Embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the utility model.
To shown in Figure 5, the tamper discharge pipe connections of present embodiment comprises: pipe joint body 10, stop member, auxiliary nut 20 and elastic component 40 like Fig. 1.Wherein, first end of pipe joint body 10 is a threaded ends 11, and the middle part of pipe joint body 10 has the step end face towards second end of pipe joint body 10, and this step end face is provided with first chisel teeth 12 that along the circumferential direction extends; Stop member is connected second end of pipe joint body 10; Auxiliary nut 20 has the endoporus 21 of second end that wears pipe joint body 10, and first end face of auxiliary nut 20 is provided with second chisel teeth 22 that cooperates and be used for 10 rotations of driving tube joint body with first chisel teeth 12; First end of elastic component 40 is replaced on second end face of auxiliary nut 20, and second end of elastic component 40 is subject to stop member.
As depicted in figs. 1 and 2; Auxiliary nut 20 is set in second end of pipe joint body 10, when when auxiliary nut 20 applies clockwise moment, through the cooperation of first chisel teeth 12 and second chisel teeth 22; Independently pipe joint body 10 can rotate with 20 two parts of auxiliary nut synchronously; Can guarantee pipe joint body 10 and union nut 50 through being threaded, it is as shown in Figure 6 to accomplish assembling condition, thereby connects 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 the union nut 50, plays the effect of anti-dismounting.The elastic force that elastic component 40 produces can make first chisel teeth 12 of pipe joint body 10 and second chisel teeth, 22 better fit of auxiliary nut 20; Simultaneously; Can also prevent that auxiliary nut 20 from coming off when loosening and produce abnormal sound, auxiliary nut 20 can dally under the effect of elastic component 40 and can not break away from pipe joint body 10.
Present embodiment can realize really that the adapter of anti-dismounting connects, and improves the secondary refrigerant leakage problem that causes after existing pipe joint and union nut are disassembled between connecting, make be connected between pipe joint and the union nut tightr; And reduce I&M cost after sale, enlarge the using scope of combustible refrigerant; Be prone to installation, simple in structure, easy to process.
Preferably, elastic component 40 is a spring.As shown in Figure 4, for better fixing first end of elastic component 40, have first groove 23 of first end that is used to hold elastic component 40 on second end face of auxiliary nut 20.As shown in Figure 2, second end of pipe joint body 10 has limited ring groove 13, and stop member is the Sealing shield ring 30 that is removably disposed in the limited ring groove 13, and Sealing shield ring 30 has breach 31.Second end of elastic component 40 is spacing through Sealing shield ring 30.
As depicted in figs. 1 and 2, in the present embodiment, the endoporus 21 of auxiliary nut 20 is a unthreaded hole, has the cylindrical outer surface that cooperates with unthreaded hole between second end to the step end face of pipe joint body 10.
Like Fig. 2, Fig. 3 and shown in Figure 6; The middle part of pipe joint body 10 has annular flange flange 14; The periphery of annular flange flange 14 does not have screw thread; Annular flange flange 14 has second groove towards the end face of second end of pipe joint body 10, and the bottom land of second groove forms step end face, and first chisel teeth 12 is less than or equal to the groove depth of second groove along pipe joint body 10 axial maximum heights.After union nut 50 and pipe joint body 10 are locked, because first chisel teeth 12 of pipe joint body 10 is arranged in second groove and maximum height is less than or equal to groove depth, like this, make that pipe joint body 10 whole stress surfaces are cylindrical, can't be stressed.Avoided when chisel teeth exposes, making it that stress surface arranged is the problem of sphenoid surface, that is, said structure has overcome when chisel teeth exposes also can unclamp possible problem between the union nut 50 and pipe joint body 10, has really played the function of anti-dismounting.
As shown in Figure 3, first chisel teeth 12 has the first driving face 12a that radially extends, and second chisel teeth 22 has the second driving face 22a that radially extends.Said structure power transmission best results.Preferably, all along circumferentially distributing, the quantity of first chisel teeth 12 and second chisel teeth 22 is identical and be at least two for first chisel teeth 12 and second chisel teeth 22.
First end of pipe joint body 10 and cooperating of refrigerant pipe for ease, first end of pipe joint body 10 extend to form the conical surface shape structure outwardly gradually with shrinking.
The utility model also provides a kind of tamper discharge pipe connections assembly; Like Fig. 1, Fig. 2 and shown in Figure 6; Embodiment according to the tamper discharge pipe connections assembly of the utility model comprises union nut 50 and the pipe joint that is connected with union nut 50, and pipe joint is above-mentioned tamper discharge pipe connections.The tamper discharge pipe connections component safety property of the utility model is high, installation is simple.
The utility model also provides a kind of air conditioner, comprises heat exchanger and the connecting tube that is connected with heat exchanger according to the embodiment of the air conditioner of the utility model, and heat exchanger is connected through above-mentioned tamper discharge pipe connections assembly with connecting tube.The air conditioner of the utility model can be realized anti-dismounting linkage structure, has prevented coolant leakage effectively.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
