Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, and more specifically, to a multi-angle LED lamp assembly. Background Art

[0002] LED lamps are a general term for LED lighting fixtures, which refer to appliances that can transmit, distribute and change the light distribution of LED light sources. They include all parts and components required to fix and protect the LED light source in addition to the LED light source, as well as the circuit accessories necessary for connecting to the power supply. LED is a green light source with the following advantages: DC drive, no flicker; no infrared and ultraviolet components, no radiation pollution, high color rendering and strong luminous directionality; good dimming performance, no visual error when the color temperature changes; cold light sources have low heat generation and are safe to touch.

[0003] Usually, in order to facilitate the adjustment of LED lamps, corresponding rotating or movable structures are used to support the lamps. In order to save costs, the lamps can be adjusted by means of a rotating shaft and a fixing nut. After adjustment, the fixing nut can be tightened to fix the structure. However, in the above scheme, each adjustment requires manual control of the fixing nut, which is more troublesome. Therefore, an elastic buckle structure is adopted in the prior art, and a slot corresponding to the elastic buckle is provided on the moving part. During actual adjustment, the movement of the lamp can be directly manually controlled for adjustment, and the adjusted lamp can be fixed by automatically engaging the elastic buckle structure with the slot.

[0004] In actual use, in order to facilitate manual adjustment of the angle of the lamp, the lamp is generally installed in a lower position. During the process of adjusting the angle of the lamp, there is a certain distance between two adjacent slots, and the elastic buckle cannot be engaged after moving to the position between the two slots, making it inconvenient to accurately adjust the angle of the lamp.

[0023] It should be noted that a sealing ring is installed at the connection between the support rod 72 and the support plate 71 to block the gas; the limit frame 74 is located inside the cavity and away from the space formed between one side of the first spring 76 and the cavity, which is used to reserve space for gas to facilitate gas entry.

[0024] In this embodiment, the implementation scenario is specifically as follows: move the limit plate 9, generate pressure on the airbag 13 through the pressure plate 12, and transport gas to the inside of the two air pipes through the two connecting tubes 15 respectively, so that the gas enters the cavity inside the support plate 71, and then can generate thrust on the moving plate 75, drive the support rod 72 and one end of the friction plate 73, separate the friction plate 73 from the fixed seat 5 or the surface of the lamp body 1, and can release the fixation of the lamp body 1 and the bracket 2.

[0025] For further information, please refer to the attached manual. Figure 3 An arc groove 16 is provided on the outer surface of the fixing seat 5, and two sliders 17 are provided inside the arc groove 16. One end of the two sliders 17 is located outside the fixing seat 5. One side of the two sliders 17 is provided with a connecting rod 18, and one end of the two connecting rods 18 is fixedly connected to the surface of the bracket 2.

[0026] In this embodiment, the implementation scenario is specifically as follows: when the bracket 2 rotates, it drives the connecting rod 18 and the slider 17 to slide along the arc groove 16 on the surface of the fixing seat 5, so that the connecting rod 18 and the bracket 2 rotate synchronously, which can increase the stability between the bracket 2 and the fixing seat 5.

[0027] For further information, please refer to the attached manual. Figure 1 , ear plates 4 are provided on both sides of the mounting plate 3, and two mounting holes are provided on the surfaces of the two ear plates 4.

[0028] In this embodiment, the implementation scenario is specifically as follows: screws are placed inside the mounting holes on the surface of the ear plate 4 , so that the ear plate 4 can be fixed on the wall, and the mounting plate 3 can be fixed.

[0029] Working principle: First, fix the ear plate 4 to the wall with screws to fix the mounting plate 3, then pull the limit plate 9 to make the T-shaped limit blocks 11 on both sides of the limit plate 9 slide along the notches 10 on the surfaces of both sides of the frame 8. The limit plate 9 drives the pressure plate 12 on one side to move to the inside of the frame 8, generating pressure on the airbag 13, compressing the two second springs 14, and the gas inside the airbag 13 passes through two connecting pipes 15 and enters the trachea outside the multiple support plates 71 to transport the gas, and the gas enters the oral cavity inside the support plate 71. And it is located at the connection between the support rod 72 and the movable plate 75. Since a sealing ring is installed at the connection between the support rod 72 and the support plate 71, gas leakage can be prevented, and the gas will generate a certain pressure, which can form a driving force on the movable plate 75, so that the first spring 76 is compressed, and the support rod 72 and the friction plate 73 are driven to move, so that the friction plate 73 is separated from the surface of the lamp body 1 or the fixing seat 5, and the fixing between the bracket 2 and the lamp body 1 and the fixing seat 5 can be released, so that the angle between the lamp body 1 and the bracket 2 and the fixing seat 5 can be adjusted;

[0030] Among them: 1. Close the connecting tube 15 on the side of the frame 8, open the connecting tube 15 on the top of the frame 8, so that the gas enters the air pipe outside the multiple support plates 71 on both sides of the bracket 2, and the angle of the lamp body 1 between the brackets 2 can be adjusted separately.

[0031] By closing the connecting pipe 15 on the top of the frame 8 and opening the connecting pipe 15 on the side of the frame 8, the gas can enter the gas pipe outside the plurality of supporting plates 71 at the rear side of the bracket 2, and the angle between the bracket 2 and the fixing seat 5 can be adjusted separately.

[0032] When adjusting the angle between the bracket 2 and the fixing seat 5, the bracket 2 rotates through the movable rod 6 and drives the connecting rod 18 to rotate along the fixing seat 5. The connecting rod 18 drives the slider 17 to slide inside the arc groove 16 on the surface of the fixing seat 5, so as to support the bracket 2 and improve the stability of the connection between the bracket 2 and the fixing seat 5.

[0033] After the angle adjustment of the lamp body 1 is completed, the limit plate 9 is released, and the elasticity of the two second springs 14 inside the frame 8 generates a rebound force for the pressure plate 12, driving the limit plate 9 and the T-shaped limit block 11 to slide along the notch 10 on the surface of the frame 8, releasing the squeezing of the airbag 13 by the pressure plate 12, so that the airbag 13 is restored to its initial state, which is convenient for repeated use, and the gas inside the mouth of the support plate 71 is discharged, and then the elasticity of the first spring 76 generates power for the moving plate 75 and the support rod 72, so that the friction plate 73 contacts the surface of the fixed seat 5 or the surface of the lamp body 1, and the elasticity of the first spring 76 cooperates with the friction force of the friction plate 73 to fix the bracket 2 and the lamp body 1. The utility model can not only release the fixation of the lamp body 1 and the bracket 2 by moving the position of the friction plate 73, but also adjust the angle of the lamp body 1 and the bracket 2, and the bracket 2 can be supported by the two connecting rods 18 on one side of the bracket 2 to improve the stability of the bracket 2.

[0034] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
