The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail:

Like the hydraulic pressure locking bolt that suspends that Fig. 1-band signal shown in Figure 5 feeds back; Comprise lower platen 1, cover on top board 11 on the lower platen 1, be fixed on the lower platen 1 active latch hook 2 and from moveable lock hook 3, initiatively the below of latch hook 2 is provided with hydraulic ram 8, initiatively latch hook 2 is provided with the oil cylinder that contacts with the piston rod of hydraulic ram 8 and ejects projection 2.2; One side of hydraulic ram 8 is provided with locking signal transducer 9; Initiatively latch hook 2 is provided with the locking signal projection 2.1 that contacts with locking signal transducer 9, initiatively also is provided with locking projection 2.3 on the latch hook 2, is provided with the concave surface 3.1 that locks with locking projection 2.3 from moveable lock hook 3; Initiatively on the latch hook 2 first torsion spring 10 is installed; From moveable lock hook 3 second torsion spring 4 is installed, is equipped with groove 12 on lower platen 1 and the top board 11, the bottom surface of this groove 12 is concordant with concave surface 3.1.The bottom of lower platen 1 and top board 11 is equipped with damping rubber block 1.2.Hydraulic ram 8 belows are provided with support 7, and hydraulic ram 8 is installed on the support 7 with locking signal transducer 9.Oil cylinder ejects projection 2.2 and is arc surface.

Lower platen 1 connects into an integral body with top board 11 through riveting cover 5; Latch hook 2 and be arranged between lower platen 1 and the top board 11 initiatively from moveable lock hook 3; And be installed on the riveting cover 5; Can freely rotate, and by second torsion spring 4 and first torsion spring 10 restoring force after the rotation is provided respectively, hydraulic ram 8 and locking signal transducer 9 are riveted on the lower platen 1 through support 7 together.

During work, the upwards driving surface 2.1 of top active latch hook of oil cylinder 8 of unblanking, initiatively latch hook 2 integral body are overlapped clickwise around riveting, when 2.4 parts of active latch hook are got out of the way from moveable lock hook 3, under the effect of torsion spring 4, obtain to open from moveable lock hook 3; The gravity that relies on vehicle body self during locking is to 3.1 positions that press down driven latch hook; This moment, initiatively latch hook 2 blocked from moveable lock hook 3 in the effect of torsion spring 10, realized locking, and this moment, initiatively locking signal transducer 9 was depressed in the contact 2.1 of latch hook; Send the locking signal, on the bridge instrumentation dish, show locking.

As shown in Figure 3, damping rubber block 1.2 has been vulcanized in the lower platen 1 and top board 11 bottoms of the utility model, so that locking bolt is directly installed on the upper surface of air bag bumper, and can play the effect of damping.

Locking signal projection 2.1 contacts with locking signal transducer 9 after locking, will lock signal through locking signal transducer 9 and transfer to operator's compartment, conveniently checks locking state; Oil cylinder ejects projection 2.2 when unblanking, and contacts with hydraulic ram 8, and it is excessive that this contact point is designed to circular arc, and making it with the piston rod of hydraulic ram 8 is that line contacts, and has reduced friction drag, moves more flexible.

The content of not doing in this specification sheets to describe in detail belongs to this area professional and technical personnel's known prior art.
