Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
The longitudinal locking mechanism capable of feeding back an unlocking in-place signal as shown in fig. 1 to 3 comprises a baffle 3, a rotating arm 5, a forward stop 8 and a spring 10; the rotating arm 5 is in a horizontal plate shape, the rear end of the rotating arm extends downwards and vertically, the baffle 3 and the rotating arm 5 are fixedly connected through an explosive bolt 1 positioned at the lower end of the rotating arm 5, and the baffle 3 is vertically fixed on a bottom plate 11 positioned below the rotating arm 5; the rotating arm 5 is provided with an upward bulge which can be rotationally fixed through the upward bulge; a forward stop dog 8 is fixed at the flat plate position on the rotating arm 5; the upper end of the spring 10 is fixed at the front end of the rotating arm 5, and the lower end is fixed at the front end of the bottom plate 11.
Two ends of the spring 10 are sleeved on the draw hooks 9, and the two draw hooks 9 are respectively fixed on the front surface of the front end of the rotating arm 5 and the upper surface of the front end of the bottom plate 11 in a threaded manner.
And a travel switch 7 is also fixed on the bottom plate 11.
A vertical protective plate 12 is also fixed to the bottom plate 11.
The protection plate 12 is fixed beside the travel switch 7 and is positioned between the travel switch 7 and the baffle 3.
The rotating arm 5 is rotatably fixed through a pin shaft 4.
A side plate 6 is further fixed at the position of the upward convex part of the rotating arm 5, and the side plate 6 is matched with a forward stop block 8 in a shape.
The forward stopper 8 passes through the upwardly protruding portion of the swivel arm 5 and is screw-fixed by the adjustment nut 2.
Therefore, the unlocking of the invention is controlled by the explosive bolt 1, and the unlocking in-place signal is fed back by the travel switch 7 after the unlocking in-place.
The backward constraint of the object is performed by the side plate 6; the forward restraint is carried out by a forward stop dog 8, the forward stop dog 8 is connected with the rotating arm 5, and the stress of the rotating arm 5 is borne by the pin shaft 4 and the baffle 3, so that the explosive bolt 1 is not stressed by tension, and the requirement on the bearing capacity of the explosive bolt 1 is not high.
The working process is as follows: as shown in figure 1, the baffle 3, the side plate 6 and the bottom plate 11 are welded into a whole to play a supporting role, the rotating arm 5 can rotate around the pin shaft 4, the forward stop block 8 is adjusted to ensure that the object to be restrained is reliably restrained when the baffle is closed, and meanwhile, the rotating arm 5 and the baffle 3 are reliably connected by tightening the explosion bolt 1 to prevent the rotating arm from rotating under the action of the spring 10. When the locking needs to be released, the explosion bolt 1 is started to enable the rotating arm 5 and the baffle 3 to be released from constraint, the forward stop block 8 and the rotating arm 5 rotate together around the pin shaft under the action of the spring 10 so as to release the forward constraint of the constrained object, meanwhile, the rotating arm 5 is in contact with the travel switch to enable the circuit to be conducted, an unlocking in-place signal can be fed back, and the constrained object can move forward.
