[0002] Copper-clad flat steel grounding pieces are grounding workpieces with a copper layer plated on the surface of flat steel. Copper-clad flat steel grounding pieces have good corrosion resistance, high conductivity and other properties. Copper-clad flat steel grounding pieces mainly introduce fault currents of power equipment and lines into the earth to avoid the risk of electric shock and equipment damage due to poor grounding. Existing grounding pieces still have certain defects when used.

[0003] In the prior art, the grounding piece is usually directly inserted into the ground, and the wire and the grounding piece are connected by a connecting sleeve and fixed by bolts. Since the locking bolts require tools, it is difficult to fix the wire and the grounding piece. Utility Model Content

[0004] The utility model aims to provide an oxidation-resistant copper-clad flat steel grounding piece to solve the problem of troublesome fixation between the grounding piece and the conductor in the current market as mentioned in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oxidation-resistant copper-clad flat steel grounding piece, comprising: a grounding piece body, a connecting sleeve, a wire and a slide groove, the outer side of the grounding piece body is sleeved with a connecting sleeve, the inside of the connecting sleeve is penetrated and inserted with a wire, the slide groove is opened in the connecting sleeve, a fixed block is welded on the outer side of the connecting sleeve, a threaded rod is penetrated and connected to the inside of the fixed block through a bearing, a moving block is threadedly connected to the outer side of the threaded rod, a sliding rod is welded on the side of the moving block close to the connecting sleeve, an arc-shaped clamping block is welded to the ends of the two sliding rods, and limiting blocks are welded on both sides of the arc-shaped clamping block close to the slide groove.

[0006] Preferably, a sliding structure is formed between the limit block and the connecting sleeve via a sliding groove, and two groups of sliding rods are symmetrically arranged about the center of the arc-shaped clamping block.

[0007] Preferably, a sliding structure is formed between the sliding rod and the connecting sleeve.

[0008] Preferably, a connecting ring is sleeved on the bottom end of the grounding member body, and a protrusion is bonded to the inner wall of the connecting ring.

[0009] Preferably, a conical block is connected to the bottom of the connecting ring, and an antioxidant film is sprayed on the surface of the grounding member body.

[0010] Preferably, the protrusion is made of rubber material.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the anti-oxidation copper-clad flat steel grounding piece first inserts the wire into the connecting sleeve, and places the wire against the outside of the grounding piece body; when the threaded rod rotates, it can drive the moving block to slide in the direction of the wire; when the moving block slides, it can drive the two groups of sliding rods to move; while the sliding rods slide, it can drive the arc-shaped clamping block to move in the direction of the wire; when the arc-shaped clamping block moves, it can drive the two groups of limit blocks to move at the same time; the conical block at the bottom of the connecting ring can quickly insert the grounding piece body into the soil; the antioxidant film can improve the oxidation resistance of the grounding piece body, thereby preventing the grounding effect of the grounding piece body from being disturbed.

[0012] 1. The grounding piece can prevent safety accidents such as short circuit and fire caused by insulation damage or leakage of electrical equipment. Usually, it is troublesome to fix the grounding piece body and the wire. First, insert the wire into the connecting sleeve, and place the wire against the outside of the grounding piece body. When the threaded rod rotates, it can drive the moving block to slide in the direction of the wire. When the moving block slides, it can drive the two sets of sliding rods to move. At the same time, the sliding rod can drive the arc clamping block to move in the direction of the wire. When the arc clamping block moves, it can drive the two sets of limit blocks to move at the same time. When the limit block moves, it can slide through the slide groove. When the inner wall of the arc clamping block moves to the outer edge of the wire, the arc clamping block can squeeze the wire. When the wire is squeezed, it can be close to the grounding piece body. Through this simple and convenient method, the wire and the grounding piece body can be quickly limited and fixed.

[0013] 2. Although the copper-clad flat steel grounding piece has good corrosion resistance and high conductivity, the copper on the surface of the grounding piece body is prone to oxidation over a long period of time, which leads to a poor grounding effect of the grounding piece body. For this reason, an antioxidant solution can be sprayed on the surface of the grounding piece body to form a layer of antioxidant film on the surface of the grounding piece body. The antioxidant film can prevent oxygen from contacting the copper on the surface of the grounding piece body, thereby preventing the grounding piece body from further oxidation reaction. After the bottom end of the grounding piece body is inserted into the connecting ring, the bottom end of the grounding piece body can be inserted into the connecting ring. The conical block at the bottom of the connecting ring can quickly insert the grounding piece body into the soil. The antioxidant film can improve the oxidation resistance of the grounding piece body and avoid interference with the grounding effect of the grounding piece body. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 , Figure 2 and Figure 5 It can be seen that the utility model provides a technical solution: an oxidation-resistant copper-clad flat steel grounding piece, comprising: a grounding piece body 1, a connecting sleeve 2, a conductor 3 and a slide groove 4;

[0022] The outer side of the grounding member body 1 is provided with a connecting sleeve 2, and the inside of the connecting sleeve 2 is penetrated and inserted with a wire 3;

[0023] The slide groove 4 is opened inside the connecting sleeve 2, and a fixed block 5 is welded on the outside of the connecting sleeve 2. The inside of the fixed block 5 is connected with a threaded rod 6 through a bearing, and the outer side of the threaded rod 6 is threadedly connected with a moving block 7. A sliding rod 8 is welded on the side of the moving block 7 close to the connecting sleeve 2, and an arc-shaped clamping block 9 is welded together at the ends of the two sliding rods 8. Limiting blocks 10 are welded on both sides of the arc-shaped clamping blocks 9 close to the slide groove 4. A sliding structure is formed between the limiting block 10 and the connecting sleeve 2 through the slide groove 4. Two groups of sliding rods 8 are symmetrically arranged about the center of the arc-shaped clamping block 9, and a sliding structure is formed between the sliding rod 8 and the connecting sleeve 2.

[0024] During specific implementation, the grounding piece can prevent safety accidents such as short circuit and fire caused by insulation damage or leakage of electrical equipment. Usually, it is troublesome to fix the grounding piece main body 1 and the wire 3. First, insert the wire 3 into the connecting sleeve 2, and place the wire 3 against the outside of the grounding piece main body 1. At this time, the threaded rod 6 can be rotated. When the threaded rod 6 rotates, it can drive the moving block 7 to slide in the direction of the wire 3. When the moving block 7 slides, it can drive the two sets of sliding rods 8 to move. When the sliding rod 8 moves, it can slide with the connecting sleeve 2. At the same time as the sliding rod 8 slides, it can drive the arc clamping block 9 to move in the direction of the wire 3. When the arc clamping block 9 moves, it can simultaneously drive the two sets of limit blocks 10 to move. When the limit block 10 moves, it can slide through the slide groove 4. When the inner wall of the arc clamping block 9 moves to the outer edge of the wire 3, the arc clamping block 9 can squeeze the wire 3. When the wire 3 is squeezed, it can be close to the grounding piece main body 1.

[0025] See also Figure 1 , Figure 2 and Figure 5 It can be known that the conductor 3 and the grounding component body 1 can be quickly limited and fixed in this simple and convenient way.

[0026] See also Figure 1 , Figure 3 and Figure 4 It can be seen that a connecting ring 11 is sleeved on the bottom end of the grounding component body 1, a protrusion 12 is bonded to the inner wall of the connecting ring 11, a conical block 13 is connected to the bottom of the connecting ring 11, an antioxidant film 14 is sprayed on the surface of the grounding component body 1, the protrusion 12 is made of rubber material, and a plug-in structure is formed between the grounding component body 1 and the connecting ring 11.

[0027] During specific implementation, although the copper-clad flat steel grounding piece has good corrosion resistance and high conductivity, the copper on the surface of the grounding piece main body 1 is prone to oxidation over a long period of time, which leads to a poor grounding effect of the grounding piece main body 1. For this reason, an antioxidant solution can be sprayed on the surface of the grounding piece main body 1, so that a layer of antioxidant film 14 can be formed on the surface of the grounding piece main body 1. The antioxidant film 14 can prevent oxygen from contacting the copper on the surface of the grounding piece main body 1, thereby preventing the grounding piece main body 1 from further oxidation reaction. At the same time, the bottom end of the grounding piece main body 1 can be inserted into the connecting ring 11. After the bottom end of the grounding piece main body 1 is inserted into the connecting ring 11, the grounding piece main body 1 can squeeze the protrusion 12, which is made of rubber, so that the bottom end of the grounding piece main body 1 can be inserted into the connecting ring 11, and the conical block 13 at the bottom of the connecting ring 11 can quickly insert the grounding piece main body 1 into the soil.

[0028] See also Figure 1 , Figure 3 and Figure 4It can be known that the antioxidant film 14 can improve the oxidation resistance of the grounding component body 1 and prevent the grounding effect of the grounding component body 1 from being disturbed.

[0029] To sum up, when using the anti-oxidation copper-clad flat steel grounding piece, the wire 3 is fixed on the outside of the grounding piece body 1, and then the grounding piece body 1 is inserted into the soil. The wire 3 can be grounded through the grounding piece body 1, thereby introducing the fault current of the power equipment and the line into the earth, avoiding the risk of electric shock and equipment damage due to poor grounding. The copper-clad flat steel grounding piece is a prior art and will not be described in detail here. When the inner wall of the arc-shaped clamping block 9 moves to the outer edge of the wire 3, the arc-shaped clamping block 9 can squeeze the wire 3. When the wire 3 is squeezed, it can be close to the grounding piece body 1. Through this simple and convenient method, the wire 3 and the grounding piece body 1 can be quickly limited and fixed. The conical block 13 at the bottom of the connecting ring 11 can quickly insert the grounding piece body 1 into the soil. The antioxidant film 14 can improve the oxidation resistance of the grounding piece body 1 to avoid interference with the grounding effect of the grounding piece body 1.
