sealing ring are complementary; The bottom of described well lid body is provided with the projection that shape, size, quantity and groove are complementary; The bottom of described walling crib body is provided with at least one lower margin; The outer shroud of described walling crib body is provided with walling crib body reinforcing rib; The bottom of described well lid body is provided with well lid body reinforcing rib.
Waterproof provided by the utility model, anti-stealing manhole cover are compared with prior art, between the interior ring of well lid body and walling crib body, be provided with sealing ring, ring upper surface in during installation sealing ring being arranged on, with magnetic switch the well lid body is mentioned then, L type lid ear is aimed at the well lid body is put down behind the groove of walling crib body and rotated, taking off magnetic switch then gets final product, this moment, the well lid body tightly was pressed in sealing ring on the interior ring of walling crib body, make that strictness seals between well lid body and the walling crib body, water can be by not flowing between the two, thereby play waterproof effect.In addition, bottom portion of groove has base frame, and the thickness of base frame and the width of sealing ring are complementary, and makes sealing ring can not produce the slit at groove, and sealing effectiveness is better.The bottom of well lid body is provided with projection, and the rotary well cover body makes projection snap in groove, and the well lid body can arbitrarily not rotated after installing.The bottom of walling crib body is provided with at least one lower margin, makes the walling crib body combine firmly with the basis.Be provided with walling crib body reinforcing rib and well lid body reinforcing rib then plays reinforcement effect to whole well lid.Dismounting is during well lid, with magnetic switch with carry on the well lid body contacts, make projection extract groove, rotary well cover body is then mentioned the well lid body after making the groove of L type lid ear aligning walling crib body, the well lid body just is separated with the walling crib body.
Description of drawings
Fig. 1 is the structure sectional view of the utility model waterproof, anti-stealing manhole cover;
Fig. 2 is a walling crib body structure schematic diagram.
The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing the utility model waterproof, anti-stealing manhole cover.
As shown in Figure 1, the utility model waterproof, anti-stealing manhole cover comprise removable magnetic switch 1, well lid body 2 and walling crib body 3, magnetic switch 1 is made of magnetic switch handle 4 and permanent magnet 5, ring 6, outer shroud 7 in walling crib body 3 has, outer shroud 7 is provided with walling crib body reinforcing rib 8, the bottom of walling crib body 3 is provided with lower margin 9, and the bottom of well lid body 2 is provided with L type lid ear 10, projection 11 and well lid body reinforcing rib 12, is provided with sealing ring 13 between the interior ring 6 of well lid body 2 and walling crib body 3.As shown in Figure 2, have groove 14 on the interior ring 6 of walling crib body 3, the degree of depth of groove 14 is less than the width of interior ring 6, and base frame 15 is arranged at groove 14 bottoms, and the width of the thickness of base frame 15 and sealing ring 13 is complementary.
During installation, sealing ring 13 is arranged on interior ring 4 upper surfaces, open the magnetic switch handle 4 of magnetic switch 1 then, permanent magnet 5 begins effect and holds well lid body 2, catch magnetic switch 1 that well lid body 2 is mentioned this moment, L type lid ear 10 is aimed at well lid body 2 is put down behind the groove 14 of walling crib bodies 3 and rotated, make projection 11 snap in groove 14, turn off magnetic switch handle 4 then, take off magnetic switch 1 and get final product, this moment, well lid body 2 tightly was pressed in sealing ring 13 on the interior ring 6 of walling crib body 3, made that strictness seals between well lid body 2 and the walling crib body 3, water can be by not flowing between the two, thereby play waterproof effect.In addition, base frame 15 is arranged at groove 14 bottoms, and the width of the thickness of base frame 15 and sealing ring 13 is complementary, and makes sealing ring 13 can not produce the slit at groove 14 places, and sealing effectiveness is better.The lower end of walling crib body 3 is provided with lower margin 9, makes walling crib body 3 combine firmly with the basis.12 of walling crib body reinforcing rib 8 and well lid body reinforcing ribs play reinforcement effect to whole well lid.
