Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figure 1-5As shown, this utility model discloses a pressure-resistant stainless steel pipe 1, including a steel pipe 1, flanges A2 and B3 respectively fixedly installed on the front and rear sides of the steel pipe 1, and a reinforcing assembly on the steel pipe 1. The reinforcing assembly includes an installation ring 4, a retaining ring A5 and a retaining ring B6 fixedly installed on the rear side of flange A2 and the front side of flange B3, several reinforcing rods 7, several bolts 8, and reinforcing plates A9 and B10 detachably installed inside the steel pipe 1. Several installation grooves 11 matching the reinforcing rods 7 are opened on the outer wall of the installation ring 4. The reinforcing rods 7 are inserted into the installation grooves 11 and abut against the steel pipe 1 and the installation ring 4. The retaining rings A5 and B6 are respectively sleeved on the upper and lower sides of the installation ring 4. Fixing rings 12 are fixedly installed on the left and right sides of the retaining rings A5 and B6. The fixing rings 12 on the retaining rings A5 and B6 are fixedly connected by bolts 8. The reinforcing plates A9 and B10 are arranged in a cross shape. In use, the reinforcing rod 7 is inserted into the mounting groove 11 and abuts against the steel pipe 1 and mounting ring 4. The number of reinforcing rods 7 can be increased or decreased as needed. An elastic collar 20 is fitted onto the outside of the reinforcing rod 7 to pre-fix it and prevent it from falling out of the mounting groove 11. Clamping rings A5 and B6 are respectively fitted onto the upper and lower sides of the mounting ring 4, making them contact and connect with the mounting ring 4 and the reinforcing rod 7. The fixing rings 12 on clamping ring A5 and B6 are fixedly connected by bolts 8, tightening them onto the mounting ring 4, thus fixing the reinforcing rod 7 within the mounting groove 11 and completely securing it, thus reinforcing the steel pipe 1 from the outside. Reinforcing plates A9 and B10 are then inserted into the mounting groove 11. Slot A15 and slot B16 are connected in contact with each other. At this time, reinforcing plates A9 and B10 are arranged in a cross shape. Reinforcing plates A9 and B10 are placed inside the steel pipe 1 and connected to the steel pipe 1. The clamping ring 13 is screwed into the steel pipe 1 and connected to the steel pipe 1 by threads. The clamping ring 13 is tightened to fix it to the reinforcing plates A9 and B10, thereby fixing the reinforcing plates A9 and B10 inside the steel pipe 1, which plays a role in reinforcing the steel pipe 1 from the inside. In summary, this utility model reinforces the steel pipe 1 from both the outside and the inside of the steel pipe 1 at the same time, which has the beneficial effect of strong compressive strength. It solves the problem that the traditional stainless steel pipe 1 has relatively poor compressive strength and is prone to bending and deformation when subjected to external pressure, which makes the stainless steel pipe 1 unusable.

[0021] Preferably, the reinforcement assembly further includes clamping rings 13 located on the front and rear sides of the reinforcement plate A9. Both the inner side of the steel pipe 1 and the outer side of the clamping rings 13 are threaded. After being screwed into the steel pipe 1, the clamping rings 13 are fixedly connected to the reinforcement plate A9 and the reinforcement plate B10. Since both the inner side of the steel pipe 1 and the outer side of the clamping rings 13 are threaded, screwing the clamping rings 13 into the steel pipe 1 and tightening them will fix the clamping rings 13 to the reinforcement plate A9 and the reinforcement plate B10, thus facilitating the installation and removal of the clamping rings 13, and consequently facilitating the installation and removal of the reinforcement plate A9 and the reinforcement plate B10.

[0022] Preferably, an elastic ring 14 is fixedly provided on the side of the clamping ring 13 facing the reinforcing plate A9. After the clamping ring 13 is screwed into the steel pipe 1, the elastic ring 14 is fixedly positioned between the clamping ring 13 and the reinforcing plate A9 and the reinforcing plate B10. Since the elastic ring 14 is fixedly provided on the side of the clamping ring 13 facing the reinforcing plate A9, after the clamping ring 13 is screwed into the steel pipe 1 and tightened, the elastic ring 14 is fixedly positioned between the clamping ring 13 and the reinforcing plate A9 and the reinforcing plate B10, which plays a role in applying a certain elastic force to the clamping ring 13 and preventing the clamping ring 13 from loosening.

[0023] Preferably, a slot A15 is provided on the rear side wall of the reinforcing plate A9, and a slot B16 is provided on the front side wall of the reinforcing plate B10. The reinforcing plates A9 and B10 are inserted into slots A15 and B16 respectively, and then abut against each other. Since the reinforcing plates A9 and B10 are inserted into slots A15 and B16 respectively and then abut against each other, they are arranged in a cross shape, which enhances the supporting force.

[0024] Preferably, a positioning groove 17 is provided on the outer wall of the mounting ring 4, and positioning strips 18 are fixedly provided on the inner sides of both the retaining ring A5 and the retaining ring B6. The positioning strips 18 are inserted into the positioning groove 17 and abut against the mounting ring 4. Since the positioning strips 18 are inserted into the positioning groove 17 and abut against the mounting ring 4, they facilitate the positioning and installation of the retaining rings A5 and B6.

[0025] Preferably, a magnet 19 is fixedly installed inside the positioning groove 17, and an iron piece is fixedly installed on the outer wall of the positioning strip 18. After the positioning strip 18 is inserted into the positioning groove 17, the iron piece on the outer wall of the positioning strip 18 is magnetically attracted to the magnet 19. Since the iron piece on the outer wall of the positioning strip 18 is magnetically attracted to the magnet 19 after the positioning strip 18 is inserted into the positioning groove 17, it plays a pre-fixing role, which facilitates the subsequent installation of the bolts 8.

[0026] Preferably, the reinforcing component further includes an elastic collar 20, which is sleeved on the outside of the reinforcing rod 7. Since the elastic collar 20 is sleeved on the outside of the reinforcing rod 7, it serves to pre-fix the reinforcing rod 7, preventing it from falling out of the mounting groove 11.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
