in the figure, 1 is an inner plug body, 2 is an airflow channel, 3 is a self-locking air return preventing cushion, 4 is an outer sleeve body, 5 is an annular inner edge, 6 is an annular screwing part, and 7 is an annular leakage preventing cushion.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, one embodiment of the present invention is an anti-leakage internal self-locking inflation nozzle, which comprises an inner plug body 1, as shown in fig. 2, the inner part of the inner plug body 1 is provided with an airflow channel 2, more importantly, the upper part of the inner plug body 1 is fixed with a self-locking air return prevention cushion 3, the self-locking air return preventing cushion 3 is made of rubber or similar flexible materials, the self-locking air return preventing cushion 3 is required to be arranged above the airflow channel 2, then an outer sleeve 4 is sleeved outside the inner plug body 1, the upper part of the outer sleeve body 4 is in an opening shape and is provided with an annular inner edge 5, and correspondingly, the self-locking air return preventing cushion 3 is arranged below the annular inner edge 5 and is used for enabling the self-locking air return preventing cushion 3 to be in close contact with the lower part of the annular inner edge 5, namely, when the two parts are in close contact, the self-locking sealing function is realized in the charging connector structure. Preferably, in order to simplify the convenience of assembling and disassembling the outer sleeve 4 and the inner plug 1, an external thread may be provided on the inner wall of the outer sleeve 4, an internal thread may be provided on the outer wall of the inner plug 1, and the outer sleeve 4 may be fixed to the outside of the inner plug 1 by a thread. Meanwhile, the inventor refers to the general structure of the inflating nozzle, and the external profiles of any cross sections of the inner plug body 1 and the outer sleeve body 4 are round.

In this embodiment, through installing outer sleeve 4 in the outside of interior cock body 1, utilize the annular inward flange 5 on outer sleeve 4 upper portion and the auto-lock on interior cock body 1 upper portion to prevent back that air cushion 3 forms sealedly, can realize the function of sealed auto-lock on the charging connector, and usable ordinary PVC trinity structure's charging connector reequips at present, need not to twist the charging connector from the outside of aerifing the product alone, and simple to operate, and belong to initiative leak protection in the leak protection function, also far be less than the outside stopper that has auto-lock leak protection structure in the cost.

As shown in fig. 2, in a more preferred embodiment of the present invention for solving the technical problem, in order to prevent the air leakage phenomenon from occurring in the gap between the outer sleeve 4 and the inner plug 1, which affects the tightness of the self-locking of the charging connector, an annular anti-leakage pad may be further installed on the outer wall of the inner plug 1, and the annular anti-leakage pad is in close contact with the inner wall of the outer sleeve 4. Furthermore, in order to facilitate the operation of detaching the inner plug body 1 from the outer sleeve body 4, an annular screwing part 6 can be additionally arranged at the lower part of the inner plug body 1, and the outward extending part of the annular screwing part 6 is larger than the extending part of the cross section of the outer sleeve body 4.

Referring to fig. 1 and 2, the above preferred embodiment of the present invention is in practical use, the inner plug body 1 is installed on the gas outlet of the inflatable product, in normal state, the gas enters the inflation cavity of the inflatable product from the inlet of the gas channel 2 on the inner plug body 1, because the outer sleeve body 4 is sleeved outside the inner plug body 1 through the screw thread, the self-locking air return preventing cushion 3 is in close contact with the lower part of the inner edge of the outer sleeve body 4, and further the gas return in the inflation cavity can be prevented, a sealed self-locking structure is formed, the annular anti-leakage cushion 7 between the inner plug body 1 and the outer sleeve body 4 is also sealed, so that the sealing performance of the self-locking return of the inflation nozzle can be ensured to the maximum, the gas can only flow through the gas channel 2 in the inner plug body 1 in one way, and the use on the inflation nozzle made.
