Description

Technical Field

[0001] The utility model relates to a wire clamp, in particular to a wire clamp with stable clamping capacity, and belongs to the technical field of power transmission line construction. Background Art

[0002] In the prior art, a utility model application numbered 201921780559.5 discloses a wire clamp. In order to solve the problem that the bearing capacity is poor after exceeding the load-bearing capacity, some parts may be easily bent or even broken due to metal fatigue during long-term use, the wire clamp is designed with two wire clamping grooves. When clamping thinner wires, a wire clamping groove with an arched barb strip can be used. When clamping thicker wires, a wire clamping groove with a straight barb strip can be used. The inclination direction of the barb is the pulling direction of the wire clamp. Direction, can effectively increase the friction between the wire, prevent sliding during clamping, increase the clamping capacity, the pressure arm in the control mechanism has more force points, and the force directions on both sides are opposite to those in the middle, so the pressure arm is thickened, and the arc-shaped outer surface can effectively enhance the force-bearing capacity, and the connection between the pressure arm and the upper clamp arm is moved to the inner protrusion, and the two sides of the protrusion are set to a concave arc structure, which can ensure the structural strength while effectively dispersing the force to the arc-shaped outer surface, reducing the possibility of bending deformation due to force and increasing service life.

[0003] Similar to the above application, there are still some deficiencies:

[0004] During the clamping process, if there is oil, dust or other debris on the surface of the wire, it is inconvenient to clean the surface of the wire, and it is also inconvenient to clean the clamping surface of the wire clamp during use. These substances will reduce the friction between the wire clamp and the wire, causing slippage;

[0005] Therefore, a wire clamping device with stable clamping is designed to optimize the above-mentioned problem. Utility Model Content

[0024] The overall working principle: during use, if there is oil or impurities on the surface of the wire, the arc groove 5 at the bottom of the lower clamp arm 3 is clamped on the wire. At this time, the cleaning cotton 6 on the inside of the arc groove 5 will contact the wire, and then the wire clamp is controlled to move along the wire to clean the stains on the surface of the wire, and then the device is installed. If there are stains inside the wire grooves on the lower clamp arm 3 and the upper clamp arm 4, use the cleaning mechanism to clean them. In addition, during the use of the wire clamp, the elastic reset effect of the torsion spring 15 is used to control the mutual fit of the lower clamp arm 3 and the upper clamp arm 4. In order to reduce the friction resistance between the pin shaft 11 at the end of the connecting rod 14 and the pressure plate 2, the lubrication mechanism 13 can be used to lubricate the inside of the shaft hole 12 to reduce the friction resistance encountered when the lower clamp arm 3 and the upper clamp arm 4 are closed.

[0025] In this embodiment, the cleaning mechanism includes a guide groove 7, a slider 8, an L-shaped plate 9 and a wiping sponge block 10. The guide groove 7 is opened on the outside of the lower clamp arm 3 and the upper clamp arm 4, and the guide groove 7 is parallel to the length direction of the wire groove. The inside of the guide groove 7 is slidably installed with a slider 8, and the slider 8 is rotatably installed with an L-shaped plate 9. The ends of the L-shaped plate 9 are installed with a wiping sponge block 10.

[0026] Local working principle: Rotate the L-shaped plate 9 close to the wire trough, the wiping sponge block 10 is located inside the wire trough, and then control the slider 8 to slide along the guide groove 7, and the wiping sponge block 10 evenly cleans the inside of the wire trough to ensure the installation stability of the wire clamp.

[0027] In this embodiment, the wiping sponge block 10 is arc-shaped, and the arc-shaped surface of the wiping sponge block 10 can fit the inner side of the wire groove.

[0028] Partial working principle: The wiping sponge block 10 can fit tightly inside the wire slot and evenly clean the inside of the wire slot.

[0029] In this embodiment, the lubrication mechanism 13 includes an external spiral tube 17, a drainage hole 18 and an extrusion assembly. The external spiral tube 17 is fixed to the top of the pressure plate 2. The top of the pressure plate 2 is provided with a drainage hole 18 that connects the axial hole 12 with the inside of the external spiral tube 17. The inside of the external spiral tube 17 is filled with grease, and the top of the external spiral tube 17 is provided with an extrusion assembly for discharging the grease.

[0030] Local working principle: Before use, apply grease to the inside of the outer screw tube 17 for storage. If the friction resistance between the pin shaft 11 and the pressure plate 2 is large, the grease can be injected into the inside of the shaft hole 12 through the drainage hole 18 through the extrusion component to lubricate the movable connection point.

[0031] In this embodiment, the extrusion assembly includes an inner nut 19, a fixing rod 20 and a rubber pressure cover 21. The inner nut 19 is threadedly connected to the outer screw tube 17. The fixing rod 20 is vertically fixed to the inner top of the inner nut 19. The rubber pressure cover 21 is fixed to the bottom end of the fixing rod 20. The rubber pressure cover 21 is slidably connected to the outer screw tube 17.

[0032] Partial working principle: When discharging the grease, the inner nut 19 is rotated to control the rubber gland 21 to move vertically inside the outer spiral tube 17, thereby squeezing out the grease.

[0033] In this embodiment, the outer side of the inner nut 19 is evenly provided with anti-slip grooves, and the anti-slip grooves are perpendicular to the horizontal plane.

[0034] Partial working principle: Through the setting of the anti-slip groove, the rotation of the inner nut 19 can be easily controlled manually, which is more practical and convenient.
