Description

Technical Field

[0001] The present invention belongs to the technical field of commercial facilities, and particularly relates to a matching structure between a shelf board and a support arm of a shelf. Background Art

[0002] The shelf board of the aforesaid shelf is the shelf's shelf board for carrying goods; the aforesaid support arm is for placing the shelf board and cooperating with the shelf board and the upright column. As is known in the industry, shelves are widely used in self-service malls, supermarkets, express delivery industries, warehouses and storerooms, etc., and there is no shortage of technical information about shelves in the publicly disclosed Chinese patent documents. For example, the authorized publication numbers are CN2712188Y (shelf), CN201384282Y (shelf), CN202287153U (shelf upright column structure), CN202287359U (shelf upright column), CN202287361U (shelf), CN202302692U (matching structure between the bottom beam and the upright column of the shelf), CN104305735A (shelf), CN105640094A (assembled shelf) and CN103251241B (assembled shelf), etc.

[0003] By reading the patent documents not limited to the above examples and combining the professional common sense in this field, it can be known that: in order to avoid the deformation (also called "deflection") of the shelf board after loading, generally, reinforcing rib strips, that is, reinforcing rib plates, are arranged at the bottom of the shelf board of the shelf. Specifically: the reinforcing rib strips with a generally trapezoidal cross-sectional shape folded by a folding machine are riveted to the shelf board with rivets. The shelf board of this structure has a significantly improved load-bearing capacity due to the addition of the reinforcing rib strips riveted to it, and can meet long-term use without generating deflection within the reasonable load range.

[0004] The patent of "shelf board structure" recommended by CN110279241A points out and remedies many technical problems caused by fixing the reinforcing rib to the shelf board by means such as riveting or spot welding, and objectively realizes the five aspects of technical effects summarized in the technical effect column of its specification. However, when the shelf is in use, the above-mentioned patents including the aforesaid CN10279241A have the general problem that the shelf board and the support arm are not sufficiently combined to achieve the good combination effect expected by the industry. Specifically speaking, due to disadvantages such as the shelf board slipping relative to the support arm, shaking up and down and / or moving horizontally, on the one hand, there is a risk to the safety of on-site personnel, and on the other hand, when the shelf board moves away from the support of the support arm, it will cause the goods to fall together with the shelf board and damage the goods; on the other hand, it affects the mutual restraint between the shelf board and the support arm and makes the structure appear loose. In view of the above, it is necessary to make reasonable improvements, and the technical solution to be introduced below is generated under this background. Summary of the Invention
