Description

Technical Field

[0001] This utility model relates to a lamp holder, and more particularly to a lamp holder for an ultraviolet lamp. Background Technology

[0002] Currently, ultraviolet water treatment lamps mainly consist of a lamp tube with a quartz sleeve surrounding it, preventing the lamp tube from directly contacting the water. The lamp tube's tail is connected to a cable, which secures it, but the lamp head is suspended in the air. This structure makes it susceptible to damage during transport due to vibrations; the lamp tube and quartz sleeve may collide, causing damage to either. Therefore, most products have the lamp tube installed on-site after the equipment arrives. While this avoids breakage during transport, vibrations during pipeline use can still cause the lamp tube to resonate, damaging the filament and reducing its lifespan.

[0003] Chinese patent application CN101752190A discloses an invention patent entitled "An Ultraviolet Lamp and Sleeve Assembly," which includes an ultraviolet lamp and a sleeve with a gap between them. The ultraviolet lamp is installed inside the sleeve, and a sealing device is provided between the ultraviolet lamp and the sleeve, forming a tight seal. A lamp head connection device for connecting the ultraviolet lamp to an external power source is provided on the sealing device, and the lamp head connection device is sealed to the sealing device. This structure adds a spring at one end of the lamp head for shock absorption; however, this only reduces axial vibration impact. If the ultraviolet lamp is placed horizontally, the damage to the lamp caused by vibration in the X and Y directions remains unresolved.

[0004] Chinese patent CN105905978B discloses an invention patent entitled "Fixing Device for Heavy-Duty Ultraviolet Lamp Tubes in Marine Ballast Water Systems". The device is equipped with a support sleeve, with elastic feet on the outer wall of the support sleeve. One end of the support sleeve is equipped with a lamp mounting plate, and the lamp mounting plate has a mounting hole in the middle. At least three strip-shaped fixing springs are evenly distributed circumferentially on the inner wall of the mounting hole. One end of the fixing spring is fixedly connected to the inner wall of the mounting hole, and the other end is bent into the support sleeve. The lamp mounting plate is circular, and the outer circumference of the lamp mounting plate is evenly distributed with heat dissipation slots. The mounting hole in the middle of the lamp mounting plate is a circular hole, and the inner wall of the mounting hole is evenly distributed with arc-shaped mounting grooves circumferentially. The fixing springs are installed in the mounting grooves. The part of the fixing spring that is bent into the support sleeve forms an angle of 210° with the axis of the mounting hole. Although the device can clamp and position the lamp tube, providing a certain degree of cushioning and shock absorption, the inner diameter of the support sleeve is fixed, limiting its use to lamp tubes of fixed sizes and making it uncommon. Furthermore, the support sleeve is a separate component, increasing costs and adding additional steps during assembly. Utility Model Content

[0007] The plastic lamp holder includes a cylindrical body with an opening at one end and a closed end at the other end; grooves are evenly distributed on the outer wall of the open end of the cylindrical body; the grooves make the open end elastic.

[0008] Further described, the limiting mechanism includes a reinforcing rib disposed on the inner wall of the cylindrical body and located between adjacent grooves, with one end of the reinforcing rib extending inward to the bottom of the cylindrical body.

[0009] Further description: The shock absorption mechanism includes a boss disposed on the outer wall of the cylindrical body and located between adjacent grooves, the boss being integrally disposed with the cylindrical body; the outer wall of the boss is interference-fitted with the inner wall of the quartz sleeve.

[0012] The accompanying drawings of this utility model are described below: Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a perspective view of the cylindrical body of this utility model; Figure 3 for Figure 2 Side view; Figure 4 This is a cross-sectional view of the cylindrical body of this utility model. Detailed Implementation

[0013] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. However, this utility model is not limited to these embodiments. Any improvements or substitutions based on the basic spirit of these embodiments shall still fall within the scope of protection claimed by the claims of this utility model.

[0014] Example 1: As Figure 1 , 2 As shown in Figures 3 and 4, an ultraviolet lamp includes a lamp tube body fitted inside a quartz sleeve 10. A lamp tube tail 2 is provided at one end of the lamp tube body 1, and a plastic lamp head 3 is provided at the other end of the lamp tube body 1. The lamp tube body 1 is inserted into the plastic lamp head 3. A shock-absorbing mechanism is provided on the outer wall of the plastic lamp head 3, and a limiting mechanism is provided on the inner wall of the plastic lamp head 3.

[0015] The plastic lamp holder 3 refers to a connecting component made of elastic plastic material, specifically polycarbonate or nylon, injection molded to wrap around the end of the lamp tube body 1 and provide deformation cushioning. The shock absorption mechanism is a protruding structure on the outer wall of the plastic lamp holder 3, specifically a boss 7 integrally molded with the lamp holder, used to disperse external vibration energy. The limiting mechanism is a constraint structure on the inner wall of the plastic lamp holder 3, specifically an inwardly extending reinforcing rib 6, used to limit the radial displacement of the lamp tube. Specifically, after the lamp body is inserted into the plastic lamp holder, the shock-absorbing mechanism on the outer wall contacts the inner wall of the quartz sleeve of the ultraviolet lamp through a boss, absorbing vibrations and impacts from different directions; the limiting mechanism on the inner wall fits against the surface of the lamp body through reinforcing ribs, suppressing lateral displacement of the lamp body during vibration. The plastic lamp holder adapts to lamp bodies of different sizes through elastic deformation, eliminating the need for additional structural adjustments. The synergistic effect of the shock-absorbing and limiting mechanisms forms a three-dimensional protective system while simplifying the assembly process. Compared to existing technologies, current axial spring damping solutions can only alleviate vibrations in a single direction, while this solution achieves multi-dimensional vibration buffering through a combination of an outer wall damping mechanism and an inner wall limiting mechanism. Independent support sleeves require adaptation to specific lamp tube sizes and increase assembly steps; this solution, through the integrated design of a flexible plastic lamp holder, reduces costs and improves compatibility with lamp tubes of different sizes. Through the above technical solutions, this application can effectively reduce the impact of multi-directional vibrations on the lamp body 1 and quartz sleeve 10 during transportation and use, reduce filament damage caused by resonance, and extend service life. The integrated design of the plastic lamp holder simplifies the assembly process, and at the same time, it adapts to lamps of different sizes through elastic deformation, improving versatility.

[0016] The plastic lamp holder 3 includes a cylindrical body 4 with an opening at one end and a closed end at the other end; grooves 5 are evenly distributed on the outer wall of the open end of the cylindrical body 4; the grooves 5 make the open end elastic.

[0017] The cylindrical body 4 refers to a plastic component with a cylindrical cavity, which can be achieved using injection molding. The closed end forms an installation reference surface that aligns with the tail of the lamp tube. The groove 5 refers to a recess extending along the axial direction of the cylindrical body 4, which can be machined using an equally spaced annular array, creating an elastic deformation area by reducing the wall thickness at the open end. Specifically, the closed end of the cylindrical body 4 provides a rigid support reference for the lamp holder, while the grooves 5 evenly distributed on the outer wall of the open end divide the cylindrical body 4 into multiple elastic plates. When the lamp tube body 1 is inserted into the inner cavity of the cylindrical body 4, the elastic plates undergo uniform deformation under radial pressure, forming an elastic covering of the lamp tube body 1. The depth and number of grooves 5 are designed so that the open end can absorb lateral vibration energy through elastic deformation while maintaining the assembly clamping force. Under multi-directional impact loads, the elastic plates undergo coordinated deformation, dispersing local stress to the entire circumferential area of ​​the cylindrical body 4. This solution, through the coordinated design of the cylindrical body 1 and the groove 5, enables the lamp head opening end to form a circumferentially continuously distributed elastic support structure, which can not only adapt to lamp tube bodies with different outer diameters, but also simultaneously achieve vibration energy absorption in the XYZ three-axis directions.

[0018] Through the above technical solution, this application achieves elastic deformation control of the lamp holder opening, effectively absorbing multi-directional vibration and impact during transportation and use, and preventing rigid collisions between the lamp tube body 1 and the quartz sleeve 10. The elastic groove structure ensures assembly stability while preventing cracking of the plastic lamp holder 3 due to localized stress concentration through uniform stress distribution. The integrated design of the cylindrical body 1 allows the lamp holder to adapt to lamp tube bodies of different sizes, improving product versatility.

[0019] Further description: The limiting mechanism includes a reinforcing rib 6 disposed on the inner wall of the cylindrical body 4 and located between adjacent grooves 5, with one end of the reinforcing rib 6 extending inward to the bottom of the inner wall of the cylindrical body 4.

[0020] Among them, the reinforcing rib 6 refers to the strip-shaped protrusion extending longitudinally along the inner wall of the cylindrical body 4. Specifically, it can be integrally formed with the cylindrical body using injection molding. Its thickness can be 1.2-1.5 times the wall thickness of the cylindrical body 1, and it is used to provide radial rigid support when the lamp body 1 is inserted. The interval between adjacent grooves 5 refers to the interval between the elastic deformation areas evenly distributed on the outer wall of the open end of the cylindrical body 4. Specifically, it can be formed by setting corresponding protrusion structures in the injection mold. This position retains the basic wall thickness of the cylindrical body 4 to maintain structural strength. Specifically, the reinforcing ribs 6 on the inner wall of the cylindrical body 4 extend longitudinally to the inner bottom between adjacent grooves 5, forming a continuous support structure. When the lamp body 1 is inserted into the cylindrical body 4, the grooves 5 on the outer wall of the open end allow the cylindrical body 4 to undergo elastic deformation to accommodate lamps of different outer diameters, while the reinforcing ribs 6 apply a uniform clamping force to the outer wall of the lamp through their rigid structure. The design of the reinforcing ribs 6 extending to the inner bottom ensures that the lamp is continuously supported axially, preventing longitudinal displacement caused by vibration during transportation or use. At the same time, the spaced distribution of the reinforcing ribs 6 and the grooves 5 forms an area of ​​alternating elasticity and rigidity, suppressing the lateral sway of the lamp caused by resonance in the horizontal direction. Through the above technical solution, this application effectively suppresses the impact between the lamp body 1 and the quartz sleeve 10 caused by vibration during the transportation or use of the ultraviolet lamp, while preventing the filament from breaking due to resonance. The matching structure of the reinforcing rib 6 and the groove 5 allows the limiting mechanism to adapt to lamps of different sizes, and the one-piece molding process reduces production costs and assembly complexity.

[0021] Further description: The shock absorption mechanism includes a boss 7 disposed on the outer wall of the cylindrical body 4 and located between adjacent grooves 5, the boss 7 being integrally disposed with the cylindrical body 4; the outer wall of the boss 7 being interference-fitted with the inner wall of the quartz sleeve 10.

[0022] The boss 7 refers to a block-shaped structure extending outward from the outer wall of the cylindrical body 4. It can be manufactured simultaneously with the cylindrical body 4 using injection molding, and its thickness can be 1.2-1.5 times the wall thickness of the cylindrical body 4. This structure forms rigid support points through the circumferentially distributed bosses 7, absorbing impact energy through its own deformation during vibration. The area between adjacent grooves 5 refers to the interval area between elastic segments formed by the grooves 5 dividing the open end of the cylindrical body 4. Specifically, the open end can be divided into multiple independent elastic segments by evenly distributed grooves 5, with the bosses 7 positioned at the connection points of adjacent elastic segments. This arrangement allows the bosses 7 to both limit the movement of the elastic segments and, through their own deformation, work in synergy with the elastic segments to buffer vibrations. Specifically, the open end of the cylindrical body 4 forms an elastically deformable segment structure through evenly distributed grooves 5, and the boss 7 is disposed in the outer wall area between adjacent grooves 5. When subjected to vibration in the XY direction, the boss 7 and the adjacent elastic segments jointly generate radial deformation, forming a multi-point contact buffer area; axial vibration is dispersed and transmitted through the contact surface between the boss 7 and the external mounting structure. The integrated design of the boss 7 and the cylindrical body 4 eliminates the assembly gap between the traditional independent shock-absorbing pad and the lamp holder. Under vibration impact, the boss 7 and the cylindrical body 4 deform synchronously, avoiding stress concentration caused by material differences. For example, in the horizontal installation state, the three-point support structure formed by the boss and the mounting bracket can decompose the lateral vibration energy, while the elastic compensation space provided by the grooves allows the boss to generate micron-level deformation. This application, through the elastic area formed by the circumferentially distributed bosses 7 and grooves 5, can simultaneously cope with axial, radial, and tangential vibrations.

[0023] This application integrates the shock absorption function into the lamp holder body, eliminating the need for additional assembly processes. Furthermore, the combination design of grooves and bosses adapts to different installation environments, such as maintaining effective contact through elastic deformation even in brackets with a diameter deviation of ±0.5mm.

[0024] Through the above technical solution, this application realizes multi-directional vibration buffering of the lamp tube during transportation and use, avoiding collision damage between the lamp tube body 1 and the quartz sleeve 10; at the same time, the integrated structural design eliminates the need for independent shock-absorbing components, reduces production costs and simplifies the assembly process, and can still maintain the stability of the filament structure under long-term vibration conditions of the pipeline system.

[0025] Furthermore, an annular platform 8 is provided on the outer end face of the closed end of the cylindrical body 4, and a positioning post 9 is vertically provided at the center of the annular platform 8; a spring 11 is provided inside the annular platform 8.

[0026] Among them, the ring platform 8 refers to the annular protrusion structure located on the outer end face of the closed end. Specifically, it can be integrally molded with the cylindrical body using injection molding technology to enhance the impact resistance of the closed end face. The positioning post 9 refers to the columnar structure vertically set at the center of the ring platform 8. Specifically, it can be made of engineering plastic material and molded synchronously with the ring platform to form an axial positioning fit with the external mounting structure. Specifically, the annular support structure of the ring platform 8 can disperse external impact forces and prevent the closed end from deforming or breaking due to vibration. The spring 11 can limit the horizontal displacement of the lamp body 1 and prevent lateral vibration from causing the lamp body 1 to collide with the quartz sleeve 10. The synergistic effect of the ring platform 8 and the spring 11 disperses vibration energy along the axial and radial directions, making up for the deficiency that a single damping structure cannot suppress multi-directional vibration.
