Abstract
Description
Technical Field
[0001] This utility model relates to the field of light bulb core technology, and more specifically, to a shockproof structure for light bulb cores. 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.
[0003] Currently, commonly used LED bulb core column shockproof structures only achieve shockproofing through the spiral structure of the conductor, which has poor shockproofing effect and poor heat dissipation. For example, the bulb core column shockproof structure disclosed in publication number CN 217983267 U includes a lamp holder, a light strip, and a glass cover. The lamp holder has a core column, and a metal conductor is provided inside the core column. The core column has a through hole, and the first end of the metal conductor extends out of the core column through the through hole. The metal conductor extending out of the core column is spirally bent to form an elastic conductive end, and the light strip is connected to the elastic conductive end.
[0004] As can be seen from the above-disclosed scheme, the shockproof structure of the bulb core column uses the elastic conductive end formed by spiral bending to provide shockproof protection. Its shockproof effect may not meet people's needs. In addition, the core column is a solid body and is connected to the lamp holder as one piece, which not only makes the core column heavy, but also makes its heat dissipation effect poor. Utility Model Content
[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a shock-absorbing structure for a light bulb wick column. This shock-absorbing structure, through the outer column, inner column, and buffer block set in the wick column body, makes the wick column a composite wick column. The outer column bears the vertical load, while the inner column provides deformation capacity. The two work together to resist vibration, greatly improving the shock-absorbing effect. Furthermore, the outer column and the hollow groove are hollow structures, which not only greatly reduces the weight of the wick column and reduces the risk of falling and breaking, but also fills the hollow groove with insulating heat-dissipating oil, which disperses vibration energy through thermal convection and improves the heat dissipation effect of the wick column.
[0006] To solve the above problems, the present invention adopts the following technical solution.
[0007] A light bulb wick shockproof structure includes a light bulb body, which includes a lamp holder. One end of the lamp holder has a transparent cover, and a metal contact is fixedly connected to the bottom of the lamp holder. The wick body is fixedly connected to the end face of the lamp holder and is located inside the transparent cover. A metal conductor is fixedly connected inside the lamp holder. The metal conductor includes a first conductor and a second conductor, and one end of the first and second conductors has an elastic conductive end. This light bulb wick shockproof structure, through the outer column, inner column, and buffer block set in the wick body, makes the wick a composite wick. The outer column bears the vertical load, and the inner column provides deformation capacity. The two work together to resist vibration, greatly improving the shockproof effect. Furthermore, the outer column and the hollow groove are hollow structures, which not only greatly reduce the weight of the wick and reduce the risk of drop and breakage, but also fill the hollow groove with insulating heat-dissipating oil, which disperses vibration energy through thermal convection and improves the heat dissipation effect of the wick.
[0008] Furthermore, the lamp wick body includes an outer column and an inner column. One end of the outer column is fixedly connected to the end face of the lamp holder, and the other end of the outer column is provided with a clearance groove. A connection hole is opened at the bottom of the clearance groove. The clearance groove makes the outer column a hollow structure, which can reduce the weight of the wick and also has the function of clearance.
[0009] Furthermore, the inner column is located within the clearance groove, and a first buffer block and a second buffer block are fixedly connected to both ends of the inner column. The outer sides of the first buffer block and the second buffer block are provided with external protruding rings. The first buffer block and the second buffer block have the function of buffering and shock absorption, and can also seal the opening of the clearance groove.
[0010] Furthermore, the inner wall of the clearance groove is provided with a first sealing groove and a second sealing groove. The inner wall of the first sealing groove is engaged with the surface of the first buffer block, and the inner wall of the second sealing groove is engaged with the surface of the second buffer block. The first sealing groove and the second sealing groove ensure the connection stability of the first buffer block and the second buffer block.
[0011] Furthermore, the surfaces of the first and second guide bars are fixedly connected to the interior of the inner column, and one end of the first and second guide bars is provided with a serpentine bend, which has a buffering effect and at the same time enables the inner column in the clearance groove to have a deformation buffering function.
[0012] Furthermore, both the first buffer block and the second buffer block have a central hole at their center, and the inner wall of the central hole has an inner convex ring, which can increase the connection between the first buffer block, the second buffer block and the inner column.
[0013] Furthermore, the interior of the recessed groove is filled with insulating heat-dissipating oil, which has the function of conducting and dissipating heat.
[0014] Compared with existing technologies, the advantages of this utility model are:
[0015] (1) This scheme uses an outer column, an inner column and a buffer block to make the core column a composite core column. The outer column bears the vertical load and the inner column provides deformation capacity. The two work together to resist vibration, which greatly improves the anti-vibration effect.
[0016] (2) The outer column and the hollow groove set in this scheme are hollow structures, which can not only greatly reduce the weight of the core column and reduce the risk of falling and breaking, but also fill the hollow groove with insulating heat dissipation oil, disperse the vibration energy through heat convection, and improve the heat dissipation effect of the core column.

The bottom of the clearance groove 31 has two connection holes 32. The inner walls of the lamp are fixedly connected to the surfaces of the first guide bar 51 and the second guide bar 52, respectively. The hollow groove 31 makes the outer column 3 hollow, which can reduce the weight of the core column and also has the function of avoiding voids. The interior of the hollow groove 31 is filled with insulating heat dissipation oil, which has the function of conducting heat and dissipating heat. The insulating heat dissipation oil is silicone oil or natural ester oil. The lamp core column body 2 is located inside the transparent cover 11. The interior of the lamp head 1 is fixedly connected with a metal conductor 5. The metal conductor 5 includes the first guide bar 51 and the second guide bar 52. One end of the first guide bar 51 and the second guide bar 52 is provided with an elastic conductive end 53. The surface of the elastic conductive end 53 is connected with a light-emitting strip, and light is emitted through the current of the elastic conductive end 53.
[0027] The inner column 4 is located within the clearance groove 31. A first buffer block 41 and a second buffer block 42 are fixedly connected to both ends of the inner column 4. The first buffer block 41 and the second buffer block 42 are made of silicone. An outer protruding ring 44 is provided on the outer side of both the first buffer block 41 and the second buffer block 42. The first buffer block 41 and the second buffer block 42 have the function of buffering and shock absorption, and can also seal the opening of the clearance groove 31. The inner wall of the clearance groove 31 is provided with a first sealing groove 33 and a second sealing groove 34. The inner wall of the first sealing groove 33 is engaged with the surface of the first buffer block 41, and the inner wall of the second sealing groove 34 is engaged with the surface of the second buffer block 42.

The inner wall of the center hole 43 is provided with an inner convex ring 45, which can increase the connection firmness of the first buffer block 41, the second buffer block 42 and the inner column 4.
[0029] When the bulb is subjected to vibration, the first buffer block 41 and the second buffer block 42 can buffer the vibration force. At the same time, the insulating heat dissipation oil disperses the vibration energy through thermal convection, thus providing secondary buffering. Then, the elastic conductive end 53 provides a third buffering effect, extending the life of the bulb. The outer column 3, inner column 4 and buffer blocks set in the bulb column body 2 make the bulb a composite bulb column. The outer column 3 bears the vertical load and the inner column 4 provides deformation capacity. The two work together to resist vibration, which greatly improves the shockproof effect. In addition, the outer column 3 and the hollow groove 31 are hollow structures, which can not only greatly reduce the weight of the bulb and reduce the risk of falling and breaking, but also fill the hollow groove 31 with insulating heat dissipation oil, which disperses the vibration energy through thermal convection, thus improving the heat dissipation effect of the bulb column.
