Description

Technical Field

[0001] This application relates to the field of furniture technology, and in particular to a lifting mechanism and a dining table. Background Technology

[0002] Currently, various multifunctional dining tables have appeared on the market, such as those that combine mahjong and dining functions, or those that are equipped with an induction cooker to provide heating. Depending on the usage needs, the structure of the dining table needs to be changed manually or automatically. When changing, a lifting mechanism is usually set up inside. However, the lifting mechanisms currently used inside the dining table take up a lot of height space, have a complex structure, and are cumbersome to operate, resulting in a relatively high manufacturing cost for such dining tables. Utility Model Content

[0003] The main objective of this application is to provide a lifting mechanism and a dining table, which aims to solve the technical problem that existing lifting mechanisms used inside dining tables occupy a lot of height space.

[0004] To achieve the above objectives, this application provides a lifting mechanism and a dining table, including an outer frame, an inner frame, a pull cable, a transmission mechanism, and two lifting components. The outer frame is installed inside the dining table; the inner frame is movably disposed within the outer frame; the pull cable movably passes through the outer frame; the transmission mechanism is disposed within the outer frame and located below the inner frame, and is connected to one end of the pull cable extending into the outer frame; the two lifting components are respectively located near the inner sidewall of the outer frame and below the inner frame. Each lifting component includes a horizontal sliding plate, one side of which is hinged to the transmission mechanism. The transmission mechanism is used to drive the two horizontal sliding plates to slide horizontally simultaneously. The transverse sliding plate has a horizontal waist-shaped hole and an oblique waist-shaped hole. A first guide is slidably installed in the horizontal waist-shaped hole. One end of the first guide extends out of the horizontal waist-shaped hole and is connected to a fixed plate. The fixed plate is fixedly connected to the inner bottom of the outer frame. A second guide is movably installed in the oblique waist-shaped hole. One end of the second guide extends out of the oblique waist-shaped hole and is connected to a lifting plate. The lifting plate is fixedly connected to the bottom of the inner frame. A vertical waist-shaped hole is installed on the lifting plate. A third guide is slidably installed in the vertical waist-shaped hole. One end of the third guide extends out of the vertical waist-shaped hole and is connected to the fixed plate.

[0005] Optionally, the transmission mechanism includes a movable shaft, three first connecting pieces and two second connecting pieces. The two ends of the movable shaft are movably connected between the two inner sidewalls of the outer frame. The three first connecting pieces are all fixedly sleeved on the movable shaft, and the first connecting piece in the middle is connected to the pull wire. One end of the two second connecting pieces is respectively hinged to the first connecting pieces on both sides, and the other end of the two second connecting pieces is respectively hinged to one end of the corresponding transverse sliding plate.

[0006] Optionally, the first guide member includes a connector and a bearing sleeve, one end of which is connected to a fixed plate; the bearing sleeve is movably sleeved on the connector and slidably disposed within a horizontal oblong hole; the structures of the second and third guide members are the same as those of the first guide member.

[0007] Optionally, each lateral sliding board is equipped with a fixed plate and a lifting plate near its two sides.

[0008] Optionally, it also includes a fixing plate and a heating device, the fixing plate being embedded inside the inner frame; the heating device being disposed on the fixing plate.

[0009] Optionally, a bearing turntable located on a fixed plate is provided inside the inner frame, and the heating device is located inside the inner ring of the bearing turntable.

[0010] To achieve the above objectives, this application also provides a dining table, including the aforementioned lifting mechanism.

[0011] Optionally, the device includes a liner, an outer frame embedded in the liner, fan-shaped panels on both sides of the top surface of the liner, and a rotatable tabletop on the top surface of the liner, which can be rotated to form a circular tabletop with the two fan-shaped panels.

[0012] Optionally, a mounting bracket is provided at the bottom of the liner, and a handle is hinged inside the mounting bracket, with one end of the handle connected to a pull cord.

[0013] Optionally, the bottom of the liner is connected to multiple support feet.

[0014] The beneficial effects that this application can achieve are as follows:

[0015] Based on the lifting mechanism of this application, when a lifting operation is required, the pull cable is directly pulled to cause the transmission mechanism to drive the two transverse sliding plates. Since the fixed plate is fixed to the outer frame and does not move, the transverse sliding plate can only slide horizontally under the limiting guidance of the first guide member and the horizontal waist-shaped hole fixed to the fixed plate. At the same time, under the combined limiting guidance of the second guide member and the oblique waist-shaped hole, and the limiting guidance of the third guide member and the vertical waist-shaped hole, the lifting plate can only rise vertically, thereby lifting the inner frame separately. When storing, the pull cable is directly released, and the inner frame sinks and resets under the action of the weight of each part, thereby realizing the lifting function. The operation is convenient and quick, and the horizontal movement of the transverse sliding plate can be converted into the vertical movement of the lifting plate. The structure is compact, reducing the occupation of height space, and the manufacturing cost is also relatively low. Attached Figure Description

[0032] Example 1

[0033] Reference Figures 1-5This embodiment provides a lifting mechanism, including an outer frame 110, an inner frame 120, a pull cable 130, a transmission mechanism 140, and two lifting components 150. The outer frame 110 is installed inside a dining table; the inner frame 120 is movably disposed within the outer frame 110; the pull cable 130 movably passes through the outer frame 110; the transmission mechanism 140 is disposed within the outer frame 110 and located below the inner frame 120, and the transmission mechanism 140 is connected to one end of the pull cable 130 extending into the outer frame 110; the two lifting components 150 are respectively close to the inner sidewall of the outer frame 110 and located below the inner frame 120. Each lifting component 150 includes a transverse sliding plate 151, one side of which is hinged to the transmission mechanism 140. The transmission mechanism 140 is used to drive the two transverse sliding plates 151 to slide horizontally simultaneously. The frame has a horizontal waist-shaped hole 1511 and an oblique waist-shaped hole 1512. A first guide member 152 is slidably disposed in the horizontal waist-shaped hole 1511. One end of the first guide member 152 extends out of the horizontal waist-shaped hole 1511 and is connected to a fixing plate 153. The fixing plate 153 is fixedly connected to the inner bottom of the outer frame 110. A second guide member 154 is movably disposed in the oblique waist-shaped hole 1512. One end of the second guide member 154 extends out of the oblique waist-shaped hole 1512 and is connected to a lifting plate 155. The lifting plate 155 is fixedly connected to the bottom of the inner frame 120. A vertical waist-shaped hole 1551 is provided on the lifting plate 155. A third guide member 156 is slidably disposed in the vertical waist-shaped hole 1551. One end of the third guide member 156 extends out of the vertical waist-shaped hole 1551 and is connected to the fixing plate 153.

[0034] In this embodiment, when a lifting operation is required, the pull cable 130 is pulled directly to make the transmission mechanism 140 drive the two transverse sliding plates 151 to move. Since the fixed plate 153 is fixed to the outer frame 110 and does not move, the transverse sliding plate 151 can only slide horizontally under the limiting guidance of the first guide member 152 and the horizontal waist-shaped hole 1511 fixed on the fixed plate 153. At the same time, under the combined limiting guidance of the second guide member 154 and the oblique waist-shaped hole 1512 and the third guide member 156 and the vertical waist-shaped hole 1551, the lifting plate 155 can only rise vertically, thereby lifting the inner frame 120 separately. When storing, the pull cable 130 is released directly, and the inner frame 120 sinks and resets under the weight of each part, thereby realizing the lifting function. The operation is convenient and quick, and the horizontal movement of the transverse sliding plate 151 can be converted into the vertical movement of the lifting plate 155. The structure is compact, the height space occupied is reduced, and the manufacturing cost is relatively low.

[0035] It should be noted that the inner frame 120, outer frame 110, and other components in this embodiment can all be made of low-cost sheet metal, avoiding the drawbacks of long machining cycles and high costs. The pull wire 130 can be made of steel wire to ensure strength. This lifting mechanism is simple and practical to operate, occupies little height space, and has an overall reset thickness of about 40mm. It can be widely used in mahjong folding dining tables or dining tables with heating functions. A mahjong machine or induction cooker can be correspondingly configured inside the inner frame 120. For example, when a user wants to play mahjong at home, they can pull out the mahjong machine from under the dining table, and then push it back under the dining table after playing. The operation is convenient and quick.

[0036] As an optional implementation, the transmission mechanism 140 includes a movable shaft 141, three first connecting pieces 142 and two second connecting pieces 143. The two ends of the movable shaft 141 are movably connected between the two inner side walls of the outer frame 110. The three first connecting pieces 142 are all fixedly sleeved on the movable shaft 141, and the first connecting piece 142 in the middle is connected to the pull wire 130. One end of the two second connecting pieces 143 is respectively hinged to the first connecting pieces 142 on both sides, and the other end of the two second connecting pieces 143 is respectively hinged to one end of the corresponding transverse sliding plate 151.

[0037] In this embodiment, when the pull cable 130 is subjected to tension, it can pull the middle first connecting piece 142 to swing, thereby driving the movable shaft 141 to rotate, so as to drive the first connecting pieces 142 on both sides to swing synchronously, and then drive the second connecting piece 143 to swing, thereby pulling the transverse sliding plate 151 to slide, thus realizing the function of driving the two transverse sliding plates 151 to slide horizontally at the same time through a pull cable 130, and finally realizing the lifting operation. Moreover, the transmission mechanism 140 has a compact structure, occupies little space, and meets the usage requirements.

[0038] As an optional implementation, the first guide member 152 includes a connector and a bearing sleeve. One end of the connector is connected to the fixed plate 153. The bearing sleeve is movably sleeved on the connector and is slidably disposed in the horizontal waist-shaped hole 1511. The structures of the second guide member 154 and the third guide member 156 are the same as those of the first guide member 152.

[0039] In this embodiment, the first guide member 152 connects to the fixed plate 153 through the connector, and slides with the horizontal waist-shaped hole 1511 through the bearing sleeve, which can reduce wear during sliding and improve service life. Similarly, the second guide member 154 and the third guide member 156 also adopt this structure, which results in low wear and smooth sliding.

[0040] It should be noted that the above-mentioned connectors can be bolts, thereby forming a detachable connection with the fixing plate 153, which facilitates disassembly and assembly and reduces manufacturing difficulty.

[0041] As an optional implementation, each transverse slide 151 is provided with a fixed plate 153 and a lifting plate 155 near its two sides, so that when each transverse slide 151 slides horizontally, it can drive at least two lifting plates 155 to move vertically, thereby providing stable support for the four corners of the bottom of the inner frame 120.

[0042] As an optional implementation, it also includes a fixing plate 160 and a heating device 170. The fixing plate 160 is embedded inside the inner frame 120; the heating device 170 is disposed on the fixing plate 160. Here, the heating device 170 can be a customized induction cooker or electric ceramic cooker with a height of 20mm. The heating device 170 can be used for eating hot pot, hot dishes, hot soup, etc., reducing the need to run back and forth between the kitchen and the dining table when eating, and improving the user experience.

[0043] As an optional implementation, the inner frame 120 is provided with a bearing turntable 180 located on the fixed plate 160, and the heating device 170 is located in the inner ring of the bearing turntable 180. The bearing turntable 180 can enable the table to rotate to meet different usage needs.

[0044] Example 2

[0045] Reference Figures 1-8 This embodiment provides a dining table, including the aforementioned lifting mechanism. The dining table includes a backing plate 210, with an outer frame 110 embedded within the backing plate 210. Fan-shaped panels 220 are provided on both sides of the top surface of the backing plate 210, and a rotatable tabletop 230 is also provided on the top surface of the backing plate 210. The tabletop 230 can be rotated to form a circular tabletop with the two fan-shaped panels 220. A mounting bracket 240 is provided at the bottom of the backing plate 210, and a handle 250 is hinged within the mounting bracket 240. One end of the handle 250 is connected to a pull cable 130. Multiple support legs 260 are connected to the bottom of the backing plate 210.

[0046] In this embodiment, the lever principle can be used to manually swing the handle 250 to drive the pull cable 130 to rotate, which is labor-saving and drives the inner frame 120 to rise. Here, the tabletop 230 can be rotated through the bearing turntable 180. When the inner frame 120 is raised, the tabletop 230 can be raised to a certain height. At this time, the tabletop 230 can be rotated to overlap the top surface of the fan-shaped panels 220 on both sides. At this time, the pull cable 130 can be released, and the tabletop 230 is supported on the top surface of the fan-shaped panels 220. At this time, the table is the size of the tabletop 230, thereby reducing the table area to accommodate a small number of diners. The tabletop 230 has two straight ends, which can be fitted to the wall to further reduce space and make it flexible to use. When there are many diners, the tabletop 230 can be rotated to form a circular tabletop with the two fan-shaped panels 220. At this time, the inner frame 120 will sink under the weight of the tabletop 230 so that the top surface of the tabletop 230 is flush with the top surface of the two fan-shaped panels 220, thus forming a complete circular tabletop. It is flexible in use and can meet various usage needs.

[0047] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
