Description

Technical Field

[0001] This utility model relates to the field of drawer slide technology, specifically a drawer guide rail with an auxiliary load-bearing structure. Background Technology

[0002] Drawer slides are devices made of metal or other materials, consisting of grooves or ridges, that support, secure, and guide moving devices or equipment while reducing friction. The longitudinal grooves or ridges on the surface of the drawer slides are used to guide and secure the drawer.

[0003] Drawer slides typically guide the drawer through openings in the inner wall of the drawer body. When the drawer is fully pulled out, it puts a lot of pressure on the support points of the slides. However, existing drawer slides lack a support mechanism, which can easily lead to breakage at the support points after prolonged use. Therefore, we need a drawer slide with an auxiliary load-bearing structure. Utility Model Content

[0004] The purpose of this invention is to provide a drawer slide with an auxiliary load-bearing structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drawer slide with an auxiliary load-bearing structure, comprising a slide block, the slide block being disposed within a cabinet, a slide groove being provided inside the cabinet, a drawer being disposed inside the cabinet, a slide block being fixedly installed on the side wall of the drawer, the slide block being slidably connected to the inner wall of the slide groove, a push plate being fixedly installed on the outer wall of the drawer, a support mechanism being disposed inside the cabinet, and a snap-fit ​​mechanism being disposed on the drawer;

[0006] The support mechanism includes:

[0008] A slider, which is used to drive the connecting rod to slide;

[0009] A connecting rod, used for connecting the slider and the support plate;

[0010] A support plate, which is used to support the drawer.

[0011] Preferably, a sliding groove is provided on the inner wall of the cabinet. By setting the sliding groove at an inclination, the slider can drive the connecting rod to move to the left and gradually rise. The slider is slidably connected to the inner wall of the sliding groove, and the outer wall of the slider is fixedly connected to one end of the connecting rod. A support plate is fixedly installed on the other end of the connecting rod.

[0012] Preferably, the support plate is provided with ball bearings inside, and the ball bearing array is provided on the support plate. The ball bearings are located at the bottom of the drawer. The connecting rod can drive the ball bearings inside the support plate to move to the left to fit and support the bottom wall of the drawer.

[0013] Preferably, the inner wall of the slide is fixedly connected to one end of the bearing spring, and the other end of the bearing spring is fixedly connected to the outer wall of the slider. The elastic force of the bearing spring can cause the slider to drive the connecting rod to reset. A pressing rod is fixedly installed on the bottom wall of the drawer, and the pressing rod is located on the side of the connecting rod.

[0014] Preferably, the locking mechanism includes a fixing block, which is fixedly installed on the outer wall of the drawer.

[0015] Preferably, the outer wall of the rotating rod is fixedly connected to one end of the torsion spring, and the other end of the torsion spring is fixedly connected to the inner wall of the fixing block. The torsion spring is in a torsional state, and the elastic force of the torsion spring causes the rotating rod to drive the limiting block on the outer wall of the curved plate to flip upward and lock onto the outside of the cabinet.

[0016] Compared with the prior art, this utility model provides a drawer slide with an auxiliary load-bearing structure, which has the following beneficial effects:

[0017] 1. The drawer guide rail with auxiliary load-bearing structure, through the inclined setting of the slide groove in the support mechanism, allows the slider to drive the connecting rod to move to the left and gradually rise. The connecting rod drives the ball bearings inside the support plate to move to the left and rise at the same time, providing close support to the bottom wall of the drawer. This can prevent excessive force at the support point of the drawer. At the same time, the elastic force of the load-bearing spring can make the drawer slide back to its original position, making it easy to use again.

[0018] 2. The drawer guide rail with auxiliary load-bearing structure can cause the rotating rod to drive the limiting block on the outer wall of the curved plate to flip upward through the elastic force of the torsion spring in the snap-fit ​​mechanism. The limiting block is snapped on the outside of the cabinet to prevent the drawer from moving into the inside of the cabinet, making it easy for the user to take out items. By pushing the end of the curved plate, the limiting block can be released, making it easy to close the drawer. Attached Figure Description

[0027] In this embodiment, a support mechanism 6 is provided inside the cabinet 1. By tilting the slide groove 61 in the support mechanism 6, the slider 62 can drive the connecting rod 63 to move to the left and gradually rise. The connecting rod 63 drives the ball bearing 65 inside the support plate 64 to move to the left and rise to fit and support the bottom wall of the drawer 3. This can prevent excessive force at the support point of the drawer 3. At the same time, the elastic force of the bearing spring 66 can make the drawer 3 slide back to its original position, making it easy to use again.

[0028] In this embodiment, the drawer 3 is provided with a locking mechanism 7. The spring force of the torsion spring 75 in the locking mechanism 7 can cause the rotating rod 72 to drive the limiting block 74 on the outer wall of the bent plate 73 to flip upward. The limiting block 74 is locked to the outside of the cabinet 1 to prevent the drawer 3 from resetting and moving into the inside of the cabinet 1, making it convenient for the user to take out items. By pushing the end of the bent plate 73, the limiting block 74 can be released, making it convenient to close the drawer 3.

[0029] The aforementioned support mechanism 6 includes a slide groove 61. The slide groove 61 is formed on the inner wall of the cabinet 1. Due to the inclined arrangement of the slide groove 61, the slider 62 can drive the connecting rod 63 to move to the left while gradually rising. The slider 62 is slidably connected to the inner wall of the slide groove 61. The outer wall of the slider 62 is fixedly connected to one end of the connecting rod 63. A support plate 64 is fixedly installed on the other end of the connecting rod 63. Ball bearings 65 are arranged inside the support plate 64 in an array. The ball bearings 65 are located at the bottom of the drawer 3. The connecting rod 63 can drive the ball bearings 65 inside the support plate 64 to move to the left. The bottom wall of drawer 3 is fitted and supported to prevent excessive force at the support point of drawer 3. The inner wall of slide 61 is fixedly connected to one end of bearing spring 66, and the other end of bearing spring 66 is fixedly connected to the outer wall of slider 62. The elastic force of bearing spring 66 can cause slider 62 to drive connecting rod 63 to reset. A pressing rod 67 is fixedly installed on the bottom wall of drawer 3. The pressing rod 67 is located on the side of connecting rod 63. Drawer 3 can drive pressing rod 67 on the bottom wall to move outward of cabinet 1 and press connecting rod 63, which can cause connecting rod 63 to drive slider 62 to slide to the left on the inner wall.

[0030] The aforementioned locking mechanism 7 includes a fixing block 71, which is fixedly installed on the outer wall of the drawer 3. A rotating rod 72 is rotatably connected to the inner wall of the fixing block 71. A bent plate 73 is fixedly installed on the outer wall of the rotating rod 72. A limiting block 74 is fixedly installed on the bent plate 73. One end of the outer wall of the rotating rod 72 is fixedly connected to a torsion spring 75, and the other end of the torsion spring 75 is fixedly connected to the inner wall of the fixing block 71. The torsion spring 75 is in a torsional state. The elastic force of the torsion spring 75 causes the rotating rod 72 to drive the limiting block 74 on the outer wall of the bent plate 73 to flip upward, so that the limiting block 74 can be locked on the outside of the cabinet 1, preventing the drawer 3 from resetting and moving into the inside of the cabinet 1 due to the elastic force of the bearing spring 66.

[0031] In this embodiment, when it is necessary to retrieve items from inside drawer 3, the push plate 5 is pulled outwards from cabinet 1, causing drawer 3 to move outwards from cabinet 1. Simultaneously, drawer 3 moves the pressing rod 67 on its bottom wall outwards from cabinet 1, pressing the connecting rod 63. This causes the connecting rod 63 to slide to the left along the inner wall of slider 62. The inclined design of the slide groove 61 causes slider 62 to move to the left while gradually rising, leading to the connecting rod 63 moving the ball bearing 65 inside support plate 64 to the left and rising simultaneously. Finally, the ball bearing 65 fits against the bottom wall of drawer 3 for support, preventing excessive force at the support point of drawer 3. At the same time, drawer 3 moves the fixing block 7 on the outer wall. 1. Move to the left, and then through the fixing block 71, drive the limiting block 74 on the outer wall of the curved plate 73 to move to the left out of the cabinet 1. At this time, through the elastic force of the torsion spring 75, the rotating rod 72 drives the limiting block 74 on the outer wall of the curved plate 73 to flip upward, so that the limiting block 74 is locked on the outside of the cabinet 1, preventing the drawer 3 from returning to the inside of the cabinet 1 due to the elastic force of the bearing spring 66, making it convenient for the user to take out the items. After taking out the items, push the end of the curved plate 73 to drive the limiting block 74 to release the limit. At this time, through the elastic force of the bearing spring 66, the slider 62 drives the connecting rod 63 to return to the original position, so that the connecting rod 63 presses the outer wall of the pressing rod 67, so that the pressing rod 67 drives the drawer 3 to return to the original position, making it convenient for use again.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
