Description

Improved structure of shelf drawer and slide rail

This creation is about a kind of storage basket, especially about an improved structure of the drawer and slide rail of the storage rack.

According to the commonly known drawer structure of the basket rack, it includes the drawers combined on a rack body. The upper edges of the two side walls extend outward from the upper edges of the two side walls. A hanging ear protrudes, which can be slidably assembled on both sides of the rack body. The combined groups of relative ㄈ-shaped slide rails form a combined structure that can guide the drawer pulling operation.

However, because the ㄈ-shaped slide rails on both sides of the frame body do not have any structure that can limit the hanging ears on both sides of the drawer, it is easy to cause the hanging ears on both sides to separate from the drawer when the drawer is deformed by pulling force. If the sliding group of the ㄈ-shaped slide rail falls off, it causes many inconveniences in use.

In view of the aforementioned problems, the creator has made careful research and development. Therefore, the main purpose of this creation is to provide an improved structure for shelf drawers and sliding rails, by installing a card in the inner edge of the near rear end of the hanging ears on both sides of the drawer. The latches, and the corresponding slide rails are provided with recesses for the positioning of the latches at the front and rear ends of the corresponding slide rails, and the front and rear recesses are used for the latches of the hanging ears to resist the limit to prevent the drawer from opening Or the phenomenon of slipping when folded or falling between the drawer and the slide rail.

In order to achieve the above purpose, this creation provides an improved structure of shelf drawers and sliding rails, which includes at least one drawer with a storage box body and two hanging ears. The two hanging ears are separated from the The left and right sides of the storage box body are extended outwards, and the two hanging ears are provided with a catch bump on the inner edge of the near rear end; at least two sliding rails are set corresponding to the drawers, and the two hanging ears are inserted in between and guided respectively To move, the front and rear ends of each slide rail are respectively provided with recessed inserts for the positioning of the latching protrusions; by this, when the drawer is in the closed state, the latching protrusions of the two hanging ears can be restricted to the slide rails When the drawer is in the open state, the catching convex block of the two hanging ears can be restricted in the concave inlay near the front end of the slide rail when the drawer is in the open state.

In the improved structure of shelf drawer and slide rail disclosed above, the cross-sections of the two slide rails respectively define a ㄈ shape with left and right mirror images, and the upper and lower open sides are respectively recessed at right angles to form a transverse concave shape. Each of the hanging ears extends horizontally outwards and then further upwards, so that the cross-sections of the two hanging ears are respectively a horizontal T-shaped body with left and right mirror images.

In the improved structure of the shelf drawer and slide rails disclosed above, the front and rear recesses of the two slide rails are arranged oppositely on the right-angled edges of the lower recesses, and the front recessed recesses have a gradual progression from front to back. A high forward guide slope, the lower side of the guide slope is provided with a flat abutment part, and the rear end recess has a reverse guide slope that gradually decreases from front to back, and the lower side of the guide slope is also provided with a flat abutment part .

Regarding the technical means used by this creation to achieve the above-mentioned purpose, I will use the following implementation styles and icons to illustrate in detail below, so that Jun Shang will understand and agree with it.

Please refer to Figure 1 to Figure 2 for an improved structure of drawers and sliding rails of the present creation, including:

At least one drawer 10 has a storage box body 11 and two hanging ears 12, the two hanging ears 12 respectively extend outward from the left and right sides of the storage box body 11, and the two hanging ears 12 are provided near the inner edge of the rear end There is a detent protrusion 121. In this embodiment, the two hanging ears 12 of the drawer 10 extend horizontally outward and then further upward, so that the cross-sections of the two hanging ears 12 are respectively a horizontal T-shaped body with left and right mirror images;

At least two sliding rails 2o are set corresponding to the drawer 10, and the two hanging ears 12 are inserted therebetween to guide the movement. The front and rear ends of each sliding rail 20 are respectively provided with two hanging ears 12 to lock the protrusion 121 for positioning. The recessed inserts 23 and 24. In this embodiment, the cross-sections of the two slide rails 20 respectively define a ㄈ shape that is left and right mirror images, and the upper and lower open sides are respectively recessed at right angles 21 and 22 to form a transverse recessed body. The front and rear edge recessed inserts 23 and 24 of the two slide rails 20 are arranged on the horizontal plane 221 of the right-angle folded edge 22 of the lower recess and are arranged oppositely. The front edge recessed insert 23 has a forward guide slope 231 that gradually increases from front to back. , The guide slope 231 is provided with a flat abutment portion 232 at the low side, and the rear edge recess 24 has a reverse guide slope 241 that gradually decreases from front to back, and the guide slope 241 also has a flat counter at its lower side. Arrived at 242.
