Description

Bracket for monitoring camera with improved structure {Bracket for monitoring camera}

The present invention relates to a bracket that enables easy angle adjustment and rigid fixing of a surveillance camera. More specifically, the present invention can be applied to a wire-exposed camera and a wire-hidden camera in common, but also has sufficient rotation even in the case of a wire concealed camera. It is possible to secure an angle, and even for mounting a camera of a heavy body by the rigid fixing force of the rotating shaft for the surveillance camera support for a surveillance camera bracket having an improved structure that can be installed stable without changing the angle.

The general closed-circuit television system, or surveillance camera system, is mainly composed of three elements: an imaging system, a transmission system, and an aquatic system, and is located in public facilities such as houses, roads, parking lots, department stores, banks, and exhibition halls. It is installed to prevent illegal activities or theft, and is used to remotely monitor various facilities and security status.

An imaging system is a system that photographs a subject and converts it into an electric signal. The camera is mainly a TV camera. The type of camera to be selected, the type of lens, and the type of filter are determined according to the purpose. Mounting brackets, camera housings, etc. are required. On top of that, when remote control of the camera body, the lens system, and the positional relationship between the camera and the subject is required, peripheral devices necessary for remote control are attached to the camera. In addition, when special illumination is required for the subject, the imaging system including the installation of the illumination and its control is considered.

Next, a transmission system is a system for transmitting an image signal of an imaging system to a remote place, and transmits an image signal to a target point where an image is to be used, and is divided into wired transmission and wireless transmission. In the case of CCTV, since it is used for a limited purpose, it is often wired, and in the case of wireless, it is often difficult to implement because it requires allocation of radio frequency.

Even in the case of wired transmission, baseband transmission for transmitting an image signal as it is, carrier transmission for modulating a carrier wave, PCM transmission for transmitting pulse code modulation (PCM), and optical communication method using a laser However, depending on the purpose and economy, the most appropriate method is adopted.

In the transmission system, direct signals are not normally processed or switched, but in large systems, video conversion is performed within the transmission system to effectively use a line.

A water system is a system for reproducing and displaying a transmitted video signal, and receiving and reproducing a transmitted video signal. In the water system, in general, the image is not only reproduced, but is combined with other systems such as traffic control, process control, etc., so that image processing, recording, reproducing, hard copying, and information processing devices are performed. Image processing system and the like are used.

In addition, since the information collection center element is not included in many cases, the function as a centralized management center of the control system is often obtained.

The surveillance camera as described above can be checked through a monitor installed in a remote place such as a central control station by photographing the surveillance area, and if necessary to record the surveillance state.

General cameras and dome-type cameras are mainly used as surveillance cameras. For aesthetic reasons, general cameras are used outdoors and dome-type cameras are mainly used indoors.

Such a surveillance camera is generally installed on a ceiling or on an inclined surface or a wall. When the installation surface is not uniform, there is a problem that a phase difference of a photographing image is generated or a distorted image is taken. The bracket for installing the surveillance camera in order to have a structure capable of adjusting the angle and rotation.

The most widely used surveillance camera bracket is divided into a wire exposed bracket as shown in FIG. 9 and a wire concealed bracket as shown in FIG. 10.

9 is provided with a main shaft 101 having a mounting plate 100 at an end thereof, and a fixing member 103 having a tightening bolt 102 at one end of the main shaft 101. Is coupled to the rotating shaft 104 is inserted into the inside of the fixing member 103, the spherical shape of the rotating shaft 104, the housing 105 in which the camera is built in the end of the rotary shaft 104 ) Is fastened.

At this time, after loosening the tightening bolt 102, and set the angle and direction to the desired shooting range of the camera housing in the free rotation state of the fixing member 103 and the rotary shaft 104, the tightening bolt 102 When tightening), the fixing member 103 is pressed down to the main shaft 101 side, and the fixing member 103 and the rotating shaft 104 are to be firmly fixed.

In addition, as shown in FIG. 10, the wire concealed bracket protrudes to form a separate settling member 106 on one side of the mounting plate 100, and has a spherical rotating part in the settling member 106. The rotary shaft 104 is settled, and the rotary shaft 104 is fixed to the fixture 106 by a separate tightening cap 107, and the tightening cap 107 is provided. When loosened, the rotation shaft and the angle adjustment is possible to adjust the state, so after adjusting the camera to the desired angle and direction, tighten the tightening cap 107 is the rotation by the tightening force of the tightening cap 107 Since the shaft 104 is pressurized and fixed, the camera is fixedly installed.

However, in the surveillance camera bracket as described above, the wire-exposed bracket has a structure that fixes the rotation shaft by the tightening bolt on one side, so that the fastening bolt of the tightening bolt is largely difficult to mount a heavy surveillance camera. Since the tightening bolt is limited to the size of 6mm by the rated standard of the surveillance camera bracket, the bolt of the above standard is fixed depending on the artificial force of the installer. The problem will be thrown.

In particular, the surveillance camera by the wire-exposed bracket as described above, because the high risk of cutting the exposed wire in order to interfere with the purpose of installation of the surveillance camera is to use a wire concealed bracket.

It is a structure that pressurizes the rotating shaft by a tightening cap, which is not suitable for installing a surveillance camera on a weight body. The biggest problem is that the angle adjustment range of the rotating shaft has a limited range within 90 ° C. Losing has its drawbacks.

Therefore, in the conventional case, since the wire exposure type surveillance camera and the wire concealment type surveillance camera are used separately, their use is very cumbersome and inconvenient by their use, and both of them have a weak fixing force and a shooting angle from the load on the weight body. There is a limited problem.

The present invention was conceived to eliminate the problems as described above, to form a coupling portion divided into both sides to the front end of the vertical main shaft having a fixed plate on the bottom, and the rotating shaft having a spherical rotation portion inside the locking region By inserting, by fastening the locking earth by a separate fixing bolt,

The locking shaft is firmly fastened by the locking strip, which greatly improves the fixing force, and the divided locking strip makes the adjustment angle of the rotating shaft larger, and it can be used as the wire concealing type and the wire exposed type for ease of handling. And it is an object of the present invention to provide a bracket for a surveillance camera having an improved structure overcoming all the problems of the conventional bracket by giving a reasonable economics.

Hereinafter, preferred embodiments of the present invention will be described.
