Description

Technical Field

[0001] This utility model belongs to the field of civil engineering construction technology and relates to lighting devices, specifically a pole-mounted lighting device for civil engineering construction. Background Technology

[0002] Pole-mounted lighting devices for civil construction are equipment used to provide temporary or localized lighting during civil construction. They can be easily moved to different construction locations according to the construction progress and site requirements. They have specific requirements for lighting intensity and range, and the height of the pole can be adjusted to meet the needs of different construction scenarios.

[0003] The working environment at civil construction sites is relatively complex, requiring large-scale lighting devices with high intensity and wide illumination range. These devices are often bulky and inconvenient to carry. This invention proposes a portable, detachable, modular lighting device. Through its detachable structure, the lighting device can be used easily. A transparent lampshade is installed on one side of the lamp base, but a gap exists between the lampshade and the lamp base to prevent phototactic flying insects from entering the lamp base. The accumulation of these insects inside the lamp base would obstruct the transparent lampshade and thus affect the lighting function of the lamp base. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a pole-mounted lighting device for civil engineering construction. This device employs a detachable connection method, allowing for convenient assembly and disassembly according to actual needs, thus enhancing its adaptability and meeting the demands of complex working environments and high-intensity lighting requirements in civil engineering construction sites. Simultaneously, the sealed assembly and disassembly method prevents phototactic insects from entering the lamp holder, thus avoiding the phenomenon where insect bodies accumulate inside the lamp holder, obstructing the transparent lampshade and affecting the lighting effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pole-mounted lighting device for civil construction, comprising a movable base, a support rod installed at the center of the movable base, a lamp holder installed at the top of the support rod, an LED bead installed inside the lamp holder, a limiting protrusion ring provided on the inner wall of the lamp holder, a transparent lamp cover installed above the limiting protrusion ring, and the transparent lamp cover being pressed and fixed above by an annular pressure plate.

[0006] Furthermore, a hollow rubber ring is provided between the annular pressure plate and the transparent lampshade.

[0007] Furthermore, four sets of L-shaped mounting seats are detachably installed on the outer periphery of the bottom of the lamp holder, and four sets of slots are provided on the corresponding side wall of the lamp holder; four protrusions are evenly provided on the outer periphery of the annular pressure plate, and the protrusions are located in the slots and are opposite to the corresponding L-shaped mounting seats. A sealing device for fixing is installed between the two sets of protrusions and the L-shaped mounting base, and a spring-loaded device for easy disassembly is installed between the other two sets of protrusions and the L-shaped mounting base.

[0008] Furthermore, the sealing device includes a rectangular rod and a rectangular tube. The rectangular rod is fixedly installed on the lower surface of the protrusion, and the rectangular tube is fixedly installed on the surface of the L-shaped mounting base. The rectangular rod is slidably installed inside the rectangular tube. The upper part of the rectangular tube has a threaded hole, and a positioning bolt is installed in the threaded hole. The positioning bolt passes through the threaded hole and abuts against the surface of the rectangular rod. By fixing the rectangular rod, the annular pressure plate presses the transparent lampshade tightly.

[0009] Furthermore, a rubber strip for increasing friction is adhered to the contact surface between the rectangular rod and the positioning bolt.

[0010] The aforementioned components achieve the following effects: The annular pressure plate is pressed, causing it to compress the hollow rubber ring, deforming it until it fills the gap between the transparent lampshade and the lamp holder; and the outer surface of the hollow rubber ring completely abuts against the inner wall of the lamp holder and the transparent lampshade. The position of the rectangular rod relative to the rectangular tube is determined; a positioning bolt is inserted into the threaded hole of the rectangular tube, and the positioning bolt is pressed against the rubber strip on one side of the rectangular rod. Tightening the positioning bolt achieves a seal between the hollow rubber ring and the connection between the transparent lampshade and the lamp holder, which helps prevent flying insects from entering the device and affecting the lighting of the lamp holder.

[0011] Furthermore, the spring extension device includes a spring and a fixing rod; the spring is disposed between the L-shaped mounting base and the protrusion, and a fixing rod for limiting and guiding is inserted inside the spring, with one end of the fixing rod fixed to the bottom surface of the protrusion.

[0012] Furthermore, the other end of the fixing rod passes through the L-shaped mounting base and is fixed by a fixing nut.

[0013] The aforementioned components achieve the following effect: when the annular pressure plate compresses the hollow rubber ring, it also compresses the spring, causing the spring to deform. When it is necessary to disassemble the transparent lampshade, loosen the positioning bolts, remove the force applied to the annular pressure plate by the sealing device, loosen the fixing nut, and the spring will return to its original position, moving the annular pressure plate away from the transparent lampshade, making it easier to disassemble the transparent lampshade.

[0014] Installation process of this utility model: During installation, pushing the annular pressure plate causes it to move downwards within the slot. This causes the rectangular rod to slide against the inner wall of the rectangular tube, compressing the spring and hollow rubber ring of the spring extension device. Both the spring and the hollow rubber ring deform until the outer surface of the hollow rubber ring fully abuts against the inner wall of the transparent lampshade and lamp holder, and one side of the transparent lampshade fully abuts against one side of the hollow rubber ring. Rotating the positioning bolt allows one end to pass through the threaded hole on the inner wall of the rectangular tube until it abuts against the rubber strip on one side of the rectangular rod. This fixes the position between the rectangular rod and the rectangular tube, thus securing the annular pressure plate and preventing loosening of the rubber ring. This achieves the fixation and sealing of the transparent lampshade and lamp holder.

[0015] During disassembly, rotate the positioning bolt in the opposite direction to loosen the fixation on the rectangular rod. The annular pressure plate will lose its restraint. Loosen the fixing nut, and the spring will return to its original position, causing the annular pressure plate to move away from the transparent lampshade. Remove the L-shaped mounting bracket from the lamp holder, allowing the annular pressure plate to completely detach from the lamp holder, thus completing the disassembly of the transparent lampshade.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This utility model adopts a detachable connection method, making the lighting device more convenient and adaptable, and meeting the needs of large-scale lighting devices with high lighting intensity and wide lighting range in the complex working environment of civil construction sites.

[0017] This invention uses a sealing device to compress the rubber ring, filling the gap between the transparent lampshade and the lamp holder. This ensures that the outer surface of the rubber ring is in complete contact with the inner wall of the lamp holder and the transparent lampshade, thus sealing the connection between the transparent lampshade and the lamp holder. This effectively prevents flying insects from entering the device and optimizes its lighting effect. Attached Figure Description

[0024] 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.

[0025] Example: Reference Figure 1-4 The illustrated pole-mounted lighting device for civil construction includes a movable base 1, a support rod 2 installed at the center of the movable base 1, a lamp holder 3 installed at the top of the support rod 2, an LED bead 31 installed inside the lamp holder 3, a limiting protrusion ring 32 provided on the inner wall of the lamp holder 3, a transparent lamp cover 4 installed above the limiting protrusion ring 32, a hollow rubber ring 6 provided above the transparent lamp cover 4, and an annular pressure plate 5 for pressing and fixing above the hollow rubber ring 6.

[0026] like Figure 2 As shown in Figure 4, four sets of L-shaped mounting bases 71 are detachably installed on the outer periphery of the bottom of the lamp holder 3, and four sets of slots 33 are provided on the corresponding side wall of the lamp holder 3, which facilitates the disassembly and assembly of the transparent lamp cover 4 and the annular pressure plate 5, thereby facilitating the internal inspection and maintenance of the device. The annular pressure plate 5 has four protrusions 51 evenly distributed on its outer periphery, which are located within the slots 33 and opposite to the corresponding L-shaped mounting bases 71. A sealing device 7 for fixing is installed between the two sets of opposing protrusions 51 and the L-shaped mounting bases 71, and a spring-loaded device 8 for easy disassembly and assembly is installed between the other two sets of protrusions 51 and the L-shaped mounting bases 71.

[0027] Specifically: Pushing the annular pressure plate 5 can move the annular pressure plate 5 toward the transparent lampshade 4. At this time, the annular pressure plate 5 will squeeze the hollow rubber ring 6, causing the hollow rubber ring 6 to deform until the outer surface of the hollow rubber ring 6 is completely in contact with the transparent lampshade 4 and the transparent lampshade 4 is completely in contact with the limiting protrusion ring 32, thus completing the fixation and sealing between the transparent lampshade 4 and the lamp holder 3.

[0028] like Figure 4As shown, the sealing device 7 includes a rectangular rod 73 and a rectangular tube 72. The rectangular rod 73 is fixedly installed on the lower surface of the protrusion 51, and the rectangular tube 72 is fixedly installed on the surface of the L-shaped mounting base 71. The rectangular rod 73 is slidably installed inside the rectangular tube 72. A threaded hole is provided at the upper part of the rectangular tube 72, and a positioning bolt 721 is installed in the threaded hole. The positioning bolt 721 passes through the threaded hole and abuts against the surface of the rectangular rod 73. A rubber strip 731 for increasing friction is adhered to the abutment surface on this side. The rubber strip 731 increases the friction between the positioning bolt 721 and the rectangular rod 73, making the fixation between the positioning bolt 721 and the rectangular rod 73 more secure. The positioning bolt 721, by fixing the rectangular rod 73, causes the annular pressure plate 5 to press the transparent lampshade 4 tightly.

[0029] Specifically: The annular pressure plate 5 is pressed down, causing it to compress the hollow rubber ring 6, deforming it until it fills the gap between the transparent lampshade 4 and the lamp holder 3; and the outer surface of the hollow rubber ring 6 is in complete contact with the inner wall of the lamp holder 3 and the transparent lampshade 4. The position of the rectangular rod 73 relative to the rectangular tube 72 is determined; a positioning bolt 721 is inserted into the threaded hole of the rectangular tube 72, and the positioning bolt 721 is pressed onto the rubber strip 731 on one side of the rectangular rod 73. Tightening the positioning bolt 721 achieves a seal between the hollow rubber ring 6 and the connection between the transparent lampshade 4 and the lamp holder 3, which helps prevent flying insects from entering the device and affecting the lighting of the lamp holder.

[0030] like Figure 4 As shown, the spring extension device 8 includes a spring 81 and a fixing rod 82; the spring 81 is disposed between the L-shaped mounting base 71 and the protrusion 51, and the fixing rod 82 for limiting and guiding is inserted inside the spring 81. One end of the fixing rod 82 is fixed to the bottom surface of the protrusion 51, and the other end passes through the L-shaped mounting base 71 and is fixed by a fixing nut 83.

[0031] Specifically: When the annular pressure plate 5 presses the hollow rubber ring 6, it also presses the spring 81, causing the spring 81 to deform. When it is necessary to disassemble the transparent lampshade 4, loosen the positioning bolt 721, remove the force applied by the sealing device 5 to the annular pressure plate 5, loosen the fixing nut 83, and the spring 81 will return to its original position, moving the annular pressure plate 5 away from the transparent lampshade 4, making it easier to disassemble the transparent lampshade 4.

[0032] Please see Figures 1-4 The installation process of a pole-mounted lighting device for civil engineering construction is as follows: During installation, pushing the annular pressure plate 5 causes it to move downwards within the slot 33. This causes the rectangular rod 73 to slide against the inner wall of the rectangular tube 72, compressing the spring 81 and hollow rubber ring 6 of the spring extension device 8. Both the spring 81 and the hollow rubber ring 6 deform until the outer surface of the hollow rubber ring 6 fully abuts against the inner wall of the transparent lampshade 4 and the lamp holder 3, and one side of the transparent lampshade 4 fully abuts against one side of the hollow rubber ring 6. Rotating the positioning bolt 721 allows one end to pass through the threaded hole on the inner wall of the rectangular tube 72 until it abuts against the rubber strip 731 on one side of the rectangular rod 73. This fixes the position between the rectangular rod 73 and the rectangular tube 72, thus securing the annular pressure plate 5 and ensuring that the pressure of the annular pressure plate 5 on the rubber ring 6 does not loosen, thus achieving the fixation and sealing of the rubber ring 6 on the transparent lampshade 4 and the lamp holder 3.

[0033] During disassembly, rotate the positioning bolt 721 in the opposite direction to loosen the fixation on the rectangular rod 73. The annular pressure plate 5 loses its limit, and the fixing nut 83 is loosened. The spring 81 will return to its original position, causing the annular pressure plate 5 to move away from the transparent lamp cover 4. Remove the L-shaped mounting bracket 71 from the lamp holder 3, so that the annular pressure plate 5 is completely separated from the lamp holder 3, thus completing the disassembly of the transparent lamp cover 4.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
