Description

Technical Field

[0001] The utility model relates to the technical field of live working at high voltage, in particular to a portable telescopic high-voltage operating rod. Background Art

[0002] When replacing the 10 kV high-voltage PT (fuse tube), high-voltage power outage operation is required. During the operation process, corresponding safety measures need to be taken, and there are many uncontrollable risk factors. Therefore, a high-voltage operating rod is usually used to assist in the operation. For the convenience of carrying, the existing drop-fuse operating rod is divided into three separate sections. Before use, each section needs to be manually connected, and the problem of disconnection of each section is likely to occur during the operation process. Moreover, since the upper metal operating head has a straight-head structure, the fuse tube is likely to be detached during the operation process. Content of the Utility Model

[0003] The purpose of the utility model is to provide a portable telescopic high-voltage operating rod aiming at the above deficiencies, which can effectively avoid the problem of disconnection of each section during the operation process and can also effectively avoid the situation of detachment of the fuse tube during the operation process.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A portable telescopic high-voltage operating rod includes an outer tube, a middle tube whose bottom end is slidably connected inside the outer tube, an inner tube whose bottom end is slidably connected inside the middle tube, an operating head detachably connected to the top end of the inner tube, an anti-disengagement structure arranged on the operating head, an internal thread one arranged at the top end of the outer tube, an external thread one arranged at the bottom end of the middle tube, an internal thread two arranged at the top end of the middle tube, an external thread two arranged at the bottom end of the inner tube, and the internal thread one and the external thread one are screwed tightly from bottom to top, and the internal thread two and the external thread two are screwed tightly from bottom to top.

[0006] Further, the anti-disengagement structure includes a straight connection part fixed to one end of the operating head, a V-shaped operating part connected to the end of the straight connection part away from the operating head, and the opening of the V-shaped operating part is arranged downward.

[0007] Further, a connection sleeve is fixed to the bottom end of the operating head, an external thread three is arranged at the top end of the inner tube, an internal thread three is arranged on the connection sleeve, and the internal thread three and the external thread three are screwed tightly.

[0008] Further, the outer diameter of the middle tube is greater than the outer diameter of the inner tube, and the outer diameter of the outer tube is greater than the outer diameter of the middle tube.

[0009] Further, a rubber insulating handle is sleeved on the outer tube.

[0010] The beneficial effects of the utility model are:

[0011] In practical applications, the outer tube, the middle tube, and the inner tube are connected by screwing the first internal thread and the first external thread tightly from bottom to top, and screwing the second internal thread and the second external thread tightly from bottom to top, effectively preventing the disconnection of each section during operation; by setting an anti-disengagement structure on the operating head, the disengagement of the fuse tube during operation can be effectively avoided; the utility model can not only effectively avoid the problem of disconnection of each section during operation, but also effectively avoid the disengagement of the fuse tube during operation.

[0015] As Figure 1 and Figure 2 shown, a portable telescopic high-voltage operating rod includes an outer tube 1, a middle tube 2 slidably connected to the bottom end inside the outer tube 1, an inner tube 3 slidably connected to the bottom end inside the middle tube 2, an operating head 4 detachably connected to the top end of the inner tube 3, an anti-disengagement structure provided on the operating head 4, a first internal thread provided at the top end of the outer tube 1, a first external thread provided at the bottom end of the middle tube 2, a second internal thread provided at the top end of the middle tube 2, a second external thread provided at the bottom end of the inner tube 3, and the first internal thread and the first external thread are screwed tightly from bottom to top, and the second internal thread and the second external thread are screwed tightly from bottom to top.

[0016] During use, the outer tube 1, the middle tube 2, and the inner tube 3 are connected by screwing the first internal thread and the first external thread tightly from bottom to top, and screwing the second internal thread and the second external thread tightly from bottom to top, effectively preventing the disconnection of each section during operation; by setting an anti-disengagement structure on the operating head 4, the disengagement of the fuse tube during operation can be effectively avoided; the utility model can not only effectively avoid the problem of disconnection of each section during operation, but also effectively avoid the disengagement of the fuse tube during operation.

[0017] As Figure 1 and Figure 2 shown, the anti-disengagement structure includes a straight connecting portion 51 fixed at one end to the operating head 4, a V-shaped operating portion 52 connected to the end of the straight connecting portion 51 away from the operating head 4, and the opening of the V-shaped operating portion 52 is arranged downward; in this embodiment, during the high-voltage power outage operation, the fuse tube can be more easily clamped by the V-shaped operating portion 52, avoiding the disengagement of the fuse tube during operation.

[0018] As Figure 1 and Figure 2 shown, a connecting sleeve 41 is fixed to the bottom end of the operating head 4. An external thread III is provided at the top end of the inner tube 3, and an internal thread III is provided on the connecting sleeve 41. The internal thread III is screwed tightly with the external thread III. In this embodiment, the operating head 4 is detachably connected to the inner tube 3 by screwing the internal thread III with the external thread III.

[0019] As Figure 1 and Figure 2 shown, the outer diameter of the middle tube 2 is greater than the outer diameter of the inner tube 3, and the outer diameter of the outer tube 1 is greater than the outer diameter of the middle tube 2. In this embodiment, when the outer diameter of the middle tube 2 is greater than the outer diameter of the inner tube 3 and the outer diameter of the outer tube 1 is greater than the outer diameter of the middle tube 2, the inner tube 3 can retract into the middle tube 2 when the internal thread II and the external thread II are unscrewed, and the middle tube 2 can retract into the outer tube 1 when the internal thread I and the external thread I are unscrewed, which is more convenient to carry.

[0020] As Figure 1 and Figure 2 shown, a rubber insulating handle 6 is sleeved on the outer tube 1. In this embodiment, the rubber insulating handle 6 can increase the friction between the hand and the outer tube 1 and prevent the operator from getting an electric shock.

[0021] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the scope defined by the spirit of the present invention.
