Description

  The present invention relates to a waterproof traffic signal controller.

  A traffic signal controller that controls a traffic signal installed at an intersection or the like is generally housed in a dedicated housing locked with a police lock and fixed to a post standing on the side of a road ( For example, see Patent Document 1). In recent years, traffic signal controllers are known that have been provided with waterproofing measures so that their functions can be maintained even when roads are flooded and submerged due to river flooding or the like.

For example, FIG. 5 is a perspective external view showing a configuration example of a conventional traffic signal controller.
The waterproof traffic signal controller 90 incorporates electrical and electronic parts (not shown) such as an electronic circuit, a relay, and an electromagnetic switch in a housing 91, and electrical wiring (not shown) is passed through a cable bush or the like. It is inserted through the opening 99 at the bottom of the housing. The main door 92 is closed via a waterproof packing. When the door is closed, the main door 92 is fastened to the housing 91 with three patch locks 94. Thereby, high airtightness is ensured except for the opening 99 at the bottom of the housing.

  If water damage occurs and the water level rises to the installation position of the waterproof traffic signal controller 90, water will be submerged from the opening at the bottom of the housing, but the air pressure of the air remaining inside the housing will increase due to water immersion. In the course of time, the water pressure and the air pressure are balanced, so that the inundation into the housing stops. Since the electric / electronic parts are not disposed in the lower layer inside the casing 91 that may be flooded, they are not exposed to water.

  As a fastener for fastening the main door 92 to the housing 91, a patch-on lock 94 having a high fastening force is generally employed from the viewpoint of ensuring airtightness. As the patch lock 94 employed, there is a case in which a lock type is used to prevent mischief and the like. From the viewpoint of security, as shown in FIG. 5, there is known a patchon lock cover 96 having a police lock 95 attached to one patch lock 94.

Utility Model Registration No. 3005340

The conventional waterproof traffic signal controller 90 requires a large number of keys to open the main door 92, so that a high degree of security is provided, but there is a problem in maintenance.
Specifically, in order to open the main door 92 at the time of inspection and maintenance, it is necessary to unlock the police lock 95, open the patch lock cover 96, and further unlock the patch lock 94, which is complicated. . The same applies when the main door 92 is closed. If all the patch locks 94 are of the keyless type, the key becomes one key of the police lock 95, and there is no need to carry a plurality of keys, and the time for locking / unlocking associated with opening / closing can be reduced. However, if the patch lock 94 that is not protected by the patch lock cover 96 is opened with mischief, the airtightness is impaired and the waterproof performance may be deteriorated.

  The traffic signal controller is installed with the side surface of the housing 91 fixed to a support column. Since the thickness and the position of the column vary depending on the site where the traffic signal is installed, it is up to the site whether it is actually fixed on the left or right side of the housing 91. However, the patch-on lock cover 96 of the conventional waterproof traffic signal controller 90 is provided on the side of the casing 91, and even the pine swings sideways and opens and closes. Therefore, depending on the thickness of the support and the positional relationship, it may be difficult to open the patch lock cover 96.

  A first device for solving the above-described problem is a waterproof traffic signal controller that is provided with a main door that can be freely opened and closed via a waterproof packing, and is a side surface opposite to a rotating shaft that supports the main door.

In addition, the patch lock cover is structured to swing open to the front side. Therefore, when the waterproof traffic signal controller is fixed to the column, the patch lock cover can be easily opened and closed regardless of the thickness of the column and the positional relationship with the column.

  A third device is the waterproof traffic signal controller according to the first or second device, wherein a key insertion port of the police lock is provided on the front side of the housing.

  The conventional type that inserts the police lock from the side may be difficult to operate due to the relationship with the support, but the waterproof traffic signal controller of the third device is inserted from the front, so easy key operation is guaranteed. Is done.

  According to a fourth aspect of the invention, the main door has the patchon lock cover and the front cover on the front side, and the front face of the patchon lock cover and the front face of the front cover are flush with each other when the patchon lock cover is closed. Alternatively, it is a waterproof traffic signal controller according to any one of the first to third devices, which is substantially flush.

  Traffic signal controllers are often installed beside the sidewalk where people come and go with the front facing the sidewalk. According to the fourth device, since the unevenness on the front side can be reduced, it is excellent in design, and it is possible to prevent injuries when a person coming and going contacts the front of the waterproof traffic signal controller. Demonstrate the effect.

  According to a fifth aspect of the present invention, the patch lock cover is connected to a side surface of the front cover by a hinge, and the hinge of the patch cover lock facing the side surface of the front cover and the side surface of the front cover when the patch lock cover is closed. It is a waterproof traffic signal controller of the 4th device accommodated between side surfaces.

  According to the fifth aspect, the hinge can be protected without affecting the shape of the front side.
