Description

Technical Field

[0001] The present application relates to carpet needles, and particularly to high-carbon steel carpet needle assemblies. Background Art

[0002] In the carpet manufacturing industry, carpet needles are usually made of high-carbon steel. High-carbon steel needles have excellent hardness and strength, which enable them to perform well under repeated weaving pressure and high-load work, thus ensuring the quality and durability of carpet weaving.

[0003] However, despite the significant mechanical property advantages of high-carbon steel needles, they have obvious deficiencies in terms of corrosion resistance, maintenance efficiency, and warehousing convenience. These needles are prone to rust in humid environments and require regular manual oiling to prevent corrosion. This process is not only inefficient but also prone to contamination of the needles due to improper operation. Traditional anti-corrosion measures increase the complexity and cost of warehousing. Therefore, although the advantages of high-carbon steel carpet needles in mechanical properties cannot be ignored, their limitations in terms of corrosion resistance, maintenance, and warehousing urgently need to be overcome through technological innovation to achieve a more efficient, economical, and environmentally friendly carpet production process. Summary of the Utility Model

[0004] In order to solve the problems of easy corrosion and difficult maintenance of carpet needles in warehousing in the prior art, the present application provides a high-carbon steel carpet needle assembly, and the specific solutions are as follows:

[0005] The high-carbon steel carpet needle assembly includes a needle body and an anti-corrosion mechanism. One end of the needle body is bent to form a bent handle, and the other end of the needle body is provided with a needle tip portion; the anti-corrosion mechanism includes a sleeve, an isolation layer, and a fastening ring. The isolation layer is fixed in the sleeve and can be punctured by the needle tip portion. The isolation layer and the inner bottom of the sleeve form a sealed liquid storage cavity, and the liquid storage cavity is provided with anti-corrosion liquid. The needle body can be inserted into the sleeve and is fixedly connected to the sleeve through the fastening ring.

[0006] Preferably, a conical limiting cavity is provided at the inner bottom of the sleeve.

[0007] Preferably, the isolation layer includes a connection layer and a puncture layer. The connection layer is fixed in the sleeve and has a circular opening at the center. The puncture layer is fixedly connected to the connection layer and covers the circular opening.

[0008] Preferably, the thickness of the connection layer is greater than the thickness of the puncture layer.

[0009] Preferably, the fastening ring is fixed at the top of the sleeve and is coaxial with the sleeve.

[0010] Preferably, the lancet body is provided with a positioning groove, and the fastening ring can be limited by the positioning groove.

[0011] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0012] 1. A part of the lancet body is inserted into the sleeve, and the sleeve is fitted with a fastening ring, so that the inserted part of the lancet body is in a closed space, isolating the external air and slowing down the corrosion and oxidation of the lancet; at the same time, when the lancet body is fully inserted into the sleeve, the tip of the lancet body pierces the isolation layer, so that the anti-corrosion liquid in the liquid accommodation cavity flows out and covers the surface of the inserted part of the lancet body, further isolating the air, so as to achieve the anti-corrosion of the lancet. And at this time, the anti-corrosion liquid is in the sleeve, which can slow down the volatilization and is convenient for maintenance; the lancet body is combined with the anti-corrosion mechanism, so that the operator can efficiently solve the problem that the high-carbon steel lancets for carpets are easy to corrode in storage through simple operations, and no complex maintenance is required in the later stage;

[0013] 2. The bottom of the sleeve is provided with a conical limiting cavity, which can limit the tip of the lancet body to protect the tip, especially reduce the damage during transportation and handling. At the same time, the limitation of the tip can reduce the movement of the lancet body relative to the sleeve, thereby avoiding the loosening of the fastening ring;

[0014] 3. The isolation layer includes a connection layer and a puncture layer. On the one hand, the puncture layer is more easily pierced by the tip, which is convenient for use. On the other hand, the circular opening of the connection layer limits the tip to prevent the tip from piercing the sleeve;

[0015] 4. The fastening ring is fixed on the top of the sleeve and is coaxial with the sleeve, which is convenient for the lancet body to be inserted into the sleeve and convenient for operation;

[0016] 5. The positioning groove of the lancet body cooperates with the fastening ring. On the one hand, it can position the insertion depth of the lancet body to prevent the tip from piercing the sleeve. On the other hand, it can fix the sleeve more stably.

Detailed implementation manners

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings of the present application. Obviously, the described embodiments of the present application are only partial embodiments of the present application, rather than all embodiments. 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 of protection of the present application.

[0026] Embodiment 1

[0027] Refer to Figure 1 and Figure 2, The high-carbon steel carpet needle assembly includes a needle body 1 and an anti-corrosion mechanism 2. One end of the needle body 1 is bent to form a bent handle 11, and the other end of the needle body 1 is provided with a needle tip portion 12. The anti-corrosion mechanism 2 includes a sleeve 21, an isolation layer 22 and a fastening ring 23. The isolation layer 22 is fixed in the sleeve 21 and can be punctured by the needle tip portion 12. The isolation layer 22 and the inner bottom of the sleeve 21 form a sealed liquid accommodation cavity 211, and the liquid accommodation cavity 211 is provided with anti-corrosion liquid. The needle body 1 can be inserted into the sleeve 21 and is fixedly connected to the sleeve 21 through the fastening ring 23. After the needle body 1 is inserted into the sleeve 21 and punctures the isolation layer 22, the anti-corrosion liquid flows out from the liquid accommodation cavity 211 and covers the inserted part of the needle body 1. The problem of easy corrosion of the needle body 1 during storage can be solved by a simple insertion operation. In addition, the length of the sleeve 21 can be changed according to storage requirements to support needle bodies 1 of different lengths. At the same time, since the anti-corrosion liquid is confined in the sleeve 21 and is not easy to volatilize, it is easy to maintain during storage and the maintenance cost is reduced.

[0028] Specifically, the fastening ring 23 is fixed on the top of the sleeve 21 and is coaxial with the sleeve 21 for the insertion of the needle body 1.

[0029] Specifically, referring to Figure 3 , the isolation layer 22 includes a connection layer 221 and a puncture layer 222. The connection layer 221 is fixed in the sleeve 21 and has a circular opening at the center. The puncture layer 222 is fixedly connected to the connection layer 221 and covers the circular opening. The connection layer 221 has a certain protective effect on the puncture layer 222 to support a thinner puncture layer 222. At the same time, the connection layer 22 can limit the needle tip portion 12 to prevent the needle tip portion 12 from piercing through the sleeve 21, which is also beneficial to the stable connection between the sleeve 21 and the needle body 1.

[0030] Specifically, the thickness of the connection layer 221 is greater than the thickness of the puncture layer 222.

[0031] Embodiment 2

[0032] Referring to Figure 4 and Figure 5 , the high-carbon steel carpet needle assembly includes a needle body 1 and an anti-corrosion mechanism 2. One end of the needle body 1 is bent to form a bent handle 11, and the other end of the needle body 1 is provided with a needle tip portion 12. The anti-corrosion mechanism 2 includes a sleeve 21, an isolation layer 22 and a fastening ring 23. The isolation layer 22 is fixed in the sleeve 21 and can be punctured by the needle tip portion 12. The isolation layer 22 and the inner bottom of the sleeve 21 form a sealed liquid accommodation cavity 211, and the liquid accommodation cavity 211 is provided with anti-corrosion liquid. The needle body 1 can be inserted into the sleeve 21 and is fixedly connected to the sleeve 21 through the fastening ring 23.

[0033] Specifically, a conical limiting cavity 212 is provided at the bottom of the sleeve 21, and the insulating layer 22 can be arranged in the limiting cavity 212 or above the limiting cavity 212. When the insulating layer 22 is arranged in the limiting cavity 212, the liquid containing cavity 211 is contained in the limiting cavity 212; when the insulating layer 22 is arranged above the limiting cavity 212, the limiting cavity 212 is contained in the liquid containing cavity 211. Figure 5 When the insulating layer 22 is at the critical position of the above two situations, the liquid containing cavity 211 and the limiting cavity 212 are mutually inclusive. The conical limiting cavity 212 can better adapt to the shape of the needle tip 12 so as to limit the needle tip 12, on the one hand to protect the needle tip 12, on the other hand to reduce the movement of the puncture needle body 1 relative to the sleeve 21, thereby avoiding the loosening of the fastening ring 23 as much as possible.

[0034] Specifically, the fastening ring 23 is fixed on the top of the sleeve 21 and is coaxial with the sleeve 21 .

[0035] Specifically, the needle body 1 is provided with a positioning groove, and the fastening ring 23 can be limited by the positioning groove. The positioning groove can position the insertion depth of the needle body 1 to prevent the needle tip 12 from being over-inserted and piercing the sleeve 21, and can more stably fix the sleeve 21 by limiting the position of the fastening ring 23.

[0036] In summary, the high-carbon steel needle assembly for carpets of the present application can effectively resist corrosion, thus adapting to various complex storage environments, and does not require excessive maintenance by warehouse management personnel, thus saving maintenance costs. Therefore, the high-carbon steel needle assembly for carpets of the present application can effectively solve the problem of easy corrosion and difficult maintenance of carpet needles in storage.
