Preferably, insert in the hole described in and be provided with the positioning step of restriction connecting tube intubating length.
The utility model adopts rapid pipe joint to connect indoor set connecting tube and outdoor unit connecting tube, in rapid pipe joint, uses the sealing between Sealing formation patchhole and connecting tube, avoids refrigrant leakage; Use elastic clip to be fixed in joint body by connecting tube clamping, ensure the reliability that connecting tube connects; And, be provided with Ka Gai to limit elastic clip and connecting tube deviate from from joint body in joint body end, guarantee the reliability of integrated connection, therefore, the installation efficiency that linkage structure of the present utility model not only improves air-conditioning greatly also improves Security during installation.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is general structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of joint body;
The structural representation of Fig. 3 elastic clip;
Fig. 4 is the structural representation of Ka Gai.
Embodiment
As shown in Figure 1, a kind of linkage structure of break valve for air conditioner, comprise joint body 1, Sealing 2, elastic clip 3 and card lid 4, as shown in Figure 2, patchhole 11 is provided with in joint body 1, connecting tube inserts in described patchhole 11, described Sealing 2 is for the formation of the sealing between patchhole 11 and connecting tube, described elastic clip 3 is for being fixed in joint body 1 by connecting tube clamping, and described card lid 4 is fixed on joint body 1 end for limiting elastic clip 3 and connecting tube is deviate from from joint body 1.
Wherein, connecting tube comprises indoor set connecting tube 5 and outdoor unit connecting tube 6, and indoor set connecting tube 5 and outdoor unit connecting tube 6 all adopt copper pipe, and indoor set copper pipe and outdoor unit copper pipe insert described patchhole 11 from joint body 1 two ends.The positioning step of restriction connecting tube intubating length is provided with in described patchhole 11.During installation, only copper pipe need be inserted joint body 1, if do not have positioning step, copper pipe can be inserted into the end, and when there being positioning step, copper pipe is inserted into positioning step place.
Described Sealing 2 is for being located at least one the O type circle between patchhole 11 and connecting tube.Be preferably 2,2 O type circles and copper pipe carry out interference fit, play dual sealing functions.As shown in Figure 2, be provided with sealing draw-in groove 13, O type circle at patchhole 11 inwall to be arranged in sealing draw-in groove 13.
Described elastic clip 3 is metal ring, is interference fit between described metal ring and patchhole 11 and connecting tube.Elastic clip 3 and copper pipe carry out interference fit, for blocking copper pipe cylindrical, guarantee that copper pipe can not fly out under a certain pressure, and elastic clip 3 and patchhole 11 carry out interference fit, guarantee that elastic clip 3 itself is fixed in joint body 1.
And the interference fit in order to realize and between patchhole 11 and connecting tube, as shown in Figure 3, inner ring 31 and the outer ring 32 of described metal ring are equipped with in conjunction with tooth.In conjunction with tooth in roughly isosceles trapezoidal structure, adjacent is provided with interval trough in conjunction with between tooth, can be out of shape when being squeezed in conjunction with tooth on the inner ring 31 of metal ring and outer ring 32, and forms interference fit between patchhole 11 and connecting tube.
As shown in Figure 4, described card lid 4 is made up of lid portion 41 and intercalation part 42, and the diameter in lid portion 41 is greater than the ledge structure that intercalation part 42 diameter forms card lid cylindrical.As shown in Figure 2, described patchhole 11 is provided with insert port 12 in the end of joint body 1, and insert port 12 internal diameter is greater than patchhole 11 inside diameter, and wherein elastic clip 3 is positioned at insert port 12 the inner.
Described intercalation part 42 to insert in described insert port 12 and and interference fit between insert port 12.Further, be provided with limiting card mouth structure between described insert port 12 and intercalation part 42, as shown in Figure 2, this limiting card mouth structure comprises the spacing draw-in groove 14 that insert port 12 inwall is arranged, and described intercalation part 42 is provided with the limited location snap ring 43 coordinated with spacing draw-in groove 14.Because intercalation part 42 and insert port 12 carry out interference fit, be provided with spacing bayonet socket simultaneously, it is hereby ensured that elastic clip 3 and copper pipe can not fly out.
The head end of described intercalation part 42 is provided with chamfering 44, and chamfering the inner extends to limited location snap ring 43 place, therefore limited location snap ring cross section roughly at right angles triangular structure.If use certain moment inwardly to press card lid 4 on earth, chamfering 44 acts on the inner ring 31 of elastic clip, the inner ring 31 of shell fragment intermediate plate 3 is out of shape, also makes to occur gap between elastic clip inner ring 31 and connecting tube, is convenient to take out copper pipe.
