A kind of MPP single-wall corrugated pipe
Technical field
The utility model belongs to Country Tubular Goods field, is specifically related to a kind of MPP single-wall corrugated pipe.
Background technology
At present, the optical cable on electric power, communication and the buried protection tube of cable, can be divided into straight wall pipe and bellows.Although each performance parameter of straight wall pipe enough meets instructions for use, materials are many, and cost also increases along with the increase of materials.Straight wall pipe cannot bend in construction, increases difficulty of construction.Although the bellows that market exists is at material and constantly improve in shape, its ring stiffness is low still can not meet instructions for use, thus result in the optical cable that is embedded in underground and cable protection pipe there occurs distortion, and even the cable of the inside is damaged.
Single tube corrugated pipe is mainly connected with socket enlarging undertaking by bellmouth, and the connection sealing of this device can be poor, and bell and spigot easily comes off, and needs to purchase a large amount of connection devices, increases cost.
Utility model content
The technical problems to be solved in the utility model, is to provide a kind of easy for installation, sealing is strong, tensile strength is high MPP single-wall corrugated pipe material.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of MPP single-wall corrugated pipe, and its body is that class is cylindric, and described body comprises the first port and the second port,
Socket, its circumference around described first port is fixed, and the internal diameter of described socket is greater than the internal diameter of described body, and the external diameter of described socket is less than the external diameter of described body; Be provided with draw-in groove in described socket away from one end of described first port, described draw-in groove is evenly arranged at the inner and outer wall of described socket along the radial direction of described socket; Be provided with spring and projection in described draw-in groove, one end of described spring and the bottom of described draw-in groove are fixed, and the other end and the described projection of described spring are fixed; The both sides of described draw-in groove arrange at least two leg-of-mutton first lug bosses, and described first lug boss is MPP material;
Faucet part, its circumference around described second port is fixed, and the internal diameter of described faucet part is equal with the internal diameter of described body, and the external diameter of described faucet part is equal with the external diameter of described body; Be provided with the cavity matched with described socket between the inwall of described faucet part and outer wall, the inwall of described cavity is provided with the holddown groove matched with described projection, and the both sides of described holddown groove are provided with at least two leg-of-mutton second lug bosses.
Preferably, wherein, described socket and described faucet part are interference fit.
The advantage of this preferred version is: because tubing is single wall ripple struction, can coil very easily, can not need joint within the scope of 100 meters, also can reduce work well quantity, pipe end adopts interference fit, and structure is simple, centering property is good, and bearing capacity is high, and can withstand shocks load.
Preferably, wherein, elastic component is provided with between described first lug boss and described socket.
The advantage of this preferred version is: the existence of elastic component can make the process of connection two bellowss more smooth and convenient.
Preferably, wherein, the vertical section of described first lug boss is right-angled triangle, and the angle of its hypotenuse and horizontal plane is 15 °-30 °, and the corner of described first lug boss is smooth arc.
Preferably, wherein, the tube wall of described body is corrugated, and it has the trough of passive crest and coated cable, seamlessly transits between described crest and described trough.
Compared with prior art, the utility model is by setting up projection and the first lug boss in end, and the holddown groove corresponding with described projection and second lug boss corresponding with described first lug boss, and projection and anti-back tooth are all equipped with elastic component, what bellows can be made to fasten is more convenient, more laborsaving during installation, and have quite high bonding strength and sealing.
Accompanying drawing explanation
Fig. 1 is the overall structure figure of MPP single-wall corrugated pipe described in the utility model;
Fig. 2 is the partial sections of two MPP single-wall corrugated pipes described in the utility model when being connected with the second port by the first port;
Fig. 3 is the detail view of the first port described in the utility model when being connected with the second port.
Embodiment
Below in conjunction with legend, the utility model is further described, can implements according to this with reference to specification word to make those skilled in the art.
As shown in Figure 1, a kind of MPP single-wall corrugated pipe, its body is that class is cylindric, described body comprises the first port one and the second port 2, the tube wall of described body is corrugated, and it has the trough 4 of passive crest 3 and coated cable, seamlessly transits between described crest 3 and described trough 4.
As shown in Figure 2, the first port one of the utility model MPP single-wall corrugated pipe and the second port 2 have:
Socket 101, its circumference around described first port is fixed, and the internal diameter of described socket 101 is greater than the internal diameter of described body, and the external diameter of described socket is less than the external diameter of described body; Be provided with draw-in groove in described socket 101 away from one end of described first port one, described draw-in groove is evenly arranged at the inner and outer wall of described socket along the radial direction of described socket; Be provided with spring and projection 102 in described draw-in groove, one end of described spring and the bottom of described draw-in groove are fixed, and the other end and the described projection 102 of described spring are fixed; The both sides of described draw-in groove arrange at least two leg-of-mutton first lug bosses 103, and described first lug boss 103 is MPP material;
