Description

Technical Field

[0001] The utility model relates to the technical field of projection devices, in particular to a projection device for BIM building planning. Background Art

[0002] A projector is also called a projector. It is a projection optical instrument that provides a large-size screen. On the basis of a direct-projection slide projector, a reflector is added to change the light path so that the image of the slide placed flat on the object glass is projected onto the screen. When viewing BIM building planning information, a projector is needed to project the screen for multiple people to watch.

The projection position has certain limitations, and the height required by the user cannot be adjusted according to the needs of the user. The viewing comfort is low and the best projection effect cannot be achieved. Therefore, we provide a projection device for BIM building planning. Utility Model Content

[0031] See also Figure 1-4 , the embodiments of the utility model will be further described below in conjunction with the accompanying drawings.

[0032] Example

[0033] A technical solution adopted by a projection device for BIM building planning is: it includes a fixed plate 6 and a support rod 4, a driving motor 18 is fixedly installed on the rear end of the top of the fixed plate 6, and the output end of the driving motor 18 is fixedly connected to a threaded rod 2, the surface of the threaded rod 2 is threadedly connected to a threaded sleeve 17, the surface of the threaded sleeve 17 is fixedly connected to a connecting plate 5, and a projector 21 is placed on the top of the connecting plate 5.

[0034] Specifically: when projection work is needed, the user starts the drive motor 18 to work, and the drive motor 18 drives the threaded rod 2 to rotate in the clockwise direction. During the rotation of the threaded rod 2, the threaded sleeve 17 is driven to move upward, and the connecting plate 5 is driven upward by the threaded sleeve 17. The projector 21 is driven upward by the connecting plate 5 and moves to the best viewing height for the user, thereby achieving the height adjustment function. Similarly, the drive motor 18 drives the threaded rod 2 to rotate counterclockwise, and the projector 21 can be driven to move downward.

[0035] The top of one side of the support rod 4 is fixedly connected to the limit plate 3, both sides of the bottom of the connecting plate 5 are fixedly connected to the limit blocks 19, and the limit blocks 19 and the support rod 4 are fixedly connected by mounting bolts 20, the bottom of the fixed plate 6 is fixedly installed with cylinders 9, the bottom of the cylinder 9 is fixedly connected to the cross plate 8, and the front and rear ends of the bottom of the cross plate 8 are movably connected with universal wheels 7, the rear end of the top of the fixed plate 6 is fixedly connected to the support plate 1, and the top of the inner surface of the support plate 1 is fixedly connected to the bearing 12, the top of the threaded rod 2 is fixedly connected to the inner ring of the bearing 12, the center of the bottom of the fixed plate 6 is fixedly connected to the power supply box 14, and the inner cavity of the power supply box 14 is provided with a battery 13, the inner surface of the support plate 1 is provided with a slide groove 15, the back of the threaded sleeve 17 is fixedly connected to the slider 16, and the back of the slider 16 is slidably connected to the inner cavity of the slide groove 15, the two sides of the bottom of the fixed plate 6 are fixedly connected to the support blocks 10, and the bottom of the support block 10 is fixedly connected to the bottom plate 11.

[0036] Specifically: the user picks up the support rod 4, passes the support rod 4 through the top of the connecting plate 5, so that the bottom of the support rod 4 is located below the connecting plate 5 and on one side of the limit block 19, and the inner surface of the limit plate 3 is fitted with the top of the projector 21. After the fitting is completed, the user uses an external tool to rotate the mounting bolt 20 into the inner cavity of the limit block 19 and the support rod 4, fixes the support rod 4, and limits the projector 21 to prevent the projector 21 from falling and being damaged by external impact, thereby achieving the protection function. The user starts the cylinder 9 to work, drives the cross plate 8 to move downward through the cylinder 9, and drives the universal wheel 7 to move downward through the cross plate 8, so that the bottom of the universal wheel 7 fits with the ground, and the bottom of the bottom plate 11 is separated from the ground, thereby achieving the movement function. The projector 21 can be moved to the desired projection position without the need for manual carrying by the user, which saves time and effort. The bearing 12 is provided to reduce the wear of the threaded rod 2 during rotation and operation, and the loss of the threaded rod 2 during rotation and operation, thereby greatly improving the service life of the threaded rod 2.

[0037] The working principle of the utility model is as follows: before the projection work is needed, the user places the projector 21 on the top of the connecting plate 5. After the placement is completed, the user picks up the support rod 4 and passes the support rod 4 through the top of the connecting plate 5, so that the bottom of the support rod 4 is located below the connecting plate 5 and on one side of the limit block 19, and the inner surface of the limit plate 3 is fitted with the top of the projector 21. After the fitting is completed, the user uses an external tool to rotate the mounting bolt 20 into the inner cavity of the limit block 19 and the support rod 4, fixes the support rod 4, and limits the projector 21 to prevent the projector 21 from falling due to external impact. After the fixing is completed, the user starts the cylinder 9 to work, drives the cross plate 8 to move downward through the cylinder 9, and drives the universal wheel 7 to move downward through the cross plate 8. The projector 21 is moved upward by the connecting plate 5 and the connecting plate 5 moves upward, and the projector 21 stops moving when the user reaches the optimal viewing height, thereby achieving the height adjustment function. Similarly, the projector 21 can be moved downward by the driving motor 18 to rotate the threaded rod 2 in the counterclockwise direction.
