Detailed implementation manners

[0018] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0019] The first embodiment of the present application is as follows:

[0020] Please refer to Figures 1-3 , in which Figure 1 is the overall structural schematic diagram of the first embodiment of the present utility model; Figure 2 is the structural schematic diagram inside the storage box of the first embodiment of the present utility model; Figure 3 is Figure 2 The sectional view taken along line A-A in

[0021] The present utility model provides a grounding device for electrical tests, which includes a box body 101, a movable plate 102 and a grounding component. The grounding component includes a storage box 103, a plurality of fixed rods 104, a driving plate 105, a support frame 114, a driving component and a plurality of rotation connection components. The driving component includes a driving motor 106, a driving stud 107 and four auxiliary rods 108. The rotation connection components include a threaded sleeve 109, a rotating stud 110 and a connecting member. The connecting member includes a rotating frame 111, a rotating column 112 and a limit turntable 113. Through the foregoing solution, the problem that in the existing grounding device for electrical tests, after the support rod is inserted into the ground, the entire device needs to be lifted to be pulled out, and during continuous use, the operation is inconvenient and the test preparation time will be longer is solved.

[0022] For this specific embodiment, the movable plate 102 is slidably disposed below the box body 101, the storage box 103 is fixedly connected above the movable plate 102, a plurality of the fixed rods 104 are slidably disposed below the movable plate 102, the driving plate 105 is slidably connected within the storage box 103, the support frame 114 is fixedly connected below the movable plate 102, the driving assembly is located between the movable plate 102 and the driving plate 105, and each of the rotation connection assemblies is located between each of the fixed rods 104 and the driving plate 105. When inserting the fixed rods 104, the driving assembly is started to press down the driving plate 105, so that the plurality of rotation connection assemblies respectively drive the plurality of fixed rods 104 to descend and rotate. The rotating fixed rods 104 can be inserted into the ground more easily. When removing the plurality of fixed rods 104, the driving assembly is started in the reverse direction, the driving plate 105 rises, so that the plurality of rotation connection assemblies respectively drive the plurality of fixed rods 104 to rise and rotate. The rotating fixed rods 104 can be withdrawn from the ground more easily, and the operation is convenient and labor-saving.

[0023] Among them, the driving motor 106 is fixedly connected above the movable plate 102, the driving screw rod 107 is fixedly connected to the output end of the driving motor 106 and is threadedly connected to the driving plate 105. Four auxiliary rods 108 are fixedly connected within the storage box 103 and penetrate through the driving plate 105. When driving the plurality of fixed rods 104 to move up and down, the driving motor 106 is started, the driving screw rod 107 rotates, so that the driving plate 105 moves up and down stably with the assistance of the four auxiliary rods 108, thereby driving the plurality of fixed rods 104 to move up and down through the plurality of rotation connection assemblies, so as to insert into or withdraw from the ground.

[0024] Secondly, the threaded sleeve 109 is fixedly connected within the movable plate 102, the rotating screw rod 110 is fixedly connected above the fixed rod 104 and is threadedly connected to the threaded sleeve 109. The connecting member is located between the rotating screw rod 110 and the driving plate 105. When the driving plate 105 moves up and down, the rotating screw rod 110 is driven to move up and down through the connecting member, so that the fixed rod 104 moves up and down accordingly, inserting into or withdrawing from the ground. At the same time, under the action of the connecting member and the threaded sleeve 109, the rotating screw rod 110 drives the fixed rod 104 to rotate while moving up and down, reducing the resistance of the fixed rod 104 when inserting into or withdrawing from the ground.

[0025] Meanwhile, the rotating frame 111 is fixedly connected to the lower part of the driving plate 105, the rotating column 112 is fixedly connected to the upper part of the rotating screw 110, the limiting turntable 113 is fixedly connected to the rotating column 112 and is rotatably connected to the inside of the rotating frame 111. When the driving plate 105 moves up and down, the rotating frame 111 and the rotating column 112 drive the rotating screw 110 to move up and down. Since the rotating column 112 and the limiting turntable 113 are rotatably connected to the rotating frame 111, under the action of the threaded sleeve 109, the rotating screw 110 drives the fixed rod 104 to rotate while moving up and down, so as to be more conveniently and labor-savingly inserted into or pulled out of the ground.

[0026] When inserting the fixed rod 104, the device is stabilized at the target position through the support frame 114, the driving motor 106 is started, the driving screw 107 rotates, so that the driving plate 105 is stably pressed down with the assistance of the four auxiliary rods 108, and the plurality of rotating connection components respectively drive the plurality of fixed rods 104 to descend. When the rotating connection components are pressed down, the rotating frame 111 and the rotating column 112 drive the rotating screw 110 to descend. Since the rotating column 112 and the limiting turntable 113 are rotatably connected to the rotating frame 111, under the action of the threaded sleeve 109, the rotating screw 110 rotates, driving the rotating column 112, the limiting turntable 113 and the fixed rod 104 to rotate while descending, so as to be more conveniently and labor-savingly inserted into or pulled out of the ground. At the same time, while allowing the rotating screw 110 and the rotating column 112 to rotate, the limiting turntable 113 restricts them to always be located below the driving plate 105, and no skewing will occur; when taking out the plurality of fixed rods 104, the driving component is started in the reverse direction. By the same principle as above, the plurality of fixed rods 104 rise stably and rotate, and the rotating fixed rods 104 can be more easily pulled out of the ground. The operation is convenient and labor-saving, avoiding the problem that in the prior art, after the support rod is inserted into the ground, the whole device needs to be lifted to be pulled out, and during continuous use, the operation is inconvenient and the test preparation time will be longer. The effect of convenient operation and shortened test preparation time is obtained.

[0027] The second embodiment of the present application is as follows:

[0028] Please refer to Figure 4 , Figure 4 which is the overall structural schematic diagram of the second embodiment of the present utility model.

[0029] On the basis of the first embodiment, the electrical test grounding device of this embodiment further includes a moving mechanism, and the moving mechanism includes four universal wheels 201 and a push handle 202.

[0030] Among them, the four universal wheels 201 are rotatably connected to the lower part of the support frame 114, and the push handle 202 is fixedly connected to one side of the movable plate 102. When moving the device, hold the push handle 202 to push the device. With the assistance of the four universal wheels 201, the storage box 103 and components such as the box body 101 are driven by the support frame 114 to move, achieving the effect of conveniently moving the device.

[0031] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
