In addition, for simplicity and clarity of understanding, only one of the components having the same structure or function is schematically illustrated or labeled in some of the drawings.

Fig. 1 schematically shows a schematic view of a splash-proof box according to a preferred embodiment of the present invention, as shown, the splash-proof box comprises a bottom box 10 and a box cover 20, the bottom box 10 being pivotally coupled to an outer side wall 21 of the box cover 20 by means of a mounting wall 11, the box cover 20 being shown in an open state. In use, the mounting wall 11 of the back box 10 may be mounted on a surface to be mounted (e.g., a wall), the mounting wall 11 having an opening 12 therein (see fig. 2) for receiving a switch, receptacle, etc. therein. When the box cover 20 is closed, the switch and the socket can be sealed in the sealed space formed by the bottom box 10 and the box cover 20, and the switch and the socket are prevented from being invaded by foreign matters or moisture and the like. When switch, socket need be used, can open lid 20, through the utility model discloses a positioning mechanism keeps lid 20 at certain open position, exposes inside switch, socket for the use.

Fig. 2 and 3 further schematically show exploded views of a splash box according to a preferred embodiment of the present invention, where it can be seen that the box cover 20 has a double-layered side wall, an outer side wall 21 and an inner side wall 22, where the inner side wall 22 may be shorter than at least a part of the outer side wall 21 such that the outer side wall 21 extends beyond the inner side wall 22, in other words, the outer side wall 21 may have a further extension or bulge. The coupling end of the mounting wall 11 coupled with the box cover 20 is provided with a notch 112 having a certain width, and both lateral end surfaces of the notch 112 are respectively provided with trunnions 113 extending into the notch 112, the trunnions 113 serving as a pivot for pivoting the box cover 20 with respect to the base box 10. The end of the outer side wall 21 of the box cover 20 is provided with a boss or an extension 212 capable of being received in the recess 112, and the two ends of the boss 212 in the transverse direction are respectively provided with a pivot connection part 213, and the pivot connection part 213 extends from the outer side wall 21 to the boss 212. The two pivot connection portions 213 are respectively provided with holes matched with the trunnions 113, so that the two pivot connection portions 213 can be sleeved on the trunnions 113 and thus the box cover 20 can be pivotally coupled to the bottom box 10. When the lid 20 pivots about the trunnions 113 relative to the base box 10, the boss 212 pivots within the recess 112 and does not interfere with any portion of the base box 10. In order to enable the lid 20 to be self-positioned with respect to the bottom case 10, one or at least two elastic ribs 211 may be provided at a substantially middle position inside the boss 212, the elastic rib 211 being located between the outer side wall 21 and the inner side wall 22 and extending along the outer side wall 21 to at least a portion of the boss 212, the elastic rib 211 including a glue portion 2113 connected to the inner side wall 22 and an overhang 2111 overhanging the inner side wall 22, an end of the overhang 2111 exceeding the inner side wall 22. The notch 112 is provided with a joint part 111 for engaging and urging the elastic rib 211 to deform elastically, and the elastic rib 211 and the joint part 111 can cooperate to realize self-positioning of the box cover 10. The engagement portion 111 may extend perpendicular to the mounting wall 11 and the resilient rib 211, which may be one of the walls forming the recess 112, or may be provided in the recess. The elastic rib 211 and the engaging portion 111 may be integrally formed with the same material (e.g., polycarbonate material) as the cover 20 and the bottom case 10, respectively. The elastic rib 211 on the lid 20 and the joint 111 of the bottom case 10 together constitute the positioning mechanism of the present invention.

The positioning mechanism of the present invention will be described in detail with reference to fig. 4 to 9. Fig. 4 schematically shows a cross-sectional view of the splatter box in the closed state along the location of the elastic rib 211, and fig. 5 shows an enlarged view of a part of the location of the positioning mechanism in the position of fig. 4, i.e. an enlarged view of the part marked with the letter a in fig. 4. When the lid 20 is closed on the base 10, the ends of the resilient ribs 211 are received in the recesses 112 preferably without contacting or interfering with any part of the base 10, with the resilient ribs 211 in an initial, naturally empty condition. Of course, the ends of the elastic ribs 211 may also contact or interfere with other parts to some extent as long as they do not interfere with the lid 20 being held in the closed position. A notch 2114 may be provided between the inner sidewall 22 and the overhang 2111. When the cover is in the closed state, the end of the engaging portion 111 away from the mounting wall 11 extends into the notch 2114, and the end of the inner side wall 22 abuts against the bottom case 10, thereby improving the waterproof property of the splash box.

Fig. 6 schematically shows a cross-sectional view of the splatter box in a transition between a fully opened state and a closed state, taken along the location of the elastic rib 211, and fig. 7 shows an enlarged view of a part where the positioning mechanism is located, i.e. an enlarged view of the part marked by the letter B in fig. 6. As shown in the figure, the end of the elastic rib 211 is engaged with the engaging portion 111 and interferes with the engaging portion 111 with the rotation of the cap 20, and is deformed by the pressing of the engaging portion 111. The elastic rib 211 acts on the outer sidewall 21 after being deformed and brings the outer sidewall 21 into deformation. Further, the elastic rib 211 is deformed to allow an interference portion (an angular portion as shown in the drawing) of the end of the elastic rib 211 to rotate through the interference area. The elastic deformation of the elastic rib 211 provides resistance to the flip cover 20, and in particular, the required flip force when the cover 20 is flipped can be adjusted by adjusting the rigidity of the elastic rib 211 to provide a comfortable handling feeling. For example, the deformation force required in flipping the lid may be changed by changing the length of the overhang 2111, the longer the length of the overhang 2111, the easier it is to deform, the smaller the flipping force, the shorter the length of the overhang 2111, the less likely it is to deform, and the larger the flipping force. In other words, the shorter the length of the overhang 2111, the longer the length of the adhesive portion 2113; the more glue that is applied, the greater the deformation force required to pull the inner sidewall during deformation of the outer sidewall. The length of the overhang 2111 may be equal to the length of the elastic rib 211 at the most, preferably between 1/4 and 1/3 of the length of the elastic rib 211. Further, a notch 2112 may be provided between the distal end of the elastic rib 211 and the outer side wall 21 to reduce the stiffness of the distal end of the elastic rib 211 to make it more deformable, the depth of the notch 2112 preferably being between 1/7 and 1/6 of the length of the elastic rib 211. In the process of opening or closing the box cover, the end of the elastic rib 211 is deformed by being pressed by the joint part 111, thereby bringing the outer side wall 21 to deform. By providing the notch 2112, the deformation width of the distal end of the elastic rib 211 can be increased, and the deformation width of the outer wall 21 can be decreased.

Fig. 8 schematically shows a cross-sectional view of the splatter box in a fully opened state, taken along the location of the elastic rib 211, and fig. 9 shows an enlarged view of a part of the location of the positioning mechanism in the position of fig. 8, i.e. an enlarged view of the part marked by the letter C in fig. 8. As shown, the elastic rib 211 has been restored to its original shape after being elastically deformed, and the distal corner portion of the elastic rib 211 has been rotated through the interference area with the joint 111, at which time, if the splash box is mounted on a vertical mounting surface (e.g., a wall), the box cover 20 is subjected to downward gravity, and the distal end of the elastic rib 211 abuts against the joint 111 by the gravity. The rigidity of the elastic rib 211 is such that in the absence of an applied external force, the weight of the lid 20 is insufficient to significantly deform the elastic rib 211, thereby maintaining the lid 20 in the fully open position. The opening angle of the lid 20 with respect to the base box 10 is preferably between 80 to 120 degrees when the lid 20 is held in the fully open position.

In another aspect, the present invention also provides a splash box having a positioning mechanism according to the above embodiment, which includes the bottom box 10 and the box cover 20 pivotally coupled to each other as described above. The back box 10 has a mounting wall 11, the mounting wall 11 being mountable on a wall around a switch and/or a socket; the upper portion of the cap 20 has an outer sidewall 21 and an inner sidewall 22 shorter than the outer sidewall, and the distal end of the outer sidewall 21 is pivotably coupled with the upper end of the mounting wall 11. One or at least two elastic ribs 211 extending along the outer side wall and beyond the inner side wall are disposed between the outer side wall 21 and the inner side wall 22, and the elastic ribs 211 can be integrally formed with the box cover 20 through an injection molding process. The portion of the elastic rib 211 that connects the inner sidewall 22 is the glue connection 2113. The elastic rib 211 may have an overhang 2111 with respect to the inner sidewall 22, the length of the overhang 2111 being less than or equal to the length of the elastic rib 211, preferably between 1/4 and 1/3 of the length of the elastic rib 211. A gap 2112 may also be provided between the resilient rib 211 and the outer side wall 21, the depth of the gap 2112 being less than or equal to the length of the overhang 2111, preferably between 1/7 and 1/6 of the length of the resilient rib 211. The mounting wall 11 may be provided at a side thereof away from the wall with an engaging portion 111 extending in a horizontal direction perpendicular to the mounting wall, and the engaging portion 111 may be integrally formed with the bottom case 10 through an injection molding process. In this splash guard, when the cover 20 is in the fully opened state, the end of the elastic rib 211 abuts against the joint part 111 by the weight of the cover and maintains the cover in the fully opened state, and the end of the elastic rib 211 is deformed by being pressed by the joint part 111 in the process of opening and closing the cover by applying an external force.
