[0002] Currently, in all walks of life, metal box shell structures are often used to carry and protect electronic components and other parts, so that each part can be integrated into the box shell, which is convenient for overall installation, use and transportation.

[0003] In the prior art, in some areas or environments with a large temperature difference between day and night, condensed water is easily generated inside the metal box shell. If the condensed water cannot be discharged for a long time and continues to accumulate in the box shell, it will cause the inner wall of the metal box shell to rust, affecting the service life. At the same time, it is also easy to cause a short circuit in the internal electronic components, affecting the safety of use. Therefore, the box shell used in areas or environments with a large temperature difference between day and night generally needs to be equipped with a leak hole to discharge and clean the condensed water;

[0004] However, in actual use, it is found that although the leakage hole on the box shell can discharge condensed water and facilitate the cleaning of the condensed water inside the box shell, it will also cause external dust or steam to easily enter the box shell from the leakage hole, causing pollution to the inside of the box shell. The current box shell does not have a structure to prevent water leakage from the leakage hole and to prevent dust and water, resulting in the inability to effectively discharge and clean condensed water and to prevent dust and water from the box shell. For this reason, a pressable dust and water valve is proposed. Summary of the invention

[0029] Embodiment 1, as Figure 1-Figure 4As shown, the dustproof and waterproof valve includes a main body 100, a cap 200, an inner pin 300 and a connecting assembly. The main body 100 is a hollow body connected at both ends. A sealing pipe plug is fixedly connected to the side of the main body 100 away from the cap 200. The sealing pipe plug on one side of the main body 100 is inserted into the leakage hole on the outer shell of the box body to block the position of the leakage hole, so that the condensed water in the outer shell of the box body can be discharged along the sealing pipe plug and the middle through hole of the main body 100, so that the leakage of the main body 100 and the outer shell of the box body can be prevented from leaking. Secondly, the inner pin 300 is arranged on one side of the main body 100, and the inner pin 300 is used to block the port on one side of the main body 100. The inner pin 300 squeezes the side of the main body 100 away from the outer shell of the box body to seal the through hole port in the middle of the main body 100, so that external dust, moisture or water vapor cannot enter the outer shell of the box body from the port position of the main body 100, thereby achieving a good waterproof and dustproof effect; the inner pin 300 is fixedly arranged on the cap 2 00 is on the side facing the main body 100, and the connecting component is arranged in the cap 200. The cap 200 is detachably connected to the main body 100 through the connecting component. The inner pin 300 and the cap 200 can be integrally injection molded, glued and fixed, or detachably fixed, so that the cap 200 can be detached from one side of the main body 100 and the inner pin 300 can be separated therefrom at the same time, so that the port position of the main body 100 can be exposed to meet the discharge treatment of condensed water in the box shell, and the cap 200 forms a detachable connection with the main body 100 through the connecting component, so that when the cap 200 is connected to the main body 100 through the connecting component, the cap 200 can provide an extrusion force on the inner pin 300 toward the main body 100, so that the pressure effect required by the inner pin 300 to seal the port of the main body 100 can be met, thereby ensuring the sealing of the port position of the main body 100, and at the same time making the unlocking operation of the port seal of the main body 100 more convenient and efficient, so as to meet the needs of convenient use and repeated use.

[0030] The connecting assembly includes a fixed claw 400, a reset spring 500 and a button 600. The fixed claw 400 is integrally formed with a plurality of claws extending toward the main body 100. The reset spring 500 is arranged between the inner pin 300 and the fixed claw 400. The reset spring 500 is used to provide an elastic thrust for the automatic reset of the fixed claw 400. The button 600 is in a convex shape. The button 600 is arranged on the side of the fixed claw 400 away from the main body 100. A telescopic through hole is provided on the end face of the cap 200 for the end of the button 600 to extend out. A sealing gasket 301 is fixedly connected to the side of the inner pin 300 close to the main body 100. The diameter of the sealing gasket 301 is smaller than the diameter of the annular groove. A plurality of through-claw openings are spaced apart on the outer wall of the inner pin 300 close to the end of the fixed claw 400. The outer wall of the claw groove 302 is in the shape of an arc slope, and the multiple claws on the fixed claw 400 gradually move closer in the direction away from the fixed claw 400, and the side of the inner pin 300 close to the fixed claw 400 is provided with an elastic positioning groove 303 that is recessed inwardly; the side of the main body 100 close to the inner pin 300 is provided with an annular groove, and the end of the annular groove away from the inner pin 300 is in a convex shape that is recessed toward the center of the main body 100; in this connecting assembly, in the initial state, the end of the claw extending outward on the fixed claw 400 hooks the convex part of the inner side of the annular groove on the main body 100, and the reset spring 500 is in the initial compression state. The elastic thrust provided by the reset spring 500 makes the claw part of the fixed claw 400 and the annular opening of the main body 100 collide. A gripping force is formed between the inner walls of the groove, so that the cover cap 200 and the main body 100 are in a fixed state, and the fixing claw 400 can also provide an extrusion effect on the inner pin 300 by using the return spring 500, so that the inner pin 300 and the port of the main body 100 are kept in a tightly extruded state, thereby ensuring the sealing of the port of the main body 100; similarly, when removing the inner pin 300, it is only necessary to manually press the button 600 inward at the end surface of the cover cap 200, so that the button 600 drives the fixing claw 400 to move toward the direction close to the main body 100, and further squeeze the return spring 500. Since the inner pin 300 has a claw groove 302 on the side close to the fixing claw 400, the claw part of the fixing claw 400 can be expanded and guided, so that the fixing claw 400 is When moving further toward the main body 100, the claw portion on the fixing claw 400 can expand outward, so that the end position of the claw on the fixing claw 400 is separated from the inner wall of the annular groove on the main body 100, and the clamping state between the two is released. In this state, the cap 200 and the inner pin 300 can be removed from the side position of the main body 100, so that the port of the main body 100 is exposed to facilitate the discharge of condensed water. In addition, the end of the claw on the fixing claw 400 has a bevel, which can play a guiding role when it is inserted into the annular groove on the side of the main body 100, so that the cap 200 can be automatically connected and locked when it is installed to the side wall of the main body 100, making the assembly of the cap 200 at the side wall position of the main body 100 more convenient and efficient.

[0031] In addition, an annular groove is provided on one side of the cap 200 close to the main body 100, and the cap 200 is fixedly connected to an O-ring 700 through the annular groove. The provision of the O-ring 700 can enhance the air tightness of the connection surface between the cap 200 and the main body 100, and at the same time can also provide buffer protection for the two when they are spliced ​​and aligned.
