[0002] Network video surveillance is an intelligent monitoring system based on IP network transmission. It digitizes the video signals captured by cameras and transmits them to storage devices and management platforms via a network (wired / wireless), enabling functions such as remote real-time viewing, video recording and storage, intelligent analysis, and alarm linkage.

[0003] Chinese patent CN215721929U discloses a network video surveillance terminal. This utility model uses a starting motor to provide driving force, which drives the rotation of the rotating shaft and turntable, thereby driving the rotation of the fixed base and camera, facilitating all-around shooting.

[0004] However, the device still has shortcomings: because the height of the support column is fixed, and the installation height of the monitor is often large, especially for ultra-high-definition monitoring, the installation height can reach more than 6 meters. At this height, the installation and subsequent maintenance of the monitor are very troublesome. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a network video surveillance terminal.

[0006] The technical solution of this utility model is as follows: A network video surveillance terminal includes a base, a vertical pipe on the base, a support seat communicating with the interior of the vertical pipe at the top of the vertical pipe, a rotating seat on the support seat, a horizontal pipe on the rotating seat, a vertical pipe on the horizontal pipe, a passageway inside the rotating seat, the horizontal pipe and the vertical pipe, a plurality of pulleys A spaced apart in the passageway, a fixed stake in the passageway, and a side groove on the inner wall of the vertical pipe, a movable plate with an inclined bottom rotatably installed in the side groove, and a male plug on the movable plate;

[0009] And a drive mechanism, which is mounted on the riser and drives the take-up roller to rotate.

[0010] Preferably, a diagonal brace is installed on the horizontal tube, and the diagonal brace is rotatably connected to the vertical tube on the same axis.

[0011] Preferably, a guide cover is provided at the bottom of the vertical tube, which is connected to the inside of the tube, and the inner diameter of the guide cover opening gradually increases from top to bottom.

[0012] Preferably, the movable plate is in a horizontal position before the slide contacts the movable plate, and the movable plate can only be flipped upwards.

[0013] Preferably, a permanent magnet A is provided on the inner wall of the side groove, and a permanent magnet B corresponding to permanent magnet A is provided on the movable plate. After the movable plate is flipped upward, the magnetic poles of the adjacent ends of permanent magnet A and permanent magnet B are the same.

[0014] Preferably, the number of pulleys B is at least two, so as to lengthen the distance between the steel wire ropes on both sides on the slide block by means of the two pulleys B.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] By configuring a cooperative structure consisting of guide wheels, fixed posts, take-up rollers, wire ropes, and a drive mechanism, the slide block can be easily pulled up or lowered. The drive mechanism uses a worm gear structure, preventing the take-up roller from rotating due to the weight of the slide block, thus ensuring stable lifting. A side groove is installed inside the vertical tube, with a movable plate inside. A male connector is placed on the movable plate, and a groove is created on the slide block, with a slider inside the groove. This allows the movable plate to automatically flip upwards under force and enter the groove at the appropriate position. When the slide block lands on the movable plate, the male connector is precisely inserted into the socket, ensuring circuit continuity. This structure also avoids the wire rope bearing the entire load alone, extending its service life. A drive component B is used to drive the rotating seat, enabling the monitor to operate 360 ​​degrees without blind spots or obstructions. Attached Figure Description

Detailed Implementation

[0025] Example 1

[0026] like Figures 1-5As shown, the present invention proposes a network video surveillance terminal, comprising a base 1, a slide 12, a take-up roller 17, and a drive mechanism. A vertical tube 2 is mounted on the base 1, and a support seat 3 communicating with the interior of the vertical tube 2 is mounted at its top. A rotating seat 4 is mounted on the support seat 3, a horizontal tube 5 is mounted on the rotating seat 4, and a vertical tube 7 is mounted on the horizontal tube 5. A passageway is formed within the rotating seat 4, the horizontal tube 5, and the vertical tube 7. Several pulleys A8 are spaced apart within the passageway, and fixed posts 51 are installed within the passageway. A side groove 72 is provided on the inner wall of the vertical tube 7, and a movable plate 10 with an inclined surface 1001 at its bottom is rotatably mounted within the side groove 72. A male connector 11 is mounted on the movable plate 10. A diagonal brace 6 is mounted on the horizontal tube 5, and the diagonal brace 6 is coaxially and rotatably connected to the vertical tube 2. A guide cover 71 communicating with the interior of the vertical tube 7 is provided at its bottom, and the inner diameter of the guide cover 71 gradually increases from top to bottom. The top of the slide block 12 is inserted into the vertical tube 7 and slidably connected to its inner wall. A limiting plate 13 is provided at the bottom of the slide block 12, and a monitor 14 is connected to the bottom of the limiting plate 13. A groove 121 is provided on the slide block 12, and the upper wall of the groove 121 contacts the upper end face of the movable plate 10. The slide block 12 is provided with a socket adapted to the male plug 11. A slider 15 is slidably arranged below the movable plate 10 in the groove 121. The slider 15 has an isosceles trapezoidal structure that is wider at the top and narrower at the bottom, and the wide side of the slider 15 is flush with the edge of the slide block 12. A pulley B16 is provided on the slide block 12. Before the slide block 12 contacts the movable plate 10, the movable plate 10 is in a horizontal state, and the movable plate 10 can only be rotated upwards. A permanent magnet A9 is installed on the inner wall of the side groove 72, and a permanent magnet B1002 corresponding to the permanent magnet A9 is installed on the movable plate 10. After the movable plate 10 is flipped upward, the magnetic poles of the permanent magnets A9 and B1002 are the same at their closest ends. A take-up roller 17 is rotatably installed inside the riser 2. A steel wire rope 18 is wound on the take-up roller 17. The steel wire rope 18 passes through each pulley A8 and pulley B16 in sequence and is connected to the fixed post 51. There are at least two pulleys B16 to lengthen the distance between the steel wire ropes 18 on both sides on the slide block 12. A drive mechanism is installed on the riser 2 and drives the take-up roller 17 to rotate. The drive mechanism includes a maintenance box 19 and a drive assembly A. The drive assembly A includes a worm gear 20 and a worm 21. The maintenance box 19 is connected to the riser 2. A maintenance door 191 is provided on the maintenance box 19. The roller shaft 171 of the take-up roller 17 extends into the maintenance box 19 and is rotatably connected to it. The worm gear 20 is coaxially connected to the roller shaft 171. The worm 21 is located inside the maintenance box 19 and is rotatably connected to the maintenance box 19. A hexagonal countersunk hole is provided at the end of the worm 21.

[0027] In this embodiment, when the monitor 14 needs to be inspected, the lock on the inspection door 191 is unlocked, and then the inspection door 191 is opened. A hex wrench is inserted into the hexagonal countersunk hole, and the worm gear 21 is rotated. The rotation of the worm gear 21 drives the worm wheel 20, the roller shaft 171, and the take-up roller 17 to rotate. The take-up roller 17 appropriately winds up the wire rope 18, using the wire rope 18 to pull the slide block 12 up to a certain height, causing the slider 15 to contact the inclined surface 1001 and push the movable plate 10 to first flip upwards and retract into the side groove 72. The slide block 12 is limited by the limiting plate 13 when it moves upward, so that the slider 15 cannot move above the movable plate 10. Then the worm gear 21 is reversed and the wire rope 18 begins to lower the slide block 12. At this time, due to the tension of the permanent magnet B1002, the slider 15 is pressed against it until the upper wall of the groove 121 contacts the upper end surface of the slider 15. Then the slide block 12 slides out of the vertical tube 7 under the action of gravity. When the slide block 12 is separated from the side groove 72, the movable plate 10 automatically returns to the horizontal state under the tension of the two permanent magnets. After the monitor 14 is inspected or maintained, reverse the worm gear 21 and use the wire rope 18 to pull the slide into the vertical tube 7. At this time, slow down the rotation speed. The top of the slide 12 first contacts the inclined surface 1001 and causes the movable plate 10 to flip up. Then, after the groove 121 and the side groove 72 are aligned, the movable plate 10 rotates back to the horizontal state. At this time, lower the slide 12 so that the male plug 11 is inserted into the socket, completing the circuit connection of the monitor 14. This operation can be tested by repeatedly pulling up and lowering the slide 12. When the slide 12 cannot descend after releasing the wire rope 18, it can be determined that the slide 12 falls on the movable plate 10.

[0028] Example 2

[0029] like Figure 1 and Figure 2 As shown, the network video surveillance terminal proposed in this utility model, compared with the first embodiment, has a rotating base 4 and a support base 3 rotatably connected coaxially. The rotating base 4 is provided with a driving component B that drives itself to rotate around the axis of the support base 3. The driving component B includes an internal gear ring 301, a motor 22 and a gear 23. The internal gear ring 301 is coaxially connected to the support base 3. A rotating shaft is rotatably provided on the rotating base 4. The gear 23 is coaxially connected to the rotating shaft and meshes with the internal gear ring 301. The body of the motor 22 is connected to the rotating base 4, and the output end of the motor 22 is connected to the rotating shaft.

[0030] In this embodiment, the motor 22 drives the rotating shaft and gear 23 to rotate. The gear 23 moves around the inner ring of the internal gear ring 301, thereby causing the rotating seat 4 to rotate, which in turn allows the monitor 14 to work 360 degrees without blind spots or obstructions.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
