Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to a network security monitoring device. Background Art

[0002] The monitoring system is one of the most widely used systems in the security system. The most suitable construction site monitoring system on the market is the handheld video communication device. Video monitoring is now the mainstream. From the earliest analog monitoring to the popular digital monitoring in the past few years to the emerging network video monitoring, earth-shaking changes have taken place. Today, when IP technology is gradually unifying the world, it is necessary to re-understand the development history of video monitoring systems.

[0003] At present, in the prior art, most monitoring devices are installed on metal columns through fixing rings, but the surface of general metal columns is relatively smooth, so when the fixing ring stays on the metal column for a long time, the fixing ring may slide down. In view of this, we propose a network security monitoring device. Utility Model Content

[0004] The main purpose of the utility model is to provide a network security monitoring device, which can solve the problems raised in the above technical background.

[0005] In order to achieve the above-mentioned object, the utility model proposes a network security monitoring device, comprising a device body, a surface of which is provided with a fixing device, and the fixing device comprises:

[0006] A fixing ring, the inner wall of which is hinged to the surface of the mounting ring, the inner wall of which is slidably connected with an intermediate plate, the upper surface of which is fixedly connected to one end of a connecting column, the other end of which is fixedly connected to the bottom surface of a pressing plate, and the surface of the connecting column is slidably connected to the inner wall of the fixing ring.

[0007] Preferably, a sliding column is fixedly connected to the bottom surface of the middle plate, a positioning block is fixedly connected to the surface of the sliding column, the surface of the sliding column is slidingly connected to the inner wall of the rotating sleeve, and the bottom surface of the rotating sleeve is rotatably connected to the inner wall of the fixed ring.

[0008] Preferably, a slide groove is provided on the inner wall of the rotating sleeve, a positioning block is slidably connected to the inner wall of the slide groove, the inner wall of the rotating sleeve is fixedly connected to one end of a spring, and the other end of the spring is fixedly connected to the bottom surface of the sliding column.

[0009] Preferably, a friction block is fixedly connected to the surface of the rotating sleeve, the inner wall of the friction block is hinged to one end of the linkage rod, and the other end of the linkage rod is hinged to the inner wall of the friction block.

[0010] Preferably, the inner wall of the friction block is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the inner wall of the friction block.

[0011] Preferably, the device body includes a cover plate, a camera is fixedly connected to the bottom surface of the cover plate, an adjuster is fixedly connected to the bottom surface of the camera, an inner wall of the adjuster is hinged to one end of a connecting rod, and the other end of the connecting rod is fixedly connected to the surface of the fixing device.

[0012] The utility model provides a network security monitoring device, which has the following beneficial effects:

[0013] (1) The network security monitoring device, through the friction block, fixes the fixing ring and the mounting ring on the mounting column by bolts. At this time, the pressing plate is pressed, so that the pressing plate pushes the middle plate downward through the connecting column, so that the middle plate pushes the sliding column downward, so that the positioning block on the sliding column drives the rotating sleeve to rotate through the sliding groove inside the rotating sleeve, so that the rotating sleeve drives the friction block to tilt up, and further fixes the surface of the mounting column. At this time, the spring is compressed by the sliding column, and the positioning block is stuck in the sliding groove to complete the fixation. When it is necessary to release the further fixation of the fixing device, the pressing plate is pressed again to make the sliding column move downward, so that the positioning block is separated from the sliding groove and is pushed upward by the spring, thereby driving the rotating sleeve to rotate through the sliding groove, and retracting the friction block to release the lock.

[0014] (2) The network security monitoring device has a linkage rod and a connecting rod. When the rotating sleeve rotates, the linkage rod and the connecting rod will synchronize all the surrounding rotating sleeves to rotate together, thereby avoiding a single rotating sleeve from getting stuck, thereby improving the stability of the fixing device.
