Technical Field

[0001] The utility model relates to the technical field of steel pipes, in particular to a corrosion-resistant seamless steel pipe. Background Art

[0002] A steel pipe made by punching a whole round steel bar without welds on the surface is called a seamless steel pipe. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and jacking pipes;

[0003] The reference patent name is: A corrosion-resistant seamless steel pipe (authorization announcement number: CN 220037709 U) includes a pipe wall mechanism, an interface mechanism is fixedly arranged on one side of the pipe wall mechanism, and a socket mechanism is fixedly arranged on the other side of the pipe wall mechanism, and the interface mechanism includes a first fixing ring, and a sealing ring is fixedly arranged on the outer surface of one side of the first fixing ring; in the utility model, the pipe wall mechanism is composed of a multi-layer structure, so that the steel pipe structure is more stable, the interface mechanism and the socket mechanism are connected to each other, so that the steel pipe can be connected, the first fixing ring of the interface mechanism connects the entire interface mechanism, and the sealing ring makes the interface mechanism and the socket mechanism have excellent air tightness after being connected, and there are clamping teeth on the four connecting plates on the first fixing ring. When the interface mechanism is inserted into the socket mechanism, the clamping teeth on the upper end of the connecting plate are clamped into the clamping groove of the socket mechanism, so that the interface mechanism and the socket mechanism can be fixedly connected;

[0004] Although this patent can achieve the effect of connecting and disassembling steel pipes through the socket mechanism, it is necessary to press the pressing plate to unlock it during the disassembly process. Due to its relatively hard material, it requires a lot of manual force to press the pressing plate, resulting in poor pressing effect and more troublesome operation.

[0005] Therefore, it is necessary to provide a new corrosion-resistant seamless steel pipe to solve the above technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a corrosion-resistant seamless steel pipe.

[0007] The utility model provides a corrosion-resistant seamless steel pipe, comprising a body, a pipeline is installed on the inner side of the body, and a connecting mechanism for connecting the pipeline is installed on the inner side of the body, and the connecting mechanism comprises:

[0008] A connecting assembly is installed on the inner side of the body, including slide grooves equidistantly arranged on the inner side of the body, a clamping strip is equidistantly fixed on one side of the pipe close to the body, the clamping strip is slidably connected to the inner side of the slide groove, and a clamping assembly for clamping the body is installed on the outer wall of the clamping strip;

[0009] The unlocking component is installed on the outer wall of the body and is used to loosen the connection between the body and the pipeline.

[0010] Preferably, the snap-on assembly includes a slot opened on the outer wall of the card strip, a first spring is fixed on the inner side of the slot, a card block is fixed on the top of the first spring, the card block is slidably connected to the inner side of the slot, a card hole is opened on the inner side of the slide groove, and the card hole is snap-connected to the outer wall of the card block.

[0011] Preferably, the unlocking assembly includes unlocking holes equidistantly opened on the outer wall of the main body, a sliding rod is slidably connected to the inner side of the unlocking hole, the lower end of the sliding rod extends to the inner side of the card hole, an unlocking plate is fixed to the bottom of the sliding rod, a second spring is fixed to the outer wall of the unlocking plate, and the other end of the second spring is fixed to the inner side of the card hole.

[0012] Preferably, a button is fixed on the top of the slide rod, and an anti-slip pattern is fixed on the outer wall of the button.

[0013] Preferably, the bottom of the unlocking plate is in compression contact with the outer wall of the blocking block.

[0014] Preferably, a sealing ring is fixed on the inner side of the body.

[0015] Compared with the related art, the corrosion-resistant seamless steel pipe provided by the utility model has the following beneficial effects:

[0016] 1. Due to its hard material, it takes a lot of effort to press the pressing plate, resulting in poor pressing effect and troublesome operation. Unlocking by pressing the button through the connecting mechanism usually only requires a light press with a finger, which is very easy to operate. However, unlocking by pressing the pressing plate may require greater force, or even the use of the entire palm or arm, which is relatively complicated.

[0017] 2. In addition, button unlocking can achieve more precise control, because the finger pressing action can very accurately control the start and end of unlocking. In contrast, pressing the pressing plate may cause the unlocking to be unsmooth or fail due to uneven force distribution or difficulty in accurately controlling the force.
