[0002] Steel pipe refers to the steel material with hollow section, and the length is much larger than the diameter or the circumference. According to the section shape, it is divided into round, square, rectangular and special-shaped steel pipes. According to the material, it is divided into carbon structural steel pipe, low alloy structural steel pipe, alloy steel pipe and composite steel pipe. According to the use, it is divided into conveying pipe, engineering structure, hot work equipment, petroleum and chemical industry, machinery manufacturing, geological drilling, high pressure equipment and so on. According to the production process, it is divided into seamless steel pipe and welded steel pipe.
[0003] At present, when the square steel pipe is used, in order to prolong the use length of the steel pipe, two square steel pipes are connected, and in the prior art, the connection is usually realized by welding, and after connection, it is not easy to separate, so that when the steel pipe is replaced, the connected steel pipes need to be disassembled together, which is inconvenient.
[0004] Therefore, it is necessary to provide a square steel pipe to solve the above problems. TECHNICAL SOLUTION
[0005] The utility model discloses a square steel pipe to solve the problems in the above background.
[0006] In order to achieve the above object, the utility model provides the following technical scheme: a square steel pipe, including steel pipe body, the one end outside of steel pipe body is provided with the connecting pipe, the four around inner walls of connecting pipe all are seted up with two recesss, and recess is connected with spring, the other end of spring is connected with the plug rod, the front side of plug rod is set as the inclined plane, the top of plug rod is connected with the pull rod, the other end of pull rod is connected with the pull plate, the four around outside of connecting pipe all are seted up with the storage groove corresponding with pull plate, the other end outside of steel pipe body is seted up with a plurality of insertion slot corresponding with plug rod.
[0007] Preferably, the four around inner walls of the connecting pipe are connected with T-shaped sliding blocks, and the four around outer sides of the steel pipe body are provided with T-shaped sliding grooves corresponding to the T-shaped sliding blocks.
[0008] Preferably, the pull plate is provided with a recess handle away from the pull rod.
[0009] Preferably, the inner wall of the connecting pipe is provided with two sealing grooves, and the sealing grooves are provided with sealing pads, and the specific material of the sealing pad is rubber.
[0010] The utility model discloses a square steel pipe to solve the problems in the above background.
[0011] By pulling the connecting tube, it slides on the steel pipe body, extending a portion of the connecting tube. The slotted end of another steel pipe body is inserted into the extended connecting tube, and the inclined surface of the insert rod is pressed, causing the insert rod to slide within the groove and compressing the spring. This causes the spring to deform, and when the insert rod aligns with the slot, the spring pushes the insert rod into the slot, thus connecting the two steel pipe bodies. Conversely, by pulling the pull plate, which pulls the pull rod, the insert rod is pulled out of the slot, allowing for easy disassembly and assembly of the two steel pipe bodies.
