Description

Technical Field

[0001] The utility model relates to the technical field of video desks, in particular to a video desk with a dust-proof function. Background Art

[0002] The video display stand is also called an object display stand, an object demonstrator, an object projector, an object projector, etc. The video display stand is a demonstration device that converts information such as objects, documents, pictures, and processes into image signals through a CCD camera based on optoelectronic conversion technology and outputs them on display devices such as projectors and monitors for display.

[0003] When the existing video display stand is not in use, the camera and the fixing frame on the surface will be folded and stored on the surface of the bottom plate. However, when the video display stand is placed for a long time, a large amount of dust will accumulate on the surface, and the dust will affect the imaging effect of the camera. For this reason, we propose a video display stand with a dust-proof function to solve the above problems. Summary of the Utility Model

One end of the first pleated cloth is fixedly connected to the upper part of the installation bottom frame, and the other end of the first pleated cloth is fixedly connected to a driving frame. Two fixed cross plates are fixedly connected to the upper part on both sides of the driving frame, and one end of a second pleated cloth is fixedly connected to the side of the fixed cross plate. The other end of the second pleated cloth is fixedly connected to a pulling rod. By unfolding the first pleated cloth and the second pleated cloth, the video display camera and the fixed base can be conveniently shielded and protected.

[0009] Preferably, the surface length of the pulling rod is the same as the surface width of the driving frame. A guiding slider is fixedly connected below the pulling rod, and a sliding groove adapted to the guiding slider is formed on the upper surface of the driving frame. The guiding slider can facilitate the guiding and limiting of the pulling rod.

[0010] Preferably, the supporting mechanism includes a hinged strut. One end of the hinged strut is hinged to the outside of the installation bottom frame, and the other end of the hinged strut is hinged with a moving slider. The moving slider is inserted into the guiding rod. The hinged strut can drive the moving slider to move.

[0011] Preferably, the limiting mechanism includes a guiding stud. The guiding stud is fixedly connected to the outside of the moving slider, and an extrusion nut sleeve is threadedly sleeved on the outer end of the guiding stud. The extrusion nut sleeve can be conveniently sleeved on the surface of the guiding stud to facilitate the limiting of the moving slider.

[0012] Preferably, the guiding rod is fixedly connected to the outside of the driving frame, and a strip-shaped through groove adapted to the guiding stud is formed on the outside of the guiding rod. The strip-shaped through groove formed on the outside of the guiding rod can facilitate the movement of the guiding stud.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The device can conveniently install the first pleated cloth and the driving frame on the outside of the fixed base through the installation mechanism. By pulling the driving frame, the first pleated cloth can be unfolded to shield and protect the four sides of the video display camera and the fixed base. At the same time, by pulling the pulling rod, the guiding slider can slide along the inside of the driving frame, facilitating the second pleated cloth to drive the fixed cross plate to unfold, which is convenient for covering and shielding the upper part of the driving frame. It effectively facilitates the dust-proof function when the video display camera and the fixed base are not in use.

[0015] 2. By pulling the driving frame, the moving slider can slide along the inside of the guiding rod. At this time, the two hinged struts can be unfolded to connect and support the driving frame. At the same time, by rotating the extrusion nut sleeve, the extrusion nut sleeve can be pressed against the surface of the guiding rod to facilitate the limiting of the moving slider and the fixation of the two hinged struts.
