Description

Technical Field

[0001] This utility model relates to the field of spring tube assembly technology, specifically an assembled spring tube assembly. Background Technology

[0002] A Bourdon tube is a mechanical elastic element, usually made of metallic materials. It can elastically deform when subjected to external force and then return to its original shape through elastic reaction force. The main function of a Bourdon tube is to absorb mechanical vibration and shock, reduce noise and vibration, thereby protecting mechanical equipment and its components. Bourdon tubes are widely used in machinery, automotive, aviation, aerospace, electronics, instrumentation, and other fields.

[0003] When the spring tubes are not in use, the staff will stack the spring tube assemblies in the warehouse. In order to prevent dust and oil stains from adhering to the surface of the spring tubes, the staff will wrap the spring tubes with dustproof cloth to achieve the purpose of dust prevention. However, this method of wrapping the spring tubes with dustproof cloth is not only cumbersome to operate, but also requires a lot of manpower to remove the dustproof cloth, resulting in a waste of resources.

[0004] Therefore, this utility model provides an assembled spring tube assembly to solve the above problems. Utility Model Content

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: This utility model provides an assembled spring tube assembly, such as... Figure 1-5 As shown, the spring tube assembly includes a top plate 1 and a bottom plate 2. A spring tube body 3 and a telescopic rod 4 are fixedly installed between the top plate 1 and the bottom plate 2. The telescopic rod 4 is located inside the spring tube body 3. A storage tube 11 surrounding the spring tube body 3 is fixedly installed on the top of the bottom plate 2. A plastic corrugated tube 12 is fixedly installed on the top of the bottom plate 2 inside the storage tube 11. A pull ring 13 is fixedly installed on the top of the plastic corrugated tube 12. A snap-fit ​​assembly is fixedly provided between the pull ring 13 and the top plate 1. The snap-fit ​​assembly is used to flexibly install the pull ring 13 onto the top plate 1. When the pull ring 13 is snapped together with the top plate 1, the plastic corrugated tube 12 will wrap around the spring tube body 3 without contacting the spring tube body 3.

[0021] In Embodiment 2, based on Embodiment 1, the snap-fit ​​assembly includes two fixing blocks 19 fixedly installed at the bottom of the top plate 1. The bottom of the fixing block 19 has a slot 20. The inner walls of the slot 20 have grooves 21 on both sides. A compression spring 22 is fixedly installed inside the groove 21. An arc-shaped block 23 is fixedly installed at one end of the compression spring 22. Two snap-fit ​​blocks 14 that match the fixing blocks 19 are fixedly installed on the top of the pull ring 13. The snap-fit ​​blocks 14 can be movably inserted into the slot 20, and arc-shaped grooves 16 that match the arc-shaped blocks 23 are opened on both sides of the snap-fit ​​blocks 14.

[0022] In Example 3, based on Example 1, a lever 15 is fixedly installed on both sides of the pull ring 13, a second magnetic block 18 is fixedly installed on the side of the lever 15, and a first magnetic block 17 that attracts the second magnetic block 18 is fixedly installed on both sides of the storage tube 11. The pull ring 13 can be fixed to the top of the storage tube 11 by the first magnetic block 17 and the second magnetic block 18.

[0023] In Example 4, based on Example 1, a circular groove 5 is provided on the top of the top plate 1, and an internal thread groove 8 is provided on the inner wall of the circular groove 5. Four bolts 10 are movably inserted into the periphery of the top plate 1.

[0024] In Example 5, based on Example 4, a round tube 6 is fixedly installed on the bottom of the base plate 2. The circumference of the round tube 6 is provided with an external thread groove 7 that is compatible with the internal thread groove 8. The round tube 6 is threadedly connected to the round groove 5 through the external thread groove 7. Multiple spring tube assemblies can be spliced ​​and installed together through the internal thread groove 8 and the external thread groove 7.

[0025] In Example 6, based on Example 5, the circumference of the round tube 6 is provided with a screw hole that matches the bolt 10. After the round tube 6 is fully inserted into the round groove 5, the bolt 10 can be inserted into the screw hole. The threaded connection between the bolt 10 and the screw hole can improve the stability between the round tube 6 and the round groove 5.

[0026] In Example 7, based on Example 1, multiple equally spaced mounting plates 9 are fixedly installed on the periphery of both the top plate 1 and the bottom plate 2, allowing the entire device to be installed onto mechanical equipment via the mounting plates 9.

[0027] In Example 8, based on Example 3, when the first magnetic block 17 and the second magnetic block 18 are attracted together, the pulling ring 13 is tightly attached to the top of the storage tube 11.

[0028] In Example 9, based on Example 1, the telescopic rod 4 has the same minimum contraction value as the spring tube body 3, so that the telescopic rod 4 will not affect the contraction of the spring tube body 3.

[0029] In Example 10, based on Example 1, a sealing gasket 24 is fixedly installed on the top of the top plate 1. When the top plate 1 is threadedly connected to the bottom plate 2 of another spring tube assembly, the sealing gasket 24 can improve the sealing performance.

[0030] Working principle: When the device is idle and stored in the warehouse, in order to prevent dust and oil stains from adhering to the surface of the spring tube body 3, the staff can hold the lever 15 and lift it upwards. At this time, the first magnetic block 17 will separate from the second magnetic block 18, so that the pull ring 13 can move up and down automatically. Then, the two locking blocks 14 on the top surface of the pull ring 13 are inserted into the slots 20 at the bottom of the corresponding fixing blocks 19. During the process of the locking block 14 entering the slot 20, the arc-shaped block 23 in the slot 20 will first retract into the groove 21. After the locking block 14 is fully entered into the slot 20, the arc-shaped block 23 will pop out from the groove 21 under the action of the compression spring 22 and engage with the arc-shaped grooves 16 on both sides of the locking block 14. In this way, the locking block 14 can be flexibly installed into the fixing block 19. When the pull ring 13 moves up, the plastic corrugated tube 12 at its bottom will open and wrap the spring tube body 3, thereby protecting the surface of the spring tube body 3 from dust. When multiple Bourdon tube assemblies need to be combined together, the worker can screw the round tube 6 on one Bourdon tube assembly into the round groove 5 on another Bourdon tube assembly. After the round tube 6 is fully inserted into the round groove 5, the bolts 10 are screwed in one by one. The bolts 10 will be threaded into the screw holes, thereby improving the stability between the round tube 6 and the round groove 5.

[0031] 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.
