Abstract

This utility model relates to a field of expertise, particularly to a wind- and earthquake-resistant, stable outdoor lightbox, comprising a main compartment, a mounting slot, a motor, a lead screw, a slider, a fixing plate, an electric push rod, a heating plate, an advertising cloth, a damper, a base plate, a spring, and a guide plate. The main compartment has mounting slots on both its left and right front sides. A motor is mounted on the upper left side of the main compartment, with its output end connected to a lead screw that passes through the upper end of the main compartment. The lower end of the lead screw is rotatably connected to the lower end of the left mounting slot. This utility model utilizes a motor to drive the lead screw to rotate, which in turn restricts the slider's rotation via the left mounting slot, causing it to move. This movement of the fixing plate and connecting parts further facilitates the movement of the fixed plate and connecting parts. The electric push rod and heating plate first clamp and heat-press the advertising cloth, then repeatedly iron it flat. The guide plate disperses wind force, the spring stores energy upon impact, and the damper converts vibration into heat energy to suppress rebound, achieving wind and earthquake resistance while ensuring the advertising cloth is flattened.

Description

Technical Field

[0001] This utility model relates to the field of wind and earthquake resistant and stable outdoor light box. Background Technology

[0002] Outdoor light boxes are a type of outdoor advertising equipment. They feature high brightness and all-weather visibility. Made of waterproof and rustproof materials and equipped with a stable power supply system, they can withstand rain, snow, and high temperatures. They are widely used in commercial advertising, shop signs, road signs, and bus stop signs. They attract attention with dynamic or static images, enhance brand exposure and information delivery, and have advantages such as energy saving, durability, and easy maintenance. They also help improve the city's image and boost the nighttime economy.

[0003] Existing sturdy outdoor light boxes lack ironing and wind and shock resistance functions. Without these functions, the advertising cloth may dent at the back when subjected to external impact, and the main compartment may sway under the influence of wind and external impact. This results in the advertising cloth becoming unsightly at the back after long-term use and affects the installation stability of the main compartment.

[0004] Therefore, given that existing stable outdoor light boxes lack ironing and wind and shock resistance functions, and that the advertising cloth dents when impacted and the main compartment sways under wind and external impact, resulting in unsightly back ends of the advertising cloth after long-term use and affecting the installation stability of the main compartment, there is an urgent need to design a new type of wind and shock resistant stable outdoor light box. Utility Model Content

[0005] To overcome the problems of existing sturdy outdoor light boxes lacking ironing and wind and shock resistance, the advertising cloth being dented upon impact and the main compartment swaying under the influence of wind and external impacts, resulting in unsightly back ends of the advertising cloth after long-term use and affecting the installation stability of the main compartment.

[0006] The technical solution of this utility model is as follows: a wind-resistant and earthquake-resistant stable outdoor lightbox, including a main compartment; it also includes a mounting groove, a motor, a lead screw, a slider, a fixing plate, an electric push rod, a heating plate, an advertising cloth, a damper, a base plate, a spring, and a guide plate. Mounting grooves are provided on both the left and right front sides of the main compartment. A motor is installed on the upper left side of the main compartment. The output end of the motor passes through the upper end of the main compartment and is connected to a lead screw. The lower end of the lead screw is rotatably connected to the lower end of the left mounting groove. A slider is threaded onto the outer surface of the lead screw. Block 1 and slider 1 are mounted on the right rear side of a fixed plate 1. Electric push rods are mounted on the left and right sides of the rear end of fixed plate 1. The telescopic ends of the two electric push rods pass through the rear end of fixed plate 1 and are connected to a heating plate. An advertising cloth is placed between the heating plate and fixed plate 1. Dampers are mounted at the four corners of the rear end of the main compartment. A base plate is mounted at the rear end of the four dampers. One end of a spring is mounted on the front end of the base plate outside the four dampers. The other end of the four springs is connected to the rear end of the main compartment. Guide plates are mounted on the four sides of the main compartment.

[0007] Preferably, by setting a motor, the motor drives the lead screw to rotate. When the lead screw rotates, it restricts the rotation of the slider 1 through the left mounting slot, thereby driving the slider 1 to move. When the slider 1 moves, it drives the fixed plate 1 and its connected parts to move together. Before moving, the electric push rod and heating plate are activated to bring the heating plate and fixed plate 1 close together to clamp the advertising cloth for ironing. Then, the advertising cloth is ironed as a whole by reciprocating movement, thereby achieving the purpose of keeping the advertising cloth flat. By setting a guide plate, the air blown towards the main chamber is directed elsewhere, thereby reducing interference to the main chamber. Furthermore, by setting a damper and spring, the air blown towards the main chamber is directed elsewhere. After being impacted by an external force, the spring first absorbs the impact energy through elastic deformation and stores and releases kinetic energy. When releasing kinetic energy, the damper generates resistance through the internal viscous fluid, converting the vibration kinetic energy into heat energy and suppressing the excessive vibration when the spring rebounds. This achieves the purpose of wind and earthquake resistance, solving the problem that existing stable outdoor light boxes lack ironing and wind and earthquake resistance functions. Without these functions, the advertising cloth may dent at the rear end when impacted by an external force, and the main compartment may sway under the influence of wind and external impact forces. This leads to problems such as the advertising cloth becoming unsightly at the rear end after long-term use and the installation stability of the main compartment being affected.

[0008] Preferably, a limiting rod is installed at the upper end of the inner side of the right mounting groove, and a slider two is slidably connected to the outer surface of the limiting rod. The left end of the slider two is connected to the right end of the fixing plate one.

[0009] Preferably, the main compartment has mounting slots 2 on both the upper and lower front sides. Knobs are rotatably connected to the middle of the upper and lower front sides of the main compartment. The rear ends of the two knobs are connected to screws through the front end of the main compartment. The rear ends of the screws are rotatably connected to the rear end of the mounting slot 2. A movable plate is threaded onto the outer surface of the screws. Fixed plates 2 are installed on the upper and lower sides of the main compartment at the rear of the mounting slot 2. The movable plates and fixed plates 2 on the upper and lower sides are attached to one end of the corresponding advertising cloth.

[0010] Preferably, a rocker arm is mounted on the front end of each of the two knobs, and a handle is rotatably connected to the left side of the front end of each of the two rocker arms.

[0011] As a preferred option, the main compartment has three sets of lamp holders installed at the rear, with lamp tubes connected between each set of lamp holders.

[0012] Preferably, several ventilation slots are provided at the middle of the rear end of the main compartment, and a radiator is installed at the rear end of the main compartment behind the ventilation slots.

[0013] Preferably, the bottom plate is equipped with symmetrical mounting plates on both the top and bottom surfaces, and bolts are installed inside each of the four mounting plates.

[0014] Preferably, the outer surface of each of the four bolts is threaded with a nut, and the radiator is provided with three nuts.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting up a motor, the motor transmits rotational kinetic energy to the lead screw. When the lead screw performs rotational motion, under the circumferential rotation restriction of the slider 1 in the mounting slot, the rotational motion of the lead screw is converted into the axial displacement of the slider 1. The slider 1 drives the fixed plate 1 and its connecting parts through a rigid connection to form a synchronous motion trajectory. Before moving, the electric push rod and heating plate are activated. The heating plate forms a dynamic clamp with the fixed plate 1 under the drive of the electric push rod, applies preset pressure to the advertising cloth and performs contact heating, forming a clamping and heating composite ironing mode. Subsequently, under the continuous drive of the motor, it performs reciprocating motion along the surface of the advertising cloth. Through the dual action of heat conduction and mechanical flattening, the wrinkles of the advertising cloth are eliminated, thereby achieving the purpose of keeping the advertising cloth flat.

[0017] 2. By setting up a motor and a deflector, the airflow path of the main compartment on the windward side is reconstructed, achieving active isolation of the airflow environment in the main compartment. Then, by setting up a damper and a spring, when the main compartment is subjected to external impact loads, the spring first completes the absorption and storage of impact energy through the elastic deformation stage, forming an elastic energy storage mechanism. In the energy release stage, the damper converts the vibration kinetic energy released by the spring into heat energy dissipation through the throttling effect generated by the internal viscous fluid during piston movement. Through this two-stage energy conversion mechanism, the oscillation aftershocks when the spring rebounds are effectively suppressed, thereby achieving the purpose of wind and earthquake resistance.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-5This utility model provides an embodiment of a wind- and earthquake-resistant stable outdoor lightbox, comprising a main compartment 1; and further comprising a mounting groove 2, a motor 3, a lead screw 4, a slider 5, a fixing plate 6, an electric push rod 7, a heating plate 8, an advertising cloth 9, a damper 10, a base plate 11, a spring 12, and a guide plate 13. Mounting grooves 2 are provided on both the left and right front sides of the interior of the main compartment 1. A motor 3 is installed on the upper left side of the main compartment 1. The output end of the motor 3 passes through the upper end of the main compartment 1 and is connected to the lead screw 4. The lower end of the lead screw 4 is connected to the lower end of the interior of the left mounting groove 2. A rotating connection is made, with a slider 5 threaded onto the outer surface of the lead screw 4. A fixing plate 6 is installed on the rear right side of the slider 5. Electric push rods 7 are installed on both the left and right sides of the rear end of the fixing plate 6. The telescopic ends of the two electric push rods 7 pass through the rear end of the fixing plate 6 and are connected to a heating plate 8. An advertising cloth 9 is placed between the heating plate 8 and the fixing plate 6. Damperes 10 are installed at the four corners of the rear end of the main compartment 1. A base plate 11 is installed at the rear end of the four dampers 10. One end of a spring 12 is installed at the front end of the base plate 11, located outside the four dampers 10. The other end of each spring 12 is connected to the rear end of the main compartment 1. Guide plates 13 are installed on all four sides of the main compartment 1. A motor 3 is installed, which drives the lead screw 4 to rotate. When the lead screw 4 rotates, it restricts the rotation of the slider 5 through the left mounting slot 2, thereby moving the slider 5. When the slider 5 moves, it moves the fixed plate 6 and its connected parts together. Before moving, the electric push rod 7 and the heating plate 8 are activated, bringing the heating plate 8 and the fixed plate 6 close together to clamp the advertising cloth 9 for ironing. Then, through reciprocating movement... The advertising cloth 9 is ironed as a whole to keep it flat. By setting up the deflector 13, the wind blowing towards the main chamber 1 is directed elsewhere, thereby reducing interference to the main chamber 1. Then, by setting up the damper 10 and the spring 12, after the main chamber 1 is impacted by an external force, the spring 12 first absorbs the impact energy by elastic deformation and stores and releases the kinetic energy. When releasing the kinetic energy, the damper 10 generates resistance through the internal viscous fluid, converting the vibration kinetic energy into heat energy and suppressing the excessive vibration when the spring 12 rebounds, thereby achieving the purpose of wind and earthquake resistance.

[0026] Please see Figures 1-5In this embodiment, a limiting rod 14 is installed at the upper end of the inner side of the right mounting slot 12. A slider 2 15 is slidably connected to the outer surface of the limiting rod 14. The left end of the slider 2 15 is connected to the right end of the fixed plate 16. By setting the slider 2 15, since the slider 2 15 is connected to the fixed plate 16, the fixed plate 16 moves and drives the slider 2 15 to move. The limiting rod 14 constrains the degree of freedom of the slider 2 15, thereby providing support for the other end of the fixed plate 16, so as to make the movement of the fixed plate 16 more stable. Mounting slots 2 16 are opened on the front sides of the upper and lower sides of the inner side of the main compartment 1. A knob 17 is rotatably connected to the middle position of the upper and lower sides of the front end of the main compartment 1. The rear ends of the two knobs 17 pass through the front end of the main compartment 1 and are connected to a screw 18. The rear end of the screw 18 is rotatably connected to the rear end of the inner side of the mounting slot 2 16. A movable plate 1 is threadedly connected to the outer surface of the screw 18. 9. The interior of the main compartment 1 has two fixed plates 20 installed on the rear side of the mounting groove 2 16 on both the upper and lower sides. The movable plates 19 on the upper and lower sides and the fixed plates 20 are attached to one end of the corresponding advertising cloth 9. By setting the knob 17, turning the knob 17 drives the screw 18 to rotate. When the screw 18 rotates, it restricts the rotation of the movable plate 19 through the mounting groove 2 16, thereby driving the movable plate 19 to move. When the movable plate 19 and the fixed plate 20 are attached, the advertising cloth 9 can be clamped and installed, thereby achieving the purpose of installing the advertising cloth 9. The front end of each of the two knobs 17 is equipped with a rocker arm 21. The left side of the front end of each of the two rocker arms 21 is rotatably connected to a handle 22. By setting the rocker arm 21, the torque applied to the knob 17 can be increased. By setting the handle 22, the operator can have a grip point when turning the rocker arm 21, thereby achieving the purpose of easily turning the knob 17.

[0027] Please see Figures 1-4In this embodiment, three sets of lamp holders 23 are installed at the rear end of the main compartment 1, and each set of lamp holders 23 is connected to a lamp tube 24. By setting the lamp tubes 24, when the lamp tubes 24 are turned on, they transmit uniform and strong light through the translucent advertising cloth 9, making the picture colors bright and the details clear, displaying the advertising content with high brightness in a dark environment, thereby enhancing the display effect of the advertising cloth 9. Several ventilation slots 25 are opened in the middle of the rear end of the main compartment 1. A radiator 26 is installed behind the ventilation slots 25 at the rear end of the main compartment 1. By setting the ventilation slots 25, the air inside the main compartment 1 can be exchanged with the outside. By setting the radiator 26, the air exchange volume can be further increased, thereby achieving heat dissipation inside the main compartment 1. The purpose is to install symmetrical mounting plates 27 on both the upper and lower surfaces of the base plate 11. Each of the four mounting plates 27 has a bolt 28 inside. After confirming the installation position, the bolt 28 is passed through the middle of the mounting plate 27 and screwed into the mounting surface, thereby clamping the mounting plate 27 and fixing it in place. The outer surface of each of the four bolts 28 is threaded with a nut 29. The radiator 26 has three nuts 29. After the bolt 28 is screwed into the mounting surface, the nut 29 is screwed into the tail of the bolt 28 until the nut 29 fits against the mounting surface, thereby locking the bolt 28 with the thread and further improving the installation strength.

[0028] During operation, the main chamber 1 is first installed at the target location using bolts 28, mounting plate 27, and nuts 29. Then, the knob 17 is rotated using rocker arm 21 and crank handle 22 to fix the two ends of the advertising cloth 9 to the movable plate 19 and fixed plate 20. Then, the lamp tube 24 is turned on to make the advertising cloth 9 bright. When the advertising cloth 9 is dented due to an external impact, the motor 3, electric push rod 7, and heating plate 8 are started to clamp the advertising cloth 9 and move back and forth to iron it flat. During this process, the limit rod 14 and slider 2 15 provide support for the movement of the fixed plate 1 6. In windy weather or after being impacted by external forces, the airflow is guided by the guide plate 13, and the impact energy is absorbed and released by the cooperation between the spring 12 and the damper, reducing the impact of external factors on the installation stability. After the lamp tube 24 has been running for a long time, heat accumulates inside the main chamber 1. The internal heat is transferred out through the ventilation slot 25 and radiator 26 to dissipate heat.

[0029] Through the above steps, by setting up motor 3, when motor 3 drives lead screw 4 to rotate, the left mounting slot 2 forms a circumferential constraint on slider 5, converting the rotational motion into axial displacement of slider 5, thereby driving the fixed plate 6 and its connecting parts to move as a whole. Before moving, the electric push rod 7 and heating plate 8 are activated. Through linear propulsion, the heating plate 8 and fixed plate 6 form a pressure-adjustable clamping pair, implementing contact heat pressing and shaping on the advertising cloth 9. Subsequently, under the transmission of lead screw 4, a planar reciprocating ironing motion is performed, using the dual effects of heat conduction and mechanical flattening to eliminate wrinkles. By setting up guide plate 13, the external airflow of the main chamber 1 is directionally diverted, reducing wind pressure interference. By setting up a damper 10 and a spring 12, when the main chamber 1 is impacted, the spring 12 absorbs and stores primary energy through elastic deformation. During the energy release phase, the damper 10 uses the shear resistance of viscous fluid to convert the remaining kinetic energy into heat dissipation, suppressing the excessive vibration when the spring 12 rebounds. This solves the problem that existing stable outdoor light boxes lack ironing and wind and shock resistance functions. Without these functions, the advertising cloth 9 may dent at the rear end when impacted by external forces, and the main chamber 1 may sway under the influence of wind and external impact forces. This results in the advertising cloth 9 becoming unsightly at the rear end after long-term use and the installation stability of the main chamber 1 being affected.
