[0027] Referring to Figure 4 A relief groove 5 is formed in the lateral wall of install hole 3, a positioning block 51 is slidably installed in the relief groove 5, a spring 52 is fixedly installed between the positioning block 51 and the relief groove 5, the end away from the relief groove 5 of the positioning block 51 is provided in an isosceles triangular shape, and a positioning groove 53 adapted with the positioning block 51 is formed in the outer lateral wall of the sleeve pipe 31; the positioning block 51 can emit a crisp sound to remind the user that the screw 34 has been installed in place, thereby avoiding sealing problems caused by tightening or loosening too much and improving the safety and stability of use.

[0028] Referring to Figure 5 A storage bin 6 is formed in the lateral wall of the cover body 1, an operating handle 61 is arranged in the storage bin 6, a keyless chuck 62 is fixedly installed at one end of the operating handle 61, an installation plate 63 adapted with the fixing block 42 is fixedly installed at the other end of the operating handle 61, the installation plate 63 and the fixing block 42 are made of magnets, and a baffle 64 is arranged on the storage bin 6; tools adapted with the screw 34 and the limiting ring 35 are arranged in the storage bin 6, which facilitates the installation of the cover body 1 and the disassembly of the limiting ring 35, the magnetic attraction can facilitate the removal of the limiting ring 35, and the falling or loss of the limiting ring 35 is avoided.

[0029] Referring to Figure 5Two fixed plates 7 are symmetrically fixed and installed in the length direction of the storage bin 6, two sliding blocks 71 adapted to the fixed plates 7 are fixedly installed on the baffle 64 away from the sealing strip 2, and the inner side wall of the storage bin 6 and the fixed plate 7 are all slidingly connected with the sliding block 71; the storage bin 6 can be opened by sliding the baffle 64, and the cover body 1 can be positioned on the vertical plane by the baffle 64, so as to facilitate the installation and fixation of the waterproof box.

[0030] With reference to Figure 5 A protrusion 72 is fixedly installed on the end of the fixed plate 7 away from the operating handle 61 and located away from the sealing strip 2, and a recess 73 adapted to the protrusion 72 is formed in the sliding block 71; the interference fit of the protrusion 72 and the recess 73 can fix the baffle 64, so as to ensure that the baffle 64 cannot be accidentally opened after being closed, and the tool is protected from being lost.

[0031] The specific working principle of the utility model is as follows:

[0032] In use, the cover body 1 is aligned with the waterproof box, a tool can be directly used to pass through the center hole on the limiting ring 35 to screw the screw 34 into the waterproof box, and in the process of tightening, the screw 34 drives the sleeve 31 and the limiting ring 35 to move synchronously until the fixation is completed, and when disassembling, the tool can also be used to pass through the center hole on the limiting ring 35 to unscrew the screw 34, but the screw 34 is wrapped in the middle by the limiting ring 35 and the sleeve 31, and the sleeve 31 can only slide in the mounting hole 3 under the action of the guide block 33 and the guide groove 32, so that when the waterproof cover is removed, the screw 34 can be retained on the cover body 1, avoiding the operation of carrying and taking and placing the screw 34 alone, making the use of the waterproof box cover more simple and convenient, and avoiding the situation that the screw 34 is lost and the waterproof box cover cannot be used, ensuring that the cover body 1 can work normally at any time, and the cover body 1 can be adjusted in position by the fact that the sleeve 31 can slide in the mounting hole 3, facilitating positioning and installation;

[0033] By cooperating with the fixed block 42, the limiting ring 35 can be driven to rotate, and under the positioning action of the guide groove 32 and the guide block 33, the limiting ring 35 is relatively rotated with the sleeve 31, so that the L-shaped clamping block 41 is separated from the L-shaped clamping groove 4, at this time, the screw 34 can be removed, so that when the screw 34 is damaged or has other problems, the screw 34 can be replaced, without the need to replace the entire cover body 1, improving the adaptability and service life of the waterproof box cover;

[0034] When the waterproof box cover is screwed to the proper position by the screw 34, the positioning block 51 is extended to the position slot 5 and clamped into the positioning slot 53 under the action of the spring 52, at this time, the clamping movement of the positioning block 51 will emit a crisp sound, thereby reminding the user that the screw 34 has been installed in place, avoiding the damage to the sealing strip 2 caused by over-tightening, thereby affecting the sealing effect and service life of the waterproof box cover, at the same time, it can avoid the incomplete sealing caused by over-looseness, thereby improving the safety and stability of use, and being more convenient for the user to judge the installation state of the waterproof box cover;

[0035] The baffle 64 can slide along the slide formed by the fixed plate 7 and the inner wall of the storage compartment 6 through the sliding block 71, and then slide along the side wall of the cover body 1, for the use scene that needs to be installed vertically, the baffle 64 can be set at the position of the pre-installed top, at this time, the baffle 64 is placed on the waterproof box by sliding towards the waterproof box before installation, so that the cover body 1 is positioned on the vertical surface through the action of gravity and contact with the waterproof box, which can free the hands of the user and facilitate the user to install and fix the waterproof box. The storage compartment 6 is provided with tools matched with the screw 34 and the limiting ring 35, which facilitates the installation of the cover body 1 and the disassembly of the limiting ring 35, and the magnetic attraction can facilitate the removal of the limiting ring 35 after disassembly, which is convenient to operate and can avoid the falling or loss of the limiting ring 35. In addition, the interference fit of the protrusion 72 and the recess 73 can fix the baffle 64 when it is closed, thereby protecting the tools from being lost.

[0036] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
