DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 6 A protective device for indoor weak current installation includes a box body 1, an outer wall of the box body 1 is provided with evenly distributed heat dissipation ports 2, and a baffle 3 is provided above the heat dissipation ports 2. A circuit board 4 is fixedly connected to the inner wall of the box body 1, and a rotating shaft 5 is rotatably connected to the inner wall of the box body 1. The rotating shaft 5 is connected to a rolling shutter door 6 through a rolling door structure, and a mounting block 7 is fixedly connected to the outer wall of the back side of the box body 1, and the mounting block 7 is connected to a connecting plate 8 through a limiting structure.

[0025] Furthermore, the heat dissipation opening 2 is in an inclined shape with a lower outer end, and the baffle 3 is located above the heat dissipation opening 2 outside the box body 1 .

[0026] The outward end of the heat dissipation port 2 is located at a low position, which can help dissipate heat while preventing a large amount of water and dust from entering the box body 1.

[0027] Furthermore, the rolling door structure includes a symmetrically distributed rotating ring 9, a sliding rail 10, and a limiting rod 11, the rotating ring 9 is fixedly connected to the rotating shaft 5, the sliding rail 10 is fixedly connected to the inner wall of the box body 1, the rolling door 6 is slidably connected to the sliding rail 10, and the limiting rod 11 is slidably connected to the outer wall of the box body 1.

[0028] Among them, one end of the rolling door 6 is fixedly connected to the outer wall of the rotating ring 9, and the other end is provided with a blocking bar, so that the rolling door 6 can be restricted when it moves to the top and will not fall off the slide rail 10.

[0029] Furthermore, the limiting structure includes a sleeve 12, a limiting hole 13, a limiting groove 14, an L-shaped mounting block 15, an auxiliary block 16, a sliding hole 17, a spring 18, and a protrusion 19. The sleeve 12 is fixedly connected to the outer wall of the mounting block 7, the limiting hole 13 is arranged on both sides of the outer wall of the sleeve 12, the limiting groove 14 is arranged at the bottom of the outer walls on both sides of the mounting block 7, and the auxiliary block 16 is fixedly connected to the connecting plate 8.

[0030] The opening of the sleeve 12 faces downward, and the opening of the limiting groove 14 also faces downward, so that when the box body 1 is installed, it only needs to be aligned with the position and installed from top to bottom.

[0031] Furthermore, the sliding hole 17 is arranged on the outer wall of the mounting block 15 , one end of the spring 18 is fixedly connected to the inner wall of the sliding hole 17 , the other end of the spring 18 is fixedly connected to the protrusion 19 , and the protrusion 19 is slidably connected to the sliding hole 17 .

[0032] When the projection 19 enters the sliding hole 17 under the action of the spring 18 , the spring 18 is compressed. At the same time, under the elastic force of the spring 18 , the projection 19 returns to its original position after losing the restriction, thereby achieving the restriction on the box body 1 .

[0033] Furthermore, the mounting block 15 is slidably connected to the inner wall of the sleeve 12 , the position of the protrusion 19 is matched with the limiting hole 13 , and the auxiliary block 16 is matched with the limiting groove 14 .

[0034] Among them, through the above-mentioned mutually adapted structure, when the box body 1 is connected to the connecting plate 8, the bottom can be supported by the installation block 15 and the auxiliary block 16 on the connecting plate 8, thereby enhancing the stability of the box body 1.

[0035] Working principle: First, to open the rolling shutter door 6, you need to pull out the limit rod 11 first, and then manually push the rolling shutter door 6 to move upward. The rolling shutter door 6 drives the rotating ring 9 to rotate, and the rotating ring 9 drives the rotating shaft 5 to rotate, so that the rolling shutter door 6 can be collected and rolled on the rotating shaft 5. To close the rolling shutter door 6, you only need to move the rolling shutter door 6 downward as described above, move it to the bottom and then insert the limit rod 9.

[0036] When installing the box body 1, it is necessary to align the sleeve 12 with the position of the installation block 15, and the limiting groove 14 also needs to be aligned with the position of the auxiliary block 16. Press from top to bottom to install it. At this time, the protrusion 19 is squeezed by the inner wall of the sleeve 12 and enters the sliding hole 17. After reaching the position of the limiting hole 13, the protrusion 19 returns to its original position under the elastic force of the spring 18, and the sleeve 12 is restricted. When disassembling the box body 1, you only need to press the protrusion 19 first, and then take the sleeve 12 out of the installation block 15 upwards.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
