[0001] The present utility model relates to the technical field of furniture fittings, in particular a rotary and sliding mechanism for quick assembly and disassembly. State of the art

[0002] Corner rotating cabinets can effectively utilize the corner area of ​​a room and increase storage capacity. Conventional rotating cabinets typically consist of a fixed cabinet body that is anchored in the corner and a rotating cabinet body that is mounted within it. The rotating cabinet body uses mechanisms on its top and bottom to rotate and slide, allowing the user to store and retrieve items. However, these types of rotating cabinets present certain inconveniences during installation, as the cabinet body and the rotating mechanism are usually rigidly connected or secured with multiple screws. This leads to cumbersome workflows and lengthy assembly times during factory assembly, transport, and on-site installation at the customer's location.Especially during repairs or replacements to the rotating cabinet body, disassembly is a time-consuming process, negatively impacting the user experience and ease of maintenance. Therefore, there is an urgent need for a rotating and sliding mechanism that allows for quick and reliable assembly and disassembly of the rotating cabinet body.

Detailed description

[0014] With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig.Section 5 of the present utility model provides a rotating and sliding mechanism for quick assembly and disassembly. The rotating and sliding mechanism 30 is typically arranged in pairs between the fixing cabinet body 10 and the rotating cabinet body 20, so that the rotating cabinet body 20 can both rotate relative to the fixing cabinet body 10 and be moved to a certain extent in order to partially protrude when opened and to facilitate the storage and removal of items.

[0015] The rotary and sliding mechanism 30 comprises a fixing plate 31, a rotating plate 32, and a positioning element 33. The fixing plate 31 is attached to the inner walls of the top and bottom of the fixing cabinet body 10 by means of screws or the like. The rotating plate 32 is connected to the fixing plate 31 by means of integrated, known structures such as slide rails, slide blocks, cams, and the like, to enable a combined movement of horizontal displacement and rotation about a vertical axis. The positioning element 33 is an elongated rod body that is fixedly mounted by means of screws at the corresponding positions on the top and bottom of the rotating cabinet body 20.

[0016] A positioning groove 321, extending along both ends of the longitudinal axis of the rotary plate 32, is formed in the plate surface. The cross-sectional shape of the positioning element 33 is adapted to the positioning groove 321 and can be inserted or withdrawn along the positioning groove 321.

[0017] To achieve rapid locking, an elastic detent assembly 34 is arranged in the positioning groove 321. This assembly mainly comprises a detent block 341 and a return spring 342. A movement groove 322, connected to the positioning groove 321, is formed in the rotary plate 32, with the detent block 341 rotatably mounted in the movement groove 322 by means of a pivot axis (not shown in the figure). The pivot axis (not shown in the figure) forms the pivot point of the detent block 341.

[0018] The detent block 341 preferably has a lever structure, with a detent projection 343 and a grip section 344 formed on each of the two side faces of one end. The return spring 342 is preferably a torsion spring, which is mounted in a specially provided spring retaining section 323 within the movement groove 322. A through groove 345 is formed in the detent block 341 along its thickness direction. During assembly, one end of the torsion spring engages in this through groove 345, while the other end is fixed to the side wall of the spring retaining section 323. In this way, the torsion spring always exerts a torque on the detent block 341, which gives it a tendency to rotate about the axis of rotation in the direction of the positioning groove 321, so that the detent projection 343 tends to protrude inwards.

[0019] Two symmetrically arranged locking grooves 331 are formed in the side wall of the positioning element 33, the shape of which is adapted to the locking projection 343. To facilitate insertion and ensure reliable locking, the edges of the locking projection 343 and the locking grooves 331 are designed as inclined surfaces. In addition, a guide inclined surface 332 is formed at the insertion end of the positioning element 33.

[0020] Assembly and locking process: When the rotating cabinet body 20 is to be mounted, the cabinet body is lifted so that the positioning elements 33 on its top and bottom are aligned with the positioning grooves 321 of the upper and lower rotating plates 32, and then inserted horizontally. The guide inclined surface 332 at the end of the positioning element 33 first contacts the detent projection 343 of the detent block 341 and presses it together, overcomes the torsional force of the return spring 342, and forces the detent block 341 to rotate outwards and release the passage. When the positioning element 33 is pushed further into the predetermined position, i.e., when the detent grooves 331 on both sides are aligned with the detent projections 343, the detent block 341 rapidly rotates back inwards under the torsional force of the return spring 342, so that the detent projections 343 engage in the detent grooves 331 and the positioning element 33 (i.e.,The rotating cabinet body 20) is securely locked to the rotating plate 32. The continuous design of the positioning groove 321 allows locking by insertion from both ends, thus offering flexible mounting direction.

[0021] Disassembly and unlocking procedure: If the rotating cabinet body 20 is to be disassembled (for example, for repair or replacement), the user simply needs to pull or actuate the exposed handle section 344 on the locking block 341 outwards by hand or with a tool. Due to the lever principle, actuating the handle section 344 effortlessly overcomes the torsional force of the return spring 342, causing the locking block 341 to rotate outwards about its axis of rotation and the locking projection 343 to fully disengage from the locking groove 331. At this moment, the locking mechanism of the positioning element 33 is released, and the rotating cabinet body 20, together with the positioning element 33, can be pulled horizontally out of the positioning groove 321, thus completing the quick disassembly.
