Background technique
Cuprum alloy has and conducts electricity temperature conductivity excellently, and in those early years refrigerator and air conditioner vaporizer and other parts, adopt Cuprum alloy mostly.In recent years in order to save Cuprum alloy resource, evaporator for refrigerator, evaporator using for air and connection pipe for internal-external unit generally adopt copper-aluminium welding pipe to carry out production and processing.The working life of Cu-AL pipe and performance directly affect working life and the performance of refrigerator and air conditioner.The most immediate cause wherein affecting Cu-AL pipe working life and performance is exactly electrochemical corrosion.In order to the generation of Cu-AL pipe electrochemical corrosion phenomenon in the device that avoids evaporating, ensure the stability of vaporizer in refrigerator and air conditioner, foaming process must be carried out to refrigerator and air conditioner.But in foaming processing procedure, need to solve and prevent stabilizer along the excessive problem of evaporator copper aluminum pipe and hard plastic case courage contact position.Traditional method is fixed on insulating jacket the position that evaporator copper aluminum pipe contacts with hard plastic case courage.In use there is following problem in common insulating jacket: 1, and chuck is not easily installed fixing; 2, jackets inner wall is smooth, easily comes off.The invention provides a kind of Kai Bianshi current limliting to rubber collet for this reason.
Summary of the invention
The invention provides a kind of Kai Bianshi current limliting to rubber collet, solve in above-mentioned background technology and ask a question.
For achieving the above object, the invention provides following technological scheme:
A kind of Kai Bianshi current limliting is to rubber collet, it is characterized in that profile is taper, described taper chuck selects rubber to make, chuck color comprises black, silvery white, purplish red, green or purple, tapered clamp has put ring current limliting saddle and manhole, described ring current limliting saddle there is ' V ' shape groove, center line taper chuck along ' V ' shape groove is cut open, immediately one section of screw thread below ring current limliting saddle, for taper chuck is most advanced and sophisticated below screw thread, described manhole has ' U ' shape groove, the degree of depth of ' U ' shape groove is 2mm ± 0.1mm.
Preferably, described ring current limliting saddle thickness is 5mm+0.1mm, and ring current limliting saddle inner ring diameter is 0.5 times of race diameter.
Preferably, described reach accounts for 2/3 of whole taper chuck height, and height of thread is 0.5mm-0.05mm.
Preferably, described manhole diameter is 0.6 times of ring current limliting saddle inner ring diameter, and manhole internal surface has and vertically draws line, draws the line degree of depth to be not more than 0.2mm.
Preferably, described taper chuck tip diameter is identical with ring current limliting saddle inner ring diameter.
Compared with the prior art, beneficial effect of the present invention is as follows:
Current limliting is designed to taper to rubber collet, and on chuck, manhole internal surface has and vertically draws line, can solve jackets inner wall smooth, hold caducous problem; The ring current limliting saddle of taper chuck has ' V ' shape groove, the center line taper chuck along ' V ' shape groove is cut open, and can solve chuck and not easily install fixing problem.In addition, ring current limliting saddle on chuck, can prevent stabilizer from coming off because of gravity.The present invention designs ingenious, easy for installation, good stability, is applicable to preventing the excessive use of stabilizer in refrigerator.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention
As shown in Figure 1: a kind of Kai Bianshi current limliting is to rubber collet, it is characterized in that profile is taper, described taper chuck selects rubber to make, chuck color comprises black, silvery white, purplish red, green or purple, tapered clamp has put ring current limliting saddle 3 and manhole 2, described ring current limliting saddle 3 there is ' V ' shape groove 1, center line taper chuck along ' V ' shape groove 1 is cut open, immediately one section of screw thread 4 below ring current limliting saddle 3, it is taper chuck tip 6 below screw thread 4, described manhole 2 there is ' U ' shape groove 7, the degree of depth of ' U ' shape groove 7 is 2mm ± 0.1mm.Described ring current limliting saddle 3 thickness is 5mm+0.1mm, and ring current limliting saddle 3 inner ring diameter is 0.5 times of race diameter.Described screw thread 4 length accounts for 2/3 of whole taper chuck height, and screw thread 4 degree of depth is 0.5mm-0.05mm.Described manhole 2 diameter is 0.6 times of ring current limliting saddle 3 inner ring diameter, and manhole 2 internal surface has and vertically draws line 5, draws line 5 degree of depth to be not more than 0.2mm.Most advanced and sophisticated 6 diameters of described taper chuck are identical with ring current limliting saddle 3 inner ring diameter.
