Description

Technical Field

[0001] The utility model relates to a cabinet lifting device, in particular to an electric lifting cabinet. Background Art

[0002] Cabinets are widely used in home and commercial environments, especially in kitchens and offices. In order to improve space utilization efficiency and user convenience, the design of cabinets has gradually developed towards adjustable height, among which the design of electric cabinet lifting mechanism has become the key to improving the functionality of cabinets. Traditionally, this type of lifting mechanism mainly relies on a wire winch system to achieve the lifting of shelves. This system has certain advantages, such as relatively low cost and relatively simple installation and maintenance. However, the wire winch system has the following shortcomings in actual use, which limit its application scope and user experience in modern home design.

[0003] 1. The wire hoist mechanism relies on one or more motors to pull the cabinet shelves through the wire rope for lifting. Since the wire rope may have inconsistent tension when wound on different pulleys, it is easy to cause the lifting and lowering of the two sides to be asynchronous. This asynchrony will cause the cabinet to sway or tilt during the lifting process, and in severe cases, it may even cause items to slip out of the cabinet or be damaged.

[0004] 2. The descending process of the traditional mechanism mainly relies on the deadweight of the cabinet, which requires that the cabinet must have sufficient weight to ensure the continuity and stability of the descent. However, in actual use, if the items in the cabinet are light or the weight of the items loaded on the left and right sides is uneven, it may cause stagnation or inconsistent speed during descent, further affecting the use effect and safety.

[0005] 3. The wire rope is prone to wear, deformation and even breakage during long-term use. These problems not only require regular inspection and replacement of the wire rope, increasing maintenance costs, but also affect the safety and reliability of the entire mechanism. Therefore, it is necessary to make further improvements. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide an electric lifting cabinet with a simple structure, easy to use, complete synchronization of the left and right sides during the lifting process of the cabinet, and significantly improving the stability of its movement and the reliability of the overall structure.

[0007] The purpose of the utility model is achieved in the following way: an electric lifting cabinet, which includes a guide mechanism installed symmetrically on the inside of the cabinet, the guide mechanism is driven to move by a power mechanism, and the lifting layer is connected to the guide mechanism and driven to move up and down by the guide mechanism;

[0008] The guide mechanism comprises a chain track plate fixed on the cabinet, sprockets are rotatably mounted at the upper and lower ends of the chain track plate, a transmission chain is mounted on the two sprockets, and one of the sprockets is connected to the power mechanism and driven to rotate by the power mechanism;

[0009] Furthermore, a slide plate is connected to the transmission chain, and the slide plate extends out of the chain track plate and is connected to the lifting layer plate.

[0010] Furthermore: the chain rail plate is a hollow rectangular shape, and a guide rail groove is provided on the side facing the lifting layer plate. A guide block is provided on the side wall of the slide plate. The guide block extends into the guide rail groove to slide and is connected to the lifting layer plate.

[0011] Furthermore: the inner side of the chain track plate is covered with a decorative plate, the outer side of the decorative plate is connected to the guide block, and the inner side is connected to the lifting layer plate.

[0012] Furthermore: the lifting layer plate is provided with several layers, which are evenly distributed and installed on the decorative plate.

[0013] Furthermore: the power mechanism is a reduction motor box, which drives the synchronization rod to move, and the two ends of the synchronization rod are respectively connected to the sprockets of the left and right sets of guide mechanisms to drive them to move.

[0014] Furthermore: a plurality of linkage teeth extend from the side wall of the slide plate, and the linkage teeth are inserted into the links of the transmission chain to be connected thereto.

[0015] The beneficial effects of the utility model are: 1. Simple structure, low production cost and improved market competitiveness.

[0016] 2. The utility model adopts a left-right symmetrical guide mechanism, which includes a chain track plate and a sprocket system, which are driven by a reduction motor box. Through this design, not only the power transmission efficiency of the mechanism is improved, but also the complete synchronization of the left and right sides during the lifting process is ensured. This synchronization significantly reduces the risk of jamming and cabinet tilting, and improves the overall operational stability and safety.

[0017] 3. The structure of chain rail plate and transmission chain provides higher durability and less maintenance requirements than the traditional wire winch mechanism. The combination of sprocket and chain is less prone to wear or breakage than wire rope, which greatly increases the service life and reliability of the overall equipment.

[0018] 4. The slide plate design on the transmission chain enables the lifting layer to move up and down smoothly along the chain track plate. The guide block in the slide plate design is further inserted into the guide rail groove to ensure the guiding accuracy and prevent swaying during the lifting process. In addition, this mechanism does not rely on the weight of the cabinet to descend, and can maintain the consistency and smoothness of lifting regardless of whether the weight of the cabinet is uniform.

[0027] The utility model is further described in detail below with reference to the accompanying drawings. An electric lifting cabinet comprises a guide mechanism symmetrically installed on the inner side of the cabinet, the guide mechanism is driven to move by a power mechanism, and a lifting plate 1 is connected to the guide mechanism and driven to move up and down by the guide mechanism;

[0028] The guide mechanism includes a chain track plate 2 fixed on the cabinet 12, sprocket wheels 3 are rotatably mounted at the upper and lower ends of the chain track plate 2, and a transmission chain 4 is mounted on the two sprocket wheels 3. One of the sprocket wheels 3 is connected to the power mechanism and driven to rotate by the power mechanism.

[0029] The transmission chain 4 is also connected with a slide plate 5 , which extends out of the chain track plate 2 and is connected with the lifting layer plate 1 .

[0030] In one of the embodiments: the chain rail plate 2 is a hollow rectangular shape, and a guide rail groove 6 is provided on the side facing the lifting layer plate 1. A guide block 7 is provided on the side wall of the slide plate 5. The guide block 7 extends into the guide rail groove 6 and slides, and is connected to the lifting layer plate 1.

[0031] In one of the embodiments: the inner side of the chain track plate 2 is covered with a decorative plate 8, the outer side of the decorative plate 8 is connected to the guide block 7, and the inner side is connected to the lifting layer plate 1.

[0032] In one embodiment, the lifting layer plate 1 is provided with a plurality of layers, which are evenly distributed and installed on the decorative plate 8.

[0033] In one embodiment, the power mechanism is a reduction motor box 9, which drives the synchronization rod 10 to move. The two ends of the synchronization rod 10 are respectively connected to the sprockets 3 of the left and right guide mechanisms and drive them to move.

[0034] In one embodiment, a plurality of linkage teeth 11 extend from the side wall of the slide plate 5 , and the linkage teeth 11 are inserted into the links of the transmission chain 4 to be connected thereto.

[0035] Working principle: The power mechanism in the utility model is usually a reduction motor box 9. After the high-speed power of the motor is reduced by the reduction motor box, it is responsible for providing low-speed and high-torque power. The reduction motor box 9 transmits the power to the sprockets 3 on both sides through the synchronization rod 10. The synchronization rod ensures that the sprockets of the left and right guide mechanisms rotate synchronously to maintain balanced movement.

[0036] In this case, each sprocket 3 drives the transmission chain 4 mounted thereon by rotating. Driven by the sprocket, the transmission chain performs a circular motion along the chain track plate 2 fixed to the inner side of the cabinet. The chain track plate is designed to be a hollow rectangular shape, and a guide rail groove 6 is opened on one side.

[0037] The transmission chain 4 is connected with a slide plate 5, which extends from the chain track plate and is connected to the lifting layer plate 1. The linkage teeth 11 arranged on the side wall of the slide plate 5 mesh with the chain links of the transmission chain to ensure that the slide plate moves up and down with the transmission chain. The guide block 7 protruding from the side wall of the slide plate extends into the guide groove of the chain track plate to slide, thereby improving the guiding accuracy during the lifting process and preventing swinging.

[0038] When the power mechanism is started, the synchronous rod and the sprocket are driven to work, and the interaction between the sprocket and the transmission chain drives the slide plate and the lifting plate 1 connected thereto to move up and down. This movement mechanism allows the plate to be lifted and lowered smoothly without relying on the deadweight of the cabinet.

[0039] Compared with traditional technology: the use of synchronization rods ensures perfect synchronization of the sprockets on both sides, effectively avoiding the common asynchrony and tilt problems in traditional wire winch systems. This synchronization significantly improves the stability and safety of operation.

[0040] At the same time, the mechanism using sprockets and transmission chains is more durable and less prone to damage than traditional wire ropes. This design reduces maintenance frequency and costs, and improves the overall life and reliability of the equipment.

[0041] In addition, through the precise design of the slide plate and guide block, the lifting plate can slide smoothly in the guide groove, greatly improving the smoothness of the lifting process. This not only optimizes the user experience, but also increases the operating accuracy of the mechanism. The design of this mechanism allows the lifting plate to operate smoothly with almost no reliance on the weight of the cabinet, which allows the lifting consistency and smoothness to be maintained even under light or uneven loads.

[0042] Combining the above working principles and technical advantages, the utility model provides a practical and efficient solution, improves the performance of the electric cabinet lifting mechanism, and makes it more in line with the needs of modern home and commercial environments.

[0043] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the claims created by the utility model.
