Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0019] Specific implementation examples are given below.

[0020] Please see Figures 1-4 This utility model provides a road pothole filling device, including a base 1, an inlet 2, an outlet 3, a mixing assembly 4, an outlet pipe 5, a fixing structure 6, and an extension pipe 7. The mixing assembly 4 is mounted on the base 1 and includes a mixing drum and a mixing rod. The mixing drum is mounted on the top of the base 1, and the mixing rod is mounted inside the mixing drum. The mixing assembly 1 is connected to a power generation device. The inlet 2 is mounted on the top of the mixing drum, the outlet 3 is mounted at the front end of the mixing drum, the outlet pipe 5 is mounted at the front end of the outlet, and the extension pipe 7 is mounted at the front end of the outlet pipe 5. The fixing structure 6 is mounted between the outlet pipe 5 and the extension pipe 7 and connects the outlet pipe 5 and the extension pipe 7, providing auxiliary fixing and sealing between the outlet pipe 5 and the extension pipe 7.

[0021] The fixed structure 6 includes a sealing component 601 and an auxiliary component 602. The sealing component 601 is disposed outside the discharge pipe 5, and the auxiliary component 602 is disposed at the rear end of the sealing component 601. The sealing component 601 includes a cylinder 6011, a rubber airbag 6012, and a pressure plate 6013. The cylinder 6011 is fixedly sleeved on the outer surface of the discharge pipe 5. The rubber airbag 6012 and the pressure plate 6013 are disposed inside the cylinder 6011. The pressure plate 6013 divides the interior of the cylinder 6011 into a squeezing chamber and a movable chamber. The pressure plate 6013 slides inside the cylinder. The side plate of the pressure plate 6013 is flush with the inner wall of the cylinder 6011 and the outer wall of the discharge pipe 5. The rubber airbag 6012 is installed in the extrusion chamber, and the auxiliary component 602 is installed in the movable chamber. The deformation degree of the rubber airbag 6012 is adjustable. The extension tube 7 is installed between the rubber airbag 6012 and the discharge pipe 5. In order to better restrict the rubber airbag 6012, a ring is fixedly installed at the front end of the cylinder 6011 to restrict the front end of the rubber airbag 6012. The rear end of the extension tube 7 is installed between the cylinder 6011 and the ring. The inner diameter of the ring at the end near the rubber airbag 6012 is smaller than the inner diameter at the other end. This arrangement makes it easier to insert the extension tube 7 into the inner wall of the cylinder 6011 when installing the extension tube 7.

[0022] Auxiliary component 602 includes auxiliary plate 6021 and connecting rod 6022. Auxiliary plate 6021 is located at the rear end of cylinder 6011. Auxiliary plate 6021 includes main plate and ear plate. Main plate is sleeved on the outside of discharge pipe 5, and ear plate is attached to the outer wall of discharge pipe 5. Connecting rod 6022 passes through the rear plate of cylinder 6011 and is slidably connected to the rear plate of cylinder 6011. One end of connecting rod 6022 is vertically fixed to the main plate of auxiliary plate 6021, and the other end of connecting rod 6022 is connected to pressure plate 6013. Pushing auxiliary plate 6021, auxiliary plate 6021 drives connecting rod 6022, which in turn pushes pressure plate 6013 to slide on the inner wall of cylinder 6011. Pressure plate 6013 compresses rubber airbag 6012, causing rubber airbag 6012 to explode. The rubber airbag 6012 deforms until its outer surface is in close contact with the outer surface and connection of the discharge pipe 5 and the extension pipe 7. The rubber airbag 6012 then seals the connection between the discharge pipe 5 and the extension pipe 7. The friction between the rubber airbag 6012 and the discharge pipe 5 and the extension pipe 7 also helps to fix the discharge pipe 5 and the extension pipe 7. An air hole 6023 is provided on the movable chamber. When the pressure plate 6013 gradually squeezes the rubber airbag 6012, and the rubber airbag 6012 comes into contact with the cylinder 6011 and the discharge pipe 5, the movable chamber forms a sealed space. At this time, under atmospheric pressure, it is difficult to push the pressure plate 6013. The air hole 6023 is there to connect the movable chamber to the outside world, facilitating the pushing of the pressure plate 6013.

[0023] The auxiliary plate 6021 is provided with a bolt group 603, which includes a screw hole block and a bolt. The bolt passes through the screw hole block and the auxiliary plate 6021 and abuts against the discharge pipe 5. The bolt can fix the auxiliary plate 6021 and the discharge pipe 5, thereby fixing the pressure plate 6013. This helps to prevent the pressure plate 6013 from moving and causing the rubber airbag 6012 to reset.

[0024] To more quickly release the restriction on the rubber airbag 6012, a return spring is fitted onto the connecting rod 6022. One end of the return spring is fixedly connected to the pressure plate 6013, and the other end is fixedly connected to the rear plate of the cylinder 6011. By setting the return spring, when the auxiliary plate 6021 is pushed to drive the pressure plate 6013 to squeeze the rubber airbag 6012, the pressure plate 6013 will stretch the return spring, causing the return spring to deform. Then, the force applied to the auxiliary plate 6021 is removed, and the return spring will reset, driving the pressure plate 6013 and the rubber airbag 6012 to reset. This facilitates the quick release of the restriction of the rubber airbag 6012 on the extension tube 7, making it easier to disassemble the extension tube 7.

[0025] A rubber strip is provided between the discharge pipe 5 and the auxiliary plate 6021. By providing the rubber strip, it can replace the outer surface of the discharge pipe 5 to abut against one end of the bolt, which helps to prevent the bolt from loosening. A blocking component is provided at the rear end of the extension pipe 7. The blocking component is made of silicone, is ring-shaped, and is sleeved on the cylinder 6011. The blocking component abuts against the front end of the rubber airbag 6012. By providing the blocking component, when the rubber airbag 6012 deforms, it can replace one end of the extension pipe 7 to abut against the outer surface of the rubber airbag 6012, thereby providing a certain degree of protection for the rubber airbag 6012 and preventing the rubber airbag 6012 from being damaged due to excessive compression between one end of the extension pipe 7 and the rubber airbag 6012.

[0026] Among them, the feed inlet 2, the mixing drum, the discharge outlet 3, the discharge pipe 5, and the extension pipe 7 are all connected.

[0027] The working principle of this utility model is as follows: One end of the extension tube 7 is passed through the ring and inserted into the inside of the cylinder 6011. The extension tube 7 is rotated to make the extension tube 7 and the discharge tube 5 threaded together until one end of the extension tube 7 abuts against one side of the barrier. The auxiliary plate 6021 is pushed, and the auxiliary plate 6021 will drive the pressure plate 6013 connected to the connecting rod 6022 to slide on the inner wall of the cylinder 6011. The pressure plate 6013 will compress the rubber airbag 6012, causing the rubber airbag 6012 to deform until the outer surface of the rubber airbag 6012 is in contact with the outer surface of the discharge tube 5 and the extension tube 7 at the connection point. All parts are tightly connected. Then, rotate the bolt so that one end of the bolt abuts against the rubber strip on the outer surface of the discharge pipe 5. The bolt can then fix the auxiliary plate 6021 and the discharge pipe 5, and thus fix the pressure plate 6013. This helps to prevent the pressure plate 6013 from shifting and causing the rubber airbag 6012 to reset. Rotate the bolt in the opposite direction so that the bolt moves away from the rubber strip. The reset spring will reset and drive the pressure plate 6013 and the rubber airbag 6012 to reset. This makes it easier to quickly release the rubber airbag 6012 from limiting the extension pipe 7 and facilitate the disassembly of the extension pipe 7.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
