Description

Technical Field

[0001] This utility model relates to the field of office furniture technology, and in particular to a conference chair with a support plate. Background Technology

[0002] Conference chairs, as an indispensable piece of office furniture in conference settings, are mainly used to provide seating support for participants. Their structure typically includes basic components such as a base, support shaft, seat, and backrest. Some conference chairs also have auxiliary structures such as armrests added according to usage needs to improve the comfort of participants and meet the needs of long-term meetings. They are widely used in corporate conference rooms, seminar rooms of public institutions, hotel conference centers, and other venues. In existing technologies, most traditional conference chairs only provide seating support and lack a dedicated structure for placing meeting materials. During meetings, if attendees need to access documents, take notes, or place tablets, laptops, or other items, they often have to place these items on their laps, on the conference table (which is unusable if there are insufficient tables or the seats are too far from the table), or hold them in their hands. This not only increases the risk of items falling or being lost but also increases physical strain and affects concentration. Furthermore, some conference chairs with simple storage structures often have fixed designs that cannot be adjusted for tilt angles or unfolding positions based on attendees' habits and needs. They also lack storage functionality, taking up extra space when the storage structure is not in use and even affecting posture adjustment and ease of movement, making it difficult to meet the diverse needs of meeting scenarios. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a conference chair with a support plate.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A conference chair with a tray includes a base, a support shaft, a seat, and a tray. A fixing block is fixedly mounted on the support shaft. Fixing sleeves are fixedly mounted on both the tray and the fixing block. A connecting rod is provided between the upper and lower fixing sleeves. The connecting rod has a first pressing groove. A first positioning block is provided in the first pressing groove through a first pressing mechanism. The fixing sleeve has multiple first positioning holes. The tray has a storage groove. A movable plate is provided in the storage groove. The movable plate has a placement groove and a second pressing groove. A second positioning block is provided in the second pressing groove through a second pressing mechanism.

[0005] Preferably, the first extrusion mechanism includes a first spring disposed in the first extrusion groove, and the two ends of the first spring are respectively connected to the inner wall of the first extrusion groove and the first positioning block.

[0006] Preferably, the second extrusion mechanism includes a second spring disposed in the second extrusion groove, with both ends of the second spring connected to the inner wall of the second extrusion groove and the outer wall of the second positioning block, respectively.

[0007] Preferably, the fixed sleeve has six first positioning holes, which are evenly spaced circumferentially.

[0008] Preferably, each side of the tray has two second positioning holes, and both second positioning holes are regular hexagonal holes.

[0009] Preferably, the second extrusion groove is a regular hexagonal groove, and the second positioning block is a regular hexagonal prism.

[0010] The beneficial effects of this utility model are: This invention achieves flexible adjustment of the tray's tilt angle by setting a fixing block on the support shaft, in conjunction with a connecting rod, a fixing sleeve, and a first pressing mechanism. Utilizing the pressing action of the first spring on the first positioning block, the tilt angle of the connecting rod and the tray can be easily adjusted by changing the first positioning hole into which the first positioning block is inserted, thus meeting the personalized needs of different participants for the tray's usage angle and improving its flexibility.

[0011] The tray features a storage slot and a movable panel. Combined with a second pressing mechanism, the movable panel can switch between two states: unfolded and tilted for use, and folded up. When unfolded, the movable panel is tilted, and its placement slot can stably hold meeting materials for easy access by attendees. When folded up, the movable panel can be completely retracted into the storage slot, without occupying extra space and avoiding interference with personnel activities.

[0012] When the connecting rod and the support plate are in a horizontal position and the movable plate is folded up, the support plate can be used as a footrest, realizing the versatility of the structure and further expanding the application scenarios of the conference chair. There is no need to equip it with additional footrests or other auxiliary items, thus reducing office costs. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-9 A conference chair with a tray includes a base 1, a support shaft 2, a seat 4, and a tray 5. A fixing block 3 is fixedly mounted on the support shaft 2. Fixing sleeves 6 are fixedly mounted on both the tray 5 and the fixing block 3. A connecting rod 7 is provided between the upper and lower fixing sleeves 6. The connecting rod 7 is provided with a first extrusion groove 12. A first positioning block 13 is provided in the first extrusion groove 12 through a first extrusion mechanism. A plurality of first positioning holes 8 are provided on the fixing sleeve 6. A storage groove 9 is provided on the tray 5. A movable plate 10 is provided in the storage groove 9. A placement groove 18 and a second extrusion groove 15 are provided on the movable plate 10. A second positioning block 16 is provided in the second extrusion groove 15 through a second extrusion mechanism.

[0017] The first extrusion mechanism includes a first spring 14 disposed within the first extrusion groove 12, with both ends of the first spring 14 connected to the inner wall of the first extrusion groove 12 and the first positioning block 13, respectively. The elastic potential energy provided by the first spring 14 enables the extrusion of the first positioning block 13, allowing the first positioning block 13 to be squeezed into the current first positioning hole 8 without strong external force intervention.

[0018] The second extrusion mechanism includes a second spring 17 disposed within the second extrusion groove 15. The two ends of the second spring 17 are respectively connected to the inner wall of the second extrusion groove 15 and the outer wall of the second positioning block 16. The elastic potential energy provided by the second spring 17 enables the extrusion of the second positioning block 16, allowing the second positioning block 16 to be squeezed into the current second positioning hole 11 without strong external force intervention.

[0019] The fixed sleeve 6 has six first positioning holes 8, which are evenly spaced circumferentially. This design allows the connecting rod 7 to be rotated relative to the fixed block 3, with a single rotation adjustment angle of 60 degrees.

[0020] Each side of the tray 5 has two second positioning holes 11, both of which are regular hexagonal holes. With this design, the movable plate 10 can be stored in the storage slot 9 on the tray 5, or, as shown in the figure, can be unfolded and tilted to facilitate the user to place materials into the placement slot 18.

[0021] The second extrusion groove 15 is a regular hexagonal groove, and the second positioning block 16 is a regular hexagonal prism. It is precisely because of the above shape design that the movable plate 10 can be rotated and adjusted relative to the support plate 5, with a single rotation angle of 60 degrees.

[0022] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

[0023] When this utility model is in use, the tray 5 is positioned above the base 1, and two connecting rods 7 are installed. One end is inserted into the fixing sleeve 6 on the fixing block 3, and the other end is inserted into the fixing sleeve 6 on the tray 5. The first positioning block 13 can enter any first positioning hole 8 on the fixing sleeve 6 under the squeezing action of the first spring 14. By changing the first positioning hole 8, the tilt angle of the connecting rod 7 and the tilt angle of the tray 5 can be changed.

[0024] Then, after the movable plate 10 is dragged out and tilted at a certain angle, the second positioning block 16 enters the second positioning hole 11 near the opening of the storage slot 9 under the action of the second spring 17. At this time, the movable plate 10 is tilted as shown in the figure, and some materials can be put into the placement slot 18 for use by the user.

[0025] In this design, when the connecting rod 7 is approximately horizontal and the support plate 5 is also approximately horizontal, the specific details are as follows: Figure 9 When the movable plate 10 is stored in the storage slot 9 as shown, the aforementioned tray 5 can be used as a footrest.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
