[0046] The following is combined with Figures 1 to 12 A wire box is described according to an embodiment of the present disclosure.

[0047] In embodiments of this disclosure, such as Figures 1 to 5As shown, the electrical box provided in the embodiments of this disclosure includes a box body 10 and a movable member 20. The box body 10 is embedded in the wall 40 and has a receiving groove 110 and a through hole 130 communicating with the receiving groove 110. The movable member 20 is movably connected to the box body 10 and has a through groove 210 communicating with the receiving groove 110. The movable member 20 is used to connect with a target object 30. A limiting structure is provided between the movable member 20 and the box body 10. The movable member 20 can move in a direction parallel to the central axis of the box body 10. The limiting structure is used to fix the movable member 20 at the target position of the box body 10 so that the distance between the mounting surface 220 of the movable member 20 and the wall surface 41 of the wall 40 meets the target distance.

[0048] The shape of the box 10 is not specifically limited; the box 10 can be a square box, a polygonal box, a circular box, etc.

[0049] In some embodiments, the box body 10 can be a square box body, having a length direction, a width direction, and a height direction. Along the height direction, the box body 10 has two opposing surfaces, defined as a top surface 120 and a bottom surface. The box body 10 is provided with a receiving groove 110, the cross-section of which can be square, circular, etc. The receiving groove 110 communicates with the top surface 120. The box body 10 is also provided with a through hole 130, which communicates with the receiving groove 110. The diameter of the through hole 130 is adapted to the diameter of the electrical conduit, which includes a polyvinyl chloride (PVC) electrical conduit. The electrical conduit can pass through the through hole 130 and enter the receiving groove 110.

[0050] In some embodiments, the box body 10 can be a circular box body, and along the axial direction of the box body 10, the box body 10 has two opposing surfaces, defined as the top surface 120 and the bottom surface. The cross-section of the receiving groove 110 can be circular, the receiving groove 110 communicates with the top surface 120, and the through hole 130 communicates with the receiving groove 110, allowing the electrical conduit to pass through the through hole 130 and enter the receiving groove 110.

[0051] The movable component 20 can be T-shaped. It has a through groove 210 that penetrates two opposing surfaces, defined as a first end face and a second end face. At least a portion of the movable component 20 can extend into the receiving groove 110 of the housing 10, and the through groove 210 of the movable component 20 communicates with the receiving groove 110 of the housing 10. The movable component 20 is used to connect with a target object 30, which includes switches, sockets, etc. The target object 30 is described below using a switch as an example. The first end face is defined as the mounting surface 220, which is higher than the top surface 120 of the housing 10. The back of the switch can fit against the mounting surface 220 of the movable component 20.

[0052] A limiting structure is provided between the movable component 20 and the box body 10. The movable component 20 moves along the central axis of the box body 10 relative to its top surface 120 to the target position. The limiting structure restricts the movable component 20 to the target position, ensuring that the distance between the mounting surface 220 of the movable component 20 and the wall surface 41 meets the target distance. During the installation of the electrical box on the wall 40, the following situation may occur: due to installation errors, the distance between the top surface 120 of the box body 10 and the wall 41 may not meet the requirements. The movable component 20 can be adjusted to ensure that the distance between its mounting surface 220 and the wall 41 meets the target distance, ensuring the aesthetics of the installed box. When installing multiple electrical boxes, adjusting the movable component 20 ensures the consistency of the distance between the mounting surface 220 of the electrical box and the wall 41.

[0053] In some embodiments, such as Figure 7 and Figure 10 As shown, the limiting structure includes an internal thread 123 and an external thread 221 that are screwed together. The movable part 20 can be connected to the box 10 by screwing. As the movable part 20 is screwed in or out relative to the box 10, the distance between the mounting surface 220 of the movable part 20 and the top surface 120 of the box 10 is adjusted, thereby realizing the adjustment of the target distance between the mounting surface 220 of the movable part 20 and the wall 41.

[0054] In some embodiments, the limiting structure includes a meshing gear and a rack. A rack is provided on the groove wall of the receiving groove 110 of the housing 10, and a rotatable gear is provided on the outer surface of the movable member 20. The gear meshes with the rack. A pushing or pulling force is applied to the movable member 20, causing it to move towards the inside or outside of the housing 10. Once the movable member 20 is in position, the applied force is stopped, and the movable member 20 is fixed at the target position. This achieves the adjustment of the target distance between the mounting surface 220 of the movable member 20 and the wall surface 41.

[0055] In some embodiments, the limiting structure includes a positioning groove, a threaded hole, and a fastener. A long, narrow positioning groove is formed on the groove wall of the housing 10, extending from the bottom surface of the housing 10 to the top surface 120. The movable member 20 has a threaded hole, which is opposite to the positioning groove and passes through the through groove 210. The fastener includes a screw. After the movable member 20 moves into position relative to the housing 10, the screw is screwed into the threaded hole and abuts against the bottom surface of the positioning groove, thereby fixing the movable member 20 at the target position and adjusting the target distance between the mounting surface 220 of the movable member 20 and the wall surface 41.

[0056] The following describes the installation and position adjustment process of the electrical box.

[0057] First, a mounting groove matching the shape of the box 10 is cut into the wall 40. The box 10 is placed in the mounting groove, and expanding foam or mortar is sprayed between the box 10 and the groove wall to fix the box 10 in the wall 40. Then, the movable part 20 is aligned with the receiving groove 110 of the box 10, with at least a portion of the movable part 20 entering the receiving groove 110. The movable part 20 is moved until it is in place, and the distance between the mounting surface 220 of the movable part 20 and the wall 41 meets the target distance. The movable part 20 is then fixed at the target position of the box 10 by a limiting structure. After the movable part 20 is fixed, the electrical conduit laid in the wall 40 can enter the receiving groove 110 through the through hole 130 and further extend into the through groove 210 of the movable part 20. Then, the wires in the conduit are connected to the terminals in the switch, and the switch is then fixed to the mounting surface 220 of the movable part 20 with fasteners.

[0058] like Figure 4 As shown, the electrical box is installed on the wall 40 without the decorative panel 50. After the distance between the mounting surface 220 of the movable part 20 and the wall 41 meets the target distance, the switch is fixedly connected to the mounting surface 220 of the movable part 20. When multiple electrical boxes are installed on the wall 40, it can be ensured that the height of the mounting surface 220 of each electrical box relative to the wall 41 is consistent, ensuring the aesthetics after installation.

[0059] like Figure 5 As shown, the electrical box is installed on the wall 40 with a decorative panel 50. The decorative panel 50 has two opposing surfaces, defined as the front and back surfaces 51, respectively, and there is a certain distance between the decorative panel 50 and the wall 40. After the distance between the mounting surface 220 of the movable component 20 and the wall surface 41 meets the target distance, the decorative panel 50 is fixed to the wall 40. The distance between the back surface 51 of the decorative panel 50 and the wall 40 is the target distance. After the decorative panel 50 is fixed, the mounting surface 220 of the movable component 20 is in contact with the back surface 51 of the decorative panel 50. The next step is to fix the switch to the movable component 20. Adjusting the distance between the mounting surface 220 of the movable component 20 and the wall surface 41 before installing the decorative panel 50 facilitates subsequent installation work for the operators.

[0060] In the embodiments of this disclosure, the electrical box includes a box body 10 and a movable component 20. By moving the movable component 20, the distance between the mounting surface 220 of the movable component 20 and the top surface 120 of the box body 10 can be flexibly adjusted, thereby adjusting the distance between the mounting surface 220 and the wall surface 41. When the movable component is moved into place, the movable component 20 is fixed at the target position of the box body 10 by the limiting structure, thereby flexibly adjusting the position of the mounting surface 220 of the electrical box, which helps to improve the aesthetics of the installation.

[0061] In embodiments of this disclosure, such as Figures 6 to 12 As shown, the box body 10 includes a base plate 11 and a surrounding plate 12. The surrounding plate 12 is located on one side of the base plate 11, and the base plate 11 and the surrounding plate 12 together form a receiving groove 110. The movable part 20 includes a mounting plate 21 and a first connecting part 22. The mounting plate 21 is used to connect with the target object 30, and the first connecting part 22 is located on one side of the mounting plate 21. A through groove 210 passes through the mounting plate 21 and the first connecting part 22. The limiting structure includes an internal thread 123 and an external thread 221 that are screwed together. The inner wall surface of the surrounding plate 12 is provided with the internal thread 123, and the outer wall surface of the first connecting part 22 is provided with the external thread 221. The first connecting part 22 and the surrounding plate 12 are screwed together by the internal thread 123 and the external thread 221.

[0062] In some embodiments, such as Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, the box body 10 includes a square box body, and the surrounding plate 12 is square in shape. The bottom plate 11 and the surrounding plate 12 can be integrally formed by injection molding. The receiving groove 110 extends from the top surface 120 of the surrounding plate 12 to the bottom plate 11. It can be understood that, along the height direction of the box body 10, the cross-section of the receiving groove 110 near the top of the box body 10 is smaller than the cross-section of the receiving groove 110 near the bottom of the box body 10. An internal thread 123 is machined in the upper region of the inner wall surface of the surrounding plate 12. The length, pitch diameter, and other parameters of the internal thread 123 are set according to actual requirements.

[0063] like Figure 2 , Figure 3 , Figure 10 , Figure 11 and Figure 12 As shown, the movable part 20 can be T-shaped. The movable part 20 includes a mounting plate 21 and a first connecting part 22. The first connecting part 22 is located on one side of the mounting plate 21, and the cross-section of the mounting plate 21 is larger than the cross-section of the first connecting part 22. The mounting plate 21 can be a hollow square-shaped plate, and the first connecting part 22 can be a hollow column. An external thread 221 is provided on the outer wall of the first connecting part 22, and the external thread 221 is adapted to the internal thread 123, meaning that the external thread 221 and the internal thread 123 can be screwed together. It is understood that the through groove 210 penetrates both the mounting plate 21 and the first connecting part 22.

[0064] The following describes the installation process of the movable part 20 and the box body 10. Align the first connecting portion 22 of the movable part 20 with the receiving groove 110 of the box body 10. After the first connecting portion 22 enters the receiving groove 110, rotate the movable part 20. The first connecting portion 22 will continuously screw into the receiving groove 110 until the movable part 20 moves into place, at which point stop rotating the movable part 20. Once the movable part 20 is in place, it does not need to be fixed by other fasteners or connectors. This improves operational convenience while simplifying the structure of the electrical box, while still satisfying the adjustment function.

[0065] The first connecting part 22 can be fixed at any position on the internal thread 123 of the housing 10 according to the target distance requirement, and the position of the mounting surface 220 of the movable part 20 can be finely adjusted.

[0066] In the embodiments of this disclosure, the movable part 20 and the box body 10 are connected by screws. There is no need for other fasteners or fixing parts to connect them. The position of the movable part 20 can be adjusted by rotating the movable part 20, and the movable part 20 can be fixed by the screw structure. This not only facilitates operation and enables precise adjustment of the position of the movable part 20, but also simplifies the structure of the wire box.

[0067] In embodiments of this disclosure, such as Figure 7 , Figure 8 and Figure 9 As shown, the enclosure 12 includes a plurality of support portions connected end to end; the through hole 130 includes a first through hole 131, at least one first through hole 131 is provided in one of the plurality of support portions along a first direction, and at least one first through hole 131 is provided in one of the plurality of support portions along a second direction, the first direction and the second direction intersect.

[0068] In some embodiments, the box body 10 includes a square box body, and the surrounding plate 12 is square in shape. The surrounding plate 12 includes four support portions connected end to end, defined as a first support portion 121, a second support portion, a third support portion 122, and a fourth support portion. The first support portion 121 and the second support portion are arranged opposite each other along a first direction, and the third support portion 122 and the fourth support portion are arranged opposite each other along a second direction. At least one of the four support portions is provided with a first through hole 131.

[0069] For example, the first support portion 121 and the third support portion 122 are provided with a first through hole 131. The electrical conduit laid on the wall 40 can extend from the area opposite to the first support portion 121 to the first support portion 121, and further enter the receiving groove 110 through the first through hole 131; the electrical conduit can extend from the area opposite to the third support portion 122 to the second support portion, and further enter the receiving groove 110 through the first through hole 131.

[0070] For example, the first support 121, the second support, the third support 122, and the fourth support are all provided with a first through hole 131. Electrical conduits laid on the wall 40 can extend from the area opposite any of the four supports to the support, and further enter the receiving groove 110 through the first through hole 131. Each support is provided with a first through hole 131, and electrical conduits laid on the wall 40 can simultaneously enter the receiving groove 110 through the first through holes 131 on all four supports. For example, a switch has four buttons, each controlling a light source in a different location. Four electrical conduits can each enter the receiving groove 110 through the first through holes 131 on the four supports, meaning the receiving groove 110 can simultaneously accommodate four electrical conduits. The four electrical conduits extend into the through groove 210 of the movable member 20 and connect to the terminals on the switch. The provision of a first through hole 131 on each support facilitates flexibility in use.

[0071] In some embodiments, each support portion may be provided with one, two, or more first through holes 131, and the number of first through holes 131 is not specifically limited. The number of first through holes 131 provided on the four support portions may be the same or different. For example, the first support portion 121, the second support portion, the third support portion 122, and the fourth support portion are each provided with two first through holes 131.

[0072] In the embodiments of this disclosure, the enclosure 12 includes a plurality of support portions connected end to end, and each support portion can be provided with a first through hole 131. The axial direction of at least one first through hole 131 is parallel to a first direction, and the axial direction of at least one first through hole 131 is parallel to a second direction. The first direction and the second direction are perpendicular. The electrical conduit can enter the receiving groove 110 through the first through hole 131 of any support portion, which effectively improves the flexibility of the use of the electrical box.

[0073] In embodiments of this disclosure, such as Figure 7 and Figure 9 As shown, the thickness of the surrounding plate 12 opposite to the internal thread 123 is greater than the thickness of the surrounding plate 12 opposite to the first through hole 131.

[0074] Along the height direction of the enclosure 12, the enclosure 12 is divided into a first region and a second region. The first through hole 131 is located in the first region, and the internal thread 123 is located in the second region.

[0075] The first region has a first through hole 131, allowing the electrical conduit to enter the box 10. The first region does not bear external force, and its thickness can be set to be relatively thin, which is beneficial to the lightweight of the box 10. The second region has an internal thread 123. During the movement of the moving part 20 relative to the box 10, the second region bears shear force and friction force. The second region is set to be relatively thick to improve its strength and prevent deformation at the second region, which would affect the reliability of the connection between the two.

[0076] In some embodiments, the material of the box body 10 includes plastic, metal, etc. Taking plastic as an example, the box body 10 can be integrally molded by injection molding. The thickness of the second region is greater than the thickness of the first region, which is beneficial to the lightweight of the box body 10 while meeting the strength requirements.

[0077] In embodiments of this disclosure, such as Figure 7 and Figure 9 As shown, the wall surface of the first through hole 131 is not higher than the end of the internal thread 123 facing the base plate 11.

[0078] Along the axial direction of the internal thread 123, the internal thread 123 has a first end and a second end. The first end is the side facing the base plate 11, and the second end is flush with or slightly lower than the top surface 120 of the housing 10. The wall of the first through hole 131 has a highest point and a lowest point, with the lowest point close to the base plate 11. The first end of the internal thread 123 is higher than the highest point of the hole wall.

[0079] It is understood that the length of the external thread 221 is less than or equal to the length of the internal thread 123. When the movable part 20 moves to the target position, it can prevent the first connecting part 22 from moving to the position corresponding to the first through hole 131 and interfering with the first through hole 131, thus avoiding the situation where the wire conduit cannot enter the box 10 from the first through hole 131.

[0080] In the embodiments disclosed herein, the end of the internal thread 123 facing the base plate 11 is higher than the first through hole 131 to prevent the first connecting part 22 from moving excessively.

[0081] In embodiments of this disclosure, such as Figure 7 and Figure 9 As shown, the internal thread 123 extends to be flush with the top surface 120 of the housing 10.

[0082] With a fixed height of the housing 10, the internal thread 123 extends to be flush with the top surface 120 of the housing 10, so that when the end of the first connecting part 22 is close to the top surface 120 of the housing 10, the distance between the mounting surface 220 and the top surface 120 reaches its maximum value, which is beneficial to maximize the adjustment of the distance between the mounting surface 220 and the top surface 120 of the housing 10.

[0083] In embodiments of this disclosure, such as Figure 10 and Figure 12 As shown, the external thread 221 extends from the end of the first connecting portion 22 away from the mounting plate 21 to the end near the mounting plate 21.

[0084] With the length of the first connecting part 22 being fixed, the external thread 221 extends from the end of the first connecting part 22 away from the mounting plate 21 to the end close to the mounting plate 21, thereby maximizing the length of the external thread 221, which is beneficial for adjusting the distance between the mounting surface 220 and the top surface 120 of the housing 10 to the greatest extent.

[0085] In embodiments of this disclosure, such as Figure 10 , Figure 11 and Figure 12 As shown, the mounting plate 21 includes a support portion 211 and a second connecting portion 212. The support portion 211 has a through groove 210 and is used to support the target object 30. The second connecting portion 212 extends from the inner wall surface of the support portion 211 toward the center of the support portion 211. The second connecting portion 212 has a connecting hole 2121, which is connected to the target object 30 by fasteners.

[0086] Mounting plate 21 includes a support portion 211 and a second connecting portion 212, which can be integrally formed. A through groove 210 passes through the support portion 211, and the shape of the support portion 211 is not specifically limited. If the mounting plate 21 is made of plastic, the second connecting portion 212 and the support portion 211 can be connected by adhesive bonding or integrally formed by injection molding. If the mounting plate 21 is made of metal, the second connecting portion 212 and the support portion 211 can be connected by welding.

[0087] In some embodiments, the support portion 211 may be square in shape and includes four edges connected in sequence. When it is necessary to rotate the movable member 20, the support portion 211 can be pinched with one hand or both hands to apply a rotational action to the movable member 20.

[0088] In some embodiments, the support portion 211 may be polygonal, and the support portion 211 includes a plurality of edges connected in sequence. When it is necessary to rotate the movable member 20, two of the edges can be pinched with one hand or both hands to apply a rotational action to the movable member 20.

[0089] In some embodiments, the support portion 211 may be circular. When it is necessary to rotate the movable member 20, the circumferential surface of the support portion 211 can be held with one hand to apply a rotational action to the movable member 20.

[0090] The second connecting portion 212 can be formed by extending the inner wall surface of the supporting portion 211 along a direction perpendicular to the axis of the supporting portion 211 toward the center of the supporting portion 211. The top surface 120 of the second connecting portion 212 can be flush with the bearing surface of the supporting portion 211. The second connecting portion 212 is provided with a connecting hole 2121, which is a threaded hole. The number of second connecting portions 212 and the number of connecting holes 2121 are set according to actual conditions. For example, one connecting hole 2121 can be provided on the second connecting portion 212.

[0091] For example, there are two second connecting parts 212, and the two second connecting parts 212 are symmetrically arranged about the center face of the bearing part 211.

[0092] For example, there are four second connecting parts 212, which are spaced apart on the inner wall surface of the bearing part 211.

[0093] It is understandable that when there are multiple connecting holes 2121, multiple connection methods can be provided. For example, if the target object 30 is a switch, and the switch has two second connecting holes, the connecting holes 2121 on the second connecting part 212 are defined as first connecting holes. The two second connecting holes can be connected to the two first connecting holes in a first direction, and the two second connecting holes can also be connected to the two second connecting holes in a second direction. The first connecting holes and the second connecting holes are connected by fasteners, including screws.

[0094] The second connecting portion 212 extends from the inner wall surface of the supporting portion 211, and no protruding structure is formed on the circumferential surface of the supporting portion 211, which facilitates operation when rotating the movable part 20. Since the second connecting portion 212 extends from the inner wall surface of the supporting portion 211, it does not occupy a large area, which helps to reduce the weight of the mounting plate 21, and thus the movable part 20.

[0095] In the embodiments of this disclosure, the mounting plate 21 includes a support portion 211 and a second connecting portion 212. The second connecting portion 212 is formed by extending from the inner wall surface of the support portion 211. The support portion 211 is used to support the target object 30, and the second connecting portion 212 is used to fixally connect with the target object 30. Under the premise of satisfying the function of connecting with the target object 30, it is beneficial to the convenience of operation when rotating the movable part 20, and at the same time, it is beneficial to the lightweight of the movable part 20.

[0096] In embodiments of this disclosure, such as Figure 2 and Figure 10 As shown, the circumferential surface of the support portion 211 is located outside the circumferential surface of the box body 10.

[0097] The outer contour dimensions of the support portion 211 are slightly larger than those of the box body 10. During the rotation of the movable part 20, when the support portion 211 is held or pinched by its edge, even when the mounting surface 220 of the movable part 20 is close to the top surface 120 of the box body 10, there is still a suitable operating space between the support portion 211 and the box body 10, which is beneficial to the convenience of hand operation.

[0098] In embodiments of this disclosure, such as Figure 2 , Figure 7 and Figure 8 As shown, the through hole 130 also includes a second through hole 132, and at least one second through hole 132 is provided on the base plate 11.

[0099] The diameter of the second through hole 132 is adapted to the diameter of the conduit. The number of second through holes 132 is not specifically limited. The conduit can enter the box 10 through the second through hole 132 of the base plate 11.

[0100] The electrical box with the second through hole 132 can be used in specific application scenarios. For example, the electrical box can be used in a scenario with two adjacent rooms, defined as Room 1 and Room 2, which share a wall 40. The electrical conduit is installed in Room 1, and the switch needs to be fixed in Room 2.

[0101] A mounting groove is cut into the wall 40, extending through two opposite wall surfaces 41 of the wall 40. The box 10 is then fixed to the mounting groove in the wall 40. The electrical conduit in the first room can pass through the second through hole 132 of the base plate 11 into the box 10. The wires in the conduit are then connected to the terminals of the switch, and the switch is then fixed to the mounting plate 21 of the movable part 20.

[0102] In the embodiments disclosed herein, a first through hole 131 is provided on the enclosure 12 and a second through hole 132 is provided on the bottom plate 11. The electrical conduit can enter the box 10 through the first through hole 131 or through the second through hole 132, which enables the connection of electrical conduits arranged in multiple directions and helps to expand the application scenarios of the electrical box.

[0103] The following specific examples illustrate the application scenarios of the electrical box.

[0104] The electrical box includes a box body 10 and a movable component 20. The box body 10 includes a base plate 11 and a surrounding plate 12 disposed on one side of the base plate 11. The base plate 11 and the surrounding plate 12 enclose a receiving groove 110. An internal thread 123 is machined on the inner wall surface of the upper part of the receiving groove 110. A first through hole 131 is provided on the surrounding plate 12. The movable component 20 includes a mounting plate 21 and a first connecting part 22 disposed on one side of the mounting plate 21. The through groove 210 penetrates the mounting plate 21 and the first connecting part 22. An external thread 221 is machined on the outer wall surface of the first connecting part 22. The mounting plate 21 includes a supporting part 211 and a second connecting part 212. A connecting hole 2121 is provided on the second connecting part 212.

[0105] like Figure 4 As shown, the electrical box is installed on the wall 40 without the decorative panel 50. First, the box body 10 is fixed in the mounting groove of the wall 40. Then, the first connecting part 22 of the movable part 20 is inserted into the receiving groove 110 of the box body 10. The movable part 20 is rotated to adjust the depth of the first connecting part 22 in the box body 10. After observing that the distance between the mounting surface 220 of the movable part 20 and the wall 41 meets the target distance, the rotation is stopped. The next step is to fix the switch to the mounting plate 21. When multiple electrical boxes are installed on the wall 40, it can be ensured that the height of the mounting surface 220 of each electrical box relative to the wall 41 is consistent, ensuring the aesthetics after installation.

[0106] like Figure 5 As shown, the electrical box is installed on the wall 40 with a decorative panel 50. The decorative panel 50 has two opposing surfaces, defined as the front and back surfaces 51, respectively, and there is a certain distance between the decorative panel 50 and the wall 40. A mounting groove is made in the wall 40, and the box 10 is fixed in the mounting groove of the wall 40. Then, the first connecting part 22 of the movable part 20 is inserted into the receiving groove 110 of the box 10. The movable part 20 is rotated to adjust the depth of the first connecting part 22 in the box 10 until the distance between the mounting surface 220 of the movable part 20 and the wall surface 41 meets the target distance, and then the rotation is stopped. The decorative panel 50 is then fixed to the wall 40, and the distance between the back surface 51 of the decorative panel 50 and the wall 40 is the target distance. After the decorative panel 50 is fixed, the mounting surface 220 of the movable part 20 is in contact with the back surface 51 of the decorative panel 50. The next step is to fix the switch to the mounting plate 21. Before installing the decorative panel 50, adjust the distance between the mounting surface 220 of the movable part 20 and the wall 41 to facilitate the subsequent installation work of the operators.

[0107] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this application is not limited thereto. Any changes or substitutions made within the spirit and principles of this disclosure should be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
