Problems solved by technology
[0002] Most of the existing airbag products such as emergency buoys and life rafts use flexible envelopes, and the flexible envelope skin is wrapped into the designed shape by means of fixed force ropes or fixed force rivets. Large, difficult to keep consistent with the appearance of the aircraft, and difficult to apply on high-speed aircraft, therefore, it is necessary to use a rigid container for airbag packaging
[0003] When using a rigid container for airbag packaging, it is necessary to solve the locking problem. Generally, the lock cylinder is changed to move and reset to complete the unlocked and locked state. However, for the sake of simplifying the structure, the airbag products are locked The power source of the device can only use the air source of the airbag product itself. Therefore, how to complete the movement and reset of the lock cylinder pneumatically, and design a pneumatic lock for airbag products with a simple structure is to complete the rigid container for the airbag. packet key

Embodiment Construction
[0018] Below in conjunction with accompanying drawing and embodiment the present invention is further described.
[0019] Such as figure 1 and figure 2 As shown, a pneumatic lock for an air bag product includes a lock cylinder 2, a lock case 1, a spring 5, a piston 6 and a ventilation line 4, the spring 5 and the piston 6 are both arranged in the lock case 1, and one side of the piston 6 is always subjected to The spring 4 pushes, and the other side is fixed with the piston rod 3. The piston rod 3 passes through the lock housing 1 in a sealed manner and always contacts the bottom of the lock cylinder 2. The top of the lock cylinder 2 is always located in the slot of the airbag product. The piston 6 The lock case 1 is divided into two chambers, the chamber where the spring 5 is located is provided with a vent 7, and the other chamber is connected to the vent pipe 4, the vent pipe 4 is connected to the gas source of the air bag product, and the piston rod 3 There are two step...

The invention relates to a pneumatic lock for an air bag product, which includes a lock cylinder, a lock case, a spring, a piston and a ventilating pipeline. Both the spring and the piston are arranged in the lock case, one side of the piston is always pushed by the spring, and the other side is fixed with a piston Rod, the piston rod seals out of the lock housing and is always in contact with the bottom of the lock cylinder. The top of the lock cylinder is always located in the slot of the airbag product. The piston divides the lock housing into two chambers. The chamber where the spring is located is set There is a ventilation port, and another cavity is connected with the ventilation pipeline, and the ventilation pipeline is connected with the gas source of the air bag products, and there are two steps on the piston rod. The pneumatic lock realizes the locking and unlocking of the lock cylinder, and has the advantages of simple structure, low cost, fast action and reliable transmission.
