[0023] The utility model embodiment discloses a stainless steel pipe with a reinforcement structure. Figure 1-3 As shown, it includes a pipe fitting body 1, and reinforcement structures are installed at both ends of the pipe fitting body 1;

[0024] The reinforcement structure includes:

[0025] A reinforcement sleeve 2, a fixing groove 201 is provided on the side of the reinforcement sleeve 2, the end of the pipe body 1 is plugged into the inner wall of the fixing groove 201, a plurality of limiting cavities 202 are provided inside the reinforcement sleeve 2, the plurality of limiting cavities 202 are all connected to the inside of the fixing groove 201, and the inner walls of the plurality of limiting cavities 202 are all slidably connected to limiting blocks 203;

[0026] The driving assembly is disposed inside the reinforcement sleeve 2 , and is used to drive the plurality of limit blocks 203 to move toward the fixing groove 201 at the same time.

[0027] During use, first insert the end of the pipe body 1 into the fixing groove 201 on the side of the reinforcement sleeve 2, and then use the driving assembly to drive multiple limit blocks 203 to move toward the fixing groove 201 at the same time, until the multiple limit blocks 203 effectively squeeze and fix the pipe body 1 in the fixing groove 201. At this time, the end of the pipe body 1 and the outer wall and the inner wall are tightly fitted with the reinforcement sleeve 2, so that the reinforcement sleeve 2 can effectively protect the pipe body 1 and prevent the pipe body 1 from being dented due to collision during transportation.

[0028] Particularly disclosed, the drive assembly comprises:

[0029] The movable plate 3 and the other side of the reinforcing sleeve 2 are provided with an empty groove, and the movable plate 3 is slidably connected to the inner wall of the empty groove;

[0030] Multiple transmission cavities 301 are provided, and the multiple transmission cavities 301 are all opened inside the reinforcement sleeve 2, and the multiple transmission cavities 301 are respectively connected with the multiple limit cavities 202, and the transmission blocks 302 are slidably connected on the inner wall of the transmission cavity 301, and the ends of the transmission blocks 302 extend toward the limit cavity 202 and are fixedly connected with the limit blocks 203, and the movable plate 3 is transmission-connected with the multiple transmission blocks 302.

[0031] The movable plate 3 is pushed to slide in the empty groove. Since the movable plate 3 is connected to the multiple transmission blocks 302, the multiple transmission blocks 302 can be moved in the multiple limit cavities 202 respectively, and the limit blocks 203 are driven to slide in the limit cavities 202 until the limit blocks 203 are tightly against the end of the pipe body 1, so that the pipe body 1 can be fixed.

[0032] It is particularly disclosed that an extrusion block 303 is slidably connected inside the reinforcement sleeve 2, and an inclined surface is provided at the end of the transmission block 302. The end of the extrusion block 303 fits with the inclined surface of the end of the transmission block 302, and the other end of the extrusion block 303 is fixedly connected with an extrusion strip 305, and the end of the extrusion strip 305 abuts against the outer side of the movable plate 3.

[0033] When the moving plate 3 slides, it can push the extrusion bar 305 to slide toward the transmission cavity 301, thereby driving the extrusion block 303 to move accordingly. The end of the extrusion block 303 fits with the inclined surface of the end of the transmission block 302, which can push the transmission block 302 to move accordingly.

[0034] Furthermore, a plurality of positioning grooves 306 are formed on the inner wall of the empty groove, and a plurality of positioning blocks 307 are fixedly connected to the outer side of the movable plate 3 , and the plurality of positioning blocks 307 are slidably connected to the inner walls of the plurality of positioning grooves 306 .

[0037] It is particularly disclosed that the outer side of the screw rod 308 is threadedly connected with a threaded sleeve 309 , and the end of the threaded sleeve 309 is rotatably connected to the side surface of the moving plate 3 .

[0038] During the process of rotating the threaded sleeve 309, the threaded sleeve 309 is threadedly connected to the outer side of the screw rod 308, so that the threaded sleeve 309 can rotate. At the same time, the end of the threaded sleeve 309 is rotationally connected to the side of the movable plate 3, which can push the movable plate 3 to slide in the empty groove.

[0039] It is particularly disclosed that a return spring 304 is fixedly connected between the inner wall of the limiting cavity 202 and the outer side of the limiting block 203 .

[0040] When the transmission block 302 is no longer squeezed by the squeezing block 303, the reset spring 304 can drive the limit block 203 to reset, thereby preventing the limit block 203 from being in the fixing groove 201, causing the end of the pipe body 1 to be unable to be inserted into the fixing groove 201.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
