Description

Technical Field

[0001] This application relates to the technical field of flat sewing machines, and in particular to a flat sewing machine with concealed wiring function. Background Technology

[0002] A flatbed sewing machine primarily uses a single sewing thread to create a stitch on the fabric, allowing one or more layers of fabric to interweave or sew together. It is generally divided into two types: one for thin materials and one for thick materials. Flatbed sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products made of leather, plastic, and paper. Thin materials are generally used for knitwear, underwear, shirts, and uniforms, while thick materials are generally used for various sportswear, denim, fashion apparel, coats, shoes, hats, leather goods, and bags.

[0003] Flatbed sewing machines are the most basic type of sewing equipment. They produce the simplest stitches, resulting in neat, beautiful, even, flat, and strong stitches. They are also fast and easy to operate. However, in existing flatbed sewing machines, after the thread is laid out, the thread is directly exposed above the machine head. During operation, the swaying thread may come into contact with components above the machine head, causing it to snag and affecting normal use.

[0004] Therefore, those skilled in the art have provided a flat sewing machine with concealed wiring function to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides a flat sewing machine with concealed wiring function.

[0006] The flat sewing machine with concealed wiring function provided in this application adopts the following technical solution:

[0007] A flat sewing machine with concealed wiring function includes a sewing table and a machine head installed above the sewing table. Both ends of the machine head are detachably mounted with C-shaped plates. Side support rods are fixedly installed at the two corners above the C-shaped plates. Fixing plates are fixedly connected to the right-angle ends of the two side support rods on the same side. A lower arched strip is installed between the ends of the two fixing plates. An upper arched strip is detachably mounted above the lower arched strip.

[0008] Preferably, insert plates are installed on both sides of the upper arched strip, and the insert plates on both sides are respectively inserted into the right-angle side of the fixing plate on the same side. Locking nuts are threaded to both ends of the fixing plate and the insert plates on the same side.

[0009] Preferably, a limiting nut is threadedly connected to one side of the C-shaped clamping plate, and an abutment block is fixedly connected to one end of the limiting nut.

[0010] Preferably, lead rods are installed at both ends of the external part of the machine head.

[0011] Preferably, support frames are installed on both sides of the lower surface of the sewing table.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] By using the limiting nuts at both ends, the abutment block is moved to fit tightly against the side of the machine head, thus limiting the position of the U-shaped clamping plate. This allows the lower arched strip to be installed above the machine head. In conjunction with inserting the side plates into the corresponding fixed plates, the upper arched strip fits against the lower arched strip, forming a cylindrical channel that conceals the exposed seams and effectively prevents the seams from snagging between the seams and components during use.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] refer to Figures 1-3 As shown, this application discloses a flat sewing machine with concealed wiring function, including a sewing table 2 and a machine head 6 installed above the sewing table 2. Both ends of the machine head 6 are detachably mounted with a U-shaped clamping plate 8. Side support rods 5 are fixedly installed at the two corners above the U-shaped clamping plate 8. Fixing plates 13 are fixedly connected to the right-angle ends of the two side support rods 5 on the same side. A lower arched strip 10 is installed between the ends of the two fixing plates 13. An upper arched strip 4 is detachably installed above the lower arched strip 10.

[0020] The lower arched strip 10 is installed above the machine head 6. Then, during the stitching process, the exposed upper seam is placed inside the lower arched strip 10, and the upper arched strip 4 is attached to the upper part of the lower arched strip 10 to form a cylindrical channel, which conceals the exposed seam and effectively prevents the seam from swinging and getting caught between the parts during use.

[0021] refer to Figures 1-3 As shown, insert plates 9 are installed on both sides of the upper arched strip 4, and the insert plates 9 on both sides are respectively inserted into the right-angle side of the fixing plate 13 on the same side. The fixing plate 13 and the insert plate 9 on the same side are threaded with locking nuts 11, which facilitates quick separation between the upper arched strip 4 and the lower arched strip 10, and makes it easy to place the sewing thread between the upper arched strip 4 and the lower arched strip 10.

[0022] refer to Figures 1-3 As shown, a limiting nut 7 is threadedly connected to one side of the C-shaped pallet 8. An abutment block 12 is fixedly connected to one end of the limiting nut 7. By rotating the limiting nut 7, the abutment block 12 is moved to fit tightly against the side of the machine head 6, thereby limiting the C-shaped pallet 8 and facilitating quick assembly and disassembly between the C-shaped pallet 8 and the machine head 6.

[0023] refer to Figure 1 and Figure 2 As shown, lead rods 3 are installed at both ends of the machine head 6, which can be inserted through a convenient wire spool for easy wiring.

[0024] refer to Figure 1 As shown, support frames 1 are installed on both sides of the lower surface of the sewing table 2 to provide support for the device.

[0025] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] The implementation principle of a flat sewing machine with concealed wiring function in this application embodiment is as follows:

[0028] In use, the two C-shaped clamps 8 are overlapped above the machine head 6. Then, the limiting nuts 7 at both ends are turned in sequence to move the abutment block 12 to fit tightly against the side of the machine head 6, thereby limiting the C-shaped clamps 8. This allows the lower arched strip 10 to be installed above the machine head 6. Then, when laying the stitches, the exposed upper stitches are placed inside the lower arched strip 10. Next, the two side inserts 9 are inserted into the corresponding side fixing plates 13, so that the upper arched strip 4 fits against the lower arched strip 10, forming a cylindrical channel that conceals the exposed stitches and effectively prevents the stitches from swinging and getting caught between the parts during use.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
