[0041] The terms "first", "second", etc. are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0042] In the description of this embodiment, it should also be noted that unless otherwise clearly specified and defined, the terms "provided with", "set", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0043] As Figures 1 to 8 shown, the present invention discloses a wire box 1, comprising: a box body 10, which is processed from an integrally formed part, and the box body 10 is provided with an outlet 100 and a connection port 101; a cover body 11, which is used to close the outlet 100. Among them, a circumferential adjustment mechanism 14 is provided between the cover body 11 and the outlet 100, and the circumferential adjustment mechanism 14 is used to adjust the position of the cover body 11 in the circumferential direction of the outlet 100 (as Figure 2 shown by the T direction in the figure), in the first state, the cover body 11 rotates relative to the outlet 100 in the circumferential direction, and in the second state, the cover body 11 is stationary relative to the outlet 100.

[0044] That is to say, the wire box 1 mainly consists of a box body 10, a cover body 11, and a circumferential adjustment mechanism 14. Among them, a circumferential adjustment mechanism 14 is provided between the cover body 11 and the outlet 100, that is, the distance adjustment mechanism 14 is arranged between the cover body 11 and the outlet 100, the circumferential adjustment mechanism 14 is arranged on the outlet 100, and the cover body 11 is arranged on the circumferential adjustment mechanism 14. By adjusting the position of the circumferential adjustment mechanism 14 in the circumferential direction of the outlet 100 (as Figure 2 shown by the T direction in the figure), the orientation of the cover body 11 in the circumferential direction of the outlet 100 can be adjusted, so that the orientation of the cover body 11 can meet different requirements, improving the applicability of the wire box 1 and facilitating the operation and use by the staff.

[0045] In the prior art, after construction is completed, different pointing icons are generally set on the cover body to guide the route direction. However, since the cover body and the outlet of the box body are fixedly connected or clamped by bolts, the orientation of the cover body cannot be effectively adjusted in the circumferential direction of the outlet, and pointing errors and mistakes are likely to occur. For the present invention, after construction is completed, the circumferential adjustment mechanism 14 can be installed at the outlet 100, and the circumferential adjustment mechanism 14 is in the first state. In the first state, the circumferential adjustment mechanism 14 can drive the cover body 11 to rotate relative to the outlet 100 along the circumferential direction of the outlet 100, so that the cover body 11 can be adjusted to any direction in the circumferential direction of the outlet 100, and the orientation of the cover body 11 can be effectively adjusted to ensure that the orientation of the cover body 11 is accurate. After the adjustment is completed, operate the circumferential adjustment mechanism 14 to make it in the second state. In the second state, the cover body 11 is stationary relative to the outlet 100, that is, in the second state, the circumferential adjustment mechanism 14 is locked. During the specific use process, in the first state, the circumferential adjustment mechanism 14 can also be adjusted to the required direction, then the circumferential adjustment mechanism 14 is adjusted to the second state, and then the cover body 11 is installed on the circumferential adjustment mechanism 14. Such an operation is more convenient and simple and easy to use.

[0046] With the above technical solution, by providing a circumferential adjustment mechanism between the cover body and the outlet, the cover body can be driven to rotate relative to the outlet along the circumferential direction of the outlet, so that the cover body can be adjusted to any direction in the circumferential direction of the outlet, and the orientation of the cover body can be effectively adjusted.

[0047] It should be noted that the specific structure of the circumferential adjustment mechanism of the present invention is not limited and can be reasonably set according to actual needs, as long as the circumferential adjustment mechanism can adjust the orientation of the cover body. Specifically, refer to Figure 3 and in combination with Figure 8 As shown, in the present invention, the circumferential adjustment mechanism 14 includes an adjustment part 141 and a locking part 140. Both the adjustment part 141 and the locking part 140 are connected to the outlet 100, and the cover body 11 is arranged on the adjustment part 141. In the first state, the locking part 140 releases the adjustment part 141, and the adjustment part 141 and the cover body 11 can rotate relative to the outlet 100 along the circumferential direction. In the second state, the locking part 140 locks the adjustment part 141, and the adjustment part 141 and the cover body 11 are stationary relative to the outlet.

[0048] Refer to Figure 3 and in combination with Figure 8As shown, in this embodiment, the circumferential adjustment mechanism 14 mainly consists of an adjustment part 141 and a locking part 140. Both the adjustment part 141 and the locking part 140 are arranged on the upper part of the outlet 100, and the cover body 11 is arranged on the adjustment part 141. Among them, both the locking part 140 and the adjustment part 141 are annular structures, and the locking part 140 and the adjustment part 141 are in abutment through inclined surfaces. In the first state, the locking part 140 will loosen the adjustment part 141, so that there is a gap between the inclined surfaces of the two. At this time, the adjustment part 141 can rotate freely at any angle. Therefore, the cover body 11 can rotate arbitrarily following the adjustment part 141 and can face any direction in the circumferential direction of the outlet 100. In the second state, the locking part 140 will abut against the adjustment part 141, and the inclined surface on the locking part 140 can press the adjustment part 141 tightly, making the adjustment part 141 unable to rotate. At this time, the adjustment part 141 remains relatively stationary with the outlet 100. Therefore, the cover body 11 also remains relatively stationary with the outlet 100 and can be fixed in the required orientation.

[0049] It should be further noted that the present invention does not limit the installation method of the circumferential adjustment mechanism and can be reasonably set according to actual needs as long as the circumferential adjustment mechanism can be adjustably arranged on the outlet. Specifically, as shown in Figure 3 As shown, in this embodiment, an installation groove 143 is provided at the upper end of the outlet 100, and the circumferential adjustment mechanism 14 is arranged in the installation groove 143. Or, the outlet 100 is provided with a distance adjustment mechanism (not shown in the figure), and an installation groove 143 is provided at the upper end of the distance adjustment mechanism, and the circumferential adjustment mechanism 14 is arranged in the installation groove 143.

[0050] That is to say, when the circumferential adjustment mechanism 14 is directly connected to the upper end of the outlet 100, an installation groove is provided at the upper end of the outlet 100, and both the adjustment part 141 and the locking part 140 of the circumferential adjustment mechanism 14 are arranged in the installation groove. Among them, both the locking part 140 and the adjustment part 141 are annular structures, and the locking part 140 and the adjustment part 141 are in abutment through inclined surfaces, and the locking part can press or loosen the adjustment part 141. Specifically, as shown in Figure 3 and in combination with Figure 8 As shown, the locking part 140 is arranged in the installation groove 143 at the end of the outlet 100 through a fastener. By tightening and loosening the fastener, the locking part 140 can lock and loosen the adjustment part 141.

[0051] If the circumferential adjustment mechanism 14 is connected to the end of the outlet 100 through other connection structures, such as a distance adjustment mechanism, at this time, the installation groove 143 can also be arranged on the distance adjustment mechanism, so that the cover body 11 can not only rotate in the circumferential direction but also adjust the cover body 11 in the axial direction of the outlet (such as Figure 1 and Figure 3The height position in the direction A (as shown in the figure) realizes the multi-dimensional adjustment of the cover body 11, which is more convenient for the use and operation of the wire box 1. In other embodiments, the circumferential adjustment mechanism can also be connected to the outlet in other ways, and the present invention does not limit this and can be reasonably selected according to actual needs.

[0052] Further, referring to Figures 1 to 8 As shown, in this embodiment, the box body 10 is processed from an integrally formed part, and there is no connection gap between the side surfaces 103 and the end surfaces 102, without the need for welding and splicing, and it can well achieve sealing structurally, improving the waterproof performance of the wire box 1. At the same time, the box body 10 is also provided with an outlet 100 and a connection port 101. Among them, the outlet 100 is provided on the end surface 102 of the box body 10 for the pipeline to pass through and for the staff to operate the pipeline in the wire box 1 through the outlet 100. The connection port 101 is provided on the side surface 103 of the box body 10, and an external pipeline or wire groove can be hermetically connected to the connection port 101, so that the pipeline or wire groove and the wire box 1 form a complete pipeline system. In addition, for the convenience of connecting the outlet 100 and the cover body 11, referring to Figures 1 to 8 As shown, in this embodiment, the outlet extends from the end surface 102 of the box body 10, which is convenient for the disassembly and assembly of the circumferential adjustment mechanism 14 and the cover body 11.

[0053] It should be explained that the "pipeline" in this article refers to the general term for various pipelines, wires, cables, etc., and can include structures such as cables, optical fibers, and wire harnesses with protective sleeves.

[0054] Specifically, in this embodiment, the box body 10 is mainly made of alloy materials (such as aluminum alloy, zinc alloy, nickel alloy, etc.). Preferably, the alloy material is aluminum alloy material, and it is integrally formed by die-casting. This can not only improve the sealing performance of the entire box body 10, but also the aluminum alloy material has electrical conductivity and can be connected to a metal pipeline or wire groove. It can not only be used as the grounding wire of the pipeline system, simplifying the structure of the pipeline system, but also can shield the external electric field or magnetic field of the box body 10, avoiding the interference of the external electric field or magnetic field of the box body 10 on the electrical components in the box body 10, making the entire pipeline system operate more stably and reliably. In other embodiments, the box body can also be integrally formed by cast iron, hard plastic or resin materials, and the present invention does not limit this, as long as the box body can be integrally formed and has good sealing performance.

[0055] It can be seen that by using a box body processed from an integrally formed part, there is no connection gap between the side surfaces and the end surfaces, without the need for welding and splicing, and it can well achieve sealing structurally and improve the strength of the box body, making the wire box have good sealing and waterproof performance.

[0056] Further, referring to Figures 1 to 8As shown, in this embodiment, the end face 102 of the box body 10 is a plane or an arc surface protruding towards the outside of the box body 10. Specifically, the end face 102 of the box body 10 includes an upper end face and a lower end face. Therefore, it can be that the upper end face of the box body 10 is an arc surface protruding towards the outside of the box body 10, or the lower end face of the box body 10 is an arc surface protruding towards the outside of the box body 10, or both the upper end face and the lower end face of the box body 10 are arc surfaces protruding towards the outside of the box body 10. Similarly, the outlet 100 can be provided on the upper end face of the box body 10, or on the lower end face of the box body 10, or on both the upper end face and the lower end face of the box body 10 at the same time. The present invention does not limit this and can be reasonably set according to actual needs. At the same time, the connection port 101 is provided on the side face 103 of the box body 10. It can be provided on one side face 103, or on two opposite side faces 103 or two adjacent side faces 103, or on three side faces 103, or on four side faces 103. The present invention also does not limit this and can be reasonably set according to actual needs.

[0057] More specifically, referring to Figures 1 to 8 As shown, in this embodiment, the upper end face of the box body 10 is an arc surface protruding towards the outside of the box body 10, the outlet 100 is provided on the upper end face of the box body 10, and the outlet 100 is provided with a cover body 11. During use, the box body 10 needs to be buried in concrete. By setting the upper end face of the box body 10 as an arc surface protruding towards the outside of the box body 10, the pressure and stress applied by the concrete on the upper end face can be well dispersed, so that the box body 10 can bear greater pressure and stress, and the strength of the box body 10 is improved. At the same time, the cover body 11 can close the outlet 100 through the circumferential adjustment mechanism 14 to ensure that the concrete layer does not cover the outlet 100 and ensure that the outlet 100 can be used.

[0058] Referring to Figure 7 As shown, in this embodiment, the upper end face of the box body 10 is provided with an outlet 100, and the lower end face of the box body 10 is provided with a lower outlet 106. That is, outlets are provided on both the upper end face and the lower end face of the box body 10. By providing the lower outlet 106 on the lower end face of the box body 10, not only can the function of threading downward through the lower outlet 106 be realized on the basis of threading upward through the outlet 100, but also the effect of exhausting air and dissipating heat can be realized through the lower outlet 106. In addition, if water or sundries (such as concrete debris) enter the box body 10 or the wire pipe or wire groove by accident, they can be discharged in time through the lower outlet 106 to minimize the influence of water or sundries on the pipelines in the box body 10.

[0059] Furthermore, in order to prevent the lower outlet 106 from being exposed for a long time, which affects the aesthetics and service performance, referring to Figure 7As shown, in this embodiment, the lower outlet 106 is provided with a filter screen 107, and / or a sealing cover 108. That is, the lower outlet 106 can be provided with only the filter screen 107, or only the sealing cover 108, or both the filter screen 107 and the sealing cover 108 at the same time. Among them, the filter screen 107 can be set at a position flush with the inner surface of the bottom of the lower outlet 106 and the box body 10, or inside the lower outlet 106, or sleeved on the lower outlet 106. The present invention does not limit this and can be reasonably set according to actual needs as long as it can block the lower outlet, and it is used to block sundries such as mosquitoes and mice from entering without affecting the exhaust heat dissipation of the pipeline system.

[0060] See Figures 1 to 8 As shown, in this embodiment, the shape of the outlet 100 is a circular outlet. By setting the outlet 100 of the box body 10 as a circular outlet, it is convenient for the installation and disassembly between the box body 10, the circumferential adjustment mechanism 14 and the cover body 11, and it is also easy to process the circumferential adjustment mechanism 14 and the box body 10.

[0061] In addition, since the box body 10 is made by integral molding, when demolding, there will be burrs or edges at the junctions between the outlet 100, the connection port 101 and the inner wall of the box body 10, which will scratch the pipelines passing through the box body 10 or the staff. To avoid scratching the pipelines or the staff, see Figure 6 and Figure 7 As shown, in this embodiment, a protective sleeve 13 is provided in the box body 10, and the protective sleeve 13 is arranged at the outlet 100, and / or at the port of the connection port 101 located inside the box body 10. That is, the protective sleeve 13 can be only arranged inside the outlet 100, or only arranged at the port of the connection port 101 located inside the box body 10, or arranged inside the outlet 100 and at the port of the connection port 101 located inside the box body 10 at the same time. The present invention does not limit this and can be reasonably set according to actual needs. By setting the protective sleeve 13, the burrs or edges existing at the junction are covered by the protective sleeve 13 to avoid scratching the staff or the pipelines passing through the box body 10. Specifically, the protective sleeve 13 can be a nylon sleeve, a silica gel sleeve, a rubber sleeve or a plastic sleeve, or a metal sleeve such as a copper sleeve, etc. The present invention does not limit this and can be selected according to actual needs as long as the protective sleeve can be sleeved on the outlet or the port of the connection port located inside the box body to avoid scratching the pipelines or the staff.

[0062] Furthermore, see Figures 1 to 8As shown, in this embodiment, the cross-sectional shape of the box body 10 is rectangular. The cross-section of the box body 10 is the box body cross-section intercepted from the side surface 103 of the box body 10 along the direction parallel to the end face of the box body 10. The box body 10 with a rectangular cross-section is widely used in various types of wire boxes 1 and is a relatively common type in the wire box 1. It can be well applied to various occasions, such as the layout of internal pipelines in shopping malls or subway lines, and has good universality. In other embodiments, the cross-sectional shape of the box body can also be other types, such as polygons, circles, ellipses, and irregular shapes, etc. The present invention does not limit this and can be selected according to actual needs.

[0063] It should be noted that the present invention does not limit the specific structure and shape of the cover body, and can be reasonably set and selected according to actual needs, as long as the cover body can close the outlet. Specifically, refer to Figures 1 to 4 and combine with Figure 8 As shown, in this embodiment, the cover body 11 includes a first cover body 110. The first cover body 110 is arranged on the circumferential adjustment mechanism 14 and can close the outlet 100. After the construction is completed, the circumferential adjustment mechanism 14 is installed at the outlet 100 and adjusted to the required direction position, and then the first cover body 110 is installed on the distance adjustment mechanism 14. Specifically, the first cover body 110 is installed on the adjustment part 140, and the outlet 100 of the box body 10 is closed by closing the opening in the upper part of the adjustment part 140, realizing the sealing of the box body 10.

[0064] In addition, due to the thickness of the concrete layer in different construction stages and the subsequent need to construct a leveling layer on the concrete layer and lay building materials such as floors on the leveling layer, the height of the building layer relative to the outlet is constantly changing. In order to prevent the outlet from being covered, in this embodiment, the first cover body 110 can also be directly installed on the outlet 100 of the box body 10, and it is necessary to ensure that the height of the first cover body 110 also changes. Therefore, first cover bodies 110 with different heights need to be set. When the thickness of the building layer changes, the first cover body 110 with a different height can be replaced to ensure that the upper end of the first cover body 110 is higher than the building layer or maintains a relative height with the building layer. For example, at the factory or during the construction stage of pouring the concrete layer, since the concrete layer is not too thick, a first cover body 110 that is a little shorter than that shown in Figure 4 can be used. During the subsequent construction of the leveling layer, the first cover body 110 shown in Figure 4 can be used. After the final construction is completed, the first cover body 110 with a flat upper end surface shown in Figures 1 to 3 can also be used to prevent the outlet 100 and the first cover body 110 from being covered by building materials, and can also make the cover body 11 close the outlet 100 to ensure that the outlet 100 can be used.

[0065] Further, referring to Figure 8 and in combination with Figures 1 to 7 As shown, in this embodiment, the first cover 110 is provided with a first clamping portion (not shown in the figure), and the circumferential adjustment mechanism 14 is provided with a second clamping portion 142. The first cover 110 and the circumferential adjustment mechanism 14 are connected through the first clamping portion and the second clamping portion 142. Specifically, the first clamping portion is a convex portion provided on the first cover 110, and the second clamping portion 142 is a groove provided on the inner wall of the adjustment portion 141. After the circumferential adjustment mechanism 14 is adjusted, align the first clamping portion on the first cover 110 with the second clamping portion 142 on the adjustment portion 141 and then tighten it to achieve a tight connection between the first cover 110 and the adjustment portion 141. The connection between the first cover 110 and the adjustment portion 141 is achieved through a clamping form, which facilitates the installation and disassembly of the first cover 110 and can also play a role in closing the opening 100. In order to achieve a better sealing effect, a sealing gasket can also be provided on the upper part of the adjustment portion 141 to achieve a preliminary waterproof effect.

[0066] In other embodiments, the first cover can also be connected to the adjustment portion through other connection methods. For example, the first cover is provided with an internal thread (or external thread), and the adjustment portion is provided with an external thread (or internal thread). The first cover and the adjustment portion are hermetically connected through the thread, or the first cover is directly installed on the upper end of the adjustment portion through a fastener (such as a screw, etc.). The present invention does not limit this and can be reasonably set according to actual needs as long as the first cover and the adjustment portion can be hermetically connected and the opening can be closed.

[0067] To achieve better sealing performance and waterproof effect, referring to Figure 2 and in combination with Figures 7 to 8 As shown, in this embodiment, the cover 11 further includes a second cover 111, and the second cover 111 is disposed in the outlet 100 and can be covered by the first cover 110.

[0068] That is, after the second cover 111 is connected to the outlet 100, the first cover 110 can cover the second cover 111. After the first cover 110 achieves preliminary waterproofing, the second cover 111 is connected to the outlet 100 to achieve double-layer sealing and waterproofing. At the same time, referring to Figure 3As shown, a sealing groove 112 is provided on the outer side wall of the second cover body 111, and a sealing ring 113 is provided in the sealing groove 112, further improving the sealing performance and waterproof effect of the cover body 11 on the opening 100, ensuring that the outlet 100 can be closed by the cover body 11. In this embodiment, the first cover body 110 and the second cover body 111 are two independent components. During installation, first connect the second cover body 111 to the outlet 100 so that the second cover body 111 closes the outlet 100, and then connect the first cover body 110 to the adjusting portion 141 so that the first cover body 110 further closes the outlet 100, achieving double-layer sealing and waterproofing of the outlet 100, and ensuring that the junction box 1 has good sealing performance and waterproof effect.

[0069] It should be noted that the present invention does not limit the connection method between the second cover body and the outlet, and can be reasonably set according to actual needs, as long as the second cover body can be hermetically connected to the outlet. Specifically, refer to Figure 3 and in combination with Figure 8 As shown, in this embodiment, the second cover body 111 is provided with an external thread, and the inner wall of the outlet 100 is provided with an internal thread. The second cover body 111 is threadedly connected to the outlet 100, and a sealing ring 113 is provided between the outer side wall of the second cover body 111 and the inner wall of the outlet 100. Among them, a sealing groove 112 is provided on the outer side wall of the second cover body 111, and a sealing ring 113 is provided in the sealing groove 112 to achieve a sealed connection between the two. During the process of screwing the second cover body 111 into the outlet 100, the sealing groove 112 of the second cover body 111 can abut against the sealing ring 113, so that the sealing ring 113 is hermetically attached to both the inner wall of the outlet 100 and the second cover body 111, realizing the closure of the outlet 100 and improving the closing effect of the cover body 11. In this case, the second cover body 111 can be fixedly connected to the first cover body 110 or be a whole component. When the first cover body 110 is rotated, the second cover body 111 will also be rotated, realizing the synchronous installation of the first cover body 110 and the second cover body 111, which is convenient for the disassembly and assembly of the cover body 11.

[0070] In another embodiment of the present invention, the second cover body and the outlet are connected by pressing and sealing. Specifically, neither the inner wall of the outlet nor the outer wall of the second cover body is provided with a thread. Instead, a sealing groove is opened on the outer side of the second cover body, the sealing ring is sleeved in the sealing groove, and then the second cover body provided with the sealing ring is pressed into the outlet, so that the sealing ring on the second cover body is closely attached to the inner wall of the outlet, realizing the sealed connection between the second cover body and the outlet. In other embodiments, the second cover body can also be connected to the adjusting portion by other connection methods. For example, the second cover body is provided with a convex portion, and the adjusting portion is provided with a groove. The second cover body and the adjusting portion are connected by forms such as clamping of the convex portion and the groove. The present invention does not limit this and can be reasonably set according to actual needs, as long as the second cover body can be hermetically connected to the adjusting portion.

[0071] In addition, when the upper end surface of the first cover body is a flat cover body, the construction stage has been completed at this time, and the installation of electrical facilities is required. There may be electrical components such as socket strips or indicating lamps on the first cover body. To facilitate the connection between the electrical components on the first cover body and the lines in the box body, in this embodiment, an outlet hole can be opened on the second cover body, and the lines in the box body can be electrically connected to the electrical components on the first cover body through the outlet hole. At the same time, to ensure the sealing performance of the box body, a sealing rubber sleeve can be sleeved on the outlet hole when wiring, so as to ensure the sealing of the box body even when wiring.

[0072] Furthermore, since the application scenario of the wire box 1 is throughout the entire cycle of building construction and needs to be kept closed for a long time, it is very difficult to open and seal the cover body 11 by hand when replacing the cover body 11 or threading the wire, and a disassembly and assembly tool is required for the disassembly and assembly operation of the cover body 11. To facilitate the cooperation between the cover body 11 and the disassembly and assembly tool, as shown in Figure 4 and Figure 8 In this embodiment, a docking portion is provided on the cover body 11, and the cover body 11 can be docked with the disassembly and assembly tool through the docking portion. Among them, the docking portion can be provided on the first cover body 110, or on the second cover body 111, or on both the first cover body 110 and the second cover body 111 at the same time, which is convenient for the disassembly and installation of the cover body 11. See Figure 4 and in combination with Figure 8 As shown, in this embodiment, the docking portion includes a docking protrusion or a docking groove 114. Preferably, the docking portion is provided on the second cover body 111. Since the second cover body 111 is arranged inside the outlet 100, by providing the docking portion, the disassembly and assembly of the second cover body 111 can be facilitated. Among them, the docking portion can be a docking protrusion (not shown in the figure) or a docking groove 114 (as shown in Figure 8 ), and the present invention does not limit this, and can be reasonably set according to actual needs as long as it can facilitate the disassembly and assembly of the cover body.

[0073] See Figure 4 As shown, in another embodiment of the present invention, the docking portion includes a docking groove 114 and a center groove 115. The docking groove 114 is arranged on the upper end surface of the cover body 11 and extends along the radial direction of the cover body 11 to the edge of the cover body 11. The docking grooves 114 are distributed at intervals along the circumferential direction of the cover body 11, and the center groove 115 is arranged at the center of the upper end surface of the cover body 11.

[0074] That is to say, the upper end surface of the cover body 11 is provided with a docking groove 114 and a center groove 115. Among them, the docking grooves 114 are distributed at intervals along the circumferential direction of the cover body 11, and the number of the docking grooves 114 can be set according to actual needs and the structure of the disassembly and assembly tool. Specifically, see Figure 4As shown, in another embodiment, three docking grooves 114 are provided on the cover body 11. The three docking grooves 114 are evenly spaced on the upper end surface of the cover body 11. When disassembling or installing the cover body 11, disassembly and installation tools such as a three-jaw clamp can be used for operation, which facilitates the disassembly and installation of the cover body 11. At the same time, the docking grooves 114 extend along the radial direction of the cover body 11 to the edge of the cover body 11, which facilitates the removal of residual building materials (such as sediment, debris, etc.) on the cover body 11, ensuring that the docking grooves 114 can be effectively docked with the disassembly and installation tools.

[0075] See Figure 4 As shown, in this embodiment, the central groove 115 is provided at the center of the upper end surface of the cover body 11. During the installation process of the cover body 11, it is necessary to keep the cover body 11 horizontal. For this purpose, a measuring device such as a level can be placed in the central groove 115 to ensure the accuracy of the measurement. After the construction is completed, plastic markers (such as road signs, guiding signs, etc.) can be filled in the central groove 115 or guiding tape can be pasted to assist in decoration, so as to better play the role and use of the cover body 11. In other embodiments, the docking part on the cover body can also be of other shapes and structures, and the present invention does not limit this, and can be reasonably set according to actual needs as long as the docking part can be effectively docked with the disassembly and installation tools.

[0076] Further, see Figures 1 to 8 As shown, in this embodiment, the wire box 1 further includes a bottom plate 12. The lower part of the box body 10 is provided with a bottom opening 105, and the bottom plate 12 is hermetically connected to the lower part of the box body 10 to close the bottom opening 105. That is, the lower part of the box body 10 is an open bottom opening 105. By providing the bottom opening 105, it is convenient for the die casting of the box body 10, and the bottom plate 12 is hermetically connected to the lower part of the box body 10 to close the bottom opening 105.

[0077] Specifically, see Figure 3 And in combination with Figures 4 to 7As shown, in this embodiment, a packing groove 120 is provided at the edge of the bottom plate 12 or the box body 10. The edge of the box body 10 or the bottom plate 12 is snapped into the packing groove 120, and the two are hermetically connected through the sealant in the packing groove 120. That is to say, the box body 10 and the bottom plate 12 are hermetically connected by filling sealant. Among them, the packing groove 120 can be provided on the bottom plate 12 or on the box body 10. Fill the packing groove 120 with sealant, and then snap the edge of the box body 10 or the bottom plate 12 into the packing groove 120, so that the lower edge of the box body 10 is completely immersed in the sealant, realizing a reliable connection and seal between the box body 10 and the bottom plate 12, and ensuring the sealing performance and waterproof performance of the entire junction box 1. Among them, the sealant can be epoxy resin glue or silicone glue, etc. The present invention does not limit this, and can be reasonably set according to actual needs, as long as a reliable sealed connection between the box body and the bottom plate can be achieved.

[0078] In other embodiments, the bottom plate and the box body can also be hermetically connected by other connection methods. For example, a sealing strip can be provided between the bottom plate and the box body, and the bottom plate is hermetically connected to the bottom plate by pressing the sealing strip with a fastener. The present invention does not limit this either, and can be reasonably set according to actual needs, as long as a reliable sealed connection between the box body and the bottom plate can be achieved.

[0079] In addition, in order to stably and reliably embed the junction box 1 in the building layer and prevent the junction box 1 from moving due to the extrusion of the concrete layer, see Figures 1 to 8 As shown, in this embodiment, mounting lugs 104 are provided at the edge of the bottom plate 12 or the lower edge of the box body 10. The mounting lugs 104 are integrally formed with the bottom plate 12 or the box body 10. That is to say, the mounting lugs 104 can be only provided at the edge of the bottom plate 12, or only provided at the lower edge of the box body 10, or can be provided at both the lower edge of the box body 10 and the edge of the bottom plate 12. The present invention does not limit this and can be set according to actual needs. During installation, the junction box 1 is integrally fixed in the building base through the cooperation of bolts or other fasteners with the mounting lugs 104, which can well fix the junction box 1 and prevent the junction box 1 from moving due to the extrusion of the concrete layer.

[0080] The present invention also discloses a pipeline system, including a wire groove and the junction box 1 in any one of the above embodiments. The connection port 103 of the wire groove and the junction box 1 is hermetically connected, and the wire groove and the junction box 1 are jointly embedded in the building body. The cover body 10 of the junction box 1 can be adjusted in the circumferential direction to the required direction under the adjustment of the circumferential adjustment mechanism 14.

[0081] With the above technical solution, by providing a circumferential adjustment mechanism between the cover body and the outlet, it is possible to drive the cover body to rotate relative to the outlet along the circumference of the outlet, so that the cover body can be adjusted to face any direction on the circumference of the outlet, and the orientation of the cover body can be effectively adjusted.

[0082] Although the present invention has been illustrated and described by referring to certain preferred embodiments thereof, those of ordinary skill in the art should understand that the above content is a further detailed description of the present invention in conjunction with specific embodiments, and it cannot be determined that the specific implementation of the present invention is only limited to these descriptions. Those skilled in the art can make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
