Near the chassis of the management device, multiple cameras are arranged to conduct video monitoring on the surrounding area.

[0011] Furthermore, the support mechanism includes a fixed block, a cross bar, a sphere, a first fixing nut, and a first screw hole; two fixed blocks are fixedly connected to the side wall of the clamping assembly, one end of a cross bar is fixedly connected to the side wall of the fixed block, the other end of the cross bar is fixedly connected to a sphere, a first screw hole is opened through the upper end of the sphere, and the inner wall of the first screw hole is threadedly connected to the side wall of the first threaded post.

[0012] Furthermore, a first fixing nut is fixedly connected to the lower end of the sphere, the inner wall of the first fixing nut is flush with the inner wall of the first screw hole, and the inner wall of the first fixing nut is threadedly connected to the side wall of the first threaded post.

[0016] Furthermore, two fixing rings are fixedly connected to one side of the control box, and the inner wall of the fixing ring is in contact with the side wall of the second threaded post.

[0017] The beneficial effects of the present utility model:

[0018] 1. The control box is positioned with the pole through the first through hole at the upper end, and is connected to the wall layer of the pole with at least two first bolts through the threads to form a multi-point fixation. The U-shaped clamp of the clamping assembly clamps the pole through the second bolt and the locking nut, and is screwed into the wall layer of the pole through the third bolt thread to achieve a rigid connection between the clamp and the pole. At the same time, the second threaded column on one side of the control box extends into the inside of the control box, and the screw thread of the locking mechanism is screwed into the side wall groove of the second threaded column to further lock the control box and the pole, which can improve the resistance to lateral displacement caused by vibration and wind force, and solve the problem of easy loosening of the traditional clamp structure;

[0019] 2. The fixing block of the support mechanism is connected to the sphere through a crossbar, and the first fixing nut at the lower end of the sphere and the first screw hole at the upper end are threadedly connected to the first threaded column to form a double upper and lower limit. At the same time, the thread on the lower end side wall of one of the first threaded columns penetrates the two mounting tubes, and the mounting tubes are threadedly locked by an external threaded ring and an internal threaded ring, and the mounting tubes are fixed by a fifth bolt and a second fixing nut. This structure allows the gravity of the camera to be transmitted to the mounting tube through the first threaded column, and then dispersed to the vertical pole through the second threaded column, forming a rigid support chain of "camera-first threaded column-mounting tube-second threaded column-vertical pole". Compared with the traditional device that only relies on clamp support, the stability of the camera after installation is significantly improved;

[0020] 3. The internal thread ring is threadedly sleeved with two external thread rings at the same time, rigidly connecting the left and right mounting tubes as a whole. The fixing ring radially positions the second thread column, and cooperates with the screw of the locking mechanism to axially lock the second thread column to prevent the second thread column from rotating or displacing under strong winds. In addition, the square plate part of the clamp is evenly stressed by the symmetrically distributed second bolts and locking nuts, and the third bolt penetrates into the wall layer of the vertical pole to form an embedded fixation, reducing the relative sliding between the clamp and the vertical pole. The multiple support and locking structures synergistically enhance the wind resistance, so that the device can still remain stable in a strong wind environment, solving the problem of weak wind resistance of traditional devices;

[0021] 4. The second screw hole on the side wall of the sphere is tightened against the first threaded column through the fourth bolt, which can improve the fixation of the first threaded column. After the fourth bolt is screwed into the second screw hole, it is necessary to apply colloid at the joint to prevent the fourth bolt from being blown out of the second screw hole due to excessive wind force, thereby further improving the fixation effect of the camera. The threaded connection design between the mounting tube and the second fixing nut and the internal threaded ring can be quickly assembled by rotation, avoiding complicated alignment operations and improving construction efficiency.

[0035] An internal thread ring 23 is threadedly installed on the side walls of the two external thread rings 22 together;

[0036] A locking mechanism for locking the second threaded column 18 is provided on the inner wall of the control box 2.

[0037] During use, the control box 2 is sleeved on the side wall of the vertical rod 1, and then the control box 2 is fixed on the vertical rod 1 by using the first bolt 4.

[0038] Please refer to Figure 1 and Figure 4, in this embodiment, the clamping assembly includes a clamp 5, a second bolt 6, a lock nut 7, and a third bolt 8; a clamp 5 is circumferentially provided on the side wall of the vertical rod 1. The clamp 5 is U-shaped and both ends extend outward to form square plate parts. At least two second bolts 6 are threadedly installed through the two corresponding square plate parts. A lock nut 7 is threadedly installed on the side wall of the second bolt 6. By tightening the two corresponding lock nuts 7, the clamp 5 is locked on the side wall of the vertical rod 1.

The U-shaped structure of the clamp 5 and the square plate part cooperate with the second bolt 6 and the lock nut 7, and the clamp 5 and the vertical rod 1 can be initially fixed through mechanical clamping force. Then, the third bolt 8 is threadedly embedded into the wall layer of the vertical rod 1 to form a rigid connection. The double fixing method significantly improves the connection strength between the clamping assembly and the vertical rod 1, and effectively prevents the clamp 5 from circumferentially sliding due to vibration or wind force.

[0039] Please refer to Figure 1 and Figure 5 , in this embodiment, the support mechanism includes a fixed block 9, a cross bar 10, a sphere 11, a first fixing nut 12, and a first screw hole 13; two fixed blocks 9 are fixedly connected to the side wall of the clamping assembly. One end of a cross bar 10 is fixedly connected to the side wall of the fixed block 9. The other end of the cross bar 10 is fixedly connected to a sphere 11. A first screw hole 13 is opened through the upper end of the sphere 11. The inner wall of the first screw hole 13 is threadedly connected to the side wall of the first threaded column 16. The fixed block 9 forms a cantilever support structure with the sphere 11 through the cross bar 10, expanding the installation position of the camera 17 to the outside of the vertical rod 1 to avoid interference with the control box 2.

[0040] Please refer to Figure 1 and Figure 5 , in this embodiment, a first fixing nut 12 is fixedly connected to the lower end of the sphere 11. The inner wall of the first fixing nut 12 is flush with the inner wall of the first screw hole 13. The inner wall of the first fixing nut 12 is threadedly connected to the side wall of the first threaded column 16. The first fixing nut 12 and the first screw hole 13 are vertically aligned to form double-threaded limit for the first threaded column 16. Compared with a single screw hole connection, the threaded engagement length is significantly increased, and the axial connection strength between the first threaded column 16 and the sphere 11 is improved.

[0041] Please refer to Figure 1 and Figure 5, in this embodiment, a second screw hole 14 is formed in the side wall of the sphere 11, and a fourth bolt 15 is threadedly installed on the inner wall of the second screw hole 14. The second screw hole 14 communicates with the first screw hole 13. The fourth bolt 15 passes through the second screw hole 14 and abuts against the side wall of the first threaded post 16. The fourth bolt 15 tightly presses against the side wall of the first threaded post 16 through the second screw hole 14, adding a radial locking force on the basis of the threaded connection to form a double fixation structure of "threaded connection + frictional locking". It should be noted that after the fourth bolt 15 is screwed into the second screw hole 14, a colloid needs to be applied at the joint between the fourth bolt 15 and the second screw hole 14 to bond the fourth bolt 15 to the inner wall of the second screw hole 14 to prevent the fourth bolt 15 from being blown out of the second screw hole 14 by excessive wind force.

[0042] Please refer to Figure 1 and Figure 8 , in this embodiment, two vertical blocks 27 are fixedly connected to one end of the inner wall of the control box 2 close to the vertical rod 1. A plurality of mounting plates 28 are fixedly connected to the side walls of the two vertical blocks 27. The plurality of mounting plates 28 are equidistantly distributed in the vertical direction. By providing the plurality of mounting plates 28, it is convenient to install electronic devices on the mounting plates 28.

[0043] Please refer to Figure 1 and Figure 6 , in this embodiment, two fixing rings 20 are fixedly connected to one side of the control box 2. The inner wall of the fixing ring 20 fits with the side wall of the second threaded post 18. The inner wall of the fixing ring 20 fits with the second threaded post 18 to provide radial positioning support for the second threaded post 18 to prevent it from tilting or being eccentric during the installation process.

[0044] Embodiment 2: Please refer to Figure 8 , on the basis of Embodiment 1, the present application provides a technical solution: The locking mechanism includes a fixing plate 25 and a screw rod 26. Two fixing plates 25 are fixedly connected to the inner wall of the control box 2. The screw rod 26 is threadedly installed through the fixing plate 25. A screw groove is formed in the side wall of the other end of the second threaded post 18, and the screw rod 26 is threadedly installed in the inner wall of the screw groove. The fixing plate 25 forms a threaded connection with the screw groove of the second threaded post 18 through the screw rod 26 to axially lock the second threaded post 18 on the inner wall of the control box 2 to prevent it from rotating or axially displacing due to external forces. The threaded installation of the locking mechanism and the second threaded post 18 forms a two-way fixation. With the radial positioning of the fixing ring 20, a three-dimensional constraint on the second threaded post 18 is constituted, significantly enhancing the connection stiffness between the control box 2 and the vertical rod 1 and improving the overall wind and earthquake resistance of the device.

[0045] Working principle: During use, first, the control box 2 is sleeved on the side wall of the vertical rod 1 through the first through hole 3 at its upper end, so that the inner wall of the first through hole 3 fits with the side wall of the vertical rod 1. Then, at least two first bolts 4 are used to pass through the control box 2 and be threadedly installed in the wall layer of the vertical rod 1 to fix the control box 2 on the vertical rod 1;

[0046] Then, the two second threaded columns 18 are respectively threadedly installed on the inner walls of the threaded holes on one side of the control box 2, so that the second fixing nuts 19 fixedly connected to one end of the second threaded columns 18 are located outside the control box 2, and the other ends extend into the control box 2. Subsequently, the locking mechanism on the inner wall of the control box 2 is used, that is, the screw 26 threadedly installed through the fixing plate 25 is threadedly installed in the screw groove on the side wall of the other end of the second threaded column 18 to axially lock the second threaded column 18 on the inner wall of the control box 2;

[0047] After that, the two mounting cylinders 21 are manually threadedly installed on the inner walls of the two second fixing nuts 19 respectively. The mounting cylinders 21 and the second fixing nuts 19 are fixed by multiple fifth bolts 24 passing through the second fixing nuts 19 and threadedly installed in the wall layers of the mounting cylinders 21. Then, the internal thread ring 23 is simultaneously threadedly installed on the external thread rings 22 on the side walls of the two mounting cylinders 21, so that the two external thread rings 22 are rigidly connected into a whole through the internal thread ring 23;

[0048] Then, the clamping assembly is installed on the side wall of the vertical rod 1. Specifically, the U-shaped clamp 5 is wound around the vertical rod 1, and the second bolts 6 and locking nuts 7 on the two corresponding square plate parts are tightened to make the clamp 5 tightly hold the vertical rod 1. Then, the third bolts 8 on the side wall of the clamp 5 pass through the clamp 5 and are threadedly installed in the wall layer of the vertical rod 1 to realize the double fixation of the clamping assembly and the vertical rod 1;

[0049] Subsequently, on the fixed block 9 of the clamping assembly, the first threaded column 16 is installed through the sphere 11 connected by the cross bar 10. The lower end side wall of the first threaded column 16 is threadedly installed on the inner walls of the first screw hole 13 and the first fixing nut 12. Then, the fourth bolt 15 passes through the inner wall of the second screw hole 14 and abuts against the side wall of the first threaded column 16 to increase the radial locking force on the basis of the threaded connection;

[0050] Next, the first threaded column 16 on the support mechanism is rotated downward, so that the lower end side wall of one of the first threaded columns 16 is simultaneously threadedly installed on the inner walls of the two mounting cylinders 21, and the two mounting cylinders 21 form a support for the first threaded column 16;

[0051] At this time, the gravity of the camera 17 is transmitted to the mounting cylinder 21 through the first threaded column 16, and then dispersed to the vertical rod 1 through the second threaded column 18. At the same time, the inner wall of the fixing ring 20 on one side of the control box 2 is attached to the side wall of the second threaded column 18 to provide radial positioning support for the second threaded column 18 to prevent it from tilting or being eccentric. Combined with the axial locking of the locking mechanism, a three-dimensional constraint on the second threaded column 18 is formed, and finally the stable installation of the control box 2, the clamping assembly and the camera 17 is realized;

[0052] Finally, apply a colloid at the joint between the fourth bolt 15 and the second screw hole 14 to bond the fourth bolt 15 to the inner wall of the second screw hole 14, preventing the fourth bolt 15 from being blown out by excessive wind force and completing the locking after the angle adjustment of the camera 17.
