[0048] See Figure 1 At least one embodiment of the present application proposes a three-degree-of-freedom adjustable fixing bracket, which includes a base 100, a mounting member 200, a first connecting member 300 and a first adjustment component. The base 100 is used to rotate and connect the member to be mounted, and the member to be mounted can rotate around a first direction relative to the base 100. The mounting member 200 is connected to the base 100 in a sliding and rotating composite connection. The base 100 can slide relative to the mounting member 200 along a second direction, and the base 100 can rotate relative to the mounting member 200 about the second direction. The first direction intersects with the second direction. The mounting member 200 is movably connected to the first connecting member 300. The first adjustment component is connected between the mounting member 200 and the first connecting member 300. After the mounting member 200 slides along the first direction on the first connecting member 300 through the first adjustment component, it is fixed by the first adjustment component.
[0049] According to the three-degree-of-freedom adjustable fixing bracket of the embodiment of the present application, when the object to be mounted is a target light, the target light is rotatably connected to the base 100, and the base 100 can rotate or slide on the mounting member 200. According to the needs of different measurement angles and distances, the position and angle of the target light can be adjusted in three degrees of freedom, ensuring that the target light remains stable during the measurement process and is not affected by external interference. The position of the target light can also be finely adjusted, improving measurement accuracy and simplifying operation.
[0050] See Figure 2In some embodiments, the first direction is perpendicular to the second direction. The first direction is the Z direction in the figure, that is, the vertical direction; the second direction is the X direction in the figure, that is, the horizontal direction.
[0051] Specifically, the fixed bracket provides three independent adjustment dimensions for the target light through the coordinated action of the base 100, the mounting member 200, the first connecting member 300 and the first adjustment assembly. A rotational connection design is adopted between the base 100 and the target light, so that the target light can rotate freely around a first direction. For example, an axis perpendicular to the ground. This structure allows the operator to flexibly adjust the horizontal angle of the target light according to measurement requirements, such as when aligning measuring points at different positions in bridge inspections. This rotational connection is achieved through precise shaft-hole matching or roller groove structure, which can not only ensure the smoothness of rotation, but also maintain stability through friction or locking device after adjustment, avoiding angle deviation due to external vibration.
[0052] The sliding and rotating composite connection between the mounting member 200 and the base 100 is the core of achieving the other two degrees of freedom. The base 100 can slide in a second direction, such as horizontally, to adjust the horizontal distance of the target light to meet the needs of different measurement distances. At the same time, the base 100 can also rotate around the axis of the mounting member 200, allowing fine-tuning of the angle of the target light within the horizontal plane. The sliding and rotation in the second direction are independent of each other, and the second direction intersects perpendicularly with the first direction, forming a two-dimensional adjustment plane in space. Combined with the rotation of the target light in the first direction, these three degrees of freedom are achieved.
[0053] See Figure 2 and Figure 3 In some embodiments, an upward cylindrical protrusion 120 is provided on the base 100, and the protrusion 120 is used to be rotatably connected to a cylindrical groove (not shown in the figure) at the bottom of the target light.
[0054] In some embodiments, a first connecting hole 110 is provided on the base 100. The mounting member 200 is configured as a tube body axially arranged along the second direction, and the base 100 is slidably and rotatably connected to the outer wall of the mounting member 200 through the first connecting hole 110. The socket connection between the base 100 and the mounting member 200 facilitates quick assembly and disassembly. Specifically, the first connecting hole 110 on the base 100 is a circular or quasi-circular through hole, and its aperture is slightly larger than the outer diameter of the mounting member 200, forming a clearance fit. The axis of the first connecting hole 110 is aligned with the axis of the mounting member 200, ensuring that the base 100 can slide along the axial direction of the mounting member 200, that is, the second direction.
[0055] The base 100 is mounted on the outer wall of the mounting member 200 through the first connecting hole 110. The base 100 can slide freely along the axial direction of the mounting member 200 to adjust the horizontal distance, such as moving the target light closer to or farther away from the object being measured. The base 100 can rotate around the axis of the mounting member 200, that is, the first connecting hole 110 rotates around the outer wall of the tube body, to achieve fine-tuning of the angle of the base 100 in the horizontal plane, such as deflecting the target light left or right. Sliding and rotation can be performed simultaneously or independently without interfering with each other, forming two independent degrees of freedom. Through the above arrangement, the target light can flexibly adjust its position and angle in three-dimensional space to meet complex measurement requirements such as aligning measurement points at different heights, distances, and angles.
[0056] See Figure 4 In some embodiments, a limit plate 210 is provided at the end of the mounting member 200. When the base 100 slides along the second direction to the end of the mounting member 200, it abuts against the limit plate 210. The limit plate 210 prevents the base 100 from sliding excessively and falling off, ensuring the safety of the equipment during measurement and preventing the target light from accidentally falling off when moving.
[0057] It can be understood that the sliding and rotating composite connection between the mounting member 200 and the base 100 can also be other structures, such as a ball joint and a slide. For example, the base 100 is connected to the mounting member 200 through a ball joint, and the ball joint allows 360° rotation; at the same time, the mounting member 200 is provided with a slide, and the base 100 is connected to the slide through a slider, allowing sliding along the direction of the slide.
[0058] See Figure 2 、 Figure 4 and Figure 5 In some embodiments, the first adjustment assembly includes a first adjustment slot 310, a first adjustment plate 220, and a first adjustment screw 400. The first adjustment slot 310 is disposed on the first connecting member 300 along a first direction. The first adjustment plate 220 is fixedly mounted on the mounting member 200. The first adjustment screw 400 is slidably connected within the first adjustment slot 310 and is threadedly connected to the first adjustment plate 220. A first double-layer nut 410 is threadedly connected to the first adjustment screw 400.
[0059] Through the above-mentioned arrangement, the first adjustment component realizes the positioning and fixation of the mounting member 200 on the first connecting member 300 through a mechanical structure. When the mounting member 200 needs to slide along the first direction on the first connecting member 300, the operator can precisely control the position of the mounting member 200 through the cooperation of the first adjustment screw 400, the first adjustment slot 310 and the first double-layer nut 410. The mounting member 200 slides up and down in the first adjustment slot 310 through the first adjustment screw 400. After adjusting to the target position, the mounting member 200 is fixed by tightening the first double-layer nut 410 and the first gasket to ensure that the entire bracket will not be displaced due to external forces during the measurement process. This modular design not only simplifies the operating process, but also improves the stability of the bracket through the mechanical locking mechanism, reducing the errors and time-consuming problems in traditional manual adjustment.
[0060] See Figure 4 In some embodiments, a plurality of reinforcing ribs 230 are connected between the first adjustment plate 220 and the mounting member 200 to improve the connection stability.
[0061] See Figure 2 and Figure 6 In some embodiments, the three-degree-of-freedom adjustable fixed bracket also includes a second adjustment component, the second adjustment component includes a second connecting member 500 and a second adjusting screw 600, the second adjusting screw 600 is arranged along the second direction, one end of the second adjusting screw 600 is fixed to the second connecting member 500, and the other end passes through the first adjustment slot 310, and the first adjustment plate 220 slides along the second direction on the second adjusting screw 600 through the first adjustment slot 310.
[0062] In some embodiments, a second gasket 610 is provided on the second adjusting screw 600, and a second double-layer nut 620 is threadedly connected to the second adjusting screw 600. The second double-layer nut 620 abuts against the second gasket 610, driving the second gasket 610 to abut against the first connecting member 300. The second gasket 610 protects the component and prevents loosening. The second gasket 610 is sleeved on the second adjusting screw 600 and is located between the second double-layer nut 620 and the first connecting member 300. It is used to disperse the pressure of the nut and prevent the surface of the first connecting member 300 from being damaged due to concentrated force. The second double-layer nut 620 is connected to the second adjusting screw 600 by a thread. After tightening, it drives the second gasket 610 to press against the first connecting member 300, and uses friction to lock the position of the mounting member 200 to prevent it from loosening along the second direction.
[0063] With this arrangement, the mounting member 200, through its sliding connection with the tubular body of the mounting member 200 via the first connection hole 110 of the base 100, can slide directly in the second direction for primary adjustment. The mounting member 200, through its connection with the second connecting member 500 via the second adjustment screw 600, can slide again in the second direction for secondary adjustment. Primary adjustment allows for rapid, coarse adjustment of the target light's position; secondary adjustment allows for precise, fine-tuning, achieving millimeter-level precision control through threaded drive to ensure the target light is aligned with the measurement point.
[0064] See Figure 6 In some embodiments, the first connecting member 300 and / or the second connecting member 500 are configured with an adjustable steel, and a rubber cap 700 is provided at the end of the adjustable steel to prevent rainwater from flowing into the interior through the gap between the screw and the slide groove, avoid rusting of the components, and extend the service life of the bracket in outdoor environments.
[0065] In some embodiments, two first connecting members 300 are vertically provided, and two second connecting members 500 are vertically provided. Two second adjusting screws 600 arranged vertically are horizontally connected between each first connecting member 300 and each second connecting member 500. There are four second adjusting screws 600 in the embodiment of the present application. The two first connecting members 300 and the two second connecting members 500 are connected by four second adjusting screws 600 to form a rigid quadrilateral frame, which significantly improves the overall torsion and anti-overturning capabilities of the bracket and reduces shaking during the measurement process. The first adjustment component locks the position of the mounting member 200 along the first direction; the second adjustment component locks the position of the mounting member 200 along the second direction. The combination of the two realizes double fixation in a two-dimensional plane, ensuring the stability of the bracket in three-dimensional space.
[0066] Through the above arrangement, the first connecting member 300 and the second connecting member 500 can be installed as a connection base at any desired site. The three-degree-of-freedom adjustable fixing bracket of the embodiment of the present application avoids on-site implementation, saves time, is easy to operate, and has reliable connection, achieving the purpose of rapid deployment and rapid detection.
[0067] See Figure 1 At least one embodiment of the present application provides a photoelectric deflectometer target light, comprising a three-degree-of-freedom adjustable fixing bracket and a target light according to any of the above embodiments, wherein the target light is connected to a base 100 and rotates around a first direction.
[0068] According to the target light of the photoelectric deflectometer in the embodiment of the present application, the position and angle of the target light can be adjusted in three degrees of freedom according to the needs of different measurement angles and distances, which can ensure that the target light remains stable during the measurement process and is not affected by external interference. The position of the target light can also be finely adjusted to improve measurement accuracy and is easy to operate.
[0069] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application.
