Description

Technical Field

[0001] The present invention relates to the technical field of lighting devices, and in particular to an anti-glare lighting device for a training bench. Background Art

[0002] A fitter is a type of work that mainly relies on manual operations and uses various tools to complete manufacturing, assembly, and repair. Generally, when performing fitter operations, it is necessary to ensure uniform illumination in the working area and avoid the appearance of light spots or shadows to ensure the feasibility and consistency of the surface of the workpiece to be processed. On existing training benches, there are usually three light sources. One light source irradiates the workpiece to be processed on the training bench surface, and the other two light sources are located on the front and back sides of the first light source as auxiliary lighting for irradiating the square hole hanging plate and aisle of the training bench, and do not directly irradiate the workpiece to be processed. When students are practicing fitter work, it is easy for the illumination of one irradiation light source on the training bench (the other two light sources are only auxiliary) to be blocked by the shadow of the hand or tool, and the irradiation angle of the light source is fixed and not convenient to adjust. Summary of the Invention

[0003] Therefore, in view of the above problems, the present invention proposes an anti-glare lighting device for a training bench, which can adjust the irradiation angle of the light source, and has a wider irradiation range to avoid the workpiece to be processed being blocked by shadows.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] An anti-glare lighting device for a training bench, comprising a first lamp board, a lamp fixture connecting member provided on the top of the first lamp board, a lamp fixture adjusting bracket connected to the lamp fixture connecting member, second lamp boards provided on the front and back sides above the first lamp board, and a first driving mechanism for driving the two-axis rotation of the second lamp boards;

[0006] The first driving mechanism includes right-angle seats provided on the front and back sides of the top surface of the first lamp board, a first connecting rod rotatably provided on the right-angle seat away from the second lamp board side, a second connecting rod rotatably provided on the top of the right-angle seat, a third connecting rod rotatably connected to the first connecting rod and the second connecting rod, and a first driving device for driving the rotation of the third connecting rod. The second lamp board is provided on the third connecting rod, and the two sides of the first connecting rod and the second connecting rod are vertically distributed.

[0007] Further, the first driving device is a rotating shaft provided between the right-angle seats. The rotating shaft is connected to the second connecting rod, a fixed rod is fixedly connected to the outside of the rotating shaft, and a first driving cylinder is provided between the fixed rod and the top surface of the first lamp board.

[0008] Further, the first driving device includes a transmission box disposed between the right-angle seats, a first transmission shaft rotatably disposed on one side of the transmission box, a second transmission shaft rotatably disposed on the other side of the transmission box, and a second driving mechanism for driving the first transmission shaft and the second transmission shaft to rotate in the same direction or in opposite directions. The first transmission shaft is connected to a second connecting rod in front of the first lamp panel, and the second transmission shaft is connected to a second connecting rod behind the first lamp panel.

[0009] Further, the second driving mechanism includes a driving gear rotatably disposed in the transmission box, a first motor for driving the driving gear to rotate, a first bevel gear disposed on one side of the transmission box and meshing with the driving gear, a second bevel gear disposed on the other side of the transmission box and meshing with the driving gear, a flat key disposed outside the second transmission shaft, a transmission cylinder slidably disposed outside the second transmission shaft and the flat key, an adjusting block slidably disposed on the side of the transmission box away from the driving gear, and a second driving cylinder for driving the adjusting block to move laterally. The first bevel gear is fixed on one side of the first transmission shaft, and the first transmission shaft is located inside the transmission box. The second bevel gear is disposed outside the second transmission shaft. The adjusting block is connected to the transmission cylinder. A plurality of first convex teeth are provided on one side of the first bevel gear, a plurality of second convex teeth are provided on one side of the second bevel gear, and grooves for contacting the first convex teeth and the second convex teeth are provided on both sides of the adjusting block.

[0010] Further, the lamp adjusting bracket includes an upper horizontal pipe connected to the lamp connecting member, an upper L-shaped pipe slidably disposed inside the upper horizontal pipe, a vertical pipe slidably disposed outside the upper L-shaped pipe, a lower L-shaped pipe slidably disposed at the bottom of the vertical pipe, and an external connecting pipe disposed outside the lower L-shaped pipe. Upper adjusting knobs for fixing the upper L-shaped pipe are provided on the upper horizontal pipe and the vertical pipe, and lower adjusting knobs for fixing the lower L-shaped pipe are provided on the vertical pipe and the external connecting pipe.

[0011] By adopting the foregoing technical solutions, the beneficial effects of the present invention are as follows:

[0012] For the anti-glare lighting device of this training bench, through the setting of the lamp adjusting bracket, when the irradiation angle needs to be adjusted, the first driving device drives the second connecting rods on the front and rear sides to rotate. The second connecting rods rotate 80°-90° along the connection with the rotating shaft. The second connecting rods drive the third connecting rods to rotate, so that the second lamp panel on the third connecting rod is distributed in a cross shape with the first lamp panel, and the irradiation range is wider. When processing a workpiece to be processed, due to the single light source irradiation, the workpiece to be processed is easily blocked by shadows. When the second lamp panel needs to be adjusted to be perpendicular above the first lamp panel, the first driving device drives the second connecting rod to rotate reversely.

[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation modes.

[0037] Refer to Figures 1 to 18 In this embodiment, a glare-proof lighting device for a training platform is provided, including a first lamp board 1, a lamp fixture connecting piece 2 arranged on the top of the first lamp board 1, a lamp fixture adjusting bracket 3 connected to the lamp fixture connecting piece 2, second lamp boards 4 arranged on the front and rear sides above the first lamp board 1, and a first driving mechanism 5 for driving the two-axis rotation of the second lamp boards 4.

[0038] As Figure 3 and Figure 4, with the x-axis, y-axis, and z-axis as reference lines, the first driving mechanism 5 includes right-angle seats 501 provided on the front and rear sides of the top surface of the first lamp board 1, a first connecting rod 502 rotatably provided on the side of the right-angle seat 501 away from the second lamp board 4 and rotating along the z-axis, a second connecting rod 503 rotatably provided on the top of the right-angle seat 501 and rotating along the y-axis, a third connecting rod 504 rotatably connected to the first connecting rod 502 and the second connecting rod 503, and a first driving device 505 for driving the third connecting rod 504 to rotate. The second lamp board 4 is provided on the third connecting rod 504. The two sides of the first connecting rod 502 and the second connecting rod 503 are vertically distributed. The connection point between the first connecting rod 502 and the third connecting rod 504 is located on the x-axis, and the connection point between the second connecting rod 503 and the third connecting rod 504 is located on the z-axis. The connection point between the right-angle seat 501 and the first connecting rod 502 has a first extension axis a, and the connection point between the right-angle seat 501 and the second connecting rod 503 has a second extension axis b. The included angle between the first extension axis a and the second extension axis b is 95° - 105°.

[0039] The first driving device 505 is a rotating shaft 506 provided between the right-angle seats 501. The rotating shaft 506 is connected to the second connecting rod 503. A fixed rod 507 is fixedly connected to the outside of the rotating shaft 506. A first driving cylinder 508 is provided between the fixed rod 507 and the top surface of the first lamp board 1.

[0040] When it is necessary to drive the rotating shaft 506 to rotate, the first driving cylinder 508 expands and contracts to control the rotating direction of the rotating shaft 506, which is beneficial to controlling the direction of the second lamp board 4.

[0041] The first driving device 505 includes a transmission box 509 provided between the right-angle seats 501, a first transmission shaft 514 rotatably provided on one side of the transmission box 509, a second transmission shaft 515 rotatably provided on the other side of the transmission box 509, and a second driving mechanism for driving the first transmission shaft 514 and the second transmission shaft 515 to rotate in the same direction or in opposite directions. The first transmission shaft 514 is connected to the second connecting rod 503 in front of the first lamp board 1, and the second transmission shaft 515 is connected to the second connecting rod 503 behind the first lamp board 1. The second driving mechanism is beneficial to controlling the first transmission shaft 514 and the second transmission shaft 515 to rotate in the same direction, or the first transmission shaft 514 and the second transmission shaft 515 to rotate in opposite directions simultaneously, so as to control the irradiation angle of the second lamp board 4.

[0042] The second driving mechanism includes a driving gear 510 rotatably arranged in the transmission case 509, a first motor 511 for driving the driving gear 510 to rotate, a first bevel gear 512 arranged on one side of the transmission case 509 and meshing with the driving gear 510, a second bevel gear 513 arranged on the other side of the transmission case 509 and meshing with the driving gear 510, a flat key 516 arranged outside the second transmission shaft 515, a transmission cylinder 517 slidably arranged outside the second transmission shaft 515 and the flat key 516, an adjusting block 518 slidably arranged on the side of the transmission case 509 away from the driving gear 510, and a second driving cylinder 519 for driving the adjusting block 518 to move horizontally. The first bevel gear 512 is fixed on one side of the first transmission shaft 514, and the first transmission shaft 514 is located inside the transmission case 509. The second bevel gear 513 is arranged outside the second transmission shaft 515. The adjusting block 518 is connected to the transmission cylinder 517. A plurality of first convex teeth 520 are arranged on one side of the first bevel gear 512, a plurality of second convex teeth 521 are arranged on one side of the second bevel gear 513, and grooves 522 in contact with the first convex teeth 520 and the second convex teeth 521 are arranged on both sides of the adjusting block 518.

[0043] In the initial state, the first motor 511 drives the driving gear 510 to rotate. The driving gear 510 drives the first bevel gear 512 and the second bevel gear 513 to rotate. The first bevel gear 512 drives the first transmission shaft 514 fixedly arranged on one side to rotate. The groove 522 on the horizontal side of the adjusting block 518 contacts the first convex teeth 520 on one side of the first bevel gear 512. Since the middle of the adjusting block 518 is connected to the flat key 516 and the second transmission shaft 515, when the first bevel gear 512 rotates, it will drive the adjusting block 518 to rotate through the first convex teeth 520. The adjusting block 518 drives the second transmission shaft 515 to rotate through the flat key 516. At this time, the first transmission shaft 514 and the second transmission shaft 515 will rotate in the same direction. The first transmission shaft 514 and the second transmission shaft 515 respectively drive the second lamp plates 4 on the front and rear sides to rotate through the second connecting rods 503, so that the second lamp plates 4 move from above the first lamp plate 1 to a position where they are in a parallel plane and are distributed in a cross shape.

[0044] When it is necessary to adjust the front and rear two second lamp panels 4 to opposite irradiation angles after completion, the second driving cylinder 519 drives the adjusting block 518 to move horizontally. The adjusting block 518 drives the groove 522 on one side of the transmission cylinder 517 to contact the second convex tooth 521 on one side of the second bevel gear 513. Due to the action of the driving gear 510, the rotation directions of the first bevel gear 512 and the second bevel gear 513 are opposite. The adjusting block 518 is driven by the second bevel gear 513, and the rotation direction of the second transmission shaft 515 driven is opposite to the rotation direction of the first transmission shaft 514. The second lamp panels 4 located on the front and rear sides of the first lamp panel 1 will rotate in opposite directions, and the front and rear two second lamp panels 4 will form a V-shaped angle. When it is necessary to restore, the front and rear two second lamp panels 4 return to the parallel state. The second driving cylinder 519 drives the adjusting block 518 to move towards the first bevel gear 512 side. The groove 522 on one side of the adjusting block 518 contacts the first convex tooth 520, and the initial state will be restored, thereby adjusting the second lamp panel 4 back above the second lamp panel 4 to restore the original irradiation. The irradiation angle of the second lamp panel 4 can be adjusted to avoid the dazzling influence caused by the irradiation angle of the second lamp panel 4, and the irradiation angle of the second lamp panel 4 can be adjusted according to the shape of the workpiece to be processed to reduce the irradiation dead angle. After processing is completed, the irradiation angle in the initial state can be restored by moving the position of the transmission cylinder 517. Compared with the first driving device 505, the adjustable angle range of the second lamp panel 4 of this second driving mechanism is larger, and the irradiation angle of the second lamp panel 4 is improved.

[0045] The lamp adjusting bracket 3 includes an upper horizontal tube 301 connected to the lamp connecting member 2, an upper L-shaped tube 302 slidably disposed in the upper horizontal tube 301, a vertical tube 303 slidably disposed outside the upper L-shaped tube 302, a lower L-shaped tube 304 slidably disposed at the bottom of the vertical tube 303, and an external connecting tube 305 disposed outside the lower L-shaped tube 304. The upper horizontal tube 301 and the vertical tube 303 are provided with upper adjusting knobs 306 for fixing the upper L-shaped tube 302, and the vertical tube 303 and the external connecting tube 305 are provided with lower adjusting knobs 307 for fixing the lower L-shaped tube 304.

[0046] When it is necessary to adjust the position of the first lamp panel 1, the upper adjusting knob 306 can be loosened, and after completion, the upper horizontal tube 301 is pulled to one side, so as to adjust the front and rear positions of the first lamp panel 1. When it is necessary to adjust the height of the first lamp panel 1, the lower adjusting knob 307 outside the vertical tube 303 is loosened, and then the upper L-shaped tube 302 is longitudinally moved, thereby driving the upper horizontal tube 301 to move longitudinally, so as to adjust the height of the first lamp panel 1, which can be adjusted according to the actual use situation.

[0047] On the top surface of the first lamp board 1, there is a detection flashlight 6. The detection flashlight 6 includes a flashlight housing 601, an LED lamp 602 provided at the bottom of the flashlight housing 601, a heat conduction plate 603 provided on the top surface of the LED lamp 602, a heat dissipation hole 604 provided on the outer side of the flashlight housing 601 and at the position of the heat conduction plate 603, heat conduction pipes 605 provided on the transverse two sides of the heat conduction plate 603, a partition plate 606 provided inside the top of the flashlight housing 601 for the heat conduction pipes 605 to pass through, a first circulation pipeline 607 provided at the top of one transverse side of the heat conduction pipe 605, a second circulation pipeline 608 provided at the top of the other transverse side of the heat conduction pipe 605, a partition hole 609 provided on the top of the flashlight housing 601 for the first circulation pipeline 607 and the second circulation pipeline 608 to pass through, a pump 610 and a heat dissipation row 611 provided on the top surface of the first lamp board 1, a connecting pipe 612 provided between the pump 610 and the heat dissipation row 611, and a filter 613 communicated with the heat dissipation row 611. The first circulation pipeline 607 is connected to the pump 610, and the second circulation pipeline 608 is connected to the filter 613.

[0048] During use, the heat conduction plate 603 is attached to the back of the LED lamp 602. The heat conduction plate 603 conducts the heat source on the back of the LED lamp 602. The heat conduction plate 603 transfers the heat to the top fins. The heat conduction pipes 605 located at the bottom are also attached to the back of the LED lamp 602 to conduct heat. When the coolant in the first circulation pipeline 607 and the second circulation pipeline 608 passes through the heat conduction pipes 605, it will absorb the heat of the heat source. The coolant is transported to the pump 610 through the first circulation pipeline 607. The pump 610 transports it to the heat dissipation row 611 through the connecting pipe 612. The heat dissipation row 611 is a liquid-cooled radiator with a built-in fan to cool the liquid. The cooled coolant is transported to the second circulation pipeline 608 through the filter 613 to cool the heat conduction plate 603 and the LED lamp 602. The first circulation pipeline 607 and the second circulation pipeline 608 are located above the partition plate 606. The components connecting the first circulation pipeline 607 and the second circulation pipeline 608 to the heat conduction pipes 605 are separately provided inside the partition plate 606 and the flashlight housing 601, which can prevent liquid leakage at the positions of the first circulation pipeline 607 and the second circulation pipeline 608 and the heat conduction pipes 605 from causing short circuit damage to the LED lamp 602 and reduce the risk brought by water-cooled liquid leakage. Moreover, both the heat conduction pipes 605 and the fins on the back of the heat conduction plate 603 are provided inside the heat conduction plate 603. When the heat dissipation row 611 needs to be maintained, the LED lamp 602 can operate for a period of time. Within 1 hour of starting up, the heat conduction plate 603 can continue to provide effective heat dissipation for the LED lamp 602, avoiding the disadvantage that the LED lamp 602 needs to be shut down for maintenance due to the short water-cooled maintenance cycle. The water-cooled components, the pump 610, the heat dissipation row 611, and the filter 613 are located on the first lamp board 1, which can reduce the weight of the detection flashlight 6 and have good heat dissipation performance, avoiding the high heat of the detection lamp cover or other LED lamps with light transmission performance affecting the service life of the LED lamp 602.

[0049] The filter 613 includes a transparent tube 614, a framework 615 disposed inside the transparent tube 614, a cylinder 616 disposed in the middle of the framework 615, a first sector support piece 617 fixedly disposed on the outer side of the front end of the cylinder 616, a first sector filter screen 618 disposed on the first sector support piece 617, a first arc-shaped hole 619 disposed on the outer side of the cylinder 616 and close to the direction of the first sector filter screen 618, a first circular filter screen 620 disposed in the middle of the cylinder 616, and a second circular filter screen 621 disposed on the side of the cylinder 616 away from the first circular filter screen 620.

[0050] A plurality of second sector support pieces 622 distributed in a spiral shape are spaced apart on the outer side of the cylinder 616, an included angle of 90° is formed between each of the second sector support pieces 622, a second sector filter screen 623 is disposed on each of the second sector support pieces 622, a second arc-shaped hole 624 is disposed on the outer side of the cylinder 616 and outside the second sector filter screen 623, a raised enclosure plate 625 is disposed on the outer sides of the first sector filter screen 618 and the second sector filter screen 623, the outer sides of the first sector support piece 617 and the second sector support piece 622 are attached to the inner circular surface of the transparent tube 614 and can be inserted into the transparent tube 614, both sides of the transparent tube 614 are connected to the second circulation pipeline 608 and the heat dissipation row 611, and the mesh aperture of the first sector filter screen 618, the second sector filter screen 623, the first circular filter screen 620, and the second circular filter screen 621 is 150 micrometers.

[0051] After long-term use, impurities in the coolant will clog the heat dissipation row 611 and the heat conduction tube 605, affecting the rotation speed and flow rate of the pump 610. Although the existing mesh filter can collect impurities, it clogs quickly and needs to be replaced frequently. By setting the filter 613, the coolant is divided into two streams on the inner and outer sides of the cylinder 616. When the coolant passes through the outer side, since the four first sector-shaped support pieces 617 and the second sector-shaped support pieces 622 form a 90° angle, the first sector-shaped filter net 618 and the three second sector-shaped filter nets 623 will filter the coolant passing through the outer side of the cylinder 616. After the coolant passes through the first sector-shaped filter net 618 and the second sector-shaped filter nets 623, the impurities on the coolant will adhere to the surface, and the baffle 625 will prevent the impurities from leaking out of the first sector-shaped filter net 618 and the second sector-shaped filter nets 623. The liquid passing through the inner side of the cylinder 616 will be blocked and collected by the first circular filter net 620 and the second circular filter net 621. Since there are first arc-shaped holes 619 at the positions of the first sector-shaped filter net 618 and the second sector-shaped filter nets 623 on the outer side of the cylinder 616, when the first circular filter net 620 on the inner side of the cylinder 616 is clogged with a lot of impurities, the coolant will flow out through the first arc-shaped holes 619 and the second arc-shaped holes 624. The liquid passes through the first sector-shaped filter net 618 and the second sector-shaped filter nets 623 on the outer side. When the second circular filter net 621 becomes clogged, blocked and diverted by the baffle 625, the liquid will flow back to the inner side of the cylinder 616 through the second arc-shaped holes 624 and be filtered by the second circular filter net 621, completing the filtration of the coolant. The first sector-shaped filter net 618, the second sector-shaped filter nets 623, the first circular filter net 620 and the second circular filter net 621 of this filter 613 perform segmented filtration, with a long service life. When some areas are clogged, it does not affect the liquid flow rate, improving the durability of the existing filter 613.
