Time synchronization tester

The utility model relates to a time synchronization tester which comprises a case and tester elements installed in the case, an air inlet is formed in the top of the case, a dustproof plate is installed at the air inlet, a plurality of dustproof holes are formed in the dustproof plate, an air outlet is formed in the bottom of the case, an air outlet fan is installed at the air outlet, and the tester elements are installed in the case. An air outlet dustproof net is installed on the side, away from the air outlet fan, of the air outlet. During use, the air outlet fan works to blow out hot air in the case from the air outlet, so that heat dissipation of tester elements in the case is facilitated. 本申请涉及一种时间同步测试仪，其包括机箱和安装在机箱内的测试仪元件，所述机箱顶部开设有进风口，所述进风口处安装有防尘板，所述防尘板上开设有若干防尘孔，所述机箱底部开设有出风口，所述出风口处安装有出风风机，所述出风口远离出风风机一侧安装有出风防尘网。使用时，出风风机工作，将机箱内的热风从出风口吹出，有利于对机箱内的测试仪元件进行散热。
