Description

[Detailed Description of the Invention] "Purpose of the Invention" The present invention relates to an antenna connection mechanism that can vary the setting angle, and relates to the base end of a rod-like body such as an antenna installed in a wireless communication mobile station. The purpose of the present invention is to provide a mechanism that can be separated and connected without the need for tools, change the setting angle as appropriate, and stably fix the mechanism at any selected angle.

Industrial application field A mounting mechanism for a rod-shaped body made of pipe or rod material that is formed to protrude from the surface of a car body, such as an antenna for a wireless communication mobile station installed in a car.

PRIOR TECHNOLOGY For in-vehicle wireless communication equipment, antennas such as rod antennas have been installed protruding from the car body wall in various ways. It is preferable to vary the mounting angle, and even if the receiving angle is the same, the angle relative to the vehicle body surface needs to differ depending on the mounting position on the vehicle body.

For this reason, there are two conventional technologies that have been used: one is to raise and lower the device using a mounting bracket for attaching it to the vehicle body, and the other is to raise and lower it on the antenna side at the top using this mounting bracket. In the case where the antenna is raised and lowered, it is necessary to take measures to deal with this as the cables connected to the antenna are affected to some extent when the antenna is raised and lowered. do not have. That is, examples of devices in which the antenna is raised and lowered on the side of the antenna on the mounting bracket are disclosed in Japanese Utility Model Publication No. 56-16810 and Japanese Utility Model Application Publication No. 59-14403.

Problems to be Solved by the Invention However, the above-mentioned conventional devices still have their own problems.

That is, in each of these items, the antenna support rod or the like is pulled out from the mounting bracket or the shaft cylinder member attached to the shaft cylinder member together with the slide member pivotally connected to the lower end of the rod, and the pivot part is attached to the shaft cylinder member. Since the antenna support rod is pulled out from the shaft and lies down, and the antenna support rod which has fallen down is retained in the state of being locked to the upper edge of the shaft tube member, the pivoting portion is pulled into the shaft tube member. Only two states are formed: the vertical state in which it is pulled out and the state in which it is pulled out and laid down at right angles as described above, and no other state can be taken. Even if an intermediate state is adopted, it is unstable. However, the antenna is generally mounted on an inclined surface at the top of the side of the vehicle body for reasons such as ensuring visibility when driving the vehicle, and it is difficult to install the antenna at a right angle on such an inclined surface. Vehicle equipment condition is not favorable. In addition, even if the mounting bracket is installed so that the joint surface of the vehicle body is inclined so that it can be raised and lowered in a vertical plane on the inclined surface of the side top of the vehicle body, the height of the mounting bracket must be set according to the antenna reception or vehicle driving conditions. Alternatively, as for the setting direction, it is often preferable to adopt a certain degree of inclination within the vertical plane, but the conventional device as described above is not suitable for adopting such an inclination.

"Structure of the invention" Means for solving the problem Engagement teeth are formed on a base member to which an antenna is attached, the engagement tooth portion of the base member is pivotally attached to a support body, and A locking element having a locking part that engages with and disengages from the engaging teeth is accommodated in the fitting hole formed therein, and a guide part formed on the locking element is inserted into a guide formed in the fitting hole. a split groove is formed in the support body from the bottom surface side, and a horizontal groove is formed symmetrically from the upper end of the split groove, and A horizontal groove is formed symmetrically from the upper end of the groove, and a rotary operation body is fitted into such a support body, and a rod-shaped connecting portion that fits into the split groove is provided in the inner hole of the rotation operation body. and a seat for supporting the locking element is formed in an intermediate portion of the rod-like connecting portion, and the rotation operation is performed between the seat and a partition wall of the intermediate cylinder attached to the bottom of the support body. An antenna connection mechanism capable of varying a set angle, characterized in that an elastic member is provided to apply an elastic force to act on the locking member in the direction of the engagement teeth through the member.

Function: The engagement teeth of the base member to which the antenna is attached and the engagement portion of the engagement element accommodated in the fitting hole of the support body are engaged and disengaged.

The locking element is supported on a seat in the rod-like connecting part of the rotating operation part body which is fitted into the split groove and the lateral groove of the support body.

Since the rod-shaped connecting portion is located in the split groove area, the rotation operation body and the locking element are movable in the vertical direction. Therefore, in this state, the locking part of the locking element is in contact with the engagement teeth. The base body formed in a removable relationship with the antenna and to which the antenna is attached can change its set angle as appropriate.

Elastic pressure that acts on the locking element in the direction of the engagement teeth of the base member via the rotation operation body between the catch of the locking element and the partition wall of the intermediate cylinder attached to the bottom of the support body. By providing an elastic material for applying force, the locking element always has an acting force that locks onto the engaging teeth of the base member, and the above-mentioned locking relationship is immediately established when the setting angle of the base member to which the antenna is attached is changed. It is formed.

When the rotation operation part body rotates and its rod-shaped connecting part is located in the horizontal groove, the height position of the rotation operation part body and the locking element in the above-mentioned support body is fixed, and the locking part The engagement position between the locking portion and the engagement tooth of the base member is locked. That is, the set angle of the antenna is fixed.
