Description

Technical Field

[0001] This utility model relates to the field of communication technology, specifically to a clamping device for an antenna support adjustment structure assembly. Background Technology

[0002] With the rapid development of communication technology, more and more antenna equipment is being installed on base stations. This antenna equipment uses electrically adjustable brackets to adjust the azimuth and elevation angles. The adjustment function of these brackets requires an adjustment structure assembly. This assembly mainly consists of a horizontal fixing base, a horizontal adjusting component, and a rotating pin, etc. Figure 3 The rotating pin has a directional groove, and there is a relatively accurate angular positional relationship between the directional groove and the horizontal fixed seat.

[0003] During the production process, drilling, reaming, and assembling tapered pins can lead to product angle deviations, low precision, and low production efficiency due to inaccurate machining positions.

[0004] To address these shortcomings, an antenna support adjustment structure component clamping device was proposed, and the device was upgraded and modified to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the background technology by providing a clamping device for the antenna support adjustment structure component.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An antenna bracket adjustment structure assembly clamping device includes a base. A support plate is fixedly connected to the upper surface of the base. A concave connecting block is fixedly connected to the upper left side of the support plate. A movable arm is rotatably connected to the inner side of the concave connecting block. A lead screw is threadedly connected to the inner wall of the upper end of the movable arm. A handle is slidably connected to the upper end of the lead screw outside the movable arm. A clamping block is rotatably connected to the lower end of the lead screw outside the movable arm. A horizontal fixed seat abuts against the surface of the base. A horizontal adjustment component is provided on the upper side of the horizontal fixed seat near the support plate. A rotating pin is rotatably connected to the inner wall of the horizontal adjustment component. A positioning post is sleeved on the inner wall of the rotating pin. The end of the positioning post away from the rotating pin is fixedly connected to the surface of the support plate. A retaining ring is provided on the upper side of the horizontal fixed seat near the clamping block. One end of the rotating pin passes through the horizontal fixed seat and is connected to the inner side of the retaining ring.

[0008] Furthermore, positioning strips are fixedly connected to both sides of the outer end of the positioning column, one end of the positioning strip is fixedly connected to the outer end of the support plate, and a directional groove is provided at the end of the rotating pin near the support plate.

[0009] Furthermore, tapered pins are threaded onto both sides of the upper end of the leveling component.

[0010] Furthermore, a hinge hole is provided on the upper surface of the horizontal fixing seat, and a cylindrical pin is inserted into the inner wall of the hinge hole.

[0011] Furthermore, one end of the horizontal adjusting member and the end of the horizontal fixing seat near the horizontal adjusting member are provided with scale markings.

[0012] Furthermore, a limit pin is fixedly connected to the side of the base near the horizontal fixed seat.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention aligns the central rotating pin of the horizontal adjusting component with the positioning post (with the movable arm open), fits the large circular hole in the center of the rotating pin onto the positioning post, closes the movable arm, and rotates the lower part of the horizontal fixed seat until it is in contact with the limiting pin (as shown in the figure). The rotating handle drives the lead screw to rotate, causing the lead screw to move the clamping block towards the horizontal fixed seat, securing the snap ring onto the rotating pin and tightening the horizontal adjusting component and the horizontal fixed seat. This allows for drilling (reaming) the upper end of the horizontal fixed seat through the cavity in the center of the movable arm surface using a drilling device, and also facilitates inserting the cylindrical pin into the reamed hole and installing the conical pin on the horizontal adjusting component. This enables accurate angle positioning and improves production efficiency. Attached Figure Description
