Description

Technical Field

[0001] This utility model relates to the field of automotive lighting processing equipment technology, and in particular to a screw-driving fixture for a multi-faceted warning light. Background Technology

[0002] In the automotive lighting and assembly industry, warning lights are frequently used. Common warning lights have dihedral or tetrahedral structures. Each facet of the warning light emits colored light alternately to alert others. Pentahedral warning lights, however, are widely used due to their smoother dynamic visual effect. During the assembly of a pentahedral warning light, each facet includes a light panel. To ensure effective heat dissipation for each panel, screws are used to secure each panel to each face of a pentagonal radiator.

[0003] Traditional screw-down assembly methods generally rely on manual operation. The operator inserts a light panel into a groove on each facet of a polyhedral heat sink, then places a soft protective pad on the workbench. Holding the pentagonal heat sink in one hand, the operator uses the other to screw the light panels onto the pentagonal heat sink. This process secures the five light panels to the five faces of the pentagonal heat sink. This method has the following technical drawbacks: During the screw-down process, one light panel will inevitably come into contact with the workbench surface. This can damage the optical structural particles on the light panel under external force, leading to their failure or even complete malfunction. Furthermore, this method requires repeated adjustments to the pentagonal heat sink, a tedious and time-consuming process with low efficiency. Additionally, the operator directly touches the optical structural particles on the light panels, and their own static electricity may conduct electricity to these particles, causing further damage. Utility Model Content

[0004] The purpose of this invention is to provide a screw-driving fixture for a polyhedral warning light. This fixture avoids contact with the workbench surface and direct touch by the operator during the process of fixing the light panel of the warning light to the polyhedral heat sink using screws. It also protects the optical structural particles on the light panel, reducing damage to these particles. Furthermore, the polyhedral heat sink ensures its upper surface remains level with each angle change, reducing adjustment time and making the screw-driving operation more time-saving, labor-saving, and efficient.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] This utility model provides a screw-driving fixture for a polyhedral warning light, including a base plate.

The adjusting wheel is movably connected to the fixed frame or movable frame on the same side by a magnetic attraction assembly.

[0008] Preferably, the first fixed wheel is connected to the first adjusting wheel, the first adjusting wheel is sleeved on the first rotating shaft, the second fixed wheel is connected to the second adjusting wheel, and the second adjusting wheel is sleeved on the second rotating shaft.

[0009] Preferably, the polyhedral heat sink includes five planes and has a cross-section that is approximately a regular pentagon. The magnetic attraction assembly includes a first magnetic block and a first magnetic element that are positioned and can be magnetically attracted to each other, and a second magnetic block and a second magnetic element that are positioned and can be magnetically attracted to each other.

[0010] Preferably, the outer side wall of the first adjusting wheel is circumferentially provided with five first magnetic component mounting slots, and each first magnetic component is fixed in one of the first magnetic component mounting slots. The upper end of the fixed frame is provided with a first magnetic block mounting slot, and the first magnetic block is fixed in the first magnetic block mounting slot. The first magnetic block mounting slot is located above the through hole of the fixed frame. The outer side wall of the second adjusting wheel is circumferentially provided with five second magnetic component mounting slots, and each second magnetic component is fixed in one of the second magnetic component mounting slots. The upper end of the movable frame is provided with a second magnetic block mounting slot, and the second magnetic block is fixed in the second magnetic block mounting slot. The second magnetic block mounting slot is located above the through hole of the movable frame.

[0011] Preferably, the side wall of the first adjusting wheel is provided with a first screw hole, and a first screw passes through the first screw hole. When the first screw is tightened, the first screw will abut against the first rotating shaft, so that the first adjusting wheel and the first fixed wheel are fixed together; the side wall of the second adjusting wheel is provided with a second screw hole, and a second screw passes through the second screw hole. When the second screw is tightened, the second screw will abut against the second rotating shaft, so that the second adjusting wheel and the second fixed wheel are fixed together.

[0012] Preferably, the base plate is provided with an elongated groove, a guide rail is provided in the elongated groove, a slider is slidably connected on the guide rail, a fixed plate is fixedly connected above the slider, and the lower end of the movable frame is fixedly connected to the fixed plate.

[0013] Preferably, a limiting block is also fixedly connected to the base plate, the limiting block being located above the guide rail and between the movable frame and the fixed frame.

[0014] Preferably, the lower end of the movable frame is provided with a third magnetic block mounting groove, and a third magnetic block is fixed in the third magnetic block mounting groove. The limiting block is provided with a fourth magnetic block mounting groove, and a fourth magnetic block is fixed in the fourth magnetic block mounting groove. The third magnetic block and the fourth magnetic block are positioned correspondingly and can be attracted by magnetic force.

[0015] The present invention achieves the following beneficial technical effects compared to the prior art:

[0016] The screw-driving fixture for a polyhedral warning light provided by this utility model involves engaging one end of a pentahedral heat sink in the first groove of a first fixed wheel, pushing a movable frame to move it toward the fixed frame, and inserting the other end of the pentahedral heat sink into the second groove of a second fixed wheel. This pentahedral heat sink is thus suspended between the fixed frame and the movable frame. During the process of fixing the warning light panel to the polyhedral heat sink with screws, the light panel is also suspended, preventing contact between the light panel and the workbench surface, avoiding direct touch by the operator, and protecting the optical structural particles on the light panel, thus reducing damage to these particles. Rotate the first adjusting wheel so that one of the first magnetic elements on the first adjusting wheel attracts the first magnetic block. Simultaneously rotate the second adjusting wheel so that one of the second magnetic elements on the second adjusting wheel attracts the second magnetic block. Then rotate the first or second fixed wheel so that the upper surface of the pentahedral heat sink is in a horizontal state. Then tighten the first screw so that the first screw abuts against the first rotating shaft, and tighten the second screw so that the second screw abuts against the second rotating shaft. This fixes the first adjusting wheel, the first fixed wheel, the pentahedral heat sink, the second adjusting wheel, and the second fixed wheel together, allowing the lamp panel to be fixed to the upper surface of the pentahedral heat sink with screws. When it is necessary to rotate the pentahedral heat sink to fix the lamp panel to the next plane with screws, rotate the first or second adjusting wheel so that an adjacent first magnetic element attracts the first magnetic block or an adjacent second magnetic element attracts the second magnetic block. The next plane is then in a horizontal state, allowing the lamp panel to be fixed with screws again. This ensures that each rotation of the first or second adjusting wheel aligns the corresponding plane of the pentahedral heat sink with a horizontal position, until all five planes are secured to the light panel with screws, resulting in the assembled pentahedral warning light. By rotating the angle of the magnetic component on the adjusting wheel, the angle of the planes of the pentahedral heat sink is rotated, ensuring that each screwing operation occurs on a horizontal plane. This allows the light panel to be secured to the horizontal upper surface with screws, reducing adjustment time and making the screwing operation more efficient and less labor-intensive.

Detailed Implementation

[0022] This utility model provides a screw-driving fixture for a multi-faceted warning light, such as... Figures 1-4 As shown, the system includes a base plate 1, with a fixed frame 2 fixedly connected to one end and a movable frame 3 slidably connected to the other end. Specifically, the base plate 1 has an elongated groove 4, which is arranged along the line connecting the movable frame 3 and the fixed frame 2. A guide rail 5 is provided inside the elongated groove 4, and a slider 6 is slidably connected to the guide rail 5. A fixed plate 7 is fixedly connected above the slider 6, and the lower end of the movable frame 3 is fixedly connected to the fixed plate 7. This allows the movable frame 3 to move in a direction closer to or further away from the fixed frame 2, and allows the movable frame 3 to slide smoothly along the guide rail 5, thereby facilitating the adjustment of the distance between the movable frame 3 and the fixed frame 2.

[0023] A first fixed wheel 8 is rotatably connected to the fixed frame 2. The first fixed wheel 8 has a first groove 9 on one side and a first rotating shaft 10 on the other side. The upper part of the fixed frame 2 has a fixed frame through hole 11. The first rotating shaft 10 is rotatably connected to the fixed frame through hole 11 via a bearing, thus achieving a rotatable connection between the first fixed wheel 8 and the fixed frame 2. A second fixed wheel 12 is rotatably connected to the movable frame 3. The second fixed wheel 12 has a second groove 13 on one side and a second rotating shaft 14 on the other side. The upper part of the movable frame 3 has a movable frame through hole 15. The second rotating shaft 14 is rotatably connected to the movable frame through hole 15 via a bearing. The fixed frame through hole 11 and the movable frame through hole 15 are opposite each other, thus achieving a rotatable connection between the second fixed wheel 12 and the movable frame 3. The two ends of the polyhedral heat sink are engaged in the first groove 9 and the second groove 13, realizing the fixed connection between the polyhedral heat sink and the first fixed wheel 8 and the second fixed wheel 12. This allows the polyhedral heat sink to be stably fixed between the first fixed wheel 8 and the second fixed wheel 12, ensuring that the polyhedral heat sink will not shake randomly during the screwing process of the polyhedral warning light panel to the polyhedral heat sink, further improving the quality and stability of screwing. Specifically, the two ends of the polyhedral heat sink are respectively matched with the shapes of the first groove 9 and the second groove. During operation, one end of the polyhedral heat sink is inserted into the first groove 9 of the first fixed wheel 8, and the movable frame 3 is pushed and moved towards the fixed frame 2, thereby driving the second fixed wheel 12 to move. When the other end of the polyhedral heat sink is inserted into the second groove 13 of the second fixed wheel 12, the second fixed wheel 12 stops moving. At this time, the polyhedral heat sink is fixed between the first fixed wheel 8 and the second fixed wheel 12, and the polyhedral heat sink is suspended between the fixed frame 2 and the movable frame 3. In this way, when the light panel of the polyhedral warning light is fixed to each face of the polyhedral heat sink with screws, the contact between the light panel and the base plate 1 is avoided, and the direct touch of the operator is also avoided, thus protecting the optical structure particles on the light panel. After the screw fixing assembly of the light panel is completed on the polyhedral heat sink, the movable frame 3 can be pushed and moved away from the fixed frame 2. In this way, the assembled warning light will be disengaged from the second fixed wheel 12, and the staff can remove the assembled warning light from the fixed frame 2, thus realizing the convenient access of the warning light.

[0024] In this embodiment, the polyhedral heat sink is a regular pentahedral heat sink, that is, it includes five planes and the cross-section is approximately a regular pentagon. The first fixed wheel 8 is connected to the first adjusting wheel 16, and the first adjusting wheel 16 is sleeved on the first rotating shaft 10, realizing the rotational connection between the first adjusting wheel 16 and the fixed frame 2. The second fixed wheel 12 is connected to the second adjusting wheel 26, and the second adjusting wheel 26 is sleeved on the second rotating shaft 14, realizing the rotational connection between the second adjusting wheel 26 and the movable frame 3. Five first magnetic component mounting slots 17 are evenly distributed circumferentially on the outer side wall of the first adjusting wheel 16. Each first magnetic component mounting slot 17 contains a first magnetic component (not shown). The upper end of the fixed frame 2 is provided with a first magnetic block mounting slot 18, and each first magnetic block mounting slot 18 contains a first magnetic block (not shown). The first magnetic component and the first magnetic block can be magnetically attracted. The first magnetic block mounting slot 18 is located above the through hole 11 of the fixed frame. When the first adjusting wheel 16 is rotated, the first magnetic block corresponds to the position of the uppermost first magnetic component and can be magnetically attracted. The outer side wall of the second adjusting wheel 26 has five circumferentially distributed second magnetic component mounting slots 19, each containing a second magnetic component (not shown). The upper end of the movable frame 3 has a second magnetic block mounting slot 20, each containing a second magnetic block (not shown). The second magnetic components and the second magnetic blocks are magnetically attracted to each other. The second magnetic block mounting slot 20 is located above the through hole 15 of the movable frame. When the second adjusting wheel 26 is rotated, the second magnetic blocks and the uppermost second magnetic component are positioned correspondingly and magnetically attracted to each other. Since the magnetic components on the adjusting wheel are circumferentially distributed, the angular interval between each magnetic component matches the angular interval between the planes of the pentahedral heat sink. For the pentahedral heat sink in this embodiment, the included angle between adjacent planes is the same as the angular interval between adjacent magnetic components. The first adjusting wheel 16 has a first screw hole 21 on its side wall, through which a first screw passes. When the first screw is tightened, it abuts against the first rotating shaft 10, thus fixing the first adjusting wheel 16 to the first fixed wheel 8. The second adjusting wheel 26 has a second screw hole 22 on its side wall, through which a second screw passes. When the second screw is tightened, it abuts against the second rotating shaft 14, thus fixing the second adjusting wheel 26 to the second fixed wheel 12. This fixing method ensures that the adjusting wheel and the fixed wheel will not rotate relative to each other during the screwing process, thereby ensuring the stability of the pentagonal heat sink and the accuracy of the pentagonal warning light position. When it is necessary to adjust the plane position of the pentagonal heat sink, simply loosen the screw, rotate the adjusting wheel to the appropriate position, and then tighten the screw. The operation is simple and reliable.

[0025] Specifically, after the pentahedral heat sink is engaged between the first fixed wheel 8 and the second fixed wheel 12, the first adjusting wheel 16 is rotated so that a first magnetic element on the first adjusting wheel 16 attracts a first magnetic block. Simultaneously, the second adjusting wheel 26 is rotated so that a second magnetic element on the second adjusting wheel 26 attracts a second magnetic block. Then, either the first fixed wheel 8 or the second fixed wheel 12 is rotated so that the upper surface of the pentahedral heat sink is in a horizontal state. At this point, the first screw is tightened so that it abuts against the first rotating shaft 10, thus fixing the first adjusting wheel 16 to the first fixed wheel 8. The second screw is tightened so that it abuts against the second rotating shaft 14, thus fixing the second adjusting wheel 26 to the second fixed wheel 12. At this point, the first adjusting wheel 16, the first fixed wheel 8, the pentahedral heat sink, the second adjusting wheel 26, and the second fixed wheel 12 are all fixedly connected. Since the upper surface of the pentahedral heat sink is in a horizontal state, it is convenient to perform screw assembly operations on the upper surface, that is, to fix the lamp board to the upper surface of the pentahedral heat sink using screws. When the adjusting wheel rotates, the magnetic component rotates along with it. When it rotates to the position corresponding to the magnetic block, the magnetic component attracts the corresponding magnetic block, and the position of the adjusting wheel corresponds to one plane of the pentahedral heat sink. Since the angle between adjacent planes is the same as the angular interval between adjacent magnetic components, the pentahedral heat sink rotates by the angle of one magnetic component each time the adjusting wheel rotates. This ensures that the upper surface of the pentahedral heat sink is horizontal after each rotation, facilitating the fixing of the lamp board screws to the upper surface. Therefore, when it is necessary to rotate the pentahedral heat sink to perform screwing operations on the next plane, only the first adjusting wheel 16 or the second adjusting wheel 26 needs to be rotated, simplifying the operation and improving the accuracy and efficiency of screwing.

[0026] A limiting block 23 is also fixedly connected to the base plate 1. The limiting block 23 is located above the guide rail 5 and between the movable frame 3 and the fixed frame 2. The limiting block 23 can limit the sliding of the movable frame 3 and prevent the movable frame 3 from sliding excessively and colliding with the fixed frame 2. The lower end of the movable frame 3 is provided with a third magnetic block mounting groove 24, in which a third magnetic block (not shown) is fixed. The limiting block 23 is provided with a fourth magnetic block mounting groove 25, in which a fourth magnetic block (not shown) is fixed. The third magnetic block and the fourth magnetic block are positioned correspondingly and can be magnetically attracted. The distance between the end of the limiting block 23 away from the fixed frame 2 and the fixed frame 2 matches the length of the pentahedral heat sink. Through the magnetic attraction of the third and fourth magnetic blocks, when the movable frame 3 slides close to the limiting block 23, it can play a buffering and positioning role, so that the pentahedral heat sink will not move randomly after being fixed, ensuring the accuracy of the screw-driving operation.

[0027] The screw-driving fixture for a polyhedral warning light provided by this utility model, in specific application, involves engaging one end of the pentahedral heat sink in the first groove 9 of the first fixed wheel 8, pushing the movable frame 3 to move it toward the fixed frame 2, and inserting the other end of the pentahedral heat sink into the second groove 13 of the second fixed wheel 12. The movable frame 3 stops moving when the third and fourth magnetic blocks attract each other. The first adjusting wheel 16 is rotated so that one of its first magnetic elements attracts the first magnetic block, and simultaneously the second adjusting wheel 26 is rotated so that one of its second magnetic elements attracts the second magnetic block. Then, either the first fixed wheel 8 or the second fixed wheel 12 is rotated so that the upper surface of the pentahedral heat sink is horizontal. Finally, the first screw is tightened so that it abuts against the first rotating shaft 10, and the second screw is tightened so that it abuts against the second rotating shaft 14. This connects the first adjusting wheel 16, the first fixed wheel 8, the pentahedral heat sink, the second adjusting wheel 26, and the second fixed wheel 12 together. The upper surface of the pentahedral heat sink can be fixed with screws to secure the lamp panel. When it is necessary to rotate the pentahedral heat sink to screw the lamp panel onto the next plane, rotate the first adjusting wheel 16 or the second adjusting wheel 26 to make an adjacent first magnetic element attract the first magnetic block or an adjacent second magnetic element attract the second magnetic block. The next plane will then be in a horizontal state, allowing for screwing. Each rotation of the first adjusting wheel 16 or the second adjusting wheel 26 will make the corresponding plane of the pentahedral heat sink horizontal until all five planes are screwed to secure the lamp panel, resulting in an assembled pentahedral warning light. Then, push the moving frame 3 and move it away from the fixed frame 2 to remove the assembled pentahedral warning light.

[0028] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
