Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-3, a gas core with high protection strength, including the casing 1, the middle part fixed connection stopper 4 in the casing 1, the lower extreme fixed connection spring 2 in the casing 1, the sealed piece 3 of 2 upper ends fixed connection of spring, the sealed piece 3 upper end is laminated with stopper 4, the threaded connection helmet 8 on the casing 1, mounting groove 81 has been seted up at the middle part of helmet 8, install sealing mechanism 5 in the mounting groove 81, not only can seal protection through helmet 8 to casing 1, still can be through the sealing mechanism 5 that sets up at helmet 8, make the combination of sealing mechanism 5 and stopper 4, form inside sealed, make the sealed effect of gas core better, improve inside protection, prevent gas leakage.

Present valve core protective strength is high inadequately, and when using, the 2 structures of spring that 3 lower extremes of sealed piece in the valve core are connected, and under long-time the using, elasticity can reduce, leads to sealed piece 3 can't closely laminate with stopper 4, and sealing mechanism 5 includes boss 56, and boss 56 and stopper 4 upper end are to the laminating, boss 56 upper end middle part fixed connection regulating tube 55, regulating tube 55 upper end threaded connection threaded rod 51.

Through using threaded rod 51 to drive control tube 55 and remove, make control tube 55 can drive boss 56 and stopper 4 and laminate mutually to strengthen inside sealed effect, not only the sealed piece 3 of bottom seals the gas core, can also strengthen sealedly to the gas core at the boss 56 and the stopper 4 combination that the upper end set up, make sealed effect better, improve inside proof strength.

Specifically, in order to use threaded rod 51 to drive adjusting tube 55 and remove the use, at threaded rod 51 upper end sliding connection pull rod 52 to pull 53 at pull rod 52 upper end fixed connection, pull 53 and mounting groove 81 looks adaptation, make to rotate and pull 53 and can drive threaded rod 51 and rotate, and will pull 53 to set up to be the shape with mounting groove 81 looks adaptation, can be convenient for pull 53's storage.

By pulling the pull handle 53, the pull handle 53 drives the pull rod 52 to move, the pull rod 52 is far away from the threaded rod 51, meanwhile, the elastic part 54 extends, then the pull handle 53 is rotated, the pull handle 53 drives the pull rod 52 to rotate, the threaded rod 51 driven by the pull rod 52 rotates, the threaded rod 51 drives the adjusting pipe 55 to move, the adjusting pipe 55 drives the reinforcing block 56 to approach the limiting block 4, and the reinforcing block 56 is attached to the limiting block 4.

The threaded rod 51 is internally provided with a sliding groove, the inner bottom end of the sliding groove is fixedly connected with an elastic piece 54, and the elastic piece 54 is fixedly connected with the bottom end of the pull rod 52, so that the pull rod 52 can be conveniently driven to move for use.

Specifically, in order to avoid threaded rod 51 to drive adjusting tube 55 to rotate when rotating for adjusting tube 55 can't drive boss 56 and descend, at the equal fixed connection mounting panel 6 in adjusting tube 55 both sides, mounting panel 6 upper end fixed connection telescopic link 7, telescopic link 7 upper end and 8 inner wall fixed connection of helmet.

When the threaded rod 51 rotates, the adjusting pipe 55 can be driven by the threaded rod 51 to move due to the telescopic rods 7 arranged on the two sides of the adjusting pipe 55 and the connection between the telescopic rods 7 and the protective cap 8.

Specifically, threaded rod 51 and mounting groove 81 rotate to be connected, and the mounting groove 81 upper end is equipped with the sealing ring, plays sealed effect, makes things convenient for threaded rod 51 to use in mounting groove 81 to drive the regulation of regulating tube 55 and use.

When the utility model is used, the protective cap 8 can be rotated to connect the protective cap 8 with the shell 1 by screw thread, then the pull handle 53 is pulled to make the pull handle 53 drive the pull rod 52 to move and make the pull rod 52 keep away from the threaded rod 51, simultaneously the elastic piece 54 extends, then the pull handle 53 is rotated to make the pull handle 53 drive the pull rod 52 to rotate, the drive threaded rod 51 of the pull rod 52 rotates, because the telescopic rods 7 are arranged at the two sides of the adjusting tube 55 and the telescopic rods 7 are connected with the protective cap 8, the threaded rod 51 can drive the adjusting tube 55 to move, make the regulating tube 55 drive boss 56 and be close to stopper 4 to make boss 56 and stopper 4 laminate mutually, thereby strengthen the sealed to the gas core, prevent gas leakage, avoid being not enough because of the elasticity of spring 2, the gas leakage phenomenon that sealed piece 3 that leads to and stopper 4 are not enough to laminate appears, the laminating back can send out and draw handle 53, make elastic component 54 recover, and draw pull rod 52 and draw handle 53 to recover, make draw handle 53 get into in the mounting groove 81.
