Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical switch technology, specifically a waterproof electrical switch for electrical engineering. Background Technology
[0002] An electrical switch is an electrical device used to control the on / off state of a circuit. A waterproof electrical switch is a specially designed switch that effectively prevents moisture from entering and affecting its normal function. In industrial production environments where there is water splashing, water mist, or humid air, such as food processing plants, electroplating workshops, and sewage treatment plants, waterproof electrical switches can prevent moisture damage to the switch, improve equipment reliability and service life, and reduce production interruptions caused by switch failures.
[0003] In some existing electrical engineering switches, the connection between the protective cover and the switch body often uses a fixed sealing design. This leads to a decrease in the fit between the sealing component and the protective cover during opening or closing, making it prone to momentary gaps. Liquids may then seep in, posing a potential hazard to the safe operation of the electrical switch. Therefore, we propose a waterproof electrical switch for electrical engineering. Utility Model Content
[0004] The purpose of this utility model is to provide a waterproof electrical switch for electrical engineering, in order to solve the problem mentioned in the background art that some existing electrical engineering switches use a fixed sealing design at the connection between the protective cover and the switch body. This causes the sealing component to lose its fit with the protective cover during the opening or closing process, making it easy for momentary gaps to appear. Liquid may then seep in, posing a potential hazard to the safe operation of the electrical switch.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof electrical switch for electrical engineering, comprising: a mounting body, a fixing plate fixedly connected to the outer surface of the mounting body, a protective box fixedly connected to the outer surface of the fixing plate, an opening and closing connecting shaft fixedly connected to the top of the protective box on the side away from the fixing plate, a protective cover movably connected to the outer surface of the opening and closing connecting shaft, a top protection component fixedly connected to the upper surface of the protective box, the protective cover and the protective box opening and closing via the opening and closing connecting shaft, the protective cover pushing and squeezing the top protection component when opening and closing upwards, and the top protection component tightly fitting against the contact point with the protective cover when displaced by force.
[0006] The top cover assembly includes an upper cover plate, which is movably connected to the top inward side of the protective cover. The upper cover plate is L-shaped, and a connecting plate is fixedly connected to the bottom of the upper cover plate. The upper cover plate and the connecting plate are movably connected above the connection between the protective cover and the protective box.
[0007] The connecting plate has a connecting rod fixedly connected to the end away from the upper cover plate, a limit plate fixedly connected to the outer surface of the connecting rod, and a spring column fixedly connected to the end of the limit plate away from the connecting rod.
[0008] The end of the spring column away from the limiting plate is fixedly connected to a fixed seat, and the spring column and the limiting plate are movably connected inside the fixed seat.
[0009] Among them, the connecting rods are symmetrically fixedly connected in two groups on the side of the connecting plate away from the upper cover plate, and the spring columns are fixedly connected in three groups between the limiting plate and the fixed seat.
[0010] Among them, the outer surface of the upper cover plate facing the protective cover is fixedly connected with an elastic rubber lip. The elastic rubber lip is fixedly connected in three groups to the two sides and the bottom of the protective box. The outer surface of the elastic rubber lip is movably connected with a protective groove. The protective groove is opened in three groups on the inner side of the protective cover facing the protective box.
[0011] This utility model has at least the following beneficial effects:
[0012] 1. In use, this utility model connects the protective cover with the opening and closing connecting shaft and the protective box. When opening and closing, the upper cover plate of the top protection component is pushed, causing the connecting plate and connecting rod to drive the limiting plate to compress the spring column in the fixing seat, thereby realizing the adaptive displacement of the top protection component. The elastic rubber lips on both sides and bottom of the upper cover plate and the protective box are nested and fitted with the protective groove on the inner side of the protective cover, forming multiple sealing barriers in both the opening and closing process and the closed state. This improves the problem of sealing failure when traditional switches are opened and closed, and significantly enhances waterproof reliability.
[0013] 2. In use, the mounting body securely fixes the protective box with a fixing plate. The two sets of symmetrical connecting rods and three sets of spring columns in the top protection component form a stable elastic support, ensuring smooth displacement of the upper cover plate. The protective cover rotates flexibly around the opening and closing connecting shaft. When opening, it does not affect the switch operation. When closing, the spring columns automatically push each component to reset, keeping the elastic rubber lip tightly fitted. This improves the problems of cumbersome operation and insufficient stability of traditional waterproof structures, taking into account both protective performance and ease of use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This utility model provides a technical solution: a waterproof electrical switch for electrical engineering, comprising: a mounting body 1, a fixing plate 2 fixedly connected to the outer surface of the mounting body 1, a protective box 3 fixedly connected to the outer surface of the fixing plate 2, an opening and closing connecting shaft 8 fixedly connected to the top of the protective box 3 on the side away from the fixing plate 2, a protective cover 4 movably connected to the outer surface of the opening and closing connecting shaft 8, and a top protection component 5 fixedly connected to the upper surface of the protective box 3. The protective cover 4 and the protective box 3 are opened and closed through the opening and closing connecting shaft 8. When the protective cover 4 opens and closes upward, it pushes and squeezes the top protection component 5. When the top protection component 5 is displaced by force, it will tightly fit against the contact point with the protective cover 4.
[0021] In use, the protective cover 4 is connected to the opening and closing connecting shaft 8 and the protective box 3. When opening and closing, the upper cover plate 51 of the top protection component 5 is pushed, so that the connecting plate 52 and the connecting rod 53 drive the limiting plate 54 to compress the spring column 55 in the fixing seat 56, thereby realizing the adaptive displacement of the top protection component 5. The elastic rubber lips 6 on both sides and bottom of the upper cover plate 51 and the protective box 3 are nested and fitted with the protective groove 7 on the inner side of the protective cover 4, forming multiple sealing barriers in the opening and closing process and in the closed state, which improves the problem of sealing failure when the traditional switch is opened and closed, and significantly improves the waterproof reliability.
[0022] The top cover assembly 5 includes an upper cover plate 51, which is movably connected to the top inward side of the protective cover 4. The upper cover plate 51 is L-shaped, and a connecting plate 52 is fixedly connected to the bottom of the upper cover plate 51. The upper cover plate 51 and the connecting plate 52 are movably connected above the connection between the protective cover 4 and the protective box 3.
[0023] A connecting rod 53 is fixedly connected to the end of the connecting plate 52 away from the upper cover plate 51. A limiting plate 54 is fixedly connected to the outer surface of the connecting rod 53. A spring post 55 is fixedly connected to the end of the limiting plate 54 away from the connecting rod 53. A fixing seat 56 is fixedly connected to the end of the spring post 55 away from the limiting plate 54. The spring post 55 and the limiting plate 54 are movably connected inside the fixing seat 56.
[0024] Two sets of connecting rods 53 are symmetrically fixedly connected to the side of the connecting plate 52 away from the upper cover plate 51. Three sets of spring columns 55 are fixedly connected between the limiting plate 54 and the fixing seat 56. An elastic rubber lip 6 is fixedly connected to the outer surface of the end of the upper cover plate 51 facing the protective cover 4. Three sets of elastic rubber lips 6 are fixedly connected to the sides and bottom of the protective box 3. A protective groove 7 is movably connected to the outer surface of the elastic rubber lip 6. Three sets of protective grooves 7 are opened on the inner side of the protective cover 4 facing the protective box 3.
[0025] In use, the mounting body 1 serves as the base of the device, and the protective box 3 is firmly fixed by the fixing plate 2 on the outer surface. The top of the protective box 3 on the side away from the fixing plate 2 is movably connected to the protective cover 4 by the opening and closing connecting shaft 8 as the pivot, so that the protective cover 4 can rotate flexibly around the opening and closing connecting shaft 8, thereby covering the opening of the protective box 3 and forming a physical barrier when it is opened and closed. When it is opened, it is convenient to operate the internal components of the switch.
[0026] When the protective cover 4 opens upwards, its top inward side contacts the upper cover plate 51 of the top protection assembly 5 and generates a thrust. In the top protection assembly 5, the L-shaped upper cover plate 51 covers the connection between the protective cover 4 and the protective box 3. The connecting plate 52 at its bottom connects to two sets of symmetrically distributed connecting rods 53. The end of the limiting plate 54 on the outer surface of the connecting rod 53 away from the connecting rod 53 is fixed to three sets of spring columns 55. The other end of the spring columns 55 is fixed inside the fixing seat 56, forming an elastic support structure. Under the thrust of the protective cover 4, the upper cover plate 51 drives the connecting rods 53 to move towards the fixing seat 56 through the connecting plate 52. The limiting plate 54 simultaneously compresses the spring columns 55, causing the top protection assembly 5 to undergo adaptive displacement as a whole, ensuring that the contact with the protective cover 4 remains tight.
[0027] When the protective cover 4 is closed, the spring column 55 releases its elastic potential energy, pushing the limiting plate 54, connecting rod 53, and connecting plate 52 to move in the opposite direction, causing the upper cover plate 51 to return to its original position. At this time, the elastic rubber lip 6 remains tightly fitted with the protective groove 7. Through the nested cooperation of the three sets of elastic rubber lips 6 and the protective groove 7, multiple sealing barriers are formed at the contact edge between the protective cover 4 and the protective box 3, completely blocking the path of liquid seepage from the gaps. This design, through the elastic linkage of the mechanical structure, ensures that the contact point between the top protective assembly 5 and the protective cover 4 is always sealed during the opening and closing process and in the closed state, significantly improving the waterproof reliability of the switch.
