Description

Technical Field

[0001] The utility model relates to the technical field of galvanized steel pipes, in particular to a novel galvanized steel pipe. Background Art

[0002] Galvanized steel pipe is a kind of steel pipe with a special surface treatment. Its characteristic is that a layer of zinc is coated on the surface of ordinary steel pipe. This zinc layer can effectively prevent the steel pipe from being oxidized and corroded, thereby greatly improving the corrosion resistance and service life of the steel pipe. Galvanized steel pipe is mainly used to transport fluids such as water, gas, and oil. It is widely used in many fields such as construction, machinery, coal mining, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, and prospecting machinery.

[0003] At present, some galvanized steel pipes on the market are connected by threaded connection, which requires opening threads on the outer surface of the steel pipe and the inner surface of the pipe joint, then applying thread sealant on the end of the steel pipe, then aligning the pipe joint with the end of the steel pipe, rotating the pipe joint so that the threads engage with each other, and finally using a wrench or other tools to tighten the pipe joint to make the connection tight. However, this operation method is troublesome, time-consuming and labor-intensive, especially when connecting multiple pipe sections, it has high operating requirements for workers and is not practical. For this reason, a new type of galvanized steel pipe is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a new type of galvanized steel pipe to solve the problems raised in the above background technology.

[0005] The cam is an assembly made of a first piece and a second piece, and the cam is connected to the first piece and a second piece by a threaded connection.

[0006] As a further preferred embodiment of the present technical solution: a sealing ring is bonded between the first pipe section and the second pipe section.

[0007] As a further preferred embodiment of the present technical solution: the outer wall of the first pipe segment is fixedly connected with two positioning blocks, the outer wall of the second pipe segment is fixedly connected with two mounting blocks, the left side wall of the mounting block is fixedly connected with a positioning pin, and the outer wall of the positioning pin is slidably connected with the inner wall of the positioning block.

[0008] As a further preferred embodiment of the present technical solution: brackets are welded to the lower surfaces of the first pipe segment and the second pipe segment.

[0009] As a further preferred embodiment of the technical solution: one end of the sliding rod away from the force-bearing plate is fixedly connected with a circular plate.

[0010] As a further preferred embodiment of the present technical solution: a mounting ring is fixedly connected to one side of the first pipe section and the second pipe section which are away from each other.

[0011] As a further preferred embodiment of the present technical solution: the outer side wall of the mounting ring is evenly provided with mounting holes.

[0012] As a further preferred embodiment of the present technical solution: the outer side walls of the first pipe section and the second pipe section are both plated with a zinc layer.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model is that the two movable plates are respectively clamped in the sliding grooves on the two force-bearing plates, and the push plate is pushed, and the push plate drives the two rectangular plates to move, and the two rectangular plates drive the two movable plates to move away from each other. At this time, the force-bearing plates squeeze the springs, and the slide rods slide along the inner side walls of the fixed plates. When the two movable plates are close to each other, they move to the inner side wall opening of the connecting plate, and the push plate is released. The elastic force of the spring drives the two force-bearing plates to approach each other, and the two force-bearing plates drive the movable plates to slide toward the inner side walls of the fixed plates. Under the action of the spring, the two movable plates are tightly clamped on the inner side walls of the two fixed plates, so as to complete the connection of the first pipe section and the second pipe section. The connection method is relatively simple, saves time and labor, has low operation requirements for workers, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
