[ detailed description ] embodiments

The dynamic beacon guard box of the present invention is described in further detail below with reference to specific embodiments.

As shown in fig. 1, 2, 3, and 4, the dynamic beacon protection box generally includes a hollow box body 1 and an upper cover 2, which are matched with each other, a beacon 3, a terminal strip 4, and a PCB 5 are disposed in the box body 1, an inner box 6 protruding from the bottom surface of the box body 1 is disposed inside the box body 1, a cover plate 7 is disposed on the inner box 6, the PCB 5 is disposed in the inner box 6, and a waterproof joint 8 is disposed on a side wall of the inner box 6.

Preferably, as shown in fig. 2 and 4, a mounting seat 9 protruding from the bottom surface of the case 1 is provided in the case 1, and the terminal strip 4 is provided on the mounting seat 9. The mounting height of the terminal block 4 is raised by the arrangement of the mounting seat 9.

Preferably, as shown in fig. 2 and 4, two sides of the box body 1 protrude to form a platform 10, and two sides of the beacon 3 are erected on the platform 10. The installation height of the beacon 3 is raised by the platform 10.

As shown in fig. 2, the connection structure between the box body 1 and the upper cover 2 is as follows: the periphery of the box body 1 is a box wall 11 with a certain width, a fully-enclosed water retaining strip 12 is arranged on the inner edge of the top surface of the box wall 11 along the circumferential direction, the water retaining strip 12 protrudes out of the top surface of the box wall 11, a fully-enclosed groove 13 is arranged on the outer side of the water retaining strip 12 along the circumferential direction, a sealing strip is arranged in the groove 13, the upper cover 2 is matched with the box body 1 and is connected with the box wall 11 through a plurality of screws 14 penetrating through the top wall of the upper cover 2, and the water retaining strip 12 is attached to the inner side surface of the upper cover 2 after being covered. The water bar 12 is of a polygonal structure and is in smooth transition at the corners. This

box body

1 and 2 connection structure of upper cover have quadruple waterproof function: 1. firstly, the wide and thick box wall 11 is matched with the upper cover 2, so that water vapor is not easy to enter from a gap between the box body 1 and the upper cover 2. 2. By the design of the sealing strip, the sealing performance is further improved. 3. Through the design of the water retaining strip 12, moisture passing over the sealing strip is not easy to enter the box body 1. 4. The design of the water bar 12 with the polygonal structure is matched with the smooth transition corners, so that no water gathering point exists in the whole water bar 12, and water vapor is not easy to cross the water bar 12 and enter the box body 1.
