Description
Double-ended UV lamp holder fixing structure Technical Field
[0001] This utility model relates to the field of UV lamp technology, and in particular to a UV lamp holder fixing structure with double-ended leads. Background Technology
[0002] In water treatment, ultraviolet (UV) disinfection is a commonly used and effective method. As the core component of UV disinfection equipment, the fixed structure of the lamp head in a double-ended UV lamp has a significant impact on the lamp's stability, lifespan, and disinfection effect.
[0003] Existing methods for fixing the lamp heads of double-ended UV lamps have some shortcomings. For example, a non-slip UV lamp disclosed in CN218730796U involves sliding a slider towards the center on a sliding rod, causing a slip ring to slide towards the center on the lamp head. At this time, the spring is compressed and undergoes elastic deformation. Then, the plug is inserted into the conductive sleeve, and the slip ring is released. The spring returns to its original shape and causes the slip ring to return to its original position. At this time, the locking strip can be inserted into the slot to fix the UV lamp to the lamp holder. Although this helps to solve the problem of insecure installation and connection of traditional UV lamps, it is difficult to operate the lamp head directly in the narrow sleeve structure. It is difficult to ensure proper installation, which can easily cause the lamp to shake during operation, affecting the uniform irradiation of ultraviolet rays. Installation and disassembly are not convenient enough, which also increases the difficulty and cost of equipment maintenance. Furthermore, it is difficult to ensure that the lamp is in the center of the quartz sleeve, which will affect the propagation efficiency of ultraviolet rays and the disinfection effect. Summary of the Invention
[0004] The purpose of this utility model is to solve the problem of insufficient stability in the fixing of UV lamp heads in the existing technology, which affects the safety of use, and proposes a UV lamp head fixing structure with double-ended wires.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] The UV lamp holder fixing structure with double-ended output includes a quartz glass sleeve, a UV lamp body and two aluminum alloy lamp holders. The UV lamp body has connecting parts at both ends for fixing the aluminum alloy lamp holders, and the two aluminum alloy lamp holders have locking parts for fixing the aluminum alloy lamp holders inside the two ends of the quartz glass sleeve.
[0007] Preferably, the UV lamp tube body is concentrically fitted inside a quartz glass sleeve by two aluminum alloy lamp heads.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Referring to Figures 1-6, the dual-ended UV lamp holder fixing structure includes a quartz glass sleeve 1, a UV lamp body 2, and two aluminum alloy lamp holders 3. It should be noted that by first fixing the aluminum alloy lamp holders 3 to both ends of the UV lamp body 2 to form a lamp holder module, and then fixing the two aluminum alloy lamp holders 3 to the quartz glass sleeve 1, the UV lamp body 2 is concentrically fitted into the quartz glass sleeve 1 through the two aluminum alloy lamp holders 3. As long as the two aluminum alloy lamp holders 3 are concentrically aligned with the quartz glass sleeve 1, the UV lamp body 2 can be centrally positioned within the quartz glass sleeve 1, ensuring that ultraviolet light spreads evenly from the UV lamp body 2 to all sides, improving the utilization efficiency and treatment effect of ultraviolet light. Simultaneously, the quartz glass sleeve 1 provides reliable protection for the UV lamp body 2, and its good light transmittance ensures the effective propagation of ultraviolet light.
[0024] To better achieve the above objectives, the following improvements are needed:
[0025] First, the aluminum alloy lamp holder 3 includes a main tube 31, which is cylindrical in shape to facilitate the setting of an outer circular groove 5 on the outer surface. An internal threaded connector 32 is integrally connected to the inner end of the main tube 31. A first countersunk hole 33 for installing a locking screw is opened in the main tube 31. By setting the internal threaded connector 32 and the first countersunk hole 33, the connecting end 41 that is magnetically connected to the UV lamp tube body 2 is fixedly connected to the aluminum alloy lamp holder 3, so as to prevent the internal threaded connector 32 and the external threaded connector 43 from gradually loosening due to vibration.
[0026] Secondly, the outer wall of the main tube 31 is provided with an outer circular groove 5 for the built-in locking part 8, and the inner wall of the quartz glass sleeve 1 is provided with an inner circular groove 6 that is concentrically corresponding to the outer circular groove 5. The quartz glass sleeve 1 is provided with a second countersunk hole 7 that connects to the inner circular groove 6 and is used to insert the pin. By setting the corresponding outer circular groove 5 and inner circular groove 6, the locking part 8 installed in the outer circular groove 5 can be correspondingly snapped into the inner circular groove 6, thereby realizing the assembly and connection of the aluminum alloy lamp holder 3 and the quartz glass sleeve 1.
[0027] The following implementation measures will be further adopted:
[0028] First, the UV lamp tube body 2 has connecting parts 4 at both ends for fixing and connecting the aluminum alloy lamp head 3. The connecting part 4 includes a connecting end 41 that is magnetically connected to the end of the UV lamp tube body 2. An extension rod 42 that movably passes through the aluminum alloy lamp head 3 is integrally connected to the connecting end 41. An external threaded connector 43 corresponding to the internal threaded connector 32 is fixedly fitted on the extension rod 42. A sealing sleeve 44 that is movably fitted in the main tube 31 is integrally connected to the external threaded connector 43. A locking port 45 corresponding to the first countersunk hole 33 is opened on the sealing sleeve 44. It should be noted that when the internal threaded connector 32 and the external threaded connector 43 are threadedly connected and stable, the first countersunk hole 33 corresponds to the locking port 45. At this time, tightening the locking screw helps to further strengthen the connection strength between the main tube 31 and the sealing sleeve 44 and prevent the internal threaded connector 32 and the external threaded connector 43 from loosening.
[0029] Second, the two aluminum alloy lamp holders 3 are provided with locking parts 8 for fixing the aluminum alloy lamp holders 3 inside the two ends of the quartz glass sleeve 1. The locking part 8 includes a strong coil spring 81 fixedly fitted in the outer circular groove 5. Four circumferentially equidistant limiting arc plates 82 are fixedly connected to the strong coil spring 81. Each of the four limiting arc plates 82 has a receiving arc cavity 83 at both ends. A telescopic crank rod 84 that is slidably fitted in the receiving arc cavity 83 is connected between each two adjacent limiting arc plates 82. It should be noted that when it is necessary to remove the locking part 8 from the inner circular groove 6, the pin is squeezed into the inner circular groove 6 through the second countersunk hole 7. The limiting arc plate 82 is subjected to force and moves along the telescopic crank rod 84 to contract, causing the strong coil spring 81 to contract, so that the limiting arc plate 82 is disengaged from the inner circular groove 6, thereby disconnecting the locking part 8 from the quartz glass sleeve 1.
[0030] The powerful coil spring 81 undergoes radial elastic deformation, and through uniform rebound force across the entire area, it automatically centers and aligns the lamp head module inside the quartz glass sleeve 1. The connection and cooperation between the limiting arc plate 82 and the quartz glass sleeve 1 ensures consistent pressure at each contact point, avoiding localized overheating or mechanical stress concentration caused by the eccentricity of the UV lamp body 2. The UV lamp body 2 is concentrically fitted inside the quartz glass sleeve 1 by two aluminum alloy lamp heads 3, achieving the center positioning of the UV lamp body 2 within the quartz glass sleeve 1. This ensures that ultraviolet light spreads evenly from the UV lamp body 2 to all sides, improving the utilization efficiency and treatment effect of ultraviolet light.
[0031] It should be noted that the specific models and specifications of the quartz glass sleeve 1, UV lamp body 2, and aluminum alloy lamp holder 3 need to be selected and determined according to the actual specifications of the device. The UV lamp body 2 is preferably of model AL6061-T6, with a hard anodized surface treatment (film thickness 20-25μm), which combines lightweight, resistance to chloride ion corrosion and high thermal conductivity. The hard anodized surface is resistant to long-term UV radiation. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.
[0032] The functional principle of this utility model can be explained through the following operation methods:
[0033] Magnetize the connecting end 41 onto the end of the UV lamp tube body 2, mount the aluminum alloy lamp head 3 onto the extension rod 42 and push it spirally so that the external threaded connector 43 and the internal threaded connector 32 are threadedly connected. Tighten the locking screw after the corresponding locking port 45 and the first countersunk hole 33.
[0034] Pressing the limiting arc plate 82 inward causes the high-strength coil spring 81 to retract, ensuring that the high-strength coil spring 81 can freely extend and retract within the outer circular groove 5 without twisting or deformation. During installation, care should be taken to keep the high-strength coil spring 81 clean to prevent impurities from entering the outer circular groove 5 and affecting its elastic performance. The fixedly connected UV lamp tube body 2 and aluminum alloy lamp head 3 are fitted into the quartz glass sleeve 1 until the limiting arc plates 82 in the two sets of locking parts 8 correspond to the positions of the inner circular groove 6. Under the tension of the high-strength coil spring 81, the limiting arc plates 82 open radially and snap into the inner circular groove 6.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
