[0025] As a technical optimization scheme of the utility model, by setting an adjustment component 10, when the user places warning signs 8 of different heights, the moving block 102 is first moved toward the inner side of the fixed rail 101, and the moving block 102 can be used to drive the limit rod 104 to move. At this time, the limit rod 104 moves out of the limit groove 103, and then the first placement plate 5 is adjusted to a position suitable for the height of the warning sign 8, and then the moving block 102 is moved toward the outside of the fixed rail 101, so that the limit rod 104 moves to the inside of the limit groove 103, and the limit groove 103 can be used to limit the up and down movement of the limit rod 104, so that the first placement plate 5 stays here, thereby achieving the effect of adjusting the distance between the first placement plate 5 and the second placement plate 6.

[0027] As a technical optimization scheme of the utility model, by setting a reinforcement component 11, when the user places the warning sign 8, the user aligns the screw 111 with the thread groove 112, and then rotates the screw 111 to move the screw 111 to the inside of the thread groove 112. The screw 111 is moved toward the warning sign 8 to tighten the warning sign 8. The hand wheel 113 can be used to increase the contact area between the user and the screw 111, making it easier for the user to rotate the screw 111, thereby achieving the effect of reinforcing the warning sign 8.

[0032] refer to Figure 2 A light / darkness detector 16 is fixedly connected to the front side of the bottom of the top cover 4 , and the light / darkness detector 16 is electrically connected to the control panel 9 through a wire.

[0033] As a technical optimization scheme of the utility model, by setting a light and darkness detector 16, when the user does not have time to control the turning on of each lamp 15, the light and darkness detector 16 can be used to detect the brightness of the area where the transformer box is located in real time. When the brightness of the area where the transformer box is located is lower than the set threshold, the light and darkness detector 16 will transmit an electrical signal to the control panel 9 to turn on the lamp 15. When the brightness of the area where the transformer box is located is lower than the set threshold, the light and darkness detector 16 will transmit an electrical signal to the control panel 9 to turn off the lamp 15. The control panel 9 can then be used to control the switch of the lamp 15, thereby achieving the effect of automatically turning on the lamp 15.

[0034] refer to Figure 3 The top of the moving block 102 is fixedly connected with an auxiliary bar 17, and the auxiliary bars 17 are provided in a number and are distributed at equal distances.

[0036] The working principle and use process of the utility model are as follows: the first placement plate 5 and the second placement plate 6 can be used to facilitate the user to place the warning sign 8 on both sides of the box body 3. When the user places warning signs 8 of different heights, the moving block 102 is first moved toward the inner side of the fixed rail 101, and the moving block 102 can be used to drive the limiting rod 104 to move. At this time, the limiting rod 104 moves out of the limiting groove 103, and then the first placement plate 5 is adjusted to a position suitable for the height of the warning sign 8, and then the moving block 102 is moved toward the outer side of the fixed rail 101, so that the limiting rod 104 moves to the inside of the limiting groove 103, and the limiting groove 103 can be used to limit the upward and downward movement of the limiting rod 104, so that the first placement plate 5 stays there. When the user has placed the warning sign 8, the user aligns the screw 111 with the thread groove 112, and then rotates the screw 111 to move the screw 111 to the inside of the thread groove 112, and uses the screw 111 to move toward the direction of the warning sign 8 to press the warning sign 8 tightly, and then use The hand wheel 113 can be used to increase the contact area between the user and the screw 111. When the screw 111 slowly moves toward the warning sign 8, the screw 111 will drive the bottom plate to move. The bottom plate can be used to increase the contact area between the screw 111 and the warning sign 8, which can make the installation of the billboard more stable. The pressure bearing 12 can be used to prevent the screw 111 from driving the abutment plate 13 to rotate, thereby enhancing the tightness of the abutment plate 13. When the user does not have time to control the opening of each lamp 15, the light and darkness detector 16 can be used to detect the brightness of the area where the transformer box is located in real time. When the brightness of the area where the transformer box is located is lower than the set threshold, the light and darkness detector 16 will transmit an electrical signal to the control panel 9 to turn on the lamp 15. When the brightness of the area where the transformer box is located is highly lower than the set threshold, the light and darkness detector 16 will transmit an electrical signal to the control panel 9 to turn off the lamp 15. The control panel 9 can then be used to control the switch of the lamp 15, thereby achieving an enhanced prompting effect.

[0037] To sum up: the preinstalled outdoor transformer box, by providing a first placement plate 5, a second placement plate 6 and a block 7, can facilitate users to place warning signs 8 on both sides of the box body 3 by using the first placement plate 5 and the second placement plate 6, and then the block 7 can prevent the warning sign 8 from automatically detaching from the box body 3, thereby solving the problem that although the transformer box is easy for users to move, the transformer box cover is not provided with a warning device, which makes it easy for the transformer box to fail to remind pedestrians that it is dangerous at night, which can easily increase the risk of the transformer box at night, thereby reducing the service life of the transformer box.
