Description

Technical Field

[0002] The light-emitting diode is a commonly used light-emitting device that emits light by releasing energy through the recombination of electrons and holes. It is widely used in the field of lighting. A threaded tube is connected to one end of the light-emitting diode, and the threaded tube is threaded into a threaded sleeve. A metal sheet is connected to the bottom of the threaded sleeve. The end of the threaded tube close to the bottom of the threaded sleeve is connected to a metal abutment block. The light-emitting diode is powered on and emits light through the abutment between the metal sheet and the metal abutment block.

External gas and moisture can easily enter the interior of the diode through the thread gap, thereby damaging the internal components and affecting the service life of the light-emitting diode. Therefore, the sealing effect of LED light-emitting diodes is not ideal at this stage and needs to be improved. Utility Model Content

A sealing platform 2 is provided on one side of the diode body 1. The sealing platform 2 facilitates the sealing effect when the diode body 1 is assembled. A threaded tube 6 is integrally formed at the center of the sealing platform 2. The threaded tube 6 is threadedly connected to the inner wall of the threaded sleeve 10 to realize the assembly between the diode body 1 and the threaded sleeve 10. A boss 9 is integrally formed on one side of the threaded sleeve 10 close to the sealing platform 2. The setting of the boss 9 facilitates the connection between the threaded sleeve 10 and the diode body 1. An array of rectangular cavities 18, circular holes and rectangular cavities 24 are provided on the boss 9. The rectangular cavities 18 and the rectangular cavities 24 both penetrate to the bottom of the boss 9, which facilitates the sealing effect when the diode body 1 and the threaded sleeve 10 are assembled and increases the sealing effect. The boss 9 is located at the bottom of the rectangular cavity 18 and is provided with an annular groove 26. The convex A sealing ring 7 is provided at the annular groove 26 of the platform 9. The sealing ring 7 can be retracted during assembly to achieve effective sealing between the structures. The driven rack 17 and the active rack 23 are respectively slidably connected at the rectangular cavity 18 and the rectangular cavity 24 of the boss 9, and the gear 19 is rotatably connected at the circular hole of the boss 9. The gear 19 is respectively meshed with the driven rack 17 and the active rack 23. When the diode body 1 and the threaded sleeve 10 are assembled, the active rack 23 can be driven to move upward, and then the driven rack 17 is driven to move downward through the relationship of the gear 19, so that the sealing ring 7 is tightly abutted against the sealing platform 2. When the diode body 1 and the threaded sleeve 10 are assembled, the active rack 23 contacts with other components and then moves upward, and the driven rack 17 moves downward through the relationship of the gear 19. The bottom of the driven rack 17 contacts the sealing ring 7, and then the sealing ring 7 is brought closer to the sealing platform 2 to achieve effective sealing between the structures.

[0026] like Figure 1 As shown, in some embodiments, a sealing groove 3 is formed at the sealing platform 2 corresponding to the annular groove 26 , and a sealing ring 5 is adapted to be provided at the sealing groove 3 of the sealing platform 2 .

[0027] It should be noted that when the sealing ring 7 moves downward, it can contact the sealing ring 5 , and the sealing ring 7 and the sealing ring 5 cooperate to achieve sealing protection between the diode body 1 and the threaded sleeve 10 .

[0031] It should be noted that by setting a conical platform 4 between the sealing platform 2 and the threaded tube 6, the conical platform 4 is conical in design, which can increase the contact surface between it and the boss 9. During assembly, the conical platform 4 is adapted to the conical groove of the boss 9 and contacts the special-shaped sealing member 8 on the boss 9, thereby further playing a sealing role and optimizing the sealing effect.

[0032] like Figure 2 As shown, in some embodiments, the lower end of the active rack 23 is provided with an arc surface 25 that matches the contour of the conical platform 4.

[0033] It should be noted that, by providing an arc surface 25 at the lower end of the active rack 23, during assembly, the outer contour of the conical platform 4 contacts the arc surface 25, and the active rack 23 moves upward, so that the active rack 23 and the conical platform 4 can cooperate to achieve stable movement of the active rack 23.

[0034] like Figure 2 As shown, in some embodiments, a give-way cavity 20 is opened in the boss 9 and passes through the rectangular cavity 24.

[0037] It should be noted that after the diode body 1 and the threaded sleeve 10 are assembled, the metal abutment block 16 can be connected to the metal sheet 11 to realize the energization of the diode body 1 .

[0038] The working principle and use steps of the utility model are as follows: during assembly, the threaded tube 6 is threadedly connected to the inner wall of the threaded sleeve 10, and then the tapered platform 4 is adapted to the tapered groove of the boss 9, so that the special-shaped seal 8 at the special-shaped groove 13 contacts the tapered platform 4, and at the same time, one side of the tapered platform 4 abuts against the arc surface 25 at the lower end of the active rack 23, driving the active rack 23 to move upward, and the spring 21 is compressed. At this time, the gear 19 rotates and drives the driven rack 17 to move downward. The lower end of the driven rack 17 is connected to the positioning piece 14 of the sealing ring 7, and then the sealing ring 7 extends downward, so that the sealing ring 7 is tightly abutted against the sealing ring 5, and then an effective seal is achieved at the connection.
