Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to air conditioner joint technical field especially relates to a quick joint. BACKGROUND
[0002] The existing air conditioner installs, and indoor unit leads out through copper pipe, and needs special technical personnel to complete in the process of connecting and debugging with outdoor unit, and there is complex operation, poor connection stability, and the like, and the copper pipe residual freon pollutes air in the process of dismounting and maintaining, and the environmental protection performance is poor, and the outdoor high altitude installation is dangerous, and the installation cost is high, and the like, especially the air conditioner exported to the developed countries of Europe and America, the traditional installation cost is higher than the whole set air conditioner equipment cost, and along with the domestic labor cost improvement and the long-term consideration of safety and environment, it is very necessary to provide a new coupling device of quick installation to ensure the performance requirement of air conditioner in different states such as factory delivery, installation work and machine moving, and the operation is convenient, safe and reliable.
[0003] Based on the above reasons, the present design provides a quick joint. SUMMARY
[0004] The utility model discloses a quick joint.
[0005] In order to achieve the above object, the utility model is through such technical scheme to realize, a quick joint, including male joint and female joint, the female joint includes male cylinder, the left end of male cylinder is provided with first dustproof cap, the side part of first dustproof cap is provided with nut shape encloses, the rear part of nut shape encloses is provided with step, the rear end of step is provided with first abutting spring, the number of turns of first abutting spring is 3.5 turns to 5 turns, and the both ends end face of first abutting spring is ground into plane, the rigidity of first abutting spring is 18N to 22N, the rear end of first abutting spring is also provided with butt joint female head, the first O ring is arranged in butt joint female head, butt joint female head is connected with male joint thread, the left end of male joint is provided with butt joint male head, the second O ring is arranged in butt joint male head, and the first O ring is less than second O ring.
[0006] Preferably, the rear end of the butt joint male head is further provided with a second abutting spring having a number of turns of 3.5 turns to 5 turns, and both end faces of the second abutting spring are ground into a plane. The rigidity of the second abutting spring is 18N to 22N. A second dustproof cap is arranged at the right end of the second abutting spring.
[0007] The above-mentioned scheme has the beneficial effects that:
[0008] This quick connector, through its threaded connection and the interaction between the first and second clamping springs on the corresponding male and female connectors, as well as the corresponding first and second O-rings, not only makes the quick connector easier and faster to connect, but also provides better sealing performance. Furthermore, the diameter difference between the first and second O-rings makes the contact of the sealing rings tighter. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0010] The present invention will be further described clearly and completely below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto. Example
[0011] like Figure 1 As shown, a quick connector includes a male connector 1 and a female connector 2. The female connector 2 includes a male cylindrical body. A first dust cap 3 is provided at the left end of the male cylindrical body. A nut-shaped surround 4 is provided on the side of the first dust cap 3. A step 5 is provided at the rear of the nut-shaped surround 4. A first clamping spring 6 is provided at the rear end of the step 5. The number of turns of the first clamping spring 6 is 3.5 to 5, and the end faces of the first clamping spring 6 are ground into flat surfaces. The stiffness of the first clamping spring 6 is 18N to 22N. A mating female head 7 is also provided at the rear end of the first clamping spring 6. A first O-ring 8 is provided inside the mating female head 7. The mating female head 7 is threadedly connected to the male connector 1. A mating male head 9 is provided at the left end of the male connector 1. A second O-ring 10 is provided inside the mating male head 9. The first O-ring 8 is smaller than the second O-ring 10.
[0012] In this embodiment, the rear end of the male connector 9 is further provided with a second clamping spring 11 with 3.5 to 5 turns, and the two end faces of the second clamping spring 11 are ground into flat surfaces. The stiffness of the second clamping spring 11 is 18N to 22N, and a second dust cap 13 is provided at the right end of the second clamping spring 11.
[0013] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
