Referring to FIG. 1 to FIG. 7 , a push-type British air nozzle inflation joint 100 according to a preferred embodiment of the present invention includes a nozzle joint 10 , an outer joint 20 , and a joint. 30. A trachea 40, a sheath 50, a spring 60 and a soft compression ring 70, wherein:
Referring to the first to third figures, the nozzle base 10 has a screwing portion 11 and a limiting portion 12 coaxially coupled to the screwing portion 11; the free end of the screwing portion 11 extends axially inward. There is a first movable hole 111. The outer peripheral surface of the screwing portion 11 has an external thread 112. One side of the limiting portion 12 extends from the outside to the inner side to define a limiting receptacle 121 and a connecting slot 122. The positional groove 121 communicates with the communication groove 122. The free end of the limiting portion 12 extends axially inwardly with a nozzle opening 123. The nozzle opening 123 communicates with the limiting receptacle 121. The communication slot 122 and the The first movable holes 111 have a restricting opening 124 communicating with each other, and the limiting opening 124 has a smaller diameter than the first movable hole 111.
Referring to the first to third figures, the external pipe 20 has an internal thread 21 at one end, and the internal thread 21 is screwed to the external thread 112 of the nozzle base 10, and the external pipe 20 is axially penetrated. The second movable hole 22 is in communication with the first movable hole 111. The other end of the external pipe 20 extends axially inwardly with a tracheal opening 23 communicating with the second movable hole 22, and the tracheal opening 23 The aperture is smaller than the aperture of the second movable aperture 22.
Referring to the first to third figures, the joint 30 has a joint body 31 and an inflation hole 32 extending axially through the joint body 31. The joint body 31 has a pipe joint 311 and a nozzle joint on the outer circumference. 312 and a limiting portion 313 connected between the pipe joint portion 311 and the nozzle joint portion 312, the outer diameter of the restricting portion 313 is larger than the outer diameter of the pipe joint portion 311 and the nozzle joint portion 312; The nozzle is disposed in the first movable hole 111 and the second movable hole 22 of the external nozzle 20, and is reciprocally displaced by external force, and the pipe joint 311 faces the air tube opening 23, The nozzle joint 312 faces the restriction opening 124.
Referring to the first to third figures, one end of the air tube 40 is inserted from the air tube opening 23 of the outer tube 20 and is sleeved on the tube connecting portion 311 of the joint 30. The other end of the air tube 40 is Connect the pump or air reservoir (not shown).
Referring to the first to third figures, the sleeve 50 is fastened to the tube portion 311 of the air tube 40 and the joint 30 to prevent the air tube 40 from being loosened from the joint 30.
Referring to the first to third figures, the spring 60 abuts between the restricting portion 313 of the joint 30 and the wall surface of the air tube opening 23 of the outer tube to provide the elasticity of the joint 30 to the direction of the restricting opening 124. Pre-forcer.

Therefore, the above is a description of each component of the push-type British air nozzle inflation joint 100 and its assembly manner provided by a preferred embodiment of the present invention, and then its use characteristics are as follows:
When a British air nozzle 91 is to be inflated (as shown in the third figure), the air tube 40 is first pulled to cause the joint 30 to compress the spring 60 and move toward the air tube opening 23 (as shown in the fourth figure). ). Then, the nut 911 of the British air nozzle 91 is placed in the limiting receptacle 121 of the nozzle connector 10, so that the inflation end 912 of the British air nozzle 91 is located in the communication slot 122 ( As shown in the fifth and sixth figures, the air tube 40 is released again, and the joint 30 is pushed by the elastic force of the spring 60 to move toward the restricting opening 124 so that the nozzle joint portion 312 is located at the joint 30. The inner soft compression ring 70 is pressed against the inflation end 912 of the British air nozzle (as shown in FIG. 7), so that the gas in the inflator or the air reservoir can be poured into the air by the air pipe 40. In the air nozzle 91, the effect of inflating the British air nozzle 91 is achieved.
Therefore, since the finite-position slot 121 and the communication slot 122 are formed in the present invention, the English air nozzle 91 can be placed in the nozzle socket 10 by the limiting receptacle 121 and the communication slot 122, and is pushed and pulled by means of pushing and pulling. The present invention is joined to the British air nozzle, so that the operation mode can be made more convenient, and the structure of the present invention is simple, so that the cost can be greatly reduced.
In addition, as shown in the eighth figure, the limit pocket 121 of the present invention can be accommodated by the US and the French joint 92 in addition to the British gas nozzle, so that the present invention can be directly In order to inflate the British air nozzle, the American air nozzle or the French air nozzle can be inflated by the transfer with the US-Freight joint to improve the applicability of the present invention.
The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all of the related art in the art according to the present invention are equivalent to the present invention. The scope of coverage.
