Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures, and in particular to a retractable lighting fixture. Background Technology

[0002] Existing lighting fixtures are generally fixed in structure. This design is traditional and outdated, with the lamp housing and lampshade positioned in a fixed manner. The distance between the light source and the lampshade cannot be adjusted, resulting in a limited range of light output that cannot adapt to different scenarios and fails to meet the varying brightness and range requirements of different users. From a packaging and portability perspective, fixed lighting fixtures require packaging designed for their fully unfolded dimensions, leading to large packaging sizes and high warehousing and transportation costs. Furthermore, the fixed structure cannot be retracted, requiring significant space for outdoor transport and hindering portability, making it unsuitable for mobile scenarios such as camping and emergency lighting, thus limiting its applicability. Additionally, the few existing attempts at retractable lighting fixtures suffer from complex structural designs, cumbersome retraction operations, and unscientific design flaws, failing to truly address the core pain points of fixed lighting fixtures.

[0003] Therefore, how to achieve a retractable lamp with a scientifically sound and simple design, a clever and simple structure that allows the lamp to have a "contraction-extension" dual state through a movable interlocking structure, fewer parts, simple and efficient production and assembly, effectively reducing production costs, reducing packaging size, reducing warehousing and transportation costs, and strong portability, while allowing for adjustment of the distance between the light source structure and the lampshade during use to flexibly change the brightness and range of light output, and with a wide range of applications, is a technical problem that the industry urgently needs to solve. Summary of the Invention

[0004] The main purpose of this utility model is to provide a retractable lamp, which aims to achieve a scientific and reasonable design, a clever and simple structure, and a dual "contraction-extension" state through a movable locking structure. It has fewer parts, is easy and efficient to produce and assemble, effectively reduces production costs, reduces packaging size, reduces warehousing and transportation costs, and is highly portable. When in use, the distance between the light source structure and the lampshade can be adjusted to flexibly change the brightness and range of light output. It has a wide range of applications and also has the advantages of excellent heat dissipation.

[0005] This utility model proposes a retractable lamp, including a lampshade, a lamp housing, a lamp head located at the bottom of the lamp housing, a middle ring connecting the lampshade and the lamp housing, and a light source structure located inside the lamp housing; the middle ring is fitted over the lamp housing and is movably connected by a movable locking structure, thereby allowing the lamp housing to retract and move; the lamp housing is provided with several guide grooves, and a locking platform is provided in the guide grooves; the inner sidewall of the middle ring is provided with several guide posts that can move along the guide grooves and movably engage with the locking platforms, and the guide posts include a guide post part and an upward-facing part located at the top of the guide post part. The protruding arc-shaped locking point can be pushed by external force to engage or disengage with the locking platform. The guide groove, locking platform, and guide locking post form a movable engaging structure. When the middle ring is pushed from the bottom of the lamp housing upwards to the top of the lamp housing, the guide locking post moves upward along the guide groove until the arc-shaped locking point engages with the locking platform, thus completing the extension operation of the lamp housing. When the lamp housing is pushed in the opposite direction, the arc-shaped locking point disengages from the locking platform, thus allowing the lamp housing to retract.

[0021] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0023] Reference Figures 1 to 10 This invention proposes an embodiment of a retractable lamp, comprising a lampshade 101, a lamp housing 102, a lamp head (not shown in the figures) disposed at the bottom of the lamp housing 102, a central ring 103 connecting the lampshade 101 and the lamp housing 102, and a light source structure (not shown in the figures) disposed within the lamp housing 102.

[0024] The central ring 103 is fitted outside the lamp housing 102 and is movably connected through a movable locking structure, thereby allowing the lamp housing 102 to be telescopically moved.

[0025] The lamp housing 102 is provided with several guide grooves 104, and a locking platform 105 is provided in the guide groove 104. The inner side wall of the middle ring 103 is provided with several guide pins that can move along the guide grooves 104 and engage with the locking platform 105. The guide pins include guide pin parts 106 and inwardly protruding arc-shaped locking points 107 located at the top of the guide pin parts 106. The arc-shaped locking points 107 can be engaged or disengaged from the locking platform 105 by external force. The guide grooves 104, the locking platforms 105 and the guide pins form a movable engaging structure.

[0026] When the middle ring 103 is slipped from the bottom of the lamp housing 102 upwards until it reaches the top of the lamp housing 102, the guide pin moves upwards along the guide groove 104 until the arc-shaped locking point 107 engages with the locking platform 105, thus completing the extension operation of the lamp housing 102. When the lamp housing 102 is pushed in the opposite direction, the arc-shaped locking point 107 disengages from the locking platform 105, thereby allowing the lamp housing 102 to retract.

[0027] The top of the lamp housing 102 is provided with a limiting step 108, and the lower end of the middle ring 103 is provided with a limiting ring 109 that abuts against the limiting step 108 for limiting.

[0028] The inner wall of the central ring 103 is also provided with several guide strips 110 that can move along the guide groove 104. During assembly, they can be quickly guided and positioned, and they also play a role in guiding and stabilizing during the telescopic movement of the lamp housing 102.

[0029] The middle ring 103 and the lampshade 101 are connected and fixed by a snap-fit ​​structure. The lampshade 101 has several slots 111, and the middle ring 103 has several corresponding locking blocks 112. The locking blocks 112 snap into the corresponding slots 111, thus securing the middle ring 103 and the lampshade 101 together. The snap-fit ​​connection enables tool-free and quick assembly of the lampshade 101 and the middle ring 103.

[0030] The lamp housing 102 and the middle ring 103 are made of materials with a certain degree of elasticity, such as plastic or elastic metal. Utilizing the elasticity of the materials, the arc-shaped locking point 107 of the guide pin can elastically pass over the locking platform 105, and the locking block 112 of the middle ring 103 can elastically snap into the locking slot 111. After deformation, it automatically resets, which simplifies assembly and adjustment, and ensures the reliability of the connection structure during long-term use, avoiding the defects of rigid materials being prone to jamming and breakage.

[0031] When assembling the lampshade 101, lamp housing 102, and middle ring 103, first slip the middle ring 103 over the lamp housing 102 from the bottom upwards until it is completely over the lamp housing 102. Then, snap the lampshade 101 and the middle ring 103 together. The extension and retraction process is as follows: When extension is required, slip the middle ring 103 over the lamp housing 102 from the bottom upwards until it reaches the top of the lamp housing 102. The guide pin moves upwards along the guide groove 104 until the arc-shaped locking point 107 engages with the locking platform 105, thus completing the extension operation of the lamp housing 102, and the lamp housing 102 is fully extended. When retraction is required, push the lamp housing 102 in the opposite direction to disengage the arc-shaped locking point 107 from the locking platform 105, and the lamp housing 102 becomes movable and can be retracted.

[0032] The light source structure includes an LED light source component and a driving device electrically connected to the LED light source component.

[0033] The lamp housing 102 is provided with several hollow heat dissipation strip holes 113. The hollow heat dissipation strip holes 113 ensure heat dissipation efficiency while not hindering the expansion and contraction of the lamp housing 102, avoiding the expansion and contraction jamming caused by the heat dissipation structure, ensuring that the expansion and contraction functions work together with the heat dissipation function, and extending the service life compared with fixed lamps.

[0034] The telescopic design of this lamp is scientifically sound and ingeniously simple in structure. Through a movable locking mechanism, the lamp exhibits a dual "retracted-extended" state: the lamp housing 102 is retracted during packaging and transportation, and extended only when in use. This reduces packaging size and lowers warehousing and transportation costs, while also offering superior portability. When retracted, its compact size allows users to easily carry it in their pockets outdoors, significantly outperforming fixed lamps. Furthermore, the lamp has fewer components, simplifying and facilitating efficient production and assembly, effectively reducing production costs. In use, extending the lamp housing 102 changes the distance between the light source structure and the lampshade 101, thereby adjusting the light output. The brightness and range of the light output can be adjusted, making it suitable for various scenarios and with a wide range of applications. It overcomes the shortcomings of fixed lamps, such as high packaging and transportation costs, poor portability, and inability to adjust light output, achieving a balance between cost reduction, portability, and optimized functionality through an innovative telescopic structure.

[0035] This utility model realizes a retractable lamp with a scientific and reasonable design, ingenious and simple structure, and a movable locking structure that allows the lamp to have a "contraction-extension" dual state. It has fewer parts, is easy and efficient to produce and assemble, effectively reduces production costs, reduces packaging size, reduces warehousing and transportation costs, and is highly portable. When in use, the distance between the light source structure and the lampshade 101 can be adjusted to flexibly change the brightness and range of light output. It has a wide range of applications and also has the advantages of excellent heat dissipation.

[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
