Technical Field

[0001] The invention relates to the technical field of visual communication equipment, in particular to a visual communication device capable of preventing from being overturned by external force. Background Art

[0002] The term visual communication became popular at the World Design Conference held in Tokyo, Japan in 1960. Its content includes: the design of newspapers, magazines, posters and other printed promotional materials, as well as film, television, electronic billboards and other media. The expressive design that conveys relevant content to the eyes and shapes them is collectively called visual communication. Existing visual communication devices mainly use displays to display product-related content for users to watch.

[0003] At present, in actual use, the visual communication device (display) for exhibitions is mainly supported and fixed by a steel bracket. At this time, the overall center of gravity of the visual communication device (display) is located on the upper side, and the contact area between the support frame and the ground is limited, which causes the visual communication device (display) to be easily offset or tipped over when subjected to external force, thereby affecting the normal use of the device. To this end, in view of the above problem, a visual communication device that can prevent toppling due to external force is designed to better meet the actual use needs. Summary of the invention

[0004] The object of the present invention is to provide a visual communication device that is resistant to tipping over by external forces, so as to solve the problem in the above-mentioned background technology that the existing visual communication device is easily deflected or tipped over by external forces.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a visual communication device that prevents tipping due to external force, comprising a base plate, a vertical pole, a fixed pole, a mounting plate and a display, wherein the outer side of the base plate is provided with supporting feet, the vertical pole is vertically fixed to the center position of the upper end surface of the base plate, the vertical pole and the fixed pole are connected to each other, a cross bar is fixed at an equal angle to the outer side of the fixed pole, a mounting plate parallel to the base plate is fixed to the upper end of the fixed pole, a display is fixed to the upper end surface of the mounting plate, and a movable frame is provided on the front side of the display.

[0006] Preferably, four suction cups are fixed at equal angles on the lower end surface of the base plate, and an air guide tube is fixed on the upper end of the suction cup, and the air guide tube runs through the base plate, one end of a spring is fixed at the center position of the upper end surface of the base plate, and the other end of the spring is fixed to the lower end surface of the fixing rod, when the device is placed, the suction cup can be used to achieve adsorption with the ground, thereby fixing the entire device and preventing the device from sliding, and with the action of the air guide tube, the air between the suction cup and the ground can be discharged conveniently, and the suction cup and the ground can be adsorbed conveniently, and the elastic action of the spring can provide a basic force for the automatic resetting of the base plate.

[0007] Preferably, there are four supporting legs distributed at equal angles with respect to the center of the base plate, and a sliding rod is fixed to the side of the supporting leg close to the base plate, and the sliding rod and the base plate are slidably connected, and a rollable ball is also installed on the lower end surface of the supporting leg. When the supporting leg moves, the sliding guiding action between the sliding rod and the base plate can ensure that the supporting leg makes stable linear motion, and the rolling action of the ball in contact with the ground can reduce the friction between the supporting leg and the ground, making it easier for the supporting leg to move, and the supporting area between the entire device and the ground can be increased through the supporting leg, thereby realizing the anti-dumping effect of the device and ensuring the stability of the device.

[0008] Preferably, the vertical pole and the fixed pole are slidably connected, and a horizontal plate is fixed to the upper end of the vertical pole, and the horizontal plate is nested in the groove on the fixed pole and can slide up and down, and at the same time, the horizontal plate contacts with the upper end of the groove on the fixed pole to achieve a limiting effect. Through the sliding action between the vertical pole and the fixed pole, a basic guarantee can be provided for the normal operation of the entire device, and the sliding action between the horizontal plate and the fixed pole can provide a basic guarantee for the movement of the movable frame, and the positioning effect can be achieved through the contact and limit between the horizontal plate and the upper end of the groove on the fixed pole.

[0009] Preferably, a circular ring is fixed to the end of the horizontal rod away from the fixed rod, and four vertical rods are fixed at equal angles on the lower end surface of the circular ring, and a sealing ball is fixed to the lower end of the vertical rod. At the same time, the sealing balls and the air ducts are distributed in a one-to-one correspondence, and the sealing balls cooperate with the air duct to achieve a sealing effect. After the device is placed, the sealing of the air duct can be achieved by cooperating with the sealing balls and the air duct, thereby preventing outside air from entering, thereby ensuring the stability of the suction cup's adsorption to the ground.

[0010] Preferably, one end of the support rod is rotatably connected to the outer side of the circular ring, and the other end of the support rod is rotatably connected to the upper end surface of the support leg, and the support rod and the support leg are distributed in a one-to-one correspondence. When the vertical pole and the fixed pole slide, the distance between the circular ring and the support leg is reduced.

[0013] Preferably, a fixing plate is fixed to one side of the movable frame close to the display by bolts, and a sponge pad is fixed to one side of the fixing plate close to the display, and the length of the sponge pad is greater than the height of the display, and the sponge pad can slide in contact with the display. When the movable frame moves, the sponge pad is driven to move, and dust and flying catkins on the surface of the display can be cleaned through the contact and sliding action between the sponge pad and the display, thereby ensuring that the surface of the display is clean.

[0014] Preferably, the lower end of the movable frame is rotatably connected to one end of a connecting rod, and the other end of the connecting rod is rotatably connected to the horizontal plate, and the connecting rod passes through the mounting plate and can slide, and at the same time, the length of the connecting rod is greater than half the width of the display. When the horizontal plate moves, the transmission action of the connecting rod can provide a basic force for the movement of the movable frame, and by limiting the length of the connecting rod, the moving distance of the movable frame can be guaranteed, thereby preventing the movable frame from blocking the display.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the visual communication device that prevents tipping due to external forces adopts a gravity-automatic unfolding mechanism, which can cause the supporting feet to unfold outwards through the device's own gravity after the device is placed, thereby effectively increasing the supporting area of ​​the device and improving the device's anti-tipover ability. It can also be automatically stored during transportation, making it convenient to carry the device.

[0024] See also Figure 1-Figure 6 The present invention provides a technical solution: a visual communication device that can prevent being overturned by external force, comprising a base plate 1, a vertical pole 3, a fixed pole 4, a mounting plate 7 and a display 8, wherein a support leg 2 is arranged on the outer side of the base plate 1, a vertical pole 3 is vertically fixed to the center position of the upper end surface of the base plate 1, the vertical pole 3 and the fixed pole 4 are connected to each other, a cross bar 5 is fixed at an equal angle to the outer side of the fixed pole 4, a mounting plate 7 parallel to the base plate 1 is fixed to the upper end of the fixed pole 4, a display 8 is fixed to the upper end surface of the mounting plate 7, and a movable frame 9 is arranged on the front side of the display 8.

[0025] Four suction cups 101 are fixed at equal angles on the lower end surface of the bottom plate 1, and an air guide tube 102 is fixed on the upper end of the suction cup 101, and the air guide tube 102 runs through the bottom plate 1, one end of a spring 103 is fixed at the center position of the upper end surface of the bottom plate 1, and the other end of the spring 103 is fixed to the lower end surface of the fixing rod 4; there are four legs 2 distributed at equal angles about the center of the bottom plate 1, and a sliding rod 201 is fixed on one side of the legs 2 close to the bottom plate 1, and the sliding rod 201 is slidably connected to the bottom plate 1, and a rolling ball 20 is also installed on the lower end surface of the legs 2 2; a circular ring 501 is also fixed to one end of the horizontal bar 5 away from the fixed bar 4, and four vertical bars 502 are fixed at equal angles on the lower end surface of the circular ring 501, and a sealing ball 503 is fixed to the lower end of the vertical bar 502, and the sealing ball 503 and the air guide tube 102 are distributed one-to-one, and the sealing ball 503 cooperates with the air guide tube 102 to achieve a sealing effect; one end of the support rod 6 is rotatably connected to the outer side of the circular ring 501, and the other end of the support rod 6 is rotatably connected to the upper end surface of the support leg 2, and the support rod 6 and the support leg 2 are distributed one-to-one;

[0026] When using the visual communication device to prevent tipping due to external force, if Figure 1As shown in the figure, the whole device is in the storage state, which is convenient for carrying and storing the device. Figure 1-Figure 6 As shown, by placing the device on the ground, the suction cup 101 is in contact with the ground. Under the gravity of the entire device, the suction cup 101 can be deformed and adsorbed to the ground. At this time, the ball 202 is in contact with the ground, and the air between the suction cup 101 and the ground is discharged outward through the air guide tube 102. At this time, under the gravity of the mounting plate 7 and the display 8, the fixing rod 4 can be forced to move downward. With the sliding effect between the fixing rod 4 and the vertical rod 3, the stability of the movement of the fixing rod 4 can be ensured. When the fixing rod 4 moves downward, the spring 103 is forced to shrink, and the downward movement of the fixing rod 4 synchronously drives the cross bar 5, the ring 501, the vertical rod 502 and the sealing ball 503 to move downward. At this time, the support rod 6 connected to the ring 501 is forced to rotate, and the support foot 2 can be driven by the transmission effect of the support rod 6. The force slides outward, and the rolling effect between the ball 202 and the ground can reduce the friction between the support leg 2 and the ground, making it easier for the support leg 2 to move. The sliding guide effect between the slide bar 201 and the bottom plate 1 can ensure that the support leg 2 can move linearly stably until the sealing ball 503 moves down and nests with the opening at the upper end of the air guide tube 102 to achieve sealing, thereby achieving the support leg 2 The support area of ​​the device can be increased by the support leg 2, thereby improving the device's anti-dumping ability and ensuring the stability of the device. After the sealing ball 503 cooperates with the air guide tube 102 to achieve sealing, a negative pressure mechanism is formed between the suction cup 101 and the ground, thereby ensuring the stability of the suction cup 101 adsorbed on the ground, thereby achieving the fixing effect of the device and preventing the device from sliding due to external forces;

[0027] The vertical rod 3 and the fixed rod 4 are slidably connected, and a horizontal plate 301 is fixed on the upper end of the vertical rod 3, and the horizontal plate 301 is nested in the groove on the fixed rod 4 and can slide up and down, and at the same time, the horizontal plate 301 contacts the upper end of the groove on the fixed rod 4 to achieve a limiting effect; two vertical plates 701 are vertically fixed symmetrically on the upper end surface of the mounting plate 7, and a guide rod 702 is fixed between the two vertical plates 701, and the guide rod 702 and the mounting plate 7 are parallelly distributed; the movable frame 9 is symmetrically distributed about the center line of the mounting plate 7, and the movable frame 9 is slidably connected to the guide rod 702, and the guide rod 702 is parallel to the mounting plate 7. The length of 02 is greater than the width of the display 8; a fixing plate 901 is fixed to the side of the movable frame 9 close to the display 8 by bolts, and a sponge pad 902 is fixed to the side of the fixing plate 901 close to the display 8, and the length of the sponge pad 902 is greater than the height of the display 8, and the sponge pad 902 contacts the display 8 and can slide; the lower end of the movable frame 9 is rotatably connected to one end of a connecting rod 10, and the other end of the connecting rod 10 is rotatably connected to the horizontal plate 301, and the connecting rod 10 penetrates the mounting plate 7 and can slide, and the length of the connecting rod 10 is greater than half of the width of the display 8;

[0028] When the fixing rod 4 moves downward, Figure 1-Figure 6 As shown, at this time, the horizontal plate 301 slides upward in the groove on the fixed rod 4, so that the end of the connecting rod 10 connected to the horizontal plate 301 is forced to move and rotate, and through the transmission action of the connecting rod 10, the two movable frames 9 can be forced to slide outward, and the fixed plate 901 and the sponge pad 902 can be driven to slide outward synchronously, and the sliding guiding action between the movable frame 9 and the guide rod 702 can ensure the stability of the movement of the movable frame 9, the fixed plate 901 and the sponge pad 902, and through the action of the sponge pad 902, the dust and catkins on the surface of the display 8 can be cleaned to ensure the cleanliness of the surface of the display 8. When the horizontal plate 301 moves to contact the upper end of the groove on the fixed rod 4 to achieve positioning, the sealing ball 503 just cooperates with the air guide tube 102 to achieve sealing, and the movable frame 9 just moves to contact the vertical plate 701, so that the sponge pad 902 is separated from the display 8, thereby effectively avoiding the sponge pad 902 from blocking the display 8 and affecting the normal video playback effect of the display 8. According to the above principle, After the device is used, an upward force is applied to the mounting plate 7 to move the fixing rod 4 upward, thereby driving the sealing ball 503 to move upward a certain distance, so that the sealing ball 503 is separated from the air guide tube 102, releasing the sealing effect, and facilitating the outside air to enter between the suction cup 101 and the ground through the air guide tube 102, thereby facilitating the separation of the suction cup 101 from the ground. Finally, the elastic action of the spring 103 can automatically reset the entire device. At this time, the two sponge pads 902 move toward each other, and the sponge pads 902 can be used to clean the dust and catkins on the surface of the display 8 again. During long-term use, when the sponge pad 902 is damaged, the sponge pad 902 can be replaced by removing the fixing plate 901. In the process of cleaning the dust and catkins on the surface of the display 8, volatile liquids such as alcohol can be sprayed on the surface of the sponge pad 902 to keep the sponge pad 902 in a wet state to ensure the cleaning effect of the sponge pad 902 on the display 8. This is the working principle of the visual communication device that prevents tipping by external force.
