Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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. Example

[0027] A stainless steel tube that is easy to splice and seal comprises an inner tube body 1, wherein an inner support block 2 is arranged inside the inner tube body 1, and the two ends thereof are respectively fixedly connected with an end block 14 and an end block 2 16, wherein the end block 14 is fixedly connected with a plug 4 on the side away from the inner support block 2, and the top and bottom of the plug 4 are fixedly connected with an insert block 5, and the end block 2 16 is provided with a socket 3 matched with the plug 4 on the side away from the inner support block 2, and the top and bottom of the inner cavity of the socket 3 are provided with a slot 6 matched with the insert block 5, and one side of the inner cavity of the slot 6 is provided with a card slot 7 matched with the insert block 5, and the surfaces of the inner support block 2, the end block 14 and the end block 2 16 are fixedly connected with reinforcing plates 8 distributed in a triangular array.

[0028] The specific usage process is as follows: first, align the two steel pipes end to end, and also align the plug 4 with the socket 3, and insert the plug 4 into the socket 3, and the plug block 5 will also be inserted into the corresponding slot 6. After the plug block 5 is inserted into the slot 6, the plug block 5 will first contact the stop block 12 and squeeze the stop block 12. Specifically, the stop block 12 is provided with an inclined surface on the side facing the slot 6. When the plug block 5 is inserted into the slot 6, it will pass through the inclined surface, thereby squeezing the stop block 12 into the inner cavity of the sliding groove 11, and squeezing the spring 13 at the same time, until the plug block 5 is completely entered into the slot 6, and then the plug block 5 is rotated into the card slot 7. Under the action of the spring 13, the stop block 12 pops out of the inner cavity of the sliding groove 11 and presses against the plug block 5, thereby limiting the plug block 5. The function is to limit the random movement of the plug block 5, ensure the firmness and stability of the steel pipe after connection, and provide convenience for users. That is to say, after the plug block 5 is fully inserted into the slot 6, the user rotates the steel pipe, and then the reinforcing plate 8 located in the steel pipe will also rotate accordingly, and then the three reinforcing plates 8 will drive the inner support block 2, the end block 14 and the end block 2 16 to rotate, and at the same time, the plug 4 installed on the end block 14 will also rotate accordingly, and the plug block 5 will also rotate with the plug 4. Finally, under the control of the user, the plug block 5 is inserted into the corresponding card slot 1 7, and will also be restricted by the block 12 to be positioned in the card slot 1 7, so that the steel pipe will not move easily after docking, thereby ensuring the tightness of the steel pipe after splicing, and the reinforcing plate 8 can also be provided from the inside for The steel pipe provides support, improves the strength of the steel pipe itself, and prolongs the service life of the steel pipe. When the steel pipes are butt-jointed, the end of the inner pipe body 1 will be inserted into the inside of the outer pipe body 10, increasing the contact area of ​​the steel pipe butt joint and improving the firmness of the steel pipe after butt joint. The second clamping groove 15 is formed by the inner wall of the outer pipe body 10 and the end of the inner pipe body 1, and the second clamping groove 15 and the end of the inner pipe body 1 provided with the embedding groove 9 are adapted to each other and can be plugged into each other, so that the two steel pipes can have better tightness and stability after butt joint, which provides convenience for users. The embedding groove 9 is used to install the sealing ring, and can limit the sealing ring to avoid displacement of the sealing ring, thereby ensuring the sealing performance when the steel pipes are butt-jointed, which provides convenience for users. The slopes of the two conical inclined surfaces on the end block 14 and the end block 2 16 are distributed in opposite directions, which can reduce the obstruction to the fluid when the fluid passes through, reduce the impact force of the fluid on the steel pipe, reduce the damage to the steel pipe, extend the service life of the steel pipe, and ensure the smooth passage of the fluid in the steel pipe. On the basis of convenient docking, it is also convenient for users to disassemble. During disassembly, rotate any steel pipe in the opposite direction, and the other steel pipe does not move. At this time, the plug 5 can be moved out of the slot 1 7, and then the user separates the steel pipe, the plug 5 will be moved out of the corresponding slot 6, and the plug 4 will also be moved out of the socket 3, and the block 12 will be squeezed into the sliding groove 11 by the plug 5 again, and then it will return to its original position under the action of the spring 13, thereby providing convenience for the user's work.

[0029] Therefore, a one-insert-one-rotate docking structure design is adopted. When splicing steel pipes, users only need to align the head and tail ends of the steel pipe, plug them in, and then rotate them to complete the splicing of the steel pipes. This can not only ensure the tightness, firmness and stability after docking, but also increase the speed of users assembling steel pipes, save time, improve work efficiency, and provide convenience for users' work.

[0030] A sliding groove 11 is provided on the side of the inner cavity of the slot 6 away from the card slot 7, and a stop block 12 adapted to the plug block 5 is slidably installed in the inner cavity of the sliding groove 11. One end of the stop block 12 is fixedly connected to a spring 13, and the end of the spring 13 away from the stop block 12 is fixedly connected to the inner wall of the sliding groove 11.

[0031] Specifically, the sliding groove 11, the stopper 12 and the spring 13 are arranged in such a way that the stopper 12 is provided with an inclined surface on the side facing the slot 6. When the plug 5 is inserted into the slot 6, it will pass through the inclined surface, thereby squeezing the stopper 12 toward the inner cavity of the sliding groove 11 and squeezing the spring 13 at the same time until the plug 5 is completely inserted into the slot 6. Then, after the plug 5 is rotated into the card slot 7, under the action of the spring 13, the stopper 12 pops out of the inner cavity of the sliding groove 11 and presses against the plug 5, thereby limiting the plug 5 and restricting the random movement of the plug 5, thereby ensuring the firmness and stability of the steel pipe after connection, and providing convenience for users.

[0032] The outer tube body 10 is fixedly connected to the surface of the inner tube body 1 , and a second clamping groove 15 is formed between the end of the inner tube body 1 and the inner wall of the outer tube body 10 .

[0033] Specifically, the outer tube body 10 and the second card slot 15 are arranged such that the second card slot 15 is formed by the inner wall of the outer tube body 10 and the end of the inner tube body 1, and the second card slot 15 and one end of the inner tube body 1 on which the embedding groove 9 is arranged are adapted to each other and can be plugged into each other, so that the two steel tubes can have better tightness and stability after docking, providing convenience for users.

[0034] An embedding groove 9 is provided on one side of the surface of the inner tube body 1 , and the embedding groove 9 is located between the outer wall of the inner tube body 1 and the end of the outer tube body 10 .

[0035] Specifically, the embedded groove 9 is used to install the sealing ring, and can limit the sealing ring to avoid displacement of the sealing ring, thereby ensuring the sealing performance when the steel pipes are butt-jointed, providing convenience for users.

[0036] A through hole 17 is formed on one side of the plug 4 , and the through hole 17 is connected to the inner cavity of the end block 14 , the inner support block 2 and the jack 3 .

[0037] Specifically, the through hole 17 is connected to the end block 14, the inner support block 2 and the socket 3, so that the center of the steel pipe can also be used for fluid flow, which greatly reduces the resistance to the flow of fluid, ensures smooth flow of fluid, and provides convenience for users' work.

[0038] The surfaces of the end block 1 14 and the end block 2 16 are both provided with conical inclined surfaces, and the two conical inclined surfaces are distributed facing each other.

[0039] Specifically, the setting of the conical slope, with the slopes of the two conical slopes distributed towards each other, can reduce the obstruction to the fluid when the fluid passes through, reduce the impact force of the fluid on the steel pipe, reduce the damage to the steel pipe, extend the service life of the steel pipe, and ensure the smooth passage of the fluid in the steel pipe.
