Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 to 6, an embodiment of the present invention includes:

a bullet pin comprising: the gas cylinder comprises a needle head 1 and a needle seat 2 matched with the needle head 1, wherein one end part of the needle head 1, which is exposed out of the needle seat 2, is a sharp angle, the other end of the needle head 1 is connected with the needle seat 2, the sharp part of the sharp angle is contacted with the opening of a gas cylinder 6 to puncture a sealing cover at the opening of the gas cylinder 6, the gas pressure in the gas cylinder 6 impacts an inclined plane of an inclined angle of a bullet needle to rebound the bullet needle, and the gas in the gas cylinder 6 is exhausted from the gas cylinder 6 through a gas outlet punctured by the sealing cover in the shortest.

Preferably, the sharp angle is an acute angle, which is easier to penetrate into the sealing cover of the opening of the gas cylinder 6 and can quickly rebound the bullet needle, and the optimal angle of the sharp angle is 30-70 degrees.

The needle seat 2 comprises a needle seat body 21 and a needle seat base 22, the lower end face of the needle seat body 21 is connected with the needle seat base 22, and the needle seat base 22 is used for concentrated stress when the elastic device 7 pushes the elastic needle and can prevent friction of repeated use.

The up end of needle seat body 21 sets up mounting hole 3, with the other end cooperation of syringe needle 1, the other end of syringe needle 1 can insert mounting hole 3, sets up the screw hole on the other end of syringe needle 1 and is used for other modes fixed connection such as needle seat body 21 or rises and tightly.

Set up ring channel 4 on the lateral wall of needle holder body 21, ring channel 4 is perpendicular with the axis of needle file 2, set up sealing washer or other sealing device in the ring channel 4, resilient means 7 promotes the bullet needle along the sealed lid of motion channel 8 forward motion until syringe needle 1 punctures the gas cylinder 6 bottleneck, the bullet needle is rebounded by gas pressure in the gas cylinder 6, when the bullet needle stops, the sealing washer seals motion channel 8 and seals, guarantee that whole gas in the gas cylinder 6 inflates along the gas charging hole of gasbag clothes, can be full of the gasbag clothes rapidly, and the protection performance is improved.

The bullet needle relies on the elastic thrust of the elastic device 7 to move, so the elastic device 7 is in a compressed state before the bullet needle is popped out, the bullet needle positions the elastic device 7 in a compressed state, the positioning groove 5 is arranged on the side wall of the needle seat body 21, preferably, the positioning groove 5 is a spherical groove, a groove matched with the spherical groove is arranged on the corresponding position of the side wall of the moving channel 8, when the spherical groove is in the same position with the groove of the side wall of the moving channel 8, the spherical positioning piece 9 is placed in the groove, fixes the bullet needle, and simultaneously limits the compressed state of the elastic device 7.

When a rider has an accident, the spherical positioning part 9 is pulled out, due to the elastic force, the elastic device 7 pushes the elastic needle to puncture the sealing cover at the opening of the gas cylinder 6, the elastic needle rebounds under the pressure of gas in the gas cylinder 6, the elastic needle blocks the motion channel 8, gas in the gas cylinder 6 is rapidly discharged out of the gas cylinder 6 from the punctured gas outlet of the sealing cover, and the gas cylinder is full of gas bag clothes along the gas charging hole for protection.

The utility model discloses bullet needle's beneficial effect is: the utility model provides a bullet needle sets up the top structure of bullet needle for the angle of setting for, has injectd the size that the bullet needle punctures the bottleneck when contacting with the gas cylinder bottleneck for the bullet needle can be popped out by gas pressure in the gas cylinder in the twinkling of an eye after puncturing the bottleneck, has increased the gas cylinder gas vent, has guaranteed that gas discharges in the gas cylinder in the shortest time, is full of the gasbag rapidly, has advantages such as reliable performance height, location accuracy, compact structure.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
