DETAILED DESCRIPTION
[0028] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.
[0029] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.
[0031] As attached Figure 1-5 An integrated computer desk shown in the figure comprises a support frame 1, a table body 2, a flip cover 3 and a detection mechanism 4, wherein the table body 2 is fixedly connected to the upper end of the support frame 1, the flip cover 3 is rotatably connected to the upper surface of the table body 2, the detection mechanism 4 is rotatably connected to the flip cover 3, and is used to detect whether the display and the display bracket are compatible, a mounting cavity 34 is provided on the side of the flip cover 3 close to the table body 2, and is used to install the display, the flip cover 3 comprises side panels 31 symmetrically arranged on the left and right and a front panel 32 connecting the two side panels 31, and a connecting mechanism 91 is used to connect the display and the flip cover 3,
[0032] The detection mechanism 4 includes two groups of symmetrically arranged first connecting plates 41, second connecting plates 42 and first detection plates 43. The second connecting plates 42 connect the first connecting plates 41 and the first detection plates 43. A fixing portion 33 protrudes outward from the front plate 32. The fixing portion 33 is used to fix the two first detection plates 43.
[0033] When the detection mechanism 4 is not in a working state, the first connecting plate 41 and the second connecting plate 42 are disposed in close contact with the side plate 31, and the first detection plate 43 is disposed in close contact with the front plate 32;
[0034] When the detection mechanism 4 is in working state, the detection mechanism 4 is folded toward the table body 2, the first connecting plate 41 is arranged parallel to the side plate 31, and the second connecting plate 42 and the first detection plate 43 are arranged perpendicular to the side plate 31. The length of the two second connecting plates 42 along the horizontal direction is equal to the length of the fixing portion 33 along the horizontal direction.
[0035] The present invention can detect whether the display and the display connector are adapted to the integrated computer table of the present invention through the setting of the detection mechanism 4. If the two first detection plates 43 can be docked and the two first detection plates 43 are both arranged vertically with the second connection plate 42, the display will not collide during the flipping process. The display and the display connector are adapted to the integrated computer table of the present invention, and there is no need to detect whether the display and the display connector are adapted when flipping and closing. This can effectively solve the problem that when the integrated computer table is adapted to different brands of displays, the display will collide or close and get stuck when the flip cover of the integrated computer table is closed due to the different sizes of the display and the display connector. This can effectively protect the display and the integrated computer table of the present invention, and increase the practicality of the present invention. At the same time, after the detection is completed, the detection mechanism 4 can be kept in working condition to protect the display and avoid the adhesion of dust and other impurities.

If the active card buckle 6 on the first detection plate 43 can be completely engaged with the fixed card slot 7 on the first detection plate 43, it is proved that the display and the display connector are adapted to the integrated computer table of the present invention. In addition, when the detection mechanism 4 is in a non-working state, the two first detection plates 43 can be fixedly connected with the flip cover 3 to store the detection mechanism 4. The setting of the arc surface with a central angle greater than 180 degrees of the limiting portion 64 can ensure the card connection effect, limit the first detection plate 43, and avoid disengagement.
