Problems solved by technology

[0002] Current furniture (electric heating tables, chairs, folding dining tables, etc.), medical equipment (folding hospital beds, medical testing equipment, etc.), office equipment, teaching equipment and other equipment are equipped with multiple stressed parts and multiple power These components are independently driven by a separate power device, and finally controlled by the control system to move synchronously, such as a variable-sized round dining table, which uses multiple independent air rods to drive multiple fan-shaped plates on the round dining table Folding or unfolding, but the above structure has problems such as high cost, poor synchronization, and complicated installation

Embodiment 1

[0044] Embodiment one, such as Figure 1 to Figure 21 As shown, an electric heating table includes a panel 81, a base plate 83, a controller (not shown) and four table legs 82, the panel 81 is located above the base plate 83, and the tops of the four table legs 82 are connected to The bottom of the panel 81 is connected, the bottom ends of the four table legs 82 are connected with the bottom plate 83 , and the controller is arranged on the panel 81 . The bottom of the panel 81 is provided with a heating device 9, the heating device 9 includes a mounting plate 911, a mounting frame 91, four heating boxes 90 and a synchronous telescopic transmission device 1, and the mounting plate 911 is fixedly connected to the four table legs and located below the panel 81, the installation frame 91 is provided on the bottom of the installation plate 911, of course, the installation frame 91 can also be directly fixedly connected to the bottom of the panel 81 (omitting the installation plate ...

Embodiment 2

[0072] Embodiment 2. Embodiment 2 is similar to Embodiment 1. The only difference is that the driving structure of the synchronous telescopic transmission device in Embodiment 2 is a driving arc-shaped protrusion, which is in the shape of a plane spiral , the driven structure 61 corresponds to a driven groove, and the driving arc-shaped protrusion is concave-convex matched with the driven groove. The driving arc-shaped protrusion in this embodiment is arranged on the bottom surface of the turntable 4, and the driven concave The groove is formed by opening a middle groove on the top of the driven protrusion on the slider 6 in the first embodiment, and the driving arc-shaped protrusion is inserted downward into the middle groove to realize the cooperation of the upper and lower concave-convex, and the driving arc-shaped protrusion It is also a sliding fit with the middle groove. When the turntable 4 rotates forward or reversely, the driving arc-shaped protrusion drives the multip...

Abstract

The invention relates to a transmission device capable of achieving synchronous outstretching and backdrawing. The transmission device comprises a base, a rotary table, a rotary center shaft and at least two slide blocks, wherein the rotary table is rotatably arranged on the base, the slide blocks are linearly and slidably arranged on the base, driving structures in a planar spiral shape are arranged on the rotary table, driven structures are arranged on the slide blocks, the rotary center shaft is in transmission connection with the rotary table, the driving structures are in sliding fit withthe driven structures, the rotary center shaft drives the rotary table to rotate, the driving structures drive the driven structures to slide along a straight line, and thus the slide blocks are driven to simultaneously stretch out of the base or draw back into the base. According to the transmission device capable of achieving synchronous outstretching and backdrawing, through forward rotation or reverse rotation of the rotary table, the driving structures on the rotary table drive the multiple slide blocks to slide in or out of the base simultaneously, so that the slide blocks synchronouslydraw back into or stretch out of the base, and can then drive synchronous action of a plurality of parts. Therefore, the transmission device is very convenient to control, simple in structure, low incost and convenient to install.
