Description

Technical Field

[0001] The present application relates to a felting needle for a carpet, and in particular to a protective mechanism for a felting needle for a carpet. Background Art

[0002] In carpet manufacturing, the quality of felting needles plays a vital role in the overall quality and durability of the carpet. High-carbon steel is widely used as a felting needle material for carpets due to its high hardness and strength. This high carbon content imparts the needles with the necessary resistance to wear and deformation during the weaving process, ensuring the accuracy of the carpet pattern and uniformity of the texture.

[0003] However, a major drawback of high-carbon steel is its susceptibility to corrosion, especially in humid environments. Existing protective measures often involve protecting the needles with protective tubes. However, because carpet needles have a bend and consist of three parts of varying thickness and length, most protective tubes can only protect a portion of the needle, while the remaining exposed part is easily damaged by bumps, and contact with air also accelerates the corrosion process. In addition, existing protective sleeves are usually tightly fitted with the needles to protect them, making them difficult to remove. However, when selecting a needle, it is necessary to determine the needle type by observing the shape of the needle head. Therefore, the protective sleeve must be removed when selecting a needle, making it difficult to select the needle, thereby affecting production efficiency and the smoothness of the workflow. At the same time, frequent removal and assembly of the protective sleeve also damages the protective sleeve itself, affecting the protective effect. Therefore, the market currently lacks a protective mechanism that can fully protect the needles and can easily and quickly identify the needle type. Utility Model Content

[0004] In order to solve the problems in the prior art of being unable to fully protect the felting needles and the difficulty in identifying the needle types, the present application provides a carpet felting needle protection mechanism, the specific solution is as follows:

[0005] A carpet needle protection mechanism comprises, from bottom to top, a protective sleeve, a first protective tube detachably connected to the protective sleeve via a fixing member, a second protective tube movably connected to the first protective tube, and a sealing cap movably disposed on the top end of the second protective tube, wherein the inner diameter of the protective sleeve is smaller than the inner diameter of the first protective tube, and the inner diameter of the first protective tube is smaller than the inner diameter of the second protective tube;

[0006] The top of the protective tube is provided with a flange protruding outward, the fixing piece is provided with a through hole corresponding to the second protective tube, the fixing piece is detachably connected to the second protective tube, and the fixing piece is further provided with a limiting portion, which limits and fixes the flange when the fixing piece is tightly connected to the second protective tube;

[0007] The second protective tube includes a first tube body, a telescopic tube body and a second tube body from bottom to top. The first tube body is fixedly connected to the second tube body through the telescopic tube body. The telescopic tube body can be bent and telescoped.

[0008] Preferably, the upper end of the sleeve has a first annular bending portion bent outward and downward, and a second annular bending portion extended from the first annular bending portion and then bent upward again to form a first limiting groove is formed below the first annular bending portion, the lower end of the first protective tube has a third annular bending portion bent inward and upward, and a fourth annular bending portion extended from the third annular bending portion and then bent downward again to form a second limiting groove is formed above the third annular bending portion, the first limiting groove limits and fixes the fourth annular bending portion, and the second limiting groove limits and fixes the second annular bending portion.

[0009] Preferably, the telescopic tube has a plurality of folded portions.

[0010] Preferably, the telescopic tube has a zigzag compressed folding structure.

[0011] Preferably, the fixing member is threadedly connected to the second protective tube.

[0012] Preferably, the sealing cover is threadedly connected to the second protection tube.

[0013] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0014] 1. By providing the protective sleeve, the first protective tube, the second protective tube and the sealing cover, the needle can be fully wrapped, making the needle resistant to bumps and corrosion, thus achieving all-round protection for the needle;

[0015] 2. The first protective tube is detachably connected to the protective cylinder via a fixing member. On the one hand, it is convenient to remove the protective cylinder to observe the shape of the needle tip, and the protective cylinder can be replaced after observation without causing any damage. On the other hand, since the protective cylinder is detachable, only a separate protective cylinder needs to be designed, which reduces costs. For example, the protective cylinder can be made of a material with high hardness and high light transmittance to focus on protecting the needle tip. At the same time, the shape of the needle tip can be efficiently observed to determine the type of the needle. In summary, the detachable protective cylinder facilitates the determination of the needle type and also facilitates the realization of further protection requirements for the needle tip.

[0016] 3. The telescopic tube is bendable and retractable, so that it can adapt to the bending part of the needle, which is beneficial to the all-round protection of the needle;

[0017] 4. Since most needles have three parts of different thicknesses, the inner diameter of the protective sleeve is made smaller than that of the first protective tube, and the inner diameter of the first protective tube is made smaller than that of the second protective tube. This can better fit the shape of the needle, reduce internal gas, and enhance the needle's antioxidant capacity.

[0018] 5. By providing the first annular bend portion, the second annular bend portion, the first limiting groove, the third annular bend portion, the fourth annular bend portion and the second limiting groove, the first protective tube and the second protective tube can be detachably connected. On the one hand, it is easy to disassemble and the cost is low. On the other hand, it can ensure good airtightness during connection, which is beneficial to the protection of the puncture needle.

The inner diameter of the protection sleeve 1 is smaller than the inner diameter of the first protection tube 2, and the inner diameter of the first protection tube 2 is smaller than the inner diameter of the second protection tube 3.

[0028] See also Figure 1 and Figure 2 The top of the protective tube 1 is provided with a flange 10 protruding outward, the fixing member 4 is provided with a through hole corresponding to the second protective tube 3, the fixing member 4 is detachably connected to the second protective tube 3, and the fixing member 4 is further provided with a limiting portion 41. When the fixing member 4 is tightly connected to the second protective tube 3, the limiting portion 41 limits and fixes the flange 10;

[0029] See also Figure 1 and Figure 4 The second protective tube 3 includes a first tube body 301, a telescopic tube body 302 and a second tube body 303 from bottom to top. The first tube body 301 is fixedly connected to the second tube body 303 through the telescopic tube body 302, and the telescopic tube body 302 can be bent and telescoped.

[0030] Specifically, refer to Figure 1 and Figure 3The upper end of the sleeve 1 has a first annular bent portion 21 that bends outward and downward, and a second annular bent portion 22 that extends from the first annular bent portion 21 and bends upward again. A first retaining groove 211 is formed below the first annular bent portion 21. The lower end of the first protective tube 2 has a third annular bent portion 31 that bends inward and upward, and a fourth annular bent portion 32 that extends from the third annular bent portion 31 and bends downward again. A second retaining groove 311 is formed above the third annular bent portion 31. The first retaining groove 211 retains and secures the fourth annular bent portion 32, while the second retaining groove 311 retains and secures the second annular bent portion 22. The combination of the first retaining groove 211 and the fourth annular bent portion 32, combined with the second retaining groove 311 and the second annular bent portion 22, ensures airtightness at the connection between the first and second protective tubes 2 and 3, reduces gas ingress, and thus enhances protection for the needle.

[0031] Specifically, the telescopic tube 302 has a plurality of folded portions.

[0032] Specifically, the telescopic tube 302 has a zigzag compressed folding structure, which is convenient for bending and telescoping.

[0034] Specifically, the sealing cover 5 is threadedly connected to the second protection tube 3 .

[0035] During actual use, the needle is fully enclosed by the protective sleeve 1, the first protective tube 2, the second protective tube 3, and the sealing cap 4, which greatly reduces contact with air, enhances the needle's corrosion resistance, and reduces damage to the needle from bumps. When selecting a needle, the protective sleeve 1 can be removed by simply loosening the fixing member 4, thereby determining the needle type. Furthermore, the removable protective sleeve 1 allows the protection requirements of the needle head to be met by simply designing the protective sleeve 1 separately. For example, the protective sleeve 1 can be made of a special material or designed with a different shape according to the different types of needles. The separate design of the protective sleeve 1 reduces design difficulty and saves costs.

[0036] In summary, the carpet needle protection mechanism of the present application can fully reduce the contact between the needles and air, and can fully resist bumps. At the same time, the protective sleeve 1 is easy to remove, which facilitates the identification of the needle type. Therefore, the carpet needle protection mechanism of the present application can solve the problems of the prior art in not being able to fully protect the needles and the difficulty in identifying the needle type.
