Abstract
The invention relates to a limitlessness slide rail realizing random spreading length, and belongs to a machine slide rail device. A limitlessness ball bearing slide rail and a limitlessness sliding slide rail can realize random spreading of length in the prior art, and then, the widths of each layer of slide rails of these limitlessness slide rail devices are same except inner side slide rails. The characteristic becomes an obstruction in an application occasion, because other occasions have different strength and rigidity requirements on the root of the limitlessness slide rail and the spreading end and thus, the prior art can not be adopted. Therefore, the invention provides the limitlessness slide rail structure with two slide rail widths gradually changing in arithmetical progression, so that the problem is solved, and the application occasion of the limitlessness slide rail is further enlarged.
Description
Technical field
The present invention relates to a kind of unlimited slide rail that can realize any spread length, belong to the invention of mechanical railroad.
Background technique
Application number is the structure that 201110274786.2 invention has proposed unlimited ball slide rail, and application number is the structure that 201110287026.5 invention has proposed unlimited slip slide rail.In the rail structure of these two inventions, except the width of inboard slide rail was less, the width of other all slide rails (comprising outside slide rail and all middle slide rails) all equated.Yet, need to use in the occasion of unlimited slide rail at some, but because all equating, the width of outside slide rail and middle slide rail goes wrong; And in the other occasion, with the end of stretching away the requirement of different intensity and rigidity is arranged because of the root to unlimited slide rail again, thereby also can't adopt said structure.Therefore, be necessary to develop and a kind ofly can overcome the new structure of the unlimited slide rail of " width of outside slide rail and all middle slide rail is all equal " this defective.
Summary of the invention
The present invention proposes the structure of the unlimited slide rail that can realize any spread length that two kinds of slide rail width change gradually, and wherein, a kind of is the structure of ball slide rail, and a kind of is the structure of slip slide rail.
The technical solution used in the present invention is: the width of outside slide rail, middle slide rail and inboard slide rail in above-mentioned two patent structures is made gradually to some extent variation; The number of plies of middle slide rail is decided according to the actual requirements, can be from one deck to the N layer; The slide rail of all layers is all pulled folding with single piece of sheet metal and is formed; Ball slide rail can be made, also the slip slide rail can be made; In ball slide rail, formed the raceway of rolling element by cooperatively interacting of adjacent slide rail, rolling element is steel ball, the rolling element in the whole device all is same diameter; In the slip slide rail, outside slide rail is provided with a pair of up and down slideway, middle slide rail is provided with a pair of up and down draw runner and a pair of up and down slideway, inboard slide rail is provided with a pair of up and down draw runner, the slideway cross section is semicircle, the draw runner cross section also is semicircle, and the semicircular radius in the semicircular radius ratio slideway cross section in draw runner cross section is slightly little, and the size of all draw runner slideway relations is identical in the whole device; From outside slide rail to inboard slide rail, the centre distance of the ball about the ball slide rail in the twice raceway and slip the slide rail up and down end distance on earth of twice slideway all are the arithmetic series variation.
The invention has the beneficial effects as follows the application of having widened unlimited slide rail.
Description of drawings
Fig. 1 is the drawing in side sectional elevation of the unlimited ball slide rail of eight joints.
Fig. 2 is the perspective view of the unlimited ball slide rail of eight joints.
Fig. 3 is the drawing in side sectional elevation of the unlimited slip slide rail of six joints.
Fig. 4 is the perspective view of the unlimited slip slide rail of six joints.
Embodiment
The embodiment of the invention one be a kind of eight the joint unlimited ball slide rails, its drawing in side sectional elevation as shown in Figure 1, its perspective view is as shown in Figure 2.The embodiment of the invention two be a kind of six the joint unlimited slip slide rails, its drawing in side sectional elevation as shown in Figure 3, its perspective view is as shown in Figure 4.Usually, outside slide rail is affixed with the body that railroad is set, and inboard slide rail is then affixed with the parts that need slippage.
Claims (1)
1. unlimited slide rail, it is characterized in that: unlimited slide rail is by one deck outside slide rail, one deck to the middle slide rail of N layer and the inboard slide rail of one deck consists of, the slide rail of all layers is all pulled folding with single piece of sheet metal and is formed, the width of the slide rail of all layers changes gradually, unlimited slide rail can be ball slide rail, it also can be the slip slide rail, in ball slide rail, formed the raceway of rolling element by cooperatively interacting of adjacent slide rail, rolling element is steel ball, rolling element in the whole device all is same diameter, in the slip slide rail, outside slide rail is provided with a pair of up and down slideway, middle slide rail is provided with a pair of up and down draw runner and a pair of up and down slideway, inboard slide rail is provided with a pair of up and down draw runner, the slideway cross section is semicircle, the draw runner cross section also is semicircle, the semicircular radius in the semicircular radius ratio slideway cross section in draw runner cross section is slightly little, the size of all draw runner slideway relations is identical in the whole device, from outside slide rail to inboard slide rail, the centre distance of the ball about the ball slide rail in the twice raceway and slip the slide rail up and down end distance on earth of twice slideway all are the arithmetic series variation.
