Specific embodiment
As shown in Figures 1 to 4, a kind of anticreep fastener, the adapter sleeve 2 including bolt 1 and annular, on the screw rod of bolt 1
Equipped with external screw thread, the inner wall of adapter sleeve 2 is equipped with internal screw thread, and adapter sleeve 2 is connect with screw flight.Along length on the screw rod of bolt 1
It spends direction and is equipped with card slot 11, adapter sleeve 2 is equipped with the jack 21 for extending radially through adapter sleeve 2, is equipped with inserted block 3 in jack 21, inserts
The thickness of block 3 is matched with the width of card slot 11, and when adapter sleeve 2 is installed on screw rod, jack 21 faces card slot 11, inserted block 3
It can be inserted in card slot 11 and protrude into jack 21, to connect card slot 11 and jack 21, and then limit 2 phase of adapter sleeve
Screw rod is rotated, prevents adapter sleeve from loosening；The lateral wall of adapter sleeve 2 be equipped with indent fixed ring 22, fixed ring 22 and insert
Hole 21 is connected, and rubber ring 4 is equipped in fixed ring 22, and rubber ring 4 compresses inserted block 3 from outside, prevents inserted block 3 out of jack 21
It falls off.
As shown in figure 3, jack 21 includes that the mounting portion 211 interconnected and preset portion 212, mounting portion 211 are droped to the ground
Oval structures, specifically, mounting portion 211 include the first arc end 2111 and the second arc end 2112, the first arc end 2111
Radius of curvature less than the second arc end 2112 radius of curvature；Preset portion 212 is rectangular configuration, and preset portion 212 is located at second
The right side of arc end 2112, and its center line and mounting portion 211 are located on same level center line, the width in preset portion 212
With the thickness matching of inserted block 3.When adapter sleeve 2 rotates on screw rod, inserted block 3 is horizontally stuck in the preset portion 212 of jack 21,
Adapter sleeve 2 is followed to rotate together；After 2 clamping workpiece of adapter sleeve, inserted block 3 is taken out out of preset portion 212, by it in mounting portion
Vertical state is rotated into 211, is inserted into card slot 11, and the upper and lower ends of inserted block 3 are stuck in the first arc end 2111 at this time
With the junction of the second arc end 2112.The radius of curvature of second arc end 2112 is greater than the curvature half of the first arc end 2111
Diameter facilitates inserted block 3 to rotate in mounting portion 211.
As shown in figure 3, the hole wall in preset portion 212 is equipped with plating magnetosphere 213, inserted block 3 is magnet block.Inserted block 3 is to adapter sleeve 2
Limit it is preposition in preset portion 212, inserted block 3 can be adsorbed in preset portion 212, be firmly secured in preset portion 212.
As shown in figure 3, the length in preset portion 212 be less than inserted block 3 length, thus the left end of inserted block 3 can stretch out it is preset
It is taken out out of preset portion 212 using the left end for easily grabbing inserted block 3 when inserted block 3 in portion 212.
