Description

Technical Field

[0001] The utility model relates to the field of flat-bed sewing machines, in particular to an anti-wrinkling quilt cover flat-bed sewing machine. Background Art

[0002] A flat-bed sewing machine is a machine that uses a sewing thread to form a seam on the sewing material, so that one or more layers of sewing materials are interwoven or sewn together. It is usually divided into two uses: thin materials and thick materials. The flat-bed sewing machine can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products such as leather, plastic, and paper.

[0003] In the prior art, in order to reduce the wrinkling of fabrics such as quilt covers during sewing, anti-wrinkle flat-bed sewing machines have appeared on the market. However, most of these flat-bed sewing machines do not have a good protective structure. Therefore, when the flat-bed sewing machine is idle at home, if the steel needle on the flat-bed sewing machine is accidentally touched, it is easy to cause certain injuries to personnel. Therefore, an anti-wrinkle quilt cover flat-bed sewing machine is needed. After searching, it was found that the technical solution provided by the utility model with application number CN201922426545.X also has the above-mentioned problems. Utility Model Content

[0025] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0026] Reference Figure 1-8 The utility model embodiment is a wrinkle-proof quilt cover flat sewing machine, which includes a flat sewing machine 1, a steel needle 2 is arranged on the flat sewing machine 1, a connecting block 3 is fixedly connected to the flat sewing machine 1, an anti-slipping block 4 is fixedly connected to the lower surface of the connecting block 3, a first protective box 5 and a second protective box 6 are movably connected to the outer surface of the anti-slipping block 4, the first protective box 5 and the second protective box 6 are both provided with anti-slipping grooves 7, the inner surfaces of the two anti-slipping grooves 7 are movably connected to the anti-slipping block 4, the first protective box 5 is in contact with the second protective box 6, and the number of the connecting blocks 3 is two and they are distributed on the left and right.

[0027] A fixed structure 14 includes a connecting rod 8, a flip block 9 and an insert block 10. The outer surface of the connecting rod 8 is rotatably connected to the flip block 9, the side surface of the flip block 9 is fixedly connected to the insert block 10, the outer surface of the insert block 10 is movably connected to the second protective box 6, a connecting groove 12 is provided on the first protective box 5, the inner surface of the connecting groove 12 is fixedly connected to the connecting rod 8, a slot 11 is provided on the second protective box 6, the inner surface of the slot 11 is movably connected to the insert block 10, a torsion spring 13 is fixedly sleeved on the outer surface of the connecting rod 8, one end of the torsion spring 13 is fixedly connected to the outer surface of the connecting rod 8, and the other end of the torsion spring 13 is fixedly connected to the inner surface of the flip block 9, the flip block 9 is in contact with the second protective box 6, and the number of fixed structures 14 is two and they are distributed on the left and right.

[0028] Working principle: Under the action of the first protection box 5 and the second protection box 6, the steel needle 2 on the flat sewing machine 1 can be protected to prevent the steel needle 2 from causing harm to the operator. By pulling the flip block 9 outward, the flip block 9 is flipped around the connecting rod 8, so that the flipped flip block 9 drives the insert block 10 to flip, and the flipped flip block 9 is disengaged from the slot 11 provided on the second protection box 6, so that the fixation between the first protection box 5 and the second protection box 6 can be released, and the first protection box 5 and the second protection box 6 can be separated to expose the steel needle 2, so that the flat sewing machine 1 can be used normally. When the flat sewing machine 1 is used, the anti-slip groove 7 on the first protection box 5 is inserted into the anti-slip block 4 on the connecting block 3, and then the flip block 9 is pulled to flip the flip block 9, so that the flipped flip block 9 pulls the connecting rod 8 on the connecting rod 8. The connected torsion spring 13 is flipped and stretched, so that the torsion spring 13 is in a flipped and stretched state, and the flipped flip block 9 will drive the plug block 10 to flip, so that the plug block 10 will not affect the connection between the first protective box 5 and the second protective box 6, and then the anti-slip groove 7 on the second protective box 6 is inserted against the anti-slip block 4, so that the first protective box 5 is in contact with the second protective box 6, so that the plug block 10 can correspond to the slot 11, and then the flipped flip block 9 is released, so that the torsion spring 13 is no longer restricted to flip and rebound, and then the rebounded torsion spring 13 drives the flip block 9 and the plug block 10 to flip, so that the flipped plug block 10 is inserted into the slot 11, thereby realizing the fixation between the first protective box 5 and the second protective box 6, completing the protection of the steel needle 2, and at the same time, under the action of the anti-slip block 4, the first protective box 5 and the second protective box 6 will not fall off the sewing machine 1.
