Description

Technical Field

[0001] The utility model relates to the field of cabinets, in particular to a lifting cabinet with a steel cable anti-loosening function. Background Art

[0002] Automation and intelligence are currently key development trends in home furnishing products. In existing automated furniture, liftable cabinets are designed. By placing the cabinets at a high level, they are lowered only when items are needed, and then raised back up again. This improves space utilization and provides greater flexibility and convenience. A common lifting method for liftable cabinets involves using a winch to retract and release a steel cable. The winch raises the cabinet when the cable is reeled in; when the cable is released, the cabinet descends under its own weight. However, if the cabinet is subjected to an external upward force during the lifting process, the normally taut cable will slacken. This slack and bent cable can cause it to deviate and become stuck. If the cable deviates and becomes stuck in the cabinet, it not only hinders the operation of the winch but can also damage the cabinet's structure. For example, a stuck cable can overload the winch motor, causing malfunction or damage. Furthermore, compression and friction from the cable can cause wear and deformation on the cabinet's panels and connectors. Therefore, solving the problem of loose steel cables and further causing subsequent safety problems is a technical problem that needs to be solved urgently in the design of existing lifting cabinets.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0037] The following is combined with Figures 1 to 5 The technical solution of the utility model is further illustrated through specific implementation methods.

[0038] A lifting cabinet with a steel cable anti-loosening function, comprising an outer cabinet body 1, an inner cabinet body 2, a hoist 3, a steel cable 4, an anti-loosening structure 5 and an electric control board 6, wherein the hoist 3 and the anti-loosening structure 5 are electrically connected to the electric control board 6 respectively;

[0039] The hoist 3 is installed on the inner top wall of the outer cabinet 1, and the inner cabinet 2 is located on the inner side of the outer cabinet 1. The two ends of the steel cable 4 are respectively connected to the hoist 3 and the inner cabinet 2. The hoist 3 is used to retract and extend the steel cable 4 to drive the inner cabinet 2 to rise and fall through the bottom opening of the outer cabinet 1;

[0040] The anti-loosening structure 5 is installed on the inner top wall of the outer cabinet 1, and the steel cable 4 extends through the anti-loosening structure 5. When the steel cable 4 is in a relaxed state, the anti-loosening structure 5 is triggered, and the electric control board 6 controls the winch 3 to stop operating.

[0041] The present invention proposes a lifting cabinet with a steel cable anti-loosening function. By installing an anti-loosening structure 5 and an electric control board 6 on the inner top wall of the outer cabinet body 1, timely detection and prevention of the deviation of the steel cable 4 can be achieved. Specifically, the lifting cabinet of the present invention includes an outer cabinet body 1, an inner cabinet body 2, a winch 3, a steel cable 4, an anti-loosening structure 5 and an electric control board 6. The winch 3 and the anti-loosening structure 5 are both electrically connected to the electric control board to form a complete control system. The winch 3 is installed on the inner top wall of the outer cabinet body 1 to control the retraction and extension of the steel cable 4. One end of the steel cable 4 is connected to the winch 3, and the other end is connected to the inner cabinet body 2 located on the inner side of the outer cabinet body 1. When the cabinet needs to be used, the winch 3 drives the inner cabinet body 2 to rise and fall through the bottom opening of the outer cabinet body 1 by controlling the retraction and extension of the steel cable 4, so as to realize the opening and closing of the cabinet. To prevent the steel cable 4 from deviating, an anti-loosening structure 5 is cleverly installed on the inner top wall of the outer cabinet body 1. Under normal use, the steel cable 4 passes through the anti-loosening structure 5, keeping it in a normally open or normally closed state. This ensures that if the steel cable 4 slackens and deviates, the anti-loosening structure 5 will immediately trigger the switch from the normally open state to the closed state (or from the normally closed state to the open state), and then control the winch 3 to stop operation through the electronic control panel 6. This instant feedback and shutdown mechanism prevents further relaxation and deviation of the steel cable 4 and possible jamming, thereby ensuring the stability and safety of the lifting cabinet.

[0042] The technical solution of this utility model offers significant advantages over existing technologies. First, the provision of the anti-loosening structure 5 allows for timely detection of loose wire rope 4 problems, preventing the wire rope 4 from becoming stuck due to continued loosening and deviation. Second, the coordinated control of the electric control panel 6 and the hoist 3 ensures immediate shutdown when loose wire rope 4 occurs, effectively preventing damage to the equipment caused by loose wire rope 4, deviation, or jamming.

[0043] Furthermore, the anti-loosening structure 5 includes a mounting base 51, a micro switch 52 and a sensor plate 53;

[0044] The micro switch 52 is mounted on the inner top wall of the outer cabinet 1 via the mounting base 51. The middle portion of the sensing plate 53 is hinged to the housing of the micro switch 52 via a hinge shaft. The two ends of the sensing plate 53 are respectively a sensing portion 531 and a trigger portion 532. The sensing portion 531 is provided with a steel cable through hole 5310. The steel cable 4 is horizontally passed through the steel cable through hole 5310. The trigger portion 532 corresponds to the contact of the micro switch 52.

[0045] The micro switch 52 is electrically connected to the electric control board 6 .

[0046] The anti-loosening structure 5 adopts a design in which the sensing plate 53, the micro switch 52 and the mounting seat 51 cooperate with each other, so that a simple mechanical structure can realize sensitive detection of the deviation of the steel cable. The sensing plate 53 is connected to the housing of the micro switch 52 through a hinge shaft, and the sensing plate 53 is divided into a sensing part 531 and a triggering part 532. The sensing part 531 is provided with a steel cable through hole 5310 so that the steel cable 4 can pass horizontally, and the triggering part 532 corresponds to the contact of the micro switch 52. When the steel cable 4 deviates, the sensing part 531 will drive the sensing plate 53 to rotate, and the triggering part 532 will touch the contact of the micro switch 52, thereby sending a signal through the micro switch 52 to control the electric control panel to stop the operation of the winch, prevent the steel cable from continuing to deviate, and ensure the stable and safe operation of the lifting cabinet.

[0047] Furthermore, a hinge portion is provided in the middle of the sensing plate 53, and the hinge portion is two hinge arms 533;

[0048] The hinged arms 533 are perpendicular to the sensing plate 53 , and the two hinged arms 533 correspond to each other in the upper and lower directions and are respectively clamped on the upper and lower end surfaces of the housing of the micro switch 52 .

[0049] By providing two hinged arms 533 perpendicular to the sensing plate 53 as hinged portions, and respectively engaging the upper and lower end surfaces of the microswitch 52 housing, this design enhances the stability of the connection between the sensing plate 53 and the microswitch 52. Even under external forces, the sensing plate 53 is unlikely to shake or fall off, thereby ensuring the reliability and durability of the anti-loosening structure.

[0050] In addition, the hinge arrangement enables the sensing plate 53 to flexibly respond to the deflection of the cable 4. When the cable 4 deflects and drives the sensing portion 531, the sensing plate 53 rotates relative to the hinge axis, and the triggering portion 532 triggers the micro switch 52, thereby detecting the deflection of the cable 4.

[0051] Furthermore, in order to ensure the reliable operation of the hinged part, an elastic element can be added at the connection between the hinged part and the sensing plate 53, so that the sensing plate 53 maintains its initial position in the non-working state. When the steel cable 4 deflects to a certain extent, it touches the sensing part 531 and pushes the sensing plate 53 to move, thereby triggering the micro switch.

[0052] Furthermore, the sensing portion 531 includes two mounting arms 5311 and a 匚-shaped enclosure frame 5312;

[0053] The mounting arms 5311 are perpendicular to the sensing plate 53. The two mounting arms 5311 are respectively provided at the upper and lower ends of the sensing plate 53. The 匚-shaped enclosure frame 5312 and the two mounting arms 5311 enclose the steel cable through hole 5310 extending therethrough.

[0054] The hinge portion and the sensing portion 531 are respectively disposed at the front and rear sides of the sensing plate 53 .

[0055] The sensing unit 531, formed by the two mounting arms 5311 and the 匚-shaped enclosure frame 5312, forms a cable hole 5310 extending horizontally therethrough, allowing the cable 4 to pass smoothly through the sensing unit 531. During operation, since the cable 4 is enclosed within the cable hole 5310, if the cable 4 deflects, the action of the sensing unit 531 is transmitted to the trigger unit 532, triggering the microswitch 52 and transmitting a signal to the electronic control board 6. Upon receiving the signal, the electronic control board 6 immediately controls the hoist 3 to stop operation, thereby preventing further cable deflection and ensuring the safe raising and lowering of the inner cabinet 2.

[0056] The mounting arms 5311 of the sensing portion 531 are fixed to the upper and lower ends of the sensing plate 53, the 匚-shaped enclosure frame 5312 is sandwiched between the two mounting arms 5311, and the cable through hole 5310 is located at the center of the 匚-shaped enclosure frame 5312. This arrangement ensures that the cable 4 maintains a stable trajectory when passing through the sensing portion 531.

[0057] The hinge and the sensing portion 531 are respectively arranged on the front and rear sides of the sensing plate 53. This layout not only makes the entire anti-loosening structure 5 more compact, but also avoids mutual interference between the hinge and the sensing portion 531. This design optimizes space utilization and makes the internal structure of the lifting cabinet more reasonable.

[0058] The specific design of the sensing portion 531 simplifies installation. During installation, there's no need to disassemble the steel cable 4. Simply align the end of the sensing plate 53 with the mounting arm 5311, connect the ⌚-shaped enclosure frame 5312 to the mounting arm 5311, and then enclose the steel cable 4 within the cable through-hole 5310. This design also facilitates subsequent maintenance and repair, reducing maintenance costs.

[0059] Furthermore, the sensing portion 531 further includes a roller 5313 and a roller shaft 5314;

[0060] The two mounting arms 5311, the upper enclosing plate 53121 of the 匚-shaped enclosing frame 5312 and the lower enclosing plate 53122 of the 匚-shaped enclosing frame 5312 are respectively provided with mounting holes, and the roller shaft 5314 vertically passes through the mounting holes of the two mounting arms 5311 and the 匚-shaped enclosing frame 5312, and the roller 5313 is installed on the rear side of the steel cable through hole 5310 through the roller shaft 5314.

[0061] By installing roller 5313 behind cable hole 5310, cable 4 experiences rolling friction when in contact with roller 5313 during retraction and extension, significantly reducing wear on cable 4 compared to sliding friction. This not only extends the service life of cable 4 but also reduces the risk of failure and safety hazards caused by wear.

[0062] Furthermore, the sensing portion 531 further includes two positioning blocks 5315 , which are respectively provided on the two mounting arms 5311 and located outside the mounting arms 5311 ;

[0063] Positioning openings 53120 are provided at the rear ends of the upper enclosing plate 53121 and the lower enclosing plate 53122 , and the two positioning openings 53120 are respectively connected to the two positioning blocks 5315 .

[0064] Positioning blocks 5315 are provided on the outsides of the two mounting arms 5311, respectively. These blocks 5315 engage with positioning openings 53120 at the rear ends of the upper and lower enclosure plates 53121 and 53122, significantly enhancing the overall structural stability of the sensing unit 531. The coordination between positioning blocks 5315 and positioning openings 53120 prevents deformation or displacement of the mounting arms 5311 when subjected to force, thereby ensuring the accuracy and stability of the cable through-hole 5310.

[0065] The design of positioning block 5315 and positioning opening 53120 allows for more precise installation of sensor unit 531. During installation, simply align positioning block 5315 with positioning opening 53120 and secure it, eliminating the need for complex adjustments and calibration. This not only improves installation efficiency but also reduces the risk of failures caused by improper installation.

[0066] Furthermore, the number of the steel cables 4 and the anti-loosening structure 5 is two respectively;

[0067] The two anti-loosening structures 5 are respectively arranged on the left and right sides of the winch 3, one end of the two steel cables 4 is connected to the winch 3, and the other ends of the two steel cables 4 pass through the two anti-loosening structures 5 and are connected to the left and right sides of the inner cabinet 2.

[0068] The stability of the lifting cabinet is enhanced by providing two steel cables 4 and two anti-loosening structures 5. One end of each steel cable 4 is connected to the winch 3, and the other end passes through the corresponding anti-loosening structure 5 and connects to the left and right sides of the inner cabinet 2. This effectively prevents the inner cabinet 2 from shifting during the lifting process. The design of the two steel cables 4 and the two anti-loosening structures 5 not only balances the lifting force and improves the lifting stability, but also promptly senses and triggers the anti-loosening structure 5 when the steel cables 4 shift, controlling the winch 3 to stop operation through the electronic control panel 6, ensuring the safety of the lifting process.

[0069] In practice, this design isn't limited to just one implementation. For example, the anti-loosening structure 5 could employ various sensor technologies, such as photoelectric or magnetic sensors, instead of micro switches to enhance detection accuracy. Furthermore, the steel cable could be made of a variety of materials, such as stainless steel or iron, depending on specific needs. Each anti-loosening structure can be customized based on actual usage requirements, further enhancing the system's flexibility and adaptability.

[0070] Furthermore, it also includes two guide structures 7, which are respectively arranged on the left and right sides of the winch 3. The two steel cables 4 are respectively guided by the guide structures 7 on both sides and then connected to the inner cabinet 2.

[0071] The two steel cables 4 can move more accurately along the predetermined path under the guidance of the two guide structures 7. The design of the guide structures 7 makes it difficult for the steel cables 4 to deviate from the normal path during the lifting process, thereby improving the guidance and stability of the steel cable movement.

[0072] Furthermore, the guide structure 7 includes a mounting frame 71 and a guide wheel 72;

[0073] The mounting frame 71 is mounted on the inner top wall of the outer cabinet 1 , the guide wheel 72 is rotatably mounted on the mounting frame 71 , and the steel cable 4 is wound around the outer circumference of the guide wheel 72 .

[0074] By providing the mounting bracket 71 and the guide wheel 72, the guide structure 7 can more effectively guide the movement path of the steel cable 4. The steel cable 4 is wrapped around the outer periphery of the guide wheel 72, so that the steel cable can move smoothly along the contour of the guide wheel 72 during the lifting process, reducing the shaking and deviation of the steel cable 4 and improving the accuracy and stability of the guidance.

[0075] The guide wheel 72 is rotatably mounted to reduce friction between the steel cable 4 and the guide structure 7 when the steel cable 4 passes through. This design can reduce the wear of the steel cable 4, extend the service life of the steel cable 4, and also reduce noise and energy loss caused by friction.

[0076] At the same time, the guide structure 7 takes into account the utilization of space and the compactness of the structure. The mounting frame 71 is mounted on the inner top wall of the outer cabinet 1, and the guide wheel 72 is compactly mounted on the mounting frame 71, which can reduce the space occupied inside the lifting cabinet and make the overall structure more compact and reasonable.

[0077] The introduction of the guide structure 7 also improves the safety of the lift cabinet by optimizing the guiding performance of the steel cable 4 and reducing friction and wear. This reduces the potential for malfunctions and safety hazards caused by the steel cable deviating from its normal path or unstable lifting, providing users with a safer and more reliable lift cabinet experience.

[0078] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
