Description

Technical Field

[0001] This utility model relates to the field of dual-filament light bulb technology, and more specifically, to a dual-filament light bulb structure. Background Technology

[0002] LED bulbs have advantages such as high speed, high efficiency, long life and energy saving, and their application in daily life is becoming more and more widespread. Dual-core bulbs are a type of LED bulb, which are special bulb structures with two internal bulb cores.

[0003] Currently, most common dual-filament light bulbs connect the filaments by welding, which not only limits the length of the filaments but also results in low assembly efficiency. For example, CN 215112137 U discloses a dual-filament light bulb structure, which includes a bulb shell, a lamp holder, a mounting bracket, and filaments. The mounting bracket is located inside the bulb shell, and one end of the bulb shell is connected to the lamp holder. The mounting bracket is fixed to the end of the lamp holder located inside the bulb shell, and two filaments are fixed on the mounting bracket.

[0004] As can be seen from the above-mentioned publicly available scheme, the lamp wick is fixed to the mounting bracket by welding or other methods. This not only results in low positioning efficiency, but also makes it impossible to replace the lamp wick when a defect is found during bulb testing, causing the entire bulb to be scrapped, which wastes resources. Furthermore, the mounting bracket can only fix lamp wicks of a certain length, which narrows the scope of application. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a dual-wick bulb structure. This dual-wick bulb structure, through the threaded part of the central rod and the upper and lower adjusting sleeves, allows the spacing of the two axial mounting plates to be adjusted, thereby fixing wicks of different lengths. Moreover, the mounting plates have a buffering and shock-absorbing function. Furthermore, through the setting of the limiting rod, insert rod, anti-detachment plate and insertion hole, the wick and the mounting plate are fixed by snap-fit, which not only improves the assembly efficiency, but also facilitates the replacement of defective wicks.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A dual-wick bulb structure includes a bulb body, which includes a bulb holder. One end of the bulb holder is fixedly connected to a metal contact, and the other end of the bulb holder is fixedly mounted with a bulb housing. A support assembly is fixedly connected to the center of the bulb holder. The support assembly includes a central rod, and an upper adjustment sleeve and a lower adjustment sleeve are threadedly connected to the surface of the central rod. Clamping assemblies are provided on the sides of the upper and lower adjustment sleeves, and a light-emitting component is engaged between two axially symmetrical clamping assemblies. This dual-wick bulb structure, through the threaded portion of the central rod and the upper and lower adjustment sleeves, allows the spacing between two axially mounted plates to be adjusted, thereby fixing bulbs of different lengths. The mounting plates also have a buffering and shock-absorbing function. Furthermore, the setting of a limiting rod, a plug rod, an anti-detachment plate, and a plug hole ensures that the bulb is fixed to the mounting plate through a snap-fit ​​connection, which not only improves assembly efficiency but also facilitates the replacement of defective bulbs.

[0008] Furthermore, the clamping assembly includes a mounting plate made of an elastic metal plate. One end of the mounting plate is provided with a bending portion, and one end of the bending portion is provided with a pressing portion. The surface of the pressing portion has insertion holes, and the serpentine bending portion has a buffering and shock-absorbing function.

[0009] Furthermore, the surface of the center rod is provided with an upper thread and a lower thread, the external threads of the upper thread and the lower thread are in opposite directions, and the center positions of the upper adjusting sleeve and the lower adjusting sleeve are both provided with threaded holes, so that the upper adjusting sleeve and the lower adjusting sleeve will not move up or down synchronously.

[0010] Furthermore, the light-emitting component includes a lamp core body, with limiting rods fixedly connected to both ends of the lamp core body. The limiting rods are made of conductive metal, and the end face of the limiting rod is movably connected to the surface of the extrusion part. The extrusion part is in a state of compression and elasticity, and contacts and extrudes the end face of the limiting rod, thus ensuring conductive stability.

[0011] Furthermore, one end of the limiting rod is fixedly connected to an insertion rod, the surface of the insertion rod is movably connected to the inner wall of the insertion hole, the outer diameter of the insertion rod is smaller than the inner diameter of the limiting rod, and the limiting rod is used to restrict the insertion position of one end of the insertion rod.

[0012] Furthermore, the side of the insertion rod has radially symmetrical grooves, and the inner wall of the grooves is fixedly connected to an anti-detachment plate. The grooves have a void-avoiding function and are used to store the anti-detachment plate.

[0013] Furthermore, the anti-detachment plate is arc-shaped and made of an elastic metal sheet. After being squeezed, the anti-detachment plate automatically resets due to elasticity, which can limit the insertion position of the plug rod.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution uses the threaded part of the center rod and the upper and lower adjusting sleeves to make the two mounting plates in the axial direction adjustable, thereby fixing lamp wicks of different lengths. Moreover, the mounting plates have the function of buffering and shock absorption.

[0016] (2) This solution uses a limit rod, plug rod, anti-detachment plate and plug hole to fix the lamp core to the mounting plate by snap-fit, which not only improves the assembly efficiency, but also facilitates the replacement of defective lamp cores. Attached Figure Description

[0024] 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.

[0025] Example 1

[0026] Please see Figure 1-5A dual-wick light bulb structure includes a bulb body 1, which includes a lamp holder 11. The lamp holder 11 is a metal shell with an external insulating layer. A metal contact 13 is fixedly connected to one end of the lamp holder 11, and a bulb shell 12 made of transparent glass is fixedly mounted to the other end of the lamp holder 11. A support assembly 2 is fixedly connected to the center of the lamp holder 11. The support assembly 2 includes a central rod 21, and an upper adjusting sleeve 24 and a lower adjusting sleeve 25 are threadedly connected to the surface of the central rod 21. Clamping assemblies are provided on the sides of the upper adjusting sleeve 24 and the lower adjusting sleeve 25. The clamping assemblies include mounting plates 26 made of elastic metal plates, and the length of the wick body 31 is greater than the length of the mounting plates 26 at both ends. The spacing between the lamp core body 31 and the two mounting plates 26 is such that the two ends of the lamp core body 31 are clamped to the two mounting plates 26 by elastic force, thus avoiding poor conductivity. One end of the mounting plate 26 is provided with a bending part 27, and the other end of the bending part 27 is provided with a pressing part 28. The surface of the pressing part 28 has an insertion hole 29. The serpentine bending part 27 has a buffering and shock absorption function, and the light-emitting component 3 is snapped between the two axially symmetrical clamping components. The light-emitting component 3 includes the lamp core body 31. The two ends of the lamp core body 31 are fixedly connected to limit rods 32. The limit rods 32 are made of conductive metal. The end face of the limit rod 32 is movably connected to the surface of the pressing part 28. The pressing part 28 is in a state of compression and elastic force, and contacts and presses the end face of the limit rod 32 to ensure conductivity stability.

[0027] The surface of the center rod 21 is provided with an upper threaded portion 22 and a lower threaded portion 23. The external threads of the upper threaded portion 22 and the lower threaded portion 23 are opposite in direction. The center positions of the upper adjusting sleeve 24 and the lower adjusting sleeve 25 are both provided with threaded holes, so that the upper adjusting sleeve 24 and the lower adjusting sleeve 25 will not move up or down synchronously. One end of the limiting rod 32 is fixedly connected to the insertion rod 33. The surface of the insertion rod 33 is movably connected to the inner wall of the insertion hole 29. The outer diameter of the insertion rod 33 is smaller than the inner diameter of the limiting rod 32. The limiting rod 32 is used to limit the insertion position of one end of the insertion rod 33.

[0028] The side of the insertion rod 33 has radially symmetrical grooves 34. The inner wall of the groove 34 is fixedly connected to an anti-detachment plate 35. The groove 34 has the function of preventing air leakage and is used to store the anti-detachment plate 35. The anti-detachment plate 35 is arc-shaped and made of elastic metal sheet. After being squeezed, the anti-detachment plate 35 automatically resets by elastic force, which can limit the insertion position of the insertion rod 33.

[0029] When installing the lamp core body 31, the spacing between the upper adjusting sleeve 24 and the lower adjusting sleeve 25 can be adjusted according to the length of the lamp core body 31. The upper adjusting sleeve 24 moves down clockwise and rises up counterclockwise, while the lower adjusting sleeve 25 rises clockwise and moves down counterclockwise. After the spacing between the upper adjusting sleeve 24 and the lower adjusting sleeve 25 is adjusted, the insertion rods 33 at both ends of the lamp core body 31 are inserted into the insertion holes 29. At this time, the limiting rod 32 and the anti-detachment plate 35 limit the insertion position of the insertion rods 33. Through the threaded part of the central rod 21 and the upper adjusting sleeve 24 and the lower adjusting sleeve 25, the spacing of the two mounting plates 26 in the axial direction can be adjusted, thereby fixing lamp cores of different lengths. Moreover, the mounting plate 26 has a buffering and shock absorption function, extending the service life of the bulb. Furthermore, through the limiting rod 32, insertion rods 33, anti-detachment plate 35 and insertion holes 29, the lamp core and the mounting plate 26 are fixed by snap-fit, which not only improves the assembly efficiency, but also facilitates the replacement of defective lamp cores.

Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
