Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figures 1-4 As shown, this utility model is a pilot-operated hydraulic lock multi-way directional valve assembly, comprising:

[0028] A multi-way reversing assembly, comprising a valve body 11 and a connection port 13; the connection port 13 is fixed to both sides of one end of the valve body 11.

[0029] The multi-way reversing assembly also includes a connecting end 12, an upper connecting end 14, and a movable rod 15; the connecting end 12 is a set and is fixed to the front side of the valve body 11; the upper connecting end 14 is two sets and is fixed to the top of the valve body 11; the movable rod 15 is a set and is located on the back of the valve body 11.

[0030] Connection end 12, connection port 13 and upper connection end 14 are all used for connecting to other external components, and movable rod 15 is used to open the internal state of valve body 11.

[0031] The limiting assembly includes a fixed rod 21, a connecting rod 22, a moving rod 23, and a limiting frame 24. The fixed rod 21 is fixed to one edge of the front and back sides of the valve body 11, the connecting rod 22 is inserted into the opposite side of the outer end of the fixed rod 21, the moving rod 23 is slidably connected to the inside of the opposite end of the connecting rod 22, and the limiting frame 24 is fixed to the opposite end of the moving rod 23.

[0032] The fixed rod 21 is used to connect the connecting rod 22, the connecting rod 22 is used to connect the moving rod 23, the moving rod 23 is used to connect the limiting frame 24 and drive the limiting frame 24 to move, and the limiting frame 24 is used to limit the tube body of the connected tube after insertion.

[0033] The fixing rod 21 has an insertion groove 28 at the insertion point with the connecting rod 22, and the insertion groove 28 is threaded to the opposite end of the connecting rod 22.

[0034] A slot 25 is provided at the opposite end of the connecting rod 22, and a spring 26 is fixedly connected between the inner end of the slot 25 and the inner end of the moving rod 23.

[0035] The upper and lower ends of the limiting frame 24 are fixedly connected to magnetic blocks 27 on opposite sides, and the two are attracted to each other through magnetic blocks 27.

[0036] The insertion slot 28 is used for the insertion and rotation of the opposite ends of the connecting rod 22. One end of the connecting rod 22 is inserted into the insertion slot 28 and the connecting rod 22 is rotated so that the connecting rod 22 is connected to the fixed rod 21. The slot 25 is used for the connection of the spring 26 and the movement of the moving rod 23. The spring 26 is used for the connection between the inside of the slot 25 and the inner end of the moving rod 23. The magnetic block 27 is used for the magnetic connection between the limiting frames 24. When the tube body of the connecting tube is wide, the tube body squeezes the limiting frame 24, causing the spring 26 to contract. The spring 26 drives the moving rod 23 to move in the slot 25, so that the limiting frame 24 moves in opposite directions with the spring 26 through the moving rod 23. At the same time, the limiting frame 24 limits the tube body of the inner connecting tube through the spring 26.

[0037] Working principle: When the component is not in use, the external connecting tube is not inserted into the connection port 13. When the component is in use, the external connecting tube is inserted into the connection port 13. The tube body of the connecting tube presses against the limiting frame 24, causing the pressing force spring 26 to contract. The spring 26 drives the moving rod 23 to move within the slot 25, causing the limiting frame 24 to move away from the spring 26 via the moving rod 23. This allows the tube body of the connecting tube to enter the inner side of the limiting frame 24. At this time, the force of the pressing spring 26 disappears, and the spring 26 drives the limiting frame 24 to pop out via the moving rod 23. This causes the limiting frame 24 to be attracted by the magnetic block 27, causing the limiting frame 24 to limit the tube body of the inner connecting tube via the spring 26. When the connecting tube is detached from the connection port 13, the connecting tube hangs on the limiting frame 24, causing the limiting frame 24 to limit the detached connecting tube and prevent the detached connecting tube from being lost.

[0038] Please see Figures 1-5 As shown, this embodiment, based on the above embodiment, further includes:

[0039] Connection components;

[0040] The connecting components include a fixing plate 31, a snap-fit ​​groove 32, and a connecting groove 33; the fixing plate 31 is set in three groups and fixed to the inner and outer edges of one side of the limiting frame 24; the snap-fit ​​groove 32 is between the inner sides of the fixing plate 31; and the connecting groove 33 is opened in the middle of the outer vertical fixing plate 31.

[0041] The fixing plate 31 is used to form the snap-fit ​​groove 32, which is used for snap-fitting the limiting frame 24 on the other side, and the connecting groove 33 is used for inserting the moving rod 23.

[0042] A fixing block 34 is fixedly connected to the middle of the outer side of one side connecting rod 22, and an annular block 35 is fixedly connected to the outer end of the fixing block 34. The annular block 35 is engaged with the other side connecting rod 22.

[0043] The fixing block 34 is used to connect the ring block 35. The ring block 35 is made of PVC board and has toughness, so that the ring block 35 can be snapped into the connecting rod 22. The limiting frame 24 is not used. The connecting rod 22 is removed by hand by rotating it, and one side of the limiting frame 24 is inserted into the snap-fit ​​groove 32, so that the two limiting frames 24 are connected together. This allows the limiting frames 24 to be placed uniformly, avoiding the loss of the limiting frames 24.

[0044] Working principle: When the component is not in use, the connecting rod 22 is connected to the insertion slot 28, and the limiting frame 24 is in normal use. When the component is in use, the connecting rod 22 is removed by hand, so that the connecting rod 22 is separated from the insertion slot 28 by the thread. At this time, hold one limiting frame 24 in each hand and insert one limiting frame 24 into the snap-fit ​​slot 32, so that the connecting slot 33 is snapped into the moving rod 23 and the annular block 35 is snapped into the connecting rod 22, so that the two limiting frames 24 are connected together, which makes it easy to place the limiting frames 24 uniformly.

[0045] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
