Description

Technical Field

[0001] The present application relates to the technical field of radio frequency equipment, and in particular to a fixing device for adapting to various hole spacings. Background Art

[0002] In recent years, with the development of science and technology, wireless communication technology has been fully developed in electromagnetic wave related technologies, and filters are widely used in wireless communication technology. A filter is a frequency selection device that allows specific frequency components in the signal to pass through and greatly attenuates other frequency components. By using this frequency selection function of the filter, interference noise can be filtered out or spectrum analysis can be performed.

[0003] Before the filter is sold, the power filter used in a vibration environment needs to be tested for its vibration resistance because the environments in which various electronic devices are used are different. In the prior art, when testing the filter, the filter is usually fixed on a workbench on a vibration table, and the vibration table is started to test the filter.

[0004] When fixing the filter, screws are usually used to penetrate the mounting holes reserved on the filter and the threaded holes on the workbench to install the filter on the workbench. However, for filters of different specifications, the sizes of the mounting holes reserved thereon are different, and the sizes of the mounting holes and the threaded holes reserved on the workbench may be different, which makes it difficult to install the filter on the workbench, so further improvement is needed.

The fixing tool for adapting to various hole spacings includes a mounting arm arranged on the workbench, a mounting piece for installing the mounting arm on the workbench, an adapter plate arranged on the mounting arm, and a fixing piece for installing the filter on the adapter plate. The adapter plate is provided with a plurality of second threaded holes of different sizes. The fixing piece is a fixing bolt threadedly connected to the second threaded hole. The filter is provided with a mounting hole reserved for the fixing bolt to pass through.

[0008] By adopting the above technical solution, an adapter plate is provided, and since a plurality of threaded holes of different sizes are provided on the adapter plate, the adapter plate can be adapted to the aperture sizes of the mounting holes reserved on different filters. The mounting arm is mounted on the workbench through the mounting part, so that the filter is indirectly mounted on the workbench, thereby improving the adaptability between the filter and the workbench, and also saving the cost of tooling processing for each aperture size.

[0009] Preferably, the mounting arm is provided with a positioning groove along its length direction, and a limiting convex strip is protruded from the side wall of the mounting arm located at the positioning groove, and the bolt portion of the mounting bolt abuts against the limiting convex strip.

[0010] By adopting the above technical scheme, since the number of mounting holes reserved on different filter plates is different, in order to improve the vibration test accuracy of the filter, it is also necessary to provide a number of corresponding fixing fixtures. Since the spacing between the mounting holes on the filter is fixed, positioning grooves are provided along the length of the mounting arm, so that the position adjustment between the mounting arm and the operating panel can be increased. Since a number of fixtures are provided, adjacent mounting arms are restrained to fix the filter installed on the adapter plate, so as to improve the adaptability between the filter and the workbench.

[0011] Preferably, opposite side walls of the mounting arm are protrudingly provided with abutment plates abutting against the workbench.

[0012] By adopting the above technical solution, an abutment plate is provided to press the mounting arm, so that the first bolt is passed through the positioning groove and threadedly connected with the first threaded hole.

[0013] Preferably, an inclined surface is provided on the abutment plate, and the area of ​​the abutment plate in the cross section gradually increases toward the side wall close to the mounting arm.

[0014] By adopting the above technical solution and providing an inclined surface, when the hand presses the abutment plate, the contact area between the hand and the abutment plate can be increased, so as to increase the pressing effect on the installation arm.

[0015] Preferably, one end of the mounting arm is fixedly connected to a positioning annular boss, a positioning bolt is passed through the middle of the adapter plate, and the positioning bolt is threadedly connected to the positioning annular boss.

[0016] By adopting the above technical solution, a positioning ring boss is provided, a positioning bolt is passed through the middle of the adapter plate, and the positioning bolt is threadedly connected to the positioning ring boss so that it can be disassembled to replace the adapter plate with other aperture sizes, thereby further improving the adaptability between the filter and the workbench.

[0017] Preferably, a positioning convex ring is protrudingly provided on the upper surface of the positioning circular ring boss in the middle, and a positioning ring groove for inserting the convex ring is opened on the lower surface of the adapter plate.

[0018] By adopting the above technical solution, by providing a positioning convex ring and annular groove, the positioning effect between the positioning circular ring boss and the adapter plate is accelerated, and the replacement rate of the positioning circular ring boss that needs to be replaced is accelerated.

[0019] Preferably, the adapter plate is provided with a notch which is connected to the positioning groove.

[0020] By adopting the above technical solution, when several of the toolings are provided, the spacing between adjacent reserved holes is small, while there is a certain spacing between the positioning grooves on the connecting arms in adjacent toolings. The positioning grooves may be installed at one end of the adapter plate close to the adapter plate. Therefore, a notch is opened on the adapter plate to facilitate the installation of bolts to penetrate and be screwed to the first threaded hole on the workbench.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. An adapter plate is provided. Since a plurality of threaded holes of different sizes are provided on the adapter plate, the adapter plate can be adapted to the aperture sizes of the mounting holes reserved on different filters. The mounting arm is mounted on the workbench through the mounting piece, so as to indirectly mount the filter on the workbench, thereby improving the adaptability between the filter and the workbench and saving the cost of tooling processing for each aperture size.

[0023] 2. Connecting several positioning grooves to form a positioning groove can increase the position between the mounting arm and the operating panel so as to adjust according to the spacing between the mounting holes on the filter to improve the adaptability between the filter and the workbench.

[0024] 3. A positioning ring boss is provided to facilitate disassembly and replacement of adapter plates with other aperture sizes, thereby further improving the adaptability between the filter and the workbench. BRIEF DESCRIPTION OF THE DRAWINGS
