Description

Technical Field

[0001] The present application relates to the technical field of electrical engineering, and particularly to a live access device. Background Art

[0002] In electrical engineering such as power emergency projects and power maintenance projects, power is taken from a power supply device to supply power to a device to be powered. In electrical engineering, the construction environment is mostly harsh, which is disadvantageous for construction workers. Traditional live access devices are mostly combined workpieces. When in use, the body of the live access device needs to be initially aligned with the power supply device, and with the tightening action of a fastening device, the contact area between the body of the live access device and the power supply device is tightly connected. Due to the harsh working environment, such combined workpiece devices are inconvenient to carry, greatly increasing the load of electrical workers. Specifically, after the fastening device of the body of the live access device fastens the body, it basically has no other use, which also causes waste of human resources. Therefore, it is necessary to propose a live access device to address the defect that traditional live access devices require a separate fastening device, exacerbating the burden on workers. Summary of the Utility Model

[0004] The present application relates to one kind, including:

[0005] A clamping seat, including a first sub-seat, a second sub-seat, and a guide rod. The guide rod is disposed between the first sub-seat and the second sub-seat.

[0006] A conductive tube, provided with a chute cavity, a receiving groove, a threaded cavity, and a clamping cavity. The first end of the conductive tube is sleeved inside the receiving hole.

It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0025] This application provides a live - access device.

[0026] As Figure 1 shown, in an embodiment of this application, a live - access device includes a clamping seat 100, a conductive tube 200, a load - bearing rod 300, a connecting body 400, a protective shell 500 and a rotating handle 600.

[0027] The clamping seat 100 includes a first sub - seat 110, a second sub - seat 120 and a guide rod 130. The guide rod 130 is arranged between the first sub - seat 110 and the second sub - seat 120. The first sub - seat 110 is provided with a card - placing hole 111, the second sub - seat 120 is provided with a receiving hole 121.

The first sub - seat 110 is further provided with a card - placing groove 112, and the card - placing groove 112 is arranged close to the card - placing hole 111.

[0028] As Figure 2 shown, the conductive tube 200 is provided with a chute cavity 210, a receiving groove 220, a threaded cavity 230 and a card - placing cavity 240. The first end of the conductive tube 200 is sleeved inside the receiving hole 121. The chute cavity 210 is communicated with the receiving groove 220. The second end of the guide rod 130 is slidably sleeved inside the chute cavity 210. The first sub - seat 110 is slidably arranged inside the inner cavity of the receiving groove 220, and the guide rod 130 is arranged inside the inner cavity of the receiving groove 220.

[0029] The load-bearing rod 300 is provided with a clamping portion 310, a threaded portion 320 and a riveting portion 330. The clamping portion 310 is arranged near the first end of the load-bearing rod 300. The riveting portion 330 is arranged near the second end of the load-bearing rod 300. The threaded portion 320 is arranged near the riveting portion 330. The clamping portion 310 is clamped in the clamping groove 112. The threaded portion 320 is in threaded connection with the threaded cavity 230. The riveting portion 330 abuts against the inner wall of the clamping cavity 240.

[0030] The connecting body 400 is riveted to the riveting portion 330. A rectangular surface 410 is arranged on the outer wall of the connecting body 400.

[0031] The protective shell 500 is sleeved on the outer surface of the conductive tube 200.

[0032] The rotating handle 600 is sleeved on the outer surface of the connecting body 400. The inner cavity of the rotating handle 600 is clamped in the rectangular surface 410. The rotating handle 600 is hinged to the protective shell 500.

[0033] This application relates to a live access device. By the first sub-seat 110 and the second sub-seat 120 of the clamping seat 100 approaching each other, the first sub-seat 110 and the second sub-seat 120 clamp and hold the power supply row of the power supply device. The guide rod 130 plays a guiding role in the process of the first sub-seat 110 and the second sub-seat 120 approaching each other, reducing the probability of the first sub-seat 110 and the second sub-seat 120 deviating from the predetermined track. The conductive tube 200 is used as a conductive device and is electrically connected to the clamping seat 100 through the accommodating hole 121. This solves the defect that the traditional live access device requires a separate fastening device, which increases the burden on the staff. More specifically, the load-bearing rod 300 is arranged in the inner cavity of the conductive tube 200. The outer wall of the load-bearing rod 300 is in threaded engagement with the inner cavity of the conductive tube 200. When the load-bearing rod 300 is rotated, the load-bearing rod 300 moves along the extension line of the central axis of the conductive tube 200, thereby realizing the mutual engagement or separation of the first sub-seat 110 and the second sub-seat 120, and reducing the auxiliary equipment of the live access device. The live access device does not require a separate fastening device, reducing the burden on the staff.

[0034] As Figure 2 shown, in an embodiment of the present application, the live access device further includes a first clamping tooth 710 and a second clamping tooth 720. The first clamping tooth 710 and the second clamping tooth 720 have the same structure. The first clamping tooth 710 is fixedly connected to the first sub-seat 110. The second clamping tooth 720 is fixedly connected to the second sub-seat 120.

[0035] Specifically, the first card - setting tooth 710 is fixedly connected to the first sub - seat 110, and the second card - setting tooth 720 is fixedly connected to the second sub - seat 120. When the first sub - seat 110 and the second sub - seat 120 approach each other, both the first card - setting tooth 710 and the second card - setting tooth 720 can bite the contact area of the power device, ensuring the tight connection between the contact area of the power device and the live access device.

[0036] In an embodiment of the present application, the first card - setting tooth 710 includes a substrate 711, a first buckle 712, and a second buckle 713. The first buckle 712 is fixedly connected to the substrate 711. The first buckle 712 is perpendicular to the substrate 711. The second buckle 713 is fixedly connected to the substrate 711. The second buckle 713 is perpendicular to the substrate 711. The first buckle 712 is parallel to the second buckle 713.

[0037] Specifically, the first buckle 712 and the second buckle 713 have the same size and structure, and the first buckle 712 and the second buckle 713 are commonly and perpendicularly connected to both sides of the substrate 711. The first buckle 712 and the second buckle 713 can bite the contact area of the power device with the same biting force.

[0038] In an embodiment of the present application, the first card - setting tooth 710 further includes a plurality of first base teeth 714 and a plurality of second base teeth 715. Each first base tooth 714 is fixedly connected to the substrate 711. Each first base tooth 714 is perpendicular to the substrate 711. Each second base tooth 715 is fixedly connected to the substrate 711. Each second base tooth 715 is perpendicular to the substrate 711. Each first base tooth 714 is parallel to each second base tooth 715.

[0039] In an embodiment of the present application, the first base tooth 714 and the second base tooth 715 have the same structure. The end face of the first base tooth 714 away from the substrate 711 is parallel to the substrate 711. The first buckle 712 and the second buckle 713 are both on the same side of the substrate 711. The first base tooth 714 and the second base tooth 715 are both on the same side of the substrate 711. The first buckle 712 and the first base tooth 714 are on opposite side walls of the substrate 711.

[0040] Specifically, the first buckle 712 is arranged between the first base tooth 714 and the substrate 711, and the first buckle 712 is fixedly connected to the first base tooth 714. The second buckle 713 is arranged between the second base tooth 715 and the substrate 711, and the second buckle 713 is fixedly connected to the second base tooth 715. The first base tooth 714 and the second base tooth 715 can be embedded into the contact area of the power device, enhancing the tight connection between the contact area of the power device and the live access device.

[0041] In an embodiment of the present application, a first notch 721 is provided on one side of the first sub-base 110 close to the second sub-base 120. The first clamping tooth 710 is clamped in the first notch 721. A second notch 722 is provided on one side of the second sub-base 120 close to the first sub-base 110. The first clamping tooth 710 is clamped in the second notch 722.

[0042] Specifically, the first clamping tooth 710 is mutually clamped with the first sub-base 110 by using the first notch 721. The second clamping tooth 720 is mutually clamped with the second sub-base 120 by using the second notch 722. The first clamping tooth 710 and the second clamping tooth 720 can be fixedly connected to the first sub-base 110 and the second sub-base 120 with relatively high strength.

[0043] As Figure 1 shown, in an embodiment of the present application, an inner ring groove 730 is provided at one end of the protective shell 500 close to the rotating handle 600. A snap spring 740 is clamped in the inner ring groove 730. The snap spring 740 abuts against the bottom edge of the clamping cavity 240; the end face of the conductive tube 200 coincides with the bottom edge of the clamping cavity 240.

[0044] Specifically, the protective shell 500 clamps the snap spring 740 through the inner ring groove 730. The protective shell 500 is sleeved on the outer surface of the conductive tube 200 and abuts against the conductive tube 200 through the snap spring 740. The protective shell 500 provides a force application point for the operator to hold the conductive tube 200.

[0045] When the load-bearing rod 300 rotates relative to the conductive tube 200, the conductive tube 200 remains stationary under the action of the force application point.

[0046] As Figure 2 shown, in an embodiment of the present application, a plurality of tenon clamps 750 are provided on the inner wall of the rotating handle 600. Each tenon clamp 750 is clamped in the rectangular surface 410. A color ring 760 is connected to the outer wall of the rotating handle 600.

[0047] Specifically, the protective shell 500 sleeved on the outer surface of the conductive tube 200 is hinged to the rotating handle 600 sleeved on the outer surface of the rotating handle 600. That is, the protective shell 500 and the rotating handle 600 can rotate relative to each other.

[0048] When the tenon clamp 750 of the rotating handle 600 is clamped in the rectangular surface 410 of the connecting body 400, the connecting body 400 can be relatively fixed to the rotating handle 600, providing a force application site for the operator to rotate the load-bearing rod 300.

[0049] As Figure 1As shown, in an embodiment of the present application, a locking groove 770 is provided at one end of the connector 400 away from the riveting portion 330. The locking groove 770 is used to hold the power transmission cable. The connector 400 is further provided with a cable accommodating groove 780. The cable accommodating groove 780 is provided away from the riveting portion 330.

[0050] Specifically, the connector 400 holds the power transmission cable by providing the cable accommodating groove 780 and the locking groove 770. This helps to improve the connection tightness between the power transmission cable and the live access device.

[0051] As Figure 3 As shown, in an embodiment of the present application, the live access device further includes a protective housing 800. The protective housing 800 is sleeved on the outer surface of the clamping seat 100. The protective housing 800 is sleeved on the outer surface of a preset portion of the conductive tube 200. The chute cavity 210 is provided in the preset portion of the conductive tube 200.

[0052] Specifically, the first sub-seat 110 and the second sub-seat 120 have a relatively high voltage and can release a large current to the ground in the working state. Therefore, an insulating silicone protective housing 800 is sleeved on the entire outer peripheral surface of the clamping seat 100, which helps to improve the electrical safety protection level of the device.

[0053] The technical features of the above-described embodiments can be combined arbitrarily, and there is no limitation on the execution order of the method steps. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0054] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the patent scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
