Just right concave groove has been seted up respectively on the both sides wall of the tip of the closed direction of middle slide rail, and two embedded being of concave groove are equipped with one and are "worker" font direction stopper, and the direction stopper connects into holistic ejector pin, vertical web portion and sill bar including being "worker" font, and vertical web portion inlays and adorns in the concave groove, and the ejector pin card of direction stopper is in interior slide rail one side, sill bar card in outer slide rail one side.
Description
Technical Field
The invention relates to the field of sliding rails, in particular to a rear end guiding and limiting structure of a three-section type sliding rail.
Background
Generally, a three-section type slide rail with high bearing capacity is adopted as a slide rail for a drawer type server cabinet, wherein an outer slide rail is fixed on the server cabinet, an inner slide rail is connected to a drawer type cabinet body, and the inner slide rail is connected with the outer slide rail in a sliding manner through a middle slide rail. Generally, when the drawer-type cabinet body is assembled on the server cabinet, the drawer-type cabinet body is directly and fixedly connected with the inner slide rail, but under some special conditions, for example, when the drawer-type cabinet body on the upper layer of the cabinet is assembled on a drawer-type server with large capacity and large specification, a plurality of persons are often required to lift the drawer-type cabinet body to the assembling height and then assemble and fixedly connect the drawer-type cabinet body with the inner slide rail, so that the assembly difficulty is large, and the assembly efficiency is low; at present, the phenomenon that the inner slide rail is pulled out from the middle slide rail and is independently assembled on the drawer type cabinet body is also generated in the field, and then the inner slide rail is inserted into the middle slide rail to synchronously assemble the drawer type cabinet body and the server cabinet in place.
Disclosure of Invention
Aiming at the problems, the invention provides a rear end guiding and limiting structure of a three-section type sliding rail, which can solve the problem that the rear end of the middle sliding rail is easy to be locked with the middle sliding rail and causes the rear end of the middle sliding rail to be stressed and tilted and deformed in the process of installing the inner sliding rail into the middle sliding rail of the existing three-section type sliding rail.
Its technical scheme does, the rear end direction limit structure of three section formula slide rails, the three section slide rails include interior slide rail and outer slide rail, outer slide rail rigid coupling in server rack, interior slide rail and drawer type cabinet body coupling, through middle slide rail sliding connection, its characterized in that between interior slide rail and the outer slide rail: just right concave groove has been seted up respectively on the both sides wall of the tip of the closed direction of middle slide rail, two the embedded stopper that is "worker" font direction that is equipped with of concave groove, the direction stopper is including being "worker" font and connecting into holistic ejector pin, vertical web portion and bottom bar, vertical web portion card in the concave groove, the ejector pin card of direction stopper is in interior slide rail one side, bottom bar card in outer slide rail one side.
Furthermore, the top surface of the ejector rod of the guide limiting block is a plane, and the bottom surface of the ejector rod of the guide limiting block is an arc-shaped surface matched with one side wall of the middle sliding rail facing the inner sliding rail.
Furthermore, the bottom rod of the guide limiting block is a circular rod piece, and the bottom rod of the guide limiting block is clamped between the inner side wall of the outer slide rail and the outer side wall of the middle slide rail.
Furthermore, the width of the vertical web part of the guide limiting block is equal to that of the concave groove.
Furthermore, the guide limiting block is integrally formed by injection molding.
The invention has the beneficial effects that: the two side walls of the end part of the middle sliding rail in the closing direction are respectively provided with an I-shaped guide limiting block, and the guide limiting blocks and the outer sliding rail play a limiting role on the middle sliding rail at the rear end, so that the rear end of the middle sliding rail is effectively prevented from being warped and deformed; in addition, the guide limiting block also effectively limits the bead seat arranged between the inner slide rail and the middle slide rail.

Detailed Description
Referring to fig. 1, the rear end of the three-section sliding rail is guided to the limiting structure, the three-section sliding rail includes an inner sliding rail and an outer sliding rail 10, the outer sliding rail 10 is fixedly connected to the server cabinet, the inner sliding rail is connected to the drawer type cabinet body, and the inner sliding rail is slidably connected to the outer sliding rail 10 through a middle sliding rail 20; just opposite concave grooves 21 are respectively formed in two side walls of the end part of the middle sliding rail 20 in the closing direction, two guide limiting blocks 30 in the shape of an 'I' are respectively embedded in the two concave grooves 21, each guide limiting block 30 comprises an ejector rod 31, a vertical web part 32 and a bottom rod 33, the ejector rods 31 of the guide limiting blocks 30 are clamped in the concave grooves 21, and the ejector rods 31 of the guide limiting blocks 30 are clamped on one side of the inner sliding rail and the bottom rods 33 are clamped on one side of the outer sliding rail 10.
Referring to fig. 2 and 3, the top surface of the top rod 31 of the guide limiting block 30 is a plane 311, and the bottom surface is an arc surface 312 matched with the arc wall 23 of one side of the middle slide rail 20 facing the inner slide rail; the plane 311 of the top rod is used for guiding and limiting the inner slide rail, and the front side end surface 313 of the top rod 31 is used for performing effective axial limiting on a ball seat arranged between the inner slide rail and the middle slide rail 20 so as to prevent the ball seat from moving along with the insertion of the inner slide rail;
