Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a floodlight housing. Background Technology

[0002] Floodlights are widely used in outdoor lighting, industrial site lighting, and other scenarios. Their housing, as the core protective structure of the luminaire, directly determines the luminaire's lifespan and safety. Outdoor and industrial environments commonly contain impurities such as rainwater, dust, and moisture. If the housing seal fails, these impurities can easily penetrate the internal contact wires and electrical components, potentially causing short circuits and other safety hazards, accelerating component aging, and severely reducing the luminaire's reliability.

[0003] Current floodlight housings typically consist of a junction box, lamp housing, lamp shade, and mounting bracket. Wires must pass through wiring holes on the junction box and lamp housing to establish internal circuitry. However, current designs for connecting the junction box and lamp housing often use directly aligned through-holes. Wires pass directly through these holes without any dedicated sealing design, relying solely on the natural fit between the components for a seal. This rudimentary structure offers extremely poor sealing performance, easily creating gaps at the wiring holes. Rainwater, dust, and other impurities can easily penetrate the housing through these gaps, and the wires are also at risk of being exposed through these gaps, failing to meet the protection requirements for complex and harsh environments.

[0004] Therefore, in view of the technical defects of existing floodlight housing junction boxes and lamp housings, such as poor sealing performance and easy exposure of wires, there is an urgent need for a floodlight housing with an optimized sealing structure to improve the sealing and protection effect. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention provides a floodlight housing.

[0006] The technical solution adopted by this utility model is: a floodlight housing, including a junction box, a cover fitted on the junction box, a lamp housing, a lamp shade connected to the lamp housing, and a mounting bracket set on the junction box. The junction box is provided with a first wiring hole, and the lamp housing is provided with a second wiring hole that is directly opposite to the first wiring hole. The outer ring of the first wiring hole is provided with a first protruding ring and a second protruding ring. The inner wall of the first protruding ring and the inner and outer walls of the second protruding ring are provided with annular grooves, and a sealing ring is installed in the annular groove. The second wiring hole has a sleeve extending toward the first wiring hole. The top of the sleeve is provided with a fitting annular groove, which fits into the second convex ring. The connecting ring outside the fitting annular groove is embedded between the first convex ring and the second convex ring.

[0007] Furthermore, the upper side of the sealing ring is provided with an inlet inclined surface, and the lower side is provided with several annular protrusions spaced apart.

[0008] Furthermore, the outer wall of the junction box is provided with a plurality of positioning grooves at intervals, and a mounting ring is provided in the positioning groove. The mounting ring is provided with mounting holes, and the lamp housing is provided with mounting shafts that correspond one-to-one with the positioning grooves. The mounting shaft is provided with screw holes that correspond to the mounting holes.

[0009] Furthermore, both the junction box and the lamp housing are cylindrical structures, with several reinforcing ribs spaced apart on the outer wall of the junction box, and several heat dissipation fins spaced apart on the outer wall of the lamp housing.

[0010] Furthermore, both ends of the mounting bracket are rotatably connected to the junction box via ratchet wheels.

[0011] The beneficial effects of this utility model are: 1. Enhanced sealing and protection performance, adaptable to complex and harsh environments: This structure utilizes multiple interlocking fits between the first and second convex rings and the sleeve, with sealing rings installed in the annular grooves on both the inner and outer walls of the convex rings, forming multiple lines of sealing protection. The gap between the first and second convex rings, and the mating surfaces of the second convex ring and the sleeve's interlocking groove, are all tightly sealed by the sealing rings, effectively blocking the path of rainwater, dust, moisture, and other impurities from entering the housing through the wiring hole. The sealing reliability far exceeds that of traditional direct wiring structures, enabling the floodlight to stably adapt to harsh environments with high levels of impurities and humidity, such as outdoor and industrial sites.

[0012] 2. Avoiding the risk of exposed wires and improving safety: In this structure, the fitting ring groove at the top of the sleeve is precisely fitted with the second convex ring, and the connecting ring on the outside of the fitting ring groove is embedded between the first and second convex rings. With the sealing effect of multiple sealing rings, the channel through which the wires pass through forms a fully enclosed protective space. This structurally eliminates the problem of wires being exposed due to sealing failure, and at the same time avoids aging, short circuits and other faults caused by impurities coming into direct contact with the wires, greatly improving the safety of the lighting fixture.

[0013] 3. Stable and reliable structural fit, extending lamp life: The interlocking connection structure between the first and second convex rings and the sleeve not only achieves a sealing function but also enhances the structural stability of the connection between the junction box and the lamp housing. This interlocking fit effectively resists vibrations and external installation forces during lamp use, avoiding problems such as misalignment of wiring holes and increased sealing gaps that easily occur with traditional direct connections. The long-term stability of the sealing performance and the reliable fit of the structural connection together reduce the aging and wear of internal electrical components, significantly extending the overall lifespan of the floodlight.

[0014] 4. Simple and rational structural design, facilitating assembly and maintenance: The convex ring, sleeve, and fitting ring groove of this structure are all integrally molded. During assembly, simply align the sleeve with the gap between the first and second convex rings and insert it, ensuring a precise fit between the fitting ring groove and the second convex ring to complete the sealing assembly. This simple and efficient operation reduces the difficulty of production and assembly. Furthermore, the structural design of each sealing component facilitates disassembly and replacement of the sealing rings during later maintenance, eliminating the need for destructive disassembly of the main structure and improving maintenance convenience.

[0015] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0024] This utility model provides a floodlight housing.

[0025] In this embodiment, refer to Figure 1-5 The floodlight housing includes a junction box 1, a cover 2 that fits over the junction box 1, a lamp housing 3, a lamp shade 4 connected to the lamp housing 3, and a mounting bracket 5 set on the junction box. The junction box is provided with a first wiring hole 6, and the lamp housing is provided with a second wiring hole 6 that is directly opposite to the first wiring hole. The outer ring of the first wiring hole is provided with a first protruding ring 7 and a second protruding ring 8. The inner wall of the first protruding ring and the inner and outer walls of the second protruding ring are provided with annular grooves 9. A sealing ring 10 is installed in the annular grooves 9. The second wiring hole has a sleeve 11 extending toward the first wiring hole. The top of the sleeve 11 is provided with a fitting annular groove 12, which fits into the second convex ring. The connecting ring 13 on the outside of the fitting annular groove is embedded between the first convex ring and the second convex ring.

[0026] In the above technical solution, the sealing problem at the junction box and lamp housing wiring area is solved by constructing a nested sealing structure of "convex ring-sleeve": a coaxial first and second convex ring are set on the outer ring of the first wiring hole of the junction box. Annular grooves are machined on the key contact surfaces of the convex rings (inner wall of the first convex ring, inner wall of the second convex ring, and outer wall) and sealing rings are assembled to form a multi-dimensional seal. Simultaneously, a sleeve extending towards the first wiring hole is set at the second wiring hole of the lamp housing. Through the double nesting design of the sleeve's top fitting annular groove and the second convex ring engaging, and the outer connecting ring embedding into the gap between the two convex rings, the wiring hole connection area forms a "convex ring-sleeve" interlocking structure, which, together with multiple sets of sealing rings, achieves complete sealing of the contact surface. This nested engagement and multiple sealing rings form a triple sealing defense, preventing the intrusion of rainwater, dust, and other impurities, thus improving waterproof and dustproof performance.

[0027] Specifically, the upper side of the sealing ring is provided with an inlet inclined surface 14, and the lower side is provided with several annular protrusions 15 spaced apart.

[0028] In this embodiment, an inlet ramp is provided on the upper side. The guiding effect of the ramp reduces the contact resistance between the sealing ring and the convex ring and sleeve during assembly, enabling rapid alignment. Multiple annular protrusions are provided at intervals on the lower side. The elastic deformation of the protrusions during assembly and compression increases the contact pressure between the sealing ring and the annular groove and mating surface, while forming multiple independent sealing surfaces to further improve the sealing effect.

[0029] Specifically, the outer wall of the junction box is provided with a plurality of positioning grooves 17 at intervals, and a mounting ring 18 is provided in the positioning groove 17. The mounting ring 18 is provided with mounting holes 19. The lamp housing is provided with mounting shafts 20 corresponding to the positioning grooves one by one, and the mounting shaft is provided with screw holes 21 corresponding to the mounting holes.

[0030] In this embodiment, positioning grooves are provided at intervals on the outer wall of the junction box and mounting rings with mounting holes are assembled. Mounting shafts are provided at corresponding positions on the lamp housing and screw holes are machined. Initial positioning is achieved through the cooperation of the positioning grooves and mounting rings. Then, bolts are used to pass through the mounting holes and screw holes to form a detachable rigid fixing structure, ensuring that the sealing parts always remain in a close fit.

[0031] Specifically, both the junction box and the lamp housing are cylindrical structures. The outer wall of the junction box is provided with several reinforcing ribs 22 at intervals, and the outer wall of the lamp housing is provided with several heat dissipation fins 23 at intervals.

[0032] In this embodiment, the junction box and lamp housing are designed as cylindrical structures, utilizing the mechanical advantages of the cylindrical shape to optimize the stress distribution; the outer wall of the junction box is provided with reinforcing ribs, which enhance the radial strength of the housing through the support of the ribs; the outer wall of the lamp housing is provided with heat dissipation fins, which increase the contact area with air and accelerate the heat conduction inside the lamp housing through air convection, thereby achieving a synergistic improvement in structural strength and heat dissipation performance.

[0033] Specifically, both ends of the mounting bracket are rotatably connected to the junction box via ratchet 24.

[0034] In this embodiment, a ratchet mechanism is used to achieve the rotatable connection between the mounting bracket and the junction box. The ratchet's tooth groove meshing characteristic is utilized: the ratchet is fixed to the junction box, and a pawl is provided at the end of the mounting bracket. The rotational positioning of the bracket is achieved by the meshing of the pawl with the ratchet's tooth groove. The ratchet's one-way self-locking function ensures that the bracket's angle is fixed after adjustment, preventing angle deviation caused by external forces.

[0035] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
