Abstract
The utility model discloses a prevent artificially breaking out, including detaining the body and round pin axle, detain the body including U type member, U type member right -hand member head fixedly connected with nut, left end head fixedly connected with ring, a round pin axle left end passes the ring and is connected with the nut, and a round pin left end is equipped with rotating portion, rotating portion top is equipped with non -circular recess, and the outer edge of rotating portion is circular. The utility model provides an it needs to adopt the installation of special instrument and dismantles to break out, and consequently the unable rotating of common tool can effectively avoid the emergence of the improper dismantlement action of breaking out, avoids the passive protection net to be destroyed.
Description
Technical field
The utility model relates to the engineer applied technical field of side slope flexible protective screening, particularly relates to passive protection net system, is specially one and prevents artificially dismantling shackle.
Background technology
By highway and railway in the environment such as mountain region, river valley, the natural landing thing such as falling rocks, snowslide, mud-rock flow that occurs of the place such as side slope usually may cause serious harm and loss, particularly along mountain area side slope landing or the stone that falls, not only occur frequent but also be difficult to expect, generally adopt at present and protective screening is set in these locations and region, landing thing, falling object are stopped.Wherein passive type soft protecting net uses more a kind of protective screening, and existing passive protection host will use shackle to carry out the connection between each unit of system, although the shackle used at present is installed and dismantled more convenient, also there is easily stolen risk.
Utility model content
The purpose of this utility model is that providing a kind of prevents artificially dismantling shackle, and this shackle is not by common tool ejector, and effectively can prevent the behavior that passive protection net is destroyed, technical scheme is as follows:
One is anti-artificially dismantles shackle, and comprise button and bearing pin, described button comprises U-shaped rod member, and described U-shaped rod member right end is fixedly connected with nut, and left end head is fixedly connected with annulus; Described bearing pin passes annulus and is connected with nut, and bearing pin left end is provided with turn portion, and top, described turn portion is provided with non-circular groove, and the outer in turn portion is circular.
Further, described groove is polygon.
Further, described groove is oval.
Further, cylindricality key body is also provided with in described groove.
Further, described key body is cylinder.
The beneficial effects of the utility model are: the shackle that the utility model provides need adopt the installation and removal of special instrument, and general tool cannot turn, therefore effectively can avoid the generation of improper dismounting shackle behavior, avoid passive protection net to be destroyed.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further: as Fig. 1, shown in Fig. 2, one is anti-artificially dismantles shackle, comprise button 1 and bearing pin 2, described button 1 comprises U-shaped rod member 11, described U-shaped rod member 11 right end is fixedly connected with nut 13, and left end head is fixedly connected with annulus 12; Described bearing pin 2 passes annulus 12 and is connected with nut 13, and bearing pin 2 left end is provided with turn portion 21, and top, described turn portion 21 is provided with non-circular groove 22, and the outer in turn portion 21 is circular.
As shown in Figure 3, the shape of groove 22 can be polygon, as triangle or hexagon etc., also can be produced the shape of moment by turn groove 22 for other, as oval or any irregular shape.
When installing or removing, need to carry out with the instrument corresponding with groove 22 shape, and all cannot turn bearing pin 2 by free-hand or other common instruments, and by its removal from button 1, and then cannot by shackle from the online removal of passive protection, effectively prevent the generation of improper dismounting behavior, and then it is destroyed to avoid passive protection net.
Can also arrange the key body 23 of cylindricality in groove 22, as shown in Figure 4, key body 23 can be cylindrical or other arbitrary shapes.This structure is more strict to the tool demands of installation and removal, is more not easy to adopt other instruments substituted to operate.
