Description

Technical Field

[0001] The invention belongs to the technical field of medical supplies, and in particular relates to a multifunctional table for community physical examination. Background Art

[0002] A community is a large collective of people who are interconnected in life and formed by a number of social groups or social organizations gathered in a certain area. It is the most basic content of a social organism and a microcosm of the macro society. A community is a community and its activity area formed by people who are interconnected in a certain area with some kind of interactive relationship and common cultural ties.

[0003] Medical staff often go to communities to conduct physical examinations on community residents. When conducting physical examinations on community residents, they need to assemble a long table, with medical staff sitting on one side and physical examination personnel sitting on the other side to conduct routine examinations such as blood routine and blood pressure measurement on community residents. Before the examination, preparation personnel need to pack up multiple tables for assembly to facilitate the use of medical staff. However, when packing up, the original items need to be placed aside, which is not only troublesome to operate, but also easy to cause the original items to be lost. In addition, after the physical examination is completed, medical staff need to observe the physical examination report. When observing, they need to continue holding it or placing it on the table, which imposes a heavy workload on medical staff. Therefore, there is an urgent need for a multifunctional table for community physical examination that can effectively and conveniently be used by medical staff. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a multifunctional table for community physical examination, which effectively solves the problems of inconvenient assembly of existing physical examination tables and inconvenience in use by medical staff.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a multifunctional table for community physical examination, including a main table, a foldable and unfoldable folding table is connected to the main table, universal wheels are provided on the main table and the folding table, and a viewing device is provided at one end of the main table away from the folding table; the main table is also provided with a transmission device connected to the viewing device, and the main table is provided with a driving structure connected to the transmission device, the driving structure is connected to the folding table, the driving structure can drive the folding table to move up and down, the transmission device drives the viewing device to move when it rotates forward, and drives the driving structure to move when it rotates reversely; the viewing device includes a rotating folding structure connected to the transmission device, the rotating folding structure is connected to a pair of viewing panels, and the rotating folding structure can drive a pair of folding panels to rotate and fold during the rotation process.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] When the present invention is in use, by setting up a folding table, it can effectively avoid the preparation personnel from tidying up the other tables for use, and when the present invention is used normally, it can also be used as a normal table, thereby improving the convenience of the present invention; by setting up a viewing device, the physical examination report after the examination can be handed over to the medical staff sitting at the main table for viewing. When viewing, the medical staff puts the physical examination report on a pair of folding boards, views it, and then analyzes it. Setting up the viewing device can effectively reduce the labor intensity of the medical staff. BRIEF DESCRIPTION OF THE DRAWINGS
