As a concrete implementation mode, a plurality of drawer bodies 2 and corresponding mounting sliding assemblies thereof can be arranged in one drawer outer frame 1. In order to facilitate opening and closing, a handle can be arranged on each drawer body 2.

Examples

In order to verify the effectiveness of the scheme of the invention, the clean drawer structure is applied to a clean room in a production area of a medical instrument production factory building, and the clean drawer structure specifically comprises the following steps:

the drawer outer frame 1: the outer frame structure is SS stainless steel, aluminium, metal spraying or other materials, panel beating and welded forming, and the size is customized according to the demand, and interior external surface is level and smooth, does not have exposed structure, easy cleanness.

The drawer body 2: drawer body 2 is SS stainless steel, aluminium, metal coating or other materials, panel beating and welded forming, and the size is customized according to the demand, and interior external surface is level and smooth, does not have exposed structure, easy cleanness.

Side auxiliary limiting block 3: the side auxiliary limiting block is made of plastic materials such as PA, PP, PE, PC, PVC, PMMA, PO, POE, PVP, PU and the like, and is arranged on the inner side of the outer frame of the drawer and corresponds to the position parallel to the lower part of the drawer after the strip is formed.

Lower main limiting slide block 4: lower main spacing slider is plastics materials such as PA, PP, PE, PC, PVC, PMMA, PO, POE, PVP, PU, installs corresponding drawer bracket rail position department in both sides under the drawer after the strip shaping for slide with drawer bracket rail contact.

Drawer-bracket rail 5: the drawer bracket rails are made of SS stainless steel, aluminum, metal spraying or other materials, and are welded and installed on two sides of the outer frame of the drawer after being formed and used for supporting the drawer structure and matching with the sliding motion. The drawer bracket rail is provided with a limiting groove corresponding to the sliding displacement position of the drawer, and the sliding position of the drawer is referred to the condition that the drawer moves to a non-falling state under the condition of no limiting.

Sliding the limit bolt 6: the sliding limiting bolt is made of SS stainless steel, aluminum, metal spraying or other materials, penetrates through a limiting groove of the drawer bracket track during installation, is installed on the lower main limiting slide block and is used for limiting the sliding position of the drawer.

Slider fixing bolt 7: the sliding block fixing bolt is made of SS stainless steel, aluminum, metal spraying or other materials and is used for fixing the lower main limiting sliding block on the drawer bottom plate.

The lower cover plate 8: the lower cover plate is made of SS stainless steel, aluminum, metal spraying or other materials and is used for a mounting hole at the bottom of the outer frame of the drawer.

Cover plate locking bolt 9: the lower cover plate locking bolt is made of SS stainless steel, aluminum, metal spraying or other materials and is used for fixing the lower cover plate on the outer frame of the drawer.

The drawer body 2 is installed on the drawer outer frame 1 on the drawer bracket rail 5 through an installation component (a lower main limit slide block 4, a slide block fixing bolt 7, a sliding limit bolt 6 and the like). A lower main limiting slide block 4 arranged on the drawer, a side auxiliary limiting slide block 3 arranged on the outer frame of the drawer, a sliding limiting bolt 6 and the like form a drawer sliding assembly. When the drawer is pulled and pulled, the combined structure of the main limiting slide block 4 and the sliding limiting bolt 6 arranged below the main limiting slide block at the lower part of the drawer moves along the limiting groove track of the sliding bolt on the drawer bracket track 5 within the allowable range of the sliding limiting bolt. The auxiliary limiting slide blocks 3 on the two sides limit the offset space on the two sides when the drawer acts, so that the sliding track of the drawer is ensured as much as possible, and the friction collision between the sliding limiting bolt and the limiting groove on the drawer bracket track is avoided as much as possible. Experiments prove that the drawer structure is convenient to move, is made of wear-resistant materials, and can avoid dust generation.

Finally, it should be noted that: although the present invention has been described in detail, those of ordinary skill in the art will understand that: the technical solution can still be modified, or some or all of the technical features can be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
