[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-4 This invention discloses a pipe bladder disassembly and assembly device with a protective structure, including an operating rod 1, which is hollow. A lower protective shell 2 is provided at one end of the operating rod 1, and an upper protective shell 3 is provided above the lower protective shell 2. Both the upper protective shell 3 and the lower protective shell 2 are arc-shaped. A rubber bladder 4 is provided between the upper protective shell 3 and the lower protective shell 2. An air pipe 5 is connected to one side of the rubber bladder 4. The end of the air pipe 5 away from the rubber bladder 4 passes through the operating rod 1 and extends to the outside of the operating rod 1.

[0021] In this embodiment, the upper protective shell 3 and the lower protective shell 2 are used to protect the rubber bladder 4, preventing it from breaking when it encounters impurities, welding slag, or sharp objects on the pipe wall during the process of being pushed into the pipe. Specifically, when installing the rubber bladder 4, the user can place the rubber bladder 4 between the upper protective shell 3 and the lower protective shell 2, then straighten the air tube 5, and pass the end of the air tube 5 away from the rubber bladder 4 through the operating rod 1 and lead it out from the other end of the operating rod 1.

[0022] One end of the operating lever 1 is equipped with a clamping assembly for clamping the air tube 5. The clamping assembly includes a positioning ring 9 fixedly installed on one end of the operating lever 1, and a positioning clamp 10 for clamping one end of the air tube 5 is installed on the surface of the positioning ring 9.

[0023] With the clamping assembly in place, after one end of the air tube 5 is led out from one end of the operating rod 1, the user can hold the operating rod 1 and push the protected rubber bulb 4 into the inside of the pipe. Then, air is injected into the rubber bulb 4 through the air tube 5, causing it to expand and seal the pipe. After the rubber bulb 4 expands, the user can bend one end of the air tube 5 and then clamp the bend of the air tube 5 with the positioning clamp 10 to prevent the rubber bulb 4 from leaking air. With the positioning ring 9 in place, the positioning clamp 10 can be installed together with the operating rod 1.

[0024] A first movable connecting assembly and a second movable connecting assembly are respectively provided between the upper protective shell 3 and the lower protective shell 2 and the operating lever 1. The upper protective shell 3 and the lower protective shell 2 are movably installed to one end of the operating lever 1 through the first movable connecting assembly and the second movable connecting assembly, respectively. The first movable connecting assembly includes a first connecting member 11 hinged to the bottom of the upper protective shell 3. A hinge member 12 is fixedly connected to the end of the first connecting member 11 away from the upper protective shell 3. A second connecting member 13 is movably installed to the end of the first connecting member 11 away from the upper protective shell 3 through the hinge member 12. The second movable connecting assembly includes a hinge... A third connector 14 is attached to the top of the lower protective shell 2. A fourth connector 15 is fixedly connected to the end of the third connector 14 away from the lower protective shell 2. The second connector 13 and the fourth connector 15 are locked and fixed to one end of the operating rod 1 by a locking assembly. The locking assembly includes a locking rod 16 located below the fourth connector 15. The top end of the locking rod 16 passes through the fourth connector 15, the operating rod 1, and the second connector 13 in sequence and extends to the top of the second connector 13. A locking nut 17 is threaded to the top end of the locking rod 16. The bottom of the locking nut 17 is in contact with the top of the second connector 13.

[0025] By using the first and second movable connecting components together, the upper protective shell 3 and the lower protective shell 2 can be movably installed on one end of the operating rod 1, so that the user can push the rubber bladder 4 into the inner cavity of the pipe in a direction perpendicular to the pipe. When the rubber bladder 4 is pushed into the inner cavity of the pipe, the first connecting member 11 and the second connecting member 13 will change angles as they come into contact with the inner wall of the pipe. The connection between the first connecting member 11 and the upper protective shell 3 and the connection between the third connecting member 14 and the lower protective shell 2 are also movable hinges. The angle change can satisfy the user to push the rubber bladder 4 into the inner cavity of the pipe in a direction perpendicular to the pipe.

[0026] By setting the locking assembly, the first movable connecting assembly and the second movable assembly can be installed on one end of the operating lever 1, thereby installing the upper protective shell 3 and the lower protective shell 2 together with the operating lever 1 through the first movable connecting assembly and the second movable connecting assembly. During installation, the user can attach the second connecting piece 13 and the fourth connecting piece 15 to the upper and lower sides of one end of the operating lever 1, respectively, and then pass the top end of the locking rod 16 through the fourth connecting piece 15, the operating lever 1, and the second connecting piece 13 in sequence from bottom to top, and tighten the locking nut 17 at the top end of the locking rod 16 to install the first movable connecting assembly and the second movable connecting assembly on one end of the operating lever 1.

[0027] It is worth noting that the surface of the operating lever 1 is provided with a through hole 18 that is compatible with the locking lever 16. The surface of the locking lever 16 is slidably connected to the inner cavity of the through hole 18. By setting the through hole 18, one end of the locking lever 16 can easily pass through the operating lever 1. When the locking lever 16 is inserted, one end of the locking lever 16 will pass through the through hole 18 and move to the outside of the operating lever 1.

[0028] The inner cavity of the lower protective shell 2 is equipped with an elastic limiting component for limiting the upper protective shell 3. The elastic limiting component includes a tension spring 6 located in the inner cavity of the lower protective shell 2. Both ends of the tension spring 6 are provided with positioning components. Both ends of the tension spring 6 are fixedly installed in the inner cavity of the lower protective shell 2 through the positioning components. The positioning components include fixing rings 7 fixedly installed on both sides of the inner cavity of the lower protective shell 2. Both ends of the tension spring 6 are fixedly installed with connecting rings 8. The connecting rings 8 and the fixing rings 7 are sleeved together.

[0029] By using the elastic limiting component, the upper protective shell 3 and the lower protective shell 2 can be elastically connected together to prevent the upper protective shell 3 from flipping over and failing to protect the rubber bladder 4 when the device is moved. After placing the rubber bladder 4 on top of the lower protective shell 2, the user can pass one end of the upper protective shell 3 through the bottom of the tension spring 6, so that the bottom of the upper protective shell 3 fits against the top of the rubber bladder 4. As air is continuously injected into the rubber bladder 4, its expansion will push the upper protective shell 3 upward. The upper protective shell 3 will move under force and apply force to the surface of the tension spring 6, causing it to stretch and deform. The reaction force generated by the stretching of the tension spring 6 will then act on the surface of the upper protective shell 3, pressing it tightly against the surface of the rubber bladder 4. By using the positioning component, the tension spring 6 can be installed and fixed in the inner cavity of the lower protective shell 2.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
