[0019] like Figures 1 to 7As shown, this utility model discloses a waterproof and dustproof structure for a laptop's connector, which is assembled in the functional port 2 of the lower casing 1 of the laptop. The functional port 2 integrates multiple connection ports 3. The waterproof and dustproof structure includes a cover 4, which is snapped into the functional port 2. The bottom of the cover 4 is bent and connected to an integrally formed connecting plate 5. The connecting plate 5 is fixedly connected to the lower casing 1 of the laptop. The outer side of the cover 4 is provided with a mounting groove 6, and a sliding pin assembly is slidably assembled in the mounting groove 6. The sliding pin assembly includes a sliding plate 7 and a locking tongue 8 mounted on the sliding plate 7. The sliding plate 7 has an outwardly bent handle 9, which allows the sliding plate 7 to be easily pulled up or down. The lower casing 1 of the laptop located at the functional port 2 is provided with a corresponding matching slot 10 for the locking tongue 8. The cover 4, the connecting plate 5, and the sliding pin assembly are all made of elastic material.
[0020] The lower casing 1 of the laptop, located at the function port 2, has a connecting groove 11. After the connecting plate 5 is placed on the connecting groove 11, it is fixed to the lower casing 1 of the laptop by screws 12.
[0021] The mounting slot 6 has a receiving slot 13, the locking tongue 8 is placed in the receiving slot 13, and the mounting height of the locking tongue 8 is higher than the plane height of the sliding plate 7.
[0022] The mounting groove 6 is provided with a locking groove, which is divided into an upper locking groove 14 and a lower locking groove 15. The upper locking groove 14 and the lower locking groove 15 are set vertically. The sliding plate 7 located below the locking tongue 8 is provided with a sliding pin buckle 16 that matches the locking groove. There are two upper locking grooves 14 and two lower locking grooves 15, which are located at both ends of the mounting groove 6 respectively. There are two sliding pin buckles 16. The mounting groove 6 located below the lower locking groove 15 is provided with a protrusion 17. The sliding plate 7 is provided with a protrusion 18 corresponding to the protrusion 17, so that when the locking tongue 8 is engaged in the locking groove 10, the protrusion 17 is located above the protrusion 18.
[0023] There is a height gap between the bottom surface of the slide plate 7 and the bottom surface of the mounting groove 6. The height gap is the height distance between the upper locking groove 14 and the lower locking groove 15. When the slide plate 7 is slid upward, the locking tongue 8 can be inserted into the locking groove 10 and the sliding pin buckle 16 can be inserted into the upper locking groove 14. When the slide plate 7 is slid downward, the locking tongue 8 is disengaged from the locking groove 10 and the sliding pin buckle 16 is inserted into the lower locking groove 15. The bottom of the slide plate 7 is provided with an extension 19, which extends downward to the mounting groove 6.
[0024] The closed state of this utility model refers to the state in which the cover 4 is assembled in the functional port 2 and needs to achieve waterproof and dustproof; the open state refers to the state in which the cover 4 is removed from the functional port 2 and the functional port 2 can be used normally.
[0025] Specifically, since the cover 4, connecting plate 5, and sliding pin assembly are all made of elastic materials—that is, the locking tongue 8, sliding pin buckle 16, protrusion 17, and protrusion 18 are also made of elastic materials—and the connecting plate 5, which is integrally formed with the cover 4, is fixed to the lower casing 1 of the laptop, the cover 4 can be rotated. When waterproofing and dustproofing are required (i.e., to achieve a closed state), the cover 4 is rotated towards the functional opening 2 to insert the cover 4 into the functional opening 2. Then, the handle 9 is pulled upwards to slide the slide plate 7 upwards in the mounting groove 6, so that the locking tongue 8 can engage with the slot 10, thus connecting the cover 4 and the laptop. The locking mechanism between the lower housing 1 provides waterproof and dustproof performance. At this time, the sliding pin 16 is engaged in the upper slot 14, and the protrusion 17 is located above the protrusion 18. When the function port 2 needs to be used normally (that is, to achieve the open state), press down the handle 9, and the slide plate 7 slides down in the mounting groove 6. The sliding pin 16 slides into the lower slot 15, the protrusion 17 is located below the protrusion 18, and the locking tongue 8 is located in the receiving groove 13. At this time, the locking tongue 8 disengages from the slot 10, so the cover 4 can be unlocked and removed from the function port 2, thus enabling the normal use of the function port 2.
