The specific embodiment

Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.

Embodiment 1

A kind of Yard bridge fitting, by hook 1, latch hook 3 is formed with latching device 5, and latching device 5 is positioned at the notch top of latch hook 3, and hook 1 passes latch hook 3 notches and is positioned at latching device 5 belows.Hook 1 is the L type; Guide groove 8 is positioned at hook 1 lower, bottom end; Pilot bar 2 is positioned at guide groove 8 and runs through latch hook 3 and connect in the inner left ends of guide groove 8, and bearing pin 7 is fixed in guide groove 8 right-hand members, and pilot bar 2 right-hand members are through bar spring 6 captive joint bearing pins 7; Latching device 5 is connected through hole spring 4 and two ends captive joint draw ring with the notch top of latch hook 3, and hook 1 touches with latch hook 3 notch toe joints.Latching device 5 is for fly-headed bolt and run through latch hook 3 tops.Latching device 5 is by screw 9, spring 10, steel ball 11; Locations 12 is formed with gear 13; Screw 9 screw threads are fixed in latch hook 3 tops and the lower end connects steel ball 11 through spring 10, and the groove of steel ball 11 bottoms and locations 12 upper surfaces coincide, gear 13 and the engagement of locations 12 lower recess.

A kind of Yard bridge fitting structure one, through on draw handle, make tooth and the tooth on the hook 1 on the handle be in non-engagement state; Promote hook 1, make the distance between hook 1 and the latch hook 3 reach necessary requirement, unclamp handle then; Handle realizes that the tooth on the handle is meshing with each other with the tooth on the hook 1 under the effect of hole spring 4 power, hook 1 and latch hook 3 are packed in the two adjacent container angles; On draw handle, make tooth and the tooth on the hook 1 on the handle be in non-engagement state, this moment, hook was under the effect of bar spring 6 power; Hook 1 shrinks mutually with latch hook 3, until pressing close to the corner fittings hole wall, unclamps handle; Handle is under the effect of hole spring 4 power, and its tooth and the tooth on the hook are meshing with each other, and realizes locking.

A kind of Yard bridge fitting structure two, the rotation fly-headed bolt makes it move back pine, regulates the distance between hook 1 and the latch hook 3, the corner fittings hole and tightening up of packing into, the fly-headed bolt of screwing then intermeshes the tooth between hook 1 and the latch hook 3, and realization is locked.

A kind of Yard bridge fitting structure three; Promote locations 12; Make the medial launder of locations 12 cooperate one to promote hook 1 and the bridge sign indicating number is packed in the corner fittings and tightened up one promote locations 12 with steel ball 11, the left groove of locations 12 is cooperated with steel ball 11, the bridge sign indicating number is in locking state at this moment.Its method for dismounting is: promote locations 12 medial launder is cooperated with steel ball 11, take off the bridge sign indicating number then.
