A liftable business training conference screen bracket

Abstract

This application discloses a liftable business training conference screen bracket, relating to the field of display screens. It includes a base, chassis, display screen, lifting assembly, and rotating assembly. The height of the display screen is adjusted through the cooperation of a motor, threaded rod, and threaded sleeve. After adjustment to a specified height, a locking plate engages with a limiting slot by rotating it. Further adjustment of the threaded sleeve lowers the locking plate until it engages with a groove at the bottom of the limiting slot, ultimately locking the display screen height for ease of use. Rotating the rotating gear on the outer surface of the connecting shaft drives the fixed gear ring to rotate, thereby adjusting the screen's deflection angle. Pushing the sliding rod and using a compression spring to engage the insert rod on the lower surface of the pressure plate with the insertion hole locks the rotating gear on the outer surface of the sliding rod with the fixed gear ring. A limiting block further locks the fixed gear ring by driving the rotating gear on the outer surface of the sliding rod, facilitating adjustment and locking of the deflection angle.

Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a liftable business training conference screen bracket. Background Technology

[0002] A business training conference screen is a display device specifically designed for internal training, meetings, and presentations within an enterprise or organization. It typically features high resolution, a large screen size, and excellent interactive functions, supporting the display of various media content such as videos, images, and documents. The design of business training conference screens aims to improve the efficiency of training and meetings, enhance the interactive experience of participants, and promote the effective transfer of knowledge and information.

[0003] Existing business training conference screens are installed on the ground in designated locations using brackets. The installation location of the conference screen usually needs to be arranged according to the spatial layout of the conference room to ensure that the orientation of the conference screen can ensure that most people in the conference room can view the content on the conference screen normally.

[0004] When setting up and installing existing conference screens, they are usually positioned at a certain angle in one corner of the conference room so that users in all positions in the conference room can view the screen normally. However, when conducting business training, it is usually necessary to rearrange the space in the conference room. The existing screens cannot be quickly oriented, so the entire screen has to be moved. This makes it impossible to adjust the orientation according to the rearranged seating, which is quite inconvenient to use. Utility Model Content

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Example 1

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This is the first embodiment of the present utility model. This embodiment provides a lifting business training conference screen bracket, including a base 1, a housing 2 fixedly installed on the upper surface of the base 1, a display screen 3 provided on one side of the housing 2, and a lifting component 4 provided inside the housing 2.

[0034] The lifting assembly 4 includes a threaded rod 404 movably connected inside the housing 2. A threaded sleeve 405 is engaged with the outer surface of the threaded rod 404. Support plates 412 are provided on both sides of the threaded sleeve 405. A movable cylinder 410 is provided above the support plate 412. A support spring 409 is fixedly installed between the movable cylinder 410 and the support plate 412. Two locking plates 406 are provided on the outer surface of the movable cylinder 410. A connecting arm 411 is provided between the movable cylinder 410 and the display screen 3. The two connecting arms 411 are hinged at the ends near the display screen 3 by a pin. The display screen 3 is hinged to the hinged parts of the two connecting arms 411 by a hinge seat.

[0035] Specifically, a motor 401 is fixedly connected inside the housing 2. The output end of the motor 401 is fixedly connected to the bottom end of the threaded rod 404. Two partitions 403 are fixedly connected inside the housing 2. The partitions 403 have rectangular openings that cooperate with the connecting plate 408. By setting the partitions 403, the threaded rod 404 on the inner wall of the housing 2 is closed, reducing the influence of the threaded rod 404 on the external environment. The rectangular openings on the outer surface of the partitions 403 facilitate the lifting and lowering of the connecting plate 408. The outer surface of the housing 2 also has rectangular slots for the lifting and lowering of the connecting arm 411.

[0036] Specifically, two limiting posts 402 are fixedly connected inside the chassis 2. The movable cylinder 410 and the support plate 412 are both sleeved on the outer surface of the limiting posts 402. The outer surface of the limiting posts 402 is provided with a limiting groove. The inner side of the movable cylinder 410 is provided with a limiting protrusion that cooperates with the limiting groove. By setting the limiting posts 402, the lifting and lowering of the movable cylinder 410 and the support plate 412 are limited. By the cooperation of the limiting groove and the limiting protrusion on the outer surface of the limiting posts 402, the movable cylinder 410 is limited and cannot rotate. In addition, the limiting posts 402 on both sides cooperate with the two support plates 412 respectively, so that the threaded sleeve 405 is limited and cannot rotate by the connecting plate 408.

[0037] Specifically, the outer surface of the movable cylinder 410 has an annular groove, and an arc-shaped groove connects the two annular grooves. Two connecting rods 407 are fixedly connected between the two locking plates 406 on the outer surface of the movable cylinder 410. The connecting rods 407 are movably disposed in the arc-shaped groove. The outer surface of the housing 2 has a limiting slot that mates with the locking plate 406. The bottom of the inner cavity of the limiting slot on the outer surface of the housing 2 has a groove that mates with the locking plate 406. The outer surface of the housing 2 has a rectangular opening that communicates with the limiting slot. The width of the annular groove matches the locking plate 406. The locking plate 406 is inserted into the annular groove and fixedly connected to the outer surface of the connecting rod 407. When the locking plate 406 is rotated, the connecting rod 407 slides in the arc-shaped groove, thereby moving the locking plate 406 in the annular groove. The stroke length of the annular groove is sufficient for the locking plate 406 to rotate from inside the limiting slot to inside the rectangular opening.

[0038] Furthermore, the height of the threaded sleeve 405 is adjusted by the threaded rod 404 driven by the motor 401, thereby adjusting the height of the movable cylinder 410. Then, the height of the display screen 3 is adjusted by the connecting arm 411. After adjusting to a suitable height, the locking plate 406 is manually rotated, so that the locking plate 406 rotates from the rectangular opening on the outer surface of the housing 2 into the limit slot. Then, the threaded sleeve 405 is moved down a small distance by the motor 401, thereby driving the locking plate 406 to insert into the groove on the inner wall of the limit slot, thereby locking the locking plate 406 and preventing it from rotating outward. Then, the threaded sleeve 405 is moved down a small distance, thereby driving the support spring 409 to extend, thereby increasing the pressure of the locking plate 406 pressing the groove, ensuring the stability of the display screen 3. Through the setting of the support spring 409 and the locking plate 406, the locking plate 406 is limited to be located inside the groove, thereby locking the height of the display screen 3.

[0039] Example 2

[0040] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, and the connecting arm 411 is provided with a rotating component 5 inside.

[0041] The rotating assembly 5 includes a fixed gear ring 501 fixedly installed on the side of the display screen 3 near the chassis 2. Both connecting arms 411 are provided with rotating gears 502. One of the rotating gears 502 is fixedly connected to a connecting shaft 503, which is movably connected to the inside of the connecting arm 411. The other rotating gear 502 is fixedly connected to a sliding rod 508, and two limit blocks 504 are fixedly connected to the outer surface of the sliding rod 508.

[0042] Specifically, a fixing block 507 is fixedly connected to the top of the sliding rod 508, a pressure plate 505 is fixedly installed on the top outer surface of the sliding rod 508, a compression spring 506 is provided between the pressure plate 505 and the fixing block 507, an insert rod 509 is fixedly installed on the lower surface of the pressure plate 505, an insertion hole that mates with the insert rod 509 is opened on the upper surface of the connecting arm 411, and a sliding groove that mates with the sliding rod 508 is opened on the upper surface of the connecting arm 411. The pressure plate 505 is pressed down by the compression spring 506, thereby driving the insert rod 509 to mate with the insertion hole, thereby locking the sliding of the sliding rod 508.

[0043] Specifically, the connecting arm 411 has a rectangular through groove inside that mates with the rotating gear 502. The inner wall of the rectangular through groove inside the connecting arm 411 near the display screen 3 has an arc-shaped surface that mates with the fixed gear ring 501. The inner wall of the rectangular through groove inside the connecting arm 411, which contains the sliding rod 508, has a limiting groove that mates with the limiting block 504. The top of the limiting groove is connected to the groove on the upper surface of the connecting arm 411, thus facilitating the sliding of the sliding rod 508 while limiting the rotation of the sliding rod 508 and the rotating gear 502 on the outer surface of the sliding rod 508. The fixed gear ring 501 is connected to the rectangular through groove inside the two connecting arms 411 in sequence. Through the engagement of the arc-shaped surface of the inner wall of the rectangular through groove inside the connecting arm 411 with the fixed gear ring 501, the fixed gear ring 501 is limited to rotate stably, preventing the fixed gear ring 501 from deviating.

[0044] Furthermore, by rotating the gear 502, the fixed gear ring 501 is driven to rotate, thereby causing the display screen 3 to rotate in a circle around the hinge of the two connecting arms 411. After rotating to a predetermined angle, the pressure plate 505 is lifted, thereby causing the insertion rod 509 to separate from the insertion hole, thereby pushing the sliding rod 508. This causes the rotating gear 502 on the outer surface of the sliding rod 508 to engage with the gear ring. Through the engagement of the limiting block 504 with the limiting groove in the inner cavity of the rectangular through groove inside the connecting arm 411, the rotating gear 502 on the outer surface of the limiting sliding rod 508 is prevented from rotating, thereby limiting and locking the fixed gear ring 501.

[0045] Working principle: When adjusting the conference screen used for business training, start motor 401. Motor 401 drives the rotation of threaded rod 404, which in turn moves threaded sleeve 405. Threaded sleeve 405, through connecting plate 408, moves support plate 412, causing support plate 412 to descend. Support plate 412 then moves movable cylinder 410 downward, causing locking plate 406 to disengage from the groove at the bottom of the limiting slot on the outer surface of chassis 2. Then, by moving locking plate 406, connecting rod 407 moves within the annular groove on the outer surface of movable cylinder 410, thereby rotating locking plate 406. At the rectangular opening on the outer surface of chassis 2, adjust the height of the threaded sleeve 405 as needed to adjust the height of the movable cylinder 410. Then, adjust the height of the display screen 3 via the connecting arm 411. After adjusting to the appropriate height, manually rotate the locking plate 406 into the slot. Then, control the threaded sleeve 405 to move down a small distance via the motor 401, thereby driving the locking plate 406 to insert into the groove on the inner wall of the limiting slot, thus locking the locking plate 406 and preventing it from rotating outward. Then, continue to control the threaded sleeve 405 to move down a small distance. This causes the support spring 409 to extend, thereby increasing the pressure of the movable cylinder 410 pressing the locking plate 406 into the groove, ensuring the stability of the display screen 3. When the angle needs to be adjusted, the connecting shaft 503 is rotated, which in turn drives the rotating gear 502 on the outer surface of the connecting shaft 503 to rotate. This rotating gear 502 drives the fixed gear ring 501 to rotate, thereby causing the display screen 3 to rotate in a circle around the hinge joint of the two connecting arms 411. After rotating to the set angle, the pressure plate 505 is lifted, which causes the insertion rod 509 to separate from the insertion hole, thereby pushing the sliding rod 508 and causing the outer surface of the sliding rod 508 to rotate. The rotating gear 502 engages with the gear ring, and through the engagement of the limiting block 504 with the limiting slide groove in the inner cavity of the rectangular through groove of the connecting arm 411, the rotating gear 502 on the outer surface of the limiting sliding rod 508 is prevented from rotating, thereby limiting and fixing the gear ring 501 and locking it. Then, the pressure plate 505 is released, and under the action of the compression spring 506, the pressure plate 505 is driven to press down, thereby driving the insertion rod 509 to engage with the insertion hole and locking it. This prevents the rotating gear 502 on the outer surface of the sliding rod 508 from moving and separating from the fixed gear ring 501, and finally completes the adjustment of the height and deflection angle of the display screen 3.
