Furthermore, the movably connected extension rod results in insufficient device stability, and the lack of a safe wiring device may pose a safety risk. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide an industrial plant lighting rod holder that solves the problems of complex manufacturing and assembly, insufficient stability, and lack of safe wiring devices caused by the complex structure of existing industrial and mining lamp mounting brackets.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An industrial plant lighting fixture includes a crossbeam support, an upper square frame, a hanging rod, a junction box, and a lower square frame. The two ends of the crossbeam support are fixedly installed on the steel beams of the plant. The middle section of the crossbeam support is fixedly connected to the upper end of the upper square frame. The lower end of the upper square frame is fixedly connected to the upper end of the hanging rod, and the lower end of the hanging rod is fixedly connected to the upper end of the lower square frame. A junction box is installed inside the lower square frame, and a lighting fixture is installed at the lower end of the lower square frame. The upper and lower square frames are spatially perpendicular to each other.

[0007] Furthermore, below the crossbeam support, the bottom surface of the steel beam of the factory building is fixedly provided with a clamping plate, and the square clamp passes through the crossbeam support and is fixed to the clamping plate by a locking nut.

[0008] Furthermore, the upper square frame is fixed to the crossbeam support by the first bolt and nut assembly, and the lower square frame is connected to the lamp by the third bolt and nut assembly.

[0009] Furthermore, the upper end of the boom is fixedly connected to the upper square frame via a boom upper lock nut, and the lower end of the boom is fixedly connected to the lower square frame via a boom lower lock nut.

[0010] Furthermore, the upper and lower square frames are respectively spliced ​​together by two U-shaped C-shaped flat steel bars. The upper and lower halves of the upper square frame are fixedly connected by the second bolt and nut assemblies on the left and right sides, and the upper and lower halves of the lower square frame are fixedly connected by the fourth bolt and nut assemblies on the left and right sides.

[0011] Furthermore, the first bolt and nut assembly, the second bolt and nut assembly, the third bolt and nut assembly, and the fourth bolt and nut assembly all use anti-lock nuts.

[0012] Furthermore, the bottom of the crossarm support has bolt holes and is made of C-shaped steel.

[0013] Furthermore, a junction box is provided inside the lower square frame, and the suspension rod passes through the junction box and is fixed with a lock nut.

[0014] Furthermore, the suspension rod is a tubular structure made of galvanized material.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to specific embodiments. The description is for explanation and not limitation of the present invention.

[0024] like Figure 1 , 3 As shown, an industrial plant lighting fixture includes a crossbeam support 1, an upper square frame 2, a suspension rod 3, a junction box 4, and a lower square frame 5. The two ends of the crossbeam support 1 are fixedly installed on the steel beams of the plant. The middle section of the crossbeam support 1 is fixedly connected to the upper end of the upper square frame 2. The lower end of the upper square frame 2 is fixedly connected to the upper end of the suspension rod 3. The lower end of the suspension rod 3 is fixedly connected to the upper end of the lower square frame 5. The junction box 4 is installed inside the lower square frame 5. A lighting fixture 6 is installed at the lower end of the lower square frame 5. The upper square frame 2 and the lower square frame 5 are perpendicular to each other in space, which can firmly fix the lighting fixture in a designated position, ensuring that the lighting fixture will not shake or fall during operation. Especially in industrial environments with vibration or wind, this ensures the stability and safety of the lighting.

[0025] Below the crossbeam support 1, two clamping plates 12 are fixedly installed on the bottom surface of the steel beam of the factory building. The two clamping plates 12 protrude from each other for a certain length. A square clamp 11 passes through the crossbeam support 1 and is fixed to the protruding part of the clamping plate 12 by a locking nut. The crossbeam support 1 is fixed to the end face of the steel beam of the factory building using the square clamp 11 and the special clamping plates 12. The clamping plates 12 must be aligned and tightened.

[0026] like Figure 2 As shown, the upper square frame 2 is fixed to the crossbeam support 1 by the first bolt and nut assembly 21, and the lower square frame 5 is connected to the light fixture by the third bolt and nut assembly 51. The upper end of the hanger 3 is fixedly connected to the upper square frame 2 by the hanger upper lock nut 31, and the lower end of the hanger 3 is fixedly connected to the lower square frame 5 by the hanger lower lock nut 32. The upper square frame 2 and the lower square frame 5 are respectively spliced ​​by two U-shaped C-shaped flat steel bars interlocked vertically. The upper and lower halves of the upper square frame 2 are fixedly connected by the second bolt and nut assemblies 22 on the left and right sides, and the upper and lower halves of the lower square frame 5 are fixedly connected by the fourth bolt and nut assemblies 52 on the left and right sides. This utility model only requires the use of bolts and nuts for fixing, which can effectively save installation time and labor costs.

[0027] The bottom of the crossbeam support 1 has bolt holes and is made of C-shaped steel.

[0028] A junction box 4 is installed within the lower square frame 5. The suspension rod 3 passes through the junction box 4 and is secured with a lock nut. The suspension rod 3 also serves as the power conduit for the light fixture. The junction box 4 is made of plastic. When the suspension rod 3 passes through the junction box 4 and wiring is performed, the junction box 4 isolates the wire connector from the external environment, preventing the metal conductor at the wire connector from contacting other objects and avoiding safety accidents such as short circuits or leakage, thus providing good insulation protection. Simultaneously, the junction box 4 provides physical protection for the internal wire connections, preventing damage to the wire connectors due to external factors such as mechanical collisions, friction, or pulling. Especially in factory buildings, without the protection of the junction box, wire connectors may loosen or detach due to vibration or impact, leading to circuit failures. The junction box 4 can fix the connectors in a relatively stable space, reducing this risk.

[0029] The first bolt and nut assembly 21, the second bolt and nut assembly 22, the third bolt and nut assembly 51, and the fourth bolt and nut assembly 52 all employ anti-loosening nuts for locking. Considering the operating environment of industrial and mining lamps, using anti-loosening nuts effectively prevents the nuts from loosening under vibration and impact, ensuring the stability of the connection. Furthermore, once installed and tightened, the anti-loosening nuts can maintain a tight state for a relatively long period, reducing the need for frequent inspections and tightening due to nut loosening, effectively reducing the risk of failure, and improving reliability and service life.

[0030] The suspension rod 3 is a tubular structure made of galvanized material. The galvanized layer can form a dense protective film on the metal surface, providing reliable protection for the steel pipe, extending the service life of the suspension rod, and also serving as a conduit for the power supply of the lighting fixtures.

[0031] This invention enables rapid assembly using pre-fabricated bracket components, and the hanging height is controlled by adjusting the length of the hanging rod 3. Simultaneously, the hanging rod 3 also functions as a conduit, allowing the lighting cable to pass through the crossarm bracket 1, the upper square frame 2, and through the hanging rod 3, ultimately connecting to the lighting power cord at the junction box 4. This design ensures concealed wiring and safe protection of the connection points. The bracket is easy to install, and the square frame design in two directions reduces the swaying of the lighting fixture, making it simple to operate, convenient to use, and widely applicable.
