Description

Technical Field

[0001] This utility model belongs to the field of LED aluminum substrate technology, and specifically relates to an LED aluminum substrate fixing device. Background Technology

[0002] With the continuous development of semiconductor technology, semiconductors have been widely used. In particular, LED lights have been widely used due to their energy-saving, long lifespan, and softer light, such as in streetlights and floodlights.

[0003] Chinese patent publication number CN 104075261 A discloses an aluminum substrate fixing device for LED lamps, including a lamp inner tube and an aluminum substrate. The bottom surface of the lamp inner tube is provided with a column for supporting the aluminum plate, and the aluminum substrate is placed on the column. The bottom surface of the lamp inner tube is provided with a locking mechanism.

[0004] However, the current quality inspection device for aluminum substrates has the following problems: it cannot accommodate the joints of LED aluminum substrates of different sizes with the same device, and it cannot guarantee the stability of the LED aluminum substrate after fixing. Therefore, we propose an LED aluminum substrate fixing device. Utility Model Content

[0005] The purpose of this invention is to provide an LED aluminum substrate fixing device that can solve the problems in related technologies where the joints of LED aluminum substrates of different sizes cannot be adapted to the same device, and the stability of the LED aluminum substrate after fixing cannot be guaranteed.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An LED aluminum substrate fixing device includes a lamp holder and a groove. The groove is formed on the circumferential surface of the lamp holder. A circular groove is formed on the inner wall of the groove, and a fixing device is provided on the inner wall of the circular groove. The fixing device includes a sliding groove formed on the inner wall of the groove. A clamping plate is slidably connected to the inner wall of the sliding groove. A circular shaft is fixedly connected to the top of the clamping plate. An annular groove is formed on the inner wall of the groove.

[0008] A force-bearing rod is slidably connected to the inner wall of the annular groove, and a turntable is fixedly connected to the top of the force-bearing rod. A shaped groove runs through the circumference of the turntable, and a force-bearing shaft is fixedly connected to the circumference of the turntable.

[0009] The circular shaft is slidably connected to the inner wall of the irregular groove, and several circular shafts are provided and arranged circumferentially on the inner wall of the circular groove.

[0010] The inner wall of the groove is provided with a blocking mechanism, which includes a ring. The ring is rotatably connected to the circumferential surface of the force-bearing rod. A locking block is fixedly connected to the circumferential surface of the ring. The inner wall of the groove is provided with an action groove.

[0011] The inner wall of the working groove is fixedly connected with a toothed block, and the circumferential surface of the ring is fixedly connected with a torsion spring.

[0012] The toothed blocks and the locking blocks mesh with each other. There are several toothed blocks arranged in a circumferential array on the inner wall of the working groove. The side cross-section of the locking blocks is irregularly shaped.

[0013] The side cross-section of the clamping plate is irregularly shaped. There are several clamping plates arranged in a circular array on the inner wall of the circular groove. There are two circular grooves arranged in a linear array on the inner wall of the recess.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention utilizes components such as clamping plates, round shafts, annular grooves, and force-bearing rods to achieve the sliding of the round shaft on the inner wall of the irregular groove under force. This forces the clamping plates to slide on the inner wall of the groove under force, causing the clamping plates to extend and securely clamp the connector of the LED aluminum substrate. Furthermore, the clamping plates can adapt to connectors of LED aluminum substrates of different sizes, enhancing the capacity of the fixing device. This makes it easier for workers to fix LED aluminum substrates, saving a significant amount of working time and improving work efficiency.

[0016] This invention utilizes components such as a ring, a locking block, an action groove, and a toothed block to work together. When the force-bearing rod continues to slide, and the locking block and the toothed block no longer contact each other, the locking block loses its compressive force. The torsion spring fixed on the circumference of the ring can use its own torque to drive the ring and the locking block to reset and lock onto the side of the toothed block. When workers need to disassemble, they can manually rotate the locking block to complete the disassembly. This effectively avoids the turntable from reversing and ensures the stability of the LED aluminum substrate after it is fixed. Attached Figure Description

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-5 As shown, an LED aluminum substrate fixing device includes a lamp holder 1 and a groove 2. The groove 2 is formed on the circumferential surface of the lamp holder 1. A circular groove 3 is formed on the inner wall of the groove 2. A fixing device 4 is provided on the inner wall of the circular groove 3. The fixing device 4 includes a sliding groove 41, which is formed on the inner wall of the groove 2. A clamping plate 42 is slidably connected to the inner wall of the sliding groove 41. A circular shaft 43 is fixedly connected to the top of the clamping plate 42. An annular groove 44 is formed on the inner wall of the groove 2. The clamping plate 42 can clamp the joint of the LED aluminum substrate.

[0026] A force-bearing rod 45 is slidably connected to the inner wall of the annular groove 44. A turntable 46 is fixedly connected to the top of the force-bearing rod 45. A shaped groove 47 passes through the circumferential surface of the turntable 46. A force-bearing shaft 48 is fixedly connected to the circumferential surface of the turntable 46. The force-bearing rod 45 slides in the inner wall of the annular groove 44, which can effectively limit the movement trajectory of the force-bearing rod 45 when it rotates.

[0027] The circular shaft 43 is slidably connected to the inner wall of the irregular groove 47. Several circular shafts 43 are provided and are arranged in a circular array on the inner wall of the circular groove 3. When the circular shaft 43 slides on the inner wall of the irregular groove 47, it can drive the clamping plate 42 to extend.

[0028] According to the above structure, when the worker needs to install the LED aluminum substrate, the connector of the LED aluminum substrate needs to be aligned with the inner wall of the circular groove 3. Then, by rotating the force shaft 48 counterclockwise, the turntable 46 rotates, forcing the circular shaft 43 to slide on the inner wall of the irregular groove 47, thereby forcing the clamp 42 to slide on the inner wall of the slide groove 41, forcing the clamp 42 to extend and fix the connector of the LED aluminum substrate. The clamp 42 can adapt to connectors of LED aluminum substrates of different sizes, which enhances the capacity of the fixing device 4, making it easier for the worker to fix the LED aluminum substrate, saving a lot of working time and improving work efficiency.

[0029] like Figure 1-5 As shown, the inner wall of the groove 2 is provided with a blocking mechanism 5. The blocking mechanism 5 includes a ring 51, which is rotatably connected to the circumferential surface of the force-bearing rod 45. A locking block 52 is fixedly connected to the circumferential surface of the ring 51. The inner wall of the groove 2 is provided with an action groove 53. When the locking block 52 is subjected to force, it can rotate on the circumferential surface of the force-bearing rod 45 through the ring 51.

[0030] A toothed block 54 is fixedly connected to the inner wall of the groove 53, and a torsion spring 55 is fixedly connected to the circumferential surface of the ring 51. The torsion spring 55 can drive the locking block 52 to reset when the locking block 52 loses force.

[0031] The toothed block 54 and the locking block 52 mesh with each other. There are several toothed blocks 54 arranged in a circumferential array on the inner wall of the working groove 53. The side cross section of the locking block 52 is irregularly shaped. The locking block 52 is locked on the side of the toothed block 54, which can prevent the turntable 46 from rotating.

[0032] The side section of the clamping plate 42 is set to an irregular shape. There are several clamping plates 42, which are arranged in a circular array on the inner wall of the circular groove 3. There are two circular grooves 3, which are arranged in a linear array on the inner wall of the groove 2. The circular groove 3 can adapt to the connectors of LED aluminum substrates of different sizes through the clamping plate 42.

[0033] According to the above structure, after the clamping plate 42 clamps and fixes the connector of the LED aluminum substrate, in order to prevent the turntable 46 from being reversed by external force, when the operator rotates the turntable 46 counterclockwise through the force shaft 48, the force rod 45 slides on the inner wall of the annular groove 44, driving the ring 51 and the locking block 52 to move. When the locking block 52 and the toothed block 54 are in contact with each other, the locking block 52 is subjected to force and rotates on the circumferential surface of the force rod 45 through the ring 51. When the force rod 45 continues to slide, the locking block 52 and the toothed block 54 are no longer in contact with each other, and the locking block 52 loses its squeezing force. The torsion spring 55 fixed on the circumferential surface of the ring 51 can use its own torque to drive the ring 51 and the locking block 52 to reset and lock on the side of the toothed block 54. When the operator needs to disassemble, he can manually rotate the locking block 52 to complete the disassembly, effectively preventing the turntable 46 from being reversed and ensuring the stability of the LED aluminum substrate after fixing.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
