Description

Technical Field

[0001] This utility model relates to the field of metal hose technology, specifically an adjustable metal hose. Background Technology

[0002] In industrial pipeline connections, hydraulic systems for mechanical equipment, fluid transport devices, and precision instrument piping layouts, metal flexible hoses are widely used in connection scenarios requiring adaptation to vibration, displacement, or complex paths due to their excellent flexibility, corrosion resistance, and structural strength. Traditional metal flexible hoses are typically fixed-length structures, consisting of a corrugated body and connectors at both ends. Their length is determined during manufacturing and cannot be adjusted according to actual installation or usage requirements. When there are slight changes in the installation space or connection distance, fixed-length metal flexible hoses often fail to provide a precise match, potentially requiring the customization of different lengths, leading to low installation efficiency and increased costs. Therefore, this invention proposes an adjustable metal flexible hose to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable metal hose to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable metal flexible hose, comprising a metal flexible hose, both ends of which are fixedly connected to connecting posts, each connecting post having a sliding cavity, a T-shaped sliding tube slidably connected within the sliding cavity, the connecting post and the T-shaped sliding tube being sealed by a sealing assembly, the connecting post being provided with an adjustment assembly for driving the T-shaped sliding tube to slide out, a fixed ring plate being fixedly connected to the T-shaped sliding tube, and the adjustment assembly being rotatably connected to the fixed ring plate.

[0005] Preferably, the sealing assembly includes a second sealing ring fixed to the inner side of the connecting column and a first sealing ring fixed to the T-shaped sliding tube. The second sealing ring is in close contact with the T-shaped sliding tube, and the first sealing ring is in close contact with the inner wall of the connecting column.

[0006] Preferably, the adjusting assembly includes an external threaded ring fixedly mounted on the connecting column and an internal threaded sleeve that is threadedly engaged with the external threaded ring.

[0007] Preferably, one end of the internal threaded sleeve is fixedly connected to a connecting rod, and one end of the connecting rod is fixedly connected to a rotating ring, which is rotatably connected to a fixed ring plate.

[0008] Preferably, the rotating ring is rotatably engaged with the fixed ring plate through an annular groove, the annular groove being formed on the fixed ring plate, and the rotating ring being embedded in the annular groove and capable of rotating circumferentially along the groove.

[0009] Preferably, there are multiple connecting rods arranged in a circular array between the internal threaded sleeve and the rotating ring.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] By setting up a cooperative structure between the adjustment component and the T-shaped sliding tube, the T-shaped sliding tube can be easily driven to slide within the sliding cavity of the connecting column, realizing flexible adjustment of the overall length of the metal hose. This effectively solves the problem that traditional fixed-length metal hoses are difficult to adapt to small changes in installation space or connection distance, significantly improving installation efficiency and reducing customization costs. The tight contact design between the first sealing ring and the inner wall of the connecting column, and between the second sealing ring and the T-shaped sliding tube in the sealing component, ensures a reliable seal throughout the sliding process of the T-shaped sliding tube, avoiding the risk of fluid leakage and ensuring the sealing and safety of the pipeline system.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0018] Please see Figures 1 to 4This utility model provides a technical solution: an adjustable metal flexible hose, including a metal flexible hose 1. The metal flexible hose 1 adopts a corrugated pipe structure with high flexibility. Both ends of the hose are fixed with connecting posts 2 by welding. The connecting posts 2 have a sliding cavity 4 adapted to a T-shaped sliding tube 5. The inner wall of the sliding cavity 4 is precision ground to ensure that the T-shaped sliding tube 5 can slide smoothly. The T-shaped sliding tube 5 is slidably connected in the sliding cavity 4. The diameter of the head of the T-shaped sliding tube 5 is larger than the diameter of the rod, which can effectively prevent it from detaching from the sliding cavity 4 during sliding. The connecting posts 2 and the T-shaped sliding tube 5 are sealed by a sealing component 6. The connecting posts 2 are provided with an adjusting component 3 for driving the T-shaped sliding tube 5 to slide out. A fixing ring plate 7 is welded and fixed to the T-shaped sliding tube 5. The fixing ring plate 7 and the T-shaped sliding tube 5 are coaxially arranged. The adjusting component 3 is rotatably connected to the fixing ring plate 7.

[0019] like Figure 2 As shown, the sealing assembly 6 includes a second sealing ring 62 fixed to the inner side of the connecting column 2 and a first sealing ring 61 fixed to the T-shaped sliding tube 5. Both are made of oil-resistant and heat-resistant fluororubber. The second sealing ring 62 is in close contact with the T-shaped sliding tube 5, and the first sealing ring 61 is in close contact with the inner wall of the connecting column 2, forming a double sealing structure to improve the sealing effect. The design of the first sealing ring 61 in close contact with the inner wall of the connecting column 2 and the second sealing ring 62 in close contact with the T-shaped sliding tube 5 in the sealing assembly 6 ensures a reliable seal during the sliding process of the T-shaped sliding tube 5, avoiding the risk of fluid leakage.

[0020] like Figure 4 As shown, the adjusting component 3 includes an external threaded ring 34 welded to the connecting column 2 and an internal threaded sleeve 31 that is threadedly engaged with the external threaded ring 34. A connecting rod 32 is welded to one end of the internal threaded sleeve 31, and a rotating ring 33 is welded to one end of the connecting rod 32. The rotating ring 33 is rotatably connected to the fixed ring plate 7. By setting the cooperating structure between the adjusting component 3 and the T-shaped sliding tube 5, the T-shaped sliding tube 5 can be easily driven to slide in the sliding cavity 4 of the connecting column 2, so as to realize the flexible adjustment of the overall length of the metal hose 1.

[0021] like Figure 4 As shown, the rotating ring 33 is rotatably engaged with the fixed ring plate 7 through an annular groove. The annular groove is formed on the fixed ring plate 7. The rotating ring 33 is embedded in the annular groove and can rotate around the groove. There are multiple connecting rods 32, and multiple connecting rods 32 are arranged in annular array between the internal threaded sleeve 31 and the rotating ring 33.

[0022] When the adjustable metal hose 1 needs to be extended, the inner threaded sleeve 31 in the adjusting assembly 3 is rotated, causing it to rotate along the thread direction on the outer threaded ring 34. Since the outer threaded ring 34 is fixedly installed on the connecting post 2, the rotation of the inner threaded sleeve 31 is converted into axial movement, which in turn drives the connecting rod 32 and the rotating ring 33 to move synchronously. The rotating ring 33 is rotatably connected to the fixed ring plate 7 on the T-shaped sliding tube 5, thus pushing the T-shaped sliding tube 5 to slide outward in the sliding cavity 4 inside the connecting post 2. During this process, the first sealing ring 61 in the sealing assembly 6 moves with the T-shaped sliding tube 5 and is always in close contact with the inner wall of the connecting post 2. The second sealing ring 62 is fixed on the inner side of the connecting post 2 and is always in close contact with the T-shaped sliding tube 5, ensuring the sealing during the sliding process. This achieves the overall length extension adjustment of the metal hose 1, which is simple to operate and can stably maintain the adjusted length, making it easy to adjust flexibly according to actual needs.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
