However, the suction cups always protrude from the lower surface, making them prone to sticking to the surface and inconvenient to handle. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a power quality analyzer with drop protection, solving the problems mentioned in the background section. To achieve the above objectives, this utility model is implemented through the following technical solution: a power quality analyzer with drop protection, comprising a power quality analyzer body, a base hinged to the bottom of the power quality analyzer body, a suction cup fixedly connected to the bottom of the base, a support assembly on the outer surface of the power quality analyzer body, a protective assembly below the base, the protective assembly including a baffle, an airbag at the bottom of the baffle, an air chamber connected by a pipeline above the airbag, a piston rod slidably connected to the inner surface of the air chamber, and a shielding assembly above the power quality analyzer body.

[0005] Preferably, the support assembly includes a limiting sleeve, which is rotatably connected to the front of the power quality analyzer body and fixedly connected to the bottom of the air chamber, with a bolt threaded through the front of the limiting sleeve.

[0006] Preferably, the bracket assembly further includes a sliding rod, which is slidably connected to the inner surface of the limiting sleeve, rotatably connected to the front of the power quality analyzer body, and fixedly connected to the lower end of the piston rod.

[0007] Preferably, the shielding component includes a support plate, which is fixedly connected to the left side of the power quality analyzer body. A rotating column is rotatably connected through the top of the support plate. There are two rotating columns. A stop bar is fixedly connected to the outer surface of each of the two rotating columns. A first gear is fixedly connected to the outer surface of each of the two rotating columns. The two first gears mesh with each other. A driving component is provided on the front of the shielding component.

[0008] Preferably, the driving component includes a rotating rod, a shaft bracket is rotatably connected to the outer surface of the rotating rod, the shaft bracket is fixedly connected to the left side of the power quality analyzer body, a first bevel gear is fixedly connected to the rear end of the rotating rod, a second bevel gear meshes with the back of the first bevel gear, and the second bevel gear is fixedly connected to the lower end of the rotating column.

[0009] Preferably, the driving assembly further includes a second gear, which is fixedly connected to the front end of the rotating rod. A toothed ring is engaged at the bottom of the second gear, and the toothed ring is fixedly connected to the front of the baffle.

[0010] The advantages of this application are:

[0011] (1) This application uses a suction cup to attach to a flat surface to prevent accidental contact that could cause the power quality analyzer body to fall. The protective component protrudes from the suction cup under normal conditions. When the power quality analyzer body is propped up, it will drive the bracket assembly to depress the protective component so that it no longer protrudes from the suction cup, thus preventing the suction cup from sticking to the flat surface when the power quality analyzer body is placed normally.

[0012] (2) This application uses a shielding component to shield and protect the upper surface of the power quality analyzer body. When the power quality analyzer body is raised, the driving component will also move the shielding component away from the upper surface of the power quality analyzer body, thus providing protection for the power quality analyzer body when it is in the retracted state.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example 1

[0021] See Figures 1-4This embodiment provides a power quality analyzer with drop protection, including a power quality analyzer body 1. A base 2, L-shaped, is hinged to the bottom of the power quality analyzer body 1. The hinge point between the power quality analyzer body 1 and the base 2 is located on the left side. Two suction cups 3 are fixedly connected to the bottom of the base 2. Two sets of support assemblies 4 are symmetrically arranged on the front and rear sides of the power quality analyzer body 1, with each support assembly 4 including a limiting sleeve 401, which is square-shaped. The limiting sleeve 401 is rotatably connected to the front of the power quality analyzer body 1 and fixedly connected to the bottom of the air chamber 503. A bolt 402 is threaded through the front of the limiting sleeve 401. The support assembly 4 also includes a sliding rod 403, which is square in shape. The sliding rod 403 is slidably connected to the inner surface of the limiting sleeve 401. The sliding rod 403 is rotatably connected to the front of the power quality analyzer body 1. The sliding rod 403 is fixedly connected to the lower end of the piston rod 504. A protective assembly 5 is provided below the base 2. The protective assembly 5 includes a baffle 501. An opening is provided below the baffle 501 to accommodate the suction cup 3. An airbag 502 is provided at the bottom of the baffle 501. An air chamber 503 is connected to the airbag 502 by a pipeline. The air chamber 503 and the airbag 502 are connected and communicated by a hose. A piston rod 504 is slidably connected to the inner surface of the air chamber 503. There are two airbags 502, air chambers 503 and piston rods 504. A shielding assembly 6 is provided above the power quality analyzer body 1.

[0022] In practical use, the above-mentioned equipment uses baffles 501 to protect both sides of the power quality analyzer body 1. When the power quality analyzer body 1 needs to be erected on a flat surface, it is tilted upward on the base 2 to make it stand up. At this time, the power quality analyzer body 1 will pull the limiting sleeve 401 to slide on the outer surface of the sliding rod 403. By rotating the bolt 402 on the limiting sleeve 401, friction is applied to the sliding rod 403 to facilitate fixation. At this time, the sliding of the limiting sleeve 401 on the outer surface of the sliding rod 403 will also drive the piston rod 504 to slide in the air chamber 503. The piston rod 504 will draw gas from the air bag 502 through the hose, causing the air bag 502 to deflate. At this time, the suction cup 3 can contact the flat surface to be fixed on the flat surface. Example 2

[0023] See Figures 1-4Based on Embodiment 1, the shielding component 6 includes a support plate 601, which is fixedly connected to the left side of the power quality analyzer body 1. A rotating column 602 is rotatably connected through the top of the support plate 601. A bearing is provided between the rotating column 602 and the support plate 601. There are two rotating columns 602. A baffle 603 is fixedly connected to the outer surface of each of the two rotating columns 602. A columnar rubber pad is provided on the outer surface of the baffle 603. A first gear 604 is fixedly connected to the outer surface of each of the two rotating columns 602. The two first gears 604 mesh with each other. A driving component 7 is provided on the front of the shielding component 6. The driving component 7 includes a rotating rod 701. The outer surface of the rotating rod 701 rotates... A shaft support 702 is dynamically connected, and a bearing is provided between the shaft support 702 and the rotating rod 701. The shaft support 702 is fixedly connected to the left side of the power quality analyzer body 1. A first bevel gear 703 is fixedly connected to the rear end of the rotating rod 701. A second bevel gear 704 meshes with the back of the first bevel gear 703. The second bevel gear 704 is fixedly connected to the lower end of the rotating column 602. The drive assembly 7 also includes a second gear 705. The second gear 705 is fixedly connected to the front end of the rotating rod 701. A gear ring 706 meshes with the bottom of the second gear 705. The center of the gear ring 706 is concentrically set with the hinge axis between the power quality analyzer body 1 and the base 2. The gear ring 706 is fixedly connected to the front of the baffle 501.

[0024] In actual use, the baffle 603 protects the top of the power quality analyzer body 1. When the power quality analyzer body 1 flips upward on the base 2, it also drives the shaft support 702 and the rotating rod 701 to make the second gear 705 roll on the gear ring 706. At this time, the second gear 705 drives the rotating rod 701 to rotate inside the shaft support 702. The rotation of the rotating rod 701 drives the first bevel gear 703 to rotate. The first bevel gear 703 drives the second bevel gear 704 to rotate the rotating column 602. The rotating column 602 drives the first gear 604 to rotate the other rotating column 602 in the opposite direction. At this time, the rotation of the two rotating columns 602 will cause the baffle 603 to open from the power quality analyzer body 1 to facilitate the use of the power quality analyzer body 1.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
