Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of strong and weak electricity box construction, in particular to a strong and weak electricity box pre-buried supporting device. BACKGROUND

[0002] Strong and weak electricity boxes are indispensable parts in modern home decoration, each of which bears different functions to ensure the safety and convenience of household electricity and signal transmission. Among them, the strong electricity box, also known as the distribution box, has a voltage of 220V in the box, mainly used for distribution and protection of household electricity, to ensure reliable power supply for various electrical equipment in the home, such as lighting, refrigerator, washing machine, etc., to ensure their normal operation. The weak electricity box is mainly used for concentrating, arranging, distributing and protecting low-voltage signal lines, such as telephone lines, network lines, etc., to ensure the signal transmission quality of the signal lines.

[0003] In the installation and construction process of strong and weak electricity boxes on the standard floor of a building, the strong and weak electricity boxes are generally hidden and installed in the concrete wall. One construction method known to the inventor is to pre-bury a filler at the installation position of the strong and weak electricity boxes before construction, and then after the wall is completed, the filler is removed and the strong and weak electricity boxes are installed in the cavity formed by the filler. This installation method requires accurate control of the shape of the filler to match the outline of the strong and weak electricity boxes, which is difficult to install later, and the filler cannot be reused after being removed, causing waste. In addition, the inventor also knows a pre-burying method, but when it is applied to the installation field of strong and weak electricity boxes, the strong and weak electricity boxes are easily deformed due to the large pouring pressure of the concrete wall during pouring, affecting normal use.

[0023] In the description of the present application, it should be understood that the orientations or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", "clockwise", "counterclockwise", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0024] In order to better understand the technical solutions of the present application, the above technical solutions will be described in detail below in combination with the drawings in the specification and specific embodiments.

[0025] To solve the problem that the strong / weak electric box body cannot withstand a large pouring pressure when pre-buried in a concrete wall body due to limited structural strength, thereby affecting the pre-buried effect and normal use of the box body, the present example discloses a strong and weak electric box pre-buried support device, as shown in Figure 1 which comprises a transverse support assembly 1 and a longitudinal support assembly 2. The transverse support assembly 1 is arranged in a direction parallel to the length of the strong and weak electric box body, thereby providing effective support for the left and right side walls of the box body; the longitudinal support assembly 2 is perpendicular to the transverse support assembly 1 and is arranged in a direction parallel to the height of the strong and weak electric box body, thereby providing reliable support for the upper and lower side walls of the box body. Thus, by providing support force inside the strong and weak electric box body through the two support assemblies 1, the load bearing capacity of the strong and weak electric box body is improved, and problems such as deformation of the box body caused by high-pressure pouring are avoided.

[0026] Since the sizes of different box bodies differ, in order to improve the application range of the device and facilitate the installation and removal of the device in the strong and weak electric box body, in the present embodiment, the lengths of the transverse support assembly 1 and the longitudinal support assembly 2 can be correspondingly adjusted in the axial direction.

[0027] Specifically, as shown inFigure 1 In the embodiment, the transverse support assembly 1 and the longitudinal support assembly 2 respectively comprise a rod shell 3, which is specifically a hollow rod body. A telescopic screw rod 4 is coaxially arranged at both ends of the rod shell 3 in the axial direction of the rod shell 3. In order to realize the adaptive telescopic function of the transverse support assembly 1 or the longitudinal support assembly 2 as required, in the embodiment, referring to Figure 1 , a fixed nut 5 is fixedly welded at each end of the rod shell 3, the fixed nut 5 is matched with the external thread at the telescopic screw rod 4, and the inner diameter of the hollow rod shell 3 is greater than or equal to the outer diameter of the telescopic screw rod 4. Thus, through the threaded connection between the fixed nut 5 and the telescopic screw rod 4, the telescopic screw rod 4 can be screwed in or out along the axial direction of the rod shell 3, so as to realize the adjustment of the length of the transverse support assembly 1 and the longitudinal support assembly 2.

[0028] In addition, considering that the end cross-sectional area of the telescopic screw rod 4 is limited and cannot effectively support the strong and weak electric box body, in the embodiment, referring to Figure 1 , a touch plate 6 is fixedly arranged at the end of the telescopic screw rod 4. Thus, through the contact of the touch plate 6 with the side wall of the strong and weak electric box, the stress area is increased, so as to ensure the effective support of the transverse support assembly 1 or the two longitudinal support assemblies 2 to the box body. In some other embodiments, the touch plate 6 is a rectangular plate. Since the touch plate 6 is fixed at the end of the telescopic screw rod 4 and rotates with the rotation of the telescopic screw rod, in order to avoid the edge of the rectangular touch plate 6 from interfering with the internal components of the box body due to the change of the rotation angle, and thus causing the touch plate 6 to not be in full contact with the side wall of the box body, in this case, the longest side of the rectangular touch plate is less than the depth of the box body of the strong and weak electric box. Thus, when the touch plate 6 rotates at any angle with the telescopic screw rod, the touch plate 6 can be ensured to be in the box body of the strong and weak electric box and in full contact with the side wall of the box body. In the embodiment, the touch plate 6 is a circular plate, and the diameter of the touch plate 6 is less than the depth of the box body of the strong and weak electric box. Thus, when the telescopic screw rod 4 rotates, the edge profile of the touch plate 6 is always circular, and will not interfere with the internal structure of the box body due to the change of the rotation angle.

[0029] In addition, considering that the touch plate 6 is in hard contact with the inner wall of the box body of the strong and weak electric box, in order to avoid damage at the hard contact point after the box body is subjected to the pressure of concrete pouring, in the embodiment, a rubber pad is fixedly arranged at the end face of the touch plate 6 for contacting the inner wall of the box body of the strong and weak electric box. Thus, the contact and stress buffering are realized through the rubber pad, so as to avoid damage to the box body caused by hard contact.

[0030] Referring to Figure 1In the example, two horizontal support assemblies 1 and two longitudinal support assemblies 2 are arranged, the two horizontal support assemblies 1 are arranged in parallel with each other, the two longitudinal support assemblies 2 are arranged in parallel with each other and perpendicular to the horizontal support assemblies 1, thereby forming a cross-shaped structure, and ensuring reliable support of the strong and weak electric box body. In the example, in order to enhance the stability of the device structure, the horizontal support assembly 1 and the longitudinal support assembly 2 are fixedly connected, specifically, the rod shell 3 of the horizontal support assembly 1 and the longitudinal support assembly 2 is welded at the contact point, thereby improving the overall stress stability of the device while facilitating one-time taking and placing of the device.

[0031] In other embodiments, in order to realize the telescopic function of the horizontal support assembly 1 and the longitudinal support assembly 2, referring to Figure 2 , in the example, the rod shell 3 is a hollow internal thread rod, specifically, two internal threads with different thread directions are symmetrically arranged in the rod shell 3, and the internal threads are matched with the external threads of the corresponding telescopic screw rod 4, thereby realizing the rotation of the telescopic screw rod 4 along the rod shell 3 through the thread connection between the telescopic screw rod 4 and the rod shell 3, and realizing the length adjustment of the horizontal support assembly 1 and the longitudinal support assembly 2 as needed.

[0032] In other embodiments, in order to avoid the problem that the vibration during the wall pouring process causes the telescopic screw rod 4 to move relative to the rod shell 3, thereby reducing the support effect, in the example, referring to Figure 3 , the telescopic screw rod 4 is threadedly connected with the tightening nut 7, thereby after the telescopic screw rod is rotated out to the appropriate length, the corresponding tightening nut 7 is tightened, so that the tightening nut 7 is in contact with the end of the fixed nut 5 or the rod shell 3, thereby avoiding the rotation of the telescopic screw rod 4 relative to the rod shell 3.

[0033] In addition, in other embodiments, considering that the contact area between the touch plate 6 and the inner wall of the strong and weak electric box body is also limited, stress concentration is easily caused, thereby increasing the risk of deformation of the strong and weak electric box. Therefore, in the example, referring to Figure 4 , the strong and weak electric box embedded support device further comprises a pad plate 8, the length of the pad plate 8 is matched with the length or width of the strong and weak electric box body, and the width of the pad plate 8 is matched with the depth of the strong and weak electric box body, thereby by arranging the pad plate 8 between the inner wall of the strong and weak electric box body and the corresponding touch plate 6, the stress is dispersed, the uniform stress of each inner wall of the box body is ensured, and the risk of deformation of the box body is avoided to the greatest extent.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0035] Obviously, various modifications and changes can be made to the present application by those skilled in the art without departing from the technical concept and scope of the present application. Thus, the scope of the present application is intended to include such modifications and changes as well, provided that they fall within the scope of the claims of the present application and their equivalents.
