Description

Technical Field

[0001] This application relates to the technical field of conference speeches, and in particular to a retractable lectern. Background Art

[0002] A conference refers to an organized, led, and purposeful deliberative activity, which is carried out according to a certain procedure within a limited time and place. Conferences are a common social phenomenon, and a lectern is often used when chairing a conference.

[0003] Currently, the lectern is either integrally formed and moved to the stage surface by a special person during use and then moved off the stage after use; or it is fixedly set on the stage surface, which will fixedly occupy a part of the space on the stage surface. In both cases, there are obvious deficiencies: First, the lectern is exposed for a long time and is prone to dust contamination. Especially for some lecterns with electronic devices, long-term dust contamination will make the electronic devices more likely to be damaged, and even easily damaged by external objects. Second, the lectern that is not fixed on the stage surface requires a special person to carry it, which is time-consuming and laborious. Third, the lectern fixed on the stage surface will fixedly occupy a certain space, resulting in waste of space. Summary of the Utility Model

[0004] In order to effectively solve the problems of requiring a special person to carry, being exposed to dust space for a long time, and fixedly occupying a part of the tabletop space, this application provides a retractable lectern system.

[0005] The retractable lectern system provided by this application adopts the following technical solutions:

[0006] A retractable lectern system includes a frame, a lectern component, and a folding component;

[0007] The folding component includes a first tabletop. There is a gap between the outer frame of the lectern component and the inner frame of the frame. The lectern component is hinged to the first tabletop and the frame respectively to extend or retract from the frame.

[0008] By adopting the above technical solutions, when the lectern component is needed, the lectern component can be extended from the frame through the cooperation of the hinged connections of the lectern component with the first tabletop and the frame respectively. When the lectern component is not needed, the lectern component can be retracted into the frame through the reverse steps, so as to reduce the time for the lectern component to be exposed and save the space on the stage surface, and at the same time, no special person is required to carry it.

[0009] Furthermore, to better implement the present application, the following structural settings are specifically adopted: The folding assembly further includes a first adjusting member and a second adjusting member, which are hinged at their respective non-end positions and can rotate relative to each other;

[0010] One end of the first adjusting member is hinged to the frame, and one end of the second adjusting member is hinged to the first tabletop. The hinge positions of one end of the first adjusting member with the frame and one end of the second adjusting member with the first tabletop are both on the same side of the frame lengthwise, close to or away from the lectern assembly;

[0011] The other end of the first adjusting member is slidably connected to the first tabletop, and the other end of the second adjusting member is slidably connected to the frame.

[0012] By adopting the above technical solution, both the hinge connection and the sliding connection are common connection methods, which are convenient for processing and have high efficiency on the premise of being able to complete the folding function.

[0013] Furthermore, to better implement the present application, the following structural settings are specifically adopted: The folding assembly further includes a third adjusting member. The other end of the second adjusting member is hinged to the third adjusting member, and the third adjusting member is slidably connected to the frame;

[0014] The folding assembly further includes a lead screw. A first lead screw base is installed on the frame between one end of the first adjusting member and the third adjusting member. A second lead screw base is installed on the third adjusting member. A bearing is installed on the first lead screw base. A nut with an internal thread matching the external thread of the lead screw is installed on the second lead screw base. One end of the lead screw passes through the nut and is connected to the bearing.

[0015] By adopting the above technical solution, the folding of the first adjusting member and the second adjusting member can be adjusted by rotating the other end of the lead screw forward or backward manually or by machine, thereby adjusting the extension and retraction of the lectern assembly.

[0016] Furthermore, to better implement the present application, the following structural settings are specifically adopted: The other end of the lead screw is connected to a driving device.

[0017] By adopting the above technical solution, using the driving device (a machine) to rotate the lead screw saves manpower and improves efficiency.

[0018] Furthermore, to better implement the present application, the following structural settings are specifically adopted: The driving device is a servo reduction motor.

[0019] By adopting the above technical solution, multiple servo reduction motors can be connected in parallel. When multiple lecterns are required on the stage, multiple lectern components can be controlled to lift simultaneously or non-simultaneously through programming to achieve a certain visual effect.

[0020] Furthermore, to better implement the present application, the following structural settings are particularly adopted: connecting plates are installed on both the first lead screw base and the second lead screw base, and an elastic member is installed between the connecting plates.

[0021] By adopting the above technical solution, since the lectern component is relatively heavy, when initially extending the lectern component out of the frame by means of a driving device or manually rotating the lead screw, a relatively large force is often required. At this time, the contraction force of the elastic member is used to provide a certain amount of assistance.

[0022] Furthermore, to better implement the present application, the following structural settings are particularly adopted: the elastic member is a spring.

[0023] By adopting the above technical solution, the spring is a relatively common elastic member, and it is relatively convenient to purchase, install, and replace.

[0024] Furthermore, to better implement the present application, the following structural settings are particularly adopted: the lectern component includes a second tabletop, a contact member is provided on the second tabletop, and a matching contact groove is provided on the upper surface of the frame.

[0025] By adopting the above technical solution, when the lectern component retracts into the frame, the second tabletop is the surface exposed on the stage floor, and people may walk back and forth on the second tabletop. The cooperation between the contact member and the contact groove can play a role in providing strength support.

[0026] Furthermore, to better implement the present application, the following structural settings are particularly adopted: the lectern component further includes a display screen.

[0027] By adopting the above technical solution, relevant information such as meeting information or meeting content can be presented in an electronic display or non-electronic display manner for the participants to view.

[0028] Furthermore, to better implement the present application, the following structural settings are particularly adopted: the lectern component further includes a third tabletop, and a groove and a control panel are provided on the third tabletop.

[0029] By adopting the above technical solution, it is convenient for the user to place items and control the extension, retraction or other devices of the lectern component.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. By setting the lectern component to be hinged to the first tabletop and the frame respectively, the lectern component can be extended or retracted from the frame, achieving the effects and goals of reducing the exposure time of the lectern component and saving space on the tabletop;

[0032] 2. By setting the hinge connection or sliding connection between the first adjusting member, the second adjusting member and the first tabletop, the design and processing technology are simple and efficient;

[0033] 3. By setting the screw drive and the servo reduction motor, it is more convenient to operate the extension and retraction of the lectern component, and at the same time has a certain visual effect;

[0034] 4. By setting the abutting member and the abutting groove, when the lectern component is retracted into the frame, it provides strong support when people walk on the second tabletop and no danger will occur;

[0035] 5. By setting the spring, when the lectern component is extended from the frame by the driving device or manually turning the screw at the beginning, a relatively large force is often required. At this time, the contraction force of the elastic component provides a certain amount of assistance;

[0036] 6. By setting the display screen, the groove and the control panel, it is convenient for the participants to attend the meeting. Description of the Drawings

There are four abutting members 24 and four abutment grooves 15; a groove 25 and a control panel 26 are provided on the third tabletop 22, which can facilitate the user to place items and control the extension, retraction, or other devices of the lectern assembly 2; the display screen 23 can display relevant information such as conference information or conference content through electronic display or non-electronic display for the participants to view.

[0047] The folding assembly 3 includes a first tabletop 31, a first adjusting member 32, a second adjusting member 33, a third adjusting member 34, a lead screw 35, a first lead screw base 36, a second lead screw base 341, a bearing 361, a nut 342, a connecting member 37, and an elastic member 38 (a spring in this embodiment). There is a gap between the outer frame of the first tabletop 31 and the inner frame of the upper top frame 11 of the frame; the first adjusting member 32 and the second adjusting member 33 are hinged at their respective non-end positions and can rotate relative to each other. In this embodiment, the hinged position is the middle position. One end of the first adjusting member 32 is hinged to the lower bottom frame 12 of the frame near the left side frame 13 of the frame, and one end of the second adjusting member 33 is hinged to the first tabletop 31 near the left side frame 13 of the frame; a first chute 311 is provided in the inner frame of the first tabletop 31 near the right side frame 14 of the frame, and the other end of the first adjusting member 32 is slidably connected to the first chute 311; a second chute 121 is provided in the inner frame of the lower bottom frame 12 of the frame near the right side frame 14 of the frame, and the third adjusting member 34 is slidably connected to the second chute 121. The other end of the second adjusting member 33 is hinged to the end of the third adjusting member 34 away from the right side frame 14 of the frame; a first lead screw base 36 is fixedly installed on the lower bottom frame 12 of the frame between one end of the first adjusting member 32 and the third adjusting member 34. A bearing 361 is fixedly installed on the first lead screw base 36. A second lead screw base 341 is fixedly installed on the third adjusting member 34. A nut 342 with an internal thread matching the external thread of the lead screw 35 is fixedly installed on the second lead screw base 341. One end of the lead screw 35 passes through the nut 342 and is connected to the bearing 361; connecting plates are installed on both the first lead screw base 36 and the second lead screw base 341, and a spring is installed between the connecting plates; the other end of the lead screw 35 is connected to a servo reduction motor for driving the forward and reverse rotation of the lead screw 35.

[0048] The implementation method of a retractable lectern system according to an embodiment of the present application is as follows: Refer to Figures 1 - 5, first, a slot for accommodating the telescopic podium system is opened on the stage surface, and the entire telescopic podium system is placed into the slot. At this time, both the other end of the third adjusting member 34 and the other end of the first adjusting member 32 are close to the right frame 14 of the frame 1. The podium assembly 2 is in the retracted state, and the second tabletop 21 is flush with the stage surface. Moreover, under the action of the abutting member 24 and the abutting groove 15, the bearing capacity of the second tabletop 21 is strong and can withstand the movement of people. Start the servo reduction motor. Under the dual action of the servo reduction motor and the spring, the lead screw 35 drives the third adjusting member 34 to move towards the position close to the left frame 13 of the frame. At the same time, since neither one end of the first adjusting member 32 nor one end of the second adjusting member 33 undergoes displacement, and the first adjusting member 32 and the second adjusting member 33 rotate relative to each other due to their hinged connection, the other end of the first adjusting member 32 and one end of the second adjusting member 33 drive the first tabletop 31 to rise. At the same time, since the podium assembly 2 is respectively hinged to the upper top frame 11 of the frame 1 and the first tabletop 31, the podium assembly 2 rotates around the upper top frame 11 of the frame 1, thereby producing an extended effect. When the podium assembly 2 extends out of the stage surface in the final state, the display screen 23 is perpendicular to the upper top frame 11 of the frame and the first tabletop 31 is flush with the stage surface. At this time, the top end of the display screen 23 is higher than the top end of the second tabletop 21 in the horizontal direction, that is, the third tabletop 22 is in an inclined state, which is convenient for the user to operate. If it is no longer in use, the servo reduction motor can be operated to reverse the lead screw 35, so as to retract the podium assembly 2 into the frame 1.

[0049] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
