Description

Technical Field

[0001] This utility model relates to the technical field of GX53 lamp holders, specifically a flat, symmetrical snap-fit ​​GX53 lamp holder structure. Background Technology

[0002] In the field of lighting technology, GX53 luminaires are widely used in commercial lighting, home decoration and industrial lighting scenarios due to their compact design and high-efficiency luminous performance. As the core carrier for connecting the luminaire to the power supply, the structural stability and assembly reliability of the lamp holder directly affect the safety performance and service life of the lighting system. Therefore, the research and development of the GX53 lamp holder structure has always been a key focus of the industry.

[0003] Existing GX53 lamp holder structures mostly employ a single-unit housing with screw fixing or a simple plug-in structure. This type of design has drawbacks: on the one hand, traditional single-unit housings lack an effective symmetrical positioning mechanism during assembly, and axial offset or radial misalignment is prone to occur after two assembled housings are joined, leading to poor contact of the conductive sheet and uneven distribution of structural stress; on the other hand, screw fixing or snap-fit ​​structures have the disadvantages of low assembly efficiency and insufficient connection strength. Screw fixing requires tools and is prone to stripping, while simple plug-in structures are prone to loosening due to material fatigue or external impact during long-term use. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a flat, symmetrical snap-fit ​​GX53 lamp holder structure to solve the technical problems existing in the prior art mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flat symmetrical snap-fit ​​GX53 lamp holder structure, comprising two first assembly shells and a second assembly shell, wherein a first assembly shell and a second assembly shell form a group and are assembled by snap-fit; One of the first assembly shells has an annular assembly groove, and the other first assembly shell has an annular assembly block that matches the shape of the assembly groove. When the two first assembled shells are fitted together, there is a predetermined radial interference between the mating surfaces of the assembly block and the assembly groove, forming a self-locking tight fit to achieve axial symmetrical positioning. Preferably, at least four assembly blocks are provided, and the four assembly blocks are evenly distributed circumferentially at 90-degree intervals along the central axis of the first assembly shell; The number of assembly slots on the other first assembly shell is the same as the number of assembly blocks, and their positions correspond one-to-one. Preferably, each of the first assembled shells is symmetrically provided with two conductive sheet limiting frames for accommodating the conductive sheets of the GX53 lamp and limiting their lateral displacement. The second assembly shell has two conductive sheet placement slots, and the positions of the two conductive sheet placement slots correspond to the axial projection positions of the two conductive sheet limiting frames, forming a dual positioning structure for the conductive sheets. Preferably, at least eight docking posts are evenly distributed on the second assembly shell, and eight docking holes are correspondingly provided on the first assembly shell; When the first and second assembled shells are combined, the mating posts and mating holes cooperate to achieve automatic centering and insertion, forming an axial positioning fit; Preferably, the first assembled shell is provided with an annular overlapping platform, and the middle part of the second assembled shell is provided with an annular recess that matches the contour of the overlapping platform. When the first and second assembled shells are combined, the bottom surface of the overlapping platform and the top surface of the recessed part form a surface contact overlap, which enhances the axial bearing capacity of the structure. Preferably, the first assembly shell is provided with at least four elastic snap-fit ​​plates, and the second assembly shell is provided with four snap-fit ​​holes accordingly; When the first and second assembled shells are combined, the elastic snap-fit ​​plate snaps into the snap-fit ​​hole through elastic deformation, forming a detachable snap-fit ​​fixation. Preferably, each of the elastic snap-fit ​​plates has an integrally formed oblique support plate on its side, and the oblique support plate is set at an angle of 30-45 degrees with the elastic snap-fit ​​plate to enhance the bending stiffness of the elastic snap-fit ​​plate. The four snap-fit ​​holes are symmetrically distributed along the circumference of the second assembly shell, and the axial position of the snap-fit ​​holes is located below the recess to avoid structural interference with the overlapping platform.

[0006] In summary, the present invention has the following main advantages: 1. This utility model uses an interference fit design between an annular assembly groove and an annular assembly block, and four assembly blocks evenly distributed circumferentially at 90-degree intervals along the central axis engage with the corresponding assembly groove to form a self-locking tight fit, achieving axial symmetrical positioning of the two first assembly shells. This design not only ensures that the assembled structure has a high degree of symmetry and reduces assembly errors, but also enhances the overall rigidity of the structure through the preload generated by the interference fit, avoiding loosening and deformation caused by external impact or long-term use, thereby improving the stability and service life of the lamp holder structure.

[0007] 2. This utility model forms a multi-level positioning and connection mechanism through the automatic centering and insertion of the docking post of the second assembly shell with the docking hole of the first assembly shell, the surface contact and overlap of the annular overlapping platform and the recessed part, and the elastic snap-fit ​​fixing of the elastic snap-fit ​​plate and the snap-fit ​​hole. This design enables rapid and accurate positioning during the assembly process without additional tools. At the same time, through the axial and radial dual positioning structure of the conductive sheet limiting frame and the conductive sheet placement groove, it ensures that the conductive sheet maintains stable contact during assembly and use, avoids electrical connection failures caused by vibration or displacement, and achieves synergistic optimization of assembly reliability and electrical connection stability.

[0010] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0011] The embodiments of this utility model will be described below based on its overall structure.

[0012] Example Please see Figures 1-5 This utility model provides a technical solution: a flat symmetrical snap-fit ​​GX53 lamp holder structure, including two first assembly shells 1 and second assembly shells 2, one first assembly shell 1 and one second assembly shell 2 are a group, and are assembled by snap-fit; the snap-fit ​​assembly method achieves detachable fixing through the cooperation of elastic snap-fit ​​plate 14 and snap-fit ​​hole 23, which facilitates quick disassembly and maintenance, while ensuring the reliability of structural connection; One of the first assembly shells 1 has an annular assembly groove 10, and the other first assembly shell 1 has an annular assembly block 101 that matches the shape of the assembly groove 10. The annular assembly block 101 and the assembly groove 10 have a radial interference fit, forming a self-locking tight fit to achieve axial symmetrical positioning, effectively preventing loosening after assembly and improving the overall rigidity of the structure. When the two first assembly shells 1 are fitted together, the mating surfaces of the assembly block 101 and the assembly groove 10 have a predetermined radial interference, forming a self-locking tight fit to achieve axial symmetrical positioning. This interference design ensures both smooth insertion during assembly and resistance to vibration and loosening during use, making it suitable for the high-frequency vibration working scenarios of the GX53 lamp. Furthermore, at least four assembly blocks 101 are provided, and the four assembly blocks 101 are evenly distributed in a circle at 90-degree intervals along the central axis of the first assembly shell 1. The even distribution design of the four assembly blocks 101 ensures that the force is evenly distributed when the two first assembly shells 1 are assembled, reducing local stress concentration and improving structural symmetry and assembly stability. The number of assembly slots 10 on the other first assembly shell 1 is the same as the number of assembly blocks 101 and their positions correspond one-to-one; the slot blocks with one-to-one positions cooperate to ensure automatic alignment during assembly, reduce assembly difficulty, and avoid structural damage caused by misalignment. Furthermore, each first assembly shell 1 is symmetrically provided with two conductive sheet limiting frames 11, which are used to accommodate the conductive sheets of the GX53 lamp and limit their lateral displacement; the U-shaped structure design of the conductive sheet limiting frame 11 can effectively constrain the lateral movement of the conductive sheet, and improve the electrical connection stability in conjunction with the subsequent positioning structure. The second assembly shell 2 has two conductive sheet placement slots 21. The positions of the two conductive sheet placement slots 21 correspond to the axial projection positions of the two conductive sheet limiting frames 11, forming a double positioning structure for the conductive sheets. The conductive sheet placement slots 21 corresponding to the axial projection and the conductive sheet limiting frames 11 constitute axial-radial double positioning, ensuring that the conductive sheets maintain accurate positions during assembly and use, and avoiding poor contact. Furthermore, at least eight docking posts 22 are evenly distributed on the second assembly shell 2, and eight docking holes 12 are correspondingly provided on the first assembly shell 1; the docking posts 22 adopt a tapered guide head design, which cooperates with the docking holes 12 to achieve automatic centering and insertion, forming an axial positioning fit, improving assembly accuracy and reducing human operation error; When the first assembled shell 1 and the second assembled shell 2 are combined, the docking post 22 and the docking hole 12 cooperate to achieve automatic centering and insertion, forming an axial positioning fit; this positioning fit enables the first assembled shell 1 and the second assembled shell 2 to automatically correct the offset when they are combined, ensuring the consistency of the structural dimensions after assembly and improving the product qualification rate. Furthermore, the first assembled shell 1 is provided with an annular overlapping platform 13, and the middle part of the second assembled shell 2 is provided with an annular recess that matches the contour of the overlapping platform 13; the annular overlapping platform 13 and the recess are in surface contact overlap, which enhances the axial bearing capacity of the structure and effectively resists external impact. When the first assembled shell 1 and the second assembled shell 2 are combined, the bottom surface of the overlapping platform 13 and the top surface of the recessed part form a surface contact overlap, which enhances the axial load-bearing capacity of the structure. This surface contact design evenly distributes the axial load to the entire contact surface, avoids local crushing, and extends the service life of the structure. Furthermore, the first assembly shell 1 is provided with at least four elastic snap-fit ​​plates 14, and the second assembly shell 2 is provided with four snap-fit ​​holes 23. The elastic snap-fit ​​plates 14 adopt a cantilever beam structure and are snapped into the snap-fit ​​holes 23 through elastic deformation to form a detachable snap-fit ​​fixation, which meets the requirements of rapid assembly while ensuring connection strength. When the first assembly shell 1 and the second assembly shell 2 are combined, the elastic snap-fit ​​plate 14 snaps into the snap-fit ​​hole 23 through elastic deformation, forming a detachable snap-fit ​​fixation; this snap-fit ​​fixation method can complete the assembly without tools, improve production efficiency, and the snap-fit ​​strength meets the usage requirements; Furthermore, each elastic snap-fit ​​plate 14 has an integrally formed oblique support plate 141 on its side, and the oblique support plate 141 is set at an angle of 30-45 degrees with the elastic snap-fit ​​plate 14 to enhance the bending stiffness of the elastic snap-fit ​​plate 14; the triangular reinforcing structure of the oblique support plate 141 improves the bending stiffness of the elastic snap-fit ​​plate 14 and prevents deformation failure during long-term use. Four snap-fit ​​holes 23 are symmetrically distributed along the circumference of the second assembly shell 2, and the axial position of the snap-fit ​​holes 23 is located below the recess, so as to avoid structural interference with the overlapping platform 13. This layout design allows the snap-fit ​​holes 23 to avoid the main load-bearing area, avoid stress concentration, optimize space utilization, and ensure structural compactness.

[0013] The working process of the flat symmetrical snap-fit ​​GX53 lamp holder structure is as follows: First, two first assembly shells 1 are symmetrically assembled; one of the first assembly shells 1 has an annular assembly groove 10, and the other first assembly shell 1 has a protruding annular assembly block 101. During assembly, the assembly block 101 is aligned with the assembly groove 10 along the axial direction and axial pressure is applied. Due to the predetermined radial interference on the mating surface, the two form a self-locking tight fit, completing the axial symmetrical positioning of the two first assembly shells 1; during this process, four assembly blocks 101 evenly distributed circumferentially at 90-degree intervals along the central axis of the first assembly shell 1 engage with the corresponding number and position of the assembly grooves 10 one by one to ensure the symmetry and stability after assembly. Subsequently, the first assembled shell 1 and the second assembled shell 2 are merged. The eight evenly distributed docking posts 22 on the second assembled shell 2 are inserted into the eight docking holes 12 on the first assembled shell 1, and automatic centering and positioning are achieved through the fit, forming an axial positioning fit. At the same time, the annular overlapping platform 13 on the first assembled shell 1 and the annular recess in the middle of the second assembled shell 2 complete the surface contact overlap, enhancing the axial bearing capacity of the structure. During the merging process, the four elastic snap-fit ​​plates 14 on the first assembly shell 1 snap into the corresponding snap-fit ​​holes 23 on the second assembly shell 2 through elastic deformation, forming a detachable snap-fit ​​fixation; the inclined support plate 141 on the side of each elastic snap-fit ​​plate 14 enhances its bending stiffness with an included angle of 30-45 degrees, ensuring the reliability of the snap-fit; the snap-fit ​​holes 23 are symmetrically distributed along the circumference of the second assembly shell 2 and are located axially below the recess, avoiding structural interference with the overlapping platform 13; Finally, the two conductive sheet limiting frames 11 symmetrically arranged on the first assembly shell 1 and the two conductive sheet placement slots 21 on the second assembly shell 2 complete the dual positioning of the conductive sheets; the conductive sheet limiting frames 11 accommodate the conductive sheets and restrict their lateral displacement, and the positions of the conductive sheet placement slots 21 correspond precisely to the axial projection positions of the conductive sheet limiting frames 11, forming a dual positioning structure of axial and radial for the conductive sheets, ensuring the stability of the electrical connection; the entire assembly process requires no additional tools, and fast and reliable assembly is achieved through the snap-fit, interference fit and positioning features of the structure itself.
