[0001] The utility model relates to the technical field of furniture pressing and rebounding, in particular to an adjusting mechanism for a drawer pressing and rebounding device. Background Art

[0002] Chinese patent document No. 202311701586. X discloses a drawer push-adjustment structure, in which the adjustment part of the adjustment mechanism needs to be driven by an adjustment tool to rotate the eccentric adjustment screw after the moving rail and the drawer are closed, which makes the adjustment more complicated. In addition, the outer shell of the push-rebound device is slidably connected to one side of the moving rail, so that a strip groove is provided on the outer shell of the push-rebound device, and the rivet is inserted into one side of the moving rail through the strip groove. The assembly method is complicated, and the adjustment screw is also connected to the moving rail. The rotation of the adjustment screw drives the moving rail to slide relatively on the push-rebound device. The adjustment screw is connected to the moving rail, and the connection strength is general. The eccentric screw is easy to fall off when it is subjected to severe vibration during shipment.

[0003] Therefore, further improvement is needed. Utility Model Content

[0004] The utility model aims to provide an adjustment mechanism for a drawer push-and-rebound device, wherein a movable block connected to a movable rail is provided on the push-and-rebound device, and the movable block is cooperatively connected with an adjustment member, thereby enhancing the connection strength between the adjustment member and the movable rail, and the adjustment member is not easy to fall out of the push-and-rebound device.

[0005] The purpose of the utility model is achieved in this way:

[0006] A regulating mechanism for a drawer push-and-rebound device comprises an regulating member rotatably arranged on the push-and-rebound device, wherein the push-and-rebound device is provided with a movable block for cooperating and connecting with the regulating member and a movable rail, and the movable block is movably arranged on the push-and-rebound device; the regulating member rotates and acts on the movable block, and the movable block and the movable rail move forward and backward relative to the push-and-rebound device to adjust the front-and-back position between the push-and-rebound device and the movable rail.

[0007] A first sliding connection portion is provided between the pressing and rebounding device and the movable rail, and the pressing and rebounding device is connected to the movable rail through a relative sliding connection portion; when the adjusting member rotates, the movable rail slides relatively on the pressing and rebounding device through the first sliding connection portion, thereby eliminating the method of connecting the pressing and rebounding device and the movable rail by rivets or long strip grooves, thereby improving assembly efficiency.

[0008] A stepless or stepped adjustment matching part is provided between the adjustment part and the movable block, and the adjustment part and the movable block are connected by the adjustment matching part, and the adjustment part is adjusted steplessly or step by step through the stepless or stepped adjustment matching part. The stepless or stepped adjustment matching part positions and rotates the adjustment part, and the adjustment part is fixed at the corresponding position angle after adjustment, so as to prevent the adjustment part from retreating and avoid adjustment failure.

[0009] An adjustment position is provided on the corresponding adjustment piece of the press-rebound device. The adjustment piece is driven to rotate on the press-rebound device directly manually or with the help of an adjustment tool through the adjustment position. The adjustment position allows the user to directly manually rotate the adjustment piece to achieve tool-free adjustment.

[0010] The adjusting member is provided with a rotating member, through which the adjusting member is rotatably connected with the pressing and rebounding device, and when the adjusting member rotates, the rotating member forms a rotating fulcrum of the adjusting member.

[0011] A second sliding connection part is provided between the pressing and rebounding device and the movable block, and the pressing and rebounding device is connected to the movable block through the second sliding connection part in a relatively sliding manner; when the adjusting member rotates, the movable block slides relatively on the pressing and rebounding device through the second sliding connection part. When adjusting, the adjusting member drives the movable block to slide on the pressing and rebounding device through the second sliding connection part, effectively reducing the friction resistance between the movable block and the pressing and rebounding device when the movable block moves.

[0012] The press-rebound device is provided with a connecting piece for connecting the synchronization rod, and a locking piece is provided on the press-rebound device corresponding to the connecting piece. The locking piece is rotatably connected to the connecting piece, and a rotation locking part is provided between the locking piece and the press-rebound device; when the locking piece is rotated to a corresponding position on the connecting piece, it is locked on the press-rebound device by the rotation locking part, so that the connecting piece is fixed on the press-rebound device to prevent the connecting piece from falling out of the press-rebound device during shipment, and the locking piece can be disassembled and assembled on the press-rebound device by rotation, thereby reducing the number of connecting pieces such as screws, improving the assembly effect, shortening the processing cycle of the product, and reducing the processing steps of the product processing threaded hole structure.

[0013] The movable rail slides open and close on the fixed rail; when the movable rail is closed, and the push-rebound device is in a pending state and locked on the fixed rail, the adjusting part rotates and drives the movable block and the movable rail to move forward and backward relative to the push-rebound device and the fixed rail. When the push-rebound device is fixed, the adjusting part can rotate to drive the movable block and the movable rail to move forward and backward relative to the push-rebound device. The front and rear position between the movable rail and the fixed rail can be adjusted, and then the pressing distance (spacing) between the drawer panel and the front side of the cabinet can be adjusted. When there is a manufacturing error in the drawer panel, resulting in the pressing distance between the drawer panel and the front side of the cabinet being too large or too small, the pressing distance can be adjusted by adjusting the mechanism so that the pressing distance is adjusted to an appropriate range without reinstalling the entire drawer.

[0014] There are two moving rails, fixed rails, and push-rebound devices, and a synchronization rod is provided between the two push-rebound devices; when one of the push-rebound devices is unlocked by the corresponding fixed rail, the two push-rebound devices perform corresponding elastic movements through the synchronization rod, so that the two moving rails are synchronously elastically opened on the corresponding fixed rails. The user can press at any position of the drawer panel, and the components on the push-rebound device can perform synchronous movement through the synchronization mechanism, so that the two moving rails of the drawer can synchronously slide and open on the fixed rails, ensuring that the drawer can be completely popped out on the cabinet body, solving the technical problem that the drawer is tilted and stuck on the cabinet body due to unbalanced popping out during the existing drawer push-rebound opening process.

[0015] A drawer is arranged on the movable rail, and the drawer is opened and closed on the cabinet body by sliding the movable rail and the fixed rail; when the adjusting member rotates, the movable rail drives the drawer to move forward and backward relative to the pressing rebound device, the fixed rail and the cabinet body to adjust the front and rear position between the drawer and the cabinet body.

[0016] The beneficial effects of the utility model are as follows:

[0017] The pressing and rebounding device is provided with a movable block connected with the moving rail, and the movable block is cooperatively connected with the adjusting member, thereby enhancing the connection strength between the adjusting member and the moving rail, and the adjusting member is not easy to fall out of the pressing and rebounding device.

[0018] The movable rail slides relatively on the pressing and rebounding device through the first sliding connection part, ensuring the sliding connection between the movable rail and the pressing and rebounding device, and eliminating the rivet and long strip groove matching connection between the pressing and rebounding device and the movable rail, thereby improving assembly efficiency.

[0019] The corresponding adjusting piece on the press-rebound device is provided with an adjusting position, and the adjusting position enables the user to directly manually rotate the adjusting piece to achieve tool-free adjustment. BRIEF DESCRIPTION OF THE DRAWINGS
