Detailed description of the invention
For making object of the invention process, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is further described in more detail.In the accompanying drawings, same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Described embodiment is the present invention's part embodiment, instead of whole embodiments.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.Below in conjunction with accompanying drawing, embodiments of the invention are described in detail.
In describing the invention; it will be appreciated that; term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear", "left", "right", " vertically ", " level ", " top ", " end " " interior ", " outward " etc. instruction orientation or position relationship be based on orientation shown in the drawings or position relationship; be only the present invention for convenience of description and simplified characterization; instead of instruction or imply indication device or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as limiting the scope of the invention.
Load bed traction switching mechanism provided by the invention, main purpose is release piece 1 is separated automatically with air-drop load bed 13, as shown in Figure 1, release piece 1 is provided with two towing pads in its one end away from air-drop load bed, is respectively extraction parachute rope connecting bore 9, and main chute rope connecting bore 10, connect extraction parachute rope and main chute rope respectively, the other end of release piece 1 is connected with air-drop load bed 13, when needed, can disconnect with described air-drop load bed 13, thus extraction parachute traction load bed is converted to traction main chute.Described traction switching mechanism comprises mounting seat 2, and its one end is fixed in described air-drop load bed 13, and it, away from one end opening slot of air-drop load bed 1, is convenient to dockingundocking part 1;
Release piece 1, as shown in Figure 1, its one end is provided with blind round hole to its concrete structure, and is arranged on by this end in the hole slot of described mounting seat 2; Described hole slot is provided with at the other end opening that diameter is less than described blind hole, in order to limit the device be arranged in described blind hole.In the present embodiment, refer to for limited piston bar.
Described piston rod 7, its one end is arranged in the blind round hole of described release piece 1, and the opening that the other end protrudes through above-mentioned diameter smaller stretches out hole slot, connection control mechanism afterwards;
Control mechanism, it is arranged to control the device that described piston rod 7 moves in the blind round hole of described release piece 1, wherein, release piece 1 can be controlled for making control mechanism to depart from air-drop load bed, at the present embodiment, concrete mechanism as shown in Figure 1, the blind hole side of release piece 1 has steel ball hole, the position that mounting seat 2 contacts with described blind hole side steel ball hole at it is provided with steel bead groove, described steel ball hole and described steel bead groove are embedded with steel ball, the blind-hole bottom of release piece 1 connects described piston rod 7 by spring, described piston rod 7 has two states under the effect of spring and control mechanism, first state, described steel ball is squeezed in described steel ball hole and described steel bead groove by described piston rod 7, second state, described piston rod 7 forms the space holding described steel ball in the blind round hole of described release piece 1.
Should be understood that, in this enforcement, described control mechanism comprises revolving bar 5, and pivotable is connected in described mounting seat 2, and by this junction, described revolving bar 5 is divided into two sections, first paragraph, contacts, second segment, unsettled placement with described piston rod 7.As seen from Figure 1, when extraction parachute is interconnected with air-drop load bed, the second segment of shown revolving bar 5 is perpendicular to horizontal surface, when dropping load bed and moving to the position of carrying roller 12, the second segment of revolving bar 5 is along with the continuation campaign of whole mechanism, will touch and beat bar roller 11, afterwards under the effect of pivotable connection, the first paragraph of the second segment driven rotary bar 5 of revolving bar 5 moves to the position of piston rod 7, drive piston rod 7 Compress Spring 8, make piston rod 7 be in the second state, and then make release piece 1 depart from air-drop load bed.
Should be understood that, the first view of piston rod 7 is given in Fig. 1, as can be seen from the figure, the position that piston rod 7 contacts with steel ball fills up whole blind hole, thus steel ball 3 is pressed in described steel ball hole and described steel bead groove, now dropping load bed is connected on described release piece by mounting seat 2, when piston rod 7 Compress Spring, when namely going to the second state by the first state, described piston rod 7 will vacate a part of space in blind hole, in order to deposit steel ball, be understandable that, under this kind of state, force is continued to release piece, due to the arcuate structure of steel bead groove, steel ball must be made to move in above-mentioned space, and then time release piece 1 depart from mounting seat 2.
For the process moderately gusty air vibrations preventing revolving bar 5 from moving in release piece traction air-drop load bed 13, described revolving bar is fixed by wire fuse, concrete, arbitrary place perforate on described revolving bar 5, wire fuse 6 passes this hole and ties a knot around mounting seat, described revolving bar 5 is fixed in mounting seat 2, prevents revolving bar 5 from swinging arbitrarily.
As described in Figure 2, the quantity of steel ball 3 is shown particular case and determines, and be such as set to 2-20, in the present embodiment, the quantity in described steel bead groove and steel ball hole is 4, is uniformly distributed circumferentially.
Be limited in described blind hole for making inventive piston bar 7, its device for limiting can be the opening part being set directly at one end, also opening diameter can be reduced at this opening part by installing other framing member, the present embodiment adopts the second preferred implementation, specifically see Fig. 1, the hole slot position of stretching out described mounting seat 2 in described piston rod 7 one end is provided with blanking cover 4, and described mounting means is various, and such as described blanking cover 4 takes outside thread mode to be arranged in mounting seat 2; Or described blanking cover 4 takes negative thread mode to be arranged in mounting seat 2.
Finally it is to be noted: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit.Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
