Embodiment
It should be noted that, in the situation that do not conflict, embodiment and the feature in embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
As shown in Figures 1 to 5, the Anti-detachable pipe connector of the present embodiment comprises: pipe joint body 10, stop member, auxiliary nut 20 and elastic component 40.Wherein, the first end of pipe joint body 10 is threaded ends 11, and the middle part of pipe joint body 10 has the step end face towards the second end of pipe joint body 10, and this step end face is provided with the first chisel teeth 12 along the circumferential direction extended; Stop member is connected to the second end of pipe joint body 10; Auxiliary nut 20 has the endoporus 21 of the second end that wears pipe joint body 10, and the first end face of auxiliary nut 20 is provided with the second chisel teeth 22 that coordinates with the first chisel teeth 12 and rotate for driving tube joint body 10; The first end of elastic component 40 is supported on the second end face of auxiliary nut 20, and the second end of elastic component 40 is limited to stop member.
As depicted in figs. 1 and 2, auxiliary nut 20 is set in the second end of pipe joint body 10, when when auxiliary nut 20 applies clockwise moment, cooperation by the first chisel teeth 12 and the second chisel teeth 22, independently pipe joint body 10 and 20 two part energy synchronous rotaries of auxiliary nut, can guarantee that pipe joint body 10 and union nut 50 are threaded connection, complete assembling condition as shown in Figure 6, thereby connect vaporizer and connecting tube.But when when auxiliary nut 20 applies anticlockwise moment, auxiliary nut 20 can't apply moment of torsion to pipe joint body 10, has guaranteed closely cooperating between pipe joint body 10 and union nut 50, plays the effect of Anti-dismantling.The elastic force that elastic component 40 produces can make the first chisel teeth 12 of pipe joint body 10 and the second chisel teeth 22 of auxiliary nut 20 better coordinate, simultaneously, can also prevent that auxiliary nut 20 from coming off and producing abnormal sound when loosening, auxiliary nut 20 can dally and can not break away from pipe joint body 10 under the effect of elastic component 40.
The present embodiment can really realize that the adapter of Anti-dismantling connects, and improves after existing pipe joint and union nut are disassembled between connecting the secondary refrigerant leakage problem caused, and makes to be connected between pipe joint and union nut tightr; And reduce I&M cost after sale, enlarge the using scope of combustible refrigerant; Easily installation, simple in structure, easy to process.
Preferably, elastic component 40 is spring.As shown in Figure 4, for the better fixedly first end of elastic component 40, there is the first groove 23 of the first end for holding elastic component 40 on the second end face of auxiliary nut 20.As shown in Figure 2, the second end of pipe joint body 10 has limited ring groove 13, and stop member is the Sealing shield ring 30 be removably disposed in limited ring groove 13, and Sealing shield ring 30 has breach 31.The second end of elastic component 40 is spacing by Sealing shield ring 30.
As depicted in figs. 1 and 2, in the present embodiment, the endoporus 21 of auxiliary nut 20 is unthreaded hole, and the second end of pipe joint body 10 is to having the cylindrical outer surface coordinated with unthreaded hole between step end face.
As shown in Fig. 2, Fig. 3 and Fig. 6, the middle part of pipe joint body 10 has annular flange flange 14, the periphery of annular flange flange 14 is without screw thread, annular flange flange 14 has the second groove towards the end face of the second end of pipe joint body 10, the bottom land of the second groove forms step end face, and along pipe joint body 10, axial maximum height is less than or equal to the groove depth of the second groove to the first chisel teeth 12.After union nut 50 and 10 lockings of pipe joint body, because the first chisel teeth 12 of pipe joint body 10 is arranged in the second groove and maximum height is less than or equal to groove depth, like this, it is cylindrical making the whole stress surface of pipe joint body 10, can't be stressed.Avoided when chisel teeth exposes, making it that stress surface be arranged is the problem of sphenoid surface, that is, said structure has overcome when chisel teeth exposes also can unclamp possible problem between union nut 50 and pipe joint body 10, has really played the function of Anti-dismantling.
As shown in Figure 3, the first chisel teeth 12 has the first driving face 12a radially extended, and the second chisel teeth 22 has the second driving face 22a radially extended.Said structure power transmission best results.Preferably, the first chisel teeth 12 and the second chisel teeth 22 are all along circumferentially distributing, and the quantity of the first chisel teeth 12 and the second chisel teeth 22 is identical and be at least two.
For coordinating of the first end that facilitates pipe joint body 10 and refrigerant pipe, the first end of pipe joint body 10 extends to form the conical surface shape structure outwardly gradually with shrinking.
The present invention also provides a kind of Anti-detachable pipe connector assembly, as shown in Figure 1, Figure 2 with shown in Fig. 6, comprise union nut 50 and the pipe joint be connected with union nut 50 according to the embodiment of Anti-detachable pipe connector assembly of the present invention, pipe joint is above-mentioned Anti-detachable pipe connector.Anti-detachable pipe connector component safety of the present invention is high, installation is simple.
The present invention also provides a kind of air conditioner, according to the embodiment of air conditioner of the present invention, comprises heat exchanger and the connecting tube be connected with heat exchanger, and heat exchanger is connected by above-mentioned Anti-detachable pipe connector assembly with connecting tube.Air conditioner of the present invention can be realized the Anti-dismantling linkage structure, has effectively prevented coolant leakage.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
