[0016] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0017] Please refer to Figures 1 to 5 As shown, a flow regulating switch of the present invention comprises: The fixing tube 1 has an assembly hole 11 inside and a through hole 12 penetrating to the assembly hole 11 on the side wall; The regulating tube 2 has a flow guide hole 21 inside, and the side wall has two or more regulating holes 22 penetrating to the flow guide hole 21 along the circumferential direction. The apertures of the two or more regulating holes 22 gradually increase along the circumferential direction. The regulating tube 2 is rotatably arranged in the assembly hole 11. The through hole 12 is located on the circumference where the two or more adjustment holes 22 are located. The through hole 12 is connected to the first body, and the guide hole 21 is connected to the second body.

[0018] From the above description, it can be seen that the beneficial effects of the present invention are: a flow regulating switch, the regulating tube 2 and the fixed tube 1 are arranged in an inner and outer nested manner, when the regulating tube 2 is rotated to align an adjusting hole 22 with the through hole 12, the guide hole 21, the regulating hole 22 and the through hole 12 are connected to form a passage, and the two ends of the passage are respectively connected to the first body and the second body, and the passage flux size can be changed by rotating the regulating tube 2 to make the regulating holes 22 with different apertures connect with the through hole 12. When the regulating tube 2 rotates in the same direction, the oil path flux size is gradually increased or decreased, thereby accurately and quickly adjusting the flow size.

[0019] In an optional embodiment, a connecting seat 5 is further included, a mounting hole 51 is provided inside the connecting seat 5, a first connecting hole 52 and a second connecting hole 53 are provided on the side wall of the connecting seat 5 which pass through the mounting hole 51, the fixing pipe 1 is fixedly arranged in the mounting hole 51, the through hole 12 is connected to the first connecting hole 52, the guide hole 21 is connected to the second connecting hole 53, the first connecting hole 52 is connected to the first body, and the second connecting hole 53 is connected to the second body.

[0020] From the above description, it can be seen that the connecting seat 5 plays the role of installing parts and the first body and the second body.

[0022] From the above description, it can be seen that the annular guide groove 13 and the inner wall of the mounting hole 51 form an annular liquid storage cavity, and the liquid entering and exiting from the through hole 12 needs to pass through the annular liquid storage cavity and then enter and exit from the first connecting hole 52. Due to the provision of the annular liquid storage cavity, the annular liquid storage cavity is in a state of being filled with medium when the passage is connected, so that the flow of the medium is continuous and smooth regardless of switching between the larger-diameter adjustment hole 22 and the smaller-diameter adjustment hole 22. For example, when the shock absorber flow is switched, it can avoid setbacks and improve the use experience.

[0023] In an optional embodiment, the inner wall of the mounting hole 51 is provided with an internal thread, and the outer wall of the fixing pipe 1 is provided with an external thread connected to the internal thread.

[0029] In an optional embodiment, the knob 6 is provided with a spring bead 61 , and the fixing tube 1 is provided with more than two gear holes 14 engaged with the spring bead 61 .

[0030] It can be known from the above description that when the spring bead 61 is engaged with the different gear holes 14 , the corresponding through hole 12 is connected with the guide holes 21 with different apertures, thereby changing the flow rate of the passage.

[0031] In an optional embodiment, the number of the adjustment holes 22 is the same as the number of the gear holes 14 , and the central angle corresponding to two adjacent adjustment holes 22 is equal to the central angle corresponding to two adjacent gear holes 14 .

[0032] From the above description, it can be seen that the above design is adopted to ensure the accuracy of flow regulation, and each gear accurately corresponds to a flow size.

[0033] In an optional embodiment, the knob 6 is provided with an arc-shaped groove 62 , the fixing tube 1 is provided with a positioning hole 15 , and a ball 16 embedded in the arc-shaped groove 62 is provided in the positioning hole 15 .
