Abstract
The utility model relates to a sensor structure of an injection molding fixed rotatable screw. The front end of a sensor is formed with a platform, a metal screw which is simultaneously formed via injection molding with an outer plastic shell of the sensor is arranged on the platform and the lower end of the metal screw is extended with a reverse hook having a smooth surface. The metal screw can rotate on the outer plastic shell, and a fixing piece of a metal cap nut is matched with the metal screw. The utility model adopts the fixing mode of supporting upwards and pressing downwards, namely the sensor is pressed down to fully and tightly contact with an air cylinder when the fixing piece of the cap nut is supported upwards. The effect of induction is enhanced, and simultaneously, the metal screw and the sensor are fixed together in an injection molding mode to cause the screwed screw to be not easy to disengage from the sensor without the damage to the sensor. The utility model has the advantages of simple structure and favorable using effect.
Description
Technical field:
The utility model relates to the sensor fastening device field, refers in particular to a kind of metal screw of fixing with sensor plastic casing while injection molded, and the sensor construction of the fixing rotatable screw of the rotatable injection moulding of screw.
Background technology:
As accompanying drawing 1, the present employed sensor fixed sturcture of people, mainly be that screw O2 directly is screwed in the plastics thread through hole on the sensor O3, again screw O2 is screwed down until the bottom of pushing up cylinder O1 groove, thereby sensor O3 is moved up, push up the groove top of cylinder O1 and be fixed until sensor O3 upper end.This fixed form is owing to be break-in between the plastics thread of screw O2 and sensor O3, be easy to damage the plastics thread of sensor O3, and this mode is that sensor O3 is suspended from the groove upper end, so sensor O3 and cylinder O1 contact effect and fixed effect is all bad, thereby cause sensor O3 inductive effects not good.
As accompanying drawing 2, other plants present employed sensor fixed sturcture, is to utilize the lower end that screws screw O4 to have a barb to suppress in the corresponding bayonet socket that embeds sensor O3 front end, because of narrow and small, the fragile structure of front-end architecture volume of sensor O3; Very easy because of being pressed into when screwing screw O4, with the structural failure of bayonet socket.And when using, also be very easy to structural failure with bayonet socket, make sensor O3 to fix and damage.
The utility model content:
The purpose of this utility model is to overcome the defective of prior art, provide a kind of simple in structure, not fragile sensor construction, and can reliably sensor and cylinder groove be fit together, make the sensor construction of the fixing rotatable screw of the respond well injection moulding of sensor sensing.
For achieving the above object, the utility model is realized in the following way: sensor front end forms a platform, have on the platform and the fixing metal screw of sensor plastic casing while injection molded, the lower end of metal screw is extended with the barb with smooth surface.The metal screw can rotate on plastic casing, and is combined with the metal nut fixture.
The advantage of the utility model technology is simple in structure, and the fixing of screw finished through injection moulding, and screw and working of plastics are combined closely, and make that the structure of working of plastics is strengthened.Because the hardness of plastics is low and elasticity is big than the metal screw, the barb surfaces of metal screw is level and smooth, so the metal screw can rotate on plastic casing.The metal screw just rotates on plastic casing, do not force on the sensor working of plastics, so can not damage sensor construction, simultaneously, when the rotating metallic screw, the metal nut fixture is top and the mutual screens in cylinder groove top upwards, impel the metal screw with sensor to pressing down, and sensor and cylinder groove are fit together, fix firmly, the contact area of sensor and cylinder increases greatly, thereby improve the inductive effects of sensor, be suitable for applying.
Description of drawings:
Accompanying drawing 1 is existing sensor fixed sturcture synoptic diagram;
Accompanying drawing 2 is another existing sensor fixed sturcture synoptic diagram;
Accompanying drawing 4 is stereographic maps of the present utility model;
Accompanying drawing 5 is use synoptic diagram of the utility model embodiment;
Accompanying drawing 6 is use synoptic diagram of the utility model embodiment.
Embodiment:
See shown in the accompanying drawing 3,4, the utility model includes sensor 1, sensor 1 front end forms a platform 11, has on the platform 11 and the fixing metal screw 2 of sensor 1 plastic casing while injection molded, and the lower end of metal screw 2 is extended with the barb 21 with smooth surface.
The fixed by nut part 3 metal screw 2 that is threaded, and be positioned on the platform 11 of sensor 1.The utility model fixed by nut part 3 has flange, and its breadth extreme is bigger than platform 11, will be blocked by the inwall of platform 11 during rotation.Metal screw 2 tops are the screw terminal with inner hexagonal hole or other shape, are used for spanner and rotate metal screw 2.
The utility model adopts metal screw 2 and the mode that sensor 1 plastic casing while injection molded is fixed together, and can make metal screw 2 be difficult for breaking away from sensor 1, does not damage sensor 1 structure simultaneously again.During use, with spanner that 2 rotations of metal screw are several down earlier, make the closely break-in in platform 11 of the level and smooth barb 21 in metal screw 2 lower ends, and screw out a gap, make the metal screw be easier to rotation, and then fixed by nut part 3 is spun on the metal screw 2.
Accompanying drawing 5,6 is depicted as the utility model sensor 1 and is applied to use synoptic diagram on the cylinder 4:
Sensor 1 is penetrated in cylinder 4 grooves, utilize hex wrench to insert in the inner hexagonal hole at metal screw 2 tops, clockwise direction rotating metallic screw 2 is because the barb 21 of metal screw 2 by the qualification of sensor 1 shell firmly, so metal screw 2 can only horizontally rotate and can not move up and down; Relative, fixed by nut part 3 is followed 2 rotations of metal screw, but blocked by the inwall on the platform 11 of sensor 1 and can not continue rotation, because threaded connection relation, fixed by nut part 3 moves up gradually and pushes up the flange on cylinder 4 groove tops until the flange of fixed by nut part 3, metal screw 2 downward jam sensors 1 made sensor 1 be close to the bottom that is fixed on cylinder 4 grooves firmly, thereby improved the inductive effects of sensor 1 greatly this moment.If counterclockwise rotating metallic screw 2 can get loose sensor 1 by contrary operation.
Because metal screw 2 just horizontally rotates on platform 11 and there do not have with the friction of plastic casing screw thread to be not stressed, so can not damage sensor 1.
The utility model adopts goes up the fixed form that the top presses down, promptly upwards to pressing down sensor 1 is fully closely contacted with cylinder sensor 1 simultaneously in the top by fixed by nut part 3, increased inductive effects greatly, simultaneously, employing makes metal screw 2 be not easy not damage sensor 1 again with sensor 1 disengaging the mode that metal screw 2 and sensor 1 injection moulding are fixed together.The utility model is simple in structure, result of use is preferable.
Certainly, the embodiment of the above, be the preferred embodiments of the utility model only, be not to limit the utility model practical range, so all do variation or modification according to the described structure of the utility model claim, feature and principle all should be included in the utility model claim.
