Description

The front end guide and limit structure of three-section type sliding track

Technical field

The present invention relates to slide rail field, specially the front end guide and limit structure of three-section type sliding track.

Background technology

It is generally used for using the three-section type sliding track that bearing capacity is higher more than the slide rail of drawer type server cabinet, its China and foreign countries is sliding Rail is fixed on server cabinet, and interior slide rail is connected on drawer type cabinet body, by middle slide rail between interior slide rail and external slide rail It is slidably connected.Under normal circumstances drawer type cabinet body when being assembled on server cabinet mostly be by drawer type cabinet body directly with interior cunning Rail is affixed, but at some in particular cases, such as Large Copacity, the drawer type server of big specification are located at taking out for rack upper strata in assembling During drawer formula cabinet, generally require many personal lift to assembling height drawer type cabinet body drawer type cabinet body is assembled with interior slide rail again Affixed, its assembly difficulty is big, efficiency of assembling is low；In the art also occurring in that first extracts simultaneously interior slide rail out from middle slide rail at present It is separately assembled on drawer type cabinet body, then by the way that slide rail in the middle of the insertion of interior slide rail is synchronous by drawer type cabinet body and server machine Cabinet is assembled in place, although this kind of mode can reduce the assembly difficulty of drawer type cabinet body, efficiency of assembling be improved, due to interior cunning Exist between rail and middle slide rail and gap is installed and pearl seat is also equipped between the two, be assemblied in the interior cunning on drawer type cabinet body Easily there is the phenomenon stuck with middle slide rail in rail grafting when entering middle slide rail, while easily producing impact to pearl seat so as to cause pearl seat Deformation, the normal of influence slide rail is used.

The content of the invention

Regarding to the issue above, the invention provides the front end guide and limit structure of three-section type sliding track, it can solve existing three Section type sliding track is easily stuck with middle slide rail present in slide rail process in the middle of interior slide rail loads and causes because of impact pearl seat The problem of pearl seat deformation.

Its technical scheme is that the front end guide and limit structure of three-section type sliding track, the three sections slide rail includes being fixed in service The interior slide rail and the interior slide rail that is slidably connected of external slide rail and the drawer type cabinet body connection of device rack, the middle of external slide rail are slided Rail, the middle slide rail includes the base plate extended along external slide rail length direction, and being symmetrically arranged on two with for the base plate is upturned Side wall, the base plate includes central bottom plate and sidepiece base plate, and the both sides of the central bottom plate are by bending separately down Connecting portion is symmetrically connected with the sidepiece base plate, it is characterised in that：The base plate of the middle slide rail anterior end is provided with positioning Structure, is provided with a guide and limit part, the anterior end surface of the guide and limit part and the middle slide rail in the location structure Anterior end surface flush, the left and right sides of the guide and limit part is provided with symmetrical limiting section, two outsides of the limiting section Face coordinates with middle slide rail two side internal face respectively, medial surface is the spigot surface coordinated with interior slide rail two side walls.

Further, the medial surface of the front and back ends of the limiting section is equipped with to the tapered guiding surface in inner side.

Further, the guide and limit part includes the prelocalization bar being parallel to each other and rear locating rod, the prelocalization bar Frame shape entirety is connected into by the symmetrical limiting section respectively with the two ends of rear locating rod.

Further, the location structure hollows out groove including a Baltimore groove and, and the Baltimore groove is opened in the centre The leading section of the central bottom plate of slide rail, described to hollow out the rear end that groove is opened in the Baltimore groove, the Baltimore groove is hollowed out with described The both sides of groove all extend to the connecting portion, and the prelocalization bar of the guide and limit part is flush-mounted in the Baltimore groove, positions afterwards Bar be embedded in it is described hollow out in groove, and the prelocalization bar, the top surface of rear locating rod and the middle slide rail base plate Top surface engagement is flushed.

Further, the base plate thickness of the prelocalization bar, the thickness of rear locating rod and the middle slide rail is identical.

Further, the prelocalization bar, the bottom surface two ends of rear locating rod are respectively arranged with card base, and the card base blocks respectively In the Baltimore groove, hollow out groove two side ends and be located at the middle central bottom plate of slide rail and the connecting portion of both sides base plate.

Further, the guide and limit part is integrated the working of plastics of injection moulding.

The beneficial effects of the present invention are：It sets location structure and by location structure by the base plate of middle slide rail Guide and limit part is set, and the insertion of internal slide rail is on the one hand carried out by guide and limit part carries out effective guide effect so as to effectively prevent Only collided between interior slide rail and middle slide rail, spacing on the other hand is played to the pearl seat being arranged between middle slide rail and interior slide rail The deformation of pearl seat is caused when acting on, preventing interior slide rail quick insertion to the impact of pearl seat, so that it is guaranteed that the normal of slide rail is used.
