[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0027] like Figure 1-Figure 7 As shown, the embodiment of the present application proposes a tightening type hydraulic multi-way valve, comprising:

[0028] A valve body 1, a main flow channel 2 is provided at the bottom of the valve body 1, the valve body 1 is used to be connected to a hydraulic pump, the main flow channel 2 is communicated with the hydraulic pump, a mounting groove 3 is provided at the top of the valve body 1 and is communicated with the main flow channel 2, and a plurality of branch flow channels 4 are provided in an annular array on the outer surface of the valve body 1 and are communicated with the mounting groove 3, and the branch flow channels 4 are used to be communicated with different oil circuits;

[0029] The switching member 5 includes a rotating column 501 rotatably arranged in the mounting groove 3, and a connecting channel 502 is provided on the rotating column 501. The connecting channel 502 has a vertical channel 5021 and a horizontal channel 5022 that are connected to each other. The vertical channel 5021 is connected to the main channel 2, and the horizontal channel 5022 corresponds to the branch channel 4. The rotating column 501 is rotated to make the horizontal channel 5022 of the connecting channel 502 rotate horizontally. The horizontal channel 5022 can be separately connected to several branch channels 4, so that the main channel 2, the connecting channel 502 and the branch channel 4 can be connected to form an oil channel. After twisting the rotating column 501, multiple oil channels can be switched. Channel, an opening and closing member 503 is arranged on the rotating column 501, and the opening and closing member 503 is used for blocking or unblocking the horizontal channel 5022. By arranging the opening and closing member 503 on the rotating column 501, it can not only open or block the oil channel, but also, no matter how the rotating column 501 rotates to switch any oil channel, the opening and closing member 503 can open or connect the connected oil channels. The overall structure of the device only needs to twist the rotating column 501 to rotate, and cooperate with the opening and closing of the opening and closing member 503 to switch any oil channel, so as to meet the oil supply channels of different operation requirements, thereby improving practicality.

[0030] like Figure 2 and Figure 4 As shown, in some embodiments, the opening and closing member 503 includes an opening and closing groove 5031 opened in the rotating column 501 and connected to the transverse channel 5022, an opening and closing rod 5032 is movably inserted in the opening and closing groove 5031, and an adjusting member 5033 for adjusting the lifting of the opening and closing rod 5032 is provided on the rotating column 501. Preferably, the opening and closing groove 5031 and the transverse channel 5022 are in a vertical state. When the bottom end of the opening and closing rod 5032 is aligned with the inner bottom wall of the opening and closing groove 5031, the opening and closing rod 5032 is moved downward. When overlapped, the opening and closing rod 5032 blocks the connecting opening between the opening and closing groove 5031 and the transverse channel 5022, thereby blocking the transverse channel 5022 and the connecting channel 502. When the sliding opening and closing rod 5032 moves upward so that its bottom end is higher than the connecting opening of the transverse channel 5022, the connecting channel 502 can be opened. The opening and closing rod 5032 can be raised and lowered by adjusting the adjustment part 5033 to realize the opening and closing of the connecting channel 502.

[0031] like Figure 1-Figure 4 As shown, in some embodiments, the adjustment member 5033 includes a resistance spring 50331, which is arranged between the bottom of the opening and closing rod 5032 and the opening and closing groove 5031. The outer surface of the opening and closing rod 5032 is provided with an annular groove 50332, and the top of the opening and closing rod 5032 is connected to the adjustment rod 50333. The rotating column 501 is hinged with a lever 50334 that overlaps with the adjustment rod 50333. Figure 4As shown in the figure, under the elastic force of the resisting spring 50331, the annular groove 50332 and the connecting opening of the transverse channel 5022 are in a misaligned state. At this time, the connecting channel 502 is in a closed state. When it needs to be opened, the adjusting rod 50333 is pressed downward, so that the opening and closing rod 5032 slides downward, and the annular groove 50332 and the connecting opening of the transverse channel 5022 and the opening and closing groove 5031 are aligned. At this time, the connecting channel 502 is in an open state. When it needs to be closed again, it only needs to loosen the adjusting rod 50333. The section rod 50333 is automatically closed under the elastic force of the resistance spring 50331. By hingedly connecting the lever 50334 to the rotating column 501 and holding the lever 50334 and rotating it horizontally, the rotating column 501 can be driven to rotate and switch the oil circuit. At the same time, the lever 50334 is pressed to rotate around the hinge point, and it overlaps with the end of the adjusting rod 50333, and the adjusting rod 50333 can be pressed to slide. The overall structure can realize oil circuit switching and oil circuit opening and closing with one hand, thereby improving convenience.

[0032] like Figure 1 and Figure 3 As shown, in some embodiments, the lever 50334 is constructed as a V-shaped rod, and its V-shaped tip is hinged to the rotating column 501. A through slot 6 is opened on the lever 50334, and an axle rod 7 is constructed at the end of the adjusting rod 50333. The end of the axle rod 7 slides through the through slot 6. By constructing the lever 50334 into a V shape and through the sliding fit of the through slot 6 and the axle rod 7, the lever 50334 is slidably connected with the adjusting rod 50333, which makes it more convenient and quick to switch the oil circuit when adjusting the rotating column 501 or to open and close the oil circuit.

[0033] like Figure 1 and Figure 4 As shown, in some embodiments, a positioning member 8 is provided on the rotating column 501, which is used to accurately align the transverse channel 5022 with the branch channel 4. Since the transverse channel 5022 is located in the mounting groove 3 and is in a hidden design, the positioning member 8 is provided, which makes switching the oil circuit more accurate and convenient.

[0034] like Figure 5As shown, in some embodiments, the positioning member 8 includes a slot 801 provided on the outer wall of the rotating column 501, a plug rod 802 is movably inserted in the slot 801, a limit spring 803 is installed between the plug rod 802 and the slot 801, an annular groove 804 is provided on the inner wall of the mounting groove 3, a plurality of annularly distributed plug holes 805 are provided on the inner wall of the annular groove 804, the plug rod 802 is inserted and matched with the plug hole 805, preferably, the outer edge of the socket of the plug hole 805 is in an arc-shaped structure, and the end of the plug rod 802 located outside the slot 801 is also in an arc-shaped structure, through the arc-shaped structure of the plug rod 802 and the plug hole 805, only a certain force needs to be applied to make the plug rod 802 detach from the plug hole 805, so that the rotating column 501 is not affected. Normal rotation, at the same time, when the insertion rod 802 is disengaged from the socket 805 and the rotating column 501 rotates, the insertion rod 802 is resisted by the elastic force of the limiting spring 803, and its arc-shaped end resists the inner wall of the annular groove 804. When the rotating column 501 rotates, so that the insertion rod 802 is aligned with the corresponding socket 805, the insertion rod 802 is automatically inserted into the socket 805 under the elastic force of the limiting spring 803. When the insertion rod 802 is inserted into the socket 805, there is a certain sense of jamming. Preferably, several sockets 805 correspond to several diversion channels 4 one by one, and the slot 801 corresponds to the transverse channel 5022. By twisting the rotating column 501 to rotate, the alignment of the diversion channel 4 and the transverse channel 5022 can be accurately judged by the jamming.

[0035] like Figure 7 As shown, in some embodiments, a first annular embedding groove 9 is opened on the inner wall of the mounting groove 3, and a first sealing ring 10 is fixedly provided on the rotating column 501. The first sealing ring 10 is rotatably inserted in the first annular embedding groove 9. By setting the first sealing ring 10, the sealing between the rotating column 501 and the mounting groove 3 can be ensured without affecting the rotation of the rotating column 501, thereby improving practicality.

[0036] like Figure 6 As shown, in some embodiments, the inner wall of the mounting groove 3 is provided with a second annular embedding groove 11 connected with a plurality of branch channels 4, a second sealing ring 12 is arranged in the second annular embedding groove 11, a plurality of through holes 13 are provided on the second sealing ring 12, and the plurality of through holes 13 correspond to the plurality of branch channels 4 one by one, respectively, and the outer surface of the rotating column 501 is provided with a nozzle 14 connected with the transverse channel 5022, the nozzle 14 is in contact with and overlaps the second sealing ring 12, when the rotating column 501 rotates, the nozzle 14 is in contact with the inner side wall of the second sealing ring 12, because the through hole 13 is correspondingly connected with the branch channel 4, therefore, when the rotating column 501 rotates, and the nozzle 14 is aligned with the through hole 13 and the branch channel 4, not only can an oil pipeline be formed, but also the sealing of the connection between the transverse channel 5022 and the branch channel 4 is ensured.
