[0002] Caulking glue is primarily used to fill and beautify gaps in tiles, stone, and other materials. Controlling its flow rate is crucial to achieving the desired effect. However, the fixed shape of the nozzle of a caulking glue hose also produces a fixed amount of glue, requiring adjustment in different situations. This requires replacing the nozzle, which is inconvenient. Utility Model Content

[0024] like Figure 1-4 As shown, a flow-adjustable seam-beautifying hose comprises a hose 1 and a glue outlet 2 connected to the hose 1;

[0025] The top of the hose 1 is provided with a glue outlet 101, and the outer periphery of the glue outlet 101 is provided with an annular fixed wall 3, the top of the inner wall of the annular fixed wall 3 is provided with a notch 301, and a limiting groove 302 is provided at the connection between the inner wall of the annular fixed wall 3 and the top of the hose; the notch 301 extends downward and is connected to the limiting groove 302;

[0026] The glue discharge nozzle 2 is composed of a chassis 201 and a glue discharge pipe 202, and the glue discharge pipe 202 is integrally connected to the chassis 201; the chassis 201 is circular, and the chassis 201 is provided with two symmetrical groups of right-angled fan-shaped cavities 2011; a limiting protrusion 2012 is provided on the side of the lower edge of the chassis 201, and the limiting protrusion 2012 is inserted into the notch 301 and is rotated and extruded to be connected with the limiting groove 302; a small-diameter glue discharge channel 2021 and a large-diameter glue discharge channel 2022 are provided in the glue discharge pipe 202, and one end of the small-diameter glue discharge channel 2021 and the large-diameter glue discharge channel 2022 are respectively led out from the top of the glue discharge nozzle, and the other end is respectively connected to the corresponding right-angled fan-shaped cavity 2011.

[0027] like Figure 2 As shown, the limiting protrusion 2012 is composed of an extrusion portion 20121 in the middle and guide portions 20122 on both sides. The guide portions 20122 on both sides are symmetrically arranged along the central axis of the extrusion portion 20121. The symmetrical limiting protrusion can enable the chassis to be fixed with the limiting groove when rotating left or right.

[0028] like Figure 1-3 As shown, the arc length of the limiting protrusion 2012 is smaller than the arc length of the notch 301, ensuring that the limiting protrusion can be inserted into the annular fixed wall. At the same time, the height of the limiting groove is slightly lower than the height of the extrusion part of the limiting protrusion, that is, when the limiting protrusion is rotated after insertion, the extrusion part can form extrusion with the limiting groove, further realizing the fixation of the entire chassis.

[0029] like Figure 4 As shown, when the guide part 20122 is rotated left to contact one end of the limiting groove 302, one group of right-angled fan-shaped cavities 2011 is connected to the glue outlet; when the guide part 20122 is rotated right to contact the other end of the limiting groove 302, the other group of right-angled fan-shaped cavities 2011 is connected to the glue outlet. By rotating the chassis, two glue outlet channel outputs with different diameters can be realized, which can meet the needs of different scenarios.

[0030] like Figure 2 As shown, a rubber gasket (not shown in the figure) is provided at the bottom of the chassis between the two groups of right-angled fan-shaped cavities 2011. After the rubber gasket is squeezed, it can further increase the sealing between the chassis and the top of the hose to ensure that the caulking glue will not leak during use.

[0031] like Figure 3 As shown, the annular fixed wall 3 is divided into four quadrants with its origin as the center, and the glue outlet 101 is located in one of the quadrants, ensuring that the glue outlet can be connected to the right-angled fan-shaped cavity and further form a loop with the glue outlet pipe.

[0032] The working principle of the utility model is as follows: when in use, the output channels of different apertures are selected according to actual needs, the chassis is directly inserted into the annular fixed wall, and the output channels of different apertures are selected by rotating it left or right. The utility model is easy to disassemble and install, and has a wide range of applications.

[0033] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content sought to be protected by the present invention is fully set forth in the claims.
