More particularly, the present invention relates to a constructional pole for CCTV, and more particularly, to a constructional pole for CCTV which can easily be installed and maintained in accordance with a site condition, The present invention relates to a constructional pole for a CCTV.

Recently, as the awareness of crime prevention and security has increased, there is an increasing tendency to install CCTV (Closed Circuit Television) in alleys and apartment complexes.

When CCTV is installed inside a building, it can be installed by attaching it to a wall or a ceiling. However, it is not easy to use a building wall of another owner when installing the CCTV outside, and CCTV should be installed at a place away from a building wall or a wall. There is a problem that it is difficult to apply the CCTV in the same manner as the installation inside the building.

For this reason, when a CCTV is installed outside a building, a road in an apartment complex, a park, etc., a round pole-like pole that can support CCTV is generally used, and a pole for CCTV is installed on the ground, CCTV is installed.

A typical CCTV pole is made of metal and has one hollow pole with one pole, and it has a wire for power supply to the CCTV and a signal line for transmitting the photographed image.

However, such a pole for a CCTV is one long cylindrical shape, and generally has a length of about 3 m.

Because of the long length of the pawl, there is an inconvenience in that it is not easy to install and transport due to the length of the long pole, such as when a new CCTV is installed, when a pole is carried, etc., and special equipment must be used.

In addition, there is a drawback in that it is difficult to repair the CCTV if it is necessary to repair the CCTV or to replace the internal wire due to, for example, disconnection of the internal wire.

In addition, when the CCTV is installed on one side of the road, if the CCTV needs to be repaired or replaced, an expensive ladder car is parked on the road and the ladder is raised to repair or replace the CCTV. In this case, the elevated ladder car parked on the road occupies the lane, thereby interfering with traffic flow.

Patent Document (Registration No. 10-0981311) discloses a CCTV which is coupled to a top pole by a fastener; A plurality of pawls capable of ascending and descending by the pressure of air; A multistage pole body incorporating the plurality of pawls; A pressure sensor for sensing the pressure of the multi-pole body; An air compressor for pumping air into the multistage pole body; A controller for receiving the pressure value of the pressure sensor and controlling the air compressor; A pressure selection switch for specifying a pressure value to the controller to determine a pressure value of the multi-pole body; A discharge valve for discharging air of the multi-pole body to lower the raised pole; And a base fixedly coupled to the multi-pole pawl body. When the pressure selection switch selects the set pressure and transmits the set pressure to the controller, the controller operates the air compressor to transmit air into the multi-pole pawl body, When the pressure measured by the pressure sensor reaches the set pressure, the controller stops operation of the air compressor and discharges air to the discharge valve so as to descend the raised pawl, thereby lowering the raised pawl. Although there is an advantage that maintenance is possible on the ground, since the structure is very complicated and it is a stretching method, there is a problem that the length of the lifting and lowering is different, and the stability is lowered.
