DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1, reference Figure 1 to Figure 2 , which is the first embodiment of the present invention, provides a portable adjustable grounding device, comprising:

[0032] The rotating mechanism 100 includes an insulating rod 101 and a driving member arranged in the insulating rod 101. The top end of the insulating rod 101 is connected to a rotating rod 102 through the driving member. The outer wall of the rotating rod 102 is provided with a first umbrella-shaped gear 103. The outer wall of the rotating rod 102 is movably connected to a support frame 105. A second umbrella-shaped gear 104 is rotatably connected in the support frame 105. The second umbrella-shaped gear 104 is meshed with the first umbrella-shaped gear 103. In this embodiment, the driving member is a driving motor. The output shaft of the driving motor is connected to the rotating rod 102. The driving motor can drive the rotating rod 102 to rotate. The rotation of the rotating rod 102 causes the first umbrella-shaped gear 103 to rotate, and then causes the second umbrella-shaped gear 104 to rotate.

[0033] The grounding mechanism 200 includes a wire clamp 201 and a screw rod 202 threadedly connected to the wire clamp 201, and one end of the screw rod 202 is rotatably connected to an extrusion plate 203; in this embodiment, rotating the screw rod 202 can make the extrusion plate 203 close to the wire clamp 201 for clamping.

[0034] The second umbrella-shaped gear 104 is slidably connected to the screw rod 202 , and the driving member controls the rotation of the rotating rod 102 , and the rotation of the screw rod 202 is controlled by the transmission of the first umbrella-shaped gear 103 and the second umbrella-shaped gear 104 .

[0035] Specifically, a limiting protrusion 203a is provided on the extrusion plate 203, and a limiting groove matching the limiting protrusion 203a is provided on the inner wall of the wire clamp 201. The limiting protrusion 203a and the limiting groove are slidably connected. In this embodiment, the limiting protrusion 203a and the limiting groove cooperate with each other to improve the stability of the movement of the extrusion plate 203.

[0036] Furthermore, the first bevel gear 103 and the second bevel gear 104 are vertically arranged.

[0037] Example 2, reference Figure 1-2 , which is the second embodiment of the present invention, is different from the previous embodiment in that a washer 102a is provided on the rotating rod 102, and a thick shaft 102b is provided on the washer 102a.

[0038] Specifically, a thin shaft 102c is provided at one end of the thick shaft 102b, and the first bevel gear 103 is slidably disposed on the outer wall of the thin shaft 102c. In this embodiment, the diameter of the thick shaft 102b is larger than the thin shaft 102c, and the end of the first bevel gear 103 conflicts with the thick shaft 102b.

[0039] Furthermore, a stopper 102e is provided at the end of the thin shaft 102c.

[0040] A connecting shaft 202 a is provided at the end of the screw rod 202 , and the outer wall of the connecting shaft 202 a is slidably connected to the inner wall of the second bevel gear 104 .

[0041] The outer wall of the thin shaft 102c is provided with a first limit block 102d;

[0042] A second limiting block 202b is disposed on the outer wall of the connecting shaft 202a.

[0043] In this embodiment, the first limit block 102d can be set so that the thin shaft 102c rotates to drive the first bevel gear 103 to rotate, and the second limit block 202b can be set so that the connecting shaft 202a rotates to drive the second bevel gear 104 to rotate, thereby realizing transmission.

[0044] The rest of the structure is the same as that of Example 1.

[0045] Example 3, reference Figure 1-2 , which is the third embodiment of the present invention, and is different from the previous embodiment in that it further includes a limiting mechanism 300 and a positioning mechanism 400;

[0046] The limiting mechanism 300 includes a limiting frame 301 disposed on the outer wall of the insulating rod 101, and a clamping groove 301a disposed on the limiting frame 301;

[0047] The positioning mechanism 400 includes a fixing plate 401 disposed on the wire clamp 201 and a clamping block 402 disposed on the fixing plate 401;

[0048] The clamping groove 301a and the clamping block 402 are slidably connected.

[0049] Specifically, a sleeve 403 is provided in the clamping block 402, and a blocking ring 404 is provided at one end of the clamping block 402;

[0050] The connecting shaft 202 a passes through the sleeve 403 .

[0051] The rest of the structure is the same as that of Example 2.

[0052] When in use, the grounding wire is fixed to the wire clamp 201 by screws. The operator holds the insulating rod 101 and places the cable between the extrusion plate 203 and the wire clamp 201 when grounding is required. Figure 1 or Figure 2 Under the action of gravity, the support frame 105 is attached to the top of the gasket 102a, the bottom of the first umbrella gear 103 is attached to the top of the thick shaft 102b, the first umbrella gear 103 and the second umbrella gear 104 are in meshing state, the clamping block 402 is located in the clamping groove 301a, and the surface of the blocking ring 404 is attached to the limit frame 301;

[0053] The rotation of the rotating rod 102 is controlled by the driving member. Since the clamping groove 301a on the limit frame 301 clamps the clamping block 402, the rotation of the rotating rod 102 drives the first umbrella gear 103 to rotate, the first umbrella gear 103 drives the second umbrella gear 104 to rotate, and the second umbrella gear 104 drives the connecting shaft 202a to rotate, thereby causing the screw rod 202 to rotate, causing the extrusion plate 203 to slide, and the cable is clamped by the extrusion plate 203 and the wire clamp 201 to achieve a grounding operation.

[0054] After the grounding is completed, since the wire clamp 201 is clamped on the cable, the insulating rod 101 can be pulled down at this time, which will cause the rotating rod 102 to slide down relative to the support frame 105, and the thick shaft 102b and the thin shaft 102c to slide down, so that the first umbrella gear 103 and the second umbrella gear 104 lose engagement, and the snap-in groove 301a loses the snap-in connection with the snap-in block 402 after descending, and the limit frame 301 loses the obstruction of the blocking ring 404, so at this time, the connecting shaft 202a can be pulled out from the second umbrella gear 104, realizing the disengagement between the grounding mechanism 200, the positioning mechanism 400 and the rotating mechanism 100.

[0055] In summary, while facilitating automatic grounding, it can also achieve detachment of one grounding end, avoiding long-term weight on the cable after grounding, improving grounding safety, and reducing the weight of the cable at the grounding part. Since its end can be easily disassembled and separated, it can also be convenient for the operator to carry when in use.

[0056] Preferably, the clamping block 402 is square, so the opening direction of the clamp head 201 can be changed by adjusting the clamping angle of the clamping block 402 to achieve angle adjustment.

[0057] It should be noted that the opening direction of the clamp head 201 can be any direction, up, down, front, or back. Figure 1 The example shown is one in which the opening faces forward, and you can select another one according to your actual needs.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
