Description

Technical Field

[0001] The utility model relates to the technical field of watch case oil filling, in particular to a watch case oil filling structure. Background Art

[0002] Watch case oiling means using PVC material to produce the watch case. The inside of the watch case is equipped with a waterproof watch movement, and non-toxic oils of various colors are injected into the inside of the case to improve the comfort and aesthetics of the watch.

[0003] For example, the Chinese utility model patent with publication number CN219039581U proposes a stainless steel watch case oil filling device. When in use, the device needs to squeeze and fix the watch case through a limiting structure, and then the oil outlet lifting column moves downward so that the oil filling plate and the watch case are against each other, and the oil outlet nozzle at the bottom of the oil filling plate completes the oil filling process. This device is also suitable for oiling PVC plastic watch cases, but after the oil filling is completed, the watch case cannot be sealed immediately. The watch case needs to be removed after the oil is filled and sealed through an additional process to prevent oil leakage, which makes the watch production process complicated and the remaining efficiency low.

[0004] To this end, the utility model provides a watch case oil inlet structure. Utility Model Content

[0021] In this embodiment, a magnet 9 is fixedly provided at the bottom of the transverse plate 6, and the magnet 9 is arranged above the electromagnet 7. A sliding rod 8 is fixedly provided at the bottom of one end of the transverse plate 6, and the bottom end of the sliding rod 8 is slidably installed inside the second inner cavity 11. Through the mutual repulsion of the electromagnet 7 and the magnet 9, it is convenient to adjust the transverse plate 6 and the oil inlet pipe 2 upward. The sliding rod 8 can limit the transverse plate 6 and the oil inlet pipe 2 to prevent the oil inlet pipe 2 from rotating, which is convenient for the subsequent discharge of the PVC solution.

[0022] In this embodiment, a fixing plate is fixedly provided at the upper end of the oil inlet pipe 2, and the fixing plate is arranged inside the first inner cavity 3. A spring 10 is fixedly installed between the top of the fixing plate and the top wall of the first inner cavity 3. The spring 10 is sleeved on the oil inlet pipe 2. When the oil inlet pipe 2 moves upward, it can drive the fixing plate to squeeze the spring 10, so as to facilitate the resetting of the oil inlet pipe 2 after the pouring is completed.

[0023] In this embodiment, a resistance wire heater 5 is fixedly installed inside the second inner cavity 11. The resistance wire heater 5 is wound into a spiral shape. By installing the resistance wire heater 5 inside the second inner cavity 11, the PVC can be heated, thereby ensuring that the PVC can flow downward inside the first inner cavity 3, which is convenient for the subsequent sealing of the watch case.

[0024] In this embodiment, a watch case is provided at the bottom of the oil inlet pipe 2, and an addition port is opened on one side of the top of the watch case, and a groove is provided at the top of the addition port. A tip is provided at the bottom end of the oil inlet pipe 2, and the tip is arranged inside the addition port. A watch movement is fixedly provided inside the watch case, and the tip is arranged at the bottom of the tube body 1. A sealing rubber ring 12 is fixedly provided at the bottom end of the oil inlet pipe 2, and the sealing rubber ring 12 contacts the inner wall of the first inner cavity 3. A rubber ring is fixedly provided inside the bottom end of the first inner cavity 3, and the rubber ring is arranged on the outside of the tip. Oil is conveniently added to the interior of the watch case through the addition port, and the first inner cavity 3 and the oil inlet pipe 2 can be sealed by the sealing rubber ring 12, thereby preventing PVC from flowing out during the oil addition process.

[0025] When using the watch case oil filling structure, the tube body 1 is fixedly connected to the lifting mechanism, and a clamping or limiting mechanism is provided under the tube body 1. The watch case is clamped and fixed by the clamping or limiting mechanism. At this time, the tip of the oil inlet pipe 2 is aligned with the groove and the adding port on the watch case. The oil inlet pipe 2 is fixedly connected to the oil supply equipment through a pipeline, and the feeding pipe 4 is connected to the feeding equipment through another pipeline. The tube body 1 is driven down by the lifting mechanism, and the tube body 1 drives the oil inlet pipe 2 to descend and inserts the tip into the inside of the adding port. Non-toxic oils of various colors are added to the inside of the watch case through the oil inlet pipe 2 and the adding port. After the oil filling is completed, the electromagnet 7 is energized, and the top of the electromagnet 7 generates a magnetic field with the same polarity as the bottom of the magnet 9. Through the mutual repulsion between the electromagnet 7 and the magnet 9, the horizontal plate 6 can be adjusted upward , the oil inlet pipe 2 of the horizontal plate 6 rises, and the oil inlet pipe 2 is compressed by the fixed plate spring 10, and its bottom end is separated from the inner wall of the first inner cavity 3, so that the PVC solution flows downward through the gap between the oil inlet pipe 2 and the first inner cavity 3, thereby entering the inside of the groove and the addition port, and the PVC solution is cooled and solidified, thereby closing the addition port, and by installing a resistance wire heater 5 inside the second inner cavity 11, the PVC melt inside the first inner cavity 3 can be heated and kept warm, thereby ensuring that the PVC is in a liquid state, and facilitating the downward discharge of the PVC, thereby simplifying the watch production process and improving the watch production efficiency. Under the elastic force of the fixed plate and the spring 10, the oil inlet pipe 2 closes the bottom end of the first inner cavity 3 through the sealing rubber ring 12, which can prevent the PVC solution from flowing downward during the oil inlet process.
