Description

Technical Field

[0001] This utility model relates to the field of lighting fixture technology, and in particular to a sealing structure for lighting fixtures. Background Technology

[0002] Lighting fixtures are widely used in various indoor and outdoor environments to provide people with necessary illumination. The housing material, structural form, and requirements of the place of use all affect the performance and durability of the fixtures. In outdoor or special environments, lighting fixtures need to have characteristics such as dustproof, waterproof, and shockproof to ensure long-term stable operation. Therefore, in order to ensure the safety and durability of the fixtures, the design of the sealing structure is a crucial part, which can effectively prevent external pollutants from entering and ensure the normal use of the fixtures under different environmental conditions.

[0003] Existing lighting fixture sealing structures lack quick and convenient lampshade connection and installation methods. The installation of existing lampshades and bases usually involves common threaded connections or external screw connections, which increases the complexity of installation. In addition, special tools are required for screw connections, resulting in more time spent in the installation and disassembly process, reducing efficiency in actual use. Furthermore, although existing sealing structures emphasize sealing performance, they neglect the control of internal air pressure balance while maintaining the seal. Temperature differences or environmental pressure fluctuations often lead to uneven air pressure inside the lampshade, which in turn affects the sealing performance and may even lead to overall structural damage or seal failure.

[0004] Therefore, addressing the problems of existing lighting fixture sealing structures, this utility model employs a rotary locking mechanism. The engagement between the connecting seat and the mounting seat makes the connection between the lampshade and the base more secure, while also enabling quick assembly and disassembly. The lighting fixture is installed via a threaded seat, and a sealing gasket ensures a tight seal. Ventilation holes are provided in the base to balance air pressure and prevent pressure changes caused by temperature differences from affecting the sealing effect. The waterproof plate effectively blocks external water flow, ensuring waterproof and breathable performance. Furthermore, the reinforcing frame and reinforcing ring form a stable support, improving the explosion-proof and durability of the sealing structure, thereby extending its service life. This optimizes the sealing installation structure of the lighting fixture, improving installation convenience and sealing stability. Utility Model Content

[0005] To overcome the shortcomings of a common lighting fixture sealing structure, existing lighting fixture sealing structures lack a quick installation method. They typically use threaded or external screw connections, which increases installation complexity and requires specialized tools, reducing the efficiency of installation and disassembly. At the same time, although existing sealing structures emphasize sealing performance, they fail to effectively control internal air pressure balance. Temperature differences or fluctuations in environmental pressure can lead to uneven air pressure, affecting sealing performance and even causing structural damage or seal failure.

[0006] The technical solution of this utility model is as follows:

[0007] A sealing structure for a lighting fixture includes a lampshade, a mounting base, and a base; a connecting seat is fixedly connected to the bottom of the lampshade, the connecting seat is engaged inside the mounting base, the connecting seat is in close contact with the mounting base near the lampshade, a sealing seat is fixedly connected to the bottom of the mounting base, the base is fixedly connected to the bottom of the sealing seat, the sealing seat is located near the outer side wall of the base, and the base is located away from the lampshade.

[0008] Preferably, the lampshade is made of tempered glass, the connecting seat has a protrusion near the bottom, the mounting seat and the sealing seat are annular structures, the base is a conical structure, and the sealing seat and the base are an integrated structure.

[0009] Preferably, a reinforcing frame is fixedly connected to the top of the connecting base. The reinforcing frame is installed at equal angles on the outer side wall of the lampshade. A reinforcing ring is fixedly connected to the outer side wall of the reinforcing frame. The reinforcing ring is installed at equal intervals on the reinforcing frame at a position away from the lampshade. A connecting ring is fixedly connected to the end of the reinforcing frame away from the connecting base. The connecting ring is fixedly connected to the top of the lampshade.

[0010] Preferably, the top of the mounting base has a slot, which is symmetrically distributed on both sides of the mounting base. The mounting base has an installation ramp fixedly connected inside, which is located near the slot. A button is slidably connected inside the mounting base.

[0011] Preferably, the button is located away from the slot and near the mounting ramp. A stabilizing block is fixedly connected to the bottom of the button, and a return spring is fixedly connected to the bottom of the stabilizing block. The return spring is located away from the button, and the end of the return spring away from the stabilizing block is fixedly connected to the inside of the mounting base.

[0012] Preferably, a sealing gasket is fixedly connected to the top of the base, and the sealing gasket is fixedly connected to the inner side wall of the mounting base and the sealing base. The base has ventilation holes inside.

[0013] Preferably, the vent holes are distributed at equal angles inside the base, the vent holes penetrate the base, a waterproof plate is fixedly connected inside the vent holes, the waterproof plate is located near the outer side wall of the base, and a threaded seat is fixedly connected to the inner side wall of the base.

[0014] The beneficial effects of this utility model are:

[0015] 1. During installation, align the protrusion at the bottom of the connector with the slot so that it fits against the button. Then, press and rotate the connector to allow the bottom protrusion to slide downwards along the installation ramp. Guided by the installation ramp, the connector gradually moves downwards and applies pressure to the button, causing the button and the retaining block to compress downwards synchronously until the connector reaches the designated position. The retaining block fits tightly against the bottom protrusion of the connector, locking the connector and thus completing the quick fixation of the lampshade and ensuring stable installation. During disassembly, rotate the connector in the opposite direction so that the bottom protrusion gradually moves upwards along the installation ramp and gradually releases the pressure on the button. When the connector rotates to the slot position, the return spring pushes the retaining block and the button to automatically reset, thus achieving quick disassembly of the sealing structure while ensuring installation stability and sealing capability.

[0016] 2. When installing the lighting fixture, remove the lampshade. Then, align the threads on the bottom of the lighting fixture with the threaded seat and screw it in to ensure that the bulb and the sealing gasket fit tightly together, thus completing the sealing connection. The vent balances the internal and external air pressure to prevent the sealing effect from being affected by temperature differences. The waterproof plate can block external water flow. The vent adopts an L-shaped channel to ensure air circulation and waterproofing, and ensures stable air pressure, thereby ensuring the stable operation of the lighting fixture and extending its service life.

[0017] 3. After the lighting fixtures are installed, they are located inside the lampshade, which is made of tempered glass to protect the bulbs and improve their explosion-proof performance and durability. The reinforcing frame is connected to the reinforcing ring to form a stable support skeleton, and the lampshade is fixed by the connecting ring to enhance the structural strength and safety, thereby ensuring the stable operation of the lighting fixtures and extending their service life.

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.

[0026] Please see Figures 1-6 This utility model provides a technical solution: a sealing structure for a lighting fixture, including a lampshade 1, a mounting base 3, and a base 5; a connecting seat 2 is fixedly connected to the bottom of the lampshade 1, the connecting seat 2 is engaged with the inside of the mounting base 3, the connecting seat 2 is in close contact with the mounting base 3 near the lampshade 1, a sealing seat 4 is fixedly connected to the bottom of the mounting base 3, and the base 5 is fixedly connected to the bottom of the sealing seat 4, the sealing seat 4 is located near the outer side wall of the base 5, and the base 5 is located away from the lampshade 1.

[0027] The lampshade 1 is made of tempered glass. The connecting seat 2 has a protrusion near the bottom. The mounting seat 3 and the sealing seat 4 are ring-shaped structures. The base 5 is a conical structure. The sealing seat 4 and the base 5 are an integrated structure. The use of tempered glass in the lampshade 1 improves the overall explosion-proof performance. The integrated structure improves the overall sealing performance. The ring structure design makes the overall force more even. The conical structure design further enhances the structural strength and improves the overall structural stability.

[0028] A reinforcing frame 101 is fixedly connected to the top of the connecting base 2. The reinforcing frame 101 is installed at equal angles on the outer side wall of the lampshade 1. A reinforcing ring 102 is fixedly connected to the outer side wall of the reinforcing frame 101. The reinforcing ring 102 is installed at equal intervals on the reinforcing frame 101 away from the lampshade 1. A connecting ring 103 is fixedly connected to the end of the reinforcing frame 101 away from the connecting base 2. The connecting ring 103 is fixedly connected to the top of the lampshade 1. The reinforcing frame 101 and the reinforcing ring 102 form a uniform force support, improve the impact resistance, and prevent the lampshade 1 from loosening or being damaged due to external forces. The connecting ring 103 optimizes the connection and installation, ensuring a tight connection between the reinforcing frame 101 and the lampshade 1 bracket.

[0029] The top of the mounting base 3 is provided with a slot 301, which is symmetrically distributed on both sides of the mounting base 3. The mounting base 3 is fixedly connected to the interior of the mounting base 3, and the mounting ramp 302 is located near the slot 301. The mounting base 3 is slidably connected to the interior of the mounting base 3. The symmetrical distribution of the slots 301 enhances the fixing effect on the connecting base 2. The mounting ramp 302 guides the bottom protrusion of the connecting base 2, so that it gradually presses down or rises during rotation.

[0030] Button 303 is located away from slot 301 and near mounting ramp 302. A stabilizing block 304 is fixedly connected to the bottom of button 303. A return spring 305 is fixedly connected to the bottom of stabilizing block 304. The return spring 305 is located away from button 303. One end of the return spring 305 away from stabilizing block 304 is fixedly connected to the inside of mounting base 3. Button 303 is directly connected to stabilizing block 304 and provides continuous elastic support through return spring 305 to maintain the overall stability of mounting base 3 and prevent loosening due to external vibration.

[0031] A sealing gasket 501 is fixedly connected to the top of the base 5. The sealing gasket 501 is fixedly connected to the inner side wall of the mounting base 3 and the sealing base 4. A vent hole 502 is opened inside the base 5. The sealing gasket 501 ensures the sealing between the lighting fixture and the base 5, effectively preventing external pollutants from entering the interior and improving the overall protection capability of the mechanism. The vent hole 502 balances the internal and external air pressure and prevents changes in internal air pressure caused by temperature differences, thereby affecting the sealing effect.

[0032] Ventilation holes 502 are evenly distributed inside the base 5 and penetrate the base 5. A waterproof plate 503 is fixedly connected inside the ventilation holes 502. The waterproof plate 503 is located near the outer side wall of the base 5. A threaded seat 504 is fixedly connected to the inner side wall of the base 5. The waterproof plate 503 improves the waterproof capability of the mechanism. Combined with the ventilation holes 502, it not only ensures air pressure balance but also effectively blocks the penetration of external moisture, achieving dual protection of sealing and waterproofing.

[0033] Working principle: According to Figures 1 to 3 After the sealing structure completes the installation of the lighting fixture, the lighting fixture is located inside the lampshade 1. Since the lampshade 1 is made of tempered glass, it can effectively protect the bulb and improve the explosion-proof and durability of the overall structure. At the same time, the reinforcing frame 101 is connected to the reinforcing ring 102 to form a stable support frame, and is fixed to the lampshade 1 through the connecting ring 103, further enhancing the structural strength and safety.

[0034] according to Figures 4 to 5When installing the lighting fixture, firstly, rotate the connecting seat 2 in the opposite direction by external force to remove the lampshade 1. Then, align the thread on the bottom of the lighting fixture with the thread seat 504 and screw it into it so that the bulb and the sealing gasket 501 fit tightly together. At this time, the lighting fixture, the sealing seat 4 and the base 5 are sealed together. The vent 502 is used to balance the internal and external air pressure and prevent the air pressure imbalance caused by temperature difference from affecting the sealing effect. The waterproof plate 503 can block the external water flow into the interior of the mechanism. The vent 502 adopts an L-shaped channel design, which not only prevents water flow from entering directly, but also allows air to circulate and ensures stable air pressure.

[0035] according to Figure 6 When installing the lampshade 1 and the base 5, first, install the lighting fixture inside the base 5. Then, align the protrusion at the bottom of the connecting seat 2 with the slot 301 on the mounting seat 3, so that the connecting seat 2 fits against the button 303. At this time, press the connecting seat 2 with external force to push it into the mounting seat 3. At the same time, rotate the connecting seat 2 so that the bottom protrusion slides down along the mounting ramp 302. Under the guidance of the mounting ramp 302, the connecting seat 2 gradually moves down and applies pressure to the button 303, so that the button 303 and the stabilizing block 304 are compressed downward synchronously until the connecting seat 2 reaches the designated position, the button 303 is completely inserted into the mounting seat 3, and the stabilizing block 304 fits tightly against the bottom protrusion of the connecting seat 2, thereby completing the quick fixing of the lampshade 1 and ensuring stable installation.

[0036] according to Figure 6 When it is necessary to disassemble the lampshade 1 and the base 5, firstly, the connecting seat 2 is rotated in the opposite direction by external force, so that the bottom protrusion gradually moves upward along the mounting slope 302. As the rotation proceeds, the connecting seat 2 gradually releases the pressure on the button 303. When the connecting seat 2 rotates to the slot 301 position, the connecting seat 2 completely stops applying pressure to the button 303. At this time, under the elastic force of the return spring 305, the stabilizing block 304 and the button 303 automatically reset, thereby realizing the quick disassembly of the sealing structure while ensuring installation stability.

[0037] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
