Description

Technical Field

[0001] This utility model relates to the field of LED lighting equipment technology, and in particular to an inner frame for LED lights. Background Technology

[0002] LED lights, due to their energy-saving and long lifespan characteristics, have been widely used in various scenarios. Their core structure includes the lamp holder, lamp cover, lamp core, filament, and inner frame. As a key support component, the inner frame needs to fix and protect core components such as the lamp core, battery cell, and motherboard. Its structural stability and sealing directly affect the performance and lifespan of the LED light.

[0003] However, existing technologies, such as Chinese Publication No. CN222798722U, describe an inner frame for LED lamps, applicable to structures of lamp heads, lamp covers, lamp cores, and filaments. This includes a support assembly for installing and fixing the lamp core. The support assembly comprises a first support member and a second support member, forming a hollow assembly with an internal cavity. The first and second support members are interlocked. Through the combined structure of the first and second support members, the internal components can be pre-fixed via the internal cavity and the formed groove during installation. Individual fixing effectively secures and seals the internal components, ensuring sealing and safety. Furthermore, its modular structure reduces the processing cost and difficulty of traditional integrated structures. The annular protrusions on the outer surface tightly engage with the lamp head, improving the fixing effect between the assembly, the lamp head, and the internal components.

[0004] However, during use, it can be observed that the support assembly of this device consists of a hollow assembly composed of a first support member and a second support member, which is fixed by a "clamping post + slot" connection. The bottom surface of the assembly has a sealing cover, which is connected by a "slot" type connection to seal and protect the internal components. However, the first and second support members are only mechanically fixed by the "clamping post + slot" connection, without auxiliary locking or anti-loosening structures. The fastening force at the connection relies on the frictional force generated by the elastic deformation of the plastic support member, without additional mechanical support. When the LED light is working, the lamp core, battery cell, and motherboard will generate heat, causing the temperature of the support member to rise. The plastic parts are affected by thermal expansion and contraction, and long-term hot and cold cycles will widen their mating gaps, reduce the friction at the connection, and cause the support member to loosen. Furthermore, the sealing cover is only connected to the bottom surface of the assembly by a "slot" type connection, without a waterproof and moisture-proof structure. In a humid environment, moisture can easily seep in through the gaps, accelerating the aging of components and shortening the lifespan of the LED light. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art where the inner frame support components are prone to loosening and misalignment, and the sealing cover is prone to water leakage and detachment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an inner frame for LED lamps, comprising: a lampshade; an anti-loosening lock accessory disposed inside the lampshade, the outer periphery of which abuts against the inner sidewall of the lampshade; a sealing cover installed at the inner bottom of the anti-loosening lock accessory; and a sealing anti-detachment component disposed at the edge of the sealing cover and at the corresponding position of the anti-loosening lock accessory, which can restrict the relative movement between the sealing cover and the anti-loosening lock accessory.

[0007] The technical effects of adopting the above-mentioned further solutions are as follows: the inner frame of the LED light uses a multi-layer design to solve the problem of loosening and misalignment of the support components, ensuring the long-term stability of the inner frame structure and reducing failures; the sealing anti-detachment component achieves multi-point fixation and double sealing of the sealing cover, preventing water seepage and detachment, protecting internal components, and extending the service life of the LED light.

[0008] In a preferred embodiment, the anti-loosening lock accessory includes: a first support member installed inside the lampshade; and a second support member symmetrically arranged on one side of the first support member; wherein the splicing surfaces of the first support member and the second support member are evenly distributed, and the two form a hollow structure assembly.

[0009] The technical effect of adopting the above-mentioned further solution is as follows: In the anti-loosening locking accessory, the first support component is installed inside the lampshade, and the second support component is symmetrically arranged on one side thereof. The splicing surfaces of the two are evenly distributed and form a hollow assembly. This structure allows the support components to be subjected to balanced forces, effectively preventing loosening and misalignment, providing a stable foundation for the internal frame, reducing failures caused by support problems, and ensuring the stable operation of the internal frame.

[0010] In a preferred embodiment, the anti-loosening lock accessory further includes: a connecting block riveted to the left and right sides of the splicing surface of the first support member; and a limiting guide rail riveted to the left and right sides of the splicing surface of the second support member; wherein the connecting block and the limiting guide rail cooperate with each other.

[0011] The technical advantage of adopting the above-mentioned further solution is that the connecting blocks are riveted to both sides of the splicing surface of the first support member, and the limiting guide rails are riveted to the corresponding positions of the second support member, with the two cooperating with each other. This design further strengthens the connection of the support components, limits relative displacement, reduces the risk of loosening, provides double protection for the stability of the internal frame, and improves the overall structural reliability.

[0012] In a preferred embodiment, the anti-loosening lock accessory further includes: a mounting hole, which is longitudinally disposed in the two connecting blocks; and a limiting rod, which is movably disposed in the middle of the two mounting holes and the limiting guide rail, and can limit the relative movement of the connecting blocks and the limiting guide rail; wherein, the bottom of the limiting guide rail is provided with a limiting hole, and the bottom end of the limiting rod extends into the limiting hole.

[0013] The technical advantage of adopting the above-mentioned further solution is that the mounting hole extends longitudinally through the two connecting blocks, and the limiting rod is movably inserted into the middle of the mounting hole and the limiting guide rail, with its bottom end extending to the limiting hole at the bottom of the limiting guide rail. This structure further restricts the relative movement of the connecting blocks and the limiting guide rail, significantly reducing the risk of loosening and building a solid anti-loosening defense for the internal frame support components.

[0014] In a preferred embodiment, the sealing and anti-detachment component includes: a shock-absorbing frame installed below the sealing cover; and a waterproof sealing gasket disposed in the shock-absorbing frame; wherein the upper end face of the shock-absorbing frame abuts against the lower end face of the sealing cover.

[0015] The technical advantage of adopting the above-mentioned further solution is that the shock-absorbing frame in the sealing and anti-detachment component is installed below the sealing cover, with its upper end face abutting against the lower end face of the sealing cover, and the waterproof sealing gasket is placed inside the shock-absorbing frame. This structure can buffer the impact of external vibration on the sealing cover, while using the waterproof sealing gasket to block water vapor, reducing the risk of sealing cover displacement and water leakage, and ensuring the sealing performance of the inner frame.

[0016] In a preferred embodiment, the sealing anti-detachment component further includes: multiple sets of locking screws, evenly distributed in a circular array around the periphery of the sealing cover; multiple sets of first locking holes, evenly distributed around the periphery of the sealing cover; and multiple sets of second locking holes, evenly distributed around the periphery of the first and second supports; wherein the locking screws sequentially pass through and connect the second and first locking holes, and the locking screws are Phillips head countersunk screws to avoid the screw head protruding and affecting...

[0017] The technical advantages of the above-mentioned further solution are as follows: multiple sets of locking screws for the sealing and anti-detachment components are distributed in a circular array around the periphery of the sealing cover, corresponding to the first locking hole of the sealing cover and the second locking hole of the support component, with the screws passing through both holes sequentially. The cross-groove countersunk head design avoids interference from the protruding head, while the multi-point uniform fixing enhances the stability of the sealing cover, further reducing the risk of detachment.

[0018] In a preferred embodiment, the anti-loosening lock accessory further includes a pull ring, welded to the top of the limiting rod. This facilitates pulling out the limiting rod to release the lock.

[0019] The technical effect of adopting the above-mentioned further solution is that when it is necessary to release the lock, the operator can directly pull the pull ring to easily pull the limit rod out from the mounting hole and the limit hole without the need for additional tools, which greatly improves the efficiency of disassembly and maintenance, while ensuring the convenience and safety of operation.

[0020] In a preferred embodiment, the sealing and anti-detachment component further includes a waterproof sealing ring disposed at the contact point between the sealing cap and the bottom surfaces of the first and second supports; wherein the waterproof sealing ring is an annular structure, its material is heat-resistant silicone, and its cross-sectional dimensions are adapted to the mating clearance between the sealing cap and the bottom surfaces of the first and second supports.

[0021] The technical advantages of adopting the above-mentioned further solution are as follows: The annular waterproof sealing ring of the sealing and anti-detachment component is located at the contact point between the sealing cover and the bottom surface of the support component. The temperature-resistant silicone material is adapted to the working temperature difference of the LED light. Its cross-sectional dimensions and fitting clearance are precisely matched, which can tightly fill the gaps, effectively prevent external moisture from entering the inner frame, enhance the sealing performance, protect the internal components, and extend the service life of the device.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] This utility model features a multi-layered anti-loosening locking design. First, the first and second support components achieve initial positioning through a mating structure of "connecting blocks and limiting guide rails." The evenly distributed joint surfaces ensure balanced force, preventing early loosening due to uneven local stress. Second, the limiting rod passes through the mounting hole of the connecting block and extends into the limiting hole of the limiting guide rail, forming a dual limiting mechanism of "mating and pinning." Even under long-term vibration, this effectively restricts relative movement between the support components. Simultaneously, the welding and fixing of the pull ring and the limiting rod ensures the integrity of the limiting structure and prevents support failure due to component detachment. Compared to existing technologies, this device offers tighter connection of support components and more reliable limiting, maintaining the stability of the inner frame structure over a long period and reducing malfunctions caused by loosening or misalignment.

[0024] This invention features a multi-dimensional sealing and anti-loosening design. For fixation, multiple sets of countersunk head screws are arranged in a ring array, sequentially penetrating the second and first locking holes, ensuring uniform fixation of the sealing cover and anti-loosening accessories at multiple points, preventing the sealing cover from falling off due to localized loosening. The countersunk design also prevents structural interference caused by protruding screw heads, further enhancing stability. For sealing, the shock-absorbing frame beneath the sealing cover fits tightly with the waterproof sealing gasket, buffering external impacts and blocking some moisture. Simultaneously, the annular heat-resistant silicone waterproof sealing ring at the contact point between the sealing cover and the bottom surface of the support component has a precisely matched cross-sectional size and fitting clearance, completely filling the gap and forming a double sealing barrier. Even in humid or temperature-sensitive environments, it effectively prevents moisture intrusion. Furthermore, the shock-absorbing frame's support for the sealing cover reduces displacement caused by vibration, indirectly improving the sealing effect. Compared to existing technologies, this device provides a more secure and comprehensive sealing of the sealing cover, significantly reducing the risk of water leakage and extending the service life of internal components.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0033] Example 1:

[0034] Please see Figures 1-5 This embodiment provides an inner frame for LED lights with anti-loosening locking function, and its specific concept is as follows:

[0035] An inner frame for LED lights includes a lampshade 1, and the inner frame for LED lights also includes an anti-loosening lock accessory.

[0036] Among them, the lampshade 1 serves as the basic load-bearing structure, and its interior is equipped with anti-loosening locking accessories that can ensure the stable assembly of the internal structure of the lampshade 1.

[0037] As examples, in this embodiment, the anti-loosening lock accessory includes: a first support member 2, a second support member 3, a connecting block 4, a limiting guide rail 5, a limiting rod 6, a limiting hole 7, a pull ring 8, and a mounting hole 13.

[0038] The anti-loosening lock accessory body, consisting of the first support member 2 and the second support member 3, is installed inside the lampshade 1.

[0039] It should be noted that the second support member 3 is arranged symmetrically on one side of the first support member 2, and the splicing surfaces of the two are evenly distributed, forming a hollow structure assembly together, providing space for the installation of subsequent components.

[0040] Connecting blocks 4 are fixed on the left and right sides of the splicing surface of the first support member 2 by riveting.

[0041] In addition, the left and right sides of the splicing surface of the second support member 3 are also equipped with limit guide rails 5 using a riveting process.

[0042] It should be noted that the connecting block 4 and the limiting guide rail 5 can be interlocked to achieve the initial positioning of the first support 2 and the second support 3.

[0043] In addition, to further restrict the relative movement between the two, mounting holes 13 are made longitudinally through the two connecting blocks 4.

[0044] The limiting rod 6 is movably inserted through the middle of the two mounting holes 13 and the limiting guide rail 5.

[0045] In addition, a limiting hole 7 is machined at the bottom of the limiting guide rail 5.

[0046] It should be noted that the bottom end of the limiting rod 6 can extend into the limiting hole 7, forming a double limiting structure.

[0047] In addition, a pull ring 8 is welded to the top of the limit rod 6, which makes it easy for the operator to pull the limit rod 6 to release the locking state.

[0048] In this embodiment, the initial positioning of the "connecting block 4 and limiting guide rail 5" and the secondary locking of the "limiting rod 6 and limiting hole 7" effectively prevent relative displacement between the first support member 2 and the second support member 3 during use, ensuring the stability of the overall structure of the anti-loosening lock accessory; the setting of the pull ring 8 improves the convenience of disassembly and assembly, ensuring both the firmness of assembly and the efficiency of later maintenance.

[0049] Example 2:

[0050] Please see Figures 1-5 Based on Example 1, this example provides an inner frame for LED lights with a sealing and anti-detachment function, the specific idea of ​​which is as follows:

[0051] The inner frame for this LED light also includes: a sealing cover 9 and a sealing anti-detachment component.

[0052] The sealing and anti-detachment component is installed at the bottom of the sealing cover 9.

[0053] As examples, in this embodiment, the sealing anti-detachment component includes: a first locking hole 10, a second locking hole 12, a shock absorber 14, a waterproof sealing gasket 15, multiple sets of locking screws 11, and a waterproof sealing ring.

[0054] The shock absorber 14 is installed below the sealing cover 9.

[0055] It should be noted that the upper end face of the shock absorber 14 is in close contact with the lower end face of the sealing cover 9.

[0056] In addition, the waterproof sealing gasket 15 is embedded inside the shock absorber frame 14.

[0057] Multiple sets of first locking holes 10 are evenly opened around the periphery of the sealing cover 9.

[0058] In addition, multiple sets of second locking holes 12 are also evenly opened on the periphery of the first support member 2 and the second support member 3.

[0059] It should be noted that the locking screw 11 passes through the second locking hole 12 and the first locking hole 10 in sequence to fix the sealing cover 9 and the anti-loosening lock accessory. The locking screw 11 adopts a cross-slot countersunk head structure to avoid the head protruding and causing interference.

[0060] In addition, a waterproof sealing ring with an annular structure is provided at the contact point between the sealing cover 9 and the bottom surfaces of the first support member 2 and the second support member 3.

[0061] It should be noted that the waterproof sealing ring is made of heat-resistant silicone, and its cross-sectional dimensions are perfectly matched with the fit clearance between the sealing cap 9 and the bottom surface of the support.

[0062] In this embodiment, the shock-absorbing frame 14 and the waterproof sealing gasket 15 work together to buffer the impact of external vibrations on the sealing cover 9; the countersunk design of the locking screw 11 and the even distribution of multiple sets of holes ensure that the sealing cover 9 is firmly fixed without any protrusion interference; the waterproof sealing ring made of heat-resistant silicone material and the waterproof sealing gasket 15 form a double seal, which can not only prevent external moisture from entering the inner frame, but also adapt to the temperature changes when the LED light is working, thereby improving the waterproof performance and service life of the inner frame.

[0063] Working Principle: This device is an inner frame for LED lights. In use, the second support member 3 is symmetrically placed on one side of the first support member 2, aligning their evenly distributed splicing surfaces to initially assemble a hollow assembly. Next, connecting blocks 4 are fixed to the left and right sides of the splicing surface of the first support member 2 using a riveting process. Limiting guide rails 5 are installed on the left and right sides of the splicing surface of the second support member 3, allowing the connecting blocks 4 and the limiting guide rails 5 to engage, completing the initial positioning of the first support member 2 and the second support member 3. Then, the limiting rod 6 is inserted through the top of the mounting holes 13 of the two connecting blocks 4, passing through the mounting holes 13 and the middle of the limiting guide rails 5, until the bottom end of the limiting rod 6 extends into the limiting hole 7 at the bottom of the limiting guide rail 5, forming a double limit. Finally, it is confirmed that the pull ring 8 has been welded to the top of the limiting rod 6, completing the assembly of the anti-loosening locking accessory.

[0064] Next, place the assembled anti-loosening lock accessory into the lampshade 1, and adjust its position so that the outer periphery of the anti-loosening lock accessory is in close contact with the inner wall of the lampshade 1, ensuring that the anti-loosening lock accessory is placed stably inside the lampshade 1 without significant shaking.

[0065] Next, install the shock absorber 14 below the sealing cover 9, ensuring that the upper surface of the shock absorber 14 is in close contact with the lower surface of the sealing cover 9. Then, embed the waterproof sealing gasket 15 inside the shock absorber 14. Next, place an annular heat-resistant silicone waterproof sealing ring at the contact point between the sealing cover 9 and the bottom surfaces of the first support member 2 and the second support member 3, ensuring that the cross-section of the sealing ring matches the mating clearance. Then, align the sealing cover 9 with the bottom of the anti-loosening lock accessory, aligning the first locking hole 10 around the sealing cover 9 with the second locking holes 12 around the first support member 2 and the second support member 3. Finally, pass multiple sets of cross-slot countersunk locking screws 11 through the second locking holes 12 and the first locking holes 10 and tighten them to complete the fixing of the sealing cover 9.

[0066] If maintenance is required later, first unscrew all locking screws 11, remove the sealing cover 9 and related sealing anti-detachment parts. Then pull the pull ring 8 upward to pull the limit rod 6 out from the limit hole 7 and the mounting hole 13. After releasing the limit, separate the connecting block 4 from the limit guide rail 5, and then disassemble the first support 2 and the second support 3 for internal component inspection or replacement.
