Description

Technical Field

[0001] The present application relates to the technical field of slide rails, and more specifically, to a multi-section slide rail. Background Art

[0002] Slide rails, also known as guide rails and slideways, refer to hardware connection components fixed to the cabinet body of furniture for the movement of drawers or cabinet panels of furniture in and out; slide rails are suitable for drawer connections of wooden and steel drawers of cabinets, furniture, document cabinets, bathroom cabinets and other furniture.

[0003] In the related art, in order to facilitate the extension of the table top of the dining table, for example, the patent with the prior art publication number CN220236350U provides a dining table with an expandable and extendable table top. The device is provided with a side panel seat at the bottom of the supporting beam of the side table top, and the side panel seat is provided with a guide shaft slidably connected to the track groove. The side panel seat and the side frame are connected by a slide rail, and reinforced corner blocks are fixed to each corner of the rectangular frame. The reinforced corner blocks are installed with a roller assembly, and the wheel body of the roller assembly is supported on the bottom surface of the supporting beam.

[0004] Although the above-mentioned prior art solution can achieve the effect of extending the desktop by adjusting the distance between the side panel seats and the side frames by sliding the side panel seats and the side frames through the slide rails, the extended width of the desktop is affected by the length of the slide rails. If the slide rails are long, the initial area of ​​the desktop will be large, which is not convenient for storage and placement. If the initial length of the slide rails is short, the extension distance of the desktop will be reduced, which is difficult to adapt to long-distance extension requirements.

[0005] In view of this, we propose a multi-section slide rail. Utility Model Content

[0006] The purpose of the present application is to provide a multi-section slide rail, which solves the technical problem that the slide rail is difficult to adapt to the long-distance extension demand and achieves the technical effect of being able to achieve long-distance extension according to demand.

[0024] The present application is further described in detail below in conjunction with the accompanying drawings.

[0025] Reference Figure 1 and Figure 2 The embodiment of the present application discloses a multi-section slide rail, which is composed of a plurality of slide rail units, including a connecting member 1, and a plurality of slide rail units are symmetrically arranged on both sides of the connecting member 1; the slide rail unit includes an outer sleeve 2 and an inner sleeve 3, the outer sleeve 2 is slidably arranged on the outside of the inner sleeve 3, the outer sleeves 2 in the plurality of slide rail units are fixedly connected to the adjacent inner sleeves 3, the two adjacent outer sleeves 2 are fixedly arranged on the outside of the connecting member 1, and the outer side of the outermost inner sleeve 3 is fixedly provided with a right-angle plate 4 for connecting to the desktop.

[0026] Several slide rail units are connected by a connecting piece 1. When the connecting piece 1 is fixed on the table leg, the connecting piece 1 and the slide rail unit are supported by the fixed table leg, thereby ensuring the stability of the multi-section slide rail when supporting the table top. When the table top is extended, the right-angle plate 4 is driven to move by pulling the table top to both sides, and the right-angle plate 4 drives the inner sliding sleeve 3 to slide on the inner side of the outer sliding sleeve 2, and the outer sliding sleeve 2 drives the inner sliding sleeve 3 fixedly connected on the outside to continue to slide on the inner side of the next outer sliding sleeve 2, and so on, so that each slide rail unit can be slid and extended, and then the effect of long-distance adjustment is achieved through several slide rail units.

[0027] Reference Figure 1 The outer sleeve 2 and the inner sleeve 3 are both U-shaped structures, and the open end of the inner sleeve 3 is slidably arranged on the inner side of the open end of the outer sleeve 2; a sliding shaft 31 is symmetrically fixedly arranged on the outer side of the inner sleeve 3, and a sliding groove 21 is arranged on the inner side of the outer sleeve 2 corresponding to the sliding shaft 31, and the sliding shaft 31 is slidably arranged on the inner side of the sliding groove 21.

[0028] By fixing the sliding shafts 31 on both sides of the inner sliding sleeve 3 and cooperating with the sliding grooves 21 , the outer sliding sleeve 2 and the inner sliding sleeve 3 can slide stably, and the strength of the inner sliding sleeve 3 is increased.

[0029] Reference Figure 1 Each slide rail unit also includes a limit assembly 5, which is arranged between the outer sleeve 2 and the inner sleeve 3. The limit assembly 5 includes a stopper A51 and a stopper B52. The stopper A51 is fixedly arranged at both ends of the outer sleeve 2, and the stopper B52 is fixedly arranged at one end of the inner sleeve 3.

[0030] When the inner sleeve 3 slides on the inner side of the outer sleeve 2, it drives the stopper B52 to move on the inner side of the outer sleeve 2. When the stopper B52 moves to contact with the stopper A51, it means that the inner sleeve 3 has slid to the maximum limit. At this time, the inner sleeve 3 drives the inner sleeve 3 on the other side of the outer sleeve 2 to continue sliding through the limiting assembly 5 to prevent the outer sleeve 2 and the inner sleeve 3 from separating during the sliding process.

[0031] Reference Figure 1 and Figure 2 A mounting hole 41 is provided on the top of the right-angle plate 4 , and the mounting hole 41 is located at the diagonal position formed by the right-angle plates 4 on both sides.

[0032] The installation holes 41 are provided to facilitate fixing the right-angle plate 4 on the bottom of the table top, and the two table tops can be connected through the installation holes 41 provided diagonally, and when the two table tops are pulled, the outer sliding sleeve 2 and the inner sliding sleeve 3 are driven to slide and extend.

[0033] Reference Figure 1 Five slide rail units are arranged on both sides of the connecting member 1, and the length of each slide rail unit is 410 mm.

[0034] In summary, when the multi-section slide rail disclosed in the embodiment of the present application is used, two multi-section slide rails are aligned and placed, and the right-angle plate 4 is installed on the bottom of the desktop through the mounting holes 41 at the diagonal positions. At this time, two right-angle plates 4 are fixedly installed on the bottom of each desktop, and then the connecting piece 1 in each multi-section slide rail is fixed to the fixed table leg, and the fixed table leg does not move when extended; at this time, the slide rail unit with a length of 410mm supports the initial desktop, reducing space occupancy for easy storage and placement, and when the length of the desktop needs to be extended, the right-angle plate 4 is driven to move by pulling the desktop to both sides, and the right-angle plate 4 drives the inner sliding sleeve 3 to move in the outer sliding sleeve 2 The inner sleeve 3 slides inside, and the outer sleeve 2 drives the inner sleeve 3 fixedly connected on the outside to continue to slide inside the next outer sleeve 2. When the inner sleeve 3 slides inside the outer sleeve 2, it drives the stopper B52 to move inside the outer sleeve 2. When the stopper B52 moves to contact with the stopper A51, it indicates that the inner sleeve 3 has slid to the maximum limit. At this time, the inner sleeve 3 drives the inner sleeve 3 on the other side of the outer sleeve 2 to continue to slide through the limiting assembly 5 to prevent the outer sleeve 2 and the inner sleeve 3 from separating during the sliding process. By analogy, each slide rail unit can be slid and extended, and then the effect of long-distance adjustment can be achieved through a plurality of slide rail units.
