Shelf power supply device and display stand

Abstract

The present invention discloses a layer board power supply device and a display stand. When the layer board and the display stand are assembled, the power supply housing drives the power supply electrode to move toward the power supply electrode under the top of the display stand until the power supply electrode contacts the power supply electrode. The position stabilizing component can adjust the position of the power supply electrode at any time under the pressure of the power supply housing to ensure that the power supply electrode and the power supply electrode remain in contact. Therefore, regardless of whether the assembly between the layer board and the display stand is tight, the position stabilizing component can ensure that the power supply electrode and the power supply electrode remain in contact, and the power supply electrode and the power supply electrode will not separate due to the loose assembly of the layer board and the display stand after being used for too long, thereby ensuring the stability of power supply.

Description

Technical Field

[0001] The invention relates to a layer board power taking device and a display rack. Background Art

[0002] Display racks are widely used in supermarkets, shopping malls and other places. In order to display goods, it is necessary to install lighting on the display racks. In the past, the power supply of the display racks was set on the backlight side of the display racks, so the LED lamps on the display racks were connected to the power supply by passing wires through or winding the wires from the display racks to the back of the display racks. This method has been criticized for problems such as too many wires, messy wiring, and poor maintenance and aesthetics.

[0003] Alternatively, for example, the Chinese utility model patent application number is 2020200701920.7, and the patent name is a patent for a shelf layer board power supply structure, which includes a power supply plug fixed on the layer board and a conductive slot fixed on the shelf, wherein the power supply plug includes a main shell, and the main shell is provided with card slots on both sides to be fixed on the mounting holes at the rear end of the layer board, and the rear end of the main shell is extended backward to be provided with electrode needles, and the electrode needles are electrically connected to the electrical appliances; the conductive slot includes a main slot body and a mounting slot provided on the front, and an electrode sheet is installed in the mounting slot to be electrically connected to the power supply. After the power supply plug is docked with the conductive slot, the electrode needle is inserted into the mounting slot to contact and conduct with the electrode sheet. When the layer board and the shelf are assembled, the power supply plug can be directly electrically connected to the conductive slot to realize circuit connection. However, when this type of device is used to draw power from the layer board, the power supply plug needs to be accurately aligned with the conductive slot before the layer board and the shelf can be assembled and powered, and assembly and power supply are relatively troublesome. Moreover, after the assembly of the shelves and the shelves is completed, since there is no pre-pressure between the power plug and the conductive slot, when used for a long time, the shelves will tilt, bend, etc., resulting in a loose assembly between the shelves and the display rack, which will cause separation between the power plug and the conductive slot, resulting in poor contact or disconnection between the electrode needle and the electrode sheet. Summary of the invention

[0004] The present invention provides a layer board power extraction device and a display stand, which overcomes the disadvantages of poor contact or disconnection between the electrode needle and the electrode sheet in the background art. One of the technical solutions adopted by the present invention to solve the technical problem is:

[0005] A layer plate power supply device, which is suitable for a display rack, and a power connection electrode is provided on the display rack, and is characterized in that: the layer plate power supply device comprises a layer plate and a power supply module, the power supply module comprises a power supply housing, a power supply electrode, a position stabilizing component and a blocking component, the power supply housing can move relative to the layer plate under the top of the display rack, the power supply electrode is installed in the power supply housing and can move with the power supply housing, the blocking component is relatively fixed to the layer plate, and the position stabilizing component is sandwiched between the power supply housing and the blocking component;

[0006] When the layer plate is assembled with the display rack, the power taking shell drives the power taking electrode to move toward the power receiving electrode under the top support of the display rack until the power taking electrode contacts the power receiving electrode. The position stabilizing component can adjust the position of the power taking electrode at any time under the squeezing of the power taking shell to ensure that the power taking electrode remains in contact with the power receiving electrode.

[0007] In a preferred embodiment, the position stabilizing component includes an elastic member having an elastic energy storage function.

[0008] In a preferred embodiment, the position stabilizing component is a spring or a torsion spring.

[0009] In a preferred embodiment: the display rack includes a column and a hanging plate, the hanging plate is detachably connected to the column, the hanging plate is provided with an extrusion channel, the power-connecting electrode faces the extrusion channel, the power-taking shell is slidably matched with the extrusion channel, and when the power-taking shell is slidably matched with the extrusion channel, the power-taking shell moves relative to the layer plate to extrude the position stabilizing component.

[0010] In a preferred embodiment, the extrusion channel is vertically connected and is in a trapezoidal shape with a larger upper portion and a smaller lower portion, and the shape of the power extraction housing is adapted to the shape of the extrusion channel.

[0011] In a preferred embodiment: a base is fixedly provided on the side of the layer plate, the base is detachably connected to the hanging plate, the blocking component is fixed to the base, and the power collection housing is slidably mounted on the base; the power connection electrode is vertically arranged on the column.

[0012] In a preferred embodiment: the base is provided with a through slide groove and a slider, and the slider is slidably matched with the through slide groove and fixedly connected with the power extraction housing.

[0013] In a preferred embodiment: the hanging plate is provided with a snap-fitting portion, and the base is provided with a snap-fitting fitting portion, and the detachable connection between the base and the hanging plate is achieved through snap-fitting between the snap-fitting portion and the snap-fitting fitting portion.

[0014] In a preferred embodiment: the power extraction module further includes a power extraction circuit, a display light is provided on the layer plate, and the power extraction circuit is electrically connected to the display light and the power extraction electrode.

[0015] The second technical solution adopted by the present invention to solve the technical problem is: a display rack, which uses the layer board power supply device.

[0016] Compared with the background technology, this technical solution has the following advantages:

[0017] 1. When the shelf and the display rack are assembled, the power-collecting housing drives the power-collecting electrode to move toward the power-connecting electrode under the top of the display rack until the power-collecting electrode contacts the power-connecting electrode. The position-stabilizing component can adjust the position of the power-collecting electrode at any time under the pressure of the power-collecting housing to ensure that the power-collecting electrode and the power-connecting electrode remain in contact. Therefore, regardless of whether the assembly between the shelf and the display rack is tight or not, the position-stabilizing component can ensure that the power-collecting electrode and the power-connecting electrode remain in contact, and the power-collecting electrode and the power-connecting electrode will not separate due to the loose assembly of the shelf and the display rack after being used for too long, thereby ensuring the stability of power collection.

[0018] 2. The position stabilizing component includes an elastic member with an elastic energy storage function, that is, the elastic member can use its own elastic force to fine-tune the position of the power-taking electrode to ensure the stability of power taking.

[0019] 3. When the power taking housing and the extrusion channel are slidably matched, the power taking housing moves relative to the layer plate to extrude the position stabilizing component, which is ingeniously designed, simple in structure and easy to implement.

[0020] 4. The extrusion channel runs through from top to bottom and is in the shape of a trapezoid with a larger top and a smaller bottom. The shape of the power taking shell is adapted to the shape of the extrusion channel, so that the power taking shell only needs to be roughly aligned with the extrusion channel for sliding fit, and the assembly of the power taking shell and the extrusion channel is more convenient. At the same time, the inclined edge of the trapezoid can guide the power taking shell, so that the power taking shell can be quickly inserted into the extrusion channel.

[0042] In this embodiment, the display rack includes four columns 20, and the left and right sides of each column 20 are provided with a plurality of hanging grooves 21 arranged at intervals up and down. The hanging plate 30 is located between the two side columns 20, and hooks 32 are provided at both ends of the hanging plate 30. The hooks 32 are connected to the hanging grooves 21 to achieve a detachable connection between the hanging plate 30 and the column 20.

[0043] Furthermore, the power electrodes 10 are provided with two and extend longitudinally, and are arranged on the left front column 20.

[0045] The layer plate power supply device includes a layer plate 40 and a power supply module 50, wherein the power supply module 50 includes a power supply shell 51, a power supply electrode 52, a position stabilizing component 53 and a blocking component 54, wherein the power supply shell 51 can move relative to the layer plate under the top pressure of the display rack, the power supply electrode 52 is installed in the power supply shell 51 and can move with the power supply shell 51, the blocking component 54 is relatively fixed to the layer plate 40, and the position stabilizing component 53 is sandwiched between the power supply shell 51 and the blocking component 54; when the layer plate 40 is assembled with the display rack, the power supply shell 51 drives the power supply electrode 52 to move toward the power supply electrode 10 under the top pressure of the display rack until the power supply electrode 52 contacts the power supply electrode 10, and the position stabilizing component 53 can adjust the position of the power supply electrode 52 at any time under the squeezing of the power supply shell 51 to ensure that the power supply electrode 52 remains in contact with the power supply electrode 10. Therefore, regardless of whether the assembly between the layer plate 40 and the display frame is tight or not, the position stabilizing component 53 can ensure that the power taking electrode 52 and the power receiving electrode 10 remain in contact with each other, and the power taking electrode 52 and the power receiving electrode 10 will not separate due to the loose assembly between the layer plate 40 and the display frame after being used for too long, thereby ensuring the stability of power collection.

Fig. 9 As shown, the position stabilizing component 53 is a spring. As required, the position stabilizing component 53 can also be replaced by a torsion spring.

[0047] The power taking housing 51 is slidably matched with the extrusion channel 31, and when the power taking housing 51 is slidably matched with the extrusion channel 31, the power taking housing 51 moves relative to the layer plate 40 to squeeze the position stabilizing component 53.

The extrusion channel 31 is through from top to bottom and is in the shape of a trapezoid with a larger top and a smaller bottom. The shape of the power supply housing 51 is adapted to the shape of the extrusion channel 31, so that the power supply housing 51 only needs to be roughly aligned with the extrusion channel 31 to slide and fit, and the assembly of the power supply housing 51 and the extrusion channel 31 is more convenient. At the same time, the inclined edge of the trapezoid can guide the power supply housing 51, so that the power supply housing 51 can be quickly inserted into the extrusion channel 31.

In addition, the blocking member 54 is in the form of a sheet and is located at the rightmost end of the base 41.

[0052] After assembly, the position stabilizing member 53 has two states, one of which is as follows: Fig.12 As shown, the position stabilizing member 53 is in a compressed state, and the other is as shown Fig.14 As shown, the position stabilizing component 53 is in a retracted state.

At the same time, the position stabilizing component 53 is compressed, and the power extraction electrode 52 moves to the right until the power extraction electrode 52 contacts the power connection electrode 10. The position stabilizing component 53 can fine-tune the position of the power extraction electrode 52 at any time to ensure that the power extraction electrode 52 and the power connection electrode 10 maintain good contact.
