Description

Technical Field

[0001] The utility model relates to the technical field of textile sewing, and more specifically to a sewing machine protective cover for preventing fingers from being pricked. Background Art

[0002] A sewing machine is a mechanical or electric device used to sew cloth. It is widely used in the textile industry and households. It can efficiently complete various sewing tasks. When people are sewing, it is easy for the needle to prick their fingers, causing personal safety accidents. Therefore, the protective effect of the sewing machine is very important.

[0003] The Chinese patent authorization announcement number: CN204780219U provides a sewing machine protective cover for preventing finger pricks. The scheme includes a protective ring and a connecting rod fixing plate. The protective ring is installed on the connecting rod fixing plate through the left and right connecting rod plates. The connecting rod fixing plate and the machine head fixing plate are integrated and can be installed on the lower side of the sewing machine head. When protection is needed, the protective ring can be turned down to cover the periphery of the sewing needle. When the protective ring needs to be removed, the protective ring can be rotated 90 degrees upward around the connecting rod rotating shaft in the connecting rod fixing plate. The use of this sewing machine protective cover can avoid the shortcomings of slow response of the photoelectric protective device and finger pricks when the circuit fails, and can effectively prevent the danger of finger pricks for beginners. In addition, the material of the above utility model is high-strength transparent plastic, which will not block the operator's sight and can effectively prevent sewing workers from industrial accidents. However, the above device is reset by manually pressing the positioning steel column by the personnel. Since the positioning steel column is small, it is difficult for the operator to quickly position it, thereby increasing the difficulty of resetting the protective ring.

[0004] Therefore, in view of the above problems, a sewing machine protective cover for preventing fingers from being pricked is proposed. Utility Model Content

[0031] In this solution, by pulling the protective plate 14 downward, the connecting rod 12 and the telescopic rod 11 can drive the fixed block 7 to pull the first spring 6, so that the height of the protective plate 14 can be adjusted. The fixed block 7 drives the card ball 10 to slide in the fixed sleeve 15 through the second springs 9 at both ends of the inner wall, and after reaching the specified position, it engages with the card slot 13, so that the protective plate 14 can be fixed.

[0032] See also Figure 4 The pressing mechanism 2 includes an external block 201, which is fixedly connected to the outer wall of the fixed sleeve 15. A slot 13 is provided at the bottom of the outer wall of the fixed sleeve 15. Elastic columns 202 are slidably connected to the left and right ends of the outer wall of the external block 201, and the elastic columns 202 are engaged through the slot 13.

[0033] In this solution, an external block 201 is set on the outside of the fixed sleeve 15. By pressing the elastic column 202 on the outer wall of the external block 201, the elastic column 202 can be controlled to contact the blocking ball 10, thereby controlling the elastic column 202 to be squeezed inwardly through the second spring 9, thereby achieving rapid resetting of the protective plate 14.

[0034] See also Figure 2 and Figure 5 The outer wall of the protective plate 14 is provided with an empty groove 19; a connecting column 16 is fixedly connected to the left end of the front side of the outer wall of the sewing device 3, a rotating ball head 17 is fixedly connected to the outer wall of the connecting column 16, and a protective mirror 18 is rotatably connected to the outer wall of the rotating ball head 17; the protective mirror 18 is made of transparent material.

[0035] The present invention can increase the friction of the outer wall of the protective plate 14 by providing a hollow groove 19 on the outer wall of the protective plate 14, so that the fingers of the person can be placed on the outer wall of the protective plate 14; the front end of the outer wall of the sewing device 3 is rotatably connected to the protective glasses 18 through the connecting column 16 and the rotating ball head 17, so that the protective glasses 18 can be used to protect the eyes during sewing, thereby preventing textiles from splashing into the eyes and improving the safety of the device.

[0036] Working principle: When the operator starts to sew, the protective plate 14 can be moved downward through the connecting rod 12 and the telescopic rod 11 by pulling the protective plate 14. The purpose of setting the telescopic rod 11 is to fold the height to facilitate pulling the protective plate 14 up and down. The inner wall of the fixed block 7 is fixedly connected to the card ball 10 by the second spring 9. When the protective plate 14 moves downward, the card ball 10 slides on the inner wall of the fixed sleeve 15. When the protective plate 14 reaches the specified position, the card ball 10 is inserted into the card slot 13, thereby fixing the protective plate 14, and the external block 201 is fixedly connected to the outer side of the fixed sleeve 15 at a position corresponding to the card slot 13. By pressing the elastic column 202 on the outer wall of the external block 201, the card ball 10 can be squeezed inward by the deformation of the second spring 9, so that the protective plate 14 can be reset by the first spring 6, so that when not in use, the effect of quick reset is achieved, without affecting operations such as threading, thereby improving the convenience and practicality of the device.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
