Summary of the invention
The present invention has overcome the deficiencies in the prior art, and a kind of a kind of rectangle guide pillars and bushes simple in structure is provided.
For achieving the above object, the technical solution used in the present invention is: a kind of rectangle guide pillars and bushes, comprise: guide pin bushing, be set in the ball distance ring in described guide pin bushing and be set in the guide pillar in described ball distance ring, and be set in the first flat spring on described guide pillar and be positioned at the second flat spring of described guide pin bushing, it is characterized in that: described guide pin bushing, described ball distance ring, described guide pillar, described the first flat spring and described the second flat spring are the column structure that cross section is rectangle, on described ball distance ring, be placed with several retaining holes, described retaining hole is embedded with ball, the top and bottom of each circle of described the first flat spring and described the second flat spring are planar structure.
In a preferred embodiment of the present invention, described retaining hole runs through described ball distance ring sidewall, and described ball protrudes described retaining hole two ends.
In a preferred embodiment of the present invention, described guide pin bushing one end is provided with inside step, and described step center has hole, and described guide pillar diameter is greater than described bore dia.
In a preferred embodiment of the present invention, described guide pillar one end is provided with edge clipping, and described the first flat spring is between described edge clipping and described ball distance ring, and described the second flat spring is between described ball distance ring and described step.
In a preferred embodiment of the present invention, the internal diameter of described the first flat spring and described the second flat spring is all greater than described guide pillar external diameter and external diameter is all less than described guide pin bushing internal diameter.
In a preferred embodiment of the present invention, the first flat spring and coaxial being set-located of described the second spring described in described guide pin bushing, described ball distance ring, described guide pillar.
In a preferred embodiment of the present invention, in the gap between described guide pin bushing and described guide pillar of described ball clamping.
The invention solves the defect existing in background technology, novelty of the present invention convert guide pillars and bushes shape of cross section to rectangle, can use up like this mould that utilizes of large limit arranges, the guide pin bushing of a rectangle guide pillar is also individual can adapt to rectangular mould, the present invention simultaneously also relates to spring in orthogonal spiral, and the upper and lower surface of the every circle of spring is designed to plane, avoid circular cross-section spring to be compressed to the phenomenon being damaged after the limit.

The specific embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only shows the formation relevant with the present invention.
As shown in Fig. 1-6, a kind of rectangle guide pillars and bushes, comprise outermost guide pin bushing 2, the guide pillar 4 that the ball distance ring 6 that guide pin bushing 2 inside are provided with and ball distance ring 6 internal sleeve have, wherein the first flat spring 12 is set on guide pillar 4, its two ends are fastened on middle by ball distance ring 6 one end and edge clipping 16 respectively, the second flat spring 14 is arranged in guide pin bushing 2 and is fastened on middle by ball distance ring 6 one end and step 18, ball distance ring 6 is provided with some row and several rows retaining hole 10, retaining hole 10 runs through ball distance ring 6 sidewalls, each retaining hole 10 inner sleeve has ball 8, ball 8 has two to expose retaining hole 10 two ends parts.
Guide pin bushing 2, guide pillar 4, ball distance ring 6, the first flat spring 12 and the second flat spring 14 are the structure that cross section is rectangle, and the width of guide pin bushing 2 and length are two ball 8 diameters and guide pillar 4 width and length sum, guide pillar 4 can move at guide pin bushing 2 internal freedoms under the effect of ball distance ring 6 like this, the shape of the first flat spring 12 and the second flat spring 14 is and guide pin bushing 2 and guide pillar 4 form fit, and upper surface and the lower surface of every circle are plane, such the first flat spring 12 and the second flat spring 14 after being compressed to minimum length, can avoid circular cross-section spring two adjacent rings because the phenomenon of the mutual damage that extruding causes, flat shape can increase the pressure-bearing pressure of two adjacent rings.The step 18 of guide pin bushing 2 one end can carry out guide pillar 4, the second flat spring 14 and ball distance ring 6 spacing, and edge clipping 16 can carry out spacing to the upper end of the first flat spring 12.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, related personnel can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on description, must determine technical scope according to claim scope.
