Abstract
Description
Technical Field
[0001] This utility model relates to the field of beam pointing adjustment for quantum cascade lasers, and particularly to a beam pointing adjustment device for quantum cascade lasers. Background Technology
[0002] In practical applications of quantum cascade lasers, precise beam pointing is crucial for many fields, such as laser communication, laser processing, and precision measurement. To achieve precise beam pointing adjustment, specialized beam pointing adjustment devices are typically used. Existing beam pointing adjustment devices for quantum cascade lasers generally include an adjustment base that can be raised, lowered, and rotated on a support, thereby changing the spatial position of the laser to adjust the beam pointing. However, these adjustment devices pose certain safety hazards in practical use.
[0003] When adjusting the beam direction, it is often necessary to loosen the locking mechanism to allow the adjustment base to move freely on the support. However, in this process, if an accident occurs, such as operator slippage or unexpected vibration to the equipment, the adjustment base may fall due to gravity. Once the adjustment base falls, it may not only damage the quantum cascade laser itself, affecting its normal operation and lifespan, but also cause harm to the surrounding environment and operators. Especially in some applications with extremely high precision requirements, an accidental fall of the adjustment base may cause a significant deviation in the already adjusted beam direction, requiring a lot of time and effort to recalibrate, seriously affecting work efficiency. Utility Model Content
[0004] The main objective of this invention is to propose a beam pointing adjustment device for quantum cascade lasers. This addresses the problem that existing beam pointing adjustment devices for quantum cascade lasers require releasing the locking structure to allow the adjustment base to move freely on the support when adjusting the beam pointing. In such cases, if the operator loses their grip or the equipment experiences unexpected vibrations, the adjustment base may fall due to gravity, damaging the laser itself, affecting normal operation and lifespan, and potentially harming the surrounding environment and personnel. Furthermore, in high-precision applications, this can cause beam pointing deviations, severely impacting work efficiency.
[0005] To address the aforementioned problems, this invention proposes a beam pointing adjustment device for a quantum cascade laser, comprising a cylindrical support and a lifting and rotating adjustment seat sleeved outside the cylindrical support. The lifting and rotating adjustment seat can move up and down and rotate clockwise and counterclockwise outside the cylindrical support. An internally threaded cylinder is inserted into the center of the rear end of the lifting and rotating adjustment seat. The internally threaded cylinder is fixedly connected to the lifting and rotating adjustment seat by welding. A locking screw is threaded into the internally threaded cylinder. A manual knob is fixed to the rear end of the locking screw. The manual knob can drive the locking screw to rotate clockwise and counterclockwise. An adjustment anti-fall device is provided on the top of the lifting and rotating adjustment seat.
[0006] In one embodiment, the adjustable anti-fall device includes a fixed ring, a limiting ring, a support plate A, a support plate B, and rod holes. The fixed ring has a limiting ring at its top end. The fixed ring is sleeved around the top perimeter of the lifting and rotating adjustment seat, and the limiting ring is blocked at the top end of the lifting and rotating adjustment seat. The fixed ring is fixedly connected to the lifting and rotating adjustment seat by screws. The left top end of the limiting ring is welded with support plate A, and the right top end of the limiting ring is welded with support plate B. Support plates A and B are symmetrically arranged on both sides of the cylindrical bracket. Rod holes are provided inside the front and rear sides of the center of support plates A and B.
[0007] In one embodiment, the adjustable fall arrestor further includes a telescopic rod A, a pressing block A, a compression spring, a telescopic rod B, and a pressing block B. The telescopic rod A is inserted into a rod hole inside the support plate A, and the telescopic rod B is inserted into a rod hole inside the support plate B. The right end of the telescopic rod A is connected to the pressing block A, and the left end of the telescopic rod B is connected to the pressing block B. Compression springs are provided between the support plate A and the pressing block A, and between the support plate B and the pressing block B.
[0008] In one embodiment, a plurality of compression springs are respectively sleeved on the outside of telescopic rod A and telescopic rod B. Both telescopic rod A and telescopic rod B can move left and right inside the rod hole, and telescopic rod A and telescopic rod B can respectively drive pressing block A and pressing block B to move synchronously.
[0009] In one embodiment, both the right end of the pressing block A and the left end of the pressing block B are provided with arc-shaped grooves, and the arc-shaped grooves can completely fit against the arc-shaped outer wall of the cylindrical bracket. When both the pressing block A and the pressing block B fit against the outer wall of the cylindrical bracket through the arc-shaped grooves, the multiple compression springs are in a semi-compressed state.
[0010] In one embodiment, the length of the locking screw is greater than the length of the internal threaded cylinder. The clockwise and counterclockwise rotation of the locking screw allows it to move back and forth in the internal threaded cylinder through the action of the thread. When the front end of the locking screw is pressed against the outer wall of the cylindrical bracket, it can lock the height and angle of the lifting and rotating adjustment seat.
[0011] In one embodiment, after the front end of the locking screw disengages from the outer wall of the cylindrical bracket, the lifting and rotating adjustment seat can be raised and lowered and rotated clockwise and counterclockwise outside the cylindrical bracket by holding the manual knob.
[0012] In one embodiment, a mounting plate is fixedly connected to the front end of the lifting and rotating adjustment seat, and a quantum cascade laser body is fixed to the top of the mounting plate by multiple screws. A laser emission window is provided inside the front end of the quantum cascade laser body.
[0013] In one embodiment, a metal fixing sleeve is sleeved and fixed to the bottom of the cylindrical bracket, and a device fixing base is welded to the bottom of the metal fixing sleeve.
[0014] In one embodiment, the device fixing base has mounting slots on both the left and right sides of the center, and a base fixing screw is inserted into each of the two mounting slots. The device fixing base is installed and fixed on the work station by the base fixing screw.
[0015] Beneficial Effects: The technical solution of this utility model adds a novel anti-fall device to the top of the lifting and rotating adjustment seat. When the user manually loosens the locking screw and adjusts the laser direction of the quantum cascade laser by rotating the lifting and rotating adjustment seat, the anti-fall device is symmetrically clamped on the cylindrical bracket by pressure blocks A and B. This prevents the lifting and rotating adjustment seat from falling after the locking screw is loosened, ensuring that the user can accurately and efficiently adjust the laser direction of the quantum cascade laser by rotating the lifting and rotating adjustment seat. The telescopic rods A and B of the anti-fall device can move flexibly within the rod holes. With the elastic action of the compression springs, they can adapt to the slight dimensional differences of the cylindrical bracket and the positional changes of the lifting and rotating adjustment seat during the adjustment process. Multiple compression springs are in a semi-compressed state to provide stable clamping force while preventing excessive pressure from affecting the normal rotation and lifting operation of the lifting and rotating adjustment seat. In addition, the complete fit design of the arc-shaped groove with the arc-shaped outer wall of the cylindrical bracket increases the friction between pressure blocks A and B and the cylindrical bracket, further improving the anti-fall effect and ensuring the stability and safety of the device during the adjustment process.

[0028] This utility model provides, for example Figures 1-5 The illustrated beam pointing adjustment device for a quantum cascade laser includes a cylindrical support 5 and a lifting and rotating adjustment seat 10 sleeved outside the cylindrical support 5. The lifting and rotating adjustment seat 10 can move up and down and rotate clockwise and counterclockwise outside the cylindrical support 5. The cylindrical support 5 serves as the basic support structure of the entire device, providing a support frame for the installation and movement of other components, ensuring the overall stability of the device, and ensuring that components such as the lifting and rotating adjustment seat 10 can move up and down and rotate normally. An internally threaded cylinder 7 is inserted into the center of the rear end of the lifting and rotating adjustment seat 10. The internally threaded cylinder 7 is welded to the lifting and rotating adjustment seat 10. The adjusting seat 10 is fixedly connected, and a locking screw 9 is threaded into the internal threaded cylinder 7. A manual knob 6 is fixed to the rear end of the locking screw 9. The manual knob 6 can drive the locking screw 9 to rotate clockwise and counterclockwise. The core purpose of this device is to achieve flexible adjustment and precise locking of the beam direction of the quantum cascade laser body 12. In terms of structural design, the cylindrical bracket 5 provides a stable support foundation for the entire adjusting device. The lifting and rotating adjusting seat 10, which is sleeved on the outside, can move up and down and rotate clockwise and counterclockwise through a special mechanical structure design. This provides a basis for adjusting the spatial position of the quantum cascade laser body 12.
[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the length of the locking screw 9 is greater than the length of the internal threaded cylinder 7. The locking screw 9 can rotate clockwise and counterclockwise, allowing it to move back and forth within the internal threaded cylinder 7 via the threaded action. When the front end of the locking screw 9 is pressed tightly against the outer wall of the cylindrical bracket 5, it can lock the height and angle of the lifting and rotating adjustment seat 10. The internal threaded cylinder 7 and the lifting and rotating adjustment seat 10 are fixedly connected by welding. The locking screw 9, threaded into the internal threaded cylinder 7, is the key component for achieving the adjustment and locking functions. When the manual knob 6, fixed at the rear end, is manually operated, the manual knob 6 drives the locking screw 9 to rotate clockwise and counterclockwise. Due to the threaded engagement between the locking screw 9 and the internal threaded cylinder 7, the locking screw 9 can move back and forth within the internal threaded cylinder 7. After the front end of the locking screw 9 disengages from the outer wall of the cylindrical bracket 5, holding the manual knob 6 can drive the lifting and rotating adjustment seat 10 to move up and down and clockwise and counterclockwise outside the cylindrical bracket 5. When adjusting the height and angle of the quantum cascade laser body 12, the front end of the locking screw 9 is disengaged from the outer wall of the cylindrical bracket 5. At this time, holding the manual knob 6 will drive the lifting and rotating adjustment seat 10 to move up and down and rotate clockwise and counterclockwise outside the cylindrical bracket 5. In this way, the user can flexibly change the spatial position of the quantum cascade laser body 12 according to actual needs, and thus adjust the direction of the laser emitted by the laser emission window. After the adjustment is completed, in order to ensure the stability of the position of the quantum cascade laser body 12, the manual knob 6 is rotated again, so that the locking screw 9 rotates clockwise and counterclockwise and moves forward in the internal threaded cylinder 7 through the thread action until the front end of the locking screw 9 is pressed against the outer wall of the cylindrical bracket 5, thereby locking the height and angle of the lifting and rotating adjustment seat 10 and ensuring the stability of the beam direction during the operation of the laser.
[0030] like Figure 1 , Figure 2 and Figure 3As shown, a mounting plate 11 is fixedly connected to the front end of the lifting and rotating adjustment seat 10. A quantum cascade laser body 12 is fixed to the top of the mounting plate 11 by multiple screws. The mounting plate 11 provides a mounting platform for the quantum cascade laser body 12, ensuring the relative position of the laser body and the lifting and rotating adjustment seat 10 is fixed, allowing the laser body to change position with the movement of the lifting and rotating adjustment seat 10, thus achieving beam pointing adjustment. A laser emission window is provided inside the front end of the quantum cascade laser body 12. The lifting and rotating adjustment seat 10 can move up and down and rotate clockwise and counterclockwise outside the cylindrical bracket 5. Its front end is fixedly connected to the mounting plate 11, thereby driving the quantum cascade laser body mounted on the mounting plate 11. The laser body 12 changes its spatial position to adjust the laser beam direction in terms of height and angle. A metal fixing sleeve 4 is fixedly fitted to the bottom of the cylindrical bracket 5. A device fixing base 2 is welded to the bottom of the metal fixing sleeve 4. There are mounting slots 1 on both the left and right sides of the center of the device fixing base 2. A base fixing screw 3 is inserted into each of the two mounting slots 1. The device fixing base 2 is installed and fixed in the use position by the base fixing screw 3. The device fixing base 2 is fitted to the bottom of the cylindrical bracket 5 by the metal fixing sleeve 4 and installed in the use position by the base fixing screw 3, providing a stable installation foundation for the entire device and ensuring the overall stability of the device during adjustment and use.
[0031] like Figure 1 , Figure 4 and Figure 5As shown, an adjustment anti-fall device 8 is provided on the outer side of the top of the lifting and rotating adjustment seat 10. The adjustment anti-fall device 8 includes a fixing ring 13, a limiting ring 14, a support plate A15, a support plate B19, and a rod hole 21. The fixing ring 13 is provided with a limiting ring 14 at its top. The fixing ring 13 is sleeved around the top of the lifting and rotating adjustment seat 10, and the limiting ring 14 is blocked at the top of the lifting and rotating adjustment seat 10. The fixing ring 13 is fixedly connected to the lifting and rotating adjustment seat 10 by screws. This connection method ensures that the adjustment anti-fall device 8 and the lifting and rotating adjustment seat 10 form a relatively stable whole. The limiting ring 14 at the top of the fixing ring 13 is blocked at the top of the lifting and rotating adjustment seat 10, which plays the role of positioning and limiting the position of the adjustment anti-fall device 8, so that it can be accurately positioned in the predetermined working position. To provide a foundation for the coordinated operation of subsequent components, a support plate A15 is welded to the top left end of the limiting ring 14, and a support plate B19 is welded to the top right end of the limiting ring 14. The support plates A15 and B19 are symmetrically arranged on both sides of the cylindrical bracket 5. Rod holes 21 are provided inside the front and rear sides of the center of the support plates A15 and B19. The symmetrical structural design of the support plates A15 and B19 not only ensures the overall mechanical balance of the device, but also provides support points for the installation and movement of subsequent components such as telescopic rods and pressure blocks. The rod holes 21 provided inside the front and rear sides of the center of the support plates A15 and B19 are the movement channels of the telescopic rods A16 and B20, which guide and constrain the movement direction of the telescopic rods, ensuring that they can move linearly in the predetermined direction.
[0032] like Figure 1 , Figure 4 and Figure 5As shown, the adjustable fall arrestor 8 also includes a telescopic rod A16, a pressing block A17, a compression spring 18, a telescopic rod B20, and a pressing block B22. The telescopic rod A16 is inserted into the rod hole 21 inside the support plate A15, and the telescopic rod B20 is inserted into the rod hole 21 inside the support plate B19. The right end of the telescopic rod A16 is connected to the pressing block A17, and the left end of the telescopic rod B20 is connected to the pressing block B22. Compression springs 18 are provided between the support plate A15 and the pressing block A17, and between the support plate B19 and the pressing block B22. Multiple compression springs 18 are respectively sleeved on the outside of the telescopic rod A16 and the telescopic rod B20. The device plays a crucial role in providing elastic force. When the device is in normal working condition, that is, when both pressing blocks A17 and B22 are attached to the outer wall of the cylindrical support 5 through the arc-shaped groove, multiple compression springs 18 are in a semi-compressed state. This semi-compressed state gives the compression springs 18 a certain elastic potential energy, enabling them to continuously provide inward elastic force, pushing pressing blocks A17 and B22 to fit tightly against the arc-shaped outer wall of the cylindrical support 5. Telescopic rods A16 and B20 can move left and right inside the rod hole 21, and telescopic rods A16 and B20 can respectively drive pressing blocks A17 and B22 to move synchronously.
[0033] like Figure 1 , Figure 4 and Figure 5 As shown, both the right end of the pressing block A17 and the left end of the pressing block B22 are provided with arc-shaped grooves, which can completely fit against the arc-shaped outer wall of the cylindrical support 5. This fitting design not only increases the contact area between the pressing block and the cylindrical support 5, thereby improving the friction, but also makes the clamping of the pressing block on the cylindrical support 5 more stable and reliable. When both pressing blocks A17 and B22 fit against the outer wall of the cylindrical support 5 through the arc-shaped grooves, the multiple compression springs 18 are in a semi-compressed state. When the user manually loosens the locking screw 9 and adjusts the laser direction of the quantum cascade laser body 12 by rotating the lifting and rotating adjustment seat 10, the locking screw 9 no longer locks the lifting and rotating adjustment seat 10. At this time, the adjustment is unblocked. The drop device 8 begins to function. Under the elastic force of the compression spring 18, the pressing blocks A17 and B22 are tightly clamped onto the cylindrical bracket 5 through the arc-shaped groove, forming a stable support structure. Even after the locking screw 9 is loosened, the lifting and rotating adjustment seat 10 will not fall when subjected to external forces such as gravity, effectively ensuring the safety and stability of the device during adjustment. At the same time, the telescopic rods A16 and B20 can move adaptively within the rod hole 21 to adapt to the possible dimensional tolerances of the cylindrical bracket 5 and the slight positional changes of the lifting and rotating adjustment seat 10 during adjustment, ensuring that the pressing blocks can always maintain a good fit with the cylindrical bracket 5 and continuously perform the anti-fall function.
[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
