Therefore, the smart sewing machine needs to be powered effectively and stably, especially the power supply voltage needs to be stable without jumps.

[0003] Existing patent: CN202120192024.7 discloses an intelligent plug for an electric sewing machine, including a shell, a wiring harness is fixedly installed inside the shell, a wire groove located inside the shell is opened on the left side of the shell, a bottom plate is fixedly installed on the inner wall of the shell, a fixing clamp is movably installed on the front of the bottom plate, and a screw that penetrates the fixing clamp and extends to the front of the fixing clamp is fixedly installed on the front of the bottom plate. The intelligent plug for an electric sewing machine is arranged to be inserted into the fixing groove by setting a plug rod so that the flexible joint is fixedly connected to the shell through the joint, and the plug rod is connected by a spring so that the plug rod has good anti-bending performance.

[0030] See also Figures 1 to 8 , the present invention provides a technical solution:

[0031] Embodiment 1: A fiber-pollution-proof electric plug for an intelligent sewing machine comprises an output cable 1 and a socket box 2, wherein a connection post 3 connected to an input cable 6 is arranged in the socket box 2, a tray 4 is arranged in the middle section of the connection post 3, a sealing back plate 8 is arranged on one side of the socket box 2, a sealing sleeve 7 corresponding to the input cable 6 is arranged on the sealing back plate 8, the input cable 6 is plugged along the sealing sleeve 7 and extends to the connection post 3, the end of the input cable 6 is wound around the connection post 3 along the upper end surface of the tray 4, and a nut which is threadedly rotatably installed and pressed onto the input cable 6 is arranged on the upper end of the connection post 3.

[0032] By arranging the tray 4 and the nut, the input cable 6 is fixed on the power pole 3 to achieve a stable electrical connection.

[0033] An elastically pressed power connection piece 5 is arranged between adjacent pairs of power posts 3, and the lower end wire of the power post 3 is connected to one end of the power connection piece 5. A limit block 19 for limiting the parallel extension of the power connection piece 5 and a rotating shaft 31 for limiting the bending extension of the power connection piece 5 are arranged in the socket box 2. A parallel section is arranged at the inner side of the port where the power connection piece 5 extends to the sealing port 17, and a buffer pad 18 is arranged between the free ends of adjacent pairs of power connection pieces 5. A column 22 is arranged in the inner cavity of the socket box 2, and the parallel sections of a pair of adjacent power connection pieces 5 are fitted together. A top plate 42 is arranged on the other side of the parallel section, and a telescopic pressure rod 21 is slidably inserted between the top plate 42 and the column 22, and a first spring 20 is pressed between the end of the telescopic pressure rod 21 and the inner wall of the socket box 2.

[0034] The rotating shaft 31 is provided to realize smooth bending of the contact sheet 5, and the buffer block 18 is used to realize relative insulation separation of the free end of the contact sheet 5. Then, the telescopic pressure rod 21 and the first spring 20 cooperate to realize relative elastic pressing between a pair of contact sheets 5, thereby ensuring the stability of pressing of the power strip 10 inserted between the pair of contact sheets 5 and ensuring stable electrical connection.

[0035] The end of the output cable 1 is provided with an electrical terminal 26, and the electrical terminal 26 is provided with an electrical plug board 10 plugged into a pair of elastically pressed electrical terminals 5. One side of the socket box 2 is provided with a mounting groove 16 that matches the electrical terminal 26. The mounting groove 16 is connected to the electrical terminals 5 through a sealing port 17. The sealing port 17 has pneumatically telescopically driven sealing plates 23 symmetrically arranged on the upper and lower sides of the inner cavity. The middle inner cavity of the socket box 2 is set as a compression inner cavity 27. The inner cavity 27 is compressed. A piston rod 28 is slidably installed, a second spring 29 is sleeved on the piston rod 28, the compression inner cavity 27 is connected to the pneumatic telescopic part of the sealing plate 23, a sealing plug 9 is provided on the power terminal 26 and is sealed and plugged with the sealing port 17, and sealing grooves 25 are provided on the upper and lower end surfaces of the sealing plug 9 and are engaged with the sealing plate 23, a sliding ring 11 is slidably sleeved on the output cable 1, and a pressure column 15 is provided on the sliding ring 11, which extends to the front end of the power board 10 and is pressed on the piston rod 28.

[0036] Working principle: The sliding collar 11 installed slidably drives the pressure column 15 to extend to the front end of the power board 10, and then during the plugging process, the pressure column 15 is first pressed on the piston rod 28, so that the internal pressure of the compression cavity 27 increases, and the compressed airflow drives the sealing plate 23 to separate relatively, so that the sealing port 17 is opened, which is convenient for the plugging of the power board 10. After the plugging is completed, the sealing plug 9 is filled in the sealing port 17, and then the sliding collar 11 is driven to reset. Under the drive of the second spring 29, the piston 28 is reset, and the sealing plate 23 is relatively closed and pressed on the sealing plug 9. Due to the relative plugging of the sealing plate 23 and the sealing plug 9, the plugging position of the power board 10 is fixed, and the sealing of the sealing port 17 is further improved.

[0037] During the disassembly process, the sliding collar 11 is pushed and the piston rod 28 is squeezed to drive the sealing plate 23 to separate from the sealing plug 9. At this time, the power board 10 is pulled out to achieve disassembly.

[0038] Embodiment 2: On the basis of embodiment 1, a slide plate 43 is provided at one end of the telescopic pressure rod 21 close to the top plate 42, and a plurality of groups of connecting rods 32 distributed linearly are provided on the slide plate 43. A rotating ball assembly 35 is provided at the end of the connecting rod 32. A hemispherical rotating groove 34 cooperating with the rotating ball assembly 35 for rotating is provided on the top plate 42. A pressure plate 33 fixed with screws is provided on the top plate 42. The pressure plate 33 is pressed on the arc surface of the rotating ball assembly 35. The rotating ball assembly 35 includes an upper hemisphere 351 and a lower hemisphere 352. A rotating shaft 31 is vertically provided at the end of the connecting rod 32. An intermediate groove 44 is provided between the upper hemisphere 351 and the lower hemisphere 352. The upper hemisphere 351 and the lower hemisphere 352 are respectively rotatably installed at the two ends of the rotating shaft 31, and the pressure plate 33 is sleeved and installed along the connecting rod 32.

[0039] During the plugging process of the power strip 10, a pair of power strips 5 are squeezed to be relatively separated, and the power strips 5 squeeze the top plate 42. During this process, the top plate 42 and the power strips 5 are fixed, but the separation of the power strips 5 is a process of rotational deviation relative to the rotation shaft 31, which interferes with the telescopic pressure rod 21. The relative rotation generated by the adaptation of the rotating ball assembly ensures the relative elastic separation of the power strips 5.

[0040] Embodiment 3: On the basis of Embodiment 2, a pair of sealing plates 23 distributed up and down slide relative to each other and close, and a sealing strip 39 is provided at one opposite end of the sealing plate 23, the other side of the sealing plate 23 extends into the inner cavity of the socket box 2, and a lifting frame 37 is provided at the end of the sealing plate 23, the lifting frame 37 is connected to the pneumatic telescopic rod 36, the lower end of the pneumatic telescopic rod 36 is provided with an air nozzle 38, an air pipe 30 is provided in the compression inner cavity 27, the air pipe 30 is connected to the air nozzle 38, a slot 24 is provided on the socket box 2, the slot 24 is connected to the compression inner cavity 27, one end of the piston rod 28 is slidably installed in the compression inner cavity 27, the other end of the piston rod 28 is provided with an end cover and extends into the slot 24, the pressure column 15 is slidably inserted along the slot 24 and pressed on the end cover, and a second spring 29 is pressed between the end cover and the inner cavity of the slot 24.

[0041] By arranging the pneumatic telescopic rod 36, the air nozzle 38 and the air pipe 30, the compression cavity 27 is connected with the pneumatic telescopic rod 36, and the air pressure is mutually adjusted.

[0042] A fixed sleeve 12 is fixedly sleeved on the output cable 1, and a sliding sleeve 11 is located between the power terminal 26 and the fixed sleeve 12. A through hole 41 is provided on the power terminal 26. A pressure column 15 passes through the through hole 41 and extends to the front end of the power board 10. The length of the pressure column 15 is greater than the length of the power board 10. A plug hole 40 is provided on the outer wall of the power terminal 26. An elastic twist seat 13 is provided on the sliding sleeve 11. A rotating arm 14 is rotatably installed on the elastic twist seat 13, and an insert block that cooperates with the plug hole 40 is provided at the end of the rotating arm 14.

[0043] By setting a fixed collar 12 to limit the position of the sliding collar 11, the cooperation between the rotating arm 14 and the insertion hole 40 is utilized, so that before installation, the sliding collar 11 is pushed forward, and then the rotating arm 14 is plugged into the insertion hole 40 to achieve the purpose of fixing the position of the sliding collar 11. After the plugging is completed, the fixing is released by rotating the rotating arm 14. At this time, the sliding collar 11 slides toward the side of the fixed collar 12 under the reset drive of the piston rod 28.
