[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0032] Referring to Figure 2 、 Figure 4 and Figure 5 , an embodiment provided by the present invention: a needle plate includes a cover body 1 and a needle plate body 2. The cover body 1 serves as the upper cover of the needle plate, and its design ensures the sealing and convenient operation of the needle plate. A clamping rod 3 is fixedly connected inside the cover body 1. An installation groove 4 is formed inside the needle plate body 2. The outer wall of the clamping rod 3 is in contact with the inner wall of the installation groove 4. The installation groove 4 is used to accommodate the clamping rod 3. The design of the installation groove 4 ensures that the clamping rod 3 can slide smoothly and limits it when necessary. A partition 5 is fixedly connected to the rear inner wall of the installation groove 4. A fitting port 6 is formed at the left end inside the partition 5. An I-shaped plate 7 is slidably connected to the inner wall of the fitting port 6. The fitting port 6 is used to cooperate with the I-shaped plate 7 to enable it to slide smoothly. The left end of the clamping rod 3 is in contact with the right end of the I-shaped plate 7.
[0033] A sliding rod 8 is fixedly connected to the left end of the bottom of the I-shaped plate 7. A spring 9 is sleeved outside the sliding rod 8. The right end of the spring 9 is fixedly connected to the left end of the bottom of the I-shaped plate 7. The spring 9 provides a supporting and limiting function between the I-shaped plate 7 and the sliding rod 8 through its elastic action. A limiting plate 10 is fixedly connected to the left end of the sliding rod 8. A chamber 11 is formed inside the needle disc body 2. A fixed block 12 is fixedly connected to the inner wall of the chamber 11. The outside of the sliding rod 8 is slidably connected inside the fixed block 12. The limiting plate 10 is used to prevent the sliding rod 8 from sliding out of the chamber 11. The fixed block 12 provides a stable sliding path for the sliding rod 8. The left end of the spring 9 is fixedly connected to the right end of the fixed block 12. The right end of the limiting plate 10 is in contact with the left end of the fixed block 12. An opening 13 is formed at the top of the installation groove 4 for positioning to enable the engaging rod 3 to enter the installation groove 4. A backing plate 17 is fixedly connected to the top end of the middle part of the needle disc body 2 for increasing the sealing performance between the middle part of the needle disc body 2 and the cover body 1. The bottom inner wall of the cover body 1 is in contact with the top end of the backing plate 17. A plurality of placement grooves 18 are formed inside the needle disc body 2 for placing the needles.
[0034] Refer to Figure 1 , Figure 2 and Figure 3 , a sealing assembly for sealing the needle disc is rotatably connected inside the cover body 1. The sealing assembly includes a rotating rod 14. The outside of the rotating rod 14 is rotatably connected inside the cover body 1. The bottom of the rotating rod 14 is in threaded connection with the inside of the needle disc body 2. A knob 15 is fixedly connected to the top end of the rotating rod 14. The bottom end of the knob 15 is in contact with the top end of the cover body 1. Rotating the knob 15 causes the rotating rod 14 to rotate, thereby driving the needle disc body 2 to rise or fall to achieve the sealing of the needle disc. The threaded connection of the rotating rod and the operation of the knob 15 ensure the precise adjustment of the needle disc and a good sealing effect. A sealing ring 16 is fixedly connected to the bottom inner wall of the cover body 1. The bottom end of the sealing ring 16 is in contact with the top end of the needle disc body 2. The needle disc body 2 moves upward through the threaded connection so that the sealing ring 16 fits tightly with the needle disc body 2. The cooperation of the backing plate 17 ensures the sealing effect between the cover body 1 and the needle disc body 2, thereby preventing the entry of dust and moisture and prolonging the service life of the needles.
[0035] Working principle: by aligning the locking rod 3 in the cover body 1 with the opening 13 on the needle disk body 2 and pressing it downward until the locking rod 3 contacts the partition plate 5, and then rotating the cover body 1 to drive the locking rod 3 to slide in the installation groove 4, at this time, the I-shaped plate 7 is squeezed and moves to the left, and the spring 9 is compressed by the pressure until the locking rod 3 loses contact with the partition plate 5, and then the cover body 1 is pressed downward again to drive the locking rod 3 to move downward, and then the cover body 1 is rotated counterclockwise to drive the locking rod 3 to move to the right. At this time, the compressed spring 9 generates pressure to drive the I-shaped plate 7 to move to the right and resist the locking rod 3, thereby completing the limit of the locking rod 3, thereby quickly realizing the closing of the needle disk, and similarly, the needle disk can be opened by rotating the cover body 1 in the reverse order of the above steps;
[0036] When the needle dial is closed, the rotating rod 14 is driven to rotate by turning the knob 15. Since the bottom of the rotating rod 14 is threadedly connected to the inside of the needle dial body 2, the rotation of the rotating rod 14 drives the needle dial body 2 to move upward, thereby achieving a tight fit between the needle dial body 2 and the sealing ring 16. Combined with the fit between the top of the pad 17 and the inner wall of the cover body 1, the sealing of the needle dial is enhanced, dust and moisture are prevented from entering the interior of the needle dial, and the needle tip is protected from contamination, thereby extending its service life and maintaining its performance.
[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
