The application belongs to the technical field of shelf installation and fixing, and particularly relates to a shelf supporting apparatus with a supporting seat having a self-locking function.
A shelf, as a main component of a freezer and a goods shelf, is configured to hold commodities and goods. However, the shelf of the existing freezer and goods shelf has a fixed and non-adjustable position, which limits the placed commodities and goods, and is extremely inconvenient to use. Therefore, an adjustable supporting apparatus for the shelf has appeared on the market. The adjustable supporting apparatus includes a slide rail and the supporting seat, the supporting seat being slidably and adjustably installed on the slide rail, and being connected to the slide rail through a locking clamping part arranged on the supporting seat to achieve locking. However, the applicant found that: loosening is easily caused after the locking clamping part and the slide rail of these existing adjustable supporting apparatuses are connected in a locked manner, resulting in poor reliability. For example, during the process of placing the commodities and goods on the shelf, due to the vibration of the shelf, the locking clamping part and the slide rail are prone to loosening, resulting in tilting or even dropping of the shelf. As a result, some manufacturers have added a metal pin to the supporting seat, that is, after the supporting seat is adjusted, and the locking clamping part and the slide rail are connected in a locked manner, the metal pin transversely passes through the supporting seat, so that the metal pin is tightly pressed and attached to the locking clamping part. Although the above problems are solved, the use of the solution not only increases the cost, but also makes the operation become complicated and inconvenient.
In order to solve the above problems in the related art, the application provides a shelf supporting apparatus with a supporting seat having a self-locking function.
In order to solve the above technical problems, the technical solution adopted by the application is as follows.

The side, opposite to the positioning baffle, of the installation position is provided with a locking curved bar. The locking curved bar is able to move up and down and rotatably installed on the supporting seat. When one end of the locking curved bar stretches across the installation position and moves up to be clamped into the limiting hole, locking is achieved. When one end of the locking curved bar moves down and moves out of the limiting hole, unlocking is achieved.
Further, an upper end of the supporting seat is provided with the shelf installation position. The side, close to the slide rail, of the installation position is provided with the positioning baffle. The positioning baffle is provided with a protruding limit stop block and two protruding limit strips. The two protruding limit strips are separated in parallel and upper ends thereof extend to the protruding limit stop block to form a curved bar anti-disengagement locking groove. The side, opposite to the positioning baffle, of the installation position is provided with the locking curved bar. The locking curved bar is able to move up and down and rotatably installed on the supporting seat. When one end of the locking curved bar stretches across the installation position and moves up to be clamped into the curved bar anti-disengagement locking groove, or is close to or reaches the protruding limit stop block, one end of the locking curved bar abuts against a bottom surface of the curved bar anti-disengagement locking groove to achieve locking. When one end of the locking curved bar moves down and moves out of the curved bar anti-disengagement locking groove, unlocking is achieved.
Further, one end, located in the curved bar anti-disengagement locking groove, of the protruding limit stop block is provided with a bayonet, the two protruding limit strips are respectively located on left and right sides of the bayonet, and the upper ends of the two protruding limit strips are respectively connected to the protruding limit stop block abutting against the left and right sides of the bayonet. When the locking curved bar moves up to be locked, the end of the locking curved bar is clamped into the bayonet.
Further, the protruding limit stop block is an arc protruding block, and is provided with a downward inclined surface, configured to guide a chassis of a shelf into the shelf installation position arranged on the upper end of the supporting seat.
Further, a front surface of the supporting seat is provided with a cavity communicating with a back surface, one end, located in the cavity, of the locking curved bar is provided with an operating part, and the operating part is circular.
The application has the following beneficial effects.
In the application, the first buckle is connected to the supporting seat in a buckled manner when the locking clamping part is connected to the slide rail to achieve locking, so that self-locking is achieved, loosening generated after the locking clamping part and the slide rail are connected in a locked manner is effectively avoided, the locking reliability of the supporting seat on the slide rail is further enhanced, and the use safety is higher.
