Description

Technical Field

[0001] This utility model relates to the field of monitoring devices, and in particular to a campus security monitoring system that is easy to install and adjust. Background Technology

[0002] Currently, campus security systems generally adopt a combination of infrared beam detectors, electronic fences, and ordinary surveillance cameras. These monitoring systems are usually installed on specially designed poles, and multiple monitoring devices are installed on the same pole to monitor different angles in real time.

[0003] However, with current monitoring devices, the camera's shooting angle needs to be confirmed in advance during the fixing process with the mounting pole before installation. Furthermore, it cannot be easily adjusted after installation. Moreover, the camera is fixed to the mounting pole using welding or bolts, making it difficult to install and remove the camera and posing significant challenges for later maintenance. Therefore, this solution proposes a campus security monitoring system that is easy to install and adjust. Summary of the Invention

[0004] This utility model proposes a campus security monitoring system that is easy to install and adjust, solving the problem of inconvenient installation and adjustment of existing campus security monitoring systems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An easy-to-install and adjust campus security monitoring system includes a support column and a camera. The top of the support column is provided with a mounting part, and a fixing part for fixing the camera is installed on the mounting part. The bottom of the camera is provided with a fixing block for connecting with the fixing part. The mounting part includes multiple sets of adjustment mechanisms coaxially fixed from bottom to top. Each adjustment mechanism includes a fixing ring, a mounting cylinder rotatably connected to the top of the fixing ring, and a locking assembly installed on the outer periphery of the fixing ring for locking the mounting cylinder. The bottom of the fixing ring in the upper adjustment mechanism is rotatably connected to the mounting cylinder in the lower adjustment mechanism, and the fixing ring in the lowest adjustment mechanism is fixedly connected to the top of the support column. The fixing part includes a fixing seat installed on the outer periphery of the mounting cylinder and a limiting component installed on the front of the fixing seat. The front of the mounting cylinder has a mounting hole for engaging the fixing block. The limiting component includes a limiting plate rotatably connected to the front of the fixing seat via a connector and used to limit the fixing block within the mounting hole, and an adjusting component for driving the limiting plate to rotate.

[0006] Through the above technical solution, the installation part can be set up to facilitate the adjustment of the camera's orientation during installation and debugging, while the fixing part can facilitate the quick installation and removal of the camera by the installers, reducing the difficulty of later maintenance.

[0007] As a further improvement to the above solution, the locking assembly includes a limiting ring fixed to the top of the fixing ring and coaxially arranged therewith, and a locking bolt threaded to the outer circumference of the limiting ring. The limiting ring is sleeved on the outer circumference of the mounting cylinder, and one end of the locking bolt abuts against the outer circumference of the mounting cylinder.

[0008] The above technical solution utilizes the static friction between the locking bolt and the mounting cylinder to lock the mounting cylinder.

[0009] As a further improvement to the above scheme, 2-3 sets of connecting rods are fixed between the two fixed rings in two adjacent adjustment mechanisms to limit their rotation, and the connecting rods are located inside the mounting cylinder.

[0010] The above technical solution ensures that the fixed ring will not rotate.

[0011] As a further improvement to the above solution, the front of the fixed base is provided with a mounting groove for installing the limiting component. The mounting groove is coaxially arranged with the mounting hole. The adjusting component includes multiple sets of limiting plates installed in the mounting groove and a gear ring rotatably connected in the mounting groove for driving the multiple limiting plates to rotate. A rotating shaft rotatably connected to the mounting groove is fixed on one side of the limiting plate. A transmission gear that matches the inner ring of the gear ring is sleeved on the outer circumference of the rotating shaft. When the fixed block is engaged in the mounting hole, the limiting plate abuts against the outside of the fixed block to restrict the fixed block in the mounting hole.

[0012] The above technical solution allows for the convenient rotation of multiple limit plates by rotating the gear ring.

[0013] As a further improvement to the above solution, the limiting plate is threaded with fixing bolts for connecting the fixing block, and the fixing block is provided with multiple fixing holes for connecting the fixing bolts.

[0014] With the above technical solution, after one end of the fixing bolt is screwed into the fixing hole, the fixing block and the limiting plate can be fixed together, thereby preventing the fixing block from loosening.

[0015] As a further improvement to the above solution, the gear ring is threaded with a limiting bolt for restricting its rotation, and two limiting holes for connecting the limiting bolt are opened in the mounting groove.

[0016] With the above technical solution, the toothed ring can be locked after the limiting bolt is screwed into the limiting hole, preventing it from loosening.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The mounting section allows for adjustment of the camera's orientation by rotating the mounting cylinder, making it easy to adjust the monitoring angle according to monitoring needs and greatly facilitating installation and debugging by maintenance personnel.

[0018] 2. By setting the fixing part, the fixing block can be snapped into the fixing base and then the fixing block can be restricted in the mounting hole by the limiting component, so as to quickly fix the camera. Similarly, when disassembling, the camera can be easily removed from the fixing block by simply releasing the limiting component and the fixing block, thus achieving the purpose of convenient camera installation and removal.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0021] Please combine Figure 1 - Figure 7This embodiment of a campus security monitoring system that is easy to install and adjust includes a support column 1 and a camera 3. The top of the support column 1 is provided with a mounting part 2, and a fixing part 4 for fixing the camera 3 is installed on the mounting part 2. The bottom of the camera 3 is provided with a fixing block 5 for connecting with the fixing part 4. The support column 1 has a hollow structure, which facilitates the routing of cables inside.

[0022] The mounting section includes multiple sets of adjustment mechanisms coaxially fixed from bottom to top. Each adjustment mechanism includes a retaining ring 204, a mounting cylinder 201 rotatably connected to the top of the retaining ring 204, and a locking assembly installed on the outer periphery of the retaining ring 204 for locking the mounting cylinder 201. The bottom of the retaining ring 204 in the upper adjustment mechanism is rotatably connected to the mounting cylinder 201 in the lower adjustment mechanism. The retaining ring 204 in the lowest adjustment mechanism is fixedly connected to the top of the support column 1. Two to three sets of connecting rods 205 are fixed between the two retaining rings 204 in adjacent adjustment mechanisms to limit their rotation. Furthermore, the connecting rod 205 is located inside the mounting cylinder 201. The setting of the connecting rod 205 prevents the fixing ring 204 from rotating. When it is necessary to adjust the shooting angle of the camera 3 during installation, simply release the locking component from locking the mounting cylinder 201, and then rotate the mounting cylinder 201 to adjust the orientation of the fixing part 4. The camera 3 is fixed on the fixing part 4, which allows for convenient and quick adjustment of the shooting angle of the camera 3. After adjustment, the mounting cylinder 201 can be locked using the locking component. The setting of multiple adjustment mechanisms allows for the convenient installation of multiple sets of cameras on the support column 1.

[0023] In this embodiment, the locking assembly includes a limiting ring 202 fixed to the top of the fixing ring 204 and coaxially arranged therewith, and a locking bolt 203 threadedly connected to the outer periphery of the limiting ring 202. The limiting ring 202 is sleeved on the outer periphery of the mounting cylinder 201, and one end of the locking bolt 203 abuts against the outer periphery of the mounting cylinder 201. When the locking assembly releases the locking state of the mounting cylinder 201, the locking bolt 203 disengages from the outer periphery of the mounting cylinder 201, and the mounting cylinder 201 can rotate freely with the axis of the support column 1 as the rotation center. When the locking assembly is locked, one end of the locking bolt 203 abuts against the outer periphery of the mounting cylinder 201, thereby using the static friction between the locking bolt 203 and the outer periphery of the mounting cylinder 201 to lock the mounting cylinder 201, thereby achieving the purpose of conveniently locking the mounting cylinder 201. Example

[0024] Combination Figure 2 - Figure 7This embodiment, based on embodiment 1, further improves upon the following: the fixing part 4 includes a fixing seat 401 installed on the outer periphery of the mounting cylinder 201 and a limiting component installed on the front side of the fixing seat 401. The front side of the mounting cylinder 201 has a mounting hole 404 for engaging the fixing block 5. The limiting component includes a limiting plate 403 rotatably connected to the front side of the fixing seat 401 via a connector and used to restrict the fixing block 5 within the mounting hole 404, and an adjusting component for driving the limiting plate 403 to rotate. The front side of the fixing seat 401 has a mounting groove 408 for installing the limiting component, and the mounting groove 408 is coaxially arranged with the mounting hole 404. The adjusting component includes multiple sets of limiting plates 403 installed within the mounting groove 408 and a gear ring 402 rotatably connected within the mounting groove 408 for driving the multiple limiting plates 403 to rotate. A rotating shaft 410 rotatably connected to the mounting groove 408 is fixed to one side of the limiting plate 403. A transmission gear 405, which meshes with the inner ring of the gear ring 402, is fitted around the fixed block 5. When the fixed block 5 is engaged inside the mounting hole 404, the limiting plate 403 abuts against the outer side of the fixed block 5 to restrict the fixed block 5 within the mounting hole 404. The outer circumference of the fixed block 5 meshes with the mounting hole 404. When fixing the camera 3, the gear ring 402 is rotated first to drive multiple rotating shafts 410 to rotate, thereby causing multiple limiting plates 403 to rotate and deviate from the outside of the mounting hole 404. In this way, the limiting plates 404 will not block the fixed block 5 from being inserted into the mounting hole 404. After the fixed block 5 is inserted into the mounting hole 404, the gear ring 402 is reversed, thereby causing multiple limiting plates 403 to reverse back, so that the limiting plates 403 block the outer side of the fixed block 5, thereby restricting the fixed block 5 within the mounting hole 404 and preventing it from falling off. Finally, the gear ring 402 is locked to keep the limiting plates 403 from rotating, thus achieving the purpose of conveniently fixing and removing the camera 3.

[0025] Furthermore, the limiting plate 403 is threaded with a fixing bolt 406 for connecting the fixing block 5. The fixing block 5 has multiple fixing holes 6 for connecting the fixing bolt 406. After the limiting plate 403 blocks the outside of the fixing block 5 and the fixing bolt 406 is aligned with the fixing hole 6, the fixing bolt 406 is screwed into the fixing hole 6, thereby fixing the fixing block 5 and the limiting plate 403 together. This can effectively prevent the fixing block 5 from loosening, thereby further ensuring the stability of the camera 3.

[0026] In this embodiment, a limiting bolt 407 for limiting its rotation is threaded onto the gear ring 402. Two limiting holes 409 for connecting the limiting bolt 407 are provided in the mounting groove 408. The distance between the two limiting holes 409 is the length through which the limiting bolt 407 rotates when the gear ring 402 drives the transmission gear 405 to rotate 90 degrees. When the limiting bolt 407 is aligned with the limiting hole 409, the limiting bolt 407 can be screwed into the limiting hole 409, thereby locking the gear ring 402 and preventing the limiting plate 403 from rotating. When the limiting plate 403 is used to block the outside of the fixing block 5 to restrict it inside the mounting hole 404, the limiting bolt 407 can be screwed into one of the limiting holes 409 when it is aligned with it, thereby locking the gear ring and keeping the limiting plate 403 blocked outside the fixing block 5 and stationary, thereby restricting the fixing block 5 inside the mounting hole 404.

[0027] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
