Abstract
A steel ball slide rail is provided. The internal rail of the utility model is arranged in the external rail trough and implements the slide connection with the external rail trough by the steel balls at two side walls. The front end of the external rail trough is provided with an internal position limit salient which prevents the ball nest from sliding and disconnecting; the rear half section of the external rail trough is provided with an internal position salient which aims at the ball nest; the rear end is provided with a rear retaining plate which aims at the internal rail position limit and is upswept formed after stamped. The utility model adopts the rolling parts and stamping parts; the position limit salient also adopts stamping molding. The global modeling is simple, smooth and not easy to be damaged, and has small and good parts; the product production and assembly are simple and easy; the cost is low; the application effect is good; the impact of the internal rail on the rear baffle of the external rail is basically avoided and relieved; the overturn caused by the mutual disconnection of the internal and external rail can not occur; the strength is higher and the utility model can bear more strong drawing impact force.
Description
Technical field
The utility model relates to a kind of two joint steel ball slide rails, is meant a kind of reinforced structure of two joint steel ball slide rails that can be used for various drawers especially.
Background technique
Traditional rail structure mainly is to be nested with interior rail in the outer rail groove, and when slide rail was fixed at the object outside, being slidingly matched between rail and outer rail groove made object can be able to pull swimmingly in utilizing.But when interior rail is retracted in the outer rail groove fully, because of no any limit structure in the outer rail groove makes it to be blocked, so object is easy to be subjected to external force effect such as user's misoperation or exerts oneself excessive and vibrations etc. and skid off the outer rail groove, this both might cause the accident of object to turn over side, also may cause the personnel that are in the object outside to be collided, and when the inner outside accident of drawer that carries weight skids off, cabinet is toppled over because of centre-of gravity shift.The improvement project of Ti Chuing has many at this point, China's No. 1.1 patents of ZL0224795 " drawer sliding rail with anti-slip device " promptly are one, this design proposal comprises members such as outer rail groove, interior rail bar and anti-slip device, its anti-slip device is mounted on the end of outer rail groove, is made up of members such as a pedestal, a slide and spacing guide pillars; Make the spacing guide pillar can be when pedestal and the mutual slide displacement of slide, slippage dislocation and form the state of threading off or colluding lock together with the interior rail bar of drawer sliding rail, can drawer sliding rail when closing, be had in condensation prevent to deviate from and can fast drawer be returned to the effect of location by the elastic element effect of being located between pedestal and slide like this from line slip.Though this design proposal may have preferable effect, obvious complex structure, customer using cost is too high, and market prospects allow of no optimist.
The model utility content
The problem that the utility model need solve provide a kind of intensity high and simple in structure, can effectively prevent the two joint steel ball slide rails that object is deviate from or turned on one's side.
A kind of two joint steel ball slide rails have been designed according to the above-mentioned problem that needs to solve, comprise outer rail groove and interior rail, interior rail is contained in the outer rail groove and by the steel ball and the outer rail groove of two side and realizes being slidingly connected, steel ball is arranged in the grooved pearl nest, front end at the outer rail groove is provided with the inside spacing preiection that prevents the slippage of steel ball pearl nest, the tail end of interior rail be provided with cooperate with steel ball pearl nest be used to prevent in the position-limited block of rail slippage, rail washer in the middle front part of interior rail also is provided with spacing that another cooperates with steel ball pearl nest.Wherein, inwardly spacing preiection is positioned in the middle of the bottom land of outer rail groove or is positioned on the both sides cell wall of outer rail groove and mapping mutually.Simultaneously, also can inside spacing preiection at grooved pearl nest be set in second half section of outer rail groove, this spacing preiection also is to be positioned in the middle of the bottom land of outer rail groove or to be positioned on the both sides cell wall of outer rail groove and mapping mutually.In addition, the tail end of outer rail groove upwarps formation at the spacing back plate washer of interior rail after punching press.
The utility model almost completely adopts punching press and roll extrusion part, spacing preiection also adopts impact briquetting, moulded simple smoothness, intensity height, not fragile, component are fewer but better, production and assembling are easily simple, and cost is low, and using effect is good, basically avoid and slowed down interior rail to outer rail after the impact of plate washer, outer rail does not break away from toppling of causing mutually in can not occurring in yet.
Description of drawings
Accompanying drawing 1 is that the master after the utility model assembling looks perspective view; Accompanying drawing 2 is that the master of outer rail groove in the accompanying drawing 1 looks perspective view; Accompanying drawing 3 is that the master of interior rail bar in the accompanying drawing 1 looks perspective view.
Embodiment
The utility model is by optimized Structure Design, with scheme under the prerequisite of proof strength, further to ensure accuracy that product is spacing and alleviation in addition avoid in rail to the impact of outer rail groove tail end plate washer.Below in conjunction with embodiment design proposal of the present utility model is described in further detail.
Main body of the present utility model is a grooved outer rail groove 1, its tail end through punching press upwarp form make the afterbody sealing after plate washer 11, the interior rail 2 that has guaranteed to be contained in wherein can not skid off from tail end.Interior rail also is grooved, is fastened in the outer rail groove.By also being connected and locating, on the two side of interior rail and outer rail groove, all have through roll forming groove for the steel ball walking is arranged between interior rail and outer rail groove for the steel ball pearl nest 3 of grooved.In order to guarantee that steel ball pearl nest does not skid off when the outside pulling from the outer rail groove, special front end at the outer rail groove is provided with inside spacing preiection 13, and this spacing preiection is positioned in the middle of the bottom land of outer rail front of the slot or is positioned on the both sides cell wall of outer rail front of the slot and mapping mutually.Simultaneously, also be provided with inside spacing preiection 12 at steel ball pearl nest in the second half section of outer rail groove, this spacing preiection also is to be positioned in the middle of the bottom land of outer rail groove or to be positioned on the both sides cell wall of outer rail groove and mapping mutually.In order to cooperate with each spacing preiection on the outer rail groove, the tail end of interior rail be provided with cooperate with grooved steel ball pearl nest be used to prevent in the position-limited block 21 of rail slippage, rail washer 22 in the middle front part of interior rail is provided with, the stroke that has promptly limited the pearl nest has thus also limited the stroke of interior rail.Above-mentioned each projection and washer are all through drawing, and purpose is the restriction stroke and alleviates impact.
Wherein, mainly play and alleviate even what avoid percussion is interior spacing preiection 12 on the outer rail groove and the washer 22 on the interior rail.When pushing back drawer in the use, interior rail inwardly slides into end, washer on the interior rail is subjected to stopping of steel ball pearl nest, spacing preiection stopped in steel ball pearl nest was subjected in the outer rail groove, through this alleviation with avoided after plate washer 11 be subjected in rail long-term impact and be out of shape the interior outer rail that is caused and separate, exempted interior outer rail and broken away from mutually toppling of causing.
