For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0034] refer to Figure 1-5 , shows a beam height ruler, including a ruler body 1 and a sliding assembly 2, the ruler body 1 is provided with a strip guide hole 11 opened along its length direction, and the ruler body 1 is also provided with a scale 12 located outside the strip guide hole 11; the sliding assembly 2 is slidably arranged in the strip guide hole 11, and the sliding assembly 2 is provided with a horizontally penetrating light hole 21.

[0035] In other words, the position of the sliding component 2 on the strip guide hole 11 can be adjusted according to the height of the laser beam, thereby adjusting the position of the light-through hole 21; when performing equal-height measurement of two laser beams, the height position of the sliding component 2 is first adjusted according to the height of one of the laser beams, so that the laser beam can pass through the light-through hole 21 on the sliding component 2, and then the beam height ruler is used to measure the other laser beam. If the other laser beam can pass through the light-through hole 21, the two laser beams are at the same height, otherwise they are not at the same height; the beam height ruler in this embodiment can flexibly adjust the position of the light-through hole 21 according to the height of the laser beam, quickly determine whether the heights of the two laser beams are at the same height, and has a wider applicability.

[0036] In some specific embodiments, reference Figure 5 The sliding assembly 2 includes a slider 22 and a locking block 23; a guide column 222 is provided on one side of the slider 22, and the guide column 222 is inserted into the strip guide hole 11, and the guide column 222 is provided with an external thread, and the slider 22 is provided with a first hole 221 coaxially arranged with the guide column 222; a second hole 231 with an internal thread is provided on the locking block 23, and the second hole 231 is threadedly connected with the guide column 222, and the first hole 221 and the second hole 231 form the light-through hole 21; the slider 22 and the locking block 23 are respectively located on both sides of the ruler body 1.

[0037] Among them, neither the slider 22 nor the locking block 23 can pass through the strip guide hole 11. When it is necessary to adjust the position of the sliding component 2 on the strip guide hole 11, the locking block 23 can be loosened to increase the distance between the locking block 23 and the slider 22. At this time, the sliding component 2 can be moved along the length direction of the strip guide hole 11; when it is necessary to fix the position of the sliding component 2, the locking block 23 can be tightened so that the locking block 23 and the slider 22 clamp the ruler body 1, making the sliding component 2 unable to move.

[0038] Preferably, the sliding assembly 2 further comprises a spring washer 24, which is arranged between the locking block 23 and the ruler body 1 or between the slider 22 and the ruler body 1. In this embodiment, the spring washer 24 is sleeved on the guide column 222, and the spring washer 24 can exert an elastic force to move the slider 22 and the locking block 23 away from each other. On the one hand, the thread gap between the external thread of the guide column 222 and the internal thread of the second hole 231 can be eliminated, and on the other hand, a certain damping can be provided between the sliding assembly 2 and the ruler body 1, so that when the locking block 23 is in a suitable position on the guide column 222, the sliding assembly 2 can be pushed by an external force (referring to a force other than gravity) and slide along the strip guide hole 11. In the absence of an external force (referring to a force other than gravity), the sliding assembly 2 can maintain a fixed position in the strip guide hole 11. In this way, the user only needs to directly move the sliding assembly 2 during operation, which is more convenient to operate.

[0039] Specifically, in order to read the height position data of the laser beam, refer to Figure 1 and Figure 4 The slider 22 is provided with a horizontally arranged alignment reading line 223 , and the alignment reading line 223 coincides with the center of the first hole 221 .

[0040] Specifically, in order to facilitate the twisting of the locking block 23 , a friction pattern 232 is provided on the outer side wall of the locking block 23 .

[0041] The above scheme is specific. To improve practicality, refer to Figure 1 There are two strip guide holes 11 on the ruler body 1, wherein the scale 12 on the outer side of one strip guide hole 11 is a metric scale 12a, and the scale 12 on the outer side of the other strip guide hole 11 is an English scale 12b.

[0042] In some specific embodiments, reference Figure 1-3 , and also includes a base 3, the lower end of the ruler body 1 is connected to the base 3, and a positioning pin 31 is provided at the bottom of the base 3.

[0043] Specifically, the optical test system is generally set up on an optical platform (commonly known as an optical breadboard), and a plurality of positioning holes are arranged in a vertical and horizontal array on the optical platform to facilitate the rapid positioning and arrangement of optical components on the optical platform; the positioning pin 31 at the bottom of the beam height scale in this embodiment can be used to insert into the positioning hole (not shown) on the optical platform (not shown) to facilitate the positioning of the beam height scale.

[0044] In order to further improve the placement stability of the beam height ruler on the optical platform, refer to Figure 2 and Figure 3A magnetic block 32 may be provided at the bottom of the base 3, and the magnetic block 32 may be used to absorb the optical platform so that the beam height ruler is not easily tipped over.

[0045] In addition, the center of the positioning pin 31 corresponds vertically to the center of the light-through hole 21. Two positioning pins 31 are provided, one positioning pin 31 can correspond to the light-through hole 21 corresponding to the metric scale 12a, and the other positioning pin 31 can correspond to the light-through hole 21 corresponding to the imperial scale 12b; specifically, the direction of a general laser beam will correspond to the positioning sockets arranged horizontally or vertically on the optical platform. By inserting the positioning pin 31 into the corresponding positioning socket, the light-through hole 21 can be quickly made to correspond to the laser beam in the horizontal direction, and then the height position of the light-through hole 21 can be adjusted to make the light-through hole 21 correspond to the laser beam in the vertical direction.

[0046] In some embodiments, reference Figure 3 The lower end of the ruler body 1 is provided with a first connection hole 13, the top of the base 3 is provided with a slot 33 for inserting the ruler body 1, and the two sides of the slot 33 are provided with a second connection hole and a third connection hole 34, respectively, and the second connection hole (not shown) and the third connection hole 34 are coaxially arranged; the base 3 is provided with a locking screw 35, the locking screw 35 passes through the second connection hole, the first connection hole 13 and the third connection hole 34 in sequence, and the locking screw 35 is threadedly connected with the third connection hole 34. Specifically, when the locking screw 35 is tightened, the slot 33 can be tightened, and the slot 33 clamps the lower end of the ruler body 1 to achieve the fixation of the ruler body 1 on the base 3; conversely, the locking screw 35 can be loosened, and the locking screw 35 can be pulled out from the first connection hole 13, the second connection hole and the third connection hole 34, and then the ruler body 1 can be disassembled. In this embodiment, the ruler body 1 and the base 3 are detachably connected, so that they can be replaced separately when part of the structure of the light beam height ruler is damaged. Of course, the ruler body 1 and the base 3 can also be connected in other conventional ways, such as welding, as long as a stable connection between the ruler body 1 and the base 3 is achieved.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
