Detailed Implementation

[0019] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0020] Examples, such as Figures 1-5 As shown, a sewing machine oil supply mechanism includes a mounting frame 1 and an oil storage box 4 disposed at the bottom of the mounting frame 1. A sliding plate 14 is slidably disposed on one side inside the oil storage box 4, and two top sliding plates 12 are slidably disposed inside the oil storage box 4. The sliding plate 14 is located between the two top sliding plates 12. The oil storage box 4 can store oil for use by the sewing machine. When oil is added into the oil storage box 4, the sliding plate 14 will float accordingly. When the sliding plate 14 floats to the top sliding plate 12 located above, the top sliding plate 12 will slide slightly inside the oil storage box 4, causing the LED on the upper side of the mounting frame 1 to flash. At this time, the operator can directly know the oil level inside the oil storage box 4 through the LED. Conversely, as the oil inside the oil storage box 4 is gradually used up, the sliding plate 14 will sink with the oil. At this time, the sliding plate 14 can contact another jacking slide plate 12. When the other jacking slide plate 12 is pressed and slides, the light bead on the upper side of the mounting frame 1 will stay on. In this way, the staff can add oil to the inside of the oil storage box 4 in a timely manner. It should be noted that the circuit for this process can be referenced. Figure 5 .

[0021] An oil supply pipe 9 is fixedly installed on one side of the oil storage box 4. The other end of the oil supply pipe 9 is connected to the oil storage box 6 through a flow rate adjustment mechanism. One end of the opening of the oil storage box 6 passes through the mounting frame 1 and extends to the upper side of the mounting frame 1. The operator can first fill the oil storage box 6 with oil so that a certain amount of oil can be stored inside the oil storage box 6. When the operator needs to add oil to the oil storage box 4, the flow rate adjustment mechanism can be turned so as not to affect the flow of oil. In this way, the oil can smoothly enter the oil storage box 4. The effect of this structure is that the operator can easily add oil to the oil storage box 4 when using the sewing machine, which increases its practicality.

[0022] Furthermore, two upper scale lines 10 and lower scale lines 11 are fixedly installed inside the oil storage box 4. Two actuating slide plates 12 are located between the two upper scale lines 10 and lower scale lines 11. The two actuating slide plates 12 are at the same height as the two upper scale lines 10 and lower scale lines 11 respectively. A fixed frame 15 is fixedly installed inside the oil storage box 4. The two ends of the sliding plate 14 are slidably connected to the inner wall of the fixed frame 15. The two actuating slide plates 12 are located inside the fixed frame 15. The two actuating slide plates 12 are at the same height as the upper scale lines 10 and lower scale lines 11 respectively. In this way, the staff can accurately judge the oil level through the light bulb. The fixed frame 15 provides sliding support for the sliding plate 14, so that the sliding plate 14 can slide against the inside of the oil storage box 4 to press the push plate 12.

[0023] Furthermore, the flow rate regulating mechanism includes a regulating pipe 7 located between the oil supply pipe 9 and the oil storage box 6, and a regulating knob 8 rotatably connected to the middle of the regulating pipe 7. The two ends of the regulating pipe 7 are fixedly connected to the oil supply pipe 9 and the oil storage box 6, respectively. Several first blocking blocks 16 are fixedly installed inside the regulating knob 8, and several second blocking blocks 17 that cooperate with the first blocking blocks 16 are fixedly installed in the lower half of the regulating pipe 7. The adjustment knob 8 has connecting grooves 18 at both the top and bottom ends, and the adjustment knob 8 is rotatably connected to the middle part of the adjustment tube 7 through the connecting grooves 18. The oil storage box 6 and the second blocking block 17 inside the adjusting knob 8 are the same size, and there is a certain gap between each first blocking block 16 and second blocking block 17. So, when the gap between the two overlaps, the oil can flow into the oil storage box 4 through the gap, thus filling the oil storage box 4 with oil. At the same time, the operator can manually adjust the size of the gap to control the flow rate of the oil. In order to eliminate the distance between the first blocking block 16 and the second blocking block 17, and at the same time enhance the sealing effect between the adjusting knob 8 and the adjusting tube 7, a connecting groove 18 is opened at both ends of the adjusting knob 8. This allows the connection between the adjusting tube 7 and the adjusting knob 8 to be submerged in the connecting groove 18, so that the adjusting knob 8 can be rotated and connected to the adjusting tube 7. This not only allows the first blocking block 16 and the second blocking block 17 to contact, but also greatly improves the sealing effect between the adjusting knob 8 and the adjusting tube 7.

[0024] The oil supply pipe 9, the regulating pipe 7, and the oil storage box 6 are all connected. The oil supply pipe 9 is connected to the inside of the oil storage box 4. The connection between the oil supply pipe 9, the regulating pipe 7, and the oil storage box 6 allows the oil inside the oil storage box 6 to flow into the oil storage box 4 through the regulating pipe 7 and the oil supply pipe 9, thereby enabling the oil to be added to the oil storage box 4.

[0025] Furthermore, a rotating cover 5 is threadedly connected to one end of the oil storage box 6 opening. The rotating cover 5 is used to open or close the opening of the oil storage box 6. The sewing machine body 2 is rotatably connected to the upper side of the mounting frame 1 via a flip plate 3. The rotating cover 5 can open or close the opening of the oil storage box 6, so that when the operator uses the sewing machine body 2, the oil inside the oil storage box 6 will not affect the operator's normal use. At the same time, the sewing machine body 2 is rotatably connected to the mounting frame 1 via the flip plate 3, making it convenient for the operator to flip up the sewing machine body 2 and then observe and clean the inside of the oil storage box 4.

[0026] In this embodiment, as Figures 1-5 As shown in the figure, the principle of the sewing machine oil supply mechanism provided in this embodiment is as follows: The oil storage box 4 can store oil for use by the sewing machine. When oil is added into the oil storage box 4, the sliding plate 14 will float. When the sliding plate 14 floats to the top sliding plate 12 located above, the top sliding plate 12 will slide slightly inside the oil storage box 4, causing the LED on the upper side of the mounting frame 1 to flash. At this time, the operator can directly know the oil level inside the oil storage box 4 through the LED. Conversely, as the oil inside the oil reservoir 4 is gradually used up, the sliding plate 14 will sink with the oil. At this time, the sliding plate 14 can contact another jacking slide plate 12. When the other jacking slide plate 12 is pressed and slides, the light bead on the upper side of the mounting frame 1 will stay lit. In this way, the staff can add oil to the inside of the oil reservoir 4 in a timely manner.
