Embodiment
Following examples are used to illustrate the utility model, but are not limited to the scope of the utility model.
Embodiment 1
Referring to Fig. 1~4, the catching device includes arresting fixed body 1 and arrests lever arm 3, arrests the rear end connection of fixed body 1
There is action bars 2, the front end for arresting fixed body 1 offers the catch lock chamber 10 for accommodating and arresting object limbs, arrests fixed body 1 as half
Circle, it is arc to arrest lever arm 3, arrests the chute 12 that the inner side of fixed body 1 offers arc, arrests lever arm 3 and slides setting
In chute 12, steel wire rope 4 is provided with the front opening of catch lock chamber 10, lever arm 3 is arrested in the end connection of steel wire rope 4.
Increase steel wire rope 4 at the inner side of catch lock chamber 10 or front opening, steel wire rope 4 touches when arresting object, can drive and arrest work
Swing arm 3 moves to the direction for closing catch lock chamber 10, finally pins other side, effectively avoids arresting self-locking before other side
Situation occurs, reliable operation, preferably protects people's police etc. to arrest the personal safety of implementation personnel.
The guiding trestle 5 of supporting steel-cable 4 is provided with the front end for arresting fixed body 1, guiding trestle 5 there can be a variety of shapes
Formula, the roller freely rotated can be set, the spigot surface of an arc can also be set to be contacted with steel wire rope 4, ensured
Steel wire rope 4 slides smooth in capture process.Broken window side plate 8 is provided with the outside for arresting fixed body 1, is adapted to the broken window when arresting to make
With.Zigzag barb 9 is additionally provided with broken window side plate 8, can be with significantly more efficient broken window.
In the present embodiment it is two to arrest lever arm 3 and be symmetricly set in the chute 12 for arresting the both sides of fixed body 1, steel wire rope
4 both ends are respectively fixedly connected with two and arrest lever arm 3.Free activity occurs in order to prevent from arresting lever arm 3, in the activity of arresting
