[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0024] like Figure 1 , Figure 4 As shown, an anti-slip vibration-proof hammer comprises a connecting piece 1, a wire body 2 is arranged in the middle part of the upper end of the connecting piece 1, and an anti-slip clamp 3 is arranged on the outer wall of the wire body 2. The anti-slip clamp 3 enables the device to prevent the vibration-proof hammer from moving in the direction of the wire body, thereby avoiding the defect that the vibration-proof hammer slides on the conductor and / or ground wire and affects the vibration-proof effect. The interior of the connecting piece 1 is embedded with a movable groove 4, and the inner wall of the movable groove 4 is detachably connected with a clamping mechanism 5. The clamping mechanism 5 enables the device to improve the structure of the vibration-proof hammer, and can effectively solve the problem that the vibration-proof hammer installed on the ground wire is prone to slip after long-term work, reducing safety hazards, and the structure is simple, convenient and practical. The lower end of the connecting piece 1 is embedded with a fixed groove 6, and the bottom wall of the connecting piece 1 is movably connected with a steel strand 7, and hammer heads 8 are fixedly connected on both sides of the steel strand 7. The outer wall of the wire body 2 is plugged into the inner wall of the upper end of the connecting piece 1, and the outer walls of the wire body 2 are plugged into the inner walls of the anti-slip clamp 3 on both sides.
[0025] like Figure 2 As shown, the anti-slip clamp 3 includes a rigid member 31, the inner wall of the rigid member 31 is movably connected to the outer wall of the wire body 2, the outer wall of the rigid member 31 is provided with an opening 1 32, the inner wall of the rigid member 31 is provided with a flexible member 33, and the outer wall of the flexible member 33 is provided with an opening 2 34;
[0026] The outer wall of the rigid member 31 is provided with an opening 32, and the inner wall of the rigid member 31 is fixedly plugged with the outer wall of the flexible member 33;
[0027] The inner diameter of the rigid part 31 is the same as the outer diameter of the flexible part 33 and they are in contact with each other.
[0028] As can be known from the above, the second opening 34 is used to wrap the wire and / or the ground wire through the second opening 34 , and the setting of the first opening 32 is used to wrap the flexible member 33 around the wire and / or the ground wire through the first opening 32 .
[0029] like Figure 3 As shown, the clamping mechanism 5 includes a clamping plate 51, the outer wall of the clamping plate 51 is slidably connected to the inner wall of the movable groove 4, a hexagonal countersunk hole 52 is provided at the middle of the upper end of the clamping plate 51, a screw 53 is provided on the inner wall of the hexagonal countersunk hole 52, a nut sleeve 54 is threadedly connected to the bottom of the outer wall of the screw 53, an elastic sheet 55 is fixedly connected to the outer wall of the nut sleeve 54, and a screw head 56 is clamped and connected to the lower end of the nut sleeve 54;
[0030] The middle part of the upper end of the clamping plate 51 is embedded and connected with the bottom of the outer wall of the hexagonal countersunk hole 52, and the inner wall of the hexagonal countersunk hole 52 is plugged with the outer wall of the screw rod 53;
[0031] The elastic pieces 55 are perpendicular to the end surface of the screw head 56 , and are radially distributed along the circumference of the screw head 56 and inclined toward the tightening direction of the screw head 56 .
[0032] As can be seen from the above, the inner side of the clamping plate 51 is provided with anti-skid patterns, which are engraved patterns that roughen the inner surface of the guide clamping plate 51, thereby increasing the friction coefficient between the clamping portion and the steel strand 7.
[0033] The working principle of the utility model is as follows: first, the connector 1 contacts the wire body 2 through the flexible member 33, so that the wire body 2 can have a larger friction coefficient, and the flexible member 33 is fixed on the wire body 2 through the rigid member 31, so that the contact between the wire body 2 and the flexible member 33 is closer, so that the connector 1 can be more stably fixed on the wire body 2 through the rigid member 31 and the flexible member 33, the flexible member 33 is a tubular structure, and is made of rubber material, and at the same time, the side of the flexible member 33 is provided with an opening 34 in a direction parallel to the central axis of the flexible member 33, the opening 34 passes through both ends of the flexible member 33, and the opening 34 passes through the upper and lower ends of the flexible member 33, the rigid member 31 is a tubular structure, and is made of metal, and the rigid member 3 An opening 32 is provided on the side surface of 1 in a direction parallel to the central axis of the rigid member 31, and the opening 32 passes through the two ends of the rigid member 31. Then, when installing, the elastic sheet 55 can be bent and deformed by the anti-vibration hammer under the action of manpower and pass through the flanges on both sides of the inner wall of the fixing groove 6 to complete the fastening of the screw head 56. The deformation force of the elastic sheet 55 that needs to be overcome when tightening the screw head 56 is reduced, and the deformation force of the elastic sheet 55 that needs to be overcome when loosening the screw head 56 is increased. In the working state, the force in the loosening direction of the screw head 56 generated by the guide shaking or the wind force is very small, which is not enough to make the elastic sheet 55 bend and deform through the flange, so there is no need to worry about the problem of slippage of the steel strand 7 due to the loosening of the screw rod 53 after the anti-vibration hammer works for a long time.
[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
