The front pull plate 70 and the rear pull plate 74 are connected by rivets. The front pull plate 70 and the triangular pull plate 71 are connected by rivets. The rear pull plate 74 and the triangular pull plate 71 are connected by rivets. A groove is formed on the bottom surface of the tethering lock base plate 69. The front pull plate 70 and the rear pull plate 74 are opened to their maximum angle and inserted into the groove of the tethering lock base plate 69. The large stud 72 is then closed and closed to its minimum angle. A limiting pin 73 is inserted into the through hole between the front pull plate 70 and the rear pull plate 74 to prevent the front and rear pull plates from falling off the large stud 72.

[0066] The main working process of this tethered release facility is as follows:

[0067] 1) The initial installation status of this mechanism is shown in [reference]. Figure 1 and Figure 2 .

[0068] 2) Secure the components to the corresponding positions on the loading dock using bolts and nuts.

[0069] 3) During the initial mooring and securing of the mechanism, the longitudinal bar assembly is pulled backward, and the transverse bar assemblies are slid to both sides, resisting the pulling force of the mooring release strap on the vise assembly. The springs on both the longitudinal and transverse bars are compressed. During airdrop, the mechanism activates the pyrotechnic cutter in the longitudinal bar limiting assembly, causing the spring to spring back, thus moving the longitudinal bar assembly forward and the transverse bar assemblies laterally towards the cargo platform. The vise assembly opens its jaws, the mooring release strap loosens, and the left and right pull plates of the mooring lock open and fall, releasing the mooring between the airdrop equipment and the cargo platform.

[0070] This invention can achieve simultaneous action at multiple points and in multiple directions by increasing or decreasing the number of linear cams on the longitudinal rod and the number of crossbars.

[0071] This invention is primarily applied in my country's airdrop field. It enables the airdrop system and equipment to be securely fastened during air transport and to separate in mid-air after disembarkation. This airdrop system differs from other airdrop systems in that it not only requires the airdrop system and equipment to be securely fastened during air transport but also ensures that the airdrop equipment and airdrop system can be separated in mid-air after disembarkation.

[0072] This invention limits the installation position of the longitudinal and transverse bar assemblies on the cargo platform by using a support base; determines the overall height limit of the longitudinal and transverse bar assemblies by the installation position of the airdrop boat on the cargo platform; determines the mooring binding style by the reserved positions of the cargo platform pull ring assembly, vise assembly, and mooring lock on the airdrop boat, thus achieving mooring and securing of the airdrop system and airdrop equipment during air transport; determines the initial force value of the longitudinal bar by using a longitudinal bar limiting assembly; and solves the problem of aerial separation after airdrop by using the actuation of the pyrotechnic device of the longitudinal bar limiting assembly to release the entire mooring release mechanism.

[0073] The invention has undergone nearly 50 ground tests, and the test process was good. The spring force value was within the design range, the four points of operation were simultaneous and rapid, the reliability was high, and no faults such as sluggish operation or jamming occurred. It has basically achieved the expected results.
