Description

Technical Field

[0001] This application relates to the field of lifting devices, and more particularly to a lifting device for displaying items. Background Technology

[0002] In the field of exhibitions, especially in the display of valuable items such as jewelry, cultural relics, and precision instruments, traditional display devices (such as display stands, display cases, and rotating trays) generally suffer from the drawback of fixed and non-adjustable height. These devices typically employ static support structures, making it impossible to flexibly adjust the display height and viewing angle according to display needs, thus limiting the viewing experience. A more significant problem is that after the exhibition, valuable items need to be frequently removed from the fixed-height device and stored in a safe space. This repeated handling can easily lead to the following risks: physical collisions: items coming into contact with the device's frame during manual handling can easily cause scratches or structural damage; accidental drops: small valuable items (such as jewelry and chips) are at risk of slipping during transfer; lack of stability: existing devices lack lifting and cushioning mechanisms, making items susceptible to inertial impacts during movement. Although some display racks are designed with detachable structures, the disassembly and assembly process still cannot avoid human contact and is inefficient. Therefore, there is an urgent need for a display device with a safe lifting function that can achieve flexible height adjustment and integrated storage without the need to transfer items, fundamentally reducing the risks associated with the safekeeping of valuable items. Utility Model Content

[0003] The technical problem this application aims to solve is that existing display devices have a fixed and non-adjustable height, making them unsuitable for displaying items of different heights. Furthermore, storing items after viewing requires manual transfer, which poses a certain risk. To address these shortcomings of the existing technology, this application provides a lifting device for displaying items.

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is: A lifting device for displaying items is constructed, including a base with at least one set of mounting slots. A lifting unit is connected to the mounting slots. The lifting unit includes a drive module and a lifting module that moves up and down under the action of the drive module. The drive module includes a motor, a control board connected to the motor, and a terminal block connected to the control board. The lifting module includes a lifting column and a display box that moves synchronously with the lifting column. The item to be displayed is placed in the display box. When the motor is working, the motor shaft drives the lifting column to move up and down, which in turn drives the display box to move up and down.

[0005] Preferably, the drive module further includes a housing placed outside the motor, with a lower fixing plate below the housing and an upper fixing plate above the housing. The upper fixing plate has a square hole in the middle, through which the lifting column passes and moves up and down.

[0006] Preferably, the drive module further includes a movable plate connected to the motor, the movable plate being connected to the lifting column, and both the movable plate and the lifting column having a shaft hole corresponding to the motor shaft. When the motor is working, the motor shaft rotates to drive the movable plate and / or the lifting plate to move up and down.

[0007] Preferably, a lower chamber for the lifting column is provided above the movable plate, the lower end of the lifting column is placed in the lower chamber, and a lifting column limiting groove is provided on the peripheral wall of the lower chamber, which is connected to the lifting column.

[0008] Preferably, the drive module further includes a linear guide rail. The lower fixed plate and the upper fixed plate are provided with guide rail holes corresponding to the linear guide rail. The two ends of the linear guide rail are placed in the guide rail holes of the upper fixed plate and the lower fixed plate. The moving plate and the lifting column are provided with guide rail holes corresponding to the linear guide rail. The linear guide rail passes through the guide rail holes of the moving plate and the lifting column, and the guide rail holes of the moving plate and the lifting column can move on the linear guide rail.

[0009] Preferably, a limiting plate is provided at the lower end of the upper fixing plate and at the upper end of the upper fixing plate. The outer wall of the limiting plate contacts the inner wall of the outer shell to connect the upper fixing plate and the lower fixing plate to the outer shell.

[0010] Preferably, the lifting device includes a protective cover placed outside the lifting column, the protective cover moving synchronously with the lifting column, and the display box includes a display box bottom shell and a display box top cover placed on the display box bottom shell, forming a storage cavity between the display box bottom shell and the display box top cover, and the item to be displayed is placed in the storage cavity.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this application. Obviously, the described embodiments are some embodiments of this application, but not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0017] This application discloses a lifting device for displaying items according to a preferred embodiment; this lifting device can be used for displaying valuable items such as jewelry, ornaments, and watches, as well as collectible items such as figurines. Figures 1-2 As shown, the lifting device includes a base 1, with multiple sets of mounting slots 10 formed in the middle of the base. Each set of mounting slots can accommodate a lifting unit 2. In this application, a total of four sets of mounting slots 10 are provided, corresponding to four sets of lifting units 2. The base can be installed into the cavity to be installed through the outer flange 11 to facilitate the display of valuables or collectibles. It should be noted that the number and arrangement of the mounting slots 10 on each set of base 1 can be set as needed. For example, the mounting slots can be arranged in a matrix, or they can be arranged to display a predetermined pattern, such as a pattern formed in the air by a drone. The arrangement and number of mounting slots are not specifically described here. There is no creative change to the mounting slots themselves; only changes to the number and arrangement of the patterns formed should fall within the protection scope of this application.

[0018] Specifically, such as Figures 2-4 As shown, the lifting unit 2 includes a drive module 21 and a lifting module 20 connected to the drive module. The drive module drives the lifting module to rise and fall, facilitating the display of items and their subsequent storage, without requiring contact with the items to be displayed. When an item needs to be displayed, the drive module drives the lifting module to rise, raising the display box 200 from the bottom. After display, the drive module drives the lifting module to fall, and the display box falls synchronously with the lifting module. Once it falls to a specified depth, the displayed item is hidden. Therefore, the lifting device of this application should be installed in the mounting cavity. When the display box falls to the upper surface of the mounting cavity, the mounting cavity can hide the display box, or the lifting device can be hidden by a cover plate (not shown in the figure) on the upper part of the mounting cavity. When display is needed, the cover plate is opened, and the drive device 21 drives the lifting device 20 to rise, exposing the display box 200 on the upper surface of the mounting cavity and reaching the specified height.

[0019] Furthermore, such as Figures 2-4As shown, the drive module 21 includes a motor 213, with a lower fixed plate 212 connected to the lower end of the motor 213. A housing 210 is provided outside the motor, with its lower end connected to the lower fixed plate and its upper end connected to an upper fixed plate 211. A control board is also provided inside the housing, connected to the motor and driving its operation. The control board also includes a display screen 214 and buttons 215 connected to the control board. The display screen can show information about the items to be displayed, as well as other information that needs to be displayed. The buttons allow the lifting module to be raised and lowered using a handle. A motor shaft 2130 is located above the motor 213, with a moving plate 216 connected to the motor shaft. When the motor operates, the motor shaft rotates, causing the moving plate to move up and down. By placing the lifting device on the moving plate, the lifting device can move synchronously with the movement of the moving plate. Below the lower fixed plate 212, there is a connector 22 that connects to the control board. The connector supplies power to the drive module and can also transmit relevant control signals. This allows multiple lifting modules to be synchronized and linked, and the lifting height of different lifting modules can be controlled as needed to achieve a more three-dimensional display effect and a better display effect.

[0020] Furthermore, such as Figures 3-7As shown, the lower fixing plate 2112 is placed below the base 1, and the four corners of the lower fixing plate are provided with extended fixing ears 2120. The driving module is connected and fixed to the base by connecting to the lower part of the base through the fixing ears. The lower fixing plate 212 is provided with four sets of limiting plates 2112, which correspond to the four corners of the outer shell 210, thereby facilitating the connection between the outer shell and the lower fixing plate. At the same time, a motor chamber 2121 is formed in the middle of the lower fixing plate, and the motor 213 is fixed in the motor chamber. The lower end of the upper fixing plate 211 is also provided with limiting plates 2112 corresponding to the four corners of the outer shell, so as to facilitate the connection between the outer shell and the upper fixing plate. The middle of the moving plate is provided with a rotating shaft hole 2160, and the motor shaft rotates at the rotating shaft hole to drive the moving plate to rise and fall. To ensure the vertical rise and fall of the moving plate, the drive module 21 is equipped with two sets of linear guides 217. Guide holes 2111 are provided on the lower part of the upper fixed plate 211 and the upper end of the lower fixed plate 212 corresponding to the linear guides. The two ends of the linear guides are placed in the guide holes, thus fixing the linear guides through the upper and lower fixed plates. Guide holes 2111 are also provided on the left and right sides of the moving plate. The linear guides pass through these guide holes to connect the linear guides and the moving plate, and the guide holes are located on both sides of the moving plate. Correspondingly, the two sets of linear guides are also located on both sides of the moving plate to achieve synchronous rise and fall of both sides of the moving plate, thus realizing the vertical up and down movement of the moving plate. A lifting module chamber 2161 is provided above the moving plate, and the lifting module is placed below within the lifting module chamber. A square hole 2110 is provided in the middle of the upper fixed plate corresponding to the lifting module. The lifting module passes through the square hole, allowing it to move with the moving plate. The inner periphery of the lifting module cavity is also provided with a lifting module limiting groove 2162, which limits the lifting module, so that the lifting module is tightly connected to the moving plate and maintains synchronous movement.

[0021] Furthermore, such as Figures 5-6 and Figures 8-12As shown, the lifting module 20 includes a lifting column 202, a display box 200 positioned above the lifting column, and a protective cover 201 fitted over the lifting column. A light panel 203 is positioned between the lifting column and the display box. The display box should be transparent so that the items to be displayed can be observed when placed inside. Simultaneously, the light panel provides brightness for the display of the items, achieving a better display and viewing effect. The lower end of the lifting column 202 is placed within the lifting module cavity and connected to the lifting module's limiting groove 2162. The lifting column moves up and down synchronously with the moving plate, thereby causing the display box and protective cover to move up and down synchronously with the moving plate. Simultaneously, the lifting column passes through a square hole 2110. Guide rail holes 2111 are provided on both sides of the lifting column. The linear guide rails also serve as guide rail holes for the fruit lifting column, ensuring that the lifting column maintains vertical up-and-down movement. To avoid excessive weight of the lifting device causing high resistance when the moving plate rises, a pivot hole 2160 is also provided at the bottom of the lifting device. The motor shaft 2130 passes through the pivot hole, so that when the motor shaft rotates, it simultaneously drives the moving plate and the lifting column to move up and down. This avoids the situation where the moving plate malfunctions and cannot move up and down with the motor shaft, but the lifting column can still move up and down under the action of the motor shaft. If the lifting column cannot move up and down directly with the motor shaft, the moving plate can drive the lifting column to move up and down by rotating with the motor shaft, ensuring smooth up and down movement of the lifting column and avoiding the potential danger of the pivot hole of the moving plate or the lifting column not contacting the motor shaft and thus not being able to move up and down with the motor shaft.

[0022] Furthermore, such as Figures 8-12 The protective cover 201, placed outside the lifting column, conceals the drive unit to prevent visitors from touching the display screen or buttons. Inside the protective cover is an upper chamber 2011 for the lifting column, containing a buckle 2010. A corresponding latch 2014 is located on the side of the lifting column, connecting the lifting column and the protective cover and ensuring synchronized movement of the protective cover with the lifting column. The maximum stroke of the drive module should be such that the lower edge 2012 of the protective cover is flush with the upper surface of the mounting cavity. Above the protective cover 201 is a light panel chamber 2013, containing the light panel 203. The protective cover is connected to the display box via buckles and latches. Since the display box is transparent, the light panel illuminates the displayed items. The display box 200 includes a display box top cover 2000 and a display box bottom shell 2001 corresponding to the display box top cover. The display box top cover and the display box bottom shell together form a storage cavity 2002. The item to be displayed is placed in the storage cavity. At the same time, magnetic holes 2003 are provided around the display box top cover and the display box bottom shell. Magnets 2004 are installed in the magnetic holes, so as to facilitate the display box top cover to be closed on the display box bottom shell.

[0023] When the lifting device of this application is in operation, a control signal is sent to the control board via the connector 22 to activate the motor 213, thereby driving the motor shaft 2103 to rotate. The rotation of the motor shaft causes the moving plate 216 and / or the lifting column 202 to rise, and also causes the protective cover 201 and the display box 200 to rise until the display box reaches the specified height or the required height, at which point the motor stops working. Then, the light panel 203 emits light to provide display brightness to the display box, thus achieving a better display effect. At the same time, since the connector can realize the linkage of multiple lifting modules, different lifting modules can be raised at different heights according to the required effect, and different colors of light can be emitted by the light panel, thus achieving a better display effect through the lifting modules. Moreover, the multiple display modules can be linked together, resulting in a better and more dazzling display effect.

[0024] It should be understood that this application has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this application. Furthermore, based on the teachings of this application, these features and embodiments can be modified to suit specific circumstances and materials without departing from the spirit and scope of this application. Therefore, this application is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this application.
