Description

Technical Field

[0001] This utility model belongs to the field of textile steel needle technology, and more specifically, it relates to a textile steel needle that is easy to install. Background Technology

[0002] The steel needles are made of high-carbon steel. The steel wire is cut, sharpened, quenched, and polished with shavings to ensure that its diameter, length, hardness, and surface finish meet the process requirements. The cross-sectional shapes of the steel needles include flat, round, and drum-shaped at the root, among others. The steel needles and the wooden board have a near-static fit. The diameter, length, arrangement, and various specifications of the steel needles are determined according to their intended use.

[0003] Based on the above, the inventors have discovered the following problems: the positioning of textile steel needles in current production is not quick and effective enough, and when workers need to replace textile steel needles, the positioning and installation are inconvenient, which can cause the textile steel needles to get stuck, thus wasting workers' time and effort and affecting work efficiency. In addition, the ordinary installation method can cause the textile steel needles to shake and become unstable during operation, thus affecting textile efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a textile steel needle that is easy to install, in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a textile steel needle that is easy to install, thus solving the problems of inconvenient and quick installation of current textile steel needles, as well as the tendency for ordinary installation methods to cause shaking and instability during operation.

[0006] The purpose and function of this utility model, which provides an easy-to-install textile steel needle, are achieved through the following specific technical means:

[0007] A textile steel needle that is easy to install includes a fixing block, a mounting sleeve at the bottom of the fixing block, a plurality of chambers inside the mounting sleeve, a limiting block in each chamber, a protrusion on one side of the limiting block, and a trapezoidal block connected to the other side of the limiting block via a connecting rod. A movable sleeve is fitted on the outside of the fixing block, a movable ring is movably connected to the bottom of the movable sleeve, and a mounting seat is provided at the bottom of the movable ring. A needle tip is provided at the bottom of the mounting seat.

[0008] Furthermore, a spring is provided on the outer side of the protrusion, one side of the spring is in contact with the inner wall of the cavity, and the other side of the spring is in contact with one side of the limiting block.

[0009] Furthermore, the movable ring has a retaining ring inside.

[0010] Furthermore, the outer side of the fixed block is provided with external threads, and the inside of the movable sleeve is provided with internal threads, and the internal threads and external threads are matched.

[0011] Furthermore, the mounting base is provided with mounting holes around its perimeter, and the mounting holes match the protrusions.

[0012] Furthermore, the mounting base has a set of positioning blocks on its side, and the mounting sleeve has a positioning groove on its side, the positioning groove and the positioning blocks being matched.

[0013] Furthermore, the movable sleeve has auxiliary holes on its periphery, and the needle has a wire outlet hole at its bottom.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By aligning the positioning block with the positioning slot through the cooperation between the positioning block and the positioning slot, quick alignment can be achieved, facilitating subsequent rapid installation.

[0016] 2. By using the engagement of the fixed block, mounting sleeve, limiting block, protrusion block, trapezoidal block, movable sleeve, moving ring, mounting base, spring, retaining ring, external thread, internal thread, and mounting hole, the mounting base at the top of the needle is aligned with the mounting sleeve. Then, the movable sleeve is rotated, and the internal and external threads of the movable sleeve match, causing the movable sleeve to move downwards, which in turn causes the moving ring to move downwards. The retaining ring on the inner side of the moving ring is wider at the bottom and narrower at the top. The downward movement of the retaining ring can cause the trapezoidal block to move into the cavity, allowing the protrusion block to engage inside the mounting hole. Conversely, the retaining ring releases the restriction on the trapezoidal block, allowing the needle to be disassembled. This achieves quick installation and disassembly, which is convenient, fast, and improves work efficiency. At the same time, the engagement of multiple protrusion blocks and mounting holes can fix the mounting base of the needle at multiple angles, improving the stability of the needle.

[0026] Example:

[0027] As attached Figure 1 To be continued Figure 4 As shown:

[0028] This utility model provides a textile steel needle that is easy to install, including a fixing block 1. The bottom of the fixing block 1 is provided with an installation sleeve 2. The installation sleeve 2 has several chambers inside. The chambers are provided with limiting blocks 3. One side of the limiting block 3 is provided with a protrusion block 4. The other side of the limiting block 3 is connected to a trapezoidal block 5 through a connecting rod. The outside of the fixing block 1 is provided with a movable sleeve 6. The bottom of the movable sleeve 6 is movably connected with a moving ring 7, and the bottom of the moving ring 7 is provided with a mounting seat 8. The bottom of the mounting seat 8 is provided with a needle tip 9.

[0029] The outer side of the protrusion 4 is provided with a spring 10, one side of the spring 10 is in contact with the inner wall of the cavity, and the other side of the spring 10 is in contact with one side of the limiting block 3.

[0030] The movable ring 7 has a retaining ring 11 inside.

[0031] The fixed block 1 has an external thread 12 on its outer side, and the movable sleeve 6 has an internal thread 13 on its inner side. The internal thread 13 and the external thread 12 are matched. Through the cooperation between the fixed block 1, the mounting sleeve 2, the limiting block 3, the protruding block 4, the trapezoidal block 5, the movable sleeve 6, the moving ring 7, the mounting seat 8, the spring 10, the retaining ring 11, the external thread 12, the internal thread 13, and the mounting hole 14, the mounting seat 8 at the top of the needle 9 is aligned with the mounting sleeve 2. Then, the movable sleeve 6 is rotated, and the internal thread 13 and the external thread 12 of the movable sleeve 6 are matched. 2. Matching causes the movable sleeve 6 to move downwards, which in turn causes the moving ring 7 to move downwards. The retaining ring 11 on the inner side of the moving ring 7 is wider at the bottom and narrower at the top. The downward movement of the retaining ring 11 can cause the trapezoidal block 5 to move into the cavity, so that the protrusion 4 can be engaged with the inside of the mounting hole 14. Conversely, the retaining ring 11 releases the restriction on the trapezoidal block 5, and the needle 9 can be disassembled, achieving the effect of quick installation and disassembly, which is convenient and fast and improves work efficiency. At the same time, the cooperation of multiple protrusions 4 and mounting holes 14 can fix the mounting seat 8 of the needle 9 at multiple angles, improving the stability of the needle 9.

[0032] The mounting base 8 is provided with mounting holes 14 around its perimeter, and the mounting holes 14 match the protrusions 4.

[0033] The mounting base 8 has a set of positioning blocks 15 on its side, and the mounting sleeve 2 has a positioning groove 16 on its side. The positioning groove 16 and the positioning blocks 15 are matched. By cooperating with the positioning blocks 15 and the positioning groove 16, the positioning blocks 15 of the mounting base 8 can be aligned with the positioning groove 16 to achieve quick alignment and facilitate subsequent quick installation.

[0034] The movable sleeve 6 is provided with an auxiliary hole 17 on its periphery, which makes it convenient to use a tool to rotate the movable sleeve 6 through the auxiliary hole 17 when it is inconvenient to rotate the movable sleeve 6. The needle 9 is provided with a wire outlet hole 18 at its bottom.

[0035] The specific usage and function of this embodiment are as follows:

[0036] First, check the integrity of the device, then put it into actual use. When the needle 9 needs to be replaced, the positioning block 15 of the mounting base 8 can be quickly aligned with the positioning groove 16 by cooperating with the positioning block 15 and the positioning groove 16, which facilitates subsequent quick installation. Then, by cooperating with the fixing block 1, the mounting sleeve 2, the limiting block 3, the protruding block 4, the trapezoidal block 5, the movable sleeve 6, the moving ring 7, the mounting base 8, the spring 10, the retaining ring 11, the external thread 12, the internal thread 13, and the mounting hole 14, the mounting base 8 at the top of the needle 9 is aligned with the mounting sleeve 2, and then the movable sleeve is rotated. The internal thread 13 and external thread 12 of the movable sleeve 6 match, causing the movable sleeve 6 to move downwards, which in turn causes the moving ring 7 to move downwards. The retaining ring 11 on the inner side of the moving ring 7 is wider at the bottom and narrower at the top. When the retaining ring 11 moves downwards, it can cause the trapezoidal block 5 to move into the cavity, so that the protrusion 4 can be engaged inside the mounting hole 14. Conversely, when the retaining ring 11 releases the restriction on the trapezoidal block 5, the needle 9 can be disassembled, achieving the effect of quick installation and disassembly, which is convenient and fast, and improves work efficiency. At the same time, the cooperation of multiple protrusions 4 and mounting holes 14 can fix the mounting seat 8 of the needle 9 at multiple angles, improving the stability of the needle 9.
