Technical Field

[0001] This utility model relates to the field of rust-proof bags, specifically to a puncture-resistant vapor phase rust-proof bag. Background Technology

[0002] Rust-proof bags are specially designed to protect metal products from oxidation and corrosion. They are suitable for the storage, transportation and packaging of various industrial products, such as automotive parts, machine tool accessories, bearings, pipes, and mechanical parts. Their rust-proof period can be more than 2 years. They are also easy to use; simply put the metal products directly into the bag and seal it. This can reduce equipment damage and maintenance costs during production and transportation.

[0003] The existing rust-proof bags still have the following problems when used: the existing rust-proof bags are inconvenient to store, and the bags may be punctured when they come into contact with sharp objects, affecting the subsequent use of the rust-proof bags and causing unnecessary economic losses to enterprises.

[0004] Therefore, it is necessary to invent a puncture-resistant vapor phase rust-preventing bag to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a puncture-resistant vapor phase rust inhibitor bag to solve the problems mentioned in the background art, such as the inconvenience of storing existing rust inhibitor bags during use, and the possibility of the bag being punctured when it comes into contact with sharp objects, affecting the subsequent use of the rust inhibitor bag and causing unnecessary economic losses to enterprises.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a puncture-resistant vapor phase rust-preventive bag, comprising a storage tube, wherein a storage cavity is formed inside the storage tube, and an opening is formed inside the tube body, the opening communicating with the storage cavity; a rotating shaft is rotatably connected inside the storage tube, and one end of the bag body is fixedly connected to the outer wall of the rotating shaft; and a sealing strip is installed at the other end of the bag body; further comprising:

[0007] The rotating assembly has a threaded rod threaded to the end of the receiving tube, and a limit block is fixedly connected to the outer ring of the threaded rod. The threaded rod and the limit block move within the pre-reserved columnar groove inside the rotating shaft and the limit groove connected to the columnar groove, which facilitates the rotation of the rotating shaft.

[0008] The stable rotation assembly has a chassis fixedly connected to the lower end of the rotating shaft, and the chassis moves within a pre-reserved annular groove one inside the storage tube. A connecting rod is fixedly connected to the upper end of the rotating shaft, and the connecting rod moves within a pre-reserved annular groove two inside the storage tube, ensuring the stable rotation of the rotating shaft.

[0009] Preferably, the inner walls on both sides of the opening are fixedly connected with blocks, and the outer ring of the blocks is wrapped with flocked cloth, and the flocked cloth is in contact with the outer surface of the bag body to squeeze out the air inside the bag body, ensuring that the bag body can be stored quickly.

[0010] Preferably, the outer diameter of the threaded rod is smaller than the inner diameter of the columnar groove, so that the rotating shaft does not affect the rotation of the threaded rod.

[0011] Preferably, two limiting blocks are provided, and the two limiting blocks are symmetrically fixed to the lower end of the threaded rod with reference to the central axis of the threaded rod as the axis of symmetry. The outer wall of the limiting block is attached to the inner wall of the limiting groove to achieve a sliding connection between the upper and lower parts. The columnar groove reserved inside the rotating shaft and the limiting groove connected to the columnar groove provide space for the threaded rod to move up and down, ensuring that the threaded rod rotates smoothly without obstruction.

[0012] Preferably, the top of the limiting groove is a closed end, and the bottom end of the limiting groove is flush with the bottom of the columnar groove to ensure that the movable connection between the threaded rod and the rotating shaft does not fall off.

[0013] Preferably, the outer diameter of the chassis is larger than the outer diameter of the rotating shaft, and the outer wall of the chassis and the lower end of the rotating shaft are attached to the inner wall of the annular groove to achieve a rotatable connection.

[0014] Preferably, there are two connecting rods, and the two connecting rods are symmetrically distributed with reference to the central axis of the rotation shaft. The two connecting rods form a "7" shape in different directions to ensure the stability of the rotation of the rotation shaft.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] This invention uses a twisting threaded rod to drive a rotating shaft, causing the bag to be rolled up inside the storage cavity. This prevents the rust-proof bag from being torn by sharp objects when not in use, thus ensuring its continued usability. When the threaded rod is rotated, the cylindrical groove and the limiting groove inside the rotating shaft, which have sufficient space, cause the bag to move. The inner diameter of the cylindrical groove is larger than the outer diameter of the threaded rod, so the rotating shaft does not affect the rotation of the threaded rod. At the same time, the rotation of the threaded rod in different directions can also drive the rotation of the rotating shaft to roll up and unroll the bag. The overall operation is convenient and quick. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The illustrated puncture-resistant vapor phase rust-preventive bag includes a receiving tube 1, with a receiving cavity 2 inside the receiving tube 1, and an opening 3 inside the tube body of the receiving tube 1, the opening 3 communicating with the receiving cavity 2. A rotating shaft 4 is rotatably connected inside the receiving tube 1, and one end of a bag body 5 is fixedly connected to the outer wall of the rotating shaft 4. A sealing strip 6 is installed at the other end of the bag body 5. The bag also includes:

[0027] The rotating assembly 7 has a threaded rod 702 threadedly connected to the end of the receiving tube 1, and the outer ring of the threaded rod 702 is fixedly connected to a limiting block 703. The threaded rod 702 and the limiting block 703 move within the pre-reserved columnar groove 701 and the limiting groove 704 connected to the columnar groove 701 inside the rotating shaft 4, which facilitates the rotation of the rotating shaft 4.

[0028] The stable rotation assembly 8 has a chassis 801 fixedly connected to the lower end of the rotating shaft 4, and the chassis 801 moves within the annular groove 802 reserved inside the storage tube 1. The upper end of the rotating shaft 4 is fixedly connected to a connecting rod 803, and the connecting rod 803 moves within the annular groove 804 reserved inside the storage tube 1, ensuring the stable rotation of the rotating shaft 4.

[0029] The inner walls on both sides of the opening 3 are fixedly connected with blocks 9, and the outer ring of the blocks 9 is wrapped with flocked cloth. The flocked cloth is in contact with the outer surface of the bag body 5 to squeeze out the air inside the bag body 5, ensuring that the bag body 5 can be stored quickly.

[0030] The outer diameter of the threaded rod 702 is smaller than the inner diameter of the columnar groove 701, and the rotating shaft 4 does not affect the rotation of the threaded rod 702.

[0031] Two limit blocks 703 are provided, and the two limit blocks 703 are fixedly connected to the lower end of the threaded rod 702 with the central axis of the threaded rod 702 as the axis of symmetry. The outer wall of the limit block 703 is attached to the inner wall of the limit groove 704 to achieve a sliding connection between the upper and lower parts. The columnar groove 701 reserved inside the rotating shaft 4 and the limit groove 704 connected to the columnar groove 701 provide space for the threaded rod 702 to move up and down, ensuring that the threaded rod 702 rotates smoothly without obstruction.

[0032] The top of the limiting groove 704 is a closed end, and the bottom end of the limiting groove 704 is flush with the bottom of the columnar groove 701, ensuring that the movable connection between the threaded rod 702 and the rotating shaft 4 does not fall off.

[0033] The outer diameter of the chassis 801 is larger than the outer diameter of the rotating shaft 4, and the outer wall of the chassis 801 and the lower end of the rotating shaft 4 are attached to the inner wall of the annular groove 802 to achieve a rotating connection.

[0034] There are two connecting rods 803, and the two connecting rods 803 are symmetrically distributed with reference to the central axis of the rotating shaft 4. The two connecting rods 803 present a "7" shape in different directions to ensure the stability of the rotation of the rotating shaft 4.

[0035] Working principle: When using a puncture-resistant vapor phase rust-preventive bag, firstly, the toggle block fixedly connected to the top of the threaded rod 702 is twisted to drive the threaded rod 702 to rotate. The limiting blocks 703 fixedly connected to the two side walls of the lower end of the threaded rod 702 rotate synchronously, driving the rotation shaft 4 to rotate. The bag body 5 fixedly connected to the outer wall of the rotation shaft 4 is rolled up as the rotation shaft 4 rotates, so that the bag body 5 is rolled up inside the storage cavity 2, so that the rust-preventive bag will not be scratched by sharp objects when not in use, affecting subsequent use. Then, the toggle block is twisted in the opposite direction to drive the threaded rod 702 to rotate, and the rotation shaft 4 rotates synchronously. At this time, the reverse rotating shaft 4 unwinds the bag body 5 wrapped around the outer ring of the rotation shaft 4. Then, it can be used by opening the sealing strip 6.

[0036] The threaded rod 702, which is threaded to the end of the storage tube 1, will be displaced when rotated. At the same time, the columnar groove 701 reserved inside the rotating shaft 4 and the limiting groove 704 connected to the columnar groove 701 provide space for the threaded rod 702 to move up and down. The inner diameter of the columnar groove 701 is larger than the outer diameter of the threaded rod 702. In this way, the rotating shaft 4 does not affect the rotation of the threaded rod 702. At the same time, the rotation of the threaded rod 702 can also drive the rotation of the rotating shaft 4 to wind and unwind the bag body 5.

[0037] The lower end of the rotating shaft 4 and the base 801 fixedly connected to the lower end of the rotating shaft 4 rotate inside the annular groove 802. At the same time, the connecting rod 803 fixedly connected to the upper end of the rotating shaft 4 rotates inside the corresponding annular groove 804. This ensures the stability of the subsequent rotation of the rotating shaft 4, ensures the smooth use of the entire rust-proof bag during storage and unrolling, and ensures better storage of the bag body 5 to prevent it from being punctured.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
