Description

Railroad

Technical field

The utility model relates to a kind of railroad, particularly relates to a kind of slide rail distortion that can prevent to break away, rocks, and makes the railroad of slide rail sliding stability.

Background technique

Slide rail is the device of comparison precision, and the tolerance of size of parts key all needs to be controlled within 0.01mm～0.02mm.And slide rail is to need the parts of slip mutually, needs to reserve certain fit up gap.Slide phone, in the time of production the most scabrous problem be exactly rocking of slide rail and because the distortion of slide rail causes renovating and main frame between the gap can not be well controlled.

At present, the structure of existing slide rail is to adopt one first slider 1 ' semi-surrounding one second slider 2 ' as shown in Figure 1 to Figure 3.First slider 1 ' of the prior art needs bending, then an acetal resin colloid is assembled into, first slider 1 ' is all bigger usually with the lateral clearance and the axial clearance that exist between the acetal resin, and this occurs rocking when making the slider 1 ' of winning follow between second slider 2 ' slip.

In addition, because first slider 1 ' needs bending second slider 2 ' could be coated, this can not get better controlled with regard to the planeness that makes the slider 1 ' of winning, and the time has been grown certain deformation can take place.Secondly, if the acetal resin colloid adopts in-mould injection, through the high temperature of mould, the sheet metal part stress relief after the bending, the flatness of first slider 1 ' can change, and the axial clearance that needs relatively also can become big.If the acetal resin colloid is assembled into first slider 1 ' after being, because assembly error arranged, the thickness of acetal resin colloid is thinner again simultaneously, be out of shape bigger, therefore need to reserve laterally, the axial clearance is also just bigger.In addition, second slider 2 ' is that the face face cooperates with the acetal resin colloid, and frictional force is big when therefore sliding, and also can cause the matching gap linear amplification of whole slide rail during slip, thereby rocks when causing slide rail to use seriously, is difficult to control.

The model utility content

The technical problems to be solved in the utility model is to rock seriously in order to overcome to exist when existing slide rail assembles, and unmanageable defective provides a kind of and can prevent slide rail distortion, the railroad that rocks when avoiding the slider slippage.

The utility model solves above-mentioned technical problem by following technical proposals: a kind of railroad, it comprises one first slider and one second slider, its characteristics are, described railroad also comprise two with the affixed guide member of described first slider, the both sides of described second slider respectively are provided with a chute, and two described guide members activity respectively are set in two chutes.

Preferably, described first slider comprises one first sheet metal part and one second sheet metal part, and the described second slider activity is located between described first sheet metal part and second sheet metal part.

Preferably, described first sheet metal part and second sheet metal part flexibly connect by described guide member and described second slider.

Preferably, the cross section of described first sheet metal part and described second sheet metal part is a plane.

Preferably, described guide member is at least one guide pillar.

Preferably, described guide member is two groups, and every group is two.

Preferably, each described guide member is equipped with a roller outward.

Preferably, the cross section of described roller is an I-shaped shape.

Preferably, the middle part of described roller is provided with one and is used for the through hole that wears with described guide member.

Positive progressive effect of the present utility model is: the utility model can prevent the slide rail distortion, and the slider of avoiding cooperatively interacting rocks when slippage, stability and fastness when having improved the use of mobile phone slide rail.

Embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.

Extremely shown in Figure 5 as Fig. 4, the railroad that the utility model provides comprises: one first slider 1 and one second slider 2, the both sides of second slider 2 respectively are provided with a chute 21, the two ends of first slider 1 are set on guide member 3 in the chute 21 of second slider 2 by one group of activity respectively, make the slider 1 of winning do linear slippage along its chute 21 by relative second slider 2.

Preferably, every group of guide member 3 specifically can be two guide pillars.

In addition, on guide member 3, also be arranged with a roller 4.Roller 4 can adopt the acetal resin in-mould injection, is molded directly within outside the guide member 3.The part of the cross section of roller 4 and support block 5 is the I-shaped shape, offers a through hole that is used for wearing guide member 3 on the roller 4.Can reduce the wearing and tearing when sliding like this, the stationarity when strengthening slippage.

First slider 1 of the present utility model comprises that a cross section is first sheet metal part and one second sheet metal part of horizontal plane.Second slider 2 is located between first sheet metal part and second sheet metal part, and first sheet metal part and second sheet metal part such as being riveted joint, can make first slider, 1 relative second slider 2 do linear slippage along chute 21 by affixed with guide member 3.Guide member 3 is affixed with first sheet metal part and second sheet metal part, forms first slider 1.

Like this, first slider 1 does not need bending, also can under the drive of guide member 3, slide by relative second slider 2, therefore, and the good relatively control of planeness, the axial clearance of required reservation simultaneously also can be more smaller.

Secondly,, have only the leave from office terrace of roller 4 and side to follow the wall of chute 21 to contact, play the slide guide effect because roller 4 is to be set on the guide member 3.First slider 1 is adjusted by the diameter of four rolling 4 with the control of the lateral clearance of second slider 2, and first slider 1 then can be adjusted by the height of support block 5 with the axial clearance of second slider 2.Height control when assembling between first sheet metal part and second sheet metal part also can highly be adjusted by the support block 5 that adopts the acetal resin molding and forming.Simultaneously, it is the thermoplastic engineering plastic of high density, high-crystallinity for an acetal resin (english abbreviation POM), has good physics, machinery and chemical property, and excellent crocking resistance is especially arranged.Therefore, roller has the effect of good slide guide, and like this, when these sliders fitted together, lateral clearance, the axial clearance of reservation can be relatively littler, only need guarantee that first slider can slide relative get final product with second slider.

In addition, the roller that adopts acetal resin to make in the present embodiment, the contact of following second slider 2 is that the line face cooperates, therefore friction is less relatively, the stationarity when having guaranteed to slide.

Guide member of the present utility model is provided with the roller that the cross section is T word shape outward, add support block and partly form the I-shaped structure, first slider and second slider well can be cooperated, horizontal and vertical gap between the slide rail like this, by four rolling and support block 5 controls, therefore, avoided the linear amplification of slide rail matching gap of the prior art.

The utility model is that the structure that two sliders of slide rail cooperate has been done change, make slide rail rock and distortion is well controlled.

The whole processing and fabricating part of above-mentioned second slider, and support block 5 is the state of the art at the in-mould injection moulding section by acetal resin, do not give unnecessary details at this.

Though more than described embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art can make numerous variations or modification to these mode of executions under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection domain of the present utility model.
