Abstract
The utility model discloses a connecting structure for a plastic inspection well and a corrugation pipe, which comprises a well seat and a corrugation pipe. A connecting hole is arranged on the well seat, the corrugation pipe is arranged in the connecting hole, a sealing ring is arranged between the connecting hole and the corrugation pipe, and a groove is arranged on the outer wall of the head portion of the sealing ring. The wall of the connecting hole is clamped and sealed with the groove, the inner wall of the head portion of the sealing ring is an arc face, and the arc face of the sealing ring firmly wraps the arc face of a first protrusion on the end portion of the corrugation pipe arranged in the connecting hole. At least one water stop ring is arranged on the arc face of the sealing ring, and the water stop ring is clamped and sealed with the arc face of the first protrusion on the end portion of the corrugation pipe arranged in the connecting hole. The connecting structure for the plastic inspection well and the corrugation pipe has the advantages of being good in sealing effect and convenient to construct and assemble.
Description
Technical field
The utility model relates to the linkage structure of inspection shaft and under ground piping, is specifically related to the linkage structure of plastic inspection well and bellows.
Background technique
Places such as inspection shaft is the outlet, turning, the branch that are used in pipelines such as blowdown, draining or winding displacement, fall are used for maintenance and inspection or mediation cleaning.Because the construction of traditional brickwork construction inspection shaft is loaded down with trivial details, leaks easily, working life is not long, so the use of plastic inspection well will be more and more widely.The plastic inspection well that uses in the market and the linkage structure of bellows; As shown in Figure 1, comprise well seat 1, bellows 2, seal ring 4, well seat 1 is provided with connecting tube 3; Bellows 2 stretches in the connecting tube 3, in the space of bellows 2 and connecting tube 3, seal ring 4 is set.Because the caliber size of connecting tube 3 is pre-set, therefore a kind of well seat of specification can only be applicable to a kind of bellows of caliber, and underaction is convenient during use.The novel plastic inspection shaft of my company research and development recently; Be characterized in: well seat side-closed is not established opening; The size of the bellows diameter that the workman uses according to reality at the construction field (site); On well seat sidewall, cut respective connecting with perforator, such well seat has overcome the narrow limitation that the well seat of a kind of specification in the past can only corresponding a kind of bellows.And original plastic inspection well can not be applied to my the novel plastic inspection shaft of company's research and development and being connected of bellows with the linkage structure of bellows.
The model utility content
The utility model technical issues that need to address provide a kind of linkage structure of novel and plastic inspection well good sealing effect and bellows.
For addressing the above problem, the technological scheme that the utility model adopts is: the linkage structure of plastic inspection well and bellows comprises well seat, bellows; Described well seat is provided with attachment hole, places bellows in the attachment hole, is provided with seal ring between attachment hole and the bellows; Seal ring head outer wall is provided with groove; The hole wall of attachment hole and the sealing of groove chucking, seal ring head inwall is a cambered surface, the seal ring cambered surface wraps tightly first the protruding cambered surface of corrugated tube end that is placed in the attachment hole; The seal ring cambered surface is provided with at least one water-stop ring, first protruding cambered surface chucking sealing of the corrugated tube end in water-stop ring and the attachment hole.
Described seal ring head outer wall also is provided with the aproll slope, and the inwall of attachment hole is close on the aproll slope.
Described seal ring afterbody cross section is the oblique section.
The beneficial effect of the utility model: be provided with groove on the seal ring and the well seat be connected with sylphon seal with water-stop ring; The seal ring head is provided with the difficult ponding that produces in joint that the aproll slope makes seal ring and well seat in addition; Played further anti-seepage effect; Seal ring afterbody cross section is the oblique section, helps construction install convenience.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Like Fig. 2, Fig. 3, shown in Figure 4, the linkage structure of plastic inspection well and bellows comprises well seat 1, bellows 2; Well seat 1 is provided with attachment hole, places bellows 2 in the attachment hole, is provided with seal ring 4 between attachment hole and the bellows 2; Seal ring 4 head outer walls are provided with groove 7; The hole wall of attachment hole and groove 7 chucking sealings, seal ring 4 head inwalls are cambered surface 5, seal ring cambered surface 5 wraps tightly first the protruding cambered surface that is placed on bellows 2 ends in the attachment hole; Seal ring cambered surface 5 is provided with three road water-stop rings 3, first the protruding cambered surface chucking sealing of water-stop ring 3 and bellows 2 ends.Head outer wall at seal ring 4 also is provided with aproll slope 6, and the inwall of attachment hole is close on aproll slope 6, and seal ring 4 afterbody cross sections are the horn mouth oblique section.
In the above-mentioned linkage structure; The water-stop ring 3 that on seal ring 4, is provided with tightens with first protruding cambered surface of bellows 2 ends; As shown in Figure 3, water-stop ring 3 stress deformations are close to the outer tube wall of bellows 2, thereby play better seal action; Effectively stop oozing out of water, the quantity of water-stop ring 3 can be according to the seal request setting; On seal ring 4, be provided with aproll slope 6, make the seal ring 4 and the joint of well seat 1 be difficult for forming ponding, played further anti-seepage effect.Seal ring 4 afterbody cross sections are horn-like oblique section, the placement of bellows when being convenient to construction and installation.
The utility model has satisfied the novel plastic inspection shaft of my company's research and development and the needs that are connected of bellows, good sealing effect, construction install convenience.
