Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a dustproof sealing device for PTZ cameras. Background Technology

[0002] The concept of PTZ cameras originated from people's demand for convenient monitoring equipment. In the last century, the market wanted cameras to be simpler and easier to use, so the concept of PTZ cameras gradually emerged. The first PTZ camera was launched in 2000, marking the beginning of the practical application stage of PTZ cameras. During this period, PTZ cameras were based on the integration of pan-tilt-zoom (PTZ) systems, communication systems, and camera systems as their core technologies. Their main features were large monitoring range, fast operation speed, optical zoom, and accurate positioning. They have gone through the development stages from standard definition to infrared high definition, and then to intelligent high definition. Now they are gradually entering the era of artificial intelligence. In the standard definition era, motorized zoom lens technology continued to develop; in the infrared high definition era, active infrared night vision technology has matured, providing technical support for PTZ cameras to monitor in low-light environments.

[0003] PTZ cameras are important video surveillance devices. They contain many delicate optical and electronic components. Dust entering the camera can adhere to the lens surface, reducing image clarity and contrast. Dust on the lens can also cause blurry, speckled images, affecting monitoring performance. Existing PTZ cameras are simply encased in a shell, leaving large gaps at joints and moving parts. Rubber sealing rings are used at the shell seams, which can partially fill these gaps and prevent dust from entering. However, as dust enters the pan / tilt unit from the shell joints during rotation, traditional sealing methods are insufficient to completely prevent dust from entering. After prolonged storage, dust can age and deform, reducing the sealing effectiveness. Furthermore, in harsh environments, such as windy outdoor environments or industrial sites with high dust concentrations, these traditional dustproof measures are ineffective in protecting the internal components of the PTZ camera. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dustproof sealing device for PTZ cameras, which aims to improve the problems of cumbersome support and inspection in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dustproof sealing device for a PTZ camera, comprising a box bottom, an engagement groove on the inner wall of the box bottom, an engagement plate engaged on the outer wall of the engagement groove, a box body fixedly connected to the right side of the engagement plate, a rotating hole on the right side of the box body, a hollow column slidably connected to the outer wall of the rotating hole, a fixing plate fixedly connected to the right side of the hollow column, a second rotating shaft rotatably connected to the outer wall of the right side of the fixing plate, a pressure plate rotatably connected to the outer wall of the second rotating shaft, a box cover fixedly connected to the outer wall of the pressure plate, and a rotating mechanism fixedly connected to the left side of the box bottom, the rotating mechanism being used to support the device.

[0021] 1. In this utility model, dust prevention measures must be implemented. Open the locking post along the opening of the arc-shaped block. The locking post will rotate with the rotation of the spring post, causing the second movable plate to detach from the arc-shaped block. Since the inner side of the box bottom is equipped with a connecting plate and a locking plate, which are tightly connected to the box bottom, it is necessary to pull the box body so that the box bottom and the box body can be separated. After the operation is completed, you can observe through the hollow post set at the top without taking out the item. Then, slide the box lid towards the fixed plate, so that the box lid can be easily opened.
