In the construction process of a building project, it is often necessary to embed a concealed box on the steel skeleton before pouring the wall concrete. In terms of the current construction process, any pre-buried box needs to be prepared on site in advance, and a dedicated person will be responsible for the packaging and reinforcement work. In order to save costs and reuse resources, the traditional construction process generally uses discarded short PVC wire pipes to make a "cross" shape and tie them back to the top for reinforcement, and then wrap plastic tape to seal the box to prevent the box from deforming and causing leakage and corrosion. However, this approach has great quality risks, and improper reinforcement can easily cause the box to deform, thereby leaking and damaging the box. In addition, this approach cannot flexibly adjust the size according to the size of the box, wasting manpower and time costs.

[0020] The utility model will be further described below in conjunction with the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 It is a structural schematic diagram of the concealed distribution box reinforcement device of the utility model. DETAILED DESCRIPTION

[0023] like Figure 1The concealed distribution box reinforcement device shown comprises a reinforcement component 1 arranged on the concealed distribution box, the reinforcement component 1 comprises a mounting mechanism 2, a driving mechanism 3 connected to the mounting mechanism 2, and a supporting mechanism 4 for supporting the inner wall of the box body to prevent the box body from being deformed and connected to the driving mechanism 3, the driving mechanism 3 comprises a fixed connecting member 31, a movable connecting member 32 connected to the fixed connecting member 31, and a driving member 33 located between the fixed connecting member 31 and the movable connecting member 32, the fixed connecting member 31 is rotatably connected to the mounting mechanism 2 at one end away from the movable connecting member 32, the movable connecting member 32 is rotatably connected to the supporting mechanism 4 at one end away from the fixed connecting member 31, and when the driving member 33 is rotated, the supporting mechanism 4 moves relative to the mounting mechanism 2 to approach or move away from the inner wall of the box body;

[0024] The invention relates to a concealed switch box reinforcement device, wherein a driving mechanism is provided, the driving mechanism comprises a fixed connection piece, a movable connection piece connected to the fixed connection piece, and a driving member located between the fixed connection piece and the movable connection piece, wherein one end of the fixed connection piece away from the movable connection piece is rotatably connected to the installation mechanism, and one end of the movable connection piece away from the fixed connection piece is rotatably connected to the support mechanism, and the support mechanism can support the inner wall of the box body to prevent the box body from deforming. When the user rotates the driving member, the fixed connection piece and the movable connection piece rotate accordingly, thereby driving the support mechanism to move relative to the installation mechanism, and the support mechanism can be close to the inner wall of the box body to achieve the effect of supporting the inner wall of the box body, effectively solving the problem of using discarded short PVC wire tubes to make a "cross" shape and tie them back to the top for reinforcement, and then wrapping plastic tape to seal the box, which is easy to cause the box body to deform due to improper reinforcement, thereby leaking and damaging, and this method cannot flexibly adjust the size according to the size of the box, which wastes manpower and time costs.

[0025] By utilizing the rotating driving member, the fixed connecting member and the movable connecting member rotate accordingly, so that the supporting mechanism moves relative to the mounting mechanism, thereby achieving the effect of adjusting the distance between the supporting mechanism and the mounting mechanism. The setting of the adjustable distance can meet the needs of boxes of different sizes, which is conducive to improving the applicability and versatility of the reinforcement component.

[0026] By utilizing the combined structure of fixed connecting parts, movable connecting parts and driving parts, the connection between the supporting mechanism and the mounting mechanism is made simpler, which is convenient for installation and adjustment, thus saving the user's installation time and reducing the complexity of the installation process.

[0027] By arranging a reinforcement component to support the inner wall of the box body, when the mold is turned over, the user can remove the reinforcement component in the box body for use in the next concealed box body, and the reinforcement component can be recycled, which is conducive to saving resources.

[0028] Optionally, in some embodiments, the mounting mechanism 2 may be made of a material with a relatively high hardness, such as metal, plastic, stone, or wood.

[0029] Furthermore, as a preferred embodiment of the present invention but not a limitation, the mounting mechanism 2 is made of steel, which has a low manufacturing cost.

[0030] like Figure 1 The fixed connecting member 31 shown in the figure is provided with a first thread 11, and the movable connecting member 32 is provided with a second thread 12 which is opposite to the first thread 11 in direction;

[0031] Furthermore, by providing threads with different rotation directions on the fixed connector 31 and the movable connector 32, rotation between the fixed connector 31 and the movable connector 32 can be achieved simultaneously, thereby being able to adjust the distance and position between the support mechanism 4 and the inner wall of the box body, which is beneficial to improving the support and reinforcement effects.

[0032] Furthermore, by setting threads with different rotation directions, the adjustment between the mounting mechanism 2 and the supporting mechanism 4 is made more flexible. The user can achieve precise adjustment between the supporting mechanism 4 and the inner wall of the box body by rotating the driving member 33, which is convenient for the user to adjust according to needs during actual use and ensure stable support and reinforcement effects.

[0033] like Figure 1 The mounting mechanism 2 shown in the figure has a first auxiliary member 21 matching the first thread 11 at one end close to the fixed connecting member 31, and the supporting mechanism 4 has a second auxiliary member 41 matching the second thread 12 at one end close to the movable connecting member 32;

[0034] Optionally, in some embodiments, a thread that cooperates with the first thread 11 is provided in the mounting mechanism 2 , and a thread that cooperates with the second thread 12 is also provided in the supporting mechanism 4 .

[0035] Furthermore, as a preferred embodiment of the present invention but not a limitation, the mounting mechanism 2 is provided with a first auxiliary part 21 that cooperates with the first thread 11, and the supporting mechanism 4 is provided with a second auxiliary part 41 that cooperates with the second thread 12, and both the first auxiliary part 21 and the second auxiliary part 41 are nuts.

[0036] Furthermore, by providing the first auxiliary component 21 and the second auxiliary component 41, the threads on the fixed connecting component 31 and the movable connecting component 32 can be effectively matched to ensure the stability and firmness of the connection, avoid loosening or falling off during use, and effectively ensure the safety and reliability of the reinforcement component 1.

[0037] Furthermore, the first auxiliary part 21 cooperates with the first thread 11, and the second auxiliary part 41 cooperates with the second thread 12, so that the connection between the driving mechanism 3 and the mounting mechanism 2 and the supporting mechanism 4 is more precise, and the adjustment between the supporting mechanism 4 and the inner wall of the box body is more accurate, thereby effectively ensuring the accuracy and stability of the reinforcement effect and improving the overall quality of the device.

[0038] like Figure 1 The support mechanism 4 shown includes a support connection portion 42 connected to the movable connection member 32, and a support bearing surface 43 connected to the support connection portion 42 and extending along the length direction of the inner side wall of the box body;

[0039] Furthermore, the supporting surface 43 is extended along the length direction of the inner wall of the box body, which is conducive to providing a more stable supporting effect, effectively supporting the inner wall of the box body, and ensuring the stability and reliability of the reinforcement component 1.

[0040] Furthermore, the provision of the support bearing surface 43 can increase the load-bearing capacity of the support mechanism 4 , expand the support range, reduce the pressure on the support surface, effectively disperse the load-bearing capacity of the inner wall of the box body, and improve the load-bearing capacity of the reinforcement component 1 .

[0041] Furthermore, the support bearing surface 43 extending along the length direction of the inner wall of the box body can achieve uniform support for the inner wall, avoid deformation or displacement caused by local uneven support, and ensure the stability of the inner wall of the box body and the integrity of the overall structure.

[0042] Optionally, the supporting surface 43 is rectangular.

[0043] like Figure 1 The supporting connection portion 42 shown in the figure is provided with a first opening at one end close to the movable connection member 32, and the movable connection member 32 is detachably connected to the supporting connection portion 42 through the first opening;

[0044] Specifically, the support connection part 42 is a steel pipe, one end of the support connection part 42 is connected to the support bearing surface 43, and the other end of the support connection part 42 is provided with a first opening. The movable connection part 32 is inserted into the support connection part 42 through the first opening, and the second auxiliary part 41 is welded on the first opening so that the movable connection part 32 is threadedly connected to the support connection part 42.

[0045] Furthermore, a first opening is provided at one end of the support connection portion 42 near the movable connection member 32, so that the movable connection member 32 can be detachably connected to the support connection portion 42 through the opening, which facilitates the installation and disassembly process of the support mechanism 4, simplifies the operating steps, and improves the convenience and efficiency of the operation.

[0046] like Figure 1The mounting mechanism 2 shown includes a mounting connection portion 22 connected to the fixed connection member 31, and a second opening is provided at one end of the mounting connection portion 22 close to the fixed connection member 31, and the fixed connection member 31 is detachably connected to the mounting connection portion 22 through the second opening;

[0047] Specifically, the mounting connection part 22 is a steel pipe, the mounting connection part 22 is provided with a second opening, the fixed connection part 31 is inserted into the mounting connection part 22 through the second opening, and the first auxiliary part 21 is welded on the second opening so that the fixed connection part 31 is threadedly connected to the mounting connection part 22.

[0048] Furthermore, a second opening is provided at one end of the installation connection portion 22 near the fixed connection member 31, so that the fixed connection member 31 can be detachably connected to the installation connection portion 22 through the opening, which is conducive to facilitating the installation and disassembly process of the installation mechanism 2 and the driving mechanism 4, simplifying the operation steps, and improving the convenience and efficiency of the operation.

[0049] like Figure 1 The fixed connector 31 shown includes a first fixed connector 311, a second fixed connector 312 symmetrically arranged with the first fixed connector 311, a third fixed connector 313, and a fourth fixed connector 314 symmetrically arranged with the third fixed connector 313. The first fixed connector 311, the second fixed connector 312, the third fixed connector 313 and the fourth fixed connector 314 are all detachably connected to the mounting mechanism 2.

[0050] Furthermore, the movable connector 32 includes a first movable connector 321 connected to the first fixed connector 311 , a second movable connector 322 connected to the second fixed connector 312 , a third movable connector 323 connected to the third fixed connector 313 , and a fourth movable connector 324 connected to the fourth fixed connector 314 .

[0051] Furthermore, the mounting mechanism 2 is provided with a plurality of fixed connectors 31 and movable connectors 32. When some of the fixed connectors 31 or movable connectors 32 are damaged and cannot be adjusted, other fixed connectors 31 and movable connectors 32 can still continue to support and reinforce the device, thereby ensuring that the device can still be used normally, which is beneficial to improving the reliability and stability of the device.

[0052] like Figure 1 The cross section of the mounting mechanism 2 shown is in the shape of a cross;

[0053] Furthermore, the inner wall of the box body has four side surfaces, and the "cross"-shaped arrangement enables four sets of driving mechanisms 3 and supporting mechanisms 4 to be installed on the mounting mechanism 2 corresponding to the four side surfaces respectively. The four inner walls of the box body are subjected to force more evenly, effectively supporting the weight and strength of the inner wall of the box body, thereby enhancing the overall stability of the box body.

[0054] Furthermore, by setting up four sets of driving mechanisms 3 and supporting mechanisms 4 to cooperate with each other, the box body can be made more stable when subjected to force. By setting the "cross"-shaped cross section of the mounting mechanism 2, it can be ensured that each inner wall is evenly supported, thereby improving the overall stability of the box body.

[0055] Specifically, as a preferred embodiment of the utility model but not a limitation, the driving mechanism 3 and the supporting mechanism 4 are both 4 groups. When the user needs to adjust the supporting mechanism 4 in the horizontal direction, the supporting mechanism 4 in the vertical direction must be adjusted in advance to abut against the inner wall of the box. With the upper and lower supporting mechanisms 4 abutting against the inner wall of the box, the mounting mechanism 2 is fixed and cannot move. At this time, the user can adjust the driving members 33 on the left and right sides in the horizontal direction. Since the mounting mechanism 2 cannot move, under the action of the horizontal driving member 33, the supporting mechanisms 4 in the horizontal direction on the left and right sides can be close to or away from the inner wall of the box.

[0056] like Figure 1 The cross section of the supporting surface 43 shown is either an "L" shape or a "T" shape;

[0057] Optionally, in some embodiments, the supporting surface 43 includes a first supporting surface and a second supporting surface vertically connected to the first supporting surface, the first supporting surface can support the inner wall of the box, and the second supporting surface can support the bottom plate of the box between the four inner walls, so that the supporting surface 43 is more stable and firm when subjected to vertical or horizontal force, ensuring that it can effectively support the weight and strength of the bottom plate and side walls of the box.

[0058] Optionally, in some other embodiments, the supporting surface 43 includes a first supporting surface, a second supporting surface vertically connected to the first supporting surface, and a third supporting surface vertically connected to the first supporting surface. The first supporting surface can support the inner wall of the box body, and the second supporting surface and the third supporting surface respectively support the bottom plate on both sides of the reinforced inner wall to ensure that they can effectively support the weight and strength of the bottom plate on both sides of the reinforced box body and the inner wall of the box body.

[0059] Furthermore, the setting of the "L"-shaped or "T"-shaped cross-section can improve the stability of the supporting surface 43. By supporting and reinforcing the inner side wall with the first supporting surface and supporting and reinforcing the bottom plate with the second supporting surface, an overall supporting structure is formed, which can effectively disperse the force and avoid deformation or instability of the side wall or the bottom plate, thereby improving the overall stability of the device.

[0060] like Figure 1 The fixed connecting member 31 and the movable connecting member 32 are integrally formed;

[0061] Optionally, in some embodiments, the fixed connection member 31 and the movable connection member 32 are detachably connected.

[0062] Furthermore, as a preferred mode of the present invention but not a limitation, the fixed connector 31 and the movable connector 32 are integrally formed. The integrally formed setting can increase the overall stability of the device. Since the fixed connector 31 and the movable connector 32 are integrated together, a more secure and stable connection method is formed, which reduces the possibility of device instability caused by loosening or falling off of the connector.

[0063] Furthermore, integrally forming the fixed connector 31 and the movable connector 32 can simplify the structural setting. This connection method reduces the number of connection points, improves the structural simplicity and stability of the device, and reduces the complexity of the assembly process, saving manufacturing costs and time.

[0064] Working principle:

[0065] The first auxiliary member 21 is welded to the installation connection part 22, and the second auxiliary member 41 is welded to the support connection part 42. The first thread 11 on the fixed connection part 31 cooperates with the first auxiliary member 21, and the second thread 12 on the movable connection part 32 cooperates with the second auxiliary member 41. The rotation direction of the first thread 11 is opposite to the rotation direction of the second thread 12. When the driving member 33 is rotated, the movable connection part 32 and the fixed connection part 31 rotate at the same time, so that the installation mechanism 2 and the support mechanism 4 move toward or away from the driving member 33 at the same time; when the reinforcement component 1 is placed in the concealed box, the third fixed connection part 313 and the third movable connection part 32 3 is cooperated so that the supporting mechanism 4 supports and reinforces an inner wall of the box, the second fixed connecting member 312 and the second movable connecting member 322 are cooperated so that the supporting mechanism 4 supports and reinforces an inner wall of the box, and the fourth fixed connecting member 314 and the fourth movable connecting member 324 are cooperated so that the supporting mechanism 4 supports and reinforces an inner wall of the box. At this time, the driving member 33 is rotated, and the three directions of the mounting mechanism 2 are respectively against the three surfaces of the inner wall of the box. The friction force generated by the friction makes it impossible for the first fixed connecting member 311 to drive the mounting mechanism 2 to approach or move away from the first movable connecting member 321, and the first movable connecting member 321 can drive the supporting mechanism 4 to move relative to the mounting mechanism 2.

[0066] The implementation method of this embodiment is as follows:

[0067] A reinforcement device for a concealed distribution box comprises a reinforcement component 1 arranged on the concealed distribution box, the reinforcement component 1 comprises a mounting mechanism 2, a driving mechanism 3 and a supporting mechanism 4, the driving mechanism 3 comprises a fixed connecting member 31 connected to the mounting mechanism 2, a movable connecting member 32 connected to the fixed connecting member 31 at one end and connected to the supporting mechanism 4 at the other end, and a driving member 33 located between the fixed connecting member 31 and the movable connecting member 32, the fixed connecting member 31 is provided with a first thread 11, the movable connecting member 32 is provided with a second thread 12 with a rotation direction opposite to the first thread 11, the mounting mechanism 2 is provided with a nut matching with the first thread 11, the supporting mechanism 4 is also provided with a nut matching with the second thread 12, and the fixing member 31 is provided with a first thread 11, and the fixing member 31 is provided with a second thread 12. The fixed connector 31 is threadedly connected to the mounting mechanism 2 through a nut, and the movable connector 32 is threadedly connected to the support mechanism 4 through a nut. When the user rotates the driving member 33, the fixed connector 31 and the movable connector 32 rotate simultaneously. Under the action of the thread, the support mechanism 4 moves relative to the mounting mechanism 2, and the support mechanism 4 can approach or move away from the inner wall of the box, so as to achieve the effect of supporting the inner wall of the box. This effectively solves the problem that the box is easily deformed due to improper reinforcement, thereby leaking and damaging the box, and this method cannot flexibly adjust the size according to the size of the box, which wastes manpower and time costs. At the same time, the cross section of the mounting mechanism 2 is in the shape of a "cross", that is, four sets of driving mechanisms 3 and support mechanisms 4 can be installed on the mounting mechanism 2 to support and reinforce the four inner walls of the box, so that the four inner walls of the box are more evenly stressed, effectively supporting and reinforcing the weight and strength of the inner wall of the box, and enhancing the overall stability of the box.

[0068] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
