[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 Please refer to Figures 1-6 As shown, a pre-embedded distribution box includes a box body 1, an openable door 2 on the front side of the box body 1, wire holes 3 on the top and bottom of the box body 1, two mounting brackets 6 inside the box body 1, two corner blocks 4 symmetrically installed on both sides of the box body 1, and mounting holes on each corner block 4. It also includes an adjustment component 7 for adjusting the two mounting brackets 6. The adjustment component 7 includes a horizontal adjustment component for moving the two mounting brackets 6 along the width direction of the box body 1. The horizontal adjustment component includes a movable plate 71. The movable plate 71 is connected to a driving component that drives it to move along the inside of the box body 1. The two mounting brackets 6 are both set on the side wall of the movable plate 71.

[0020] Specifically, regarding the aforementioned driving components, such as Figures 2-4 As shown, the driving component includes a fixing block 73 mounted on the inner wall of the housing 1. An adjusting screw 72 is rotatably mounted between the fixing block 73 and the inner wall of the housing 1, and a rotating disc is mounted on one end of the adjusting screw 72.

[0021] As described above, when in use, the box 1 can be placed into the reserved groove on the wall, and the cable can be threaded into the box 1 through the wire hole 3. Then, the box 1 can be installed and fixed by the corner block 4. After that, the electrical components can be installed on the two mounting brackets 6 and wired. Then, the box door 2 can be closed for power distribution. Meanwhile, when installing electrical components on the mounting bracket 6, the adjusting screw 72 can be rotated by turning the rotary dial, causing the adjusting screw 72 to move the movable plate 71 along the inside of the enclosure 1 until the movable plate 71 moves the mounting bracket 6 out of the enclosure 1. Then, the installer installs the electrical components onto the mounting bracket 6. After installation, the adjusting screw 72 can be rotated in the opposite direction by turning the rotary dial, causing the adjusting screw 72 to move the movable plate 71 into the enclosure 1. At this time, the movable plate 71 moves the mounting bracket 6 and the electrical components installed on it into the enclosure 1 simultaneously, which facilitates the installation of electrical components and avoids the problem of inconvenient installation due to the small internal space of the enclosure 1. This facilitates the rapid installation of electrical components and makes the use of the distribution box more convenient.

[0022] Furthermore, in this embodiment, to ensure the stable movement of the movable plate 71, such as... Figures 2-5 As shown, the top and bottom of the movable plate 71 are provided with sliding grooves, and the inner wall of the box 1 is equipped with guide rails that cooperate with the sliding grooves.

[0023] Specifically, when the movable plate 71 is driven to move along the inside of the housing 1 by adjusting the screw 72, the movable plate 71 can move along the guide rail through the slide groove to limit the movement of the movable plate 71, thereby facilitating the stable movement of the movable plate 71 and benefiting the stable adjustment of the mounting frame 6.

[0024] Example 2 Based on Example 1, and referring to Figures 4-7 As shown, the adjusting component 7 also includes a vertical adjusting component for adjusting the distance between the two mounting brackets 6. The vertical adjusting component includes a clip 76 installed on the back side of the two mounting brackets 6 and a plurality of slots 74 opened on the front side of the movable plate 71 and evenly distributed along the height direction of the movable plate 71. The movable plate 71 is also provided with a limiting component for limiting and fixing the clip 76.

[0025] Specifically, the limiting component includes a pin 75 that can be detachably inserted into both sides of the movable plate 71. One end of the pin 75 is equipped with a handle, and both ends of the locking strip 76 are provided with pin holes that cooperate with the pin 75.

[0026] When installing electrical components, the spacing between the two mounting brackets 6 can be adjusted according to the specifications of the electrical components, and the specific adjustment steps are as follows: First, pull the pin 75 out of the pin hole using the handle. Then, pull the mounting bracket 6 to pull the retaining strip 76 out of the retaining groove 74. Next, move the mounting bracket 6 up or down so that the distance between the two mounting brackets 6 meets the specifications of the electrical components. Then, insert the retaining strip 76 on one side of the mounting bracket 6 into the corresponding retaining groove 74 to lock the mounting bracket 6 into the movable plate 71. Then, insert the pin 75 into the corresponding pin hole again using the handle to lock the retaining strip 76 in place. This completes the installation and fixing of the mounting bracket 6, thereby enabling quick adjustment of the distance between the two mounting brackets 6. This facilitates the installation of electrical components of different specifications and further improves the convenience of electrical component installation, enabling rapid installation of electrical components.

[0027] Example 3 Based on Example 1, and referring to Figures 2-4 , Figures 8-11 As shown, the interior of the housing 1 is also provided with two symmetrically distributed support components 5, and each support component 5 includes: The longitudinal support includes a top support plate 51, a bottom support plate 52, and a first telescopic member connecting the top support plate 51 and the bottom support plate 52. The first telescopic member is used to adjust the distance between the top support plate 51 and the bottom support plate 52. The first telescopic member includes a first screw cylinder 53 fixed to the bottom of the top support plate 51 and a rotary table 55 rotatably mounted on the top of the bottom support plate 52. A first threaded rod 54 that can be screwed into the first screw cylinder 53 is installed on the rotary table 55. The transverse support includes a side support plate 57, and a second telescopic member is connected between the side support plate 57 and the first telescopic member. The second telescopic member is used to adjust the position of the side support plate 57. The second telescopic member includes a fixing sleeve 58 fitted onto the bottom of the first screw cylinder 53. A second threaded rod 510 is installed on one side of the fixing sleeve 58, and a second screw cylinder 59 that mates with the second threaded rod 510 is rotatably installed on one side of the side support plate 57.

[0028] After the housing 1 is installed into the reserved slot, the two support components 5 can be inserted into the interior of the housing 1 in sequence. Then, the rotating table 55 is rotated, so that the rotating table 55 drives the first threaded rod 54 to rotate. Under the action of the thread, the first threaded rod 54 drives the first screw barrel 53 to move upward. Then, the first screw barrel 53 lifts the top support plate 51 upward until the top support plate 51 abuts against the top of the interior of the housing 1. In this way, the housing 1 is longitudinally supported by the top support plate 51 and the bottom support plate 52. At the same time, the second screw cylinder 59 can be rotated so that the second screw cylinder 59 moves along the second threaded rod 510 and drives the side support plate 57 to move synchronously until the side support plate 57 abuts against the inner wall of the box 1, thereby achieving lateral support for the box 1.

[0029] In summary, the support component 5, composed of longitudinal and transverse support components, in this embodiment has an overall T-shaped structure and is symmetrically arranged on both sides of the interior of the box 1. This not only effectively supports the box 1, ensuring the stability of the box 1 structure and preventing the box 1 from deforming due to external forces such as shear force from the wall, thus ensuring the normal use of the box 1, but also solves the problem that the existing support component 5 occupies a large space, resulting in a smaller interior space of the box 1 and affecting the installation of electrical components. In addition, both the longitudinal and transverse support members in this embodiment adopt a telescopic structure, which can facilitate the overall retraction of the support member 5. On the one hand, it can realize the telescopic adjustment of the support member 5, so that the support member 5 can be used for distribution boxes of different specifications, thereby improving the applicability of the support member 5. On the other hand, it can facilitate the storage of the support member 5, reduce the space occupied by the support member 5, and thus facilitate the orderly storage or carrying of the support member 5, making it convenient for the use of the support member 5.

[0030] Furthermore, such as Figures 2-4 , Figures 8-10 As shown, two telescopic auxiliary support rods 56 are also installed between the top support plate 51 and the bottom support plate 52, and the two auxiliary support rods 56 are symmetrically distributed on both sides of the first threaded rod 54.

[0031] When adjusting the distance between the top support plate 51 and the bottom support plate 52, the auxiliary support rod 56 can extend and retract accordingly to provide auxiliary support between the top support plate 51 and the bottom support plate 52, thereby facilitating the stable adjustment of the top support plate 51 and the bottom support plate 52 and contributing to the stable support of the inside of the housing 1.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
