Description

Technical Field

[0001] The present invention relates to the technical field of smart blackboard installation, and in particular to an installation and adjustment device for a smart blackboard all-in-one machine. Background Art

[0002] Smart blackboard all-in-one machines are usually installed on brackets, which generally have adjustment functions. The design of these brackets needs to combine the principles of mechanical engineering to ensure stability and durability during the adjustment process; different courses and teaching contents may require different display angles and heights. Through the adjustment device, the smart blackboard all-in-one machine can be easily adjusted to the most suitable angle and height to meet diverse teaching needs; modern classroom space is often limited, and the design of the smart blackboard all-in-one machine mounting bracket needs to consider how to provide maximum functionality without taking up too much space, and adjust the height and angle according to actual space requirements to enhance the flexibility of the equipment and space utilization.

[0003] When installing existing smart blackboard all-in-ones, they are usually fixed by bolts and clamping structures, resulting in low installation efficiency. When the smart blackboard needs to be replaced, it is difficult to quickly dismantle it, and the process is long, time-consuming and labor-intensive. In addition, the smart blackboard is generally fixed in a certain position for a long time. When the smart blackboard needs to be moved to other areas for display, the moving wheels at the bottom of the smart blackboard's mounting frame are almost all fixed designs. When moving to the appropriate position, fixed support is required to ensure sufficient stability. The moving wheels are in contact with the ground and are easily affected by external forces, causing rolling, resulting in insufficient stability and lack of support. In order to adjust the tilt angle of the smart blackboard, a rocker is generally provided in conjunction with a rotating shaft, a fixed arm and other structures to achieve this. However, since most of them do not have a self-locking structure, there is a risk of shaking and flipping after the angle is adjusted, and the safety is relatively low. Summary of the invention

[0038] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0039] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5 As shown, a smart blackboard integrated machine installation and adjustment device includes a base 1, a support frame 2 is installed on the top of the base 1, a telescopic frame 21 is slidably provided in the support frame 2, a mounting plate 22 is installed on the telescopic frame 21, and a lifting wheel support mechanism 3 is provided at the four corners of the bottom of the base 1;

[0040] The lifting wheel support mechanism 3 includes a support seat 31, a moving wheel 32 and a moving wheel height adjustment mechanism 33. A toothed disc 6 is rotatably provided on the upper part of the telescopic frame 21. A connecting tooth 61 is provided on the rear half of the circumferential outer wall of the toothed disc 6. A connecting disc 62 fixedly connected to the mounting plate 22 is extended forward on the front side. An inclination adjustment mechanism 7 with a self-locking function for driving the toothed disc 6 to rotate is provided in the telescopic frame 21. A pair of arc-shaped positioning plates 8 are provided on the front side of the mounting plate 22. A through groove is reserved in the middle of the arc-shaped positioning plate 8, and a quick-clamping mounting mechanism 9 fixed to the mounting plate 22 is provided on the outer side.

[0041] The working principle of the present invention is as follows: when it is necessary to install the smart blackboard all-in-one, the movable wheel 32 can be raised and lowered by the lifting movable wheel height adjustment mechanism 33, and cooperated with the support seat 31 to realize the movement and fixation of the base 1, thereby adjusting the position of the smart blackboard. When it is necessary to install the smart blackboard, the smart blackboard all-in-one is placed close to the mounting plate 22, so that the arc-shaped positioning plate 8 is docked with the clamping mechanism on the smart blackboard, and it can be quickly fixed to the mounting plate through the quick clamping mounting mechanism 9; when it is necessary to adjust the height of the smart blackboard, the lifting driving mechanism 5 is driven to work, so that the telescopic frame 21 moves up and down accordingly, thereby adjusting the height of the mounting plate 22 connected to the telescopic frame 21, and realizing the adjustment of the height of the smart blackboard; when it is necessary to adjust the inclination angle of the smart blackboard, the inclination adjustment mechanism 7 can drive the mounting plate 22 to rotate up and down on the telescopic frame 21, thereby adjusting the inclination angle of the smart blackboard.

[0042] Combined with Figure 1 , Attachment Figure 5 , Attachment Figure 6 and attached Figure 7 As shown, the moving wheel height adjustment mechanism 33 includes a moving wheel bracket 34 rotatably arranged on the support seat 31, an open slot is arranged on one side of the moving wheel bracket 34, and a pair of mounting side plates 35 are extended on the other side, a lifting slot 36 is reserved at the bottom of the mounting side plate 35, a connecting shaft 1 37 is slidably arranged in the lifting slot 36, a moving wheel 32 is rotatably arranged in the middle of the connecting shaft 1 37, and the ends of the moving wheel 32 pass through the lifting slot 36 and are located outside the mounting side plate 35;

[0043] A lever connecting plate 39 rotatably connected to the connecting shaft 1 37 is provided on the outer side of the mounting side plate 35, a rabbit ear plate 310 with a groove is provided on one side of the bottom of the lever connecting plate 39, a connecting shaft 2 311 is rotatably provided on the upper part of the mounting side plate 35, the end of the connecting shaft 2 311 passes through the mounting side plate 35 and is fixed with a rotating seat 312, the bottom of the rotating seat 312 is hinged to the lever connecting plate 39, and the other end is inclined upwardly provided with a pedal 313, a mounting hole 314 is provided on the top of the mounting side plate 35 near the moving wheel bracket 34, and a tension spring 38 is connected between the mounting hole 314 and the rabbit ear plate 310.

[0044] Embodiment 1: The support seat 31 includes a column 3101, in which a threaded rod support foot 3102 is slidably provided, and a horizontal adjustment knob 3103 is threadedly connected to the threaded rod support foot 3102, and the top of the horizontal adjustment knob 3103 is against the bottom of the column 3101. By rotating the horizontal adjustment knob 3103 on each support seat 31, the distance of the top of the threaded rod support foot 3102 entering the column 3101 can be adjusted, thereby adjusting the relative height of the four corners of the base 1, so that the smart blackboard as a whole remains in a horizontal state.

[0045] Embodiment 2: The support base 31 is designed with fixed legs, the height of the legs is not adjustable, the structure is relatively simple, and it is suitable for ground with good flatness. The smart blackboard is almost in a horizontal state and there is no need to adjust the levelness.

[0046] The working principle of the moving wheel height adjustment mechanism 33 for lifting and moving the moving wheel 32 is as follows: when the base 1 is fixed at a certain position and the smart blackboard needs to be moved, the pedal 313 is stepped on to drive the rotating seat 312 to rotate around the connecting shaft 2 311. Since the bottom of the rotating seat 312 is hinged to the top of the lever connecting plate 39, and the bottom of the lever connecting plate 39 is rotatably connected to the connecting shaft 1 37, the lever connecting plate 39 will first drive the connecting shaft 1 37 to move downward in the lifting groove 36, so that the moving wheel 32 moves downward accordingly. When the bottom of the moving wheel 32 is in contact with the ground, the rotating seat 312 will drive the top of the lever connecting plate 39 to rotate around the connecting shaft. 1 37 rotates until the lever connecting plate 39 is in a vertical state. During this process, the moving wheel 32 lifts the support seat 31, so that the threaded rod support foot 3102 is separated from the ground. The tension spring 38 stretches and extends during this process, giving the lever connecting plate 39 a tensile stress in the same direction of rotation to maintain structural stability. The lifting wheel support mechanism 3 at the four corners of the bottom surface of the base 1 is operated in turn to complete the lifting of the base 1. At this time, the smart blackboard can be easily moved by pushing it. When it is moved to the appropriate position and needs to be re-fixed, the pedal 313 is hooked upward with the foot, and the threaded rod support foot 3102 falls back to contact the ground to complete the support and fixation.

[0047] Combined with Figure 4 , Attachment Figure 8 As shown, the base 1 is composed of two upper and lower plates assembled and spliced ​​together, and a pair of movable grooves 4 are reserved thereon. A slider 401 is slidably arranged in the movable groove 4. The top of the slider 401 is hinged to the outer wall of the telescopic frame 21 on the same side through a hinge rod 402. A lifting drive mechanism 5 is arranged in the base 1 for driving the slider 401 to slide left and right.

[0048] Embodiment 1: The lifting drive mechanism 5 includes a threaded rod 51 rotatably set in the moving groove 4 and threadedly connected to the slider 401, and the other end of the threaded rod 51 is fixed with a bevel gear 52 rotatably set in the base 1. The middle part of the base 1 is provided with a rotating shaft 53 rotatably set perpendicular to the threaded rod 51, and the rear end of the rotating shaft 53 is fixed with a bevel gear 2 54 rotatably set in the base 1. The front end of the rotating shaft 53 extends out of the base 1 and is connected to a rotating handle 55, and the bevel gear 2 54 and the bevel gear 1 52 are meshed with each other.

[0049] The working principle of the lifting drive mechanism 5 driving the telescopic frame 21 to lift and lower is as follows: rotate the rotating handle 55, the rotating shaft 53 rotates accordingly and drives the bevel gear 2 54 to rotate, and the bevel gear 2 54 drives the bevel gears 1 52 on the left and right sides meshing therewith to rotate in the opposite direction, so that the threaded rods 51 in the movable grooves 4 on the left and right sides rotate in opposite directions, so that the sliders 401 threadedly connected with the threaded rods 51 move in opposite directions in the movable grooves 4 on the left and right sides, and the top of the slider 401 is hinged to the outer wall of the telescopic frame 21 on the same side through the hinge rod 402, which will drive the telescopic frame 21 to move up and down. In this process, the threaded rod 51 is threadedly connected to the slider 401. When the rotating handle 55 stops rotating, self-locking can be achieved, and the telescopic frame 21 stops moving accordingly, which is convenient and efficient.

[0050] Embodiment 2: The lifting drive mechanism 5 includes a pair of electric telescopic rods distributed on the left and right sides arranged in the base 1. The electric telescopic rods are close to each other and arranged back to back in the middle of the base 1. The telescopic shaft ends of the electric telescopic rods are fixedly connected to the slider 401, and the electric telescopic rods on the left and right sides are synchronously driven by a driver.

[0051] The working principle of the lifting drive mechanism 5 driving the telescopic frame 21 to lift and lower is as follows: the electric telescopic rod is driven to work, and the telescopic shaft end of the electric telescopic rod drives the slider 401 to move in the opposite direction in the moving groove 4. The top of the slider 401 is hinged to the outer wall of the telescopic frame 21 on the same side through the hinge rod 402, which will drive the telescopic frame 21 to move up and down. In this process, due to the support of the electric telescopic rod, the telescopic frame 21 moves with the working state of the electric telescopic rod, and can maintain a stable state when moving stably and being stationary.

[0052] Combined with Figure 4 , Attachment Fig. 9 , Attachment Fig.10 and attached Fig.11 As shown, the inclination adjustment mechanism 7 includes a limiting seat 71 arranged in the telescopic frame 21, a transmission rod 72 is slidably arranged in the limiting seat 71, a tooth groove 73 meshing with the connecting tooth 61 is arranged on the top of the transmission rod 72, a tooth groove 74 is arranged on the bottom, and a rotating rod 75 and a rotating rod 78 rotatably arranged in the telescopic frame 21 are arranged on the same side as the tooth groove 74, a transmission gear 76 meshing with the tooth groove 74 and a transmission gear 77 located on the front side of the transmission gear 76 are sleeved and fixed on the rotating rod 75, a matching gear 79 meshing with the transmission gear 77 is sleeved and fixed on the rotating rod 78, a rotating handle 710 is arranged at the front end passing through the telescopic frame 21, and an automatic clamping unit 711 is arranged in the telescopic frame 21;

[0053] The automatic locking unit 711 includes a ratchet 7111 which is sleeved and fixed on the rotating rod 78. A pawl 7112 which cooperates with the ratchet 7111 is rotatably provided on the upper side of the rotating rod 78. A pressing plate 7113 is provided on the other end of the pawl 7112 which passes through the telescopic frame 21. A spring 7114 fixed on the inner wall of the telescopic frame 21 is provided near the pawl 7112. The free end of the spring 7114 is in close contact with the pawl 7112.

[0054] The working principle of the inclination adjustment mechanism 7 for adjusting the inclination of the smart blackboard: when the smart blackboard needs to be tilted downward to adjust the inclination, the handle 2 710 is rotated clockwise to drive the rotating rod 2 78 to rotate, thereby driving the matching gear 79 to rotate, and the matching gear 79 drives the transmission gear 2 77 meshing therewith to rotate, thereby driving the rotating rod 1 75 together with the transmission gear 1 76 to rotate, and when the transmission gear 1 76 is meshed with the tooth groove 2 74, the transmission rod 72 moves upward accordingly, and when the tooth groove 1 73 is meshed with the connecting tooth 61, the transmission rod 72 drives the tooth plate 6 to rotate downward in the telescopic frame 21, so that the tooth plate 6 drives the mounting plate 22 to rotate downward through the connecting plate 62, thereby realizing the adjustment of the downward inclination angle of the smart blackboard; when the smart blackboard needs to be adjusted upward to adjust the inclination, the handle 2 710 is rotated counterclockwise, and the transmission rod 72 can be driven to move downward by the same principle, thereby driving the tooth plate 6 to rotate upward in the telescopic frame 21, and driving the mounting plate 22 to rotate upward to realize the adjustment of the upward inclination angle of the smart blackboard.

[0055] The working principle of the automatic locking unit 711 locking the inclination angle of the smart blackboard: when the handle 2 710 is rotated clockwise, the ratchet 7111 rotates clockwise with the rotating rod 2 78, and the pawl 7112 cooperates with the ratchet 7111 to slide freely. When the proper angle is adjusted, the handle 2 710 is stopped, and the ratchet 7111 stops rotating. At this time, the pawl 7112 cooperates with the spring spring 7114 to fix the ratchet 7111 to prevent the ratchet 7111 from rotating counterclockwise, thereby making the blackboard tilted. The smart blackboard is fixed at a certain angle and will not change; when the handle 2 is rotated counterclockwise, the pressing plate 7113 is pressed downward, driving the pawl 7112 to rotate around the sleeve, thereby compressing the clockwork spring 7114, so that the pawl 7112 is separated from the ratchet 7111. At this time, after adjusting to a suitable angle, release the pressing plate 7113, and the clockwork spring 7114 drives the pawl 7112 and the ratchet 7111 to cooperate and fix, so that the smart blackboard is fixed at a certain angle and will not change.

[0056] It should be noted that the hook on the ratchet 7111 is bent in the counterclockwise direction, and an oblique slot for the pressing plate 7113 to rotate is reserved on the telescopic frame 21. The free end of the spring 7114 is in contact with the outer wall of the ratchet 7112 in a contracted and tensioned state, and the clockwise direction of the spring 7114 is the contraction direction.

[0057] In addition, it is necessary to explain the role of the additional transmission gear 1 76 and transmission gear 2 77: when the ratchet 7111 is locked with the pawl 7112, it is to ensure that the transmission rod 72 will not move upward under the drive of the toothed disc 6. If a matching gear 79 is separately provided to mesh with the tooth groove 2 74, the upward movement of the transmission rod 72 will drive the matching gear 79 and the rotating rod 2 78 to rotate counterclockwise. Since the hook on the ratchet 7111 is bent in the counterclockwise direction, the ratchet 7111 and the pawl 7112 will rotate smoothly and will not be locked. Setting the transmission gear 2 77 between the transmission rod 72 and the matching gear 79 will change the rotation direction of the ratchet 7111, so that when the transmission rod 72 moves upward, the rotation direction of the ratchet 7111 is clockwise. At this time, the pawl 7112 can lock the ratchet 7111 to achieve self-locking.

[0060] The movable limiting unit includes a sliding rod 911 slidably arranged in the placement groove 910, and a slanted groove 913 inclined upward is reserved on the side of the sliding rod 911 facing the matching connecting rod 912, and the end of the matching connecting rod 912 is slidably connected to the slanted groove 913, and the bottom end of the sliding rod 911 is connected to the bottom of the placement groove 910 with a telescopic spring three 914, and the top is provided with a clamping block 915 that slidably cooperates with the conical seat 94; the connecting block 91 is close to the side of the arc-shaped positioning plate 8 and is reserved with a small notch that is slidably connected to the push-pull rod 93 and is connected to the telescopic groove 92, and when the conical seat 94 is fitted with the small notch, the end of the push-pull rod 93 passes through the arc-shaped positioning plate 8 and is located on its inner side, one side of the clamping block 915 is provided with a vertical section that fits with the vertical side of the conical seat 94, and the other side is provided with an inclined surface that slidably cooperates with the arc inclined surface of the conical seat 94.

[0061] The working principle of the quick-connect installation mechanism 9 is as follows: when the smart blackboard needs to be installed and fixed on the mounting plate 22, first dock the mounting frame of the smart blackboard with the arc-shaped positioning plate 8, and align the docking interface with the through groove on the arc-shaped positioning plate 8, then press down the pressing column head 97 to drive the sleeve 95 and the matching connecting rod 912 to move in the direction of the arc-shaped positioning plate 8. During this process, the matching connecting rod 912 cooperates with the inclined groove 913 on the slide bar 911 to slide, driving the slide bar 911 to move downward, and the telescopic spring three 914 is compressed, so that the card block 915 is separated from the conical seat 94. At the same time, during the movement of the sleeve 95, the telescopic spring one 96 is squeezed and compressed, so when the conical seat 94 is separated from the card block 915, the telescopic spring one 96 will drive the conical seat 94 together with the push-pull rod 93 to move in the direction of the arc-shaped positioning plate 8 until the conical seat 94 is in contact with the inner wall of the connecting block 91, and the end of the push-pull rod 93 passes through the arc-shaped positioning plate 8. The through groove on the smart blackboard is connected and fixed with the docking interface on the smart blackboard. At this time, the installation and fixation of the smart blackboard are completed. The pressing column head 97 is released, and under the action of the telescopic spring second 98, the sleeve 95 and the matching connecting rod 912 return to the initial position, and the slide bar 911 moves upward and resets under the action of the telescopic spring third 914; when the smart blackboard needs to be separated from the mounting plate 22, the lifting column head 99 is pulled outward to drive the conical seat 94 to move in the direction of the sleeve 95. During this process, the conical side surface on the conical seat 94 cooperates with the inclined surface on the block 915 to drive the slide bar 911 to move downward, and the telescopic spring third 914 is compressed and shortened. When the conical seat 94 is separated from the block 915, the telescopic spring third 914 drives the slide bar 911 to move upward, releases the lifting column head 99, and the block 915 cooperates with the conical seat 94 again, and the one-way limiting push-pull rod 93 moves in the direction of the arc-shaped positioning plate 8, completing the removal of the smart blackboard.

[0062] When the present invention is implemented in detail: when the smart blackboard all-in-one is installed, the mounting frame of the smart blackboard is docked with the arc-shaped positioning plate 8, and the docking interface is aligned with the through groove on the arc-shaped positioning plate 8, the pressing column head 97 is pressed down, and the smart blackboard is quickly installed on the mounting plate 22 through the quick-clamping mounting mechanism 9. When the smart blackboard needs to be moved to other areas, the pedal 313 is stepped on to drive the moving wheel 32 to fit the ground until the base 1 is propped up and the support seat 31 is separated from the ground. At this time, the smart blackboard can be easily moved by pushing it. When it is moved to a suitable position and needs to be re-fixed, the pedal 313 is hooked upward with the foot, and the support seat 31 falls down again and contacts the ground to complete the support and fixation; when the height of the smart blackboard needs to be adjusted, the telescopic frame 21 is driven to rise and fall through the lifting drive mechanism 5, thereby changing the height of the smart blackboard. When the up and down tilt angles of the smart blackboard need to be adjusted, the rotating handle 2 710 is rotated to drive the gear plate 6 to rotate on the telescopic frame 21, thereby changing the tilt angle of the smart blackboard. This device can quickly install and dismantle the smart blackboard, and can quickly adjust the height and tilt angle of the smart blackboard as needed. The smart blackboard can also be quickly moved to other areas and then fixed again as needed, which is convenient and efficient.

[0063] The present invention and its embodiments are described above, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and do not deviate from the purpose of the invention, they can creatively design a structure and embodiment similar to the technical solution, which should fall within the protection scope of the present invention.
