Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-6This utility model provides a technical solution: a sealed battery cover for a storage battery, comprising: a storage box 1, with positive and negative electrode slots 2 formed on the outer wall of the top of the storage box 1, and a middle cover structure 3 slidably connected to the inner wall of the top of the storage box 1; the middle cover structure 3 includes a cover body 31, with a groove 32 formed on the outer wall of the top of the cover body 31, a handle 33 rotatably connected to the inner wall of the groove 32, a support rod 35 fixedly connected to the inner wall of the cover body 31, a baffle 36 rotatably connected to the outer wall of the support rod 35, and torsion springs 37 symmetrically fixedly connected to the outer wall of the side of the baffle 36. The outer wall of the torsion spring 37 away from the baffle 36 is fixedly connected to the inner wall of the cover 31. The outer wall of the baffle 36 is provided with a handle groove 38, and the outer wall of the bottom of the baffle 36 is symmetrically provided with wire grooves 39. The outer wall of the bottom of the baffle 36 is in contact with the inner wall of the positive and negative pole grooves 2. When the positive and negative poles are needed, the baffle 36 can be rotated along the support rod 35 through the handle groove 38 to overcome the torque of the torsion spring 37, so that the baffle 36 can be opened to expose the positive and negative pole grooves 2, which is convenient for wiring and other operations. The outer wall of the bottom of the cover 31 is in contact with the outer wall of the top of the battery box 1.
[0027] The outer wall of the bottom of the cover 31 is symmetrically provided with sliding grooves 311, the inner wall of the sliding grooves 311 is symmetrically fixedly connected with sliding rods 312, the outer wall of the sliding rods 312 is slidably connected with clamping blocks 313, and the outer wall of the clamping blocks 313 is symmetrically fixedly connected with pressure springs 314.
[0028] The outer wall of the pressure spring 314 away from the clamping block 313 is fixedly connected to the inner wall of the slide groove 311. The outer wall of the clamping block 313 is slidably connected to the inner wall of the slide groove 311. When the clamping block 313 is subjected to force and moves inward, it will slide inward along the slide groove 311 through the slide rod 312, and at the same time, the pressure spring 314 is squeezed and stored.
[0029] A pressure plate 315 is fixedly connected to the outer wall of the bottom of the cover 31. A sealing gasket 316 and a sliding column 317 are fixedly connected to the outer wall of the bottom of the pressure plate 315, and the sliding column 317 and the sealing gasket 316 are arranged in an array along the outer wall of the bottom of the pressure plate 315.
[0030] The outer wall of the top of the battery box 1 is symmetrically provided with clamping grooves 11, and the outer wall of the top of the battery box 1 is provided with mounting grooves 12. The inner wall of the bottom of the mounting groove 12 is fixedly connected with an inlet pipe 13.
[0031] The inner wall of the clamping groove 11 is slidably connected to the outer wall of the clamping block 313, the inner wall of the mounting groove 12 is slidably connected to the outer wall of the pressure plate 315, the inner wall of the liquid inlet pipe 13 is slidably connected to the outer wall of the sliding column 317, and the outer wall of the top of the liquid inlet pipe 13 is in contact with the outer wall of the bottom of the sealing gasket 316. When the pressure plate 315 is inserted into the mounting groove 12, the sliding column 317 will be inserted into the inner wall of the liquid inlet pipe 13, and at the same time the sealing gasket 316 will be in close contact with the top outer wall of the liquid inlet pipe 13, forming a good sealing effect to prevent electrolyte leakage and external impurities from entering the battery box 1.
[0032] In use, the middle cover structure 3 is connected to the clamping groove 11 on the battery box 1 through the clamping block 313 to achieve installation and fixation. At the same time, the baffle 36 can protect the positive and negative terminal grooves 2, reducing dust and oil stains adhering to the positive and negative terminals and causing electrical hazards. In addition, the handle 33 rotatably connected in the groove 32 can be rotated and lifted out of the groove 32 when the battery needs to be moved, making it convenient for the operator to hold and move the battery.
[0033] When the middle cover structure 3 needs to be installed, the cover 31 is aligned with the top of the battery box 1. The clamping block 313 in the symmetrical groove 311 on the outer wall of the bottom of the cover 31 is in an outward expansion state under the action of the pressure spring 314. When the cover 31 is put down, the clamping block 313 will align and contact the symmetrical groove 11 on the outer wall of the top of the battery box 1. As the cover 31 is pressed down, it is squeezed through the inclined surface of the outer wall of the clamping block 313 and slides inward along the groove 311 through the slide rod 312. At the same time, the pressure spring 314 is squeezed and stored. When the cover 31 contacts and closes with the battery box 1, the clamping block 313 enters the groove at the bottom of the groove 11 under the push of the pressure spring 314, thereby fixing the middle cover structure 3 to the battery box 1. Conversely, pressing the clamping block 313 can pull it out from the groove at the bottom of the groove 11 to complete the disassembly.
[0034] As the cover 31 closes, the pressure plate 315 at the bottom of the cover 31 will slide into the mounting groove 12 at the top of the battery box 1. When the pressure plate 315 is inserted into the mounting groove 12, the sliding column 317 will be inserted into the inner wall of the liquid inlet pipe 13. At the same time, the sealing gasket 316 will be in close contact with the outer wall at the top of the liquid inlet pipe 13 to form a good sealing effect, preventing electrolyte leakage and external impurities from entering the battery box 1, and ensuring the normal operation of the battery.
[0035] After closing, under the action of the torsion spring 37, the bottom outer wall of the baffle 36 contacts the inner wall of the positive and negative pole slots 2. When the positive and negative poles are needed, the baffle 36 can be rotated along the support rod 35 by moving the slot 38 to overcome the torque of the torsion spring 37, so that the baffle 36 is opened to expose the positive and negative pole slots 2, which facilitates wiring and other operations. After the operation is completed, the baffle 36 is released, and under the action of the torsion spring 37, the baffle 36 automatically resets to continue to protect the positive and negative pole slots 2. At the same time, the connecting wire is also locked in the wire slot 39.
