Description

[Detailed description of the invention] A pole-mounted switch attached to a telephone pole, etc. is structured to be opened and closed by a lever, and seine nets are attached to both ends of this lever, so that it can be opened and closed by operating the seine net from below. .

By providing such a seine on a pole switch, the switch can be opened and closed without getting close to high-voltage power lines, making it extremely safe to open and close the switch.

However, if the utility pole is close to a tall building,
There is the problem of malicious pranks being carried out by people reaching out from buildings and pulling the dragnet to turn off the switch and cause a power outage.

In order to prevent such mischief, some seine nets are wound around multiple protruding shafts attached to utility poles, and then the lid is bolted on. However, this method requires manual operation of the seine net. When this occurs, it is necessary to remove the bolts, open the lid, expose the protrusion shaft, and remove the seine net from the protrusion shaft, which is a tedious task, and it is also time-consuming to secure the seine net. .

In view of these problems, this invention provides a device that can fix or free the seine with a single touch.

In other words, this idea involves fixing a receiving frame to a utility pole, etc., to receive the dragnet hanging from a pole-mounted switch attached to a utility pole, etc., and inserting both sides of the supporting frame, which protrudes from the center of the receiving frame, into a pair of vertical elongated holes on the left and right in the center of the push plate. A cam that moves the push plate forward and backward is rotatably attached between both sides of the support frame that protrudes outside the push plate, and a rotating lever is attached to this cam. The seine net is attached to the receptacle frame and is fixed by pressing the seine to the receiving frame during normal times by rotating the cam by operating the lever and moving the push plate forward and backward, making it impossible to operate the seine from below. It is something.

An embodiment of the fixing device of this invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a utility pole, to which a receiving frame 2 made of steel plate or the like is fixed. Although the means for fixing the receiving frame 2 to the utility pole is arbitrary, in the illustrated example, a band 3 such as a steel plate is wound around the utility pole 1, and this band 3 is inserted into the engagement hole 4 of the both side walls 5 of the receiving frame 2. Both ends are integrally connected to the utility pole 1 using appropriate connectors.

A support frame 6 bent in a U-shape is fixed to the center of the front surface of the receiving frame 2, and both side pieces of the support frame 6 are loosely fitted into a pair of left and right vertical holes 8 at the center of a push plate 7.

A cam 9 is rotatably fitted between the left and right pieces of the support frame 6 protruding outside the push plate 7, and its shaft 10
are rotatably attached to the left and right sides of the support frame 6.

A lever 11 is fixed to the outer periphery of the cam 9, and when the lever 11 is turned upward, the cam 9 is eccentrically moved outward, and when the lever 11 is turned downward, the cam 9 is eccentrically moved toward the receiving frame 2. A support piece 13 fixed to the upper part of the plate 7 and a lower outer surface of the push plate 7 are provided with locking clips 14 and 15 for the lever 11.

The center part of the spring 16 is fixed inside the support frame 6, and its upper and lower ends are bent forward and pressed against the rear surface of the push plate 7, thereby pushing the push plate 7 forward and press against the outer periphery of the cam 9.

A pair of left and right guides 17 are fixed to the upper and lower portions of the receiving frame 2, respectively. A seine net 12 hanging down from both ends of the operating lever of a pole-mounted switch (not shown) is loosely inserted into the guide 17, and the seine net 12 is passed between the receiving frame 2 and the push plate 7.

In addition, in the illustrated example, opposing unevenness is provided on the front surface of the receiving frame 2 and the rear surface of the push plate 7, so that the push plate 7 can hold the dragnet 1.
2 is crimped onto the receiving frame 2, the seine net 12 is bent as shown in FIG.

Next, to explain the operation of the above embodiment, the first
When the lever 11 is turned upward and engaged with the upper clip 14 as shown in FIGS.
Since it is eccentrically downward and outward, the push plate 7 is pushed outward by the spring 16.

Therefore, the seine net 12 can freely move up and down between the receiving frame 2 and the push plate 7, so the pole switch can be opened and closed freely.

Next, remove the lever 11 from the clip 14,
When rotated downward to engage the clip 15, the cam 9
The lever also rotates together with the lever 11 to push the push plate 7 toward the receiving frame 2, and as shown in FIG. 3, the seine net 12 is tightened between the receiving frame 2 and the push plate 7 to fix it so that it does not move.

In this invention, as mentioned above, by rotating the cam 9 with the lever 11, the seine net 12 can be placed in a free state or a fixed state.
By fixing the seine net 12 with the seine net 1 facing downward, there is no possibility that the seine net 12 will be manipulated by mischief.

In addition, when the lever 11 is turned upward, the dragnet 1
2 can be operated freely, so when doing construction, etc., all you have to do is open and close the switch in this state. In addition, if the outer end of the lever 11 is made into a ring shape as in the illustrated example, the lever 11 can be operated by preparing a rod with a hook at the tip and hooking the hook of this rod onto the ring-shaped portion of the lever 11. Therefore, it is convenient.

As mentioned above, this idea involves fixing a receiving frame to a utility pole, etc., to receive the dragnet hanging from a pole-mounted switch attached to a utility pole, etc., and attaching both sides of the supporting frame that protrudes from the center of the receiving frame to the left and right sides of the center of the push plate. The drag net is inserted loosely into a pair of vertical holes and inserted between the support frame and the push plate, and a cam for moving the push plate forward and backward is rotatably installed between both sides of the support frame protruding outside of the push plate. Since a rotating lever is attached to the lever, the push plate moves forward and backward with a single touch operation due to the rotation of the cam by the lever, fixing or freeing the seine between the receiving frame and the push plate. It has the unique effect of being able to fix and release seine nets much more easily and quickly than with net fixing devices.
