SHELF SUPPORTING SLIDING RAIL

Abstract

The present invention relates to a shelf supporting sliding rail, including a sliding rail body. Protrusions and recessed portions distributed in an array in a length direction are arranged on a front surface of the sliding rail body. The protrusions and the recessed portions are arranged in a spaced manner, and the protrusions are in close connection to the recessed portions adjacent to the protrusions above to form a locking position where a shelf mounting buckle is locked. The depth of the locking position in a direction perpendicular to the front surface of the sliding rail body increases, to improve the locking stability and reliability of the shelf mounting buckle on the shelf supporting sliding rail, and further improve the bearing capacity.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make objectives, technical solutions, and advantages of the prevent invention clearer, the prevent invention will be further described in detail below in combination with drawings and embodiments. It should be understood that the specific embodiments described herein are merely used for explaining the present invention and are not used for limiting the present invention.

[0025] Referring to FIGS. 1-6, a shelf supporting sliding rail provided in an embodiment of the present invention includes a sliding rail body 1, where protrusions 2 and recessed portions 3 distributed in an array in a length direction are arranged on a front surface of the sliding rail body 1, the protrusions 2 and the recessed portions 3 are preferably arranged at the middle position of the front surface of the sliding rail body 1, the protrusions 2 and the recessed portions 3 are arranged in a spaced manner, and the protrusions 2 are in close connection to the recessed portions 3 adjacent to the protrusions above to form a locking position where a shelf mounting buckle is locked. Thus, the depth of the locking position in the direction perpendicular to the front surface of the sliding rail body 1 can be increased, and the effective locking length (as shown in FIG. 4) of the locking portion 8 of the shelf mounting buckle is increased, so that the locking stability and reliability of the shelf mounting buckle on the shelf supporting sliding rail are improved, and therefore, the bearing capacity is improved.

[0026] In a possible implementation mode, each of the protrusions 2 in the present invention is a protruded deformation portion formed on the front surface by punching from a back surface of the sliding rail body 1, and each of the recessed portions 3 is a backward recessed deformation portion by punching from the front surface of the sliding rail body 1; the sliding rail body 1 is preferably an aluminum strip or an aluminum alloy strip, and an upper end surface of each of the protrusions 2 and a lower end surface of each of the recessed portions 3 are located in a same plane. The shelf supporting sliding rail is simple and easy to produce and machine, low in cost, and is favorably produced in batches and popularized and applied.

[0027] As shown in FIGS. 2, 3, 5, and 6, a flange 5 arranged in the length direction is arranged on the back surface of the sliding rail body 1, and the strength of the sliding rail body 1 can be improved through the flange 5; and a top surface of the protruded deformation portion formed by each of the recessed portions 3 on the back surface of the sliding rail body 1 is flush with the flange 5 or lower than the flange 5, so that the depth of the locking position is increased to a maximum extent without affecting mounting of the sliding rail.

[0028] In a possible implementation mode, as shown in FIGS. 1, 3, 4, 5, and 6, a mounting hole 7 is formed in each of the recessed portions 3 corresponding to the sliding rail body 1. The sliding rail body 1 passes through the mounting hole 7 through a locking piece such as a screw and is fixed to an inner wall of an ice locker or a storage rack. Furthermore, compared with an existing sliding rail, sliding of the shelf mounting buckle can be prevented from being interfered with by the locking piece, and the mounting precision requirement on the locking piece can also be reduced, so that the assembly difficulty is reduced. It is not intended to make way on the front surface of the sliding rail body to arrange the mounting hole, so that the adjustable step number of the sliding rail is increased, and the shelf is adjusted more flexibly.

[0029] In a possible implementation mode, as further shown in FIGS. 1-6, all adjacent protrusions 2 and recessed portions 3 of the sliding rail are in close connection, and openings are formed at connections 6. The deformability when the protrusions 2 and the recessed portions 3 are punched is improved through the openings 6.

[0030] In a possible implementation mode, as further shown in FIGS. 2, 3, 5, and 6, forward protruding sliding locking edges 4 arranged in the length direction are arranged at left and right ends of the sliding rail body 1, through which the shelf mounting buckle is slidably assembled on the sliding rail body 1, and the sliding locking edges 4 are L-shaped.

[0031] In addition, a section of each of the protrusions 2 of the shelf supporting sliding rail provided by the present invention can be in a shape of a trapezoid (as shown in FIGS. 1-3) or an arc (as shown in FIG. 5), or a sharp angle (as shown in FIG. 6), each of the recessed portions 3 is a trapezoidal recess (as shown in FIGS. 1-3), an arc-shaped recess (as shown in FIG. 5), or a sharp angle-shaped recess (as shown in FIG. 6), and the shape of each of the protrusions 2 that forms the locking position is the same as the shape of each of the recessed portions 3. Of course, the section of each of the protrusions 2 can be in a shape of more of a trapezoid, an arc, and a sharp angle, each of the recessed portions 3 is more of a trapezoidal recess, an arc-shaped recess, and a sharp angle-shaped recess, and the shape of each of the protrusions 2 that forms the locking position can also be different from the shape of each of the recessed portions 3.

[0032] The above is merely the preferred implementation mode of the present invention. It shall be noted that those of ordinary skill in the art can further make several improvements and embellishments without departing from the principle of the present invention, and these improvements and embellishments shall be regarded as the protection scope of the present invention.
