[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0021] The following discussion provides multiple embodiments of the present application. Although each embodiment represents a single combination of the application, different embodiments of the present application can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments described. Therefore, if one embodiment includes A, B, C, and another embodiment includes a combination of B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, D, even though the embodiment may not be clearly recorded in the following text.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0023] like Figure 1 and Figure 2 As shown, the adjustment device for adjusting the reflector provided in the present application includes: a base 10 , a column 20 , a center seat 30 , a fixing cover 40 , an adjustment screw 50 and an adjustment assembly 60 .

[0024] The base 10 has a receiving cavity.

[0025] The column 20 is supported on the base 10 , and one end of the column 20 is supported on the bottom wall of the accommodating cavity.

[0026] A guide hole 31 is provided on the central seat 30 , and the column 20 is located in the guide hole 31 . The central seat 30 can slide on the column 20 , and the central seat 30 is used to fix the reflector.

[0027] The fixing cover 40 is fixedly connected to the center seat 30. The fixing cover 40 and the center seat 30 are fixedly connected by threads. On the one hand, the threaded connection has high connection reliability, thereby ensuring the connection reliability between the fixing cover 40 and the center seat 30; on the other hand, the threaded connection is easy to disassemble, thereby facilitating the replacement and maintenance of the fixing cover 40 and the center seat 30.

[0028] The adjusting screw 50 passes through the fixing cover 40 and is pressed against the top of the column 20. The adjusting screw 50 is threadedly connected to the fixing cover 40. The adjusting screw 50 is used to adjust the position of the center seat 30 in the direction of the central axis of the column 20. The adjusting screw 50 and the fixing cover 40 are connected by threads. On the one hand, the threaded connection has high connection reliability, thereby ensuring the connection reliability between the adjusting screw 50 and the fixing cover 40. On the other hand, rotating the adjusting screw 50 can change the position of the fixing cover 40 on the adjusting screw 50, which is convenient to adjust and simple to operate, thereby ensuring the comfort of the product.

[0029] The adjustment assembly 60 is disposed on the base 10 and located between the base 10 and the column 20 , and is used to adjust the position of the center seat 30 on a plane perpendicular to the central axis of the column 20 .

[0030] By rotating the adjusting screw 50, the fixed cover 40 moves on the adjusting screw 50 under the action of the thread, thereby adjusting the position of the fixed cover 40 on the adjusting screw 50, and the fixed cover 40 drives the center seat 30 to move, so that the center seat 30 slides on the column 20, thereby adjusting the position of the center seat 30 in the direction of the central axis of the column 20. The adjusting screw 50 has a simple structure and is easy to adjust. The adjusting assembly 60 is adjusted to adjust the position of the center seat 30 on the plane perpendicular to the central axis of the column 20. The position of the reflector can be adjusted from multiple degrees of freedom through the adjustment device, thereby ensuring the assembly accuracy of multiple reflectors. Multiple reflectors are spliced ​​to form a reflective surface.

[0031] The adjustment device provided by the present application has a simple structure and is easy to assemble. The adjustment device can be quickly assembled into place, thereby enabling rapid adjustment of the reflector. In addition, the connection strength between the base 10, the column 20, the center seat 30, the fixing cover 40 and the adjusting screw 50 is high, thereby ensuring the overall strength of the adjustment device and ensuring the reliability of the adjustment device.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the adjustment device further includes: a top cover 80 , a pull plate 90 and a locking screw 100 .

[0033] The top cover 80 is pressed onto the fixed cover 40 .

[0034] One end of the pull plate 90 is connected to the top cover 80 , and a connecting hole 91 is provided on the other end of the pull plate 90 . The connecting hole 91 is a long strip-shaped hole.

[0035] The locking screw 100 passes through the connecting hole 91 and is connected to the base 10 . The locking screw 100 can be pressed on the pulling plate 90 .

[0036] After the center seat 30 is adjusted by adjusting the screw 50 and the adjusting assembly 60, adjust the position of the locking screw 100 in the connecting hole 91, and then screw the locking screw 100 into the base 10 and press the pull plate 90, so that the pull plate 90 is fixedly connected to the base 10. The pull plate 90 applies pressure to the fixed cover 40 through the top cover 80, and the center seat 30 and the base 10 are locked, thereby preventing the center seat 30 from shaking relative to the base 10, thereby ensuring the reliability of the product. Conversely, when it is necessary to adjust the position of the center seat 30, the locking screw 100 is screwed out of the base 10, so that the pull plate 90 can move relative to the base 10, the pressure acting on the fixed cover 40 through the top cover 80 disappears, and the adjusting screw 50 is rotated to adjust the position of the center seat 30 on the column 20.

[0037] The top cover 80, the pull plate 90 and the locking screw 100 are simple in structure and easy to operate, so that the center seat 30 and the base 10 can be quickly locked, which improves the comfort of use of the adjustment device and further increases the market competitiveness of the product.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the adjustment device further includes: a locking nut 110 .

[0039] The locking nut 110 is disposed on the adjusting screw 50 and pressed against the fixing cover 40 .

[0040] After the center seat 30 is adjusted by adjusting the screw 50 and the adjusting assembly 60, the locking nut 110 is tightened to prevent the adjusting screw 50 from rotating. The adjusting screw 50 is locked to prevent the adjusting screw 50 from rotating due to external force during use of the adjusting device, thereby preventing the center seat 30 from sliding on the column 20. This ensures the reliability of the use of the adjusting device and increases the market competitiveness of the product.

[0041] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the adjustment device further includes: a fixing frame 120 .

[0042] The base 10 is fixed on the fixing frame 120 .

[0043] The fixing frame 120 is fixed on the back frame for mounting the reflective surface. If the base 10 is fixed on the back frame, in order to ensure the connection strength between the base 10 and the back frame, multiple connection structures will inevitably be provided on the back frame, resulting in low strength of the base 10, which affects the service life of the product. As an auxiliary connection structure, the fixing frame 120 can be provided with multiple connection structures on the back frame without reducing the overall strength of the fixing frame 120, thereby being able to fully ensure the connection strength between the adjustment device and the back frame, thereby ensuring the reliability of the product.

[0044] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, a fixing hole is provided on the fixing frame 120, and the fixing screw 130 passes through the fixing hole to be connected to the base 10, and the fixing screw 130 can be pressed on the fixing frame 120, and the fixing hole is a long strip hole.

[0045] By adjusting the position of the fixing screw 130 in the fixing hole and the position of the base 10 on the fixing frame 120, the position of the center seat 30 is roughly adjusted, and then the position of the center seat 30 is finely adjusted by adjusting the screw 50 and the adjusting assembly 60, thereby ensuring the adjustment accuracy of the reflector.

[0046] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, a guide groove 32 is provided on the hole wall of the guide hole 31 , and a guide flat key 24 is provided on the column 20 . The guide flat key 24 is located in the guide groove 32 and can slide in the guide groove 32 .

[0047] The cooperation between the guide flat key 24 and the guide groove 32 plays a guiding role, avoiding the shaking of the center seat 30 during the sliding process, thereby ensuring that the center seat 30 slides steadily and smoothly on the column 20, thereby ensuring the comfort of the product.

[0048] The column 20 is provided with a keyway, and the guide flat key 24 is arranged in the keyway. In addition, the guide flat key 24 and the column 20 are made by an integral casting process, or the guide flat key 24 and the column 20 are two separate parts, and the two parts are assembled together when used. Those skilled in the art can select the specific form of the guide flat key 24 according to specific requirements and needs.

[0049] Several embodiments of the adjustment component are described in detail below:

[0050] Embodiment 1

[0051] like Figure 1 and Figure 2 As shown, the adjustment assembly 60 includes: a fixing plate 61 and a plurality of adjustment screws 62 .

[0052] The fixing plate 61 is fixed on the column 20 and is located in the accommodating cavity, with a gap between the fixing plate 61 and the cavity wall of the accommodating cavity. The fixing plate 61 is perpendicular to the column 20, and the side surface of the fixing plate 61 is the surface of the fixing plate 61 parallel to the axis of the column 20.

[0053] The adjusting top screw 62 is screwed on the base 10 and passes through the base 10 to press against the side surface of the fixing plate 61 . A plurality of adjusting top screws 62 are arranged along the circumference of the base 10 and can move relative to the base 10 .

[0054] Rotate the adjusting top screw 62 to change the length of the adjusting top screw 62 extending into the accommodating cavity, adjust the distance between the fixing plate 61 and the cavity wall of the accommodating cavity, and the adjusting top screw 62 pushes the fixing plate 61 to move. The fixing plate 61 drives the center seat 30 to move through the column 20, thereby adjusting the position of the center seat 30 on the plane perpendicular to the central axis of the column 20. The fixing plate 61 and multiple adjusting top screws 62 have a simple structure, convenient adjustment, and simple operation, thereby ensuring the comfort of the product.

[0055] In a specific embodiment of the present application, the fixing plate 61 is a rectangular plate, which includes four side surfaces, and the four side surfaces are all against the adjusting top screws 62. By adjusting the adjusting top screws 62 in four directions, the position of the center seat 30 can be adjusted from multiple degrees of freedom. Of course, there are many shapes of the fixing plate 61, such as circular, triangular, hexagonal, etc., which are not listed here one by one. Those skilled in the art can select the shape of the fixing plate 61 according to the specific adjustment accuracy.

[0056] In one embodiment of the present application, the adjustment device further includes: a support plate 70 .

[0057] The support plate 70 is fixed on the column 20 to support the fixing plate 61. The column 20 is provided with an annular groove, and the support plate 70 is inserted into the annular groove and connected to the column 20 by screws.

[0058] The provision of the support plate 70 ensures the connection area between the column 20 and the fixing plate 61, thereby ensuring the connection strength between the fixing plate 61 and the column 20, and further ensuring the reliability of the product.

[0059] In one embodiment of the present application, the column 20 includes a column body 21 and a ball head 22 .

[0060] The column 21 is located in the guide hole 31, the adjusting screw 50 is pressed against one end of the column 21, and the ball head 22 is arranged at the other end of the column 21 and can roll relative to the column 21 so that the column 21 deflects relative to the base 10, and the ball head 22 is pressed against the cavity wall of the accommodating cavity.

[0061] The arrangement of the ball head 22 enables the friction between the column 21 and the cavity wall to be rolling friction, so that the column 20 can slide smoothly in the base 10, ensuring the comfort of the product.

[0062] In one embodiment of the present application, at least some of the multiple adjusting top screws 62 have asymmetric contact points with different sides. During the adjustment of the top screws 62, the asymmetric adjusting top screws 62 can cause the fixing plate 61 to tilt, thereby driving the center seat to tilt through the column 20, increasing the adjustment range of the center seat and increasing the market competitiveness of the product. During the above adjustment process, due to the setting of the ball head 22, during the tilting of the column 20, the column 21 can smoothly tilt relative to the ball head 22, ensuring the comfort of the product.

[0063] In one embodiment of the present application, a step surface 23 is provided on the column 20 , and the step surface 23 presses against the fixing plate 61 .

[0064] The setting of the step surface 23 ensures the connection area between the column 20 and the fixing plate 61, thereby ensuring the connection strength between the fixing plate 61 and the column 20, and further ensuring the reliability of the product.
