[0029] The following is combined with Figure 1-5 The utility model is described in further detail.

[0030] The embodiment of the utility model discloses an elevator machine room power supply box structure which is convenient for heat dissipation.

[0031] Reference Figure 1 and Figure 2 A power box structure for an elevator machine room that is convenient for heat dissipation includes a fixed plate 1, a power box 2 is fixedly connected to the outside of the fixed plate 1, a box door 3 is hinged on the outside of the opening of the power box 2, an electronic component 4 is fixedly connected to the inside of the power box 2, a filtering mechanism is provided on the top of the power box 2, and a dehumidification mechanism is provided on the inside of the power box 2.

[0032] When installing the power box 2, first use bolts to firmly connect the power box 2 to the fixed plate 1, then according to the electrical schematic, introduce the elevator's accompanying cables and other related lines into the power box 2, and then use appropriate terminal blocks or connectors to correctly connect the lines to the electronic components 4 in the power box 2, thereby completing the installation of the power box 2. The external air can be filtered through the filtering mechanism to reduce the risk of dust entering the power box 2, and the moisture removal mechanism can adsorb moisture in the air to ensure the stable operation of the power box 2.

[0033] Reference Figure 1 、 Figure 3 and Figure 4 The filtering mechanism includes a ventilation box 5 fixed on the top of the power box 2. The ventilation box 5 is arranged to be hollow. The power box 2 is connected to the ventilation box 5. A filter plate 6 is slidingly arranged on the inner side of the ventilation box 5. One end of the filter plate 6 passes through the ventilation box 5 and is fixedly connected to a handle 7. The end of the filter plate 6 away from the handle 7 passes through the ventilation box 5 and is fixedly connected to an insertion block 8. A snap-fitting part is arranged on the outside of the ventilation box 5.

[0034] Among them, the locking part includes a locking seat 9 fixedly connected to the outside of the ventilation box 5, a placement groove is provided on the inner side of the locking seat 9, a spring 10 is fixedly connected to the inner bottom wall of the placement groove, the top of the spring 10 is fixedly connected to the movable plate 11, the top of the movable plate 11 is fixedly connected to the locking block 12, and a locking groove 13 is provided at the bottom of the insertion block 8, the locking block 12 is locked and connected with the locking groove 13, the locking block 12 and the locking groove 13 are both set to triangles, and the contact surface between the insertion block 8 and the locking block 12 is set to an inclined surface.

[0035] In addition, sliders are fixedly connected to both sides of the movable plate 11 , and sliding grooves 14 are symmetrically opened on the inner walls of both sides of the placement groove, and the sliders are slidably connected to the sliding grooves 14 .

[0036] When filtering dust, first use the handle 7 to insert the filter plate 6 into the ventilation box 5. At this time, the insertion block 8 moves in the ventilation box 5. When it moves to a suitable position, the filter plate 6 is located inside the ventilation box 5. The filter plate 6 can filter the air, which can effectively reduce the risk of dust entering the power box 2.

[0037] When the filter plate 6 moves in the ventilation box 5, the insertion block 8 enters the locking seat 9. At this time, the insertion block 8 will contact the locking block 12.
