The shutter comprises a shutter body which comprises inner glass, outer glass, a shutter frame pipe and a sealing rubber strip, the pressure balance valve structure comprises a valve seat, a valve plate and a valve cover, the valve seat is arranged in a shutter frame pipe cavity, the valve seat forms a valve plate containing cavity, an air incoming hole is formed in the cavity bottom wall of the valve plate containing cavity, a group of valve plate shelving flanges are formed on the cavity bottom wall of the valve plate containing cavity, and the valve plate is shelved on the valve plate containing flanges; the valve cover is positioned in the shutter frame pipe cavity, the valve cover forms a valve seat matching cavity, a ventilation pipe extends on one side, facing the sealing rubber strip, of the valve cover, passes by the shutter frame pipe wall on one side, facing the sealing rubber strip, of the shutter frame pipe to tap into the sealing rubber strip and is communicated with the outside, and one side, facing a ventilation pipe hole, of the valve plate contacts with the valve cover cavity wall in an adhered manner. The pressure balance valve structure is high in elusiveness, thereby being capable of avoiding damage caused by artificial contact, convenient to manufacture and mount, ideal in self-adjusting effect, convenient and quick to mount and capable of avoiding damage to glass.

The invention discloses a sand painting design device, which comprises a support platform, a first groove is opened on the top, and a plurality of backlights are arranged in the first groove; a sand table is arranged in the first groove, and the top surface of the sand table is It is flush with the top surface of the support platform, and two first magnets are arranged on the outer periphery of the sand table; the template fixing frame is provided with a hollow template, and the bottom of the template fixing frame is provided with a second magnet opposite to the two first magnets , there is also a shielding device on the formwork fixing frame below the hollow formwork; there are at least two support columns, which are symmetrically arranged on the support platform, and a mounting frame is provided on the top of the support column, and a linear motor and a connecting plate are arranged in the mounting frame. The mover of the linear motor is connected to one end of the conveying pipe, and the other end of the conveying pipe is slidably connected to the connecting plate; the sand feeding hopper, the discharge port is connected to the conveying pipe, and the conveying pipe is provided with a plurality of through holes for sand spraying ; The present invention can be applicable to the public that does not possess artistic skill, has market prospect more.

The embodiment of the invention provides a content display method and device. The method comprises: when a target content is displayed on a liquid crystal display panel, obtaining a pre-assigned original gray scale for displaying the target content; determining whether the obtained original gray scale is smaller than a preset gray scale or not; if the obtained original gray scale is smaller than the preset gray scale, determining a target gray scale corresponding to the obtained original gray scale according to a corresponding relation between the pre-assigned original gray scale and the target gray scale, wherein a target gray scale in each record in the corresponding relation between the pre-assigned original gray scale and the target gray scale is larger than the original gray scale; and displaying the target content on the liquid crystal display panel with the target gray scale. Compared to displaying of a target content on a liquid crystal display panel with an original gray scale, the content display method and device can display a content on the liquid crystal display panel with a higher target gray scale than the original gray scale to eliminate a light leakage phenomenon,avoid influence on users' watching effects and avoid reduction of users' watching experiences.

The invention discloses a 3D light show drone device and a method of use thereof, including a driving mechanism, a central mechanism and a connecting mechanism. The four corners of the central mechanism are rotatably connected to a vertically established driving mechanism through the connecting mechanism. The central mechanism includes a body, and a first stepping motor is embedded in the center of the top surface of the body, and the first stepping motor is connected with a winding wheel through a motor shaft transmission. In the present invention, the central mechanism drives the connecting mechanism to turn outward through the first torsion spring, and the connecting mechanism turns outward through the second torsion spring to drive the driving mechanism. Realize the support and suspension of the traction rope, avoiding the impact of light on the supporting legs during the light show of the 3D light show drone device, affecting the viewing effect of the audience watching at close range.

The invention relates to the technical field of non-medical health information consultation, and discloses a hidden night cleaning device for exhibitions based on the principle of photoresistors, including an exhibition frame, the top of which is fixedly connected with a top frame; the function of the light frame , save power, and automatically illuminate, increase the attractiveness of the display cabinet, and make the turntable rotate to provide power for subsequent cleaning operations. The rotation of the first rotating rod causes the cleaning rod to be placed horizontally or vertically, and the sanitary ware is automatically retracted , which is conducive to the cleaning operation. In the non-use state, the sanitary ware is hidden, and the rotation of the second rotating frame causes the cleaning plate to move up and down, automatically cleaning the display screen at night, increasing the clarity of the exhibition to avoid dust and stains The contamination will affect the viewing effect, and avoid cleaning during the day, which will affect people's viewing, free hands, reduce the workload of cleaning personnel, and have a high degree of automation.

A vehicle-mounted movable studio comprises a vehicle body. A vertical first rotating shaft with a power device is fixedly installed in the middle of the top of a vehicle hopper of the vehicle body. Two horizontal connecting rods are fixedly installed at the top end of the first rotating shaft and symmetrically distributed with the first rotating shaft as the center. The opposite side ends of the two connecting rods are each movably provided with a slide rod. Two horizontal supporting plates are arranged above the vehicle hopper of the vehicle body. Fixed rods are fixedly installed on the opposite sides of the two supporting plates respectively and are parallel to each other. A first through groove is formed in the top side of each fixed rod. Each slide block can be inserted in the corresponding first through groove and slide along the first through groove. The length of a projection screen can be controlled, projections of different image sizes can all be displayed on the projection screen, light can be shielded for the projection screen through a telescopic plate, it is avoided that in the day, images projected on the projection cloth are not clear due to light and other reasons,and it is avoided that the watching effect is influenced.
