Abstract

An inner guide rail for desks and cabinet drawers, especially an inner guide rail for desks or cabinet drawers made of stamped and bent metal plates. When the upper pulley slides to the downward sloping extension of the rear section of the slideway, it can limit the pulley from shaking up and down in the slideway, so as to prevent the drawers from colliding with each other; in addition, due to the change of the position and structure of the stopper, the stopper can be adjusted forward and backward position, to moderately adjust the depth of the drawer panel protruding from the side of the table or cabinet.

Description

Inner rails for desk and cabinet drawers

The utility model relates to an inner guide rail for desk and cabinet drawers, which can prevent the pulleys on the drawers from shaking up and down in the slideway, so as to prevent the drawers from colliding with each other; and has a stopper that can be adjusted back and forth.

Commonly used metal desks and cabinets are widely used because they are easy to manufacture, low in cost, sturdy and practical. , welded and bent; as shown in Figure 1, a general metal desk generally includes two parts: a desk body 10 and a drawer 20, wherein the desk body 10 is divided into a table top 11 and a table body 12 (that is, the receiving drawer part), The receiving drawer space 13 of the table body 12 is bent by a metal plate into a space with five sides closed and one side open, and four side bars 15 are respectively welded to the four corners 14 of the space, so that the four corners of the angular column shape are reinforced; As shown in Figure 2, on the inner side of the four corners of the two adjacent sides of the opening of the table body 12, the opposite inner guide rails 30 are respectively welded. Road 31, the rear section of the lower flange 32 of the slideway 31 expands downwards to form a larger slideway opening 321, and the front section of the slideway 31 expands downwards and turns up to be L-shaped, and the front section is larger than the front section. Punch and fold and turn up the clips 311, 312 to clamp and fix a soft (rubber, plastic) stopper 40, and a guide wheel 50 is set behind the stopper 40; The functions are respectively: the downward expansion opening 321 of the rear section of the slideway is to make the pulley 21 on the drawer 20 slide to the downward expansion opening 321, so that the drawer 20 can be positioned due to the downward component force of the inclined surface without Make the drawer slide out; in addition, the stopper at the front end of the slideway is to set the drawer panel 22 when the drawer is closed, and the convex position between it and the side table; and the guide wheel 50 is used to guide the pulley 21 on the drawer 20 and the outer guide rail 24; in summary, the commonly used inner guide rail 30, it is not difficult to find that it has the following disadvantages:

(A) Schematic diagrams of commonly used inner guide rails and drawers as shown in Figures 3A, 3B, and 3C. When the pulley 21 on the drawer slides to the position shown in Figure 3A, the downward component force of the inclined surface makes the pulley 21 slides to the position shown in Figure 3B, but because the slideway space at this position is much larger than the diameter of the pulley, when the table is moved or subjected to other external forces of up and down movements, the drawer is as shown in Figure 3C. The tail of the drawer is upturned, causing the panel to shake up and down, and collide with other drawers, causing damage to the surface at the collision point (such as paint peeling off).

(B) As shown in Figure 2, the stopper of the commonly used inner guide rail is a soft rubber (or plastic) long block, which has the effect of setting the position of the drawer panel and buffering the inward closing force of the drawer; Long, that is, when the drawer panel is too protruding, the overly long stopper part can be cut off, but when the drawer panel is too sunken, it cannot be adjusted, so when the stopper is too short, it is impossible to avoid the drawer sunken shortcoming.

In view of the above problems, the main purpose of this utility model is to provide an inner guide rail. Under the principle of not affecting its original downward slanting extension and guiding the pulley slanting down, the rear section of the slideway can prevent the pulley from falling on the slanting surface. The lower section of the slideway shakes up and down; the upper edge of the slideway and the lower section of the lower edge are inclined parallel to each other, which can limit the up and down movement of the pulley, that is, avoid the mutual collision of the drawer panels.

The secondary purpose of this utility model is to provide a stopper device with adjustable front and rear positions, which is located at the front end of the side wall of the inner guide rail. Due to the flexibility of the metal feature, the stopper device can be tilted back and forth, and Adjust it to the most appropriate position.

In order to achieve the above purpose, the utility model provides an inner guide rail for desks and cabinet drawers, which is formed by stamping and bending a rectangular metal plate, and mainly includes horizontal slides in the front and middle sections of the inner guide rail and a slightly downward slope in the rear section. The slideway; the horizontal slideway in the middle section is a U-shaped opening, and its upper and lower guards are parallel to each other, and the appropriate position of the rear section is also a slightly inclined downward track parallel to each other to prevent the pulley from shaking up and down; The front section of the horizontal slideway expands the distance between the upper and lower flanges respectively, and the upper edge tends to be turned up to be on the same plane as the side wall, and is folded at the front end of the inner guide rail to connect with the side wall and the lower flange of the slideway respectively. A vertical baffle, and a soft stopper is fixed on the baffle.

Please refer to the inner guide rail for desks and cabinet drawers of the present utility model shown in Fig. 4, which is an inner guide rail 60 made of a rectangular metal plate through stamping and bending, mainly including the front section 61 of the inner guide rail, the horizontal slideway 62 of the middle section and the rear Slightly downward-sloping slideway 63, wherein the horizontal slideway 62 of the middle section is a track with an outward opening and the upper and lower guards 621, 622 are parallel to each other, and the front section of the horizontal slideway 62 makes the upper and lower guards respectively Expand the spacing, and the upper edge tends to turn up to be on the same plane as the side wall 64, and at the front end of the inner guide rail, turn over a blocking piece 611 perpendicular to the side wall 64 and the lower guard edge 622 of the slideway respectively, And a soft stopper 70 is fixedly set on the catch piece 611, and a guide wheel 80 is set on the side wall next to the catch piece 611; in addition, the rear section of the horizontal slideway 62 is a slightly downward slide 63, that is, its upper and lower guards 631, 632 are parallel and inclined tracks; as mentioned above, the inner guide rail 60, wherein the slightly downward-sloping slideway 63 of the rear section can make the pulley 21 on the drawer (as shown in Figure 5A, 5B, 5C) Shown) backward and slightly downward tilting and positioning, but the upper and lower flanges 631, 632 of the inclined slideway 63 are limited so that the pulley 21 will not shake up and down, preventing the drawer 20 from colliding with each other; The stopper 611 and the stopper 70 at the front end of the inner guide rail 60 of the utility model, because the stopper 611 is connected with the side wall 64 and has flexibility, the front and rear positions can be adjusted by tilting the stopper 611, which can make the drawer panel The position of the depression between 22 and the side of the table body is set, and because of the forward movement of the position of the guide wheel 80, the entrance 612 of the pulley has a stronger external force resistance structure, which can make the commonly used inner guide rail often unable to The situation of deformation and fracture under heavy external force will not occur on the inner guide rail 60 of the present utility model.

As above-mentioned inner guide rails for desks and cabinet drawers can make desks and cabinets made of metal more practical and durable.
