DETAILED DESCRIPTION

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a health education and publicity display device, including a support base 1. A caster wheel 2 is provided on the lower surface of the support base 1. The caster wheel 2 is existing technology and can be implemented by those skilled in the art; therefore, it will not be described in detail in this case. A locking pedal is provided on the caster wheel 2; pressing the locking pedal downwards locks the caster wheel 2. Three sets of caster wheels 2 are arranged in a circular array with the center of the support base 1 as the origin, ensuring the stability of the device. A support rod 3 is fixedly connected to the upper surface of the support base 1, and a bracket 4 is fixedly connected to the upper surface of the support rod 3. The centers of the support base 1, support rod 3, and bracket 4 are aligned longitudinally. An adjustment component is provided on the outer wall of the support rod 3, which can flexibly adjust the display angle of the screen 5 according to the observer's viewing height. A support component is provided on the upper surface of the support base 1 to maintain the stability of the device during use.

[0034] Reference Figure 1 - Figure 3 The adjustment assembly includes a motor 61, with a screw 62 fixedly connected to the output shaft of the motor 61. Both the motor 61 and the screw 62 are existing technologies, and can be implemented by those skilled in the art. Therefore, they will not be described in detail in this case. After the motor 61 starts, it drives the screw 62 to rotate. The output shaft of the motor 61 can rotate forward and backward. A moving block 63 is threadedly connected to the outer wall of the screw 62. When the screw 62 rotates, it drives the moving block 63 to move longitudinally. A connecting block 64 is fixedly connected to the outer wall of the moving block 63. One end of the connecting rod 65 is hinged to the left surface of the support rod 3, and the other end of the connecting rod 65 is hinged to the display screen 5. When the connecting block 64 moves longitudinally with the moving block 63, it will squeeze the connecting rod 65, causing it to rotate and change the tilt angle of the display screen 5. When playing health education videos, patients usually sit to watch. At this time, the top of the display screen 5 can be pushed out to tilt it, making it easier for patients to watch. A sleeve 66 is fixedly connected to the left surface of the support rod 3, and a slider 68 is slidably connected to the inner wall of the sleeve 66. A sliding rod 67 is fixedly connected to the left surface of the slider 68.

[0035] Reference Figure 1 , Figure 4The support assembly includes a connecting plate 71, which is L-shaped. A pedal 72 is fixedly connected to the lower surface of the connecting plate 71. The pedal 72 can be stepped on downwards. When the pedal 72 contacts the ground, it will press against the ground, increasing the contact area between the device and the ground and improving the stability of the device. A slot 701 is provided on the right surface of the connecting plate 71. A block 74 is elastically connected to the inner wall of the support base 1 through a compression spring 73. The slot 701 and the block 74 fit together.

[0036] Reference Figure 1 - Figure 3 The motor 61 is mounted on the upper surface of the bracket 4. The screw 62 passes through and is rotatably connected to the upper surface of the support rod 3 and the bracket 4. The moving block 63 is disc-shaped in the middle and cross-shaped around the perimeter. The moving block 63 passes through and is slidably connected to the outer wall of the support rod 3. When the moving block 63 moves longitudinally, it can remain stable. The slide rod 67 passes through and is slidably connected to the left surface of the sleeve 66. The left end of the slide rod 67 is hinged to the right surface of the display screen 5. The slide rod 67 can provide support for the display screen 5. The connecting rod 65, sleeve 66, slide rod 67, slider 68 and display screen 5 are all provided in three sets, arranged in a circular array with the center of the support rod 3 as the origin, so that people can easily observe the health education video from multiple directions.

[0037] Reference Figure 1 , Figure 4 The left end of the connecting plate 71 is hinged to the upper surface of the support base 1. The locking block 74 is inserted into the inner wall of the slot 701, which can limit the connection plate 71 and the pedal 72 to ensure the stability of the pedal 72. The right end of the upper surface of the locking block 74 is set as an arc surface. When the arc surface is compressed, the locking block 74 will move to the left. One end of the compression spring 73 is fixedly connected to the left surface of the locking block 74, and the other end of the compression spring 73 is fixedly connected to the inner wall of the left side of the support base 1. The locking block 74 passes through and slides on the right surface of the support base 1. When the locking block 74 moves to the left, it will gradually retract into the interior of the support base 1, release the obstruction, and compress the compression spring 73 to generate a reaction force.

[0038] Working principle: First, push the device to the location of use. When pushing the device, the casters 2 can rotate flexibly, making it easy to move the device to the appropriate position. After reaching the designated position, step down on the locking pedal on the casters 2 to lock them.

[0039] Then the pedal 72 is pressed down, the connecting plate 71 is rotated, the pedal 72 is gradually close to the ground, and when the connecting plate 71 rotates, the arc surface of the clamping block 74 is extruded, so that it moves to the left and is retracted into the support base 1 to release the block, when the clamping block 74 moves to the left, the compression spring 73 is extruded to generate a reaction force, when the pedal 72 and the ground are attached, the clamping block 74 is aligned with the clamping groove 701, at this time the compression spring 73 pushes the clamping block 74 out of the clamping groove 701, and the connecting plate 71 and the pedal 72 are limited, to ensure the stability of the pedal 72, then the plurality of pedals 72 are pressed in turn, the contact area between the device and the ground is increased, and the stability of the device is enhanced.

[0040] Then according to the needs of the crowd, the inclination angle of the display screen 5 displaying the health education propaganda video is adjusted, and when adjusting, the motor 61 is started. The output shaft of the motor 61 drives the screw rod 62 to rotate, and the rotation of the screw rod 62 drives the moving block 63 and the connecting block 64 to move longitudinally, because the left surface of the connecting block 64 is hinged to one end of the connecting rod 65, and the other end of the connecting rod 65 is hinged to the display screen 5, so the longitudinally moving connecting block 64 will extrude the connecting rod 65 to make it rotate, thereby changing the inclination angle of the display screen 5.

[0041] When playing health education videos, patients often watch while sitting, and this adjustment mode can make the top end of the display screen 5 be tilted out, so that patients can watch conveniently without having to look up, thereby improving the viewing comfort.

[0042] When the device needs to be moved again, the clamping block 74 is pressed into the support base 1 to release the limiting of the connecting plate 71 and the pedal 72, then the pedal 72 is lifted, and finally the locking pedal is lifted to release the locking of the universal wheel 2, so that the device can be moved.

[0043] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or make equivalent replacement for some technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
