Description

Technical Field

[0001] This utility model belongs to the field of furniture technology, specifically relating to a lifting and rotating device for furniture products. Background Technology

[0002] Furniture refers to a broad category of appliances and facilities essential for human beings to maintain normal life, engage in production practices, and carry out social activities. Furniture has also continuously evolved and innovated with the times, resulting in a wide variety of categories, materials, types, and uses. Traditional furniture often employs a fixed, non-adjustable structure. However, with the development of the office furniture industry, as a branch of the furniture sector, it is also necessary to update its designs to meet actual market and customer needs.

[0003] Chinese patent document CN217039298U discloses an automatically height-adjustable furniture cabinet, belonging to the field of cabinet technology. This automatically height-adjustable furniture cabinet includes a lifting assembly and a cabinet body. The lifting assembly includes a base plate, a motor, a double-ended screw, a first support rod, and a second support rod. The motor is connected to one side of the base plate, and the double-ended screw is rotatably connected to the upper surface of the base plate. One end of the double-ended screw is fixedly connected to the output end of the motor. In this process, the motor drives the double-ended screw to rotate, which in turn drives the first and second support rods to rotate, gradually lifting the cabinet body and raising its height. This eliminates the need for bending or squatting when taking items from the bottom of the cabinet, which is very convenient for people with leg problems or back ailments.

[0004] The furniture cabinet described in the aforementioned patent document uses a scissor lift for raising and lowering. Due to structural gaps in the lifting components, the lifting platform sways significantly during the lifting process, and the platform also tilts, posing a certain safety hazard.

Detailed Implementation

[0018] like Figures 1-5As shown, this embodiment provides a lifting and rotating device for furniture products, including a rotating base 1, a lifting base 2, a rotating drive mechanism, a guide mechanism, a lead screw drive mechanism, and a sensor switch. The rotating base 1 is connected to the movable furniture part 3, such as a support platform, and can place items to be displayed or retrieved on the support platform according to different application scenarios. The rotating base 1 can rotate together with the movable furniture part 3 for convenient display or retrieval of items. The rotating base 1 and the lifting base 2 are rotatably coupled, and a conductive slip ring 4 is provided between the rotating base 1 and the lifting base 2 to facilitate power supply to the electrical appliances on the movable furniture part 3 and prevent the wiring from becoming tangled or broken when the movable furniture part 3 rotates. The rotating drive mechanism is used to drive the rotating base 1 to rotate relative to the lifting base 2, thereby realizing the rotation function of the movable furniture part 3.

[0019] The guide mechanism is located between the lifting seat 2 and the furniture fixing component 5. The screw drive mechanism drives the lifting seat 2 to move up and down relative to the furniture fixing component 5, causing the furniture moving component 3 to move up and down along with the items. The induction switch is located on the lifting trajectory of the furniture moving component 3 and is used to control the screw drive mechanism to stop. The number of induction switches can be set according to actual needs; typically, two induction switches are used. When the furniture moving component 3 rises to its highest position, one induction switch is triggered, controlling the screw drive mechanism to stop, and the furniture moving component 3 stops rising. When the furniture moving component 3 descends to its lowest position, the other induction switch is triggered, controlling the screw drive mechanism to stop, and the furniture moving component 3 stops descending, thus protecting the screw drive mechanism.

[0020] This invention utilizes a lead screw drive mechanism to move the furniture's movable part 3 up and down, while a guide mechanism guides the movement of the furniture's movable part 3, ensuring smooth lifting and lowering and preventing items on it from shaking and falling. Furthermore, the furniture's movable part 3 has a rotation function, allowing for full display of items. This invention features a simple structure, convenient installation, stable operation, high load-bearing capacity, reliable operation, strong stability, and high practicality.

[0021] In this embodiment, as Figure 2As shown, the lead screw drive mechanism includes a lead screw drive motor 6, a lead screw 7, and a lead screw slider 8. The output end of the lead screw drive motor 6 is connected to the lead screw 7. The lead screw 7 is equipped with a support frame 9, which is mounted on the furniture fixing component 5. The lead screw slider 8 is mounted on the lead screw 7 and is connected to the lifting seat 2. Preferably, both ends of the lifting seat 2 are connected to lead screw sliders 8, and each lead screw slider 8 is equipped with a lead screw 7. The lead screw 7 is a trapezoidal lead screw 7 to increase the lifting force. The lead screw drive motor 6 can be controlled using a control panel. Both lead screw drive motors 6 operate simultaneously to realize the lifting function of the furniture moving component 3. When the induction switch is triggered, both lead screw drive motors 6 stop operating simultaneously.

[0022] like Figure 1 As shown, the support frame 9 is provided with an electrical cover plate 10, and an electrical placement slot is provided below the electrical cover plate 10. Cables and power strips can be placed in the electrical placement slot and covered by the electrical cover plate 10.

[0023] In one specific implementation, such as Figure 2 As shown, the guiding mechanism includes a guide rail 11 and a guide slider 12 that cooperate with each other. The guide rail 11 is mounted on the support frame 9, and the guide slider 12 is connected to the lifting seat 2. Both the top and bottom ends of the guide rail 11 are equipped with inductive switches, which are used to control the screw drive motor 6 to stop operating. Preferably, both ends of the lifting seat 2 are connected to guide sliders 12, and each guide slider 12 is equipped with a guide rail 11. This utility model utilizes the screw drive motor 6 to drive the screw 7 to rotate, causing the screw slider 8 to move the lifting seat 2 up and down. Simultaneously, with the cooperation of the guide rail 11 and the guide slider 12, the smooth lifting function of the furniture's moving parts 3 is achieved.

[0024] In this embodiment, as Figure 3 As shown, the rotary drive mechanism includes a rotary drive motor 13, a gear 14, and a gear ring 15. The output end of the rotary drive motor 13 is connected to the gear 14, and the gear 14 meshes with the gear ring 15. The gear ring 15 is connected to the rotating seat 1. The gear 14 is located inside the gear ring 15. The rotary drive motor 13 drives the gear ring 15 to rotate through the gear 14, causing the rotating seat 1 to rotate along with the furniture moving part 3. Both the rotary drive motor 13 and the lead screw drive motor 6 are controlled by a control panel. When the current of the rotary drive motor 13 and the lead screw drive motor 6 exceeds the safe current, the control panel stops the rotary drive motor 13 and the lead screw drive motor 6 from working. Since the control panel, motor, and inductive switch are all mature technologies, they will not be described in detail.

[0025] As an example, such as Figure 1As shown, the movable furniture component 3 includes an upper panel 16, a lower panel 17, a connecting shaft 18, and several partition plates 19. The two ends of the connecting shaft 18 are connected to the upper panel 16 and the lower panel 17, respectively. One side of each partition plate 19 is connected to the connecting shaft 18, and the upper and lower ends of each partition plate 19 are connected to the upper panel 16 and the lower panel 17, respectively. Both the upper panel 16 and the lower panel 17 are disc-shaped. The bottom of the lower panel 17 is connected to the rotating base 1. Items can be placed on top of the upper panel 16 or on the lower panel 17.

[0026] like Figure 4 and Figure 5 As shown, the furniture fixing component 5 includes a fixing frame with a lifting port for the movable furniture component 3 to move up and down. The fixing frame has internal storage space, allowing the movable furniture component 3 to descend and be concealed within this space. Infrared sensors, light gratings, and AGV anti-pinch devices can be installed around the lifting port as needed to provide multiple layers of protection.

[0027] Compared with the prior art, the present invention has the following advantages: 1. The structure is simple and versatile. The number of components such as the trapezoidal lead screw 7, motor and guide rail 11 can be selectively set according to different usage scenarios to improve the lifting force.

[0028] 2. A conductive slip ring 4 is provided between the rotating seat 1 and the lifting seat 2 to avoid the problem of wire entanglement and breakage when the rotating seat 1 rotates.

[0029] 3. It occupies little space, is lightweight, and is simple, quick, and convenient to install.

[0030] 4. It operates smoothly, has a high load-bearing capacity, no shaking, low noise, long service life, and low maintenance costs.
