Description

Technical Field

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

[0002] The grounding wire is a wire that is directly connected to the earth. It can also be called a safety return line. When there is danger, it transfers the high voltage directly to the earth. It is considered a lifeline. Due to poor insulation performance or humid operating environment, household appliances will have a certain amount of static electricity on their outer casing. In severe cases, electric shock accidents may occur. In order to avoid accidents, a wire can be connected to the metal casing of the appliance and the other end of the wire can be connected to the ground. Once the appliance leaks electricity, the grounding wire will bring the static electricity to the earth and release it.

[0003] A Chinese patent with announcement number CN211404780U discloses a portable grounding wire, including a hand-held rod, a clamping head and a conductive wire. Although the portable grounding wire described in the above patent can achieve reliable connection between the grounding wire and the high-voltage wire with the help of the clamping head when in use, when the clamping head is fixed to the high-voltage wire, there is no reliable limiting structure between the clamping head and the high-voltage wire, which causes the clamping head to be easily misaligned with the high-voltage wire when it is locked and fixed with the high-voltage wire, so that the high-voltage wire cannot be accurately located in the limiting groove after locking due to the skewness of the clamping head relative to the high-voltage wire, thereby reducing the locking area between the high-voltage wire and the clamping head, and causing the high-voltage wire to easily shake relative to the clamping head when used after locking.

[0005] The technical problem to be solved by the utility model is to provide a portable grounding wire which can avoid the skew and misalignment of the hanging plate relative to the high-voltage line when docking with the high-voltage line, and ensure the reliable connection between the hanging plate and the high-voltage line.

[0006] (II) Technical solution

[0007] The utility model is implemented through the following technical scheme: the utility model proposes a portable grounding wire, including a connecting wire, one end of the connecting wire is connected to a connecting member 2 through a conductive sheet, the connecting member 2 includes a hanging plate, a pre-clamping assembly installed at the top end of the hanging plate, a locking plate installed in the hanging plate and located at the lower side of the pre-clamping assembly, a screw rod rotatably installed in the middle of the bottom end of the locking plate, a turning handle installed at the bottom end of the screw rod, and a grip tube fixed at the bottom end of the hanging plate and located on the outside of the screw rod, wherein the pre-clamping assembly includes a rubber clamping block installed in the middle of the top end of the hanging plate, a limiting top plate symmetrically installed on both sides of the bottom end of the rubber clamping block, and a spring rod installed between each limiting top plate and the inner wall of the hanging plate.

[0008] Furthermore, the conductive sheet is connected to the hanging plate via bolts, and the connecting wire is connected to the hanging plate via a clamp.

[0009] By adopting the above technical solution, the conductive sheet and the connecting wire can be reliably installed and fixed on the hanging plate to avoid falling off.

[0010] Furthermore, the locking plate is slidably connected to the hanging plate, and the screw rod is rotationally connected to the locking plate.

[0011] By adopting the above technical solution, it can be ensured that the locking plate is conveniently lifted relative to the hanging plate during the rotation and lifting process of the screw rod.

[0012] Furthermore, the screw rod passes through the bottom of the hanging plate and is threadedly connected to the hanging plate, the screw rod passes through the grip tube, and a gap is reserved between the outer wall of the screw rod and the inner wall of the grip tube.

[0013] By adopting the above technical solution, holding the grip tube to rotate the handle can save the tedious operation of holding the hanging plate to adjust the locking plate when docking with the high-voltage line, making the docking and fixing of the hanging plate and the high-voltage line more convenient.

[0014] Furthermore, the rubber clamp is bonded to the hanging plate, the middle part of the bottom end of the rubber clamp is provided with a limiting groove, the spring rod is welded to the limiting top plate and the hanging plate, and the bottom end of the limiting top plate is an inclined structure facing the limiting groove on the rubber clamp.

[0015] By adopting the above technical solution, when connecting with the high-voltage line, the high-voltage line is first extended into the hanging plate and the high-voltage line is located at the inclined surface of the limiting top plate. Then, the hanging plate only needs to be pulled downward, and the limiting top plate can be retracted to the side away from the rubber clamp during the pulling process. After the high-voltage line is clamped into the rubber clamp, the limiting top plate is automatically reset with the help of the spring rod, so that the high-voltage line is pre-limited in the rubber clamp.

[0016] Furthermore, the connecting wire is connected to a connector 1 at one end away from the conductive sheet, and the connector 1 includes a fixed clamp block, a T-shaped locking bolt threadedly installed in the middle of one side wall of the fixed clamp block, and a movable clamp block installed at one end of the T-shaped locking bolt.

[0022] In order to solve the problem that the existing portable grounding wire can use the clamping head to achieve reliable connection between the grounding wire and the high-voltage wire when in use, but when the clamping head is fixed to the high-voltage wire, there is no reliable limiting structure between the clamping head and the high-voltage wire, which leads to the high-voltage wire being unable to be accurately located in the limiting groove after locking due to the skew and misalignment of the clamping head relative to the high-voltage wire when the clamping head is locked and fixed with the high-voltage wire, thereby reducing the locking area of ​​the high-voltage wire and the clamping head, and making the high-voltage wire easy to shake relative to the clamping head when used after locking. The utility model installs a pre-clamping component in the second connecting member, so that when the grounding wire is connected to the high-voltage wire, the rubber clamping block, the spring rod and the limiting top plate in the pre-clamping component can be pre-limited, effectively avoiding the relative skew and misalignment of the hanging plate when it is docked and fixed with the high-voltage wire, ensuring that the high-voltage wire can be accurately located in the limiting groove provided on the rubber clamping block after being installed on the hanging plate, avoiding the disadvantage that the high-voltage wire is easy to shake relative to the clamping head when used after locking.

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] like Figure 1-Figure 3 As shown, a portable grounding wire in this embodiment includes a connecting wire 2, one end of the connecting wire 2 is connected to a connecting piece 3 through a conductive sheet 4, and the connecting piece 3 includes a hanging plate 301, a pre-clamping assembly 302 installed at the top of the hanging plate 301, a locking plate 303 installed in the hanging plate 301 and located at the lower side of the pre-clamping assembly 302, a screw 305 rotatably installed in the middle of the bottom end of the locking plate 303, a handle 306 installed at the bottom end of the screw 305, and a gripping tube 304 fixed to the bottom end of the hanging plate 301 and located outside the screw 305. Holding the gripping tube 304 to rotate the handle 306 can save the tedious operation of holding the hanging plate 301 to adjust the locking plate 303 when docking with the high-voltage line, making the docking and fixing of the hanging plate 301 and the high-voltage line more convenient. The middle pre-clamping assembly 302 includes a rubber block 3021 installed in the middle of the top end of the hanging plate 301, a limiting top plate 3023 symmetrically installed on both sides of the bottom end of the rubber block 3021, and a spring rod 3022 installed between each limiting top plate 3023 and the inner wall of the hanging plate 301. When connected to the high-voltage line, the high-voltage line is first extended into the hanging plate 301 and the high-voltage line is located at the inclined surface of the limiting top plate 3023. Then, the hanging plate 301 only needs to be pulled downward to shrink the limiting top plate 3023 to the side away from the rubber block 3021 during the pulling process. After the high-voltage line is stuck in the rubber block 3021, the limiting top plate 3023 is automatically reset with the help of the spring rod 3022, so that the high-voltage line is pre-limited in the rubber block 3021.

[0030] like Figure 1-Figure 3 As shown, in this embodiment, the conductive sheet 4 is connected to the hanging plate 301 by bolts, and the connecting wire 2 is connected to the hanging plate 301 by a clamp, so that the conductive sheet 4 and the connecting wire 2 can be reliably installed and fixed on the hanging plate 301 to avoid falling off. The locking plate 303 is slidingly connected to the hanging plate 301, and the screw 305 is rotationally connected to the locking plate 303, which can ensure that the locking plate 303 is conveniently lifted relative to the hanging plate 301 during the rotation and lifting process of the screw 305.

[0031] like Figure 1-Figure 3As shown, in this embodiment, the screw 305 passes through the bottom of the hanging plate 301 and is threadedly connected to the hanging plate 301, the screw 305 passes through the grip tube 304, and a gap is reserved between the outer wall of the screw 305 and the inner wall of the grip tube 304, the rubber block 3021 is bonded to the hanging plate 301, and the rubber block 3021 has a limiting groove in the middle of the bottom end, the spring rod 3022 is welded to the limiting top plate 3023 and the hanging plate 301, and the bottom end of the limiting top plate 3023 is opposite to the limiting groove on the rubber block 3021, which is a slope structure.

[0032] like Figure 1-Figure 3 As shown, in this embodiment, the end of the connecting wire 2 away from the conductive sheet 4 is connected to a connector 1, and the connector 1 includes a fixed clamp block 101, a T-shaped locking bolt 102 installed in the middle of one side wall of the fixed clamp block 101 by means of a thread, and a movable clamp block 103 installed at one end of the T-shaped locking bolt 102. When the plug rod pre-fixed on the ground is located in the fixed clamp block 101, the movable clamp block 103 can be clamped on the ground plug rod by simply rotating the T-shaped locking bolt 102, so as to achieve reliable limiting of the ground plug rod between the fixed clamp block 101 and the movable clamp block 103. The movable clamp block 103 is slidably connected to the fixed clamp block 101, and the movable clamp block 103 is rotatably connected to the T-shaped locking bolt 102, which can ensure the stable sliding of the movable clamp block 103 relative to the fixed clamp block 101.

[0033] The specific implementation process of this embodiment is as follows: when in use, first place the pre-fixed plug rod on the ground between the movable clamp block 103 and the fixed clamp block 101, and rotate the T-lock bolt 102 to realize the clamping and fixing of the movable clamp block 103 and the fixed clamp block 101 to the ground plug rod. Then, when connecting with the high-voltage line, first extend the high-voltage line into the hanging plate 301, and make the high-voltage line located at the inclined surface of the limiting top plate 3023. Then, just pull the hanging plate 301 downward, and the limiting top plate 3023 can be retracted to the side away from the rubber block 3021 during the pulling process. Until the high-voltage line is stuck in the rubber block 3021, the spring rod 3022 is used to realize the automatic resetting of the limiting top plate 3023, so that the high-voltage line can be in the rubber block 3021. The pre-limiting is performed inside, and then the screw 305 is rotated by holding the grip tube 304, so that the locking plate 303 can be reliably pressed against the limiting top plate 3023 during the rotation of the screw 305 to ensure that the hanging plate 301 is reliably connected to the high-voltage line. Because the grounding wire of this structure is first pre-limited under the action of the rubber block 3021, the spring rod 3022 and the limiting top plate 3023 in the pre-clamping assembly 302 when being connected to the high-voltage line, the relative skewness and misalignment of the hanging plate 301 when being docked and fixed with the high-voltage line is effectively avoided, ensuring that the high-voltage line can be accurately located in the limiting groove on the rubber block 3021 after being installed on the hanging plate 301, thereby avoiding the disadvantage that the high-voltage line is easy to shake relative to the clamping head when used after being locked.
