Detailed Description
As shown in figure 1, the waterproof sealing quick-release cover mechanism consists of a cover 1, a sealing plate 2, a shell 3, a lock head 4, a connecting sheet 5 and a lower lock body 6. As shown in figure 1, realize safe and reliable through 4 groups of tapered ends 4 and lower locking body 6 and be connected between flap 1 and the casing 3, for satisfying the waterproof requirement between flap and the casing, install closing plate 2 between flap 1 and casing 3, and the through-hole diameter on the closing plate 2 is less than tapered end 4 upper portion cylinder diameter, and closing plate 2 uses the adhesive to paste on casing 3. As shown in fig. 4, in order to meet the installation requirements of different interlayer thicknesses, the connection between the lower lock body 6 and the housing 3 is switched through by the connecting plate 5, that is, the lower lock body 6 is riveted to the connecting plate 5 by 2 sets of rivets to form a combined body (as shown in fig. 3), and the combined body is riveted to the housing by 2 sets of rivets after passing through the square through groove 31 from the outside of the housing. The lock head 4 respectively passes through the through hole on the opening cover 1 and the through hole on the connecting sheet 5 to enter the lower lock body 6 according to the sequence of diagonal installation, and the fastening connection between the opening cover 1 and the shell 3 is realized after the lock head rotates 90 degrees; and similarly, the tapered ends 4 are respectively rotated by 90 degrees in opposite directions according to the sequence of diagonal disassembly, so that the tapered ends 4 are separated from the shell 3, the connecting sheet 5 and the opening cover 1, and the disassembly between the opening cover 1 and the shell 3 is realized. The specific implementation method of the waterproof sealing quick-release cover mechanism is as follows:
1. as shown in fig. 2, 4 groups of through grooves 31 are machined on the outer side of the shell in a machining mode;
2. as shown in fig. 3, 4 sets of lower locking bodies 6 are riveted to the connecting sheet 5 by 2 sets of rivets respectively to form a combined body;
3. as shown in fig. 4, the above-mentioned combination is passed through the square through groove 31 from the outside of the housing 3, and the connecting pieces 5 are lapped on both sides of the square through groove 31 and riveted to the housing 3 by rivets compared with the combination;
4. manufacturing the sealing plate 2 according to the size of the sunken upper opening frame of the shell 3, wherein the diameter of a through hole in the sealing plate 2 is smaller than that of a cylinder on the upper part of the lock head 4, so that a certain extrusion amount is ensured between the lock head 4 and the sealing plate 2; after the sealing plate 2 is manufactured as above, the sealing plate 2 is adhered to the housing 3 using an adhesive;
5. the opening cover 1 is tightly attached to the shell 3, the lock head 4 respectively penetrates through the through hole in the opening cover 1 and the through hole in the connecting piece 5 to enter the lower lock body 6 according to the sequence of diagonal installation, and the fastening connection between the opening cover 1 and the shell 3 is realized after the rotation of 90 degrees;
6. the tapered ends 4 are respectively rotated by 90 degrees in opposite directions according to the sequence of diagonal disassembly, so that the tapered ends 4 are separated from the lower locking body 6, the shell 3, the connecting sheet 5 and the opening cover 1, and the disassembly between the opening cover 1 and the shell 3 is realized.
