Description

Suspension type sealing connection structure and pipeline connection unit Technical Field The application relates to the field of pipes, in particular to a suspension type sealing connection structure and a pipeline connection unit. Background The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. The pipe is a material necessary for construction engineering, and commonly used water supply pipes, drain pipes and the like. For convenience in transportation, the length of each pipe is not too long, and the pipe needs to be in butt joint on the site. In the construction process of two pipes, it is difficult to ensure that the two pipes are centered (namely the axes of the two pipes coincide), and when the two pipes deviate greatly, the sealing ring can incline or deform, so that the sealing performance of the pipeline is reduced. Disclosure of Invention In view of the above, the present application provides a suspension type sealing connection structure and a pipeline connection unit, which can improve sealing performance. In order to achieve the above purpose, the present application is realized by the following technical scheme: A suspension type sealing connection structure is characterized by comprising a socket section, a sealing ring and a socket section for receiving the socket section, wherein an anti-falling groove and a sealing matching section for matching with the sealing ring are arranged on the socket section, the socket section comprises an inner pipe layer and an outer pipe layer, the two axial ends of the outer pipe layer are integrally connected with the inner pipe layer, a cavity is formed between the inner pipe layer and the outer pipe layer, accordingly, the main body part of the outer pipe layer is separated from the inner pipe layer, corrugated sections with concave-convex alternation and a clamping part clamped with the anti-falling groove are arranged on the main body part of the outer pipe layer, one trough in the corrugated sections is a sealing installation groove for installing the sealing ring, and the sealing ring is installed in the sealing installation groove. According to the suspension type sealing connection structure, the concave-convex alternate corrugated sections are arranged on the outer pipe layer, and the corrugated structure can improve the circumferential strength of the outer pipe layer. Besides, two ends of the outer pipe layer are connected with the inner pipe layer, the rest parts are in a suspended state, the sealing ring is arranged in one trough of the corrugated section, and when the socket section and the socket section are in butt joint, if the inner pipe layer and the socket section are eccentric, the corrugated section is easy to deform under the compression of the socket section, so that the sealing ring is automatically centered. When the pipe is installed and buried and extruded by external force, when the bell mouth and the spigot of the two connected pipes are displaced horizontally or up and down (not axially), the suspended outer pipe layer, the sealing ring and the clamping part can be ensured not to move relatively, so that the tightness is ensured, and the effect of the pipe is similar to that of a damper. And after the pipeline is installed and buried, in the geological settlement process, two pipes can generate axial drawing force, the drawing force can act on the corrugated section due to the clamping connection between the anti-falling part and the anti-falling groove, and the corrugated section is of a concave-convex single-wall structure and can generate axial compression deformation, so that the axial buffering effect is achieved, and the pipe is prevented from being broken. In some embodiments, the clamping part comprises connecting teeth integrally connected with the corrugated section, the connecting teeth are connected with the corrugated section and the outer pipe layer through connecting rings, the connecting rings comprise a plurality of concave rings and convex rings which are sleeved on the periphery of the connecting teeth, the concave rings and the convex rings are alternately arranged in a concave-convex mode and are sleeved with each other to form a telescopic corrugated structure, when the socket section and the socket section are in butt joint, the connecting teeth are pressed by the socket section and can radially contract through the connecting rings, so that the connecting teeth can enter the anti-falling grooves, and after the connecting teeth enter the anti-falling grooves, the connecting teeth rebound radially to form clamping connection with the anti-falling grooves. The connecting ring can drive the connecting teeth to radially change, so that the connecting teeth can be radially compressed when being pressed, and can radially and automatically reset when not being acted, and the connecting teeth can enter the anti-falling grooves to
