[0001] This utility model relates to the field of precision rotary cutting hose technology, and in particular to an ultra-thin-walled lightweight precision rotary cutting hose. Background Technology

[0002] Ultra-thin-walled lightweight precision rotary-cut flexible hoses, commonly used in fluid transport and precision equipment connections, have wide applications in aerospace, medical devices, and precision instruments due to their thin walls and lightweight characteristics. These hoses need to achieve efficient and safe media transmission while ensuring structural strength, and often require multi-section connections or disassembly depending on actual usage requirements. Therefore, their connection methods and sealing performance are key factors affecting their performance.

[0003] In existing technologies, the connection of ultra-thin-walled lightweight precision rotary cutting hoses mainly adopts flange connections, threaded connections, or snap-fit ​​connections. Among them, flange connections require the use of multiple accessories such as bolts and nuts. Assembly and disassembly require the operation of each fastener individually, which is not only cumbersome and time-consuming, but also requires the assistance of special tools, greatly affecting the efficiency of assembly and maintenance. In terms of sealing performance, the unconnected hose ends in existing technologies are usually sealed only by simple plugs or gaskets. The sealing effect is greatly affected by factors such as material aging and installation accuracy, and media leakage is prone to occur. To address these issues, an ultra-thin-walled lightweight precision rotary cutting hose is provided. Utility Model Content

[0004] The purpose of this utility model is to provide an ultra-thin-walled, lightweight, precision rotary cutting hose to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultra-thin-walled, lightweight, precision rotary cutting hose, comprising: Rotary cutting hose body; A quick-connect mechanism for pipes is provided at both ends of each set of rotary cutting hose bodies. The quick-connect mechanism is used to quickly connect or disconnect two different sets of rotary cutting hose bodies end to end. An internal connection mechanism is provided inside the rotary cutting hose body. The internal connection mechanism is used to keep the two sets of rotary cutting hose bodies closed when they are not connected, and to maintain their internal communication state after the two sets of rotary cutting hose bodies are connected.

[0006] As a further improvement of this utility model: the quick-connect pipe mechanism includes an outer fixing ring, and two sets of hook-shaped locking blocks are symmetrically fixedly connected to the outer side of each set of outer fixing rings, and two sets of fan-shaped locking blocks are fixedly connected to the outer side of each set of outer fixing rings.

[0008] As a further improvement of this utility model, the outer fixing ring is fixedly connected to the outer sides of both ends of the rotary cutting hose body.

[0009] As a further improvement of this utility model, the groove at the front end of the hook-shaped locking block is adapted to the size of the fan-shaped locking block.

[0010] As a further improvement of this utility model, the inner annular support plate is fixedly connected to the inner sidewalls at both ends of each set of rotary cutting hose bodies.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The connection and disassembly of this utility model are efficient and convenient. Through the matching design of the hook-shaped locking block and the fan-shaped locking block in the quick connection mechanism, the two sets of rotary cutting hose bodies can be quickly locked and separated by simply rotating, without the need for complicated tools, which greatly improves the efficiency of assembly and maintenance.

[0012] 2. This utility model has reliable sealing performance. When not connected, the internal connecting mechanism pushes the circular sealing plug tightly against the inner annular support plate with the help of the support spring, effectively sealing the end of the rotary cutting hose body and preventing media leakage. After connection, the top blocks of the two sets of connecting columns squeeze each other, so that the rotary cutting hoses are automatically connected without manual operation. The two sets of different sealing rings further enhance the sealing effect of the connection part, ensuring that there is no risk of leakage during the flow of media. Attached Figure Description

The embodiments of this utility model will be described below based on its overall structure.

[0017] Reference Figures 1 to 4 In this embodiment of the present invention, an ultra-thin-walled lightweight precision rotary cutting hose includes: Rotary cutting hose body 1; The quick-connect mechanism 2 is provided at both ends of each set of rotary cutting hose bodies 1. The quick-connect mechanism 2 is used to quickly connect or disconnect two different sets of rotary cutting hose bodies 1. The internal connection mechanism 3 is located inside the rotary cutting hose body 1. The internal connection mechanism 3 is used to keep the two sets of rotary cutting hose bodies 1 closed when they are not connected, and to keep their internal connection state after the two sets of rotary cutting hose bodies 1 are connected.

[0018] The above scheme is adopted: the rotary cutting hose body 1 serves as the basic load-bearing structure, and the quick-connect mechanism 2, through its structure located at both ends of the rotary cutting hose body 1, enables the quick assembly and disassembly of the two sets of rotary cutting hose bodies 1; the internal connection mechanism 3 works in conjunction with the action of the quick-connect mechanism 2 to ensure that the two sets of rotary cutting hose bodies 1 are in a closed state when they are not connected, thus preventing leakage of internal media. When the connection is completed through the quick-connect mechanism 2, the internal connection mechanism 3 simultaneously switches to a connected state, so that a continuous channel is formed inside the two sets of rotary cutting hose bodies 1, ensuring that the media can flow smoothly.

[0019] The quick-connect mechanism 2 includes an outer fixing ring 21, which is fixedly connected to the outer sides of both ends of the rotary cutting hose body 1. Two sets of hook-shaped locking blocks 22 are symmetrically fixedly connected to the outer side of each set of outer fixing rings 21, and two sets of fan-shaped locking blocks 23 are fixedly connected to the outer side of each set of outer fixing rings 21. The groove size at the front end of the hook-shaped locking block 22 is adapted to the size of the fan-shaped locking block 23.

[0020] The above scheme is adopted: the outer fixing ring 21 provides fixed support for the hook-shaped locking block 22 and the fan-shaped locking block 23. When it is necessary to connect two sets of rotary cutting hose bodies 1, the hook-shaped locking block 22 on the outer fixing ring 21 at the end of one set of rotary cutting hose bodies 1 is aligned with the fan-shaped locking block 23 on the outer fixing ring 21 at the end of the other set of rotary cutting hose bodies 1. By rotating, the fan-shaped locking block 23 is inserted into the groove at the front end of the hook-shaped locking block 22. The matching of the two sizes is used to lock and complete the connection. When disassembling, the reverse operation is performed to make the fan-shaped locking block 23 disengage from the groove of the hook-shaped locking block 22, thereby realizing the separation of the two sets of rotary cutting hose bodies 1 and achieving the effect of quick connection and disassembly.

[0021] The internal connection mechanism 3 includes an inner annular support plate 31, which is fixedly connected to the inner sidewalls of both ends of each set of rotary cutting hose bodies 1. A circular sealing plug 32 is provided on the side of the inner annular support plate 31. A connecting column top block 33 is fixedly connected to the side of the circular sealing plug 32 through the inner side of the inner annular support plate 31. A support spring 34 is sleeved on the outer side of the connecting arm portion of the connecting column top block 33. A second sealing ring 36 is provided between every two sets of rotary cutting hose bodies 1, and a first sealing ring 35 is provided between every two sets of outer fixing rings 21.

[0022] The above scheme is adopted: the inner annular support plate 31 provides an installation base for the circular sealing plug 32, the connecting column top block 33, and the support spring 34. When the two sets of rotary cutting hose bodies 1 are not connected, the support spring 34 is in a naturally extended state, pushing the connecting column top block 33 so that the circular sealing plug 32 fits tightly against the side of the inner annular support plate 31, thereby sealing the end of the rotary cutting hose body 1 and preventing internal medium leakage. When the two sets of rotary cutting hose bodies 1 are connected through the quick pipe connection mechanism 2, the connecting column top blocks 33 at the ends of the two sets of rotary cutting hose bodies 1 abut against each other and squeeze the support spring 34, causing the support spring 34 to contract and drive the circular sealing plug 32 to separate from the inner annular support plate 31. At this time, the interiors of the two sets of rotary cutting hose bodies 1 are connected through the end openings. At the same time, the first sealing ring 35 is squeezed between the two sets of outer fixing rings 21, and the second sealing ring 36 is squeezed between the two sets of rotary cutting hose bodies 1, respectively enhancing the sealing performance of the exterior and the connection, and preventing medium leakage at the connection.

[0023] The working principle of this utility model is as follows: When no connection operation is performed, the rotary cutting hose body 1 serves as the basic load-bearing structure, and the internal connecting mechanism 3 on both ends of the hose is in a closed state. The inner annular support plate 31 provides an installation base for the circular sealing plug 32, the connecting column top block 33, and the support spring 34. The support spring 34 extends naturally, pushing the connecting column top block 33 to make the circular sealing plug 32 tightly fit against the side of the inner annular support plate 31, thereby sealing the end of the rotary cutting hose body 1 and preventing internal medium leakage. At this time, the outer fixing ring 21 of the quick connection mechanism 2 and its corresponding hook-shaped locking block 22 and fan-shaped locking block 23 are in a ready-to-connect state.

[0024] When it is necessary to connect two sets of rotary cutting hose bodies 1, the quick connection mechanism 2 of the operating tube is assembled: the hook-shaped locking block 22 on the outer fixing ring 21 at the end of one set of rotary cutting hose bodies 1 is aligned with the fan-shaped locking block 23 of the other set, and the fan-shaped locking block 23 is inserted into the groove at the front end of the hook-shaped locking block 22 by rotation. Locking is achieved by using size adaptation, and the quick connection of the two sets of rotary cutting hose bodies 1 is completed.

[0025] After connection, the internal connecting mechanism 3 of the pipe synchronously switches to the connected state: the connecting column top blocks 33 at the ends of the two sets of rotary cutting hose bodies 1 abut against each other and squeeze the support spring 34, causing it to contract, which drives the circular sealing plug 32 to separate from the inner annular support plate 31. The two sets of rotary cutting hose bodies 1 form a continuous channel through the end opening to ensure smooth flow of the medium. At the same time, the first sealing ring 35 is squeezed between the two sets of outer fixing rings 21, and the second sealing ring 36 is squeezed between the two sets of rotary cutting hose bodies 1, which respectively enhances the sealing performance of the outside and the connection, and avoids medium leakage.

[0026] If disassembly is required, rotate the two sets of rotary cutting hose bodies 1 in the opposite direction to disengage the fan-shaped locking block 23 from the groove of the hook-shaped locking block 22, thereby separating the two sets of rotary cutting hose bodies 1. At this time, the support spring 34 of the internal connecting mechanism 3 returns to its natural extended state, pushing the connecting column top block 33 to re-close the end of each rotary cutting hose body 1 with the circular sealing plug 32, ensuring the sealing performance in the single-tube state.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
