Detailed Description
Fig. 1 to 4 show a specific embodiment of an air vent connector for rapidly clamping a threaded air tap, which is characterized by comprising a multi-stage step cylindrical connector body 1, wherein an air passage is arranged in the connector body 1, one end of the connector body 1 is provided with an external thread connected with a guide sleeve 6, the other end of the connector body 1 is connected with an air source, the rear end of the guide sleeve 6 is provided with an internal thread hole 62 connected with the connector body 1, the outer side of the guide sleeve 6 is provided with an elastic clamping jaw 4, the front end of the elastic clamping jaw 4 is outwards opened and bent to form a clamping jaw arm 42, the front end of the clamping jaw arm 42 is provided with clamping jaw teeth 41 which are matched with the threaded air tap in a clamping mode, the clamping jaw teeth are identical to the connected air tap in thread specification, a sliding sleeve 2 capable of sliding forwards and backwards along the axis of the connector body 1 is sleeved on the connector body 1, the front end of the sliding sleeve 2 is provided with a step inner hole, the front end of the sliding sleeve 2 is larger than the outer diameter of the sliding sleeve 4, the front end of the sliding sleeve is freely opened to form an inner diameter which is larger than the size of the elastic clamping jaw 4, the front end of the sliding sleeve is smaller than the inner diameter of the sliding sleeve is also smaller than the step end of the sliding sleeve 2, and the outer diameter of the clamping jaw is smaller than the front end of the sliding sleeve is formed and the inner diameter of the sliding sleeve is smaller than the inner diameter of the sliding sleeve 2. The sliding sleeve 2 is sleeved on the cylinder of the connector body 1, and the sliding sleeve 2 is limited in the front-back direction when sliding forwards and backwards along the axial direction of the connector body 1.
Further, the jaw teeth 41 are formed into a plurality of female screw threads having the same specification as the male screw threads of the screw tap to be clamped. Therefore, the connecting rigidity is higher, the axial deformation is small, the sealing performance is improved, in addition, the connected screw thread can be shorter, and even if the screw thread is clamped at the incomplete screw thread tooth position at the front end of the screw thread, the screw thread can be firmly clamped, so that the screw thread can still be normally clamped and used in a space tension environment.
Further, the front end of the guide sleeve 6 is provided with a groove 61 for guiding and limiting the radial movement of the clamping jaw teeth 41, avoiding deflection and realizing accurate engagement between the clamping jaw teeth 41 and the clamped screw threads; the jaw arm 42 is radially movably disposed in a recess 61 in the front end of the guide sleeve 6.
Further, a sealing gasket 5 is provided on the front end surface of the connector body 1 to form a sealing connection with the guide sleeve 6. Thus, an airtight connection is formed between the joint body 1 and the guide sleeve 6.
Further, the elastic clamping jaw 4 is formed by extending a partial outer edge of a bottom ring 43 along an axial direction, and the extending end of the elastic clamping jaw 4 forms a front end.
Further, at least 2 clamping jaw arms are uniformly distributed on the bottom ring 43 by the clamping jaws 4, and the uniformly arranged elastic clamping jaws 4 enable the connected threads to be uniformly stressed, so that air leakage caused by radial movement cannot occur.
Further, the holding jaw 4 is made of a material having elasticity such as spring steel or other materials.
Further, a through groove for accommodating the elastic clamping jaw 4 is formed in the side face of the guide sleeve 6.
Furthermore, the air passage of the connector body 1 is internally provided with a closed standard valve core or a normally open ventilation thimble with only a mandril.
Further, an inner hole at the other end of the connector body 1 is provided with an inner thread connected with an air source connector.
In one embodiment, the other end may also be designed in different interface forms depending on the different forms of the connected joint.
Figures 5 and 6 illustrate the use of a quick-clamp threaded air cap venting adapter of the present invention. When the sliding sleeve 2 slides forwards, the two clamping jaw arms 42 are pressed by the sliding sleeve 2 and elastically deform, so that the two clamping jaw teeth 41 are driven to move radially simultaneously, and clamp the threads of the connected threaded air tap. When the sliding sleeve 2 slides backwards, the clamping jaw arm 42 returns to the original shape and drives the clamping jaw teeth 41 to be separated from the threads of the clamped threaded air faucet.
The foregoing description is only illustrative of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention, i.e., the equivalent changes and modifications to the invention as described in the claims and specification should be considered as falling within the scope of the invention.
