Abstract

A wedge-shaped, pulley extrusion type inflatable safe airbag clothing, has a wedge-shaped, pulley extrusion type aeration tank (24), an air valve, a thermoplastic polyurethane (TPU) airbag and a rope pulling module. The wedge-shaped, pulley extrusion type aeration tank (24) is fixed onto the TPU airbag through the nut of the air valve, a sealing ring and the air valve. One end of the rope pulling module is connected with a rapier handle type bolt (6), and the other end thereof is connected with a motorcycle. When the pulling force to the rapier handle type bolt (6) is up to 15-20 kgs, the rapier handle type bolt (6) is pulled out of the aeration tank (24) and is separated from the aeration tank (24). At the same time, the tip of an impact needle (4) pierces the cap of an air bottle (1). The gas of CO2 in the air bottle (1) passes through the air valve and is inflated into the TPU airbag. The inflating course is accomplished within 0.5 seconds. During accidents, the inflatable safe airbag clothing can protect critical parts of a user, such as the protothorax, the neck, the waist, the lumbar vertebra and the buttocks, and can effectively improve the safety of the user.

Description

Wedge-shaped, pulley-squeezing inflatable safety air smashing garment

The invention relates to a wedge-shaped and pulley-squeezing inflatable air-conditioner garment, belonging to the technical field of safety devices.

Background technique

Application No. 20091 0180943. 6 "A safety air 嚢 clothing" provides a safety air 嚢 clothing by jacket clothing, TPU pneumatic or PVC gas 嚢, gas wide door, gas wide door nut, lever inflatable tank , carabiner, pull ring, pull cord disconnector, latch, drawstring, mesh cylinder holder and striker fittings, lever mechanism and drawstring disconnector. The lever of the lever mechanism has an L or Z shape. At one end of the lever, a rotating hole is fixed on the base through a shaft. The contact at one end of the lever contacts the slot or the stop of the slider through the opening of the hole, and the lever is rotated by the hole. When the shaft rotates, the contact close to the shaft pushes the slider to move in the tunnel and the striker breaks through the cylinder, and the lever mechanism is complicated.

Summary of the invention

In order to overcome the deficiencies of the prior art structure, the present invention provides a wedge-shaped, pulley-squeezed inflatable safety air smashing garment.

The technical solution adopted by the invention to solve the technical problems thereof is as follows: a wedge-shaped, pulley-squeezing inflatable safety air smashing garment, comprising a wedge-shaped, pulley-squeezing inflatable can, a gas wide door, a TPU air bag and a drawstring Component

The wedge-shaped, pulley-squeezing gas cylinder comprises a gas cylinder, a base, a mesh cylinder holder and a striker fitting assembly, a sword-type bolt, and a pulley assembly;

The base has a hole communicating, the one end hole is adapted to the mesh cylinder seat, the other end is a cross hole, the first port of the cross hole is connected by a cover; the other end is connected with the hole of the mesh cylinder seat; The three ports lead to the outside of the base; the base has a side hole to connect the wide open door; the wide open door is connected to the TPU air bag. Reticulated cylinder holder and striker fitting assembly, including mesh cylinder holder, striker, seal ring, spring; the right end of the mesh cylinder holder has a hole and a hole at the left end connected through a vent hole, and the vent hole is surrounded by gas Bottle holder venting micropores,

The wall of the right end of the mesh cylinder holder has a vent hole communicating with the side hole of the base;

The outer diameter of the striker has a sealing groove and a sealing ring, and the left end of the striker is needle-shaped, and the outer diameter of the needle is connected with the outer diameter groove from the tip;

The outer sleeve of the striker has a spring.

The pulley assembly has left and right pulley assemblies; the left pulley assembly (or movable top block) connects the support shafts to the arms of the open cage, the support shaft connects the bearings, the bearings are located in the open cage, and the left pulley assembly is embedded in In the hole of the second port, one end is in contact with the striker; the right pulley assembly (or fixed shaft pulley) is a support shaft connecting bearing, and the two ends of the support shaft are connected to the base and located in the hole of the first port; The pin has a connecting end and a grip end, and the top end of the sword is wedge-shaped or pointed, and has grooves on both sides matching the arc of the shaft 7.

One end of the drawstring assembly is connected to the sword handle and the other end is connected to the motorcycle.

The wedge-shaped, pulley-squeezing aeration tank is fixed to the TPU air bag by means of a wide-mouth nut, a sealing ring and a wide air door.

The sword pin is inserted into the third port of the base, and the grooves on both sides of the sword pin are respectively in contact with the bearing; when the sword pin is pulled out of the base, the sword pin squeezes the left pulley assembly in the cross hole The middle movement impacts the striker, causing the striker to break the seal of the gas cylinder. The pressure gas in the gas cylinder passes through the right end hole of the mesh cylinder holder and the gas cylinder seat to vent the micro hole, and then flows through the vent hole and the side hole of the base to the gas wide door. .

The wedge-shaped, pulley-squeezed pneumatic safety clothing is the principle of wedge-shaped extrusion pressure. The working principle is that the driver pulls the pulling force away from the motorcycle when the motorcycle driver hits the motorcycle and encounters an accident. Pull out the sword-type latch (starting bolt) set in the "wedge-shaped, pulley-squeezing aeration tank" by pulling. Assume Two pulleys placed inside the plastic base. One fixed shaft is set on one side, and one side is set on the movable top block. When the sword-type bolt is pulled, the fixed shaft pulley bears against the tail end of the sword-type bolt, and the tail end of the sword-type bolt is offset to squeeze the top block pulley, the top block Squeeze the striker. When the tension of the sword-type bolt reaches 15-20 kg, the sword-type bolt is passively pulled out and disengaged from the gas-filled can, and the needle tip breaks the gas cap, and the gas cylinder fills the CO2 gas into the TPU gas through the gas wide door. Pack, 0. 5 seconds to complete the inflation.

The invention has the beneficial effects that the wedge-shaped and pulley-squeezing aerated tanks are safe and reliable, start sensitive and simple in structure. The wedge-shaped and pulley-squeezed inflatable safety air-seal clothing has good integrity. The TPU air bag surrounds the upper body of the human body. It is light in weight, easy to install, comfortable to wear and breathable. Can be equipped with any style of jacket clothing. When the user encounters an accident, it can protect the front part of the chest, neck, waist, waist, hips, etc., effectively improving the safety of the user.
