Description

Technical Field

[0001] This invention relates to the field of drawer technology, and in particular to a connection device and drawer with adjustable limit position. Background Technology

[0002] Chinese Patent Document No. CN217390273U disclosed on September 9, 2022, an adjustable connecting device and a fixing device and a furniture drawer thereof. The connecting device includes a connecting body, a connecting part extending from one side of the connecting body, and an adjusting part and a cover plate connected through the connecting part. A connecting through hole is provided on the connecting part, and a cover plate through hole is provided on the cover plate. The adjusting part is threadedly rotated on the connecting through hole, and when rotating, it is guided and limited to slide on the connecting through hole and the cover plate through hole relative to the connecting body. When this connecting device is adjusted by the adjusting member, the adjusting member rotates on the connecting through hole with its thread. During rotation, it guides and limits the sliding of the adjusting member relative to the main body of the connecting member on the connecting through hole and the through hole of the cover plate. When it slides a certain distance relative to the main body of the connecting member in one direction, it is limited to the limiting step by the limiting guide part. When it slides a certain distance relative to the main body of the connecting member in the other direction, it is limited to the cover plate by the limiting guide part. The above-mentioned limiting method of the adjusting member is to limit the limiting guide part by the limiting step and the cover plate, which is a vertical limiting method. This limiting method has the following defects: the adjusting member is rotated by a screwdriver. If the screwdriver is turned too forcefully, the limiting will fail, the connecting part and the cover plate will be pushed open, causing the two to be forcibly separated and resulting in damage to the connecting part and the cover plate.

[0003] Therefore, further improvements are necessary. Summary of the Invention

[0004] The purpose of this invention is to provide a simple, easy-to-adjust, reliable, and highly practical adjustable connection device and drawer to overcome the shortcomings of the prior art.

[0005] A limit-adjustable connecting device designed for this purpose includes a connecting body and an adjusting member. A connecting member is provided on one side of the connecting body, and a through hole is provided on the connecting member. An adjusting fit is provided between the adjusting member and the through hole. The adjusting member is rotatably adjusted on the through hole through the adjusting fit and slides on the through hole during rotational adjustment. The device is characterized in that: at least one limiting fit is provided between the adjusting member and the through hole, and the adjusting member is limited to rotate and adjust on the through hole in the rotational direction through the limiting fit, so that the adjusting member slides on the through hole in a limited manner.

[0006] Two limiting fitting parts are provided. When the adjusting member rotates in both clockwise and counterclockwise directions, it is limited to rotate in the direction of rotation by the corresponding limiting fitting parts and adjusted on the through hole, so that the adjusting member slides on the through hole at the upper and lower limits.

[0007] The limiting fitting part includes a limiting part provided on the adjusting member and a stop part provided on the through hole. When the adjusting member is rotated for adjustment, it is limited by the limiting part to the stop part of the through hole in the direction of rotation.

[0008] The connector includes a connecting part and a cover plate that are connected to each other. The connecting part extends and is disposed on one side of the connecting body. The through hole includes a first through hole disposed on the connecting part. The adjusting part is provided with a first guide part and a first guide mating part is provided on the first through hole. When the adjusting part is rotated for adjustment, it slides on the first guide mating part guided by the first guide part.

[0009] The limiting part includes a first limiting part disposed on one side of the first guide part, and the stopping part includes a first stopping part disposed on the first through hole. When the adjusting member is rotated in one direction for adjustment, it is limited by the first limiting part to the first stopping part of the first through hole in the direction of rotation.

[0010] The through hole also includes a second through hole provided on the cover plate, the limiting part also includes a second limiting part provided on the other side of the first guide part, and the stop part also includes a second stop part provided on the second through hole. When the adjusting member is rotated in the other direction for adjustment, it is limited by the second limiting part to the second stop part of the second through hole in the direction of rotation.

[0011] The adjusting component is provided with a second guide part, and the second through hole is provided with a second guide mating part. When the adjusting component is rotated for adjustment, it slides on the second guide mating part guided by the second guide part.

[0012] The adjusting part includes a threaded part provided on the adjusting member and a threaded mating part provided on the first through hole. The adjusting member is adjusted on the threaded mating part of the first through hole by rotating the threaded part.

[0013] The adjusting member is provided with an action part, and the tool acts on the action part to drive the adjusting member to rotate and adjust it on the through hole.

[0014] A drawer designed for this purpose includes a side panel and a front panel, with a front connector provided on the side panel. The drawer is characterized by further including the aforementioned adjustable connecting device, which is mounted on the front connector. The connecting device is connected to the front panel, and an adjustment groove is provided between the front connector and the side panel. The connector is adjusted left and right within the adjustment groove by the adjusting device, thereby achieving left and right position adjustment between the front panel and the side panel.

[0015] This invention provides two limiting fitting parts between the adjusting member and the through hole. When the adjusting member rotates in both clockwise and counterclockwise directions, the corresponding limiting fitting parts limit its rotational rotation and adjust it onto the through hole. This allows the adjusting member to slide vertically onto the through hole, changing the original vertical limiting method to a rotational (i.e., lateral) limiting method. The adjusting member is firmly held in place by the limiting fitting parts, and even if the screwdriver is turned too forcefully, the limiting fitting parts will not fail to maintain their position. The connecting part and the cover plate will not be pushed open, making the adjustment of the connecting device more reliable and improving the user experience. Attached Figure Description
