Description

Technical Field

[0001] This application relates to the field of distribution boxes, and more particularly to a distribution box housing suitable for installation in multiple scenarios. Background Technology

[0002] Currently, distribution boxes, as basic equipment in electrical systems used to install switches, circuit breakers, protective devices, and terminals, are widely used in residential, commercial buildings, industrial plants, and public facilities. With the diversification of building structures, decoration requirements, and on-site installation conditions, distribution boxes not only need to meet the needs of electrical component installation and wiring protection, but also need to adapt to different spatial locations, wall structures, and overall aesthetic requirements.

[0003] In existing technologies, distribution box enclosures are typically designed specifically for different installation scenarios, such as surface-mounted wall-mounted enclosures, floor-standing enclosures, or recessed wall-mounted enclosures. While these enclosures offer advantages such as simple structure and clear installation methods for specific installation applications, their installation structure usually corresponds to a single usage scenario. Therefore, when the distribution box is applied to different building structures or different interior design environments, it is often necessary to select a different type of enclosure or adapt it using additional brackets, embedded structures, components, or other accessories.

[0004] However, in existing technologies, distribution boxes typically correspond to different housing structures or installation accessories in different installation scenarios. The installation methods of distribution boxes usually include surface mounting and concealed mounting. Surface mounting includes wall mounting and floor mounting. Furthermore, when surface mounting is used in outdoor scenarios, a rainproof structure is also required. This means that distribution boxes need to be replaced with different housings or configured with different components for different installation scenarios, resulting in poor adaptability of the distribution box housing in different installation scenarios. Therefore, there is an urgent need for a distribution box housing that is suitable for installation in multiple scenarios. Summary of the Invention

[0005] To improve the adaptability of distribution boxes in different installation scenarios, this application provides a distribution box housing suitable for installation in multiple scenarios.

[0006] The technical solution provided in this application for a distribution box housing suitable for installation in multiple scenarios is as follows: A distribution box housing suitable for installation in multiple scenarios includes a box body and a first support frame, a second support frame, and a third support frame disposed on the box body. The first support frame is rotatably connected to the box body and can be in an open state and a closed state on the box body. The second support frame is slidably connected to the box body and can be in an extended state and a retracted state on the box body. The third support frame can be installed on the top of the box body through a third fixing structure or on the side of the box body through a second fixing structure. The first support frame in the open state and the second support frame in the extended state can form the base of the box, and the first support frame in the closed state and the second support frame in the retracted state can form the support of the box. The third support frame located on the top of the box can form a rain shelter structure for the box, and the third support frame located on the side of the box and the first support frame in the closed state can be spliced ​​together to form an embedded frame for the wall.

[0007] By adopting the above technical solutions, in outdoor surface-mounted scenarios, the third support frame, positioned on top of the enclosure, forms a rain-shielding structure to protect against rain. In indoor surface-mounted floor-standing scenarios, the first support frame, which rotates and opens along the enclosure, cooperates with the second support frame, which slides and extends along the enclosure, to form a base supporting the enclosure. In indoor surface-mounted wall-mounted scenarios, the second support frame slides and retracts along the enclosure, and the first support frame, which rotates and closes, is fixed to the wall, forming a bracket to support the enclosure. In concealed scenarios, the third support frame can be detached from the top of the enclosure and connected to the side of the enclosure. The third support frame on the side of the enclosure can cooperate with the first support frame, which rotates and closes, to form an embedded frame within the wall. This application employs a scheme where the positions of the first, second, and third support frames relative to the enclosure are adjustable. As components on the enclosure, the first, second, and third support frames can adapt to different installation scenarios such as floor-standing, wall-mounted, surface-mounted, and concealed installations. Each component can be used in at least two installation scenarios, improving the adaptability of the distribution box enclosure in different installation scenarios.

[0008] Preferably, the first support frame is provided with an extension bracket, which is slidably connected to the first support frame and can be fixedly connected to the first support frame by a fastener.

[0009] By adopting the above technical solution, the support height of the first support frame when forming a base in an exposed floor installation scenario can be extended by sliding the extended bracket relative to the first support frame. This allows the enclosure to adapt to different floor installation scenarios with varying height requirements, improving the adjustability of the first support frame in floor installation scenarios.

[0010] Preferably, the fastener includes a first bolt, the first support frame is provided with a plurality of first insertion holes, the extension bracket is provided with a second insertion hole along the extension direction of the extension bracket, and the first bolt can be inserted into the second insertion hole and the first insertion holes at different positions to fix the extension bracket on the first support frame.

[0011] By adopting the above technical solution, the extension bracket can be fixed at different extension positions of the first support frame by inserting the first bolt through the first and second insertion holes at different positions. This ensures that the extension bracket remains fixed after the extension length adjustment is completed, preventing the extension bracket from sliding relative to the first support frame and improving the stability of the extension bracket.

[0012] Preferably, the second support frame in the extended state can form a support for the housing together with the extension bracket fixed to the first support frame.

[0013] By adopting the above technical solution, the second support frame in the extended state cooperates with the extension bracket fixed on the first support frame to form multi-point support for the box in the landing scenario, thereby improving the stability of the box installation.

[0014] Preferably, the extension bracket has a first fixing plate on the side away from the first support frame, and the first fixing plate has a first fixing hole for the insertion of an expansion bolt. The expansion bolt can fix the first support frame in the closed state to the wall through the first fixing hole.

[0015] By adopting the above technical solution, expansion bolts are used to pass through the first fixing hole on the first fixing plate and the drilled hole on the wall in sequence to fix the first support frame in the closed state to the wall. This allows the first support frame to stably support the box in the surface-mounted wall-mounted scenario, preventing the box from loosening after wall-mounting and improving the firmness of the wall-mounted installation.

[0016] Preferably, the third support frame includes two plates, each plate having a wing plate at one end. The angle between the wing plate and the corresponding plate is an acute angle α. The two wing plates are fitted and fixedly connected. The angle formed by each wing plate and the corresponding plate faces the top of the box. The end of each plate away from the wing plate is fixedly connected to the box through the third fixing structure, so that the two plates can form a rainproof structure that guides rainwater to the sides of the box.

[0017] By adopting the above technical solution, the wing plate set at an angle α with the plate can connect two symmetrically inclined plates, so that the two plates can form an arched rainproof structure on the top of the box and guide rainwater to flow along the two plates to the two sides of the box respectively, thereby improving the rainproof reliability of the box when it is installed outdoors.

[0018] Preferably, the second fixing structure includes two insertion slots, which are respectively disposed on both sides of the box body. The insertion slots correspond one-to-one with the wing plates on the plate body, and the included angle between the wing plates and the corresponding side of the box body is an acute angle α. The wing plates can be inserted into the corresponding insertion slots, so that the plate body and the side of the box body are parallel to each other.

[0019] By adopting the above technical solution, the angle between the insertion slot and the corresponding side of the box body is adapted to the angle between the wing plate and the plate body. After the wing plate is inserted into the corresponding insertion slot, the plate body can be parallel to the side of the box body, so that the two plates can form a support structure on both sides of the box body in the concealed installation scenario, and cooperate with the wall groove to position the box body, thereby improving the stability of the concealed installation of the box body.

[0020] Preferably, the depth of each insertion slot along the insertion direction of the wing plate is less than the length of the wing plate, so that a cable space for placing cables is formed between the plate and the side of the box.

[0021] By adopting the above technical solution, the depth of the insertion slot along the insertion direction of the wing plate is less than the length of the wing plate. After the wing plate is inserted into the insertion slot, a gap space can be maintained between the side of the plate and the box, so that the cable in the concealed installation scenario can be placed between the side of the plate and the box, which improves the convenience of cable arrangement when the box is concealed.

[0022] Preferably, the end of each plate away from the wing plate can be fixedly connected to the first support frame by a fifth bolt, so as to be spliced ​​with the first support frame to form an embedded frame in the wall.

[0023] By adopting the above technical solution, the end of each plate away from the wing plate is fixedly connected to the first support frame by bolts. The two plates and the first support frame are spliced ​​together to form a U-shaped embedded frame structure in the wall, so that the box can be embedded in the wall groove through the U-shaped embedded frame in the concealed installation scenario, which improves the adaptability of the concealed installation structure of the box.

[0024] Preferably, an elastic element is provided between the two wing plates, which can form a seal at the connection between the two wing plates.

[0025] By adopting the above technical solution, the elastic element is set between the two wing plates, which can form an elastic seal at the connection between the two wing plates, preventing rainwater from seeping into the box through the connection between the wing plates, and improving the sealing reliability when the third support frame is used as a rain shelter structure.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. In outdoor surface-mounted scenarios, the third support frame, positioned on top of the enclosure, forms a rain-shielding structure to protect against rain. In indoor surface-mounted floor-standing scenarios, the first support frame, which rotates and opens along the enclosure, cooperates with the second support frame, which slides and extends along the enclosure, to form a base supporting the enclosure. In indoor surface-mounted wall-mounted scenarios, the first support frame, which rotates and closes, can be fixed to the wall, forming a bracket to support the enclosure. In concealed scenarios, the third support frame can be detached from the top of the enclosure and connected to the side of the enclosure. The third support frame on the side of the enclosure can cooperate with the first support frame, which rotates and closes, to form an embedded frame within the wall. The first, second, and third support frames, as components on the enclosure, can adapt to different installation scenarios such as floor-standing, wall-mounted, surface-mounted, and concealed installations. Each component can be used in at least two installation scenarios, improving the adaptability of the distribution box enclosure in different installation scenarios. 2. By utilizing the sliding of the extension bracket relative to the first support frame, the support height of the first support frame when forming a base in an exposed floor-mounted scenario can be extended, allowing the enclosure to adapt to floor-mounted scenarios with different height requirements and improving the adjustment flexibility of the first support frame in floor-mounted scenarios. 3. By using the wing plate set at an angle α with the plate body, two symmetrically inclined plates can be connected, so that the two plates can form an arched rainproof structure on the top of the box body, and guide rainwater to flow along the two plates to the two sides of the box body respectively, which improves the rainproof reliability of the box body when it is installed outdoors.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0038] This application discloses a distribution box housing suitable for installation in multiple scenarios.

[0039] Reference Figure 1 and Figure 2 A distribution box housing suitable for installation in multiple scenarios includes a box body 1 and a first support frame 2, a second support frame 4, and a third support frame 5 disposed on the box body 1. A door 11 is rotatably provided on the front of the box body 1. The first support frame 2 is hinged to the box body 1, with the hinge point located below the door 11, and can rotate towards the back of the box body 1, allowing the first support frame 2 to be in an open or closed state on the box body 1. The second support frame 4 is disposed on the back of the box body 1 and slidably connected to the box body 1, allowing the second support frame 4 to be in an extended or retracted state on the box body 1. The third support frame 5 can be installed on the top of the box body 1 via a third fixing structure 52, or on the side of the box body 1 via a second fixing structure 13.

[0040] Reference Figure 1 and Figure 2 In the case of surface-mounted installation, the first support frame 2 in the open state and the second support frame 4 in the extended state can form the base of the box 1.

[0041] Reference Figure 3 , Figure 4 and Figure 5In the case of surface-mounted wall installation, the first support frame 2 in the closed state and the second support frame 4 in the retracted state can form a support for the box 1.

[0042] Reference Figure 1 and Figure 3 In outdoor installation scenarios, the third support frame 5 installed on the top of the box 1 can form a rainproof structure for the box 1.

[0043] Reference Figure 6 , Figure 7 and Figure 8 In a concealed installation scenario, the third support frame 5 installed on the side of the enclosure 1 can be joined with the first support frame 2 in a closed state to form an embedded frame for the wall. Through this configuration, the first support frame 2, the second support frame 4, and the third support frame 5 can adapt to different installation scenarios such as floor-mounted, wall-mounted, surface-mounted, and concealed installations. Furthermore, each support component can be used for at least two installation scenarios, improving the adaptability of the distribution box enclosure in different installation environments.

[0044] Reference Figure 1 , Figure 2 and Figure 3 The first support frame 2 includes two support columns 21, each with a square hollow structure. The two support columns 21 are arranged parallel to each other and are respectively located at two corners of the bottom of the box 1 away from the back. Both support columns 21 are hinged to the bottom of the box 1. The bottom of the box 1 is provided with two limiting plates 24, which are respectively located on the side of the hinge point between the corresponding support column 21 and the bottom of the box 1. The limiting plates 24 can limit the maximum deflection angle of the corresponding support column 21 relative to the bottom of the box 1 to 90°. In the open state, both support columns 21 are perpendicular to the bottom of the box 1; in the closed state, both support columns 21 are attached to the bottom of the box 1 and are arranged parallel to each other, with the end of each support column 21 away from the hinge point flush with the back of the box 1.

[0045] An extension bracket 3 is slidably mounted on the first support frame 2. The extension bracket 3 is fixedly connected to the first support frame 2 via a fixing member 23. The extension bracket 3 includes two extension columns 31, which correspond one-to-one with the support columns 21. The extension columns 31 are square hollow structures, and their cross-sectional areas are smaller than those of the support columns 21, allowing the extension columns 31 to be inserted into their corresponding support columns 21 and to slide and extend along them. Each support column 21 has multiple first insertion holes 22 on both sides, spaced apart along the length of the support column 21. The extension column 31 has a second insertion hole, through which the fixing member 23 passes sequentially to the first insertion holes 22 and the second insertion hole, thus fixing the extension column 31 to the corresponding support column 21. In this embodiment, the fastener 23 is the first bolt 231. The first bolt 231 can be inserted from the first insertion hole 22 on one side of the support column 21, pass through the second insertion hole of the extension column 31, and exit from the first insertion hole 22 on the other side of the support column 21. It is then locked and fixed by a nut to prevent the extension column 31 from sliding relative to the support column 21.

[0046] Each extension column 31 has a first fixing plate 33 fixed at its end away from the support column 21. The first fixing plate 33 is a rectangular plate structure with a first fixing hole 34 through it, which is used for expansion bolts to pass through. In a surface-mounted installation scenario, the first fixing plate 33 can rest against the ground, and the expansion bolts can pass through the first fixing hole 34 and be inserted into pre-drilled holes in the ground. After the expansion bolts tighten, they can fix the first fixing plate 33 to the ground.

[0047] Reference Figure 4 , Figure 5 and Figure 6The second support frame 4 includes two sliding rods 41, each with a concave cross-section, and the two sliding rods 41 are arranged parallel to each other. The back of the housing 1 is provided with two slide rails 42, each with a convex cross-section. The sliding rods 41 correspond one-to-one with the slide rails 42 and are slidably connected to the corresponding slide rails 42, allowing the sliding rods 41 to slide out from the bottom of the housing 1. The back of the housing 1 is provided with two sliding grooves 43, each corresponding one-to-one with the slide rails 42. The sliding rods 41 are slidably disposed within the sliding grooves 43, allowing the second support frame 4 to be stored in the back of the housing 1. The sliding rods 41 are offset from the support column 21 on the back of the housing 1, making it less likely that the extended column 31 extending from the support column 21 in the closed state will interfere with the extended column 31 when the sliding rod 41 is extended. The sliding rod 41 is provided with a plurality of second connecting holes 411 spaced apart, and the slide rail 42 is provided with a plurality of second threaded holes 421 spaced apart. The second bolt 422 can pass through the second connecting holes 411 and be threadedly connected to the second threaded holes 421, so that the sliding rod 41 can be fixed on the slide rail 42. Each sliding rod 41 is provided with a second fixing plate 44 at one end near the bottom of the housing 1. The second fixing plate 44 is provided with a second fixing hole for the expansion bolt to pass through, so that the sliding rod 41 extending to the ground can be fixedly connected to the ground through the second fixing plate 44.

[0048] Reference Figure 1 and Figure 5 The sliding rod 41 extends to a distance not less than the maximum length formed by the extension column 31 and the support column 21, so that the two sliding rods 41 in the extended state can together with the two extension columns 31 fixed on the support column 21 to form a four-point support for the housing 1. Note that the multiple second threaded holes 421 match the positions where the sliding rods 41 are fixed to the extension columns 31 on the support column 21.

[0049] Specifically, in the case of surface-mounted floor installation, the support column 21 is rotated to a position perpendicular to the bottom of the housing 1, so that the support column 21 is in an open state; the extension length of the extension column 31 on the corresponding support column 21 is adjusted according to the installation height requirements, and the extension column 31 is fixed to the support column 21 by the first bolt 231; then the two sliding rods 41 are slid out from the back of the housing 1 to a position flush with the end of the extension column 31 away from the support column 21, and the sliding rods 41 are fixed to the slide rail 42 by the second bolt 422, so that the two extension columns 31 and the two sliding rods 41 can form a four-point support base, thereby enabling the housing 1 to adapt to floor installation scenarios with different height requirements.

[0050] Reference Figure 3 , Figure 4 and Figure 5In a surface-mounted wall-mounted installation scenario, the support column 21 is rotated back to a position flush with the bottom of the housing 1, thus closing the support column 21. The extension length of the extension column 31 on the support column 21 is then adjusted according to the installation distance between the housing 1 and the wall. The extension column 31 is then fixed to the support column 21 using the first bolt 231. The first fixing plates 33 on the two extension columns 31 can respectively abut against the wall. Expansion bolts can pass through the first fixing holes 34 on the first fixing plates 33 and be inserted into pre-drilled holes in the wall. After the expansion bolts tighten, the first fixing plates 33 are fixed to the wall, thus allowing the two support columns 21, in their closed state, to support the housing 1. At this time, the second support frame 4 is retracted and stored in the sliding groove 43 on the back of the housing 1, reducing interference of the second support frame 4 with the wall-mounted installation of the housing 1.

[0051] Reference Figure 5 The third support frame 5 includes two plates 51, both of which are rectangular plate structures. Each plate 51 has a wing plate 55 at one end, and the included angle between the wing plate 55 and the corresponding plate 51 is an acute angle α. The two wing plates 55 are fitted together, and an elastic element 56 is sandwiched between them. The elastic element 56 can be a rubber sealing strip and extends along the length of the wing plate 55. Each wing plate 55 has a fourth connecting hole, and a fourth bolt 551 can pass through the fourth connecting hole on the two wing plates 55 and the elastic element 56 in sequence, and be locked in place by a nut, so that the two plates 51 can be connected by the two wing plates 55 to form the third support frame 5.

[0052] In outdoor installation scenarios, the third support frame 5 is installed on the top of the housing 1, forming a rain shelter structure for the housing 1. The angle formed by each wing plate 55 and its corresponding plate 51 points towards the top of the housing 1. Since both wing plates 55 are vertically positioned, the two plates 51 extend at an angle towards the front and rear sides of the housing 1, respectively. The end of each plate 51 furthest from the wing plate 55 is fixedly connected to the housing 1 via a third fixing structure 52. The third fixing structure 52 includes a third bolt 521, a third connecting hole on the plate 51, and a third threaded hole on the top of the housing 1. The third bolt 521 passes through the third connecting hole and is threadedly connected to the third threaded hole, thereby fixing the two plates 51 to the two sides of the top of the housing 1. In outdoor surface-mounted scenarios, the third support frame 5 composed of the two plates 51 forms a rain shelter structure. Rainwater falling on the two plates 51 flows along the two plates 51 towards the front and rear sides of the housing 1 and is discharged.

[0053] Reference Figure 7 , Figure 8 and Figure 9In a concealed installation scenario, the third bolt 521 and the fourth bolt 551 can be removed sequentially to separate the two plates 51, which can then be installed on the left and right sides of the housing 1 respectively. An embedding space 12 is pre-drilled in the wall, the size of which is larger than the size of the housing 1, allowing the housing 1 to be embedded in the wall. A second fixing structure 13 is provided on both sides of the housing 1, comprising two insertion slots 14 located on the left and right sides of the housing 1, near the top of the housing 1. The angle between each insertion slot 14 and the corresponding side of the housing 1 is an acute angle α. When the wing plate 55 on the plate 51 is inserted into the corresponding insertion slot 14, the angle between the insertion slot 14 and the corresponding side of the housing 1 matches the angle between the wing plate 55 and the corresponding plate 51, causing the side of the corresponding plate 51 furthest from the wing plate 55 to face the bottom of the housing 1 and be parallel to the side of the housing 1.

[0054] Reference Figure 4 , Figure 7 and Figure 9 Each insertion slot 14 has a depth less than the length of the wing plate 55 along the insertion direction of the wing plate 55, so that after the wing plate 55 is inserted into the insertion slot 14, a cable space 15 can be formed between the plate body 51 and the side of the housing 1. The cable space 15 can be used to place cables in a concealed installation scenario. In a concealed embedded installation scenario, the support column 21 is attached to the bottom of the housing 1, and the extension column 31 can retract into the corresponding support column 21. When the wing plate 55 is inserted into the insertion slot 14, the side of the plate body 51 away from the wing plate 55 extends to the side of the support column 21. The side of the plate body 51 away from the wing plate 55 is provided with a fifth connecting hole 54, which is opposite to the first insertion hole 22. The second insertion hole on the extension column 31 can be opposite to the first insertion hole 22. The fifth bolt 541 can pass through the fifth connecting hole 54, the first insertion hole 22 and the second insertion hole in sequence, and be locked and fixed by the nut, so that the plates 51 on both sides of the box 1 can be connected to the support column 21 at the bottom of the box 1, thereby forming an embedded frame embedded in the wall. The embedded frame can position the embedded position of the box 1 and provide a fixed foundation for the box 1, avoiding the problems of installation position displacement, damage to the edge of the wall hole or unstable fixation caused by the box 1 being directly installed in the wall hole, thus improving the installation stability of the distribution box in the concealed state.

[0055] The implementation principle of a distribution box housing applicable to multiple installation scenarios according to an embodiment of this application is as follows: In the surface-mounted installation scenario, the two sets of support columns 21 are rotated to the open state, and the extension length of the two sets of extension columns 31 relative to the corresponding support columns 21 is adjusted according to the installation height. Then, the two sets of sliding rods 41 are slid out from the back of the box 1, so that the two sets of extension columns 31 and the two sets of sliding rods 41 together form a ground support for the box 1; In the surface-mounted wall-mounted installation scenario, the two sets of support columns 21 are rotated to the closed state, and the extension length of the two sets of extension columns 31 relative to the corresponding support columns 21 is adjusted according to the distance between the box 1 and the wall, so that the two sets of extension columns 31 can form a wall-mounted support for the box 1, and the two sets of sliding rods 41 remain in the retracted state; In the outdoor installation scenario, Two symmetrically arranged plates 51 are installed on the top of the enclosure 1, allowing rainwater to drain along the two plates 51 to the front and rear sides of the enclosure 1, thus providing rain protection for the enclosure 1. In the case of concealed installation, the two symmetrically arranged plates 51 are disassembled and installed on the left and right sides of the enclosure 1 respectively, and the two plates 51 are connected to the two sets of support columns 21 in a closed state. The two plates 51 and the two sets of support columns 21 can form an embedded frame together. The support columns 21, extension columns 31, sliding rods 41 and plates 51, as components on the enclosure 1, can adapt to different installation scenarios such as floor mounting, wall mounting, surface mounting and concealed mounting. Each component can be used in at least two installation scenarios, improving the adaptability of the distribution box enclosure in different installation scenarios.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
