Detailed Description

The present invention will now be described in detail with reference to the accompanying drawings.

Referring to fig. 1, the present invention provides a needle clamp 10 of a sewing machine with replaceable thread passing plate, wherein the needle clamp 10 is provided with a plurality of sewing needles 20 mounted thereon and driven by a needle clamp driving rod 21 to make a reciprocating motion. Referring to fig. 1 to 7, the needle bar 10 of the sewing machine includes a needle bar body 11 assembled with the needle bar driving rod 21, a thread passing plate 13 and a pressing plate 14, the needle bar body 11 having a first groove 111 disposed at one end and a second groove 112 disposed at a side of the needle bar body 11 not facing at least one yarn and communicating with the first groove 111. Further, the first groove 111 is provided on the side of the needle mount body 11 not connected to the needle mount driving lever 21, i.e., the side facing a sewing machine presser foot 22. In one embodiment, the first slot 111 penetrates two opposite sides of the sewing needle 10, and one side of the first slot 111 is the side of the sewing needle 10 facing the yarn (not shown), which defines the front side of the sewing needle 10, and the other side of the first slot 111 is the back side of the sewing needle 10. On the other hand, the second slot 112 of the present invention is disposed on the back of the sewing machine needle 10, and the surface of the second slot 112 is perpendicular to the surface of the first slot 111. The second slot 112 includes a first segment 113 connected to the first slot 111 and a second segment 114 connected to the first segment 113 and having a width greater than that of the first segment 113.

In summary, the wire passing plate 13 has an assembling section 131 disposed in the first groove 111, a limiting section 132 connected to the assembling section 131 and disposed in the second groove 112, and a wire passing section 133 extending from a side of the assembling section 131 not connected to the limiting section 132. The position-limiting section 132 includes a neck 134 corresponding to the first section 113 of the second groove 112, and a head 135 disposed in the second section 114 of the second groove 112 and limited by the first section 113 of the second groove 112. In addition, the thread passing section 133 is formed with a plurality of thread passing holes 136 for the yarn to pass through. In one embodiment, the needle mount body 11 is made of a first material, and the wire-passing plate 13 is made of a second material different from the first material. For example, the first material is metal, and the second material is ceramic. On the other hand, the pressing plate 14 is installed on the side of the needle clamp body 11 where the second slot 112 is located, and the pressing plate 14 at least presses the limiting section 132 of the wire passing plate 13. In one embodiment, the second slot 112 is tapered, and the head 135 is disposed at the widest point within the second slot 112.

Bearing, this sewing machine needle clamp 10 assembles originally, assembles this wire passing plate 13 and this needle clamp body 11 earlier, should cross this assembly section 131 card of wire passing plate 13 and put into this first groove 111, should cross this spacing section 132 of wire passing plate 13 then put into this second groove 112, and this head 135 of this spacing section 132 receives the restriction of this second groove 112 structure, makes this wire passing plate 13 obtain the location of first stage. Thereafter, the pressing plate 14 is disposed corresponding to the side of the sewing machine needle 10 not facing the yarn, and at least the position-limiting section 132 of the thread-passing plate 13 is pressed, so that the thread-passing plate 13 is positioned in the second stage. Therefore, the threading plate 13, which is not the original structure of the needle clamp body 11, can be limited by the structure of the second groove 112 and the pressing plate 14 during sewing, and will not fall off during sewing. In addition, the present invention makes the wire-passing board 13 easily replaceable by this design.

Referring back to fig. 3 and 5, in one embodiment, the platen 14 is disposed within the second slot 112, and the second slot 112 further has a third segment 115 extending from the second segment 114 and providing the platen 14 therein. It should be understood that, in the present embodiment, the pressing plate 14 is not only disposed in the third section 115 of the second groove 112, but also disposed in the second section 114 of the second groove 112 to press the head 135 in the second section 114. Furthermore, the needle clamp body 11 may further have a mounting hole 116 disposed in the third section 115 of the second slot 112 and providing a pressing plate assembly 15, and the pressing plate assembly 15 may be a screw. In addition, in an embodiment, the pressing plate 14 includes an installation portion 141 located in the second groove 112 and a pressing portion 142 connected to the installation portion 141 and pressing the limiting section 132 of the wire passing plate 13, and the pressing portion 142 and the installation portion 141 are located at different horizontal planes, as illustrated in fig. 3 and 7.

Referring to fig. 7, in an embodiment, the needle mount body 11 has a plurality of sewing needle mounting holes 117 formed in the first groove 111, the thread guide plate 13 has at least one needle passing hole 137 corresponding to the sewing needle mounting holes 117, the sewing needle mounting holes 117 have a first extension thread 118, and each thread passing hole 137 has a second extension thread 138 capable of crossing the first extension thread 118.

The above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made in the claims of the present invention should be covered by this patent.
