Detailed Description
As shown in fig. 1 and 2, a conical shaft hole 4 is formed in the lock body 2, a ball 5 and a spring 3 are arranged in the conical shaft hole 4, the lower end of the spring 3 is supported on the ball 5, the upper end of the spring 3 is supported on the top cover 1, the top cover 1 is fixed with the upper end of the lock body 2, and the top cover 1 is provided with an upper through hole 9 capable of accommodating two equal-diameter steel wire ropes 7; a bottom cover 8 is fixed at the lower end of the lock body 2, and a lower through hole 10 is formed in the bottom cover 8; two ends of a steel wire rope 7 enter from the lower through hole 10 and extend out from the upper through hole 9 through the taper shaft hole 4.
The top cover 1 and the lock body 2, and the bottom cover 8 and the lock body 2 are in interference fit.
The top cover 1 and the lock body 2, and the bottom cover 8 and the lock body 2 are fixed by screw threads.
And an arc chamfer 6 is arranged on the lower opening of the lower through hole 10, so that the steel wire rope can be prevented from being cut off when being tensioned.
The bottom cover 8 is provided with a long slotted hole 11 with two ends in arc shapes, and the long slotted hole 11 is in clearance fit with the two equal-diameter steel wire ropes 7, as shown in figures 3 and 5.
Two cylindrical holes 12 are formed in the bottom cover 8, and the two cylindrical holes 12 are in clearance fit with one equal-diameter steel wire rope 7 respectively, as shown in fig. 4 and 6.
The slot 11 is coaxial with the bottom cover 8, as shown in fig. 3.
The two cylindrical bores 12 are coaxial with the bottom cover 8, as shown in fig. 4.
The slot hole 11 is eccentric to the bottom cover 8, as shown in fig. 5.
The two cylindrical holes 12 are eccentric to the bottom cover 8, as shown in fig. 6.
When in use, the loop of the steel wire rope 7 is sleeved on the object to be bundled, and one end of the steel wire rope 7 is tensioned or simultaneously tensioned. When the steel wire rope 7 is subjected to the external bracing tension of the bound object, the friction force between the sphere 5 and the steel wire rope 7 drives the sphere 5 to move downwards, so that the sphere 5 locks the steel wire rope 7 under the action of the conical surface to achieve the locking effect.
When the steel wire rope can not be sleeved, one end of the steel wire rope 7 penetrates through the bundled object and then penetrates through the lower through hole 10, penetrates out of the upper through hole 9 through the taper shaft hole 4 and is tensioned.
