[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0035] Reference Figure 1 , Figure 2 and Figure 4 The utility model provides an embodiment: an expandable rear stand for laser equipment, including a column frame 1, a screw 2 is rotatably connected inside the column frame 1, the top of the screw 2 passes through the column frame 1 and is fixedly connected to a locking gear 3, the top of the locking gear 3 is fixedly connected to a worm gear 4, the top of the column frame 1 is fixedly connected to an upper cover 7, and a driving component is installed inside the upper cover 7. Through the driving component, the user can rotate the handle 6, thereby driving the worm 5 to rotate, thereby driving the worm gear 4 and the locking gear 3 to rotate, and then driving the screw 2 to rotate. Through the rotation of the screw 2, the threaded sleeve 8 slides up and down under the guidance of two graphite guide rails 21, so as to adjust the height of the laser marking head 10 to meet the needs of different products. A locking component is provided on the outside of the locking gear 3, the outer wall of the screw 2 is threadedly connected to the threaded sleeve 8, the side of the threaded sleeve 8 away from the screw 2 is fixedly connected to a mounting frame 9, the side wall of the mounting frame 9 is installed with a prompt component, and the side of the mounting frame 9 away from the threaded sleeve 8 is installed with a laser marking head 10. The mounting bracket 9 can ensure the stability of the laser marking head 10. The position of the laser marking head 10 can be accurately adjusted by combining the screw 2 and the threaded sleeve 8. At the same time, the locking assembly can effectively prevent the screw 2 from rotating due to vibration or external force during use, further ensuring the stability of the marking head 10.
[0036] Reference Figure 4 , Figure 6 and Figure 7The locking assembly includes a limit shell 15, the bottom of the limit shell 15 is fixedly connected to the top of the column frame 1, the inner bottom wall of the limit shell 15 is fixedly connected with an air bag 16, the top of the air bag 16 is fixedly connected with a latch 18, and a spring 19 is fixedly connected between the top of the latch 18 and the inner top wall of the limit shell 15. Through the compression and expansion of the air bag 16, the latch 18 can be pushed to move along the limit groove 20, thereby unlocking the locking gear 3. At this time, the user can rotate the handle 6 to adjust the position of the laser marking head 10. When the adjustment is completed, the air bag 16 will shrink, and the action of the spring 19 will cause the latch 18 to re-lock the locking gear 3 to ensure the locking effect.
[0037] Reference Figure 7 The inner walls of both sides of the limiting shell 15 are provided with limiting grooves 20, and the latching teeth 18 are slidably connected between the two limiting grooves 20. The latching teeth 18 can move in the limiting grooves 20 to ensure its precise guidance, and at the same time, it can also ensure that the latching teeth 18 effectively release the locking pressure when the airbag 16 expands, thereby unlocking the locking gear 3, and can be re-engaged and locked as the air pressure restores balance after adjustment.
[0038] Reference Figure 2 and Figure 6 One end of the latch 18 passes through the limit shell 15 and engages with the locking gear 3. Under normal conditions, the screw 2 is locked by the cooperation of the latch 18 and the locking gear 3 to prevent the device from rotating under the action of external force, resulting in deviation in the position of the laser marking head 10. Graphite guide rails 21 are fixedly connected on both sides of the inner wall of the column frame 1, and the outer side of the threaded sleeve 8 is slidably connected between the two graphite guide rails 21. The bottom of the column frame 1 is fixedly connected with a base 22. The graphite guide rail 21 has good wear resistance and low friction coefficient, which ensures the smooth movement of the threaded sleeve 8 and reduces the wear during its activity, so that the accuracy during adjustment can meet production requirements, thereby ensuring the precise adjustment of the laser marking head 10.
[0039] Reference Figure 1 , Figure 4 and Figure 5The drive assembly includes a worm 5, which is rotatably connected to the inside of the upper cover 7, and meshes with the worm 5 and the worm wheel 4. One end of the worm 5 passes through the upper cover 7 and is fixedly connected to the handle 6. The outside of the handle 6 is fixedly connected to a rubber bag 12. The inside of the worm 5 and the handle 6 are provided with a cavity 11 that is interconnected. The bottom wall of the cavity 11 is provided with an air hole 13. The end of the worm 5 away from the handle 6 is rotatably connected to the outside of a sealing ring 14. A connecting pipe 17 is connected between the sealing ring 14 and the air bag 16. The bottom of the sealing ring 14 is fixedly connected to the top of the column frame 1. The drive assembly uses the transmission design of the worm 5 and the worm wheel 4 so that the rotation of the handle 6 can accurately control the height adjustment of the laser marking head 10, and with the help of the cooperation of the worm 5 and the worm wheel 4, the screw 2 can be further self-locked and limited. At the same time, the rubber bag 12 is compressed to increase the air pressure in the cavity 11, and the air pressure is introduced into the sealing ring 14 through the air hole 13 on the cavity 11, and finally introduced into the interior of the air bag 16 through the connecting pipe 17, so as to drive the locking assembly. In addition, with the cooperation of the sealing ring 14, the worm 5 can ensure rotation without affecting the circulation of the internal air pressure.
[0040] Reference Figure 5 The sealing ring 14 is connected to the inside of the cavity 11 through the air hole 13, and the inside of the rubber bag 12 is connected to the cavity 11. During the operation of the rubber bag 12, the air pressure in the cavity 11 can be transmitted to the air bag 16 through the air hole 13 to expand the air bag, thereby releasing the locking state of the locking gear 3, ensuring that the user can freely adjust the position of the laser marking head 10. The user can achieve the functions of single-handed adjustment and unlocking / locking during operation, which is more convenient to use.
[0041] Reference Figure 1-Figure 3 The prompt component includes a prompt bin 23, which is fixedly connected to the side wall of the mounting frame 9. Paraffin 25 is provided on one side of the prompt bin 23, and a piston 26 is slidably connected to the other side of the prompt bin 23. A connecting rod 27 is fixedly connected to the middle of the piston 26, and a conductive plate 28 is fixedly connected to the end of the connecting rod 27 away from the piston 26. Electrode sheets 29 are fixedly connected to both sides of the inner wall of the prompt bin 23, and an indicator light 24 is installed on the side of the prompt bin 23 away from the mounting frame 9. The design of the prompt component can monitor the working temperature of the laser marking head 10 in real time. When the temperature is too high, the paraffin 25 in the prompt bin 23 melts, pushing the piston 26 to move, thereby closing the circuit and lighting the indicator light 24, reminding the staff to pay attention to the equipment temperature in time.
[0042] Reference Figure 3 The two electrode sheets 29 are electrically connected to the indicator lights 24, and air holes are provided on the top of the prompting chamber 23. The design of the air holes ensures that the internal gas can flow normally when the temperature changes, and will not affect the work of the prompting component.
[0043] Reference Figure 3A limiting frame 30 is fixedly connected to the middle of the prompting chamber 23, and the limiting frame 30 is located between the piston 26 and the conductive plate 28. The design of the limiting frame 30 ensures the precise movement between the piston 26 and the conductive plate 28, and also avoids excessive movement of the piston 26 when the temperature changes, thereby ensuring the stability and accuracy of the prompting assembly.
[0044] Working principle: When using this device to support the laser marking head 10, in order to meet the requirements of different products, the user can drive the screw 2 to rotate through the driving component, and the rotation of the screw 2 drives the threaded sleeve 8 on the outside to slide up and down on the inside of the two graphite guide rails 21, thereby adjusting the height of the mounting frame 9, and then adjusting the height of the laser marking head 10 to meet the laser marking requirements of different products. At the same time, because the locking assembly will cooperate with the locking gear 3 to lock the screw 2, it will prevent it from rotating and causing the position of the laser marking head 10 to deviate. At the same time, when adjusting the position of the laser marking head 10, the staff needs to press the rubber bag 12 while rotating the handle 6 of the driving assembly. When the rubber bag 12 is pressed, the air pressure inside it will be transmitted to the inside of the air hole 13 through the cavity 11 inside the worm 5, and pass through the air hole 13 to enter the inside of the sealing ring 14. Then the airflow enters the inside of the air bag 16 through the connection of the connecting pipe 17. Then the air bag 16 will expand rapidly and push the latching teeth 18 upward along the inner wall of the limit shell 15. At the same time, the limit shell 15 moves upward to disengage from the locking gear 3, so that the locking gear 3 is out of the locked state, and the spring 19 is also compressed. At this time, the user can rotate the handle 6 to drive the worm 5 to rotate, and the rotation of the worm 5 drives the worm wheel 4 and the locking gear 3 to rotate, and then drives the screw 2 to rotate, so as to achieve the adjustment and expansion of the position of the laser marking head 10. When the handle 6 is released, the rubber bag 12 will rebound and reset, so that the air pressure inside the cavity 11, the sealing ring 14, and the air bag 16 will flow back and maintain balance. At this time, the inflated air bag 16 will slowly shrink to a normal state, and cooperate with the compressed spring 19 to make the locking tooth 18 fall along the limit shell 15 again and engage with the locking gear 3, locking the locking gear 3 again.
[0045] When the laser marking head 10 works continuously for a long time, its temperature will rise rapidly. At this time, the temperature of the laser marking head 10 will be quickly transmitted to the prompt bin 23 through the copper mounting frame 9. As the laser marking head 10 continues to run, the temperature of the prompt bin 23 will gradually rise. When the temperature reaches 40-50°C, the paraffin 25 inside the prompt bin 23 will melt, and the volume of the melted paraffin 25 will increase, and then push the piston 26 to move toward the limit frame 30. At the same time, the movement of the piston 26 will directly push the connecting rod 27 and the conductive plate 28 to move, so that the conductive plate 28 moves and contacts the two electrode sheets 29 on the inner wall of the prompt bin 23, so that the circuit between the two electrode sheets 29 is closed through the contact of the conductive plate 28. At this time, a closed circuit is formed between the indicator light 24, the electrode sheet 29, and the conductive plate 28. At this time, the indicator light 24 emits light and flashes, thereby raising the staff's laser marking head 10 temperature. At the same time, the indicator light 24 is equipped with an independent switch structure, and the staff can choose to turn it on and off according to their needs. Similarly, when the temperature of the prompt chamber 23 returns to room temperature, the melted paraffin 25 will solidify again, and the volume will shrink accordingly, and the inner space will form a negative pressure state. Under the action of the external atmospheric pressure, the piston 26 will also return to its original position. At this time, the conductive plate 28 will also be separated from the two electrode sheets 29. At this time, the circuit is in an open circuit state, and the prompt component stops working, indicating that the working temperature of the laser marking head 10 is in a normal state.
