Abstract
The invention relates to an infinite ball slide rail capable of realizing random extension lengths. The current three-section ball slide rail is changed from a structure of an outer layer slide rail, a middle layer slide rail and an inner layer slide rail to a structure of an outer side slide rail, a middle slide rail and an inner side slide rail, wherein the center distances of balls in an upper slide rail and a lower slide rail which are formed by the outer side slide rail, the middle slide rail and the inner side slide rail, thus persons can infinitely regulate the number of layers of middle slide rails according to practical requirements to realize random extension lengths. Under the condition that the widths of the slide rails are equal, the bearing capability of the three-section ball slide rail disclosed by the invention is greatly improved as compared with the bearing capability of the current three-section ball slide rail. The self width of each layer slide rail in the structure of the infinite ball slide rail is larger and spaces among the three layer of slide rails are also larger, thus the invention further provides a structure platform so as to design a novel structure and a product capable of acting various specific additional movements along with the extension or retraction of the ball slide rails. Therefore, the invention develops a fully novel product series, besides the current full-extension three-section ball slide rails.
Description
Technical field
The present invention relates to a kind of more piece ball slide rail that can realize any spread length, belong to the invention of mechanical railroad.
Background technology
Ball slide rail is widely used in occasions such as furniture, Tool Cabinet, server cabinet, vending machine.At present, the ball slide rail that level is maximum is three joint slide rails, and the maximum extension length of this type three joint slide rails is the length of ball slide rail self just, therefore often is called full exhibition ball slide rail.Usually, this type three joint ball slide rails all are made up of outer slide rail, middle level slide rail and internal layer slide rail.Because the centre-to-centre spacing of the ball in the up and down slideway that the centre-to-centre spacing of the ball in the up and down slideway that outer slide rail and middle level slide rail are constituted and middle level slide rail and internal layer slide rail are constituted is also inequality; Cause the width of these three layers of slide rails to have nothing in common with each other; Outer slide rail the wideest; Internal layer slide rail the narrowest, the width of internal layer slide rail generally has only about 40 to 60 percent of outer slide rail.The structures shape of this type three joint slide rails they can't develop into four joint slide rails, five joint slide rails or the like again.Although the spread length of this type three joint ball slide rails can reach full exhibition, it is not enough to still have many occasions when extracting maintenance out, often to dislike it to stretch such as industry enclosure.And, because the constriction greatly of having compared of width and the outer slide rail of the internal layer slide rail of these three joints ball slide rails, so;, these three joints ball slide rails will find that the width of internal layer slide rail is too narrow when being in full exhibition state; Be difficult to bear very big load, particularly in the time need applying a concentrfated load, at this moment at the place, end that the internal layer slide rail stretches out; In order to ensure the bearing capacity of slide rail, just can only change the three joint ball slide rails that choosing has wideer outer slide rail.In addition; Also have a kind of situation be existing three the joint ball slide rails can't take on; That is exactly when the needs ball slide rail is made other additional move when stretching out or withdraw; Because the width of middle level slide rail and the internal layer slide rail of these three joints ball slide rails is too narrow, and outer slide rail, middle level slide rail and internal layer slide rail press close to again each other very much, so its inner available space all too is little; Can't design office and realize this additional move, thereby limit some application of three joint ball slide rails.
Summary of the invention
In order to overcome the deficiency of existing three joint ball slide rails; The present invention proposes a kind of structure that can realize the ball slide rail of any spread length; A kind of structure of unlimited ball slide rail just; This ball slide rail with the situation of the same width of existing three joint ball slide rails under can improve bearing capacity significantly; And since the width of each layer of this ball slide rail itself more greatly and space each other also bigger, so can be used to design various offices to realize various additional move.
The technical scheme that the present invention adopted is: three joint ball slide rails are made into the structure be made up of outside slide rail, middle slide rail and inboard slide rail by the structure of existing outer slide rail, middle level slide rail and internal layer slide rail; Wherein, the centre-to-centre spacing of the ball in the up and down slideway that constitutes each other of the outside, centre and inboard three layers of slide rail is equal fully.Middle slide rail is put one deck more, just become the four joint ball slide rails that constitute by the outside, centre, centre and inboard four layers of slide rail.Middle slide rail is put one deck again, just become the five joint ball slide rails that constitute by the outside, centre, centre, centre and inboard five layers of slide rail.Obviously, the number of plies of slide rail in the middle of the present invention can unrestrictedly select according to actual needs, thus make ball slide rail can reach spread length arbitrarily.In addition; Under the outside slide rail width of the three joint ball slide rails of the present invention situation identical with the outer slide rail width of existing three joint ball slide rails; The width of inboard slide rail and the middle slide rail of three joint ball slide rails of the present invention has increased many than the width of the internal layer slide rail of existing three joint ball slide rails and middle level slide rail, this has improved the bearing capacity of ball slide rail undoubtedly significantly.And, structure of the present invention make each layer of slide rail itself width more greatly and space each other also bigger, make slide rail when stretching out or withdrawing, make various additional move thereby be convenient to design office, to satisfy the needs of some specific use.
The invention has the beneficial effects as follows: the present invention can realize the ball slide rail of four joints, five joints even any more piece, thereby reaches spread length arbitrarily.The bearing capacity of ball slide rail of the present invention under the identical situation of slide rail width, is greatly improved than existing three joint ball slide rails.The present invention also provides a structure platform, can design stretching out or withdraw and make the novel structure and the product of various specific additional move along with ball slide rail whereby.Therefore, the present invention will hew out a brand-new product line outside existing full exhibition three joint ball slide rails.
Shortcoming of the present invention is big than existing ball slide rail of the thickness of ball slide rail, so be fit to be applied in the occasion that thickness is not had strict demand.
