Description

Technical Field

[0001] The utility model relates to the technical field of installation of a dome theater screen, in particular to a dome theater screen installation device. Background Art

[0002] A dome theater is a type of cinema that uses a spherical screen and advanced projection technology to create an immersive viewing experience. The audience is surrounded by a huge spherical screen and can enjoy almost no blind spot visual effects, thus gaining an immersive viewing experience. Dome theaters are usually used to play special effects movies, documentaries, live concerts, etc., and can provide a more shocking and immersive viewing experience than traditional flat screens. When the screen is installed, a screen mounting device will be used.

[0003] For example, a dome theater screen installation device disclosed in Chinese patent CN217557563U has a rotating platform arranged inside the outline of the screen and is arranged to rotate around the vertical direction. Therefore, the working platform installed on the rotating platform can also rotate around the vertical direction. When the construction workers stand on the working platform for construction, the construction workers can complete the installation of the annular aluminum strip at the height under the rotation of the working platform. The working platform is provided with multiple layers, and the multiple layers are arranged at intervals, which has the advantage of convenient installation. The installation of the working platform can shorten the time compared with the installation of the scaffolding, so the total construction time can be shortened, and the cost of the working platform is lower than that of the scaffolding. Since the multiple layers of the working platform are arranged at intervals along the height direction, when the construction workers can complete the installation of multiple annular aluminum strips of different heights through one side of the multiple layers of the working platform, the installation of the entire dome theater screen can be realized. Compared with the prior art of installing the screen by setting up a scaffolding by a steel pipe frame, the dome theater screen installation device proposed in this application has the advantages of convenient installation and relatively low cost.

[0004] For this structure, although the screen can be installed, it will rise when being installed. At this time, the installation device needs to be supported to make the installation safer. Therefore, we propose a dome theater screen installation device that can support the installation device to improve the installation stability. Utility Model Content

[0010] Preferably, the bottom of the support plate is made of anti-slip material, and the screw and the slide rod are internally threaded. Under the restriction of the screw, when the screw rotates, the support plate can be pushed to move toward the ground. When the support plate contacts the ground, the screw is then rotated, and it rotates with the support plate, so that the support plate can be firmly contacted with the ground.

[0011] Preferably, the sleeve block is slidably arranged inside the bottom plate, and the sleeve block is threadedly sleeved on the outer wall of the opposing threaded rod. Under the restriction of the opposing threaded rod, the rotating opposing threaded rod drives the sleeve block to move.

[0012] Preferably, there are two protection rods, which are symmetrically distributed about the center line of the platform. Under the protection of the protection rods, the screen can be installed more safely.

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

[0014] 1. The screen installation device of the dome theater is composed of a supporting assembly as one part. When the screen is installed, the installation device is moved to the required position, and the operator is lifted by the lifting mechanism to install the screen. When the installation device is used, in order to make it more stable, it needs to be supported. At this time, the sleeve is rotated, and the sleeve drives the sliding rod to rotate accordingly, and then the screw is rotated to make the screw push the supporting plate to move downward so that the supporting plate contacts the ground. Under the support of the screw and the supporting plate, the installation device is supported. When the terrain is irregular, the plug rod is pulled at this time, and the spring sleeved on the outer wall of the plug rod is compressed. At this time, the plug rod is no longer engaged with the hole opened on the outer wall of the sliding rod. The sliding rod is pulled to pull the sliding rod outward from the sleeve to adjust the support range according to the terrain. When the installation device is used, the installation block is rotated toward the base, so that the first magnetic plate fixedly installed on the outer wall of the sleeve and the second magnetic plate fixedly installed on the outer wall of the base are magnetically attracted to each other, and the installation block is stored to facilitate the movement of the installation device.

[0015] 2. The screen installation device of the dome theater is composed of an expansion component as one part. When installing the screen, the operator stands on the platform. When the screen needs to be installed in other parts, the motor is started at this time, and the opposing threaded rods fixedly installed at its output rotate accordingly. Due to the sliding arrangement of the outer wall of the sleeve block and the inside of the bottom plate, under their restriction, the rotating opposing threaded rods drive the two platforms to move in opposite directions to widen the operator's standing area for installing screens in different positions. When the platforms move in opposite directions, the slide grooves opened on the top surfaces of the platforms slide on the outer walls of the sliders, and the operators are prevented from falling under the protection of the protective rods, thereby improving the safety of the installation.

DETAILED DESCRIPTION

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0024] Example 1

[0025] The preferred embodiment of the installation device for a dome theater screen provided by the utility model is as follows Figures 1 to 6 As shown: a dome theater screen installation device, comprising a base 1;

[0026] A universal wheel 2 is fixedly installed at the bottom of the base 1;

[0027] A lifting mechanism 3 is arranged above the base 1;

[0028] A bottom plate 4 is fixedly mounted above the lifting mechanism 3;

[0029] An armrest 5 is fixedly mounted on the outer wall of the base 1;

[0030] And a processing component 6 arranged outside the lifting mechanism 3, the processing component 6 includes a supporting component 61 arranged outside the base 1, the supporting component 61 includes a mounting block 611 fixedly mounted on the outer wall of the base 1, the inner side of the mounting block 611 is hingedly connected with a sleeve 612, a sliding rod 613 is slidably arranged inside the sleeve 612, a screw 614 is sleeved inside the sliding rod 613, a support plate 615 is rotatably connected to the end of the screw 614, a limiting frame 616 is fixedly mounted on the outer wall of the sleeve 612, an insertion rod 617 is slidably arranged inside the limiting frame 616, a spring 618 is sleeved on the outer wall of the insertion rod 617, a second magnetic plate 620 is fixedly mounted on the outer wall of the base 1, and a first magnetic plate 619 is fixedly mounted on the outer wall of the sleeve 612.

[0031] In this embodiment, when installing the screen, the installation device is moved to the desired position, and the operator is lifted by the lifting mechanism 3 to install the screen. When the installation device is used, in order to make it more stable, it needs to be supported. At this time, the sleeve 612 is rotated, and the sleeve 612 drives the slide bar 613 to rotate accordingly, and then the screw 614 is rotated to make the screw 614 push the support plate 615 to move downward, so that the support plate 615 contacts the ground. Under the support of the screw 614 and the support plate 615, the installation device is supported. When the terrain is irregular, At this time, the plug rod 617 is pulled, and the spring 618 sleeved on the outer wall of the plug rod 617 is compressed. At this time, the plug rod 617 is no longer engaged with the hole opened on the outer wall of the slide bar 613. The slide bar 613 is pulled to pull the slide bar 613 outward from the sleeve 612 to adjust the support range according to the terrain. When the installation device is used, the installation block 611 is rotated toward the base 1, so that the first magnetic plate 619 fixedly installed on the outer wall of the sleeve 612 and the second magnetic plate 620 fixedly installed on the outer wall of the base 1 are magnetically attracted to each other, and the installation block 611 is stored to facilitate the movement of the installation device.

[0032] Furthermore, the insertion rod 617 is arranged inside the limiting frame 616, and holes are opened at equal intervals on the outer wall of the sliding rod 613. Under the clamping restriction of the insertion rod 617 and the sliding rod 613, the sliding rod 613 and the sleeve 612 can be prevented from sliding.

[0033] Furthermore, the bottom of the support plate 615 is made of anti-slip material, and the screw 614 and the sliding rod 613 are internally threaded. Under the restriction of the screw 614, when the screw 614 rotates, the support plate 615 can be pushed to move toward the ground. When the support plate 615 contacts the ground, the screw 614 is then rotated, and it rotates with the support plate 615, so that the support plate 615 can be firmly contacted with the ground.

[0034] Example 2

[0035] Based on Example 1, a preferred embodiment of a dome theater screen installation device provided by the utility model is as follows: Figures 1 to 6 As shown: the expansion component 63 includes a bracket 631 fixedly mounted on the outer wall of the base plate 4, a motor 632 is fixedly mounted on the outer wall of the bracket 631, a counter threaded rod 633 is fixedly mounted on the output end of the motor 632, a sleeve block 634 is sleeved on the outer wall of the counter threaded rod 633, a platform 635 is fixedly mounted on the outer wall of the sleeve block 634, a slide groove 636 is opened on the top surface of the platform 635, a slider 637 is slidably arranged inside the slide groove 636, and a protective rod 638 is fixedly mounted on the outer wall of the slider 637.

[0036] In this embodiment, when installing the screen, the operator stands on the platform 635. When the screen needs to be installed in other parts, the motor 632 is started at this time, and the output of the motor 632 causes the fixedly installed opposing threaded rods 633 to rotate accordingly. Since the outer wall of the sleeve block 634 and the inner sliding arrangement of the bottom plate 4 are set, under their restriction, the rotating opposing threaded rods 633 drive the two platforms 635 to move in the opposite direction to widen the operator's standing area for the installation of screens in different positions. When the platforms 635 move in opposite directions, the slide groove 636 opened on the top surface of the platform 635 slides on the outer wall of the slider 637, and the operator is prevented from falling under the protection of the protective rod 638, so as to improve the safety of the installation.

[0037] Furthermore, the sleeve block 634 is slidably arranged inside the bottom plate 4, and the sleeve block 634 is threadedly sleeved on the outer wall of the opposite threaded rod 633. Under the restriction of the opposite threaded rod 633, the rotating opposite threaded rod 633 drives the sleeve block 634 to move.

[0038] In addition, there are two protection rods 638 symmetrically distributed about the center line of the platform 635 . With the protection of the protection rods 638 , the screen can be installed more safely.
