DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings.

Support legs 3 are installed at the four corners of the bottom of the second housing 2. A moisture-absorbing box 11, communicating with the interior of the second housing 2, is installed at the bottom of the second housing 2. Multiple storage cylinders 9, one end of which is inserted into the side wall of the moisture-absorbing box 11, are threadedly connected. Multiple through holes are opened in the portion of the storage cylinder 9 inside the moisture-absorbing box 11. A desiccant 12 is disposed inside the storage cylinder 9. Through the arrangement of the moisture-absorbing box 11 and the storage cylinders 9, when it is necessary to replace the desiccant 12 inside the storage cylinder 9, the storage cylinder 9 can be unscrewed from the moisture-absorbing box 11 to remove it from the interior of the moisture-absorbing box 11. At this time, the storage cylinder 9 can be opened to replace the desiccant 12 inside. The junction box does not need to be disassembled when replacing the desiccant 12, making it more convenient to use. Both sides of the housing 2 are rotatably mounted with a drive mechanism 5, and multiple hooks 6 are fixedly mounted on the drive mechanism 5. Both sides of the first housing 1 are fixedly mounted with multiple locking blocks 7 that cooperate with the hooks 6 and a locking mechanism 8 for limiting the rotation of the drive mechanism 5. By setting up the drive mechanism 5, hooks 6, locking blocks 7 and locking mechanism 8, when connecting the first housing 1 and the second housing 2, the drive mechanism 5 can drive the multiple hooks 6 to rotate, so that the hooks 6 lock the locking blocks 7 to complete the connection between the first housing 1 and the second housing 2. When it is necessary to disassemble the first housing 1 and the second housing 2, the drive mechanism 5 can be rotated in the opposite direction to make the hooks 6 disengage from the locking blocks 7, which can effectively shorten the installation and disassembly time of the first housing 1 and the second housing 2. Moreover, when the hooks 6 are locked on the locking blocks 7, the locking mechanism 8 will lock the drive mechanism 5, thereby ensuring the stability of the connection between the first housing 1 and the second housing 2.

[0030] As Figure 1 , Figure 2 and Figure 5 indicated, as the preferred technical solution embodiment of the present application, on the basis of the above-mentioned manner, further, the locking mechanism 8 includes the base 801 fixedly connected on the first shell 1, the bottom of the base 801 is provided with a mounting slot, the inside of the mounting slot is slidably mounted with the locking pin 803 of magnetic material, the top of the locking pin 803 is connected with the spring 802 mounted inside the mounting slot, the connecting block 503 and the mounting shaft 501 are both provided with the pin hole matched with the locking pin 803. It should be noted that when the mounting shaft 501 drives the clamping hook 6 to rotate to be clamped on the clamping block 7, the pin holes on the mounting shaft 501 and the connecting block 503 will be aligned with the mounting slot at the bottom of the base 801, at this time, the locking pin 803 will be inserted into the pin hole at the bottom end under the elastic force of the spring 802, thereby completing the locking of the mounting shaft 501, when unlocking, the magnet is used to attract the locking pin 803 on the top of the base 801, so that it is slid to the mounting slot, thereby releasing the locking of the mounting shaft 501.
