Description

Locking and disengaging mechanism in conical disc form Technical Field The invention belongs to the field of umbrella bag strap systems, and particularly relates to a locking and disengaging mechanism in a conical disc form. Background The stable umbrella release lock of the active main and standby integrated umbrella bag strap system in China is a three-ring release mechanism and mainly comprises a large ring, a middle ring, a small ring, a rope buckle, a metal eye ring, a locking bolt and the like (see figure 1). The umbrella is positioned between the main umbrella and the backup umbrella bag, can be smoothly separated under different load working conditions, and has simple structural form. When the second-level umbrella opening stable umbrella works abnormally, the parachuting staff pulls the handle to drive the steel wire rope to be pulled out from the closed rope, the three rings are separated, and the stable umbrella is opened to form an umbrella bag. When the parachuting person uses the parachute opener to open the secondary parachute, the parachuting person works stably after leaving the machine, and the mechanical automatic parachute opener is used for opening the stable parachute to be separated from the lock. The active main and standby integrated umbrella bag straps in China are all used for locking the stable umbrella by using a three-ring release lock, and the position of the stable umbrella is arranged between the main umbrella bag and the standby umbrella bag. The umbrella bag is poor in integration caused by the structure, and when the stable umbrella works, the middle part of the umbrella bag is lifted, so that the umbrella bag is in a bow shape, and the faults that the disengaging lock is pressed by the umbrella bag and cannot be disengaged, the disengaging lock deflects to cause early disengaging and the like are easily caused. When the three-ring device is arranged at the tail part of the umbrella bag, the lifting point of the stable umbrella is deviated, and the balance of limbs of a parachuting person is kept in the air, if the posture is kept in place, the winding leg of the stable umbrella can be damaged, the requirement on the skill of the parachuting is high, and the stable umbrella is not suitable for the cluster parachuting of a large army. When the parachuting personnel uses the active main and standby integrated umbrella bag strap system to carry out secondary parachute opening and descending training, as the stable umbrella separating lock is positioned between the main umbrella bag and the standby umbrella bag, the structure causes poor umbrella bag integrity, and when the stable umbrella works, the middle part of the umbrella bag is lifted, so that the separating lock is easily pressed by the umbrella bag and cannot be separated, and the separating lock deflects to cause the faults of early separation and the like. Disclosure of Invention The invention aims to provide a locking and disengaging mechanism in a conical disc form, solve the problem of integration of an umbrella bag and improve the reliability of a system. The technical scheme includes that the locking and disengaging mechanism in the form of a conical disc comprises a conical disc, a connecting belt, a conical disc protective sleeve and a safety bolt, wherein the connecting belt penetrates through the conical disc and is fixed through a conical disc fixing pin and a conical disc fixing pin screw, the connecting belt is provided with the safety bolt, and the safety bolt on the connecting belt is used for packaging. The cone disc main body is of an integrated structure, the upper and lower shapes of the cone disc main body are disc-shaped with different sizes, the two discs are connected together in the middle, a through hole is formed in the middle of the two discs, two symmetrical round holes are formed in the side face of the middle of the disc, and the cone disc protective sleeve is sleeved on the large disc of the cone disc main body through the cone disc fixing pin. The middle part of the connecting belt is sewed with a hitching, a safety bolt is sewed at a certain distance on the upper part of the hitching, the connecting belt passes through a through hole on the conical disc main body, a conical disc fixing pin passes through a round hole on the upper side surface of the conical disc main body and the hitching at the middle part of the connecting belt, and then the conical disc fixing pin is fixed by a conical disc fixing pin screw. The upper end and the lower end of the connecting belt are respectively provided with a knot which can be sleeved with other devices. Compared with the prior art, the invention has the remarkable advantages that the conical disc structure hanging point is positioned above the waist of the parachuting, the body posture can be still kept when the parachuting leaves the machine in a small posture, the consistency with the training action of the active paratrooper is high, the pro
