The utility model discloses a set the inner rail to the M structure, strengthened the inner rail to the elastic deformation ability of both sides in the slip in-process, keep work in the silence environment, have energy-concerving and environment-protective characteristics.
Description
Technical Field
The utility model relates to a steel ball slide rail especially relates to a lift silence slide rail.
Background
The slide rail is usually used to support a drawer or a server chassis (chassis). Along with the development of cloud science and technology, electronic server equipment is also widely adopted by enterprise users, and the application of slide rails is more and more.
The existing slide rail has the advantages that certain pressure is generated between the inner rail and the bead groove in the sliding process, so that noise is easily generated during sliding, and the use comfort is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a lift silence slide rail, noiselessness during the slip uses the travelling comfort good to long service life.
In order to achieve the above object, the embodiment of the present invention adopts the following technical solutions:
the embodiment of the utility model provides a lift silence slide rail, including setting up in the outer rail and along the gliding pearl groove of outer rail, setting in the pearl groove and along the gliding inner rail of pearl groove, the inner rail includes roof and the relative riser that sets up in the roof both sides, M type structure is constituteed to riser and roof, the junction of riser and roof is arc transitional coupling, the roof is the interior concave arc shaped plate, and be provided with downward convex arch on the roof, pearl groove top is provided with the boss to protruding spacing.
Positioning holes for mounting the balls are formed in the two sides of the ball groove;
one side of the vertical plate, which is positioned on the ball, is provided with an inward concave arc surface matched with the ball.
Wherein, the terminal surface of one end of boss is parallel and level with the terminal surface in pearl groove mutually.
Wherein the width of the boss is consistent with the width of the protrusion.
Compared with the prior art, the embodiment of the utility model provides a following beneficial effect has: when using, design into M type structure with the inner rail, increase the horizontal tension of inner rail, improve the silence operation effect, simultaneously, utilize the arch on the inner rail to cooperate with the boss on the pearl groove, push away the pearl groove to the bottommost all the time among the slip process, guarantee the effective sliding distance of slide rail.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is the three-dimensional structure schematic diagram of the lifting silent slide rail of the present invention.
Fig. 2 is a schematic perspective view of the inner rail.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
Referring to fig. 1-2, an embodiment of the present invention provides a lifting silent sliding rail, including a bead groove 2 disposed in an outer rail 1 and sliding along the outer rail 1, and an inner rail 3 disposed in the bead groove 2 and sliding along the bead groove 2, wherein the inner rail 3 includes a top plate 31 and vertical plates 32 disposed at two sides of the top plate 31, the vertical plates 31 and the top plate 32 form an M-shaped structure, a connection portion between the vertical plates 32 and the top plate 31 is an arc-shaped transition connection, the top plate 32 is an inner concave arc-shaped plate, and the inner rail is designed into an M-shaped structure, so as to increase a transverse tension when the inner rail 3 slides in the bead groove 2, thereby increasing a close fit degree of the inner rail 3, the bead groove 2, and the outer cabinet 1, ensuring that the inner rail 3 slides without noise, improving working comfort, saving energy, and protecting environment;
the top plate 31 is provided with a protrusion 311 protruding downwards, the top of the bead groove 2 is provided with a boss 21 limiting the protrusion 311, one end face of the boss 21 is flush with the end face of the bead groove 2, and the width of the boss 21 is consistent with that of the protrusion 321. When the sliding rail is used, the boss 21 is pushed through the protrusion 311, so that the ball groove 2 can be always pushed to the bottom end, and the sliding distance of the sliding rail is ensured to be unchanged.
Further, the both sides of ball groove 2 all are provided with the locating hole of installation ball 4, and one side that riser 31 is located the ball is provided with the interior concave arc face 312 with ball matched with, increases the power of roll slip, reduces the frictional force of rubbing with the ball, further promotes the effect of falling the sound.
In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
