Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing, and in particular to a limiting device. Background Technology

[0002] In daily life, many cabinet doors are connected by hinges. In some situations, users need to fix the cabinet door at a certain angle, but due to airflow and other factors, it is difficult to maintain a fixed opening angle. Therefore, some cabinets often have limiting devices on the doors to fix them. Conventional door limiting devices use a combination of a sliding track and a limiting rod. When the limiting rod slides to the limiting part, the opening angle of the door panel is fixed. However, this design limits the angle to a single angle and cannot achieve multi-angle limiting. Utility Model Content

[0003] The purpose of this utility model is to provide a door panel limiting device that can limit movement at multiple angles.

[0004] To achieve the above objectives, this utility model proposes a limiting device for use on a cabinet to limit the movement of the cabinet door. It includes a limiting unit and a limiting rod. The limiting unit is fixedly connected to the cabinet door. One end of the limiting rod has a connector for insertion into the limiting unit, and the other end is rotatably connected to the cabinet body. The limiting unit includes an elastic component that applies a spring force to the connector in the horizontal direction to achieve elastic limiting of the limiting rod by the limiting unit.

[0005] The elastic component has a plurality of accommodating portions spaced apart along its length. The accommodating portions are used to accommodate the plug-in portion. There is a sliding channel between each pair of adjacent accommodating portions. The sliding channel confines the plug-in portion within the accommodating portion. The sliding channel is elastically deformable. During the opening and closing of the cabinet door, the elastic deformation of the sliding channel causes the plug-in portion to move between different accommodating portions.

[0006] Preferably, the elastic component includes two wavy spring pieces, each spring piece having a plurality of recessed structures spaced apart along its length, and the two spring pieces are combined together so that the recessed structures on the two spring pieces correspond one-to-one to form a receiving portion.

[0007] Preferably, the limiting unit further includes a housing, with an elastic component disposed inside the housing, and a waist hole is provided on the side of the housing corresponding to the insertion of the limiting rod into the elastic component.

[0008] Preferably, the cabinet includes a cabinet door and a cabinet body. A limiting unit is disposed on the cabinet door. The other end of the limiting rod away from the plug-in part is a rotating part connected to the cabinet body. The rotating part is rotatably connected to the cabinet body. The plug-in part and the rotating part are connected by a connecting part.

[0009] Preferably, the insertion part and the rotating part are formed by bending the two ends of the limiting rod in the vertical direction to the same side, and an installation hole is provided on the cabinet to insert the rotating part into the installation hole.

[0010] The beneficial effects of this utility model are as follows:

[0011] The limiting device of this utility model uses a limiting unit and a limiting rod to cooperate. The insertion part of one end of the limiting rod is inserted into the limiting unit. Force is applied to the limiting rod to allow it to slide horizontally within the limiting unit. The limiting unit contains an elastic component with multiple accommodating portions spaced apart along its length. These accommodating portions accommodate the insertion part, and a sliding channel is provided between adjacent accommodating portions. The sliding channel is elastically deformable; during the opening and closing of the cabinet door, the elastic deformation of the sliding channel allows the insertion part to move between different accommodating portions. In use, the user can push the limiting rod to a suitable position within the elastic component, placing the insertion part of the limiting rod in the accommodating portion. The elasticity of the sliding channel next to the accommodating portion provides elastic limiting of the limiting rod, fixing the opening angle of the door panel and achieving multi-angle limiting of the door panel.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] See Figure 1-5 As shown in the preferred embodiment of this utility model, a limiting device is proposed for limiting the opening angle of a cabinet door when installed on a cabinet. The limiting device includes a limiting unit 1 and a limiting rod 2. The limiting unit 1 is fixedly connected to the cabinet door 4. One end of the limiting rod 2 is a plug-in portion 21 that inserts into the limiting unit 1, and the other end of the limiting rod 2 away from the limiting unit 1 is a rotating portion 22 that is rotatably connected to the cabinet body 3. The plug-in portion 21 and the rotating portion 22 are connected by a connecting portion 23, which props the cabinet door 4 apart from the cabinet body 3 by a certain distance. The limiting unit 1 includes an elastic component 11. The elastic component 11 has N accommodating portions 15 spaced apart along its length for accommodating the plug-in portions 21, where N is greater than or equal to 2. A sliding channel 14 is provided between every two adjacent accommodating portions 15, which confines the plug-in portion 21 within the accommodating portion 15. The sliding channel 14 is elastically deformable. The insertion part 21 is inserted into the elastic component 11. During the opening and closing of the cabinet door 4, the rotation of the cabinet door 4 exerts a force on the limiting rod 2, causing the insertion part 21 to slide horizontally within the elastic component 11. The force of the cabinet door 4's rotation causes the sliding channel 14 to elastically deform, allowing the insertion part 21 to move between different receiving parts 15. The limiting unit 1 can also be fixedly connected to the cabinet body 3. The insertion part 21 of the limiting rod 2 is inserted into the limiting unit 1, and the rotating part 22 of the limiting rod 2 is rotatably connected to the cabinet door 4, allowing the connecting part 23 of the limiting rod 2 to rotate horizontally.

[0020] In this embodiment, the elastic component 11 includes two wavy spring pieces 111. Each spring piece 111 has multiple recessed structures 112 spaced apart along its length. The two spring pieces 111 are combined so that the recessed structures 112 on the two spring pieces 111 correspond one-to-one to form receiving portions 15, and a sliding channel 14 is formed between two adjacent receiving portions 15. The width of the sliding channel 14 is smaller than the width of the insertion portion 21, so as to achieve elastic limiting of the insertion portion 21 that is inserted into the receiving portion 15. When force is applied to the limiting rod 2, the insertion portion 21 can slide in the horizontal direction of the limiting unit 1, that is, slide between the N receiving portions 15. The sliding channel 14 will undergo elastic deformation to allow the insertion portion 21 to pass through. During use, the user can open the cabinet door 4 to a suitable position as needed. The limiting rod 2 will automatically slide to the appropriate position in the elastic component 11, and place the insertion part 21 in the receiving part 15. The elasticity of the sliding channel 14 next to the receiving part 15 will achieve elastic limiting of the limiting rod 2, fixing the opening angle of the cabinet door 4, and realizing the multi-angle limiting of the cabinet door by the limiting device.

[0021] In other embodiments, the elastic component 11 may also consist of two limiting plates. These two limiting plates form a channel within the limiting unit, allowing only the insertion part to slide within it. Multiple elastic elements protruding towards the channel are spaced apart on the limiting plates, dividing the channel into N receiving portions. This achieves elastic limiting of the insertion part by the elastic elements. When the insertion part passes through an elastic element, the elastic element retracts into the limiting plate. After the insertion part slides past, the elastic element pops out towards the channel. When the user opens the cabinet door to a suitable position, the limiting rod adaptively slides to the appropriate position within the elastic component, placing the insertion part in the receiving portion. The elasticity of the sliding channel next to the receiving portion achieves elastic limiting of the limiting rod, fixing the opening angle of the cabinet door and realizing multi-angle limiting of the cabinet door by the limiting device.

[0022] In this embodiment, the insertion part 21 and the rotating part 22 of the limiting rod 2 are formed by bending both ends of the limiting rod 2 in the vertical direction towards the same side. A mounting hole 31 is provided on the cabinet body 3, and the rotating part 22 is inserted into the mounting hole 31. The limiting unit 1 is fixed to the inside of the cabinet door 4, and the insertion part 21 is inserted into the limiting unit 1. The rotating part 22 rotates in the mounting hole 31 to achieve a rotatable connection between the rotating part 22 and the cabinet body 3, satisfying the multi-angle limiting of the cabinet door when it is pulled. Of course, in other embodiments, the rotating part can also be a plate-like structure with holes, which is bolted to the mounting hole to achieve a rotatable connection between the rotating part and the cabinet body.

[0023] To prevent the elastic component 11 from being exposed and easily damaged, the limiting unit 1 also includes a housing 12, in which the elastic component 11 is disposed. On the side of the housing 12 opposite to the insertion of the limiting rod 2 into the elastic component 11, there is a waist hole 13 for the insertion part 21 to slide in the limiting unit 1.

[0024] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
