[0011] Beneficial Effects
[0012] In the prior art, the inert gas interface of the aerosol generator is usually used to connect the catheter to deliver the inert gas to the generator. When connected, the interface and the catheter connecting end are fixed by a ring clamp. However, the existing connection clamp is usually fixed with bolts, which is inconvenient to disassemble and assemble, and takes a long time, which reduces the connection speed between the interface and the catheter, thereby reducing production efficiency. To address this problem, the utility model adopts a quick connection clamp, inserts the catheter connector into the interface, and then nests the connection clamp outside its connection. Finally, the plug at the bottom end of the first clamping ring is inserted into the slot at the bottom end of the second clamping ring. After entering the slot, the end of the plug squeezes the card, and when the card moves to the tail end of the plug, the card is popped out and connected to the end of the plug under the action of the clamping spring. The end faces of the tail end are engaged with each other, so that the first clamping ring and the second clamping ring are fixed. If the plug is moved to the left again, the front end face of the limit ring squeezes the clamping piece. When the clamping piece moves to the rear end face of the limit ring, under the action of the engaging spring, the clamping piece pops out and engages with the rear end face of the limit ring. Since the rear end face is set as an inclined plane, the clamping piece pulls the limit ring to the left until it is in fit with the end face of the tail end of the plug. Then the clamping piece disengages from the limit ring, thereby disengaging the slot from the plug. Under the action of the reset spring, the limit ring returns to its original position, thereby separating the first clamping ring and the second clamping ring, completing quick disassembly and assembly. It only needs to be plugged in and out, without the use of other tools. The operation is simple, time-saving and labor-saving, and the connection speed between the interface and the catheter is improved, thereby improving production efficiency.

The stainless steel connecting clamp 3 has good corrosion resistance and cleaning properties, and has a long service life, reducing the replacement frequency and maintenance costs. A silicone sleeve is bonded to the inner wall of the connecting clamp 3, and the silicone sleeve plays a sealing role to prevent the inert gas from overflowing, while increasing the friction between the clamp and the interface, improving the connection stability of the clamp, and the silicone sleeve has excellent chemical resistance, can resist the erosion of various corrosive media such as acids, alkalis, solvents, etc., and has better durability.
[0023] The connecting clamp 3 is composed of a first clamping ring 301 and a second clamping ring 302, and the top of the first clamping ring 301 is rotatably connected to the top of the second clamping ring 302. A plug 4 is fixed to the side of the bottom end of the first clamping ring 301, and the plug 4 is umbrella-shaped. The end of the plug 4 is hemispherical, and the inner diameter of the slot 7 is equal to the spherical radius of the end of the plug 4. The hemispherical plug 4 is easy to insert into the slot 7, reducing the friction between the plug 4 and the inner wall of the slot 7, and at the same time it is easy to squeeze the card 8 into the movable groove 11. A limiting ring 5 is nested on the surface of the plug 4, and the end faces on both sides of the limiting ring 5 are set as inclined planes, which further facilitates the clamp 8 to slide over the end face of the limiting ring 5, making the clamp connection faster. A reset spring 6 is provided between the limiting ring 5 and the side of the first clamping ring 301, and the reset spring 6 is nested in the surface of the plug 4. A slot 7 is provided on the side of the bottom end of the second clamping ring 302, and a movable groove 11 is provided on the inner wall of the slot 7. A clamp 8 is provided inside the movable groove 11, and the top of the clamp 8 is set as an inclined surface, so that the clamp can slide over the end of the plug 4 and also clamp the end face of the end of the plug 4. A movable rod 9 is fixed to the bottom of the clamp 8, and the movable rod 9 is slidably connected to the bottom surface of the movable groove 11. The bottom end of the movable rod 9 is set as a limiting block 10, and a locking spring 12 is nested on the surface of the movable rod 9.
[0024] In the prior art, the inert gas interface of the aerosol generator is usually used to connect the catheter to deliver the inert gas to the generator. When connected, the interface and the catheter connecting end are fixed by a ring clamp. However, the existing connection clamp is usually fixed with bolts, which is inconvenient to disassemble and assemble, and takes a long time, which reduces the connection speed between the interface and the catheter, thereby reducing production efficiency. To address this problem, the utility model adopts a quick connection clamp, inserts the catheter connector into the interface, and then nests the connection clamp 3 outside its connection, and finally inserts the plug 4 at the bottom end of the first clamping ring 301 into the slot 7 at the bottom end of the second clamping ring 302. After entering the slot 7, the end of the plug 4 squeezes the clamp 8. When the clamp 8 moves to the tail end of the plug 4, under the action of the locking spring 12, the clamp 8 pops out and locks with the end face of the tail end of the plug 4. When the plug 4 is moved to the left again, the front end face of the limiting ring 5 squeezes the clamping piece 8. When the clamping piece 8 moves to the rear end face of the limiting ring 5, the clamping piece 8 is popped out and clamped with the rear end face of the limiting ring 5 under the action of the clamping spring 12. Since the rear end face is set as an inclined plane, the clamping piece 8 pulls the limiting ring 5 to the left until it fits with the end face of the end of the plug 4. Then, the clamping piece 8 disengages from the limiting ring 5, thereby disengaging the slot 7 from the plug 4. Under the action of the reset spring 6, the limiting ring 5 returns to its original position, thereby separating the first clamping ring 301 and the second clamping ring 302, completing quick disassembly and assembly. It only needs to be plugged in and out, and no other tools are needed. The operation is simple, time-saving and labor-saving, and the connection speed between the interface and the catheter is improved, thereby improving production efficiency.
[0025] The working principle of the utility model is as follows: insert the catheter connector into the interface, then embed the connecting clamp 3 outside its connection, and finally insert the plug 4 at the bottom end of the first clamping ring 301 into the slot 7 at the bottom end of the second clamping ring 302. After entering the slot 7, the end of the plug 4 squeezes the clamp 8. When the clamp 8 moves to the tail end of the plug 4, under the action of the clamping spring 12, the clamp 8 pops out and engages with the end face of the tail end of the plug 4, so that the first clamping ring 301 is fixed with the second clamping ring 302. If the plug 4 is moved to the left again, the limit The front end face of the positioning ring 5 squeezes the clamping member 8. When the clamping member 8 moves to the rear end face of the positioning ring 5, under the action of the locking spring 12, the clamping member 8 pops out and locks with the rear end face of the positioning ring 5. Since the rear end face is set as an inclined plane, the clamping member 8 pulls the positioning ring 5 to the left until it is in contact with the end face of the head and tail end of the plug 4. Then the clamping member 8 disengages from the positioning ring 5, thereby disengaging the slot 7 from the plug 4. Under the action of the reset spring 6, the positioning ring 5 returns to its original position, thereby separating the first clamping ring 301 and the second clamping ring 302.
