Detailed description of the invention
Fig. 1 is one structural schematic diagram of the utility model embodiment；
Fig. 2 is structure enlargement diagram at A in Fig. 1；
Fig. 3 is two structural schematic diagram of the utility model embodiment.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
A kind of anticreep fastener as shown in Figure 1 to Figure 3, including interconnecting piece 1 and outer connector 2, interconnecting piece 1 include interior
Bar 11 and the integrally formed square 12 that interior bar top is arranged in of interior bar 11,12 both ends of square are movably equipped with movable block 13, outside
Connector 2 includes the limiting section 22 on 21 top of outer bar 21 and outer bar, and outer bar 21 and limiting section 22 are goed deep into and be pierced by 21 bottom end of interior bar,
21 outer ring of interior bar for stretching out limiting section 22 is equipped with screw thread, and is fixed interior bar 21 and limiting section 22 by nut 3, spiral shell in interior bar 21
Female lower part is additionally provided with anti-delinking part.
Embodiment one: anti-delinking part includes Anti-separating telescopic block 41 and the spring connecting with Anti-separating telescopic block 41 42, Anti-separating telescopic
Block 41 is up big and down small back taper, and interior bar 11 is equipped with and the matched anticreep groove 43 of Anti-separating telescopic block 41, anticreep groove 43
Spring 42 is equipped between Anti-separating telescopic block 41.
One end of movable block 13 is equipped with extension bar 131, and the end outer ring of extension bar 131 is equipped with pars contractilis, square 12
Interior be equipped with holds the groove 121 of pars contractilis, pars contractilis include the protrusion 132 being arranged on extension bar 131 and with it is raised 132 matched
Projecting slot 133 is connected between protrusion 132 and projecting slot 133 by elastomeric element 134, and movable block can be removed out of square, convenient for tight
Firmware adapts to a variety of different environmental demands, expands the adaptation range of fastener.
Protrusion 132 is the outside triangle baffle in tip, and the slope of triangle plays guiding role, convenient for movable block with
The installation or removal of square, it is easy to operate.
Then interior bar need to passed through into outer bar and limiting section in 3 through-hole of workpiece by fastener by outer rod set, limited stretching out
Nut is installed in the interior bar in position portion, since Anti-separating telescopic block 41 is up big and down small back taper, there is certain guiding role, just
It is upwardly into nut through the bottom end spiral of interior bar and is in close contact with limiting section, and during nut screw is upward, work as nut
When oppressing Anti-separating telescopic block, Anti-separating telescopic block 41 and the spring 42 being connect with Anti-separating telescopic block 41, so that Anti-separating telescopic block is in spiral shell
It is retractable in anticreep groove under female external force, when nut bottom end all passes through Anti-separating telescopic block, Anti-separating telescopic block is without outer
