Abstract
The utility model relates to an electrical equipment with prevent upside down function, including the installation shell, the one end of installation shell is equipped with the internal thread, and internal thread department screw has adjust knob, is equipped with the elastic component of assembly in the installation shell in adjust knob's inboard, and the elastic component is equipped with the axial hole, is equipped with one -way bearing in the axial hole, and one -way bearing interference fit is assembling the pivot in the one -way bearing in the axial hole, and the outer end of pivot is connected with the motor. Through adjust knob, realize the frictional force between elastic component and the one -way bearing, prevent one -way bearing upside down (skidding), with the pivot nonreversible that the motor links to each other, simple structure. And belongs to the mechanical technology field.
Description
Technical field
This utility model belongs to field of mechanical technique, especially relates to a kind of motor device with anti-reverse functions.
Background technology
Micro-machine is applied to every field, for instance kitchen appliance field. Along with the raising of people's living standard, kitchen utensils are also adopted by intellectuality and realize corresponding function. Such as some cabinet current, is built-in with the laying rack that can lift, and adopts motor to realize lifting. Due to the existence of laying rack self He the weight of article, laying rack receives a downward pulling force, the rotating shaft of motor receives the pulling force effect of bracing wire, causes upset, laying rack will landing downwards, have impact on the normal use of cabinet.

Detailed description of the invention
With reference to shown in Fig. 1. A kind of motor device with anti-reverse functions of this utility model, it is characterized in that: include mounting shell 1, one end of mounting shell 1 is provided with female thread 1.1, female thread 1.1 place screw thread has adjusting knob 2, is provided with the elastic component 3 being assemblied in mounting shell 1 in the inner side of adjusting knob 2, and elastic component 3 is provided with axial hole 3.1, unilateral bearing 4 it is provided with in axial hole 3.1, unilateral bearing 4 is interference fitted in axial hole 3.1, assembles rotating shaft 5 in unilateral bearing 4, and the outer end of rotating shaft 5 is connected to motor 6.
One end of described elastic component 3 and adjusting knob 2 medial surface offset, and the other end and mounting shell 1 offset.
Described elastic component 3 axial hole 3.1 is designed in through elastic component 3.
Described elastic component 3 is rubber parts.
Described unilateral bearing 4 outer wall is provided with Non-slip material.
Described Non-slip material is some protruding or netted striped.
Described adjusting knob 2 is working of plastics, and the outer face of adjusting knob 2 is provided with screw plate 2.1.
Operation principle of the present utility model is, rotating shaft 5 owing to connecting motor 6 matches with unilateral bearing 4, so normal condition lower rotary shaft 5 only can rotate forward, so having only to prevent the outer ring of unilateral bearing from not rotating, it is ensured that rotating shaft 5 is nonreversible, also imply that motor 6 will not reverse. Outer ring in order to ensure unilateral bearing 4 does not rotate, by increasing the frictional force between unilateral bearing 4 outer wall and elastic component 3, the size of frictional force realizes regulating by adjusting knob 2, when adjusting knob 2 screwin time, will extruding elastic component 3, elastic component 3 compresses after receiving extruding so that axial hole 3.1 internal diameter diminishes, so laminating is more tight and between guide bearing 4 outer wall, improves frictional force.
