Splash box

Abstract

This utility model discloses a splash-proof box, including a mounting base and a cover movably mounted on the mounting base. The mounting base has a through-groove, and the inner wall of the mounting groove has a lug for positioning and mounting. At the connection point between the root of the lug and the inner wall, there is a through groove in the middle and through holes spaced at both ends of the through groove. In this splash-proof box, the through groove in the middle forms a main fracture groove, and the through holes at both ends form corresponding weak points. The through groove and through holes create a fracture-resistant structure. When a socket has a rib that interferes with the lug, the fracture-resistant structure formed by the through groove and through holes allows the lug to be directly broken off or pried off using a screwdriver or other tool inserted into the through groove. This effectively improves the applicability of the splash-proof box, making it compatible with different socket types.

Description

Technical Field

[0001] This utility model relates to the field of socket accessories, specifically a splash-proof box. Background Technology

[0002] Splash-proof boxes are widely used as components to protect switches and sockets. The mainstream products on the market currently include through-hole splash-proof boxes and lug-type splash-proof boxes. Through-hole splash-proof boxes lack an effective positioning structure, making them prone to misalignment during installation, leading to positional deviations between the switch / socket and the splash-proof box. Lug-type splash-proof boxes have lugs for positioning, which, while able to achieve positioning through the engagement of the lugs with mounting screws, can interfere with the lugs when there are protruding ribs on the bottom of the switch / socket. This prevents the switch from being fully installed, requiring the replacement of the entire splash-proof box, resulting in resource waste. Utility Model Content

[0003] To address the above issues, this utility model provides a splashproof box that effectively improves the applicability of the splashproof box in different installation scenarios by making the lugs a removable structure.

[0004] The present invention provides a splashproof box, including a mounting base and a cover movably mounted on the mounting base. The mounting base has a through mounting groove, and the inner side wall of the mounting groove has a lug for positioning and mounting. The root of the lug and the inner side wall have a through groove in the middle and through holes at the two ends of the through groove.

[0005] According to the above technical solution, the through groove is located in the middle to form the main fracture groove, and the through hole is located at both ends to form corresponding weak points. The through groove and through hole can form a fracture structure. When the socket has a rib that interferes with the lug, the fracture structure formed by the through groove and through hole can directly break the lug or pry it off by inserting a screwdriver or other tools into the through groove. This effectively improves the applicability of the splash box and makes the splash box adaptable to different socket types.

[0006] Optionally, the extension direction of the through groove is the same as the length direction of the lug root.

[0007] According to the above technical solution, when the lug breaks, it can break along the length direction of the lug root, effectively preventing irregular breaks such as oblique breaks and improving the reliability of lug removal.

[0008] Optionally, the length of the through groove accounts for 60%-80% of the length of the lug root.

[0009] According to the above technical solution, the lugs can be guaranteed to have sufficient connection strength during normal installation, while being easy to operate when they need to be broken or pried off, effectively balancing the connection strength and removability of the lugs.

[0010] Optionally, the through groove is a rectangular groove with a width of 0.5mm-3mm.

[0011] According to the above technical solution, the connection strength of the lug is guaranteed, thereby reducing the risk of accidental breakage, and at the same time, it is convenient for tools to be inserted into the through groove to remove the lug.

[0012] Optionally, there are at least two through holes, which are symmetrically distributed at both ends of the through groove.

[0013] According to the above technical solution, by setting through holes, weak points are formed at both ends of the through groove, which facilitates the complete removal of the lug.

[0014] Optionally, the center distance of the through hole is 1mm-5mm from the edge of the root of the adjacent lug.

[0015] According to the above technical solution, the connection between the root of the lug and the inner wall of the mounting groove at the position between the through hole and the edge of the lug root is guaranteed. While ensuring the connection strength of the lug and preventing accidental breakage of the lug, it is easier to break or remove the lug.

[0016] Optionally, the center distance between the through hole and the end of the through groove is 1mm-5mm.

[0017] According to the above technical solution, the connection between the root of the lug and the inner wall of the mounting groove at the position between the through hole and the end of the through groove is guaranteed. While ensuring the connection strength of the lug and preventing accidental breakage of the lug, it is easier to break or remove the lug.

[0018] Optionally, the through hole can be a circular hole or a square hole.

[0019] Optionally, there are two lugs, symmetrically arranged on the inner wall of the mounting groove, and the top of the lugs is provided with positioning holes. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0025] refer to Figure 1 A splash guard 100 according to this embodiment includes a mounting base 20 and a cover 10 movably disposed on the mounting base 20. Specifically, the cover 10 is provided with a hinge portion 11, and the mounting base 20 is provided with a hinge engagement portion 21 corresponding to the hinge portion. Through the engagement connection between the hinge portion 11 and the hinge engagement portion 21, the cover 10 can be rotatably connected to the mounting base 20.

[0026] In this embodiment, the hinge portion 11 can be configured as a rotating rod, and the hinge mating portion 21 can be configured as a rotating groove into which the rotating rod is inserted. The cover 10 rotates by rotating the rotating rod in the rotating groove. It is understood that the hinge portion 11 and the hinge mating portion 21 can also be configured as other mating structures, as long as the cover 10 can be rotatably covered on the mounting base 20. The structure of the hinge portion 11 and the hinge mating portion 20 is not specifically limited.

[0027] Furthermore, the mounting base 20 can be connected to a socket and a back box, and the socket can be housed in the cavity of the mounting base 20. By flipping the cover 10, it can be placed over the mounting base 20 to cover the socket, thereby providing protection. In addition, the cover 10 is also provided with a cable passage 12, which can provide a channel for the power cord. When the cover 10 is placed over the mounting base 20, the power cord can extend from the inside of the splash-proof box to the outside through the cable passage 12, while maintaining the protective performance of the splash-proof box.

[0028] refer to Figure 1 and Figure 2 The mounting base 20 has a through mounting groove 22, and the inner side wall of the mounting groove 22 has a lug 23 for positioning and installation.

[0029] There are two lugs 23, which are symmetrically arranged on the inner side wall of the mounting groove 22. The top of the lug 23 is provided with a positioning hole 24, which can correspond to the screw holes on the socket and the bottom box, so as to facilitate the insertion of the mounting screw for positioning and installation.

[0030] Further, refer to Figure 3 The lug 23 has a through groove 231 in the middle and through holes 232 at the two ends of the through groove 231 at the connection position between the root of the lug 23 and the inner side wall.

[0031] In this embodiment, the through groove 231 and the through hole 232 can cooperate to form a breakable structure. When the socket has a rib that interferes with the lug 23, the lug 23 can be broken off directly based on the breakable structure, or the lug 23 can be pried off by inserting a screwdriver or other tool into the through groove 231. This effectively improves the applicability of the splash-proof box and makes it compatible with different socket types.

[0032] Furthermore, the through groove 231 forms a main fracture groove in the middle, and the through holes 232 are spaced at both ends of the through groove 231 to form corresponding weak points. When removing the lug 23, the lug 23 is guided to fracture along both sides of the weak points. The through groove 231 and through holes 232 can form a continuous fracture path, making the lug 23 fracture more smoothly and efficiently.

[0033] The extension direction of the through groove 231 is the same as the length direction of the root of the lug 23, so that when the lug 23 breaks, it can break along the length direction of the root of the lug 23, which can effectively prevent irregular fractures such as oblique fractures and improve the reliability of lug 23 removal.

[0034] The length of the through groove 231 accounts for 60%-80% of the length of the root of the lug 23.

[0035] Specifically, the through groove 231 is located in the middle of the connection between the root of the lug 23 and the inner wall of the mounting groove 22 to form the main fracture groove. When the length of the through groove 231 is too short, there will be more of a connection between the root of the lug 23 and the inner wall of the mounting groove 22, requiring more external force to break or pry off the lug 23, which can easily lead to difficulty in removing the lug 23. When the length of the through groove 231 is too long, there will be less of a connection between the root of the lug 23 and the inner wall of the mounting groove 22, which can easily make the connection of the lug 23 unstable, and may lead to the lug 23 breaking unexpectedly during the installation process.

[0036] In this embodiment, by setting the length of the through groove 231 to 60%-80% of the root length of the lug 23, it is possible to effectively ensure that the lug 23 has sufficient connection strength during normal installation, while being easy to operate when it needs to be broken or pried off, thus effectively balancing the connection strength and removability of the lug 23.

[0037] The through groove 231 is a rectangular groove with a width of 0.5mm-3mm. The width design of the through groove 231 can ensure the connection strength of the lug 23, reduce the risk of accidental breakage, and facilitate the insertion of tools into the through groove 231 to remove the lug.

[0038] There are at least two through holes 232, which are symmetrically distributed on the outer sides of both ends of the through groove 231, and the through holes 232 are arc-shaped or square holes. In this embodiment, the locations where the through holes 232 are set form corresponding weak points. By symmetrically arranging the through holes 232 on the outer sides of both ends of the through groove 231 and correspondingly close to the two ends of the root of the lug 23, when the lug 23 is removed, the two sides of the through holes 232 can serve as the fracture starting points, so that the root of the lug 23 is disconnected from the inner wall of the mounting groove 22, which facilitates the complete removal of the lug 23.

[0039] Understandably, while ensuring the connection strength of the lug 23, the number of through holes 232 can be increased to facilitate the complete removal of the lug 23.

[0040] The center distance of the through hole 232 is 1mm-5mm from the root edge of the lug 23, and the center distance of the through hole 232 is 1mm-5mm from the end of the through groove 231.

[0041] Specifically, the through hole 232 forms a weak point. The through hole 232 ensures that the root of the lug 23 is connected to the inner wall of the mounting groove 22 only on both sides of the through hole 232; that is, a connection is maintained between the through hole 232 and the edge of the lug 23's root, and between the through hole 232 and the through groove 231. When removing the lug 23, it can be guided to break along both sides of the weak point, facilitating the removal of the lug 23. In this embodiment, by controlling the connection range on both sides of the through hole 232, the connection strength of the lug 23 can be guaranteed, preventing accidental breakage of the lug 23, while making it easier to break or pry off the lug 23.

[0042] In summary, the splashproof box 100 in this embodiment, through the cooperation of the through groove 231 and the through hole 232, facilitates the removal of the lug 23, thereby improving its applicability.

[0043] Furthermore, after the lug 23 is broken or pried off by the cooperation of the through groove 231 and the through hole 232, some root burrs may be generated at the fracture location, which may still cause some interference to the socket rib.

[0044] To further address the aforementioned issues, in some embodiments, the fractured structure formed by the through groove 231 and through hole 232 between the lug 23 and the inner wall of the mounting groove 22 is replaced with a detachable structure. This allows the lug 23 to be detachably mounted on the inner wall of the mounting groove 22, ensuring that the lug 23 can be removed while preventing breakage and burr formation, thus guaranteeing the smoothness of the inner wall of the mounting groove 22 after the lug 23 is removed. Furthermore, when installing or replacing the socket, the lug 23 can be installed or removed depending on whether the socket has a rib, further increasing the applicability of the splash-proof box.

[0045] Specifically, in some embodiments, the lug 23 can be detachably disposed on the inner sidewall of the mounting groove 22 by means of a snap-fit ​​connection or a threaded connection, as follows:

[0046] Threaded connection: A threaded hole is provided in the inner wall of the mounting groove 22, and an external threaded screw that mates with the threaded hole is provided at the root of the lug 23. The lug 23 can be detachably connected to the mounting groove 22 by means of threaded connection. Operators can quickly and conveniently install or remove the lug 23 by directly screwing it on, without the need to add too many components, resulting in low production costs.

[0047] Snap-fit ​​connection: A snap-fit ​​groove is provided in the inner wall of the mounting groove 22. The snap-fit ​​groove has an opening on the inner wall of the mounting groove 22 and a groove body provided inside the inner wall of the mounting groove 22. The length of the groove body is longer than the length of the opening, and the portions of the groove body that are longer than the opening at both ends form corresponding limiting parts.

[0048] The shape and size of the root of the lug 23 are matched with the opening of the slot, and the two ends of the root of the lug 23 are provided with engaging parts corresponding to the limiting part. The engaging part is set as an arc-shaped part connected to the outside of the root of the lug 23. The arc-shaped part is made of a flexible plastic or other deformable material. The arc-shaped part has an arc-shaped surface corresponding to the edge of the slot opening. The arc-shaped surface provides a guide slope for sliding into the slot and an unlocking slope for sliding out of the slot.

[0049] When installing the lug 23, force can be applied to press the guide slope of the arc-shaped surface to contact the edge of the opening and deform under force, thereby pressing the engaging part through the opening into the limiting part; when removing the lug 23, force can be applied to pull it out, causing the unlocking slope of the arc-shaped surface to contact the edge of the opening and deform under force, thereby pulling the engaging part away from the limiting part, thus removing the lug 23.

[0050] Meanwhile, the depth of the slot is slightly higher than the height of the engaging part to ensure that the engaging part can be fully engaged with the limiting part after sliding into the slot, and to fix and limit the engaging part accordingly, ensuring the stability of the lug 23. In addition, the edges of the two ends of the opening can be set as bevels to facilitate the engagement with the arc surface of the arc-shaped part when the lug 23 is under force, assisting the lug 23 in sliding in and fixing or pulling out and disengaging.

[0051] With the above-mentioned snap-fit ​​connection structure, operators can quickly and easily install or remove the lug 23 by directly pressing or pulling it out, without the need to add too many components, resulting in low production costs.

[0052] Understandably, the above-described engaging and slotted connection method is an example of a snap-fit ​​connection. The engaging part can also be configured with other deformable structures to insert into / disengage from the limiting part. For example, the engaging part can be equipped with claws that can retract to both ends of the lug root. A miniature spring is provided inside the lug to connect with and hold the claws to keep them exposed. A movable button is provided on the side of the lug, which is on the same plane as the lug. The movable button is connected to the miniature spring. By pressing the movable button, the miniature spring can be compressed to retract the claws. At this time, the lug root can be inserted into the slot through the slot opening. After releasing the movable button, the miniature spring returns to its original shape, exposing the claws and placing them in the limiting part of the slot to complete the lug installation. At the same time, when removing the lug, pressing the movable button will retract the lug, releasing the limiting part and allowing the lug to be pulled out.

[0053] Furthermore, with the above-mentioned lug 23 being detachably disposed on the inner side wall of the mounting groove 22, the cover 10 of the splash box 100 can also be provided with an openable and closable mounting box. Without affecting the protective performance of the splash box, it can provide storage space for storing the disassembled lug 23, which facilitates the storage of the disassembled lug 23 and the retrieval of the lug 23 when needed.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
