Definitions

  • the utility model relates to the field of sensor fixing devices, in particular to a metal screw which is injection-molded and fixed at the same time as a plastic outer shell of a sensor, and the sensor structure of the screw-rotatable injection-molded fixed rotatable screw.
  • the sensor fixing structure currently used is mainly to screw the screw 02 directly into the plastic screw through hole of the sensor 03, and then screw the screw 02 downward until it reaches the bottom of the groove of the cylinder 01.
  • the sensor 03 is moved upward until the upper end of the sensor 03 is pushed up to the top end of the groove of the cylinder 01 to be fixed.
  • This fixing method is easy to damage the plastic screw of the sensor 03 due to the running-in between the screw 02 and the plastic screw of the sensor 03, and this method is to suspend the sensor 03 at the upper end of the groove, so the sensor 03 and the cylinder 01
  • the contact effect and the fixing effect are not good, and the sensor 03 does not perform well.
  • another sensor fixing structure currently used is that a barb is strongly pressed into the corresponding bayonet of the front end of the sensor 03 by the lower end of the tightening screw 04, because the front end structure of the sensor 03 is small in size and fragile; When the screw 04 is pressed in, the structure of the bayonet is broken. Moreover, it is very easy to break the structure of the bayonet when used, so that the sensor 03 cannot be fixed and damaged.
  • the purpose of the utility model is to overcome the defects of the prior art, to provide a simple structure, not easy to damage the sensor structure, and to reliably fit the sensor and the cylinder groove in the Together, the sensor structure of the injection-molded fixed rotatable screw that makes the sensor feel good.
  • the utility model is realized as follows: The front end of the sensor is formed with a platform, and the platform has a metal screw which is injection-molded and fixed at the same time as the plastic shell of the sensor, and the lower end of the metal screw extends with a barb having a smooth surface. The metal screws can be rotated on the plastic housing and fitted with metal nut holders.
  • the advantage of the utility model is that the structure is simple, the fixing of the screw is completed by injection molding, and the screw and the plastic part are tightly combined, so that the structure of the plastic part is strengthened. Since the hardness of the plastic is lower than that of the metal screw and the elasticity is large, the barb surface of the metal screw is smooth, so that the metal screw can be rotated on the plastic case. The metal screw only rotates on the plastic housing and does not apply force to the sensor plastic part, so the sensor structure is not damaged. At the same time, when the metal screw is rotated, the metal nut fixing member is locked up to the top of the cylinder groove. The metal screw pushes the sensor down, and the sensor and the cylinder groove are closely attached, and the contact area between the sensor and the cylinder is greatly increased, thereby improving the sensing effect of the sensor and being suitable for popularization and application.

  • the nut fixing member 3 Gradually move up until the flange of the nut holder 3 tops the flange of the top end of the groove of the cylinder 4, at which time the metal screw 2 presses down the sensor 1 so that the sensor 1 is firmly attached to the groove of the cylinder 4 At the bottom, the sensor 1 is greatly improved. If the metal screw 2 is rotated counterclockwise, the sensor 1 can be reversed to release the sensor 1. Since the metal screw 2 is only horizontally rotated on the platform 11 and is not subjected to friction with the plastic casing thread, the sensor 1 is not damaged.
  • the utility model adopts the fixing method of the top and bottom pressing, that is, the nut 1 is pressed upward by the nut fixing member 3 and the sensor 1 is pressed downward, so that the sensor 1 and the cylinder are in full close contact, thereby greatly increasing the sensing effect, and at the same time, adopting the gold
  • the method in which the wide screw 2 and the sensor 1 are injection-molded together makes the metal screw 2 not easily detached from the sensor 1 without damaging the sensor 1.

Abstract

L'invention porte sur une structure de curseur présentant une vis tournante encastrée lors du moulage par injection. La partie frontale du curseur comporte un méplat sur lequel est fixé une vis métallique intégrée au corps plastique du curseur au moment du moulage. La surface inférieure de la vis se prolonge par une collerette à surface lisse. Lorsqu'on tourne la vis dans le curseur, un écrou apparié vissé sur elle est poussé vers le haut, ce qui repousse vers le bas le curseur qui vient buter contre un cylindre. L'encastrement de la vis dans le curseur lors du moulage rend difficile sa séparation du curseur et empêche de l'endommager.
