Description

Technical Field

[0001] The utility model relates to the technical field of splash-proof boxes. Background Art

[0002] Switches and sockets are indispensable electrical appliances in every household. In places with high moisture, such as bathrooms and toilets, splash-proof boxes are usually installed to prevent water, dust, and particles from entering the switches or sockets to ensure their safe use. The splash-proof box usually consists of a bottom box and a reversible cover. When the cover is closed, the switches and sockets are enclosed in the splash-proof box for protection; when the cover is opened, the switches and sockets are exposed for easy use by users.

[0003] For ease of operation, existing splash-proof boxes usually have a hovering function to facilitate user operation. However, the existing hovering mechanism requires the use of additional shrapnel and springs to achieve hovering through the interference fit between the spring, shrapnel and the box cover, but the spring and shrapnel are relatively strong, and long-term use can easily cause damage to the bottom box. There are also technical solutions in the prior art that use interference fit between the bottom box and the box cover to achieve hovering, such as the invention patent application with application number 202210242868.7 and application name A waterproof box and its waterproof box assembly, but the box cover of this solution can only hover at multiple preset angles, and cannot hover at any position. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and to propose a splash-proof box to solve at least one of the above problems.

[0005] In order to achieve the above technical objectives, the utility model provides a splash-proof box, comprising a bottom box and a box cover, wherein the bottom box comprises a shell and a cavity defined by the shell, the box cover is pivotally connected to the shell so that the box cover can cover the cavity in an openable and closable manner, the shell is provided with a damping block, the box cover comprises an elastic wall, and the box cover has a closed position, an intermediate position and a maximum open position;

[0006] The box cover is in a free rotation area between the closed position and the intermediate position, and the elastic wall is not in contact with the damping block;

[0007] The box cover is in a damping rotation area between the middle position and the maximum opening position, and the elastic wall deformably abuts against the damping block to generate a first damping force, and the first damping force suspends the box cover when overcoming the weight of the box cover.

[0008] Preferably, an outer side of the top of the shell is provided with an integrally formed rib-shaped rib, and the rib-shaped rib forms the damping block.

[0009] Preferably, the rib-like ribs are arranged in a central area of ​​the top of the shell.

[0010] Preferably, a reinforcing rib is provided in the central area inside the top of the shell.

[0011] Preferably, pivot plates are protrudingly provided on both sides of the top of the shell, the box cover is pivotally connected to the pivot plates, and the pivot plates form the damping block.

[0012] Preferably, the pivot plate and the shell are integrally formed.

[0013] Preferably, at least two water retaining ribs are provided, and water guide ribs are provided on the edges of the water retaining ribs not connected to the pivot plate, and the water guide ribs extend in a direction away from the box cover.

[0014] An interference portion is provided on one of the inner side of the box cover and the outer side of the pivot plate. When the box cover is in the damping rotation area, the interference portion rubs against the other to generate a second damping force. The second damping force and the first damping force together suspend the box cover.

[0015] Preferably, the box cover rotates along the pivot axis X1, the upper surface of the damping block forms an abutment surface abutting the elastic wall, the inner surface of the elastic wall forms a deformation surface abutting the abutment portion, and the minimum distance between the abutment surface and the pivot axis X1 is greater than or equal to the minimum distance between the deformation surface and the pivot axis X1.

[0016] Preferably, the abutment surface comprises a first abutment surface and a second abutment surface sequentially arranged along the opening direction of the box cover, the distance between the first abutment surface and the pivot axis X1 gradually increases along the opening direction of the box cover, and the distance between the second abutment surface and the pivot axis X1 gradually decreases along the opening direction of the box cover.

[0017] After adopting the above technical solution, the utility model has the following beneficial effects.

[0018] 1. The utility model proposes a splash-proof box, including a bottom box and a box cover, a damping block is provided on the shell, and the box cover includes an elastic wall. The box cover is in a damping rotation area between the middle position and the maximum opening position, and the elastic wall deforms to abut against the damping block to generate damping, and the box cover is suspended when the damping overcomes the gravity of the box cover. With such a configuration, when the user needs to operate, he does not need to open the box cover to the maximum opening position, and can operate the switch and socket in the splash-proof box; at the same time, when the opening angle of the box cover is insufficient, the user can adjust the opening angle of the box cover by pushing the box cover, and when the user stops pushing the box cover, the box cover can be suspended at any time, and the user's operation is more flexible and convenient; furthermore, for switches or sockets of different sizes and shapes, the box cover with a continuous suspension position can also be better adapted.

[0019] 2. The top of the shell is provided with an integrally formed rib rib, which forms a damping block. By providing an integrally formed rib rib on the outer side of the shell, the shell can be formed by injection molding in one step, without the need to produce two parts separately or assemble them, thereby reducing the production cost of the bottom box.

[0020] 3. The top of the shell is provided with an integrally formed rib-shaped rib, which forms a damping block. The rib-shaped rib is arranged in the central area of ​​the top of the shell. In this way, the elastic wall of the box cover is stressed in the center, and the reaction force of the rib-shaped rib against the elastic wall acts on the central area of ​​the box cover, so that the force on the box cover is relatively balanced, and the user feels better when pushing the box cover to rotate; at the same time, the pivot connection between the box cover and the bottom box is also balanced, and there will be no excessive force on one side of the pivot structure, which will lead to an increase in wear on one side, thereby improving the service life of the pivot structure and the stability of the box cover rotation.

[0021] 4. A reinforcing rib is provided in the central area on the inner side of the top of the shell. By providing the reinforcing rib, the structural strength of the central area on the top of the shell can be strengthened, and the downward deformation of the central area on the top of the shell caused by the elastic wall abutting against the rib-shaped rib can be reduced, thereby increasing the service life of the bottom box. At the same time, the interference between the elastic wall and the rib-shaped rib is greater, which increases the damping force available for the box cover to hover, making the box cover hover more stable.

[0022] 5. Pivot plates are protruding on both sides of the top of the shell, and the box cover is pivotally connected to the pivot plates, and the pivot plates form damping blocks. The shell includes side walls on both sides, and the pivot plates are arranged on both sides of the top of the shell. The cantilever distance between the pivot plates and the side walls of the shell is small, so that the shell at the position connected with the pivot plates has high compressive and torsional strengths. The pivot plates form damping blocks, and when the elastic wall abuts against the pivot plates, the shell at the position connected with the pivot plates is not easy to deform, thereby improving the service life of the splash-proof box.

[0023] 6. By integrally forming pivot plates on both sides of the top of the shell, the shell can be formed by injection molding in one step, without the need to produce two parts separately or assemble them, thereby reducing the production cost of the bottom box; at the same time, the one-piece molding has better structural strength than assembly, and because there is no need to consider assembly, the wall thickness of the material can also be thinned, thereby saving materials while ensuring the strength of both sides of the top of the shell, further reducing the cost of the splash-proof box.

[0024] 7. At least one water retaining rib is provided on the top of the shell, and the pivot plate is connected to one of the water retaining ribs. Such an arrangement makes the pivot plate have better strength, and the pivot connection between the box cover and the bottom box is more reliable and stable.

[0025] 8. At least two water retaining ribs are provided. The edges of the water retaining ribs that are not connected to the rib-shaped ribs are provided with water guide ribs, which extend in a direction away from the box cover. This arrangement prevents the flowing water from passing through the joint between the bottom box and the box cover and entering the cavity of the bottom box, thereby preventing the switches or sockets in the bottom box from getting wet or getting damp.

[0026] 9. An interference part is provided on one of the inner side of the box cover and the outer side of the pivot plate. When the box cover is in the damping rotation area, the interference part rubs against the other to generate a second damping force. The second damping force and the first damping force together suspend the box cover. With this arrangement, the interference part adds an additional second damping force for suspension. When the first damping force is not large enough, the second damping force and the first damping force together realize the suspension of the box cover, thereby further optimizing the suspension effect of the box cover. At the same time, when the damping block is gradually worn out with use, the interference part can provide additional suspension damping, so that the splash-proof box can still have a good suspension effect after long-term use, thereby improving the service life of the splash-proof box and the user's experience.

[0027] 10. The damping block includes an abutting surface abutting against the elastic wall, the elastic wall includes a deformation surface abutting against the abutting portion, and the minimum distance between the abutting surface and the pivot axis X1 is greater than or equal to the minimum distance between the deformation surface and the pivot axis X1. The damping block and the elastic wall are directly abutted against each other, so that the box cover has a continuous hovering position, the contact between the two is more direct, and the reliability and stability of the hovering are better.

[0028] 11. The abutting surface includes a first abutting surface and a second abutting surface sequentially arranged along the opening direction of the box cover, the distance between the first abutting surface and the pivot axis X1 gradually increases along the opening direction of the box cover, and the distance between the second abutting surface and the pivot axis X1 gradually decreases along the opening direction of the box cover. With such arrangement, the splash-proof box can be arranged such that when the box cover is opened to an angle convenient for user operation, the box cover has sufficient hovering force or reaches the maximum hovering force, thereby ensuring the hovering effect of the box cover; when the box cover continues to open beyond a certain angle, there is less pressure between the elastic wall and the damping block, so that the deformation of the elastic wall is smaller, which increases the service life of the box cover while ensuring the hovering of the box cover, and also saves more effort for the user when continuing to open or close the box cover.

[0029] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In the prior art, there are splash-proof boxes with multiple preset hovering angles. When the opening angle of the box cover is insufficient, the user needs to continue to push the box cover to open. When the pushing force is insufficient or the box cover is not pushed to the next preset position, the box cover cannot hover at a suitable angle. The splash-proof box of the utility model has ribs on the bottom box and elastic walls on the box cover. The ribs continuously interfere with the elastic walls on at least part of the rotation path of the elastic walls, so that the box cover can hover at any hovering position, thereby providing a better user experience.

[0043] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] Embodiment 1:

[0048] like Figures 1 to 8 As shown, a splash-proof box proposed in an embodiment of the utility model includes a sealing ring 300, a bottom box 100 and a box cover 200. The sealing ring 300 is attached to the back of the bottom box 100 to play a role of waterproof and dustproof. The bottom box 100 includes a shell 110 and a cavity defined by the shell 110. The splash-proof box is installed on the wall, and the switch or socket is placed in the cavity.

[0049] Among them, a pivot hole 201 is provided on the box cover 200, and a pivot 111 is provided on the base box 100. The box cover 200 and the base box 100 are pivotally connected to the pivot 111 through the pivot hole 201, so that the box cover 200 can be opened and closed to cover the cavity. The box cover 200 is opened to reveal the switch and the socket, and the box cover 200 is closed to seal the switch and the socket.

[0050] In some other embodiments, the box cover 200 may be provided with a pivot 111 , and the bottom box 100 may be provided with a pivot hole 201 .

[0051] The box cover 200 rotates relative to the bottom box 100 to have a closed position, an intermediate position and a maximum open position. The box cover 200 is in a free rotation area between the closed position and the intermediate position, and the box cover 200 rotates freely in the free rotation area. The box cover 200 is in a damped rotation area between the intermediate position and the maximum open position, and the box cover 200 rotates damped in the damped rotation area. When the damping overcomes the gravity of the box cover 200, the box cover 200 can be in a suspended state, and the user can loosen the box cover 200 to operate the switch or socket.

[0052] Wherein, a damping block is provided on the housing 110, and the box cover 200 includes an elastic wall 210. When the box cover 200 is in the damping rotation area, the elastic wall 210 deformably abuts against the damping block, and the pressure of the abutment between the two generates damping. When the damping moment generated by the damping relative to the pivot axis is balanced with the self-weight moment generated by the gravity of the box cover relative to the pivot axis, the box cover 200 can be suspended relative to the bottom box 100. The damping block and the elastic wall 210 can be arranged to balance the moment on at least a part of the continuous rotation path between the middle position and the maximum opening position of the box cover 200, so that the box cover 200 can arbitrarily hover at a part of the position between the middle position and the maximum opening position.

[0053] With such arrangement, the user does not need to open the box cover 200 to the maximum opening position when operating, and can operate the switches and sockets in the splash-proof box; at the same time, when the opening angle of the box cover 200 is insufficient, the user can adjust the opening angle of the box cover 200 by pushing the box cover 200; when the user stops pushing the box cover 200, the box cover 200 can hover at any time, and the user's operation is more flexible and convenient; furthermore, the box cover 200 with a continuous hovering position can also better adapt to switches or sockets of different sizes and shapes.

[0054] In this embodiment, an integrally formed rib rib 112 is convexly provided on the outer side of the shell 110 near the pivoting side of the bottom box 100, and the rib rib 112 forms a damping block. The box cover 200 includes an elastic wall 210 near the pivoting side, and the box cover 200 rotates to drive the elastic wall 210 to rotate around the pivot axis X1, and the rib rib 112 interferes with the elastic wall 210 on at least a part of the continuous rotation path of the elastic wall 210, and the elastic wall 210 acts on the rib rib 112 in a deformed manner, and the deformation causes pressure to be generated between the elastic wall 210 and the rib rib 112, and the pressure increases the damping between the elastic wall 210 and the rib rib 112, so that the box cover 200 is in a suspended state. By convexly providing the integrally formed rib rib 112 on the outer side of the shell 110, the shell 110 can be formed by injection molding at one time, without the need to produce two parts separately, and without the need to assemble, thereby reducing the production cost of the bottom box 100.

[0055] In some other embodiments, a plurality of rib-shaped ribs 112 may be provided. Such a configuration can reduce the pressure between a single rib-shaped rib 112 and the elastic wall 210, thereby increasing the durability of the rib-shaped rib 112 and the elastic wall 210, and further improving the service life of the splash-proof box.

[0056] It is understandable that the rib-like ribs 112 can be arranged perpendicular to the pivot axis X1, or can be arranged inclined to the pivot axis X1, and there needs to be a certain angle between the two.

[0057] In a preferred embodiment, Figures 6 to 8 As shown, the rib 112 includes an abutting surface 113 abutting against the elastic wall 210, the elastic wall 210 includes a deformation surface 211 abutting against the abutting portion, the minimum distance between the abutting surface 113 and the pivot axis X1 is D1, the minimum distance between the deformation surface 211 and the pivot axis X1 is D2, and D1>=D2. Through the direct surface-to-surface abutment between the rib 112 and the elastic wall 210, the box cover 200 is realized to have a continuous hovering position, the contact between the two is more direct, and the reliability and stability of the hovering are better.

[0058] This embodiment is more preferably, as Figures 6 to 8 As shown, the abutment surface 113 includes a first abutment surface 1131 and a second abutment surface 1132 sequentially arranged along the opening direction of the box cover 200, the distance between the first abutment surface 1131 and the pivot axis X1 gradually increases along the opening direction of the box cover 200, and the distance between the second abutment surface 1132 and the pivot axis X1 gradually decreases along the opening direction of the box cover 200.

[0059] When the box cover 200 is opened to a certain angle (for example, the angle between the box cover 200 and the bottom box 100 is between 40° and 60°), the user can operate the switch or socket, but because the horizontal distance between the ends of the box cover 200 is large, the force arm is large, and the damping required for the box cover 200 to hover is large. When the box cover 200 continues to open, as the horizontal distance between the ends of the box cover 200 decreases, the force arm gradually decreases, and the damping required for the box cover 200 to hover also gradually decreases.

[0060] When the box cover 200 is opened, the elastic wall 210 contacts the first abutting surface 1131, and the pressure between the two gradually increases. When the box cover 200 is opened to a certain angle (for example, the angle between the box cover 200 and the bottom box 100 is between 40° and 60°), the damping between the two reaches a certain value, and the box cover 200 can hover relative to the bottom box 100. When the elastic wall 210 is rotated to the farthest position between the first abutting surface 1131 and the pivot axis X1, the pressure between the two reaches the maximum value, and the hovering effect is the best at this time. The box cover 200 continues to rotate, and the damping required for the box cover 200 to hover gradually decreases. The elastic wall 210 contacts the second abutting surface 1132, and the pressure between the two gradually decreases. The box cover 200 can still hover at any position; at the same time, as the elastic wall 210 rotates, the contact area between the two gradually increases, and the pressure required to maintain the damping between the elastic wall 210 and the rib-shaped rib 112 can be further reduced. When the box cover 200 is rotated to the maximum open position, the box cover 200 is in a vertical or nearly vertical position, and the damping required for the box cover 200 to hover is relatively small. The elastic wall 210 and the second abutting surface 1132 abut against each other with a small pressure, so that the box cover 200 remains in a hovering state.

[0061] With such arrangement, the splash-proof box can be arranged so that when the box cover 200 is opened to an angle convenient for user operation, the box cover 200 has sufficient hovering force or reaches the maximum hovering force, thereby ensuring the hovering effect of the box cover 200; when the box cover 200 continues to be opened beyond a certain angle, the box cover 200 abuts against the second abutting surface 1132, and when the maximum opening angle is reached, the pressure between the elastic wall 210 and the rib-shaped rib 112 gradually decreases. Because users are usually accustomed to opening the box cover 200 as wide as possible during use, or even directly open it to the maximum opening angle, such a design makes the deformation of the elastic wall 210 near the maximum opening angle smaller, thereby increasing its service life while ensuring the hovering of the box cover 200, and also saving effort for users when continuing to open or close the box cover 200.

[0062] In some other embodiments, a mating rib abutting against the rib-like rib 112 is convexly provided on the inner side of the elastic wall 210. The mating rib abuts against the rib-like rib 112 so that the box cover 200 has a continuous hovering position, thereby preventing the rib-like rib 112 from repeatedly rubbing against the elastic wall 210 and causing grooves or even damage to the elastic wall 210, thereby increasing the service life of the splash-proof box.

[0063] Embodiment 2:

[0064] Based on the first embodiment, Figure 1 , Figure 2As shown, in this embodiment, the rib 112 is arranged in the central area of ​​the outer side of the top of the shell 110. In this way, the elastic wall 210 of the box cover 200 is stressed in the center, and the reaction force of the rib 112 abutting against the elastic wall 210 acts on the central area of ​​the box cover 200, so that the force on the box cover 200 is relatively balanced, and the user feels better when pushing the box cover 200 to rotate; at the same time, the pivot connection between the box cover 200 and the bottom box 100 is also balanced, and there will be no excessive force on one side of the pivot structure, which will lead to an increase in wear on one side, thereby improving the service life of the pivot structure and the stability of the rotation of the box cover 200.

[0065] In this embodiment, reinforcing ribs are preferably provided in the central area of ​​the top inner side of the shell 110. By providing the reinforcing ribs, the structural strength of the central area of ​​the top of the shell 110 can be strengthened, and the downward deformation of the central area of ​​the top of the shell 110 caused by the elastic wall 210 abutting against the rib-shaped ribs 112 can be reduced, thereby increasing the service life of the bottom box 100. At the same time, the interference between the elastic wall 210 and the rib-shaped ribs 112 is greater, thereby increasing the damping force for the box cover 200 to suspend, and making the box cover 200 suspend more stably.

[0066] For other contents not described in this embodiment, please refer to Embodiment 1.

[0067] Embodiment three:

[0068] Based on the first and second embodiments, Figure 1 , Figure 2 As shown, in this embodiment, three water retaining ribs 114 are provided on the top of the shell 110 , and the rib-shaped rib 112 is connected to one of the water retaining ribs 114 .

[0069] A water retaining rib 114 is provided on the top of the shell 110. When the box cover 200 is closed on the bottom box 100, external water enters the top of the shell 110 from the gap between the two, is blocked by the water retaining rib 114, and is guided by the water retaining rib 114 to flow away from both sides.

[0070] The rib 112 is connected to the water retaining rib 114, which increases the structural strength of the rib 112 and the water retaining rib 114, and increases the strength of the rib 112 while increasing the service life of the water retaining rib 114. The rib 112 is not easily deformed when abutting against the elastic wall 210, thereby ensuring the hovering effect of the box cover 200 and the service life of the splash-proof box.

[0071] It is understandable that the water retaining rib 114 can be one or more. The multiple water retaining ribs 114 can gradually and multiple times block the external water, thereby improving the waterproof effect of the splash-proof box. The rib rib 112 can be connected to any one of the water retaining ribs 114.

[0072] In this embodiment, the top of the housing 110 is preferably provided with a pivot plate 116 on both sides, the pivot plate 116 is provided with a pivot shaft 111, the box cover 200 is provided with a pivot hole 201, the pivot hole 201 is sleeved on the pivot shaft 111, so that the box cover 200 is pivotally connected with the pivot plate 116, and the pivot plate 116 is connected with one of the water retaining ribs 114. Such a configuration makes the pivot plate 116 have better strength, thereby improving the reliability and stability of the pivot connection between the bottom box 100 and the box cover 200.

[0073] For other contents not described in this embodiment, reference may be made to the aforementioned embodiments.

[0074] Embodiment 4:

[0075] like Figure 1 , Figure 3 As shown, different from embodiments one to three, pivot plates 116 are protruded from both sides of the top of the shell 110, a pivot 111 is provided on the pivot plate 116, a pivot hole 201 is provided on the box cover 200, and the pivot hole 201 is sleeved on the pivot 111, so that the box cover 200 is pivotally connected to the pivot plate 116, and the pivot plate 116 extends in a direction away from the pivot axis X1 to form a damping block.

[0076] In some other embodiments, the pivot plate 116 may be provided with a pivot hole 201 , and the box cover 200 may be provided with a pivot shaft 111 .

[0077] Because the shell 110 includes side walls on both sides, the pivot plate 116 is arranged on both sides of the top of the shell 110, and the cantilever distance between the pivot plate 116 and the side wall of the shell 110 is small, so that the shell 110 at the connection position with the pivot plate 116 has higher compressive and torsional strengths, and the pivot plate 116 forms a damping block. When the elastic wall 210 abuts against the pivot plate 116, the shell 110 at the connection position with the pivot plate 116 is not easy to deform, thereby improving the service life of the splash-proof box.

[0078] In a preferred embodiment, Figures 6 to 8 As shown, the pivot plate 116 includes an abutting surface 113 abutting against the elastic wall 210, and the elastic wall 210 includes a deformation surface 211 abutting against the abutting portion. The minimum distance between the abutting surface 113 and the pivot axis X1 is D1, and the minimum distance between the deformation surface 211 and the pivot axis X1 is D2, and D1>=D2. Through the direct surface-to-surface abutment between the pivot plate 116 and the elastic wall 210, the box cover 200 has a continuous hovering position, the contact between the two is more direct, and the reliability and stability of the hovering are better.

[0079] This embodiment is more preferably, as Figures 6 to 8As shown, the abutment surface 113 includes a first abutment surface 1131 and a second abutment surface 1132 sequentially arranged along the opening direction of the box cover 200, the distance between the first abutment surface 1131 and the pivot axis X1 gradually increases along the opening direction of the box cover 200, and the distance between the second abutment surface 1132 and the pivot axis X1 gradually decreases along the opening direction of the box cover 200.

[0080] With such arrangement, the splash-proof box can be arranged so that when the box cover 200 is opened to an angle convenient for user operation, the box cover 200 has sufficient hovering force or reaches the maximum hovering force, thereby ensuring the hovering effect of the box cover; when the box cover 200 continues to be opened beyond a certain angle, the box cover 200 abuts against the second abutting surface 1132, and from then on to the maximum opening angle, the pressure between the elastic wall 210 and the pivot plate 116 gradually decreases. Because users are usually accustomed to opening the box cover 200 as much as possible when using it, or even directly open it to the maximum opening angle, such a design makes the deformation of the elastic wall 210 near the maximum opening angle smaller, thereby increasing its service life while ensuring that the box cover 200 hovers, and it is also more labor-saving for users to continue to open or close the box cover 200.

[0081] In another preferred embodiment, the pivot plate 116 is integrally formed with the housing 110. By integrally forming the pivot plate 116 on both sides of the top of the housing 110, the housing 110 can be formed by injection molding at one time, without the need to produce two parts separately or assemble them, thereby reducing the production cost of the bottom box 100; at the same time, the structural strength of the integral molding is better than that of the assembly, and since there is no need to consider assembly, the wall thickness of the material can also be thinned, thereby saving materials on the basis of ensuring the strength of both sides of the top of the housing 110, further reducing the cost of the splash-proof box.

[0082] In another preferred embodiment, Fig. 9 As shown, the inner side of the box cover 200 is provided with an interference part 220. When the box cover 200 is in the damping rotation area, the interference part 220 and the pivot plate 116 are rubbed against each other to generate a second damping force, and the second damping force and the first damping force together suspend the box cover 200. In this way, the interference part 220 adds an additional second damping force for suspension. When the first damping force is not large enough, the second damping force and the first damping force together realize the suspension of the box cover 200, thereby further optimizing the suspension effect of the box cover 200; at the same time, when the damping block is gradually worn out with use, the interference part 220 can provide additional suspension damping, so that the splash-proof box can still have a good suspension effect after long-term use, thereby improving the service life of the splash-proof box and the user's experience.

[0083] In this embodiment, the interference portion 220 is a cylindrical protrusion, which rubs against the pivot plate 116 to generate the second damping force. In other embodiments, the interference portion 220 can be a protrusion of other shapes, or the interference portion 220 can be a thickened inner wall of the cover 200 at a position opposite to the pivot plate 116.

[0084] It is understandable that the interference portion 220 can also be set on the outside of the pivot plate 116. When the box cover 200 is in the damping rotation area, the interference portion 220 and the box cover 200 rub against each other to generate a second damping force. The second damping force and the first damping force together suspend the box cover 200.

[0085] In another preferred embodiment, three water retaining ribs 114 are disposed on the top of the shell 110 , and the rib-shaped rib 112 is connected to one of the water retaining ribs 114 .

[0086] A water retaining rib 114 is provided on the top of the shell 110. When the box cover 200 is closed on the bottom box 100, external water enters the top of the shell 110 from the gap between the two, is blocked by the water retaining rib 114, and is guided by the water retaining rib 114 to flow away from both sides.

[0087] The pivot plate 116 is connected to the water retaining rib 114, which increases the structural strength of the pivot plate 116 and the water retaining rib 114, and increases the strength of the pivot plate 116 while increasing the service life of the water retaining rib 114. The pivot plate 116 is not easily deformed when abutting against the elastic wall 210, thereby ensuring the hovering effect of the box cover 200 and the service life of the splash-proof box.

[0088] It is understandable that the water retaining rib 114 can be one or more. The multiple water retaining ribs 114 can block the external water step by step and multiple times, thereby improving the waterproof effect of the splash-proof box. The pivot plate 116 can be connected to any one of the water retaining ribs 114.

[0089] For other contents not described in this embodiment, reference may be made to the aforementioned embodiments.

[0090] Embodiment five:

[0091] Based on the third and fourth embodiments, Figures 2 to 4 As shown, in this embodiment, the edge of the water retaining rib 114 that is not connected to the rib-shaped rib 112 is provided with a water guiding rib 115 , and the water guiding rib 115 extends in a direction away from the box cover 200 .

[0092] Among them, the water guide rib 115 is attached to the outer side of the shell body 110. The water blocked by the water retaining rib 114 flows down from both ends of the water retaining rib 114 and is guided by the water guide rib 115 to make the flowing water flow down at a position away from the box cover 200 on the outer side of the shell body 110, thereby preventing the flowing water from passing through the joint between the bottom box 100 and the box cover 200 and entering the cavity of the bottom box 100, thereby preventing the switch or socket in the bottom box 100 from being flooded or damp.

[0093] In this embodiment, a drainage groove 117 is preferably provided on the side of the housing 110, and a drainage port 118 is provided at the bottom of the housing 110. In this way, the water flow guided by the water guide rib 115 flows into the drainage groove 117 and flows down along the drainage groove 117 to the bottom of the housing 110 and then is discharged from the drainage port 118, thereby further preventing the flowing water from entering the cavity of the bottom box 100; at the same time, the flowing water is discharged from the drainage port 118 at the bottom, thereby preventing water from accumulating in the splash-proof box and causing an increase in internal humidity, and better preventing the switch or socket in the splash-proof box from getting damp.
