Technical Field

[0001] This utility model relates to the field of drawer cabinet technology, specifically a drawer cabinet with adjustable guide rails. Background Technology

[0002] Dressers are a common piece of furniture in daily life, primarily serving to provide categorized storage space for items and help maintain a tidy and organized environment. Because drawers open by pulling them out, they are generally more convenient for accessing small items compared to cabinets with hinged doors, as they don't require additional space in front. Therefore, dressers are widely used in various environments such as living spaces and offices to store clothing, documents, tools, and other miscellaneous items, meeting people's basic storage and management needs.

[0003] In traditional technology, the drawer pull-out stroke of a chest of drawers is usually fixed and not adjustable, which limits its adaptability in specific spaces or situations with special usage needs. On the other hand, the limiting structure in existing technology may be relatively simple, and there is a risk that the drawer may go off the track or collide with the cabinet body under long-term use or accidental force.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 As shown, this utility model provides a technical solution: A drawer cabinet with adjustable guide rails includes a cabinet body 101. A tabletop 102 is bolted to the top of the cabinet body 101. A notch 103 is provided on one side of the cabinet body 101, and two drawers 104 are respectively inserted into the cabinet body 101 along the notch 103 via a rail assembly 105. The rail assembly 105 includes an outer rail 106 and an inner rail 107. The outer rails 106 are in pairs, and each pair of outer rails 106 is bolted to the inner two side walls of the cabinet body 101. A plurality of threaded holes 108 are spaced apart on one side of the top of the outer rails 106. A limit screw 109 is threaded into one of the threaded holes 108. The number of inner rails 107 corresponds to the number of outer rails 106, and their outer end faces are bolted to the two sides of the drawers 104. Limit plates 110 are installed at the inner end faces of the inner rails 107 via pins.

[0017] The above solution utilizes the cabinet as the main support structure for the entire device to achieve stable load-bearing function. The countertop is fixed to the top of the cabinet with bolts to form a complete working or placement surface. A notch on one side of the cabinet provides a passage for the drawers to enter and exit. The drawers are connected to the cabinet via a track assembly to achieve smooth pull-out movement. Groups of outer rails are installed at intervals on the inner wall of the cabinet to establish a fixed sliding track foundation. Multiple threaded holes at the top of the outer rails provide selectable installation points. Limiting screws are screwed into specific threaded holes to form an adjustable stop mechanism. Inner rails are fixed to both sides of the drawers to suspend and guide them into the track system. Limiting plates installed at the ends of the inner rails with pins cooperate with other components to achieve stroke control during sliding.

[0018] In this embodiment, preferably, a sealing plate 111 is bolted to one side of the drawer 104 and fits into the notch 103 of the cabinet body 101, and a handle 112 is threaded to the middle of the other side of the sealing plate 111.

[0019] The above solution involves installing a sealing plate on one side of the drawer to close the cabinet gap, thereby improving the appearance integrity and dustproof effect. The sealing plate is fitted to the edge of the gap to ensure the airtightness of the cabinet interior. The handle is installed in the center of the outer side of the sealing plate to provide a convenient force point for users to operate the drawer opening and closing.

[0020] In this embodiment, preferably, a limiting pad 113 is fixedly installed on one side of the width of the outer rail 106, and ball bearings 114 are provided on the upper and lower sides of the outer rail 106 and roll in cooperation.

[0021] The above scheme uses a limiting pad fixed to the inner wall of the outer rail to limit the insertion depth of the middle rail and provide a buffering and protective effect. Ball bearings are arranged on the upper and lower inner surfaces of the outer rail to form rolling contact with the middle rail to reduce frictional resistance.

[0022] In this embodiment, preferably, the ball bearings 114 are respectively provided with a middle rail 115 and roll in cooperation, and the corner of the top end of the middle rail 115 is respectively raised to form a limiting piece 116.

[0023] The above scheme avoids installation interference by creating a through hole at the end of the middle rail to provide a bolt channel for fixing the outer rail, and achieves multiple sliding functions by installing a steel ball rail inside the middle rail to form a secondary rolling pair with the inner rail.

[0024] In this embodiment, preferably, a plurality of through holes 117 are provided at intervals on the inner end face of the middle rail 115, and steel ball rails 118 are provided inside the middle rail 115 and roll in cooperation.

[0025] The above scheme uses a middle rail positioned between the ball bearings as an intermediate sliding carrier connecting the inner and outer rails, and a limiting piece protruding at the top of the middle rail contacts the limiting screw to limit the maximum pull-out position.

[0026] In this embodiment, preferably, inner rails 107 are slidably installed inside the ball bearing rail 118 and roll in cooperation, and limit blocks 119 are fixedly installed on both sides of the width inside the middle rail 115.

[0027] The above scheme achieves the drawer's extension and retraction by having the inner rail slide inside the ball bearing rail. The relative movement range of the inner rail is controlled by a limit block fixed to the inner wall of the middle rail and working in conjunction with the limit plate.

[0028] In this embodiment, a drawer 104 cabinet with adjustable guide rails is used. The cabinet body 101 serves as the basic structure, with a tabletop 102 bolted to its top to provide a stable support platform. A notch 103 is provided on one side of the cabinet body 101 to facilitate access to the drawer 104. The drawer 104 is inserted into the cabinet body 101 via a track assembly 105, which includes outer rails 106 and inner rails 107. The outer rails 106 are bolted in pairs to the inner side walls of the cabinet body 101, while the inner rails 107 are bolted to the sides of the drawer 104. The drawer 104 is connected to the slide system. When the drawer 104 is pulled out, the inner slide 107 first slides inside the middle slide 115 via the ball bearing slide 118. The ball bearing slide 118 and the middle slide 115 achieve low-friction movement through rolling contact, allowing the drawer 104 to extend or retract smoothly. The limiting plate 110, which is installed at the inner end face of the inner slide 107 via a pin, will abut against the limiting blocks 119 fixedly installed on both sides of the inner width of the middle slide 115 during the sliding process, thereby limiting the range of movement of the inner slide 107 within the middle slide 115, preventing the drawer 104 from being pulled out excessively, and ensuring safe use.

[0029] The middle rail 115 itself utilizes ball bearings 114 arranged on the upper and lower sides inside the outer rail 106 to slide within the outer rail 106. The ball bearings 114 and the outer rail 106 roll in cooperation, further reducing friction and making the movement of the middle rail 115 smoother. A limiting pad 113 is fixedly installed on one side of the width inside the outer rail 106 to limit the final position of the middle rail 115 when it is pushed into the cabinet 101, preventing the middle rail 115 from colliding with the outer rail 106. At the same time, several threaded holes 108 are spaced apart on one side of the top of the outer rail 106. A limiting screw 109 is threadedly installed in one of the threaded holes 108. The limiting screw 109 can abut against the limiting piece 116 formed by the upward protrusion at the corner of the top of the middle rail 115, thereby limiting the movement of the middle rail 115. The drawer can be pulled out at different positions. By adjusting the limit screw 109 inserted into different threaded holes 108, the contact point between the limit screw 109 and the limit piece 116 can be changed, thereby adjusting the sliding distance of the middle rail 115 within the outer rail 106, achieving adjustable drawer stroke to adapt to different usage needs. Several through holes 117 are spaced apart on the inner end face of the middle rail 115. The function of these through holes 117 is to ensure that the bolts used to fix the outer rail 106 can pass smoothly through the middle rail 115 without interference during installation, avoiding the middle rail 115 affecting the firm connection between the bolts and the outer rail 106, because the outer rail 106 is fixed to the side wall of the cabinet 101 by bolts, while the middle rail 115 needs to slide inside the outer rail 106 next to the bolts.

[0030] A sealing plate 111 is bolted to one side of drawer 104. The sealing plate 111 fits snugly against the notch 103 of cabinet 101, serving both aesthetic and dust-proof purposes. A handle 112 is threaded onto the other side of the sealing plate 111, facilitating user operation of drawer 104. The coordinated operation of the entire track system allows drawer 104 to be pulled out through a dual motion: the inner rail 107 slides within the middle rail 115, and the middle rail 115 slides within the outer rail 106. This not only ensures smooth operation of drawer 104 but also provides a flexible user experience through an adjustable limit mechanism.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
