Abstract
The utility model disclose an underground pipeline inspection well cover, which comprises a cover body and a cover base (2), wherein the cover body (1) is mounted on a bearing table of the cover base (2); opening holes (12) are formed on the top surface of the cover body (1); and an outer ring groove (11) is formed on the side surface of the cover body (1); a seal ring is mounted in the outer ring groove (11); and antiskid ribs are arranged on the bearing table of the cover base (2). The underground pipeline inspection well cover can prevent the displacement and noise generation of the cover body and has the advantages of good sealing performance, convenience in opening, stability, fastness and long service life.
Description
Technical field
The utility model relates to underground piping system, relates in particular to a kind of underground pipeline manhole well lid.
Background technology
At present, underground pipeline such as underground water pipeline, sewage vent line, raceway, communication conduit etc. are all built the manhole (claiming inspection shaft again) that is communicated with ground when laying, so that underground pipeline carried out work such as examination and maintenance.Manhole is provided with well lid, is used to close and the leakage check well.
Traditional cast iron class well lid quality is heavy, and is not attractive in appearance, and often stolen because recovery value is arranged, and therefore, uses the well lid of composite material to become trend of the times.Composite material manhole well lid does not have recovery value, light weight, and color tunable can be beautified the environment, but existing well lid is because phenomenons such as running, jump, ring appears in light weight easily.In case displacement just is difficult to reach the effect of sealing, the gas in the underground pipeline is emerged from the slit, and contaminated environment is detrimental to health.The shortcoming that existing well lid is inconvenient to open in addition is difficult to recover well original sealing performance after opening well lid.
The utility model content
The present invention has overcome deficiency of the prior art, and the underground pipeline manhole well lid of a kind of convenient unlatching and good seal performance is provided.
In order to realize above-mentioned purpose, adopt following technical scheme:
A kind of underground pipeline manhole well lid comprises lid and cage, and lid is installed on the plummer of cage, the lid end face is provided with open hole, described lid side is provided with outer groove, and sealing ring is installed in the outer groove, and the plummer of described cage is provided with anti-skidding muscle.Sealing ring is installed in the outer groove, stable firmly can guarantee the sealing performance of well lid, cooperates with anti-skidding muscle on the cage, can prevent that lid is shifted easily, can not occur running, jumps, phenomenon such as sound.
In the such scheme, be provided with sealing-plug in the described open hole, can seal, prevent that the gas of underground pipeline from emerging from open hole open hole.The open hole limit is provided with the protection muscle, described protection muscle and sealing-plug is contour or a little more than sealing-plug, be used to guarantee sealing-plug firmly, prevent that sealing-plug from contacting with external object and become flexible easily.The open hole limit is provided with recessed finger position, makes things convenient for the taking-up of sealing-plug.
In the such scheme, described lid end face is provided with anti-skidding line, can increase the friction of lid end face, avoids owing to the lid end face too smoothly has an accident.Anti-skidding line can design different shapes, makes well lid more attractive in appearance.The lid end face also is provided with the sign position, is used to identify various information.The lid bottom surface is provided with reinforcing rib, and lid integral body is strengthened, and makes lid more sturdy and durable, increases application life.
Compared with prior art, the utility model can prevent effectively that phenomenons such as noise from appearring being shifted, sending in lid, good seal performance, and it is convenient to open, and firmly stable, long service life.

Fig. 2 is a sectional drawing of the present utility model;
Fig. 3 is a lid top surface structure schematic diagram of the present utility model;
Fig. 4 is a lid of the present utility model bottom surface structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Each parts of the present utility model as shown in Figure 1; comprise lid 1, cage 2, sealing ring 3 and sealing-plug 4; lid 1 side is provided with outer groove 11, and end face is provided with open hole 12, protection muscle 13, finger position 14, anti-skidding line 15, sign position 16, and cage 2 is provided with anti-skidding muscle 21.Section of the present utility model as shown in Figure 2, lid 1 is installed on the plummer of cage 2, sealing ring 3 is installed in the outer groove of lid 1.
Lid end face of the present utility model and bottom surface are respectively as shown in Figure 3 and Figure 4.Protection muscle 13 and finger position 14 are arranged on open hole 12 limits; it is firmly stable that protection muscle 13 can guarantee to fill in the sealing-plug 4 of open hole 12; prevent sealing-plug 4 from contacting and loosening easily with external object; finger position 14 is used for the taking-up of sealing-plug; directly pointing 14 places, position extraction of closure plug 4 easily with finger; need not upgrade kit, simple and efficient.Anti-skidding line 15 is arranged on the many places of lid 1 end face, increases the friction of end face comprehensively, and sign position 16 can identify information such as title, model.Lid 1 bottom surface is provided with reinforcing rib 17, and lid 1 integral body is strengthened, and makes lid 1 more sturdy and durable, increases application life.
During installation, elder generation is installed to sealing ring 3 in the outer groove 11 of lid 1, then lid 1 is installed on the plummer of cage 2, sealing-plug 4 is filled in the open hole 12 to get final product at last.During unlatching, only need to utilize finger position 14 extraction of closure plug 4 easily, but just opening cover 1.
