Description

Technical Field

[0001] This utility model relates to the field of electrical component protection technology, and in particular to a moisture-proof, waterproof, and airtight safety protection device for electrical components. Background Technology

[0002] Currently, existing safety protection devices (such as patent publication number: CN218940371U) disclose a waterproof and moisture-proof electrical control device. It injects air into the cabinet through an axial flow fan, and with the help of multiple oblique holes, it accelerates the airflow inside the cabinet, which is conducive to heat dissipation and cooling of electrical components. At the same time, a sealing cover is installed, and an electric push rod is activated to drive the connecting plate to adjust the height of the baffle, so that the air vents and oblique holes are staggered, thereby increasing the airtightness of the cabinet and preventing water from entering the cabinet on rainy days, thus achieving the purpose of waterproofing.

[0003] In the aforementioned patent, the internal wiring harness needs to be connected to the outside (such as power cords and signal lines) through the outer shell holes. The sealing is increased by adding a rubber sleeve. However, the rubber sleeve is difficult to completely cover the gaps. The surface tension of water may cause water to seep in along the edge of the holes, affecting the use of electrical components. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a moisture-proof, waterproof, and airtight safety protection device for electrical components. It solves the technical problem that internal wiring harnesses need to be connected to the outside (such as power lines and signal lines) through holes in the outer casing. While adding a rubber sleeve to increase the seal can increase the seal, the rubber sleeve cannot completely cover the gaps, and the surface tension of water may cause water to seep in along the edge of the hole, affecting the use of electrical components.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A moisture-proof, waterproof, and airtight safety protection device for electrical components includes a cover plate and a sealed box; An installation ring is fixedly installed on the side end of the sealed box body. A spiral ring is fixedly installed on the outer side of the installation ring. A waterproof ring is fixedly installed on the inner side of the installation ring. A knob cylinder is rotatably installed on the surface of the spiral ring. A clamping ring is fixedly installed on the side end of the knob cylinder.

[0006] Preferably, two closing strips are fixedly installed at the end of the sealed box body, and each closing strip has an arc-shaped structure; An elastic sealing strip is fixedly installed at the top of the cover plate, and two rubber strips are fixedly installed at the top of the cover plate. The inner side of the elastic sealing strip has an arc-shaped structure.

[0007] Preferably, a pivot seat is fixedly installed at the top of the sealing box, and each pivot seat is connected to the cover plate via a shaft. Each of the adhesive strips is aligned with the groove at the end of the sealing box, and each of the adhesive strips is spaced apart from the elastic sealing strip.

[0008] Compared with the prior art, the present invention has the following beneficial effects; In this invention, the knob cylinder is rotated clockwise on the surface of the spiral ring, which moves and causes the clamping ring to be squeezed into the interior of the waterproof ring sleeve. The clamping ring has a raised structure, and the compression causes the waterproof ring sleeve to deform, filling the gap between the wire harness and the sealing box. Furthermore, since the helix angle of the spiral ring and the knob cylinder is less than the friction angle, the knob cylinder can lock itself after it stops rotating. The mechanical locking achieves physical isolation between the groove and the external environment, preventing moisture intrusion and ensuring sealing stability.

[0009] In this invention, the elastic sealing strip is made of flexible material. When the arc-shaped closing strip at the end of the sealing box is pressed, it is embedded inside the elastic sealing strip. The two rub against each other to form a sealing structure of "flexible wrapping + arc-shaped fitting". When the cover plate is closed, the elastic buckle plate rubs against the outside of the sealing box to lock it in place. This can firmly fix the cover plate and the sealing box to prevent the box from loosening due to vibration or external impact, and ensure that the sealing structure does not fail during long-term use.

[0013] This application provides a moisture-proof, waterproof, and airtight safety protection device for electrical components. It effectively solves the problem that internal wiring harnesses need to connect to the outside (such as power lines and signal lines) through openings in the outer casing. While adding a rubber sleeve to increase sealing can improve performance, the sleeve may not completely cover the gaps, allowing water to seep in along the edges of the openings due to surface tension, affecting the use of the electrical components. Twisting the knob cylinder allows it to move clockwise on the surface of the spiral ring, causing the clamping ring to be squeezed into the waterproof ring sleeve. The clamping ring has a raised structure, and the compression deforms the waterproof ring sleeve, filling the gap between the wiring harness and the sealed housing. Furthermore, because the helix angle of the spiral ring and the knob cylinder is less than the friction angle, the knob cylinder can lock itself after stopping rotation. This mechanical locking physically isolates the slot from the external environment, preventing moisture intrusion and ensuring sealing stability.

[0014] Example like Figure 1 - Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problem that internal wiring harnesses need to be connected to the outside (such as power lines and signal lines) through the outer shell holes. While adding a rubber sleeve to increase sealing is necessary, the sleeve cannot completely cover the gaps, and the surface tension of water may cause water to seep in along the edges of the holes, affecting the use of electrical components. The overall approach is as follows: To address the problems existing in the prior art, this utility model provides a moisture-proof, waterproof, and airtight safety protection device for electrical components, including a cover plate 11 and a sealing box 14. By rotating the cover plate 11 and the sealing box 14, the sealing box 14 is fastened to the top of the cover plate 11, and at the same time, the end of the sealing box 14 is connected to the elastic sealing strip 12 to increase the sealing performance. A mounting ring 17 is fixedly installed on the side end of the sealed box 14. A spiral ring 21 is fixedly installed on the outer side of the mounting ring 17, and a waterproof ring sleeve 19 is fixedly installed on the inner side of the mounting ring 17. A knob cylinder 18 is rotatably mounted on the surface of the spiral ring 21, and a clamping ring 22 is fixedly installed on the side end of the knob cylinder 18. By passing the wire harness through the inside of the mounting ring 17 and turning the knob cylinder 18, the knob cylinder 18 rotates clockwise on the surface of the spiral ring 21. The rotation and movement of the knob cylinder 18 adjusts the clamping ring 22 to squeeze into the waterproof ring sleeve. Inside the waterproof ring 19, the clamping ring 22 has a raised structure. The clamping ring 22 slides into the interior of the waterproof ring 19, squeezing the inner side of the waterproof ring 19 and causing the waterproof ring 19 to deform, filling the gap between the wire harness and the sealing box 14. Through mechanical locking, the slot is physically isolated from the external environment to prevent moisture intrusion. At the same time, the thread helix angle of the spiral ring 21 and the knob cylinder 18 is smaller than the friction angle. When the knob cylinder 18 stops rotating, the spiral ring 21 and the knob cylinder 18 can lock themselves, increasing stability. Two closing strips 16 are fixedly installed at the end of the sealing box 14. Each closing strip 16 has an arc-shaped structure. By aligning the end of the sealing box 14 with the cover plate 11 and pressing the top of the sealing box 14, the end of the sealing box 14 moves the closing strip 16 into the interior of the elastic sealing strip 12. The closing strip 16 rubs against the inner side of the elastic sealing strip 12, and the cover plate 11 and the sealing box 14 are assembled and installed. An elastic sealing strip 12 is fixedly installed on the top of the cover plate 11, and two rubber strips 13 are fixedly installed on the top of the cover plate 11. The inner side of the elastic sealing strip 12 has an arc-shaped structure. The elastic sealing strip 12 and the rubber strip 13 are connected to the sealing box 14. The elastic sealing strip 12 is made of flexible material. The elastic sealing strip 12 rubs against the closing strip 16, causing the knob cylinder 18 to deform and fit against the closing strip 16. At the same time, the rubber strip 13 is connected to the sealing box 14, allowing the rubber strip 13 to be squeezed into the groove at the end of the sealing box 14. Through multiple methods, the sealing performance of the cover plate 11 and the sealing box 14 is increased. A pivot seat 15 is fixedly installed at the top of the sealed box 14. The pivot seat 15 is connected to the cover plate 11 through a shaft. The pivot seat 15 at the top of the sealed box 14 connects the cover plate 11 and the sealed box 14. The cover plate 11 can rotate around the pivot seat 15 to realize the opening or closing operation. An elastic buckle is installed at the other end of the cover plate 11. When the cover plate 11 is closed, the cover plate 11 is connected to the top of the sealed box 14. The cover plate 11 drives the elastic buckle on one side to rub against the outside of the sealed box 14 to realize the sealed connection between the cover plate 11 and the sealed box 14. Each rubber strip 13 is aligned with the groove at the end of the sealing box 14. Each rubber strip 13 is spaced from the elastic sealing strip 12. After the sealing box 14 and the cover plate 11 are aligned, the elastic sealing strip 12 and the closing strip 16 are aligned and rubbed together, and the two closing strips 16 are rubbed and squeezed into the inner side of the elastic sealing strip 12, thereby increasing the sealing performance of the cover plate 11 and the sealing box 14.

[0015] Working principle: The first step, the work begins, involves rotating the cover plate 11 to press and squeeze the sealing box 14, thus securing the sealing box 14 to the top of the cover plate 11. This establishes the basic structure for subsequent moisture-proof and waterproof operations. The elastic sealing strip 12 fixed to the top of the cover plate 11 is made of flexible material. The sealing box 14 has two arc-shaped closing strips 16 at its end. During the connection, the end of the sealing box 14 is aligned with the cover plate 11. Pressing the top of the sealing box 14 causes its end to pull the closing strip 16 into the interior of the elastic sealing strip 12. The two rub against each other, initially enhancing the seal between the cover plate 11 and the sealing box 14. Two rubber strips 13 are also fixed to the top of the cover plate 11. Each rubber strip 13 connects with the groove at the end of the sealing box 14, leaving a gap between it and the elastic sealing strip 12. After connection, the rubber strip 13 is squeezed into the groove at the end of the sealing box 14, further enhancing the seal.

[0016] The second step involves fixing a mounting ring 17 to the side end of the sealing box 14. A spiral ring 21 is provided on the outer side of the ring 17, and a waterproof ring sleeve 19 is provided on the inner side. A knob cylinder 18 is rotatably mounted on the surface of the spiral ring 21. A clamping ring 22 is provided on the side end of the knob cylinder 18. When the wire harness is inserted, it first passes through the inside of the mounting ring 17 (one end connects to an electrical component). Twisting the knob cylinder 18 causes it to rotate clockwise on the surface of the spiral ring 21, which in turn pushes the clamping ring 22 into the interior of the waterproof ring sleeve 19. The clamping ring 22 has a raised structure, and the compression deforms the waterproof ring sleeve 19, filling the gap between the wire harness and the sealing box 14. Furthermore, because the helix angle of the spiral ring 21 and the knob cylinder 18 is less than the friction angle, the knob cylinder 18 can lock itself after it stops rotating. This mechanical locking physically isolates the slot from the external environment, preventing moisture intrusion and ensuring sealing stability.

[0017] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
