DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-Figure 3The utility model provides an embodiment: a BIM building model display device, including a base 1, a universal wheel is arranged at the bottom of the base 1, and the device can be pushed to move to the place to be displayed by the universal wheel. A groove 5 is opened on the top outer wall of the base 1, and a plurality of groups of grooves 5 are arranged. The circumference of equal angles are opened on the top of the base 1. A rotating mechanism 4 is arranged on the top outer wall of the base 1. The display screen 6 can be rotated by the rotating mechanism 4 and adjusted according to the direction of display required. A fixing mechanism 2 is arranged on the top of the rotating mechanism 4. The display screens 6 of different sizes can be fixed conveniently and quickly by the fixing mechanism 2, which has higher adaptability and is easy to operate.

[0034] Reference Figure 2-Figure 4 The fixing mechanism 2 includes a connecting block 201, which is fixed above the turntable 401. When the turntable 401 rotates, the connecting block 201 rotates synchronously, which can drive the display screen 6 to rotate. The top outer wall of the connecting block 201 is fixedly connected with a vertical plate 202. The display screen 6 can be placed at the front end of the connecting block 201 for fixing. The inner wall of the vertical plate 202 is elastically connected with a cover plate 204 through a telescopic spring 203. The cover plate 204 can move up and down at the front end of the vertical plate 202 and contact with the top of the display screen 6 to fix the display screen 6. One end of the telescopic spring 203 is fixedly connected to the outer wall of the cover plate 204. When not affected by external force, the cover plate 204 is below the vertical plate 202. When the cover plate 204 is pulled upward, the telescopic spring 203 is stretched by force, and the display screen 6 can be placed in the connecting block 201.

[0035] Reference Figure 2-Figure 4 The other end of the telescopic spring 203 is fixedly connected to the inner wall of the vertical plate 202, and the cover plate 204 is slidably connected to the inner wall of the vertical plate 202. After placement, the cover plate 204 moves downward due to the elastic force of the telescopic spring 203, and the top of the display screen 6 can be fixed. The inner wall of the connecting block 201 is slidably connected with a fixing plate 206. When the fixing plate 206 moves, it is guided by the inner wall of the connecting block 201 to maintain a horizontal movement state. The outer wall of the fixing plate 206 is hinged by the connecting rod 205 There is a pull rod 207, and two groups of fixed plates 206 and connecting rods 205 are provided. The two groups of connecting rods 205 are hinged to the pull rod 207, one end of the connecting rod 205 is hinged to the outer wall of the pull rod 207, and the other end of the connecting rod 205 is hinged to the outer wall of the fixed plate 206. When the pull rod 207 is moved forward and backward, the fixed plate 206 can be driven to move by flipping the connecting rod 205. Since the fixed plate 206 is slidably connected to the inner wall of the connecting block 201, it keeps moving horizontally to the middle or both sides at the same time.

[0036] Reference Figure 2-Figure 4A slot 208 is provided on the outer wall at the top end of the pull rod 207. There are multiple groups of slots 208, which can move the pull rod 207 to multiple positions and limit it in one direction. A limit assembly 3 is provided on the outer wall of the connecting block 201. The position of the pull rod 207 can be fixed by the limit assembly 3. A display screen 6 is detachably installed on the inner wall of the connecting block 201. The display screen 6 is a device used for displaying BIM building models. It is a prior art and can be placed on the device for display.

[0037] Reference Figure 4 The limit assembly 3 includes a fixed block A301, which is fixedly connected to the outer wall of the connecting block 201. The inner wall of the fixed block A301 is elastically connected to the wedge block 303 through a spring A302. The outer wall of the wedge block 303 is provided with a protrusion, which penetrates through one side of the outer wall of the fixed block A301. The wedge block 303 can be driven to move by moving the protrusion. One end of the spring A302 is fixedly connected to the outer wall of the wedge block 303, and the other end of the spring A302 is fixedly connected to the inner wall of the fixed block A301. When not affected by external force, the wedge block 303 keeps in contact with the inner wall of the slot 208, so that The pull rod 207 cannot move inward, so that the two groups of fixed plates 206 remain in a state of being unable to move to the sides, ensuring the clamping and fixing effect of the display screen 6. The outer wall of the wedge block 303 is slidably connected to the inner wall of the fixed block A301. When the pull rod 207 is pulled, the arc surface of the wedge block 303 is squeezed by the inner wall of the slot 208 and moves upward along the inner wall of the fixed block A301, so that the pull rod 207 can be pulled out, and the wedge block 303 is engaged with the slot 208. By moving the protrusion to disengage the wedge block 303 from the slot 208, the pull rod 207 can be moved inward, driving the two groups of fixed plates 206 to move to the sides.

[0038] Reference Figure 5 The rotating mechanism 4 includes a rotating disk 401, which is rotatably connected to the top outer wall of the base 1, and is fixedly connected to the connecting block 201. The display screen 6 can be driven to rotate by rotating the rotating disk 401. The outer wall of the rotating disk 401 is fixedly connected to a fixed block B402. The inner wall of the fixed block B402 is elastically connected to a clamping block 404 through a spring B403. The clamping block 404 penetrates the upper and lower outer walls of the fixed block B402, and the clamping block 404 can be pulled upward to release the limit of the rotating disk 401. The spring B403 One end of spring B403 is fixedly connected to the outer wall of block 404, and the other end of spring B403 is fixedly connected to the inner wall of fixed block B402. After the limit of turntable 401 is released, turntable 401 can be rotated, and the elastic force of spring B403 can drive block 404 to pop up downward for limiting. The outer wall of block 404 is slidably connected to the inner wall of fixed block B402, and block 404 is engaged with groove 5. The direction of display screen 6 can be rotated and adjusted conveniently and quickly through rotating mechanism 4, which is more convenient for visitors to use.

[0039] Working principle: When placing the display screen 6, the operator can first move the cover plate 204 upwards, and the telescopic spring 203 is stretched. Then the display screen 6 is placed on the inner wall of the connecting block 201. The cover plate 204 is moved downward by the elastic force of the telescopic spring 203. The cover plate 204 contacts the top of the display screen 6, and the top and bottom of the display screen 6 can be fixed. Display screens 6 of different heights can be fixed by the cover plate 204.

[0040] Then the operator can pull the pull rod 207 outward, and drive the fixed plate 206 to move toward the middle at the same time through the two sets of connecting rods 205. At this time, the inner wall of the slot 208 squeezes the arc surface of the wedge block 303, so that the wedge block 303 moves upward along the inner wall of the fixed block A301. When the fixed plate 206 moves to contact the outer walls of both sides of the display screen 6, the spring A302 drives the wedge block 303 to move downward due to the elastic force, and the straight surface of the wedge block 303 contacts the inner wall of the slot 208, making it impossible for the pull rod 207 to move inward. Since the fixed plate 206 contacts the side wall of the display screen 6, the pull rod 207 can be limited to keep the two sets of fixed plates 206 clamping and fixing the display screen 6.

[0041] When it is necessary to clamp and fix display screens 6 of different widths, the operator can move the protrusion set on the outer wall of the wedge block 303 to disengage the wedge block 303 from the slot 208, and then move the pull rod 207 inward. The connecting rod 205 drives the two sets of fixing plates 206 to move toward the middle, so that the smaller display screen 6 can be clamped. The adjustment process is simpler and more adaptable.

[0042] When it is necessary to adjust the direction of the display screen 6, the block 404 can be pulled upward to disengage from the groove 5, and the limit of the turntable 401 can be released, so that the turntable 401 can be rotated, driving the fixing mechanism 2 and the display screen 6 to rotate synchronously. When it is rotated to a suitable angle, the block 404 is released, and due to the elastic force of the spring B403, the block 404 pops up downward and engages with the groove 5, so that the turntable 401 can be limited, thereby fixing the direction of the display screen 6. It is more convenient and quick, and visitors can operate it by themselves.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
