Description
Technical Field
[0001] The present application relates to the technical field of pipeline dredging devices, and in particular to a sewer pipeline dredging device. Background Art
[0002] In life, we often encounter the problem of sewer blockage, which causes trouble to people's normal life. The unblocking steel chisel is a tool used for unblocking and cleaning pipes. The unblocking steel chisel is designed to penetrate the blockage, remove obstacles in the pipe, and restore the smooth flow of the pipe.
[0003] When in use, align the unclogging end of the unclogging steel chisel with the blockage position, slowly and forcefully insert it into the pipe, and while pushing the unclogging steel chisel forward, turn the handle to drive the unclogging steel chisel to rotate to help the unclogging steel chisel penetrate and entangle the blockage, then slowly pull out the unclogging steel chisel to clear the blockage in the pipe at the same time.
[0004] However, the method of rotating the dredging steel bar by manually holding the handle is rather tiring, and for thicker pipes or serious blockages, a thicker dredging steel bar may need to be used, and manual rotation is even more tiring and inconvenient, so further improvement is needed. Utility Model Content
[0005] In order to reduce the labor intensity of the staff, the present application provides a sewer pipe dredger.

When the first joint and the second joint need to be disassembled, the limiting column is driven to slide and retract into the receiving hole through the unlocking member, so that the limiting column is disengaged from the first limiting hole. After the sliding restriction on the clamping protrusion is released, the first joint or the second joint can be radially slid.

[0017] Preferably, the second joint is detachably connected to the connecting rod.

[0022] By adopting the above technical solution, the end of the connecting rod with the limiting rod is first axially inserted into the mounting hole, and then the connecting rod is moved radially so that the limiting rod on the connecting rod is inserted into the second limiting hole. Then, a lock head is slidably mounted from the other end of the connecting rod, and the lock head is moved so that the end of the lock head abuts against the lower part of the mounting hole. Then, the lock head is rotated to lock the lock head to the second joint, thereby fixing the connecting rod and the second joint.

[0033] The receiving hole 52 is provided with an elastic member that forces the limiting column 53 to slide and protrude from the end surface of the clamping protrusion 51 under normal conditions. Specifically, the elastic member is a spring 54 built into the receiving hole 52, one end of the spring 54 is fixedly connected to the inner wall of the receiving hole 52, and the other end of the spring 54 is fixedly connected to the end surface of the limiting column 53.
