The present invention relates to an antenna fixing device and an antenna assembly including the same, and more particularly, when the antenna of the mobile communication equipment is installed on the communication column or the wall, the angle of right and left is easily adjusted, and precisely adjusted to the target minute adjustment angle. The present invention relates to an antenna fixing device and an antenna assembly including the same, which can be fixed and have an advantage of easy installation because of a wider adjustment angle range.

In general, the adjustable angle fixing device for microwave antennas for mobile communication equipment is a means for fixing its directing angle in a fixed direction, and a clamp is fastened to a structure such as a communication column or a wall, and a holder to which an antenna is fastened. The cradle is coupled to the clamp to be rotatable within a certain angle range.

However, such a fixed device capable of adjusting an angle has a complicated configuration, a narrow range of angle adjustment, difficult adjustment of an angle for improving the reception rate of an antenna, and a weak structural problem.

Therefore, a number of antenna fixing devices have been proposed to solve this problem, and there are Korean Patent Registration No. 491536 and Korean Patent Publication No. 10-2005026461, but Korean Patent Registration No. 491536 has a rotational direction. There is a problem that is limited to the top and bottom or left and right, and in order to improve the case has been developed that can be rotated up and down and left and right, one of which is Korea Patent Publication No. 10-2005026461. However, even in this case, when the adjustment angle is adjusted in the direction of the antenna, when the adjustment is completed and fixed, the fixing angle is fixed by bolts and nuts. There is a problem that needs to be fixed again, and even if the antenna is fixed as it is, after the fixing is completed, the actual fixed adjustment angle may not be the desired adjustment angle due to the problem of the backlash of the bolt / nut. In case of fixing the antenna, there is a problem that the adjustment angle is twisted again by the elastic deformation of the fixing device due to the load of the antenna applied to the fixing device itself. There is a problem that the adjustment angle is distorted. Therefore, it is difficult to adjust the antenna with the correct adjustment angle, there is a problem that it is difficult to fine-tune the adjustment angle, there is a problem that it is difficult to maintain this adjustment angle in the adjusted state.

In order to solve the above problems, the present invention is easy to adjust the angle of the left and right when installing the antenna of the mobile communication equipment on the communication column or the wall, it is possible to accurately adjust and fix to the target fine adjustment angle, wider An object of the present invention is to provide an antenna fixing device having an adjustable angle range and easy installation, and an antenna assembly including the same.

In order to achieve the above object, the present invention

Also,

The antenna fixing device; And,

It provides an antenna assembly comprising an antenna coupled to the antenna holder.

Hereinafter, the present invention will be described in detail with reference to the drawings.

The present invention relates to an antenna fixing device, a clamp 10 fixed to a communication column 5 or a wall, a first worm and a worm wheel connected to the clamp 10 so that a vertical axis or a horizontal axis with respect to the ground can be rotated as a first rotation axis. A connecting bracket 30 connected to the connecting portion 20, the first worm and the worm wheel connecting portion 20, and a second worm connected to the connecting bracket 30 so as to be rotatable to a second rotating shaft perpendicular to the first rotating shaft. And an antenna cradle 50 connected to the worm wheel connection portion 40 and the second worm and worm wheel connection portion 40.

Specific embodiments thereof are as shown in FIGS. 1 to 3. That is, in the case of a general antenna, preferably a microwave antenna, it is fixed to the communication column or the wall and has a constant direction or direction. For this purpose, a clamp is provided to fix the antenna to the communication column or the wall.

Of course, the clamp 10 may correspond to various known clamps. The clamp 10 is provided with a connecting portion for rotating the antenna up and down and left and right to adjust the orientation angle of the antenna (adjustment angle from the adjuster's point of view), the present invention comprises such a connection portion worm and worm wheel It is characterized by that. That is, the clamp 10 includes a first worm and worm wheel connection part 20 connected to the clamp 10 so that the vertical axis or the horizontal axis with respect to the ground on which the communication column or the wall surface is fixed is rotated to the first rotation axis. 1 to 3 illustrate a case having a vertical axis with respect to the ground, and the connection order of the rotation shafts is irrelevant. However, when the first rotation axis is perpendicular to the ground, the second rotation axis perpendicular to the ground is a horizontal axis horizontal to the ground. When the first axis of rotation is a horizontal axis on the ground, the second axis of rotation perpendicular to this is a vertical axis perpendicular to the ground. As the worm and the worm wheel constitute a connection part, the worm wheel rotates the antenna when the worm rotates, and when the worm stops rotating, the rotation of the antenna stops in that state without a back lash. As a result, the antenna stops with the correct direction angle, and the adjustment of the adjustment angle is completed at once.

In addition, as described above, the antenna fixing device of the present invention should rotate the antenna both vertically and horizontally so that the second worm and worm wheel connecting portion 40 which rotates perpendicularly to the first worm and worm wheel connecting portion 20 for this purpose. In order to connect the two connecting parts to each other, the connecting bracket 30 is coupled in the middle. The connecting brackets may be connected to the first worm and worm wheel connecting parts and the second worm and worm wheel connecting parts, which are known in various configurations, and are not limited to specific shapes as shown.

Preferably, the worm and the worm wheel are connected to each of the worm and the worm wheel after the predetermined rotation necessary for the adjustment of the adjustment angle is preferably fixed so that no further rotation due to external impact or load for this purpose The first worm and the worm wheel or the second worm and the worm wheel) may further include a fixing part for fixing the rotation of the worm at a predetermined angle. As the fixing part, various fixing methods for fixing the rotation of a known rotating shaft may be applied thereto. Preferably, the fixing part is a fixing part which is fixed perpendicularly to the rotating shaft of the worm, which is a rotating shaft, so that no change in rotation angle occurs. For example, it is preferable that i) the clamping bolt or ii) key / key groove. The clamping bolt is a bolt that is fixed to a fixed part located on the outer circumference of the worm, preferably a cylindrical fixed part surrounding the outer circumference of the worm. The clamping bolt protrudes inwardly from the rotation of the bolt to contact the surface of the worm to fix the worm. Means the clamping bolt, and the key / key groove means a method of fixing the key and the key groove is applied to the fixing of the general rotary shaft.

In addition, preferably, as shown in Figures 1 to 3, the first worm and worm wheel 20 and the second worm and worm wheel 40 are respectively located opposite the engagement portion of the worm wheel of the worm, the front surface is It may have a configuration further comprising a balance plate (26, 46) having a contact surface in contact with a portion of the outer circumferential surface of the worm, and elastic members (28, 48) located on the rear surface of the balance plate (26, 46). In this case, the worm is not completely fixed to prevent rotation anymore. Instead, the worm's rotation is fixed by frictional force due to the contact between the balance plate and the worm by the elastic force of the elastic member. When it is applied, the rotation of the worm occurs to rotate the antenna, and when the rotation force is applied below, it is configured so that the rotation of the antenna does not occur. No additional fixing is required, and simply by rotating the worm, Since the adjustment is completed, the adjustment angle adjustment operation can be made easier. Therefore, the fixing degree of the antenna is determined according to the magnitude of the restoring force generated by the amount of elastic deformation of the elastic member, and the elastic member including the various springs known as the elastic member may be applied thereto. It is better to apply the same number of coil springs.

More preferably, the antenna fixing device of the present invention further includes an elastic member accommodating portion for receiving the elastic members 28 and 48 and located opposite the balance plates 26 and 46, wherein the elastic member accommodating portion is the elastic member. It is preferable to further include a conveyance interval for compressing the member in the balance plate direction. That is, since the restoring force due to the elastic deformation of the elastic member prevents the rotation of the worm, the rotation of the worm must be very difficult after the adjustment angle is set. Therefore, the compression amount must be large and the restoring force must be large. Since this should be possible to some extent, the amount of compression should be relatively low and the restoring force should be relatively low. Therefore, a means for adjusting the restoring force of the elastic member in the assembly after fastening each part may be necessary. To this end, an elastic member accommodating part accommodating the elastic member may move a bottom surface of the elastic member in contact with the balance plate contact end along the balance plate direction along the elastic deformation axis of the elastic member (approaching or spaced apart). It can have a transfer interval (which allows the transfer to be made through a screw or bolt). This is similar to the clamping bolt described above, but there is a difference between the elastic member and the balance plate. Therefore, through this i) when adjusting the adjustment angle to adjust the feed interval to reduce the friction force by the bottom surface is separated from the balance plate, ii) when the adjustment angle is completed, the bottom surface is adjusted by adjusting the feed interval Approaching to the balance plate, the more compression, the greater the restoring force, the greater the friction force between the worm and the balance plate, so that there is no change in the adjustment angle, so it is easy to adjust the adjustment angle and fix it more securely. You can do that.
