Figure 2 This is a schematic diagram of the retracted structure of a mobile temporary cable head junction box provided in an embodiment of this utility model;

[0060] like Figure 1 and Figure 2 As shown, the adapter box includes an adapter box body 100, a rotation adjustment mechanism 300, and a support frame 200; wherein the adapter box body 100 is provided with a power adapter 110, the adapter box body 100 is connected to the support frame 200 through the rotation adjustment mechanism 300, and the adapter box body 100 can be rotated to the inside or outside of the support frame 200 through the rotation adjustment mechanism 300.

[0061] The support frame 200 includes two support frames 210 fixed to each other; the rotation adjustment mechanism 300 includes a rotating shaft 310, an arc-shaped rack 320, a drive gear 330, and a drive motor 340; wherein, the rotating shaft 310 is movably connected between the two support frames 210, the arc-shaped rack 320 is fixed on the inner wall of the support frame 210, and the center of the arc-shaped rack 320 is located on the rotating shaft 310; the arc-shaped rack 320 meshes with the drive gear 330, and the drive gear 330 is driven by the drive motor 340; both the rotating shaft 310 and the drive motor 340 are fixed to the bottom of the adapter box body 100.

[0062] Specifically, the adapter box body 100 is equipped with electrical devices for branching, switching or other cable connections; the power adapter 110 is installed on the front panel and / or rear panel of the adapter box body 100, and can be installed on one or both sides; the two sides of the adapter box body 100 are connected between two support frames 210 via a rotating shaft 310.

[0063] Specifically, one end of the rotating shaft 310 is movably connected to the inner wall of one support frame 210; the other end of the rotating shaft 310 is movably connected to the inner wall of another support frame 210, allowing the rotating shaft 310 to rotate between the two support frames 210. The two support frames 210 are relatively fixed, and to ensure stability between them, they can be fixed together by a fixing rod. The fixing rod is fixed between the two support frames 210 and does not affect the rotational position of the adapter box body 100.

[0064] Specifically, the rotating shaft 310 is fixed to the bottom of the adapter box body 100. In one embodiment, the rotating shaft 310 can be directly fixed to the bottom outer surface of the adapter box body 100. In another embodiment, the rotating shaft 310 can be inserted into the adapter box body 100 and fixed to the adapter box body 100.

[0065] This embodiment provides a mobile temporary cable head junction box. The junction box body 100 can be rotated to the inside or outside of a support frame 200 via a rotation adjustment mechanism 300. The support frame 200 includes two support frames 210 fixed to each other. The rotation adjustment mechanism 300 includes a rotating shaft 310, an arc-shaped rack 320, a drive gear 330, and a drive motor 340. The rotating shaft 310 is movably connected between the two support frames 210. The arc-shaped rack 320 is fixed to the inner wall of the support frame 210, and its center is located on the rotating shaft 310. The arc-shaped rack 320 meshes with the drive gear 330, which is driven by the drive motor 340. Both the rotating shaft 310 and the drive motor 340 are fixed to the bottom of the junction box body 100. The following technical effects can be achieved:

[0066] In this embodiment, the extension and retraction of the adapter box body 100 can be achieved by rotating the rotation adjustment mechanism 300. Figure 1 The diagram shows the external structure of the adapter box body 100, which is rotated by the rotation adjustment mechanism 300 to rotate the two support frames 210. Figure 2The diagram shows the structure of the adapter box body 100 rotating inside the two support frames 210 via the rotation adjustment mechanism 300. At this point, the adapter box is at its smallest size, making it easy to transport and move. In addition, through the meshing between the arc-shaped rack 320 and the drive gear 330, the drive gear 330 can stop at any position on the arc-shaped rack 320, thereby driving the adapter box body 100 to rotate via the rotating shaft 310. This allows the adapter box body 100 to rotate and stop at any angle, facilitating the connection of cable heads.

[0067] Figure 3 This is a schematic diagram of the rotation adjustment mechanism, support frame, and height adjustment mechanism provided in this embodiment of the utility model; Figure 4 This is provided by the embodiment of the present utility model. Figure 1 A partial enlarged view of point A in the middle;

[0068] like Figure 3 and Figure 4 As shown, the rotary adjustment mechanism 300 also includes a coupling 350 and a bearing housing 360. The drive motor 340 is coaxially connected to the connecting shaft 370 of the drive gear 330 through the coupling 350. The connecting shaft 370 is fixed on the adapter box body 100 through the bearing housing 360. The coupling 350 enables the connection and disconnection of the drive motor 340 and the connecting shaft 370.

[0069] Specifically, the connecting shaft 370 is sleeved inside the bearing housing 360, and the bearing housing 360 is fixed on the adapter box body 100. When the drive motor 340 is connected to the connecting shaft 370, the drive motor 340 controls the drive gear 330 to rotate, thereby moving the arc rack 320. As a result, the adapter box body 100 rotates through the rotating shaft 310, so that the adapter box body 100 can rotate and stop at any angle, which is convenient for the transfer of cable heads.

[0070] When the drive motor 340 is disconnected from the connecting shaft 370, the position of the adapter box body 100 relative to the drive gear 330 is fixed through the bearing seat 360. The adapter box body 100 can be rotated manually. When the adapter box body 100 rotates, it drives the drive gear 330 to move on the arc rack 320. Through the meshing structure of the drive gear 330 and the arc rack 320, the adapter box body 100 can also be positioned at any angle during the rotation process.

[0075] Specifically, the support frame 210 includes two support rods, which are hollow. A telescopic mechanism 410 is installed in the support rods, and one end of the threaded rod 411 is fixed to the top of the side support rod. The threaded rods 411 in the two support rods of the support frame 210 are connected by a synchronization mechanism 420, which enables the synchronous rotation of the two threaded rods 411. A rotating handle 430 is provided on the top of one of the support rods, and the rotating handle 430 is coaxially fixed with the threaded rod 411.

[0076] Specifically, each support frame 210 includes two support rods, each support rod is hollow, and each support rod is connected to a telescopic mechanism 410 in the manner described above. That is, each support frame 210 has two telescopic mechanisms 410 connected to it. The two threaded rods 411 in each support frame 210 are connected to each other through a synchronization mechanism 420. The synchronization mechanism 420 enables the two threaded rods 411 in the support frame 210 to rotate synchronously, thereby achieving synchronous extension and retraction. The threaded rods 411 complete the extension and retraction of the telescopic mechanism 410 by rotating the threaded tube 412 in either the forward or reverse direction.

[0077] Specifically, each support frame 210 is connected to a rotating handle. By manually rotating the handle, one of the threaded rods 411 can be rotated. Through the synchronization structure, both threaded rods 411 can be rotated synchronously, thereby realizing the extension and tightening of the two telescopic mechanisms 410 on the support frame 210.

[0078] Furthermore, the synchronization mechanism 420 includes a first sprocket 421, a second sprocket 422, and a chain 423. The first sprocket 421 and the second sprocket 422 are connected by the chain 423. The first sprocket 421 is coaxially fixed with a threaded rod 411, and the second sprocket 422 is coaxially fixed with another threaded rod 411.

[0079] Specifically, one end of the chain 423 engages with the first sprocket 421, and the other end of the chain 423 engages with the second sprocket 422;

[0082] like Figures 6-8 As shown, the power adapter 110 is disposed on the front panel and / or rear panel of the adapter box body 100, and the two sides of the adapter box body 100 are sandwiched between two support frames 210; the adapter box also includes an adapter frame 500, which is connected to the side of the adapter box body 100 on which the power adapter 110 is disposed; the adapter frame 500 includes a pressure outer frame 510, a pressure bolt 520, a pressure nut 530, a mounting plate 540, and an adjustment structure 550;

[0083] Specifically, a pressure nut 530 is fixed on the pressure frame 510. The pressure frame 510 is connected to the adapter box body 100 by the cooperation of the pressure bolt 520 and the pressure nut 530. The pressure frame 510 can be pushed towards or pulled away from the adapter box body 100 by the cooperation of the pressure bolt 520 and the pressure nut 530. A mounting plate 540 is connected to the pressure frame 510. The mounting plate 540 has an adapter hole 541, which corresponds to the power adapter 110.

[0084] Furthermore, the adapter hole 541 is provided with a clamping component, which can clamp the cable head by opening and closing with a spring.

[0085] Furthermore, the power adapters 110 are arranged in multiple rows evenly on the panel, and the adapter holes 541 are arranged in rows on the mounting plate 540. The number of mounting plates 540 is set according to the number of rows of the power adapters 110, and the adapter holes 541 are set one-to-one with the power adapters 110.

[0086] As one embodiment, pressure nuts 530 are fixed at the top and bottom of the pressure frame 510, and threaded holes are opened on the adapter box body 100. Tightening and loosening the pressure bolt 520 on the threaded holes can push the pressure frame 510 towards or away from the adapter box body 100.

[0087] Specifically, the adjustment structure 550 is used to adjust the position of the mounting plate 540, specifically to adjust the vertical position of the mounting plate 540;

[0088] Specifically, the adjustment structure 550 includes a clamping screw 551, a driven bevel gear 552, and an adjusting bevel gear 553; the clamping screw 551 is movably connected to the side of the pressure frame 510, the driven bevel gear 552 is coaxially fixed with the clamping screw 551, and the driven bevel gear 552 meshes with the adjusting bevel gear 553; one end of the mounting plate 540 is fixed to the clamping screw 551.

[0089] Furthermore, the clamping screw 551 is a bidirectional clamping screw;

[0090] Furthermore, one end of the mounting plate 540 is fixed to the clamping screw 551, and the other end has a limit hole, through which it is sleeved onto the limit rod; the clamping screw 551 is located on one side of the pressure frame 510, and the limit rod is fixed on the other side of the pressure frame 510.

[0091] Furthermore, an outer door panel 700 is fixed to the surface of the pressure frame 510. One side of the outer door panel 700 is movably connected to the pressure frame 510. The outer door panel 700 can be opened and closed, and when closed, it covers the surface of the pressure frame 510 to prevent dust.

[0092] Specifically, when using the adapter box provided in this embodiment, the pressure frame 510 is pulled back, the cable head is snapped into the adapter hole 541, the position of the adapter hole 541 is accurately positioned by adjusting the position of the mounting plate 540 up and down, and then the pressure frame 510 is pushed in by the pressure bolt 520 to realize the connection between the cable head and the power adapter 110. This enables non-contact and precise positioning, further ensuring the safety of the staff.

[0093] This embodiment provides a mobile temporary cable head junction box, which can achieve the following technical effects:

[0094] The embodiments of this application can extend and retract the adapter box body by rotating the adjustment mechanism. Through the meshing between the arc-shaped rack and the drive gear, the drive gear can stop at any position on the arc-shaped rack, thereby driving the adapter box body to rotate through the rotating shaft, so that the adapter box body can rotate and stop at any angle, which is convenient for cable head connection. After the adapter box body is retracted into the support frame, it is compact in size and easy to move and carry.

[0095] In this embodiment, the coupling enables the connection and disconnection of the drive motor and the connecting shaft. When the drive motor is connected to the connecting shaft, the drive motor controls the drive gear to rotate, thereby moving the arc-shaped rack. This allows the adapter box body to rotate via the rotating shaft, enabling the adapter box body to rotate and stop at any angle. When the drive motor is disconnected from the connecting shaft, the adapter box body is relatively fixed to the drive gear via the bearing seat. It can be rotated manually. Through the meshing structure of the drive gear and the arc-shaped rack, the adapter box body can also be positioned at any angle during the rotation process before starting work.

[0096] In this embodiment, each support frame is connected to two telescopic mechanisms. The two threaded rods in each support frame are interconnected by a synchronization mechanism, which enables the two threaded rods in the support frame to rotate synchronously, thereby achieving synchronous extension and retraction. The threaded rods rotate in the forward or reverse direction of the threaded tube to complete the extension and retraction of the telescopic mechanism, realizing the height adjustment of the adapter box body and meeting various height requirements.

[0097] In this embodiment, a pressure nut is fixed to the outer pressure frame. The outer pressure frame is connected to the adapter box body via pressure bolts and the pressure nut. The pressure bolts and the pressure nut allow the outer pressure frame to be pushed towards or pulled away from the adapter box body. A mounting plate is connected to the outer pressure frame. The vertical position of the mounting plate can be adjusted by adjusting the structure. An adapter hole is provided on the mounting plate. In use, the outer pressure frame is pulled away, and the cable head is inserted into the adapter hole. By adjusting the position of the mounting plate, the position of the adapter hole is precisely located. Then, the pressure bolts are used to push the outer pressure frame forward to connect the cable head to the power adapter. This enables non-contact and precise positioning, further ensuring the safety of the personnel.

[0098] In summary, the temporary junction box provided in this application embodiment can quickly locate and fix the position of the cable head, and through the pressure frame, it can be electrically connected to the temporary transfer electrical appliance, thereby improving the cable transfer efficiency. By rotating the support frame and the height adjustment mechanism, the usage height of the device can be quickly adjusted, improving the device's adaptability to the external environment and increasing the flexibility of the device during use.
