Description

Slide rail and drawer positioning device

technical field

The invention relates to the technical field of a positioning device for a cabinet drawer slide rail. In particular, it relates to the technical field of a detachable slide rail and a drawer positioning device that can be adjusted and positioned arbitrarily in the width direction of the drawer. It is suitable for cabinet slide rails and drawer positioning devices for storage and storage of design base plans, scroll calligraphy and paintings, and precious items in archives (rooms), museums, art and art galleries, exhibition halls, and painting warehouses.

Background technique

At present, there are many designs of slide rails and drawer positioning devices at home and abroad, but most of them belong to the design of the structure of drawer longitudinal movement and positioning. Generally, there is no angular plate for installing drawers on the drawer slide rails, and the drawers and slide rails are directly connected with screws. , because the width of the frame of the slide rail on which the drawer is installed and the width of the drawer has been fixed, if the gap between the sliding frame and the drawer cannot be adjusted, it may happen that the drawer is too loose or too tight when the drawer is pulled, and even the drawer is easy to fall because the gap is too large , if precious items are placed in it, it will cause great loss. The structural design of drawer longitudinal movement positioning is more representative such as a "positioning device for detachable computer desk keyboard drawer slide rail" disclosed in Chinese patent specification 01259939.5, as shown in Figure 5 and Figure 6, its main body The structure includes a slide frame 10, a steel ball slide rail 15, a slide bar 20 and a brake piece 30 fixed on the slide bar; one end of the slide frame 10 is provided with a blocking piece 12, and the other end is provided with a buckle piece 14, the buckle Two protrusions 142 are formed on the piece; a window hole 22 can be set in the middle of the slide bar 20 that can slide relatively in the sliding frame 10, and a fixed hook 24 and a positioning hook 26 are respectively provided at the front and rear of the window hole, wherein the positioning hook base is formed with a Insertion hole; between the sliding frame 10 and the sliding bar 20, there is a steel ball slide rail providing the sliding function of the sliding bar and a braking member 30 fixed on the sliding bar. There is an outwardly expanded transverse lug 36, and each transverse lug has a curved concave portion 361 and a guide portion 363, and the curved concave portion 363 forms a buckle groove 365 with one end of the brake component to engage with the buckle component. The protruding block 142; by virtue of the structural design of the lug and its own lateral elastic contraction, the sliding operation process of the brake member 30 relative to the sliding frame 10 can be smoother, and the positioning of the drawer is more reliable when it is pulled out. When the drawer is closed, it only needs to be pushed back with light force; the above-mentioned "positioning device for the slide rail of the detachable computer desk keyboard drawer" has the advantages of flexible structure, labor saving, convenience, etc. The gap between the steel ball slide rail 15 and the drawer installed in the steel ball slide rail 15 is not adjustable, which often causes too loose or too tight failures when the drawer is pulled.

Contents of the invention

The object of the present invention is to make up for the above-mentioned defects, and to provide a slide rail and drawer positioning device with a gap adjusting device designed at the junction of the slide rail and the drawer.

The purpose of the present invention is achieved by providing a slide rail and drawer positioning device with the following structure, which includes a frame, a slide rail placed between the two sides of the frame, and a slide rail placed between the two sides of the frame It is composed of the drawers in between and the hanging fasteners that fix the slide rails on the frame.

The inner sides of the slide rails on both sides are fixedly connected to at least two angled plates that are bent at 90 degrees according to the length of the drawer, and the angled plates are provided for adjusting the distance between the slide rails and the drawer. There is an adjustment hole for the sliding gap, and an adjustment screw is arranged in the adjustment hole of the angle plate and fixedly connected with the adjustment hole of the drawer.

Depending on the length of the drawer, the inner sides of the slide rails generally need to be fixedly connected with two to four angular plates. The angle plate fixedly connected to the inner side of the slide rail is welded to the slide rail.

字形孔。The horizontal clearance adjustment hole for the drawer provided on the angled plate is a waist-shaped hole perpendicular to the moving direction of the drawer. The holes provided on the drawer for adjusting the longitudinal gap of the drawer are waist-shaped holes parallel to the moving direction of the drawer. The holes for vertical and horizontal adjustment of the drawer provided on the angular plate can also be set as the superimposition of the waist circular hole in the horizontal direction and the waist circular hole in the vertical direction.

Zigzag hole.

There are at least two hanging fasteners on the plane of the sliding rail in contact with the frame, which are matched with the mounting holes of the frame. The said hanging fastener is fixedly connected with said slide rail plane by molding. Described slide rail is three-section slide rail.

Compared with the prior art, the present invention has the following advantages: 1. Due to the processing error of the slide rail and the drawer and the thermal expansion and contraction of the material caused by various environmental conditions, the change of the sliding gap between the slide rail and the drawer It can be adjusted to the best state in any timely manner; 2. The components for clearance adjustment are very simple to process and manufacture, and the installation and adjustment are convenient; 3. The slide rail and the frame are connected by hanging fasteners, which is easy to operate.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

1 to 5 show an embodiment of the present invention. The present invention consists of a frame 1, two slide rails 4 between the two sides of the frame 1, a drawer 2 installed between the two sides of the slide rails, and is used to buckle the slide rails. It is composed of hanging fasteners fixed on the frame; the inner sides of the slide rails 4 on both sides are respectively fixedly connected with three angled plates 3 that are bent at 90 degrees, and the angled plates 3 are provided with a device for adjusting the slide rails. The adjustment hole of the sliding gap between the rail 4 and the drawer 2, an adjustment screw 5 is arranged in the adjustment hole of the angle plate 3 and is fixedly connected with the adjustment hole of the drawer 2. The angled plate 3 fixedly connected to the inner side of the slide rail 4 is welded together.

The waist circular hole 7 perpendicular to the moving direction of the drawer provided on the angular plate 3 is used for lateral adjustment of the drawer. The waist circular holes 6 parallel to the moving direction of the drawer provided on the drawer 2 are used for longitudinal adjustment of the drawer.

The sliding gap change between the slide rail and the drawer is adjusted to the best state: the swing gap is not more than 3 mm, so as to ensure the stable and safe use of the table cabinet drawers used for storing and storing scrolls, calligraphy, paintings and precious items.
