[0026] When the existing high-density electrical method instrument is working in a humid environment and is connected to an external cable, it is easy for the cable surface to be contaminated with liquids such as water droplets, so that when the cable is connected to the high-density electrical method instrument, it is easy to carry liquid into the interior of the instrument, and cause immeasurable damage to the precision instruments inside the high-density electrical method instrument, reducing the working efficiency of the high-density electrical method instrument and making it inconvenient to use. Therefore, after research, the inventor provides a high-density electrical method instrument that prevents water from entering the cable connection. Through the coordinated use of a sealing component and a wiping component, the connection between the cable and the electrical method instrument body is sealed, and the situation in which liquid is carried into the high-density electrical method instrument by the cable is avoided, and the protection of the high-density electrical method instrument is improved. After long-term use, the sealing component can be cleaned of the contaminated liquid by the wiping component, thereby preventing the sealing component from rusting or being damaged after long-term use, improving the service life of the sealing component, and being easy to use, thereby solving the above-mentioned defects.

[0027] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] Please refer to Figures 1 to 8 The embodiment of the utility model provides a high-density electrical instrument for preventing water from entering the cable connection, including an electrical instrument body 1, an installation box 2 is installed on the left side of the electrical instrument body 1, and a sealing component 3 is provided in the inner cavity of the installation box 2. The sealing component 3 includes a mounting seat 31 and a rotating rod 33. The inner side of the mounting seat 31 is rotatably connected to the rotating rod 33. A connection box 32 is connected to the left side of the installation box 2, and the bottom of the mounting seat 31 is connected to the installation box 2. The left end of the rotating rod 33 penetrates into the inner cavity of the connection box 32, and the left end of the rotating rod 33 is rotatably connected to the connection box 32. A push block 34 is connected to the surface of the rotating rod 33, and a worm gear 35 is connected to the surface of the rotating rod 33. The front side of the inner cavity of the installation box 2 is rotatably connected to A worm 36, and the rear end of the worm 36 penetrates to the outside of the installation box 2, the rear end of the worm 36 is connected to a handle for easy rotation, the worm 36 is meshed with the worm wheel 35, the front and rear sides of the inner cavity of the installation box 2 are slidably connected with a moving rod 37, the front and rear sides of the inner cavity of the installation box 2 are connected with a return spring 310, the end of the return spring 310 away from the installation box 2 is connected to the moving rod 37, wherein the top and bottom of the installation box 2 are provided with a through cavity adapted to the moving rod 37, the top and bottom of the moving rod 37 are extended to the outside of the installation box 2 and are connected with a guide rod 38, the end of the guide rod 38 away from the moving rod 37 is connected with a sealing component 39, and the sealing component 39 seals flanges and other sealing parts;

[0029] Specifically, the user can twist the handle, and the handle drives the worm 36 to mesh and rotate with the worm wheel 35, so that the worm wheel 35 drives the rotating rod 33 to rotate. The rotating rod 33 drives the wiping assembly 4 and the push block 34 to move while rotating. The push block 34 rotates to a vertical state, so that the two moving rods 37 have no resistance, so that the moving rods 37 move in opposite directions relying on the elastic force of the return spring 310. The moving rod 37 drives the guide rod 38 and the sealing component 39 to move synchronously, so as to clamp and seal the cable, thereby preventing the cable from carrying water into the electrical instrument body 1 in a humid environment, and facilitating the sealing treatment of the connection between the cable and the electrical instrument body 1;

[0030] Please refer to Figures 2 to 8The surface of the connection box 32 is provided with a wiping assembly 4, and the wiping assembly 4 includes a first bevel gear 41 connected to the surface of the rotating rod 33. The front side of the connection box 32 is penetrated by a second bevel gear 42, wherein the second bevel gear 42 and the connection box 32 are rotatably connected in an area where they penetrate and contact each other through a bearing, the first bevel gear 41 is meshed with the second bevel gear 42, the front end of the second bevel gear 42 is connected to a gear 43, and the surface of the connection box 32 is slidably connected to a toothed plate 44, and as shown in Figure 4 As shown, a through cavity matched with the tooth plate 44 is opened on the left side of the installation box 2, and the user can reduce or increase the teeth of the tooth plate 44 according to the actual operation conditions. A positioning frame 45 is slidably connected to the surface of the connection box 32, and the tooth plate 44 is meshed with the gear 43. The top and bottom of the right side of the positioning frame 45 are connected with elastic components 46, wherein the elastic component 46 is composed of an elastic component and a sponge, wherein the sponge is installed on the outer surface of the elastic component, and the elastic component 46 is inclined, and the inclination angle can be changed according to the actual operation scene;

[0031] Specifically, when it is necessary to wipe the sealing component 39, the rotating rod 33 can be used to drive the first bevel gear 41 and the second bevel gear 42 to engage and rotate, and the rotating rod 33 drives the two sealing components 39 to move in opposite directions due to its rotation in the opposite direction, and the second bevel gear 42 drives the gear 43 to rotate, and while the gear 43 rotates, it engages with the toothed plate 44 for transmission, so that the toothed plate 44 moves to the position of the installation box 2. At this time, it should be noted that the push block 34 is in a horizontal and vertical state during the movement of the toothed plate 44, and because the toothed plate 44 is higher than the push block 34, the toothed plate 44 is prevented from hitting the push block 34. In the event of a collision during movement, the toothed plate 44 drives the positioning frame 45 and the elastic component 46 to move synchronously. When the sealing component 39 is expanded outward, the elastic component 46 moves toward it. When the elastic component 46 contacts the sealing component 39, the elastic component 46 is compressed due to the limitation of its material. When the sealing component 39 is expanded outward to a certain extent and the sealing component 39 and the elastic component 46 are in a non-contact state, the elastic component 46 is reset without external force and wipes the surface of the sealing component 39 when it is reset and expanded, so as to facilitate the cleaning of the sealing component 39.

[0032] In summary, the working principle of a high-density electrical instrument that prevents water from entering the cable connection is as follows: when the user can seal and protect the electrical instrument body 1 and the cable connection through the sealing component 3, the cable is prevented from carrying external liquid into the electrical instrument body 1, and the sealing component 39 is prevented from contacting the liquid on the cable surface, so that liquid gradually accumulates in the inner cavity of the sealing component 39, and then causes the liquid to rust the sealing component 39, ultimately avoiding a reduction in its service life. At this time, while utilizing the sealed movement state between the contact sealing component 3 and the cable, the sealing component 3 can be driven by the wiping component 4 to wipe the liquid on the sealing component 39, thereby preventing the liquid from damaging the sealing component 39, and facilitating use due to its reduced protectiveness.

For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
