Description

Technical Field

[0001] This utility model relates to the field of LED advertising machine technology, specifically a foldable LED advertising machine with a deflector. Background Technology

[0002] With its advantages of high brightness, wide viewing angle, long lifespan, and dynamic display effects, LED advertising machines have been widely used in commercial complexes, outdoor streets, exhibition venues, transportation hubs, and other scenarios, becoming a core carrier for brand promotion and information dissemination. As the demand for mobile displays continues to increase, foldable LED advertising machines, due to their convenient transportation and small storage space, are gradually replacing traditional fixed equipment and becoming one of the mainstream trends in the market.

[0003] However, existing folding LED advertising machines still have technical defects in practical applications: the folding process lacks an effective buffer structure, and the upper and lower metal frames of the folding frame are prone to hard collisions when folding, resulting in frame dents, paint peeling, and seriously shortening the service life of the equipment.

[0004] To address these issues, this invention provides a foldable LED advertising machine with a deflector. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a foldable LED advertising machine with a deflector, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a folding LED advertising machine with a deflector, comprising a folding frame divided into upper and lower parts, which are rotatably connected by a hinge. A base is fixedly installed at the bottom of the folding frame. The folding frame is also provided with a crossbar for mounting an LED display screen by bolts. It also includes a buffer mechanism installed on the inner side of the folding frame. The buffer mechanism includes a deflector fixedly connected to the folding frame. The output end of the deflector is fixedly connected to a steel wire through a connecting frame. The steel wire passes through the upper and lower parts of the folding frame, and a locking buckle is fixedly connected to the outer side of the end of the steel wire.

[0007] Preferably, the upper and lower parts of the folding frame are symmetrically provided with through holes that penetrate the upper and lower parts. Both ends of the through holes are fixedly connected with pads, and a roller is rotatably connected between the two pads. The steel wire is set on the outside of the roller.

[0008] Preferably, the upper and lower parts of the folding frame are provided with through holes for connecting wires between the upper and lower parts.

[0009] Preferably, the connection between the upper and lower parts of the folding frame is fixedly connected with a cushioning pad for buffering the impact force when the folding frame is folded and for providing room for movement at the connection between the upper and lower parts.

[0010] Preferably, a sealing strip for sealing the connection between the upper and lower parts of the folding frame is fixedly connected at the connection point.

[0011] Preferably, the side of the folding frame is provided with a latching mechanism for locking the upper and lower parts when the folding frame is unfolded. The latching mechanism includes mounting grooves formed on the upper and lower sides of the folding frame. The mounting grooves are provided with a male latch and a female latch, and the male latch and the female latch are respectively located on the upper and lower parts of the folding frame. Beneficial effects

[0012] This invention provides a foldable LED advertising machine with a deflector. Compared with the prior art, it has the following advantages: (1) The folding LED advertising machine with a deflector achieves stability during the folding process and protects the equipment structure by using a deflector, connecting frame, steel wire, pads and rollers in the through holes at the connection points of the folding frame, and buffer pads installed on the inside of the folding frame. The deflector applies damping force to the steel wire through the connecting frame, which can effectively slow down the folding speed and avoid impact caused by folding too fast; the pads can stably support the positioning rollers and prevent the rollers from shifting, while the rollers convert the sliding friction between the steel wire and the inner wall of the through hole into rolling friction, reducing the wear of the steel wire and ensuring its smooth movement; the buffer pads can absorb the impact force of the collision between the upper and lower parts of the folding frame during folding, preventing the metal frame from denting and the paint from peeling off, while reserving a clearance to prevent jamming, significantly improving the safety and service life of the equipment during folding operation.

[0013] (2) The folding LED advertising machine with a deflector achieves stable locking and protection of the core components of the equipment after the folding frame is unfolded through the buckle mechanism on the side of the folding frame and the sealing strip and wire hole at the connection of the folding frame. The male and female buckles are tightly engaged in the mounting groove, which can firmly lock the upper and lower parts of the unfolded folding frame and prevent accidental folding caused by external forces (such as collisions and wind), ensuring that the LED display screen displays the advertising content flat. The sealing strip fits the connection gap and can block dust, rainwater and other impurities from entering the interior of the folding frame, preventing the buffer mechanism, wires and other components from rusting or short-circuiting. The wire hole centrally stores the connecting wires of the LED display screen, avoiding the wires from being exposed and damaged, and improving the reliability of the equipment.

[0016] 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.

[0017] Please see Figure 1 - Figure 8 A foldable LED advertising machine with a deflector includes a folding frame 1, which is divided into upper and lower parts and is rotatably connected by a hinge 7. A base 3 is fixedly installed at the bottom of the folding frame 1. A crossbar 6 for mounting an LED display screen 2 by bolts is also provided on the folding frame 1. The machine also includes a buffer mechanism 5, which is installed on the inner side of the folding frame 1. The buffer mechanism 5 includes a deflector 51 fixedly connected to the folding frame 1. A steel wire 53 is fixedly connected to the output end of the deflector 51 through a connecting frame 52. The steel wire 53 passes through the upper and lower parts of the folding frame 1. A locking buckle 57 is fixedly connected to the outer side of the end of the steel wire 53.

[0018] Please see Figure 4 and Figure 5In an optional embodiment: the upper and lower parts of the folding frame 1 are symmetrically provided with through holes 54 that pass through the upper and lower parts. Both ends of the through holes 54 are fixedly connected with pads 55. A roller 56 is rotatably connected between the two pads 55. A steel wire 53 is provided on the outside of the roller 56.

[0019] It should be noted that during use, the pad 55 can provide stable support and positioning for the roller 56, preventing the roller 56 from shifting laterally or shaking inside the through hole 54, and ensuring that the roller 56 is always in the preset working position. During the unfolding or folding of the folding frame 1, the steel wire 53 will be displaced with the movement of the folding frame 1. At this time, the steel wire 53 will contact the surface of the roller 56 and drive the roller 56 to roll, reducing the wear of the steel wire 53 during the movement, extending the service life of the steel wire 53, and reducing the frictional resistance that hinders the movement of the steel wire 53. This ensures that the steel wire 53 can smoothly cooperate with the stopper 51 to achieve buffer adjustment, thereby ensuring that the buffering effect of the buffering mechanism 5 on the folding frame 1 is always stable and reliable.

[0020] Please see Figure 4 and Figure 5 In an optional embodiment, the upper and lower parts of the folding frame 1 are each provided with a through hole 9 that passes through the upper and lower parts and is used to connect the wires between the LED display screens 2.

[0021] It should be noted that the upper and lower LED displays 2 need to be connected by wires to achieve power supply or transmission of advertising content signals. The wire hole 9 can play a role in the centralized storage and guidance of these connecting wires: on the one hand, after the wires are passed through the wire hole 9, the wires will be constrained inside the folding frame 1, preventing exposed wires from being damaged or aged due to wind, rain, external pulling or friction, thus ensuring the continuity of power and signal transmission of the LED display 2; on the other hand, the centrally stored wires will not be messily tangled in the moving parts of the folding frame 1, which can prevent the wires from interfering with the folding and unfolding operation of the folding frame 1, ensuring the smoothness of the movement of the folding frame 1.

[0022] Please see Figure 4 and Figure 5 In an optional embodiment, a cushioning pad 10 is fixedly connected at the connection between the upper and lower parts of the folding frame 1 to buffer the impact force when the folding frame 1 is folded and to provide room for movement at the connection between the upper and lower parts.

[0023] It should be noted that when the folding frame 1 is transitioned from the unfolded state to the folded state, the connection between its upper and lower parts will gradually approach each other and may collide. The buffer pad 10 can absorb the impact force generated by the collision by its own elastic deformation, so as to prevent the metal frame of the folding frame 1 from being dented, deformed or having its paint peeled off due to hard impact. At the same time, the buffer pad 10 itself has a certain thickness, which can reserve a reasonable gap between the upper and lower parts of the folding frame 1, preventing the two from getting stuck or jammed due to excessive tightness during folding or unfolding, and ensuring that the opening and closing movement of the folding frame 1 is always flexible and stable.

[0024] Please see Figure 4 and Figure 5 In an optional embodiment, a sealing strip 8 for sealing the connection between the upper and lower parts of the folding frame 1 is fixedly connected to the connection point of the upper and lower parts.

[0025] It should be noted that the sealing strip 8 is made of elastic sealing material, which can tightly fit the connection gap between the upper and lower parts when the folding frame 1 is unfolded or folded. On the one hand, it can effectively block dust, sand, rain, moisture and other impurities in the external environment from entering the interior of the folding frame 1, and prevent the internal components from rusting, short-circuiting or failing due to impurities.

[0026] Please see Figure 3 and Figure 6 In an optional embodiment: the side of the folding frame 1 is provided with a latching mechanism 4 for locking the upper and lower parts when the upper and lower parts of the folding frame 1 are unfolded. The latching mechanism 4 includes a mounting groove 41 opened on the upper and lower sides of the folding frame 1. The mounting groove 41 is provided with a male latch 42 and a female latch 43, and the male latch 42 and the female latch 43 are respectively provided on the upper and lower parts of the folding frame 1.

[0027] It should be noted that when the upper and lower parts of the folding frame 1 are fully unfolded and in the advertising display working state, the operator can push the male buckle 42 located on the upper folding frame 1 into the female buckle 43 of the lower folding frame 1, so that the male buckle 42 and the female buckle 43 are tightly engaged in the mounting groove 41, thereby firmly locking the upper and lower parts of the folding frame 1. This prevents the advertising machine from being accidentally folded due to external impact, ground vibration or wind force during operation, ensuring that the LED display screen 2 always remains in a flat unfolded state and guarantees the complete display of advertising content. When it is necessary to store or move the advertising machine and fold the folding frame 1, simply pull the male buckle 42 outward to separate the male buckle 42 from the female buckle 43 to release the lock.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] Working principle: During operation, first pull the male buckle 42 outward to separate it from the female buckle 43, releasing the locking mechanism 4 on the upper and lower parts of the folding frame 1; manually push the upper and lower parts of the folding frame 1 to fold inward around the hinge 7; during the folding process, the deflector 51 of the buffer mechanism 5 generates a damping force on the steel wire 53 through the connecting frame 52, slowing down the folding speed; the steel wire 53 slides along the roller 56 in the through hole 54 of the folding frame 1, cooperating with the deflector 51 to achieve smooth folding; when the upper and lower parts of the folding frame 1 are close together, the buffer pad 10 at the connection uses elastic deformation to absorb the impact force of the collision, preventing the metal frame of the folding frame 1 from deforming due to hard collision, while leaving a clearance for movement to prevent folding jamming; after folding, the position of the steel wire 53 is fixed by the locking buckle 57 at the end of the steel wire 53 to keep the folding frame 1 in a folded state, which is convenient for subsequent handling or storage.

[0030] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
