Description

Technical Field

[0001] This utility model relates to the field of lightbox advertising technology, specifically to an outdoor windproof and dustproof sealed lightbox. Background Technology

[0002] The commonly known structure of outdoor windproof and dustproof sealed light boxes typically uses metal (such as aluminum alloy or stainless steel) or high-strength engineering plastics as the main frame, with the frame joints fixed by bolts or clips. The front of the light box usually uses tempered glass or polycarbonate sheet as the light-transmitting panel, and rubber or silicone sealing strips are embedded between the panel and the frame to achieve a basic seal. The interior of the light box is equipped with LED light source modules and power supply lines. Some products have detachable access doors at the bottom or side of the frame. In addition, to enhance wind resistance, the entire light box is fixed to the supporting structure such as walls and columns using expansion bolts. The overall design must meet the basic protection and structural stability requirements of outdoor environments.

[0003] During long-term use, the sealing strips inside outdoor windproof and dustproof sealed light boxes will gradually age and deform due to the effects of ultraviolet rays and alternating high and low temperatures. This will increase the gap between the panel and the frame, reduce the dustproof and waterproof capabilities, allow dust to enter the light box and accumulate, affecting the brightness of the light source, and allow rainwater to seep in and potentially damage the circuitry. In addition, the bolts at some of the light box frame splicing points are prone to loosening due to long-term vibration, resulting in slight deformation of the frame, which in severe cases can lead to cracking of the light-transmitting panel. Utility Model Content

[0004] The purpose of this utility model is to provide an outdoor windproof and dustproof sealed light box to solve the problems mentioned in the background art, such as the sealing strip gradually aging and deforming due to the influence of ultraviolet rays and alternating high and low temperatures, which leads to an increase in the gap between the panel and the frame, a decrease in dustproof and waterproof capabilities, dust entering and accumulating inside the light box affecting the brightness of the light source, rainwater seepage and potential damage to the circuit, and the bolts at some of the light box frame splicing points are prone to loosening due to long-term vibration, resulting in slight deformation of the frame, and in severe cases, cracking of the light-transmitting panel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an outdoor windproof and dustproof sealed light box, including a main frame, which is the main frame structure of the light box. The bottom end of the main frame is installed in the groove on the top surface of the support base, and the support base is the main support structure for supporting the light box. The rectangular surface of the main frame has a strip groove, and a magnetic strip is installed in the strip groove by a spring. The magnetic strip is magnetically attracted to the surface of the sealing mounting plate. The sealing mounting plate covers the opening of the main frame, and a sealing element is provided at the connection between the main frame and the sealing mounting plate. The support base has mounting holes, and a battery is embedded in the upper end of the mounting holes. The battery is placed on the upper layer of the ventilated support frame, and the lower layer of the ventilated support frame abuts against the top surface of the heat sink. The heat sink has heat dissipation holes. The battery powers the LED light strip, and the LED light strip is set along the height direction on the inner wall of the main frame.

[0006] Using the above technical solution, the ventilated support frame, together with the heat dissipation plate, achieves efficient heat dissipation of the battery, avoiding heat accumulation that could affect power supply. The main frame and the support base are fitted together to increase the wind resistance of the foundation.

[0007] Preferably, the side walls of the main frame are each equipped with a side auxiliary bracket, and the side auxiliary bracket is configured as a T-shaped structure that fits into the groove at the top of the support base.

[0008] Using the above technical solution, the T-shaped side auxiliary bracket is snapped onto the base and fixed to the frame, which strengthens the rigidity of the connection between the frame and the base and improves wind resistance stability.

[0009] Preferably, the inner wall of the main frame is embedded with a positioning display installation frame, and there are two positioning display installation frames, which are symmetrically arranged with the LED light strip as the center line.

[0010] Using the above technical solution, the two positioning display installation frames are symmetrically set with LED light strips, so that the light can evenly cover the display content, avoid the problem of uneven brightness on one side, improve the display clarity, and adapt to the needs of double-sided display.

[0011] Preferably, the main frame has an internal mounting cavity on one side, and the battery is embedded in the mounting cavity. The side wall of the mounting cavity has a wire hole, and a sealing sleeve is provided in the wire hole. The wire of the LED light strip passes through the sealing sleeve and is electrically connected to the battery.

[0012] By adopting the above technical solution, the cavity-encapsulated battery is installed with a sealing sleeve for the wiring hole, which prevents the wires from being exposed and water from entering, while fixing the position of the battery and ensuring the stability of power supply.

[0013] Preferably, the support base is configured as a trapezoidal platform structure, and ground anchor positioning cylinders are provided on both sides of the support base. The ground anchor positioning cylinders are provided with through holes in the axial direction for the ground anchors to pass through.

[0014] By adopting the above technical solution, the trapezoidal platform base improves the overall stability, and the ground anchor positioning cylinder transmits force to the foundation through the ground anchor, effectively improving the wind resistance.

[0015] Preferably, the positioning display mounting frame is configured as a rectangular frame structure, and the positioning display mounting frame is located on the side close to the sealing mounting plate, and the sealing mounting plate is made of metal material, with a ferromagnetic layer on the side close to the magnetic strip.

[0016] By adopting the above technical solution, the rectangular positioning display installation frame is easy to adapt to various display materials, and the ferromagnetic layer of the sealed installation plate strengthens the fit with the magnetic strip, thereby improving the sealing reliability.

[0017] Preferably, the sealed mounting plate encapsulates a light-transmitting display panel, and the light-transmitting display panel is arranged parallel to the positioning display mounting frame, and the edge of the light-transmitting display panel is flush with the edge of the front opening of the main frame.

[0018] Using the above technical solution, the light-transmitting display panel is encapsulated in a sealed mounting plate and flush with the frame, taking into account both light transmission and sealing. Furthermore, the parallel arrangement ensures the visual flatness of the displayed content.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This outdoor windproof and dustproof sealed light box: 1. The main frame of this device has a magnetic strip installed in the groove by a spring. This magnetic strip, together with a metal sealing plate with a ferromagnetic layer, forms a double sealing structure with an elastic magnetic joint seal. The spring provides a continuous elastic pre-tightening force to the magnetic strip. Even if the seal is slightly aged due to ultraviolet rays and alternating high and low temperatures, the magnetic strip can still fit tightly against the sealing plate, preventing the gap between the panel and the frame from widening. The light-transmitting display panel is encapsulated in the sealing plate with its edge flush with the front opening of the main frame, further blocking gaps and effectively preventing dust intrusion. This prevents the brightness of the light source from being affected by dust accumulation and also prevents rainwater from seeping in and damaging the circuit. 2. The support base adopts a trapezoidal platform structure to improve overall stability. The two side anchor positioning cylinders are rigidly connected to the foundation through the anchors, directly transferring the wind load to the foundation. The T-shaped side auxiliary brackets of the main frame side wall are inserted into the groove at the top of the support base to form a triangular stable support, thereby increasing the wind-resistant structure and further resisting slight deformation under strong wind impact. Combined with the flush sealing design of the light-transmitting display panel and the main frame, it effectively avoids the risk of cracking of the light-transmitting panel caused by frame deformation. 3. The battery in the device is embedded in the main frame mounting cavity. The wire hole sealing sleeve prevents water from entering at the wire connection. The ventilated support frame disperses the heat of the battery and transfers it to the heat dissipation plate with heat dissipation holes to achieve efficient heat dissipation and ensure the stable operation of the battery and LED light strip. The two positioning display mounting frames are symmetrically set with the LED light strip as the center line. Combined with the high light transmittance of the light-transmitting display panel, the uniformity of lighting of the display content is improved. The overall structure achieves the coordinated use of wind resistance, sealing, heat dissipation and display functions. Attached Figure Description

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.

[0023] Please see Figures 1-6 The present invention provides a technical solution: an outdoor windproof and dustproof sealed light box, including a main frame 1, a support base 2, a side auxiliary bracket 3, a battery 4, a breathable support frame 5, a heat sink 6, a ground anchor positioning cylinder 7, an LED light strip 8, a positioning display mounting frame 9, a magnetic strip 10, a sealed mounting plate 11, and a light-transmitting display plate 12. Among them, the main frame 1 is the main frame structure of the light box. The bottom end of the main frame 1 is installed in the groove on the top surface of the support base 2. The support base 2 is the main support structure for supporting the light box. A rectangular groove is formed within the main frame 1, and a magnetic strip 10 is installed within this groove via a spring. The magnetic strip 10 magnetically attracts the surface of the sealing mounting plate 11, which covers the opening of the main frame 1. A seal is provided at the connection between the main frame 1 and the sealing mounting plate 11. Side auxiliary supports 3 are installed on the side walls of the main frame 1, and the side auxiliary supports 3 are T-shaped structures that fit into the top groove of the support base 2. A positioning display mounting frame 9 is embedded in the inner wall of the main frame 1, and the positioning display mounting frame 9 is provided with two... Two positioning display mounting frames 9 are symmetrically arranged with the LED light strip 8 as the center line. The positioning display mounting frames 9 are set as rectangular frame structures and are located on the side near the sealing mounting plate 11. The sealing mounting plate 11 is made of metal and has a ferromagnetic layer on the side near the magnetic strip 10. The main frame 1 has an installation cavity inside one side and the battery 4 is embedded in the installation cavity. The side wall of the installation cavity has a wire hole and a sealing sleeve is provided in the wire hole. The wire of the LED light strip 8 passes through the sealing sleeve and is electrically connected to the battery 4. Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the support base 2 is placed in the installation position, and the anchor is fixed to the ground by passing through the anchor positioning cylinders 7 on both sides of the base. The bottom end of the main frame 1 is embedded into the groove at the top of the support base 2, and then the T-shaped side auxiliary bracket 3 is inserted into the groove, with its vertical section fixed to the side wall of the main frame 1, forming a wind-resistant support structure. Figures 2-4 As shown, the heat sink 6 is placed at the bottom of the mounting cavity of the main frame 1, and the ventilated support frame 5 is placed on top. The battery 4 is then embedded in the upper layer of the ventilated support frame 5. The battery 4 is a device model that can be recharged and connected to a charging cable. The cable is made by drilling a hole in the side wall of the support base 2 to facilitate continuous power supply from an external power source. The LED light strip 8 is fixed along the height direction of the inner wall of the main frame 1. The wire passes through the sealing sleeve of the wire hole in the mounting cavity and is connected to the battery 4. The two positioning display mounting frames 9 are symmetrically embedded into the inner wall of the main frame 1 with the LED light strip 8 as the center line. According to the display needs, the corresponding advertising display parts that cannot be displayed are fixed to the surface of the positioning display mounting frames 9 with bolts. The advertising display surface faces the light-transmitting display panel 12. The light-transmitting display panel 12 is encapsulated in the sealing mounting plate 11, aligned with the opening of the main frame 1 and closed, so that the spring-loaded magnetic strip 10 in the strip groove is magnetically attached to the ferromagnetic layer of the sealing mounting plate 11, and the sealing is completed in conjunction with the sealing component. The support base 2 has an installation hole, and the upper end of the installation hole is embedded with a battery 4. The battery 4 is placed on the upper layer of the ventilated support frame 5, and the lower layer of the ventilated support frame 5 abuts against the top surface of the heat sink 6. The heat sink 6 has heat dissipation holes. The battery 4 supplies power to the LED light strip 8, and the LED light strip 8 is set along the height direction on the inner wall of the main frame 1. The support base 2 is set as a trapezoidal platform structure, and ground anchor positioning cylinders 7 are set on both sides of the support base 2. The ground anchor positioning cylinder 7 has a through hole in the axial direction for the ground anchor to pass through. The sealing mounting plate 11 encapsulates a light-transmitting display plate 12, and the light-transmitting display plate 12 is set parallel to the positioning display mounting frame 9. The edge of the light-transmitting display plate 12 is flush with the edge of the front opening of the main frame 1. Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the battery 4 is started by connecting the control switch. The current is transmitted to the LED light strip 8 through the wire protected by the sealed sleeve. The light strip emits light along the height of the inner wall of the main frame 1. Observe whether the light evenly covers the positioning display installation frame 9 without any dark corners. The magnetic strip 10 is pre-tightened by the spring elasticity and continuously magnetically adheres to the sealed installation plate 11. It works with the seal to block outdoor dust and rain. The light-transmitting display plate 12 simultaneously seals the display surface to prevent the intrusion of debris. The heat generated by the operation of the battery 4 is dispersed by the grid structure of the breathable support frame 5 and conducted to the heat sink 6 and then quickly discharged through the heat dissipation holes. The breathable support frame 5 also supports the battery 4 to avoid direct contact with the heat sink 6, which would cause heat accumulation. Furthermore, the trapezoidal platform structure of the support base 2 disperses the wind load. The ground anchor positioning cylinder 7 transmits the force to the foundation through the ground anchor. The side auxiliary bracket 3 strengthens the connection between the main frame 1 and the base to resist the impact of gusts and strong winds. After a period of use, check if the anchor positioning cylinder 7 of the support base 2 is loose, and retighten the anchor bolts. If the side auxiliary bracket 3 is deformed, replace the T-shaped bracket and re-clamp it in place. Adjust the main frame 1 to a vertical position. In case of power failure, turn off the control switch, disconnect the wire connection between the battery 4 and the LED light strip 8, and remove the battery 4 for power loss protection. When it is necessary to replace the display part, open the sealing mounting plate 11, take out the display material in the positioning display mounting frame 9, and loosen the anchor bolts of the anchor positioning cylinder 7 by moving the screw rod as a whole. Remove the side auxiliary bracket 3 and separate the main frame 1 from the support base 2. In daily use, apply protective oil to the magnetic strip 10 and the seals, cover the light-transmitting display plate 12 with a protective film, and store each part in a dry environment to avoid aging and deformation caused by exposure to sunlight and moisture.

[0024] Working principle: When using this outdoor windproof and dustproof sealed light box, the ground anchor positioning cylinders 7 on both sides of the support base 2 are fixed to the ground by the ground anchor. The bottom end of the main frame 1 is embedded into the groove at the top of the support base 2. At the same time, the T-shaped structure of the side auxiliary bracket 3 is inserted into the groove and fixed to the side wall of the main frame 1 to form a windproof support structure. Next, the battery 4 is embedded in the mounting cavity of the main frame 1. The LED light strip 8 wires pass through the sealing sleeve of the wire hole in the mounting cavity and are connected to the battery 4 to power the light strip. The battery 4 is placed on the upper layer of the ventilated support frame 5. Its heat is dispersed through the ventilated support frame 5 and then discharged through the heat dissipation holes of the heat dissipation plate 6. The magnetic strip 10 in the strip groove of the main frame 1 is pre-tightened by the spring and magnetically attached to the ferromagnetic layer of the sealing mounting plate 11. The sealing of the light box is achieved with the sealing component. The edge of the light-transmitting display plate 12 is flush with the front opening of the main frame 1, and the display surface is sealed simultaneously. The LED light strip 8 is driven by the battery 4 to emit light along the height of the inner wall of the main frame 1. The light illuminates two positioning display mounting frames 9 that are symmetrically set with the light strip as the center line. The display content is presented through the light-transmitting display panel 12, realizing lighting display in an outdoor windproof, dustproof and sealed state, which increases the overall practicality.
