Technical Field

[0001] This utility model relates to the field of educational display technology, and in particular to an inspirational display device. Background Technology

[0002] Inspirational display installations refer to various display equipment and tools used for publicity and education purposes. These installations are usually used in places such as schools, museums, exhibition halls, and community centers to display publicity content, educational materials, exhibits, etc., in order to attract the attention of the audience, convey information, and improve the public's awareness and understanding of a certain theme or issue.

[0003] Existing inspirational display devices mainly rely on manual pushing to move them to the designated display location. Once in place, the device plays various promotional content through its built-in display screen to achieve information dissemination and display effects.

[0004] However, display devices often need to be displayed under different terrain conditions, but existing display devices are not equipped with effective fixing devices. This means that during the display process, the device may be displaced due to external factors (such as minor collisions, wind effects, etc.), which not only affects the normal display of the promotional content, but may also damage the device itself, and even pose a safety hazard to people around. Utility Model Content

[0005] The lack of effective fixing devices for existing inspirational display devices poses a technical problem, as the devices may shift due to external factors during the display process, thus affecting the normal display of promotional content.

[0006] The technical solution of this utility model is as follows: an inspirational display device, including a base; it also includes a fixing block and a lifting assembly; a universal wheel is fixedly connected to the lower end of the base, a lifting assembly is provided on one side of the base, a fixing block is fixedly connected to one side of the base, a first threaded rod is threadedly connected to the inner side of the fixing block, a knob is fixedly connected to the upper end of the first threaded rod, an installation block is provided on the outer side of the first threaded rod, a fixing pin is provided on the inner side of the installation block and the first threaded rod, a fixing suction cup for adsorption and fixation is fixedly connected to the lower end of the installation block, a spring is provided on the inner side of the fixing pin, a limit bead is provided on one side of the spring, and a pull ring is provided on the inner side of the fixing pin.

[0007] Preferably, the lower end of the mounting block is fixedly connected to a auger bit for replacing the fixed suction cup.

[0008] Preferably, two sets of fixing blocks are provided, and the two sets of fixing blocks are symmetrically arranged on both sides of the base.

[0009] Preferably, the fixing pin has a groove, and the limiting bead is slidably connected inside the fixing pin through the groove.

[0010] Preferably, the lifting assembly includes a guide column, a guide column is fixedly connected to the upper end of the base, a drive motor is fixedly connected to the inner side of the base, a second threaded rod is fixedly connected to the output end of the drive motor, a support column is threadedly connected to the outer side of the second threaded rod, an electronic display screen is fixedly connected to the upper end of the support column, a canopy is fixedly connected to the upper end of the electronic display screen, and a transmission assembly is provided on the outer side of the second threaded rod.

[0013] The beneficial effects of this utility model are as follows: Compared with traditional heuristic display devices that lack effective fixing devices, which may cause the device to shift due to external factors during the display process, thus affecting the normal display of the promotional content, this device uses replaceable fixing suction cups and auger drill bits. The fixing suction cups are used on smooth surfaces, while the auger drill bits are used on soil surfaces. By rotating a knob, the knob drives the first threaded rod to rotate, which in turn drives the mounting block to rotate. The mounting block then drives the fixing suction cups or auger drill bits to rotate, allowing the fixing suction cups to adhere to the smooth surface or the auger drill bits to rotate into the soil, thereby fixing the device. After fixing, the device is prevented from shifting due to external factors, ensuring the normal display of the promotional content. Attached Figure Description

A limiting bead 308 is provided on one side of the spring 307, and a pull ring 309 is provided on the inner side of the fixing pin 306. A spiral drill bit 310 for replacing the fixing suction cup 305 is fixedly connected to the lower end of the mounting block 304. The fixing suction cup 305 is used to adhere to a smooth surface, thus fixing the device. The spiral drill bit 310 is used to rotate and enter the soil, thus fixing the device. Two sets of fixing blocks 301 are provided, symmetrically arranged on both sides of the base 1. A groove is provided on the fixing pin 306, and the limiting bead 308 is slidably connected to the inside of the fixing pin 306 through the groove. A groove is provided on the upper part, allowing the limiting bead 308 to slide inside the fixing pin 306, thus guiding and limiting the limiting bead 308. The universal wheel 2 is rolled by the pushing device, thereby moving the device. After moving to the designated position, the pull ring 309 is pulled, causing the fixing pin 306 to move. The limiting bead 308 is squeezed and slides into the inside of the fixing pin 306, thus pulling out the fixing pin 306. Then, the fixing suction cup 305 and the auger drill bit 310 are replaced as needed. The fixing suction cup 305 is used on smooth surfaces, and the auger drill bit 310 is used on soil surfaces. The fixing pin 306 is then placed on the outside of the first threaded rod 302 by fitting the mounting block 304 over it. Insert the device into the mounting block 304 and the first threaded rod 302. The limiting bead 308 is squeezed and slides into the inside of the fixing pin 306. The limiting bead 308 squeezes the spring 307. After the fixing pin 306 is installed in place, the spring 307 drives the limiting bead 308 to slide, thereby preventing the fixing pin 306 from falling off. By rotating the knob 303, the knob 303 drives the first threaded rod 302 to rotate. The first threaded rod 302 drives the mounting block 304 to rotate. The mounting block 304 drives the fixing suction cup 305 or the auger drill bit 310 to rotate, so that the fixing suction cup 305 is attached to the smooth ground, or the auger drill bit 310 is rotated into the soil, thereby fixing the device. After fixing is completed.

[0018] Please see Figure 5In this embodiment, the lifting assembly includes a guide column 401. The guide column 401 is fixedly connected to the upper end of the base 1. A drive motor 402 is fixedly connected to the inner side of the base 1. A second threaded rod 403 is fixedly connected to the output end of the drive motor 402. A support column 407 is threadedly connected to the outer side of the second threaded rod 403. An electronic display screen 408 is fixedly connected to the upper end of the support column 407. A canopy 409 is fixedly connected to the upper end of the electronic display screen 408. A transmission assembly is provided on the outer side of the second threaded rod 403. Two sets of second threaded rods 403 are provided, and the two sets of second threaded rods 403 are symmetrically rotatably connected to the inner side of the base 1. A first sprocket 404 is fixedly connected to the outer side of one set of second threaded rods 403, and the other set of second threaded rods 403... A second sprocket 406 is fixedly connected to the outer side. A chain 405 is provided on the outer side of the second sprocket 406. The first sprocket 404 and the second sprocket 406 are driven by the chain 405. By rotating the second threaded rod 403, the second threaded rod 403 drives the first sprocket 404 to rotate. The first sprocket 404 drives the chain 405 to rotate. The chain 405 drives the second sprocket 406 to rotate, thereby driving the two sets of second threaded rods 403 to rotate simultaneously. A second groove is opened on the guide post 401. The support post 407 is slidably connected to the inside of the guide post 401 through the second groove. The second groove on the guide post 401 allows the support post 407 to be slidably connected to the inside of the guide post 401, thereby providing a guiding and limiting effect for the support post 407.

[0019] During operation, the universal wheel 2 is rolled by pushing the device, thereby moving the device. After moving to the designated position, the pull ring 309 is pulled, which moves the fixing pin 306. The limiting bead 308 is squeezed and slides into the inside of the fixing pin 306, thereby pulling out the fixing pin 306. Then, the fixing suction cup 305 and the auger drill bit 310 are replaced as needed. The fixing suction cup 305 is used on smooth ground, and the auger drill bit 310 is used on soil ground. The mounting block 304 is placed on the outside of the first threaded rod 302, and then the fixing pin 306 is inserted into the mounting block 304 and the first threaded rod 302. The limiting bead 308 is squeezed and slides into the inside of the fixing pin 306. The limiting bead 308 squeezes the spring 307. When the fixing pin 306 is installed in place, the spring 307 drives the limiting bead 308 to slide, thereby preventing the fixing pin 306 from falling off. By turning the knob 303, the knob 303 drives the first threaded rod 302 to rotate. The threaded rod 302 drives the mounting block 304 to rotate, which in turn drives the fixed suction cup 305 or the auger drill bit 310 to rotate. This allows the fixed suction cup 305 to adhere to a smooth surface, or the auger drill bit 310 to rotate into the soil, thus fixing the device in place. After fixing, the drive motor 402 is started, which drives the second threaded rod 403 to rotate. The second threaded rod 403 drives the first sprocket 404 to rotate, which in turn drives the chain 405 to rotate. The chain 405 drives the second sprocket 406 to rotate, which in turn drives another set of second threaded rods 403 to rotate. Both sets of second threaded rods 403 rotate simultaneously, causing the support column 407 to move inside the guide column 401. The support column 407 causes the electronic display screen 408 to rise or fall, thus adjusting the height of the electronic display screen 408. The canopy 409 at the top of the electronic display screen 408 provides shade from sunlight or rain.

[0020] Through the above steps, the universal wheel 2 is rolled by the pushing device, thereby moving the device. After moving to the designated position, the pull ring 309 is pulled, which drives the fixing pin 306 to move. The limiting bead 308 is squeezed and slides into the inside of the fixing pin 306, thereby pulling out the fixing pin 306. Then, the fixing suction cup 305 and the auger drill bit 310 are replaced as needed. The fixing suction cup 305 is used on smooth ground, and the auger drill bit 310 is used on soil ground. The mounting block 304 is fitted over the outside of the first threaded rod 302, and then the fixing pin 306 is inserted into the mounting block 304 and the first threaded rod 302, limiting the movement of the device. The positioning bead 308 is squeezed and slides into the inner side of the fixing pin 306. The positioning bead 308 squeezes the spring 307. After the fixing pin 306 is installed in place, the spring 307 drives the positioning bead 308 to slide, thereby preventing the fixing pin 306 from falling off. By rotating the knob 303, the knob 303 drives the first threaded rod 302 to rotate. The first threaded rod 302 drives the mounting block 304 to rotate. The mounting block 304 drives the fixing suction cup 305 or the auger drill bit 310 to rotate, so that the fixing suction cup 305 is attached to the smooth ground, or the auger drill bit 310 is rotated into the soil, thereby fixing the device. After fixing is completed.
