Description

Technical Field

[0001] The utility model relates to the technical field of connection structures, and particularly relates to a sewage pipe connection structure. Background Art

[0002] A sewage pipe refers to a system composed of pipes for collecting and discharging sewage, wastewater, and rainwater, as well as their auxiliary facilities. It is widely used in urban drainage, underground engineering drainage, and other fields. The commonly used connection between sewage pipes is flange connection. First, a flange plate is fixedly installed at each end of the two sewage pipes respectively, then a flange gasket is added between the two flange plates, and finally, the two flange plates are tightened with bolts to make them closely combined. This is a detachable joint.

[0003] Although the traditional sewage pipes can be connected through flange plates, during the connection process, it is necessary to tighten multiple bolts between the two flange plates, and the operation is rather cumbersome, which cannot improve the connection speed between the two sewage pipes. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sewage pipe connection structure aiming at the defects and deficiencies of the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A sewage pipe connection structure includes a sewage pipe body, and also includes a left connection disk arranged at the left end of the sewage pipe body and on the circumferential side of the sewage pipe body, a right connection disk arranged at the right end of the sewage pipe body and on the circumferential side of the sewage pipe body, a plurality of connection through holes annularly and equidistantly opened on the side end face of the right connection disk, a plurality of connection insertion rods annularly and equidistantly arranged at the left end of the left connection disk and respectively in clearance fit with the connection through holes, a longitudinal connection hole opened on the upper end face of the left connection disk and communicating with the connection through holes at the lower end, a corresponding slot opened on the connection insertion rod for corresponding to the position of the longitudinal connection hole when the left connection disk abuts against the right connection disk, a clamping insertion rod that can be lifted and lowered on the right connection disk and located in the longitudinal connection hole and whose lower end is in snap connection with the corresponding slot, a matching inclined surface arranged at the lower end face of the clamping insertion rod and on the right end for driving the connection insertion rod to rise in the connection through hole when the connection insertion rod moves leftward in the connection through hole, and a driving member arranged between the upper end of the clamping insertion rod and the upper end of the right connection disk for driving the clamping insertion rod to descend in the connection through hole after the corresponding slot and the longitudinal connection hole are in corresponding positions so that the lower end of the clamping insertion rod is in snap connection with the corresponding slot.

[0006] A further improvement is that: the driving member includes a mounting plate arranged on the upper end face of the clamping insertion rod, and a tension spring arranged between the mounting plate and the right connection disk. There are two tension springs in total, and the two tension springs are located on the left and right sides of the clamping insertion rod.

[0007] Further improvement: An auxiliary inclined surface is provided on the left end surface of the connecting plug rod, and the inclination angle of the auxiliary inclined surface is the same as that of the mating inclined surface.

[0008] Further improvement: A position compensation device for laterally driving the connecting plug rod to move laterally on the left connecting plate is provided between the right end of the connecting plug rod and the left connecting plate.

[0009] Further improvement: The position compensation device includes a sliding opening formed on the left connecting plate for the right end of the connecting plug rod to move laterally on the left connecting plate, a threaded opening formed on the left connecting plate and communicating with the sliding opening, a threaded surface provided on the circumferential side of the connecting plug rod and threadedly connected to the threaded opening, and a driving head provided on the right end surface of the connecting plug rod for driving the connecting plug rod to rotate when driven by an external force. The threaded opening is located at the right end of the sliding opening, and the corresponding slot is an annular groove circumferentially provided on the connecting plug rod.

[0010] Further improvement: The driving head is an internal hexagonal head or an external hexagonal head.

[0011] Further improvement: An elastic sealing protrusion is provided on the right end surface of the sewage pipe body, and a sealing groove for cooperating with the elastic sealing protrusion is formed on the left end surface of the sewage pipe.

[0012] After adopting the above technical solution, the beneficial effects of the utility model are as follows: When it is necessary to connect two sewage pipes, the left and right ends of the two sewage pipes are respectively butted, and the sewage pipes are adjusted so that the positions of the connecting plug rod and the connecting perforation correspond. Subsequently, the connecting plug rod is respectively inserted into the connecting perforation, and the two sewage pipes are pushed closer to each other until the left connecting plate and the right connecting plate are abutted against each other. At this time, the positions of the corresponding slot and the longitudinal connecting hole correspond. The driving member drives the engaging plug rod to descend in the connecting perforation so that the lower end of the engaging plug rod is engaged and connected with the corresponding slot to limit the rightward movement of the right side of the left connecting plate, and the right connecting plate can also limit the leftward movement of the left connecting plate, thereby connecting the two sewage pipes. There is no need to connect through two flange plates and multiple bolts, and the operation is relatively simple, which can improve the connection speed between the two sewage pipes.

[0013] Further effect: When the connecting plug rod moves leftward in the connecting perforation, due to the setting of the mating inclined surface, the engaging plug rod gradually rises in the longitudinal connecting hole as the connecting plug rod moves. When the engaging plug rod rises, the tension spring is gradually stretched to generate elastic potential energy until the positions of the corresponding slot and the longitudinal connecting hole correspond. At this time, the tension spring releases the elastic potential energy to pull the mounting plate downward to drive the engaging plug rod to descend, so that the lower end of the engaging plug rod is engaged in the corresponding slot.

[0014] Further effect: When the connecting plug rod contacts the mating inclined surface, the contact area between the two is increased by the contact between the auxiliary inclined surface and the mating inclined surface, so as to improve the ascending effect of the engaging plug rod in the longitudinal opening. When two sewage pipes are connected and the left connecting plate and the right connecting plate are already in contact with each other, but the positions of the corresponding slots and longitudinal connecting holes do not correspond, the lower end of the engaging plug rod cannot be engaged with the corresponding slot, so the left connecting plate and the right connecting plate cannot be fixed. At this time, turn the driving head with a tool, drive the connecting plug rod to rotate forward in the left connecting plate, and make the connecting plug rod move leftward in the sliding opening on the left connecting plate through the cooperation of the threaded surface and the threaded opening until the positions of the corresponding jacks and the longitudinal connecting holes correspond, so that the lower end of the engaging plug rod is engaged with the corresponding slot;

[0015] If the left connecting plate and the right connecting plate are not completely in contact and the lower end of the engaging plug rod has been engaged with the corresponding slot, and the two sewage pipes are not completely sealed at this time, the engaging connection can be released by pulling the engaging plug rod upward first, and the driving head is rotated in the reverse direction with a tool to drive the connecting plug rod to rotate in the reverse direction, so that the connecting plug rod moves rightward in the sliding opening on the left connecting plate, thereby adjusting the position of the connecting plug rod on the left connecting plate until the corresponding slot can correspond to the position of the longitudinal connecting hole when the left connecting plate and the right connecting plate are in contact, which can be adjusted and compensated when there is an error in the production length or installation length of the connecting plug rod.

[0016] Further effect: When two sewage pipes are connected to each other, the elastic sealing protrusions and the sealing grooves can prevent sewage from leaking from the connection gap between the two sewage pipes, improving the sealing performance after the sewage pipes are connected.

The number of connection perforations 4 and connection insertion rods 5 corresponds to each other.

[0025] The driving member includes a mounting plate 10 provided on the upper end face of the engaging insertion rod 8 and a tension spring 11 provided between the mounting plate 10 and the right connection disk 3. There are two tension springs 11 in total, and the two tension springs 11 are located on the left and right sides of the engaging insertion rod 8.

[0026] An auxiliary inclined surface 12 is provided on the left end face of the connection insertion rod 5, and the inclination angle of the auxiliary inclined surface 12 is the same as that of the mating inclined surface 9.

[0027] A position compensation device for laterally driving the connecting plug rod 5 to move laterally on the left connecting plate 2 is provided between the right end of the connecting plug rod 5 and the left connecting plate 2.

[0028] The position compensation device includes a sliding opening 13 formed on the left connecting plate 2 for allowing the right end of the connecting plug rod 5 to move laterally on the left connecting plate 2, a threaded opening 14 formed on the left connecting plate 2 and communicating with the sliding opening 13, a threaded surface 15 provided on the circumferential side of the connecting plug rod 5 and threadedly connected to the threaded opening 14, and a driving head 16 provided on the right end face of the connecting plug rod 5 for driving the connecting plug rod 5 to rotate when driven by an external force.

[0029] The driving head 16 is an internal hexagonal head or an external hexagonal head.

[0030] An elastic sealing protrusion 17 is provided on the right end face of the sewage pipe body 1, and a sealing groove 18 for cooperating with the elastic sealing protrusion 17 is formed on the left end face of the sewage pipe.

[0031] The working principle of the present utility model: When it is necessary to connect two sewage pipes, the left and right ends of the two sewage pipes are respectively butted, and the sewage pipes are adjusted so that the positions of the connecting plug rod 5 and the connecting through hole 4 correspond. Subsequently, the connecting plug rod 5 is respectively inserted into the connecting through hole 4, and the two sewage pipes are pushed closer to each other. When the connecting plug rod 5 moves leftward in the connecting through hole 4, due to the arrangement of the cooperating inclined surface 9, the engaging plug rod 8 gradually rises in the longitudinal connecting hole 6 as the connecting plug rod 5 moves, and the tension spring 11 is gradually stretched to generate elastic potential energy when the engaging plug rod 8 rises. At this time, the positions of the corresponding slot 7 and the longitudinal connecting hole 6 correspond to each other until the left connecting plate 2 and the right connecting plate 3 are abutted against each other. At this time, the positions of the corresponding slot 7 and the longitudinal connecting hole 6 correspond to each other, and the tension spring 11 releases the elastic potential energy to pull the mounting plate 10 downward to drive the engaging plug rod 8 to descend, so that the lower end of the engaging plug rod 8 is engaged in the corresponding slot 7 to limit the rightward movement of the left connecting plate 2, and the right connecting plate 3 can also limit the leftward movement of the left connecting plate 2, thereby connecting the two sewage pipes. There is no need to connect through two flange plates and a plurality of bolts, the operation is relatively simple, and the connection speed between the two sewage pipes can be improved;

[0032] When the connecting plug rod 5 contacts the mating inclined surface 9, the contact area between the two is increased by the contact between the auxiliary inclined surface 12 and the mating inclined surface 9, so as to improve the rising effect of the engaging plug rod 8 in the longitudinal opening. When two sewage pipes are connected and the left connecting disk 2 and the right connecting disk 3 are already in contact with each other, but the positions of the corresponding slots 7 and the longitudinal connecting holes 6 do not correspond, the lower end of the engaging plug rod 8 cannot be engaged with the corresponding slot 7, so the left connecting disk 2 and the right connecting disk 3 cannot be fixed. At this time, the driving head 16 is rotated by a tool, driving the connecting plug rod 5 to rotate forward in the left connecting disk 2. Through the cooperation of the threaded surface 15 and the threaded opening 14, the connecting plug rod 5 moves leftward in the sliding opening 13 on the left connecting disk 2 until the position of the corresponding jack and the position of the longitudinal connecting hole 6 correspond, so that the lower end of the engaging plug rod 8 is engaged with the corresponding slot 7;

[0033] If the left connecting disk 2 and the right connecting disk 3 are not completely in contact and the lower end of the engaging plug rod 8 has been engaged with the corresponding slot 7, and the two sewage pipes are not completely sealed at this time, the engaging plug rod 8 can be pulled up first to release the engagement connection. The driving head 16 is rotated in the reverse direction by a tool to drive the connecting plug rod 5 to rotate in the reverse direction, so that the connecting plug rod 5 moves rightward in the sliding opening 13 on the left connecting disk 2, thereby adjusting the position of the connecting plug rod 5 on the left connecting disk 2 until the corresponding slot 7 can correspond to the position of the longitudinal connecting hole 6 when the left connecting disk 2 and the right connecting disk 3 are in contact. It can be adjusted and compensated when there is an error in the production length or installation length of the connecting plug rod 5.
