Stretchable high strength corrosion resistant spring steel wire protection sleeve

Abstract

This utility model discloses a stretchable, high-strength, corrosion-resistant spring steel wire protective sleeve, comprising a spring steel wire sleeve, the outer surface of which is covered with a corrosion-resistant polymer material. One end of the spring steel wire sleeve is fixedly connected to a connector, which has rectangular through holes spaced evenly in the circumferential direction. A sliding block is slidably connected within the rectangular through holes of the connector, and an elastic element is fixedly connected between the sliding block and the connector. A wedge block is fixedly connected to the sliding block, and a threaded sleeve is threadedly connected to the connector. A rotating ring is rotatably connected to the threaded sleeve, and circumferentially spaced compression blocks are fixedly connected to the inner side of the rotating ring. By rotating the threaded sleeve, the compression blocks are driven, forcing the wedge blocks to drive the sliding blocks to radially press against the outer wall of the pipeline. Combined with the continuous tension of the elastic element, a dynamic rigid connection between the sleeve and the pipeline is achieved. This significantly improves protective stability and is particularly suitable for vibration or moving conditions.

Description

Technical Field

[0001] This utility model relates to the field of protective sleeve technology, and more specifically, to a stretchable high-strength anti-corrosion spring steel wire protective sleeve. Background Technology

[0002] Spring wire protective sleeves, also known as spring wire sheaths, are elastic sheaths made of steel wire. In various industrial machinery, automated equipment, and hydraulic and pneumatic systems, the protection of moving parts is crucial. Precision components exposed to harsh working conditions for extended periods, such as piston rods of hydraulic or pneumatic cylinders, are highly susceptible to contamination, corrosion, or mechanical damage. This not only directly affects the operational accuracy and efficiency of the equipment but also significantly shortens the service life of core components. To address this widespread protection challenge, spring wire sheaths were developed and have been widely used. However, existing spring wire sheaths still have the following problems when adapted to different applications:

[0003] Currently widely used wire mesh protective sleeves are simply designed to be fitted over pipelines without an effective securing mechanism. In actual use, the sleeve is prone to relative sliding or displacement with the pipeline body. This unintended movement not only weakens the sleeve's physical protective barrier effect but can also cause accelerated wear on the pipeline or the sleeve itself due to friction, severely impacting its protective effect and service life. Furthermore, existing wire mesh protective sleeves are generally designed as fixed-length independent units, lacking the ability to connect to each other. When the length of the pipeline to be protected exceeds the coverage of a single sleeve, it is impossible to easily extend the line by connecting multiple sleeves end-to-end. This design flaw significantly limits the flexibility of the sleeve's application, especially in scenarios requiring coverage of long pipelines or adaptation to equipment of different sizes, causing considerable inconvenience to users.

[0004] In view of this, we propose a stretchable high-strength corrosion-resistant spring steel wire protective sleeve. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a stretchable high-strength corrosion-resistant spring steel wire protective sleeve, which has the following beneficial effects:

[0018] 1. This utility model drives the extrusion block by rotating the threaded sleeve, forcing the wedge block to drive the sliding block to radially press against the outer wall of the pipeline. Combined with the continuous tension of the elastic element, a dynamic rigid connection between the sleeve and the pipeline is achieved.

[0020] 3. This utility model forms a self-resetting locking mechanism through a limiting structure and a compression spring: after adjusting the clamping force and releasing the sliding ring, the limiting rod automatically inserts into the limiting hole of the threaded sleeve, rigidly preventing the threaded sleeve from rotating unexpectedly.

The connector 2 is provided with a limit structure. The other end of the spring steel wire sleeve 1 is provided with a plug-in structure.

[0032] Please see Figure 2 and Figure 3 The present invention is further configured such that the limiting structure includes a fixed ring 9, which is fixedly connected to the connector 2. The connector 2 is splinedly connected to a sliding ring 10, and the sliding ring 10 is fixedly connected to a limiting rod 11 with equal circumferential spacing. A threaded sleeve 6 is provided with a limiting hole 16 with equal circumferential spacing on the side near the sliding ring 10, and the limiting rod 11 is inserted into the limiting hole 16 of the threaded sleeve 6. A compression spring 12 is fixedly connected between the fixed ring 9 and the sliding ring 10.

[0033] Please see Figure 3 and Figure 6 The plug-in structure includes a fixed seat 13, which is fixed to the spring steel wire sleeve 1. The fixed seat 13 is threadedly connected to a threaded component 14, which is fixedly connected to a limiting tube 15. The limiting tube 15 is provided with limiting holes 16 distributed circumferentially at equal intervals, and the number of limiting holes 16 is the same as the number of sliding blocks 3. The connector 2 is provided with guide grooves 17 distributed circumferentially at equal intervals, and the number of guide grooves 17 is the same as the number of sliding blocks 3. The threaded component 14 is fixedly connected to guide posts 18 distributed circumferentially at equal intervals, and the guide posts 18 are plugged into the guide grooves 17.

[0034] The working principle of this utility model:

[0035] When using this protective sleeve, place the sleeve on the pipeline, then adjust the position of the spring steel wire sleeve 1. Rotate the threaded sleeve 6, which moves along the connector 2. The threaded sleeve 6 drives the rotating ring 7 to move along the connector 2. The rotating ring 7 drives the pressing block 8 on it to press against the wedge block 5. The wedge block 5 drives the sliding block 3 to slide along the rectangular through hole, stretching the elastic element 4. The sliding block 3 presses against the outer wall of the pipeline, thus connecting the spring steel wire sleeve 1 to the pipeline through the sliding block 3, connecting the spring steel wire sleeve 1 to the designated position on the pipeline. When replacement or disassembly is required, simply rotate the threaded sleeve 6 in the opposite direction. The pressing block 8 will no longer press against the wedge block 5, and under the elastic force of the elastic element 4, the sliding block 3 will reset, releasing the pressure on the pipeline.

[0036] Before rotating the threaded sleeve 6, pull the sliding ring 10 first, compress the spring 12, and the sliding ring 10 drives the limiting rod 11 to move. The limiting rod 11 loses contact with the threaded sleeve 6. Then rotate the threaded sleeve 6 to adjust the squeezing force of the sliding block 3 on the pipeline. After the sliding block 3 is fixed, release the sliding ring 10. Under the elastic force of the spring 12, the limiting rod 11 is re-inserted into the limiting hole 16 of the threaded sleeve 6. Through the limiting cooperation between the limiting rod 11 and the threaded sleeve 6, the rotation of the threaded sleeve 6 during use is prevented, which would cause the sliding block 3 to loosen from the pipeline and cause the spring steel wire sleeve 1 to slip.

[0037] When the spring steel wire sleeve 1 needs to be extended, the threaded part 14 is connected to the fixed seat 13, and then the limiting tube 15 is inserted into the adjacent connector 2. After the guide post 18 is inserted into the guide groove 17, the limiting hole 16 is aligned with the adjacent sliding block 3. Then the threaded sleeve 6 is rotated so that the sliding block 3 passes through the limiting hole 16 and is squeezed against the pipeline, thereby connecting the two adjacent spring steel wire sleeves 1 and improving stability.

[0038] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
