Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment discloses a high-safety pneumatic connector, as shown in fig. 1-4, which comprises a pipe body 1 and insertion ports 2 arranged at two ends of the pipe body 1, wherein an elastic pressing ring 3 and a sealing sleeve 4 are sequentially arranged in the insertion port 2, the elastic pressing ring 3 is abutted against the sealing sleeve 4, the sealing sleeve 4 can stretch and slide in the insertion port 2, a plurality of anti-retreat sheets are arranged on the elastic pressing ring 3, the anti-retreat sheets incline towards the inside of the pipe body 1, so that the anti-retreat sheets do not play a limiting role when an air pipe is inserted from the insertion port 2, when the air pipe is pulled outwards, the anti-retreat sheets can tightly clamp the air pipe to prevent the air pipe from being pulled out, at the moment, the elastic pressing ring 3 is pushed to expand only by pressing the sealing sleeve 4 inwards, the anti-retreat sheets are also stretched outwards to enable the air pipe to move smoothly, when the sealing sleeve 4 is loosened, the elastic pressing ring 3 contracts and resets, the anti-withdrawing sheet on the sealing sleeve is also reset, and the sealing sleeve 4 is also ejected out by the elastic pressing ring 3 and returns to the initial position; referring to fig. 2, a protrusion 5 protruding to a side surface is provided on an outer end surface of the seal sleeve 4, and the protrusion 5 is provided on both sides of the seal sleeve 4, so that the area of a pressing portion is larger, the space for operation is also larger, and it is convenient for an operator to press on both sides.

Further, a pressure relief hole 6 is formed in pipe body 1, a sealing assembly 7 for sealing pressure relief hole 6 is arranged at pressure relief hole 6, sealing assembly 7 includes a sealing bead 701, a spring 702 and a snap ring 703, snap ring 703 is fixed at pressure relief hole 6 through an barb, a shoulder 601 is arranged in pressure relief hole 6, spring 702 and sealing bead 701 are arranged between shoulder 601 and snap ring 703, one end of spring 702 abuts against shoulder 601, and the other end abuts against sealing bead 701, when in normal use, spring 702 pushes sealing bead 701 outwards, the surface of sealing bead 701 abuts against snap ring 703, sealing is realized, and when pipe body 1 conducts gas normally, part of gas also pushes sealing bead 701 outwards through pressure relief hole 6, that is, the higher the gas pressure in pipe body 1 is, the better the sealing effect is; an ejector rod 8 penetrates through the pipe body 1, one end of the ejector rod 8 abuts against the sealing sleeve 4, the other end of the ejector rod 8 extends to the sealing assembly 7, when an operator is ready to disassemble the air pipe and the joint, the sealing sleeve 4 is pressed down to drive the ejector rod 8 abutting against the sealing sleeve 4 to move, please refer to fig. 3, at this time, a conical structure arranged at one end, close to the sealing assembly 7, of the ejector rod 8 is pushed outwards, the sealing ball 701 is pressed downwards through a conical inclined surface, so that sealing between the sealing ball 701 and the clamping ring 703 is damaged, air in the pipe body 1 is sprayed outwards through the pressure release hole 6, the sprayed air is blocked by a protective sleeve 10 in threaded connection with the pipe body 1 and is diffused to one side, the spraying speed and the impact force of the air are greatly reduced, the use is safer, and the elastic pressing ring 3 expands along with continuous pressing of the sealing sleeve 4, so that the air pipe can be smoothly pulled out from the interface 2; the utility model discloses when pressing down seal cover pipe 4, open pressure release hole 6 earlier and carry out the pressure release, the elastic snap ring 3 deflection at this moment is not enough, the trachea can not be extracted, along with seal cover pipe 4 gradually according to when to the end, elastic snap ring 3 just warp completely, remove with tracheal fixed, and a large amount of gases in body 1 have been followed pressure release hole 6 and discharged this moment, and gas is no longer spout from the gap between trachea and interface 2, has protected operating personnel's safety in utilization.

Further, the end that ejector pin 8 and seal bushing 4 offset is provided with big terminal surface 11, and the butt has reset spring 12 between big terminal surface 11 and the body 1, resets ejector pin 8 through reset spring 12 for when operating personnel loosened seal bushing 4, seal bushing 4 is when being reset by elastic compression ring 3, ejector pin 8 also can reset, and seal bead 601 is also by spring 602 jack-up again, resumes sealed state.

The utility model discloses it is convenient to use, and the security is good, especially is fit for frequently pulling out and inserts tracheal production line in needs, has effectively protected operating personnel when pulling out and inserting the trachea safety.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
