[0005] Although the existing technology can quickly complete the docking of adjacent steel pipes, after the docking, when the steel pipe body needs to be disassembled after long-term use, there is no auxiliary disassembly structure, which will affect the operation of the staff and bring unnecessary trouble to the operator.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original seamless steel pipe. Utility Model Content

[0007] The utility model aims to provide a seamless steel pipe that is convenient for butt jointing, so as to solve the problem that the structure proposed in the above background technology does not have auxiliary disassembly, which will affect the operation of the staff and bring unnecessary trouble to the operator.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a seamless steel pipe convenient for butt joint use, comprising a seamless steel pipe body, an upper connecting block is fixedly connected to the upper surface of the seamless steel pipe body, and a butt joint pipe is fixedly connected to the right end of the seamless steel pipe body, and the outer ring diameter of the butt joint pipe is equal to the inner ring diameter of the seamless steel pipe body;

[0011] A connecting plate is fixedly connected to the upper surface of the fixing block, and a clamping block is slidably arranged inside the connecting plate.

[0012] Preferably, a long pin corresponding to the through hole is fixedly connected to the right side surface of the upper connecting block, and a clamping groove corresponding to the clamping block is formed on the upper surface of the long pin.

[0013] Preferably, the left side surface of the card block is inclined, the card block passes through the interior of the fixed block, and an auxiliary plate is fixedly connected to the surface of the card block.

[0014] Preferably, the connecting plate is an inverted "U" shape when viewed from the left, and a second spring having an elastic reset function is fixedly connected to the upper surface of the auxiliary plate, and the other side of the second spring is fixedly connected to the inner wall of the connecting plate.

[0015] Preferably, the upper surface of the block is spherical.

[0016] Preferably, a limiting rod is fixedly connected to the left surface of the fixing block, and the limiting rod is symmetrically distributed about the center of the fixing block, and positioning holes corresponding to the limiting rods are opened on the surface of the upper connecting block.

[0017] Preferably, a force-bearing plate is slidably provided on the surface of the limiting rod, and a first spring having an elastic reset function is fixedly connected to the surface of the force-bearing plate, and the other side of the first spring is fixedly connected to the left side surface of the fixed block.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the seamless steel pipe which is convenient for butt jointing adopts a new structural design, and its specific contents are as follows:

[0019] (1) When the seamless steel pipe is convenient for docking, when the adjacent seamless steel pipe bodies need to be docked, the long pin on the surface of the upper connecting block is inserted into the through hole on the surface of the fixed block. At this time, the long pin will push the clamping block, so that the clamping block drives the auxiliary plate to squeeze the second spring. When the adjacent seamless steel pipe bodies are in contact, the clamping block and the clamping groove are in the same horizontal direction. At this time, the clamping block enters the clamping groove under the action of the second spring and the auxiliary plate, and then the adjacent seamless steel pipe bodies are docked. The operation process is fast and convenient;

[0020] Furthermore, the butt joint at the end of the seamless steel pipe body ensures that there will be no gap when the adjacent seamless steel pipe bodies are butt jointed, and thus no material leakage will occur, thus ensuring the normal operation of the seamless steel pipe body;

[0021] (2) When the seamless steel pipe that is convenient for butt connection needs to be separated from the adjacent seamless steel pipe bodies, the clamping block is directly pulled, and the end of the clamping block is moved out of the clamping slot, so that the fixed block and the adjacent upper connecting block are not in a clamping state. At this time, the adjacent seamless steel pipe bodies can be separated, the operation process is fast and convenient, and the operator does not need to carry additional disassembly and assembly tools, thereby improving work efficiency;

[0022] Furthermore, when the adjacent seamless steel pipe bodies are butted, the limit rod will enter the interior of the positioning hole on the surface of the upper connecting block, and the right side of the upper connecting block will push the force plate, and then the first spring will be squeezed, that is, when the adjacent seamless steel pipe bodies are in a butt state, the first spring is always in a squeezed state, and then when the upper connecting block and the fixed block are not in a clamping state, the first spring will push the force plate to separate the adjacent seamless steel pipe bodies, and then the first spring plays a role in assisting disassembly, simplifying the operator's work;

[0023] (3) The limit rod and the positioning hole of the seamless steel pipe that is convenient for butt connection not only play a positioning role during operation, but also increase the stability of adjacent seamless steel pipe bodies when butt connection, so that the adjacent seamless steel pipe bodies can remain stable when transporting materials.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Embodiment 1: By providing the clamping block 11 and the clamping slot 5, adjacent seamless steel pipe bodies 1 can be quickly connected, such as Figure 1-Figure 6 As shown:

[0033] It comprises a seamless steel pipe body 1, an upper connecting block 2 is fixedly connected to the upper surface of the seamless steel pipe body 1, and a butt pipe 3 is fixedly connected to the right end of the seamless steel pipe body 1, and the outer ring diameter of the butt pipe 3 is equal to the inner ring diameter of the seamless steel pipe body 1;

[0034] Also includes:

[0035] A fixed block 6 is fixedly connected to the upper surface of the left side of the seamless steel pipe body 1, and a through hole 7 is opened on the surface of the fixed block 6; a connecting plate 12 is fixedly connected to the upper surface of the fixed block 6, and a clamping block 11 is slidably arranged inside the connecting plate 12.

[0036] The right side surface of the upper connecting block 2 is fixedly connected with a long pin 4 corresponding to the through hole 7, and the upper surface of the long pin 4 is provided with a card slot 5 corresponding to the card block 11, the left side surface of the card block 11 is inclined, and the card block 11 passes through the interior of the fixed block 6, and the surface of the card block 11 is fixedly connected with an auxiliary plate 13, the left view of the connecting plate 12 is an inverted "U" shape, and the upper surface of the auxiliary plate 13 is fixedly connected with a second spring 14 that plays an elastic reset role, and the other side of the second spring 14 is fixedly connected to the inner wall of the connecting plate 12.

[0037] When it is necessary to butt-join the adjacent seamless steel pipe bodies 1, the long pin 4 on the surface of the upper connecting block 2 is inserted into the through hole 7 on the surface of the fixed block 6. At this time, the long pin 4 will push the clamping block 11, and the clamping block 11 will slide inside the connecting plate 12. At the same time, the clamping block 11 drives the auxiliary plate 13 to squeeze the second spring 14. When the adjacent seamless steel pipe bodies 1 are in contact, the clamping block 11 and the clamping groove 5 are in the same horizontal direction. At this time, the clamping block 11 enters the clamping groove 5 under the action of the second spring 14 and the auxiliary plate 13, and then the adjacent seamless steel pipe bodies 1 are butt-jointed. The operation process is quick and convenient, and the butt-jointed tube 3 at the end of the seamless steel pipe body 1 ensures that there will be no gap when the adjacent seamless steel pipe bodies 1 are butt-jointed, and thus no material leakage will occur, thereby ensuring the normal operation of the seamless steel pipe body 1.

[0038] Embodiment 2: Different from Embodiment 1, when adjacent seamless steel pipe bodies 1 need to be separated, they can be quickly separated by the clamping block 11, such as Figure 2 and Figure 3 As shown:

[0039] The upper surface of the block 11 is spherical.

[0040] When it is necessary to separate the adjacent seamless steel pipe bodies 1, directly pull the clamping block 11. At this time, the end of the clamping block 11 moves out of the clamping slot 5, so that the fixing block 6 and the adjacent upper connecting block 2 are not in a clamping state.

The operation process is quick and convenient, and the operator does not need to carry additional disassembly and assembly tools, thereby improving work efficiency.

[0043] When the adjacent seamless steel pipe bodies 1 are butt-jointed, the limiting rod 8 will enter into the interior of the positioning hole 15 on the surface of the upper connecting block 2. At this time, the right side of the upper connecting block 2 will push the force plate 9, and then the first spring 10 will be squeezed, that is, when the adjacent seamless steel pipe bodies 1 are in a butt-jointed state, the first spring 10 is always in a squeezed state, and then when the upper connecting block 2 and the fixing block 6 are not in an engaged state, the first spring 10 will push the force plate 9 to separate the adjacent seamless steel pipe bodies 1, and then the first spring 10 plays a role in assisting disassembly, thereby simplifying the operator's work.
