Description

Technical Field

[0001] This utility model relates to the field of lighting fixture technology, and in particular to an environmentally friendly component spraying booth. Background Technology

[0002] Lighting fixtures are indispensable equipment in production and daily life, widely used in various environments such as outdoors, factories, and tunnels. In these environments, lighting fixtures often face harsh conditions such as dust, moisture, and rain. Therefore, the protective performance of the fixture's housing, especially its dustproof and waterproof performance, is crucial to the stable operation and lifespan of its internal light source and circuitry.

[0003] To achieve dust and water resistance, existing technologies typically employ a sealed housing design. This design usually involves placing sealing rings or sealing strips at the joints where the housings mate, and then using bolts or other fasteners to press the various parts of the housing together to achieve a sealing effect.

[0004] However, this single sealing structure has inherent reliability issues in long-term use. Firstly, the seams between components, especially the top cover and other joints, are difficult to completely prevent the intrusion of moisture and dust in complex environments with just a single seal. Secondly, and more critically, when the light source inside the fixture needs repair or replacement, the entire casing must be disassembled. Repeated disassembly and reassembly can easily lead to deformation, aging, or damage to the sealing strip, significantly reducing or even completely negating the sealing performance after reassembly. This creates an irreconcilable conflict between the casing's protective reliability and ease of maintenance.

[0005] Therefore, this utility model proposes a dustproof and waterproof lighting housing to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems that existing dustproof and waterproof lighting housings have insufficient protective performance due to their simple sealing structure, and that the disassembly and assembly process is complicated and easily damages the seals when maintenance is required, this utility model aims to provide a dustproof and waterproof lighting housing with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a dustproof and waterproof lighting housing, including a first waterproof housing and a second waterproof housing that mates with the first waterproof housing. The first waterproof housing and the second waterproof housing together form an accommodating space. The lighting housing also includes a lamp holder, a retaining strip, a disassembly and assembly component, a dust cover, a first connecting strip, a second connecting strip, and a sealing component.

[0008] The lamp holder is set in the receiving space, and a slot is opened on its outer peripheral wall. The locking strip is fixedly connected to the inner wall of the first waterproof shell and the second waterproof shell respectively, and forms a sliding fit with the slot of the lamp holder.

[0009] Furthermore, the disassembly and assembly components, dust cover, connecting strip, and sealing component work together on the first and second waterproof shells to form a complete locking and sealing structure. The disassembly and assembly components include a fixed shell, a locking block fixedly connected to the outer wall of the waterproof shell, and a first bolt. The fixed shell is snapped onto the locking block from the outside and locked by the thread of the first bolt. The dust cover is placed on the top of the first and second waterproof shells. The first and second connecting strips are snapped together between the dust cover and the first and second waterproof shells. The second connecting strip has a fixedly connected insert block on its outer side. The insert block is inserted into the first connecting strip to form a cavity that matches the insert block. The first and second connecting strips are threadedly connected by the second bolt. The sealing component includes a sealing strip clamped at the mating edge of the first and second waterproof shells, a first sealing gasket pressed against the dust cover by the first connecting strip, and a second sealing gasket pressed against the top of the first and second waterproof shells by the second connecting strip.

[0010] Preferably, the lamp holder has a through-hole for mounting a light bulb in the middle.

[0011] More preferably, the inner wall of the mounting hole is provided with a mating structure for threaded connection or snap-fit ​​with the bulb.

[0012] Preferably, the lower edges of the first and second waterproof shells are integrally formed with downwardly extending insert edges, and the top outer wall of the dust cover is formed with a slot that mates with the insert edges.

[0013] Preferably, the fixed shell is a shell with a C-shaped cross-section along its length.

[0014] Preferably, the outer surface of the card block forms an arc surface that is adapted to the inner wall of the fixing shell.

[0015] Preferably, there are multiple second bolts, which are evenly distributed along the length of the first connecting strip.

[0016] Preferably, both the first sealing gasket and the second sealing gasket are elastic sealing rings.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem of unreliable sealing structure of existing lighting housings, especially the problem of water and dust ingress at component joints, by setting a sealing strip sandwiched at the joint edge of the first and second waterproof housings, and a double sealing structure composed of a first sealing gasket and a second sealing gasket pressed by the first connecting strip and the second connecting strip respectively. It achieves the technical effect of double sealing protection, greatly improves the overall dustproof and waterproof performance, and ensures the long-term stable operation of the lamp in harsh environments.

[0018] 2. This utility model solves the problem that existing lamp housings with good sealing properties are usually complex in structure, difficult to disassemble and assemble, and inconvenient for later maintenance or replacement of internal bulbs by setting a side disassembly and assembly component consisting of a fixed shell, a locking block, and a first bolt, and a top disassembly and assembly component consisting of a first connecting strip, a second connecting strip, an insert block, and a second bolt. It achieves the technical effect of modular structure and clear and convenient disassembly and assembly steps, allowing users to quickly and non-destructively open the shell for maintenance, thus improving the maintainability of the product.

[0019] 3. This utility model solves the problems of inaccurate positioning and loose structure of the outer shell components in the prior art, which may lead to sealing failure due to vibration and other reasons after long-term use, by locking the locking block to the fixed shell, positioning the insertion block to the connecting strip, and sliding the slot on the lamp holder to the locking strip on the inner wall of the waterproof shell. It achieves the technical effect of multi-point precise positioning and stable and reliable connection, ensuring high structural strength after assembly of each component and guaranteeing the long-term effectiveness of the sealing structure.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Example: Please refer to Figures 1 to 5 This utility model provides a dustproof and waterproof lighting housing, which aims to solve the problems of insufficient dustproof and waterproof performance and inconvenient disassembly and maintenance caused by the single sealing structure of the existing lighting housing.

[0024] like Figures 1 to 5 As shown, the basic frame of the dustproof and waterproof lighting housing is formed by the mating of the first waterproof shell 1 and the second waterproof shell 2. Together, they form an internal storage space for accommodating the bulb and related components. A sealing strip 901, serving as the first sealing structure, is sandwiched between the mating edges of the first waterproof shell 1 and the second waterproof shell 2. Inside the housing, a lamp holder 7 for mounting a light source is provided. In order to stably fix the lamp holder 7 in the housing, a retaining strip 8 is fixedly connected to the inner wall of the first waterproof shell 1 and the second waterproof shell 2 respectively. At the same time, a slot 10 adapted to the retaining strip 8 is opened on the outer peripheral wall of the lamp holder 7. During assembly, the lamp holder 7 slides in along the retaining strip 8, so that the retaining strip 8 and the slot 10 form a stable sliding fit relationship. In order to securely lock the first waterproof shell 1 and the second waterproof shell 2 together in the docking state, a disassembly assembly 6 is provided in the middle of the shell. The core part of the disassembly assembly 6 is that protruding locking blocks 602 are fixedly connected to the outer walls of the first waterproof shell 1 and the second waterproof shell 2 respectively. The fixing shell 601 with a C-shaped cross section along its length direction is engaged from the outside and covers the locking blocks 602 on both sides. Then, the fixing shell 601 and the locking blocks 602 are screwed in and threadedly locked by the first bolt 603, thereby applying a reliable radial locking force to the entire shell. On top of the basic frame, a dust cover 3 is provided to close the top opening and provide further protection. In order to tightly connect and seal the dust cover 3, the first waterproof shell 1 and the second waterproof shell 2, a connecting mechanism consisting of a first connecting strip 4 and a second connecting strip 5 is adopted. This connecting mechanism not only realizes the mechanical connection, but also completes the pressing task of the second seal at the same time. Specifically, the outer side of the second connecting strip 5 is fixedly connected with a plug 604 for positioning and enhancing connection strength, while the interior of the first connecting strip 4 forms a cavity that matches the plug 604. During assembly, the plug 604 is inserted into the cavity, and the first connecting strip 4 and the second connecting strip 5 are threaded together by multiple second bolts 605. The assembled connecting mechanism is clamped between the edge of the dust cover 3 and the top platform of the first waterproof shell 1 and the second waterproof shell 2, applying axial clamping force to them. Along with the above-mentioned pressing action, the second sealing structure in the sealing assembly 9 begins to function. The first sealing gasket 902 is pressed downward by the first connecting strip 4 and fits tightly against the surface of the dust cover 3, while the second sealing gasket 903 is pressed upward by the second connecting strip 5 and fits tightly against the top surfaces of the first waterproof shell 1 and the second waterproof shell 2, thereby forming a tight seal with two channels in the top connection area.

[0025] To achieve the aforementioned detachable fastening and precise positioning, the system also includes the installation structure of the disassembly and assembly component 6, the lamp holder 7, and the positioning structure of the dust cover 3. These components form a specific structural fit and connection relationship with the first waterproof shell 1 and the second waterproof shell 2. These structures will be described in detail below. Please refer to the following carefully. Figure 1 , Figure 3 and Figure 5 The disassembly and assembly component 6 is used to provide the main radial locking force. Its structural details are as follows: the locking block 602, which is fixedly connected to the outer wall of the first waterproof shell 1 and the second waterproof shell 2, has an outer surface that forms an arc surface that matches the inner wall of the fixed shell 601, providing a smooth contact reference for the installation of the fixed shell 601. The fixed shell 601 itself is a shell with a C-shaped cross section along its length. Its open C-shaped structure allows it to be directly snapped into and covered on the outer surface of the locking block 602 from the side. After installation, the first bolt 603 passes through the fixed shell 601 and is screwed into the threaded hole of the locking block 602. By tightening the first bolt 603, a strong positive pressure is generated between the inner wall of the fixed shell 601 and the outer surface of the locking block 602, thereby firmly clamping the first waterproof shell 1 and the second waterproof shell 2 together. This external locking structure ensures the convenience of operation and the reliability of locking. At the same time, please refer to Figure 1 and Figure 5The installation method of the lamp holder 7 within the accommodating space is also precisely designed. On the inner walls of the first waterproof shell 1 and the second waterproof shell 2, respectively, there are locking strips 8 with specific cross-sections fixedly connected along the axial direction. On the outer peripheral wall of the lamp holder 7, there are corresponding slots 10 with shapes and sizes that match the locking strips 8. During the assembly process, the slots 10 of the lamp holder 7 are aligned with the locking strips 8 on the waterproof shell and slide into the socket along the axial direction. This track-type sliding fit structure not only simplifies the installation process of the lamp holder 7, but also ensures the precise positioning of the lamp holder 7 within the accommodating space, preventing it from rotating or shaking. Please refer to further details. Figure 1 and Figure 2 In order to achieve the initial positioning and fit between the dust cover 3 and the top of the housing, the lower edges of the first waterproof housing 1 and the second waterproof housing 2 are integrally formed with downwardly extending insert edges. Correspondingly, an annular slot 11 that matches the insert edge is formed on the top outer wall of the dust cover 3. When the dust cover 3 is placed on the top, its insert edge can be accurately inserted into the slot 11. This insertion relationship provides a reference for the subsequent installation of the first connecting strip 4 and the second connecting strip 5, and initially seals the gap at the top.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, for ease of bulb installation and replacement, please refer to... Figure 5 The lamp holder 7 has a through-hole 12 for mounting a light bulb, which provides a standard mounting interface for the light bulb. As a further optimization of the above-mentioned installation interface, the inner wall of the mounting hole 12 is also provided with a mating structure for fixing the bulb base. This mating structure can be specifically implemented as a thread that matches the bulb base to fix the bulb by means of threaded connection, or it can be implemented as a flexible locking point or locking ring to fix the bulb by means of locking, thereby ensuring that the bulb is firmly connected and has good contact after installation. As a preferred embodiment, in order to ensure that the first connecting strip 4 and the second connecting strip 5 can apply a uniform clamping force to the top sealing structure after they are connected, a plurality of second bolts 605 for locking the two are provided, and these second bolts 605 are evenly distributed along the length direction of the first connecting strip 4. This evenly distributed locking point design avoids the problem of excessive local stress or uneven clamping, thereby significantly improving the reliability of the top seal. As another preferred embodiment, in order to achieve a highly efficient and durable sealing effect, the first sealing gasket 902 and the second sealing gasket 903 in the sealing assembly 9 are preferably made of elastic sealing rings, such as silicone rubber or EPDM rubber. The elastic properties of this material ensure that the sealing ring can undergo elastic deformation after being pressed by the first connecting strip 4 and the second connecting strip 5, thereby fully filling the tiny gaps between the dust cover 3, the first waterproof shell 1 and the second waterproof shell 2, forming a reliable waterproof and dustproof barrier.

[0027] The working principle of this dustproof and waterproof lighting housing is as follows: When the internal bulb needs to be repaired or replaced, the entire outer casing can be easily disassembled. First, the operator loosens and removes multiple second bolts 605 to release the locking state between the first connecting strip 4 and the second connecting strip 5. Then, the first connecting strip 4 and the second connecting strip 5 can be pulled outward. During the pulling process, the insert 604 fixed to the outside of the second connecting strip 5 will disengage from the internal cavity of the first connecting strip 4. At the same time, the first sealing gasket 902 and the second sealing gasket 903, which were originally compressed, will also be relieved of pressure and released from the sealing state. After the connecting mechanism is completely removed, the dust cover 3 is no longer compressed and can be easily removed, allowing its insert edge to disengage from the slot 11. Next, the operator loosens and removes the first bolt 603 on the outside of the fixing shell 601, thereby releasing the radial locking force of the fixing shell 601 on the locking block 602. At this time, the first waterproof shell 1 and the second waterproof shell 2 can be pulled outwards, so that the two are separated along the mating surface. During the separation process, the locking block 602 fixed to the outer wall of the waterproof shell will be removed from the cover of the fixing shell 601, and the locking strip 8 fixed to the inner wall of the waterproof shell will also slide out from the slot 10 of the lamp holder 7. When the waterproof shell is completely separated and removed, the lamp holder 7 and the bulb inside are fully exposed. The maintenance personnel can easily rotate the bulb and unscrew it from the mounting hole 12 in the middle of the lamp holder 7 for replacement or repair. The entire disassembly and assembly process is logically clear and easy to operate. In its assembled state, this invention ensures excellent dustproof and waterproof performance through a double-sealing structure. First, at the mating edge of the first waterproof shell 1 and the second waterproof shell 2, the sealing strip 901 is tightly pressed by the locking force of the disassembly and assembly component 6, forming a reliable first main seal that effectively prevents dust and moisture from intruding from the shell seams. Second, in the top connection area, the first sealing gasket 902 is firmly pressed between the dust cover 3 and the first connecting strip 4 by the fastening force of the first connecting strip 4 and the second connecting strip 5, while the second sealing gasket 903 is firmly pressed between the second connecting strip 5 and the top surfaces of the first waterproof shell 1 and the second waterproof shell 2. These two annular seals together constitute the second layer of protection. This double-sealing design significantly improves the overall dustproof and waterproof performance, ensuring that no impurities or moisture penetrate the connection.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
