Description

Technical Field

[0001] The present application relates to the technical field of furniture display equipment, and in particular to a furniture display rotating structure. Background Art

[0002] In order to better promote and sell the furniture products produced by the company, a small area is usually separated in exhibitions, shopping malls, hotels and other large venues, and display stands and display racks are installed in the area to place the furniture to be displayed, such as chairs, lighting and other household items. Display stands and display racks are generally equipped with a rotating structure to keep the furniture products placed on them rotating to achieve a better display effect.

[0003] In the related art, the driving component of the display stand with a rotating structure is generally installed inside the display stand, and a supporting plate connected to the driving component is installed on the upper surface of the display stand. The furniture products are placed on the supporting plate, and the supporting plate is driven to rotate by the driving component. The furniture products rotate with the supporting plate for better display.

[0004] The problem with the related technology is that some furniture products are large in size, so the corresponding display stands and supporting plates are also large in size, which causes the supporting plate to shake easily when the driving component drives the supporting plate to rotate, resulting in poor stability. To solve this problem, in the related technology, a guide rail is laid on the upper surface of the display stand, and a slider is provided on the supporting plate. The slider is slidably connected to the guide rail. As the supporting plate rotates, the slider slides along the guide rail to play a role of auxiliary support and guidance, thereby improving stability. However, during the display process, dust and impurities are easily accumulated in the guide rail, abnormal noise may occur during the sliding of the slider, and it is also inconvenient for the staff to clean.

[0020] By adopting the above technical solution, the first slot body and the second slot body are both used to limit the moving direction of the tooth plate.

[0021] Optionally, the sliding part includes a first sliding part and a second sliding part, and the first sliding part and the second sliding part are respectively slidably matched with the first slot body and the second slot body, and a reversing assembly is arranged in the driving cavity to enable the first sliding part to keep sliding in the first slot body and the second sliding part to keep sliding in the second slot body.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-5 This application is described in further detail.

[0035] The present application embodiment discloses a furniture display rotating structure. Figure 1 A furniture display rotating structure includes a display stand 1, one end surface of which is fixed on the ground, and the other end surface is used to place furniture products. A bearing part is installed on one end surface of the display stand 1 for placing furniture products. The bearing part is a plate-like structure for providing support for the furniture products. It can be understood by those skilled in the art that in order to ensure the stability of the furniture products, a fixing structure such as a pull rope, a fastener and a positioning member can also be provided on the bearing part to fix the position of the furniture products. The fixing structure adopts the existing technology and is not limited here.

[0036] Reference Figure 1 and Figure 2 A driving cavity 3 is provided inside the display stand 1, and a driving assembly 4 is installed in the driving cavity 3. The driving assembly 4 is used to drive the bearing part to rotate, and the furniture products fixed on the bearing part rotate accordingly, so as to achieve a better display effect.

[0037] Furthermore, the driving assembly 4 includes a gear 41 and a toothed plate 42 meshed with the outer side of the gear 41, and a driver 45 driving the gear 41 to rotate. The gear 41 and the toothed plate 42 are located on the same horizontal plane, the gear 41 is rotationally connected to the display stand 1, and the central axis of the gear 41 coincides with the central axis of the display stand 1, the driver 45 is installed below the gear 41, the output end of the driver 45 is connected to a rotating shaft 46, the gear 41 is key-connected to the rotating shaft 46, forming a structure in which the driver 45 drives the rotating shaft 46 to rotate, and the rotating shaft 46 drives the gear 41 to rotate synchronously. It can be understood that the driver 45 is composed of components such as a forward and reverse motor and a reducer.

[0038] Reference Figure 1The tooth plate 42 is specifically a long strip structure as shown in the figure, both ends of which are semicircular, and the outer peripheral surface of the tooth plate 42 is formed with teeth that cooperate with the gear ring. During the rotation of the gear 41, the tooth plate 42 can always maintain meshing with the gear 41 and move with the gear 41.

[0039] A displacement slide groove 12 is provided on the inner bottom wall of the display stand 1 constituting the driving chamber 3. The displacement slide groove 12 is used to limit the movable direction of the tooth plate 42. Specifically, the limiting slide groove is composed of a first groove body 121 and a second groove body 122. Figure 3 As shown, the first slot body 121 is annularly arranged around the outer periphery of the gear 41, and the second slot body 122 is triangularly arranged around the outer periphery of the first slot body 121. Each side of the first slot body 121 is tangent to the first slot body 121, and the two are connected at the tangent point.

[0040] A sliding portion is provided on the side of the tooth plate 42 facing the displacement slide groove 12, and the sliding portion includes a first sliding portion 43 slidably provided in the first groove body 121, and a second sliding portion 44 slidably provided in the second groove body 122. When the gear 41 rotates, the tooth plate 42 is driven to move, and the first sliding portion 43 and the second sliding portion 44 respectively move along corresponding trajectories, thereby limiting the movement direction of the tooth plate 42.

[0041] The above-mentioned bearing part specifically includes a first bearing part 2 and a second bearing part 13, wherein the first bearing part 2 corresponds to the tooth plate 42, and the second bearing part 13 corresponds to the gear 41. Specifically, a guide rail 5 recessed inwardly is formed on the side of the display stand 1 where the bearing part is provided, and a guide member 6 is provided on the side of the first bearing part 2 facing the display stand 1, and the guide member 6 is slidably fitted in the guide rail 5 and connected to the tooth plate 42. It can be understood that in order to make the first bearing part 2 and the tooth plate 42 have the same moving trajectory, the guide rail 5 should be configured to cooperate with the displacement slide 12, and the guide member 6 should be configured to cooperate with the sliding part, so as to form a structure in which when the gear 41 drives the tooth plate 42 to move, the tooth plate 42 can drive the first bearing part 2 to move synchronously through the guide member 6.

[0042] It should be noted that, in the process of the gear 41 driving the tooth plate 42 to move, in order to ensure the moving direction of the tooth plate 42, the first sliding part 43 keeps moving in the first slot body 121, and the second sliding part 44 keeps moving in the second slot body 122, a reversing assembly 14 is provided at the connection between the first slot body 121 and the second slot body 122. There are three groups of reversing assemblies 14, which are evenly distributed at the connection between the first slot body 121 and the second slot body 122.

[0043] Specifically, refer to Figure 3 and Figure 4The reversing assembly 14 includes a transmission rod 141 rotatably mounted on the outside of the second slot body 122, and an extrusion portion 142 and a push portion 143 are respectively provided at both ends of the transmission rod 141. One end of the transmission rod 141 provided with the extrusion portion 142 extends into the second slot body 122, and the other end provided with the push portion 143 is located at the connecting portion between the first slot body 121 and the second slot body 122.

[0044] Initially, the pressing part 142 extends into the second slot body 122 and blocks the second slot body 122, and the pushing part 143 is away from the connection between the first slot body 121 and the second slot body 122. As the tooth plate 42 moves to the connection between the first slot body 121 and the second slot body 122, the second sliding part 44 can keep moving the second slot body 122 extending in a straight line and abut against the pressing part 142 in front of its moving direction. As the second sliding part 44 continues to move, the pressing part 142 is pushed to rotate in a direction away from the first slot body 121, and the pushing part 143 rotates toward the connection between the first slot body 121 and the second slot body 122, and finally the pushing part 143 blocks the connection between the first slot body 121 and the second slot body 122, so that when the first sliding part 43 rotates to the connection between the first slot body 121 and the second slot body 122, it will not enter the second slot body 122 from the connection, but keep moving in the first slot body 121. Thus, the movable direction of the tooth plate 42 is guaranteed.

[0045] It can be understood that in order to ensure that the reversing assembly 14 can return to its original position after the tooth plate 42 passes through the reversing assembly 14, a torsion spring (not shown in the drawings) can be installed at the rotating connection of the transmission rod 141. When the second sliding portion 44 pushes the extrusion portion 142 away from the first slot body 121, the torsion spring is compressed. When the second sliding portion 44 passes, the torsion spring restores its deformation, so that the extrusion portion 142 blocks the second slot body 122 again, so that the reversing assembly 14 returns to its initial state.

[0046] Preferably, the first load-bearing part 2 is set as a long strip structure for placing some furniture products with a long length, and the number of the first load-bearing parts 2 arranged on the display stand 1 can be three, and the three first load-bearing parts 2 are evenly spaced, and the number of the tooth plates 42, the guide members 6 and the sliding parts should correspond to the number of the first load-bearing parts 2. In this way, multiple different furniture products can be displayed at the same time.

[0047] The second bearing part 13 is arranged in the middle of the display stand 1, and is preferably a circular plate-shaped structure, for placing some furniture products of moderate size with a small difference in length and width. The rotating shaft 46 connected to the driver 45 is used to provide support for the second bearing part 13. Specifically, an axial hole is opened in the middle of the display stand 1, and the end of the rotating shaft 46 away from the driver 45 passes through the axial hole and extends to the top of the display stand 1, and is connected to the second bearing part 13. When the rotating shaft 46 rotates, the second bearing part 13 can rotate accordingly. Preferably, a ball bearing matched with the rotating shaft 46 is installed in the axial hole to provide rotation support for the rotating shaft 46, which can reduce the shaking of the rotating shaft 46 and reduce noise.

[0048] Reference Figure 2 and Figure 5 An enclosure 7 is provided on both sides of the driving cavity 3 corresponding to the guide rail 5. The enclosure 7 is set to a structure with an L-shaped cross-section, and its side opening is connected to the side wall of the guide rail 5, and the upper opening is connected to the inner top wall of the display stand 1 to form a closed air supply channel 8. An air outlet 9 is opened on the side wall of the guide rail 5 facing the enclosure 7. The air outlet 9 is long and arranged along the extension direction of the guide rail 5. An air supply device is installed in the driving cavity 3. The air supply device is preferably a fan. The air outlet end of the fan is connected to the enclosure 7 and communicated with the air supply channel 8, so as to output compressed air into the air supply channel 8.

[0049] Furthermore, an air inlet 11 is provided on the outer peripheral surface of the display stand 1 near one end of the bearing part, and the air inlet 11 connects the drive chamber 3 with the outside. Preferably, the end of the air inlet near the outside gradually extends upward, forming a structure in which air enters from the upper port and is sent out from the lower port to the drive chamber 3. When the air supply device is working, the outside air enters the drive chamber 3 from the air inlet 11, and then enters the air supply channel 8 through the air supply device, and then is discharged to the guide rail 5 through the air outlet 9. A large part of the compressed air entering the guide rail 5 flows upward to the outside, which can prevent dust from accumulating in the guide rail 5. At the same time, in the process of the outside air entering the air supply channel 8 from the drive chamber 3, part of the heat in the drive chamber 3 can be taken away, which plays a certain heat dissipation role.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
