Description

Technical Field

[0001] The utility model relates to the technical field of sewing equipment, in particular to a sewing machine which is easy to assemble and disassemble. Background Art

[0002] A sewing machine is a machine that uses at least one thread to create one or more stitches on a material, interweaving or stitching one or more layers of material. Sewing machines are widely popular because they can sew a wide variety of materials, creating neat, beautiful, smooth, and secure stitches, as well as being fast and easy to use. China is the world's largest producer and consumer of sewing equipment, and sewing machines are one of the most popular types of sewing equipment.

[0003] Most common sewing machines on the market today have a two-piece housing design. During installation, the two pieces snap together and secure with multiple screws. While this connection method effectively secures the housing, it also presents a significant problem. Sewing machines are delicate devices that require the close coordination of various internal mechanisms to operate. Due to their complex internal structure, component failures are inevitable during operation. The multiple screws used to secure the housing make assembly and disassembly difficult, making it difficult to repair internal malfunctions. Summary of the Invention

[0004] In view of the defects of the prior art, the technical problem to be solved by the present invention is to provide a sewing machine that is easy to disassemble and assemble, and the shell of the sewing machine can be easily and quickly disassembled and assembled so as to facilitate maintenance when a fault occurs inside the sewing machine.

[0005] In order to solve the above technical problems, the present invention proposes a sewing machine that is easy to disassemble and assemble, which adopts the following technical solutions:

[0006] A sewing machine that is easy to disassemble and assemble comprises a shell and movement parts, wherein the movement parts are fixedly installed inside the shell, the shell comprises a first half shell, a second half shell and a covering shell, the first half shell and the second half shell are fixedly connected, the covering shell is fixedly installed at the rear of the first half shell and the second half shell, the covering shell is provided with a screw fixing hole, one screw fixing hole is provided, and the first half shell is provided with a mounting hole, the mounting hole corresponding to the screw fixing hole.

[0007] Compared to other sewing machines with only two half-shells that require the two half-shells to be fastened together and then fixed with multiple screws, this half-shell plus enclosure design reduces the number of screws required to fix the outer shell. After the two half-shells are fastened together, the enclosure is used to fix the half-shell connection, and then the screw fixing holes and mounting holes are tightened with screws. In this way, only one screw is required to lock and fix the entire outer shell, making assembly and disassembly very convenient. And although this design simplifies the disassembly and assembly process, because the half-shells and the enclosure are tightly fastened and screwed, the stability of the outer shell can still be ensured, ensuring the stability and durability of the sewing machine during operation and reducing the risk of failure due to structural looseness. The movement parts of the sewing machine use commercially available parts and installation methods, such as the 202 movement, to facilitate later product debugging.

[0008] Furthermore, the sidewalls of the first and second half shells are each provided with multiple slots, and the inner wall of the enclosure is provided with multiple protrusions, which engage with the slots. During assembly of the outer shell, the protrusions on the inner wall of the enclosure slide along the slots on the half shells until the two are locked. This design facilitates quick positioning and installation of the half shells and the enclosure during assembly.

[0009] Preferably, the first half shell is provided with a plurality of insertion holes, and the second half shell is provided with a plurality of insertion protrusions, with the insertion holes corresponding to the insertion protrusions. The presence of the insertion holes and the insertion protrusions facilitates quick positioning and installation of the sewing machine half shells during assembly, while also enhancing the stability of the structure.

[0010] Preferably, the second half shell is provided with an inspection port located on the rear side wall of the second half shell. The motor, as the core hub of the sewing machine, carries the task of operating the sewing machine and is prone to failure during operation. The reserved inspection port allows the motor to be repaired directly through the inspection port without disassembling the entire shell.

[0011] As an advantage, the device further comprises a breaking hole, which is fixedly arranged at the connection between the first half shell and the second half shell. The design of the breaking hole can better assist in the disassembly and assembly of the first half shell and the second half shell.

[0012] To sum up, during the installation process of this sewing machine that is easy to disassemble and assemble, the movement parts are first installed as a whole on the first half shell, and then the second half shell and the cover shell are installed in sequence, and then the entire shell is locked and fixed with a screw. In this way, quick disassembly and assembly can be achieved, making it convenient to repair when a fault occurs inside the sewing machine. BRIEF DESCRIPTION OF THE DRAWINGS
