Adjustable damping rebounding slide rail and drawer assembly

Abstract

The utility model discloses an adjustable damping rebound sliding rail which comprises an outer rail, an inner rail and an adjusting piece, and a damping device is arranged at the rear end of the outer rail. The inner rail is arranged in the outer rail in a sliding mode, and a shifting piece matched with the damping device is arranged on the inner rail. The adjusting piece is arranged on the shifting piece in a penetrating mode and rotationally connected to the inner rail. The shifting piece can be driven to move in the front-back direction relative to the inner rail by adjusting the adjusting piece. When the inner rail is pushed to slide relative to the outer rail until the inner rail is close to the damping device, the inner rail can be driven to slide relative to the outer rail in a damping mode through mutual cooperation of the shifting piece and the damping device. Therefore, by adjusting the adjusting piece in the damping rebounding sliding rail on one side of the drawer, the shifting pieces can be driven to move in the front-back direction, so that it is guaranteed that the shifting pieces in the damping rebounding sliding rails on the two sides of the drawer can be matched with the damping device at the same time to achieve damping buffering, and it is guaranteed that closing gaps of the left side and the right side of a panel of the drawer are consistent after the drawer is closed in a buffered mode; and therefore, the overall attractiveness of the drawer assembly is ensured.

Description

Technical Field

[0001] The utility model relates to the technical field of hardware accessories, in particular to an adjustable damping rebound slide rail and a drawer assembly. Background Art

[0002] In order to improve the convenience of the opening and closing operation of the slide rail, many functional accessories applied to the slide rail have appeared on the market, such as dampers for buffering the closing of the slide rail or rebounders for pressing and rebounding the slide rail to open. In recent years, in order to achieve the functions of damping closure and pressing and rebounding at the same time, some merchants have designed damping and rebounding slide rails, but most damping and rebounding slide rails do not have an adjustment function, so there are the following problems in actual use:

[0003] (1) Since the damping rebound slide rails are respectively installed on the left and right side walls of the drawer, due to the existence of parts manufacturing and assembly errors during the assembly process, the closing gaps on the left and right sides of the panel of the drawer are inconsistent after the damping buffer is closed, thus affecting the overall aesthetics; (2) Since a press-and-rebound operation is required, a certain closing gap needs to be left between the panel and the cabinet body after the drawer buffer is closed. When the closing gap is too small, the pressing operation cannot be achieved, and when the closing gap is too large, it is not only unsightly, but may also affect the sealing performance of the drawer.

[0004] Therefore, how to design a damping rebound slide rail with an adjustment function is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] In order to overcome the defects of the above-mentioned prior art, the utility model provides an adjustable damping rebound slide rail, which can not only ensure that the closing gaps on the left and right sides of the drawer panel are consistent, but also can adjust the size of the closing gap, and is highly practical.

[0010] An adjusting member, which is inserted through the toggle plate and rotatably connected to the inner rail; by adjusting the adjusting member, the toggle plate can be driven to move in the front-rear direction relative to the inner rail;

[0011] When the inner rail is pushed to slide relative to the outer rail until it approaches the damping device, the inner rail can be driven to slide relative to the outer rail in a damping manner through the cooperation between the paddle plate and the damping device.

[0015] Furthermore, it also includes a plurality of fixed shafts, the toggle plate is provided with a plurality of second guide slots adapted to the fixed shafts, the fixed shafts are passed through the second guide slots and fixed to the inner rail;

[0020] The damping member is arranged on the sliding frame; the tension member is arranged between the fixed frame and the sliding frame. When the tension member releases the elastic force and pulls the sliding frame to slide in the direction close to the fixed frame, under the action of the damping member, the sliding frame can achieve damping buffering relative to the fixed frame.

[0021] Furthermore, a shift block is rotatably connected to the sliding frame; a first slide slot is provided on the fixed frame for inserting one end of the shift block, and the first slide slot includes a straight slot section and a first bending section connected to one end of the straight slot section;

[0022] The shifting piece is provided with a guide groove for guiding the shifting block to leave the first bending section and slide into the straight groove section, and the guide groove is provided with a first protrusion that can abut against the shifting block.

[0023] Furthermore, it also includes a rebound device, which includes a slider slidably set on the fixed frame and an elastic member connected to the slider, and the slider partially passes through the sliding frame; the shift block is provided with a second protrusion that abuts and cooperates with the slider.

[0024] Furthermore, the first slide groove further includes a second bending section connected to the other end of the straight groove section, and the bending direction of the second bending section is opposite to the bending direction of the first bending section.

[0045] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0046] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0048] See also Figure 1-13 The utility model provides a drawer assembly, including a cabinet 15, a drawer 14 and adjustable damping rebound slide rails arranged on the left and right sides of the drawer 14, the adjustable damping rebound slide rails including an outer rail 1 and an inner rail 2 slidably arranged in the outer rail 1, the outer rail 1 is fixed on the inner wall of the cabinet 15, the inner rail 2 is fixed on the left wall or the right wall of the drawer 14, and the drawer 14 is slidably arranged in the cabinet 15 through the adjustable damping rebound slide rails.

[0049] In order to increase the sliding stroke of the inner rail 2, a middle rail 3 is also provided between the outer rail 1 and the inner rail 2. Of course, in other embodiments, in order to achieve a larger sliding stroke, a plurality of middle rails 3 may be provided, which are not limited here.

[0050] Furthermore, a damping device is provided at the rear end of the outer rail 1, and a toggle piece 4 cooperating with the damping device is provided on the inner rail 2; wherein, an adjusting member 5 is provided on the toggle piece 4 and rotatably connected to the inner rail 2, and by adjusting the adjusting member 5, the toggle piece 4 can be driven to move in the front-rear direction relative to the inner rail 2. Thus, when the inner rail 2 is pushed to slide relative to the outer rail 1 until it approaches the damping device, the toggle piece 4 and the damping device cooperate with each other, and the inner rail 2 can be driven to slide relative to the outer rail 1 with damping.

[0051] Specifically, the adjusting member 5 is an eccentric nail, which includes a main shaft and an eccentric shaft arranged at the bottom of the main shaft. The toggle plate 4 is provided with a first guide slot 401 adapted to the main shaft, and the eccentric shaft passes through the first guide slot 401 and is rotatably connected to the inner rail 2; when the eccentric nail is rotated, the main shaft and the first guide slot 401 cooperate to drive the inner rail 2 to move forward and backward relative to the outer rail 1. Preferably, the first guide slot 401 is extended in the up-down direction.

[0052] Therefore, by adjusting the adjustment part 5 in the damping rebound slide rail on one side of the drawer 14, the toggle plate 4 can be driven to move in the front-to-rear direction relative to the inner rail 2, thereby ensuring that the toggle plates 4 in the damping rebound slide rails on both sides of the drawer 14 can cooperate with the damping device at the same time to achieve damping buffering, thereby ensuring that the closing gaps on the left and right sides of the panel of the drawer 14 are consistent after the buffering closure, thereby ensuring the overall aesthetics of the drawer 14 assembly.

[0053] In addition, when the size of the closing gap of the drawer 14 panel needs to be adjusted, the adjusting members 5 in the damping rebound slide rails on both sides of the drawer 14 can be adjusted at the same time, so that the toggle pieces 4 in the damping rebound slide rails on both sides move forward or backward at the same time, thereby making the drawer 14 cooperate with the damping device faster or slower to achieve damping buffering, thereby adjusting the size of the closing gap, such as Figure 11-12 shown.

[0054] Furthermore, in order to further improve the sliding stability of the toggle piece 4, the damping rebound slide rail is further provided with a plurality of fixed shafts 6, and the toggle piece 4 is provided with a plurality of second guide slots 402 adapted to the fixed shafts 6, and the fixed shafts 6 are passed through the second guide slots 402 and fixed to the inner rail 2; when the adjusting member 5 is adjusted, the movement of the inner rail 2 can be guided by the cooperation between the fixed shafts 6 and the second guide slots 402. Preferably, the second guide slots 402 are extended in the front-rear direction.

[0055] See also Figure 3-10 The damping device includes a fixed frame 8 fixedly arranged at one end of the outer rail 1, a sliding frame 7 slidably arranged in the outer rail 1 and capable of sliding toward or away from the fixed frame 8, a damping member 13 arranged on the sliding frame 7, and a tension member 9 arranged between the fixed frame 8 and the sliding frame 7 and used for pulling the sliding frame 7 to slide toward the fixed frame 8. Specifically, the damping member 13 is a telescopic cylinder, and a sleeve-shaped mounting frame for mounting the telescopic cylinder is provided at one end of the sliding frame 7 close to the fixed frame 8. Conical limiting rails 802 are respectively provided on both sides of the rear end of the fixed frame 8, and the side walls of the limiting rails 802 are inclined from the direction away from the fixed frame 8 to the direction close to the fixed frame 8; the telescopic end of the telescopic cylinder abuts against the side walls of the limiting rails 802.

[0056] Therefore, when the sliding frame 7 can be pulled to slide in the direction close to the fixed frame 8 under the action of the tension member 9, the telescopic end of the telescopic cylinder can be compressed due to the gradual reduction in the width of the limit rail 802, so that the pressure can be converted into resistance to the retraction of the tension member 9, thereby realizing the damped sliding of the sliding frame 7.

[0057] In this embodiment, the tension member 9 is a spring, and two of them are arranged at intervals; one end of the spring is hung on the sliding frame 7, and the other end is hung on the fixing frame 8.

[0058] Furthermore, the sliding frame 7 is also rotatably connected with a shift block 10, and the fixed frame 8 is provided with a first slide groove 801 for inserting one end of the shift block 10, and the first slide groove 801 includes a straight groove section 8011 and a first bent section 8012 connected to one end of the straight groove section 8011. Specifically, a limiting column is provided at one end of the shift block 10, and the sliding frame 7 is provided with an arc hole for the limiting column to pass through and for limiting the swing of the limiting column, and the lower end of the limiting column is inserted into the first slide groove 801. Among them, the shifting piece 4 is provided with a guide groove 403 for guiding the sliding of the limiting column, and the guide groove 403 is provided with a first protrusion 404 that can abut and cooperate with the limiting column. The guide groove 403 includes a first guide section extending horizontally and a second guide section connected to the first guide section and bent.

[0059] Therefore, when the limit column is located in the first bending section 8012, the limit column is in a clamping state so that the sliding frame 7 is also in a locked state, and the sliding frame 7 is located on the side away from the fixed frame 8 and the tension member 9 is stretched; when the inner rail 2 is pushed to slide until it is close to the damping device, the limit column slides into the guide groove 403 and slides along the first guide section until it slides into the second guide section. Under the guidance of the second guide section, the limit column disengages from the first bending section 8012 and enters the straight groove section 8011. At this time, the sliding frame 7 is unlocked and, under the action of the tension member 9, drives the sliding frame 7 to slide along the straight groove section 8011 and gradually approaches the fixed frame 8, thereby realizing the damping and buffering movement of the inner rail 2.

[0060] Furthermore, it also includes a rebound device, which includes a slider 12 slidably set on the fixed frame 8 and an elastic member 11 connected to the slider 12, and the slider 12 is set through the sliding frame 7; the toggle piece 4 is provided with a second protrusion 405 that abuts and cooperates with the slider 12. Specifically, the elastic member 11 is a spring and one end is hung on the fixed frame 8, and the other end is connected to the slider 12. Therefore, under the action of the tension member 9, the toggle piece 4 drives the inner rail 2 to slide dampingly, while the second protrusion 405 can abut against the slider 12 and drive the slider 12 to slide to stretch the elastic member 11, thereby realizing energy storage for the rebound device. It should be noted that the tension of the tension member 9 is greater than the elastic force of the elastic member 11.

[0061] The first slide slot 801 further includes a second bending section 8013 connected to the other end of the straight slot section 8011, and the bending direction of the second bending section 8013 is opposite to the bending direction of the first bending section 8012. Therefore, when the inner rail 2 is pushed to slide again in the direction close to the fixing frame 8, under the guidance of the second guide section, the limiting column will continue to slide and disengage from the straight slot section 8011 until it enters the second bending section 8013. At this time, the limiting column is separated from the first protrusion 404, and under the action of the elastic member 11, the slider 12 abuts against the second protrusion 405 and slides in the direction away from the fixing frame 8 to achieve ejection. Figure 8-10 shown.

[0062] In addition, the end of the second protrusion 405 away from the fixing frame 8 is also provided with an abutting surface for abutting against the shifting block 10. When the inner rail 2 is completely pulled out, the abutting surface of the second protrusion 405 will abut against the shifting block 10 and drive it to slide, thereby driving the sliding frame 7 to slide in the direction away from the fixing frame 8 and synchronously stretch the tension member 9, and in turn drive the limiting column to slide from the second bending section 8013 to the straight groove section 8011, then slide along the straight groove section 8011 and re-enter the first bending section 8012, at which time the sliding frame 7 is locked again and synchronously completes the stretching of the tension member 9 to realize energy storage of the damping device. At this time, the second protrusion 405 and the limiting column are in a separated state, and then the inner rail 2 can continue to be pulled out.

[0063] In summary, the adjustable damping rebound slide rail and drawer assembly of the utility model has the following beneficial effects:

[0064] (i) By adjusting the adjustment member 5 in the damping rebound slide rail on one side of the drawer 14, the toggle piece 4 can be driven to move in the front-rear direction relative to the inner rail 2, thereby ensuring that the toggle pieces 4 in the damping rebound slide rails on both sides of the drawer 14 can cooperate with the damping device at the same time to achieve damping buffering, thereby ensuring that the closing gaps on the left and right sides of the panel of the drawer 14 are consistent after the buffering closure, thereby ensuring the overall aesthetics of the drawer 14 assembly;

[0065] (ii) When it is necessary to adjust the size of the closing gap of the drawer 14 panel, the adjusting members 5 in the damping rebound slide rails on both sides of the drawer 14 can be adjusted simultaneously, so that the paddle pieces 4 in the damping rebound slide rails on both sides move forward or backward simultaneously, thereby making the drawer 14 cooperate with the damping device faster or slower to achieve damping buffering, thereby achieving the adjustment of the size of the closing gap.
