Description

Technical Field

[0001] The utility model relates to the technical field of drawers, in particular to a finger-pinch-proof drawer. Background Art

[0002] A drawer is a pull-out box-shaped component attached to furniture such as tables and cabinets. It refers to a box used to store things in furniture such as tables and cabinets. It can be pulled out and pushed in to hold things. It is very common in daily life.

[0003] When optimizing existing anti-pinch drawers, most of them are reflected in the addition of dust strips to ensure the cleanliness of the stored items and facilitate cleaning and replacement. For example, the Chinese utility model patent with application number CN200910199370.1 discloses an anti-pinch drawer. In this device, the drawer can be pushed into and pulled out of the drawer slot from the drawer slot opening on the furniture body. The drawer includes a front baffle, which is characterized in that: the length of the drawer is the same as the length of the drawer slot, the height of the drawer box body is equal to the width of the front baffle, the width of the drawer box body is equal to the length of the front baffle, and the drawer Anti-pinch gaps are left between the top, left and right sides of the drawer groove, and dust strips are provided on the groove top, side walls and groove openings of the drawer groove. The dust strips are connected to the drawer front baffle at the relative position and are fully pushed into the drawer groove. The front side surfaces of the drawer, the front baffle, the dust strips and the furniture body are in the same vertical plane. No matter where the user puts their fingers when pushing and pulling the drawer, they will not be easily pinched. The dust strips can ensure the cleanliness of the stored items and are easy to clean and replace. The device has a simple structure, is easy to process and has obvious effects, which is conducive to its popularization in daily life.

[0004] Although the above-mentioned anti-pinch drawers have certain advantages in adding dust-proof strips to ensure the cleanliness of stored items and facilitate cleaning and replacement, they still have certain disadvantages: due to the stacking structure of multi-layer drawers, different items are placed inside the drawers. When people are looking for things, they may pull out drawers on different layers. The stacked structure can easily cause people to be pinched. Utility Model Content

[0027] See also Figure 1-2 A finger-prevention drawer includes a drawer 1, a handle 2, an outer frame 3, a limit track 4, a rotating handle 5, a slide rail 6, a finger-prevention structure 7, and a strip board 8. The handle 2 is welded to the outer front end surface of the drawer 1. The limit track 4 and the outer frame 3 are integrated and are arranged through the side end surface. The rotating handle 5 passes through the inside of the limit track 4. The slide rail 6 is fixed on the inner wall surface of the outer frame 3. The strip board 8 is an integrated structure with the drawer 1 and is located on the left and right end surfaces. The finger-prevention structure 7 is connected to the rear end of the strip board 8. The base q1 is fixedly mounted at the inner side end of the slide rail 6 and is in coordination with the drawer 1. The upper end of the movable body q4 is connected to the side end of the strip 8. The movable body q4 moves intermittently on the left and right sides of the drawer 1. The disc q21 moves intermittently on the side of the vertical frame q3. The connecting block q22 slides with the movable body q4. The round rod q23 is embedded in the end of the handle 5. The disc q21 is manually rotated by the operator to drive the connecting block q22 to perform a circular displacement, causing the disc q21 to rotate.

[0028] See also Figure 3-4 , a finger-prevention drawer, the finger-prevention structure 7 includes a base q1, a driving rotator q2, a vertical frame q3 and a movable body q4. The lower end of the vertical frame q3 is welded to the bottom of the base q1. The driving rotator q2 moves on the side of the vertical frame q3. The movable body q4 moves on the side of the driving rotator q2. The lower end of the movable body q4 is hinged to the base q1. The driving rotator q2 includes a disc q21, a connecting block q22 and a round rod q23. The connecting block q22 is installed on the outside of the side end of the disc q21 through the round rod q23. The round rod q23 is arranged perpendicular to the end face of the disc q21, and the round rod q23 passes through the interior of the connecting block q22.

[0029] See also Figure 5 , a finger-prevention drawer, the movable body q4 includes a swing frame q41, a sliding channel q42, a linkage frame q43, a fixed seat q44 and a connecting block q45. The sliding channel q42 and the swing frame q41 are an integrated structure and are arranged through.
