Detailed Description
The structure and principles of such apparatus and method will be apparent to those skilled in the art from the following further description taken in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In this embodiment, through the air feed valve socket to current air respirator carry out structural design, through carrying out the institutional advancement inside air respirator air feed valve socket, design a rotatable button on air respirator air feed valve socket and realize the lever drive jump ring operation to reach convenient and fast labour saving and time saving and pull out on the face guard and insert the air feed valve.
Referring to fig. 1 and 2, in this embodiment, the mask with the rotary button on the air supply valve insertion opening includes an air breathing mask, a rotary button, a clamp spring and an air supply valve, and the air breathing mask includes a breathing valve seat base body, and the insertion opening for connecting the air supply valve is disposed on the breathing valve seat base body.
Referring to fig. 3, fig. 4, fig. 5 and fig. 6, the socket outside be equipped with the installation department, the installation department include first installation department and the second installation department that bilateral symmetry set up, have the clearance between first installation department and the second installation department, first installation department and second installation department on follow the axis direction of socket be equipped with the pivot spread groove respectively, the inner terminal surface in pivot spread groove is the arc form to cooperate with the connection pivot that the swivel button near-end was equipped with, will the connection pivot of swivel button with the pivot spread groove be connected through interference fit, make the swivel button relatively fixed in this position, but when the distal end of swivel button received the effort of pushing down, can for the near-end of swivel button rotate downwards. Preferably, a plurality of convex parts are further arranged on the surface of the rotary button to increase the resistance of a user in use and facilitate the operation with one hand.
The rotation orbit of the distal end of swivel button on be equipped with the jump ring, the downside of swivel button distal end is equipped with promptly in this embodiment the jump ring, just first installation department and second installation department be in the downside of the distal end of swivel button, for one side of the outer wall of socket promptly, be equipped with spacing recess respectively, be equipped with spacing recess, be used for preventing the jump ring to the swivel button direction too much move, with the jump ring restrict between the outer wall of socket and spacing recess. The ring of socket go up the symmetry and be equipped with two flutings, the both ends of jump ring be equipped with the extension section respectively, the extension section extend to the socket inboard through the fluting and then extend to the socket outside in grooved end from the socket inboard again. When the far end of the rotary button is stressed downwards, the clamp springs are simultaneously stressed, and the outer ends of the extension sections of the clamp springs are opened outwards through the slots, so that the air supply valve can be inserted inwards through the interface to realize connection; and the back stops to exert the effort to the distal end of swivel button, and the jump ring receives the effect of elasticity power of itself to revert to the original state, thereby the extension of jump ring is to the inboard shrink tight air supply valve of clamp, has further guaranteed the firm of its connection to the jump ring drives swivel button's distal end upward movement simultaneously when reverting to the normal position, makes swivel button revert to the normal position. Similarly, when the air supply valve needs to be pulled out, the far end of the rotary button needs to be pressed down, and the clamping of the clamping spring on the air supply valve is released.
In a preferred embodiment, the extending section of the clamp spring is sequentially provided with a first bending section, a second bending section and a third bending section, the first bending section is a step shape formed by two times of bending so as to be matched with the limiting groove, the third bending section is bent towards the outer side of the socket and is used for being matched with the tail end of the slot so as to abut against the outer side of the tail end of the slot, the front side of the third bending section is provided with the second bending section, and the second bending section is bent towards the inner side of the socket so as to better clamp the air supply valve.
Examples
During the use, the jump ring is adorned in the fluting on the breather valve seat base member in the air breathing face guard, the rotation axis of rotatory button is installed in the pivot spread groove on the breather valve seat base member in the air breathing face guard, when the air feed valve inserts the interface on the air breathing face guard, the distal end of rotary button is pressed to the forefinger of hand, the air feed valve is held to other fingers, make rotary button push away the jump ring and warp and outwards open the air feed valve simultaneously inwards and push to the end, then loosen the forefinger, the jump ring just falls into the fluting on the air feed valve, the jump ring rebounds to reset this moment and realizes that air breathing face guard and air feed valve. When the air supply valve is to be pulled out, the forefinger of the hand presses the far end of the rotary button, namely the end of the rotary button far away from the connecting rotating shaft, the other fingers hold the air supply valve, and the air supply valve can be pulled out easily by pulling outwards.
Therefore, a rotatable button is designed on the socket of the air supply valve of the air breathing mask to drive the clamp spring through the lever, so that the air supply valve can be conveniently, quickly, time-saving and labor-saving plugged on the mask, and the air supply valve and the mask can be installed and detached through single-hand operation.
