Detailed Description

As shown in figures 1 to 4, the bolt looseness prevention wire locking pliers comprise a handheld pipe 1, wherein an anti-skidding knurl is arranged outside the handheld pipe 1, an ejector rod 2 is arranged in the handheld pipe 1, a circle of flange 11 is arranged in the handheld pipe 1, and a pressing handle 3 which is connected with one end of the handheld pipe 1 in a threaded mode pushes one end of the ejector rod 2 to abut against the flange 11. When the fuse needs to be installed on the screw, one end of the fuse can be inserted into the flange 11, then the pressing handle 3 is rotated, and the fuse is clamped through the ejector rod 2 and the flange 11.

The pressing handle 3 is in threaded connection with the hand-held tube 1 through a ratchet mechanism 5. The ratchet mechanism 5 can improve the knob efficiency of the fuse, so that the wire locking pliers are more convenient and reliable to use.

The ratchet mechanism 5 comprises a shaft hole 34 arranged in the pressing handle 3, a rotating shaft 58 arranged in the shaft hole 34, one end of the rotating shaft 58 is fixedly connected with a threaded part 59 arranged outside the shaft hole 34, a spline 56 is arranged in the middle of the rotating shaft 58, a square hole 33 communicated with the shaft hole 34 is arranged on the pressing handle 3, a first cut groove 32 with an inclined bottom surface is respectively arranged on the pressing handle 3 on two sides of the square hole 33, a T-shaped pressing plate 54 is respectively arranged in each first cut groove 32, a pressing strip 55 extends from one end of each pressing plate 54, the pressing strip 55 is clamped in a key groove of the spline 56, a shifting block 51 is arranged in the square hole 33, a convex part 52 is arranged on the surface of the shifting block 51, a bent elastic sheet 53 is fixedly connected to the bottom surface of the shifting block 51, and two ends of the elastic sheet; the sleeve 6 is sleeved outside the pressing handle 3, the sleeve 6 is provided with a strip-shaped hole 61, the protruding part 52 on the surface of the shifting block 51 penetrates through the strip-shaped hole 61, and the elastic sheet 53 can be shifted through the protruding part 52 and the shifting block 51 to simultaneously press the two pressing plates 54 or press one of the pressing plates 54 on the inclined plane of the first tangential groove 32.

The working principle of the ratchet mechanism 5 is as follows: as shown in fig. 1, when the shifting block 51 is used to push the elastic piece 53 to abut against one end of one of the pressure plates 54, the elastic piece 53 pushes one end of the pressure plate 54 to abut against the inclined surface of the first cut groove 32 and tilt, so that the pressing strip 55 connected with the pressure plate 54 is separated from the key groove of the spline 56, and the pressing strip 55 connected with one end of the other pressure plate 54 is still in the key groove of the spline 56, as shown in fig. 4, when the spline 56 is rotated, the spline 56 can only rotate in one direction under the matching of the pressing bar 55 in the key groove of the spline 56 and the pressing handle 3, and the ratchet effect is achieved; when the protruding part 52 is moved to the middle part of the strip-shaped hole 61, the elastic sheet 53 compresses the two pressing plates 54 at the same time, and the two pressing plates 54 are not in inclined surface contact with the first cut groove 32, so that the two pressing strips 55 fall into the key grooves of the spline 56 at the same time, and the spline 56 cannot rotate; the ratchet mechanism 5 with the structure has the advantages of simple structure, small volume, convenient disassembly and simple maintenance.

Set up an jack that is linked together with shaft hole 34 on compressing tightly handle 3, be equipped with inserted sheet 57 in the jack, inserted sheet 57 one end is equipped with the arc wall corresponding with the 58 external diameters of pivot, and pivot 58 sets up in the arc wall, spline 56 is close to screw portion 59 one side and supports and lean on inserted sheet 57. The tab 57 prevents the spline 56 from coming out of the hold-down shank 3.

The pressing handle 3 is provided with a counter bore, a pressing cover 8 and a first spring 81 are arranged in the counter bore, the surface of the pressing cover 8 is provided with a protrusion, the sleeve 6 is provided with a round hole, and the first spring 81 pushes the protrusion to enter the round hole. This structure is for the convenience of attaching and detaching the sleeve 6.

A second slot 50 is opened in the middle of the threaded portion 59, and the end of the top rod 2 away from the flange 11 has a conical insertion portion 21, and the insertion portion 21 is clamped in the second slot 50. After the threaded portion 59 is tightened, the top rod 2 pushes the threaded portions 59 on both sides of the second slot 50 to expand outwards through the conical insertion portion 21, so that the threaded portions 59 are tightly matched with the hand-held rod, and a certain anti-loosening effect is achieved.

The flange 11 and the mandril 2 are in conical fit. The conical surface can enlarge the clamping area of the safety guard and improve the clamping effect.

A through hole 31 is arranged at one end of the pressing handle 3, and a force application rod 4 is inserted into the through hole 31. Separable formula application of force pole 4 can further make things convenient for operating personnel knob lock wire pincers, also makes things convenient for the staff to accomodate lock wire pincers simultaneously.

A tapered hole is formed in the through hole 31, a second spring 71 and the steel ball 7 are arranged in the tapered hole, and the second spring 71 pushes one end of the steel ball 7 to be exposed out of the tapered hole and abut against the force applying rod 4. This structure can prevent the reinforcing bar 4 from falling out of the through hole 31.
