Description

Drawer improved structure

The invention belongs to the technical field of drawers, in particular to a drawer improved structure, the user only needs to adjust whether the sliding grooves are arranged on a table or a shelf, whether the height is high and the left and right positions are symmetrical, and whether the angle of each chute is horizontal The drawer body can be installed in each of the chutes, and the utility model has the advantages of simple installation and convenient use.

Generally, some tables, shelves are like computer tables or some simple tables and shelves have no drawer design, and the table has no drawers, so that the table is full of debris, taking up space available on the table, and the desktop is miscellaneous. Things can easily lead to the inability to find items to use. In order to save money and protect the environment, some users will install drawers under these tables and shelves. When drawers are added, slides are added to the table, shelves and drawers so that the drawers can be placed under the table and under the shelves.

However, when adding slide rails to tables, shelves and drawers, it is necessary to accurately calculate whether the height of the table, the shelf and the drawer installation rails and the left and right positions are symmetrical and angled. Otherwise, the drawers may be asymmetrical or uneven. It is a problem that the drawer cannot be closed, and the slide rails of the fashion drawer are too weak, which may cause the slide rail to fail to support the weight of the drawer and be damaged.

In view of the above-mentioned deficiencies, the inventors have created a method for adding a drawer. Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure with more ideal and practicality is really eagerly awaited by consumers, and it is also necessary for relevant industry players to work hard to develop The goal and direction of the breakthrough. In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the inventor has finally obtained the practical invention.

When adding slide rails to tables, shelves and drawers, it is necessary to accurately calculate the height of the table, the shelves and the drawers, and whether the left and right positions are symmetrical and angled. Otherwise, it is easy to cause the left and right sides of the drawer to be asymmetrical, uneven or drawers. Problems such as inability to close, and the rails of the fashion drawer are too fragile, which can cause the rails to fail to support the weight of the drawer.

A drawer improved structure includes: a plurality of sliding slots, each of which is provided with an extension plate, each of the extension plates is provided with a concave wheel with a wheel inwardly concave; a drawer body, the drawer body is opposite to the two Each of the sides has a frame, and each of the frames is provided with a plurality of accommodating recesses, and the cams of the plurality of wheels are disposed in the accommodating recesses, and the shapes of the cams are matched with the shapes of the recesses of the recessed wheels. And a concave arc of each of the concave wheels is matched with a lower edge of the plurality of frames; wherein a rear end of each of the sliding slots is provided with a positioning structure for restricting a position at which the drawer body moves; wherein each of the sliding grooves has a C-shaped cross section Wherein, a cam seat is disposed between each of the frames and each of the cams, and each of the cam seats abuts each of the recessed wheels when each of the frames is extended.

First, the user first installs each of the chutes on a table or shelf with pre-installed drawers. And then tilting the drawer body at an appropriate angle so that each of the cams is slidably disposed in each of the slots by the open space of each of the extension plates, and each frame is located In each of the sliding slots, each of the concave wheels and each of the cams are slidably disposed in each of the sliding slots; by the above structure, the user only needs to adjust the height and the left and right of each of the sliding slots mounted on the table or the shelf. If the position is symmetrical, and the angle of each of the chutes is horizontal, the drawer body can be installed in each of the chutes. Since the frames on both sides of the drawer body are already parallel symmetrical, the cams can be directly loaded into the sliding slots after being installed, without being loaded into the drawer as in the prior art. The position of the slide rail on the main body is high and low, and whether there is symmetry between the left and right sides and whether the slide rail is inclined, the installation is simple and the use is convenient. Moreover, since each of the frames of the drawer body itself can support the weight of the drawer body, there is no problem that the slide rails installed on the drawer body are too weak.

The above-mentioned objects, structures and features of the present invention will be described in detail with reference to the preferred embodiments of the present invention. .

First, the preferred embodiments of the present invention are shown in Figures 1 through 6, but the embodiments are for illustrative purposes only and are not limited by the structure.

The improved structure of the drawer, as shown in FIG. 2, includes a plurality of sliding slots 10, and each of the sliding slots 10 is provided with an extension plate 11 at each end thereof, and each of the extension plates 11 is provided with a concave inner side of the wheel. The wheel body 12 has a frame 21 on each of the opposite sides of the drawer body 20, and each of the frames 21 is provided with a plurality of receiving recesses 22, and the cams 23 of the plurality of wheels are outwardly convex. In the groove 22, the shape of each of the cams 23 is matched with the concave shape of each of the concave wheels 12, and one concave arc 15 of each of the concave wheels 12 and the lower edge 24 of the plurality of frames are matched with each other; Each of the two sides of the frame 21 is provided with a receiving recess 22; wherein a rear end of each of the sliding slots 10 is provided with a positioning structure 13 , and each of the positioning structures 13 is fixed to the other end of the concave wheel 12 . The sliding slot 10 limits the displacement of each of the cams 23 of the drawer body 20 between each of the recessed wheels 12 and each of the positioning structures 13 in each of the sliding slots 10.

Each of the chutes 10 has a C-shaped cross section; wherein each of the frames 21 and each of the cams 23 is provided with a cam seat 14 , and when each of the frames 21 stretches out each of the chutes 10, The cam seat 14 abuts against each of the recessed wheels 12.

As shown in Figures 1, 3 and 4, first, the user first installs each of the chutes 10 on a table or shelf pre-installed with drawers, and then tilts the drawer body 20 at an appropriate angle to allow each of the cams 23 to By the open space of each of the extension plates 11, and matching the respective concave wheels 12 The frame 21 is slidably disposed in each of the sliding slots 10, and each of the frames 21 is disposed in each of the sliding slots 10, and is slidably disposed in each of the sliding slots 10 by using the concave rollers 12 and the cams 23; In the above configuration, the user only needs to adjust whether the height and the left and right positions of the sliding slot 10 are mounted on the table or the shelf are symmetrical, and whether the angle of each of the sliding slots 10 is horizontal, the drawer body 20 can be mounted on each of the drawers 20 Inside the chute 10. Since the frames 21 on both sides of the drawer body 20 are already parallel symmetrical, the cams 23 can be directly loaded into the sliding slots 10 without having to be measured as in the prior art. The position of the slide rail mounted on the drawer body 20 is high and low, and whether there is symmetry between the left and right sides and whether the slide rail is inclined, the installation is simple and the use is convenient. Moreover, since each of the frames 21 of the drawer body 20 can support the weight of the drawer body 20, there is no problem that the slide rails installed on the drawer body 20 are too weak, and due to the concave The concave arc 15 of the wheel 12 and the lower edge 24 of each of the frames are matched to each other to achieve a stable displacement of the internal structure.
