Description

Technical Field

[0001] This invention relates to the field of laser base technology, specifically a laser base for supporting lasers. Background Technology

[0002] Semiconductor lasers, also known as laser diodes, are light sources that generate laser light by utilizing the recombination process of charge carriers in semiconductor materials. The laser base is an important component of the laser system, used to support and fix the main structure of the laser and provide a stable foundation to ensure the accuracy and stability of the laser.

[0003] Patent publication number CN213018581U relates to a rotating base for a large spherical laser, including a laser body and a base. A support rod is fixedly connected to the lower middle part of the laser body, and the support rod is slidably connected to a support tube. A connecting groove is formed inside the base, and a receiving groove is formed inside the base near the lower end of the connecting groove. The receiving groove and the connecting groove are connected. The lower end of the support tube passes through the connecting groove and is fixedly connected to a connecting block. First rollers are fixedly connected to both sides of the lower end of the connecting block. An auxiliary groove is formed inside the base. The beneficial effects of this patent are: through the structure of the connecting rod, slider, second roller, connecting block and first roller, the laser at the upper end of the support rod can be adjusted, making the laser easy to adjust during use, avoiding the trouble of multiple disassemblies, increasing the service life of the laser. Furthermore, the threaded rod, threaded groove, limiting frame and throttle structure can fix the laser after angle adjustment on the base, preventing rotation during use.

[0004] The aforementioned patent allows for easy adjustment during use, avoiding the hassle of multiple disassemblies and increasing the lifespan of the laser. Furthermore, the threaded rod, threaded groove, limiting frame, and throttle structure can fix the laser, after angle adjustment, on the base, preventing rotation during use. However, the laser requires adjustment of its working height and angle during use. Damage to the base supporting the laser, causing it to move downwards rapidly, can damage the laser. Additionally, rapid angle adjustments can also easily damage the laser. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a laser base for supporting lasers, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a laser base for supporting a laser, comprising a support base, a connecting seat rotatably mounted on the top of the support base, a lifting device fixedly mounted on the top of the connecting seat, an output plate fixedly mounted on the output end of the lifting device, a pushing device rotatably mounted on the top of the support base, the output end of the pushing device being rotatably connected to the connecting seat, and a support device provided between the support base and the mounting plate; wherein, the support device comprises a fixed plate, an L-shaped cylinder, a sealing plate, a connecting rod, a hollow frame, a swing plate, an L-shaped plate, and an elastic plate, the fixed plate being fixedly mounted on the surface of the connecting seat, and the L-shaped cylinder being fixedly mounted on the connecting seat. The sealing plate is slidably installed inside the L-shaped cylinder at the top of the fixed plate. The connecting rod is fixedly installed on the top of the sealing plate. The hollow frame is fixedly installed at the bottom of the mounting plate. The surface of the hollow frame is provided with an exhaust port. The swing plate is rotatably installed at the bottom of the mounting plate. The L-shaped plate is slidably installed on the top of the L-shaped cylinder. The elastic plate is fixedly installed on the left side of the L-shaped plate. The surface of the connecting rod is provided with a groove. The L-shaped cylinder is connected to the interior of the hollow frame through a pipe. When the mounting plate moves downward quickly, it will drive the connecting rod and the sealing plate to move downward. When the sealing plate moves downward, it will squeeze the air inside the L-shaped cylinder into the interior of the hollow frame through the pipe. The air inside the hollow frame will be discharged through the exhaust port.

[0007] According to the above technical solution, a torsion spring is provided between the swing plate and the mounting plate, and a spring is provided between the L-shaped plate and the L-shaped cylinder. The elastic force of the spring will drive the L-shaped plate to reset. The top of the L-shaped plate can extend and retract while being elastic. The extension end of the top of the L-shaped plate is fixed to the bottom of the mounting plate.

[0008] According to the above technical solution, a piston rod is slidably installed inside the L-shaped cylinder, and a fixed frame is fixedly installed on the top of the support base. The fixed frame is hinged to one end of the linkage rod, and the other end of the linkage rod is hinged to the piston rod. When the mounting plate rotates, the linkage rod will pull the piston rod to move, which can reduce the rotation speed of the mounting plate and the laser, and avoid damage to the laser caused by excessive rotation speed of the connecting seat and the mounting plate.

[0009] According to the above technical solution, an L-shaped tube is fixedly installed on the surface of the L-shaped cylinder, and the exhaust port is in contact with the swing plate. The L-shaped tube can connect the free parts of the L-shaped cylinder together, so that when the piston rod moves to the left inside the L-shaped cylinder, the piston rod will squeeze the air on the left side of the piston rod to re-enter the internal pipe of the L-shaped cylinder.

[0010] According to the above technical solution, the surface of the hollow frame is provided with an auxiliary support device to prevent damage to the laser from rapid downward movement. The surface of the fixed plate is provided with an anti-tipping device. The auxiliary support device includes a movable plate, a push rod, a forked plate, a mounting frame, a placement frame, and a horizontal plate. An increase in air pressure inside the hollow frame will push the movable plate upward. The upward movement of the movable plate will drive the push rod upward. The upward movement of the push rod will drive the forked plate upward. The upward movement of the forked plate will drive the horizontal plate upward. The movable plate is slidably installed inside the hollow frame. The push rod is fixedly installed on the top of the movable plate. The top of the mounting plate has a cavity. The forked plate slides through the bottom of the cavity. The mounting frame is fixedly installed on the top of the mounting plate. The placement frame is slidably installed inside the mounting frame. The bottom of the placement frame is fixedly installed with a horizontal plate by a spring clip.

[0011] According to the above technical solution, the horizontal plate is in contact with the forked plate, and a second spring is provided between the movable plate and the hollow frame. The elastic force of the second spring will drive the movable plate to reset.

[0012] According to the above technical solution, the anti-tipping device includes a bending rod, a circular block, an elastic telescopic rod, a concave plate, a limiting frame, and a circular frame. The connecting seat and the L-shaped cylinder will rotate excessively. When the L-shaped cylinder rotates excessively, the piston rod will push the bending rod to move outward of the L-shaped cylinder. The movement of the bending rod will drive the circular block to move. When the circular block moves, it will contact the inclined surface of the concave plate, causing the circular block to push the concave plate downward. The bending rod slides through the inner and outer walls of the L-shaped cylinder. The circular block is fixedly installed on the surface of the bending rod. The elastic telescopic rod is fixedly installed at the bottom of the fixed plate. The concave plate is fixedly installed at the free end of the elastic telescopic rod. The limiting frame is slidably installed at the bottom of the fixed plate. The circular frame is slidably installed at the bottom of the connecting seat. The surface of the circular frame is provided with a slot.

[0013] According to the above technical solution, a No. 3 spring is provided between the bending rod and the L-shaped cylinder, a No. 4 spring is provided between the limiting frame and the fixing plate, and a return spring is provided between the circular frame and the connecting seat. The elastic force of the No. 3 spring will drive the bending rod to return to its original position.

[0014] This invention provides a laser base for supporting a laser. It has the following advantages: (1) The invention can support the laser by means of a support base, a connecting seat, a lifting device and a mounting plate, so as to avoid the laser being placed randomly and affecting its use, and at the same time, it can protect the laser.

[0015] (2) In this invention, when the lifting device is damaged and the mounting plate moves downward rapidly, the rapid downward movement of the mounting plate will drive the connecting rod and the sealing plate to move downward. The sealing plate will squeeze the air inside the L-shaped cylinder into the hollow frame. The exhaust port on the surface of the hollow frame will reduce the speed of gas discharge, thereby reducing the speed of the mounting plate moving downward. At the same time, the rapid exhaust from the exhaust port will blow the swing plate to rotate. The swing plate will push the L-shaped plate and the elastic plate to move. The elastic plate will insert into the groove to further reduce the descent speed of the mounting plate, avoiding damage to the laser caused by the rapid descent of the mounting plate to the bottom. At the same time, when the mounting plate rotates, the linkage rod will pull the piston rod to move, which can reduce the rotation speed of the mounting plate and the laser.

[0016] (3) In this invention, when the mounting plate moves downward quickly, the exhaust port cannot discharge the gas in time. The increased air pressure inside the hollow frame will push the movable plate and the push rod to move upward. The push rod moving upward will push the forked plate and the horizontal plate to move upward. The horizontal plate moving upward will push the spring and the placement frame to move upward. This will lift the placement frame and the laser. When the mounting plate moves to the bottom, the spring can buffer the placement frame and the spring, preventing the laser from moving directly to the bottom with the mounting plate and causing an impact. When the mounting plate does not move downward quickly, the bottom of the placement frame will fit inside the mounting frame and will not affect the stability of the placement frame.

[0017] (4) When the connecting seat and mounting plate of the device are damaged and rotated excessively to the left and right, the piston rod will push the bending rod to move. When the bending rod moves, the circular block will push the concave plate to move downward. When the concave plate moves downward, it will release the limit on the limit frame. When the limit frame moves, it will release the limit on the circular frame. When the circular frame moves downward, the reverse force will support the connecting seat and mounting plate, preventing the mounting plate from tilting and damaging the laser.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-7 One embodiment of the present invention is as follows: a laser base for supporting a laser includes a support base 1, a connecting seat 2 rotatably mounted on the top of the support base 1, a lifting device 3 fixedly mounted on the top of the connecting seat 2, an mounting plate 4 fixedly mounted on the output end of the lifting device 3, a pushing device 5 rotatably mounted on the top of the support base 1, the output end of the pushing device 5 being rotatably connected to the connecting seat 2, and a support device provided between the support base 1 and the mounting plate 4; wherein, the support device includes a fixed plate 6, an L-shaped cylinder 7, a sealing plate 8, a connecting rod 9, a hollow frame 10, a swing plate 11, an L-shaped plate 12, and an elastic plate 13, the fixed plate 6 being fixedly mounted on the surface of the connecting seat 2, the L-shaped cylinder 7 being fixedly mounted on the top of the fixed plate 6, and the sealing plate 8 being slidably mounted inside the L-shaped cylinder 7. The connecting rod 9 is fixedly installed on the top of the sealing plate 8, the hollow frame 10 is fixedly installed on the bottom of the mounting plate 4, the surface of the hollow frame 10 is provided with an exhaust port, the swing plate 11 is rotatably installed on the bottom of the mounting plate 4, the L-shaped plate 12 is slidably installed on the top of the L-shaped cylinder 7, the elastic plate 13 is fixedly installed on the left side of the L-shaped plate 12, the surface of the connecting rod 9 is provided with a groove, the L-shaped cylinder 7 is connected to the interior of the hollow frame 10 through a pipe, the exhaust port on the surface of the hollow frame 10 will reduce the speed of gas discharge, thereby reducing the downward movement speed of the mounting plate 4, and at the same time the rapid exhaust from the exhaust port will blow the swing plate 11 to rotate, the swing plate 11 will push the L-shaped plate 12 and the elastic plate 13 to move, the elastic plate 13 will insert into the interior of the groove to further reduce the downward speed of the mounting plate 4.

[0022] A torsion spring is provided between the swing plate 11 and the mounting plate 4, and a spring is provided between the L-shaped plate 12 and the L-shaped cylinder 7. The spring force of the L-shaped plate 12 will drive the L-shaped plate 12 to reset. The top of the L-shaped plate 12 can extend and retract and is elastic. The extension end of the top of the L-shaped plate 12 is fixed to the bottom of the mounting plate 4.

[0023] The L-shaped cylinder 7 has a piston rod 15 slidably installed inside. The top of the support base 1 has a fixed bracket 14. The fixed bracket 14 is hinged to one end of the linkage rod 16, and the other end of the linkage rod 16 is hinged to the piston rod 15. When the mounting plate 4 rotates, the linkage rod 16 will pull the piston rod 15 to move. At the same time, it can reduce the rotation speed of the mounting plate 4 and the laser, and avoid damage to the laser caused by the excessive rotation speed of the connecting seat 2 and the mounting plate 4.

[0024] An L-shaped pipe is fixedly installed on the surface of the L-shaped cylinder 7. The exhaust port is in contact with the swing plate 11. The L-shaped pipe can connect the free parts of the L-shaped cylinder 7 together. When the piston rod 15 moves to the left inside the L-shaped cylinder 7, the piston rod 15 will squeeze the air on the left side of the piston rod 15 and re-enter the internal pipe of the L-shaped cylinder 7.

[0025] In this embodiment, when the lifting device 3 is damaged and cannot support the mounting plate 4, the weight of the mounting plate 4 and the laser will cause the mounting plate 4 to move downwards rapidly. This rapid downward movement of the mounting plate 4 will cause the connecting rod 9 and the sealing plate 8 to move downwards. When the sealing plate 8 moves downwards, it will compress the air inside the L-shaped cylinder 7 and allow it to enter the hollow frame 10 through the pipe. The air inside the hollow frame 10 will be discharged through the exhaust port. The smaller exhaust port will reduce the exhaust speed inside the hollow frame 10. The slow discharge of air from the hollow frame 10 and the L-shaped cylinder 7 will reduce the descent speed of the sealing plate 8, the connecting rod 9, and the mounting plate 4. The swing plate 11, the L-shaped plate 12, and the elastic plate 13 are all made of lightweight materials. When the air pressure ejected from the exhaust port is too high, it will blow the swing plate 11. When the swing plate 11 rotates, it contacts the L-shaped plate 12 and pushes the L-shaped plate 12 to move. The movement of the L-shaped plate 12 will drive the elastic plate 13 to move. When the elastic plate 13 moves, it will insert into the inside of the groove, which will further reduce the descent speed of the connecting rod 9 and the mounting plate 4. The angle of the connecting seat 2, the lifting device 3 and the mounting plate 4 will be adjusted by the pushing device 5. The rotation of the connecting seat 2 will drive the fixed plate 6 and the L-shaped cylinder 7 to rotate. When the L-shaped cylinder 7 rotates, the fixed frame 14 and the linkage rod 16 will pull the piston rod 15 to move. When the piston rod 15 moves, it will also squeeze the air inside the L-shaped cylinder 7 and enter the hollow frame 10 through the pipe, thereby achieving the effect of reducing the rotation speed of the connecting seat 2.

[0026] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the surface of the hollow frame 10 is provided with an auxiliary support device to prevent damage to the laser from rapid downward movement, and the surface of the fixed plate 6 is provided with an anti-tipping device. The auxiliary support device includes a movable plate 171, a push rod 172, a forked plate 173, a mounting frame 174, a placement frame 175, and a horizontal plate 176. When the mounting plate 4 moves to the bottom, the spring can buffer the placement frame 175 and the spring. When the mounting plate 4 does not move downward rapidly, the bottom of the placement frame 175 will fit against the inside of the mounting frame 174 and will not affect the stability of the placement frame 175. The movable plate 171 is slidably installed inside the hollow frame 10, and the push rod 172 is fixedly installed on the top of the movable plate 171. A cavity is opened at the top of the mounting plate 4, and the forked plate 173 slides through the bottom of the cavity. The mounting frame 174 is fixedly installed on the top of the mounting plate 4, and the placement frame 175 is slidably installed inside the mounting frame 174. The bottom of the placement frame 175 is fixedly installed with a horizontal plate 176 by a spring.

[0027] The horizontal plate 176 contacts the forked plate 173. A second spring is provided between the movable plate 171 and the hollow frame 10. The elastic force of the second spring will drive the movable plate 171 to reset.

[0028] The anti-tipping device includes a bending rod 181, a circular block 182, an elastic telescopic rod 183, a concave plate 184, a limiting frame 185, and a circular frame 186. When the limiting frame 185 moves, it releases the limiting effect on the circular frame 186. When the circular frame 186 moves downward, the reverse force will support the connecting seat 2 and the mounting plate 4, preventing the mounting plate 4 from tipping over and damaging the laser. The bending rod 181 slides through the inner and outer walls of the L-shaped cylinder 7. The circular block 182 is fixedly installed on the surface of the bending rod 181. The elastic telescopic rod 183 is fixedly installed on the bottom of the fixed plate 6. The concave plate 184 is fixedly installed on the free end of the elastic telescopic rod 183. The limiting frame 185 is slidably installed on the bottom of the fixed plate 6. The circular frame 186 is slidably installed on the bottom of the connecting seat 2. The surface of the circular frame 186 is provided with a slot.

[0029] A No. 3 spring is installed between the bending rod 181 and the L-shaped cylinder 7, a No. 4 spring is installed between the limit frame 185 and the fixed plate 6, and a return spring is installed between the circular frame 186 and the connecting seat 2. The elastic force of the No. 3 spring will drive the bending rod 181 to return to its original position.

[0030] When this embodiment is working: when the air inside the hollow frame 10 cannot be discharged in time, the air pressure inside the hollow frame 10 will gradually increase. The increase in air pressure inside the hollow frame 10 will push the movable plate 171 to move upward. The upward movement of the movable plate 171 will drive the push rod 172 to move upward. The upward movement of the push rod 172 will push the forked plate 173 to move upward. The upward movement of the forked plate 173 will push the horizontal plate 176 to move upward. The upward movement of the horizontal plate 176 will push the spring and the placement frame 175 to move upward. The upward movement of the placement frame 175 will apply an upward force to the laser. The bottom of the placement frame 175 will disengage from the mounting frame 174. When the pushing device 5 is damaged and cannot support the connecting seat 2, the connecting seat 2 and the L-shaped cylinder 7 will rotate excessively. When the L-shaped cylinder 7 rotates excessively, the piston rod 15 will push the bent rod 181 to move outward from the L-shaped cylinder 7. The movement of the bent rod 181 will drive the circular block 182 to move. When the circular block 182 moves, it will contact the inclined surface of the concave plate 184, causing the circular block 182 to push the concave plate 184 downward. When the concave plate 184 moves downward, it will disengage from the limiting frame. The contact of 185 causes the concave plate 184 to release its restriction on the limiting frame 185. Under the elastic force of the fourth spring, the limiting frame 185 will move away from the circular frame 186. The movement of the limiting frame 185 will disengage from the slot and release its restriction on the circular frame 186. Under the action of the return spring, the circular frame 186 will move downward. The downward movement of the circular frame 186 will contact the support base 1. The force exerted by the support base 1 on the circular frame 186 will push the connecting seat 2 to stand up, preventing the connecting seat 2 and the mounting plate 4 from tipping over.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
