[0003] During the processing of LED tubes, it is necessary to fix the tubes to facilitate subsequent processing. For example, the utility model disclosed in CN215548019U discloses a fixing device for LED tube processing. This fixing device is equipped with a clamping component, and a hydraulic cylinder drives the clamping component to move up and down, thereby facilitating the clamping of the LED tube. At the same time, the clamping component and the hydraulic cylinder are detachably connected, so different types of clamping components can be replaced when processing LED tubes of different sizes, thereby improving the fixing effect of the LED tube.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] First embodiment: like Figure 1-4 As shown, the present invention proposes a support and fixing mechanism for lamp tube processing, including a base plate 1 and a support seat 2 fixedly installed at the center of the upper surface of the base plate 1. A connecting seat 3 is rotatably connected to the support seat 2, and a placement plate 4 is fixedly connected to the upper end of the connecting seat 3. The base plate 1 is provided with an adjusting component 7 for adjusting the vertical rotation of the connecting seat 3.

[0022] In this invention, the clamping member 5, in conjunction with the adjusting member 7, can fix and support lamp tubes of different specifications and shapes, and adjust the angle of the lamp tubes after they are fixed.

[0023] The adjusting component 7 includes a threaded rod 71 rotatably connected to the support base 2. A driving block 72 is threadedly connected to the threaded rod 71. An adjusting rod 73 with one end hinged to the upper end of the driving block 72 is provided. A threaded hole is provided in the middle of the driving block 72, and the threaded hole is adapted to the thread on the outside of the threaded rod 71, so that the rotating threaded rod 71 can drive the driving block 72 to move horizontally toward the side closer to or away from the support base 2.

[0024] In an optional embodiment, the placement tray 4 is provided with a clamping member 5 for supporting and fixing the lamp tube; The clamping component 5 includes four support rods 56. The placement plate 4 has four through holes 51 arranged in a cross shape. The four support rods 56 are fixedly connected to the four through holes 51. Each support rod 56 is slidably connected to an adjusting block 55. Each adjusting block 55 is fixedly connected to the inner side of each through hole 51. Each adjusting block 55 is fixedly connected to a mounting block 52 that is slidably connected to the upper end of the placement plate 4. Each mounting block 52 has a groove 510 on its upper surface. Each groove 510 contains a first support block 53 that extends out of the groove 510. The end of each first support block 53 that extends into the groove 510 is T-shaped, and a first clamping block 54 is fixedly connected to its T-end.

[0025] In this embodiment, during the process of the adjusting block 55 being abutted, it can drive the four mounting blocks 52 to move and adjust towards the center of the placement plate 4, so as to drive the first support block 53 and the first clamping block 54 on the mounting block 52 to clamp and fix the cylindrical lamp tube vertically or horizontally.

[0026] It should be noted that the mounting block 52 is provided with an elastic support member for supporting and limiting the first support block 53; the lower surface of the placement plate 4 is provided with a driving member 6 for driving the four adjusting blocks 55 to move and adjust towards the center of the placement plate 4; the driving member 6 includes a rotating ring 62 rotatably connected to the lower surface of the placement plate 4, a mounting bracket 61 fixedly connected to one side of the placement plate 4, and a worm gear 65 rotatably connected to the mounting bracket 61, a worm rack 64 fixedly connected to the outer side of the rotating ring 62, and the worm rack 64 meshing with the worm gear 65, and four pressing blocks 63 fixedly connected to the inner side of the rotating ring 62, which are distributed in a ring at equal intervals. The rotating worm gear 65, in cooperation with the worm rack 64 meshing with it, can drive the rotating ring 62 to rotate axially, so that after the pressing blocks 63 on the inner side of the rotating ring 62 press the adjusting blocks 55, the four adjusting blocks 55 can slide towards the center of the placement plate 4 in the through hole 51, as well as a pressing support spring 57.

[0027] Each of the four first clamping blocks 54 has a first fixing groove on one side facing the center of the placement plate 4, and the specifications of the first fixing groove are compatible with the specifications of the end of the straight cylindrical lamp tube, so that the first fixing groove on the first clamping block 54 can clamp and fix the end of the straight cylindrical lamp tube.

[0028] In addition, the adjusting block 55 is convex in shape and its lower end is round. The side of the pressing block 63 near the adjusting block 55 is inclined, so that the pressing block 63 can press the adjusting block 55 to move in the through hole 51 during rotation. The number of pressing blocks 63 corresponds to the number of adjusting blocks 55.

[0029] In an optional embodiment, the elastic support includes a limiting block 58 with one end penetrating through the mounting block 52 and extending into the interior of the first support block 53. The limiting block 58 is slidably connected to the mounting block 52. The end of the limiting block 58 that does not penetrate the mounting block 52 is T-shaped, and a return spring 59 is fixedly connected between the T-shaped end and the mounting block 52. The end of the limiting block 58 that extends into the interior of the first support block 53 is inclined. The first support block 53 has a support groove for the limiting block 58 to slide and extend. There are eight limiting blocks 58, and the eight limiting blocks 58 are symmetrically distributed in pairs on each mounting block 52.

[0030] In this embodiment, when the first support block 53 is pressed and placed inside the groove 510, it can squeeze the inclined end of the limiting block 58 and squeeze the limiting block 58 to slide away from the first support block 53, and stretch the reset spring 59. After the inclined end of the limiting block 58 is aligned with the support groove on the first support block 53, it can be reset by the reset spring 59 and drive its inclined end to extend into the support groove to support and limit the first support block 53.

[0031] Second embodiment: In an optional embodiment, the clamping member 5 further includes a second support block 511 placed in the right groove 510, a third support block 512 placed in the front and rear grooves 510, and a second clamping block 515 fixedly connected to one end of the second support block 511 and the third support block 512 extending out of the groove 510, and a fourth support block 513 placed in the left groove 510, and two abutments 514 fixedly connected to one end of the fourth support block 513 extending out of the groove 510.

[0032] In this embodiment, the driven mounting block 52 can drive the second clamping block 515 and the abutment block 514 on the second support block 511, the third support block 512 and the fourth support block 513 to abut and fix the end of the U-shaped tube, as well as the front and rear sides and the side away from the end, so as to achieve the clamping and fixing of the U-shaped tube.

[0033] It should be noted that the two abutment blocks 514 are symmetrically distributed on one end of the groove 510 extending from the fourth support block 513. The second clamping block 515 is provided with a second fixing groove on one side near the center of the placement plate 4, which is adapted to the outer surface of the U-shaped lamp tube. The second fixing groove is arc-shaped, so that the second clamping block 515 can fit better with the outer surface of the U-shaped lamp tube. The second support block 511 has the same specifications as the first support block 53. The length of the third support block 512 located at one end inside the groove 510 is greater than the length of the first support block 53. The width of the fourth support block 513 extending out of one end of the groove 510 is greater than the width of the first support block 53.

[0034] The abutment 514 and the second clamping block 515 on the second support block 511, the third support block 512 and the fourth support block 513 can be synchronously fitted with the surface and end of the U-shaped lamp tube when moving with the mounting block 52. The second support block 511, the third support block 512 and the fourth support block 513 are also provided with a support groove for the limiting block 58 to limit and support one end of the second support block 511, the third support block 512 and the fourth support block 513 located inside the groove 510.

[0035] The working principle in the above embodiments is as follows: The rotating worm 65, in conjunction with the meshing worm 64, can drive the rotating ring 62 to rotate axially. After the squeezing block 63 on the inner side of the rotating ring 62 squeezes and contacts the adjusting block 55, it can drive the four adjusting blocks 55 to slide in the through hole 51 toward the center of the placement plate 4. The squeezing support spring 57, when the adjusting block 55 is moved by the contact, can drive the four mounting blocks 52 to move and adjust toward the center of the placement plate 4, so as to drive the first support block 53 and the first clamping block 54 on the mounting block 52 to clamp and fix the cylindrical lamp tube vertically or horizontally. Since the first support block 53 is limited and locked by the limiting block 58, by replacing the corresponding second support block 511, third support block 512 and second clamping block 515 into the groove 510 of the mounting block 52, the moving mounting block 52 drives the abutment 514 and the second clamping block 515 on the second support block 511, third support block 512 and second clamping block 515 to clamp and fix the end, front and rear sides and the side away from the end of the U-shaped lamp tube. Meanwhile, by disassembling the first support block 53, the second support block 511, the third support block 512, and the second clamping block 515, and replacing the first clamping block 54, the second clamping block 515, and the stop block 514 with different specifications of first fixing groove and second fixing groove, it is possible to fix straight cylindrical lamp tubes and U-shaped lamp tubes of different specifications. When the drive block 72 is moved closer to or further away from the support base 2 by rotating the threaded rod 71, the adjusting rod 73 can be driven to push and pull the connecting seat 3 on the support base 2 to adjust the angle of the lamp tube on the placement plate 4 after it is fixed, so as to further improve the processing efficiency of the lamp tube.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
