Shelf supporting sliding rail

Abstract

A shelf supporting sliding rail comprises a sliding rail body (1); the front surface of the sliding rail body (1) is provided with protruding parts (2) and recessed parts (3) which are distributed in an array in the length direction; the protruding parts (2) and the recessed parts (3) are arranged alternately, and the protruding parts (2) are next to and connected to adjacent recessed parts (3) above same, so as to form locking positions for fitting of shelf mounting fasteners. Thus, the depth of the locking positions in the direction perpendicular to the front surface of the sliding rail body (1) is increased, so as to improve the locking stability and reliability of shelf mounting fasteners on the shelf supporting sliding rail, thus improving the bearing capacity.

Description

A shelf support slide rail Technical Field

[0001] The utility model belongs to the technical field of refrigerators and shelves, and particularly relates to a shelf support slide rail. Background Art

[0002] Currently, freezers and shelves on the market are often equipped with multiple shelves to accommodate more merchandise. To adjust the shelf positions during use, shelf rail mounting devices are used to secure the shelves. These shelf rail mounting devices include rails and shelf mounting buckles slidably mounted on the rails. However, the shelf mounting buckles of these shelf rail mounting devices lock by latching onto bumps on the rails. Due to space constraints, the height of the bumps is very limited, leaving fewer locations for the shelf mounting buckles to latch onto the bumps, making them prone to slipping and making their locking capabilities unstable and unreliable. Utility Model Content

[0003] In order to solve the above problems existing in the prior art, the utility model provides a shelf support slide rail.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] Through the above solution, the present invention can increase the depth of the locking position in the direction perpendicular to the front surface of the slide rail body 1, thereby improving the stability and reliability of the shelf mounting buckle locking on the shelf support slide rail, and further improving the load-bearing capacity.

[0007] Furthermore, the protrusion is a protruding deformation portion formed on the front surface by punching from the back surface of the slide rail body, and the recess is a rearward recessed deformation portion punched from the front surface of the slide rail body.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] Referring to Figures 1-6, a shelf support rail described in an embodiment of the present invention includes a rail body 1. The front surface of the rail body 1 is provided with raised portions 2 and recessed portions 3 distributed in an array along the length direction. The raised portions 2 and recessed portions 3 are preferably arranged in the middle position of the front surface of the rail body 1. The raised portions 2 and recessed portions 3 are spaced apart from each other, and the raised portion 2 is closely connected to the recessed portion 3 adjacent thereto, forming a locking position for the shelf mounting buckle to be clamped. In this way, the depth of the locking position in the direction perpendicular to the front surface of the rail body 1 can be increased, and the effective locking length of the locking portion 8 of the shelf mounting buckle can be enhanced (as shown in Figure 4), thereby improving the stability and reliability of the shelf mounting buckle locking on the shelf support rail, thereby improving the load-bearing capacity.

[0025] In one possible implementation, the raised portion 2 of the present invention is a convex deformation formed on the front surface of the slide rail body 1 by punching from the back, and the recessed portion 3 is a rearwardly recessed deformation formed by punching from the front surface of the slide rail body 1. The slide rail body 1 is preferably made of an aluminum bar or aluminum alloy bar, and the upper end surface of the raised portion 2 and the lower end surface of the recessed portion 3 are coplanar. This shelf-supported slide rail is simple and easy to manufacture and process at a low cost, making it suitable for mass production and widespread application.

[0026] As shown in Figures 2, 3, 5 and 6, the back of the slide rail body 1 is provided with a convex edge 5 arranged along the length direction, and the convex edge 5 can improve the strength of the slide rail body 1; the top surface of the raised deformation portion formed by the recessed portion 3 on the back of the slide rail body 1 is flush with or lower than the convex edge 5, and the depth of the locking position is maximized without affecting the installation of the slide rail.

[0027] In one possible implementation, as shown in Figures 1, 3, 4, 5, and 6, a mounting hole 7 is provided on the recessed portion 3 corresponding to the slide rail body 1, and the slide rail body 1 is fixed to the inner wall of the freezer or the shelf by means of locking members such as screws passing through the mounting hole 7. Compared with existing slide rails, the locking members can be prevented from interfering with the sliding of the shelf mounting buckles, and the installation accuracy requirements of the locking members can be reduced, thereby reducing the difficulty of assembly. There is no need to specially make room on the front surface of the slide rail body to set up the mounting hole, thereby increasing the number of adjustment levels of the slide rail and making the adjustment of the shelf more flexible.

[0028] In one possible implementation, as shown in Figures 1-6, all adjacent protrusions 2 and recesses 3 of the slide rail are closely connected, and the connection is provided with an opening 6. The opening 6 improves the deformation capacity when punching the protrusions 2 and recesses 3.

[0029] In one possible implementation, as shown in Figures 2, 3, 5, and 6, the left and right ends of the slide rail body 1 are provided with forward-protruding sliding clamping edges 4 arranged along the length direction. The sliding clamping edges 4 are L-shaped and are used to provide the shelf mounting buckles for sliding assembly on the slide rail body 1.

[0030] In addition, the cross-section of the raised portion 2 of the shelf support slide rail of the present invention can be trapezoidal (as shown in Figures 1-3), circular arc-shaped (as shown in Figure 5), or pointed (as shown in Figure 6), and the recessed portion 3 is a trapezoidal recess (as shown in Figures 1-3), circular arc-shaped recess (as shown in Figure 5), or pointed (as shown in Figure 6), and the shape of the raised portion 2 forming the locking position is the same as the shape of the recessed portion 3. Of course, the cross-section of the raised portion 2 can also be a variety of trapezoidal, circular arc-shaped, and pointed, and the recessed portion 3 can be a variety of trapezoidal recess, circular arc-shaped recess, and pointed, and the shape of the raised portion 2 forming the locking position can also be different from the shape of the recessed portion 3.

[0031] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
