Put or element must be with specific orientation, with specific azimuth configuration and operation, therefore it is not intended that protecting to the present invention
The restriction of scope.
The load bed traction switching mechanism that the present invention is provided, main purpose are to make release piece 1 divide with air-drop load bed 13 automatically
From as shown in figure 1, release piece 1 is provided with two towing pads, respectively extraction parachute rope connection at which away from one end of air-drop load bed
Hole 9, and main chute rope connecting hole 10, connect extraction parachute rope and main chute rope respectively, and the other end of release piece 1 is connected with air-drop load bed 13
Connect, when needed, can disconnect with described air-drop load bed 13, traction main chute is converted to so as to extraction parachute traction load bed.Institute
The traction switching mechanism that states includes mounting seat 2, and its one end is fixed in the air-drop load bed 13, and which is away from air-drop load bed 13
One end opening slot, is easy 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 the end is arranged on the installation
In the hole slot of base 2；The hole slot is provided with opening of the diameter less than the blind hole in the other end, in order to limit installed in described
Device in blind hole.In the present embodiment, refer to for limiting piston rod.
The piston rod 7, its one end are arranged in the blind round hole of the release piece 1, and the other end protrudes through above-mentioned
The smaller opening of diameter stretches out hole slot, afterwards connection control mechanism；
Controlling organization, its are arranged to the dress for controlling the piston rod 7 to move in the blind round hole of the release piece 1
Put, wherein, for enabling controlling organization to control release piece 1 to depart from air-drop load bed, in the present embodiment, such as Fig. 1 institute of specific mechanism
Show, the blind hole side of release piece 1 has steel ball hole, mounting seat 2 is set in its position contacted with the blind hole side steel ball hole
Steel bead groove is equipped with, the steel ball hole is embedded with steel ball with the steel bead groove, the blind-hole bottom of release piece 1 is described by spring connection
Piston rod 7, the piston rod 7 is with two states, first state, the piston rod 7 in the presence of spring with controlling organization
The steel ball is squeezed in the steel ball hole and the steel bead groove, the second state, the piston rod 7 is in the release piece 1
The space for accommodating the steel ball is formed in blind round hole.
It should be appreciated that in this embodiment, the controlling organization includes swingle 5, is pivotably attached to the installation bottom
On seat 2, and the swingle 5 is divided into two sections by the junction, first paragraph, contact with the piston rod 7, second segment, hang
Empty placement.As seen from Figure 1, when extraction parachute is connected with each other with air-drop load bed, the second segment of shown swingle 5 is perpendicular to water
Plane, when the position that load bed moves to carrying roller 12 is dropped, the second segment of swingle 5 is with the continuation fortune of whole mechanism
Dynamic, it will to touch and beat bar roller 11, afterwards in the presence of being pivotally connected, the second segment of swingle 5 is rotated the of bar 5
Move at one section of position to piston rod 7,7 compression spring 8 of piston rod is driven, piston rod 7 is made in the second state, and then make to take off
Off member 1 departs from air-drop load bed.
It should be appreciated that the first state schematic diagram of piston rod 7 in Fig. 1, is given, it will be apparent from this figure that piston
Whole blind hole is filled up with steel ball at the position that bar 7 is contacted, so as to steel ball 3 is pressed in the steel ball hole and the steel bead groove,
Now air-drop load bed is connected on described release piece, when 7 compression spring of piston rod, i.e., by the first shape by mounting seat 2
When state goes to the second state, the piston rod 7 will vacate a part of space in blind hole, in order to deposit steel ball, it is possible to understand that
, under this kind of state, force is continued to release piece, due to the arcuate structure of steel bead groove, steel ball is necessarily made to above-mentioned sky
In motion, and then when release piece 1 depart from mounting seat 2.
For preventing swingle 5 from drawing during air-drop load bed 13 is moved, in release piece, vibrations of jolting, the swingle leads to
Cross fuse to be fixed, specifically, arbitrary place's perforate on the swingle 5, fuse 6 is through the hole and around mounting seat
Knot, so that the swingle 5 is fixed in mounting seat 2, prevent swingle 5 from arbitrarily swinging.
As described in Figure 2, depending on the quantity of steel ball 3 shows concrete condition, 2-20 is such as set to, in the present embodiment, described
Steel bead groove is 4 with the quantity in steel ball hole, is uniformly distributed circumferentially.
For making inventive piston bar 7 be limited in described blind hole, its device for limiting can be set directly at one end
At opening, it is also possible to reduce opening diameter by installing other structures part at the opening, the present embodiment is excellent using second
Embodiment is selected, Fig. 1 is specifically shown in, stretch out at the hole slot position of the mounting seat 2 in 7 one end of the piston rod and be provided with blanking cover
4, described mounting means is various, and such as described blanking cover 4 takes external screw thread mode in mounting seat 2；Or, described stifled
Lid 4 takes internal thread mode in mounting seat 2.
Last it is to be noted that：Above example only in order to technical scheme to be described, rather than a limitation.To the greatest extent
Pipe has been described in detail to the present invention with reference to the foregoing embodiments, it will be understood by those within the art that：Which is still
Technical scheme described in foregoing embodiments can be modified, or equivalent is carried out to which part technical characteristic and replace
Change；And these modifications or replacement, do not make the essence of appropriate technical solution depart from the essence of various embodiments of the present invention technical scheme
God and scope.
