Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a film threading device for an antenna radome film material. Background Art

[0002] To ensure that the antenna works all-weather in harsh environments such as rain and snow, an antenna radome needs to be set to enclose the antenna. Usually, the film material is threaded and fixed in a triangular frame to form a film locking member as shown in Figure 1 The antenna radome spherical surface is composed of one film locking member after another to protect the internal antenna. The triangular frame is composed of three pressing plates. The film material is also set as a triangle, and the edges of each side are threaded through the cavities of each pressing plate for fixation. The film material not only needs to play a protective role but also meet the requirement of transmitting electromagnetic waves. The smoother the surface of the film material, the lower the electromagnetic wave loss of the antenna.

[0003] At present, the threading of the antenna radome film material is mostly carried out manually, which not only has low efficiency, but also is difficult to control the threading force and direction, often causing wrinkles on the film surface after threading, affecting the transmission of electromagnetic waves of the antenna. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a film threading device for an antenna radome film material with high efficiency and a smooth film surface.

[0005] To solve the above technical problem, the utility model adopts the following technical solutions:

[0006] A film threading device for an antenna radome film material, including a transmission component, a slide rail component, a film pressing component and a platform. The film pressing component is fixedly arranged on the platform. During film threading, the film pressing component presses and fixes the film material on the platform. A pressing plate for fixing and tensioning the film material is arranged on the slide rail component. The transmission component drives the slide rail component to drive the pressing plate to move, so that the edge of the film material is threaded through the cavity of the pressing plate.

[0007] As a further improvement of the above technical solution:

[0008] The edge of the film material is folded by a steel wire, and the film pressing component presses and fixes the folding part on the platform.

[0009] The film pressing component includes a support frame, an electric push rod and a backing plate. The support frame is fixedly installed on the platform. The electric push rod is fixedly installed on the cross beam of the support frame. The backing plate is fixedly installed at the end of the push rod of the electric push rod and is parallel to the plane of the platform.

[0010] A layer of rubber plate is also fixedly installed under the backing plate.

[0011] The transmission assembly includes a motor and a lead screw. The lead screw is connected to the motor through a gear pair and is movably connected to the slide rail assembly through a bearing.

[0012] The slide rail assembly includes a slide rail, a slider, and a support plate. The slider is slidably connected to the slide rail. The support plate is fixedly installed on the slider. A number of connecting rods for installing the pressing plate are formed on the support plate. A nut threadedly connected to the lead screw is also fixedly provided on the slider.

[0013] The support plate is set as a metal plate. A hole for inserting and mating with the connecting rod is formed on the pressing plate. The pressing plate is hung on the support plate and is tightly fixed by a magnet.

[0014] It further includes a touch switch provided on the platform.

[0015] Compared with the prior art, the advantages of the present utility model are as follows:

[0016] For the film threading device of the radome film material of the present utility model, during use, the film material to be threaded is placed on the platform and the edge of one side thereof extends out of the platform. The film material is pressed by the film pressing assembly to prevent it from loosening. Then, the pressing plate is installed on the slide rail assembly. The slide rail assembly is driven by the transmission assembly to drive the pressing plate to move, so that the film material extending out of the edge of the platform is threaded into the cavity of the pressing plate to complete the film threading. Compared with manual film threading, the structure of the present utility model is simple. The film threading is realized by driving the pressing plate to move by the slide rail assembly. Its operation is stable and the efficiency is higher, thereby ensuring stable and reliable film threading, avoiding wrinkles on the film surface after film threading, ensuring the film surface is flat and smooth, and reducing the loss during the transmission of electromagnetic waves.
