Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof structures, and in particular relates to an outdoor waterproof structure of a shielding box. Background Art

[0002] Shielding boxes are commonly used in production testing. They are designed to provide an interference-free testing environment. By using shielding bodies of various shapes such as shells, plates, and sleeves made of conductive or magnetic materials, the electromagnetic capacity is limited to a certain spatial range to suppress radiation interference. The internal structure of this shielding box usually uses materials with high shielding performance to ensure good shielding effect.

[0003] Among them, high humidity environment has a certain impact on metal shielding bodies. Metal is prone to electrochemical corrosion in a humid environment, which may cause rust on the surface of the shielding body, thereby affecting its conductivity and shielding effect. In addition, excessive humidity may also cause the electrical insulation performance of the shielding body to deteriorate, increasing the risk of short circuit. In addition to placing moisture-proof agents or desiccant in the box, the waterproof effect of the outdoor box door of the shielding box is extremely important. Utility Model Content

[0006] The present invention further illustrates that the first drainage portion is provided as an inclined plate, the first drainage portion is made of a waterproof material or the surface of the first drainage portion is coated with a waterproof layer to prevent rust.

[0007] The utility model further describes that a baffle is fixed at the bottom of the first drainage part, and a second drainage part is opened at the bottom of one side of the first drainage part close to the baffle, forming a designated point for water flow outflow, facilitating the integrated outflow processing of the water flow.

[0008] The present invention further illustrates that the bottom surface of the second drainage portion is arranged as an inclined surface.

[0009] The present invention further illustrates that fixing parts are fixedly installed on both sides of the first drainage part to improve the installation stability of the first drainage part.

[0021] The following is a non-limiting detailed description of the technical solution of the present invention in conjunction with preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model provides a technical solution: a shielding box outdoor waterproof structure, including a door panel 1 and a sealing plate 2 connected to the door panel 1, a mounting groove is formed between the door panel 1 and the sealing plate 2, and a waterproof rubber strip 3 is installed inside the mounting groove. The material of the waterproof rubber strip 3 includes but is not limited to PVC (polyvinyl chloride), EVA (ethylene-vinyl acetate copolymer), MVQ (silicone rubber), which is suitable for corresponding application scenarios and at least achieves a certain waterproof effect to prevent a large amount of external water vapor from entering the shielding box through the door panel gap, thereby providing waterproof protection for the interior of the shielding box.

[0023] A first drainage part 4 is fixed on the surface of the door panel 1 located below the waterproof strip 3. The first drainage part 4 is an inclined plate arrangement for drainage. The first drainage part 4 is made of waterproof material or the surface of the first drainage part 4 is coated with a waterproof layer to prevent rust. Under the impact of external water vapor or water flow, the water flow on the surface of the waterproof strip 3 and the local surface of the door panel 1 flows to the upper surface of the first drainage part 4 below under the action of gravity. Under the action of the inclined surface, the water flows downward in an orderly manner.

[0024] Furthermore, a baffle 5 is fixed to the bottom of the first drainage portion 4, and a second drainage portion 10 is provided at the bottom of the first drainage portion 4 close to the baffle 5. The bottom surface of the second drainage portion 10 is also arranged as an inclined surface. The water flows through the guidance of the flow direction of the first drainage portion 4 and the blocking effect of the baffle 5. The water flows to the second drainage portion 10 and flows toward one end through the inclined surface of the second drainage portion 10, forming a designated point outflow of the water, which facilitates the outflow integration processing of the water flow.

[0025] In addition, in order to improve the installation stability of the first drainage part 4 when the door is opened and closed for a long time, fixing parts are fixedly installed on both sides of the first drainage part 4. The fixing parts include a first fixing plate 8 and a second fixing plate 9 fixed between the first fixing plate 8 and the first drainage part 4. The setting of the second fixing plate 9 does not block the second drainage part 10. The first fixing plate 8 is fixed on the door panel 1 and does not hinder the closing of the door.

[0026] refer to Figure 4, limiting blocks 7 are set at the four right angles of the waterproof strip 3, and the limiting blocks 7 are rotatably connected to the fixing pins 6, which are fixed to the door panel 1. After the waterproof strip 3 is installed, the limiting blocks 7 are rotated to fasten, support and limit the side of the waterproof strip 3 close to it. When the waterproof strip 3 needs to be replaced, it is only necessary to rotate the limiting block 7 angle and then replace the waterproof strip 3. After the replacement is completed, the waterproof strip 3 is limited again to strengthen the fastening of the waterproof strip 3, improve the tightness between the waterproof strip 3 and the door panel seam, and improve the waterproof effect.
