Three-dimensional motion guidance device

Abstract

This invention provides a three-dimensional motion guiding device, comprising: a guide rod body, a guide groove sleeve, and an outer sleeve. The guide rod body has a rod portion, and a stop portion of the rod portion has an arc groove. A movable collar is sleeved on the rod portion. The guide groove sleeve is sleeved on the guide rod body and screwed onto the movable collar by a plurality of screw fasteners and its movement is restricted by the stop portion. The guide groove sleeve has a central guide groove, a first oblique guide groove, and a second oblique guide groove, which can respectively connect and engage with the arc groove. A ball is disposed on the arc groove. The outer sleeve is sleeved on the guide groove sleeve. By pushing the movable collar, the ball can be guided from the central guide groove to the first oblique guide groove and the second oblique guide groove, respectively, thus easily controlling the smooth movement of the ball.

Claims

1. A three-dimensional motion guiding device, comprising: a guide rod body, wherein a rod portion is formed on the guide rod body, one end of the rod portion extends outward and protrudes to have a stop portion, an arc groove is formed on a side of the stop portion, a movable collar is sleeved on the rod portion, one end of the movable collar extends outward and has a limiting portion, an annular groove is formed on the side of the limiting portion, and a spring is sleeved on the rod portion; A guide sleeve has a central guide groove formed on it. One end of the central guide groove extends outward to two opposite sides to form a horizontal guide groove. One end of the horizontal guide groove extends outward at an inclined angle to form a first oblique guide groove, and the other end extends outward at an inclined angle to form a second oblique guide groove. A limiting part is formed at the inner center of one end of the guide sleeve. An expansion part is formed at the other end of the guide sleeve. A plurality of screw holes are formed on the side of the expansion part. The guide sleeve is sleeved on the guide rod body from the blocking part position. The other end of the central guide groove is connected to the arc groove. The plurality of screw holes are connected to the annular groove and are screwed into the annular groove by a plurality of screw fasteners using the plurality of screw holes. This allows the guide sleeve to be assembled and connected with the movable collar. A ball is disposed on the arc groove. An outer sleeve is fitted onto the guide groove sleeve, and the expansion portion restricts the movement of the outer sleeve.

2. The three-dimensional motion guidance device as described in claim 1, wherein, The spring is sleeved on the rod and is located between the stop and the limiting part.

3. The three-dimensional motion guidance device as described in claim 1, wherein, The guide sleeve is cylindrical.

4. The three-dimensional motion guidance device as described in claim 1, wherein, The central guide groove, the transverse guide groove, the first oblique guide groove, and the second oblique guide groove are all formed at a vertical angle.

5. The three-dimensional motion guidance device as described in claim 1, wherein, The limiting part is restricted from continuing to move by the blocking part.

6. The three-dimensional motion guidance device as described in claim 1, wherein, All of these multiple locking holes are located on the same axis.

7. The three-dimensional motion guidance device as described in claim 1, wherein, The outer sleeve is cylindrical.
