Labeled as: the anti-skid device comprises a lower pressing block 101, a first anti-skid strip 102, a hinge 103, an upper pressing block 104, a second anti-skid strip 105, a bump 106, a fixed cavity 107, a movable hole 108, a nut 109, a stud 110, a limiting block 111, a groove 112, a screwing block 113 and a limiting bolt 114.
Detailed Description
As shown in the figure, the inside and outside nylon chuck for the elevator comprises a lower pressing block 101, a first anti-skid strip 102, a hinge 103, an upper pressing block 104, a second anti-skid strip 105, a convex block 106, a nut 109, a stud 110, a limiting block 111 and a screwing block 113. The top end of one end of the lower pressing block 101 is connected with the top end of the other end of the upper pressing block 104 through a hinge 103, and the lower pressing block 101 and the upper pressing block 104 can rotate relatively. One ends of the lower pressing piece 101 and the upper pressing piece 104 close to the hinge 103 are symmetrically bent to form a fixed cavity 107. The inner side of the bent end of the lower pressing block 101 is transversely and uniformly provided with the first anti-slip strips 102, and the middle part of the inner side of the bent end of the lower pressing block 101 is provided with a groove 112. The inner side of the bent end of the upper pressing block 104 is transversely and evenly provided with a second anti-slip strip 105, and the middle part of the inner side of the bent end of the upper pressing block 104 is provided with a convex block 106. When the nylon rope is placed in the fixed cavity 107, the nylon rope is clamped by shortening the distance between the lower pressing block 101 and the upper pressing block 104, and the first antislip strip 102 and the second antislip strip 105 can increase friction force, so that the nylon rope is not easy to slide. The bump 106 and the groove 112 deform the nylon rope, effectively preventing the nylon rope from sliding.
One side of one end, far away from the hinge 103, of the lower pressing block 101, close to the upper pressing block 104 is fixedly provided with a stud 110 through welding, the stud 110 penetrates through a movable hole 108 formed in the upper pressing block 104 and extends to one side, far away from the lower pressing block 101, of the upper pressing block 104, and the inner diameter of the movable hole 108 is larger than the outer diameter of the stud 110, so that the upper pressing block 104 cannot be clamped when rotating relative to the lower pressing block 101. A nut 109 is fittingly mounted on a stud 110 extending to a side of the upper press block 104 remote from the lower press block 101, the outer diameter of the nut 109 being greater than the inner diameter of the movable hole 108 so that the nut 109 does not become jammed in the movable hole 108. The two sides of the nut 109 are welded with screwing blocks 113, and the nut 109 can be screwed manually through the screwing blocks 113. The end of the stud 110 far away from the lower pressing block 101 is welded with a limiting block 111, so that the nut 109 cannot slide and be lost.
Through holes are correspondingly formed in the lower pressing block 101 and the upper pressing block 104 which are positioned between the stud 110 and the fixing cavity 107, and limiting bolts 114 are installed in the through holes, so that the nylon ropes can be prevented from shifting.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
