[0028] The following is combined with Figure 1-4 The utility model is described in further detail.

[0029] The embodiment of the utility model discloses an all-aluminum thermal insulation sheath pipe which is easy to splice.

[0030] Reference Figure 1 and Figure 2, an all-aluminum thermal insulation sheath pipe that is easy to splice, including a sleeve 1, a sleeve 2 is plugged into the outside of the sleeve 1, the top of the sleeve 1 and the sleeve 2 are fixedly connected with a plug-in block 3, the bottom ends of the sleeve 1 and the sleeve 2 are provided with a plug-in groove 4, the back of the sleeve 1 is fixedly connected with a fixing plate 1 5, the side of the sleeve 2 2 away from the sleeve 1 is fixedly connected with a fixing plate 2 6, the fixing plate 1 5 and the fixing plate 2 6 are fixedly connected to the outer wall by bolts, and fixing mechanisms are provided on both sides of the sleeve 1.

[0031] When installing the sleeve, first insert the sleeve 1 into one side of the sleeve 2, and then fix it to the side of the fixing plate 1 5 through the fixing plate 2, so that the sleeve 2 is fixed to the outside of the sleeve 1. After the fixation is completed, the plug-in block 3 and the plug-in groove 4 are continuously plugged together to complete the installation of the thermal insulation sleeve. The fixing mechanism can reduce the inconvenience of the staff in fixing the sleeve 1 and the sleeve 2, thereby improving work efficiency.

[0032] Reference Figures 1 to 3 The fixing mechanism includes a fixing seat 7 fixedly connected to the outside of the sleeve 1, a moving hole 13 is opened on the outside of the fixing seat 7, a moving column 14 is slidably connected to the inside of the moving hole 13, and a resistance block 15 is fixedly connected to the end of the moving column 14 away from the fixing seat 7. Connecting plates 17 are fixedly connected on both sides of the sleeve 2, a moving hole 2 19 is opened inside the connecting plate 17, the resistance block 15 is slidably connected to the moving hole 2 19, and a resistance block 2 18 is fixedly connected to the side of the connecting plate 17 close to the fixing seat 7. The resistance block 15 is in conflict with the resistance block 2 18, and the contact surface between the resistance block 15 and the resistance block 2 18 is set as an inclined surface.

[0033] Among them, the side of the resisting block 15 close to the connecting plate 17 is fixedly connected to the metal plate 16, and the side of the metal plate 16 close to the connecting plate 17 is set to be a rough metal surface.

[0034] In addition, a fixing groove 8 is opened inside the fixing seat 7, and a movable plate 9 is slidably connected inside the fixing groove 8. A spring 10 is fixedly connected to one side of the movable plate 9, and the end of the spring 10 away from the movable plate 9 is fixedly connected to the inner wall of the fixing groove 8.

[0035] In addition, a sliding groove 11 is opened on the inner wall of the fixed groove 8, and a slider 12 is fixedly connected to the outer side of the movable plate 9. The shapes of the slider 12 and the sliding groove 11 are both set to be dovetail-shaped, and the slider 12 is slidably connected to the sliding groove 11.

[0036] When installing the sleeve 2, first insert the sleeve 2 into the outside of the sleeve 1. When the sleeve 2 is close to the sleeve 1, the sleeve 2 will drive the connecting plate 17 to the fixing seat 7. At this time, the interference block 18 will interfere with the interference block 15. The contact surface between the interference block 18 and the interference block 15 is set as an inclined surface. Under the action of the inclined surface, the interference block 15 moves inside the moving hole 19. When the interference block 15 is away from the interference block 18, the interference block 18 engages the connecting plate 17, so that the connecting plate 17 and the fixing seat 7 are fixed, thereby pre-fixing the sleeve 1 and the sleeve 2, reducing the tedious actions and coordination difficulty of the staff during the installation process, so that the staff do not need to hold the sleeve 2 by hand, and can perform subsequent fixing operations with both hands at the same time, reducing the inconvenience of the staff holding the sleeve for a long time, reducing the labor intensity, and reducing the difficulty of installation.

[0037] When the second abutment block 18 fixes the connecting plate 17, the metal plate 16 at the bottom of the second abutment block 18 abuts against the connecting plate 17, and the contact surface between the metal plate 16 and the connecting plate 17 is set to a rough surface, thereby increasing the friction between the second abutment block 18 and the connecting plate 17, making the connection between the connecting plate 17 and the fixing seat 7 more stable;

[0038] When the second contact block 18 contacts the first contact block 15, the force exerted on the first contact block 15 drives the movable column 14 to move, and the movement of the movable column 14 drives the movable plate 9 to move in the fixed groove 8. The movement of the movable plate 9 squeezes the spring 10, causing the spring 10 to contract and generate elastic potential energy. When the first contact block 15 moves away from the second contact block 18, the elastic potential energy of the spring 10 is released, causing the contact block to engage with the connecting plate 17.

[0039] When the movable plate 9 moves, the slider 12 and the slide groove 11 provide a guiding function for the movable plate 9, so that the movable plate 9 can maintain a correct movement trajectory when moving.

[0040] Reference Figure 1 、 Figure 2 and Figure 4 The two fixing seats 7 are fixedly connected to a bottom plate 20 on one side away from the sleeve 1, and a positioning column 21 is fixedly connected to the outer side of the bottom plate 20. Positioning holes 22 are opened inside the two connecting plates 17, and the positioning columns 21 and the positioning holes 22 are slidably arranged.

[0041] When the connecting plate 17 is close to the fixing seat 7, the connecting plate 17 drives the movable hole to move, so that the positioning column 21 on the fixing seat 7 is plugged into the positioning hole 22. The cooperation between the positioning column 21 and the positioning hole 22 can ensure that the position of the connecting plate 17 and the fixing seat 7 is accurate during connection, reduce deviations, and thus improve the accuracy of the entire installation. At the same time, additional support and fixing points are provided for the connecting plate 17 and the fixing seat 7, making the connection between the connecting plate 17 and the fixing seat 7 more stable.

[0042] Working principle: Insert sleeve 1 into one side of sleeve 2, and then fix it on one side of fixing plate 1 5 through fixing plate 2 6, so that sleeve 2 2 is fixed to the outside of sleeve 1. After the fixing is completed, the plug-in block 3 and the plug-in slot 4 are continuously plugged into each other to complete the installation of the thermal insulation sleeve. Insert sleeve 2 into the outside of sleeve 1. When sleeve 2 is close to sleeve 1, sleeve 2 will drive connecting plate 17 to approach fixing seat 7. At this time, interference block 2 18 will interfere with interference block 15. The contact surface between interference block 2 18 and interference block 15 is set as an inclined surface. Under the action of the inclined surface, the interference block 15 moves inside the moving hole 2 19. When the interference block 15 is away from the interference block 2 18, the interference block 2 18 engages the connecting plate 17 to fix the connecting plate 17 to the fixing seat 7, thereby pre-fixing sleeve 1 and sleeve 2 2, reducing the tedious actions and coordination difficulty of the staff during the installation process.

[0043] By setting the contact surface between the metal plate 16 and the connecting plate 17 to a rough surface, the friction between the interference block 2 18 and the connecting plate 17 is increased. The spring 10 enables the interference block 15 to automatically engage with the connecting plate 17. The positioning column 21 and the positioning hole 22 cooperate to ensure that the position of the connecting plate 17 and the fixing seat 7 is accurate during connection, reduce deviations, and thus improve the accuracy of the entire installation.
