[0029] Example:

[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, in the embodiments of this utility model are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0031] It should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0034] This utility model provides a technical solution: a mandrel assembly for a tube receiver, comprising a mandrel and a sleeve. The mandrel includes a first cylindrical body 1 and a second cylindrical body 2. The second cylindrical body 2 is rotatably sleeved on the first cylindrical body 1. The second cylindrical body 2 has a plurality of cavities 6 inside. The second cylindrical body 2 has a connecting end 3. A plurality of first through holes 4 are spaced apart on the connecting end 3. A plurality of second through holes 5 are opened on the circumferential surface of the second cylindrical body 2. The plurality of first through holes 4 are respectively connected to the plurality of second through holes 5 through the plurality of cavities 6. The sleeve 7 is fixedly sleeved on the second cylindrical body 2. A plurality of third through holes 8 are opened on the circumferential surface of the sleeve 7. The plurality of third through holes 8 are adapted to the plurality of second through holes 5.

[0035] Specifically, see Figures 1 to 8Compared to the disorganized distribution of through holes (connecting hose nozzles) in some existing mandrel assemblies, the first through holes 4 (used for connecting hose nozzles) on the connecting end 3 of this mandrel assembly are spaced out and neatly arranged. This mandrel assembly allows the hose reel to connect the nozzles of multiple hoses to the first through holes 4 when storing multiple hoses, resulting in a neater overall hose coiling and storage, thus achieving a better storage effect. Furthermore, this mandrel assembly can also perform material transfer. Through the multiple cavities 6 inside the second cylinder 2, combined with the multiple first through holes 4 on the connecting end 3 and the multiple second through holes 5 on its circumference, material can enter the cavity 6 through the first through holes 4, and then reach the second through holes 5 via the cavity 6, forming a multi-channel transfer path. This multi-channel design allows for the simultaneous supply or transfer of materials to components at different locations or with different needs, improving transfer efficiency. Furthermore, since multiple first through holes 4 are connected to multiple second through holes 5 through multiple cavities 6, this one-to-one connection method enables precise distribution and transmission of fluids or gases within the component. Each channel is relatively independent and does not interfere with each other, ensuring the accuracy and stability of transmission and preventing the mixing or mutual influence of substances between different channels, thus meeting the requirements of applications with high transmission accuracy. Simultaneously, the sleeve 7 provides protection for the second cylinder 2, allowing it to withstand more external forces without deformation. The third through hole 8 is the same size and position as the second through hole 5, enabling the exchange of substances (fluids or gases) with the external environment when the third through hole is connected to an external component, improving adaptability and stability. The relative rotation design of the first cylinder 1 and the second cylinder 2 further enhances the flexibility of this mandrel assembly, allowing it to be adjusted by rotation to meet the needs of different devices, such as position and angle, depending on the equipment requiring transmission.

[0036] As an optional implementation, in some embodiments, a plurality of first through holes 4 are spaced apart on the side of the connecting end 3, and a plurality of second through holes 5 are equally spaced along the length of the second cylinder 2 and are equally spaced around the central axis of the second cylinder 2. In practical use scenarios, various obstacles or irregular structures may be encountered, and opening the first through holes 4 on the side of the connecting end 3 can avoid various obstacles or irregular structures in front.

[0037] As an optional implementation, in some embodiments, a plurality of first through holes 4 are provided on the side of the connecting end 3 away from the second cylinder 2, and the plurality of first through holes 4 are arranged around the central axis of the second cylinder 2. A plurality of second through holes 5 are equally spaced along the length of the second cylinder 2 and are also equally spaced around the central axis of the second cylinder 2. The difference from the above embodiments is that the first through holes 4 are located on the side of the connecting end 3 away from the second cylinder 2, thus avoiding various obstacles or irregular structures on the side.

[0038] In some embodiments, multiple first through holes can be further formed on both the side of the connecting end and the side away from the second cylinder. With this structure, when using the first through hole on the side for transmission, the first through hole on the side away from the second cylinder needs to be blocked and closed; similarly, when using the first through hole on the side away from the second cylinder for transmission, the first through hole on that side needs to be blocked and closed. This allows for selection of a suitable side for connection based on the actual usage environment, greatly improving ease of use.

[0039] As an optional implementation, in some embodiments, the sleeve 7 has a plurality of first threaded holes 11 on the side away from the connecting end 3. In this way, when the mandrel assembly needs to be installed and fixed with other components, the first threaded holes 11 on the sleeve 7 can be threaded to connect, which is a simple and stable connection method.

[0040] In the above embodiments, a plurality of first threaded holes 11 are further arranged at equal intervals around the central axis of the sleeve 7. The equal-interval arrangement of the first threaded holes 11 allows the sleeve to evenly distribute the force to each of the first threaded holes 11 when subjected to external force, avoiding local stress concentration and thus improving the overall load-bearing capacity and stability of the sleeve 7.

[0041] As an optional implementation, in some embodiments, the connecting end 3 is provided with a plurality of second threaded holes 12, which are located on the edge of a side away from the second cylinder 2 and penetrate the connecting end 3. When the connecting end 3 needs to be installed and fixed with other components, the second threaded holes 12 on the connecting end 3 can be threaded together, providing a simple and stable connection.

[0042] As an optional implementation, in some embodiments, a bushing 9 is fitted onto the second cylinder 2 near the connecting end 3. The bushing 9 can withstand most of the friction and wear, increasing its service life, and can also absorb vibration and impact to a certain extent, improving operational stability.

[0043] As an optional implementation, in some embodiments, the end of the first cylinder 1 furthest from the connecting end 3 is provided with a plurality of limiting grooves 10 along its circumference. This effectively restricts the axial movement of the first cylinder 1 when the mandrel assembly needs to be installed in conjunction with other components (e.g., snap-fit ​​or protrusion), enhancing the stability of the overall structure. It also serves as a clear positioning mark, ensuring that other components (e.g., sealing rings, retaining rings, or fixing rings) are accurately aligned during assembly, preventing component displacement or functional failure due to assembly deviations.

[0044] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

They should not be construed as limiting the scope of protection of this utility model.
