[0005] The high-sealing photovoltaic module junction box of this utility model is achieved by the following specific technical means:
[0006] A high-sealing photovoltaic module junction box includes a middle junction box body, a positive junction box body, a negative junction box body, and a mounting base;
[0007] A connecting pad is fixedly installed at the rear end of the middle junction box. The middle junction box, positive junction box, and negative junction box are respectively snapped onto the front end of the mounting base. The front and rear ends of the middle junction box, positive junction box, and negative junction box are identical. Four sets of limiting grooves are opened at the rear end of the middle junction box. A set of pull plates is slidably installed at both ends of the mounting base. Two sets of inserts are fixedly installed at the inner end of the pull plates, and the inserts are respectively inserted into the limiting grooves of the middle junction box. An outer sealing plate is snapped onto the outer end of the middle junction box. A washer is fixed at the inner end of the outer sealing plate. The outer sealing plate has slots at both ends and a rocker groove at the bottom. A set of limiting blocks is slidably installed at both ends of the middle junction box. The limiting blocks at both ends of the middle junction box are respectively inserted into the slots at both ends of the outer sealing plate. A movable base is slidably installed at the bottom of the middle junction box, and a rocker is rotatably installed on the movable base.
[0008] In at least some embodiments, a set of second elastic members are respectively sleeved on the two sets of support rods on the pull plate, and the outer ends of the second elastic members are in contact with the inner end faces of the fixing plates on the mounting base.
[0009] In at least some embodiments, support plates are fixedly installed at both ends of the central junction box, and sliding holes are provided on the support plates. A connecting rod is fixedly installed at the outer end of the limiting block, and the connecting rod at the outer end of the limiting block is slidably installed on the support plates at both ends of the central junction box.
[0010] In at least some embodiments, two sets of fixing plates are fixedly installed at both ends of the mounting base, and sliding holes are provided on the fixing plates. Two sets of support rods are fixedly installed on the pull plate, and the two sets of support rods on the pull plate are slidably installed on the fixing plates at both ends of the mounting base.
[0011] In at least some embodiments, a set of first elastic members are respectively sleeved on the connecting rod at the outer end of the limiting block, and the outer ends of the first elastic members are respectively in contact with the inner end face of the support plate on the middle junction box.
[0012] In at least some embodiments, a guide groove is provided at the front end of the central junction box, and guide blocks are fixedly installed at both ends of the movable seat, with the guide blocks at both ends of the movable seat slidably installed on the guide groove at the front end of the central junction box.

[0014] Compared with the prior art, the high-sealing photovoltaic module junction box of this utility model has the following beneficial effects:
[0015] 1. The pull plate design facilitates the sliding installation of two sets of support rods on the pull plate onto the fixed plates at both ends of the mounting base. Pulling the pull plate outwards engages the positioning blocks at the rear end of the central junction box with the positioning slots at both ends of the mounting base. Once the central junction box has moved to the fixed position, releasing the pull plate causes it to move inwards under the action of the second elastic element on the support rod. The insert blocks then engage with the limiting slots of the central junction box, making the device easy and quick to assemble and disassemble, thus improving the installation efficiency.
[0016] 2. The setting of the limiting block facilitates the sliding installation of the connecting rod at the outer end of the limiting block onto the support plates at both ends of the central junction box. Pulling the limiting block outwards engages the outer sealing plate with the outer end of the central junction box. After the outer sealing plate moves to a fixed position, the limiting block is released. Under the action of the first elastic element on the connecting rod, the limiting blocks at both ends of the central junction box are respectively inserted into the slots at both ends of the outer sealing plate. With the cooperation of the inner end washer of the outer sealing plate, the device has a better sealing connection effect. The guide blocks at both ends of the moving seat are respectively slidably installed on the guide groove at the front end of the central junction box. Pushing the moving seat upwards inserts the rocker arm into the rocker groove at the bottom of the outer sealing plate. Pressing the rocker arm causes the inner end of the rocker arm to lift the outer sealing plate, making the outer sealing plate easy to disassemble and improving the maintenance efficiency of the device.
