DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 8 As shown, the present invention provides an aluminum electrode connection sealing device for an aluminum-air battery, comprising a sealing shell 1, a battery body 2 is arranged inside the sealing shell 1, an electrode body 3 is fixedly installed on the top of the battery body 2, a sealing plate 4 is sleeved on the surface of the top of the sealing shell 1, and a wire outlet hole 14 is opened on the top of the sealing plate 4; A fixing mechanism is arranged inside the sealing plate 4, and the fixing mechanism includes a slide rail 5, which is fixedly connected to the inside of the sealing plate 4. A slider 6 is slidably sleeved on the surface of the slide rail 5, and a connecting plate 7 is fixedly installed on the bottom end of the slider 6. Plug holes 12 are provided on both sides of the inside of the sealing shell 1, and a plug block 8 located inside the plug hole 12 is fixedly installed on one side of the connecting plate 7. A threaded rod 9 located at the top end of the slide rail 5 is rotatably connected inside the sealing plate 4, and a threaded block 10 is threadedly sleeved on the surface of the threaded rod 9. The threaded block 10 is hinged to the slider 6 through a hinged rod 11, and a rotating disk 13 is fixedly installed on the top end of the threaded rod 9.

[0020] According to the above scheme, the operator installs the battery body 2 inside the sealed shell 1, and then installs the required conductive wire on the surface of the electrode body 3, and passes one end of the conductive wire through the outlet hole 14, and then sets the sealing plate 4 on the surface of the top of the sealed shell 1, and then connects the conductive wire to the external device, so as to charge the device; After the sealing plate 4 is sleeved on the surface of the sealing shell 1, the rotating disk 13 can be rotated, and the rotating disk 13 will drive the threaded rod 9 to rotate. Since the threaded rod 9 is threadedly connected with the threaded block 10, when the threaded rod 9 rotates, the threaded block 10 will move on the surface of the threaded rod 9. Since the threaded block 10 is hinged with the slider 6 through the hinge rod 11, when the threaded block 10 moves, it will drive the hinge rod 11 to rotate. The rotating hinge rod 11 will push the slider 6 to move toward each other on the surface of the slide rail 5. Then the slider 6 will drive the connecting plate 7 and the plug block 8 to move, and then the plug block 8 will enter the inside of the socket 12, so that the sealing plate 4 is fixed to the top of the sealing shell 1 through the socket 12, and then the battery body 2 and the electrode body 3 are sealed. Finally, the rotating disk 13 is rotated to make the plug block 8 enter the inside of the socket 12, and then the battery body 2 and the electrode body 3 can be sealed without using fixing bolts, effectively preventing dust, moisture and other impurities from entering the battery, ensuring the normal operation of the battery and extending the service life.

[0021] like Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, it also includes: a blocking mechanism, which is arranged at the top of the threaded block 10, the blocking mechanism includes a rack 16, the rack 16 is fixedly connected to the top of the threaded block 10, the inside of the sealing plate 4 is fixedly installed with an air bag 15 located on the surface of the outlet hole 14, one side of the surface of the air bag 15 is fixedly installed with an intake pipe 20, the inside of the sealing plate 4 is rotatably connected with a gear 17 meshing with the rack 16, one side of the gear 17 is fixedly installed with a screw rod 18 located inside the intake pipe 20, and the surface of the screw rod 18 is threadedly connected with a blocking block 19 located inside the intake pipe 20.

[0022] The above scheme is adopted: through the design of the blocking mechanism, when the threaded block 10 moves, the rack 16 will be linked to move, because the rack 16 is meshed with the gear 17, and then the moving rack 16 will drive the gear 17 to rotate, and the gear 17 will drive the screw 18 to rotate. Since the screw 18 is threadedly connected with the blocking block 19, when the screw 18 rotates, the blocking block 19 will move on the surface of the screw 18, and then the blocking block 19 will move toward the inside of the intake pipe 20, thereby squeezing the inside thereof. The air is then squeezed into the airbag 15, and after the air enters the airbag 15, the airbag 15 expands, and then the surface of the airbag 15 contacts the conductive wire inside the outlet hole 14, and then the airbag 15 can block the outlet hole 14, and finally the airbag 15 is expanded by the threaded block 10 linking the rack 16, and then the outlet hole 14 can be blocked, preventing dust from entering the inside of the sealing shell 1 along the outlet hole 14, thereby improving the sealing performance of the sealing shell 1.

[0023] like Figure 2 and Figure 6 As shown, a plug plate 21 is arranged inside the sealing plate 4, a sealing groove 23 is opened at the top of the sealing shell 1, a sealing ring 22 located inside the sealing groove 23 is fixedly installed at the bottom of the plug plate 21, and a limiting hole 24 is opened on the surface of the plug plate 21.

[0024] By adopting the above scheme: through the design of the plug plate 21, the sealing ring 22 and the sealing groove 23, when the sealing plate 4 is sleeved on the surface of the top end of the sealing shell 1, the sealing ring 22 will enter the interior of the sealing groove 23. Since the surface of the sealing ring 22 fits with the inner wall of the sealing groove 23, the sealing effect of the sealing shell 1 is increased.

[0025] like Figure 3 , Figure 6 and Figure 7 As shown, it also includes: a limiting mechanism, which is arranged inside the sealing plate 4, the limiting mechanism includes a square shell 25, the square shell 25 is fixedly connected to the inside of the sealing plate 4, both ends of the square shell 25 are rotatably connected with gear 26, the inside of the square shell 25 and the gear 2 26 are slidably connected with screw rod 27, and gear 26 is threadedly connected with screw rod 27, the number of screw rod 27 is two, and the two screw rods 27 facing each other are fixedly installed with limiting blocks 1 28 located inside the limiting hole 24, the inside of the sealing plate 4 is rotatably connected with a rotating rod 29, and the surface of the rotating rod 29 is fixedly sleeved with a gear 3 30 meshing with gear 26.

[0026] The above scheme is adopted: through the design of the limiting mechanism, when the sealing ring 22 is used for a long time and needs to be replaced, the rotating rod 29 can be rotated, and then the rotating rod 29 will drive the gear three 30 to rotate. Since the gear three 30 is meshed with the gear two 26, the rotating gear three 30 will drive the gear two 26 to rotate. Since the gear two 26 is threadedly connected with the screw rod two 27, when the gear two 26 rotates, the screw rod two 27 will slide inside the gear two 26 and the screw rod two 27, and then the screw rod two 27 will pull the limiting block one 28 away from the inside of the limiting hole 24. After the limiting block one 28 is away from the inside of the limiting hole 24, the fixing of the plug plate 21 and the sealing ring 22 will be cancelled, and then the operator can replace the plug plate 21 and the sealing ring 22; Then, the unused plug plate 21 and sealing ring 22 can be inserted into the interior of the sealing plate 4, and then the rotating rod 29 and gear three 30 can be rotated in the opposite direction, so that the gear three 30 drives the gear two 26 to rotate in the opposite direction, and then the screw rod two 27 will drive the limit block one 28 to move into the interior of the limit hole 24. When the limit block one 28 enters the interior of the limit hole 24, the plug plate 21 and the sealing ring 22 can be limited, and then the sealing shell 1 can continue to be sealed. Finally, the limit block one 28 is moved by rotating the rotating rod 29, so that the operator can replace and install the plug plate 21 and the sealing ring 22 conveniently, thereby increasing the convenience of the device.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, a mounting plate 31 is fixedly installed inside the sealing plate 4, a spring 32 is fixedly installed on one side of the mounting plate 31, and one end of the spring 32 is fixedly connected to the plug block 8, and a limiting ring 33 located on the surface of the threaded rod 9 is rotatably connected inside the sealing plate 4, and the limiting ring 33 is fixedly connected to the threaded rod 9, and the surface of the limiting ring 33 fits against the inner wall of the sealing plate 4.

[0028] The above scheme is adopted: through the design of the mounting plate 31 and the spring 32, since one end of the spring 32 is fixedly connected to the plug block 8, when the plug block 8 moves, the spring 32 will be stretched, and then when the plug block 8 is away from the inside of the socket 12, through the resilience of the spring 32, the spring 32 will pull the plug block 8 to reset, thereby reducing the load on the threaded rod 9 and increasing the service life of the fixing mechanism. Through the design of the limit ring 33, when the threaded rod 9 rotates, the limit ring 33 will rotate accordingly. Since the surface of the limit ring 33 fits with the inner wall of the sealing plate 4, the threaded rod 9 can be limited and supported during the rotation of the limit ring 33, thereby ensuring the stable rotation of the threaded rod 9.

[0029] like Figure 2 and Figure 7 As shown, a limiting groove 34 is provided inside the square shell 25, and a limiting block 35 located inside the limiting groove 34 is fixedly installed at the other end of the second screw rod 27. The surface of the rotating disk 13 is provided with a protrusion, and the protrusion is of a rough design.

[0030] The above scheme is adopted: through the design of the limit groove 34 and the limit block 35, when the screw rod 27 moves, the limit block 35 will be driven to slide inside the limit groove 34, and then the sliding limit block 35 can limit the screw rod 27 to ensure that the screw rod 27 can move stably. Through the design of the rotating disk 13, since the surface of the rotating disk 13 is provided with a protrusion, and the protrusion is rough in design, it can increase the friction with the finger, thereby facilitating the operator to rotate the rotating disk 13.

[0031] like Figure 3 , Figure 4 and Figure 8 As shown, a square groove is provided inside the sealing plate 4, and the rack 16 can slide inside the square groove. There are four plug-in blocks 8, and each two plug-in blocks 8 form a group. The ends of the plug-in blocks 8 away from the center of the sealing plate 4 are chamfered.

[0032] The above scheme is adopted: through the design of the sealing plate 4, when the threaded block 10 drives the rack 16 to move, the rack 16 will slide inside the square groove, and the sealing plate 4 will not interfere with the movement of the rack 16. Through the design of the plug block 8, since there are four plug blocks 8, the four plug blocks 8 can enter the inside of the socket 12 at the same time, thereby increasing the fixing effect, and the end of the plug block 8 away from the center of the sealing plate 4 is chamfered, which makes it convenient for the plug block 8 to enter the inside of the socket 12.

[0033] The working principle and use process of the present invention: First, the operator installs the battery body 2 inside the sealing shell 1, and then installs the conductive wire on the surface of the electrode body 3, and passes the conductive wire through the outlet hole 14, and then sets the sealing plate 4 on the surface of the top of the sealing shell 1. When the sealing plate 4 is set on the surface of the sealing shell 1, the sealing ring 22 will enter the inside of the sealing groove 23, thereby improving its sealing effect, and then the conductive wire can be connected to the device to be charged, so as to charge the device; After the sealing plate 4 is sleeved on the surface of the sealing shell 1, the rotating disk 13 and the threaded rod 9 can be rotated, and then the threaded block 10 will move on the surface of the threaded rod 9. When the threaded block 10 moves, it will drive the hinge rod 11 to rotate, and the hinge rod 11 will push the slider 6 to move toward each other on the surface of the slide rail 5. Then the slider 6 will drive the connecting plate 7 and the plug block 8 to move into the inside of the plug hole 12, and then the plug block 8 will enter the inside of the plug hole 12, so that the sealing plate 4 is fixed on the surface of the top of the sealing shell 1, and the sealing plate 4 can seal the battery body 2 and the electrode body 3; At the same time, when the threaded block 10 moves, the rack 16 will be linked to move, and the rack 16 will drive the gear 17 and the screw 18 to rotate, and the blocking block 19 will move on the surface of the rotating screw 18, and will squeeze the air inside the air intake pipe 20, and then the squeezed air will enter the inside of the airbag 15. After the air enters the inside of the airbag 15, the airbag 15 will expand, and then the surface of the airbag 15 will contact the conductive wire inside the outlet hole 14, so that the airbag 15 can block the outlet hole 14; When the sealing ring 22 is used for a long time and needs to be replaced, the rotating rod 29 and the gear three 30 can be rotated, the gear three 30 will drive the gear two 26 to rotate, and the screw rod two 27 will slide inside the gear two 26 and the screw rod two 27, and then the screw rod two 27 will pull the limit block one 28 away from the inside of the limit hole 24, thereby canceling the fixation of the plug plate 21 and the sealing ring 22, and then the operator can replace the plug plate 21 and the sealing ring 22, and finally complete the operation process.
