Detailed Description

The present invention will be further described with reference to the following examples, which are not intended to limit the scope of the present invention, but are intended to be covered by the appended claims in any way.

Referring to fig. 1-4, the utility model discloses a walk pearl slide rail convenient to installation, including upper rail 1 and lower rail 2, upper rail 1 walks pearl and lower rail 2 sliding connection through sliding. The utility model discloses a walk pearl slide rail still includes two installation ears 3. Specifically, a first bending portion 7 and a second bending portion 8 are arranged above the mounting ears 3, the first bending portion 7 is perpendicular to the mounting ears 3 and extends outwards, and the second bending portion 8 is perpendicular to the mounting ears 3 and extends inwards. I.e. the first 7 and second 8 bends are arranged at 180. Two long waist-shaped mounting holes 9 are formed in the second bending portion 8 and used for mounting screws so as to fix the sliding rail on the object placing plate. Because the bending part extending outwards is only arranged on the existing slide rail hanging lug, in the using process of the slide rail, the bending part is easy to deform to cause the outward upwarping of the slide rail. This condition eventually causes the space between the slide rails on both sides of the placement board to gradually increase, and the upper rail 1 is easily pulled out from the lower rail 2, resulting in damage to the slide rails. Therefore, the utility model discloses set up the second portion of bending 8 with first portion of bending 7 mutual arrangement, through the second portion of bending 8 and the interact who places the board reduce the deformation degree of first portion of bending 7, can the effectual risk that reduces the slide rail and damage.

Preferably, the first bending portion 7 is provided with a plurality of reinforcing ribs extending to the second bending portion 8, so as to increase the rigidity of the bending portion and further reduce the deformation degree of the first bending portion 7.

Preferably, a positioning link 10 is provided between the first bending portion and the mounting ear 3. The degree of deformation of the first bending part 7 can be further reduced by positioning the positioning connecting rod 10 between the first bending part 7 and the mounting lug 3.

Be equipped with two installation archs 4 with installation ear 3 one-to-one on the outer wall of upper rail 1, all set up the through-hole of seting up along slide rail sliding direction in every installation arch 4, and the through-hole runs through installation arch 4. Wherein the mounting protrusion 4 is formed by directly pressing the bottom surface of the upper rail 1, and a through hole penetrating the mounting protrusion 4 is formed between the mounting protrusion 4 and the upper rail. The mounting lug 3 is provided with a raised inserting sheet 5, and the inserting sheet 5 is inserted in the through hole; the inserting sheet 5 is provided with a positioning hole, the outer side of the mounting protrusion 4 is provided with a rebounding device 6, and one end of the rebounding device 6 penetrates through the mounting protrusion 4 and is movably inserted into the positioning hole. After the insertion sheet 5 is inserted into the through hole, the installation of the slide rail is realized by positioning the installation bulge 4 through the insertion sheet 5; then the rebounding device 6 is started, so that the end part of the rebounding device 6 is inserted into the positioning hole, the positioning of the slide rail is realized, and the phenomenon that the slide rail slides relative to the mounting lug 3 in the use process is avoided.

Specifically, the rebounding device 6 comprises a cylinder 601, an upper key 602, a lower key 603 and a cylinder 604 which are connected in sequence are installed in the cylinder 601, the upper key 602 penetrates through one end of the cylinder 601, and the cylinder 604 penetrates through the other end of the cylinder 601 and is movably inserted into the positioning hole. A step 605 is arranged in the cylinder 601, four sliding grooves 606 are arranged on the step 605, and a positioning groove 607 is arranged in each two adjacent sliding grooves 606. The length of the sliding slot 606 is greater than that of the positioning slot 607. Four first sliding protrusions 608 are arranged on the outer side of the upper key 602, and the first sliding protrusions 608 are in one-to-one sliding connection with the sliding grooves 606. Four second sliding protrusions 609 are arranged on the outer side of the lower button 603, and the second sliding protrusions 609 are inserted into the sliding groove 606 or the positioning groove 607. I.e. the second sliding projections 609 are positioned differently when the rebounding means 6 are in different states. Specifically, when the rebounding device 6 acts, the cylinder 604 is inserted into the positioning hole, and the second sliding protrusion 609 is located in the positioning groove 607; when the rebounding device 6 is reset and the column 604 leaves the positioning hole, the second sliding protrusion 609 is located in the sliding groove 606. The bottom of the upper key 602 is provided with continuously arranged helical teeth, a slope is arranged above the second sliding protrusion 609, and the tooth tips of the helical teeth are in contact with the slope. The column 604 is provided with a limiting protrusion 610, and a spring 611 is sleeved on the column 604 between the limiting protrusion 610 and the bottom plate of the cylinder 601.

When the rebounding device 6 is in the reset state, the column 604 is separated from the positioning hole, and the first sliding protrusion 608 and the second sliding protrusion 609 are both located in the sliding groove 606. When the upper button 602 lifts the lower button 603, the lower button 603 is pushed out of the sliding slot 606, and the second sliding protrusion 609 of the lower button 603 slides into the step 605 because the tooth tip of the helical tooth contacts with the slope surface. Meanwhile, the column 604 is pushed up by the lower button 603 and inserted into the positioning hole, and the spring 611 contracts. The lower button 603 is rotated by the force of the spring 611 and the rotational force when it slides, and falls into the positioning groove 607, so that the cylinder 604 is pushed into the positioning hole, and the cylinder 604 is positioned. When the post 604 is separated from the pilot hole, the action of the rebounding device 6 is substantially identical to that described above, and is no longer cumbersome.

The column 604 is a metal column, and the end of the column 604 is a hemispherical structure, so that the column 604 can be smoothly guided into the positioning hole.

Preferably, the inner side of the mounting protrusion 4 is provided with a plurality of anti-slip protrusions.

The utility model discloses a theory of operation is: install the lower rail 2 of slide rail on the side of placing the board to place the below of putting the thing board in with installation ear 3, alternate the mounting hole 9 in the first bending portion 7 with the screw, and connect the screw soon on putting the thing board, in order to accomplish the installation of installation ear 3. Then the placing plate is held, the mounting protrusions 4 of the upper rail 1 are aligned with the inserting pieces 5 on the mounting lugs 3, and the placing plate is pushed, so that the inserting pieces 5 are inserted into the mounting protrusions 4. And then the upper key 602 is pressed down to enable the column 604 to be inserted into the positioning hole, so that the operation is simple and convenient, and the installation of the slide rail is convenient.
