Description

Technical Field

[0001] This utility model belongs to the field of braided hose technology, and in particular relates to a double-layer ultra-flexible high-density military standard medium and high pressure braided hose. Background Technology

[0002] In the field of industrial fluid transfer, braided hoses are widely used due to their flexibility and pressure resistance. Traditional braided hoses are usually fixed to the two ends by hexagonal nuts and connectors, and the tightness needs to be adjusted by tightening the nuts at both ends during installation.

[0003] However, in practice, operators need to use tools to tighten the nuts and repeatedly adjust their positions, which can easily lead to uneven force application, resulting in low installation efficiency and inconvenience in operation.

[0004] To address the aforementioned issues, this utility model document proposes a double-layer ultra-flexible high-density military standard medium- and high-pressure braided hose. Utility Model Content

[0005] The purpose of this utility model is to provide a double-layer ultra-flexible high-density military standard medium and high pressure braided hose with a simple overall structure, no need for complicated auxiliary tools, suitable for single-person operation, reducing installation difficulty, and solving existing technical problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A double-layer ultra-flexible high-density military-standard medium- and high-pressure braided hose, used for convenient installation and disassembly of braided hoses, comprising: The braided hose body includes an inner layer and an outer layer. The inner layer is a hose made of polytetrafluoroethylene (PTFE), and the outer layer is a stainless steel wire braided layer made of three-dimensionally woven stainless steel wire. Both ends of the braided hose body are provided with two hexagonal connecting nuts for installing the braided hose body. A screw ring is fitted onto the surface of the braided hose body. The screw ring is fitted onto the surface of two hexagonal connecting nuts. Each of the two hexagonal connecting nuts has a limit ring fixed on its surface. The two limit rings are used to limit the screw ring and prevent it from detaching from the braided hose body. Two screw plates for screwing the two hexagonal connecting nuts are fixed on the surface of the screw ring. A set of positioning components is provided inside the screw ring. The positioning components are used to fix the screw ring to the surface of the corresponding hexagonal connecting nut. Each of the two hexagonal connecting nuts has a set of limiting components on its surface, and the two sets of limiting components are used to prevent the screw ring from disengaging from the surface of the braided hose body.

[0007] Optionally, the positioning component includes two first grooves formed in two screw plates, each of the two first grooves having a sliding member that slides within it, each of the two sliding members having a locking block fixed at its adjacent ends, each of the six surfaces of the two hexagonal connecting nuts having a locking groove, each of the two locking blocks engaging with the corresponding two locking grooves, each of the two sliding members having a receiving groove, each of the two receiving grooves having a spring, and the two ends of the two springs abutting against the inner walls of the two receiving grooves and the inner walls of the two first grooves respectively via spring seats; The spring's elasticity pushes two locking blocks into their corresponding slots, maintaining the stability of the screw ring on the surface of the hexagonal connecting nut. After screwing a certain distance, even if the screw ring is released and repositioned, it will not detach from the surface of the hexagonal connecting nut, allowing for easy adjustment of the screwing position.

[0008] Optionally, each of the two adjacent ends of the two card blocks is fixed with a semi-circular head, which is used to quickly guide the two card blocks into the card slot.

[0009] Optionally, both ends of the two sliders are fixed with paddles, and the four paddles are used to move the sliders and blocks on both sides away from the two slots.

[0010] Optionally, both of the screw plates have anti-slip textures on their surfaces.

[0011] Optionally, inclined grooves are provided on both the upper and lower sides of the screw ring.

[0012] In this application, the elastic push of the two clips into the corresponding slots can maintain the stability of the ring sleeve on the surface of the hexagonal connecting nut. After turning a certain distance, even if you release and change the position, the ring will not come off the surface of the hexagonal connecting nut. The turning position can be directly changed, making it convenient to turn.

[0013] In this utility model, the double-layer ultra-flexible high-density military standard medium and high pressure braided hose, through the positioning component, pushes the snap-fit ​​part into the slot by the spring, which can keep the relative position of the screw ring and the hexagonal connecting nut stable. During the screwing process, there is no need to hold it for fixation continuously. When switching hands, the screw ring will not shift, thus improving the operation efficiency. This invention features a simple overall structure, requires no complex auxiliary tools, is suitable for single-person operation, and reduces installation difficulty.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0021] Please see Figures 1-4 As shown, this embodiment provides a double-layer ultra-flexible high-density military standard medium and high pressure braided hose, including a braided hose body 1, a screw ring 2, a hexagonal connecting nut 4, a limiting ring 5, and supporting components.

[0022] The braided hose body 1 is made of stainless steel wire using a three-dimensional braiding process, possessing high flexibility and pressure resistance. Each end is connected to a hexagonal connecting nut 4 for securing to external connectors. Limiting rings 5 ​​are fixed to the surface of both hexagonal connecting nuts 4. The outer diameter of the limiting rings 5 ​​is larger than the inner diameter of the screw ring 2, used to axially limit the screw ring 2 and prevent it from detaching from the surface of the hose body 1.

[0023] The screw ring 2 is fitted onto the surface of the braided hose body 1, with its two ends respectively mating with the surfaces of two hexagonal connecting nuts 4. Two symmetrically distributed screw plates 3 are fixed to the outer wall of the screw ring 2. The surface of the screw plates 3 is provided with anti-slip texture to facilitate the operator to apply force to screw it.

[0024] How the positioning component works The screw ring 2 is equipped with a positioning component to maintain its relative position with the hexagonal connecting nut 4. Specifically, each of the two screw plates 3 has a first groove 7, and a sliding member 9 is slidably connected in each first groove 7. A locking block 12 is fixed to the end of the sliding member 9 near the hexagonal connecting nut 4. Correspondingly, each of the six sides of the hexagonal connecting nut 4 has a slot 6, and the locking block 12 can engage with the slot 6.

[0025] The sliding member 9 has a receiving groove 10, and a spring 8 is provided in the receiving groove 10. The two ends of the spring 8 abut against the inner wall of the receiving groove 10 and the inner wall of the first groove 7 respectively through spring seats, and always provide outward elastic force to push the locking block 12 into the corresponding locking groove 6.

[0026] To facilitate the smooth entry of the locking block 12 into the slot 6, a semi-circular head 11 is fixed to the end of the locking block 12 near the hexagonal connecting nut 4. The semi-circular head 11 has a beveled or arc-shaped structure, which can guide the locking block 12 to align with the slot 6. The upper and lower sides of the screw ring 2 are provided with inclined grooves 13.

[0027] Improvements based on Example 1: See Appendix Figure 1 - Appendix Figure 4 A double-layer ultra-flexible high-density military-standard medium-high pressure braided hose is provided. Both hexagonal connecting nuts 4 have limiting components on their surfaces. These limiting components cooperate with limiting rings 5 ​​to further prevent the tightening ring 2 from falling off the surface of the hose body 1. When it is necessary to adjust the tightening position of the hexagonal connecting nuts 4, the operator can move the levers 14 fixed at both ends of the sliding member 9, causing the sliding member 9 to slide into the first groove 7, driving the locking block 12 to disengage from the locking groove 6. At this time, the tightening ring 2 can move along the surface of the hose body 1 to the hexagonal connecting nut 4 at the other end. Repeating the above positioning process completes the repositioning operation.

[0028] It should be noted that in the description of this specification, descriptions such as "first" and "second" are only used to distinguish the features and do not have any actual order or directional meaning. This application is not limited to this.

[0029] The accompanying drawings in this application are for illustrative purposes only.
