A base 103 is rotatably mounted on one end of the intermediate frame 102 away from the upper base frame 101, and an angle adjustment component is provided between the base 103 and the intermediate frame 102. The rotation axis of the upper base frame 101 and the rotation axis of the base 103 are perpendicular to each other in space. When the device is in use, the bottom of the base 103 contacts the lane monitoring pole.

[0029] like Figures 1 to 4 As shown, a secondary hoop bar 105 is rotatably installed on one side of the bottom of the base 103, and a main hoop bar 104 is rotatably installed on the other side of the bottom of the base 103. The secondary hoop bar 105 and the main hoop bar 104 are both made of stainless steel. An extension component is provided on the main hoop bar 104, and a fixing component is provided on the outer wall of the secondary hoop bar 105. When in use, the main hoop bar 104 and the secondary hoop bar 105 cooperate with the extension component to tighten the lane monitoring pole, thereby achieving the purpose of fixing the device on the lane monitoring pole. At the same time, the fixing component of the secondary hoop bar 105 also allows the device to be quickly disassembled and assembled.

[0030] like Figures 1 to 7 As shown, the angle adjustment component is arranged between the intermediate frame 102 and the upper base frame 101, and the base 103 and the intermediate frame 102. This embodiment mainly introduces the position and connection relationship of the angle adjustment component between the intermediate frame 102 and the base 103, and the position relationship of the angle adjustment component between the upper base frame 101 and the intermediate frame 102 corresponds one to one.

The center column 204 is fixedly connected to one side of the intermediate frame 102, and the center column 204 is slidably connected to the adjustment twist cover 201. A small spring 203 is provided between the adjustment twist cover 201 and the intermediate frame 102. The small spring 203 is used to limit the position of the adjustment twist cover 201. The two ends of the small spring 203 are fixedly connected to the adjustment twist cover 201 and the intermediate frame 102 respectively. 2 sliding connection, the outer side of the adjusting cover 201 is fixedly installed with a pointer 202 to indicate the current angle between the middle frame 102 and the base 103, and the outer side of the adjusting cover 201 is fixedly installed with a plurality of limit blocks 205 to limit the current position of the adjusting cover 201. The limit blocks 205 limit the position of the adjusting cover 201 and also limit the angular position of the middle frame 102 relative to the base 103. An angle scale 301 is provided on one side of the base 103. The angle scale 301 is used to cooperate with the pointer 202 to display the current The angle between the frame 102 and the base 103 is used to facilitate the adjustment of the camera angle during installation. The base 103 is provided with a plurality of limit grooves 302 on one side of the angle scale 301. The limit grooves 302 are arranged in an arc array on the base 103. The limit grooves 302 can fit with the limit blocks 205. When the limit grooves 302 fit with the limit blocks 205, the middle frame 102 can no longer rotate on the base 103. During specific use, the installer can pull the adjustment cover 201 to adjust the limit blocks 205 on the adjustment cover 201. 05 is out of contact with the limiting groove 302, so that the intermediate frame 102 can be rotated to adjust the angle between the intermediate frame 102 and the base 103. When adjusting the angle between the intermediate frame 102 and the base 103, the angle value indicated by the angle scale 301 and the pointer 202 can also be used for adjustment. After the angle is adjusted to the appropriate level, the user releases the restriction of the adjusting twist cover 201 and allows the limiting block 205 to fit into the limiting groove 302 again. When the angle adjustment component is used between the intermediate frame 102 and the upper base frame 101, the operation method is the same.

[0032] like Figure 3 、 Figure 8 、 Figure 9As shown, the extension component includes an engagement bar 401 and a small handle 402. The engagement bar 401 is fixedly connected to the small handle 402. Arc-shaped grooves are provided on both sides of the main hoop bar 104. The engagement bar 401 is slidably installed in the main hoop bar 104. One end of the engagement bar 401 is provided in the arc-shaped groove. The arc-shaped groove is used to limit the sliding trajectory of the engagement bar 401. The small handle 402 is provided on the outside of the main hoop bar 104. The small handle 402 is mainly used to assist the user in installation. During installation, the engagement bar 401 will be embedded in the secondary hoop bar 105. At this time, the engagement bar 401 can be connected to the secondary hoop bar 105. A plurality of oblique convex angles are provided on the outer wall of the engagement bar 401. The engagement bar 401 and the oblique convex angles are the main tightening parts of this device. The oblique convex angle on the engagement bar 401 is generally set to an obtuse angle, the purpose of which is to facilitate the disassembly and installation of this device.

[0033] like Figures 8 to 12 As shown, the fixing assembly includes a positioning shell 501, a positioning cam 502, a tooth block 504, and a rotating key 510. The positioning shell 501 is fixedly connected to the outer wall of the auxiliary hoop strip 105. The tooth block 504 is arranged in the auxiliary hoop strip 105. A plurality of oblique grooves are provided on the tooth block 504. The oblique grooves can fit with the oblique convex angles on the engaging strip 401. When the oblique grooves and the oblique convex angles fit together, the device is in a tightening state. A telescopic spring 503 is fixedly installed on the tooth block 504. The other end of the telescopic spring 503 is fixedly installed in the positioning shell 501. The positioning cam 502 is rotatably installed in the positioning shell 501. The rotation direction of the positioning cam 502 in the positioning shell 501 can only be Figure 9 When the positioning cam 502 rotates counterclockwise in the middle, a movable space for the positioning cam 502 to rotate counterclockwise by ninety degrees is provided in the positioning housing 501 .

[0034] like Figures 8 to 12 As shown, a limiting column 508 is provided on one side of the positioning cam 502, and a straight groove is provided on the limiting column 508. A sliding snap ring 506 is slidably installed on the outer wall of the limiting column 508. The sliding snap ring 506 is slidably connected to the inner wall of the positioning shell 501, and the sliding snap ring 506 slides along the axial direction of the positioning cam 502 in the positioning shell 501. A plurality of tension springs 505 are fixedly installed on the sliding snap ring 506, and the other end of the tension spring 505 is fixedly installed on the positioning shell 501. The tension spring 505 is used to restore the position of the sliding snap ring 506 after lateral movement. An outer protrusion 507 is fixedly installed at the position where the sliding snap ring 506 is provided on the inner wall of the positioning shell 501. The sliding snap ring 506 is slidably connected to the outer protrusion 507. Figure 11In the state shown in the figure, the sliding snap ring 506 at this time limits the movement of the positioning cam 502 and the limit column 508. Only after the sliding snap ring 506 is pushed a certain distance in the positioning shell 501 and disengages from the outer protrusion 507 and the limit column 508, can the sliding snap ring 506 release the restriction on the positioning cam 502. An entrance plate 509 is fixedly installed on one side of the positioning shell 501. The function of the entrance plate 509 is to close one side of the limit column 508 to prevent the limit column 508 from being outside the positioning shell 501. At the same time, the entrance plate 509 is also provided to prevent the structure of the limit column 508 in the positioning shell 501 from being directly seen.

[0035] like Figures 10 to 13 As shown, the rotary key 510 is the control key of the device, which is used to facilitate the user to install and disassemble the device, and at the same time prevent the device from being disassembled by non-staff. The rotary key 510 is provided with a side extrusion block 512, and one end of the rotary key 510 with the side extrusion block 512 is also fixedly installed with a transverse protrusion 511. The inner diameter of the transverse protrusion 511 is larger than the outer diameter of the limit column 508. When in use, the side extrusion block 512 is used to embed into the straight groove of the limit column 508, and the limit column 508 is used to push the sliding clamping ring 506 to move in the positioning shell 501. Thereafter, the user turns the key 510 to drive the positioning cam 502 to rotate, and the rotation of the positioning cam 502 can allow the positioning cam 502 in the fixing assembly to release or restore the restriction on the tooth block 504, and the restriction of the tooth block 504 determines whether the device will lock the engaging strip 401.

[0036] Working principle of this device: When installing this device, the installation order is to install the camera on this device first (do not connect the camera data cable and power cable), and then install this device on the lane monitoring pole. This device must be installed on a cylindrical lane monitoring pole. In normal state, this device is Figure 1 and Figure 2 In the state shown in , during installation, the user turns the key 510 ninety degrees to release the restriction on the tooth block 504. At this time, the small handle 402 is pulled to retract the engaging strip 401 into the main hoop strip 104 and overlap with the main hoop strip 104. In this way, a gap is formed between the secondary hoop strip 105 and the main hoop strip 104, and the device can be placed on the lane monitoring pole through this gap. The lane monitoring pole needs to be installed between the main hoop strip 104 and the secondary hoop strip 105. During installation, it is necessary to make the rubber pressure block 303 contact with the lane monitoring pole. During installation, it is necessary to ensure that the device is as vertical as possible to the ground.

[0037] After the device is placed on the lane monitoring pole, the engaging strip 401 can be pulled to insert the engaging strip 401 into the secondary hoop strip 105. When the engaging strip 401 continues to penetrate into the secondary hoop strip 105, the engaging strip 401 will bring the main hoop strip 104 and the secondary hoop strip 105 closer. If the diameter of the lane monitoring pole is large at this time, the engaging strip 401 may not penetrate too deep. However, if the diameter of the lane monitoring pole is small, the engaging strip 401 can penetrate as deep as possible into the secondary hoop strip 105, thereby improving the stability of the device on the lane monitoring pole. When the engaging strip 401 penetrates into the secondary hoop strip 105, the oblique groove on the tooth block 504 fits with the oblique convex angle on the engaging strip 401. When the user determines that the engaging strip 401 cannot move, the engaging strip 401 is engaged. The key 510 can be rotated ninety degrees, so that the key 510 brings the positioning cam 502 back to its original state, and the positioning cam 502 limits the movement of the tooth block 504, so that the tooth block 504 fits with the meshing bar 401, so that the position of the meshing bar 401 can be fixed. In the process of pulling and fixing the meshing bar 401, the secondary hoop bar 105 and the main hoop bar 104 can produce a certain degree of elastic deformation due to the change in the outer diameter of the lane monitoring pole, so that the main hoop bar 104 and the secondary hoop bar 105 can fit more firmly on the outer wall of the lane monitoring pole. After fixing the device, the corresponding area monitored by the camera can be adjusted by a spirit level or other equipment, and the specific adjustment method is achieved through the angle adjustment component.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
