Description

Technical Field

[0001] This application relates to carpet needles, and particularly to a protection mechanism for high-carbon steel carpet needles. Background Art

[0002] In the carpet manufacturing industry, the quality of the needles plays a crucial role in the overall quality and durability of the carpet. Therefore, manufacturers generally choose high-carbon steel as the material for making the needles. High-carbon steel is a special treated steel with a relatively high carbon content, which makes it harder and stronger than ordinary steel. This property of high hardness and strength enables high-carbon steel needles to maintain their sharpness and structural integrity when facing the repetitive and high-intensity pressure during the carpet weaving process. Under the continuous piercing and pulling of the knitting machine, the high-carbon steel needles are not easily bent or broken, thus ensuring that each yarn can be accurately placed in the predetermined position, guaranteeing the accuracy of the carpet pattern and the uniformity of the texture.

[0003] However, when the storage environment of high-carbon steel needles is relatively humid, the high-carbon steel needles are extremely prone to rust. Before storage, it is usually necessary to manually apply oil to the high-carbon steel needles to prevent corrosion. And due to the easy volatilization of the oil, it is necessary to regularly maintain the high-carbon steel needles during storage. These anti-corrosion measures undoubtedly increase the difficulty and cost of storage. Therefore, although high-carbon steel needles exhibit excellent mechanical properties in carpet manufacturing, problems such as insufficient corrosion resistance, high maintenance requirements, and demanding storage conditions cannot be ignored. Summary of the Utility Model

[0004] In order to solve the problems of insufficient corrosion resistance, high maintenance requirements, and demanding storage conditions of high-carbon steel needles in the prior art, this application provides a protection mechanism for high-carbon steel carpet needles, and the specific solution is as follows:

[0005] A protection mechanism for high-carbon steel carpet needles includes a protection tube and a protection cap threadedly connected to the first end of the protection tube. A thin film vesicle is provided inside the protection cap, and an anti-corrosion liquid is provided inside the thin film vesicle. A fastening ring is fixedly provided at the second end of the protection tube, and the protection tube can be fixedly connected to an external high-carbon steel needle through the fastening ring.

[0006] Preferably, an elastic circular fastening limiting layer is fixedly provided inside the protection tube, and the fastening limiting layer includes a plurality of sector-shaped extrusion pieces.

[0007] Preferably, a conical limiting cavity is provided at the inner bottom of the protection cap.

[0008] Preferably, a frustum-shaped accommodation cavity is provided at the inner bottom of the protective cover. A frustum-shaped limiting block is provided in the accommodation cavity. A frustum-shaped limiting hole is formed at the axis of the limiting block. The limiting block is movably connected to the protective cover and is limited by the accommodation cavity. A placement area for placing the thin film vesicle is formed between the limiting block and the inner bottom of the protective cover.

[0009] Preferably, the limiting block is provided with a plurality of diversion holes.

[0010] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0011] 1. By providing a protective tube and a protective cover, on the one hand, the contact between the inserted high-carbon steel acupuncture needle and the external air is reduced, the corrosion and oxidation of the acupuncture needle are slowed down, and it is easy to store. On the other hand, the high-carbon steel acupuncture needle pierces the thin film vesicle provided in the protective cover, so that the anti-corrosion liquid covers the high-carbon steel acupuncture needle, further slowing down the corrosion and oxidation of the acupuncture needle. At the same time, since the protective cover is threadedly connected to the protective tube, when reuse is required, only the protective cover needs to be removed and the thin film vesicle is placed, and it can be used again, saving costs. In addition, the setting of the fastening ring makes the anti-corrosion liquid not easily flow out of the protective tube, reduces the volatilization of the anti-corrosion liquid, and reduces the need for later maintenance.

[0012] 2. The extrusion of the extrusion sheet can further fix and limit the high-carbon steel acupuncture needle.

[0013] 3. By providing a conical limiting cavity to limit the acupuncture part of the high-carbon steel acupuncture needle, on the one hand, it avoids the high-carbon steel acupuncture needle from shaking in the protective tube, making the protective tube more stably fixed to the high-carbon steel acupuncture needle. On the other hand, the wrapping of the acupuncture part can play a protective role.

[0014] 4. Through the cooperation of the accommodation cavity and the limiting block, the acupuncture part of the high-carbon steel acupuncture needle is limited. On the one hand, it avoids the high-carbon steel acupuncture needle from shaking in the protective tube, making the protective tube more stably fixed to the high-carbon steel acupuncture needle. On the other hand, it avoids the acupuncture part from piercing the protective cover due to excessive insertion of the high-carbon steel acupuncture needle. The non-direct contact between the acupuncture part and the protective cover can also reduce the probability of damage to the acupuncture part when the protective cover is impacted.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present application.

[0024] Embodiment 1

[0025] Refer to Figure 1 and Figure 2, A high-carbon steel needle protection mechanism for carpets, comprising a protection tube 1 and a protection cover 2 threadedly connected to the first end of the protection tube 1. A thin film vesicle 3 is provided inside the protection cover 2, and an anti-corrosion liquid is provided inside the thin film vesicle 3. A fastening ring 4 is fixedly provided at the second end of the protection tube 1, and the protection tube 1 can be fixedly connected to a high-carbon steel needle 100 through the fastening ring 4. When in use, the high-carbon steel needle 100 is inserted into the protection tube 1, and the needle part 101 of the high-carbon steel needle 100 partially exposes from the first end of the protection tube 1. At this time, the protection cover 2 is threadedly connected to the first end of the protection tube 1 and screwed into the protection cover 2. As the protection cover 2 is screwed in, the needle part 101 pierces the thin film vesicle 3, and the anti-corrosion liquid inside the thin film vesicle 3 flows out. Alternatively, the protection cover 2 can be first threadedly connected to the first end of the protection tube 1, and then the high-carbon steel needle 100 is inserted into the protection tube 1 and the thin film vesicle 3 is pierced. After piercing the thin film vesicle 3, the high-carbon steel needle 100 can be shaken to evenly cover the inserted part of the high-carbon steel needle 100 with the anti-corrosion liquid. Due to the presence of the fastening ring 4, the anti-corrosion liquid cannot flow out of the protection tube 1, slowing down the volatilization of the anti-corrosion liquid and reducing the maintenance requirements.

[0026] Specifically, referring to Figure 3 , An elastic circular fastening limit layer 5 is fixedly provided inside the protection tube 1. The fastening limit layer 5 includes a plurality of fan-shaped pressing pieces 51. After the high-carbon steel needle 100 passes through the fastening limit layer 5, it is pressed by the pressing pieces 51 to further fix and limit the high-carbon steel needle 100.

[0027] Specifically, referring to Figure 2 , A conical limit cavity 21 is provided at the inner bottom of the protection cover 2. The conical limit cavity 21 can limit the needle part 101 of the high-carbon steel needle 100. On the one hand, it prevents the high-carbon steel needle 100 from shaking inside the protection tube 1, making the protection tube 1 more stably fixed to the high-carbon steel needle 100. On the other hand, the wrapping of the needle part 101 can play a protective role.

[0028] Embodiment 2

[0029] Referring to Figure 4 and Figure 5 , A high-carbon steel needle protection mechanism for carpets, comprising a protection tube 1 and a protection cover 2 threadedly connected to the first end of the protection tube 1. A thin film vesicle 3 is provided inside the protection cover 2, and an anti-corrosion liquid is provided inside the thin film vesicle 3. A fastening ring 4 is fixedly provided at the second end of the protection tube 1, and the protection tube 1 can be fixedly connected to an external high-carbon steel needle 100 through the fastening ring 4.

[0030] Specifically, referring to Figure 3 , An elastic circular fastening limit layer 5 is fixedly provided inside the protection tube 1. The fastening limit layer 5 includes a plurality of fan-shaped pressing pieces 51.

[0031] Specifically, referring toFigure 5 , a frustum-shaped accommodation cavity 22 is provided at the inner bottom of the protective cover 2. A frustum-shaped limiting block 23 is provided in the accommodation cavity 22. A frustum-shaped limiting hole is formed at the axis of the limiting block 23. The limiting block 23 is movably connected to the protective cover 2 and is limited by the accommodation cavity 22. A placement area for placing the thin film vesicle 3 is formed between the limiting block 23 and the inner bottom of the protective cover 2. The accommodation cavity 22 and the limiting block 23 cooperate to limit the acupuncture part 101 of the high-carbon steel acupuncture needle 100. On the one hand, it avoids the high-carbon steel acupuncture needle 100 from shaking in the protective tube 1, making the protective tube 1 more stably fixed to the high-carbon steel acupuncture needle 100. On the other hand, it avoids the acupuncture part 101 of the high-carbon steel acupuncture needle 100 from being over-inserted and piercing the protective cover 2. At the same time, since the acupuncture part 101 and the protective cover 2 are not in direct contact and are protected by the limiting block 23, the probability of damage to the acupuncture part 101 caused by accidental dropping is effectively reduced, and the loss caused by transportation and handling is reduced.

[0032] Specifically, the limiting block 23 is provided with a plurality of diversion holes, which help the anti-corrosion liquid to flow into the protective tube 1 for easy use.

[0033] In summary, the high-carbon steel acupuncture needle protection mechanism for carpets in this application can protect the high-carbon steel acupuncture needle for a long time, avoid the high-carbon steel acupuncture needle from being corroded, and does not require harsh storage conditions, nor frequent maintenance in the later stage. At the same time, the high-carbon steel acupuncture needle protection mechanism for carpets is simple to use and has high efficiency. Therefore, the high-carbon steel acupuncture needle protection mechanism of this application can efficiently solve the problems of insufficient corrosion resistance, high maintenance requirements and harsh storage conditions of high-carbon steel acupuncture needles.
