Abstract

The utility model relates to an improved structure of a sliding rail set. The left and the right sides of a drawer are respectively provided with an inner rail, a stopping sheet is arranged outside the inner rail, and the stopping sheet is provided with a raised and stereo ladder-shaped raised point. A steel ball grooved rail and a middle rail are contained in an outer rail; for the steel ball grooved rail, a fastening groove forming a notch shape and a fastening raised stopper of an elastic sheet of a guide sleeve of the middle rail are embedded and fastened with each other into one body. When assembled on the outer rail, the drawer can easily enter the steel ball grooved rail from the middle rail under the guide of the one body formed from the fastening of the steel ball grooved rail and the middle rail, and the steel ball grooved rail can be disengaged from the fastening of the middle rail to be flexibly slid with the drawer under the action that a pressing raised part on the guide sleeve of the middle rail is pushed and pressed by the raised point of the stopping sheet of the inner rail of the drawer to carry out displacement; accordingly, the steel ball grooved rail can be easily installed and can not be prevented from damage caused by the improper assembly.

Description

The improvement structure of slide rail set

Technical field

The utility model is relevant for a kind of improvement structure of slide rail set, and particularly a kind of being used for can successfully be assembled to middle orbit, the steel ball grooved rail of outside track when drawer is assembled, and can protect the steel ball grooved rail unlikely because of assembling the improper structure of sliding rail assembly that is damaged.

Background technology

General relevant be used in such as institute's power supply brain keyboard in the computer desk place with and cabinet can supply activity to pull out drawer, its dual-side at this drawer is pacified an inner orbit A respectively, on the both sides, position of placing an outside track B is installed then for drawer, one steel ball grooved rail C, middle orbit D are arranged (as Fig. 1-A) among this outside track B, steel ball grooved rail C position is sliding mode fully freely in middle orbit D, so, when drawer will be assembled in outside track B, then align and slip into and to form movable the contact with steel ball grooved rail C, middle orbit D; Yet as the inner orbit A of drawer dual-side during at middle orbit D for preparing to place outside track B and steel ball grooved rail C, because steel ball grooved rail C is not but in the cause of the foremost position of middle orbit D, so that inner orbit A is after entering middle orbit D, do not align steel ball grooved rail C, on the contrary steel ball grooved rail C is pushed open, this moment, general user can think that is just tight a little, just firmly push again, so that cause whole steel ball grooved rail C to produce deformed damaged, even steel ball C1 also can drop out (as Fig. 1-B) being subjected to improperly thrust.

Therefore, the creator just develops this case creation, and gives and filing an application.

Novel content

Main purpose of the present utility model, a kind of improvement structure of slide rail set is being provided, can be for movable structure of pulling out the drawer use, concrete structure is as follows: a kind of improvement structure of slide rail set, and arranged on left and right sides limit at drawer respectively has an inner orbit, it is characterized in that: this inner orbit appearance also has a catch that drawer is separated with outside track, and also has the catch salient point that is three-dimensional trapezoidal shape of a projection on catch; Also have a steel ball grooved rail and a middle orbit in the outside track, should have a guide pin bushing foremost, have a flexure strip on this guide pin bushing, and have pushing protuberance and fastening protruding retaining of a projection on the flexure strip at middle orbit; Have a steel ball grooved rail in that the guide pin bushing of middle orbit is other, the foremost position adjacent with the flexure strip of guide pin bushing has a buckling groove that is nick shaped in this steel ball grooved rail.

In view of the above, the buckling groove of steel ball grooved rail is subjected to the buckle of the protruding retaining of fastening of flexure strip of guide pin bushing in the middle orbit and becomes one under spacing; When drawer is assembled in outside track; can be by under the one guiding that steel ball grooved rail and middle orbit fastened; can very successfully enter the steel ball grooved rail by middle orbit; be pushing under the protuberance displacement on the guide pin bushing of pushing middle orbit by the catch salient point of the inner orbit of drawer more simultaneously; make the steel ball grooved rail break away from the fastening of middle orbit just now; and slide flexibly mutually with drawer, therefore to reach smooth installation and to protect the steel ball grooved rail unlikely because of assembling improper being damaged.

The specific embodiment

At first, please cooperate and consult Fig. 2-A, Fig. 2-B, shown in the detailed description of Fig. 2-C: the improvement structure of a kind of slide rail set of the utility model, the activity of applying to is pulled out in the use of drawer, it is on the left side of drawer, right dual-side is respectively installed an inner orbit 1, its inner orbit 1 appearance also has a catch 11, play the effect that drawer is separated with outside track 2 by the start of this catch 11, and on catch 11 and a projection is arranged and be the catch salient point 111 of three-dimensional trapezoidal shape: and at the relative position of 2 inner orbits 1 in drawer of track, it includes a steel ball grooved rail 3 and middle orbit 4, this middle orbit 4 is equipped with a guide pin bushing 41 foremost, establish a flexure strip 411 on the guide pin bushing 41, and have pushing protuberance 412 and fastening protruding retaining 413 of a projection on the flexure strip 411; In addition the guide pin bushing in middle orbit 4 41 is other then is provided with a steel ball grooved rail 3, and the foremost position adjacent with the flexure strip 411 of guide pin bushing 41 has a buckling groove 31 that is nick shaped in this steel ball grooved rail 3.

In view of the above, steel ball grooved rail 3 and middle orbit 4 are satisfied steel ball grooved rail 3 are passed toward middle orbit 4 directions after being assembled in outside track 2, make the protruding retaining 413 of fastening of buckling groove 31 buckles guide pin bushing 41 in middle orbit 4 of steel ball grooved rail 3, and form as one (as Fig. 2-C); Thus, when drawer is prepared to be assembled in outside track 2, because button is the steel ball grooved rail 3 and middle orbit 4 guiding of one, make inner orbit 1 very successfully enter steel ball grooved rail 3 (as Fig. 3) by middle orbit 4, afterwards, the catch salient point 111 of the catch 11 of inner orbit 1 also pushes pushes protuberance 412 toward bottom offsets on the guide pin bushing 41 of middle orbit 4, makes steel ball grooved rail 3 break away from the fastening of middle orbit 4 just now, satisfy and contacted inner orbit 1 start, with flexible slide (as Fig. 4); Otherwise, when drawer will separate with outside track 2, then when pulling out outward, the buckling groove 31 that makes steel ball grooved rail 3 once again with middle orbit 4 in the protruding retaining 413 of fastening of guide pin bushing 41 buckle is spacing mutually, make when inner orbit 1 will be once again in conjunction with the time, can operate very suitablely, do not produce problem as traditional form had in meeting.

Therefore, the utility model passes through steel ball grooved rail 3 and middle orbit 4 first behavior one, to form guiding function, drawer successfully can be assembled and be finished, and can protect not reason assembling improper and being damaged of steel ball grooved rail 3.As seen the utility model has its progressive place really, meets the establishment key element of Patent Law, earnestly asks and awards accurate legal patent right establishment.
