Description

Technical Field

[0001] The utility model relates to the technical field of wires, in particular to a wire shielding cover. Background Art

[0002] Wire refers to the material used for wires and cables, and also refers to wires in industry. It is generally made of copper or aluminum. Copper wire or aluminum wire can also be made of silver wire (good conductivity and thermal properties), which is used to conduct current or heat.

[0003] When inspecting and repairing the wires, it is necessary to use a shielding cover to cover the wires to ensure the safety of the workers when performing live operations. The existing shielding covers are generally directly buckled on the wires, and the shielding covers and the wires are not fixed. This causes the shielding covers to slide on the wires easily when the wires are tilted or shaken, thereby exposing the wires that should be shielded, posing a hidden danger to the safety of the workers. At the same time, when the length of the wire to be shielded is long, the workers are required to connect multiple shielding covers and push the shielding covers on the wires. However, the more shielding covers are connected, the greater the force of the workers to push the shielding covers, which is time-consuming and labor-intensive and reduces the installation efficiency of the shielding covers. Therefore, a wire shielding cover is proposed to solve the above problems. Utility Model Content

[0024] Furthermore, the inner walls of the upper arc-shaped cover body 3 and the lower arc-shaped cover body 1 are fixedly connected with symmetrical storage blocks 7, one end of the storage block 7 is provided with a storage groove, and an extrusion spring 701 is arranged in the storage groove, one end of the extrusion spring 701 is fixedly connected with an extrusion block 8 which is slidably connected to the storage groove, and one end of the extrusion block 8 is provided with a semicircular groove (the wire in the arc-shaped cover body is fixedly limited by the extrusion block 8).

[0025] It should be noted that: an extrusion fixing assembly is provided in the upper arc-shaped cover body 3, and the extrusion fixing assembly includes a plurality of fixing blocks 10 fixedly connected to the inner wall of the upper arc-shaped cover body 3 and symmetrically arranged, a hidden groove is provided at one end of the fixing block 10, a fixing spring 1002 is provided in the hidden groove, one end of the fixing spring 1002 is fixedly connected to a trapezoidal fixing member 11 slidably connected to the hidden groove (the trapezoidal fixing member 11 squeezes and fixes the wire), a through groove is provided at one end of the fixing block 10, and an installation groove is provided at one end of the trapezoidal fixing member 11, a connecting shaft 1101 is fixedly connected in the installation groove, and a pulley 12 is rotatably connected to the surface of the connecting shaft 1101 (the pulley 12 can facilitate the movement of the arc-shaped cover);

[0026] The surface of the upper arc-shaped cover body 3 is provided with a plurality of sliding grooves connected to the through grooves, in which a connecting plate 1001 fixedly connected to the trapezoidal fixing member 11 is slidably connected, a movable groove is provided at the top of the connecting plate 1001, and a movable plate 4 slidably connected to the movable groove is provided at the top of the plurality of connecting plates 1001 (the movable plate 4 is slidably connected to the connecting plate 1001, thereby facilitating the movement of the trapezoidal fixing member 11 and the connecting plate 1001).

[0027] It is worth noting that: a symmetrical circular hole is opened at one end of the movable plate 4, a bidirectional screw 5 is arranged in the circular hole, a pair of symmetrical nut blocks 501 fixedly connected to the circular hole are threadedly connected to the surface of the bidirectional screw 5, and a handle 502 is fixedly connected to the surface of the bidirectional screw 5 (the handle 502 enables the bidirectional screw 5 to rotate, thereby driving the nut block 501 and the trapezoidal fixing piece 11 to move, thereby squeezing and fixing the wire).

[0028] A further benefit of adopting the above method is that the above device fixes the arc cover and the wire, thereby preventing the arc cover from sliding on the wire when the wire is tilted or shaken, thereby avoiding exposure of the wire that should be shielded, ensuring the safety of the staff, and facilitating the movement of the arc cover through the pulley 12, saving time and effort while improving the installation efficiency of the arc cover.

[0029] When the utility model is in use: when it is necessary to install the device on the wire, the staff first rotates the upper arc cover 3 to open the device, and then places the lower arc cover 1 under the wire, and makes the extrusion block 8 contact the wire, and then the staff rotates the upper arc cover 3, and when the mounting plate 6 contacts the trapezoidal limit block 902, the trapezoidal limit block 902 will be squeezed, so that the trapezoidal limit block 902 shrinks into the connecting block 9, and when the upper arc cover 3 and the lower arc cover 1 are fitted, the limit spring 901 drives the trapezoidal limit block 902 to reset, so that the cross plate 2 and the mounting plate 6 are stuck, and the installation connection between the upper arc cover 3 and the lower arc cover 1 is realized;

[0030] During the rotation of the upper arc-shaped cover 3, the fixing block 10 drives the trapezoidal fixing piece 11 to contact the wire and is squeezed into the fixing block 10 by the wire. At the same time, the elastic force of the fixing spring 1002 drives the trapezoidal fixing piece 11 to move, so that the trapezoidal fixing piece 11 contacts the wire. Then the staff holds the handle 502 and rotates the handle 502. The rotation of the handle 502 drives the bidirectional screw 5 to rotate. The rotation of the bidirectional screw 5 drives the nut block 501 and the moving plate 4 to move. After sliding a certain distance, the moving plate 4 pushes the connecting plate 1001 to move, thereby stretching the fixing spring 1002 and giving a driving force to the trapezoidal fixing piece 11, so that the trapezoidal fixing piece 11 generates a fixed squeezing force on the wire, thereby fixing the arc-shaped cover and the wire.

[0031] When multiple such devices need to be installed, the staff drives the bidirectional screw 5 to reverse through the handle 502, so that the extrusion pressure brought by the movable plate 4 to the trapezoidal fixing piece 11 and the wire disappears, and then the staff pushes the upper arc cover 3 and the lower arc cover 1 to move the arc cover on the wire, which is convenient for the staff to install other arc covers. At the same time, the pulley 12 can facilitate the staff to push the arc cover more easily. The above-mentioned device fixes the arc cover and the wire, so as to prevent the arc cover from sliding on the wire when the wire is tilted or shaken, thereby avoiding the wire that should be shielded from being exposed, ensuring the safety of the staff, and facilitating the movement of the arc cover through the pulley 12, saving time and effort while improving the installation efficiency of the arc cover.
