Description

  The present invention relates to an attachment device, and more particularly, to an attachment device that can easily attach an antenna and can cope with the antenna even when the antenna is attached to a pole, wall, or ceiling.

As shown in FIG. 14, the conventional antenna mounting device includes a mounting bracket 101 formed in a “U” shape when viewed from above, a U bolt 102 and a nut 103 for fixing the mounting bracket 101 to the pole 8, and an antenna. 7 and a pair of connecting metal fittings 105 fixed by bolts 104, and bolts 106 and nuts 107 for connecting the metal fittings 105 and the mounting metal fittings 101.
Although this antenna mounting device 100 has a simple shape of the connecting bracket 105, the mounting bracket 101 and the connecting bracket 105 must be connected by the bolt 106 and the nut 107, and workability is poor.

By the way, various techniques for improving the mounting workability have been proposed.
For example, there is a technology of an outdoor communication device mounting structure in which a fixing member fixed by screws with a mounting pole interposed therebetween is temporarily fixed by providing a hinge mechanism and a temporary fixing mechanism (see, for example, Patent Document 1). .)

  In addition, the antenna mounting device technology in which the second holder is fixed to the first holder with one touch while the antenna pole is sandwiched, and the first holder is provided with a pressing piece biased by an elastic body that presses the antenna pole. (For example, refer to Patent Document 2).

Japanese Patent Laid-Open No. 11-145713 (first term, FIG. 1) JP 09-294010 A (1st term, FIG. 2)

  In recent years, antennas have been reduced in size and weight, and their functions and usage scenes have been diversified. Furthermore, antennas have generally been attached to poles, but cases where they are installed on places other than poles, such as wall surfaces and ceilings, are also increasing.

However, although the outdoor communication device mounting structure technology can temporarily fix the fixing member when mounting the outdoor communication device on the mounting pole, it is necessary to screw the fixing members to each other, and the workability is poor. There was a problem.
In other words, there are many places where antennas are installed, such as poles, where it is difficult to work, so in order to minimize installation work in consideration of work safety, it is safe and reliable without using screws during installation. In addition, there has been a demand for simple installation work.

Also, the antenna mounting device technology allows the antenna to be mounted on the antenna pole without screwing, but cannot be mounted on the wall or ceiling. However, there was a problem that it could not be shared. Furthermore, since the antenna mounting device 100 is a mounting device using a U-bolt 102 dedicated to pole installation, a separate mounting device is required for installation on a wall surface.
That is, there is a need for a sharable mounting device that does not require different types of mounting devices depending on the installation location, and that can handle all mounting environments with the minimum required mounting devices.

  The present invention has been proposed in order to solve the above-described problems of the prior art, and an attachment such as an antenna can be easily attached, and the attachment location is a pole, a wall surface, a ceiling, or the like. However, an object is to provide a mounting device that can be shared.

  To achieve the above object, the mounting device of the present invention is a mounting device including a mounted member fixed to a mounted body, and a mounting device fixed to an attachment and attached to the mounted member, A locking plate provided on the mounted member and / or mounting tool and having a cross-section bent in a bowl shape, and provided on the mounting tool and / or mounted member facing the locking plate, A locking plate formed with a guide portion into which the locking plate is inserted, and when the locking plate is rotated or moved in a state of being inserted into the guide portion, the locking plate is locked to the locked plate. The configuration is as follows.

  Moreover, the attachment apparatus of this invention is set as the structure which used the said attachment as the antenna.

  Moreover, the attachment apparatus of this invention is set as the structure by which the said latching plate of the latched state is pressed on the back surface of the said to-be-latched plate.

  Further, the attachment device of the present invention is configured such that the attached member has a rectangular box shape without a bottom plate, and a notch having a shape corresponding to the attached surface of the attached body is formed on the opposing side plate.

  Moreover, the attachment apparatus of this invention is set as the structure which provided the flange in which the fixing hole for fixing to the said to-be-attached body was formed in the side plate which the said to-be-attached member opposes.

  Moreover, the attachment apparatus of this invention is set as the structure provided with the clamping member connected with the said to-be-attached member so that the said to-be-attached body may be pinched | interposed.

  In addition, the attachment device of the present invention is configured to include positioning means for determining the position of the locking plate used when rotating or moving the locking plate inserted into the guide portion.

According to the attachment device of the present invention, the attachment can be attached to the to-be-attached attachment easily and in a short time. For this reason, even if the installation location is a place where work is difficult, such as a pole, a wall surface, or a ceiling, it is possible to work safely.
Further, according to the mounting device of the present invention, for example, it is possible to cope with different installation locations such as poles, wall surfaces, ceilings, etc., so it is not necessary to change the type of the mounting device depending on the installation location, and the minimum necessary installation The device can handle different installation environments.
Furthermore, it is possible to safely and easily attach an antenna that is often installed at a place where it is difficult to work, such as a pole, a wall, or a ceiling.

According to the mounting device of the present invention, since a frictional force is generated between the locking plate and the locked plate, it is ensured that the locking plate moves due to vibration or the like, and the attachment falls off. Can be prevented.
Further, even if the mounted body is a pole or the like, the mounted member can be firmly fixed.
Furthermore, even when the mounted body is a wall or a ceiling, the mounted member can be firmly fixed using screws or the like.

According to the mounting device of the present invention, even if the mounted body is a pole or the like, even if the mounted member is not formed in a dedicated shape for fixing to the pole or the like, it can be handled by using a pinching member. Therefore, the mounted member can be shared.
Further, the positional accuracy of the attachment and the attached body can be improved, and the positioning operation can be improved and the work efficiency can be improved.

  Next, a preferred embodiment of the antenna mounting device of the present invention will be described with reference to the drawings.
