Technical Field
[0001] The utility model relates to the field of fabric processing equipment, and more specifically, to a sewing machine. Background Art
[0002] The main function of a sewing machine is to form one or more stitches on the sewing material by using one or more sewing threads, so as to interweave or sew one or more layers of sewing material. Existing sewing machines include electric sewing machines and manual sewing machines, both of which are more common in our daily life.
[0003] Among them, the manual sewing machine drives the sewing needle by hand or foot to sew. There are many parts inside the sewing machine. During the operation of the sewing machine, friction is likely to occur between the parts. Therefore, people need to regularly set lubricating oil between the parts to reduce the wear between the parts, thereby increasing the overall life of the sewing machine.
[0004] In the prior art, in order to facilitate the addition of lubricating oil, a through hole is opened on the existing shell, and people add lubricating oil to the parts in the sewing machine through the through hole. However, the closed area of the sewing machine shell is large, resulting in dim light inside the shell, and the lubricating oil generally needs to be added to the movable parts between the parts. The existing method generally increases the light inside the shell by using a flashlight, but holding the flashlight while adding lubricating oil makes the operation more cumbersome.
[0005] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content
[0006] In view of the deficiencies in the prior art, the utility model aims to provide a sewing machine.
[0007] The above technical purpose of the utility model is achieved through the following technical solutions: a sewing machine, including a desktop and a shell fixed on the top surface of the desktop, a mounting ring is integrally formed on the shell, a through hole connected to the interior of the shell is opened on the shell, a round cover for closing the through hole is provided on the mounting ring, the round cover is fixed to the mounting ring by bolts, the bolts are threadedly connected to the mounting ring, a light arranged near the through hole is fixedly connected to the inner wall of the shell, a key switch for controlling the light is installed on the inner circumferential wall of the mounting ring, and the round cover can control the light to be turned off by resisting the key switch.
[0008] The utility model is further configured as follows: the key switch is arranged close to the bolt.
[0009] The utility model is further configured as follows: the portion of the key switch exposed from the mounting ring is hemispherical.
[0010] The utility model is further configured as follows: a plurality of convex points are integrally formed on the inner wall of the shell.
[0011] The utility model is further configured as follows: a battery box is fixedly connected to the bottom surface of the desktop, and the light is provided with electric energy by batteries in the battery box.
[0012] The utility model is further configured as follows: a cover for closing the opening of the battery box is rotatably connected to the battery box.
[0013] The utility model is further configured as follows: the inner wall of the shell is coated with diffuse reflection paint.
[0014] In summary, the utility model has the following beneficial effects: the light can illuminate the space inside the shell, thereby making the space inside the shell brighter, making it easier for people to observe the positions of various parts, and the round cover contacts the button of the push switch, so that the light can change accordingly during the process of the round cover opening and closing the through hole, so that people will not forget to turn off the light, and the light is arranged close to the through hole, so that the light of the light will not directly shine into people's eyes, and the light will be emitted from the through hole after a certain reflection, thereby reducing the intensity of the light.

[0020] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] Sewing machines, such as Figure 1 and Figure 2As shown, it includes a desktop 1 and a shell 2 fixed on the top surface of the desktop 1, a mounting ring 3 is integrally formed on the shell 2, a through hole 4 communicating with the interior of the shell 2 is opened on the shell 2, the outer edge of the through hole 4 is flush with the inner edge of the mounting ring 3, a round cover 5 for closing the through hole 4 is provided on the mounting ring 3, the round cover 5 is fixed on the mounting ring 3 by bolts 6, and the diameter of the round cover 5 is larger than the outer diameter of the mounting ring 3, the bolts 6 are threadedly connected to the highest point on the mounting ring 3, and the position where the round cover 5 is passed by the bolts 6 is close to the outer edge of the round cover 5, a light 7 is fixedly connected to the inner wall of the shell 2, and a key switch 8 for controlling the light 7 is fixedly connected to the inner circumferential wall of the mounting ring 3, the keys on the key switch 8 can be exposed outside the mounting ring 3, when the keys of the key switch 8 are located in the mounting ring 3, the key switch 8 is disconnected, and when part of the keys of the key switch 8 are exposed outside the mounting ring 3, the key switch 8 is closed, and the round cover 5 can control the light 7 to be turned off by resisting the key switch 8, and people can rotate around the bolts 6 as the axis by loosening the bolts 6 on the mounting ring 3. The circular cover 5 is moved until all areas of the through hole 4 are completely exposed. At this time, the inner wall of the circular cover 5 does not conflict with the button of the key switch 8, so that one end of the button is exposed outside the mounting ring 3. At this time, the light 7 located on the inner wall of the shell 2 is turned on, and the light 7 illuminates the space in the shell 2, so that the space in the shell 2 is brighter, which is convenient for people to observe the positions of various parts. The light 7 is arranged close to the through hole 4, so that the light of the light 7 will not directly shine into people's eyes. The light will be reflected and then emitted from the through hole 4, thereby reducing the intensity of the light. After people add the lubricating oil, they turn the circular cover 5 to close the through hole 4. During the rotation of the circular cover 5, the outer peripheral wall of the circular cover 5 will conflict with the button on the key switch 8, so that the button enters the mounting ring 3 under the conflicting effect of the outer peripheral wall of the circular cover 5. At this time, the key switch 8 is disconnected and the light 7 is turned off. This arrangement makes the light in the shell 2 brighter during the process of adding lubricating oil, which is convenient for people to add lubricating oil, and people do not need to hold a flashlight, which is convenient for people to operate.
[0022] like Figure 2 As shown, the key switch 8 is arranged close to the bolt 6. This arrangement makes it necessary for the round cover 5 to rotate until most of the area of the through hole 4 is exposed before the key on the key switch 8 is exposed outside the mounting ring 3. The portion of the key switch 8 used to expose the mounting ring 3 is hemispherical. This arrangement makes it possible for the key to be subjected to a resistance component force moving toward the inside of the mounting ring 3 when the outer peripheral wall of the round cover 5 contacts the key, making it easier for the key to enter the mounting ring 3. A plurality of convex points are integrally formed on the inner wall of the shell 2. The arrangement of the convex points makes it easy for the light from the lamp 7 to be diffusely reflected on the convex points when it is irradiated on the inner wall of the shell 2, thereby increasing the number of light reflections and further weakening the light intensity. The inner wall of the shell 2 is coated with a diffuse reflection paint, and this arrangement further improves the softness of the light.
[0023] like Figure 3 and Figure 4 As shown, a battery box 9 is fixedly connected to the bottom surface of the desktop 1, and the light 7 is powered by batteries in the battery box 9. The light 7 has an independent power supply, so that the location of the sewing machine will not be restricted by the socket, and the battery box 9 is located on the bottom surface of the desktop 1, which is convenient for people to install the batteries in the battery box 9. The connecting wires between the battery box 9, the light 7 and the push switch 8 are all arranged close to the inner wall of the shell 2. A cover 10 for closing the opening of the battery box 9 is rotatably connected to the battery box 9. The setting of the cover 10 makes it difficult for dust and oil to enter the battery box 9, thereby ensuring the overall life of the battery.
[0024] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
