Description

Technical Field

[0001] The utility model relates to the technical field of beam expanders, in particular to a beam expander bracket which is convenient for stable adjustment. Background Art

[0002] A beam expander is a lens component that can change the diameter and divergence angle of a laser beam. When using a beam expander, it is generally necessary to adjust the angle of the beam expander to adapt to different usage environments. At this time, a beam expander bracket that is easy to adjust stably is needed.

[0003] According to a disclosed adjustable beam expander bracket (Announcement No.: CN213750454U), compared with the traditional beam expander bracket, the above application can be rotated, can assist in clamping, and can provide dust protection to a certain extent, thereby improving the practicality of the beam expander bracket.

[0004] However, during actual use of the above-mentioned device, it is difficult to limit the angle of each adjustment of the beam expander, and the angle after rotation cannot be fixed. When fine adjustment is required, it is difficult for the device to control the angle of the beam expander for close movement and it cannot be fixed after moving into position. When encountering vibration, the angle of the beam expander may change, which reduces the effectiveness of the beam expander. In view of this, we propose a beam expander bracket that is easy to adjust stably. Utility Model Content

[0009] A return spring is fixedly connected to the outer wall of the inclined plate, the outer wall of the inclined plate is fixedly connected to a pressure rod, and one end of the pressure rod away from the inclined plate is fixedly connected to a friction plate.

[0010] Preferably, the telescopic end of the telescopic block is consistent in size with the gap between the teeth of the gear, and a spring is provided inside the telescopic block, so that when adjusting the pitch angle of the collimator, the rotating shaft is rotated to rotate the gear and the teeth of the gear contact the telescopic block so that the telescopic block is squeezed. After the teeth of the gear leave the telescopic block, the telescopic block is reset by the spring and stuck between the teeth of the gear, fixing the pitch angle, so that the collimator can adjust more angles and the angle can be fixed.

[0011] Preferably, the outer wall of the inclined plate is fixedly connected to a limit block, and one end of the limit block close to the friction plate is fixedly connected to a return spring, and the other end of the return spring is fixedly connected to the inner wall of the fixed shell, so that when the bolt rotates to drive the C-shaped plate to drive the inclined block to leave the inclined plate, the inclined plate is reset by the return spring, so that the friction plate leaves the turntable, thereby allowing the rotating shell to rotate freely.

[0012] Preferably, a limiting groove is provided on the outer wall of the fixed shell, and the limiting plate is rotatably connected to the inner wall of the limiting groove, so that when the rotating shell rotates on the outer wall of the fixed shell, the rotating shell is not easy to slip off the inner wall of the fixed shell, thereby making the fixation of the beam expander more stable.

[0013] Preferably, inclined blocks and inclined plates are provided at both upper and lower ends of the C-shaped plate, and the friction plate is made of a rubber plate, so that the friction force between the friction plate and the turntable is greater, thereby making the deceleration effect of the friction plate on the turntable more obvious.

[0015] Compared with the prior art, the present invention provides a beam expander bracket that is easy to adjust stably and has the following beneficial effects:

[0016] 1. The collimator bracket, which is easy to stably adjust, rotates the rotating shell by rotating the push block. When the shell is rotated to the approximate position, the bolt is tightened, so that the bolt drives the C-shaped plate to move through the collar, drives the inclined block to push the inclined plate downward, so that the friction plate presses the turntable. The friction plate presses the turntable to increase the force required to rotate the turntable, so that the rotating angle of the rotating shell with the same force is smaller, so that the rotation angle of the collimator can be adjusted more finely, and further tightening the bolt can fix the rotation angle of the collimator.

[0017] 2. The beam expander bracket, which is easy to stably adjust, rotates the shaft to rotate the gear, thereby retracting the clamping block. When the gear stops rotating, the clamping column gear fixes the gear, thereby fixing the pitch angle of the beam expander. This allows the beam expander to be adjusted to more angles while also fixing the angle to prevent vibration from causing angle changes and reducing the accuracy of laser measurement.

[0025] In one embodiment of the present utility model, the gear 101 is fixedly connected to the inner wall of the rotating shaft 7, the inner wall of the rotating shell 4 is fixedly connected to the telescopic block 102, the outer wall of the rotating shell 4 is fixedly connected to the transmission rod 103, and the outer wall of the lower end of the transmission rod 103 is fixedly connected to the turntable 104.

[0026] In one embodiment of the present utility model, a bolt 105 passes through and is threadedly connected to the outer wall of the fixed shell 3. A ring 106 is sleeved on the end of the bolt 105 close to the turntable 104. The outer wall of the ring 106 is rotatably connected to a C-shaped plate 107. The end of the C-shaped plate 107 is fixedly connected to a bevel block 108. The outer wall of the bevel block 108 is fitted with a bevel plate 109.

[0027] In one embodiment of the present invention, the return spring 1010 is fixedly connected to the outer wall of the inclined plate 109 , the outer wall of the inclined plate 109 is fixedly connected to a pressure rod 1011 , and the end of the pressure rod 1011 away from the inclined plate 109 is fixedly connected to a friction plate 1012 .

[0028] In addition, the telescopic end of the telescopic block 102 is consistent in size with the gap between the teeth of the gear 101, and a spring is provided inside the telescopic block 102, so that when adjusting the pitch angle of the beam expander, the rotating shaft 7 is rotated to rotate the gear 101 and the teeth of the gear 101 contact the telescopic block 102 so that the telescopic block 102 is squeezed. After the teeth of the gear 101 leave the telescopic block 102, the telescopic block 102 is reset by the spring and stuck between the teeth of the gear 101, fixing the pitch angle, so that the beam expander can adjust more angles and the angle can be fixed, preventing vibration from causing angle changes and reducing the accuracy of laser measurement.

[0029] In an embodiment of the present utility model, the outer wall of the inclined plate 109 is fixedly connected to a limit block, and one end of the limit block close to the friction plate 1012 is fixedly connected to a return spring 1010, and the other end of the return spring 1010 is fixedly connected to the inner wall of the fixed shell 3. When the bolt 105 rotates to drive the C-shaped plate 107 to drive the inclined block 108 to leave the inclined plate 109, the inclined plate 109 is reset by the return spring 1010, so that the friction plate 1012 leaves the turntable 104, so that the rotating shell 4 can rotate freely, which is convenient for adjusting the rotation angle of the collimator.

[0030] In an embodiment of the present utility model, a limiting groove is provided on the outer wall of the fixed shell 3, and the limiting plate 6 is rotatably connected to the inner wall of the limiting groove, so that when the rotating shell 4 rotates on the outer wall of the fixed shell 3, the rotating shell 4 is not easy to slip off the inner wall of the fixed shell 3, thereby making the fixation of the collimator more stable and preventing the collimator from falling and being damaged when adjusting the angle of the collimator.

[0031] In an embodiment of the present utility model, inclined blocks 108 and inclined plates 109 are provided at the upper and lower ends of the C-shaped plate 107, and the friction plate 1012 is made of a rubber sheet, so that the friction force between the friction plate 1012 and the turntable 104 is greater, thereby making the deceleration effect of the friction plate 1012 on the turntable 104 more obvious, so that when the friction plate 1012 presses the turntable 104, the rotation angle of the rotating shell 4 can be more accurately adjusted.

[0032] In an embodiment of the present invention, the slope of the inclined surface of the inclined block 108 is opposite to the slope of the inclined surface of the inclined plate 109, and the inclined surface of the inclined block 108 fits the inclined surface of the inclined plate 109. The height of the inclined block 108 is consistent with the height of the inclined plate 109, and the height of the inclined block 108 is consistent with the distance between the friction plate 1012 and the turntable 104, so that the inclined block 108 can better push the inclined plate 109 to move downward, and when the inclined block 108 descends, the friction plate 1012 can press the turntable 104, so that the linear beam expander can be adjusted more accurately.

[0033] In the present invention, when in use, the gear 101 is rotated by rotating the shaft 7, so that the teeth of the gear 101 contact the telescopic block 102 to shrink the telescopic block 102. After the teeth of the gear 101 leave the telescopic block 102, the telescopic block 102 is reset and clamps the column gear 101 to fix the gear 101, thereby fixing the pitch angle of the beam expander, so that the beam expander can adjust more angles and the angle can also be fixed to prevent vibration from causing angle changes and reducing the accuracy of laser measurement. Then, the push block 5 is rotated to rotate the rotating shell 4. When it rotates to the approximate position, the bolt 105 is tightened, so that the bolt 105 drives the C-type plate 107 to move through the ring 106. The C-type plate The movement of 107 causes the inclined block 108 to push the inclined plate 109 downward, so that the inclined plate 109 pushes the pressure rod 1011 to make the friction plate 1012 press the turntable 104. The turntable 104 is connected to the rotating shell 4 through the transmission rod 103. The friction plate 1012 presses the turntable 104 to increase the force required to rotate the turntable 104, thereby making the force required to rotate the rotating shell 4 greater, and making the angle that the rotating shell 4 can rotate with the same force smaller, so that the angle of rotation of the collimator can be more finely adjusted. At the same time, further tightening the bolt 105 can further increase the friction between the turntable 104 and the friction plate 1012 until the turntable 104 is completely fixed, thereby making the angle of rotation of the collimator fixed.

[0034] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
