Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Shown in Fig. 1, the air conditioner temperature-sensitive head stationary installation 1 that the utility model preferred embodiment provides comprises a pair of circular arc clamping part, this pair circular arc clamping part forms an opening (figure is mark not) makes the refrigerant pipe to pass in and out, two circular arc clamping parts comprise orthodrome clamping part 10 and roundlet arc clamping part 11, the place circle of orthodrome clamping part 10 and roundlet arc clamping part 11 intersects, arc transition is adopted in the intersection, and forms reciprocal flange 12 at opening part respectively.
In conjunction with reference to shown in Fig. 2, when air conditioner temperature-sensitive head stationary installation 1 that the utility model provides is installed on the refrigerant pipe 3, orthodrome clamping part 10 clamps refrigerant pipe 3, roundlet arc clamping part 11 clamping temperature-sensitive heads 2 and make temperature-sensitive head 2 simultaneously near refrigerant pipe 3 (, air conditioner temperature-sensitive head stationary installation 1 having been done transparent processing) in order to make the clearer reflection the present invention of accompanying drawing.As shown in Figure 3, Fig. 3 is the mechanical analysis synoptic diagram under the utility model preferred embodiment in working order, the radius of its mid point m, f, g, the formed roundlet arc of n clamping part 11 is decided (preferred design becomes certain interference fit) according to the radius size of temperature-sensitive head 2, the radius of some i, j, the formed orthodrome clamping part 10 of k then with the radius of refrigerant pipe 3 be consistent (preferred design becomes certain interference fit), two circle intersections so just form the stress surface of a strong fixedly refrigerant pipe 3 by circular arc in transition.Because the singularity of design size and the bounce of material, place two circles of two circular arcs intersect at a h place, cause curved surface fg, curved surface kj to have respectively and be subjected to outside elasticity tension, according to mechanics principle, this tension force produces two extruding forces to temperature-sensitive head 2 respectively with h place, 3 liang of round point of contacts of refrigerant pipe, this extruding force has the effect of self-locking, temperature-sensitive head 2 is grabbed firmly be buckled on the refrigerant pipe 3.Extruding force is big more, and card is tight more between temperature-sensitive head 2 and the refrigerant pipe 3, and the temperature that temperature-sensitive head 2 detects is accurate more.
For more clearly illustrate the utility model than with the advantage of prior art, provided the force analysis figure of the temperature-sensitive head stationary installation that general prior art provides among Fig. 4, by the force analysis in the comparison diagram 3 as can be known: because the arm of force L1 (referring to Fig. 4) of ac is much larger than the arm of force L2 (referring to Fig. 3) of eg, node c with respect to same position, g, make stressed curved surface bc, fg deforms, according to mechanics principle, directed force F 1 among Fig. 3 need be much larger than the directed force F among Fig. 42, promptly, the fixed sturcture that adopts the utility model to provide, need bigger external force just can deform, therefore the possibility that comes off is less than prior art, and temperature-sensitive head 2 can better be fixed on the refrigerant pipe 3.
Simultaneously, because in the present embodiment, the opening direction of the opening ek of two circular arc clamping parts (as the inlet of refrigerant pipe 3) is vertical mutually with the opening direction of the opening mn (as the inlet of temperature-sensitive head 2) of roundlet arc clamping part 11, this makes the force direction that is subjected to of temperature-sensitive head 2 go out Inbound (being the opening direction of orthodrome clamping part 10) perpendicular to refrigerant pipe 3, therefore the extruding force between temperature-sensitive head 2 and the refrigerant pipe 3 is difficult to cause refrigerant pipe 3 to deviate from from opening mn, and the two extruding force obviously can be aggravated coming off of refrigerant pipe in the prior art.
In addition, based on consideration easy for installation, the utility model preferred embodiment is carried out the flange processing with its orthodrome clamping part 10 and roundlet arc clamping part 11 at opening part, in order to avoid scratch the refrigerant pipe in installation process.
The above only is preferred embodiment of the present utility model, not in order to restriction the utility model.For example, the opening direction of the opening ek of two circular arc clamping parts not necessarily wants strict vertical with the opening direction of the opening mn of roundlet arc clamping part 11, the two has certain angle (promptly also not parallel in one direction) to get final product, and, though the e point is on the circle at orthodrome place in the foregoing description, in fact can more close k point according to actual conditions e point, perhaps more close m point, promptly the e point among the opening ek does not need on the strict circle that is arranged on the orthodrome place.Moreover, also can change as the orthodrome clamping part 10 of the first circular arc clamping part with as the magnitude relationship between the roundlet arc clamping part 11 of the second circular arc clamping part according to actual conditions, the caliber of refrigerant pipe 2 is less if temperature-sensitive head 2 is big, and then the radius of the second circular arc clamping part can be greater than the radius of the first circular arc clamping part.All any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
