Abstract
The invention discloses a thread gage dedicated to a refrigeration screw nut, which comprises a handle, wherein a first measuring joint is arranged at one end of the handle, and a second measuring joint is arranged at the other end. The detection efficiency is greatly improved, the damage rate of the screw nut is lowered, and meanwhile the cost is reduced.
Description
Technical field
The present invention relates to a kind of refrigeration nut special screw thread rule.
Background technology
now the inner structure of the copper nut of refrigeration industry is substantially the same both at home and abroad, copper nut is very high to 90.5～92 degree tapering requirement of the inside, especially require higher to right alignment and the circularity of the conical surface, so to the measurement of copper nut inner structure with regard to most important (efficiency and precision will guarantee simultaneously), refrigeration industry to the measurement of copper nut is now: whether qualifiedly first with STRTHD rule, survey screw thread, then being coated with ink paste on the refrigeration joint conical surface screws toward the nut the inside, withdraw, see whether both are concentric, during measuring angle, that nut is cut open, measure the angle (cut position open and meeting is not affected the accuracy of measurement data) of the conical surface with projector, measuring like this a copper nut will take a lot of trouble, and efficiency is low, precision can not be guaranteed, copper nut is also destroyed, have much room for improvement.
Addressing these problems is extremely urgent as from the foregoing!
In view of this, the inventor has done deep research, and by feat of the experience of being engaged in for many years relevant industries and practice, design a kind of refrigeration nut special screw thread rule, can solve deficiency of the prior art, greatly improve detection efficiency, reduce the destructive rate of nut, reduce costs simultaneously, this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of refrigeration nut special screw thread rule, greatly improve detection efficiency, reduce the destructive rate of nut, reduce costs simultaneously.
Refrigeration nut special screw thread rule is characterized in that: comprise handle, at an end of handle, be provided with the first downhole joint, the other end is provided with the second downhole joint.
Further, the length of described the first downhole joint is greater than the length of the second downhole joint.
Further, in the outside of the first downhole joint, form screw thread, form the smooth conical surface on top, the angle of this conical surface is at 90.5 degree.
Further, in the outside of the second downhole joint, form screw thread, form the smooth conical surface on top, the angle of this conical surface is at 92 degree.
Beneficial effect of the present invention: the present invention in actual use, at first the screw thread of surveying copper nut with the first downhole joint whether can be by, the conical surface angle whether greater than 90.5 degree, whether the right alignment of the conical surface is good, whether the circularity of the conical surface is good, if alright, whether so with the angle that the second downhole joint is surveyed the conical surface, spend less than 92, if good, these important indicators of this copper nut are just qualified so.So greatly improve the checkability of copper nut, whether qualifiedly also can better detect copper nut, more can not destroy nut, reduced cost.
As from the foregoing, the present invention improves detection efficiency greatly, reduces the destructive rate of nut, reduces costs simultaneously.
In order further to explain technical scheme of the present invention, the present invention will be described in detail below by specific embodiment.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention relates to a kind of refrigeration nut special screw thread rule, it is characterized in that: comprise handle 1, at an end of handle 1, be provided with the first downhole joint 2, the other end is provided with the second downhole joint 3.
Further arrange, the length of described the first downhole joint 2 is greater than the length of the second downhole joint 3.
Further arrange, in the outside of the first downhole joint 2, form screw thread 4, form the smooth conical surface 5 on top, the angle of this conical surface 5 is at 90.5 degree.
Further arrange, in the outside of the second downhole joint 3, form screw thread 4, form the smooth conical surface 5 on top, the angle of this conical surface 5 is at 92 degree.
More than that the technical scheme that the embodiment of the present invention provides is described in detail, having applied specific case herein sets forth principle and the embodiment of the embodiment of the present invention, the explanation of above embodiment, be only applicable to help to understand the principle of the embodiment of the present invention; Simultaneously,, for one of ordinary skill in the art,, according to the embodiment of the present invention, all can change to some extent on embodiment and range of application, in sum, this description should not be construed as limitation of the present invention.
Claims (4)
