A supermarket shelf structure with automatic lifting and unfolding and its usage method

Abstract

This invention relates to the technical field of supermarket shelving, specifically a supermarket shelving structure with automatic lifting and retraction and its usage method. It includes two sets of side supports and a canopy on top of the two sets of side supports. Each set of side supports has a horizontal support plate at its bottom and a back plate between the two sets of side supports. This invention uses a single motor to synchronously drive the three shelves to lift as a whole. During the lifting process, the built-in extension plates of each shelf automatically extend outwards, automatically expanding the display area as the shelf height increases. High-level display and expansion of the display surface can be completed simultaneously without additional operation. Simultaneously, a locking mechanism can be used to pre-lock the three sets of extension plates before the shelf is lifted, keeping the extension plates in a retracted state when the shelf is lifted. This achieves independent control of the lifting and extension functions, improving the shelf's display flexibility and ease of operation.

Description

Technical Field

[0001] This invention relates to the technical field of supermarket shelving, specifically a supermarket shelving structure with automatic lifting and unfolding and its usage method. Background Technology

[0002] In retail venues such as shopping malls and supermarkets, supermarket shelves are a type of support device used to display, showcase, and store goods for sale. They are typically composed of uprights, shelves, back panels, and various hanging accessories. Their purpose is to present goods to customers in a neat and organized manner, with different categories and multiple layers on the facade, maximizing the display area and visual accessibility of goods within a limited store space. At the same time, they support the circulation operations of goods such as temporary storage, restocking, and customer self-selection. They are the core infrastructure for retail terminals to realize the display and sales delivery of goods.

[0003] Currently, the fixed or simple lifting shelves widely used in the supermarket retail sector mostly adopt standardized shelf structure design and realize basic merchandise display functions through modular assembly. Some shelves with lifting and adjustment capabilities have also been gradually applied to retail scenarios with different shelf height requirements, providing a stable basic support for the daily merchandise placement and space utilization of supermarkets.

[0004] However, in actual operation, there is still room for further optimization in the functional linkage and scenario adaptability of the above-mentioned shelves; the shelf display area of ​​most lifting shelves is relatively fixed, and it is impossible to dynamically expand the display space while adjusting the lifting; at the same time, the lifting and expansion functions of the shelves usually lack independent control mechanisms, and it is impossible to flexibly switch the usage mode according to actual operational needs. When carrying out regular replenishment, displaying small items or adjusting the layout of temporary sites, the operational flexibility needs to be improved, which to some extent limits the utilization efficiency and scenario adaptability of supermarket shelves. Summary of the Invention

[0005] The purpose of this invention is to provide a supermarket shelf structure with automatic lifting and unfolding and its usage method, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A supermarket shelf structure with automatic lifting and retraction includes two sets of side supports and a canopy on top of the two sets of side supports. Each set of side supports has a horizontal support plate at its bottom and a back plate between the two sets of side supports. Three chambers are formed on the back plate. A drive motor and a transmission assembly are mounted on the output shaft of the drive motor at the bottom of the back plate. Three sliding platforms and a shelf at one end of each sliding platform are equidistantly connected to the transmission assembly. The shelf is hollow and has slots. A sliding assembly and a hinge assembly are slidably mounted inside the shelf. A telescopic extension plate is slidably mounted inside the shelf. A common locking mechanism for locking the telescopic extension plate is provided between the two sets of horizontal support plates.

[0008] The above describes a structure for an automatically retractable supermarket shelf with lifting mechanism: the transmission assembly includes a transmission shaft mounted on the output shaft of the drive motor and three sets of threaded sections equidistantly spaced on the transmission shaft; the three sets of sliding platforms are respectively threaded onto the three sets of threaded sections; and the three sets of sliding platforms are respectively slidably mounted on the three sets of chambers on the back plate.

[0009] The above describes a type of supermarket shelf structure with automatic lifting and retraction: three sets of shelves are respectively set at one end of three sets of sliding platforms, and multiple brackets are set on each set of shelves. The end of the telescopic extension plate is provided with a tail support.

[0010] As described above, a supermarket shelf structure with automatic lifting and retraction: the sliding component includes a trapezoidal slider slidably installed inside the shelf and a sealing plate disposed at one end of the trapezoidal slider for covering the slot; the front end of the telescopic extension plate is provided with a sliding rod.

[0011] As described above, a supermarket shelf structure with automatic lifting and retraction: a spring is sleeved on the slide rod, the spring is connected to the front end of the telescopic extension plate, and the trapezoidal slider is slidably mounted on the slide rod.

[0012] The above describes a structure for an automatically retractable supermarket shelf with lifting mechanism: the hinge assembly includes three support blocks respectively disposed above the three sets of chambers, the three sets of support blocks are respectively disposed above the three sets of threaded sections, and three sets of deflection plates are respectively hinged between the three sets of support blocks and the three sets of trapezoidal sliders.

[0013] The above describes a structure for an automatically retractable supermarket shelf with lifting mechanism: the plug-in locking mechanism includes a screw rotatably disposed between two transverse support plates and a sliding frame threaded onto the screw, with a knob sleeved on one end of the screw.

[0014] As described above, a supermarket shelf structure with automatic lifting and retraction: a guide rod is provided between the two horizontal support plates, the sliding frame is slidably mounted on the guide rod, and three sets of sliding grooves are provided on the sliding frame.

[0015] The above describes a structure for an automatically retractable supermarket shelf: the plug-in locking mechanism includes three plug rods that are slidably installed on the three slide grooves respectively, and the sides of the three telescopic extension plates are provided with plug-in interfaces. The three plug rods are plugged into the three plug-in interfaces respectively.

[0016] The method of using the above-described lifting and automatic retraction supermarket shelf structure includes the following steps:

[0017] Step 1: This supermarket shelf is in the low-position storage state by default. All three shelves are in the initial low position, and the telescopic extension panels inside each shelf are in the retracted storage state. Start the drive motor, which drives the three sliding platforms to rise synchronously through the transmission shaft, so that the three load-bearing shelves rise synchronously and smoothly.

[0018] Step 2: During the rising process of the shelf, the deflection plate deflects in a suitable manner to drive the trapezoidal slider to slide. The trapezoidal slider extends the telescopic extension plate outward at a constant speed through the spring until the shelf reaches the target height, at which point the extension plate completes the extension action simultaneously.

[0019] Step 3: If the telescopic extension plate does not need to be unfolded, before the shelf lifting operation, turn the knob to drive the screw to rotate. The screw drives the sliding frame to slide, and the sliding frame drives the three sets of plug rods to be inserted into the plug interface on the side of the three telescopic extension plates for limiting.

[0020] Step 4: After the operation is completed, start the drive motor. At this time, the drive motor will only drive the three shelves to complete the synchronous lifting action. The telescopic extension plate will remain in a retracted state because it is locked and will not move with the shelves as they rise.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The three shelves are raised and lowered synchronously by a single motor. During the raising process, the built-in extension panels of each shelf automatically extend outward, which automatically expands the display area while the shelf height is increased. High-level display and display surface expansion can be completed simultaneously without additional operation. At the same time, the three sets of extension panels can be pre-locked before the shelf is raised by the plug-in locking mechanism, so that the extension panels remain in a retracted state when the shelf is raised. This realizes independent control of the lifting and extension functions, which improves the display flexibility and operation convenience of the shelf.

[0023] This invention achieves controllable separation of shelf lifting and extension functions, adapting to various usage scenarios such as conventional placement and widened display, and also meets the actual usage needs of supermarkets for daily replenishment, display adjustment and site layout changes.

[0055] The method of using the above-described lifting and automatic retraction supermarket shelf structure includes the following steps:

[0056] Step 1: The supermarket shelf is in a low-position storage state by default. All three item placement shelves 10 are in the initial low position, and the telescopic extension plates 13 inside each shelf 10 are in a retracted storage state. Start the drive motor 6, which drives the three sliding platforms 9 to rise synchronously through the transmission shaft 7, so that the three load-bearing shelves 10 rise synchronously and smoothly.

[0057] Step 2: During the rising process of shelf 10, deflection plate 20 performs applicable deflection and synchronously drives trapezoidal slider 18 to slide. Trapezoidal slider 18 extends telescopic extension plate 13 outward at a constant speed through spring 17 until shelf 10 rises to the target height, at which point extension plate synchronously completes the extension action.

The screw 22 drives the sliding frame 25 to slide, and the sliding frame 25 drives the three sets of plug rods 27 to be inserted into the plug interface 15 on the side of the three telescopic extension plates 13 for limiting.

[0059] Step 4: After the operation is completed, start the drive motor 6. At this time, the drive motor 6 will only drive the three shelves 10 to complete the synchronous lifting action. The telescopic extension plate 13 will remain in a retracted state because it is locked and will not be displaced as the shelves 10 rise.

[0060] The above embodiments are exemplary and not restrictive. Therefore, any technical solutions that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention are included within the scope of the present invention.
